QUESTIONS AND ANSWERS ABOUT THE ACQUISITION

Q: Why is Stamps.com proposing to acquire iShip.com?

A: This is a unique opportunity to acquire a complementary shipping business
which will provide Stamps.com the opportunity to offer a complete one-stop
mailing, shipping and tracking solution over the Internet.

Q: Why is iShip.com proposing to be acquired?

A: The acquisition will allow iShip.com's shareholders to obtain liquidity and
participate in the creation of a leading provider of Internet postage and
shipping services.

Q: If Stamps.com is not itself merging why are Stamps.com's stockholders being
asked to vote?

A: Stamps.com's common stock is traded on the Nasdaq National Market, which
requires that Stamps.com's stockholders approve the merger agreement because
at the time the merger agreement was executed, the consideration offered by
Stamps.com in the acquisition potentially represented more than twenty
percent of Stamps.com's outstanding shares of common stock. It is necessary
for Stamps.com's stockholders to approve the proposed increase in options
available for grant in order for those options to be eligible for favorable
tax treatment.

Q: Can Stamps.com stockholders change their vote after they have sent a proxy
authorization?

A: Yes. A vote can be changed at any time before the proxy is voted at the
special meeting. This can be done in one of three ways. First, you can send
a written notice stating that you would like to revoke your proxy. Second,
you can complete and deliver a new proxy. If you choose either of these two
methods, you must submit your notice of revocation or your new proxy to
Stamps.com's Secretary at 3420 Ocean Park Blvd., Suite 1040, Santa Monica,
California 90405. Third, you can attend the Stamps.com special meeting and
vote in person.

Q: If my Stamps.com shares are held in "street name" by a broker, will the
broker vote the shares for the shareholder?

A: The broker will vote the Stamps.com shares only if they are provided
instructions on how to vote. Follow the directions provided by the broker
regarding how to instruct the broker to vote the shares. Without
instructions, the shares will not be voted.

Q: When do you expect the acquisition to be completed?

A: Stamps.com and iShip.com are working to complete the acquisition as soon as
possible. Stamps.com and iShip.com expect to complete the acquisition during
the first quarter of 2000.

Q: Who can help answer my questions?

A: If you have questions about the acquisition or if you need additional copies
of this document or the enclosed proxy or written consent, you should

Stamps.com offers a convenient, cost-effective and easy-to-use service for
purchasing and printing postage over the Internet. Stamps.com's core service is
approved by the US Postal Service and enables users to print information-based
indicia, or electronic stamps, directly onto envelopes, labels or business
documents using ordinary laser or inkjet printers. Stamps.com's service is
currently the only commercially available offering that requires no additional
hardware to purchase and print postage; the user's existing PC, printer and
Internet setup are sufficient. Accessing the Stamps.com service is simple.
Stamps.com's free software can be downloaded from the Internet or installed
from a free CD-ROM. After installing the software and completing a brief
registration process, customers can purchase and print postage 24 hours a day,
seven days a week from their PCs. Customers are charged a monthly convenience
fee based on their usage of service. Stamps.com's technology meets strict US
government security standards and our service incorporates US Postal Service-
mandated address verification features to enhance the efficiency of mail
processing and delivery. In addition, Stamps.com's Internet Postage(TM) service
is designed to interact with word processing, contact and address management,
accounting and corporate applications to stamp letters, invoices, statements,
checks and other business documents automatically.

On October 22, 1999, Stamps.com commercially launched its Internet Postage
service. Stamps.com was incorporated in Delaware as StampMaster, Inc. in
January 1998 and changed its name to Stamps.com Inc. in December 1998.

Comparative Per Share Data

The following tables present unaudited historical and pro forma per share
data that reflect the completion of the acquisition based upon the historical
financial statements of Stamps.com and iShip.com. The pro forma adjustments are
based upon available information and assumptions Stamps.com believes are
reasonable in the circumstances. The pro forma data are not indicative of the
results of future operations or the actual results that would have occurred had
the acquisition been consummated at the beginning of the periods presented. You
should read the data presented below together with the historical consolidated
financial statements, including applicable notes, and the unaudited pro forma
condensed combined financial data.

The average common shares outstanding used in calculating pro forma loss per
share of common stock are calculated assuming that the estimated 5,911,000
shares of Stamps.com common stock to be issued in the acquisition were
outstanding from the beginning of the periods presented.

The book value per share of Stamps.com common stock was calculated by
dividing stockholders' equity by the number of shares Stamps.com common stock
outstanding, at the end of the period. The number of shares of Stamps.com
common stock outstanding used in calculating pro forma combined book value per
common share are 34,864,807 of Stamps.com common stock outstanding at September
30, 1999 plus 5,911,000 million shares representing the estimated number of
common shares to be issued in the merger. This calculation excludes 1,289,000
shares reserved for option and warrant holders of iShip.com common stock,
800,000 shares reserved for the escrow fund, 5.75 million shares issued in
Stamps.com's December 6, 1999 follow-on offering and 327,500 shares issued to
America Online, Inc. Stamps.com issued these shares to America Online, Inc. in
connection with a three-year marketing and distribution agreement between
Stamps.com and America Online, Inc. executed by the parties in October 1999.

iShip.com pro forma equivalent amounts are calculated by multiplying the
applicable exchange ratio times the number of outstanding shares as of
September 30, 1999. The assumed exchange ratios as of October 22, 1999 were
0.227186 for the iShip.com common stock, 0.237863 for the iShip.com Series A
Preferred Stock and 0.248540 for the iShip.com Series B Preferred Stock.
Stamps.com's date of inception is January 9, 1998; accordingly all information
for the year ended December 31, 1998 with respect to Stamps.com is from the
date of inception to December 31, 1998.

RISK FACTORS

You should carefully consider the risks described below as well as other
information provided to you in this document in deciding how to vote, including
information in the section of this document entitled "--Information Regarding
Forward Looking Statements." The risks and uncertainties described below are
not the only ones facing Stamps.com and iShip.com. Additional risks and
uncertainties not presently known to Stamps.com and iShip.com or that
Stamps.com and iShip.com currently believe are immaterial may also impair
Stamps.com's and iShip.com's respective or combined business operations. If any
of the following risks actually occur, Stamps.com's and iShip.com's businesses,
financial condition or results of operations could be materially adversely
affected, the value of the Stamps.com common stock could decline, and you may
lose all or part of your investment.

Stamps.com and iShip.com face risks associated with the acquisition

The exchange ratio for Stamps.com common stock to be issued in the acquisition
is fixed and will not be adjusted in the event of any change in stock price.

Under the merger agreement, each share of iShip.com capital stock will be
converted into the right to receive shares of Stamps.com common stock. The
number of shares of Stamps.com common stock issuable under the merger agreement
is fixed and will not be adjusted in the event of any decrease in the price of
Stamps.com common stock. If the price of Stamps.com's common stock were to
decrease, iShip.com shareholders would receive securities with a reduced market
value for their iShip.com shares without iShip.com having the right to
renegotiate the transaction based upon the lower market value of the merger
consideration. The price of Stamps.com common stock at the closing of the
acquisition may vary from the price on the date of this document and on the
date of the special meeting. Stamps.com's price may vary because of changes in
the business, operations or prospects of Stamps.com or iShip.com, market
assessments of the likelihood that the acquisition will be completed, the
timing of the completion of the acquisition, the prospects of post-acquisition
operations, regulatory considerations, general market and economic conditions
and other factors. Because the date that the acquisition is completed may be
later than the date of the special meeting and the date of the giving of
consents, the price of Stamps.com common stock on the date of the special
meeting and date of the giving of consents may not be indicative of the price
on the date the acquisition is completed. Stamps.com and iShip.com urge you to
obtain current market quotations of Stamps.com common stock.

The market price of Stamps.com's common stock may be adversely affected by
several factors.

The market price of Stamps.com's common stock could fluctuate significantly
in response to various factors and events, including:

. operating results below market expectations;

The failure to complete the acquisition may result in a decrease in the market
value of Stamps.com's common stock.

The acquisition is subject to a number of contingencies, including approval
by the shareholders of iShip.com and the stockholders of Stamps.com and other
customary closing conditions. As a result, there can be no assurance that the
acquisition will be completed. If the Stamps.com stockholders were to vote
against the proposals at the special meeting or if acquisition is not completed
for any other reason, the trading price of Stamps.com's common stock may fall.

The integration of Stamps.com and iShip.com following the acquisition will
present significant challenges. Stamps.com and iShip.com may not be able to
realize the benefits anticipated from the acquisition.

If the acquisition is completed, Stamps.com will 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 Stamps.com and iShip.com successfully and to manage the
challenges presented by the integration process may result in Stamps.com 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 would occur as a result
of this acquisition may result in disruptions that seriously impair
Stamps.com's business. In particular, if the acquisition is completed,
Stamps.com will have operations in multiple facilities in geographically
distant areas. Stamps.com is not experienced in managing facilities or
operations in geographically distant areas.

The price of the stock of the merged company may be affected by factors
different from those affecting the price of Stamps.com or iShip.com.

Upon completion of the acquisition, holders of iShip.com shares will become
holders of Stamps.com common stock. Stamps.com's business differs from that of
iShip.com, and Stamps.com's operations, as well as the price of Stamps.com
common stock, may be affected by factors different from those affecting a
stand-alone entity. For a discussion of Stamps.com business and other factors
to consider in connection with these businesses, see the discussion below.

Stamps.com faces risks associated with its operations
which will not be reduced by the acquisition

If Stamps.com does not effectively manage the commercial release of
Stamps.com's Internet Postage service, Stamps.com's business will be harmed.

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

The continued commercial roll-out of Stamps.com's service is dependent upon
the service continuing to meet US Postal Service performance specifications and
regulations. Stamps.com is currently conducting a national customer
registration campaign; however, Stamps.com has very limited experience
conducting marketing campaigns, and Stamps.com may fail to generate significant
interest. On the other hand, if Stamps.com experiences extensive interest in
these services, Stamps.com may fail to meet the expectations of customers due
to limited experience in operating these services and the strains this demand
will place on the Stamps.com Web site, network infrastructure and systems.

11
<PAGE>

Stamps.com's ability to obtain and retain customers depends on the
attractiveness of Stamps.com's service to Stamps.com's customers and on
Stamps.com's customer service capabilities. If Stamps.com is unable at any time
during and after the national launch to address customer service issues
adequately or to provide a satisfactory customer experience for current or
potential customers, Stamps.com's business and reputation may be harmed.

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

On June 16, 1999, Pitney Bowes filed a patent infringement lawsuit against
Stamps.com. The suit alleges that Stamps.com is 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. Stamps.com
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 Stamps.com's competitors,
E-Stamp Corporation, alleging infringement of seven Pitney Bowes patents.

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

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 Stamps.com, Stamps.com was in license discussions with
Pitney Bowes. Stamps.com intends to continue these discussions; however,
Stamps.com cannot predict whether these discussions will continue, the outcome
of these discussions or the impact of Pitney Bowes' intellectual property
claims on Stamps.com's business or the Internet postage market. If Pitney Bowes
is unable to prevail in its claims against Stamps.com and if Stamps.com does
not enter into a license relationship with Pitney Bowes, Stamps.com's business
could be impacted severely or fail. In addition, as described above, Pitney
Bowes could obtain monetary and injunctive relief against Stamps.com.

The Internet postage and shipping markets are new and uncertain and
Stamps.com's business may not develop.

The market for Internet postage has not developed, and its development is
subject to substantial uncertainty. Stamps.com cannot assure you that the
Internet postage market will develop. Stamps.com depends on the commercial
acceptance of Stamps.com's Internet Postage service. Stamps.com cannot predict
if Stamps.com's target customers will choose the Internet as a means of
purchasing postage, or if customers will be willing to pay a fee to use
Stamps.com's service, or if potential users will select Stamps.com's system
over Stamps.com's competitors. Stamps.com's target customers often have
alternatives to the US Postal Service and

12
<PAGE>

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 Stamps.com's Internet
Postage service.

In addition, if the acquisition is completed, Stamps.com will enter the
market for online shipping services. There can be no assurance that iShip.com
will succeed as a business. The market for online shipping services is new and
uncertain and may not develop. iShip.com faces many risks frequently
experienced by early stage companies and companies in new, rapidly changing
markets. iShip.com has not released its services commercially. It currently has
no customers and no revenues, and its ability to obtain and retain customers
will depend on the attractiveness of its service to its customers and on its
customer service capabilities. If iShip.com experiences significant system,
customer service, security or other problems once it begins commercial
operation, customers may stop using or refuse to try iShip.com's services. In
addition, shippers may terminate or limit their relationships with iShip.com.
The occurrence of these problems could have a material adverse effect on
iShip.com's and Stamps.com's business, financial condition or results of
operations.

Stamps.com has a history of losses and expect to incur losses in the future,
and Stamps.com may never achieve profitability.

As of September 30, 1999, Stamps.com had not generated any revenues and had
a deficit accumulated during the development stage of $27.3 million.
Stamps.com's lack of revenues can be attributed primarily to the fact that
Stamps.com's Internet Postage service had not been released commercially until
October 22, 1999. Due to the need to establish Stamps.com's brand and service,
Stamps.com expects to incur increasing sales 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,
Stamps.com will need to generate significant revenues to achieve and maintain
profitability.

Stamps.com's ability to generate gross margins generally assumes that if a
market for Internet postage develops, Stamps.com must generate significant
revenues from a large base of active customers. Stamps.com currently charges
Stamps.com's customers a fee to use Stamps.com's Internet Postage service. From
time to time, Stamps.com may offer special promotions to attract new customers.
These promotions involve waiving or discounting convenience fees, discounts on
supplies offered through Stamps.com's online store, or free postage. See
"Business-Stamps.com's Internet Postage Service." However, given the lack of an
established or proven commercial market for Internet postage, Stamps.com cannot
be sure that customers will be receptive to Stamps.com's fee structure. Even if
Stamps.com are able to establish a sizeable base of users, Stamps.com still may
not generate sufficient gross margins to become profitable. In addition,
Stamps.com's ability to generate revenues or achieve profitability could be
adversely affected by special promotions or changes to its pricing plans.

Since inception, iShip.com has not generated any significant revenues and
had an accumulated deficit of $5.9 million as of September 30, 1999. If the
iShip.com acquisition is completed, Stamps.com expects that Stamps.com's 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.

If the iShip.com acquisition is completed, Stamps.com will record a
significant amount of intangibles, the amortization of which will significantly
and adversely affect Stamps.com's operating results. As denoted in the
unaudited pro forma condensed combined balance sheet as of September 30, 1999,
Stamps.com expects these intangibles to equal approximately $288.8 million,
which will be amortized over a four-year period. To the extent Stamps.com does
not generate sufficient cash flow to recover the amount of the investment
recorded, the

13
<PAGE>

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,
Stamps.com's net loss in any given period could be greater than anticipated and
the market price of Stamps.com's stock could decline.

If Stamps.com cannot effectively manage its growth, its ability to provide
services will suffer.

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

Stamps.com may not be able to manage Stamps.com's growth effectively.
Stamps.com's current expansion has and will continue to place a significant
strain on Stamps.com's managerial, operational and financial resources.
Stamps.com's current and planned personnel, systems, procedures and controls
may be inadequate to support Stamps.com's future operations. If Stamps.com is
unable to manage growth effectively or experiences disruptions during
expansion, Stamps.com's business will suffer and Stamps.com's financial
condition and results of operations will be seriously affected.

If Stamps.com is unable to maintain and develop its strategic relationships and
distribution arrangements, Stamps.com's Internet Postage service may not
achieve commercial acceptance.

Stamps.com has established strategic relationships with a number of third
parties. Stamps.com's strategic relationships generally involve the promotion
and distribution of Stamps.com's service through Stamps.com's partners'
products, services and Web sites. Additionally, some of Stamps.com's
relationships provide for the inclusion of Stamps.com's logo or promotional
offers for Stamps.com's service in packaging and marketing materials utilized
by Stamps.com's partners. In return for promoting Stamps.com's service,
Stamps.com's partners may receive revenue-sharing opportunities. In order to
achieve wide distribution of Stamps.com's service, Stamps.com believes
Stamps.com must establish additional strategic relationships to market
Stamps.com's service effectively. Stamps.com has limited experience in
establishing and maintaining strategic relationships and Stamps.com may fail in
Stamps.com's efforts to establish and maintain these relationships.

Stamps.com's current strategic relationships have not yet resulted in
significant revenues, primarily because Stamps.com has only recently
commercially released Stamps.com's Internet Postage service. As a result,
Stamps.com's strategic partners may not view their relationships with
Stamps.com as significant or vital to their businesses and consequently, may
not perform according to Stamps.com's expectations. Stamps.com has little
ability to control the efforts of Stamps.com's strategic partners and, even if
Stamps.com is successful in establishing strategic relationships, these
relationships may not be successful.

In addition, if the acquisition is completed, iShip.com will be dependent on
strategic relationships with Dynamex, eBay, Mail Boxes Etc., UPS, Yellow
Freight Systems and the other major U.S. shipping services. If one or more of
these companies terminates or limits its relationship with iShip.com, its
business could be severely harmed or fail. iShip.com has limited experience in
establishing strategic relationships and it may not be able to develop and
maintain them sufficiently for its business to succeed.

Stamps.com faces risks typical of early stage companies and of new and rapidly
changing markets.

You should consider Stamps.com's 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,
Stamps.com's:

. ability to meet and maintain government specifications for Stamps.com's
service, specifically US Postal Service requirements;

. complete dependence on a service that currently does not have broad
market acceptance;

. need to expand Stamps.com's sales and support organizations;

. ability to establish and promote Stamps.com's brand name;

. ability to expand Stamps.com's operations to meet the commercial demand
for Stamps.com's service;

. development of and reliance on strategic and distribution relationships;

. ability to prevent and respond quickly to service interruptions;

. ability to minimize fraud and other security risks; and

. ability to compete with companies with greater capital resources and
brand awareness.

If Stamps.com does not achieve the brand recognition necessary to succeed in
the Internet postage market, its business will suffer.

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

System and online security failures could harm Stamps.com's business and
operating results.

Stamps.com's services depend on the efficient and uninterrupted operation
of Stamps.com's computer and communications hardware systems. In addition,
Stamps.com must provide a high level of security for the transactions
Stamps.com executes. Stamps.com relies 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
Stamps.com's business and reputation and would likely result in the loss of
customers. Furthermore, if Stamps.com is unable to provide adequate security,
the US Postal Service could prohibit Stamps.com from selling postage over the
Internet.

Stamps.com's 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.
Stamps.com has entered into an Internet hosting agreement with Exodus
Communications, Inc. to maintain Stamps.com's Internet postage servers at
Exodus' data center in Southern California. Stamps.com's operations depend on
Exodus' ability to protect its and Stamps.com's systems in the data center
against damage or interruption. Exodus does not guarantee that Stamps.com's
Internet access will be uninterrupted, error-free or secure. Stamps.com's
servers are also vulnerable to computer viruses, physical, electrical or
electronic break-ins and similar disruptions. Stamps.com has 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

15
<PAGE>

completely impair Stamps.com's ability to generate revenues from its service.
Stamps.com does not presently have a formal disaster recovery plan in effect.
Stamps.com has business interruption insurance; however, Stamps.com cannot be
certain that its coverage will be sufficient to compensate 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 Stamps.com's security measures could misappropriate
confidential information or cause interruptions in its operations. Stamps.com
may be required to expend significant capital and other resources to protect
against potential security breaches or to alleviate problems caused by any
breach. Stamps.com relies on specialized technology 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 Stamps.com uses to protect customer transaction data.
Should someone circumvent Stamps.com's security measures, Stamps.com's
reputation, business, financial condition and results of operations could be
seriously harmed. Security breaches could also expose Stamps.com to a risk of
loss or litigation and possible liability for failing to secure confidential
customer information. As a result, Stamps.com 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 Stamps.com does not expand its product and service offerings, its business
may not grow.

Stamps.com 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 Stamps.com's resources of
revenue and expand Stamps.com's product and service offerings outside the
Internet postage market. With the exception of the merger agreement, Stamps.com
has no commitments or agreements and is not currently engaged in discussions
for any material acquisitions or investments. Stamps.com continues to evaluate
incremental revenue opportunities and derivative applications of Stamps.com's
technology from ticketing, couponing and enterprise mailing systems and plans
to pursue and develop those opportunities with strategic partners and
investors. For instance, Stamps.com announced on November 16, 1999 the
formation of a subsidiary, Encryptix, Inc., to develop secure printing
opportunities in the events, travel and financial services industries. To the
extent Stamps.com pursues new or complementary businesses, Stamps.com may not
be able to expand Stamps.com's service offerings and related operations in a
cost-effective or timely manner. Stamps.com may experience increased costs,
delays and diversions of management's attention when integrating any new
businesses or services. Stamps.com may lose key personnel from Stamps.com's
operations or those of any acquired business. Furthermore, any new business or
service Stamps.com launches that is not favorably received by users could
damage Stamps.com's reputation and brand name in the Internet postage or other
markets that Stamps.com enters. Stamps.com also cannot be certain that it will
generate satisfactory revenues from any expanded services or products to offset
related costs. Any expansion of Stamps.com's operations would also require
significant additional expenses, and these efforts may strain Stamps.com's
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
Stamps.com's business, financial condition and operating results. New issuances
of securities may also have rights, preferences and privileges senior to those
of Stamps.com's common stock.

Fluctuations in Stamps.com's operating results could cause its stock price to
fall.

Prior to its commercial launch on October 22, 1999, Stamps.com had not
generated any revenues from its operations. Accordingly, Stamps.com has a
limited basis upon which to predict future operating results. Stamps.com
expects that its revenues, margins and operating results will fluctuate
significantly due to a variety of factors, many of which are outside of its
control. These factors include:

. the success of the commercial release of Stamps.com's Internet Postage
service;

16
<PAGE>

. the costs of the Pitney Bowes litigation or other intellectual property
claims or litigation;

. the costs of Stamps.com's marketing programs to establish and promote
the Stamps.com brand name;

. the demand for Stamps.com's Internet Postage service;

. Stamps.com's ability to develop and maintain strategic distribution
relationships;

. the number, timing and significance of new products or services
introduced by both Stamps.com and Stamps.com's competitors;

. Stamps.com's ability to develop, market and introduce new and enhanced
services on a timely basis;

. the level of service and price competition;

. the increases in Stamps.com's operating expenses as Stamps.com expands
operations; and

. general economic factors.

Stamps.com's 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 Stamps.com's service. In
addition, a substantial portion of Stamps.com's 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. Stamps.com's
operating expense levels are based, in significant part, on its expectations
of future revenues. If Stamps.com's 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
document, you should not rely on period-to-period comparisons of Stamps.com's
results of operations as an indication of future performance. It is possible
that in some future periods Stamps.com's results of operations will be below
the expectations of public market analysts and investors. In this event, the
market price of Stamps.com's common stock is likely to fall.

Stamps.com relies on a relatively new management team and needs additional
personnel to grow its business.

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

Stamps.com's future success depends on its ability to attract, retain and
motivate highly skilled technical, managerial, marketing and customer service
personnel. Also, if Stamps.com completes the acquisition, Stamps.com's success
will also depend on a successful integration of iShip.com's management with
Stamps.com's senior management team. Stamps.com plans to hire additional
personnel in all areas of its business. Competition for qualified personnel is
intense, particularly in the Internet and high technology industries. As a
result, Stamps.com may be unable to successfully attract, assimilate or retain
qualified personnel. Further, Stamps.com may be unable to retain the employees
Stamps.com currently employs or attract additional technical personnel. The
failure to retain and attract the necessary personnel could seriously harm
Stamps.com's business, financial condition and results of operations.

17
<PAGE>

Third party assertions of violations of their intellectual property rights
could adversely affect Stamps.com's business.

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

A failure to protect Stamps.com's own intellectual property could harm
Stamps.com's competitive position.

Stamps.com relies on a combination of patent, trade secret, copyright and
trademark laws and contractual restrictions to establish and protect
Stamps.com's rights in Stamps.com's products, services, know-how and
information. Stamps.com has three issued US patents and has filed 20 patent
applications in the United States, and one international patent application.
Stamps.com has also applied to register several trademarks and service marks.
Stamps.com plans to apply for other patents in the future. Stamps.com may not
receive patents for any of Stamps.com's patent applications. Even if patents
are issued to Stamps.com, claims issued in these patents may not protect
Stamps.com's technology. In addition, any of Stamps.com's patents might be held
invalid or unenforceable by a court. If Stamps.com's patents fail to protect
Stamps.com's technology, Stamps.com's competitive position could be harmed.
Even if Stamps.com's patents are upheld or are not challenged, third parties
may develop alternative technologies or products without infringing
Stamps.com's patents. Stamps.com generally enters into confidentiality
agreements with Stamps.com's employees, consultants and other third parties to
control and limit access and disclosure of Stamps.com's confidential
information. These contractual arrangements or other steps taken to protect
Stamps.com's 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 Stamps.com's services or intellectual property rights to the same
extent as do the laws of the United States.

In addition, if the acquisition is completed, Stamps.com will face the
additional risk that third parties will challenge iShip.com's intellectual
property rights. The costs of defending against any litigation, including the
diversion of management time and resources, could adversely affect Stamps.com's
business, financial condition and results of operations. Any loss resulting
from intellectual property litigation could severely limit iShip.com's
operations, cause it to pay license fees, or prevent it from doing business.

iShip.com has applied for three patents for its intellectual property and
has applied to register six trademarks and servicemarks. The failure to obtain
these patents, or to obtain patents on future proprietary technology or
trademark protection for its brand name, could have a material adverse effect
on iShip.com's and Stamps.com's business, financial condition and results of
operations.

Stamps.com's growth and operating results could be impaired if Stamps.com is
unable to meet Stamps.com's future capital requirements.

Stamps.com believes that its current cash balances will allow Stamps.com to
fund its operations, including the operation of iShip.com following its
anticipated acquisition, for at least the next 24 months. However, Stamps.com
may require substantial working capital to fund its business and Stamps.com may
need to raise additional capital. Stamps.com cannot be certain that additional
funds will be available on satisfactory terms when needed, if at all.
Stamps.com's future capital needs depend on many factors, including:

. market acceptance of Stamps.com's postage and shipping services;

. the level of promotion and advertising of Stamps.com's postage and
shipping services;

18
<PAGE>

. the level of Stamps.com's development efforts;

. rate of customer acquisition and retention of Stamps.com's postage and
shipping services; and

. changes in technology.

The various elements of Stamps.com's business and growth strategies,
including its plans to support fully the commercial release of its service,
Stamps.com's introduction of new products and services and its investments in
infrastructure will require additional capital. If Stamps.com is unable to
raise additional necessary capital in the future, Stamps.com may be required to
curtail its 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.

Stamps.com could be required to register as an investment company and become
subject to substantial regulation that would interfere with Stamps.com's
ability to conduct Stamps.com's business.

Stamps.com plans to invest the proceeds of the follow-on offering in short-
term instruments consistent with prudent cash management and not primarily for
the purpose of achieving investment returns. This could result in Stamps.com
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 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 Stamps.com does not believe that it is engaged
primarily in the business of investing, reinvesting or trading in securities,
Stamps.com may invest its cash and cash equivalents in government securities to
the extent necessary to avoid having over 40% of its assets consist of
investment securities. Government securities are defined as securities issued
by the U.S. government and federal agencies. These securities generally yield
lower rates of income than other short-term instruments in which Stamps.com has
invested to date. Accordingly, investing substantially all of Stamps.com's cash
and cash equivalents in government securities could result in lower levels of
interest income, which could cause Stamps.com's losses to increase.

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

Stamps.com faces risks associated with Stamps.com's market

If Stamps.com does not respond effectively to technological change,
Stamps.com's service could become obsolete and Stamps.com's business will
suffer.

The development of Stamps.com's service and other technology entails
significant technical and business risks. To remain competitive, Stamps.com
must continue to enhance and improve the responsiveness, functionality and
features of its 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.

19
<PAGE>

The evolving nature of the Internet or the Internet postage market could
render Stamps.com's existing technology and systems obsolete. Stamps.com's
success will depend, in part, on its ability to:

. license or acquire leading technologies useful in Stamps.com's business;

. enhance its existing service;

. develop new services and technology that address the increasingly
sophisticated and varied needs of its 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,
Stamps.com's business. Furthermore, Stamps.com may not be successful in using
new technologies effectively or adapting Stamps.com's technology and systems to
user requirements or emerging industry standards on a timely basis.
Stamps.com's ability to remain technologically competitive may require
substantial expenditures and lead time. If Stamps.com is unable to adapt in a
timely manner to changing market conditions or user requirements, Stamps.com's
business, financial condition and results of operations could be seriously
harmed.

If Stamps.com is unable to compete successfully, particularly against large,
traditional providers of postage products like Pitney Bowes who enter the
online postage market, Stamps.com's revenues and operating results will suffer

The market for Internet postage products and services is new and Stamps.com
expects it to be intensely competitive. At present, E-Stamp has a hardware-
based product commercially available and Pitney Bowes and Neopost Industries
are seeking certification through the Information Based Indicia Program and
have hardware products available for beta testing. All three of these vendors
have also announced that they intend to offer software-based solutions; one of
these, Pitney Bowes, has a software-based product in the final phase of beta
testing as of December 15, 1999. If any of Stamps.com's competitors, including
Pitney Bowes, could provide the same or similar service as Stamps.com,
Stamps.com's operations could be adversely impacted.

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, Stamps.com may not be able to establish or maintain a competitive
position against current or future competitors as they enter the market. Many
of Stamps.com's competitors have longer operating histories, larger customer
bases, greater brand recognition, greater financial, marketing, service,
support, technical, intellectual property and other resources than Stamps.com.
As a result, Stamps.com's 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 Stamps.com. This increased competition may result in reduced operating
margins, loss of market share and a diminished brand. Stamps.com 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 Stamps.com's business.

If the market for Internet postage develops, Stamps.com could face
competitive pressures from new technologies or the expansion of existing
technologies approved for use by the US Postal Service. Stamps.com 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
Stamps.com's competitors or charge Stamps.com a substantial fee for inclusion.
Stamps.com's 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
Stamps.com's service and significantly impact Stamps.com's competitive
position. Stamps.com may be unable to compete successfully against current and
future competitors, and the competitive pressures Stamps.com faces could
seriously harm Stamps.com's business.

20
<PAGE>

If the acquisition is completed, Stamps.com will 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 iShip.com's online service. Alternatively, potential competitors
with greater resources than iShip.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.
iShip.com also faces a significant risk that large shipping companies will
collaborate in the development and operation of an online shipping system that
could make iShip.com's service obsolete.

The success of Stamps.com's business will depend on the continued growth of the
Internet and the acceptance by customers of the Internet as a means for
purchasing postage.

Stamps.com's success depends in part on widespread acceptance and use of the
Internet as a way to purchase postage. This practice is at an early stage of
development, and market acceptance of Internet postage is uncertain. Stamps.com
cannot predict the extent to which customers will be willing to shift their
purchasing habits from traditional to online postage purchasing. To be
successful, Stamps.com's customers must accept and utilize electronic commerce
to satisfy their product needs. Stamps.com's 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 Stamps.com's 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. Stamps.com's 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 Internet
postage;

. 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
Stamps.com's business.

Stamps.com is 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
Stamps.com's service at any time. Any changes in requirements or specifications
for Internet postage could adversely affect Stamps.com's pricing, cost of
revenues, operating results and margins by increasing the cost of providing
Stamps.com's 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
Stamps.com would either absorb or pass through to customers. 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. Stamps.com's business
would suffer dramatically if Stamps.com is unable to adapt Stamps.com's
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 "--If Stamps.com is unable to compete successfully,
particularly against large, traditional providers of postage products like
Pitney Bowes who enter the online postage market, Stamps.com's revenues and
operating results will suffer."

21
<PAGE>

In addition, US Postal Service regulations may require that Stamps.com's
personnel with access to postal information or resources receive security
clearance prior to doing relevant work. Stamps.com may experience delays or
disruptions if Stamps.com's personnel cannot receive necessary security
clearances in a timely manner, if at all. The regulations may limit
Stamps.com's 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.

Stamps.com's operating results could be impaired if Stamps.com or the Internet
become subject to additional government regulation and legal uncertainties.

With the exception of US Postal Service and Department of Commerce
regulations, Stamps.com is 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 Stamps.com's products and services and increase Stamps.com's 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. Stamps.com's
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
Stamps.com's business, or the application of existing laws and regulations to
the Internet and other online services could also harm Stamps.com's business.

Stamps.com offers its Internet Postage service in multiple states and plans
to expand both domestically and internationally. These jurisdictions may claim
that Stamps.com is required to qualify to do business as a foreign corporation
in each state or foreign country. Stamps.com's failure to qualify as a foreign
corporation in a jurisdiction where Stamps.com is required to do so could
subject Stamps.com to taxes and penalties. Other states and foreign countries
may also attempt to regulate Stamps.com's Internet Postage service or prosecute
Stamps.com for violations of their laws. Further, Stamps.com might
unintentionally violate the laws of foreign jurisdictions and those laws may be
modified and new laws may be enacted in the future.

If Stamps.com markets Stamps.com's Internet Postage service internationally,
government regulation could disrupt Stamps.com's operations.

One element of Stamps.com's strategy is to provide service in international
markets. Stamps.com's ability to provide 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,
Stamps.com's 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 Stamps.com's
service in the future, and if Stamps.com obtains the necessary foreign
certification or approvals, Stamps.com would be subject to ongoing regulation
by foreign governments and agencies. To date, efforts to

22
<PAGE>

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 Stamps.com. As a result, Stamps.com cannot predict when, or if,
international markets will become a viable source of revenues for a postage
service similar to Stamps.com.

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

If Stamps.com achieves significant international acceptance of its Internet
Postage service, Stamps.com's 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 Stamps.com's
intellectual property rights and actions by third parties that would restrict
or eliminate Stamps.com's ability to do business in these jurisdictions. If
Stamps.com begins to transact business in foreign currencies, Stamps.com will
become subject to the risks attendant to transacting in foreign currencies,
including the potential adverse effects of exchange rate fluctuations.

The rights of Stamps.com's stockholders and iShip.com shareholders could be
adversely affected because of the concentrated control of Stamps.com's stock.

After the acquisition, Stamps.com's executive officers, directors and 5%
stockholders will control approximately 48.2% of Stamps.com's voting stock.
These stockholders will have significant influence and ability to control most
matters requiring board and stockholder approval, including a significant
corporate transaction like the sale of Stamps.com, a change in control, or the
terms of future equity financings. These stockholders could use their control
in ways that may not be beneficial to you.

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

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

Additional shares held by existing Stamps.com stockholders may be sold into the
public market in the near future, which could cause Stamps.com's stock price to
decline.

Sales of substantial amounts of Stamps.com's common stock in the public
market could adversely affect the prevailing market price of Stamps.com's
common stock. Stamps.com estimates that prior to acquisition of iShip.com,
approximately 11.5 million of Stamps.com's 41.0 million shares of outstanding
common stock were freely tradeable. On December 22, 1999, upon the expiration
of lock-up agreements entered into in connection with Stamps.com's initial
public offering, an additional 2.1 million shares of Stamps.com's outstanding
common stock became available for immediate sale. On February 4, 2000, the
lock-up described below will expire for approximately 6.8 million shares of
Stamps.com's outstanding common stock and, on March 5, 2000, the lock-up
described below will expire for all remaining shares subject to the lock-up.
Prior to these dates, shares subject to lock-up agreements cannot be offered or
sold without the prior written consent of Goldman, Sachs & Co. All of the
shares subject to the lock-up will be 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.

23
<PAGE>

95% of the shares of Stamps.com common stock issued in the acquisition,
executed agreements with the underwriters that they will not offer or sell any
shares of Stamps.com common stock until February 4, 2000 without the prior
written consent of Goldman, Sachs & Co. On February 4, 2000, the lock-up will
expire for 20% of the shares held by these stockholders. On March 5, 2000, the
lock-up will expire for the remaining 80% of the shares held by these
stockholders. Prior to these dates, any shares subject to lock-up agreements
cannot be offered or sold without the prior written consent of Goldman, Sachs &
Co. In addition, the merger agreement provides that Stamps.com is not obligated
to file an S-8 registration statement for options assumed in the acquisition
until the expiration of the 90 day lock-up period for the follow-on offering,
which date is March 5, 2000. Goldman, Sachs & Co. may, in its sole discretion,
at any time and without notice, release all or a portion of the shares
Stamps.com common stock subject to these agreements. Sales of substantial
amounts of Stamps.com common stock in the public market, or the perception that
these sales could occur, could adversely affect the prevailing market price for
Stamps.com's common stock and could impair Stamps.com's ability to raise
capital through a public offering of equity securities.

notifying the Secretary and voting by ballot at the Stamps.com special meeting.
Stamps.com stockholders who attend the Stamps.com special meeting, may vote in
person whether or not they have previously given a proxy, but their presence
without notification to the Secretary of Stamps.com will not revoke a
previously given proxy. In addition, if Stamps.com stockholders beneficially
hold shares of Stamps.com common stock that are not registered in their own
name, they will need additional documentation from the record holder of the
shares to attend and vote personally at the Stamps.com special meeting.

Solicitation of Proxies

Stamps.com will bear the cost of the solicitation of proxies from Stamps.com
stockholders. In addition to solicitation by mail, Stamps.com directors,
officers and employees and its subsidiaries may solicit proxies from
stockholders by telephone or other electronic means or in person. Stamps.com
will cause brokerage houses and other custodians, nominees and fiduciaries to
forward solicitation materials to the beneficial owners of shares of Stamps.com
common stock held of record by these persons. Stamps.com will reimburse
custodians, nominees and fiduciaries for their reasonable out-of-pocket
expenses in doing so. Stamps.com has engaged MacKenzie Partners, Inc. to
represent Stamps.com in connection with the solicitation of proxies at a cost
to Stamps.com of approximately $ plus expenses, and will indemnify
MacKenzie Partners, Inc. against any losses arising out of proxy soliciting
services on Stamps.com's behalf.

THE MERGER

Background of the merger

Stamps.com and iShip.com originally became familiar with one another in May
1999. From May 1999 through July 1999, representatives from the companies had
conversations regarding a potential strategic distribution and marketing
relationship. During that time, the possibility of an acquisition was never
discussed.

On August 3, 1999, representatives of Stamps.com traveled to iShip.com's
offices in Bellevue, Washington to continue discussions with iShip.com's
management about a strategic distribution and marketing relationship. After
returning from the visit, these representatives suggested to John M. Payne,
Chief Executive Officer of Stamps.com, that Stamps.com consider iShip.com as a
strategic acquisition possibility. After discussing the idea with Stamps.com
management, Mr. Payne invited Stephen M. Teglovic, President and Chief
Executive Officer of iShip.com, to Stamps.com's office in Santa Monica,
California on August 12, 1999 to discuss a potential business combination of
the parties. From this time through the execution of a definitive agreement on
October 22, 1999, Mr. Payne provided periodic updates on the proposed
transaction and discussed progress with Stamps.com's non-employee directors.

On August 12, 1999, Mr. Teglovic, Mr. Payne and John W. LaValle,
Stamps.com's Chief Financial Officer, met for dinner to discuss a strategic
relationship, a meeting at which Mr. Payne introduced the possibility of a
business combination between Stamps.com and iShip.com. Mr. Teglovic indicated
that he would consult with management of iShip.com, including its board of
directors, regarding a possible transaction.

On August 18, 1999, Mr. Teglovic telephoned Mr. Payne and indicated that
members of the iShip.com board of directors had authorized him and management
to enter into discussions about a potential business combination. From this
time through the execution of a definitive agreement on October 22, 1999, Mr.
Teglovic provided periodic updates on the proposed transaction and discussed
progress with iShip.com's non-employee directors.

On August 26, 1999, Mr. Teglovic, John Jamerson, Chief Financial Officer of
iShip.com, William Smith, Senior Vice President of Engineering of iShip.com,
and John Dietz, Senior Vice President of Operations of iShip.com, traveled to
Stamps.com's offices for a full day meeting. At this meeting, management of
Stamps.com made presentations about Stamps.com's business and organization. No
discussions or negotiations about the business combination occurred at this
meeting.

On August 31, 1999 and September 1, 1999, members of Stamps.com's
management, including members of the engineering, strategy, legal and finance
groups, traveled to iShip.com's offices to discuss the business, operations and
organization of iShip.com. At these meetings, the companies discussed potential
issues resulting from the integration of the businesses and organizations of
the two companies; however, no other discussions or negotiations regarding the
terms of a transaction occurred at these meetings. From this time until the
execution of a definitive agreement on October 22, 1999, each of Stamps.com and
iShip.com, and their respective legal and accounting advisors, conducted in-
depth business, financial and legal due diligence reviews.

On September 2, 1999, Messrs. Teglovic and Jamerson and Brian Finn, a non-
employee member of the iShip.com board, traveled to Santa Monica for a dinner
meeting with Messrs. Payne, LaValle and other members of Stamps.com's
management team. At this meeting, potential transaction terms and valuation
ranges for iShip.com were discussed initially. However, no specific share
consideration amount or exchange ratio mechanics were discussed at this
meeting. At the conclusion of the meeting, the parties agreed to continue
discussions and negotiations for a business combination.

On September 8, 1999, at a regular meeting of the Stamps.com board, Mr.
Teglovic and Mr. Jamerson made a presentation about the iShip.com business.
Following the presentation, Mr. Teglovic and Mr. Jamerson were excused, and the
Stamps.com board discussed the status of discussions to date and the initial
results of due diligence by the Stamps.com management. At the conclusion of the
discussion, the Stamps.com board

29

authorized Stamps.com's management to continue discussions and negotiations.
In addition, Stamps.com's in-house and outside legal advisors discussed the
board's fiduciary duties in considering a strategic business combination and
strategic alternatives.

From September 8, 1999 through October 22, 1999, Stamps.com and iShip.com,
together with their respective legal, financial and accounting advisors,
conducted due diligence reviews and negotiated the terms of the definitive
merger agreement and other agreements related to the merger, including
employment agreements for each of Messrs. Teglovic, Jamerson, Smith and Dietz.
During this period of time, from September 9 through September 11, Messrs.
Payne and LaValle and Messrs. Teglovic and Jamerson negotiated a fixed share
amount of 8 million shares of Stamps.com common stock for all of iShip.com's
outstanding capital stock, options and warrants. It was also agreed over this
period of time that the aggregate share consideration would be subject to no
adjustments due to fluctuations in the market price of Stamps.com's common
stock.

At board meetings held by Stamps.com on September 22, October 6 and October
13, Stamps.com management presented status on the discussions and negotiations
with iShip.com and board members raised questions, had discussions and made
recommendations about the progress of the transaction. During the same period
of time, iShip.com's management periodically informed its board of directors
about the status of discussions and negotiations.

On October 1, 1999, Stamps.com engaged Thomas Weisel Partners LLC to render
a fairness opinion to the Stamps.com board of directors in connection with the
acquisition of iShip.com. From this date through October 22, 1999, Thomas
Weisel Partners performed financial due diligence and prepared its valuation
analyses of a potential business combination of Stamps.com and iShip.com.

On October 22, 1999, Stamps.com's board of directors met with senior
management and Stamps.com's in-house and outside legal and financial advisors
at a special telephonic meeting to discuss the status of final negotiations
with iShip.com. To begin the meeting, in-house legal counsel presented the
terms of the merger agreement and related agreements. Next, Thomas Weisel
Partners made a presentation regarding its analysis of the proposed
transaction and delivered its oral opinion, subsequently confirmed in writing,
that, as of October 22, 1999, the consideration to be paid to the stockholders
of iShip.com in the merger was fair, from a financial point of view, to
Stamps.com. Following this presentation, Stamps.com's board of directors
engaged in a full discussion of the proposed merger. Stamps.com's board of
directors concluded that the merger agreement was fair to Stamps.com and that
the proposed merger was in the best interests of Stamps.com and its
stockholders. Stamps.com's board of directors unanimously approved the merger
and the merger agreement and related documents and authorized management to
proceed with the execution of the merger documents.

By unanimous written consent dated October 21, 1999, iShip.com's board of
directors, after reviewing the financial and other terms of the merger,
approved the merger and the terms of the merger agreement and authorized
management to proceed with the execution of the transaction documents.

During the late afternoon of October 22, 1999, Stamps.com and iShip.com
entered into the merger agreement; several shareholders of iShip.com entered
into support agreements with Stamps.com; Messrs. Teglovic, Jamerson, Smith and
Dietz executed employment agreements that become effective on the closing of
the merger and the directors and several officers of iShip.com entered into
affiliate agreements.

The merger was jointly announced by Stamps.com and iShip.com on the morning
of October 25, 1999.

Reasons for the merger and Stamps.com's and iShip.com's board of directors
recommendations

Stamps.com's Reasons for the Merger.

The Stamps.com board of directors considered the factors below as reasons
that the merger will be beneficial to Stamps.com and its stockholders:

. the potential of the combined companies to offer a complete one-stop
mailing, shipping and tracking solution over the Internet;

. the strength of iShip.com's management, engineering resources and
understanding of the shipping market;

. iShip.com's established strategic relationships and investors, including
UPS, eBay and Mail Boxes Etc.;

. the complementary nature of the companies' service offerings and
possible synergies from combining Stamps.com and iShip.com;

. the terms and conditions of the merger agreement, including termination
fees and closing conditions;

. the terms and conditions of employment agreements with key management of
iShip.com;

. the expected qualification of the merger as a reorganization under
Section 368(a) of the Internal Revenue Code;

. the transaction being accounted for as a purchase; and

. the opinion dated October 22, 1999 of Thomas Weisel Partners that, as of
that date and on the basis of and subject to the matters described in
the opinion, the consideration to be paid to the shareholders of
iShip.com in this merger was fair, from a financial point of view, to
Stamps.com.

In the course of deliberations, the Stamps.com board of directors also
considered a number of additional factors relevant to the merger, including:

. information relating to the business, assets, management, competitive
position, operating performance and prospects of each of Stamps.com and
iShip.com;

. current industry, market and economic conditions;

. the risks to stockholder value of Stamps.com relying on its Internet
Postage service as a single source of revenues;

. the impact of the merger on Stamps.com's and iShip.com's employees;

. the impact of the merger on Stamps.com's and iShip.com's existing and
potential customers and business relationships; and

. the likelihood that the merger would be completed.

The Stamps.com board of directors also identified and considered a number of
potentially negative factors in its deliberations concerning the merger
including:

. the risk that the operations and back office systems of Stamps.com and
iShip.com might not be successfully integrated;

. the risk that, despite the efforts of Stamps.com and iShip.com after the
acquisition, key personnel might leave Stamps.com and iShip.com;

. the difficulty of managing operations in the different geographic
locations in which Stamps.com and iShip.com operate or are considering
to operate;

. the risk that the potential benefits of the merger might not be fully
realized;

. the risk that competitors may overtake iShip.com in the market for
online shipping and tracking solutions; and

. the risk that other acquisition opportunities may be less dilutive to
existing stockholders.

31
<PAGE>

The Stamps.com board of directors believed that some of these risks were
unlikely to occur, that Stamps.com could avoid or mitigate others, and that
overall, these risks were outweighed by the potential benefits of the merger.

In view of the variety of factors considered in connection with its
evaluation of the merger agreement and the merger and the increase in shares
issuable under the Stamps.com 1999 stock incentive plan, the Stamps.com board
of directors did not find it practicable to and did not quantify or otherwise
assign relative weight to the specific factors considered in reaching its
determination. In addition, individual members of the Stamps.com board of
directors may have given different weight to different factors.

Recommendation of Stamps.com Board of Directors. After careful
consideration, the Stamps.com board of directors, on October 22, 1999,
unanimously determined that the terms of the merger agreement and the merger
and the increase in shares issuable under the Stamps.com 1999 stock incentive
plan are fair to, and in the best interests of, Stamps.com and its stockholders
and has approved the merger agreement and the merger and the increase in shares
issuable under the Stamps.com 1999 stock incentive plan. In reaching its
decision to approve the merger agreement and the merger and to recommend
adoption of the merger agreement and the increase in shares issuable under the
Stamps.com 1999 stock incentive plan by Stamps.com stockholders, the Stamps.com
board of directors consulted with its management team and advisors and
independently considered the proposed merger agreement and the transactions
contemplated by the merger agreement. The Stamps.com board of directors
unanimously recommends that the stockholders of Stamps.com vote "for" the
approval of the merger agreement and "for" the 2.5 million-share increase in
shares issuable under the Stamps.com 1999 stock incentive plan.

iShip.com's Reasons for the Merger.

The iShip.com board of directors considered the factors listed below as
reasons that the merger will be beneficial to iShip.com and its shareholders:

. the potential of the combined companies to offer customers a more
complete set of postage and shipping services;

. Stamps.com's established relationship with the US Postal Service;

. the complementary nature of the companies' service offerings and
possible synergies from combining iShip.com and Stamps.com;

. the terms and conditions of the merger agreement;

. the expected qualification of the merger as a reorganization under
Section 368(a) of the Internal Revenue Code;

. information relating to the business, assets, management, competitive
position, operating performance and prospects of each of Stamps.com and
iShip.com;

. current industry, market and economic conditions;

. the potential benefits to shareholder value of being a company with a
more diversified product line;

. the potential benefits to shareholders of owning shares of a company
that are traded on a national market;

. the impact of the merger on Stamps.com's and iShip.com's customers,
suppliers and employees;

. the likelihood that the merger would be completed;

. the synergistic fit of the senior management teams of both companies;
and

. the synergistic fit of the transaction-based revenue models of both
companies.

In view of the variety of factors considered in connection with its
evaluation of the merger agreement and the merger, the iShip.com board of
directors did not find it practicable to and did not quantify or otherwise
assign relative weight to the specific factors considered in reaching its
determination. In addition, individual members of the iShip.com board of
directors may have given different weight to different factors.

Recommendation of iShip.com Board of Directors.

After careful consideration, the iShip.com board of directors has
unanimously determined that the terms of the merger agreement and the merger
are fair to, and in the best interests of, iShip.com and its shareholders and
has approved the merger agreement and the merger. In reaching its decision to
approve the merger agreement and the merger, the iShip.com board of directors
consulted with its management team and advisors and independently considered
the proposed merger agreement and the transactions contemplated by the merger
agreement. The iShip.com board of directors unanimously recommends that the
shareholders of iShip.com execute and return the written consent soliciting
approval of the merger and the merger agreement.

. with respect to the financial forecasts of iShip.com and Stamps.com
provided to Thomas Weisel Partners by their respective managements, upon

at the time of preparation as to the future financial performances of
iShip.com and Stamps.com and (b) provided a reasonable basis upon which
Thomas Weisel Partners could form its opinion;

board of directors. Some of the summaries of financial analyses performed by
Thomas Weisel Partners include information presented in tabular format. In
order to fully

34
<PAGE>

understand the financial analyses performed by Thomas Weisel Partners, you
should read the tables together with the text of each summary. Considering the
data set forth in the tables without considering the full narrative description
of the financial analyses, including the methodologies and assumptions
underlying the analyses, could create a misleading or incomplete view of the
financial analyses performed by Thomas Weisel Partners.

Comparable Company Analysis. Thomas Weisel Partners compared the valuation
multiples implied by the merger to those of selected publicly-traded Internet
companies. Since there are no directly comparable publicly-traded companies,
Thomas Weisel Partners analyzed companies with similar business models in three
areas: business-to-business, consumer e-commerce and Internet infrastructure.
In so doing, Thomas Weisel Partners did not attach any weight to any category.
Thomas Weisel Partners noted that iShip.com is currently focused on the
consumer segment of the potential customer universe and that the management of
iShip.com believes there are significant opportunities to expand iShip.com's
products and services for use by large and small businesses. The companies
included in each category are:

Business-to-Business Consumer E-Commerce

. bamboo.com . eBay

. E-Stamp . priceline.com

. ImageX.com Internet Infrastructure

. Interactive Pictures . Cyber Source

. NIC . Keynote Systems

. pcOrder.com . Purchase Pro.com

. Private Business . Tumbleweed Communications

For each of these companies, Thomas Weisel Partners calculated the multiples
of enterprise value to estimates of total revenues for the fiscal years 1999
through 2003. For purposes of this analysis, Thomas Weisel Partners defined
enterprise value as equity value plus debt less cash and cash equivalents and
calculated equity value on the basis of closing stock prices on October 22,
1999. Estimated revenues for the comparable companies were derived from equity
research reports published by investment banks. Thomas Weisel Partners then
compared the median multiples of enterprise value to revenue estimates for
fiscal years 1999 through 2001 to the multiples of iShip.com implied by the
consideration to be received in the merger as follows:

<TABLE>

</TABLE>

Thomas Weisel Partners also compared the valuation multiples of Stamp.com in
relation to those of selected publicly-traded logistics and shipping services
company. Thomas Weisel Partners analyzed companies in three areas: logistics
software providers, traditional logistics outsourcing companies and bricks and
mortar shipping services. The companies included in each category are:

Logistics Software Providers Traditional Logistics Outsourcing
Companies

. i2 Technologies
. Air Express International

. Manugistics
. Eagle USA Airfreight

Bricks & Mortar Shipping Services
. Expeditors Int'l of WA

. Pitney Bowes

For each of these companies, Thomas Weisel Partners also calculated the
multiples of enterprise value to estimates of total revenues for the fiscal
years 1999 through 2003. Thomas Weisel Partners then compared the median
multiples of enterprise value to revenue estimates for fiscal years 1999 and
2000 to the multiples of Stamps.com as follows:

Comparable Transactions Analysis. Thomas Weisel Partners reviewed the
following eleven comparable acquisitions of selected Business-to-Business
Internet Companies and other Internet-based service companies that have been
announced since January 1, 1999:

<TABLE>
<CAPTION>
Announcement Date Name of Acquiror Name of Target
----------------- ---------------- --------------
<S> <C> <C>
September 22, 1999 Chemdex Promedix.com
September 13, 1999 National Information Consortium eFed

May 18, 1999 eBay Billpoint
April 29, 1999 Go2Net Virtual Avenue (USAOnline)
April 26, 1999 Amazon.com Accept.com
April 22, 1999 Inktomi Impulse! Buy Network
July 19, 1999 Commerce One Veo Systems
</TABLE>

Revenue information was publicly available for only five of these
transactions: the acquisition of digitalNATION by Verio; the acquisition of
iMall by Excite@Home; the acquisition of Authorize.net by Go2Net; the
acquisition of Virtual Avenue (USAOnline) by Go2Net; and the acquisition of Veo
Systems by Commerce One. For each of these transactions, Thomas Weisel Partners
calculated multiples of the enterprise value of the target company implied by
the transaction to latest twelve month revenues of the target company, as well
as ratios of the target's implied latest twelve month revenue multiple to that
of the acquiror.

Thomas Weisel Partners advised the Stamps.com board of directors that the
two most comparable transactions were the acquisition of iMall by Excite@Home
and the acquisition of Authorize.net by Go2Net. Using the revenue estimate
provided by the management of iShip.com for fiscal year 1999, Thomas Weisel
Partners then compared the implied multiples and ratios of these two
transactions, as well as the median of the multiples and ratios for all five
transactions with the multiples and ratios for iShip.com implied by the
consideration to be received in the merger as follows:

<TABLE>
<CAPTION>
Excite@Home/ Go2Net/ Median for
iMall Authorize.net Transactions iShip.com
------------ ------------- ------------ ---------

Target's latest twelve month
revenue multiple to
Acquiror's latest twelve
month revenue multiple..... 254.6% 8.0% 56.1% 26.6%
</TABLE>

Although Thomas Weisel Partners analyzed the multiples for all Internet
related transactions announced in 1999, Thomas Weisel Partners noted that the
median Enterprise Value to latest twelve month revenues multiple for these
transactions was 15.3, and that this statistic was not as relevant as the
statistics for the transactions summarized in the table above. No company or
transaction used in the comparable company or comparable transactions analyses
is identical to Stamps.com or iShip.com or the merger. Accordingly, an analysis
of the

36
<PAGE>

results of the foregoing is not mathematical; rather, it involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the companies and other factors that could affect the public
trading value of the companies to which Stamps.com, iShip.com and the merger
are being compared.

Comparative Financing Analysis. Based on information provided by the
managements of Stamps.com and iShip.com, Thomas Weisel Partners compared the
increases in equity valuations of Stamps.com and iShip.com implied by the funds
raised in various financing rounds for each company. Thomas Weisel Partners
informed the Stamps.com board of directors that this analysis provides a
framework within which to analyze significant increases in value over
relatively short periods of time.

Discounted Cash Flow Analysis. Using management estimates of iShip.com's
projected free cash flows for fiscal years 2000 through 2004, Thomas Weisel
Partners performed a discounted cash flow analysis. For purposes of this
analysis, free cash flows means earnings before interest and taxes, less taxes,
depreciation and amortization, changes in working capital and capital
expenditures.

Thomas Weisel Partners calculated implied enterprise values and implied
equity values of iShip.com by utilizing discount rates ranging from 20.0% to
30.0% and terminal value multiples of estimated 2004 revenue ranging from 5.0x
to 7.5x. Thomas Weisel Partners arrived at these discount rates based on its
judgment of the weighted average cost of capital of selected publicly traded
companies, and arrived at these terminal multiples based on its review of the
trading characteristics of the common stock of selected publicly traded
companies and the expectation that revenue multiplies will decrease
significantly from their currently high levels as Internet companies experience
high growth. This analysis implied an enterprise value range of $155.7 million
to $359.3 million. Adjusting this range of implied enterprise value by
iShip.com's estimated net debt, Thomas Weisel Partners calculated an implied
equity value range of $165.3 million to $368.9 million. Thomas Weisel Partners
noted that the equity value to be paid by Stamps.com pursuant to the merger was
$305.0 million.

Contribution Analysis. Based on the number of shares outstanding and covered
by options and warrants as of October 22, 1999, following the merger, iShip.com
shareholders and Stamps.com stockholders will own approximately 16.4% and
83.6%, respectively, of the combined company. Using estimates prepared by the
managements of Stamps.com and iShip.com, Thomas Weisel Partners calculated the
estimated contribution by Stamps.com and iShip.com to total revenues and
earnings before interest, taxes, depreciation, and amortization (EBITDA) of the
combined company for the fiscal years 2000 to 2004. In light of the negative
EBITDA projected for fiscal years 2000 and 2001, Thomas Weisel Partners focused
on EBITDA contributions in fiscal years 2002 to 2004.

Thomas Weisel Partners then compared these relative contributions to the
relative contributions of Stamps.com and iShip.com to the combined company's
enterprise value (which Thomas Weisel Partners defined for purposes of this
analysis as equity value plus total debt minus cash) and equity value
(calculated on the basis of closing stock prices on October 22, 1999).

This analysis yielded the following relative contributions:

<TABLE>

Pro Forma Merger Analysis. Thomas Weisel Partners reviewed the pro forma
effects of the merger on the combined company's earnings per share, utilizing
financial forecasts for iShip.com and Stamps.com provided by their respective
managements and not taking into account any merger-related cost savings or
revenue enhancements. This analysis assumed a research and development write-
off of 15% of iShip.com's equity value.

This analysis indicated that the impact of the merger on the combined
company's earnings per share before taking into account goodwill and deferred
compensation would be dilutive in 2000 and 2001, and accretive in 2002, 2003
and 2004. On this basis, the pro forma earnings per share accretion or dilution
is as follows:

<TABLE>
<CAPTION>
Year Per share Accretion/(Dilution)
---- ------------------------------
<S> <C>
2000.......................................... $(0.05)
2001.......................................... $(0.06)
2002.......................................... $ 0.01
2003.......................................... $ 0.19
2004.......................................... $ 0.38

This analysis further indicated that the impact of the merger on the
combined company's earnings per share, taking into account goodwill and
deferred compensation, would be dilutive in all years analyzed. If no write-off
were taken, the dilution would be increased. Assuming the research and
development write-off, the pro forma earnings per share dilution is as follows:

<CAPTION>
Year Per Share Dilution
---- ------------------
<S> <C>
2000.......................................... $(1.22)
2001.......................................... $(1.24)

2003.......................................... $(0.85)
2004.......................................... $(0.64)
</TABLE>

The foregoing description is only a summary of the analyses and examinations
that Thomas Weisel Partners deems material to its opinion. The preparation of a
fairness opinion necessarily is not susceptible to partial analysis or summary
description. Thomas Weisel Partners believes that its analyses and the summary
set forth above must be considered as a whole and that selecting portions of
its analyses and of the factors considered, without considering all analyses
and factors, would create an incomplete view of the process underlying the
analyses set forth in its presentation to us. In addition, Thomas Weisel
Partners may have given various analyses more or less weight than other
analyses, and may have deemed various assumptions more or less probable than
other assumptions. The fact that any specific analysis has been referred to in
the summary above is not meant to indicate that this analysis was given greater
weight than any other analysis. Accordingly, the ranges of valuations resulting
from any particular analysis described above should not be taken to be the view
of Thomas Weisel Partners with respect to the actual value of Stamps.com or
iShip.com.

In performing its analyses, Thomas Weisel Partners made numerous assumptions
with respect to industry performance, general business and economic conditions
and other matters, many of which are beyond the control of Stamps.com and
iShip.com. The analyses performed by Thomas Weisel Partners are not necessarily
indicative of actual values or actual future results, which may be
significantly more or less favorable than those suggested by these analyses.
These analyses were prepared solely as part of the analysis performed by Thomas
Weisel Partners with respect to the financial fairness of the consideration to

analyses do not purport to be appraisals or to reflect the prices at which a

Under its engagement letter dated October 1, 1999, Stamps.com agreed to pay
Thomas Weisel Partners a fee of $250,000 upon the delivery of its opinion and
$150,000 upon the earlier of (a) the consummation of the merger or (b) December
31, 1999. Stamps.com also agreed to reimburse Thomas Weisel Partners for its
reasonable out-of-pocket expenses and to indemnify Thomas Weisel Partners, its
affiliates, and their respective partners, directors, officers, agents,
consultants, employees and controlling persons against specific liabilities,
including liabilities under the federal securities laws.

In the ordinary course of its business, Thomas Weisel Partners actively
trades the equity securities of Stamps.com for its own account and for the

position in these securities. Thomas Weisel Partners also acted as underwriter
in connection with public offerings of Stamps.com's securities, is currently a
co-manager of the follow-on offering and has performed various investment
banking services for Stamps.com.

Accounting treatment and future reporting

The merger of iShip.com and Stamps.com is being accounted for using the
purchase method of accounting under Accounting Principles Board Opinion No. 16.
Under this accounting treatment, as of the effective time of the merger, the
excess of the cost of acquiring iShip.com, including the value of the shares of
Stamps.com common stock offered by this document, over the fair market value of
the assets and liabilities of iShip.com assumed will be recorded as goodwill.
Stamps.com intends to amortize this goodwill on a straight line basis over four
years. iShip.com's results of operations will be included in Stamps.com's
consolidated results of operations following completion of the merger.

Directors and management after the acquisition

Stamps.com's current directors and management are expected to continue to
serve after the acquisition is completed, subject to any resignations or
retirements in the period prior to completion of the acquisition. In addition,
upon the closing of the acquisition two persons nominated by iShip.com will be
elected to the Stamps.com board of directors. Stamps.com has not determined
whether these nominees will take new board seats or whether two incumbent
directors will voluntarily resign to create two vacant seats.

Comparison of Rights of Stamps.com's Stockholders and iShip.com's Shareholders

The rights of iShip.com shareholders are currently governed by the
Washington Business Corporation Act, iShip.com's articles of incorporation,
iShip.com's bylaws and a voting agreement among iShip.com and some of its
shareholders. The rights of Stamps.com stockholders are currently governed by
the General Corporation Law of the State of Delaware, Stamps.com's certificate
of incorporation and Stamps.com's bylaws. Upon completion of the acquisition,
the rights of Stamps.com stockholders and of iShip.com shareholders who become
Stamps.com stockholders as a result of the merger will be governed by the
General Corporation Law of the State of Delaware, Stamps.com's certificate of
incorporation and Stamps.com's bylaws.

The rights of iShip.com shareholders under the Washington Business
Corporation Act, the iShip.com articles of incorporation and the iShip.com
bylaws prior to the merger are substantially the same as the rights of
Stamps.com stockholders under the General Corporation Law of the State of
Delaware, the Stamps.com certificate of incorporation and the Stamps.com

THE MERGER AGREEMENT

The following is a brief summary of the material provisions of the merger
agreement. You are urged to read the annexed merger agreement carefully and in
its entirety.

Terms of the Merger

General

The merger agreement contemplates the merger of a Stamps.com subsidiary into
iShip.com. After the merger, iShip.com will survive as a wholly owned
subsidiary of Stamps.com. The merger will be completed once Stamps.com files
the articles of merger with the Secretary of State of the State of Washington.
Stamps.com believes that this filing will occur at the same time as the closing
under the merger agreement which, unless otherwise agreed, will occur promptly,
and not more than five business days, after the satisfaction or waiver of the
conditions to the merger.

Conversion of Securities

Once the merger is completed, the following will occur:

The merger agreement contains a calculation of the exchange ratio for each
class or series of iShip.com capital stock. In general, Stamps.com will not be
required to issue more than 8 million shares of Stamps.com common stock in
order to complete the acquisition.

The exchange ratios applicable to iShip.com Series A Preferred Stock and
Series B Preferred Stock reflect that in accordance with iShip.com's articles
of incorporation each are entitled to receive their liquidation preference
before sharing in the proceeds of the merger with the common stock.

. The common stock exchange ratio is (a) 8 million minus the liquidation
share number (defined below) divided by (b) the total number of shares
of capital stock of iShip.com outstanding immediately prior to
completion of the acquisition or issuable upon exercise of options or
warrants outstanding immediately prior to the completion of the
acquisition.

. The liquidation share number is (a)(1) the number of shares of Series A
Preferred Stock outstanding immediately prior to the completion of the
acquisition multiplied by $0.375 plus (2) the number of shares of Series
B Preferred Stock outstanding immediately prior to the completion of the
acquisition, including shares issuable upon exercise of the warrant
issued to Mail Boxes Etc., multiplied by $0.75, divided by (b) the
average closing price of the Stamps.com common stock for the thirty
trading days ending on the third trading day prior to completion of the
acquisition.

. The Series A exchange ratio is (a) the common stock exchange ratio plus
(b) $0.375 divided by the average closing price of the Stamps.com common
stock for the thirty trading days ending on the third trading day prior
to completion of the acquisition.

. The Series B exchange ratio is (a) the common stock exchange ratio plus
(b) $0.75 divided by the average closing price of the Stamps.com for
common stock the thirty trading days ending on the third trading day
prior to completion of the acquisition.

Each share of iShip.com capital stock will be converted into a number of
shares of Stamps.com common stock as determined by the exchange ratio for that
class or series of iShip.com capital stock.

As of October 22, 1999, the exchange ratios were as follows:

<TABLE>
<CAPTION>
Exchange
Class or Series of iShip.com Capital Stock Ratio
------------------------------------------ --------
<S> <C>
Common Stock........................................................ 0.227186
Series A Preferred Stock............................................ 0.237863
Series B Preferred Stock............................................ 0.248540
</TABLE>

43
<PAGE>

If Stamps.com or iShip.com issues additional shares or options prior to the
completion of the merger, the exchange ratios will be adjusted to reflect the
additional shares or options. Stamps.com will not issue any fractional shares
of Stamps.com stock in the merger and all fractional shares will be eliminated.

Stock Options and Other Stock Rights

Once Stamps.com and iShip.com complete the merger, Stamps.com will assume
each option or warrant to purchase shares of iShip.com's stock issued under
iShip.com's stock option plan or warrant agreements or otherwise, excluding
warrants that by their terms terminate upon the merger. This means that each
iShip.com stock option and assumed warrant will be converted into an option or
warrant to acquire shares of Stamps.com common stock. The number of shares of
Stamps.com common stock to be subject to the option or assumed warrant will be
the number of shares of iShip.com common stock subject to the option or assumed
warrant multiplied by the applicable exchange ratio and rounded down to the
next whole share of Stamps.com common stock. The exercise price per share of
Stamps.com common stock under the option or assumed warrant will be equal to
the exercise price per share of iShip.com capital stock under the option or
assumed warrant divided by the applicable exchange ratio and rounded up to the
next whole cent.

Exchange of New Stock Certificates

Issuance of New Shares

Once Stamps.com and iShip.com complete the merger, Stamps.com will issue the
certificates representing the shares of Stamps.com common stock in exchange for
the certificates for the shares of iShip.com capital stock. Upon surrender of
iShip.com stock certificates to Stamps.com, the former iShip.com shareholders
will be entitled to receive a certificate representing that number of whole
shares of Stamps.com common stock plus any dividends, which they have the right
to receive under the merger agreement. Their iShip.com stock certificates will
then be canceled.

Dividends and Distributions

No dividends or other distributions declared or made after the merger with
respect to Stamps.com common stock with a record date after the date the merger
is completed will be paid to iShip.com shareholders until they surrender their
iShip.com stock certificates.

Following their surrender of iShip.com share certificates, as a record
holder of certificates representing whole shares of Stamps.com common stock,
they will be paid, without interest:

. the amount of dividends or other distributions with a record date after
the date the merger is completed already paid with respect to whole
shares of Stamps.com common stock; and

. the amount of dividends or other distributions with a record date after
the date the merger is completed but prior to the date of surrender of
the iShip.com stock certificate and a payment date subsequent to the
date of surrender of the iShip.com stock certificate payable with
respect to their whole shares of Stamps.com common stock.

No interest will be paid or accrued on unpaid dividends and distributions,
if any, which may be payable upon surrender of iShip.com stock certificates.

No Transfers After Completion

As soon as the merger is completed, the stock transfer books of iShip.com
will be closed, and there will be no further registration of transfers of
iShip.com stock.

No Liability Under Abandoned Property Laws

The combined company will not be liable to any iShip.com shareholder or
Stamps.com stockholder for any undistributed Stamps.com common stock or cash
from the proceeds of the sale of any excess Stamps.com shares which is
delivered to a public official pursuant to an applicable abandoned property or
similar laws.

44
<PAGE>

Holdback of Shares

The combined company will not pay out 800,000 of Stamps.com shares to the
shareholders of iShip.com at the time the merger is completed. These shares
will be held in escrow by U.S. Stock Transfer Corporation for a period of up to
one year following completion of the acquisition. The combined company may make
a claim against those heldback shares if one or more breaches of any of
iShip.com's representations, warranties or covenants in the merger agreement is
discovered within one year of completion of the acquisition or if the third
party costs incurred by iShip.com in connection with the acquisition exceed
$200,000, except for costs incurred by iShip.com in connection with the
preparation of this document.

Federal Income Tax Considerations

The following discussion constitutes the opinion of each of Brobeck Phleger
and Harrison LLP and Venture Law Group, A Professional Corporation, regarding
the material federal income tax considerations relevant to the exchange of
shares of iShip.com capital stock for shares of Stamps.com common stock as a
result of the merger that are generally applicable to holders of iShip.com
capital stock. This discussion is based on currently existing provisions of the
Internal Revenue Code, existing and proposed treasury regulations thereunder
and current administrative rulings and court decisions, all of which are
subject to change. Any change of that type, which may or may not be
retroactive, could alter the tax consequences described in the following
discussion.

iShip.com shareholders should be aware that this discussion does not deal
with all federal income tax considerations that may be relevant to particular
iShip.com shareholders in light of their particular circumstances, like
shareholders who are dealers in securities, who are subject to the alternative
minimum tax provisions of the Internal Revenue Code, who are foreign persons,
who do not hold their iShip.com stock as capital assets, or who acquired their
shares in connection with stock option or stock purchase plans or in other
compensatory transactions.

In addition, the following discussion does not address the tax consequences
of the merger under foreign, state or local tax laws, the tax consequences of
transactions effectuated prior or subsequent to, or concurrently with, the
merger (whether or not the transactions are undertaken in connection with the
merger), including without limitation any transaction in which shares of
iShip.com stock are acquired or shares of iShip.com stock are disposed of, or
the tax consequences of the assumption by Stamps.com of the iShip.com options
or the tax consequences of any receipt of rights to acquire Stamps.com common
stock. ACCORDINGLY, ISHIP.COM SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING
THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES.

The parties have not and will not request a ruling from the Internal Revenue
Service as to the tax consequences of the merger. However, the merger agreement
provides that the completion of the acquisition is

48
<PAGE>

conditioned on the receipt by Stamps.com of an opinion from its counsel,
Brobeck, Phleger & Harrison LLP, and the receipt by iShip.com of an opinion
from its counsel, Venture Law Group, A Professional Corporation, to the effect
that the merger will constitute a reorganization within the meaning of the
Internal Revenue Code. iShip.com shareholders should be aware that the tax
opinions do not bind the Internal Revenue Service and the Internal Revenue
Service is therefore not precluded from successfully asserting a contrary
opinion.

Assuming the merger qualifies as a reorganization (consistent with the
opinions of counsel that are a condition to the completion of the acquisition),
then, subject to the limitations and qualifications referred to in this
discussion, the merger will generally result in the following federal income
tax consequences to the iShip.com shareholders:

. No gain or loss will be recognized by holders of iShip.com stock solely
upon their receipt of Stamps.com common stock in exchange for iShip.com
stock in the merger (except to the extent of cash received in lieu of a
fractional share of Stamps.com common stock).

. The aggregate tax basis of the Stamps.com common stock received by
iShip.com shareholders in the merger (reduced by any tax basis
attributable to fractional shares deemed to be disposed of) will be the
same as the aggregate tax basis of the iShip.com stock surrendered in
exchange therefor.

. The holding period of the Stamps.com common stock received by each
iShip.com shareholder in the merger will include the period for which
the iShip.com stock surrendered in exchange therefor was considered to
be held, assuming that the iShip.com stock was held as a capital asset
at the time of the merger.

. Cash payments received by holders of iShip.com stock in lieu of a
fractional share will be treated as if the fractional share of
Stamps.com common stock had been issued in the merger and then redeemed
by Stamps.com. An iShip.com stockholder receiving cash will recognize
gain or loss, upon the payment, measured by the difference, if any,
between the amount of cash received and the basis in the fractional
share.

Even though the merger qualifies as a reorganization, an iShip.com
shareholder will recognize gain to the extent shares of Stamps.com common stock
received in the merger are treated as received in exchange for services or
property, other than solely iShip.com stock. All or a portion of any such gain
could be taxable as ordinary income. Gain also will be recognized to the extent
an iShip.com shareholder is treated as receiving directly or indirectly
consideration other than Stamps.com common stock in exchange for iShip.com
stock.

A successful Internal Revenue Service challenge to the reorganization status
of the merger would result in iShip.com shareholders recognizing taxable gain
or loss with respect to each share of stock of iShip.com surrendered equal to
the difference between the shareholder's basis in the share and the fair market
value, as of the time of completion of the merger, of the Stamps.com common
stock received in exchange therefor. In that event, a shareholder's aggregate
basis in the Stamps.com common stock so received would equal its fair market
value, and the stockholder's holding period for the stock would begin the day
after the merger is completed.

APPROVAL OF AMENDMENT TO STAMPS.COM'S 1999
STOCK INCENTIVE PLAN

Stamps.com stockholders are being asked to approve an amendment to the
Stamps.com 1999 Stock Incentive Plan which will increase the number of shares
Stamps.com common stock reserved for issuance under the 1999 plan by an
additional 2,500,000 shares. Stamps.com's board of directors adopted the
amendment on October 22, 1999, subject to stockholder approval at the special
meeting.

The share increase will assure that a sufficient reserve of Stamps.com
common stock remains available under the 1999 plan in order to allow Stamps.com
to continue to utilize equity incentives to attract and retain the services of
key individuals essential to Stamps.com's long-term growth and financial
success. Options to purchase at least 1,500,000 shares of Stamps.com common
will be issued to former employees of iShip.com. Stamps.com relies
significantly on equity incentives in the form of stock option grants in order
to attract and retain key employees and believes that equity incentives are
necessary for Stamps.com to remain competitive in the marketplace for executive
talent and other key employees. Option grants made to newly-hired or continuing
employees will be based on both competitive market conditions and individual
performance.

The following is a summary of the principal features of the 1999 plan, as
most recently amended. Any stockholder who wishes to obtain a copy of the
actual plan document may do so upon written request to the Stamps.com at 3420
Ocean Park Boulevard, Suite 1040, Santa Monica, California 94045, Attention:
Corporate Secretary. The 1999 plan serves as the successor to Stamps.com's 1998
Stock Plan which terminated in connection with the initial public offering of
Stamps.com common stock All outstanding options under the 1998 plan at the time
of termination were transferred to the 1999 plan.

Equity Incentive Programs

The 1999 plan consists of five separate equity incentive programs: (i) the
discretionary option grant program, (ii) the stock issuance program, (iii) the
salary investment option grant program, (iv) the automatic option grant program
for non-employee board members and (v) the director fee option grant program.
The principal features of each program are described below. The compensation
committee of Stamps.com's board of directors will have the exclusive authority
to administer the discretionary option grant and stock issuance programs with
respect to option grants and stock issuances made to Stamps.com's executive
officers and non-employee board members and will also have the authority to
make option grants and stock issuances under those programs to all other
eligible individuals. However, the Stamps.com board of directors may at any
time appoint a secondary committee of one or more board members to have
separate but concurrent authority with Stamps.com's compensation committee to
make option grants and stock issuances under those two programs to individuals
other than Stamps.com's executive officers and non-employee board members. The
compensation committee will also have complete discretion to select the
individuals who are to participate in the salary investment option grant
program, but all grants made to the selected individuals will be governed by
the express terms of that program.

The term plan administrator, as used in this summary, will mean Stamps.com's
compensation committee and any secondary committee, to the extent each of those
entities is acting within the scope of its administrative jurisdiction under
the 1999 plan. However, neither the compensation committee nor any secondary
committee will exercise any administrative discretion under the automatic
option grant or director fee option grant program. All grants under those
programs will be made in strict compliance with the express provisions of those
programs.

Share Reserve

At present, 11,019,551 shares of Stamps.com common stock are reserved for
issuance over the term of the 1999 plan. The share reserve consists of (i) the
7,290,000 shares of Stamps.com common stock initially reserved for issuance
under the 1999 plan (including the shares of Stamps.com common stock subject to
the outstanding options under the Stamps.com predecessor 1998 plan which have
been transferred to the 1999 plan;

51
<PAGE>

plus (ii) 1,229,551 shares added to the share reserve as the result of an
automatic annual reserve increase of three percent as of the last trading day
of December 1999 as provided in the 1999 plan; plus (iii) the 2.5 million-share
increase which is the subject of this proposal. In addition, the share reserve
under the 1999 plan will continue to automatically increase on the first
trading day of each calendar year by an amount equal to three percent of the
total number of shares of Stamps.com common stock outstanding on the last
trading day of the preceding calendar year, but in no event will any annual
increase exceed 1,564,715 shares, subject to adjustment for subsequent stock
splits, stock dividends and similar transactions.

No participant in the 1999 plan may receive option grants, separately
exercisable stock appreciation rights or direct stock issuances for more than
1,125,000 shares of Stamps.com common stock in total per calendar year, subject
to adjustment for subsequent stock splits, stock dividends and similar
transactions. Stockholder approval of this Proposal will also constitute
approval of that 1,125,000-share limitation for purposes of Internal Revenue
Code Section 162(m).

The shares of Stamps.com common stock issuable under the 1999 plan may be
drawn from shares of Stamps.com's authorized but unissued common stock or from
shares of Stamps.com common stock which Stamps.com acquires, including shares
purchased on the open market.

Shares subject to any outstanding options under the 1999 plan (including
options transferred from the predecessor plan) which expire or otherwise
terminate prior to exercise will be available for subsequent issuance. Unvested
shares issued under the 1999 plan which Stamps.com subsequently purchases, at
the option exercise or direct issue price paid per share, pursuant to
Stamps.com's purchase rights under the 1999 plan will be added back to the
number of shares reserved for issuance under the 1999 plan and will accordingly
be available for subsequent issuance. However, any shares subject to stock
appreciation rights exercised under the 1999 plan will not be available for
reissuance.

Eligibility

Officers and employees, non-employee Stamps.com board members and
independent consultants in Stamps.com's service or in the service of
Stamps.com's parent and subsidiaries (whether now existing or subsequently
established) will be eligible to participate in the discretionary option grant
and stock issuance programs. Stamps.com executive officers and other highly
paid employees will also be eligible to participate in the salary investment
option grant program. Participation in the automatic option grant and director
fee option grant programs will be limited to the non-employee members of
Stamps.com board of directors.

Valuation

The fair market value per share of Stamps.com common stock on any relevant
date under the 1999 plan will be deemed to be equal to the closing selling
price per share on that date on the Nasdaq National Market.

Discretionary Option Grant Program

The plan administrator will have complete discretion under the discretionary
option grant program to determine which eligible individuals are to receive
option grants, the time or times when those grants are to be made, the number
of shares subject to each grant, the status of any granted option as either an
incentive stock option or a non-statutory option under the federal tax laws,
the vesting schedule (if any) to be in effect for the option grant and the
maximum term for which any granted option is to remain outstanding.

Each granted option will have an exercise price per share determined by the
plan administrator, but the exercise price will not be less than one hundred
percent of the fair market value of the option shares on the grant date and no
granted option will have a term in excess of ten years. The shares subject to
each option will generally vest in one or more installments over a specified
period of service measured from the grant date. However, one or more options
may be structured so that they will be immediately exercisable for any or all
of the option shares. However, the shares acquired under those options will be
subject to repurchase by Stamps.com, at the exercise price paid per share, if
the optionee ceases service with us prior to vesting in those shares.

52
<PAGE>

Upon cessation of service, the optionee will have a limited period of time
in which to exercise any outstanding option to the extent exercisable for
vested shares. The plan administrator will have complete discretion to extend
the period following the optionee's cessation of service during which his or
her outstanding options may be exercised and/or to accelerate the
exercisability or vesting of the options in whole or in part. This discretion
may be exercised at any time while the options remain outstanding, whether
before or after the optionee's actual cessation of service.

The plan administrator is authorized to issue tandem stock appreciation
rights under the discretionary option grant program which will provide the
holders with the right to surrender their options for an appreciation
distribution from Stamps.com. The amount of the distribution payable by
Stamps.com will be equal to the excess of (a) the fair market value of the
vested shares of Stamps.com common stock subject to the surrendered option over
(b) the aggregate exercise price payable for the shares. This appreciation
distribution may, at the discretion of the plan administrator, be made in cash
or in shares of Stamps.com common stock.

Salary Investment Option Grant Program

Stamps.com's compensation committee will have complete discretion in
implementing the salary investment option grant program for one or more
calendar years and in selecting the executive officers and other eligible
individuals who are to participate in the program for those years. As a
condition to participation, each selected individual must, prior to the start
of the calendar year of participation, file with the compensation committee an
irrevocable authorization directing Stamps.com to reduce his or her base salary
for the upcoming calendar year by a specified dollar amount not less than
$10,000 nor more than $50,000 and to apply that amount to the acquisition of a
special option grant under the program.

Each selected individual who files a timely election will automatically be
granted a non-statutory option on the first trading day in January of the
calendar year for which that salary reduction is to be in effect. Stockholder
approval of the 2.5 million-share increase which is the subject of this
proposal will also constitute pre-approval of each option granted under the
salary investment option grant program on the basis of the increase and the
subsequent exercise of that option in accordance with the terms of the program
summarized below.

The number of shares subject to each option will be determined by dividing
the salary reduction amount by two-thirds of the fair market value per share of
Stamps.com common stock on the grant date, and the exercise price will be equal
to one-third of the fair market value of the option shares on the grant date.
As a result, the total spread on the option shares at the time of grant (the
fair market value of the option shares on the grant date less the aggregate
exercise price payable for those shares) will be equal to the salary reduction
amount. The option will become exercisable in a series of twelve equal monthly
installments upon the optionee's completion of each calendar month of service
in the calendar year for which the salary reduction is in effect and will
become immediately exercisable in all the option shares on an accelerated basis
should Stamps.com experience changes in ownership or control. Each option will
remain exercisable for any vested shares until the earlier of (i) the
expiration of the 10-year option term or (ii) the end of the 3-year period
measured from the date of the optionee's cessation of service.

Stock Issuance Program

Shares may be issued under the stock issuance program for valid
consideration under the Delaware General Corporation Law as the plan
administrator deems appropriate. The shares may also be issued as a bonus for
past services without any cash outlay required of the recipient. Shares of
Stamps.com common stock may also be issued under the program pursuant to share
right awards which entitle the recipients to receive those shares upon the
attainment of designated performance goals. The plan administrator will have
complete discretion under the program to determine which eligible individuals
are to receive stock issuances or share right awards, the time or times when
those issuances or awards are to be made, the number of shares subject to each
issuance or award and the vesting schedule to be in effect for the stock
issuance or share rights award.

53
<PAGE>

The shares issued may be fully and immediately vested upon issuance or may
vest upon the completion of a designated service period or the attainment of
pre-established performance goals. The plan administrator will, however, have
the discretionary authority at any time to accelerate the vesting of any and
all unvested shares outstanding under the stock issuance program.

Outstanding share right awards under the program will automatically
terminate, and no shares of Stamps.com common stock will actually be issued in
satisfaction of those awards, if the performance goals established for the
awards are not attained. The plan administrator, however, will have the
discretionary authority to issue shares of Stamps.com common stock in
satisfaction of one or more outstanding share right awards as to which the
designated performance goals are not attained.

Automatic Option Grant Program

Under the automatic option grant program, eligible non-employee members of
Stamps.com's board of directors will receive a series of option grants over
their period of board service. Each non-employee board member will, at the time
of his or her initial election or appointment to the board, receive an option
grant for 10,000 shares of Stamps.com common stock, as long as the individual
has not previously been in Stamps.com's employ. In addition, on the date of
each annual stockholders meeting, each individual who is to continue to serve
as a non-employee board member will automatically be granted an option to
purchase 2,500 shares of Stamps.com common stock, provided he or she has served
as a non-employee board member for at least six months. There will be no limit
on the number of 2,500-share option grants any one eligible non-employee board
member may receive over his or her period of continued board service, and non-
employee board members who have previously been in Stamps.com's employ will be
eligible to receive one or more annual option grants over their period of board
service.

Stockholder approval of the 2.5 million-share increase which is the subject
of this proposal will also constitute pre-approval of each option granted under
the automatic option grant program on the basis of the increase and the
subsequent exercise of that option in accordance with the terms of the program
summarized below.

Each automatic grant will have an exercise price per share equal to the fair
market value per share of Stamps.com common stock on the grant date and will
have a maximum term of 10 years, subject to earlier termination following the
optionee's cessation of board service. Each automatic option will be
immediately exercisable for all of the option shares; however, any unvested
shares purchased under that option will be subject to repurchase by Stamps.com,
at the exercise price paid per share, should the optionee cease board service
prior to vesting in those shares. The shares subject to each initial 10,000-
share automatic option grant will vest in a series of 36 successive equal
monthly installments upon the optionee's completion of each month of board
service over the 36-month period measured from the grant date. However, the
shares subject to each initial option grant will immediately vest in full upon
changes in control or ownership or upon the optionee's death or disability
while a board member. The shares subject to each annual 2,500-share automatic
grant will be fully vested at the time of the option grant. Following the
optionee's cessation of board service for any reason, each option will remain
exercisable for a 12-month period and may be exercised during that time for any
or all shares in which the optionee is vested at the time of cessation of board
service.

Director Fee Option Grant Program

The plan administrator will have complete discretion in implementing the
director fee option grant program for one or more calendar years. If the
program is implemented, each non-employee board member may elect, prior to the
start of each calendar year, to apply all or any portion of any annual retainer
fee otherwise payable in cash for his or her period of service on the board for
that year to the acquisition of a below-market option grant. The option grant
will be a nonstatutory option and will automatically be made on the first
trading day in January in the calendar year for which one of those elections is
in effect. The option will have a maximum term of 10 years measured from the
grant date and an exercise price per share equal to one-third of the fair
market value of the option shares on the award date. The number of shares
subject to each

54
<PAGE>

option will be determined by dividing the amount of the retainer fee applied to
the acquisition of that option by two-thirds of the fair market value per share
of Stamps.com common stock on the grant date. As a result, the total spread on
the option (the fair market value of the option shares on the grant date less
the aggregate exercise price payable for those shares) will be equal to the
portion of the retainer fee applied to the acquisition of the option.

The option will become exercisable in a series of 12 successive equal
monthly installments upon the optionee's completion of each month of board
service in the calendar year in which the option is granted, subject to full
and immediate acceleration upon changes in control or ownership or upon the
optionee's death or disability while a board member. Each option granted under
the program will remain exercisable for vested shares until the earlier of (i)
the expiration of the ten-year option term or (ii) the expiration of the 3-year
period measured from the date of the optionee's cessation of board service.

Limited Stock Appreciation Rights

Limited stock appreciation rights may be granted under the discretionary
option grant program to one or more of Stamps.com's officers or non-employee
board members as part of their option grants, and each option granted under the
salary investment option grant, automatic option grant and director fee option
grant program will automatically include a limited stock appreciation right.
Upon the successful completion of a hostile tender offer for more than fifty
percent of Stamps.com's outstanding voting securities or a change in a majority
of Stamps.com's board of directors as a result of one or more contested
elections for board membership, each outstanding option with a limited stock
appreciation right may be surrendered to us in return for a cash distribution.
The amount of the distribution payable by us per surrendered option share will
be equal to the excess of (i) the fair market value per share at the time the
option is surrendered or, if greater, the tender offer price paid per share in
the hostile take-over over (ii) the exercise price payable per share under the
option.

Stockholder approval of the 2.5 million share increase which is the subject
of this Proposal will also constitute pre-approval of each limited stock
appreciation right granted under the salary investment option grant, automatic
option grant or director fee option grant program on the basis of the increase
and the subsequent exercise of that right in accordance with the foregoing
terms.

Predecessor Plan

All outstanding options under the predecessor 1998 plan which were
transferred to the 1999 plan will continue to be governed by the terms of the
agreements evidencing those options, and no provision of the 1999 plan will
affect or otherwise modify the rights or obligations of the holders of the
transferred options with respect to their acquisition of Stamps.com common
stock. However, the plan administrator has complete discretion to extend one or
more provisions of the 1999 plan to the transferred options, to the extent
those options do not otherwise contain those provisions.

Stock Awards

The table below shows, as to Stamps.com's Chief Executive Officer,
Stamps.com's four other most highly compensated executive officers (with base
salary and bonus for fiscal year 1998 in excess of $100,000) and the other
individuals and groups indicated, the number of shares of Stamps.com common
stock subject to option grants made under the 1999 plan and the predecessor
1998 plan through December 31, 1999, together with the weighted average
exercise price payable per share. Stamps.com has not made any direct stock
issuances to date under the 1999 plan or the predecessor 1998 plan.

shares remained available for future issuance, assuming stockholder approval of
this Proposal.

New Plan Benefits

No option grants or share issuances have been made to date on the basis of
the share increase which is the subject of this Proposal.

General Provisions

Acceleration. In the event that Stamps.com is acquired by merger or asset
sale, each outstanding option under the discretionary option grant program
which is not to be assumed by the successor corporation will automatically
accelerate in full, and all unvested shares under the discretionary option
grant and stock issuance programs will immediately vest, except to the extent
Stamps.com's repurchase rights with respect to those shares are to be assigned
to the successor corporation. The plan administrator will have complete
discretion to grant one or more options under the discretionary option grant
program which will become fully exercisable for all the option shares in the
event those options are assumed in the acquisition and the optionee's service
is involuntarily terminated within a designated period (not to exceed 18
months) following the acquisition. The vesting of outstanding shares under the
stock issuance program may be accelerated upon similar terms and conditions.
The plan administrator will also have the authority to grant options which will
immediately vest in the event Stamps.com is acquired, whether or not those
options are assumed by the successor corporation.

The plan administrator is also authorized under the discretionary option
grant and stock issuance programs to grant options and to structure repurchase
rights so that the shares subject to those options or repurchase rights will
immediately vest in connection with a change in ownership or control (whether
by successful tender offer for more than 50% of Stamps.com's outstanding voting
stock or by a change in the majority of Stamps.com's board of directors by
reason of one or more contested elections for board membership). That
accelerated vesting may occur either at the time of the change in ownership or
control or upon the involuntary

56
<PAGE>

termination of the individual's service within a designated period (not to
exceed 18 months) following the change in ownership or control.

The plan administrator will have the discretionary authority to extend any
of the acceleration provisions of the 1999 plan to one or more options
transferred from the 1998 plan which do not otherwise contain those provisions.
Currently, the transferred options are structured so that those options will
immediately vest if Stamps.com is acquired by merger or asset sale and
Stamps.com's repurchase rights with respect to the unvested shares subject to
those options are not to be assigned to the successor entity or otherwise
continued in effect. In addition, those options contain additional acceleration
provisions pursuant to which those options will vest upon an involuntary
termination of the optionee's employment within 18 months following an
acquisition in which Stamps.com's repurchase rights with respect to the option
shares continue in effect.

The shares subject to each option under the salary investment option grant,
automatic option grant and director fee option grant program will immediately
vest in the event (i) Stamps.com is acquired by merger or asset sale, (ii) a
tender offer for more than 50% of Stamps.com's outstanding voting stock or
(iii) there is a change in the majority of the board effected through one or
more contested elections for board membership.

The acceleration of vesting in the event of a change in the ownership or
control may be seen as an anti-takeover provision and may have the effect of
discouraging a merger proposal, a takeover attempt or other efforts to gain
control of us.

Stockholder Rights and Option Transferability. No optionee will have any
stockholder rights with respect to the option shares until the optionee has
exercised the option and paid the exercise price for the purchased shares.
Options are not assignable or transferable other than by will or the laws of
inheritance following optionee's death, and during the optionee's lifetime, the
option may only be exercised by the optionee. However, non-statutory options
may be transferred or assigned during optionee's lifetime to one or more
members of the optionee's family or to a trust established for one or more
family members or to one or more other persons, to the extent the transfer is
in connection with the optionee's estate or pursuant to a domestic relations
order.

Changes in Capitalization. In the event any change is made to the
outstanding shares of Stamps.com common stock by reason of any
recapitalization, stock dividend, stock split, combination of shares, exchange
of shares or other change in corporate structure effected without Stamps.com's
receipt of consideration, appropriate adjustments will be made to (i) the
maximum number and/or class of securities issuable under the 1999 plan, (ii)
the maximum number and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under the 1999 plan per calendar year, (iii) the number
and/or class of securities for which grants are subsequently to be made under
the automatic option grant program to new and continuing non-employee board
members, (iv) the number and/or class of securities and the exercise price per
share in effect under each outstanding option, (v) the number and/or class of
securities and the exercise price per share in effect under each outstanding
option transferred from the predecessor 1998 plan to the 1999 plan and (vi) the
maximum number and/or class of securities by which the share reserve under the
1999 plan is to increase automatically each year. These adjustments will be
designed to preclude any dilution or enlargement of benefits under the 1999
plan or the outstanding options thereunder.

Financial Assistance. The plan administrator may institute a loan program to
assist one or more participants in financing the exercise of outstanding
options under the discretionary option grant program or the purchase of shares
under the stock issuance program through full-recourse interest-bearing
promissory notes. However, the maximum amount of financing provided any
participant may not exceed the cash consideration payable for the issued shares
plus all applicable taxes incurred in connection with the acquisition of those
shares.

Special Tax Election. The plan administrator may provide one or more holders
of options or unvested share issuances under the 1999 plan with the right to
have the Company withhold a portion of the shares

<PAGE>

otherwise issuable to these individuals in satisfaction of the withholding
taxes to which these individuals become subject in connection with the exercise
of those options or the vesting of those shares. Alternatively, the plan admin-
istrator may allow these individuals to deliver previously acquired shares of
Stamps.com common stock in payment of the withholding tax liability.

Amendment and Termination. The board may amend or modify the 1999 plan at
any time, subject to any required stockholder approval pursuant to applicable
laws and regulations. Unless sooner terminated by the board, the 1999 plan will
terminate on the earliest of (i) June 30, 2009, (ii) the date on which all
shares available for issuance under the 1999 plan have been issued as fully-
vested shares or (iii) the termination of all outstanding options in connection
with changes in control or ownership.

Federal Income Tax Consequences

Option Grants. Options granted under the 1999 plan may be either incentive
stock options which satisfy the requirements of Section 422 of the Internal
Revenue Code or non-statutory options which are not intended to meet the
requirements. The Federal income tax treatment for the two types of options
differs as follows:

Incentive Options. No taxable income is recognized by the optionee at the
time of the option grant, and no taxable income is generally recognized at the
time the option is exercised. The optionee will, however, recognize taxable
income in the year in which the purchased shares are sold or otherwise made the
subject of a taxable disposition. For Federal tax purposes, dispositions are
divided into two categories: (i) qualifying and (ii) disqualifying. A
qualifying disposition occurs if the sale or other disposition of the shares is
made more than two years after the date the option for those shares is granted
and more than one year after the date the option is exercised for those shares.
If either of these two requirements is not satisfied, then a disqualifying
disposition will result.

Upon a qualifying disposition, the optionee will recognize long-term capital
gain in an amount equal to the excess of (i) the amount realized upon the sale
or other disposition of the purchased shares over (ii) the exercise price paid
for the shares. If there is a disqualifying disposition of the shares, then the
excess of (i) the fair market value of those shares on the exercise date over
(ii) the exercise price paid for the shares will be taxable as ordinary income
to the optionee. Any additional gain or loss recognized upon the disposition
will be recognized as a capital gain or loss by the optionee.

If the optionee makes a disqualifying disposition of the purchased shares,
then Stamps.com will be entitled to an income tax deduction, for the taxable
year in which such disposition occurs, equal to the excess of (i) the fair
market value of the shares on the option exercise date over (ii) the exercise
price paid for the shares. If the optionee makes a qualifying disposition, then
Stamps.com will not be entitled to any income tax deduction.

Non-Statutory Options. No taxable income is recognized by an optionee upon
the grant of a non-statutory option. The optionee will in general recognize
ordinary income, in the year in which the option is exercised, equal to the
excess of the fair market value of the purchased shares on the exercise date
over the exercise price paid for the shares, and the optionee will be required
to satisfy the tax withholding requirements applicable to that income.

If the shares acquired upon exercise of the non-statutory option are
unvested and subject to repurchase by us in the event of the optionee's
termination of service prior to vesting in those shares, then the optionee will
not recognize any taxable income at the time of exercise but will have to
report as ordinary income, as and when Stamps.com's repurchase right lapses, an
amount equal to the excess of (i) the fair market value of the shares on the
date the repurchase right lapses over (ii) the exercise price paid for the
shares. The optionee may, however, elect under Section 83(b) of the Internal
Revenue Code to include as ordinary income in the year of exercise of the
option an amount equal to the excess of (i) the fair market value of the
purchased shares on the exercise date over (ii) the exercise price paid for the
shares. If the Section 83(b) election is made, the optionee will not recognize
any additional income as and when the repurchase right lapses.

58
<PAGE>

Stamps.com will be entitled to an income tax deduction equal to the amount
of ordinary income recognized by the optionee with respect to the exercised
non-statutory option. The deduction will in general be allowed for the taxable
year in which ordinary income is recognized by the optionee.

Stock Appreciation Rights. No taxable income is recognized upon receipt of a
stock appreciation right. The holder will recognize ordinary income, in the
year in which the stock appreciation right is exercised, in an amount equal to
the excess of the fair market value of the underlying shares of Stamps.com
common stock on the exercise date over the base price in effect for the
exercised right, and the holder will be required to satisfy the tax withholding
requirements applicable to such income.

Stamps.com will be entitled to an income tax deduction equal to the amount
of ordinary income recognized by the holder in connection with the exercise of
the stock appreciation right. The deduction will be allowed for the taxable
year in which the ordinary income is recognized.

Direct Stock Issuances. The tax principles applicable to direct stock
issuances under the 1999 plan will be substantially the same as those
summarized above for the exercise of non-statutory option grants.

Deductibility of Executive Compensation. Stamps.com anticipates that any
compensation deemed paid by it in connection with the disqualifying disposition
of incentive stock option shares or the exercise of non-statutory options with
exercise prices equal to the fair market value of the option shares on the
grant date will qualify as performance-based compensation for purposes of Code
Section 162(m) and will not have to be taken into account for purposes of the
$1 million limitation per covered individual on the deductibility of the
compensation paid to Stamps.com's executive officers. Accordingly, all
compensation deemed paid with respect to those options will remain deductible
by Stamps.com without limitation under Code Section 162(m).

Accounting Treatment

Under the current accounting principles in effect for equity incentive
programs like the 1999 plan, the option grants under the discretionary option
grant and automatic option grant programs will not result in any direct charge
to Stamps.com's reported earnings. However, the fair value of those options is
required to be disclosed in the notes to Stamps.com's financial statements, and
Stamps.com must also disclose, in footnotes to Stamps.com's financial
statements, the pro-forma impact those options would have upon Stamps.com's
reported earnings were the fair value of those options at the time of grant
treated as a compensation expense. In addition, the number of outstanding
options may be a factor in determining Stamps.com's earnings per share on a
fully-diluted basis.

On March 31, 1999, the Financial Accounting Standards Board issued an
Exposure Draft of a proposed interpretation of APB Opinion 25, "Accounting for
Stock Issued to Employees." Under the proposed interpretation, option grants
made to non-employee consultants (but not non-employee board members) after
December 15, 1998 will result in a direct charge to Stamps.com's reported
earnings based upon the fair value of the option measured initially as of the
grant date. The charge will accordingly include the appreciation in the value
of the option shares over the period between the grant date of the option (or,
if later, the effective date of the final amendment) and the vesting date of
each installment of the option shares. In addition, if the proposed
interpretation is adopted, any options which are repriced after December 15,
1997 will also trigger a direct charge to Stamps.com's earnings measured by the
appreciation in the value of the underlying shares over the period between the
grant date of the option (or, if later, the effective date of the final
amendment) and the date the option is exercised for those shares.

Should one or more individuals be granted tandem stock appreciation rights
under the 1999 plan, then those rights would result in a compensation expense
to be charged against Stamps.com's reported earnings. Accordingly, at the end
of each fiscal quarter, the amount (if any) by which the fair market value of
the shares of Stamps.com common stock subject to outstanding stock appreciation
rights has increased from the prior quarter-end would be accrued as
compensation expense, to the extent their fair market value is in excess of the
aggregate exercise price in effect for those rights.

Vote Required

The affirmative vote of at least a majority of the shares of Stamps.com
common stock present in person or by proxy at the special meeting and entitled
to vote is required for approval of the amendment to the 1999 plan. Should
stockholder approval not be obtained, then the 2.5 million-share increase to
the share reserve under the 1999 plan will not be implemented, any stock
options granted under the 1999 plan on the basis of that increase will
immediately terminate without ever becoming exercisable for the shares of
Stamps.com common stock subject to those options, and no additional options or
stock issuances will be made on the basis of the proposed share increase. The
1999 plan will, however, continue in effect, and option grants and direct stock
issuances may continue to be made under the 1999 plan until all the shares of
Stamps.com common stock available for issuance under the 1999 plan has been
issued pursuant to option grants and direct stock issuances.

STAMPS.COM'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition and results of
Stamps.com's operations of Stamps.com should be read in conjunction with the
"Selected Financial Data" and Stamps.com's financial statements and the related
notes thereto. This discussion contains forward-looking statements that involve
risks and uncertainties that could cause actual results to differ materially
from historical results or anticipated results including those set forth in
"Risk Factors" and elsewhere in this document.

Overview

Stamps.com Inc. offers a convenient, cost effective and easy-to-use service
for purchasing and printing postage over the Internet. On October 22, 1999,
Stamps.com commercially launched its Internet Postage service. To date,
Stamps.com's 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 its Web site and
associated systems that Stamps.com uses to process customers' orders and
payments. As of December 31, 1999, Stamps.com's customer base consisted of over
85,000 users who had downloaded its software and registered for its service.

Stamps.com currently offers a single service plan to its users. Under its
plan, a user purchases postage at cost and is charged a monthly convenience fee
based upon how much postage he or she uses during the month. The current plan
assesses a convenience fee equal to 10% of the postage printed during a month.
This plan has a monthly minimum fee of $1.99 and a monthly maximum fee of
$19.99. Convenience fees are calculated and charged at the end of a monthly
billing cycle. From time to time, Stamps.com may offer special promotions to
attract new customers. These promotions may involve waiving or discounting
convenience fees, discounts on supplies offered through Stamps.com's online
store, or free postage. Although Stamps.com has established this single pricing
plan, Stamps.com may need to change its pricing plan given the lack of an
established or proven commercial market for Internet postage. In addition,
Stamps.com's ability to generate revenues or achieve profitability could be
adversely affected by special promotions or changes to Stamps.com's pricing
plans. See "Risk Factors--Stamps.com has a history of losses and expects to
incur losses in the future and may never achieve profitability."

Some options and shares granted to Stamps.com's employees from January 9,
1998 (inception) through September 30, 1999 have been considered to be
compensatory. Deferred compensation associated with those options and shares
amounted to $1.25 million for the fiscal year ended December 31, 1998 and $9.51
million for the nine months ended September 30, 1999. Of these amounts,
$167,000 was operations for the nine months ended September 30, 1999 and the
balance of $8.1 million will be amortized over the vesting periods of the
applicable options through the fiscal year ending December 31, 2003.

In October 1999, Stamps.com signed the merger agreement with iShip.com. Upon
completion of the acquisition, up to 8,000,000 shares of Stamps.com common
stock will be issued in exchange for all outstanding iShip.com capital stock,
options and warrants. In addition, if the acquisition is completed, Stamps.com
will record a significant amount of intangibles, the amortization of which will
significantly and adversely affect Stamps.com operating results. As noted in
the unaudited pro forma condensed combined balance sheet as of September 30,
1999, Stamps.com expects these intangibles to equal approximately $288.8
million, which will be amortized over a four-year period. To the extent
Stamps.com does 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, Stamps.com's net loss in any given period could be greater than
anticipated. Stamps.com anticipates that the acquisition will close during the
first quarter of 2000. The acquisition is subject to a number of closing
conditions, including stockholder approval by both iShip.com and Stamps.com and
other customary conditions. As a result, Stamps.com cannot be certain that the
acquisition will be completed.

Results of Operations

Costs and Expenses

Sales and Marketing. Sales and marketing expenses principally consist of
costs associated with Stamps.com's strategic relationships, advertising and
promotional expenditures, compensation and related expenses for personnel
engaged in marketing and business development activities. Sales and marketing
expenses for the nine months ended September 30, 1999 were $10.9 million.
Stamps.com began its first phase of beta testing in August 1998 and therefore
we incurred no sales and marketing expenses during the nine months ended
September 30, 1998. The increase in sales and marketing expenses is principally
due to Stamps.com's marketing campaign and advertising of the launch of
Stamps.com's Internet Postage solution in October 1999, as well as to an
increase in marketing personnel. Stamps.com expects sales and marketing
expenses to increase significantly as it fully rolls out its Internet Postage
service and continues to promote the Stamps.com's brand through new strategic
relationships and marketing campaigns.

Research and Development. Research and development expenses principally
consist of compensation for personnel involved in the development of
Stamps.com's Internet Postage service and expenditures for consulting services
and third-party software. Research and development expenses for the nine months
ended September 30, 1999 were $5.0 million compared to $0.5 million for the
period from January 9, 1998 (inception) to September 30, 1998. The increase is
due to higher personnel and consulting costs and costs associated with the
ongoing development of Stamps.com's Internet Postage service. Stamps.com
believes that significant investments in research and development are required
to remain competitive and expect to incur increasing research and development
expenses.

General and Administrative. General and administrative expenses principally
consist of compensation and related costs for executive and administrative
personnel, facilities fees, fees for legal and other professional services, and
amortization of deferred compensation. General and administrative expenses for
the nine months ended September 30, 1999 were $8.3 million compared to $1.1
million for the period from January 9, 1998 (inception) to September 30, 1998.
Of the $7.2 million increase, $2.5 million is due to amortization of deferred
compensation. The remaining increase is principally due to increased headcount
and the expansion of our facilities related to the growth of Stamps.com's
business, as well as to legal fees related to the Pitney Bowes patent
infringement claim. Stamps.com expects general and administrative expenses to
increase as it grows its business and incur additional costs related to the
Pitney Bowes patent infringement claim.

Interest Income (Expense), Net. Interest income (expense), net consists of
income from our cash and cash equivalents net of interest expense related to
financing Stamps.com's obligations. Interest income (expense), net for the nine
months ended September 30, 1999 was $1.1 million compared to $(2,000) for the
period from January 9, 1998 (inception) to September 30, 1998. This increase is
due to earnings on a higher average cash equivalent balance as a result of
Stamps.com's initial public offering in June 1999.

Liquidity and Capital Resources

As of September 30, 1999, Stamps.com had approximately $61.2 million in cash
and cash equivalents. In June 1999, Stamps.com completed an initial public
offering in which the underwriters sold to the public 5,750,000 shares of
common stock at $11.00 per share. Stamps.com's net proceeds from the offering
were $10.23 per share, or $58.8 million in the aggregate. In December 1999,
Stamps.com raised an additional $355.5 million in a follow-on public offering
in which the underwriters sold to the public 5,750,000 shares of common stock
at $65.00 per share. The net price per share to Stamps.com was $61.83.
Stamps.com regularly invests excess funds in short-term money market funds and
commercial paper and does not engage in hedging or speculative activities.

In October 1999, Stamps.com entered into a distribution and marketing
agreement with AOL that will require aggregate payments by Stamps.com of $56.0
million through April 2002. In addition, under this agreement, AOL purchased
$6.0 million of Stamps.com's common stock in October 1999 and has agreed to
purchase $5.0 million of our common stock concurrent with the closing of the
follow-on offering. AOL also holds a three-year warrant to purchase up to 50%
of the total number of shares it purchases from Stamps.com. See "Description of
Capital Stock-America Online Investment."

65
<PAGE>

In May 1999, Stamps.com entered into a facility lease agreement for its
corporate headquarters with aggregate minimum lease payments of approximately
$4.8 million through May 2004. Stamps.com also entered into an agreement with
Intuit/Quicken.com in May 1999, which requires aggregate payments by Stamps.com
of $3.3 million through 2000.

Net cash used in operating activities was $22.6 million for the nine months
ended September 30, 1999 compared to $1.4 million for the period from January
9, 1998 (inception) to September 30, 1998. 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 $4.8 million for the nine months
ended September 30, 1999 compared to $0.2 million for the period from January
9, 1998 (inception) to September 30, 1998. The increase in net cash used in
investing activities resulted primarily from increased capital expenditures for
computer equipment, purchased software and office equipment.

Net cash provided by financing activities was $85.1 million for the nine
months ended September 30, 1999 compared to $2.3 million for the period from
January 9, 1998 (inception) to September 30, 1998. The increase in net cash
provided by financing activities resulted principally from the initial public
offering in June 1999.

Stamps.com anticipates that its current cash balances will be sufficient to
fund its operations and the operations of iShip.com after the acquisition for
at least the next 24 months. However, Stamps.com may require substantial
working capital to fund its business and may need to raise additional capital.
Stamps.com cannot be certain that additional funds will be available on
satisfactory terms when needed, if at all. See "Risk Factors--Stamps.com's
growth and operating results could be impaired if we are unable to meet our
future capital requirements."

Recently Issued Accounting Pronouncements

The American Institute of Certified Public Accountants issued Statement of
Position No. 98-1, Software for Internal Use," which provides guidance on
accounting for the costs of computer software developed or obtained for
internal use. Currently, Stamps.com capitalizes costs of computer software
obtained for internal use in Stamps.com's Web design and network operations.
These capitalized costs are amortized based on their estimated useful life.
Payroll and related costs are not capitalized, as the amounts are immaterial
and principally relate to maintenance. Purchased or leased computer software
used in research and development activities are accounted for in accordance
with the provisions of Statement of Financial Accounting Standards No. 2.,
"Accounting for Research and Development Costs." Statement of Financial
Accounting Standards No. 2 generally requires all research and development
costs to be charged to expense when incurred if no alternative future uses
exist. Statement of Position No. 98-1 is effective for financial statements for
fiscal years beginning after December 15, 1998. Stamps.com does not expect that
the adoption of Statement of Position No. 98-1 will have a material impact on
Stamps.com's financial statements.

ISHIP.COM'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition and results of
operations of iShip.com should be read in connection with the "Selected
Financial Data of iShip.com" and iShip.com's financial statements and the
related notes thereto. This discussion contains forward-looking statements that
involve risks and uncertainties that could cause actual results to differ
materially from historical results or anticipated results including those set
forth in "Risk Factors" and elsewhere in this document.

Overview

iShip.com was founded in May 1997 and has developed Web-based technology
that is designed to provide a complete one-stop shipping and tracking solution.
iShip.com's tools are designed to help consumers, small businesses and large
corporations price, ship, track and manage shipments over the Internet.
iShip.com's service will enable online users to compare rates and services
among multiple carriers, including Airborne Express, Federal Express, UPS, the
US Postal Service, Yellow Freight and Dynamex, and will also allow users to
print shipping labels directly from desktop printers and manage their shipping
history.

Following iShip.com's incorporation in May 1997, the founders began hiring
additional employees and commenced development of its technology. In September
1997 and April 1998, iShip.com raised $600,000 and $2,770,000, respectively, in
private placements of its Series A Preferred Stock. In April and May 1999 and
August 1999, iShip.com raised $7,400,000 and $200,000, respectively, in private
placements of its Series B Preferred Stock. In May 1998, iShip.com changed its
name from MoveIt! Software, Inc. to iShip.com, Inc.

In April 1999, iShip.com entered into a five-year Manifest System Services
and Co-Branding Agreement with Mail Boxes Etc. to be the exclusive provider of
an Internet-based retail package manifest system to its approximately 3,000
domestic retail centers. In October 1999, a Beta version of this service was
deployed in ten retail centers. In May 1999, iShip.com entered into a five-year
Co-Branding Agreement with eBay to provide fully integrated shipping services
to eBay auction customers. The first phase of this service launched on eBay in
July 1999.

Through September 30, 1999, iShip.com has recognized no revenues, as it has
not yet commenced revenue-based operations. In April 1998, iShip.com began
providing its Internet-based shipping services, including label printing and
package tracking to users. Under its agreement with Mail Boxes Etc., iShip.com
will receive transaction-based license fees from Mail Boxes Etc. and its
participating franchisees. iShip.com currently provides free information
regarding "zip-to-zip" shipping charges to eBay auction buyers and sellers, and
it is contemplated that in the future eBay shippers will pay iShip.com a fee
when they print shipping labels using iShip.com's service. With the current
limited use of its service and the lack of a commercial market for internet
shipping services, iShip.com cannot be sure that these anticipated fees will be
its ultimate pricing approach or that these fees will generate significant
revenues, if at all. As a result, iShip.com cannot predict whether any
contemplated pricing or fee structure will ever generate revenues or profits.

In October 1999, iShip.com entered into the merger agreement, pursuant to
which iShip.com will become a wholly owned subsidiary of Stamps.com and up to
8,000,000 shares of Stamps.com common stock will be issued in exchange for all
outstanding iShip.com capital stock and options and warrants to purchase
iShip.com capital stock. The acquisition is subject to a number of closing
conditions, including approval by the shareholders of iShip.com and the
stockholders of Stamps.com, and other customary conditions. As a result,
iShip.com cannot be certain that the acquisition will be completed.

iShip.com's Results of Operations

Cost of Revenues. Through September 30, 1999, iShip.com did not incur any
costs associated with revenues. iShip.com expects its cost of revenues to
primarily consist of costs associated with operating and

68
<PAGE>

maintaining its data centers, customer and technical support activities,
depreciation of hardware and software utilized in its data centers, credit
card processing fees and Internet connectivity, as well as overhead
allocation.

General and Administrative Expenses. iShip.com's general and administrative
expenses have consisted primarily of salaries and related costs for general
corporate infrastructure, including costs relating to finance, accounting,
facilities and fees for legal and other professional services. iShip.com's
general and administrative expenses for the year ended December 31, 1998 were
$1.0 million. General and administrative expenses increased to $2.2 million
for the nine months ended September 30, 1999 from approximately $758,000 for
the nine months ended September 30, 1998. The increase is principally due to
an increase in personnel, facility costs and professional service fees.

Research and Development Expenses. iShip.com's research and development
expenses have principally consisted of compensation for personnel involved in
the development of its Internet-based shipping services, including its Web
site and related systems, and other costs related to development. Research and
development expenses for the year ended December 31, 1998 were $784,000.
Research and development expenses increased to $1.7 million for the nine
months ended September 30, 1999 from $508,000 for the nine months ended
September 30, 1998. The increase results primarily from costs associated with
iShip.com's increased personnel. iShip.com believes that significant
investments in research and development will be required in the future to
remain competitive and expects to continue to incur significant research and
development expenses.

Sales and Marketing Expenses. Through September 30, 1999, iShip.com
incurred $350,000 in sales and marketing expenses. iShip.com expects that
costs related to its sales and marketing efforts, which to date have not been
significant, will dramatically increase in future periods as iShip.com enters
into the production phase of its business. iShip.com expects its sales and
marketing expenses to consist of expenses related to compensation for sales
and marketing personnel, advertising, creative development, promotions,
commissions and travel. iShip.com expects the majority of these costs to be
directed to programs designed to build brand recognition, attract a customer
base and retain the anticipated customer base.

Product Implementation Expenses. Through September 30, 1999, iShip.com
incurred $74,000 in product implementation expenses. These costs primarily
consist of rent and lease payments on hardware and internet connectivity
charges. iShip.com believes these costs will increase significantly and be
included in cost of revenue once iShip.com enters the production phase of its
business and begins generating revenue.

Liquidity and Capital Resources

Since inception, iShip.com has financed its operations primarily through
the private placement of equity securities, raising $11.0 million through
September 30, 1999. At September 30, 1999, iShip.com had $5.5 million in cash
and cash equivalents, and at September 30, 1998, iShip.com had $163,000 in
cash and cash equivalents and $1.8 million in short term investments.
iShip.com has had significant negative cash flows from operating activities in
each fiscal and quarterly period to date.

In July 1999, iShip.com entered into a new lease agreement relocating its
corporate headquarters. Minimum payments under this lease total approximately
$2.4 million through 2004.

In August 1999, iShip.com entered into a Loan and Security Agreement with
Imperial Bank, which expires in February 2003. The agreement includes $2.5
million for equipment purchases and $450,000 in a committed letter of credit
line. As of September 30, 1999, the outstanding balance under this credit line
was $1.7 million.

Net cash used in operating activities was $2.8 million for the nine months
ended September 30, 1999, $1.0 million for the nine months ended September 30,
1998 and $1.7 million for the year ended December 31, 1998. Cash used in
operating activities consisted primarily of net operating losses and increases
in prepaid expenses, which were partially offset by increases in accrued
expenses and accounts payable.

69
<PAGE>

Net cash used in investing activities was $1.2 million for the nine months
ended September 30, 1999, $1.9 million for the nine months ended September 30,
1998 and $1.1 million for the year ended December 31, 1998. Net cash used in
investing activities in these periods consisted primarily of capital
expenditures for computer equipment, purchased software and office equipment,
as well as the purchase of short-term investments.

Net cash provided by iShip.com's financing activities was $9.2 million for
the nine months ended September 30, 1999, $2.9 million for the nine months
ended September 30, 1998 and $2.9 million for the year ended December 31, 1998.
Net cash provided by financing activities was principally attributable to
private placements of preferred stock and to the proceeds from an equipment
line.

iShip.com believes that its current cash balances will allow it to fund its
operations through at least the end of the first quarter of 2000. However,
iShip.com believes that it will require substantial working capital to fund its
business and will need to raise additional capital. iShip.com cannot be certain
that additional funds will be available on satisfactory terms when needed, if
at all.

Recently Issued Accounting Pronouncements

The American Institute of Certified Public Accountants issued Statement of
Position No. 98-1, "Software for Internal Use," which provides guidance on
accounting for the costs of computer software developed or obtained for
internal use. Currently, iShip.com capitalizes costs of computer software
obtained for internal use in its network operations. These capitalized costs
are amortized based on their estimated useful life. Payroll and related costs
are not capitalized, as the amounts are immaterial and principally relate to
maintenance. Purchased or leased computer software used in research and
development activities are accounted for in accordance with the provisions of
Statement of Financial Accounting Standards No. 2., "Accounting for Research
and Development Costs." Statement of Financial Accounting Standards No. 2
generally requires all research and development costs to be charged to expense
when incurred if no alternative future uses exist. Statement of Position No.
98-1 is effective for financial statements for fiscal years beginning after
December 15, 1998. iShip.com does not expect that the adoption of Statement of
Position No. 98-1 will have a material impact on its financial statements.

Market for iShip.com's Common Equity and Related Shareholder Matters

There is no established public trading market for any class of iShip.com's
capital stock. On August 18, 1999, the most recent date on which iShip.com sold
shares of its capital stock to a third-party investor, iShip.com sold shares of
its Series B Preferred Stock at a price of $0.75 per share.

iShip.com has never declared or paid cash dividends on its common stock and
preferred stock. The payment of dividends will be at the discretion of
iShip.com's board of directors, although iShip.com does not intend to pay a
cash dividend for the foreseeable future.

Quantitative and Qualitative Disclosures About iShip.com's Market Risk

Interest Rate Risk

iShip.com's exposure to market risk for changes in interest rates relates
primarily to iShip.com's investment portfolio and bank credit line. iShip.com
places its investments with high credit quality issuers and, limits the amount
of credit exposure to any one issuer. iShip.com seeks to preserve its invested
funds by limiting default risk, market risk and reinvestment risk. The interest
rate on the bank credit line fluctuates with Imperial Bank's prime rate.

iShip.com mitigates default risk by attempting to invest in high credit
quality securities that it believes to be low risk. iShip.com's portfolio is
limited to marketable securities with active secondary or resale markets to
ensure portfolio liquidity. As of September 30, 1999, iShip.com had $5.5
million of cash and cash equivalents bearing an average annual interest rate of
5.5% and held no short-term or long-term investments.

70
<PAGE>

iShip.com's only significant cash flow exposure is due to rate changes under
the bank credit line. iShip.com primarily enters into debt obligations to
support general corporate purposes including capital expenditures and working
capital needs.

Foreign Currency Risk

At this time, iShip.com does not transact business in foreign currencies and
does not have foreign operations. iShip.com, however, anticipates transacting
business in foreign currencies and establishing foreign operations in future
periods.

Overview of Stamps.com's Industry

Growth of Internet Commerce

The Internet has emerged as a significant global communications medium,
enabling millions of people to share information and conduct business
electronically. A number of factors have contributed to the growth of the
Internet and its commercial use, including:

. the large and growing usage of personal computers in homes and
businesses;

. improvements in network infrastructure and bandwidth;

. easier and cheaper access to the Internet;

. increased awareness of the Internet among consumer and business users;
and

. the rapidly expanding availability of online content and commerce.

According to International Data Corporation, the number of Web users
worldwide will grow from an estimated 142.2 million in 1998 to 502.4 million by
2003. In addition, International Data Corporation estimates that the percentage
of Web users buying goods and services on the Internet will grow from 22% in
December 1998 to 36% in December 2003. International Data Corporation further
estimates that the total value of goods and services purchased over the Web
will increase from approximately $50.4 billion in 1998 to approximately $1.3
trillion in 2003. Business-to-business commerce is expected to contribute
significantly to the future growth of Internet commerce. For example,
International Data Corporation estimates that business-to-consumer commerce on
the Internet will grow from approximately $14.9 billion in 1998 to
approximately $177.7 billion in 2003 while business-to-business commerce on the
Internet will grow from approximately $35.5 billion in 1998 to approximately
$1.1 trillion in 2003.

Rapid Growth in Internet Usage by Small Businesses

The small office/home office and small business markets represent a large
and growing customer segment. According to International Data Corporation,
there were a combined 44.7 million small businesses and home offices in the
United States in 1998, a number which International Data Corporation forecasts
will grow to 57.6 million by 2002. For 1998, International Data Corporation
reported that small businesses with less than 100 employees numbered 7.4
million of which 77% had fewer than 10 employees. In addition, home offices
numbered 37.3 million, of which 22.2 million were income producing home
offices, and the remainder were home offices used for corporate after hours
work or telecommuting.

Stamps.com believes that small businesses increasingly will rely on the
functionality and pervasiveness of the Internet to reach and serve a large and
global group of end users. The reduced cost of selling and marketing on the
Internet, the ability to build and serve a large base of customers
electronically and the potential for personalized low-cost customer interaction
provide significant economic advantages. These overall benefits, combined with
accessibility, have led to adoption of the Internet by small businesses and
home offices. According to International Data Corporation, there will be 30.2
million US home offices accessing the Internet by 2002. According to Cyber
Dialogue/FindSVP's 1999 US Small Business Internet Survey, 43% of businesses
with fewer than 100 employees are estimated to be online in 1999. Of those
small businesses that are currently online, 63% are already ordering products
online and are spending an average of $171 monthly on postage. The Cyber
Dialogue/FindSVP survey also found that 64% of online small businesses have
employees who are online multiple times a day. This increased use of the
Internet has resulted in small businesses becoming significant participants in
the electronic commerce market. International Data Corporation estimates that
small businesses accounted for $4.4 billion of electronic commerce in 1998 and
will account for approximately $100.4 billion of electronic commerce activity
in 2002.

Traditional Postage Industry and the Emergence of the Internet Postage

The traditional postage industry is large and growing. According to the US
Postal Service Annual Report, the total postage market was $58.0 billion in
1998, of which $38.9 billion was represented by first class, priority and
express mail with the remainder consisting of other classes of mail including
periodicals, bulk and international. In addition, the US Postal Service
processed over 197 billion pieces of mail in 1998. Despite the growth in the
use of e-mail, the total US postage market increased by 3.1% in 1998 from 1997.

Despite this consistent growth in the postage market, the US Postal Service
has experienced:

. strong competition from overnight delivery services;

. loss of revenue due to postal fraud; and

. continued public demand for more convenient access to US Postal Service
products and services.

Recently, the General Accounting Office, in a report issued on October 21,
1999, stated that competition from alternatives like online invoicing, bill
payment and financial transactions could lead to substantial declines in the
U.S. Postal Service's First Class Mail volume in the next decade. Specifically,
the report projects that First Class Mail will grow at an average annual rate
of 1.8% in fiscal years 1999 to 2002 and then decline at an average annual rate
of 2.5% in fiscal years 2003 to 2008. In addition, the Postal Service also
forecasts Standard A mail, which is primarily advertising mail and includes
letters, flats and parcels that are not sent by first-class mail or priority
mail, to increase by an average annual rate of 5.3% in fiscal years 1999
through 2002 and to increase by an average annual rate of 3.3% in fiscal years
2003 through 2008.

In response to these challenges, in 1995 the US Postal Service announced a
program for its first new postage method since the approval of the postage
meter in 1920. The Information Based Indicia Program is a ten-stage
certification process for commercial release of Information Based Indicia
products, or electronic postage, that can be purchased over the Internet and
printed from a computer using ordinary laser or inkjet printers. Indicia are a
new type of US Postal Service approved postage marks similar to stamps or
metered postage. Information Based Indicia, which are essentially digital
stamps, consist of a two dimensional bar code

73
<PAGE>

containing an encrypted digital signature that make each indicium unique.
Through the Information Based Indicia Program, the US Postal Service is seeking
to enhance user convenience with a new access channel for postage that allows
users to print postage from their personal computer 24 hours a day, seven days
a week. The Information Based Indicia Program is intended to achieve the US
Postal Service's security and revenue objectives by incorporating technological
security features in each unique digitally-signed indicium and a secure postage
accounting vault to provide greater revenue security. All Internet postage
products, including any subsequent enhancements or additional implementation of
a product, must complete US Postal Service testing and evaluation to ensure
operational reliability, financial integrity and security to become certified
for commercial distribution. Overall, the Information Based Indicia Program
aims to provide improved, accurate mail processing and increased productivity,
a result which is intended to:

. reduce US Postal Service costs and postal fraud;

. increase US Postal Service to underserved markets, including the rapidly
growing small office/home office and other small business markets; and

. improve the US Postal Service's competitive position against overnight
delivery services.

The emergence of Internet postage though the US Postal Service's Information
Based Indicia Program has created an attractive channel for the sale of
postage, particularly to small office/home office and other small businesses.
According to a 1997 US Postal Service survey of over 1,600 home offices, 98% of
the respondents would likely use commercial software products to print postage
directly from their computers, 88% of the respondents did not use a postage
meter and 43% of the respondents purchased over $50 of postage per month.
Stamps.com believes that small businesses consider cost-effective mail
generation, elimination of trips to the post office and the production of
professional-looking mail as key components of an effective mailing system.
Internet postage satisfies these requirements by providing 24 hours a day,
seven day a week access to metered mail from the desktop. Furthermore, when
considering the total cost of a traditional postage meter, including lease fees
for both the meter and scale, meter resetting fees and special ink cartridges,
small businesses pay a significant premium in addition to their normal postage
expenditures for leasing a postage meter. Leasing a postage meter also requires
space for additional hardware and the purchase of specialized materials and
supplies. Meanwhile, small businesses that find leasing a postage meter
uneconomical are still faced with the inconvenience of travelling to the post
office, ATM or other locations to purchase stamps.

Stamps.com's Strategy

Our objective is to be the leading provider of convenient, cost effective
and easy to use software-based Internet postage services. To achieve this
objective, Stamps.com's strategy includes the following key elements:

Enhance Brand Name. Stamps.com intends to increase its brand recognition
through a variety of marketing and promotional techniques, including the
prominent display of the Stamps.com logo on all pieces of mail generated
through Stamps.com's service and co-marketing and co-branding agreements with
strategic partners. Stamps.com also intends to promote its brand by conducting
an ongoing public relations campaign and developing affiliations and affinity
programs. Stamps.com believes that building the brand awareness of Stamps.com's
Internet Postage service is critical to attracting and expanding Stamps.com's
customer base.

Leverage Strategic Partnerships. Stamps.com intends to develop and utilize
strategic partnerships to gain access to large numbers of potential users,
cooperatively market products and services, cross-sell additional services and
gain entry into new markets. As of December 1999, Stamps.com has entered into
strategic partnerships with AOL, IBM, Microsoft, Office Depot, Quicken.com and
3M, among others. Stamps.com believes that it can further utilize its strategic
partnerships to enhance its brand name and grow its customer base.

Exploit First-to-Market Advantages. On October 22, 1999, Stamps.com
commercially launched its Internet Postage service. It is currently the only
software-based Internet Postage service approved for commercial release by the
US Postal Service. Stamps.com has a significant first-to-market advantage as a

75
<PAGE>

software-based solution in the Internet postage market. Stamps.com believes its
potential market position will be enhanced by significant barriers to entry,
including:

. a ten-step US Postal Service certification process, including a three-
phase beta testing requirement;

. a software-based Internet Postage service that does not require
additional hardware;

. significant up-front time and investment by potential competitors in
technology and technical infrastructure;

. strong brand awareness for its software-based Internet Postage service;
and

. inconvenience of switching from one metered postage provider to another.

Rapidly Grow Customer Base. Stamps.com intends to broaden Stamps.com's
customer base by capitalizing on its brand, strategic partnerships and first-
to-market advantages. Stamps.com believes that its service can achieve rapid
distribution because there is no investment in hardware beyond a PC and
printer, and users can obtain Stamps.com's software for free. Stamps.com is
primarily targeting the small office/home office and small business markets as
well as various segments of the corporate and consumer markets.

Leverage Software-Based Solution and Technology. Stamps.com intends to
utilize Stamps.com's scaleable, e-commerce platform to enhance Stamps.com's
service offerings and expand the benefits of secure online transactions.
Stamps.com believes that it has an inherent advantage relative to its
competitors in the Internet postage industry because its solution does not
require the use of additional hardware. Stamps.com believes Stamps.com can
achieve rapid distribution of its services as users download or install
Stamps.com's free software. Additionally, Stamps.com provides increased
flexibility and scalability over competing solutions because transactions are
processed through Stamps.com's secure server while competing hardware solutions
require each user to utilize a CD-ROM and peripheral hardware device for each
PC that is engaged in a postage transaction. Stamps.com will continue to invest
in and enhance its technology in order to increase efficiency, reliability and
bandwidth, and to expand its services and reduce its costs.

Pursue Additional Revenue Opportunities. Stamps.com intends to utilize its
brand, electronic commerce capabilities, infrastructure and user base to
develop additional revenue opportunities. Stamps.com will consider the
following opportunities:

. Document Fulfillment Market. Stamps.com will consider investing in
technology that will allow Stamps.com to extend Stamps.com's core
Internet postage technology to print authenticated documents, including
airline, movie and concert tickets, from laser or inkjet printers. For
instance, Stamps.com announced in November 1999 the formation of a
subsidiary, Encryptix, to develop secure printing opportunities in the
events, travel and financial services industries.

. Sale of Postage Related Products. Stamps.com intends to use its Web site
to offer mailing-related products, including labels and envelopes,
mechanical scales, PC-enabled digital scales and label printers.
Stamps.com also intends to offer package insurance to Stamps.com's
customers through third-party insurance companies.

. International Internet Postage Market. Stamps.com believes that if
foreign postal authorities accept the use of Internet postage there will
be significant opportunities in international markets for its Internet
postage service. Stamps.com intends to focus on those regions where
there is a critical mass of Internet use and a large current postage
market with a need for highly secure, transaction-oriented Internet
services.

Stamps.com's Internet Postage Service

existing PC, printer and Internet set-up are sufficient. As a complement to
Stamps.com's Internet Postage service, customers may purchase scales, printers,
mailing supplies and other general office supplies from Stamps.com's online
store.

Accessing Stamps.com's service is simple. A user obtains Stamps.com's free
software either via a download from the Internet or through an install from a
CD-ROM. After installing the software and completing a brief registration
process, the user can connect via the Internet to Stamps.com's secure server
and purchase postage electronically 24 hours a day, seven days a week.
Stamps.com acts as an ongoing intermediary between the US Postal Service and
users by offering users the ability to purchase postage through Stamps.com's
secure server. Stamps.com uses sophisticated technologies which meet strict US
government security standards and Stamps.com's service incorporates the US
Postal Service mandated address verification features to enhance the efficiency
of mail processing and delivery. Finally, Stamps.com's Postage Server is
designed to interact with word processing, contact and address management,
accounting and corporate applications to provide postage for letters, invoices,
statements, checks and other business documents automatically.

Stamps.com assess its customers a convenience fee to access its Internet
Postage service. Stamps.com currently offers a single service plan to its
users. The plan is month-to-month and a user can cancel service at any time.
Under Stamps.com's plan, a customer purchases postage at cost and is charged a
monthly convenience fee based on how much postage he or she uses during the
month. The current plan assesses a convenience fee equal to 10% of the postage
printed during the month. There is a monthly minimum fee of $1.99 and a maximum
monthly fee of $19.99. Convenience fees are calculated and charged at the end
of a monthly billing cycle. From time to time, Stamps.com may offer special
promotions to attract new customers. These promotions may involve waiving or
discounting convenience fees, discounts on supplies offered through
Stamps.com's online store, or free postage. Although Stamps.com has established
the single pricing plan, Stamps.com may need to change pricing plans or
promotions given the lack of an established or proven commercial market for
Internet postage. In addition, Stamps.com's ability to generate revenues or
achieve profitability could be adversely affected by special promotions or
changes in its pricing plans. See "Risk Factors -- Stamps.com has a history of
losses and expects to incur losses in the future and may never achieve
profitability."

The US Postal Service Certification Process

All Internet postage products must complete extensive US Postal Service
testing and evaluation in the areas of operational reliability, financial
integrity and security to become certified for commercial distribution. Each
additional implementation of a particular product or function requires
additional evaluation and approval by the US Postal Service prior to commercial
delivery.

The US Postal Service certification process for Internet postage is a
standardized, ten-stage process concluding with commercial release. Each stage
requires US Postal Service review and authorization to proceed to the next
stage of the certification process. The US Postal Service has no published
timeline or estimated time to complete each of the ten stages of the program.

The ten stages of the US Postal Service certification process are defined at
the US Postal Service Web site and are as follows:

1. Letter of Intent 7. Product Submission/Testing
2. Non-Disclosure Agreements 8. Product Infrastructure Testing
3. Concept of Operations 9. Three Phase Beta Test Approval
(Limited Distribution)

4. Software and Documentation Requirements
5. Provider Infrastructure Plan 10. Vendor Product Approval (Full
Distribution)

6. US Postal Service Address Matching System

Stamps.com's Certification Progress and Commercial Release

In March 1997, Stamps.com submitted its letter of intent to join the
Information Based Indicia Program. From March 1997 through August 1998,
Stamps.com progressed through the first eight stages of the US Postal Service
certification process. On August 24, 1998, the US Postal Service announced that
Stamps.com was approved for beta testing and Stamps.com's Internet postage
service became the first software-based postage solution approved by the US
Postal Service for market testing. Between August 24, 1998 and August 9, 1999,
Stamps.com successfully completed the three-phase beta testing required by the
US Postal Service's certification process. On August 9, 1999, Stamps.com became
the first software-based Internet postage solution approved for commercial
release by the US Postal Service. On October 22, 1999, Stamps.com initiated the
commercial roll-out of its service. As of December 31, 1999, Stamps.com's
customer base consisted of 87,360 users who had downloaded its software and
registered for its service.

Stamps.com's Strategic Distribution Partners

Stamps.com's objective is to achieve significant market penetration through
relationships with strategic partners in each of the four following categories:

. Web portals, content sites and Internet service providers, including
AOL;

. independent software vendors, including Quicken.com and Microsoft;

. PC, printer and other equipment manufacturers, including IBM; and

. office/postal supplies vendors, including 3M and Office Depot.

Stamps.com believes it will benefit from these relationships by achieving
positive brand association and a cost effective means of customer acquisition.
Stamps.com believes its partners can utilize their relationships with
Stamps.com to derive additional revenue opportunities, including revenue-
sharing arrangements, and provide more value-added services to their customers.
Stamps.com's current strategic partners include:

3M Deluxe Financial Services
iGo.com Mindspring Seiko
Instruments
Allbizdepot.com
Dymo/CoStar Inc.com MySoftware
AllBusiness.com Galileo International Interland Office.com USOPNet.com
America Online HotOffice Lotus Westvaco

IBM Microsoft Quicken.com

Stamps.com's Marketing and Sales

Stamps.com intends to establish a strong brand name by allocating
significant resources to its marketing and distribution efforts. Stamps.com
distributes postage printing software through its Web site and distribution
partners. In addition, Stamps.com will rely on traditional media and several
other channels to achieve rapid distribution of its services, including:

Web Sites. Stamps.com intends to work with high traffic Web sites including
portals, commerce and content sites, and other high visibility Internet sites.
This channel will provide the opportunity for users to download Stamps.com's
software and access Stamps.com's Internet postage service.

Affiliate Programs. Stamps.com intends to utilize the traffic and customers
of other online sites by offering revenue-sharing opportunities to affiliates
that provide a link on their Web site to download Stamps.com's Internet Postage
software and access other related services. Stamps.com can leverage its
affiliates abilities to offer new, value-added services and increase repeat
visits to their site.

78
<PAGE>

Preloaded/Bundled Hardware and Services. Stamps.com intends to take
advantage of relationships with vendors of hardware products, including
computers, printers and label makers, and with Internet service providers to
offer Stamps.com's software to buyers of their products. Stamps.com leverage
its resellers' ability to promote new features on commodity, non-differentiated
products and services.

Embedded Software. Stamps.com intends to seek further partnerships with
software publishing companies. Software packages that would benefit from
Stamps.com's current services would include word processing, contact and
address management, accounting, billing and retail software.

Postal Supplies. Stamps.com will target companies in the postal supplies
industry, including manufacturers of envelopes, labels, checks, forms, digital
scales and postage meters.

Financial Services. Stamps.com will seek distribution and co-branding
opportunities with banks and brokerages by incorporating Stamps.com's Internet
Postage service into online banking and investing offered by financial service
providers.

Direct Sales. Stamps.com will target specific large industries or vertical
markets where distributed use of the mail is prevalent, including insurance,
travel and hospitality, financial services, law firms or other businesses where
branch offices or agent organizational structures are common. Stamps.com
believes that significant benefits in the form of usability, convenience and
cost savings to large corporate users may result from integrating Stamps.com's
Internet Postage service into the everyday work flow.

Customer Retention Programs. Stamps.com believes it can increase customer
retention by offering co-branded affinity marketing programs, including
frequent flyer miles based on postage and other related expenditures. Further,
Stamps.com intends to create strong customer loyalty by offering discounts to
Stamps.com's online store that are tied to customer postage volume.

Stamps.com's Competition

The market for Internet postage products and services is new and Stamps.com
expects it to be intensely competitive. The US Postal Service approved
Stamps.com's software-based Internet postage service and E-Stamp Corporation's
hardware-based Internet postage service for commercial release on August 9,
1999. At present, two other Internet postage vendors have hardware and software
products available for beta testing.

The following is a summary of Stamps.com's competitors in the Information
Based Indicia Program, including the status of each competitor's product in the
US Postal Service certification process:

E-Stamp Corporation. E-Stamp is a developer and marketer of a hardware-based
solution enabling users to generate postage transactions from their existing
personal computers and printers. E-Stamp was the first company to gain US
Postal Service approval for market testing of a hardware storage device
identified as the Postal Security Device. The US Postal Service approved E-
Stamp's PC Postal Security Device product for commercial release on August 9,
1999.

Neopost Industrie. Neopost is a large French postage company with a small
percentage of US market share in the traditional postage meter industry.
Similar to E-Stamp, Neopost has developed an online postage product that
requires a special purpose hardware device, and announced their approval for
Phase I beta testing in September 1998. On March 29, 1999, Neopost announced
that their software-based postage product was approved for Phase I beta
testing. Both of these products entered Phase II beta testing on December 7,
1999. Finally, Neopost has commercially available a specialty metering device
that can be attached to a user's PC and allows a user to download postage to
the specialty device from the Internet. This specialty metering device is not
regulated by the Information Based Indicia Program because it does not allow
for the printing of postage from standard inkjet or laser printers.

79
<PAGE>

Pitney Bowes, Inc. Pitney Bowes is the current market leader in the
traditional postage meter business and according to its most recent annual
report had approximately $4.2 billion in revenues in 1998. Pitney Bowes has
developed a product similar to E-Stamp which requires the use of a specialized
hardware device for postage transactions. In addition, Pitney Bowes has
developed a software-based postage product. On December 15, 1999, Pitney Bowes
announced that it had received approval from the US Postal Service to proceed
to the third and final phase of beta testing for both its hardware and software
products. See "Risk Factors--Success by Pitney Bowes in its suit against
Stamps.com alleging patent infringement could prevent us from offering our
Internet Postage service and severely harm our business or cause it to fail."

In addition to competing with Internet postage vendors for market share of
Internet postage sales, Stamps.com will also compete with traditional postage
methods including stamps and metered mail. While Stamps.com believes its
Internet Postage service provides benefits over traditional postage methods,
Stamps.com cannot be certain that Internet postage will be adopted by postage
consumers on a commercial scale, if at all. These customers may continue to use
traditional means to purchase postage, including purchasing postage from their
local post office. Any failure by Stamps.com or other Internet postage vendors
to displace traditional postage methods would seriously impact Stamps.com's
ability to compete with providers of traditional postage.

Stamps.com may also face competition from hardware-based products. Although,
Stamps.com believes its software-based solution is easier to use than hardware-
based products, hardware-based products have some advantages. For example,
Stamps.com's service requires a user to connect to the Internet each time the
user prints postage, while the hardware-based solution allows users to download
postage onto a storage device that is connected to the user's computer. If
users of hardware-based products do not transition to software-based solution,
Stamps.com could face continuing competition from this market.

Overall, Stamps.com may not be able to maintain a competitive position
against current or future competitors as they enter the markets in which
Stamps.com competes. This is particularly true with respect to competitors with
greater financial, marketing, service, support, technical, intellectual
property and other resources than us. Stamps.com's failure to maintain a
competitive position within the market could seriously harm Stamps.com's
business, financial condition and results of operations. Stamps.com believes
that the principal competitive factors in its market include:

. US Postal Service product certification;

. successful commercial release;

. brand recognition;

. convenience;

. ease of use;

. price;

. accountability;

. security;

. compatibility;

. accuracy; and

. integration.

For further discussion of the competitive risks and factors to be
considering in making an investment in Stamps.com common stock, see "Risk
Factors--Success by Pitney Bowes in its suit against Stamps.com alleging patent
infringement could prevent Stamps.com from offering its Internet Postage
service and severely harm Stamps.com's business or cause it to fail" and "--If
Stamps.com is unable to compete successfully, particularly against large,
traditional providers of postage products like Pitney Bowes who enter the
online postage market, Stamps.com's revenues and operating results will
suffer."

Stamps.com's Technology

Stamps.com's service is comprised of the following key components:

System Architecture. Stamps.com's servers are located in a high-security,
off-site data center and operate with internally developed security software.
These servers create the information-based indicia. These servers also process
postage purchases using secure technology that meets US Postal Service security
requirements.

Stamps.com's service currently supports Windows-based client applications,
which Stamps.com believes is easier for customers to use and provides the power
and flexibility necessary to support a variety of label and envelope options
and a wide range of printers. In addition, Stamps.com's application employs an
internally developed user authentication mechanism for additional security.

Transaction Processing. Stamps.com's transaction processing servers are a
combination of secure, commercially available technologies that are designed to
provide secure and reliable transactions. Stamps.com's system implements
hardware to exceed the highest government standard for security and data
integrity currently in effect. The performance and scalability of Stamps.com's
Internet Postage system allows a wide range of users to process postage
transactions through Stamps.com's Web site.

Database Processing. Stamps.com's database servers are designed to
complement industry-leading database technologies and can be built to scale
incrementally as needed.

Client Module. Stamps.com's system utilizes a secure client module for
authentication, which has been designed to minimize transmission time over the
Internet. The client module is designed to be the building block for Internet
postage capabilities that are accessible from popular software applications.
Stamps.com's client module will be used by its postage application as well as
add-ins for popular word processing applications and third party mailing and
business systems.

Stamps.com's Intellectual Property

Stamps.com relies on a combination of patent, trade secret, copyright and
trademark laws and contractual restrictions to establish and protect
intellectual property rights in products, services, know-how and information.
Stamps.com has three issued US patents and has filed 20 patent applications in
the United States, and one international patent application. Stamps.com has
also applied for several trademarks and service marks. Stamps.com plans to
apply for other patents in the future.

Despite efforts to protect Stamps.com's intellectual property rights,
Stamps.com faces substantial uncertainty regarding the impact that other
parties' intellectual property positions will have on the Internet postage
market. In particular, Pitney Bowes has sent formal comments to the US Postal
Service asserting that intellectual property of Pitney Bowes related to postage
metering and systems would be infringed by products meeting the requirements of
the Information Based Indicia Program's specifications. Furthermore, in June
1999, Pitney Bowes filed two separate lawsuits in the United States District
Court for the District of Delaware against both us and E-Stamp alleging
infringement of Pitney Bowes patents. For a discussion of claims by Pitney
Bowes and risks associated with intellectual property, please refer to "Risk
Factors--Success by Pitney Bowes in its suit against Stamps.com alleging patent
infringement could prevent Stamps.com from offering its Internet Postage
service and severely harm Stamps.com's business or cause it to fail" and "--
Legal Proceedings."

Stamps.com's Employees

As of September 30, 1999, Stamps.com had 158 full time employees, of which
48 were employed in research and development, 54 were employed in network
operations, 32 were employed in sales and marketing, and 24 were employed in
administrative positions. None of Stamps.com's employees are represented by a
labor union, and Stamps.com considers Stamps.com's employee relations to be
good. Stamps.com intends to expand significantly Stamps.com's employee base in
2000. See "Risk Factors--Stamps.com relies on a relatively new management team
and need additional personnel to grow Stamps.com's business."

<PAGE>

Stamps.com's Properties

Our corporate headquarters is located in a 47,000 square foot facility in
Santa Monica, California under a lease expiring on May 31, 2004. Stamps.com
also has a 5,000 square foot satellite research and development site in Irvine,
California under a lease expiring in February 2001. If the iShip.com
acquisition is completed, Stamps.com will also have a lease for approximately
21,000 square feet in Bellevue, Washington, expiring in August 2004. Stamps.com
believes that its current facilities and other facilities that will be
available to us will be adequate to accommodate its needs for the foreseeable
future.

Legal Proceedings

On June 16, 1999, Pitney Bowes sued Stamps.com for alleged patent
infringement in the United States District Court for the District of Delaware.
The suit alleges that Stamps.com is 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. Stamps.com filed
an answer to 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 Stamps.com's competitors,
E-Stamp Corporation, alleging infringement of seven Pitney Bowes patents.

The outcome of the litigation that Pitney Bowes has brought against
Stamps.com is uncertain. Therefore, Stamps.com 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 Stamps.com alleging patent
infringement could prevent Stamps.com from offering its Internet Postage
service and severely harm Stamps.com's business or cause it to fail."

On December 29, 1999, three individual plaintiffs sued Stamps.com for
alleged breach of oral contract, quantum meruit, fraud and negligent
representation in the California Superior Court for the County of Los Angeles.
The suit alleges that the plaintiffs were due cash consideration for securing a
board member and investors for Stamps.com. The suit seeks compensatory damages,
punitive and exemplary damages and attorneys' fees and costs incurred. The
outcome of this litigation is uncertain and Stamps.com can give no assurance
that the plaintiffs will not prevail.

Stamps.com is not currently involved in any other material legal
proceedings, nor has Stamps.com been involved in any other material proceedings
that has had or may have a significant effect on Stamps.com's financial
position. Stamps.com is not aware of any other material legal proceedings
pending against us.

ISHIP.COM

This discussion contains forward looking statements that involve risks and
uncertainties that could cause actual results to differ materially from
historical results or anticipated results including those set forth under "Risk
Factors" and elsewhere in this document.

iShip.com was founded in May 1997 and has developed Web-based technology
that provides a complete, one-stop shipping and tracking solution. iShip.com's
tools are designed to help consumers, small businesses and large corporations
price, ship, track and manage shipments over the internet. iShip.com's service

Traditional Shipping Industry and the Emergence of Internet-Based Shipping

By 2003, Forrester Research predicts that the number of residential packages
shipped from online sales will top 2.1 billion per year. Forrester Research
also projects that total residential package deliveries will grow from 2.98
million packages per day in 1999 to 6.53 million packages per day in 2003.
International Data Corporation predicts a sharp rise in the number of Internet
users making purchases, from 31 million in 1998 to more than 183 million in
2003. With the growth in e-commerce activities, there is also increasing demand
for package shipments relating to online commerce transactions in the business-
to-consumer and business-to-business markets. iShip.com believes that
technology is and will continue to play an increasingly important role in
creating efficiencies in package shipments. In addition, iShip.com believes
that a major goal of package carriers is to capture shipping information
electronically in order to reduce costs, increase accuracy, and speed tracking
and billing. The internet provides an ideal medium through which this
information can be distributed and managed.

The iShip.com Solution

iShip.com offers a convenient and easy to use Web-based technology that
enables users to choose and purchase shipping services, print labels, and track
shipments directly from their personal computers. iShip.com's core technology
provides a platform for serving consumers, small businesses and large corporate
enterprises. iShip.com's multi-carrier shipping solution provides simplified
functionality for consumers, a broader feature set for the small business, and
extensive management tools for the large corporate enterprise user.

Benefits to the User. iShip.com's internet shipping service is designed to
be convenient, cost effective and easy to use, and to provide the following
benefits to the user:

. accurate, complete, reliable shipping and tracking information;

. multi-carrier service and rate comparison;

. shipping labels printed from laser jet printers;

. address book and shipping history;

. e-mail based notification and tracking; and

. administration and reporting features.

iShip.com's Strategy

iShip.com's objective is to be the leading Web-based shipping solution. To
achieve this objective, iShip.com's strategy includes the following key
elements:

Enhance the iShip.com Brand. iShip.com intends to increase its brand
recognition through a variety of marketing and promotional techniques,
including co-marketing and co-branding agreements with strategic

83
<PAGE>

partners, affiliate programs, and ongoing public relations campaigns. iShip.com
believes that building brand awareness of its services and technology is
critical to attracting and expanding its customer base.

Leverage Strategic Partnerships and Relationships. iShip.com intends to
develop and utilize strategic partnerships to gain access to large numbers of
potential users, cooperatively market products and services, cross-sell
additional services and gain entry into new markets. iShip.com has entered into
strategic partnerships with Mail Boxes Etc., eBay and Yellow Freight, among
others, and UPS is a principal shareholder of iShip.com. iShip.com intends to
utilize its strategic partnerships and relationships to enhance its brand and
grow its customer base.

Leverage iShip.com's Scaleable Technology. iShip.com intends to utilize its
scaleable technology platform to enhance and broaden its service offerings
across multiple market segments. iShip.com's scaleable multi-carrier shipping
solution provides simplified functionality for consumers, a broader feature set
for the small business, and extensive management tools for the large corporate
enterprise user.

Pursue Additional Revenue Opportunities. Once iShip.com has developed a
customer base, iShip.com intends to utilize its brand, electronic commerce
capabilities, infrastructure and user base to develop additional revenue
opportunities in areas like management report generation, data backup, archival
and retrieval, and shipment analysis.

iShip.com's Internet-Based Shipping Service

iShip.com has developed Web-based technology that is designed to provide
online customers a complete one-stop multi-carrier shipping and tracking
solution. iShip.com's tools are designed to help consumers, small businesses
and large corporations price, ship, track and manage shipments over the
Internet. iShip.com's core service is designed to enable shippers to:

. select the optimal shipping solution every time they ship a package;

. print shipping labels from their desktop laser jet printers or high-
speed thermal printers;

. track packages, including in-bound packages;

. send and receive e-mail notifications of the status of shipped packages;

. maintain a shipping log and history of packages shipped;

. generate reports to help them better manage their shipping process; and

. provide shipping data to the package carriers' back-end host systems.

iShip.com's Strategic Partners

iShip.com's objective is to achieve significant market penetration through
relationships with strategic partners in various markets, including: consumer-
to-consumer online auction communities, business-to-business online auction
communities, small business online communities, major online retailers, online
commerce service providers and Web-based enterprise applications. As the
Internet is increasingly an application environment, vendors of traditional
application categories like Enterprise Resource Planning, Customer Relationship
Management and Warehouse Management Software are redesigning their services for
the Web, which may create additional opportunities for iShip.com to enter into
relationships to offer vendors a shipping solution.

iShip.com believes that its strategic partnerships and relationships will
provide positive brand association, a cost-effective means of customer
acquisition, additional revenue opportunities and an enhanced offering of
products and services for its customers.

In April 1999, iShip.com entered into a five-year Manifest System Services
and Co-Branding Agreement with Mail Boxes Etc. Under the terms of this
agreement, iShip.com is the exclusive provider of an

84
<PAGE>

Internet-based manifest system for the approximately 3,000 domestic Mail Boxes
Etc. franchisees to process packages for shipment, and iShip.com will provide
Mail Boxes Etc. with extensive Internet-based management and reporting tools.
As of December 31, 1999, approximately 1,400 Mail Boxes Etc. franchisees have
entered into subscription agreements to use this system. Under the agreement,
iShip.com will receive transaction-based payments from Mail Boxes Etc. and its
franchisees. Upon expiration of the initial five-year term, Mail Boxes Etc. has
the option to extend the agreement for additional two-year terms subject to
mutually agreed pricing terms.

In May 1999, iShip.com entered into a five-year Co-Branding Agreement with
eBay to provide integrated package shipping services to eBay auction sellers
and buyers. It is contemplated that in the future eBay shippers will pay
iShip.com a fee when they print shipping labels using iShip.com's service.

In October 1999, iShip.com entered into a two-year Shipping Interface
Agreement with Yellow Freight Systems, Inc. to feature Yellow Freights'
shipping rates and other related information on the Web sites of iShip.com and
its partners. iShip.com will receive transaction fees for each Yellow Freight
shipment originated by iShip.com or through its services.

iShip.com's Sales and Marketing

iShip.com intends to market and sell its services to consumers, small
businesses and corporate enterprises through different channels. iShip.com
intends to distribute its shipping and tracking tools and utilities widely
across the Internet through affiliate and other marketing programs. iShip.com
intends to market and sell its small business shipping as a subscription-based
service accessed through its Web site and the Web site of its distribution
partners. The corporate enterprise service will be marketed and sold through a
direct sales force to shipping professionals within large organizations, as a
service they can provide to all employees throughout the enterprise.

Web Sites. iShip.com intends to work with high traffic and high visibility
Web sites, including portals, commerce and content sites, to provide Internet
users with greater access to its Internet-based shipping service.

Affiliate Programs. iShip.com intends to utilize the traffic and customers
of other Web sites by offering revenue-sharing opportunities to affiliates that
provide iShip.com's shipping and tracking tools and services, often through co-
branded pages or sites. Affiliates can capitalize on the ability to offer new
value-added services to attract and retain users.

Direct Sales. Using a direct sales force, iShip.com intends to target large
corporate enterprises that require improved management of their package
shipping activities. iShip.com believes that integration of its service into
the everyday work flow of large corporate users will result in significant
benefits in the form of improved control, greater cost containment, more
accurate reporting, and enhanced data warehousing and management.

iShip.com's Competition

The market for Internet-based shipping services is new and iShip.com expects
it to be intensely competitive. At present, iShip.com's principal competitors
fall into two general categories: traditional package carriers and providers of
online shipping information.

The major domestic package carriers include UPS, FDX Corporation (FedEx and
RPS), the US Postal Service and Airborne Express. Additionally, there are
hundreds of local and regional domestic package carriers. Most of the major
carriers offer various services to their customers via Internet technology.
These carriers also have deep and longstanding ties to their customers, and
their customers may not utilize iShip.com's technology.

85
<PAGE>

Other companies which compete with iShip.com's Internet-based shipping
services include the following:

Pitney Bowes, through an affiliated Web site located at www.valueship.com,
provides multi-carrier package pricing and tracking features similar to
iShip.com's services. Additionally, Pitney Bowes has a long relationship with
numerous businesses to whom they provide multi-carrier shipping software.

Virtan, Inc. operates a Web site with a URL of www.smartship.com that
provides multi-carrier pricing and tracking features similar to iShip.com's
services. Additionally, this Web site provides users the ability to process
their shipments with a package carrier, a service iShip.com currently offers
only on a test basis.

BITS, Inc. operates a Web site with a URL of www.intershipper.net that is
competitive with iShip.com. The BITS, Inc. site provides a rate feature
similar to iShip.com's pricing feature where pricing is compared across
multiple carriers and service offerings. Additionally, both the BITS, Inc. and
iShip.com provide a package tracking service and a feature to integrate their
services into affiliate web sites.

Express Shipping Centers, Inc. operates a Web site located at
www.packagenet.com that provides a single-carrier Web-based shipping service.

Recently, a Web site with a URL of www.goship.com announced that they
intend to build a Web site that provides multi-carrier pricing and tracking
features substantially similar to services offered by iShip.com.

In addition, other companies provide traditional and Internet-based multi-
carrier shipping and tracking software but do not presently operate publicly
accessible Web sites which provide shipping services, including TanData
Corporation and Kewill Systems plc, the parent company of Aristo and Tracer
Research.

iShip.com may not be able to maintain a competitive position against
current or future competitors as they enter the markets in which iShip.com
competes. This is particularly true with respect to competitors that have
greater financial, marketing, service, support, technical, intellectual
property and other resources than iShip.com. iShip.com's failure to maintain a
competitive position within the market could seriously harm its business,
financial condition and results of operations. iShip.com believes that the
principal competitive factors in its market include:

. brand recognition;

. functionality and feature sets;

. convenience and ease of use;

. cost effectiveness;

. reliability and accuracy; and

. scaleability.

iShip.com's Technology

iShip.com's service is comprised of the following key components:

System Architecture. iShip.com's service is offered to customers via
Internet browsers, and its server environment utilizes Microsoft Windows NT.
The iShip.com service is designed on a three-tier architecture comprised of
customer, transactional and database technology layers.

Transaction Processing. iShip.com's transaction processing servers are a
combination of secure commercially available technologies that are designed to
provide secure and reliable transactions. The performance and scaleability of
iShip.com's Internet shipping system allows a wide range of users to process
shipping transactions through its Web site.

Database Processing. iShip.com's database servers are designed and built
with industry leading database technologies and hardware and can be scaled
incrementally as needed. Its production servers are located in a high security
off-site data center, and its development and test data centers are located at
its corporate headquarters, allowing iShip.com to test releases in stages.

iShip.com's Intellectual Property

iShip.com relies on a combination of patent, trade secret, copyright and
trademark laws and contractual restrictions to establish and protect its
intellectual property rights in products, services, know-how and information.
iShip.com has filed a US patent application and has applied to register two
trademarks and service marks. In addition, iShip.com presently intends to apply
for other patents and trademarks in the future.

Despite efforts to protect its intellectual property rights, iShip.com faces
substantial uncertainty regarding the impact that other parties' intellectual
property positions will have on the Internet-based shipping market.

iShip.com's Employees

As of December 31, 1999, iShip.com had 92 full time employees, 51 of which
are involved in the development of its Internet-based technology. None of its
employees are represented by a labor union, and it considers its employee
relations to be good.

iShip.com's Properties

iShip's corporate headquarters are located in Bellevue, Washington in a
facility consisting of approximately 21,000 square feet that is leased through
July 31, 2004. iShip.com believes that its current facilities and other
facilities that will be available to it will be adequate to accommodate its
needs for the foreseeable future.

serving staggered three-year terms. As a result, approximately one-third of
Stamps.com's board of directors will be elected each year. These provisions,
together with the provision of Stamps.com's amended and restated certificate of
incorporation, allow the Stamps.com board of directors to fill vacancies of or
increase the size of Stamps.com's board of directors, and may deter a
stockholder from removing incumbent directors and filling those vacancies with
its own nominees in order to gain control of the board.

Stamps.com's Board Committees

Stamps.com board of directors has established an Audit Committee to meet
with and consider suggestions from members of management and Stamps.com's
internal accounting personnel, as well as Stamps.com's independent accountants,

to review and approve the compensation and benefits for Stamps.com's key

</TABLE>

Each option listed in the table was granted under Stamps.com's 1998 Stock
Plan, which was succeeded by Stamps.com's 1999 Stock Incentive Plan. The
options shown in the table are immediately exercisable. The shares underlying
the options are subject to a repurchase option which expires over a four year
period. The purchase price per share upon exercise of the repurchase option by
us is equal to the exercise price paid by the optionee to originally purchase
the shares. One year after the option grant date, 1/4 of the shares are no
longer subject to the repurchase option and the repurchase option expires for
1/48 of the shares each month thereafter. The shares underlying the options
may also vest fully upon a change in control. See "--1999 Stock Incentive
Plan."

Potential realizable values are net of exercise price, but before the
payment of taxes associated with exercise. Amounts represent hypothetical gains
that could be achieved for the respective options if exercised at the end of
the option term. The 5% and 10% assumed annual rates of compounded stock price
appreciation are mandated by rules of the Securities and Exchange Commission
and do not represent Stamps.com's estimate or projection of Stamps.com's future
common stock prices. These amounts represent assumed rates of appreciation in
the value of the common stock from the fair market value on the date of grant.
Actual gains, if any, on stock option exercises are dependent on the future
performance of the common stock and overall stock market conditions. The
amounts reflected in the table may not necessarily be achieved.

Aggregated Option Exercises and Year-End Option Values

The following table indicates the number and value of unexercised options
held by Stamps.com's officers listed on the Summary Compensation Table. There
was no public trading market for the common stock as of December 31, 1998.
Accordingly, these values of unexercised options have been calculated by
subtracting the exercise price from the fair market value of the underlying
securities as determined by the Board of Directors. No options were exercised
by Stamps.com's executive officers in 1998.

Payne's 1999 compensation includes a base salary of $210,000 per year and a
potential bonus of $90,000. In addition, Stamps.com gave Mr. Payne benefits
that Stamps.com makes available to Stamps.com's employees in comparable
positions, and upon his execution of the letter agreement, Stamps.com sold
1,500,000 shares of Stamps.com common stock to him at $0.07 per share, the fair
market value on the purchase date. Mr. Payne is an at-will employee and his
employment may be terminated at any time by him or by us. If Mr. Payne's
employment is constructively terminated or terminated by us or a successor
entity involuntarily within 12 months following a change in control, or if
Stamps.com terminates or constructively terminates Mr. Payne's employment for
any reason other than for cause, he will be entitled to receive monthly
installments of his base salary for six months and all of his unvested stock
will become immediately vested. After two years of employment, Mr. Payne's
severance period will increase to nine months, and after three years of
service, the severance period will increase to one year.

John W. LaValle entered into a letter agreement, effective as of August 16,
1998, to serve as Stamps.com's Chief Financial Officer and Senior Vice
President. Mr. LaValle receives a base salary of $156,000 per year and was
granted an option to purchase 395,802 shares of Stamps.com common stock at
$0.07 per share, the fair market value on the grant date. In February 1999, Mr.
LaValle's base salary was increased to $185,000 per year. In October 1999, Mr.
LaValle was granted an option to purchase 104,198 shares of Stamps.com common
stock with an exercise price of $35.625, the fair market value on the grant
date. In addition, Mr. LaValle receives standard medical and dental benefits
available to Stamps.com's other employees. Mr. LaValle is an at-will employee
and his employment can be terminated at any time by him or by us. If Mr.

Mohan P. Ananda entered into an employment agreement, effective as of
January 20, 1998, under which Mr. Ananda served as Stamps.com's President,
Chief Executive Officer and the Chairman of the Board of Directors. Mr. Ananda
received an initial base salary of $60,000, which was increased to $120,000

Stamps.com's operations, but he continues as a director.

Douglas J. Walner is subject to an agreement which partially accelerates
the vesting of his options upon a change in control and his subsequent
termination.

In April 1999, Stamps.com amended Stamps.com's 1998 Stock Plan to adopt a
change in control provision. As a result of this provision, should any
optionee have his or her service involuntarily terminated within eighteen
months following a Corporate Transaction in which his or her options are
assumed by the successor corporation and do not otherwise accelerate at that
time, then those options will accelerate and become fully exercisable for all
of the option shares as fully-vested shares of Stamps.com common stock upon an
involuntary termination. A "Corporate Transaction" under the 1998 Stock Plan
is defined as a merger or consolidation in which securities possessing more
than 50% of the total combined voting power of Stamps.com's outstanding
securities are transferred to a person or persons different from those who
held those securities immediately prior to the transaction, or the sale,
transfer or other disposition of all or substantially all of Stamps.com's
assets in complete liquidation of us. "Involuntary Termination" is defined
under the 1998 Stock Plan as the optionee's involuntary dismissal or discharge
by us for reasons other than misconduct, or the optionee's voluntary
resignation following:

. a change in his or her position with us which materially reduces his or
her responsibilities;

. a reduction in his or her level of compensation by more than 15%; or

. a relocation of the optionee's place of employment by more than 50
miles, and this change, reduction or relocation is effected by us
without the optionee's consent.

Our 1999 Stock Incentive Plan is a successor plan to Stamps.com's 1998
Stock Plan, and includes change in control provisions which may result in the
accelerated vesting of outstanding option grants and stock issuances.

1999 Stock Incentive Plan

The 1999 Stock Incentive Plan serves as the successor program to
Stamps.com's 1998 Stock Plan, and the principal features of Stamps.com's 1999
plan are summarized above in "Approval of Amendment to Stamps.com's 1999 Stock
Incentive Plan."

1999 Employee Stock Purchase Plan

Introduction. Stamps.com's 1999 Employee Stock Purchase Plan was adopted by
the board and approved by the stockholders in June 1999. The plan became
effective on June 24, 1999. The plan is designed to allow Stamps.com's
eligible employees and the eligible employees of Stamps.com's participating
subsidiaries to purchase shares of Stamps.com common stock, at semi-annual
intervals, with their accumulated payroll deductions.

Share Reserve. 300,000 shares of Stamps.com common stock were initially
reserved for issuance. The reserve will automatically increase on the first
trading day in January each year, beginning in calendar year 2000, by an
amount equal to one percent of the total number of outstanding shares of
Stamps.com common stock on the last trading day in December in the prior year.
In no event will any annual increase exceed 521,571 shares. Based upon the
total number of shares outstanding on the last trading day of December 1999,
the number of shares reserved for issuance increased by 409,850 for a total of
709,850 shares reserved for issuance under the plan.

95
<PAGE>

Offering Periods. The plan has a series of successive offering periods, each
with a maximum duration of 24 months. The initial offering period commenced on
June 24, 1999 and ends on the last business day in July 2001. The next offering
period will start on the first business day in August 2001, and subsequent
offering periods will be set by Stamps.com's compensation committee.

Eligible Employees. Individuals scheduled to work more than 20 hours per
week for more than 5 calendar months per year may join an offering period on
the start date or any semi-annual entry date within that period. Semi-annual
entry dates will occur on the first business day of February and August each
year. Individuals who become eligible employees after the start date of an
offering period may join the plan on any subsequent semi-annual entry date
within that offering period.

Payroll Deductions. A participant may contribute up to 15% of his or her
cash earnings through payroll deductions, and the accumulated deductions will
be applied to the purchase of shares on each semi-annual purchase date. The
purchase price per share will be equal to 85% of the fair market value per
share on the participant's entry date into the offering period or, if lower,
85% of the fair market value per share on the semi-annual purchase date.

Semi-annual purchase dates will occur on the last business day of January
and July each year. In no event, however, may any participant purchase more
than 1,200 shares on any purchase date, and not more than 75,000 shares may be
purchased in total by all participants on any purchase date.

Reset Feature. If the fair market value per share of Stamps.com common stock
on any purchase date is less than the fair market value per share on the start
date of the two-year offering period, then that offering period will
automatically terminate, and a new two-year offering period will begin on the
next business day. All participants in the terminated offering will be
transferred to the new offering period.

Change in Control. Should Stamps.com be acquired by merger or sale of
substantially all of Stamps.com's assets or more than fifty percent of
Stamps.com's voting securities, then all outstanding purchase rights will
automatically be exercised immediately prior to the effective date of the
acquisition. The purchase price will be equal to 85% of the market value per
share on the participant's entry date into the offering period in which an
acquisition occurs or, if lower, 85% of the fair market value per share
immediately prior to the acquisition.

Plan Provisions. The following provisions are also in effect under the plan:

. The plan will terminate no later than the last business day of June
2009.

. The board may at any time amend, suspend or discontinue the plan.
However, some amendments may require stockholder approval.

RELATED PARTY TRANSACTIONS

Sales of Securities

Stamps.com has issued shares of Stamps.com common stock to several of
Stamps.com's directors, executive officers and founders. John M. Payne,
Stamps.com's President and Chief Executive Officer, purchased 1,500,000 shares
of Stamps.com common stock in November 1998 for a purchase price of
$100,000.00, which amount includes a note payable to Stamps.com for $99,000.00.
Thomas Bruggere, Stamps.com's Chairman of the Board of Directors, purchased
488,475 shares of Stamps.com common stock in October 1998 and December 1998 for
a total purchase price of $28,460.00. Mohan Ananda, a member of Stamps.com's
board of directors, purchased 2,172,595 shares of Stamps.com common stock in
January 1998 for a total purchase price of $28,967.94. As payment of the
purchase price, Mr. Ananda assigned to us intellectual property rights in his
inventions developed for us and received a license back from us to use those
intellectual property rights in a restricted field of use. A more detailed
description of transactions with Mr. Ananda appears below. In January 1998,
Stamps.com also sold 423,993 shares of Stamps.com common stock to each of
Stamps.com's co-founders, James McDermott, Ari Engelberg and Jeffrey Green, for
a total purchase price of $16,959.72, which amount includes $9,000.00 in notes
payable to Stamps.com.

Stamps.com has issued, in private placement transactions, shares of
preferred stock as follows:

. 3,762,500 shares of Series A preferred stock at $0.40 per share in
February 1998;

. 6,020,000 shares of Series B preferred stock at $0.75 per share in
August, October and November 1998; and

. 5,464,486 shares of Series C preferred stock at $5.49 per share in
February and March 1999.

Transactions with Mr. Ananda

Stamps.com paid $61,000 in March 1998 to Safeware Corporation for employee
salary and patent prosecution expenses incurred on Stamps.com's behalf to
attain patents for us. These patent prosecution expenses consisted primarily of
fees paid to patent counsel and fees paid to the US Patent and Trademark
Office. Mr. Ananda is the majority shareholder in Safeware Corporation.
Stamps.com also reimbursed Mr. Ananda for approximately $20,000 for expenses
incurred on Stamps.com's behalf.

Under Stamps.com's previous agreements with Mr. Ananda, Stamps.com owns all
of the intellectual property developed by Mr. Ananda during the course of his
employment and all of the intellectual property he developed for us before his
formal employment began. Mr. Ananda resigned as Stamps.com's Chief Executive
Officer on January 1, 1999. In May 1999, Stamps.com entered into a separation
agreement and a license agreement with Mr. Ananda to formalize his resignation
and to redefine his intellectual property rights relative to us. The new
license agreement reaffirmed Stamps.com's ownership of the intellectual
property invented by Mr. Ananda. In addition, the license agreement clarified
and narrowed Mr. Ananda's field of use restrictions to limit his license to a
few narrowly defined electronic commerce applications that do not compete with
Stamps.com's Internet postage service.

Consulting Services

Stamps.com paid Mr. Payne $112,800 for consulting services he rendered to us
between May 1998 and October 1998.

In February 1999, Stamps.com entered into a three-year consulting agreement
with Loren Smith under which he will provide marketing and strategic planning
services. Mr. Smith also agreed to serve as a director on Stamps.com's board of
directors and to serve as a member on a board committee. In exchange for these
services, Stamps.com compensated Mr. Smith $120,000 per year, and in
consideration of his consulting services, granted him an option to purchase
135,000 shares of Stamps.com common stock at $0.33 per share. This agreement
terminated in October 1999 upon Mr. Smith's appointment as Stamps.com's
President and Chief Operating Officer. In connection with Mr. Smith's
appointment as President and Chief Operating Officer, Stamps.com granted Mr.
Smith an option to purchase 300,000 shares of Stamps.com common stock at an
exercise price of $35.625 per share. The options were granted at fair market
value and vest over a period of two years.

<PAGE>

On June 21, 1999, Stamps.com entered into a consulting services agreement
with Carolyn Ticknor, a director, to provide us with strategic planning and
business development advice, and other consulting services that Stamps.com may
request. In exchange for these services, Stamps.com granted Mrs. Ticknor an
option to purchase 10,000 shares of Stamps.com common stock at an exercise
price of $11.00 per share. This agreement expired on October 1, 1999.

with Marvin Runyon under which he will provide strategic planning services. In
exchange for these services, Stamps.com granted Mr. Runyon an option to
purchase 36,000 shares of Stamps.com common stock. These options were granted
at fair market value and vest ratably over a three-year period. In November

Anti-Takeover Effects of Provisions of Delaware Law and Stamps.com's
Certificate of Incorporation and Bylaws

Delaware Section 203. Stamps.com is subject to the provisions of Section 203
of the Delaware General Corporation Law. Subject to exceptions, Section 203
prohibits a publicly-held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years from
the date of the transaction in which the person became an interested
stockholder, unless the interested stockholder attained this status with the
approval of the board of directors or unless the business combination is
approved in a prescribed manner. A "business combination" includes mergers,
asset sales and other transactions resulting in a financial benefit to the
interested stockholder. Subject to exceptions, an "interested stockholder" is a
person who, together with affiliates and associates, owns, or within three
years did own, 15% or more of the corporation's voting stock. This statute
could prohibit or delay the accomplishment of mergers or other takeover or
change in control in attempts with respect to us and, accordingly, may
discourage attempts to acquire us.

In addition, provisions of Stamps.com's certificate of incorporation and
bylaws, may be deemed to have an anti-takeover effect and may delay, defer or
prevent a tender offer or takeover attempt that a stockholder might consider in
his best interest, including those attempts that might result in a premium over
the market price for the shares held by Stamps.com's stockholders.

Advance Notice Requirements for Stockholder Proposals and Director
Nominations. The bylaws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for
election as directors at an annual meeting of stockholders, must provide timely
notice thereof in writing. To be timely, a stockholder's notice must be
delivered to or mailed and received at Stamps.com's principal executive offices
not less than 120 days prior to the date of Stamps.com's annual meeting. The
bylaws also specify requirements as to the form and content of a stockholder's
notice. These provisions may preclude stockholders from bringing matters before
an annual meeting of stockholders or from making nominations for directors at
an annual meeting of stockholders.

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

Classified Board of Directors; Removal. Stamps.com's directors are divided
into three classes. The classification of the Board of Directors has the effect
of requiring at least two annual stockholder meetings, instead of one, to
replace a majority of the directors which could have the effect of delaying or
preventing a change in control of Stamps.com. Subject to the rights of the
holders of any outstanding series of preferred stock, Stamps.com's certificate
of incorporation authorizes only Stamps.com's board of directors to fill
vacancies, including newly created directorships. The certificate of
incorporation also provides that directors may be removed by stockholders only
for cause and only by the affirmative vote of holders of two-thirds of the
outstanding shares of voting stock.

107
<PAGE>

Supermajority Vote to Amend Charter and Bylaws. Stamps.com's certificate of
incorporation and bylaws each provides that our bylaws may only be amended by
a two-thirds vote of the outstanding shares. In addition, Stamps.com's
certificate of incorporation provides that its provisions related to bylaw
amendments, staggered board and indemnification may only be amended by a two-
thirds vote of the outstanding shares.

Holders of approximately 25,043,074 shares of Stamps.com common stock are
entitled to registration rights with respect to their shares. Of these shares,
2,172,595 shares of Stamps.com common stock do not have demand registration
rights and are only entitled to "piggy-back" registration rights. The holders
of securities with registration rights can require us to register all or part

RIGHTS OF DISSENTING ISHIP.COM SHAREHOLDERS

Generally, shareholders of a Washington corporation who dissent from a
merger of the corporation for which a shareholders' vote is required are
entitled to appraisal rights, requiring the surviving corporation to purchase
the dissenting shares at fair value. In accordance with Chapter 23B.13 of the
Washington Business Corporation Act, holders of shares of capital stock of
iShip.com stock will be entitled to dissenters' rights in connection with the
merger.

If the merger is consummated, dissenting shareholders of iShip.com will be
entitled to be paid the fair value of their shares immediately prior to the
effective time of the merger by complying with the provisions of the WBCA. The
following is a brief summary of the WBCA provisions relating to dissenters'
rights. It is qualified in its entirety by reference to the applicable
statutory provisions of the WBCA, a copy of which is attached hereto as Annex C
and which is incorporated by reference. Shareholders should consult their legal
counsel for advice concerning dissenters' rights as failure to follow the
dissenting procedures exactly could result in the loss of their rights.
iShip.com shareholders should assume that iShip.com will take no action to
perfect any appraisal rights of any shareholder.

If the merger is consummated, iShip.com shareholders who have not consented
to the merger will have the right to demand an appraisal of the fair value of
their shares of iShip.com Common Stock, iShip.com Series A Preferred Stock or
iShip.com Series B Preferred Stock in accordance with the provisions of Section
23B.13 of the WBCA, which sets forth the rights and obligations of iShip.com
shareholders demanding an appraisal and the procedures to be followed.
Shareholders who properly perfect appraisal rights will not be entitled to
surrender their shares of iShip.com common stock, iShip.com Series A Preferred
Stock or iShip.com Series B Preferred Stock for payment in the manner otherwise
provided in the merger agreement.

The demand for appraisal must be delivered to the address set forth below
prior to the later of 20 days after delivery or this document to you and the
date on which iShip.com receives sufficient shareholder approval of the merger.
The demand for appraisal must be executed by or for the holder of record, fully
and correctly, as the holder's name appears on the holder's certificates
evidencing shares of iShip.com stock. If the shares are owned of record in a
fiduciary capacity, like a trustee, guardian or custodian, the demand should be
made in that capacity, and if the shares are owned of record by more than one
person, as in a joint tenancy or tenancy in common, the demand must be made by
or for all owners of record. An authorized agent, including one or more joint
owners, may execute the demand for appraisal for a holder of record, but the
agent must identify the record owner or owners and expressly disclose in the
demand that the agent is acting as agent for the record owner or owners of
shares.

The written demand for appraisal should set forth the number of shares
covered by the demand. Unless a demand for appraisal specifies a number of
shares, the demand will be presumed to cover all shares of any class held in
the name of the record owner. A holder of record may assert dissenters' rights
as to fewer than all the shares registered in the shareholder's name only if
the shareholder dissents with respect to all shares beneficially owned by any
one person and notifies the corporation in writing of the name and address of
each person on whose behalf the shareholder asserts dissenters' rights.

If the merger is approved by shareholders of iShip.com, iShip.com shall send
written notice not later than ten days after the effective time of the merger
to each of its dissenting shareholders stating where a shareholder must send
his or her written payment demand, stating where and when certificates
representing shares of capital stock of iShip.com must be deposited, containing
a form for demanding payment which requires that the dissenter certify whether
or not he or she acquired beneficial ownership before the first public
announcement of the merger on October 25, 1999, and setting a date by which
written payment demand must be received. An iShip.com dissenting shareholder
who does not demand payment, certify that the shareholder acquired the shares
on or before October 25, 1999, and deposit his or her shares with in the time
provided by the notice will not be entitled to dissenters' rights.

109
<PAGE>

iShip.com shall pay to each iShip.com dissenting shareholder who complies
with the procedures described above, within thirty days after the later of the
effective time of the merger and the date the payment demand is received, the
amount that iShip.com estimates to be the fair value of his or her shares, plus
accrued interest. iShip.com will provide, along with payment, financial
information, including iShip.com's balance sheet, income statement and
statement of changes in shareholders' equity for its last fiscal year and
iShip.com's latest available interim financial statements, an explanation of
how iShip.com estimated the fair value of the shares, an explanation of how the
accrued interest was calculated and other information. iShip.com may elect to
withhold payment from any dissenter who was not the beneficial owner of the
shares as to which dissenters' rights are asserted prior to October 25, 1999,
and send a statement to the dissenter setting forth its estimate of the fair
value of such shares and offering to pay that amount, with interest, as a final
settlement of the dissenter's demand for payment. Any dissenting shareholder
who is dissatisfied with that payment or offer may, within thirty days of
payment or offer of payment, notify iShip.com in writing of that shareholder's
estimate of fair value of his or her shares and the amount of interest due and
demand payment thereof.

If any iShip.com dissenting shareholder's demand for payment is not settled
within sixty days after receipt by iShip.com of the shareholder's payment
demand, the WBCA requires that iShip.com commence a proceeding in King County
Superior Court and petition the court to determine the fair value of the shares
and accrued interest, naming all iShip.com dissenting shareholders whose
demands remain unsettled as parties to the proceeding. The court may appoint
one or more persons as appraisers to receive evidence and recommend the fair
value of the shares. The dissenters will be entitled to the same discovery
rights as parties in other civil actions. Each dissenter made a party to the
proceeding will be entitled to judgment for the amount, if any, by which the
court finds the fair value of his or her own shares, plus interest, exceeds the
amount paid by iShip.com.

Holders of shares of capital stock of iShip.com should recognize that a
determination of fair value could result in a price higher than, lower than or
equal to the price available to iShip.com shareholders pursuant to the merger.
Under the WBCA, a court may consider a variety of factors in determining the
fair value and may not give undue emphasis to any one factor.

Court costs and appraisal fees would be assessed against iShip.com, except
that the court may assess costs against some or all of the dissenters to the
extent that the court finds the dissenters acted arbitrarily, vexatiously or
not in good faith in demanding payment. The court may also assess the fees and
expenses of counsel and experts of the respective parties in amounts that the
court finds equitable against iShip.com if the court finds that it did not
substantially comply with provisions of the WBCA concerning dissenters' rights,
or against the dissenter if the court finds that the party against whom the
fees and expenses are assessed acted arbitrarily, vexatiously or not in good
faith. If the court finds that services of counsel for any dissenter were of
substantial benefit to other dissenters similarly situated, and that the fees
should not be assessed against iShip.com, the court may award to counsel
reasonable fees to be paid out of the amounts awarded to dissenters who
benefited from the proceedings.

Any iShip.com shareholder who elects to exercise appraisal rights must mail
or deliver the written demand for appraisal to: iShip.com, Inc., c/o Venture
Law Group, 4750 Carillon Point, Kirkland, Washington 98033-7355, Attn: David R.
Young.

NOTE: IF THE MERGER IS APPROVED, AND YOU DELIVER A WRITTEN DEMAND FOR
APPRAISAL PRIOR TO THE LATER OF 20 DAYS AFTER DELIVERY OF THIS DOCUMENT TO YOU
AND THE DATE ON WHICH ISHIP.COM RECEIVES SUFFICIENT SHAREHOLDER APPROVAL OF THE
MERGER, AND YOU DO NOT VOTE IN FAVOR OF THE MERGER, STAMPS.COM WILL SEND YOU
MORE INSTRUCTIONS ON YOUR DISSENTERS' RIGHTS. FAILURE TO TAKE ANY REQUIRED STEP
IN CONNECTION WITH EXERCISING DISSENTERS' RIGHTS MAY RESULT IN THE TERMINATION
OR WAIVER OF RIGHTS.

SHARES ELIGIBLE FOR FUTURE SALE

Stamps.com estimates that approximately 11.5 million of the 41.0 million
outstanding shares of Stamps.com common stock are freely tradable. On December
22, 1999, upon the expiration of lock-up agreements entered into in connection
with Stamps.com's initial public offering, an additional 2.1 million
outstanding shares of common stock became available for immediate sale. On
February 4, 2000, the lock-up described below will expire for approximately 6.8
million shares of Stamps.com's outstanding common stock and, on March 5, 2000,
the lock-up described below will expire for all remaining shares subject to the
lock-up. Prior to these dates, shares subject to lock-up agreements cannot be
offered or sold without the prior written consent of Goldman, Sachs & Co. All
of the shares subject to the lock-up will be 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 resale.

Stamps.com is unable to estimate the number of shares that will be sold
under Rule 144, since this will depend on the market price for its common
stock, the personal circumstances of the sellers and other factors. Any future
sale of substantial amounts of Stamps.com common stock in the open market may
adversely affect the market price of the Stamps.com common stock offered by
this document.

As part of the follow-on public offering completed in December 1999,
Stamps.com's executive officers and directors, other significant stockholders
and iShip.com's significant stockholders, who will receive at least 95% of the
shares of Stamps.com common stock to be issued in the acquisition of iShip.com,
executed agreements with the underwriters that they will not offer or sell any
shares of Stamps.com common stock until February 4, 2000 without the prior
written consent of Goldman, Sachs & Co. On February 4, 2000, the lock-up will
expire for 20% of the shares held by these stockholders. On March 5, 2000, the
lock-up will expire for the remaining 80% of the shares held by these
stockholders. Prior to these dates, any shares subject to lock-up agreements
cannot be offered or sold without the prior written consent of Goldman, Sachs &
Co. This agreement does not apply to shares reserved for issuance to non-
director, non-execute officer employees under existing employee benefit plans.
In addition, the merger agreement provides that Stamps.com is not obligated to
file an S-8 registration statement for options assumed in the acquisition until
the expiration of the 90 day lock-up period subject to lock-up agreements for
the follow-on offering, which date is March 5, 2000 . Goldman, Sachs & Co. may,
in its sole discretion, at any time and without notice, release all or a
portion of the shares of common stock subject to these agreements. Sales of
substantial amounts of Stamps.com common stock in the public market, or the
perception that these sales could occur, could adversely affect the prevailing
market price for the Stamps.com common stock and could impair Stamps.com's
ability to raise capital through a public offering of equity securities.

LEGAL MATTERS

1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on the financial
statements based on our audit.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Stamps.com Inc. as of

NOTES TO FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Description of Business and Basis of Presentation

Stamps.com Inc. (Stamps.com Inc. or the Company) was incorporated in
Delaware on January 9, 1998, and is a development stage company. Its primary
activities since inception have been to develop an Internet-based postage
service for end-users and raise capital to finance operations.

The Company is subject to the normal risks associated with a development
stage enterprise in the technology industry. These risks include, among others,
the risks associated with product development, commercial roll-out of its
Internet postage service, US Postal Service regulation, acceptance of the
product by end users and the ability to raise additional capital to sustain
operations.

On August 9, 1999, the Company's Internet Postage service was approved by
the US Postal Service for commercial release. On October 22, 1999, the Company
commercially launched its Internet Postage service.

Unaudited Interim Financial Information

The interim financial statements of the Company for the period from January
9, 1998 (date of inception) to September 30, 1998 and the nine months ended
September 30, 1999, included herein have been prepared by the Company, without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to such rules and
regulations relating to interim financial statements. In the opinion of
management, the accompanying unaudited interim financial statements reflect all
adjustments, consisting only of normal recurring adjustments, necessary to
present fairly the financial position of the Company at September 30, 1999, the
results of operations and its cash flows for the period from January 9, 1998
(date of inception) to September 30, 1998 and the nine months ended September
30, 1999.

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 Equivalents

Cash equivalents include demand deposits and short-term investments with a
maturity of three months or less when purchased.

Concentration of Risk

The financial instrument that potentially exposes the Company to
concentrations of credit risks consists primarily of cash equivalents. The
Company places its cash equivalents with high quality financial institutions.
At times, such balances may be in excess of the FDIC insurance limit.

Reclassifications

Certain reclassifications have been made to prior periods to conform to
current period presentations.

Computation of Historical Net Loss per Share and Pro Forma Net Loss Per Share

In accordance with Statement of Financial Accounting Standards (SFAS) No.
128, "Computation of Earnings 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.

A summary of the shares used to compute earnings per share is as follows:

conversion of the Company's Series A, B and C Preferred Stock into shares of
the Company's Common Stock effective upon the closing of the Company's Initial
Public Offering as if such conversion occurred at inception or the date of
original issuance, if later. Pro forma diluted earnings per share is computed
using the pro forma weighted average number of common and common equivalents
shares outstanding during the period, to the extent such shares are dilutive.

Advertising Costs

The Company generally expenses the costs of producing advertisements at the
time the advertising first runs, and expenses the costs of communicating
advertising in the period in which the advertising space or airtime is used.

Internet advertising expenses are recognized based on specifics of the
individual agreements. Under impression based agreements, advertising expense
is recognized using the ratio of the number of impressions delivered over the
total number of contracted impressions while agreements based on a period of
time recognize advertising expense on the straight-line basis over the term of
the contract.

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are
computed principally on a straight-line method over the estimated useful lives
of the assets ranging from three to five years. Assets acquired under
capitalized lease arrangements are recorded at the present value of the minimum
lease payments. Amortization of assets capitalized under capital leases is
computed using the straight-line method over the life of the asset or term of
the lease, whichever is shorter. Expenditures for repairs and maintenance are
charged to expense as incurred.

Property and equipment is comprised of the following:

</TABLE>
Other Assets

Patents, trademarks and other intangibles are included in other assets in
the accompanying balance sheets and are carried at cost less accumulated
amortization. Amortization is calculated on a straight-line basis over the
estimated useful lives of the assets, ranging from 5 to 15 years.

Income Taxes

The Company accounts for income taxes in accordance with FASB 109,
"Accounting for Income Taxes." Under this method, deferred tax liabilities and
assets are determined based on the difference between the financial statements
and the tax basis of assets and liabilities using the enacted tax rate in
effect for the years in which the differences are expected to reverse.

Research and Development Costs

Research and development costs are expensed as incurred. These costs
primarily consist of salaries, development materials, supplies and applicable
overhead expenses of personnel directly involved in the research and
development of new technology and products.

Website Development Costs

The Company developed and maintains its website. Costs associated with the
website consist primarily of software purchased from third parties. Currently,
the Company capitalizes costs of computer software obtained for internal use in
web design and network operations. These capitalized costs are amortized based
on their estimated useful life. Payroll and related costs are not capitalized,
as the amounts are immaterial and principally relate to maintenance. Costs
related to the development of website content are expensed as incurred.

Stock-Based Compensation

SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS 123)
encourages, but does not require, companies to record compensation cost for
stock-based employee compensation plans at fair value. The Company has chosen
to continue to account for stock-based compensation using the intrinsic-value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees."

2. Line of Credit

On May 1, 1998, the Company entered into a credit line agreement with a
lender. The initial $300,000 borrowing base was increased to $1 million based
on the Company's net equity balance, as defined, through December 31, 1998.
Borrowings bear interest at the lender's prime rate plus 1% (8.75% at December
31, 1998) and are collateralized by certain of the Company's assets. The
Company used the amount drawn for working capital purposes. The unpaid balance
due under the line of credit at February 9, 1999 may be converted to a term
loan payable in 24 equal monthly installments commencing on such date.
Otherwise, the credit line agreement matures on October 8, 1999.

In connection with this indebtedness agreement, the Company issued a
detachable warrant which permits the holder to purchase 7,050 shares of the
Company's Common Stock for $.27 per share. The term of this warrant is for a
period of seven years from the date of grant.

3. Income Taxes

The provision for income taxes consists solely of minimum state taxes. The
Company's effective tax rate differs from the statutory federal income tax rate
primarily as a result of the establishment of a valuation allowance for the
future benefits to be received from the net operating loss carryforwards and
research tax credit carryforwards. The tax effect of temporary differences that
give rise to a significant portion of the deferred tax assets and liabilities
at December 31, 1998 are presented below.

<TABLE>
<S> <C>
Deferred tax assets (liabilities):
Net operating loss carryforwards............................. $ 537,154
Research credits............................................. 150,000
Depreciation................................................. (28,006)
Capitalized start-up costs................................... 988,403

-----------
Total deferred tax assets...................................... 1,693,619
Valuation allowance............................................ (1,693,619)
-----------
Net deferred tax assets........................................ $ --
===========
</TABLE>

Because the Company is uncertain when it may realize the benefits of its
favorable tax attributes in future returns, the Company has placed a valuation
allowance against its otherwise recognizable deferred tax assets. In 1998, the
valuation allowance recorded was $1,693,619.

The Company has a net operating loss carryforward for federal and state
income tax purposes at December 31, 1998 of $1,348,467, and an available tax
credit carryforward at December 31, 1998 of $150,000, each of which can be
carried forward to offset future taxable income, if any. The Company's federal
net operating loss expires starting in 2018, state net operating loss expires
starting in 2006, and credits expire starting in 2018. The Federal Tax Reform
Act of 1986 and similar state tax laws contain provisions which may limit the
net operating losses carryforwards to be used in any given year upon the
occurrence of certain events, including a significant change in ownership
interests.

The Company currently rents its facilities on a month-to-month basis or for
terms less than one year. Total rent expense for the period from January 9,
1998 through December 31, 1998 was $109,428 and includes $23,400 paid to a
stockholder/officer for rental of office space.

In December 1998, the Company entered into a Distribution and Marketing
Agreement with America Online, Inc. (AOL) that provides broad distribution and
marketing campaigns amongst AOL's diverse properties. In exchange for these
services, the Company is required to make minimum payments that approximate
$1,700,000 and $525,000 in 1999 and 2000, respectively. In exchange for these
services, the Company is required to pay $2.3 million in varied amounts through
February 2000 ($75,000 in 1998, $1,700,000 in 1999 and $525,000 in 2000). The
Company may purchase additional advertising under this Marketing and
Distribution Agreement but it is not required. The Company will recognize the
related expense upon performance of services (see note 8).

5. Stock Options

In January 1998, the Company adopted the 1998 Stock Option Plan (the Plan)
which authorizes the Board of Directors to grant incentive stock options,
nonqualified stock options and stock purchase rights (collectively options) to
employees, directors, consultants and advisors of the Company. The maximum
number of shares of common stock to be issued under the Plan is 7,290,000. All
options granted under the Plan have been made at prices not less than fair
value of the stock at the date of grant, as determined by the Board of
Directors. Options granted under the Plan are generally exercisable
immediately, however, they vest 25% per year, and the Board of Directors has
the discretion with respect to vesting periods applicable to a particular
grant. During 1998, the Company issued options to purchase 2,347,471 shares of
common stock at prices which included approximately $600,000 of a compensation
element. The $600,000 is being recognized as expense over the vesting periods
of the related options and has been presented as a reduction of stockholders'
equity (deficit) in the accompanying balance sheets.

As of December 31, 1998, all options were exercisable. However, no options
were vested and 1,904,091 were available for future grant. The weighted average
remaining contractual life of the outstanding stock options at December 31,
1998, is 9.7 years.

Pro forma information regarding net loss is required by SFAS 123, and has
been determined as if the Company had accounted for its employee stock options
under the fair-value method of that statement. The fair value for these options
was estimated at the date of grant using the minimum-value method, which
utilizes a near-zero volatility factor. The remaining assumptions, which are
weighted average, under this method are as follows:

<TABLE>
<S> <C>
Expected life (years).................................................. 5
Risk-free interest rate................................................ 5.50%
Dividend yield......................................................... --
</TABLE>

This option-valuation method requires input of highly subjective
assumptions. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because change in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing method does not necessarily provide a
reliable single measure of the fair value of its employee stock options. The
effects of applying SFAS 123 in this pro forma disclosure are not indicative of
future amounts and additional awards in future years are anticipated.

Had compensation cost for the Company's stock-based compensation plan been
determined based on the fair value of the grant dates for the awards under a
method prescribed by SFAS 123, the Company's net loss would have been increased
to the pro forma amounts indicated below:

6. Related Party Transactions

The Company paid $61,000 in March 1998 to Safeware Corporation for employee
salary and patent prosecution expenses incurred to obtain a patent. These
patent prosecution expenses consisted primarily of fees paid to patent counsel
and fees paid to the US Patent and Trademark Office. A director of the Company
is the majority shareholder in Safeware Corporation. The Company also
reimbursed the director for approximately $20,000 for expenses incurred on its
behalf.

7. Stock Transactions

During 1998, the Company issued restricted stock to an employee and a
director totaling 1,988,475 shares. These shares vest one-fourth on May 30,
1999 and the remaining shares vest monthly over the subsequent thirty-six
months. The Company issued these shares at prices which included approximately
$650,000 of a compensation element. The $650,000 is being recognized as expense
over the vesting periods and has been presented as a reduction of stockholders'
equity (deficit) in the accompanying balance sheets.

In February 1998, the Company issued 3,762,500 shares of its Series A
Redeemable Preferred Stock at $0.40 per share and warrants to acquire 6,020,000
shares of the Company's its Series B Redeemable Preferred Stock at $0.75 per
share. In August and October 1998, 6,020,000 shares of Series B Redeemable
Preferred Stock were issued under these warrants.

Redeemable Preferred stock is convertible to common stock on a one-for-one
basis at the option of the holder at any time after issuance, subject to anti-
dilution protection. Each share of Redeemable Preferred Stock automatically
converts to Common Stock upon (i) the sale of Common Stock by the Company in an
underwritten public offering with a public offering price of $2.00 per share
and net proceeds of $15 million or (ii) written consent of the majority holders
of outstanding shares of Preferred Stock (see Note 8).

The holders of Redeemable Preferred Stock are entitled to receive non-
cumulative dividends in preference to the Common stock at a rate of $0.040 and
$0.075 per share per annum, respectively, or if greater (as determined on a per
annum basis and an as converted basis for Redeemable Preferred Stock), an
amount equal to that paid on any other outstanding share, payable quarterly
when, as and if declared. No dividends can be paid or declared on any Common
Stock unless full cash dividends, including past dividends declared, have been
paid on the Redeemable Preferred Stock.

The Series A and Series B Redeemable Preferred Stock have a liquidation
preference over Common Stock of $0.40 and $0.75 per share, respectively.

The Redeemable Preferred Stock may be redeemed at any time after February
26, 2003 at the written consent of the majority holders of outstanding shares
of Redeemable Preferred Stock. The redemption price for Series A and Series B
Redeemable Preferred Stock is $0.40 and $0.75 per share, respectively. Series A
and Series B Redeemable Preferred Stock has been reflected in the accompanying
balance sheets outside of stockholders' equity (deficit) due to its redemption
feature.

In connection with the issuance of Common Stock during the period, the
Company exchanged shares with a fair value of $117,000 for notes receivable of
the same amount. These notes receivable bear interest at 9% per annum and are
payable in February 2003.

8. Events Subsequent to the Date of the Auditors' Report (Unaudited)

Redeemable Preferred Stock

On February 10, 1999, the Board of Directors approved the sale of Series C
Redeemable Preferred Stock. In February and March 1999, the Company issued
5,464,486 shares of its Series C Redeemable Preferred Stock at $5.49 per share.
Series C Redeemable Preferred Stock is convertible to common stock on a one-
for-one basis at the option of the holder at any time after issuance, subject
to anti-dilution protection. In connection with the sale of Series C Redeemable
Preferred Stock, the board of directors amended the certificate of
incorporation and each share of Series A, Series B and Series C Redeemable
Preferred Stock automatically converts to Common Stock upon (i) the sale of
Common Stock by the Company in an underwritten public offer with a public
offering price of at least $10.98 per share and net proceeds of $20 million or
(ii) written consent of the majority of holders of outstanding shares of
Redeemable Preferred Stock. In connection with the Company's Initial Public
Offering in June 1999, all shares of Series A, B, and C Preferred Stock
converted into 22,870,479 shares of Common Stock.

Authorized Stock and Stock Dividend

On February 17, 1999, the Company increased the number of authorized shares
of common stock and preferred stock to 40,000,000 shares and 15,500,000 shares,
respectively. Subsequent to year end, the Board of Directors increased the
number of shares reserved for issuance under the 1998 Stock Option Plan to
7,290,000 shares.

In June 1999, the Board of Directors declared a stock dividend of 3 shares
of Common Stock for every 2 shares of Common Stock then outstanding, an action
which also resulted in an adjustment to the conversion ratio of the Series A, B
and C redeemable preferred stock to a three-for-two basis. The stock dividend
became effective on the date that the Company's public offering of Common Stock
closed. Accordingly, the accompanying financial statements and footnotes have
been restated to reflect the stock dividend. In addition the board changed the
number of authorized shares of Common Stock and Preferred Stock to 95,000,000
and 5,000,000 shares, respectively.

Stock options

The estimated fair value for these options was estimated at the date of
grant using the minimum-value method using the same assumptions as Note 5. From
January 1, 1999 through September 30, 1999, the Company issued options to
purchase approximately 4,097,000 shares of common stock at prices which
included a compensation element of approximately $9,513,000. This compensation
element is being recognized as an expense over the vesting periods of the
related options and the unrecognized portion has been presented as a reduction
of stockholders' equity (deficit) in the accompanying balance sheets.

Commitments

In May 1999, the Company entered into a facility lease agreement for its
corporate headquarters with minimum lease payments totaling $4.8 million over 5
years.

Also in May 1999, the Company entered into a Sponsorship Agreement with
Intuit Inc. (Intuit) that markets our Internet postage service on various
Intuit internet sites and software. In exchange for this sponsorship, the
Company is required to pay $3.3 million ($2 million in 1999 and $1.3 million in
2000). Additional payments may be required if this Sponsorship Agreement
results in certain customer levels. The related expense will be recognized as
the services are provided.

In October 1999, the Company entered into a three-year marketing and
distribution agreement with America Online, Inc. ("AOL"). This partnership is
an expansion of our agreement with AOL made in December 1998. Under the new
agreement, the Company will be provided with a specific number of advertising
impressions across several AOL brands featuring it as the exclusive provider of
Internet postage services. Stamps.com software will also be included in AOL
branded CD-ROMs for distribution.

In consideration, the Company has committed to pay $56.0 million over the
three-year term of the agreement. Of the $56.0 million total commitment, $20.5
million will be paid during the twelve months ended September 30, 2000. The
Company is recognizing these fees as sales and marketing expense over the term
of the contract based primarily on the ratio of the number of impressions
delivered over the total number contracted.

In connection with the new AOL agreement, the Company issued 178,638 shares
of common stock in October 1999 for $6.0 million in the aggregate, or $33.588
per share. In December 1999, the Company issued an additional 148,862 shares of
common stock for $5.0 million in the aggregate, or $33.588 per share. The total
shares owned by AOL as a result of the transaction is 327,500. The Company also
issued AOL a warrant, which is exercisable at $33.588 per share for 50 percent
of the total common stock shares purchased by AOL. The warrant also allows for
the purchase of additional Common shares (50 percent of the unexercised portion
of the warrant) in the event the Company is unable to cure a material breach of
the payment provisions of the marketing and distribution agreement.

Related Party Transactions

In February 1999, a director entered into a three-year consulting agreement
with the Company to provide marketing and strategic planning services. In
exchange for his consulting services, the director will receive consulting fees
of $120,000 per annum and an option to purchase 135,000 shares of common stock
at $0.33 per share. In the nine-month period ended September 30, 1999, a
compensation element of approximately $180,000 was calculated using the Black-
Scholes valuation model for the options earned during the period. This
agreement was terminated in October 1999 upon the director's appointment as an
officer of the Company. This change in status will result in a new measurement
date for the remaining unvested options. The compensation expense resulting for
the new measurement date will be recognized over the remaining vesting period.

On June 21, 1999, the Company entered into a consulting services agreement
with a director to provide us with strategic planning and business development
advice, and other consulting services that the Company may request. In exchange
for these services, the Company granted the director an option to purchase
10,000 shares of common stock at an exercise price of $11.00 per share. This
agreement expired on October 1, 1999.

In October 1999, a director entered into a three-year consulting agreement
with the Company to provide strategic planning services. In exchange for his
consulting services, the director received an option to purchase 36,000 shares
of common stock at $35.625 per share. A compensation element for these options
will be recorded each month as the options vest, based on the Black-Scholes
valuation method.

In November 1999, this agreement was amended to provide that the director
would receive consulting fees of $2,000 per day for any special projects on
which the Company requires his services.

Legal Proceedings

On June 16, 1999, Pitney Bowes filed a patent infringement lawsuit against
the Company. The suit alleges that the Company is 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.
The Company 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 the Company's
competitors, E-Stamp Corporation, alleging infringement of seven Pitney Bowes
patents.

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

If Pitney Bowes prevails in its claims against the Company, it may be
prevented from selling postage on the Internet. Alternatively, the Pitney Bowes
suit could result in limitations on how the Company implements its service,
delays and costs associated with redesigning its service and payments of
license fees and other payments. In addition, the litigation could result in
significant expenses and diversion of management time and other resources.
Thus, if Pitney Bowes prevails in its suit against the Company, its business
could be severely harmed or fail. The Company believes a reasonable possibility
exists that a loss may be incurred. However, the Company cannot provide an
estimate of possible loss or range of loss at this time.

On December 29, 1999, three individuals filed a lawsuit against the Company,
asserting claims for breach of contract, quantum meruit, fraud and negligent
misrepresentation. At this time, it is the Company's intent to file a response
to the complaint which denies these allegations, and to vigorously defend this
suit. However, there can be no assurances that the Company will prevail in this
suit. Due to the preliminary stage of this lawsuit, the Company is unable to
estimate the potential loss or range of potential loss at this time.

Initial Public Offering

In June and July 1999, the Company completed an initial public offering in
which the underwriters sold to the public 5,750,000 shares of Common Stock,
including 750,000 shares in connection with the exercise of the underwriters'
over-allotment option, at $11.00 per share. The Company's proceeds from the
offering, after deducting underwriting discounts and commissions, were $10.23
per share, or $58,822,500 in the aggregate. Upon the closing of that offering,
the Company repurchased 704,595 shares of Common Stock for $939,460 and
converted all the Company's Redeemable Preferred Stock to Common Stock. After
the offering, the Company's authorized capital consists of 95,000,000 shares of
Common Stock of which 34,864,807 shares were outstanding at September 30, 1999.

Acquisition

In October 1999, the Company entered into a merger agreement with iShip.com,
a development stage enterprise developing Internet-based shipping technology.
In connection with the proposed merger, an aggregate of up to 8,000,000 of the
Company's common stock will be issued and reserved for issuance. The agreement
is subject to shareholder approval by both companies, and other customary
conditions.

The acquisition will be accounted for using the purchase method of
accounting. Accordingly, a portion of the purchase price will be allocated to
the tangible and intangible assets acquired and liabilities assumed based on
their respective fair values on the acquisition date. The company is currently
in process of preparing the final purchase price allocation and determining the
useful lives of the assets acquired. It is anticipated that the purchase would
result in intangible assets of approximately $288.8 million.

1999 Stock Incentive Plan

In October 1999, the Company's Board of Directors approved an increase of
2,500,000 shares to the number of shares eligible to be granted under the 1999
Stock Incentive Plan. Upon stockholder approval of the increase, the total
shares authorized for issuance under the 1999 Stock Incentive Plan will be
11,019,551, which amount includes an automatic annual increase to the share
reserve of 3% of the Company's outstanding common shares on the last trading

40,985,054 shares outstanding on the last trading day of December 1999.

Follow-On Public Offering

In December 1999, the Company completed a follow-on public offering in which
the underwriters sold to the public 5,750,000 shares of common stock, including
750,000 shares in connection with the exercise of the over-allotment option, at
$65.00 per share. The Company's proceeds from the offering, after deducting

INDEPENDENT AUDITOR'S REPORT

To the Stockholders
iShip.com, Inc.

We have audited the accompanying balance sheets of iShip.com, Inc. (a
development stage company) as of December 31, 1997 and 1998, and the related
statements of operations, stockholders' equity and cash flows for the period
from inception (May 27, 1997) to December 31, 1997 and for the year ended
December 31, 1998. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of iShip.com, Inc. as of
December 31, 1997 and 1998, and the results of its operations and its cash
flows for the period from inception (May 27, 1997) to December 31, 1997 and for
the year ended December 31, 1998, in conformity with generally accepted
accounting principles.

NOTES TO FINANCIAL STATEMENTS

Note 1--Summary of Significant Accounting Policies

Development Stage Operations--iShip.com, Inc. (the Company), a Washington
corporation, was incorporated on May 27, 1997 under the name MoveIt! Software,
Inc. On May 18, 1998, the Company changed its name to iShip.com, Inc. The
Company's office is located in Bellevue, Washington.

Since inception, the Company has been developing and marketing software
applications that enable customers to price, ship and track packages using its
website. The Company has devoted significant time to raising capital, obtaining
financing and administrative functions. These activities are expected to
continue until such time the software is released commercially. During 1998, a
"beta" version of the software was released. Limited revenues have been
recognized since inception related to miscellaneous service fees.

Unaudited Interim Financial Information--The interim financial statements of
the Company for the nine months ended September 30, 1998 and 1999 and the
period from May 27, 1997 (date of inception) to September 30, 1999, included
herein have been prepared by the Company, without audit, pursuant to the rules
and regulations of the Securities and Exchange Commission. Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted pursuant to such rules and regulations relating to interim financial
statements. In the opinion of management, the accompanying unaudited interim
financial statements reflect all adjustments, consisting only of normal
recurring adjustments, necessary to present fairly the financial position of
the Company at September 30, 1998 and 1999, the results of operations and its
cash flows for the nine months ended September 30, 1998 and 1999 and the period
from May 27, 1997 (date of inception) to September 30, 1999.

Use of Estimates--The preparation of the 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 accompanying notes. Actual results could differ from those
estimates.

Cash and Cash Equivalents--For the purposes of the statement of cash flows,
cash and cash equivalents are defined as short-term, highly liquid investments
that are readily convertible to cash and are so near maturity that fluctuations
in interest rates lead to insignificant risk of changes in investment value.

Equipment--Equipment is stated at cost. The Company provides depreciation on
the cost of its equipment using straight-line methods over estimated useful
lives of three years. Expenditures for repairs and maintenance are charged to
expense as incurred.

Research and Development Costs--Research and development costs are charged
to expense as incurred. These costs primarily consist of salaries, development
materials, supplies and applicable overhead expenses of personnel directly
involved in the research and development of new technology.

Advertising--The Company expenses advertising costs as incurred. No
advertising costs were incurred during the period from inception (May 27, 1997)
to December 31, 1997 and the year ended December 31, 1998.

Internet advertising expenses are recognized based on specifics of the
individual agreements, advertising expense is recognized using the ratio of the
number of impressions delivered over the total number of contracted impressions
while agreements based on a period of time recognize advertising expense on a
straight-line basis over the term of the contract.

(A Development Stage Company)

NOTES TO FINANCIAL STATEMENTS--(Continued)

Stock-Based Compensation--The Company accounts for stock-based compensation
to employees using the intrinsic value method, whereby, compensation cost is
recognized when the exercise price at the date of grant is less than the fair
market value of the Company's common stock. The Company discloses the proforma
effect of compensation cost based on the fair value method for determining
compensation cost. Stock-based compensation awarded to non-employees is
determined using the fair value method. Compensation cost is recognized over
the service or vesting period.

Income Taxes--Income taxes are accounted for using an asset and liability
approach which requires the recognition of deferred tax assets and liabilities
for the expected future tax consequences of temporary differences between the
financial statement and tax basis of assets and liabilities at the applicable
enacted tax rates. Generally accepted accounting principles require a valuation
allowance against deferred tax assets if, based on the weight of available
evidence, it is more likely than not that some or all of its deferred tax
assets will not be realized.

Risk Concentrations--At times, cash balances exceed federally-insured
limits. However, cash is held on deposit in major financial institutions and is
considered subject to minimum credit risk.

Website Development Costs--The Company developed and maintains its website.
Costs associated with the website consist primarily of software purchased from
third parties. Currently, the Company capitalizes costs of computer software
obtained for internal use in web design and network operations. These
capitalized costs are amortized based on their useful life. Payroll and related
costs are not capitalized, as the amounts are immaterial and principally relate
to maintenance. Costs related to development of website content are expensed as
incurred.

Note 2--Investment Securities

Investment securities are classified as "available-for-sale" under generally
accepted accounting principles. Available-for-sale securities are recorded at
estimated fair value, with the net unrealized gain or loss included as a
separate component of shareholders' equity, net of the related tax effect.
Realized gains or losses on dispositions are based on the net proceeds and the
adjusted carrying amount of securities sold, using the specific identification
method.

At December 31, 1998, the Company had commercial paper with an amortized
cost of $990,676, which approximates fair value. The expected maturities of the
securities range from 25 to 106 days.

Note 3--Equipment

Equipment is recorded at cost and consists of the following at December 31:

Note 4--Long-Term Debt

The Company has an equipment line of credit with a bank providing for
equipment purchase advances up to $500,000 through September 4, 1999. Advances
are collateralized by substantially all assets of the Company. Interest on the
borrowings are at the bank's prime rate plus 0.5%. Monthly interest payments
are required through September 4, 1999. Commencing on October 4, 1999, the
unpaid principal balance of the advances shall be paid in 36 equal monthly
installments of principal plus interest.

Maturities of long-term debt for years ending December 31 are as follows:

Note 5--Deferred Officers' Compensation

Three key officers of the Company deferred their salaries during the first
nine months of development stage operations. The deferred compensation amounts
to $150,000 and $168,750 as of December 31, 1997 and 1998, respectively. The
deferred salaries will be paid when the Company generates positive cash flows
from operations.

Note 6--Preferred Stock

Transactions--The Company issued 1,600,000 shares in 1997 and 7,386,668
shares in 1998 of Series A Preferred Stock at $0.375 per share. No direct costs
were incurred in relation to the shares issued.

Preference in Liquidation--In the event of voluntary or involuntary
liquidation, distribution of assets, dissolution or winding-up of the Company
before any distribution or payment to holders of the Company's common stock,
the holders of Series A Preferred Stock are entitled to receive payment of
$0.375 per outstanding share held by them.

Dividends--Dividends payable to holders of Series A Preferred Stock are at
the discretion of the Company's Board of Directors. As of December 31, 1997 and
1998, no dividends had been declared.

Conversion Rights--A holder of Series A Preferred Stock, at the holder's
option, has the right to convert shares of Series A Preferred Stock into common
stock on a one-for-one basis, subject to adjustment for stock splits and
dilutive issuances. In addition, Series A Preferred Stock would automatically
convert to common stock in the event of the closing of an underwritten public
offering which establishes a valuation of the Company of at least $50 million
and results in gross proceeds of at least $10 million or upon the conversion of
two-thirds of the shares of Series A Preferred Stock originally issued.

Voting Rights--The holders of Series A Preferred Stock are entitled to one
vote for each share and are entitled to vote on all matters on which the
holders of common stock have the right to vote.

Note 7--Stock Option Plan

The Company has a stock option plan under which employees and consultants
may be awarded incentive or nonstatutory stock options. The plan authorizes the
grant of options for the purchase of up to 5,660,000 shares of common stock.
Under the plan, the option exercise price for incentive stock options may

NOTES TO FINANCIAL STATEMENTS--(Continued)

not be less than the fair market value of the Company's common stock at the
date of grant as determined by the Board of Directors, but for nonstatutory
stock options may be less than the fair market value of the Company's common
stock at the date of grant as determined by the Board of Directors. However,
all option grants under the plan to 10% shareholders may not be less than 110%
of fair market value of the Company's common stock at the date of grant as
determined by the Board of Directors. Options expire no later than ten years
from the grant date, and vesting is established at the time of grant provided
that options shall become exercisable at the rate of at least 20% per year over
five years. During 1998, the Company issued options to purchase 759,000 shares
of common stock which included approximately $104,000 of compensation element.
The $104,000 is being recognized as expense over the vesting periods of the
related options and has been presented as a reduction of stockholders' equity
in the accompanying balance sheet.

value method, the proforma net loss would have increased by $4,000 to $410,868
for the period from inception to December 31, 1997 and by $25,000 to $1,886,511
for the year ended December 31, 1998.

The weighted average fair value of the options granted was estimated to be
$0.01 in the period from inception to December 31, 1997 and $0.27 in 1998 using
the Black-Scholes option-pricing model with the following assumptions on the
date of grant: 0% dividend yield and volatility, 5% forfeitures per year, risk-
free interest rate of 4.47% to 5.80%, expected life of five years.

Note 8--Income Taxes

At December 31, 1998, the Company has net operating loss carryforwards for
federal income tax purposes of approximately $1.9 million and research credit
carryforwards of $109,000 available to offset future federal taxable income, if
any. The net operating loss and research credit carryforwards generally expire
in 2018. The Internal Revenue Code may limit the net operating loss
carryforwards to be used in any given year upon the occurrence of certain
events, including significant change in ownership interest.

A valuation allowance for the full amount of the net deferred tax asset has
been recorded as realization in the near term is not reasonably assured. The
provision for income taxes differs from the amount computed by applying the
statutory federal income tax rate of 34% to earnings before taxes due to the
valuation allowance established for the current year's net operating loss and
nondeductible items.

Note 9--Capital Lease Obligation

At December 31, 1997 and 1998, the Company was obligated under the terms of
a capital lease for certain computer hardware and software from a related
party. The implicit interest rate for the leases ranges from 4.4% to 7.5% and
requires monthly payments of $4,534. Required minimum lease payments for the
years ending December 31 are as follows:

NOTES TO FINANCIAL STATEMENTS--(Continued)

Given the Company's development stage operations, only a portion of the
standard lease payments are required in early months. The difference between
the actual lease payments and the standard monthly payments are recorded as
deferred rent payable. Total deferred rent was $50,845 as of December 31, 1998.

The Company subleases a portion of the office space to an unrelated party.
The sublease commenced on June 15, 1998 and provides for monthly rent of
$7,708. The original lease term is twelve months. The subtenant has the right
to extend the sublease for two additional periods of three months each. Rental
income from the sublease totaled $58,069 in 1998.

The Company also leases certain furniture and leasehold improvements to the
third party. Rental income from these leases amounted to $24,044 in 1998.

Note 11--Events Subsequent to the Date of the Auditors' Report (Unaudited)

Series B Preferred Stock--In April 1999 the Board of Directors, approved the
sale of Series B Preferred Stock. In April, May and August, 1999 the Company
issued 10,133,334 shares of its Series B Preferred Stock at $0.75 per share. No
direct costs were incurred in relation to the shares issued. The proceeds of
$7.6 million have been used to fund the operations of the Company with excess
funds at September 30, 1999 invested in short-term, highly-liquid investments
classified as cash equivalents. In the event of voluntary or involuntary
liquidation, distribution of assets, dissolution or winding-up of the Company
before any distribution or payment to holders of the Company's common stock,
the holders of Series B Preferred Stock are entitled to receive payment of
$0.75 per outstanding share held by them. Dividends payable to holders of
Series B Preferred Stock are at the discretion of the Company's Board of
Directors. A holder of Series B Preferred Stock, at the holder's option, has
the right to convert shares of Series B Preferred Stock into common stock on a
one-for-one basis, subject to adjustment for stock splits and dilutive
issuances. In addition, the Series B Preferred Stock would automatically
convert to common stock in the event of the closing of an underwritten public
offering which establishes a valuation of the Company of at least $75 million
and results in gross proceeds of at least $15 million or upon the conversion of
two-thirds of the shares of Series B Preferred Stock originally issued. The
holders of Series B Preferred Stock are entitled to one vote for each share and
are entitled to vote on all matters on which the holders of common stock have
the right to vote.

Stock Warrant--On April 27, 1999 the Company issued a warrant to a strategic
partner for a maximum of 2,666,666 shares of the Company's Series B Preferred
Stock at a purchase price of $1.50 per share. The actual number of shares
purchasable under the warrant is equal to the quotient of the amount in excess
of a specified dollar amount the Company receives in a specified one-year
period pursuant to the agreement between the Company and this strategic partner
divided by $0.75, and in any event may not exceed 2,666,666 shares. The
specified one-year period begins on the earlier of March 1, 2000 and the date
one which a certain threshold is reached pursuant to the agreement between the
Company and this strategic partner. The warrant terminates on the earlier of
April 27, 2004 and the consummation of a merger or acquisition of the Company
occurring after the specified one-year period. The Company is valuing the
warrant at its fair value, which at September 30, 1999 is zero. The fair value
of the warrant will be adjusted, as events occur, until completion of
performance. Costs resulting from the warrant, if any, will be recognized based
on increases in the fair value of the warrant.

Lease Commitment--In July, 1999 the Company entered into a facility lease
agreement for its corporate headquarters with minimum lease payments
approximating $2.4 million over five years.

Stock Split--On August 6, 1999 the Board of Directors approved a 2 for 1
split of the Company's Common and Preferred Stock and an increase in the number
of authorized Common Stock shares to 60,000,000 and authorized Preferred Stock
shares to 21,786,688. Accordingly, the share information in the accompanying
financial statements and footnotes have been restated to reflect the stock
split.

Finance Agreement--On August 20, 1999, the Company entered into a Loan and
Security Agreement with a bank for $2,950,000 of which $2.5 million is
available for equipment purchases through February 19, 2003 and $450,000 is
available through a revolving line maturing on August 19, 2000. Advances are
collateralized by substantially all assets of the Company. Interest on
borrowings are at the bank's prime rate plus 0.5%. Borrowings for equipment
purchases are payable in 30 equal monthly installments beginning March 19,
2000.

In connection with the agreement, the Company issued a Common Stock purchase
warrant which permits the holder to purchase up to 10,000 shares of the
Company's Common Stock at a purchase price of the lesser of $2.50 per share and
the price per share received by the Company in the next round of financing. The
warrant is exercisable only (i) after the Company's initial public offering,
(ii) immediately prior to a change in control and (iii) with the written
consent of the Company. The Company has valued the warrant at fair value,
approximately $20,000 at September 30, 1999. The cost associated with the
warrant has been deferred and will be recognized over the period of the finance
agreement.

Proposed Merger Agreement--In October 1999, the Company entered into a
merger agreement with Stamps.com, Inc. a development stage enterprise
developing an Internet-based postage service for end-users. In connection with
the proposed merger, the Company will receive an aggregate 8 million shares of
Stamps.com Common Stock in exchange for all the outstanding Common and
Preferred Stock, and outstanding options and warrants of the Company. The
agreement is subject to shareholder approval by both companies and regulatory

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

On October 22, 1999, Stamps.com entered into a merger agreement to acquire
iShip.com in exchange for up to 8,000,000 shares of Stamp.com's common stock.
Stamps.com's management has prepared the following unaudited pro forma
condensed combined financial information to give effect to this acquisition.
The Unaudited Pro Forma Condensed Combined Statements of Operations for the
year ended December 31, 1998 and for the nine months ended September 30, 1999
give effect to the iShip.com acquisition as if it had taken place on January 1,
1998. The Unaudited Pro Forma Condensed Combined Balance Sheet as of September
30, 1999 gives effect to the iShip.com acquisition as if it had taken place on
such date.

The pro forma adjustments, which are based upon available information and
certain assumptions that Stamps.com believes are reasonable in the
circumstances, are applied to the historical financial statements of Stamps.com
and iShip.com. The iShip.com acquisition will be accounted for using the
purchase method of accounting. Stamps.com allocation of purchase price is based
upon management's current estimates of the fair value of assets acquired and
liabilities assumed in accordance with Accounting Principles Board No. 16.

The purchase price allocations reflected in the accompanying unaudited pro
forma condensed combined financial statements may be different from the final
allocation of the purchase price and such differences may be material. The
Company expects to complete a valuation and other procedures during the first
quarter of 2000.

As part of the merger agreement, both companies have agreed to deposit
800,000 shares of Stamps.com common stock that would have been exchanged at the
close of this transaction into an escrow account immediately preceeding the
close of this transaction. The escrow amount is intended to compensate
Stamps.com for any inaccuracy or breach of any representation, warranty,
covenant or agreement of iShip.com 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 accompanying unaudited pro forma condensed combined financial
information should be read in conjunction with the historical financial
statements and the notes thereto for both Stamps.com and iShip.com, which are
included elsewhere in this prospectus. The unaudited pro forma condensed
combined financial information is provided for informational purposes only and
does not purport to represent what Stamps.com's financial position or results
of operations would actually have been had the iShip.com acquisition occurred
on such dates or to project Stamps.com's results of operations or financial
position for any future period.

NOTES TO UNAUDITED PRO FORMA CONDENSED
COMBINED FINANCIAL INFORMATION

The pro forma financial information gives effect to the following pro forma
adjustments:

The iShip.com merger will be accounted for using the purchase method of
accounting. In connection with the acquisition, Stamps.com will issue up to 8
million shares of Common Stock in exchange for all of the outstanding shares of
iShip.com capital stock, options and warrants. For purposes of these pro forma
financial statements, the estimated purchase price is approximately $310.3
million based on $43.10 per share and the issuance of 7.2 million shares of
common stock (8 million less the escrow amount of 800,000). The $43.10 per
share amount is the average of the last reported sale price of our Common Stock
on the Nasdaq National Market for the six trading days before and after October
25, 1999, the date we announced the Merger.

The iShip.com shares were first converted to Stamps.com equivalent shares by
taking the number of iShip.com shares over the total number of iShip.com shares
multiplied by 8,000,000 to arrive at Stamps.com shares for each iShip.com
share. This calculation has been made for purposes of these financial
statements only and does not represent the final exchange ratio, which will be
determined on the third trading day prior to the closing of the transaction.

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

Unvested stock options................... 1,700 381 16,432
------ ----- --------
32,105 7,200 $310,320
====== ===== ========
</TABLE>

The fair value of "shares" was calculated by taking the value of the
Stamps.com shares ($43.10 per share) times the number of Stamps.com shares to
be exchanged.

With respect to stock options exchanged as part of the iShip.com merger, all
vested and unvested iShip.com options exchanged for Stamps.com options are
included as part of the purchase price based on their fair value. The fair
value of the shares underlying options and warrants was calculated by taking
the vested and unvested options and warrants to purchase Stamps.com shares
(1,289,000 options) times the fair value of the stock ($43.10 per share).
Proceeds to be received from the option and warrant holders upon exercise were
excluded as the amounts are immaterial.

The pro forma financial information has been prepared on the basis of
assumptions described in these notes and include assumptions relating to the
allocation of the consideration paid for the assets and liabilities of
iShip.com based on preliminary estimates of their fair value. The actual
allocation of such consideration may differ from that reflected in the pro
forma financial information after valuations and other procedures to be
performed after the closing of the iShip.com acquisition.

iShip.com merger principally include accounts payable, accrued payroll and
long-term debt.

2. The pro forma adjustment is for goodwill allocation of $288.76 million.

3. The pro forma adjustment is for deferred stock compensation associated
with the unvested iShip.com stock options to acquire approximately 1.7 million
shares of iShip.com common stock to be assumed by Stamps.com.

4. The pro forma adjustment to "shareholders' equity" reflects the
elimination of iShip.com's shareholders' equity ($5.1 million) and the impact
of the issuance of Stamps.com's common stock ($310.3 million) in connection
with the iShip.com merger.

5. The pro forma adjustment is for amortization of deferred stock
compensation associated with the unvested iShip.com stock options assumed by
Stamps.com over the remaining vesting period of $4.1 million and amortization
of goodwill of $72.2 million for the year ended December 31, 1998.

6. The pro forma adjustment is for amortization of deferred stock
compensation of $3.1 million and amortization of goodwill of $54.1 million for
the nine months ended September 30, 1999.

A. The Boards of Directors of each of the Parent, Merger Sub and the Company

will become exercisable for Parent Common Stock, subject to the terms and
conditions set forth herein.

<PAGE>

1.2 Effective Time. Unless this Agreement is earlier terminated pursuant to
Section 8.1, the closing of the Merger (the "Closing") will take place as
promptly as practicable, but no later than five Business Days following
satisfaction or waiver of the conditions set forth in Article 6, at the offices
of Brobeck, Phleger & Harrison LLP, 38 Technology Drive, Irvine, California,
unless another place or time is agreed to by the Parent and the Company. The
date upon which the Closing actually occurs is herein referred to as the
"Closing Date." On the Closing Date, the parties hereto shall cause the Merger
to be consummated by filing Articles of Merger (or like instrument), in
substantially the form attached hereto as Exhibit B (the "Articles of Merger"),
with the Secretary of State of the State of Washington, in accordance with
applicable Laws (the date and time of acceptance by the Secretary of State of
the State of Washington of such filing, or such later time agreed to by the
parties and set forth in the Articles of Merger, being referred to herein as
the "Effective Time").

1.3 Effect of the Merger on Constituent Corporations. At the Effective Time,
the Merger shall have the effects provided for in the applicable provisions of
the Washington Code. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time, all the property, rights, privileges,
powers and franchises of Merger Sub and the Company shall vest in the Surviving
Corporation, and all debts, liabilities, obligations, restrictions,
disabilities and duties of Merger Sub and the Company shall become the debts,
liabilities, obligations, restrictions, disabilities and duties of the
Surviving Corporation.

1.4 Articles of Incorporation and Bylaws of Surviving Corporation.

(a) At the Effective Time, the articles of incorporation of Merger Sub, as
in effect immediately prior to the Effective Time, shall be the articles of
incorporation of the Surviving Corporation until thereafter amended as provided
by law and such articles of incorporation and bylaws of the Surviving
Corporation, except that Article I thereof shall be amended to read in its
entirety as follows: "The name of the Corporation is iShip.com, Inc."

(b) The bylaws of Merger Sub, as in effect immediately prior to the
Effective Time, shall be the bylaws of the Surviving Corporation until
thereafter amended as provided by such bylaws, the articles of incorporation

(including Parent Common Stock to be reserved for issuance upon exercise of any
of the Company Options or Company Warrants to be assumed by the Parent as
provided herein) in the Merger and in exchange for all vested and unvested
Company Options and Company Warrants shall be the Aggregate Merger Share
Number. No increase shall be made in the number of shares of Parent Common
Stock issuable as a result of the transactions contemplated by this Agreement
arising from any consideration (except for deemed share consideration arising
from the net exercise provisions of any Company Options or Company Warrants,
which share consideration shall continue to be outstanding shares of Company

<PAGE>

(b) Subject to the terms and conditions of this Agreement, as of the
Effective Time, by virtue of the Merger and without any action on the part of
the Parent or Merger Sub, the Company or the holder of any shares of the
Company Capital Stock and Company Options or Company Warrants, the following
shall occur:

(i) Conversion of Company Common Stock. At the Effective Time, each
share of Company Common Stock issued and outstanding immediately prior to
the Effective Time (other than any shares of Company Common Stock to be
canceled pursuant to Section 1.6(b)(iv) and any Dissenting Shares (as
provided in Section 1.7)) will be converted automatically into the right to
receive that number of shares of Parent Common Stock equal to the Common
Stock Exchange Ratio, rounded down to the nearest whole share of Parent
Common Stock.

(ii) Conversion of Series A Preferred Stock. At the Effective Time, each
share of Company Series A Preferred Stock issued and outstanding
immediately prior to the Effective Time (other than any shares of Company
Series A Preferred Stock to be cancelled pursuant to Section 1.6(b)(iv) and
any Dissenting Shares (as provided in Section 1.7)) will be automatically
converted into the right to receive that number of shares of Parent Common
Stock equal to the Series A Exchange Ratio, rounded down to the nearest
whole share of Parent Common Stock.

(iii) Conversion of Series B Preferred Stock. At the Effective Time,
each share of Company Series B Preferred Stock issued and outstanding
immediately prior to the Effective Time (other than any shares of Company
Series B Preferred Stock to be cancelled pursuant to Section 1.6(b)(iv) and
any Dissenting Shares (as provided in Section 1.7)) will be automatically
converted into the right to receive that number of shares of Parent Common
Stock equal to the Series B Exchange Ratio, rounded down to the nearest
whole share of Parent Common Stock.

(iv) Cancellation of Parent-Owned and Company-Owned Stock. Each share of
Company Capital Stock owned by the Parent or the Company or any Subsidiary
of the Parent or the Company immediately prior to the Effective Time shall
be automatically canceled and extinguished without any consideration in
respect thereof and without any further action on the part of the Parent,
Merger Sub or the Company.

(v) Company Options and Stock Plan. At the Effective Time all unexpired
and unexercised Company Options and Company Warrants then outstanding,
whether vested or unvested, together with the Company's Amended and
Restated 1997 Stock Plan (the "Stock Plan"), shall be assumed by the Parent
in accordance with provisions described below.

(A) At the Effective Time, each unexpired and unexercised Company
Option and Company Warrant then outstanding, whether vested or
unvested, together with the Stock Plan, shall be, in connection with
the Merger, assumed by the Parent. Each Company Option and Company
Warrant so assumed by the Parent under this Agreement shall continue to
have, and be subject to, the same terms and conditions as were
applicable to such Company Option or Company Warrant immediately prior
to the Effective Time; provided that (1) such Company Option or Company
Warrant, as the case may be, shall be exercisable for that number of
whole shares of Parent Common Stock equal to the product of the number
of shares of Company Capital Stock that were issuable upon exercise of
such Company Option or Company Warrant immediately prior to the
Effective Time multiplied by the Exchange Ratio applicable to the
series or class of Company Capital Stock subject to the Company Option
or Company Warrant (rounded down to the nearest whole number of shares
of Parent Common Stock) and (2) the per share exercise price for the
shares of Parent Common Stock issuable upon exercise of such assumed
Company Option or Company Warrant, as the case may be, shall be equal
to the quotient determined by dividing the exercise price per share of
Company Capital Stock at which such Company Option or Company Warrant
was exercisable immediately prior to the Effective Time by the Exchange
Ratio applicable to the series or class of Company Capital Stock
subject to the Company Option or Company Warrant (rounded up to the
nearest whole cent).

(B) It is the intention of the parties that the Company Options
assumed by the Parent shall qualify following the Effective Time as
incentive stock options as defined in Section 422 of the Code

A-7
<PAGE>

to the same extent the Company Options qualified as incentive stock
options immediately prior to the Effective Time and the provisions of
this Section 1.6(b)(v) shall be applied consistent with this intent.

(C) At the Effective Time, the Parent shall succeed to the Company's
rights and assume the Company's obligations under any Restricted Stock
Purchase Agreements. Any and all restrictions on the Company Restricted
Stock issued pursuant to the Stock Plan or such other agreements which
do not lapse in accordance with their terms as in effect on the date of
this Agreement shall continue in full force and effect until such
restrictions lapse pursuant to the terms of such agreements.

(D) Notwithstanding the foregoing, the Series B Preferred Stock
Purchase Warrant, dated April 27, 1999 (the "MBE Warrant"), by and
between the Company and Mail Boxes Etc. USA, Inc. ("MBE"), shall,
subject to the consent of MBE, be modified, at the Effective Time, to
be a warrant of the Parent on terms and subject to conditions identical
to the MBE Warrant, except that such warrant shall be exercisable for
the number of whole shares of Parent Common Stock equal to the product
of the number of shares of Series B Preferred Stock that were issuable
upon exercise of the MBE Warrant immediately prior to the Effective
Time multiplied by the Series B Exchange Ratio (rounded down to the
nearest whole number of shares of Parent Common Stock) and the per
share exercise price for the shares of Parent Common Stock issuable
upon exercise of such warrant shall be equal to the quotient determined
by dividing the exercise price per share of Series B Preferred Stock
under the MBE Warrant by the Series B Exchange Ratio (rounded up to the
nearest whole cent).

(vi) Adjustments to Exchange Ratios. The Exchange Ratios shall be
equitably adjusted to reflect fully the effect of any stock split, reverse
split, stock combination, stock dividend (including any dividend or
distribution of securities convertible into Parent Common Stock or Company
Capital Stock), reorganization, reclassification, recapitalization or other
like change with respect to Parent Common Stock or Company Capital Stock
occurring on or after the date hereof and prior to the Effective Time.

(vii) Capital Stock of Merger Sub. Each share of common stock, no par
value per share, of Merger Sub, issued and outstanding immediately prior to
the Effective Time shall be converted into and exchanged for one validly
issued, fully paid and nonassessable share of common stock, no par value
per share, of the Surviving Corporation. Each share certificate of Merger
Sub evidencing ownership of any such shares shall continue to evidence
ownership of such shares of capital stock of the Surviving Corporation.

1.7 Dissenting Shares.

(a) Notwithstanding any provision of this Agreement to the contrary, any
shares of Company Capital Stock held by a holder who has demanded and perfected
dissenters' rights for such shares in accordance with Washington Code and who,
as of the Effective Time, has not effectively withdrawn or lost such
dissenters' rights ("Dissenting Shares") shall not be converted into or
represent a right to receive shares of Parent Common Stock pursuant to Section
1.6, but the holder thereof shall only be entitled to such rights as are
granted by the Washington Code.

(b) Notwithstanding the provisions of subsection (a) above, if any holder of
shares of Company Capital Stock who demands purchase of such shares under the
Washington Code shall effectively withdraw or lose (through failure to perfect
or otherwise) such holder's dissenters' rights, then, as of the later of (i)
the Effective Time or (ii) the occurrence of such withdrawal or loss, such
holder's shares shall automatically be converted into and represent only the
right to receive shares of Parent Common Stock as provided in Section 1.6,
without interest thereon, upon surrender of the certificate representing such
shares.

(c) The Company shall give the Parent (i) prompt notice of its receipt of
any written demands for appraisal of any shares of Company Capital Stock,
withdrawals of such demands, and any other instruments relating to the Merger
served pursuant to the Washington Code and received by the Company and (ii) the
opportunity to participate in all negotiations and proceedings with respect to
demands for appraisal of any shares of Company Capital Stock under the
Washington Code. The Company shall not, except with the prior written consent
of the Parent or as may be required under applicable law, voluntarily make any
payment with respect to any demands for appraisal of Company Capital Stock or
offer to settle or settle any such demands.

1.8 Exchange Procedures.

(a) Parent Common Stock. On the Closing Date, the Parent shall issue in
accordance with this Article 1, the aggregate number of shares of Parent Common
Stock issuable in exchange for outstanding shares of Company Capital Stock;
provided, however, that, on behalf of the holders of Company Capital Stock, the
Parent shall deposit into an escrow account a number of shares of Parent Common
Stock equal to the Escrow Amount. The portion of the Escrow Amount contributed
on behalf of each holder of Company Capital Stock shall be in proportion to the
aggregate number of shares of Parent Common Stock which such holder would
otherwise be entitled to receive by virtue of ownership of outstanding shares
of Company Capital Stock.

(b) Exchange Procedures. At the Closing, each holder of record of a
certificate or certificates (the "Certificates") which immediately prior to the
Effective Time represented outstanding shares of Company Capital Stock and
which shares were converted into the right to receive shares of Parent Common
Stock pursuant to Section 1.6, shall deliver the Certificates to the Parent.
Upon surrender of a Certificate for cancellation and a stock power indorsed in
blank with respect to the shares held pursuant to Article 7, the Parent shall
deliver to the holder of such Certificate in exchange therefor a certificate
representing the number of whole shares of Parent Common Stock (less the number
of shares of Parent Common Stock to be deposited in the Escrow Fund on such
holder's behalf pursuant to Article 7 hereof), to which such holder is entitled
pursuant to Section 1.6, and the Certificate so surrendered shall be canceled.
As soon as practicable after the Effective Time, and subject to and in
accordance with the provisions of Article 7 hereof, the Parent shall cause to
be distributed to the Depositary a certificate or certificates (in such
denominations as may be requested by the Depositary), registered in the name of
each former shareholder of the Company, representing that number of shares of
Parent Common Stock equal to the Escrow Amount. Such shares shall be
beneficially owned by the holders on whose behalf such shares were deposited in
the Escrow Fund and shall be available to compensate the Parent as provided in
Article 7. Until surrendered, each outstanding Certificate will be deemed, from
and after the Effective Time, for all corporate purposes, other than the
payment of dividends, to evidence the ownership of the number of full shares of
Parent Common Stock into which such shares of Company Capital Stock shall have
been so converted.

(c) Distributions With Respect to Unexchanged Shares of Company Capital
Stock. No dividends or other distributions with respect to Parent Common Stock
declared or made after the Effective Time and with a record date after the
Effective Time will be paid to the holder of any unsurrendered Certificate with
respect to the shares of Parent Common Stock represented thereby until the
holder of record of such Certificate shall surrender such Certificate. Subject
to applicable law, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of
Parent Common Stock issued in exchange for any such unsurrendered Certificates,
without interest, at the time of such surrender, the amount of dividends or
other distributions with a record date after the Effective Time theretofore
payable with respect to such shares of Parent Common Stock.

(d) Transfers of Ownership. If any certificate for shares of Parent Common
Stock is to be issued pursuant to the Merger in a name other than that in which
the Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to the Parent, or any agent designated
by it, any transfer or other taxes required by reason of the issuance of a
certificate for shares of Parent Common Stock in any name other than that of
the registered holder of the Certificate surrendered, or established to the
satisfaction of the Parent or any agent designated by it that such tax has been
paid or is not payable.

1.9 No Further Ownership Rights in Company Capital Stock. All shares of
Parent Common Stock issued upon the surrender for exchange of shares of Company
Capital Stock in accordance with the terms hereof shall be deemed to have been
issued in full satisfaction of all rights pertaining to such shares of Company
Capital Stock, and there shall be no further registration of transfers on the
records of the Company of shares of Company Capital Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article 1.

A-9
<PAGE>

1.10 Lost, Stolen or Destroyed Certificates. In the event any certificates
evidencing shares of Company Capital Stock shall have been lost, stolen or
destroyed, the Parent shall issue certificates representing such shares of
Parent Common Stock in exchange for such lost, stolen or destroyed
Certificates, upon the making of an affidavit of that fact by the holder
thereof; provided, however, that the Parent may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed Certificates to provide an indemnity or deliver a bond in
such sum as it may reasonably direct as indemnity against any claim that may be
made against the Parent with respect to the Certificates alleged to have been
lost, stolen or destroyed.

a material adverse effect on the Business or Condition of the Company. Section
2.1 of the Disclosure Letter sets forth each jurisdiction where the Company is
so qualified, licensed or admitted to do business and separately lists each
other jurisdiction in which the Company owns, uses, licenses or leases its

hereunder, have been duly and validly authorized by all necessary action by the
Board of Directors of the Company, and no other action on the part of the Board

executed and delivered by the Company and, assuming the due authorization,
execution and delivery hereof by Parent and Merger Sub, constitutes a legal,
valid and binding obligation of the Company enforceable against the Company in

moratorium or other similar Laws relating to the enforcement of creditors'
rights generally and by general principles of equity.

2.3 Capital Stock.

the date of the Interim Financial Statements and in accordance with the
provisions of this Agreement which, individually and in the aggregate, are not
material to the Business or Condition of the Company, and are not for tort or
for breach of contract.

2.10 Taxes.

(a) All Tax Returns required to have been filed by or with respect to the
Company or any affiliated, consolidated, combined, unitary or similar group of
which the Company is or was a member (a "Relevant Group") have been duly and
timely filed (including any extensions), and each such Tax Return correctly and
completely reflects Tax liability and all other material information required
to be reported thereon. All Taxes due and payable by the Company or any member
of a Relevant Group, whether or not shown on any Tax Return, or claimed to be
due by any Tax Authority, have been paid or accrued on the Company Financials
for all periods (or portions thereof) through and including the date thereof.
All such Tax Returns are true, complete and correct in all material respects.

(b) The Company has not incurred any material liability for Taxes other than
as reflected on the Interim Financial Statements for all periods (or portions
thereof) through and including the date thereof and will not incur additional
Liabilities for Taxes through and including the Closing Date, other than in the

the most recent fiscal month end, exceed by any material amount the reserve for
liability for Income Tax (other than the reserve for deferred taxes established

face of the Company's most recent balance sheet and (ii) will not exceed by any
material amount that reserve as adjusted for operations and transactions
through the Closing Date.

of any jurisdiction in which the Company does not file Tax Returns that it is
or may be subject to taxation by that jurisdiction.

(d) The Company has withheld and paid all Taxes required to have been
withheld and paid in connection with amounts paid or owing to any employee,
creditor or independent contractor.

(e) The Company does not have knowledge of any actions by any Taxing
Authority in connection with assessing additional Taxes against or in respect
of it for any past period. There is no dispute or claim concerning any Tax
liability of the Company either (i) threatened, claimed or raised by any Taxing
Authority or (ii) of which the Company is aware. There are no Liens for Taxes
upon the Assets and Properties of the Company other than Liens for Taxes not
yet due. Section 2.10 of the Disclosure Letter indicates those Tax Returns, if
any, of the Company that have been audited or examined by Taxing Authorities,
and indicates those Tax Returns of the Company that currently are the subject
of audit or examination. The Company has delivered to the Parent complete and
correct copies of all federal, state, local and foreign income Tax Returns
filed by, and all Tax examination reports and statements of deficiencies
assessed against or agreed to by, the Company since the fiscal year ended
December 31, 1997.

(f) There are no outstanding agreements or waivers extending the statutory
period of limitation applicable to any Tax Returns required to be filed by, or
which include or are treated as including, the Company or with respect to any
Tax assessment or deficiency affecting the Company or any Relevant Group.

provision of state, local or foreign Law), (ii) as a transferee or successor,
(iii) by Contract or (iv) otherwise.

(j) The Company is not a party to or bound by any obligations under any tax
sharing, tax allocation, tax indemnity or similar agreement or arrangement.

(k) The Company is not involved in, subject to, or a party to any joint
venture, partnership, Contract or other arrangement that is treated as a
partnership for federal, state, local or foreign Income Tax purposes.

(l) The Company was not included and is not includible in the Tax Return of
any Relevant Group with any corporation other than such a return of which the
Company is the common parent corporation.

(m) The Company has not made any payments, is not obligated to make any
payments, nor is a party to any Contract that under certain circumstances could
require it to make any payments that are not deductible as a result of the
provisions set forth in Section 280G of the Code or the treasury regulations
thereunder or would result in an excise tax to the recipient of any such
payment under Section 4999 of the Code (other than payments for which
shareholder approval meeting the requirements of Section 280G(c)(5) of the Code
will be obtained prior to the Closing Date).

(n) The Company is not nor has it ever been a United States real property
holding corporation within the meaning of Section 897(c)(1)(A)(ii) of the Code.

2.11 Legal Proceedings.

affecting the Company or any of its Assets and Properties since the Company's
inception and prior to the date hereof.

2.12 Compliance with Laws and Orders. The Company has not violated, and is
not currently in default under, any Law or Order applicable to the Company or
any of its Assets and Properties, except for any such violations or defaults
that could not reasonably be expected to have a material adverse effect on the
Business or Condition of the Company.

2.13 Plans; ERISA.

(a) For purposes of this Agreement, the term "Plans" shall mean (i) all
"employee benefit plans" (as such term is defined in Section 3(3) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), of which
any of the Company or any member of the same controlled group of businesses as
the Company within the meaning of Section 4001(a)(14) of ERISA (an "ERISA
Affiliate") is or ever was a sponsor

A-16
<PAGE>

or participating employer or as to which the Company or any of its ERISA
Affiliates makes contributions or is or has been required to make
contributions, and (ii) any similar employment, severance or other arrangement
or policy of any of the Company or any of its ERISA Affiliates (whether written
or oral) providing for health, life, vision or dental insurance coverage
(including self-insured arrangements), workers' compensation, disability
benefits, supplemental unemployment benefits, vacation benefits or retirement
benefits, fringe benefits, or for profit sharing, deferred compensation,
bonuses, stock options, stock appreciation or other forms of incentive
compensation or post-retirement insurance, compensation or benefits. Except as
disclosed on Section 2.13 of the Disclosure Letter, (i) neither the Company nor
any of its ERISA Affiliates maintains or sponsors (or ever maintained or
sponsored), or makes or is required to make contributions to, any Plans, (ii)
none of the Plans is or was a "multi-employer plan", as defined in Section
3(37) of ERISA, (iii) none of the Plans is or was a "defined benefit pension
plan" within the meaning of Section 3(35) of ERISA, (iv) none of the Plans
provides or provided post-retirement medical or health benefits, other than as
required under applicable Laws, (v) none of the Plans is or was a "welfare
benefit fund," as defined in Section 419(e) of the Code, or an organization
described in Sections 501(c)(9) or 501(c)(20) of the Code, (vi) neither the
Company nor any of its ERISA Affiliates is or was a party to any collective
bargaining agreement and (vii) neither the Company nor any of its ERISA
Affiliates has announced or otherwise made any commitment to create or amend
any Plan (other than as required to comply with applicable Laws or to maintain
the qualified status of a Plan under Section 401(a) of the Code).
Notwithstanding any statement or indication in this Agreement to the contrary,
there are no Plans (a) as to which the Parent will be required to make any
contributions or with respect to which the Parent shall have any obligation or
liability whatsoever, whether on behalf of any of the current employees of the
Company or on behalf of any other Person, after the Closing (other than current
deferred contributions to the Company's 401(k) plan and the current month's
premium for health plan coverage), or (b) which the Parent or the Surviving
Corporation will not be able to terminate immediately after the Closing in
accordance with their terms, ERISA and the Code. With respect to each of such
Plans, at the Closing there will be no unrecorded liabilities with respect to
the establishment, implementation, operation, administration or termination of
any such Plan, or the termination of the participation in any such Plan by the
Company or its ERISA Affiliates. The Company has delivered to the Parent true
and complete copies of: (i) each of the Plans and any related funding
agreements thereto (including insurance contracts) including all amendments,
all of which are legally valid and binding and in full force and effect and
there are no defaults thereunder, (ii) the currently effective Summary Plan
Description pertaining to each of the Plans, (iii) the annual reports filed for
each of the Plans since inception (including all related schedules), if
applicable, (iv) the most recently filed PBGC Form 1 (if applicable), (v) the
most recent Internal Revenue Service determination letter for each Plan which
is intended to constitute a qualified plan under Section 401 of the Code and
each amendment to each of the foregoing documents and (vi) for each unfunded
Plan, if any, financial statements consisting of (A) the consolidated statement
of assets and liabilities of such Plan as of its most recent valuation date,
and (B) the statement of changes in fund balance and in financial position or
the statement of changes in net assets available for benefits under such Plan
for the most recently-ended plan year, which such financial statements shall
fairly present the financial condition and the results of operations of such
Plan in accordance with GAAP, consistently applied, as of such dates.

(b) The present value of all accrued benefits under any Plans subject to
Title IV of ERISA shall not, as of the Closing Date, exceed the value of the
assets of such Plans allocated to such accrued benefits, based upon the
applicable provisions of the Code and ERISA, and each such Plan shall be
capable of being terminated as of the Closing Date in a "standard termination"
under Section 4041(b) of ERISA. With respect to each Plan that is subject to
Title IV of ERISA, (i) no amount is due or owing from the Company or any of its
ERISA Affiliates to the PGBC or to any "multi-employer Plan" as defined in
Section 3(37) of ERISA on account of any withdrawal therefrom and (ii) no such
Plan has been terminated other than in accordance with ERISA or at a time when
the Plan was not sufficiently funded. The transactions contemplated hereunder,
including, without limitation, the termination of any Plan at or prior to the
Closing, shall not result in any such withdrawal or other liability under any
applicable Laws.

(c) Neither the Company nor any of its ERISA Affiliates is subject to any
material liability, tax or penalty whatsoever to any person or agency
whomsoever as a result of engaging in a prohibited transaction

A-17
<PAGE>

under ERISA or the Code, and neither the Company nor any of its ERISA
Affiliates has any knowledge of any circumstances which reasonably might result
in any material liability, tax or penalty, including, but not limited to, a
penalty under Section 502 of ERISA, as a result of a breach of any duty under
ERISA or under other Laws. Each Plan which is required to comply with the
provisions of Sections 4980B and 4980C of the Code, or with the requirements
referred to in Section 4980D of the Code, has complied in all material
respects. No event has occurred which could subject any Plan to Tax under
Section 511 of the Code. None of the Plans subject to Title IV of ERISA has
been completely or partially terminated nor has there been any "reportable
event," as such term is defined in Section 4043(b) of ERISA, with respect to
any of the Plans since the effective date of ERISA nor has any notice of intent
to terminate been filed or given with respect to any such Plan. There has been
no (i) withdrawal by the Company or any of its ERISA Affiliates that is a
substantial employer from a single-employer plan which is a Plan and which has
two or more contributing sponsors at least two of whom are not under common
control, as referred to in Section 4063(b) of ERISA, or (ii) cessation by the
Company or any of its ERISA Affiliates of operations at a facility causing more
than twenty percent of Plan participants to be separated from employment, as
referred to in Section 4062(f) of ERISA. Neither the Company nor any of its
ERISA Affiliates, nor any other organization of which any of them are a
successor or parent corporation as defined in Section 4069(b) of ERISA, have
engaged in any transaction described in Section 4069(a) of ERISA.

(d) None of the Plans nor any trust created thereunder has incurred any
"accumulated funding deficiency" as such term is defined in Section 412 of the
Code, whether or not waived, since the effective date of said Section 412, and
no condition has occurred or exists which by the passage of time could be
expected to result in an accumulated funding deficiency as of the last day of
the current plan year of any such Plan. Furthermore, neither the Company nor
any of its ERISA Affiliates has any unfunded liability under ERISA in respect
of any of the Plans (except with respect to current deferred contributions
under the Company's 401(k) plan and the current month's premium for health plan
coverage). Each of the Plans which is intended to be a qualified plan under
Section 401(a) of the Code has received a favorable determination letter from
the Internal Revenue Service or has time remaining to apply for a determination
letter and make such changes as may be required under the remedial amendment
period of Section 401(b) of the Code. Each Plan has been operated in accordance
with its terms and with the provisions of the Code. All of the Plans have been
administered and maintained in compliance with ERISA, the Code and all other
applicable Laws, except as could not have a material adverse effect on the
Business or Condition of the Company. All contributions required to be made to
each of the Plans under the terms of that Plan, ERISA, the Code or any other
applicable Laws have been timely made. Each Plan intended to meet the
requirements for tax-favored treatment under Subchapter B of Chapter 1 of the
Code meet such requirements. There are no Liens against the property of the
Company or any of its ERISA Affiliates under Section 412(n) of the Code or
Section 302(f) or 4068 of ERISA. The Interim Financial Statements properly
reflect all amounts required to be accrued as liabilities to date under each of
the Plans. There is no contract, agreement or benefit arrangement covering any
employee of the Company or any Subsidiary which, individually or collectively,
could give rise to the payment of any amount which would constitute an "excess
parachute payment" (as defined in Section 280G of the Code) (other than
payments for which shareholder approval meeting the requirements of Section
280G(c)(5) of the Code will be obtained prior to the Closing Date). Except as
disclosed in Section 2.13(d) of the Disclosure Letter, the execution and
performance of this Agreement will not (i) result in any obligation or
liability (with respect to accrued benefits or otherwise) of the Parent or the
Surviving Corporation to the PBGC, any Plan, or any present or former employee
of the Parent or the Surviving Corporation, (ii) be a trigger event under any
Plan that will result in any payment (whether of severance pay or otherwise)
becoming due to any present or former employee, officer, director, shareholder,
contractor, or consultant, or any of their dependents, or (iii) accelerate the
time of payment or vesting, or increase the amount, of compensation due to any
employee, officer, director, shareholder, contractor, or consultant of the
Company (except as required in connection with any termination or partial
termination of a qualified Plan and except for acceleration of options under
the Stock Plan and accelerated lapsing of repurchase rights under Company
Common Stock purchase agreements). With respect to any insurance policy which
provides, or has provided, funding for benefits under any Plan, (i) there is
and will be no liability of the Company or the Parent in the nature of a
retroactive or retrospective rate adjustment, loss sharing arrangement, or
actual or contingent liability as of the Closing Date, nor would there be any
such

A-18
<PAGE>

liability if such insurance policy were terminated as of the Closing Date, and
(ii) no insurance company issuing any such policy is in receivership,
conservatorship, bankruptcy, liquidation, or similar proceeding, and, to the
knowledge of the Company, no such proceedings with respect to any insurer are
imminent.

(e) Other than routine claims for benefits under the Plans, there are no
pending, or, to the best knowledge of the Company, threatened, Actions or
Proceedings involving the Plans, or the fiduciaries, administrators, or
trustees of any of the Plans or the Company or any of its ERISA Affiliates as
the employer or sponsor under any Plan, with any of the IRS, the Department of
Labor, the PBGC, any participant in or beneficiary of any Plan or any other
person whomsoever. The Company knows of no reasonable basis for any such claim,
lawsuit, dispute, action or controversy.

2.14 Title to Property. The Company has good and marketable title to all of
its properties, interests in properties and assets, real and personal,
reflected in the Company Financials or acquired after the Financial Statement
Date (except properties, interests in properties and assets sold or otherwise
disposed of since the Financial Statement Date in the ordinary course of
business), or with respect to leased properties and assets, valid leasehold
interests in, free and clear of all mortgages, liens, pledges, charges or
encumbrances of any kind or character, except (i) the lien of current taxes not
yet due and payable, (ii) such imperfections of title, liens and easements as
do not and will not materially detract from or interfere with the use of the
properties subject thereto or affected thereby, or otherwise materially impair
business operations involving such properties and (iii) liens securing debt
which is reflected on the Company Financials. The plants, property and
equipment of Company that are used in the operations of its business are in
good operating condition and repair, subject to normal wear and tear. All
properties used as of the applicable date in the operations of Company are
reflected in the Company Financials to the extent generally accepted accounting
principles require the same to be reflected.

2.15 Intellectual Property.

(a) Section 2.15(a) of the Disclosure Letter lists all Company Registered
Intellectual Property and lists any proceedings or actions pending as of the
date hereof before any court, tribunal (including the PTO or equivalent
authority anywhere in the world) related to any of the Company Registered

(b) Each item of Company Intellectual Property, including all Company

(c) To the extent that any Company Intellectual Property has been developed
or created by any Person other than the Company, the Company has a written
agreement with such Person with respect thereto and the Company has either (i)

Property by operation of law or by valid assignment of any such rights or (ii)

(d) Except pursuant to agreements listed in Section 2.15(d) of the

expected to have a material adverse effect on the Parent and its subsidiaries,
taken as a whole.

3.9 Tax Matters. Neither the Parent nor any of its subsidiaries nor, to the
knowledge of the Parent, any of their respective Affiliates or agents is aware
of any agreement, plan or other circumstance that would prevent the Merger from
constituting a reorganization under Section 368(a) of the Code.

3.10 Intellectual Property Rights. Except as otherwise described in the
Parent's SEC Documents: (a) the Parent owns or possesses adequate rights to use
all patents, patent rights or licenses, inventions, collaborative research
agreements, trade secrets, know-how, trademarks, service marks, trade names and
copyrights which are necessary to conduct its businesses as currently
conducted, (b) the expiration of any patents, patent rights, trade secrets,
trademarks, service marks, trade names or copyrights would not reasonably be
expected to result in a material adverse effect on the Parent and its
subsidiaries, taken as a whole, (c) the Parent has not received any notice of,
and has no knowledge of, any infringement of or conflict with asserted rights
of the Parent by others with respect to any patent, patent rights, inventions,
trade secrets, know-how, trademarks, service marks, trade names or copyrights
and (d) the Parent has not received any notice of, and has no knowledge of, any
infringement of or conflict with asserted rights of others with respect to any
patent, patent rights, inventions, trade secrets, know-how, trademarks, service
marks, trade names or copyrights which, singly or in the aggregate, if the
subject of an unfavorable decision, ruling or finding, would reasonably be
expected to have a material adverse effect on the Parent and its subsidiaries,
taken as a whole. Except as otherwise disclosed in the Parent's SEC Documents,
there is no claim being made against the Parent regarding patents, patent
rights or licenses, inventions, collaborative research, trade secrets, know-
how, trademarks, service marks, trade names or copyrights. Except as otherwise
disclosed in the Parent's SEC Documents, the Parent, to its knowledge, does not
in the current conduct of its business nor as or currently proposed to be
conducted infringe or conflict with any right or patent of any third party, or

expected to result in any material adverse effect on the Parent and its
subsidiaries, taken as a whole, or that would reasonably be expected to
materially affect their Assets or Properties. To the Parent's knowledge, all
internal computer systems and each Constituent Component of those systems and
all computer-related products and each Constituent Component of those products
of the Parent fully comply with Year 2000 Qualification Requirements. "Year
2000 Qualification Requirements" means that the internal computer systems and
each Constituent Component of those systems and all computer-related products
and each Constituent Component of those products of the Parent (i) have been
reviewed to confirm that they store, process (including sorting and performing
mathematical operations, calculations and computations), input and output data
containing date and information correctly regardless of whether the date
contains dates and times before, on or after January 1, 2000, (ii) have been
designated to ensure date and time entry recognition and calculations, and date
data interface values that reflect the century, (iii) accurately manage and
manipulate data involving dates and times, including single century formulas
and multi-century formulas, and will not cause an abnormal ending scenario
within the application or generate incorrect values or invalid results
involving such dates, (iv) accurately process any date rollover and (v) accept
and respond to two-digit year date input in a manner that resolves any
ambiguities as to the century. "Constituent Component" means all software
(including operating systems, programs, packages and utilities), firmware,
hardware, networking components, and peripherals provided as part of the
configuration. The Parent has inquired of material vendors as to their
preparedness for the Year 2000 and has disclosed in the Parent's SEC Documents
any issues that would reasonably be expected to result in a material adverse
effect on the Parent and its subsidiaries, taken as a whole.

ARTICLE 4
CONDUCT PRIOR TO THE EFFECTIVE TIME

4.1 Conduct of Business of the Company. During the period from the date of
this Agreement and continuing until the earlier of the termination of this
Agreement and the Effective Time, the Company agrees (unless the Parent shall
give its prior consent in writing) to carry on its business in the ordinary
course consistent with past practice, to pay its Liabilities, including, but
not limited to, Taxes consistent with the Company's past practices, to pay or
perform other obligations when due consistent with the Company's past
practices, subject to any good faith disputes over such Liabilities and, to the
extent consistent with such business, to use reasonable efforts and institute
all policies to preserve intact its present business organization, keep
available the services of its present officers and key employees and preserve
its relationships with customers, suppliers, distributors, licensors,
licensees, independent contractors, shareholders and other Persons having
business dealings with it, all with the express purpose and intent of
preserving unimpaired its goodwill and ongoing businesses at the Effective
Time. Except as expressly contemplated by this Agreement and as set forth in
Section 4.1 of the Disclosure Letter, the Company shall not, without the prior
written consent of the Parent, take, or agree in writing or otherwise to take,
any of the actions described in Sections 2.9(a) through (ii) above, or any
other action that could make any of its representations or warranties contained
in this Agreement untrue or incorrect or prevent the Company from performing or
cause the Company not to perform its agreements and covenants hereunder.

4.2 No Solicitation. Until the earlier of the Effective Time and the date of
termination of this Agreement pursuant to the provisions of Section 8.1 hereof,
the Company will not (nor will the Company permit any of the Company's
officers, directors, shareholders, attorneys, investment advisors, agents,
representatives, Affiliates or Associates to) directly or indirectly, take any
of the following actions with any Person other than the Parent and its
designees: (a) solicit, initiate, entertain, review, or encourage any proposals
or offers from, or conduct discussions with or engage in negotiations with, any
Person relating to any possible Business Combination with the Company or any of
its Subsidiaries (whether such Subsidiaries are in existence on the date hereof
or are hereafter organized), (b) provide information with respect to the
Company to any Person, other than the Parent, relating to, or otherwise
cooperate with, facilitate or encourage any effort or attempt by any such
Person with regard to, any possible Business Combination with the Company or
any Subsidiary of the Company (whether such Subsidiaries are in existence on
the date hereof or are hereafter organized), (c) enter into a Contract with any
Person, other than the Parent, providing for a Business Combination with the
Company or any Subsidiary (whether such Subsidiaries are in existence on the
date hereof or are hereafter organized), or (d) make or authorize any
statement, recommendation or solicitation in support of any possible Business
Combination with the Company or any Subsidiary (whether such Subsidiary is in
existence on the date hereof or are hereafter organized) other than by the
Parent. Each of the foregoing provisions (a) through (d) shall be a "Triggering
Event." In addition to the foregoing, if the Company receives prior to the
Effective Time or the termination of this Agreement any offer or proposal
(formal or informal) relating to any of the above, the Company shall
immediately notify the Parent thereof and provide the Parent with the details
thereof including the identity of the Person or Persons making such offer or
proposal, and will keep the Parent fully informed of the status and details of
any such offer or proposal. Each of the Company and the Parent acknowledge that
this Section 4.2 was a significant inducement for the Parent to enter into this
Agreement and the absence of such provision would have resulted in either (i) a
material reduction in the merger consideration to be paid to the shareholders
of the Company or (ii) a failure to induce the Parent to enter into this
Agreement.

independent auditors to provide consents and comfort letters requested by the
Parent.

5.14 Takeover Statutes. If any Takeover Statute is or may become applicable
to the transactions contemplated hereby, the Board of Directors of the Company

SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND
AGREEMENTS; ESCROW PROVISIONS

7.1 Survival of Representations, Warranties, Covenants and
Agreements. Except as otherwise provided in Section 8.2, all of the
representations, warranties, covenants and agreements of the Company, Parent
and Merger Sub contained in this Agreement or in any instrument delivered
pursuant to this Agreement shall survive the Merger and continue until the
first anniversary of the Closing Date (the "Expiration Date").

7.2 Escrow Provisions.

(a) Establishment of the Escrow Fund. As soon as practicable after the
Effective Time, the Escrow Amount, without any act of any shareholder of the
Company, will be deposited with the Depositary (plus a proportionate share of
any additional shares of Parent Common Stock as may be issued upon any stock
splits, stock dividends or recapitalizations effected by the Parent following
the Effective Time), such deposit to constitute the Escrow Fund to be governed
by the terms set forth herein. The portion of the Escrow Amount contributed on
behalf of each shareholder of the Company shall be in proportion to the
aggregate number of shares of Parent Common Stock which such holder would
otherwise be entitled under Section 1.6.

(b) Recourse to the Escrow Fund. The Escrow Fund shall be available to
compensate the Parent and the Surviving Corporation, and their respective
officers, directors, employees, agents, Affiliates and Associates for any and
all Losses (whether or not involving a Third Party Claim), incurred or
sustained by the Parent or Merger Sub, their respective officers, directors,
employees, agents, Affiliates or Associates, directly or indirectly, as a
result of any inaccuracy or breach of any representation, warranty, covenant or
agreement of the Company contained herein or in any instrument delivered
pursuant to this Agreement. The Parent, Merger Sub and the Company each
acknowledge that such Losses, if any, would relate to unresolved contingencies
existing at the Effective Time, which if resolved at the Effective Time would
have led to a reduction in the aggregate Merger consideration to be paid to the
shareholders of the Company. The Escrow Fund shall be the sole post closing
remedy of the Parent and the Surviving Corporation for any breach of any
representation, warranty,

A-35
<PAGE>

agreement or covenant contained herein (other than claims for fraud or
negligent misrepresentation; provided, that no former shareholder of the
Company shall be liable to the Parent or the Surviving Corporation for acts of
fraud or negligent misrepresentation by Persons other than that former
shareholder of the Company ).

(c) Escrow Period; Distribution of Escrow Fund upon Termination of Escrow
Period. Subject to the following requirements, the Escrow Fund shall be in
existence immediately following the Effective Time and shall terminate at 5:00
p.m., Pacific Time, on the Expiration Date (the period of time from the
Effective Time through and including the Expiration Date is referred to herein
as the "Escrow Period"); and all shares of Parent Common Stock remaining in the
Escrow Fund shall be distributed as set forth in the last sentence of this
Section 7.2(c); provided, however, that the Escrow Period shall not terminate
with respect to such amount (or some portion thereof) that is necessary in the
reasonable judgment of the Parent, subject to the objection of the
Shareholders' Agent and the subsequent arbitration of the matter in the manner
as provided in Section 7.2(g) hereof, to satisfy any unsatisfied claims under
this Section 7.2 concerning facts and circumstances existing prior to the
termination of such Escrow Period which claims are specified in any Officer's
Certificate delivered to the Depositary prior to termination of such Escrow
Period. As soon as all such claims, if any, have been resolved, the Depositary
shall deliver to the former shareholders of the Company the remaining portion
of the Escrow Fund not required to satisfy such claims. Deliveries of shares of
Parent Common Stock remaining in the Escrow Fund to the former shareholders of
the Company pursuant to this Section 7.2(c) shall be made ratably in proportion
to their respective contributions to the Escrow Fund and the Parent shall use
its commercially reasonable efforts to have such shares delivered within five
Business Days of such resolution.

(d) Protection of Escrow Fund.

(i) The Depositary shall hold and safeguard the Escrow Fund during the
Escrow Period, shall treat such fund as a trust fund in accordance with the
terms of this Agreement and not as the property of the Parent and shall
hold and dispose of the Escrow Fund only in accordance with the terms
hereof.

(ii) Any shares of Parent Common Stock or other Equity Equivalents
securities issued or distributed by the Parent ("New Shares") in respect of
Parent Common Stock in the Escrow Fund which have not been released from
the Escrow Fund shall be added to the Escrow Fund. New Shares issued in
respect of shares of Parent Common Stock which have been released from the
Escrow Fund shall not be added to the Escrow Fund but shall be distributed
to the record holders thereof. Cash dividends on Parent Common Stock shall
not be added to the Escrow Fund but shall be distributed to the former
shareholders of the Company ratably in proportion to their respective
contributions to the Escrow Fund.

(iii) Each former shareholder of the Company shall have voting rights
with respect to the shares of Parent Common Stock contributed to the Escrow
Fund by such former shareholder of the Company (and on any voting
securities added to the Escrow Fund in respect of such shares of Parent
Common Stock).

(e) Claims Upon Escrow Fund.

(i) Upon receipt by the Depositary at any time on or before the last day
of the Escrow Period of a certificate signed by any officer of the Parent
(an "Officer's Certificate"): (A) stating that the Parent has paid or
properly accrued or reasonably anticipates that it will have to pay or
accrue Losses, directly or indirectly, as a result of any inaccuracy or
breach of any representation, warranty, covenant or agreement of the
Company contained herein or in any instrument delivered pursuant to this
Agreement, and (B) specifying in reasonable detail the bona fide individual
items of Losses included in the amount so stated, the date each such item
was paid or properly accrued, or the bona fide basis for such anticipated
liability, and the nature of the misrepresentation, breach of warranty,
agreement or covenant to which such item is related, the Depositary shall,
subject to the provisions of Section 7.2(f) hereof, deliver to the Parent
out of the Escrow Fund, as promptly as practicable, shares of Parent Common
Stock held in the Escrow Fund in an amount equal to such Losses. No claim
may be made against the Escrow Fund until the aggregate indemnifiable
losses exceed $50,000 and then such claim may be made for such $50,000 of
indemnifiable Losses and any Losses in excess of $50,000.

A-36
<PAGE>

(ii) For the purposes of determining the number of shares of Parent
Common Stock to be delivered to the Parent out of the Escrow Fund pursuant
to Section 7.2(e)(i), the shares of Parent Common Stock shall be valued at
the Closing Price.

(f) Objections to Claims. At the time of delivery of any Officer's
Certificate to the Depositary, a duplicate copy of such certificate shall be
delivered to the Shareholders' Agent and for a period of thirty days after such
delivery, the Depositary shall make no delivery to the Parent of any Escrow
Amounts pursuant to Section 7.2(e) hereof unless the Depositary shall have
received written authorization from the Shareholders' Agent to make such
delivery. After the expiration of such thirty-day period, the Depositary shall
make delivery of shares of Parent Common Stock from the Escrow Fund in
accordance with Section 7.2(e) hereof; provided that no such payment or
delivery may be made if the Shareholders' Agent shall object in a written
statement to the claim made in the Officer's Certificate, and such statement
shall have been delivered to the Depositary prior to the expiration of such
thirty-day period.

(g) Resolution of Conflicts; Arbitration.

(i) In case the Shareholders' Agent shall object in writing to any claim
or claims made in any Officer's Certificate, the Shareholders' Agent and
the Parent shall attempt in good faith to agree upon the rights of the
respective parties with respect to each of such claims. If the
Shareholders' Agent and the Parent should so agree, a memorandum setting
forth such agreement shall be prepared and signed by both parties and shall
be furnished to the Depositary. The Depositary shall be entitled to rely on
any such memorandum and distribute shares of Parent Common Stock from the
Escrow Fund in accordance with the terms thereof.

(ii) If no such agreement can be reached after good faith negotiation,
either the Parent or the Shareholders' Agent may demand arbitration of the
dispute unless the amount of the damage or loss is at issue in a pending
Action or Proceeding involving a Third Party Claim, in which event
arbitration shall not be commenced until such amount is ascertained or both
parties agree to arbitration; and in either event the matter shall be
settled by arbitration conducted by three arbitrators, one selected by the
Parent and one selected by the Shareholders' Agent, and the two arbitrators
selected by the Parent and the Shareholders' Agent shall select a third
arbitrator. The arbitrators shall set a limited time period and establish
procedures designed to reduce the cost and time for discovery of
information relating to any dispute while allowing the parties an
opportunity, adequate as determined in the sole judgment of the
arbitrators, to discover relevant information from the opposing parties
about the subject matter of the dispute. The arbitrators shall rule upon
motions to compel, limit or allow discovery as they shall deem appropriate
given the nature and extent of the disputed claim. The arbitrators shall
also have the authority to impose sanctions, including attorney's fees and
other costs incurred by the parties, to the same extent as a court of law
or equity, should the arbitrators determine that discovery was sought
without substantial justification or that discovery was refused or objected
to by a party without substantial justification. The decision of a majority
of the three arbitrators as to the validity and amount of any claim in such
Officer's Certificate shall be binding and conclusive upon the parties to
this Agreement, and notwithstanding anything in Section 7.2(f) hereof, the
Depositary shall be entitled to act in accordance with such decision and
make or withhold payments out of the Escrow Fund in accordance therewith.
Such decision shall be written and shall be supported by written findings
of fact and conclusions regarding the dispute which shall set forth the
award, judgment, decree or order awarded by the arbitrators.

(iii) Judgment upon any award rendered by the arbitrators may be entered
in any court having competent jurisdiction. Any such arbitration shall be
held in the city and county of Los Angeles, California under the commercial
rules of arbitration then in effect of the American Arbitration
Association. For purposes of this Section 7.2(g), in any arbitration
hereunder in which any claim or the amount thereof stated in the Officer's
Certificate is at issue, the Parent shall be deemed to be the Non-
Prevailing Party in the event that the arbitrators award the Parent less
than the sum of one-half of the bona fide disputed amount of any Losses;
otherwise, the former shareholders of the Company as represented by the
Shareholders' Agent shall be deemed to be the Non-Prevailing Party. The
Non-Prevailing Party to an

A-37
<PAGE>

arbitration shall pay its own expenses, the fees of each arbitrator, the
administrative costs of the arbitration and the expenses, including without
limitation, reasonable attorneys' fees and costs, incurred by the other
party to the arbitration.

(h) Shareholders' Agent of the Shareholders; Power of Attorney.

(i) In the event that the Merger is approved by the shareholders of the
Company, effective upon such vote, and without further act of any
shareholder, the Shareholders' Agent shall be appointed as agent and
attorney-in-fact for each former shareholder of the Company (except such
shareholders, if any, as shall have perfected their appraisal or
dissenters' rights under the Washington Code), for and on behalf of former
shareholders of the Company, to give and receive notices and
communications, to authorize delivery to the Parent of shares of Parent
Common Stock from the Escrow Fund in satisfaction of claims by the Parent,
to object to such deliveries, to agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with
orders of courts and awards of arbitrators with respect to such claims, and
to take all actions necessary or appropriate in the judgment of the
Shareholders' Agent for the accomplishment of the foregoing. Such agency
may be changed by the former shareholders of the Company from time to time
upon not less than thirty days prior written notice to the Parent;
provided, however, that the Shareholders' Agent may not be removed unless
holders of a two-thirds interest in the Escrow Fund agree to such removal
and to the identity of the substituted shareholder agent. Any vacancy in
the position of Shareholders' Agent may be filled by approval of the
holders of a majority in interest of the Escrow Fund. No bond shall be
required of the Shareholders' Agent, and the Shareholders' Agent shall not
receive compensation for his services. Notices or communications to or from
the Shareholders' Agent shall constitute notice to or from each of the
former shareholders of the Company.

(ii) The Shareholders' Agent shall not be liable for any act done or
omitted hereunder as Shareholders' Agent while acting in good faith and in
the exercise of reasonable judgment.

(i) Actions of the Shareholders' Agent. A decision, act, consent or
instruction of the Shareholders' Agent shall constitute a decision of all the
former shareholders of the Company for whom a portion of the Escrow Amount
otherwise issuable to them are deposited in the Escrow Fund and shall be final,
binding and conclusive upon each of such shareholders, and the Depositary and
the Parent may rely upon any such decision, act, consent or instruction of the
Shareholders' Agent as being the decision, act, consent or instruction of every
such shareholder of the Company. The Depositary and the Parent are hereby
relieved from any liability to any person for any acts done by them in
accordance with such decision, act, consent or instruction of the Shareholders'
Agent.

(j) Third-Party Claims. In the event the Parent becomes aware of a third-
party claim (a "Third Party Claim") which the Parent reasonably expects may
result in a demand against the Escrow Fund, the Parent shall notify the
Shareholders' Agent of such claim, and the Shareholders' Agent, as
representative for the shareholders of the Company, shall be entitled, at their
expense, to participate in any defense of such claim. The Parent shall have the
right in its sole discretion to settle any Third Party Claim; provided,
however, that if the Parent settles any Third Party Claim without the
Shareholders' Agent's consent (which consent shall not be unreasonably withheld
or delayed), the Parent may not make a claim against the Escrow Fund with
respect to the amount of Losses incurred by the Parent in such settlement. In
the event that the Shareholders' Agent has consented to any such settlement,
the Shareholders' Agent shall have no power or authority to object under any
provision of this Article 7 to the amount of any claim by the Parent against
the Escrow Fund with respect to the amount of Losses incurred by the Parent in
such settlement.

(k) Depositary's Duties.

(i) The Depositary shall be obligated only for the performance of such
duties as are specifically set forth herein, and as set forth in any
additional written escrow instructions which the Depositary may receive
after the date of this Agreement which are signed by an officer of the
Parent and the Shareholders' Agent, and may rely and shall be protected in
relying or refraining from acting on any instrument reasonably believed to
be genuine and to have been signed or presented by the proper party or
parties.

A-38
<PAGE>

The Depositary shall not be liable for any act done or omitted hereunder as
Depositary while acting in good faith and in the exercise of reasonable
judgment, and any act done or omitted pursuant to the advice of counsel
shall be conclusive evidence of such good faith.

(ii) The Depositary is hereby expressly authorized to comply with and
obey Orders of any court of law or Governmental or Regulatory Authority,
notwithstanding any notices, warnings or other communications from any
party or any other person to the contrary. In case the Depositary obeys or
complies with any such Order, the Depositary shall not be liable to any of
the parties hereto or to any other person by reason of such compliance,
notwithstanding any such Order being subsequently reversed, modified,
annulled, set aside, vacated or found to have been entered without
jurisdiction or proper authority.

(iii) The Depositary shall not be liable in any respect on account of
the identity, authority or rights of the parties executing or delivering or
purporting to execute or deliver this Agreement or any documents or papers
deposited or called for hereunder.

(iv) The Depositary shall not be liable for the expiration of any rights
under any statute of limitations with respect to this Agreement or any
documents deposited with the Depositary.

(v) In performing any duties under the Agreement, the Depositary shall
not be liable to any party for damages, losses, or expenses, except for
gross negligence or willful misconduct on the part of the Depositary. The
Depositary shall not incur any such liability for (A) any act or failure to
act made or omitted in good faith, or (B) any action taken or omitted in
reliance upon any instrument, including any written statement or affidavit
provided for in this Agreement that the Depositary shall in good faith
believe to be genuine, nor will the Depositary be liable or responsible for
forgeries, fraud, impersonations or determining the scope of any
representative authority. In addition, the Depositary may consult with
legal counsel in connection with the Depositary's duties under this
Agreement and shall be fully protected in any act taken, suffered, or
permitted by it in good faith in accordance with the advice of counsel. The
Depositary is not responsible for determining and verifying the authority
of any person acting or purporting to act on behalf of any party to this
Agreement.

(vi) If any controversy arises between the parties to this Agreement, or
with any other party, concerning the subject matter of this Agreement, its
terms or conditions, the Depositary will not be required to determine the
controversy or to take any action regarding it. The Depositary may hold all
documents and shares of Parent Common Stock and may wait for settlement of
any such controversy by final appropriate legal proceedings or other means
as, in the Depositary's discretion, the Depositary may be required, despite
what may be set forth elsewhere in this Agreement. In such event, the
Depositary will not be liable for any damages. Furthermore, the Depositary
may at its option, file an action of interpleader requiring the parties to
answer and litigate any claims and rights among themselves. The Depositary
is authorized to deposit with the clerk of the court all documents and
shares of Parent Common Stock held in escrow, except all costs, expenses,
charges and reasonable attorneys' fees incurred by the Depositary due to
the interpleader action and which the parties jointly and severally agree
to pay. Upon initiating such action, the Depositary shall be fully released
and discharged of and from all obligations and liability imposed by the
terms of this Agreement.

(vii) The parties and their respective successors and assigns agree
jointly and severally to indemnify and hold the Depositary harmless against
any and all Losses incurred by the Depositary in connection with the
performance of the Depositary's duties under this Agreement, including but
not limited to any litigation arising from this Agreement or involving its
subject matter.

(viii) The Depositary may resign at any time upon giving at least thirty
days written notice to the parties; provided, however, that no such
resignation shall become effective until the appointment of a successor
Depositary which shall be accomplished as follows: the parties shall use
their commercially reasonable efforts to mutually agree on a successor
depositary within thirty days after receiving such notice. If the parties
fail to agree upon a successor depositary within such time, the Depositary
shall have

A-39
<PAGE>

the right to appoint a successor depositary authorized to do business in
the State of California; provided, that such successor depositary shall be
consented to by the Parent and the Shareholders' Representative (which
consent shall not be unreasonably withheld or delayed). The successor
depositary shall execute and deliver an instrument accepting such
appointment and it shall, without further acts, be vested with all the
estates, properties, rights, powers, and duties of the predecessor
depositary as if originally named as Depositary. The Depositary shall be
discharged from any further duties and liability under this Agreement.

(l) Fees. All fees of the Depositary for performance of its duties hereunder
shall be paid by the Parent in accordance with the fee schedule previously
delivered to the Parent. In the event that the conditions of this Agreement are
not promptly fulfilled, or if the Depositary renders any service not provided
for in this Agreement, or if the parties request a substantial modification of
its terms, or if any controversy arises, or if the Depositary is made a party
to, or intervenes in, any Action or Proceeding pertaining to this escrow or its
subject matter, the Depositary shall be reasonably compensated for such
extraordinary services and reimbursed for all costs, attorney's fees, and
expenses occasioned by such default, delay, controversy or Action or
Proceeding. The Parent agrees to pay these sums upon demand.

ANNEX B

LETTERHEAD OF THOMAS WEISEL PARTNERS MERCHANT BANKING

October 22, 1999

Board of Directors
Stamps.com Inc.
3420 Ocean Park Boulevard
Santa Monica, CA 90405

Members of the Board:

We understand that iShip.com, Inc., a Washington corporation (the
"Company"), Stamps.com Inc., a Delaware corporation (the "Parent"), and Rocket
Acquisition Corp., a Washington corporation and a wholly owned subsidiary of
the Parent ("Merger Sub") propose to enter into an Agreement and Plan of Merger
(the "Merger Agreement") pursuant to which Merger Sub will be merged with and
into the Company, which will be the surviving entity (the "Merger"). Pursuant
to the Merger, as more fully described in the Merger Agreement, we understand
that (i) each outstanding share of common stock, $0.0005 par value per share,
of the Company ("Company Common Stock"), other than any shares of Company
Common Stock to be cancelled pursuant to Section 1.6(b) of the Merger Agreement
and any dissenting shares, will be converted into the right to receive that
number of shares of common stock, $0.001 par value per share, of the Parent
("Parent Common Stock") equal to the Common Stock Exchange Ratio (as defined in
the Merger Agreement), rounded down to the nearest whole share of Parent Common
Stock, (ii) each outstanding share of Series A preferred stock, $0.0005 par
value per share, of the Company ("Company Series A Preferred Stock"), other
than any shares of Company Series A Preferred Stock to be cancelled pursuant to
Section 1.6(b) of the Merger Agreement and any dissenting shares, will be
converted into the right to receive that number of shares of Parent Common
Stock equal to the Series A Exchange Ratio (as defined in the Merger
Agreement), rounded down to the nearest whole share of Parent Common Stock and
(iii) each outstanding share of Series B preferred stock, $0.0005 par value per
share, of the Company ("Company Series B Preferred Stock" and, together with
the Company Common Stock and the Company Series A Preferred Stock, the "Company
Capital Stock"), other than any shares of Company Series B Preferred Stock to
be cancelled pursuant to Section 1.6(b) of the Merger Agreement and any
dissenting shares, will be converted into the right to receive that number of
shares of Parent Common Stock equal to the Series B Exchange Ratio (as defined
in the Merger Agreement), rounded down to the nearest whole share of Parent
Common Stock; provided that no more than 8,000,000 shares of Parent Common
Stock will be issued in exchange for all outstanding shares of Company Capital
Stock and all vested and unvested options and warrants of the Company. The
number of shares of Parent Common Stock to be issued in exchange for shares of
Company Capital Stock pursuant to the Merger is hereinafter referred to as the
"Consideration". The terms and conditions of the Merger are set forth in more
detail in the Merger Agreement.

You have asked for our opinion as investment bankers as to whether the
Consideration is fair to the Parent from a financial point of view, as of the
date hereof. As you are aware, we were not retained to nor did we advise the
Parent with respect to alternatives to the Merger or the Parent's underlying
decision to proceed with or effect the Merger.

In connection with our opinion, we have, among other things; (i) reviewed
certain publicly available financial and other data with respect to the Parent,
including the consolidated financial statements for recent years and interim
periods to June 30, 1999 and certain other relevant financial and operating
data relating to the Parent made available to us from published sources and
from the internal records of the Parent; (ii) reviewed the consolidated
financial statements of the Company for recent years and interim periods to
September 30,

B-1
<PAGE>

1999 and certain other relevant financial and operating data relating to the
Company made available to us from the internal records of the Company; (iii)
reviewed the financial terms and conditions of a draft dated October 20, 1999
of the Merger Agreement; (iv) reviewed certain publicly available information
concerning the trading of Parent Common Stock; (v) compared the Company and the
Parent from a financial point of view with certain other Internet-based service
companies which we deemed to be relevant; (vi) considered the financial terms,
to the extent publicly available, of selected recent business combinations of
Internet-based service companies which we deemed to be comparable, in whole or
in part, to the Merger; (vii) completed a discounted cash flow analysis of the
Company; (viii) reviewed and discussed with representatives of the management
of the Company and the Parent certain information of a business and financial
nature regarding the Company and the Parent, furnished to us by them, including
financial forecasts and related assumptions of the Company and the Parent; (ix)
made inquiries regarding and discussed the Merger and the Merger Agreement and
other matters related thereto with the Parent's counsel; and (x) performed such
other analyses and examinations as we have deemed appropriate.

In connection with our review, we have not assumed any obligation
independently to verify the foregoing information and have relied on its being
accurate and complete in all material respects. With respect to the financial
forecasts for the Company and the Parent provided to us by their respective
managements, upon their advice and with your consent we have assumed for
purposes of our opinion that the forecasts have been reasonably prepared on
bases reflecting the best available estimates and judgments of their respective
managements at the time of preparation as to the future financial performance
of the Company and the Parent and that they provide a reasonable basis upon
which we can form our opinion. We have also assumed that there have been no
material changes in the Company's or the Parent's assets, financial condition,
results of operations, business or prospects since the respective dates of
their last financial statements made available to us. We have relied on advice
of counsel and independent accountants to the Parent as to all legal and
financial reporting matters with respect to the Parent, the Merger and the
Merger Agreement. We have assumed that the Merger will be consummated in a
manner that complies in all respects with the applicable provisions of the
Securities Act of 1933, as amended (the "Securities Act"), the Securities
Exchange Act of 1934 and all other applicable federal and state statutes, rules
and regulations. In addition, we have not assumed responsibility for making an
independent evaluation, appraisal or physical inspection of any of the assets
or liabilities (contingent or otherwise) of the Company or the Parent, not have
we been furnished with any such appraisals. You have informed us, and we have
assumed, that the Merger will be recorded as a purchase under generally
accepted accounting principles. Finally, our opinion is based on economic,
monetary and market and other conditions as in effect on, and the information
made available to us as of, the date hereof. Accordingly, although subsequent
developments may affect this opinion, we have not assumed any obligation to
update, revise or reaffirm this opinion.

We have further assumed with your consent that the Merger will be
consummated in accordance with the terms described in the draft dated October
20, 1999 of the Merger Agreement, without any further amendments thereto, and
without waiver by the Parent of any of the conditions to its obligations
thereunder.

We will receive a fee for our services in rendering this opinion. In the
ordinary course of our business, we actively trade the equity securities of the
Parent for our own account and for the accounts of customers and, accordingly,
may at any time hold a long or short position in such securities. We have also
acted as an underwriter in connection with offerings of securities of the
Parent and performed various investment banking services for the Parent.

Based upon the foregoing and in reliance thereon, it is our opinion as
investment bankers that the Consideration is fair to the Parent from a
financial point of view, as of the date hereof.

demand procedure.

RCW 23B.13.270

estimate of the fair value of the dissenter's shares and amount of interest
due, and demand payment of the dissenter's estimate, less any payment under RCW
23B.13.250, or reject the corporation's offer under RCW 23B.13.270 and demand
payment of the dissenter's estimate of the fair value of the dissenter's shares
and interest due, if

shares or that the interest due is incorrectly calculated;

C-4
<PAGE>

return the deposited certificates or release the transfer restrictions

under subsection (1) of this section within thirty days after the corporation
made or offered payment for the dissenter's shares.

RCW 23B.13.
Court action.

(1) If a demand for payment under RCW 23B.13.280 remains unsettled, the
corporation shall commence a proceeding within sixty days after receiving the
payment demand and petition the court to determine the fair value of the shares
and accrued interest. If the corporation does not commence the proceeding
within the sixty-day period, it shall pay each dissenter whose demand remains
unsettled the amount demanded.

(2) The corporation shall commence the proceeding in the superior court of
the county where a corporation's principal office, or, if none in this state,
its registered office, is located. If the corporation is a foreign corporation
without a registered office in this state, it shall commence the proceeding in
the county in this state where the registered office of the domestic
corporation merged with or whose shares were acquired by the foreign
corporation was located.

(3) The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled, parties to the proceeding as in an
action against their shares and all parties must be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.

(4) The corporation may join as a party to the proceeding any shareholder
who claims to be a dissenter but who has not, in the opinion of the
corporation, complied with the provisions of this chapter. If the court
determines that such shareholder has not complied with the provisions of this
chapter, the shareholder shall be dismissed as a party.

(5) The jurisdiction of the court in which the proceeding is commenced under
subsection (2) of this section is plenary and exclusive. The court may appoint
one or more persons as appraisers to receive evidence and recommend decision on
the question of fair value. The appraisers have the powers described in the
order appointing them, or in any amendment to it. The dissenters are entitled
to the same discovery rights as parties in other civil proceedings.

(6) Each dissenter made a party to the proceeding is entitled to judgment
(a) for the amount, if any, by which the court finds the fair value of the
dissenter's shares, plus interest, exceeds the amount paid by the corporation,
or (b) for the fair value, plus accrued interest, of the dissenter's after-
acquired shares for which the corporation elected to withhold payment under RCW
23B.13.270.

RCW 23B.13.310
Court costs and counsel fees.

(1) The court in a proceeding commenced under RCW 23B.13.300 shall determine
all costs of the proceeding, including the reasonable compensation and expenses
of appraisers appointed by the court. The court shall assess the costs against
the corporation, except that the court may assess the costs against all or some
of the dissenters, in amounts the court finds equitable, to the extent the
court finds the dissenters acted arbitrarily, vexatiously, or not in good faith
in demanding payment under RCW 23 B.13.280.

(2) The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable:

C-5
<PAGE>

(a) Against the corporation and in favor of any or all dissenters if the
court finds the corporation did not substantially comply with the
requirements of RCW 23B.13.200 through 23B. 13.280; or

(b) Against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses
are assessed acted arbitrarily, vexatiously, or not in good faith with
respect to the rights provided by chapter 23B.13 RCW.

(3) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the
fees for those services should not be assessed against the corporation, the
court may award to these counsel reasonable fees to be paid out of the amounts
awarded the dissenters who were benefited.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

The Amended and Restated Certificate of Incorporation (the "Certificate") of
Stamps.com Inc., a Delaware corporation (the "Company"), provides that, except
to the extent prohibited by the General Corporation Law of the State of
Delaware (the "DGCL"), the Company's directors shall not be personally liable
to the Company or its stockholders for monetary damages for any breach of
fiduciary duty as directors of the Company. Under the DGCL, the directors have
a fiduciary duty to the Company which is not eliminated by this provision of
the Certificate and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of nonmonetary relief will remain available. In
addition, each director will continue to be subject to liability under the DGCL
for breach of the director's duty of loyalty to the Company, for acts or
omissions which are found by a court of competent jurisdiction to be not in
good faith or involving intentional misconduct, for knowing violations of law,
for actions leading to improper personal benefit to the director, and for
payment of dividends or approval of stock repurchases or redemptions that are
prohibited by DGCL. This provision also does not affect the directors'
responsibilities under any other laws, such as the federal securities laws or
state or federal environmental laws. The Company has obtained liability
insurance for its officers and directors.

Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this
provision shall not eliminate or limit the liability of a director: (i) for any
breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) arising under
Section 174 of the DGCL, or (iv) for any transaction from which the director
derived an improper personal benefit. The DGCL provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
Certificate eliminates the personal liability of directors to the fullest
extent permitted by Section 102(b)(7) of the DGCL and provides that the Company
shall fully indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding
(whether civil, criminal, administrative or investigative) by reason of the
fact that such person is or was a director or officer of the Company, or is or
was serving at the request of the Company as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorney's fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.

The Company, with the approval of its board of directors, has obtained
directors' and officers' liability insurance. In addition, the Company has
entered into indemnification agreements with each of its directors and
executive officers, a form of which is Exhibit 10.10 hereto.

There is no pending litigation or proceeding involving any director,
officer, employee or agent of the Company in which indemnification will be
required or permitted. Moreover, the Company is not aware of any threatened
litigation or proceeding that might result in a claim for such indemnification.
The Company believes that the foregoing indemnification provisions and
agreements are necessary to attract and retain qualified persons as directors
and executive officers.

(2) that, for purpose of determining any liability under the Securities
Act, each such post effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

(3) to remove from registration by means of a post-effective amendment
any of the securities which remain unsold at the termination of the
offering.

(d) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has
been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit, or proceeding) is asserted by such director,
officer or controlling person in connection with the securities being
registered, the Company will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

Re: Stamps.com Inc. Registration Statement on Form S-4
for 8,000,000 Shares of Common Stock
------------------------------------

Ladies and Gentlemen:

We have acted as special counsel to Stamps.com Inc., a Delaware
corporation (the "Company"), in connection with the proposed issuance and sale
by the Company of up to 8,000,000 shares of the Company's common stock, par
value $0.001 per share (the "Shares"), pursuant to the Company's Registration
Statement on Form S-4 (File No. 333-91377) (the "Registration Statement") filed
with the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Securities Act").

This opinion is being furnished in accordance with the requirements of
Item 16(a) of Item 21(a) of Form S-4 and Item 601(b)(5)(i) of Regulation S-K.

We have reviewed (i) the Company's charter documents, (ii) the
corporate proceedings taken by the Company in connection with the issuance and
sale of the Shares, (iii) the Agreement and Plan of Merger, dated as of October
22, 1999 (the "Agreement") by and among the Company, Rocket Acquisition Corp., a
Washington corporation and a wholly owned subsidiary of the Company ("Merger
Sub"), and iShip.com, Inc., a Washington corporation ("iShip.com"), and (iv) the
Registration Statement. Based on such review, we are of the opinion that the
Shares have been duly authorized, and if, as and when issued in accordance with
the Registration Statement and the related joint proxy statement and consent
solicitation/prospectus (as amended and supplemented through the date of
issuance) will be legally issued, fully paid and nonassessable.

We consent to the filing of this opinion letter as Exhibit 5.1 to the
Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the joint proxy statement and consent solicitation/prospectus
which is part of the Registration Statement. In giving this consent, we do not
thereby admit that we are within the category of persons whose consent is
required under Section 7 of the Securities Act, the rules and regulations of the
Commission promulgated thereunder, or Item 509 of Regulation S-K.

January 3, 2000

Stamps.com Inc.
3420 Ocean Boulevard, Suite 1040
Santa Monica, CA 90405

Ladies and Gentlemen:

This opinion is being delivered to you in connection with (i) the
Agreement and Plan of Merger, dated as of October 22, 1999 (the "Agreement"),
between Stamps.com Inc., a Delaware corporation ("Stamps.com"), Rocket
Acquisition Corp., a Washington corporation and a wholly owned subsidiary of
Stamps.com ("Merger Sub"), and iShip.com, Inc., a Washington corporation
("iShip.com"), and (ii) the preparation and filing with the Securities and
Exchange Commission of a Form S-4 Registration Statement relating to the Merger
(the "Registration Statement"). Pursuant to the Agreement, Merger Sub will merge
with and into iShip.com (the "Merger"), and iShip.com will become a wholly owned
subsidiary of Stamps.com.

Except as otherwise provided, capitalized terms referred to herein
have the respective meanings ascribed to them in the Agreement. All section
references, unless otherwise indicated, are to the Internal Revenue Code of
1986, as amended (the "Code").

We have acted as legal counsel to Stamps.com in connection with the
Merger. As such, and for the purpose of rendering this opinion, we have
examined and are relying upon (without any independent investigation or review
thereof) the truth and accuracy, at all relevant times, of the statements,
covenants, representations and warranties contained in the following documents
(including all schedules and exhibits thereto):

1. The Agreement;

2. The Registration Statement;

3. Such other instruments and documents related to Stamps.com,
iShip.com and Merger Sub and to the consummation of the Merger and the other
transactions contemplated by the Agreement as we have deemed necessary or
appropriate.

<PAGE>

Stamps.com Inc. January 3, 2000

In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:

A. Original documents submitted to us (including signatures) are
authentic, documents submitted to us as copies conform to the original
documents, and there has been (or will be by the Effective Time) due execution
and delivery of all documents where due execution and delivery are prerequisites
to the effectiveness thereof; and

B. The Merger will be consummated in accordance with the Agreement
without any waiver or breach of any material provision thereof, and the Merger
will be effective under applicable state law.

Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein and in
the Registration Statement under the heading "The Merger Agreement - Federal
Income Tax Considerations,", we are of the opinion that the statements regarding
United States federal income tax consequences set forth in the Registration
Statement under the heading "The Merger Agreement - Federal Income Tax
Considerations," insofar as they constitute statements of law or legal
conclusions, are correct in all material respects and represent a description of
the material federal income tax consequences of the Merger. We express no
opinion as to any federal, state or local, foreign or other tax consequences,
other than as set forth in the Registration Statement under the heading "The
Merger Agreement - Federal Income Tax Considerations."

In addition to the assumptions and representations described above,
this opinion is subject to the exceptions, limitations and qualifications set
forth below.

(1) This opinion represents and is based upon our best judgment
regarding the application of federal income tax laws arising under the Code,
existing judicial decisions, administrative regulations and published rulings
and procedures. Our opinion is not binding upon the Internal Revenue Service or
the courts, and there is no assurance that the Internal Revenue Service will not
successfully assert a contrary position. Furthermore, no assurance can be given
that future legislative, judicial or administrative changes, on either a
prospective or retroactive basis, will not adversely affect the accuracy of the
conclusions stated herein. Nevertheless, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
federal income tax laws.

(2) No opinion is expressed as to any transaction other than the
Merger (whether or not undertaken in connection with the Merger) or as to any
transaction whatsoever, including the Merger, if all the transactions described
in the Agreement are not consummated in accordance with the terms of such
Agreement and without waiver or breach of any material provision thereof or if
all of the statements, representations, warranties and assumptions upon which we
relied are not true and accurate at all relevant times. In the event any one of
the
<PAGE>

Stamps.com Inc. January 3, 2000
Page 3

statements, representations, warranties or assumptions upon which we have relied
to issue this opinion is incorrect, our opinion might be adversely affected and
may not be relied upon.

This opinion is rendered to you solely in connection with the filing
of the Registration Statement. We hereby consent to the filing of this opinion
as an exhibit to the Registration Statement. We also consent to the references
to our firm name wherever appearing in the Registration Statement with respect
to the discussion of the federal income tax consequences of the Merger,
including any amendments to the Registration Statement. This opinion may not be
relied upon for any other purpose, and may not be made available to any other
person, without our prior written consent.

Very truly yours,
