                                    SUMMARY

    This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus, including "Risk Factors" and the
financial statements, carefully before making an investment decision.

                                  The Company

    We provide comprehensive electronic bill publishing services via the
telephone and Internet to large businesses, which generate recurring bills, and
financial institutions. Our bill publishing services are comprised of both the
presentment and payment of bills. We also provide electronic lockbox and credit
card balance transfer services to large businesses and financial institutions.

    Our telephone bill publishing service enables consumers to access billing
information and to pay bills in as few as five keystrokes and to set up
automatic payment of recurring bills. Our Internet bill publishing service
eliminates the need for billers to generate and mail paper bills. Both our
telephone and Internet services eliminate the need for consumers to write and
mail paper checks. Our Internet bill publishing service allows billers to
publish bills directly through their own web sites or indirectly through web
sites of financial institutions and Internet portals. An Internet portal is a
high-traffic web site that allows people to search, navigate, retrieve
information and access services via the Internet. Using our service, consumers
have numerous options of how, where and when to access, analyze and pay their
bills. Our electronic lockbox service, which is a stand-alone service as well
as a key component of both our telephone and Internet bill publishing services,
is a clearinghouse for electronic consumer-initiated payments. Our credit card
balance transfer service allows electronic transfers of balances from one
credit card institution to another. As of May 31, 1999, of our more than 250
corporate customers, 45 were utilizing our electronic bill publishing services.
Of these customers, 14 are currently utilizing our Internet bill publishing
service. We have incurred losses in each of the last five years and expect to
continue to incur losses from operations in the forseeable future.

    According to Jupiter Communications, in 1998 approximately 15 billion
consumer paper bills were received by approximately 100 million U.S.
households. Creating and presenting a paper bill is a multiple-step process
that is costly and labor intensive for a biller. According to Gartner Group,
the average cost to a biller of creating and delivering a paper bill is $1.00.
The bill payment process is also time consuming for the consumer.

    Billers have traditionally mailed their consumers paper bills and, in turn,
consumers have paid their bills by mailing checks. With technology
advancements, billers have begun to use non-paper based billing alternatives
designed to reduce their billing costs and to provide their consumers with
increased convenience. The Internet has provided the opportunity to
dramatically simplify the bill presentment and payment process, to greatly
reduce the cost to billers and to improve the convenience for consumers. As the
Internet gains increased acceptance as a medium for financial services, we
believe that more billers will begin to utilize Internet bill presentment and
payment services.

    Most billers lack the expertise to cost-effectively implement and maintain
the hardware and software necessary to present bills and process consumer
payments through the Internet. Billers choosing to use the Internet to
facilitate the billing process must decide whether to develop Internet bill
presentment and payment capabilities internally or to outsource the process.
Our electronic bill publishing services dramatically simplify the bill
presentment and payment process, providing the following key benefits to our
customers:

  .  comprehensive, cost-effective outsourcing of the entire bill presentment
     and payment process;

  .  broad distribution that provides consumers with numerous options of how,
     where and when to access and pay their bills;
  .  fully customized Internet-based consumer billing interface that allows
     billers, financial institutions and Internet portals to preserve the
     existing look and feel of their web sites;

                                       4
<PAGE>

  .  reliable system architecture that is expandable at relatively low cost;
  .  enhanced network and data security; and
  .  ease of integration with billers' financial accounting systems.

    Although the Internet bill presentment and payment market is in the early
stages of development, we have leveraged our existing services to position
ourselves as a market leader in this emerging industry.

    On January 25, 1984, we were incorporated in the State of Delaware under
the name Princeton TeleCom Corporation. On March 24, 1999, we changed our name
to Princeton eCom Corporation. Our principal office is located at 165 Wall
Street, Princeton, New Jersey 08540 and our telephone number is 1-800-PayBill.
Our web site address is www.princetonecom.com. The information on our web site
is not a part of this prospectus.

    Prior to completion of this offering, we will effect a 3- for-1 stock split
in the form of a stock dividend. Unless otherwise noted, the information in
this prospectus assumes that the stock split has been effected and that the
underwriters will not exercise their over-allotment option.

continue to incur losses from operations for the foreseeable future. We cannot
assure you that we will ever become profitable. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

    We intend to expend significant resources on our sales, marketing and new
customer implementation operations. As a result, we will need to achieve
significant revenue increases to achieve and maintain profitability. We cannot
assure you that we will be able to achieve the necessary revenue growth. Our
number of customers or the number of services which our customers buy from us
may grow more slowly than we anticipate or may decrease in the future.

Our business model is unproven and is evolving

    The electronic bill presentment and payment industry, which includes all
non-paper based mediums, is an evolving industry. During the first quarter of
1999, 30% of our service fee revenues were generated from our 14 customers who
use both our telephone and Internet bill publishing services. Although we have
expended and will continue to expend considerable resources in developing our
Internet bill publishing service, we need to achieve critical mass in terms of
number of billers and consumers that use the service in order for it to
succeed. Even with the successful growth of Internet usage, our business model
will not succeed if consumers are not receptive to using the Internet to pay
their bills. If a significant number of billers fail to adopt our Internet bill
publishing service or adopt this service more slowly than we anticipate, or if
we fail to retain new billers or further expand this service to penetrate our
existing non-Internet customer base, our business would be materially and
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations," and "Business -- The Princeton eCom
Strategy."

Our operating results may fluctuate significantly from quarter to quarter,
which may negatively impact our stock price

    Our quarterly operating results may fluctuate significantly in the future
as a result of a variety of factors, many of which are outside of our control.
These factors include:

<TABLE>
<S>  <C>                                  . the loss of key employees and the
                                            time and expense needed to
 . the rate at which we increase             recruit, hire and train new
  our customer base and their use           personnel, particularly service
  of our various services;                  development personnel;


 . the amount and timing of costs          . our ability to upgrade, enhance
  related to our sales and                  and maintain our systems and
  marketing efforts and other               infrastructure and the timing and
  initiatives;                              cost of this;


 . sales and implementation cycles         . interest rate fluctuations; and
  of our customers;


                                          . economic conditions which may
 . the loss of a number of existing          affect the budgets of billers,
  customers;                                financial institutions and
                                            consumers for technological
                                            expenditures.
</TABLE>

                                       7
<PAGE>

    Because of these factors, we believe that comparisons of our quarterly
operating results are not necessarily meaningful. In addition, it is possible
that in some future quarters our operating results will be below the
expectations of research analysts and investors, and in that case, the price of
our common stock is likely to decline.

If we fail to respond to rapid technological change, our business will suffer

    The electronic bill presentment and payment industry is characterized by
rapid technological change. As a result, the emergence of new industry
standards and practices could render our existing technologies and systems, and
thus our services, obsolete. The development of our technologies and necessary
service enhancements entails significant technical and business risks and
requires substantial lead-time and expenditures. We may not be able to keep
pace with the latest technological developments, successfully identify and meet
our customer demands, use new technologies effectively or adapt our services to
customer requirements or emerging industry standards. If we cannot adapt or
respond in a cost-effective and timely manner to technological changes, our
business, operating results and financial condition will be materially and
adversely affected.

If we do not develop relationships with significant Internet aggregators of
consumer bills, our business will suffer

    We believe that in order to be successful in the Internet bill presentment
and payment industry, we must have relationships with a number of aggregators
that will enable our customers, through our Internet bill publishing service,
to reach a significant portion of their consumer audience. An aggregator is a
company that consolidates bills from different billers and bill publishers and
then distributes the bills to web sites of financial institutions and portals
where consumers can go to pay their bills. We cannot assure you that we will be
able to achieve or maintain this minimum number of relationships and our
failure to do so would have a material and adverse effect on our business,
operating results and financial condition.

Increased competition in the electronic bill presentment and payment markets
could materially and adversely affect our business

    Increased competition in the electronic bill presentment and payment market
could have a material and adverse effect on our business, operating results and
financial condition. We believe that the principal competitive factors are:

  .ability to identify and respond to customer needs;

  .technical expertise;

  .quality of the service;

  .price of the service;

  .breadth of distribution; and

  . possible preexisting relationships between companies that process paper
    bills or lockbox service providers and our potential customers.

    In addition to the foregoing, our Internet bill presentment services also
face competitive pressures from various third-party software vendors, which
provide some of the software necessary for the development of an integrated,
in-house Internet bill publishing service. In addition, these companies could
potentially leverage their existing capabilities and relationships to enter the
outsourced Internet bill presentment and payment market.

    Many of our actual and potential competitors have significantly greater
financial, marketing, technical, sales and customer support and other
resources, larger customer bases and longer relationships with customers

                                       8
<PAGE>

than we do. In addition, some of these potential competitors may be able to
devote greater resources to the development, promotion and sale of their
services, adopt more aggressive pricing strategies and devote substantially
more resources to the development of technology and systems development than we
are able.

    Increased competition may result in reduced operating margins, loss of
market share and diminished value of our services, as well as different
pricing, service and marketing strategies. We may not be able to compete
successfully against current and future competitors, and competitive pressures
we face could have a material and adverse effect on our business, operating
results and financial condition.

If we fail to successfully expand our sales and marketing activities, our
business will be materially and adversely affected

    We intend to expand our sales and marketing activities by hiring additional
sales and marketing personnel. Our ability to expand our sales and marketing
activities involves a number of risks including:

  . our ability to successfully integrate future sales and marketing
    personnel; and

  . our ability to hire, retain, integrate and motivate sales and marketing
    personnel in a very competitive environment.

    We cannot assure you that we will be successful in expanding our sales and
marketing personnel, and our failure to do so would have a material and adverse
effect on our sales and marketing efforts and on our business, operating
results and financial condition.

A number of members of our management team have little experience working
together, and we depend on a few key employees

    Our future success will depend upon the continued service of key management
and technical personnel. Ronald W. Averett, our President and Chief Operating
Officer, joined us in March 1999 and Christopher S. Sugden, our Senior Vice
President and Chief Financial Officer, joined us in February 1999. Three other
members of our senior management team have joined us since April 1999. Given
their limited experience with our business and other members of management, it
is possible that these officers may not integrate well into our business. Their
failure to integrate well would have a material and adverse effect on our
business, operating results and financial condition.

    We currently do not maintain key man life insurance policies on any of our
employees. We do not have employment agreements with any of our employees other
than Messrs. Averett and Sugden. The loss of the services of any of our key
employees or our inability to hire and retain additional key employees would
have a material and adverse effect on our business, operating results and
financial condition. See "Management --  Employment Agreements."

If we fail to effectively manage our internal growth, our business will be
materially and adversely affected

    We recently began to significantly expand our operations and intend to
continue this expansion. We increased our employee base from 56 at December 31,
1997 to 95 at May 31, 1999. This expansion has placed, and is expected to
continue to place, a significant strain on our managerial, operational and
financial resources. We must hire additional managerial, and sales and
marketing employees. In addition, we cannot assure you that we can successfully
integrate any new management personnel into our existing management team. We
cannot assure you that current and planned personnel, systems, procedures and
controls will be adequate to support our future operations. If we are unable to
manage our growth effectively, the quality of our services, our ability to
train and retain key personnel, and our business, operating results and
financial condition will be materially and adversely affected.

                                       9
<PAGE>

We will be dependent on our relationships with financial institutions to help
market our services and our business would be materially and adversely affected
if we were to lose some of these relationships

    We will be dependent on our relationships with financial institutions to
help market our services to more billers. Our ability to increase revenues
depends partially upon our ability to market our services through new and
existing relationships. If we lose some of these relationships or fail to
develop new ones, our business will not meet growth expectations and our
business, operating results and financial condition will be materially and
adversely affected.

If our system security is breached, our business will be materially and
adversely affected

    A fundamental requirement for Internet bill presentment and payment
services is the secure transmission of confidential information over public
computer networks. Third parties may attempt to breach our system security or
that of our customers. If they are successful, we may be liable to our billers
or their consumers for any breach in our system security and any breach could
harm our reputation.

    Our computer servers are vulnerable to computer viruses, physical or
electronic break-ins and similar disruptions, which could lead to interruptions
or delays in processing transactions, or the manipulation or loss of data. We
may be required to expend significant capital and other resources to license
encryption technology and additional technologies to protect against system
security breaches or to alleviate problems caused by any breach. Our failure to
prevent system security breaches would have a material and adverse effect on
our business, operating results and financial condition.

Our operations are dependent upon systems which are located at a single site
and an interruption of our systems could materially and adversely affect our
business

    Our success depends largely upon the efficient and uninterrupted operation
of our operating systems. All of our operating systems are located at a single
facility leased by us in Princeton, New Jersey. Our systems are vulnerable to
damage or interruption from fire, power loss, telecommunications failure,
break-ins and similar events. We cannot assure you that we will not experience
system failures in the future. The occurrence of a system failure or similar
event could have a material and adverse effect on our business, operating
results and financial condition.

A constraint in capacity to process transactions would materially and adversely
affect our business

    Capacity constraints in processing transactions, due to a sharp increase in
traffic, may cause unanticipated system disruptions, impair quality and lower
the level of our service. If this were to happen, our business, operating
results and financial condition will be materially and adversely affected.

We do not have any long-term contracts with our billers or aggregators

    All of our contracts with our billers and aggregators are short-term and
can be terminated without cause, generally upon 30 to 90 days' notice. Our
future success depends on our ability to retain our current billers and
aggregators and attract new billers and aggregators. The loss of several of our
larger existing billers or aggregators, or our inability to attract new billers
or a major aggregator, would have a material and adverse effect on our
business, operating results and financial condition.

If our services do not function as designed, we may incur significant liability

    Our electronic bill publishing services are designed to provide payment
management functions and to limit the billers' risk of fraud or loss in
effecting transactions with their consumers. As our electronic services become
more critical to our billers, there is a potential for significant liability
claims for the processing of fraudulent or erroneous transactions. If a
liability claim were brought against us, even if not

                                       10
<PAGE>

successful, its defense would likely be time consuming and costly and could
injure our reputation. A successful liability claim may have a material and
adverse effect on our business, operating results and financial condition.

Our failure to successfully integrate any future acquisitions would strain our
managerial, operational and financial resources

    As part of our business strategy, we intend to pursue strategic
acquisitions that would provide additional technologies, billers, services or
experienced personnel. Acquisitions present a number of potential risks that
would have a material and adverse effect on our business, operating results and
financial condition, including:

  . difficulties in assimilating the acquired company's personnel,
    operations and technologies;

  . the potential loss of key employees of the acquired company;

  . the distraction of our management's attention from other business
    concerns; and

  . potentially dilutive issuances of our common stock or the incurrence of
    substantial amounts of debt.

Year 2000 problems would adversely affect our business

    In order to accurately provide our services, we must rely on technology
supported by billers, financial institutions, aggregators, presenters and
consumers. Furthermore, our services rely on the transmission of information
over the phone lines and data over the Internet, third party data and voice
communication lines, and data transmission through wire transfer systems,
including the Federal Funds system. Failure by us, our billers, aggregators,
presenters or suppliers to adequately address Year 2000 issues in a timely
manner could impede our ability to provide our services and have a direct
impact on our ability to generate revenue. This, in turn, could have a material
and adverse impact on our business, financial condition and results of
operations.

If we are unable to protect our intellectual property rights, our business will
be materially and adversely affected

    We protect our intellectual property rights through a combination of
trademark, copyright and trade secrets laws. We cannot assure you that the
steps we have taken to protect our intellectual property rights, however, will
be adequate to deter misappropriation of those rights. In addition, we cannot
be certain that our services do not infringe valid patents, copyrights and
intellectual property rights held by third parties. See "Business --
 Proprietary Rights."

Our revenue could be negatively impacted by decreases in interest earned on
overnight investments

    For the three months ended March 31, 1999, approximately 36% of our revenue
was generated from interest paid on amounts deposited overnight with financial
institutions pending payment. The interest earned is based on the prevailing
short-term interest rates. Accordingly, fluctuations in the short-term interest
rates will affect our revenues. Likewise, a decrease in revenue generated by
overnight investment may not be met by a corresponding decrease in any
borrowing costs which we may incur in the future. Thus, either a fall in the
prevailing short-term interest rates or an increase in future borrowing costs
could materially and adversely affect our business, operating results and
financial condition.

                         Risks Related to Our Industry

Government regulation and the legal uncertainties relating to the services we
provide would cause our business to suffer

    Our management believes that we are not required to be licensed by the
Office of the Comptroller of the Currency, the Federal Reserve Board, or other
federal or state agencies that regulate or monitor banks or other types of
providers of electronic commerce services. We cannot assure you that a federal
or state agency will not attempt, either now or in the future, to require that
providers of services like ours be licensed. This would impede our ability to
do business in the areas within the regulator's jurisdiction. In conducting
several aspects of our business, we are subject to various laws and regulations
relating to commercial transactions generally, such as the Uniform Commercial
Code. We are also subject to the electronic funds transfer rules embodied in
Regulation E promulgated by the Federal Reserve Board. Given the expansion of
the electronic commerce market, it is possible that the Federal Reserve might
revise Regulation E or adopt new rules for electronic funds transfer affecting
users other than consumers. It is possible that Congress or individual states
could enact laws regulating the electronic commerce market. If enacted, these
laws, rules and regulations could be imposed on our business and industry and
would have a material and adverse effect on our business, operating results and
financial condition. In addition, any new laws or regulations relating to the
Internet would have a material and adverse effect on our business, operating
results and financial condition. See "Business -- Government Regulations."

We depend on the continued growth in the use of the Internet and the
development of the Internet infrastructure

    The growth of our business would be materially and adversely affected if
Internet usage does not continue to grow rapidly. Internet usage may be
inhibited for a number of reasons, including:

  . concerns about the security of confidential information;

  . lack of reliability and ease of access;

  . lack of cost-effective, high-speed service;

  . inconsistent quality of service;

  . inadequate network infrastructure; or

  . adoption of onerous governmental regulations.

    In addition, the Internet infrastructure may not be able to support the
demands placed on it by increased Internet usage and its performance and
reliability may decline. Internet web sites have experienced interruptions in
their service as a result of outages and other delays occurring throughout the
Internet network infrastructure. If these outages or delays frequently occur in
the future, Internet usage, as well as the use of our Internet bill publishing
service, could grow more slowly than projected or decline.

We may encounter Internet security concerns that would hinder Internet commerce

    The secure transmission of confidential information over the Internet is an
important component of electronic commerce and communications over the
Internet. Because a number of our services involve the transfer of confidential
information, our business, operating results and financial condition could be
materially and adversely affected if Internet users significantly reduce their
use of the Internet because of system security concerns. We may also be
required to expend significant time and resources to protect our services
against the threat of security breaches or to alleviate problems caused by such
breaches.

                        Risks Relating to this Offering

We are controlled by Donald C. Licciardello, our Chairman and Chief Executive
Officer, whose interests may differ from those of other stockholders

    After this offering, Donald C. Licciardello, our Chairman and Chief
Executive Officer, will control, either directly or indirectly through the
Donald Licciardello Family Limited Partnership, approximately 48.8%, or 47.3%
if the underwriters' overallotment option is exercised in full, of our
outstanding common stock. As a result, he will have the ability to control our
management and affairs, and to control substantially all matters submitted to
our stockholders for approval, including the election and removal of directors
and any merger, consolidation or sale of all or substantially all of our
assets. This concentration of control may have the effect of deterring a change
in control of Princeton eCom, including impeding a merger, consolidation,
takeover or other business transaction involving us or discouraging a potential
acquirer from making a tender offer or otherwise attempting to obtain control
of Princeton eCom. Any of the foregoing results could, in turn, materially and
adversely affect the market price for our common stock. See "Principal
Stockholders."

Billing Concepts Corp. has the ability to appoint two members of our Board of
Directors

    Pursuant to the terms of a voting agreement, as amended, entered into among
Billing Concepts, Donald C. Licciardello and the Donald Licciardello Family
Limited Partnership, of which Mr. Licciardello is the general partner, in
connection with Billing Concepts' purchase of shares of Princeton eCom in
September 1998, Billing Concepts, Mr. Licciardello and the Donald Licciardello
Family Limited Partnership have agreed to vote all of their respective shares
of common stock to elect to our board two individuals designated by Billing
Concepts and three individuals designated by Mr. Licciardello. As a result,
Billing Concepts, the holder of 18.3% of our common stock after this offering
(17.8% if the underwriters' overallotment option is exercised in full), can
designate 40% of the members of our board. Through this disproportionate voting
power, Billing Concepts may be able to influence the outcome of a decision
which may not be in the best interests of all stockholders. See "Certain
Transactions."

Certain provisions of Delaware law, our certificate of incorporation and our
by-laws may make a takeover of our company more difficult which could
materially and adversely affect the market price for our common stock

    We are subject to the anti-takeover provisions of Section 203 of the
Delaware General Corporation Law. Section 203 could delay or prevent a third
party or a significant stockholder from acquiring control of us. In addition,
provisions of our certificate of incorporation and by-laws may have the effect
of discouraging, delaying or preventing a merger, tender offer or proxy contest
involving Princeton eCom, even if such transaction would be beneficial to our
stockholders. See "Description of Capital Stock."

Future sales of our common stock in the public market may depress our stock
price

    The market price of our common stock could decline as a result of sales by
our existing stockholders of a large number of shares of common stock in the
market after this offering, or the perception that these sales may occur. These
sales also might make it more difficult for us to sell equity securities in the
future and at a price that we deem appropriate. See "Shares Eligible for Future
Sale."

You will experience an immediate and substantial dilution in the book value of
your investment

    Investors purchasing shares in this offering will incur immediate and
substantial dilution in net tangible book value per share. To the extent
outstanding options to purchase common stock are exercised, there will be
further dilution. See "Dilution."

                                       13
<PAGE>

Trading in our common stock could be subject to extreme price and volume
fluctuations and you could have difficulty trading your shares of common stock

    We cannot predict the extent to which investor interest in Princeton eCom
will lead to the development of an active trading market or that the market
price of our common stock will not decline below the initial public offering
price. The stock market has experienced significant price and volume
fluctuations and the market prices of securities of technology companies,
particularly Internet-related companies, have been extremely volatile.
Investors may not be able to resell their shares at or above the initial public
offering price.

<PAGE>

                                USE OF PROCEEDS

    The net proceeds we receive from this offering are estimated to be
approximately $26.7 million, $30.9 million if the underwriters' over-allotment
option is exercised in full, assuming an initial public offering price of
$10.00 per share, after deducting the underwriting discounts and commissions
and estimated offering expenses payable by us. The principal uses of the net
proceeds will be to invest in the further growth and expansion of our business
and for working capital and other general corporate purposes. In addition, we
may use a portion of the net proceeds from this offering to acquire or invest
in complementary businesses. However, we do not currently have commitments or
agreements to make such investment.

    As of the date of this prospectus, we have not identified with certainty
the specific uses for the net proceeds from this offering. Consequently, our
management will have discretion over their use and investment. Pending their
use, the net proceeds will be invested in short-term, investment grade,
interest-bearing instruments, certificates of deposit or direct or guaranteed
obligations of the United States government.

                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our common stock and
do not intend to pay any cash dividends in the foreseeable future. We currently
anticipate that all future earnings, if any, will be retained to finance the
further expansion and continued growth of our business. Any future
determination regarding the payment of cash dividends will be within the sole
discretion of our board of directors and will depend upon, among other things,
our earnings, operating results, financial condition and current and
anticipated cash needs.

                                    DILUTION

    Our net tangible book value as of March 31, 1999 was $188,611, or $0.02 per
share of common stock. Net tangible book value per share represents the amount
of our total tangible assets less our total liabilities, divided by the number
of shares of our common stock outstanding. After giving effect to our sale of
3,000,000 shares of common stock in this offering at an estimated offering
price of $10.00 per share and the application of the estimated net proceeds of
this offering, our net tangible book value as of March 31, 1999 would have been
approximately $26,888,611, or $1.88 per share of common stock. This represents
an immediate increase in the net tangible book value of $1.86 per share to
existing stockholders and an immediate dilution in the net tangible book value
of $8.12 per share to new investors buying common stock in this offering. The
following table illustrates this per share dilution:

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

    The following discussion should be read in conjunction with our financial
statements and the related notes which are included elsewhere in this
prospectus. The following discussion contains forward-looking statements that
involve risks and uncertainties. Our actual results could differ significantly
from those discussed in these forward-looking statements as a result of various
factors, including, but not limited to, those set forth under "Risk Factors"
and elsewhere in this prospectus.

Overview

    We provide comprehensive electronic bill publishing services via the
telephone and Internet to large businesses, which generate recurring bills, and
financial institutions. Our bill publishing services are comprised of both the
presentment and payment of bills. We also provide electronic lockbox and credit
card balance transfer services to large businesses and financial institutions.
Our telephone bill publishing service enables consumers to access billing
information and to pay bills in as few as five keystrokes and set up automatic
payment of recurring bills. Our Internet bill publishing service allows billers
to publish bills directly through their own web sites or indirectly through web
sites of financial institutions and Internet portals.

    Our revenues are primarily derived from two sources.

  . Service Fees. We derive revenue from contractual relationships with
    billers and financial institutions. Service fee revenues, which
    represent transaction fees charged by us for our services, are
    recognized as the services are performed.

  . Interest. We also derive revenue through the overnight investment of
    funds received pending payment. These funds are invested overnight in
    investment grade and government securities while we reconcile consumer
    and financial institution payments with our customers' accounting
    databases. Interest revenue is recorded as it is earned.

    We intend to significantly increase our sales and marketing and new
customer implementation expenditures during 1999. We believe these expenditures
will enable us to grow our biller base and continue to expand our relationships
with aggregators. We also believe that we can increase our share of the
Internet bill presentment and payment market through the establishment or
expansion of strategic relationships with providers of paper-based billing
services and financial institutions that have existing relationships with our
targeted biller customer base.

    We incur development costs in connection with developing our services. To
date, we have not capitalized any development costs. We expect to significantly
increase our development costs in the future as we enhance our current services
and develop new service offerings. This increase will primarily relate to the
hiring of additional employees performing technical support and computer
programming functions.

    During 1998, we recorded an aggregate deferred compensation expense of
approximately $1.9 million in connection with the grant of stock options to our
employees and directors at exercise prices below the fair market value of our
common stock. We are amortizing this deferred compensation expense over the
vesting periods of the options, which range from immediate vesting to periods
of up to four years. Of the $1.9 million of deferred compensation expense
recorded, approximately $1.0 million was charged to expense during the year
ended December 31, 1998.

    We have incurred significant losses since our inception and we expect to
continue to incur significant losses for the foreseeable future. As of December
31, 1998, we had an accumulated deficit of approximately $10.9 million and
approximately $8.6 million of net operating loss carryforwards for federal
income tax purposes. Our net loss carryforwards begin to expire in 2003.

Three Months Ended March 31, 1999 Compared to Three Months Ended March 31, 1998

 Revenues

    Total revenues increased by $311,000 to $1.1 million for the three months
ended March 31, 1999 from $831,000 for the three months ended March 31, 1998,
an increase of 37%.

    Service Fees. Service fees increased by $152,000 to $735,000 for the three
months ended March 31, 1999 from $583,000 for the three months ended March 31,
1998, an increase of 26%. This increase is primarily attributable to services
provided to new financial institutions implemented in the quarter as well as
increases in revenues from increased volume from current customers of our
Internet bill publishing service and our 1-800-Paybill service. Service fees
represented 64% of total revenues for the three months ended March 31, 1999
compared to 70% for the three months ended March 31, 1998.

    Interest. Interest revenue increased by $159,000 to $407,000 for the three
months ended March 31, 1999 from $248,000 for the three months ended March 31,
1998, an increase of 64%. This increase is primarily attributable to an
increase in the number of transactions per existing customer, higher dollar
amounts associated with each transaction and the addition of new customers.
Interest represented 36% of total revenues for the three months ended March 31,
1999 compared to 30% of total revenues for the three months ended March 31,
1998.

 Operating Expenses

    Total operating expenses increased by $800,000 to $2.2 million for the
three months ended March 31, 1999 from $1.4 million for the three months ended
March 31, 1998.

    Cost of Services. Cost of services consists primarily of data processing
costs, new customer implementation, customer service and technical support, as
well as third party transaction fees like automated clearinghouse transaction
charges associated with wiring funds in performing our services. Cost of
services increased by $125,000 to $555,000 for the three months ended March 31,
1999 from $430,000 for the three months ended March 31, 1998, an increase of
29%. This increase was primarily attributable to the corresponding increase in
revenue, as well as an increase in the number of employees in anticipation of
future growth. Cost of services was 49% of total revenues for the three months
ended March 31, 1999 compared to 52% of total revenues for the three months
ended March 31, 1998.

                                       20

    Development Costs. Development costs consist primarily of salaries for
software engineers and programming personnel. Development costs increased by
$116,000 to $332,000 for the three months ended March 31, 1999 from $216,000
for the three months ended March 31, 1998, an increase of 54%. This increase
was primarily attributable to increases in payroll associated with additional
headcount in anticipation of future growth. Development costs represented 29%
of total revenues for the three months ended March 31, 1999 compared to 26% of
total revenues for the three months ended March 31, 1998.

    Selling, General and Administrative. Selling, general and administrative
expense consists primarily of salaries for sales and marketing personnel and
accounting and administrative personnel, as well as sales commissions and
public relations expense. Selling, general and administrative expense increased
by $429,000 to $1.1 million for the three months ended March 31, 1999 from
$671,000 for the three months ended March 31, 1998, an increase of 64%. This
increase was primarily attributable to an increase in the number of sales and
marketing and administrative personnel in anticipation of future growth.
Selling, general and administrative expense represented 96% of total revenues
for the three months ended March 31, 1999 compared to 81% of total revenues for
the three months ended March 31, 1998.

    Amortization of Deferred Compensation. Amortization of deferred
compensation increased by $196,000 to $230,000 for the three months ended March
31, 1999 from $34,000 for the three months ended March 31, 1998. Deferred
compensation represents the difference between the exercise price of options
granted by us and the fair market value of our common stock on the grant date
of the options in cases where the exercise price was below fair market value on
the grant date. At March 31, 1999, we had $2.4 million of deferred compensation
that will be amortized over the remaining vesting periods of the options, which
range from one to four years.

    Interest Expense. Interest expense consists of interest paid on leased
equipment. Interest expense decreased to $2,100 for the three months ended
March 31, 1999 from $3,700 for the three months ended March 31, 1998.

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

 Revenues

    Total revenues increased by $790,000 to $3.8 million in the year ended
December 31, 1998 from $3.0 million in the year ended December 31, 1997, an
increase of 26%.

    Service Fees. Service fees were relatively unchanged at $2.4 million for
the year ended December 31, 1998 compared to $2.3 million for the year ended
December 31, 1997. Revenue was relatively flat because the increase in revenues
from our 1-800-PayBill service and Internet bill publishing service was offset
by a decrease in revenue from our payment services resulting from some
financial institutions electing to bring these services in-house. Service fees
represented 62% of total revenues for the year ended December 31, 1998 compared
to 77% of total revenues for the year ended December 31, 1997.

    Interest. Interest revenue increased by $737,000 to $1.4 million for the
year ended December 31, 1998 from $699,000 for the year ended December 31,
1997, an increase of 105%. This increase is primarily attributable to an
increase in the use of our Balance Transfer Utility service during 1998 which
generates higher interest revenue because of the higher dollar amounts
associated with this service compared to our other services. Interest revenue
represented 38% of total revenues for the year ended December 31, 1998 compared
to 23% of total revenues for the year ended December 31, 1997.

 Operating Expenses

    Total operating expenses increased by $2.0 million to $7.2 million for the
year ended December 31, 1998 from $5.2 million for the year ended December 31,
1997, an increase of 38%.


                                       21

    Cost of Services. Cost of services increased by $166,000 to $2.0 million
for the year ended December 31, 1998 from $1.8 million for the year ended
December 31, 1997, an increase of 9%. This increase was due primarily to
incremental costs associated with the increased use of our 1-800-PayBill
service and Internet bill publishing service in 1998 compared to 1997. Cost of
services was 52% of total revenues for the year ended December 31, 1998
compared to 59% of total revenues for the year ended December 31, 1997. This
percentage decrease is due to increased revenues during 1998 from our Balance
Transfer Utility service, which generates higher interest revenue without a
significant increase in cost because of the higher dollar amounts associated
with each transaction compared to our other services.

    Development Costs. Development costs increased $75,000 to $895,000 for the
year ended December 31, 1998 from $820,000 for the year ended December 31,
1997, an increase of 9%. This increase was primarily attributable to the
addition of database and software development personnel during the fourth
quarter of 1998. Development costs were 23% of total revenues for the year
ended December 31, 1998 compared to 27% of total revenues for the year ended
December 31, 1997. This percentage decrease resulted from relatively flat
development costs being spread over a larger revenue base in 1998.

    Selling, General and Administrative. Selling, general and administrative
expense increased $746,000 to $3.3 million for the year ended December 31, 1998
from $2.5 million for the year ended December 31, 1997, an increase of 30%.
This increase was primarily attributable to an increase in the number of sales
and marketing and administrative personnel in 1998. Selling, general and
administrative expense was 86% of total revenues for the year ended December
31, 1998 compared to 84% of total revenues for the year ended December 31,
1997.

    Amortization of Deferred Compensation. Amortization of deferred
compensation expense was $1.0 million in the year ended December 31, 1998.
Deferred compensation is being amortized over the respective vesting periods of
the options. At December 31, 1998, we had $867,000 of deferred compensation
that will be amortized over the remaining vesting periods of the options which
range from one to four years.

    Interest Expense. Interest expense consists of interest paid on leased
equipment. Interest expense was relatively unchanged from $16,000 for the year
ended December 31, 1997 to $14,000 for the year ended December 31, 1998.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

 Revenues

    Total revenues increased by $1.2 million to $3.0 million for the year ended
December 31, 1997 from $1.8 million for the year ended December 31, 1996, an
increase of 67%.

    Service Fees. Service fees increased by $701,000 to $2.3 million for the
year ended December 31, 1997 from $1.6 million for the year ended December 31,
1996, an increase of 44%. This increase was primarily attributable to increased
use of our 1-800-PayBill service and our Balance Transfer Utility service in
1997. Service fees represented 77% of total revenues for the year ended
December 31, 1997 compared to 89% of total revenues for the year ended December
31, 1996.

    Interest. Interest revenue increased by $495,000 to $699,000 for the year
ended December 31, 1997 from $204,000 for the year ended December 31, 1996, an
increase of 243%. This increase is primarily attributable to an increase in the
number of transactions processed in 1997 compared to 1996, in addition to an
increase in the dollar volume of transactions processed due to an increase in
use of our Balance Transfer Utility service. Interest revenue represented 23%
of total revenues for the year ended December 31, 1997 compared to 11% of total
revenues for the year ended December 31, 1996.

 Operating Expenses

    Total operating expenses increased by $1.1 million to $5.2 million for the
year ended December 31, 1997 from $4.0 million for the year ended December 31,
1996, an increase of 28%.

                                       22
<PAGE>

    Cost of Services. Cost of services increased by $438,000 to $1.8 million
for the year ended December 31, 1997 from $1.4 million for the year ended
December 31, 1996, an increase of 31%. This increase corresponds to the
increase in revenues generated from increased transaction processing in 1997.
Cost of services was 59% of total revenues for the year ended December 31, 1997
compared to 74% of total revenues for the year ended December 31, 1996. This
percentage decrease is due to increased revenues from our Balance Transfer
Utility service, which generates higher interest revenue without a significant
increase in cost because of the higher dollar amounts associated with each
transaction compared to our other services.

    Development Costs. Development costs remained relatively unchanged at
$820,000 for the year ended December 31, 1997 compared to $834,000 for the year
ended December 31, 1996, due to the consistent number of personnel and payroll
expenses in this department. Development costs were 27% of total revenues for
the year ended December 31, 1997 compared to 45% of total revenues for the year
ended December 31, 1996. The percentage decrease is due to a similar amount of
development costs being spread over a larger revenue base in 1997.

    Selling, General and Administrative. Selling, general and administrative
expense increased by $714,000 to $2.5 million for the year ended December 31,
1997 from $1.8 million for the year ended December 31, 1996, an increase of
40%. This increase is primarily attributable to an increase in payroll expense
resulting from headcount increases in several departments including sales,
accounting and system administration. Selling, general and administrative
expense was 84% of total revenues for the year ended December 31, 1997 compared
to 99% of total revenues for the year ended December 31, 1996.

    Interest Expense. Interest expense increased by $9,000 to $16,000 for the
year ended December 31, 1997 from $7,000 for the year ended December 31, 1996,
an increase of 129%. This increase is attributable to a capital equipment lease
entered into in early 1997.

</TABLE>

    We have experienced year-to-year revenue growth with some seasonal
fluctuations during the second half of the year. These fluctuations relate
primarily to increases in interest revenue derived from our Balance Transfer
Utility service during the last two quarters of the year. These increases
result from direct marketing programs initiated by credit card issuers which
cause increased demand for our Balance Transfer Utility service. The increased
demand in Balance Transfer Utility services causes interest revenue to increase
because of the higher dollar amounts associated with this service compared to
our other services.


                                       24
<PAGE>

    Revenues decreased slightly from the first quarter of 1998 to the second
quarter of 1998 as a result of some financial institutions electing to bring
payment services provided by us in-house. Cost of services as a percentage of
revenue was higher in the second quarter of 1998 than in previous quarters as a
result of increases in payroll expense related to increased headcount during
this quarter. We increased the number of personnel in this quarter in
anticipation of future growth. Selling, general and administrative expense was
also high in this quarter due to increases in sales and marketing expenses
primarily attributable to the addition of personnel and tradeshow expenses
incurred during this quarter.

    In addition to seasonal fluctuations, quarterly results of operations may
be subject to significant fluctuations due to several factors, including:

  . the rate at which we increase our customer base and their use of our
    various services;

  . the amount and timing of costs related to our sales and marketing
    efforts and other initiatives;

  . sales and implementation cycles of our customers;

  . the loss of a number of existing customers;

  . the loss of key employees and time and expense needed to recruit, hire
    and train new personnel, particularly service development personnel;

  . our ability to upgrade, enhance and maintain our systems and
    infrastructure and the timing and costs of this;

  . interest rate fluctuations; and

  . economic conditions which may affect the budgets of billers, financial
    institutions and consumers for technological expenditures.

    We anticipate that our operating expenses will continue to increase
significantly due to development and implementation costs associated with our
Internet bill publishing service. These expenses will relate to personnel
increases and technological expenditures. We expect that revenues will increase
due to biller and consumer adoption of our Internet bill publishing service. If
biller or consumer adoption is slower than expected, revenues may not increase
at the same rate as expenses in the future. If revenues in any quarter do not
increase correspondingly with increases to expenses, our results of operations
for that quarter would be materially and adversely affected. For the foregoing
reasons, we believe that quarter-to-quarter comparisons of our results of
operations are not necessarily meaningful and that our results of operations in
any particular quarter should not be relied upon as necessarily indicative of
future performance.

Liquidity and Capital Resources

    Historically, we have experienced significant operating losses and working
capital deficits. Our working capital deficit was $5.6 million at December 31,
1996 and $7.9 million at December 31, 1997. In September 1998, we sold
2,493,870 shares of our common stock to Billing Concepts for $10.0 million. At
December 31, 1998 our working capital deficit was $308,000 and as of March 31,
1999, our working capital deficit was $823,000.

    Net cash used in operating activities was $3.4 million for both the year
ended December 31, 1998, and the year ended December 31, 1996 and $414,000 for
the three months ended March 31, 1998. For the year ended December 31, 1997 and
the three months ended March 31, 1999, our operating activities generated cash
of $2.5 million and $2.3 million. Cash provided by operating activities in the
three months ended March 31, 1999 was primarily the result of increases in
customer deposits payable. The cash used in operating activities in 1998 was
primarily the result of our net loss and an increase in other current assets,
partially offset by an

                                       25
<PAGE>

increase in accounts payable. For the year ended December 31, 1997, cash
provided by operating activities was primarily attributable to an increase in
customer deposits payable, in addition to increases in accounts payable and
accrued expenses. During 1996, cash used in operating activities was primarily
attributable to our net loss.

    Net cash used in investing activities was $257,000, $373,000 and $298,000
for the years ended December 31, 1998, 1997 and 1996 and $483,000 and $36,000
for the three months ended March 31, 1999 and 1998. This cash was used
primarily for the purchase of computer equipment and software.

    Net cash provided by financing activities was $9.5 million in the year
ended December 31, 1998 and $2.9 million in the year ended December 31, 1996.
Net cash used in financing activities was $2.2 million in the year ended
December 31, 1997. Net cash provided by financing activities was $634,000 and
$585,000 for the three months ended March 31, 1999 and 1998. The cash generated
in the three months ended March 31, 1999 resulted from the net proceeds from
the sale of shares of our common stock in March 1999. The cash generated in
1998 resulted from the net proceeds of $10.0 million from the sale of shares of
our common stock in September 1998, partially offset by decreases in bank
overdrafts and payments on long-term debt. The cash used in 1997 was primarily
due to a decrease in the bank overdraft. The cash generated in 1996 was
primarily attributable to an increase in the bank overdraft.

    We believe that, based on our current business plan, the net proceeds from
this offering and existing cash and cash equivalents will be sufficient to meet
our operating activities, capital expenditures and other obligations for the
next twelve to eighteen months.

Year 2000 Considerations

    Many currently installed computer systems and software products are coded
to accept and recognize only two-digit rather than four-digit entries to define
the applicable year. These systems may recognize a date using "00" as the year
1900 rather than the year 2000. As a result, computer systems and/or software
used by many companies, including our billers and financial institutions upon
which we rely to perform our services, may need to be upgraded to comply with
Year 2000 requirements or risk system failure or miscalculations causing
disruptions of normal business activities.

    State of Readiness. We have completed our assessment of our services and
information technology systems. We believe that our mission critical systems
and a majority of our non-mission critical systems are Year 2000 compliant. We
anticipate that our systems will be Year 2000 compliant by October 1999. We
have also completed our initial survey of the information systems of our
principal vendors and service providers. Based on the oral representations of
these vendors and service providers, we believe that the information technology
systems of these third parties, as they relate to us, do not pose significant
operational issues. We have replaced any of our principal vendors that are
unable to certify that their products are Year 2000 compliant. Our assessment
is on-going and will continue with all principal vendors and service providers
with which we do business. In addition, we do not believe our embedded systems
pose Year 2000 concerns because we believe that we have identified all of our
software and hardware that require Year 2000 updates or modifications.

    Costs. We currently anticipate that our total expenses for Year 2000
compliance will be less than $300,000. As of March 31,1999, we have spent
approximately $130,000 in personnel and other costs related to our Year 2000
risk assessment and remediation efforts.

    Risks. In order to accurately provide our Internet bill publishing service,
we must rely on technology supported by billers, financial institutions,
aggregators, presenters and consumers. Furthermore, our services rely on
transmission of data over the Internet, third party data and voice
communication lines, and data transmission through wire transfer systems,
including the Federal Funds system. Failure by us, our billers, aggregators,
presenters or suppliers to adequately address Year 2000 issues in a timely
manner could impede our ability to provide our services and have a direct
impact on our ability to generate revenue. This, in turn,

                                       26
<PAGE>

could have a material and adverse impact on our business, operating results and
financial condition. Accordingly, we plan to correct our remaining Year 2000
issues by October 1999. We believe that associated costs are adequately
budgeted for in our 1999 business plan. However, if our efforts or the efforts
of billers, aggregators, financial institutions and others with which we engage
in business, fail to adequately address their own Year 2000 issues, the most
likely worst case scenario would be a substantial loss of our revenue for some
period of time.

    Contingency Plan. We are currently developing a contingency plan to address
situations that may result if we are unable to achieve complete Year 2000
compliance by October 1999. We cannot provide any assurance that the plan we
develop will be successful in addressing any remaining Year 2000 issues.

New Accounting Pronouncement

    In March 1998, the American Institute of Certified Pubic Accountants issued
Statement of Position 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use," or SOP 98-1. SOP 98-1 provides
guidance on accounting for computer software developed or obtained for internal
use, including the requirement to capitalize specified costs and amortization
of such costs. We adopted SOP 98-1 in January 1999. The adoption did not have a
material effect on our financial position or results of operations.

Market Risk

    A significant portion of our revenue is generated from interest paid on
amounts deposited overnight with financial institutions pending payment. The
interest earned is based on prevailing short-term interest rates. Accordingly,
fluctuations in short-term interest rates will affect our revenues. Likewise, a
decrease in revenue generated by overnight investment may not be met by a
corresponding decrease in any borrowing costs which we may incur in the future.
Thus, either a fall in prevailing short-term interest rates or an increase in
future borrowing costs could materially and adversely affect our business,
operating results and financial condition. In the future, we may manage our
interest rate risk through interest rate hedging techniques. However, we
currently do not use such techniques and they may not be successful in reducing
or eliminating our interest rate risk in the future.

financial institutions. Our bill publishing services are comprised of both the
presentment and payment of bills. We also provide electronic lockbox and credit
card balance transfer services to large businesses and financial institutions.

    Our telephone bill publishing service enables consumers to access billing
information and to pay bills in as few as five keystrokes and to set up
automatic payment of recurring bills. Our Internet bill publishing service
eliminates the need for billers to generate and mail paper bills. Both our
telephone and Internet services eliminate the need for consumers to write and
mail paper checks. Our Internet bill publishing service allows billers to
publish bills directly through their own web sites or indirectly through web
sites of financial institutions and Internet portals. An Internet portal is a
high-traffic web site that allows people to search, navigate, retrieve
information and access services via the Internet. Using our service, consumers
have numerous options of how, where and when to access, analyze and pay their
bills. Our electronic lockbox service, which is a stand-alone service as well
as a key component of both our telephone and Internet bill publishing services,
is a clearinghouse for electronic consumer-initiated payments. Our credit card
balance transfer service allows electronic transfers of balances from one
credit card institution to another. As of May 31, 1999, of our more than 250
corporate customers, 45 were utilizing our electronic bill publishing services.

Industry Background

 Traditional Paper-Based Billing and Payment Process

    According to Jupiter Communications, in 1998 approximately 15 billion
consumer paper bills were received by approximately 100 million U.S.
households. Most of these are recurring monthly or quarterly bills mailed to
consumers primarily by retailers, utilities and credit card companies. Paper
bills are prepared by either the biller itself or, more often, by an outsourced
bill fulfillment vendor. Creating and distributing a paper bill is a costly
multiple-step process that includes extracting relevant data from the internal
accounts receivable system of the biller, organizing the data into a billing
format, printing and separating the bills, stuffing envelopes, applying postage
and mailing the bill to the consumer. The bill payment process is also costly
and labor intensive. The biller must currently contract with a commercial
lockbox which receives consumer payments. The lockbox vendor opens the payments
and separates checks from the remittance stub. The lockbox vendor also sends
the biller reports which allow the biller to update both its accounts
receivable system and its accounting records. We estimate that the cost to the
biller of preparing and sending a paper bill and receiving and posting a bill
payment ranges from approximately $0.75 to $1.50 per bill. According to Gartner
Group, the average cost to the biller of creating and delivering a paper bill
is $1.00.

    Similarly, the paper-based billing and payment process is time-consuming
and can be costly for the consumer. Jupiter Communications currently estimates
that, during each 12-month period, U.S. households will spend an average of 24
hours on bill management, $46 on postage and $144 on check-writing fees to
handle an average of 12 recurring monthly bills. The graph below depicts the
steps involved in the traditional paper-based billing and payment process:


[GRAPHIC DEPICTING THE 11 STEPS INVOLVED IN THE TRADITIONAL PAPER-BASED BILLING
AND PAYMENT PROCESS APPEARS HERE, WITH THE FOLLOWING TEXT:]

Step 1  Biller prepares the paper bill

        --In-house

        --Out-sourced to bill fulfillment vendors

Step 2  Biller delivers the bill to the post office bulk mail center

Step 3  Post office delivers the bill to the consumer's mailbox

Step 4  Consumer reviews the bill, writes the check, and mails the check and
        payment stub back to the biller

Step 5  Post office delivers the check and payment stub to the biller's mailbox
        or traditional lockbox service

Step 6  Biller or lockbox service opens the envelope, separates the check and
        the payment stub, records the payment and updates the biller's accounts
        receivable system.

        --In-house

        --Out-sourced to traditional lock box service

Step 7  Biller or lockbox service encodes and deposits the check and the bank
        forwards the check to the Federal Reserve

Step 8  The Federal Reserve sorts each individual check and forwards them to the
        consumer's bank

Step 9  For each check, the Federal Reserve debits the account at the consumer's
        bank and credits the reserve account at the biller's bank

Step 10 Consumer's bank account is debited and the biller's bank account is
        credited; the consumer's bank receives the check from the Federal
        Reserve

Step 11 Consumer's bank prepares a monthly statement and sends it with the
        canceled paper checks to the consumer

 Internet Bill Presentment and Payment Process

    In the past, consumers were only able to access basic billing information
and process payments through the use of the telephone. With new technology,
consumers are able to obtain detailed billing information and process payments
through the Internet. These recent advances in technology have provided and
will continue to provide opportunities to dramatically simplify the bill
presentment and payment process, to greatly reduce the cost to the biller and
to improve the convenience for the consumer. The biller compiles relevant data
from its internal accounts receivable database and can either make its billing
information available through its own Internet web site, or indirectly through
Internet web sites of financial institutions and Internet portals. Consumers
are able to access their bill and account information whenever they wish and
may pay bills by clicking a payment symbol on the computer screen. Funds are
electronically transferred from the consumer's bank account, through a payment
network like the Federal Reserve System, to a concentration account of an
electronic lockbox service where all payments to a particular biller are
deposited and transferred to the biller's bank account. Bill and account
information is continuously updated to reflect consumer payments. We estimate
that the total cost to the biller and the consumer for our Internet Bill
Publishing Service ranges from $0.35 to $0.50 per transaction. The graph below
depicts the steps involved in the customary Internet bill presentment and
payment services process:


[GRAPHIC DEPICTING THE 4 STEPS INVOLVED IN THE INTERNET BILL PRESENTMENT AND
PAYMENT SERVICE PROCESS APPEARS HERE, WITH THE FOLLOWING TEXT:]


1 The biller creates an electronic bill with interactive bill analysis and
 one-on-one marking options. This is, either:

 A  Created In-house, or

B  Out-sourced to internet bill publisher

2 The consumer accesses the bill at a web site and initiates payment

3 The payment funds are electronically transferred from the consumer's bank
account to a concentration account of an electronic lockbox service where all
payments to a particular biller are deposited and transferred to the biller's
account.

4 The consumer's bank prepares a monthly statement and sends it to the consumer
or presents it electronically to the consumer.

All the electronic bills for a particular consumer are aggregated and presented
to web sites

         [END OF GRAPHIC]

    The Internet bill presentment process can be viewed as analogous to the
process of creating, distributing and selling books. A number of parties are
potentially involved in this process. The parties involved typically include
the following:

  . Billers: The principal billers are retailers, utilities and financial
    institutions that issue credit cards. Although there are thousands of
    billers, we believe that a large portion of total bills generated are
    produced by a concentrated number of billers. The biller would be
    equivalent to the author in the book publishing analogy.

                                       30
<PAGE>

  . Publishers: The publisher compiles, formats and verifies the information
    in the accounts receivable data base and then creates a bill for
    presentment on the Internet. A publisher may be either the biller itself
    or an entity, like us, that provides an outsourced publishing solution
    for multiple billers. This publishing role is similar to the role of the
    book publisher which takes the content provided by the author and
    packages the book for distribution.

  . Aggregators: An electronic biller may choose to engage one or more
    aggregators which collect consumer bills from numerous publishers and
    sort and present these bills to consumers through the Internet. These
    aggregators enable, through presenters, a consumer to access account
    information regarding multiple billers on a single web site, rather than
    having to go to each individual biller's web site to access account
    information. The aggregator performs a role similar to that of a book
    distributor, which has arrangements with multiple publishers and retail
    outlets to facilitate the distribution of the publishers' books to the
    retail outlets.

  . Presenters: Once an aggregator has received and sorted bills created by
    the publishers, these bills can be presented on the web sites of one of
    two types of presenters: financial institutions or Internet portals.
    These presenters are comparable to the retail outlets and other means by
    which consumers directly purchase books.

    The following chart shows the players involved in the Internet bill
presentment process.

 Growth of the Internet and Internet-based Financial Services

    The Internet has experienced rapid growth and has developed into a
significant tool for global communications and commerce. Advances in online
security and payment mechanisms have encouraged businesses and consumers to
engage in electronic commerce. Forrester Research estimates that sales over the
Internet will increase from $7.8 billion in 1998 to $108 billion in 2003.
Internet-based financial services, like electronic brokerage and banking,
represent a significant portion of the electronic commerce market. The
attractiveness of Internet-based financial services stems in large part from
the speed of conducting financial transactions over the Internet, as well as
the ability of the Internet user to access extensive amounts of information.
Forrester Research estimates that the number of online brokerage accounts will
grow from 3.0 million in 1997 to 14.4 million by the year 2002 and that assets
managed online will reach $688 billion by the year 2002. Similarly, Forrester
Research estimates that online banking will grow from 2.4 million households in
1998 to 18 million in 2002. The Internet is also becoming a more significant
platform for broad consumer-based financial services like insurance, mortgages
and bill presentment and payment.

 Outsourcing Opportunity

    As the use of electronic bill presentment and payment grows, billers
choosing to accommodate customer demands must decide whether to develop
electronic bill presentment and payment capabilities internally or to outsource
the process entirely. Billers that choose to manage their own electronic bill
presentment and payment process may encounter a number of obstacles. To be in a
position to publish and achieve wide distribution of their bills, billers must
purchase, successfully integrate and maintain:

  . software which enables the biller to parse and decode bill data print
    streams;

  . in-house servers which will update and display bill content;

  . automated clearinghouse software which enables the biller to instruct to
    electronically debit consumer accounts;

  . messaging software which enables the biller to communicate with multiple
    aggregators;

  . a dedicated interface with a major bank which enables the biller to
    receive funds and data through automated clearinghouse transactions; and

  . lockbox software which enables the biller to update internal accounts
    receivable files.

    In addition, once billers are capable of publishing and handling payments,
they must then make arrangements with multiple aggregators or presenters that
present bills for multiple billers.

    Many billers lack the expertise to cost-effectively implement, maintain,
scale, enhance and service the hardware and software necessary to provide their
own electronic bill presentment and payment system and to develop and maintain
multiple relationships with aggregators or presenters and financial
institutions. An outsourced solution is attractive to billers because it allows
them to focus on their core competencies and to accelerate the time in which
they can offer electronic bill presentment and payment services to their
customers.

reduce the costs to and administrative burden on billers by eliminating the
need to develop and manage an in-house system and by capitalizing on our
economies of scale and implementation expertise.

    Broad Distribution and Access. Our relationships with multiple aggregators
enable billers using our Internet bill publishing service to publish their
bills through multiple presenters, thereby providing their consumers with
numerous options of where and when to access and/or pay their bills. In
addition, our technology allows consumers to access their bills through the

provide electronic bill presentment and payment to their consumers without
modifications to their existing systems or to their processing and
reconciliation procedures.

The Princeton eCom Strategy

    Our goal is to become a leading provider of Internet bill presentment and
payment services. We plan to achieve this goal by implementing the following
key strategies:

    Further Penetrate Our Existing Customer Base. We believe that our existing
base of billers and financial institutions which do not currently use our
Internet bill publishing and payment service provides substantial opportunities
for expansion of this service. As of May 31, 1999, of our more than 250
corporate customers using our services, 45 were utilizing our electronic bill
publishing services. Of these customers, 14 are currently utilizing our
Internet bill publishing service. We intend to further penetrate this existing
customer base by substantially expanding our sales and marketing efforts and
service offerings.

    Expand Our Sales and Marketing Efforts. We are developing a sales and
marketing plan directed towards the largest billers in the United States that
do not currently use any of our services. To implement this sales and marketing
plan, we are recruiting a number of experienced sales professionals. To date,
we have spent a nominal amount on our sales and marketing efforts. We intend to
substantially increase these expenditures during the next several years. In
addition, we intend to expand our indirect sales channels by establishing
strategic relationships with companies that process paper bills for billers,
which should enable us to gain access to the biller bases of these companies.

    Expand Our Distribution Channels. We intend to expand our distribution
channels by developing relationships with additional aggregators. Because
aggregators rely upon bill publishers with significant biller relationships, we
believe that aggregators will find us more attractive as our biller base
expands. To date, we have relationships with a number of aggregators, including
TransPoint, a Microsoft/First Data Corporation/Citicorp joint venture, and
Intuit.

    Introduce New Services and Service Enhancements. We seek to remain on the
forefront of the developing Internet bill presentment and payment industry by
continuing to develop more advanced services designed to address our customers'
needs. We use customer feedback, including surveys, to design service
enhancements that meet evolving customer needs. Examples of service
enhancements which we have

                                       33
<PAGE>

previously developed include interactive data capability, which enables
consumer-initiated bill analysis on the Internet, one-to-one marketing direct
from the biller to the consumer and electronic commerce transaction capability.
In some circumstances, we also develop specific applications to meet the needs
of particular customers. For example, we developed a system for Sallie Mae that
electronically updates student loan information.

    Pursue Strategic Acquisitions. We intend to pursue strategic acquisitions
that complement our business. We may acquire companies to obtain additional
technologies, billers, services or experienced personnel.

Sales and Marketing

    Historically, our sales and marketing efforts have involved specific face-
to-face meetings with a limited number of potential billers and financial
institutions and we have spent a nominal amount on these efforts. We are
developing a sales and marketing plan directed towards further penetrating our
existing base of billers that do not currently use our Internet bill publishing
and presentment service, while simultaneously targeting the largest billers in
the United States that do not currently use any of our services. To implement
this sales and marketing plan, we are recruiting a number of experienced sales
professionals. We intend to substantially increase our sales and marketing
efforts and expenditures over the next several years. In addition, we intend to
expand our indirect sales channels by establishing strategic relationships with
various financial institutions in order to enable us to gain access to the
biller bases of these companies. We also intend to further develop
relationships with aggregators in order to make our services more attractive to
billers.

    We intend to use a variety of marketing programs to build market awareness
of Princeton eCom and our services and to generate new business. These programs
include:

  .  market research;
  .  service and strategy updates with industry analysts;
  .  public relations activities including press releases and featured news
     articles;
  .  direct mail and relationship marketing;
  .  trade shows;
  .  speaking engagements; and
  .  web site marketing.

Implementation Resources

    Concurrent with our expanded sales and marketing efforts, we intend to
invest additional funds to strengthen our implementation resources. Our
implementation staff is responsible for all aspects of bringing a new customer
online and for resolving any technical issues which may arise. To date, this
process has been designed to meet our current sales volume. Additional
investment in implementation will enable us to meet the requirements of the
additional billers and financial institutions which we anticipate will result
from our expanded sales and marketing efforts. Our additional investment in
implementation resources will focus on additional programming and project
management resources and on new project management software.

Service Development

    We use customer feedback, including surveys, to develop new services as
well as enhancements to our existing services. These new services and
enhancements are designed to meet the evolving needs of our customers. We also
develop, from time to time, specific services and service enhancements to meet
the needs of particular billers and financial institutions.

    Our service development department currently consists of 17 software
developers who have extensive knowledge of, and practical experience with,
systems developed by Sun Microsystems, Microsoft and Oracle. Members of our
development team use hyper-text mark up language (HTML), along with desktop
tools such as Adobe PhotoShop and MicroSoft Image Composer.

    We expense development costs as incurred. In 1998, we spent approximately
$895,000 on service development. We expect to significantly increase
expenditures in this area over the next several years.

Customers

    As of May 31, 1999, we service over 250 billers and financial institutions.
Although only 14 of our customers use both our telephone and Internet bill
publishing services, we intend to continue to cross-market this service to the
balance of our existing customer base. No individual customer accounted for
more than 7% of our total revenues, or 11% of our service fee revenues, for the
three months ended March 31, 1999. The following is a list of our top 40
customers based on revenue for the three months ended March 31, 1999:

Technology

    We have created a proprietary infrastructure by combining internal
expertise with advanced technology.

    We have designed a system which is reliable, flexible, and can be easily
expanded to meet growth demands without significant cost or change. Our system
can handle an increase in transaction volume by simply making additions to the
core components such as data storage, central processing units and other
technological components. As of May 31, 1999, we support over 80 million bills
monthly. Our back-end systems have ample internal redundancy to ensure
reliability 24 hours a day, 7 days a week. Our environment utilizes state-of-
the-art technologies developed by Novell, Oracle, Microsoft, Hewlett Packard
and Sun Microsystems. We employ technology such as mirrored storage devices
and redundant power supplies. As a means of protecting our data we have
employed offsite storage facilities. We recently established a Sungard hot
site in Philadelphia, Pennsylvania where our environment can be mirrored in
the event of an equipment failure or a natural disaster at our Princeton, New
Jersey site.

    We implement industry best practices for data security rather than relying
on any single vendor's solution. Our local and wide area networks are
connected via firewall technology which provides several custom security
services.

    Our network includes three core systems -- our retail, wholesale and
Digital Scanline systems. These systems are based on open standards and
interface with many consumer input and output devices, financial institutions,
payment mechanisms and billing systems. The graph below outlines our
infrastructure as well as the interfaces with other systems:


  [CIRCULAR DIAGRAM APPEARS HERE, SHOWING PRINCETON ECOM'S BILL PUBLISHING AND
 PAYMENT INFRASTRUCTURE AND ITS VARIOUS INTERFACES WITH FINANCIAL INSTITUTIONS
                               AND BILLERS]




                                      37

    Our retail system, which provides for the publishing of bills to consumers
and allows consumers to pay their bills electronically, houses millions of
bills each day from our billers' internal accounting databases. Our real-time
processing engine publishes the data to various devices. We reduce the risk of
technological obsolescence of our system by using device-independent
interfaces. Our retail system interfaces with web servers, interactive
telephony and customer service interfaces.

    Web servers act as an open platform for several forms of communication
through:

  .  Hyper-Text Mark-up Language, or HTML, based Internet bill publishing
     service that allows billers to offer Internet bill presentment and
     payment directly on their own web sites or indirectly on the web sites
     of presenters;

  .  Open Financial Exchange-based communication, or OFX, that allows access
     to Intuit's Quicken and, with some modifications, Microsoft's Money
     personal financial manager programs;

  .  Biller Interface System, BIS, that allows access to aggregators like
     TransPoint; and

  .  Electronic collection systems that allow close integration between us
     and our customers through the deployment of extranets across the web
     using a dual-certificate secure-sockets layer.

    The same technology and data that support our interactive telephony and
customer service systems also support our web servers. This standardization
gives our customers seamless integration across each of our three core systems.
Consequently, a bill paid by any of these methods is immediately reflected on a
bill accessed through any of the other methods.

    Our retail system communicates with aggregators through custom interfaces
designed by us. For example, we have customized software created by TransPoint
to allow us to interface with this aggregator. These custom interfaces allow us
to publish bills and accept payment instructions through aggregators.

    Our wholesale system disburses payments and funds to the billers' bank
accounts through the Federal Reserve System's Fed-wire or automated
clearinghouse system. Private networks are also used to make payments from a
consumer's checking account or credit card as necessary to complete the payment
process. Through els, our wholesale system also conveys both payments and
payment data information electronically to the respective biller, enabling the
biller to update its billing and accounts receivables systems.

    The Digital Scanline system ensures the veracity of data that is
transmitted from the retail system to the wholesale system for payment. Our
technology uses account validation to reduce processing errors and fraud. In
addition, we provide other payment services for financial institutions. These
payments are tested with Digital Scanline before being loaded into our
wholesale database. This process is designed to ensure that every payment
accepted by our wholesale system will post when transmitted to the biller.

Operational Controls

    We have developed our own set of operating procedures and proprietary
processing management applications, controls and practices designed to minimize
transmission and processing related errors. We believe that our current
controls provide reasonable assurance that our processing environment:

  .  is stable;

  .  processes the data promptly and accurately; and

  .  reconciles incoming remittance data and funds with all related outgoing
     data and funds prior to each transmission.

    We use internally developed proprietary reconciliation control applications
that are managed and operated independently from the actual processing
environment. By using this approach we can confirm the accuracy of

                                       38
<PAGE>

the outcome of each transaction on both an aggregate customer level as well as
on an individual transaction basis. Our processes provide us with a real-time
control audit that is independent from any disruptions, disturbances, or
malfunctions of the live processing environment. Trained computer operators are
responsible for ensuring the accuracy of the data input to the system, and for
reconciling the remittance data and monetary transactions to the control
totals. Any reconciliation discrepancies are displayed on monitors and must be
resolved prior to transmission of remittance data and funds to billers and
their banks.

Customer Support

    Our customer support program is designed to provide high quality,
personalized customer support on a timely basis. We strive to achieve this
objective through the use of both internally developed monitoring and training
systems as well as customer surveys which have been designed to identify areas
in need of improvement and solicit ideas for future service needs. We have also
implemented internal procedures that are designed to bring unusual customer
support issues to the attention of senior management. We provide customer
service free of charge for our financial institution customers. In addition, we
offer to our billers, on a fee basis, an outsourcing service whereby we act as
their consumer support operation.

    Billers. Each of our billers is assigned an account representative who
provides a direct point of contact for general inquiries and service requests.
This representative is responsible for coordinating the availability of
appropriate business and technical resources to respond to that particular
biller's service and support requirements. Escalation procedures are designed
to assure the availability of technical personnel on a 24 hour a day, seven
days a week basis. For fast resolution of payment inquiries, we offer some
billers customized on-line customer service interfaces. These interfaces enable
the biller to access real-time payment information that is stored in our
payment disbursement warehouse.

    Financial Institutions. Each of our financial institution customers is
assigned a customer service representative who responds to requests for
information about consumers and payments. This representative provides the
financial institution with documentation regarding payments in sufficient
detail to enable the financial institution to track payment disbursement and
respond to inquiries.

    Consumers. We operate a call center that answers all 1-800-PayBill, els and
Internet Bill Publishing related consumer inquiries. Each of our billers is
offered the opportunity to outsource its customer service function to our
experienced customer service staff.

Competition

    Increased competition in the electronic bill presentment and payment market
could have a material and adverse effect on our business, operating results and
financial condition. We believe that the principal competitive factors are:

  .  ability to identify and respond to customer needs;

  .  technical expertise;

  .  quality of the service;

  .  price of the service;

  .  breadth of distribution; and

  .  possible preexisting relationships between companies that process paper
     bills or lockbox service providers and our potential customers.

    In addition to the foregoing, our Internet bill publishing service also
faces competitive pressures from various third-party software vendors, which
provide some of the software necessary for the development of an integrated,
in-house Internet bill presentment and payment service. In addition, these
companies could

                                       39
<PAGE>

potentially leverage their existing capabilities and relationships to enter the
outsourced Internet bill presentment and payment market.

    Many of our actual and potential competitors have significantly greater
financial, marketing, technical, sales and customer support and other
resources, larger customer bases and longer relationships with customers than
we do. In addition, some of these potential competitors may be able to devote
greater resources to the development, promotion and sale of their services,
adopt more aggressive pricing strategies and devote substantially more
resources to the development of technology and systems development than we are
able to.

    Increased competition may result in reduced operating margins, loss of
market share and diminished value of our services, as well as different
pricing, service and marketing strategies. We may not be able to compete
successfully against current and future competitors, and competitive pressures
we face could have a material adverse effect on our business, operating results
and financial condition.

Proprietary Rights

    We have registered the trademarks Digital Scanline, els Electronic Lockbox
Service, and 1-800-PayBill. We have also applied for registration for the
trademark e-Collect. We protect our intellectual property rights through a
combination of trademark, copyright and trade secrets laws. We cannot assure
you that the steps we have taken to protect our intellectual property rights,
however, will be adequate to deter misappropriation of those rights. We may not
be able to detect unauthorized use of and take appropriate steps to enforce our
intellectual property rights. It may also be possible for unauthorized third
parties to copy certain portions of our proprietary information or reverse
engineer the proprietary information utilized in our services.

    In order to limit access to and disclosure of our proprietary information,
all of our employees are subject to confidentiality and invention assignment
arrangements, and we enter into nondisclosure agreements with third-parties
with whom we do business. We cannot assure you that these arrangements or other
steps we have taken or will take in the future will be sufficient to protect
our technology from infringement or misappropriation or deter independent
development of similar or superior technologies by others.

    Many parties are actively developing Internet billing and telephone
analysis systems technologies. We expect these developers to continue to take
steps to protect these technologies, including seeking patent protection. For
example, we are aware that a number of patents have been issued in the areas of
web-based information indexing and retrieval, online direct marketing and
telephone statistical analysis systems. As a result, we believe that disputes
over the ownership of these technologies are likely to arise in the future. We
anticipate that additional third-party patents will be issued in the future. We
cannot be certain that our services do not infringe valid patents, copyrights
or other intellectual property rights held by third parties.

    Furthermore, we cannot assure you that third parties will not claim that we
have infringed upon their patents or other proprietary rights. From time to
time, we expect to be subject to claims by third parties in the ordinary course
of our business, including claims of alleged infringement of trademarks,
copyrights and other intellectual property rights of third parties. Although
there has not been any litigation relating to these claims to date, these
claims and any resultant litigation, should they occur, would subject us to
significant liability for damages and would result in the invalidation of our
proprietary rights. In addition, even if we prevail the litigation could be
time-consuming and expensive to defend and could result in diversion of our
time and attention, any of which would materially and adversely affect our
business, operating results and financial condition. Any claims or litigation
from third parties may also result in limitations on our ability to use the
trademarks and other intellectual property subject to these claims or
litigation, unless we enter into agreements with the third parties. However,
these agreements may be unavailable on commercially reasonable terms, or at
all.

Government Regulation

    Our management believes that we are not required to be licensed by the
Office of the Comptroller of the Currency, the Federal Reserve Board, or other
federal or state agencies that regulate or monitor banks or other types of
providers of electronic commerce service. We may, however, be periodically
audited by banking authorities since we are a supplier of services to financial
institutions. We cannot assure you that a federal or state agency will not
attempt, either now or in the future, to require that providers of services
like ours be licensed. This would impede our ability to do business in the
regulator's jurisdiction. A number of states have legislation regulating or
licensing check sellers or money transmitters, which may require us to register
under such legislation in specific instances. Management does not believe that
any state or federal legislation of this type would materially affect our
business. We may be subject to audit or examination under any of the foregoing
requirements. Violations by us of these requirements could limit or restrict
our access to the payment clearance systems or our ability to obtain access to
such systems from banks. Further, the Federal Reserve rules provide that we can
only access the Federal Reserve's automated clearinghouse system through a
bank. If the Federal Reserve rules were to change to further restrict access to
the automated clearinghouse system or limit our ability to provide automated
clearinghouse transaction processing services, our business would be materially
and adversely affected.

    In conducting various aspects of our business, we are subject to laws and
regulations relating to commercial transactions generally, such as the Uniform
Commercial Code, and are also subject to the electronic funds transfer rules
embodied in Regulation E issued by the Federal Reserve Board. The Federal
Reserve's Regulation E implements the Electronic Fund Transfer Act, which was
enacted in 1978. Regulation E protects consumers engaging in electronic
transfers, and sets forth basic rights, liabilities and responsibilities of
consumers who use electronic money services and of financial institutions that
offer these services. For us, Regulation E sets forth disclosure and
investigative procedures. For consumers, Regulation E establishes procedures
and time periods for reporting unauthorized use of electronic money transfer
services and limitations on the consumer's liability if the notification
procedures are followed within prescribed periods. Such limitations on the
consumer's liability may result in liability to us.

    Given the expansion of the Internet commerce market, it is possible that
the Federal Reserve might revise Regulation E or adopt new rules for electronic
funds transfer affecting users other than consumers. Because of growth in the
Internet commerce market, Congress has held hearings on whether to regulate
providers of services and transactions in the Internet commerce market. It is
possible that Congress or individual states could enact laws regulating the
Internet commerce market. If enacted, these laws, rules, and regulations could
be imposed on our business and industry and could have a material adverse
effect on our business, operating results and financial condition. Federal,
local and state laws and regulations may be adopted in the future to address
issues like:

  .  user privacy;

  .  pricing;

  .  online content regulation;

  .  taxation; and

  .  the characteristics and quality of online products and services.

    Any new laws or regulations relating to the Internet could have a material
and adverse effect on our business, operating results and financial condition.

Legal Proceedings

    We are not involved in any material legal proceeding nor are we aware of
any threatened legal action. We are involved, from time to time, in litigation
incidental to the conduct of our business. We believe that any potential
adverse determination in such litigation will not have a material and adverse
effect on our business, operating results and financial condition.

Employees

    As of May 31, 1999, we had 95 employees, employed in implementation, sales
and marketing, service development, finance and administration. We have never
experienced a work stoppage and none of our employees is represented by a labor
union. Except for certain members of management who will execute employment
agreements prior to the closing of this offering, our employees work on an at-
will basis. We consider our relations with our employees to be good.

Facilities

    We currently lease approximately 11,000 square feet of space at our
headquarters in Princeton, New Jersey under a lease that expires on August 31,
2002. We believe that our existing facility is adequate for our current needs
and that suitable additional space will be available, on acceptable terms, when
additional space is needed.

has notified Mr. Holmes of its decision to terminate its investigation of

expected retirement from PricewaterhouseCoopers LLP at the end of June 1999.
Mr. Jennings served as one of our directors from September 1998 until March 15,

PricewaterhouseCoopers LLP's current policy regarding the ability of its
partners to serve as directors of for-profit companies. Mr. Jennings has served
with predecessors of PricewaterhouseCoopers LLP from 1964 to 1985 and from 1992

served as Executive Vice President and Chief Financial Officer of Banker's
Trust. From 1985 to 1988, Mr. Jennings served as Senior Executive Vice
President, Administration of Shearson Lehman Brothers.

Board of Directors and Committees

    Our Board is divided into three classes of directors serving staggered
three-year terms. As a result, approximately one-third of our board is elected
each year. Currently, the term of office of Messrs. Corl and Simmons expires at
the annual meeting of stockholders to be held in 2000 and the term of office of
Messrs. Licciardello and Holmes expires at the annual meeting to be held in the
year 2001. The director up for election at the 1999 annual meeting is currently
vacant. Our staggered board, together with advanced notice procedures which
will be added to our by-laws prior to the completion of this offering, may
deter a stockholder from removing incumbent directors and filling vacancies
with the stockholder's own nominees in order to gain control of our board. See
"Description of Capital Stock -- Certificate of Incorporation and By-law
Provisions."

    We have established a compensation committee which reviews and approves the
compensation and benefits for our key executive officers, administers our
employee benefit plans and makes recommendations to our board regarding such
matters. The compensation committee currently consists of Messrs. Holmes and
Mr. Simmons.

    We will establish an audit committee, consisting of at least two
independent directors, within 90 days following the completion of this
offering. Our audit committee will be responsible for reviewing our audited
financial statements and accounting practices, and considering and recommending
the employment of, and approving the fee arrangements with, independent
accountants for both audit functions and for advisory and other consulting
services.

Compensation Committee Interlocks and Insider Participation

    Prior to October 20, 1998, our board did not have a compensation committee
and all compensation decisions were made by the full board. Messrs.
Licciardello and Corl did not participate in board deliberations with respect
to their individual compensation. Subsequent to October 20, 1998, the
compensation committee has made compensation decisions with respect to our key
executive officers, including the Chief Executive Officer and the President.
None of our executive officers serves as a member of the board of directors or
compensation committee of any entity that has one or more of its executive
officers serving as a member of our board or compensation committee. Our
compensation committee currently consists of Messrs. Holmes and Mr. Simmons.

Director Compensation

    Employee directors do not receive compensation for their service on our
board. Non-employee directors are awarded 10,000 stock options under our Non-
Employee Director Plan for each year of service on our board. See "--Non-
Employee Director Plan."

Executive Compensation

    The following table sets forth the compensation paid, earned or accrued for
all services rendered to us in all capacities during the year ended December

                          Option Grants in Fiscal 1998

- --------
(1) We granted options to purchase a total of 1,225,500 shares of common stock
    during the fiscal year ended December 31, 1998.
(2) Amounts reported in these columns represent amounts that may be realized
    upon exercise of options immediately prior to the expiration of their term
    assuming the specified compounded rates of appreciation (0%, 5% and 10%) on
    our common stock over the term of the options. These assumptions are based
    on rules promulgated by the SEC and do not reflect our estimates of future
    stock price appreciation. Actual gains, if any, on the stock option
    exercises and common stock holdings are dependent on the timing of the
    exercise and the future performance of our common stock. We cannot assure
    you that the rates of appreciation assumed in this table can be achieved or
    that the amounts reflected will be received by the option holder.
(3) Options to purchase 30,000 shares of common stock vested on October 20,
    1998 and options to purchase an additional 30,000 shares of common stock
    will vest on each anniversary thereafter.
(4) These options vest and become fully exercisable as to 25% on the first
    anniversary of the date of grant and as to an additional 25% on each
    anniversary thereafter until all these options are fully vested and
    exercisable.

Year-End Option Values

    The following table sets forth information concerning the number and year
end value of unexercised options held by each of the officers named in the
Summary Compensation Table at December 31, 1998. None of the Named Executive
Officers exercised stock options or stock appreciation rights in the year ended
December 31, 1998.

Stock Option Plan

    Our Amended 1996 Stock Option Plan, which became effective on July 1, 1996
and was amended in December 1998, provides for the granting of incentive stock
options intended to qualify under Section 422 of the Internal Revenue Code
("incentive stock options"), and stock options not intended to qualify as
incentive stock options ("non-qualified stock options"). All of our officers,
key employees and consultants are eligible to participate in the Stock Option
Plan. The total number of shares of common stock which we may issue under the
Stock Option Plan is 4,500,000. Under present law, incentive stock options may
only be granted to our employees and employees of our subsidiaries.

    The Stock Option Plan is administered by our compensation committee which
has the authority to:

  . construe and interpret the plan;

  . create, amend and rescind rules and regulations for the plan;

  . determine the individuals entitled to participate in the plan;

  . determine the timing of specific option grants, the number of options to
    be granted, the vesting schedule for the options and their exercise
    price;

  . determine whether the options granted will be incentive stock options or
    non-qualified stock options; and

  . make all other determinations which may be necessary or advisable for
    the administration of the plan.

    Our compensation committee may grant options at an exercise price less
than, equal to or greater than the fair market value of our common stock on the
date of grant. Under present law, incentive stock options and options intended
to qualify as performance-based compensation for purposes of Section 162(m) of
the Internal Revenue Code, may not be granted at an exercise price less than
the fair market value of our common stock on the date of grant or less than
110% of the fair market value of our common stock in the case of incentive
stock options granted to optionees holding more than 10% of our voting power.
Incentive stock options may not be assigned or transferred during the lifetime
of the holder except as may be required by law. The maximum term of each stock
option granted under the Stock Option Plan to persons other than 10%
stockholders is ten years from the date of grant.

    The Stock Option Plan permits the optionee to determine how they will pay
the exercise price of their options. The plan provides that the option price
may be paid:

  . in cash;

  . with shares of common stock valued at the fair market value of the
    common stock on the date of exercise;

  . in cash by a broker-dealer to whom the holder of the option has
    submitted an exercise notice consisting of a fully endorsed option;

  . through the surrender of options then exercisable valued at the excess
    of the aggregate fair market value of the common stock subject to such
    option on the date of exercise over the aggregate option price of such
    common stock;

  . by directing us to withhold such number of shares of common stock
    otherwise issuable upon exercise of the option having an aggregate fair
    market value on the date of exercise equal to the exercise price of the
    option; or

  . by some other method of payment as may be authorized by our compensation
    committee or any combination of the foregoing payment options as our
    compensation committee may permit in its sole discretion.


                                       48
<PAGE>

    No incentive stock option awards may be granted under the Stock Option Plan
after June 30, 2006. Our compensation committee may, at any time, terminate,
suspend or modify the Stock Option Plan, except that no amendment or revision
may, unless appropriate stockholder approval is obtained, increase the maximum
number of shares of common stock in the aggregate for which we may grant
options under the Stock Option Plan, change the minimum purchase price of an
incentive stock option, increase the maximum term of an incentive stock option,
or grant options to persons not then currently contemplated by the plan. In
addition, no termination, suspension or modification of the Stock Option Plan
may adversely affect any right acquired by an optionee before the date of any
termination, suspension or modification without the optionee's consent.

    The Stock Option Plan provides that outstanding options vest in their
entirety and become exercisable in the event we undergo a change of control. A
change of control will be deemed to occur if:

  . a person or group becomes the beneficial owner of more than 50% of the
    total voting power of our outstanding stock; or

  . there occurs a change in the majority of the members of our board from
    one year to the next, except any changes approved by the former board of
    directors.

    As of May 31, 1999, there were (1) outstanding options under the Stock
Option Plan to purchase an aggregate of 2,442,900 shares of common stock at a
weighted average price of $2.06, (2) outstanding options under the Stock Option
Plan to purchase an aggregate of 350,100 shares of common stock at the initial
public offering price, and (3) 1,636,050 additional shares of common stock
reserved for future option grants.

    As soon as practicable following completion of this offering, we intend to
file with the SEC a registration statement on Form S-8 covering the shares of
common stock underlying options granted and reserve for future issuance under
the Stock Option Plan.

Non-Employee Director Plan

    Our 1998 Non-Employee Director Plan, which was approved by our board on
October 20, 1998 and became effective on October 20, 1998. It provides for the
grant of non-qualified stock options to our directors. The Director Plan
provides for the issuance of up to 600,000 shares of common stock upon exercise
of options.

    Under the terms of the Director Plan, each non-employee director who was a
director on the date the plan went into effect received options to purchase a
number of shares of common stock equal to the product of the number of years he
was elected to serve as a director multiplied by 10,000. These options vest as
to 10,000 shares on the date of grant and on each of the first two
anniversaries of the date of grant, subject to a maximum of two anniversaries.
Further, non-employee directors are also entitled to receive on the first
business day after each of our annual meetings of stockholders at which the
director is re-elected to the board options to purchase an additional number of
shares equal to the number of years he or she is elected to the Board
multiplied by 10,000. These options would vest under the same terms discussed
above. In addition to the automatic grants provided by the plan, non-employee
directors may also receive additional grants of options at the discretion of
our compensation committee. The exercise price of each option under the
Director Plan, other than options granted on October 20, 1998, will be 100% of
the fair market value of our common stock on the date of grant. Each option
will have a term of six years.

    The Director Plan provides that outstanding options vest in their entirety
and become exercisable in the event we undergo a change of control. For
purposes of the Director Plan, change in control has the same meaning given
such term in the Stock Option Plan.

    The exercise price may be paid in cash or with shares of common stock
valued at the fair market value of the stock on the exercise date.


                                       49
<PAGE>


    As of May 31, 1999, there were outstanding options under the Director Plan
to purchase an aggregate of (1) 195,000 shares of common stock at a weighted
average price of $0.03 and (2) 375,000 additional shares of common stock
reserved for future option grants.

    As soon as practicable following the completion of this offering, we also
intend to file a Registration Statement on Form S-8 covering the shares of
common stock underlying options granted, or to be granted, under the Director
Plan.

401(k) Plan

    Our employees participate in our 401(k) profit sharing plan, a defined
contribution plan intended to qualify under Section 401 of the Internal Revenue
Code. All personnel who have completed one year of service with us are eligible
to participate and may enter the plan as of the first day of January or July.
Participants may make pre-tax contributions to the plan of up to 15% of their
eligible earnings, subject to a statutorily prescribed annual limit. We may
make matching contributions on a discretionary basis to the plan. Each
participant is fully vested in his or her contributions, and any investment
earnings thereon. Contributions by the participants or us, and the income
earned on such contributions, are generally not taxable to the participants
until withdrawn. Contributions by us, if any, are generally deductible by us
when made. Contributions are held in trust as required by law. Individual
participants may direct the trustee to invest their accounts in authorized
investment alternatives. In 1998, we did not make any matching contributions.
In 1999, we have begun to match 100% of all employee contributions up to 6% of
that employee's annual base salary.

Employment Agreements

    We have entered into an employment agreement with Mr. Averett pursuant to
which Mr. Averett has agreed to serve full time as our President and Chief
Operating Officer until March 30, 2003, unless earlier terminated in accordance
with the terms of his agreement. Mr. Averett's annual base salary under the
agreement is $200,000 per year. In addition, Mr. Averett was granted options to
purchase 300,000 shares of our common stock at $5.33 per share, which options
will vest as to 25% on each anniversary. Mr. Averett's employment agreement
also provides for vacation and reimbursement of business-related expenses.

    In addition, we have entered into an employment agreement with Mr. Sugden,
pursuant to which Mr. Sugden has agreed to serve full time as our Vice
President and Chief Financial Officer until February 15, 2003, unless earlier
terminated in accordance with the terms of his agreement. Mr. Sugden's annual
base salary under the agreement is $100,000 per year. In addition, under the
terms of his agreement Mr. Sugden was granted options to purchase 150,000
shares of our common stock at $4.00 per share, which options vest as to 25% on
each anniversary, and will be entitled to receive bonuses based on the
achievement of performance goals. Mr. Sugden's employment agreement also
provides for vacation and reimbursement of business-related expenses.

    Pursuant to each employment agreement, if the executive is terminated for
"cause," as defined within the employment agreements, we will be required to
pay the executive, within ten days following this termination, any unpaid base
salary accrued through the date of termination and we will be required to
reimburse the executive for reasonable business expenses incurred prior to that
date. If we terminate Mr. Averett's employment without cause, we will be
required to pay him any unpaid base salary accrued through the date of
termination, plus an additional $200,000 (or $400,000 if he terminates his
employment as a result of a change in control). For purposes of the employment
agreements, a change in control has the same meaning as in the Stock Option
Plan. If we terminate Mr. Sugden's employment without cause, we will be
required to pay him any unpaid base salary accrued through the date of
termination, plus three months salary, at the then current rate, and his
options will vest as if his termination date was twelve months after the actual
termination date. After termination of Mr. Sugden's employment, he will be
entitled to exercise his exercisable options for a fifteen day period. We will
be required to reimburse Mr. Averett and Mr. Sugden for reasonable business
expenses incurred prior to the date of termination. We will be required to pay
the executives their unpaid base salary within 30 days following a termination
without cause, but can, at our option, pay Mr. Averett amounts in

                                       50
<PAGE>

excess of his base salary in equal monthly installments over the 12-month
period following the date of termination and pay Mr. Sugden amounts in excess
of his base salary in equal installments over three months.

    Each of Messrs. Averett and Sugden's employment agreements also provides
that the executive will not, during a one year period after termination,
without our prior written consent, directly or indirectly conduct or engage in
or be associated with any person or entity which conducts or engages in
electronic bill payment, electronic bill publishing or electronic bill
presentment. Each of the employment agreements also provides that the
executives shall not disclose confidential information and may not interfere
with, disrupt or attempt to disrupt the relationship, contractual or otherwise,
between us or any of our subsidiaries and our respective customers or
employees.

                              CERTAIN TRANSACTIONS

Stock Purchases

    In September 1998, we sold 2,493,870 shares of our common stock to Billing
Concepts, a publicly traded corporation with stock listed on the Nasdaq Stock
Market, for an aggregate purchase price of $10.0 million. Under the terms of
the stock purchase agreement for this sale, the parties agreed, among other
things, that (1) in the event that Billing Concepts desires to sell its shares
of common stock, we have a right of first refusal to purchase such shares, (2)
in the event that we offer, sell or grant any option to purchase or otherwise
dispose of any of our equity-equivalent securities or promissory notes in a
transaction intended to be exempt or not subject to registration under the
Securities Act of 1933, except under any employee, officer or director stock
option plan or through mergers or acquisitions not designed to raise capital
approved by our stockholders, Billing Concepts shall have a right of first
refusal to purchase such securities, and (3) Billing Concepts has the right, so
long as it owns at least 10% of our common stock, to have two representatives
on our board of directors. In addition, the agreement provides that if our
working capital deficit at June 30, 1998 was in excess of $8.5 million, then
Billing Concepts had a right to purchase additional shares of our common stock
at a price of $4.01 per share. As a result of our June 30, 1998 working capital
deficit having exceeded $8.5 million, on March 30, 1999, we sold 134,376 shares
of common stock to Billing Concepts for $538,848. In connection with its
acquisition of our stock, Billing Concepts entered into a voting agreement with
Mr. Licciardello, our Chairman and Chief Executive Officer. Under the terms of
this voting agreement, as amended, Mr. Licciardello, the Donald Licciardello
Family Limited Partnership and Billing Concepts have agreed to vote all of
their respective shares of common stock to elect to our board the two
individuals designated by Billing Concepts and three members designated by Mr.
Licciardello. As a result of this voting agreement, Billing Concepts has
appointed two of its executive officers, Parris H. Holmes, Jr. and Kelly E.
Simmons, to serve as directors on our board. In addition, Mr. Licciardello and
the Donald Licciardello Family Limited Partnership agreed to have any
transferee or purchaser of any of their shares of common stock become a party
to the voting agreement, other than purchasers pursuant to sales in a
registered public offering or under Rule 144. The voting agreement
automatically terminates when Billing Concepts ceases to own 10% of our issued
and outstanding common stock. The total number of shares covered by the voting
agreement is 9,620,970.


Guarantee of Loan to Donald C. Licciardello

    Until March 26, 1999, some of our certificates of deposit were pledged as
collateral for a guarantee we issued in connection with a loan obtained by Mr.
Licciardello. On March 26, 1999, the collateral and our guarantee were released
by First Union National Bank.

Loan to C. Richard Corl

    Mr. Corl issued to us a demand note evidencing the outstanding purchase
price for shares of our common stock purchased by him in June 1996. This demand
note, in the amount of $210,308, bears interest at a rate of 6% annually.

shares of preferred stock, $0.01 par value per share. As of May 31, 1999, there
were outstanding (1) 11,344,002 shares of our common stock held of record by 27
stockholders and (2) options to purchase an aggregate of 2,988,000 shares of

Common Stock

    Holders of our common stock are entitled to one vote per share on all
matters on which the holders of common stock are entitled to vote and do not
have cumulative voting rights. This means that the holders of more than 50% of
our shares of common stock voting for the election of directors can elect all
of the directors up for election if they choose to do so; if this event occurs,
the holders of the remaining holders of shares of our common stock will not be
able to elect any person to our board. Subject to rights of any holders of any
shares of our preferred stock, holders of our common stock are entitled to
receive ratably such dividends as may be declared by our board from time to
time out of funds legally available for this purpose. See "Dividend Policy."
Holders of our common stock are not entitled to any preemptive, conversion,
redemption, subscription or similar rights. In the event of a liquidation,
dissolution or winding-up of Princeton eCom, whether voluntary or involuntary,
holders of our common stock are entitled to share ratably in our assets legally
available for distribution, if any, remaining after the payment or provision
for the payment of all of our debts and other liabilities and the payment and
setting aside for payment of any preferential amount due to any holders of any
shares of our outstanding preferred stock. All of our outstanding shares of
common stock are, and all of our shares of common stock offered in this
offering when issued will be, upon payment, duly and validly issued, fully paid
and nonassessable. The rights, preferences and privileges of holders of our
common stock are subject to, and may be adversely affected by, the rights of
the holders of any series of our preferred stock which our board may designate
and issue in the future.

    Our common stock has been approved for listing on the Nasdaq National
Market under the trading symbol ECOM.

    The transfer agent for our common stock is Continental Stock Transfer &
Trust Company.

Preferred Stock

    Prior to completion of this offering, our certificate of incorporation will
be amended to authorize our board to issue, from time to time and without any
further action of our stockholders, up to 3,000,000 shares of preferred stock,
in one or more series. The board will be authorized to fix or alter the
designations, preferences, rights and any qualifications, limitations or
restrictions of the shares of each of these series, including the voting
rights, dividend rights, dividend rates, conversion rights, terms of
redemption, redemption price or prices, liquidation, preferences and the number
of shares constituting any series or designations of these series. The issuance
of preferred stock, while providing flexibility in connection with possible
acquisitions and other corporate purposes could, among other things, have the
effect, under certain circumstances, of delaying, deferring or preventing a
change in control of Princeton eCom. We have no current plan to issue any
shares of our preferred stock. See "--Authorized But Unissued Shares."

Anti-Takeover Effects of Certain Provisions of Delaware Law

    We are subject to the provisions of Section 203 of the Delaware General
Corporation Law, or the DGCL. Section 203 of the DGCL generally prohibits a
publicly-held Delaware corporation from engaging in a

                                       54
<PAGE>

"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an
interested stockholder, unless the interested stockholder attained that status
with the approval of the board 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, fifteen percent (15%) or more of a corporation's voting stock. This
statute could prohibit or delay the accomplishment of mergers or other takeover
or change in control attempts with respect to us and, accordingly, may
discourage attempts to acquire us.

Certificate of Incorporation and By-law Provisions

    Our by-laws currently divide the board into three classes with staggered
three year terms. This classified board could make it more difficult for a
third party to acquire, or discourage a third party from acquiring, control of
us. Our by-laws also currently authorize our board to fill vacant directorships
or increase the size of the board. This may deter a stockholder from removing
incumbent directors and simultaneously gaining control of the board by filling
the vacancies created by that removal with its own nominees. See "Management."

    Prior to completion of this offering, our certificate of incorporation and
by-laws will be amended to include the provisions described in the following
paragraphs, which are intended to further enhance the likelihood of continuity
and stability in the composition of the board and which may have the effect of
delaying, deterring or preventing a future takeover or change in control of us
unless such takeover or change of control has been approved by our board.

    Advanced Notice Provisions for Stockholder Proposals and Director
Nominations. Our by-laws will be amended to establish advance notice procedures
with regard to the nomination, other than by or at the direction of the board,
of candidates for election as directors and with regard to some matters to be
brought before an annual meeting of stockholders. In general, these provisions
will require that notice be received by us not less than 120 days prior to the
meeting and must contain specified information concerning the persons to be
nominated or the matter to be brought before the meeting and concerning the
stockholder submitting the proposal.

    Stockholder Action; Special Meeting of Stockholders. Our by-laws will also
be amended to provide that stockholders may not take action by written consent,
but only at duly called annual or special meeting of stockholders. Our by-laws
will further be amended to provide that special meetings of our stockholders
may be called only by our Chairman of the Board, a majority of the directors or
a holder of a majority of our outstanding stock.

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

Limitation of Liability and Indemnification of Directors

    Our amended and restated certificate of incorporation provides that, except
to the extent prohibited by the DGCL, our directors shall not be personally
liable to us or our stockholders for monetary damages for any breach of
fiduciary duty as a director. Under the DGCL, our directors have a fiduciary
duty to us that is not eliminated by this provision of our amended and restated
certificate of incorporation and, in appropriate circumstances, injunctions and
other nonmonetary relief will remain available. This provision also does not
affect the directors' responsibilities under any other laws, including the
Federal securities laws or state or Federal environmental laws.

                                       55
<PAGE>

    Section 145 of the DGCL enables 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. However, this provision
does not eliminate or limit the liability of a director:

  . for any breach of the director's duty of loyalty to the corporation or
    its stockholders;

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

  . for payments of dividends or approval of stock repurchases or
    redemptions that are prohibited by the DGCL; or

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

    Our by-laws provide that we may 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 proceeds, whether civil, criminal, administrative or
investigative, by reason of the fact that the person is or was one of our
directors, officers, employees or agents or is or was serving at our request as
a director, officer, employee or agent 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 that person in connection with
any threatened, pending or completed action, suit or proceeding.

    We intend to enter into indemnification agreements with our directors and
executive officers. We believe that the provisions of our by-laws and these
indemnification agreements are necessary to attract and retain qualified
directors and executive officers. We intend to secure insurance on behalf of
any officer, director, employee or other agent for any liability arising out of
his or her actions, regardless of whether the DGCL would permit
indemnification.

    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent for which indemnification will be required
or permitted under our by-laws. We are not aware of any threatened litigation
or proceeding that may result in a claim for indemnification.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Upon completion of this offering, we will have outstanding an aggregate of
14,344,002 shares of common stock, assuming no exercise of the underwriter's
over-allotment option and no exercise of outstanding options. Of these shares,
all of the shares sold in this offering will be freely tradable without
restriction or further registration under the Securities Act of 1933, except
that shares purchased by our affiliates, as that term is defined in Rule 144
under the Securities Act of 1933, may generally only be sold in compliance with
the limitations of Rule 144 described below.

Sales of Restricted Securities

    The remaining shares of our common stock are deemed "restricted securities"
under Rule 144. Of the restricted securities, approximately        shares of
common stock, which are not subject to lock-up agreements with the
representatives for the underwriters, will be eligible for immediate sale in
the public markets pursuant to Rule 144(k) under the Securities Act of 1933.
Approximately an additional        shares of common stock, which are not
subject to any lock-up agreement, will be eligible for sale in the public
market in accordance with Rule 144 or Rule 701 under the Securities Act of 1933
beginning 90 days from the date of this prospectus. Upon expiration of the
lockup agreements, approximately        additional shares of common stock will
be available for sale in the public markets in accordance with the provisions
of Rule 144.

                                       56
<PAGE>

Rule 144 and Rule 701

    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person, including one of our affiliates, who has
beneficially owned his or her restricted securities for at least one year from
the later of the date such securities were acquired from us or, if applicable,
one of our affiliates, is entitled to sell, within any three-month period, a
number of shares that does not exceed the greater of:

  . 1% of our then outstanding shares of common stock, which will equal
    approximately 143,440 shares immediately after this offering; or

  . the average weekly trading volume of our common stock on the Nasdaq
    National Market during the four calendar weeks preceding the sale.

    Sales under Rule 144 are also subject to certain requirements concerning
the availability of public information, manner of sale and notice. In addition,
under Rule 144(k), if a period of at least two years has elapsed between the
later of the date the restricted securities were acquired from us or, if
applicable, one of our affiliates, a stockholder who is not an affiliate at the
time of sale and has not been one of our affiliates for a period of three
months prior to the sale is entitled to sell the shares immediately without
compliance with the foregoing requirements of Rule 144.

    Securities issued in reliance on Rule 701 prior to the completion of this
offering, like shares of common stock acquired pursuant to the exercise of
stock options issued by us, are also restricted securities and, beginning 90
days after the date of this prospectus is a part, may be sold by stockholders
who are not affiliates subject only to the manner of sale provisions of Rule
144 and by affiliates under Rule 144 without compliance with the one-year
holding period requirement of the rule.

Stock Options

    Immediately following this offering, we intend to file registration
statements on Form S-8 under the Securities Act of 1933 to register all shares
of common stock issuable under the Stock Option Plan and the Directors Plan.
Shares issued upon exercise of stock options granted under the Stock Option
Plan and the Directors Plan after the effective date of the Form S-8
registration statements will be eligible for resale in the public markets
without restriction, subject to Rule 144 limitations applicable to affiliates
and subject to the lock-up agreements discussed above.

Effect of Sales of Shares

    Prior to this offering, there has been no public trading market for our
common stock, and no prediction can be made as to the effect, if any, that
market sales of shares of common stock or the availability of shares for sale
will have on the market price of our common stock prevailing from time to time.
Nevertheless, sales of significant numbers of shares of our common stock in the
public markets could adversely affect the market price of our common stock and
could impair our ability to raise capital through an offering of our equity
securities.

    The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at that price less
a concession of not in excess of $    per share, of which $    may be reallowed
to other dealers. After this offering, the public offering price, concession,
and reallowance to dealers may be reduced by the representatives. No reduction
shall change the amount of proceeds to be received by us as set forth on the
cover page of this prospectus. The common stock is offered by the underwriters
as stated in this prospectus, subject to receipt and acceptance by them and
subject to their right to reject any order in whole or in part.

    The following table summarizes the compensation to be paid to the
underwriters by us:

    Princeton eCom estimates that expenses payable by us in connection with
this offering, other than the underwriting discounts and commissions referred
to above, will be approximately $1,200,000, including $100,000 being paid to
First Union Capital Markets Corp. as an advisory fee.

    DLJdirect Inc., an affiliate of Donaldson, Lufkin & Jenrette Securities
Corporation and a member of the selling group, is facilitating the distribution
of the shares sold in this offering over the Internet. The underwriters have
agreed to allocate a limited number of shares to DLJdirect Inc. for sale to its
brokerage account holders. DLJdirect Inc. is a broker/dealer registered with
the SEC, the NASD and the various states. It conducts the majority of its
business in an "on-line" environment. At the time DLJdirect is advised of a
potential offering, it e-mails a notice to qualified DLJdirect account holders.
DLJdirect's IPO Center web page provides DLJdirect account holders with
information about the offering and an opportunity to review the preliminary
prospectus on-line. If a qualified DLJdirect account holder decides to purchase
shares in the offering, his or her order can be placed on-line through
DLJdirect.

    Over-Allotment Option. We have granted to the underwriters an option,
exercisable during the 30-day period after the date of this prospectus, to
purchase up to 450,000 additional shares of common stock at the same price per
share as we will receive for the 3,000,000 shares that the underwriters have
agreed to purchase. If the underwriters exercise their over-allotment option to
purchase any of the additional 450,000 shares of common stock, the underwriters
have severally agreed, subject to certain conditions, to purchase approximately
the same percentage thereof as the number of shares to be purchased by each of
them bears to the total number of shares of common stock offered in this
offering. If purchased, the additional shares will be sold by the

                                       58
<PAGE>

underwriters on the same terms as those on which the shares offered in this
offering are being sold. We will be obligated, pursuant to the over-allotment
option, to sell shares to the extent that the over-allotment option is
exercised. The underwriters may exercise the over-allotment option only to
cover over-allotments made in connection with the sale of the shares of common
stock offered in this offering.

    Indemnity. The underwriting agreement contains covenants of indemnity among
the underwriters and us against certain civil liabilities, including
liabilities under the Securities Act of 1933 and liabilities arising from
breaches of representations and warranties contained in the underwriting
agreement.

    Lock-Up Agreements. Each executive officer and director of Princeton eCom
and each holder of more than 1% of our outstanding common stock has agreed,
during the period of 180 days after the effective date of this prospectus,
subject to exceptions, not to offer to sell, contract to sell, or otherwise
sell, dispose of, loan, pledge or grant any rights with respect to any shares
of common stock or any options to purchase any shares of common stock, or any
securities convertible into or exchangeable for shares of common stock owned as
of the date of this prospectus or thereafter acquired directly by such holders
or with respect to which they have the power of disposition, without the prior
written consent of BancBoston Robertson Stephens Inc. However, BancBoston
Robertson Stephens Inc. may, in its sole discretion, and at any time or from
time to time, without notice, release all or any portion of the securities
subject to those lock-up agreements. There are no existing agreements between
the representatives and any of our stockholders who have executed a lock-up
agreement providing consent to the sale of shares prior to the expiration of
the lock-up period.

    Future Sales. In addition, we have agreed that during the lock-up period we
will not, without the prior written consent of BancBoston Robertson Stephens
Inc., subject to certain exceptions,

  . consent to the disposition of any shares held by stockholders subject to
    lock-up agreements prior to the expiration of the lock-up period, or

  . issue, sell, contract to sell, or otherwise dispose of, any shares of
    common stock, any options or warrants to purchase any shares of common
    stock or any securities convertible into, exercisable for or
    exchangeable for shares of common stock other than our sale of shares in
    this offering, the issuance of our common stock upon the exercise of
    outstanding options or warrants, and the issuance of options under
    existing stock option and incentive plans provided that those options do
    not vest prior to the expiration of the lock-up period. See "Shares
    Eligible for Future Sale."

    The underwriters do not intend to confirm sales of more than 5% of the
common stock offered in this offering to accounts over which they exercise
discretionary authority.

    No Prior Public Market. Prior to this offering, there has been no public
market for the common stock. Consequently, the initial public offering price
for the common stock offered by this prospectus has been determined through
negotiations among the company and the representatives. Among the factors
considered in determining the public offering price were:

  . prevailing market conditions;

  . certain of our financial information;

  . the present stage of the company's development;

  . the market valuations of other companies that we and the representatives
    believe to be comparable to us;

  . estimates of our business potential;

  . the present state of our development; and

  . other factors deemed relevant.

    Listing. Our shares of common stock have been approved for quotation on the
Nasdaq National Market under the symbol "ECOM."

    Stabilization. The representatives have advised us that, pursuant to
Regulation M under the Securities Act of 1933, some persons participating in
this offering may engage in transactions, including stabilizing bids,

                                       59
<PAGE>

syndicate covering transactions or the imposition of penalty bids, that may
have the effect of stabilizing or maintaining the market price of the common
stock at a level above that which might otherwise prevail in the open market. A
stabilizing bid is a bid for or the purchase of common stock on behalf of the
underwriters for the purpose of fixing or maintaining the price of the common
stock. A syndicate covering transaction is the bid for or the purchase of
common stock on behalf of the underwriters to reduce a short position incurred
by the underwriters in connection with this offering. A penalty bid is an
arrangement permitting the representatives to reclaim the selling concession
otherwise accruing to an underwriter or syndicate member in connection with
this offering if the common stock originally sold by that underwriter or
syndicate member is purchased by the representatives in a syndicate covering
transaction and has therefore not been effectively placed by such underwriter
or syndicate member. The representatives have advised us that such transactions
may be effected on the Nasdaq National Market or otherwise and, if commenced,
may be discontinued at any time.

    Directed Share Program. The underwriters have reserved up to five percent
(5%) of the common stock to be issued by us and offered for sale in this
offering, at the initial public offering price, to directors, officers,
employees, business associates and the family and friends of the directors,
officers and employees of Princeton eCom. The number of shares of common stock
available to the general public will be reduced to the extent these individuals
purchase reserved shares. Any reserved shares which are not purchased will be
offered by the underwriters to the general public on the same basis as the
other shares offered in this offering.

                                 LEGAL MATTERS

    The validity of the common stock offered hereby will be passed upon for us
by Kelley Drye & Warren LLP, New York, New York. Certain legal matters in
connection with this offering will be passed upon for the underwriters by
Brobeck, Phleger & Harrison LLP, New York, New York.

1997 and 1998 and for the three years in the period ended December 31, 1998

Philadelphia, Pa.,
March 30, 1999

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of Princeton eCom Corporation:

    We have audited the accompanying balance sheets of Princeton eCom
Corporation (a Delaware corporation), formerly Princeton TeleCom Corporation,
as of December 31, 1997 and 1998, and the related statements of operations,
stockholders' equity (deficit) and cash flows for each of the three years in
the period 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 audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Princeton eCom Corporation
as of December 31, 1997 and 1998, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1998,
in conformity with generally accepted accounting principles.

Philadelphia, Pa.,
March 30, 1999, except for
  Note 13, for which the
  date is          .

                         NOTES TO FINANCIAL STATEMENTS

  (Information as of March 31, 1999, and for the three months ended March 31,
                          1998 and 1999, is unaudited)

1. Background:

    On January 25, 1984, Princeton eCom Corporation (the "Company") was
incorporated in the State of Delaware as Princeton TeleCom Corporation. In
March 1999, the Company changed its name to Princeton eCom Corporation. The
Company is a provider of comprehensive electronic bill presentment and payment
services to financial institutions and large businesses which generate a
significant number of recurring bills. The Company's current customers consist
primarily of utilities and financial institutions.

    The Company has incurred significant losses and expects to incur
significant losses on a quarterly and annual basis for the foreseeable future.
As of December 31, 1998, the Company had an accumulated deficit of $10,893,829
and during 1998 the Company incurred a net loss of $3,354,636. Since its
inception, the Company has incurred costs to develop and enhance its
technology, establish marketing and customer relationships and build its
administrative organization. The Company currently intends to substantially
increase its operating expenses to further develop its business. To the extent
that such expenses do not subsequently lead to increased revenues, the
Company's business, results of operations and financial condition will be
materially and adversely affected. In addition, the Company's business model is
unproven and evolving and is subject to possible changing governmental
regulations (see Note 6). Also, the Company may not realize the critical mass
necessary to achieve profitability.

    The accompanying financial statements have been prepared in conformity with
principles of accounting applicable to a going concern. These principles
contemplate the realization of assets and the satisfaction of liabilities in
the normal course of business. Management believes that the Company's existing
cash and cash equivalents will provide sufficient funding for its operating
activities, capital expenditures and other obligations to at least January 1,
2000. Therefore, the accompanying financial statements do not include necessary
adjustments should the Company be unable to continue as a going concern.

2. Significant Accounting Policies:

 Interim Financial Statements

    The financial statements as of March 31, 1999 and for the three months
ended March 31, 1998 and 1999 are unaudited and, in the opinion of management,
include all adjustments (consisting only of normal recurring adjustments)
necessary for a fair presentation of results for those interim periods. The
results of operations for the three months ended March 31, 1998 and 1999 are
not necessarily indicative of the results to be expected for the entire year.

 Use of Estimates

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

 Revenue Recognition

    Service fees are based on contractual rates with customers. Service fee
revenues, which represent transaction fees charged to billers and financial
institutions are recognized as services are performed. Interest income on the
overnight investment of funds received from consumers pending payment
processing is recorded as earned.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

  (Information as of March 31, 1999, and for the three months ended March 31,
                          1998 and 1999, is unaudited)

 Cash and Cash Equivalents

    Cash and cash equivalents include highly liquid investments with original
maturities of three months or less and funds received from consumers pending
payment processing.

 Prepaid Expenses and Other

    In December 1998, the Company mistakenly made certain overpayments to
billers on behalf of consumers. Included in prepaid expenses and other at
December 31, 1998 is $862,906 of such overpayments, which were reimbursed to
the Company in early 1999. At December 31, 1998 and March 31, 1999, prepaid
expenses and other also included certificates of deposit in the aggregate of
$370,000 with original maturities greater than three months and certain related
party amounts (see Note 12).

 Property and Equipment

    Property and equipment are recorded at cost. Property and equipment
capitalized under capital leases are recorded at the present value of the
minimum lease payments due over the term of the lease. Depreciation and
amortization are provided using the straight-line method over the estimated
useful lives or the lease term, whichever is shorter. Expenditures for
maintenance, repairs and betterments that do not prolong the useful life of an
asset have been charged to operations as incurred. Additions and betterments
that substantially extend the useful life of the asset are capitalized. Upon
sale or other disposition of assets, the cost and related accumulated
depreciation and amortization are removed from the respective accounts, and the
resulting gain or loss, if any, is included in operating results.

    The Company reviews its long-lived assets for possible impairment whenever
events or changes in circumstances indicate that the carrying amount of an
asset may not be recoverable. When factors indicate that such assets should be
evaluated for possible impairment, the Company uses an estimate of the related
future undiscounted cash flow in measuring whether the asset should be written
down to fair value. As of March 31, 1999, management believes that there are no
material impairment losses or needed revisions to remaining useful lives.

 Customer Deposits Payable

    Customer deposits payable represents funds received from consumers that are
held by the Company pending payment processing.

 Development Costs

    Research and development costs are charged to expense as incurred. In
conjunction with the development of its services, the Company incurs certain
software development costs. No costs have been capitalized pursuant to
Statement of Financial Accounting Standards ("SFAS") No. 86, "Accounting for
the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed,"
since the development period is relatively short and software development costs
qualifying for capitalization have been relatively insignificant.

 Income Taxes

    Income taxes are accounted for using the liability method. Accordingly,
deferred income tax assets and liabilities are determined based on differences
between the financial statement carrying amounts of assets and liabilities and
their respective income tax basis, measured using enacted tax rates.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

  (Information as of March 31, 1999, and for the three months ended March 31,
                          1998 and 1999, is unaudited)
 Stock Compensation

    The Company has elected to follow Accounting Principles Board ("APB")
Opinion No. 25, "Accounting for Stock Issued to Employees," and related
interpretations in accounting for its employee stock options. Under APB No. 25,
if the exercise price of the Company's employee stock options equals or exceeds
the market price of the underlying stock on the date of the grant, no
compensation expense is recognized. If the exercise price of an option is below
the market price of the underlying stock on the date of grant, compensation
cost is recorded and is recognized in the statements of operations over the
vesting period (see Note 9).

 Earnings Per Share

    The Company follows SFAS No. 128, "Earnings Per Share," which requires a
dual presentation of "basic" and "diluted" earnings per share ("EPS") on the
face of the statements of operations. Basic EPS is computed by dividing net
income (loss) by the weighted average number of shares of common stock
outstanding for the period. Diluted EPS includes the dilutive effect, if any,
from the potential exercise or conversion of securities like stock options,
which would result in the issuance of additional shares of common stock. For
each of the three years in the period ended December 31, 1998 and the three
months ended March 31, 1998 and 1999, the impact of stock options was not
considered as their effect on EPS would be anti-dilutive (see Note 9).

 Fair Value of Financial Instruments

    Cash, accounts receivable, prepaid expenses, customer deposits payable,
accounts payable and accrued expenses are reflected in the accompanying
financial statements at fair value due to the short-term nature of those
instruments. The carrying amount of long-term debt obligations approximate fair
value at the balance sheet dates.

 Recent Accounting Pronouncements

    In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 is effective for fiscal years
beginning after December 31, 1997. SFAS No. 130 establishes standards for the
reporting and display of comprehensive income in a set of financial statements.
Comprehensive income is defined as the change in net assets of a business
enterprise during a period from transactions generated from non-owner sources.
It includes all changes in equity during a period except those resulting from
investments by owners and distributions to owners. The Company has no other
comprehensive income items, therefore, the adoption of SFAS No. 130 had no
impact on the financial statements.

    In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information." SFAS No.
131 applies to all pubic companies and is effective for fiscal years beginning
after December 15, 1997. SFAS No. 131 requires that business segment financial
information be reported in the financial statements utilizing the management
approach. The management approach is defined as the manner in which management
organizes the segments within the enterprise for making operating decisions and
assessing performance. Management believes the Company operates in one business
segment, therefore, the adoption of SFAS No. 131 had no impact on the financial
statements.

    In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position ("SOP") 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use."

                                      F-9

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

  (Information as of March 31, 1999, and for the three months ended March 31,
                          1998 and 1999, is unaudited)

The Company adopted SOP 98-1 in January 1999. The adoption had no material
effect on the Company's financial position or results of operations.

3. Supplemental Cash Flow Information:

    For the years ended December 31, 1996, 1997 and 1998 and the three months
ended March 31, 1998 and 1999, the Company paid interest of $6,467, $15,687,
$14,150, $3,683 and $2,132, respectively. During 1996 and 1997, the Company
financed equipment purchases of $129,624 and $4,445 with capitalized lease
obligations, respectively.

    During the three months ended March 31, 1999, the Company issued options to
purchase common stock to a consultant in exchange for services provided during
the Company's planned initial public offering. The fair value of the options
using the Black-Scholes option pricing model of $138,491 was included in
prepaid expenses and other as of March 31, 1999 in the accompanying balance
sheets.

</TABLE>

 Litigation

    The Company is involved, from time to time, in various legal matters and
claims which are being defended and handled in the ordinary course of business.
None of these matters is expected, in the opinion of management, to have a
material adverse effect upon the financial position or results of operations of
the Company.

 Employment Agreements

    In early 1999, the Company entered into employment agreements with two
officers of the Company. The agreements provide for, among other things,
salaries, bonuses, severance payments and certain other payments payable upon a
change in control, as defined.

 Government Regulation

    Management believes that the Company is not required to be licensed by the
Office of the Comptroller of the Currency, the Federal Reserve Board or other
federal or state agencies that regulate or monitor banks or other providers of
electronic commerce. However, the Company may be periodically audited by
banking authorities since the Company is a supplier of services to financial
institutions. Laws regulating Internet commerce may be enacted to address
issues such as user privacy, pricing, content, taxation and the characteristics
and quality of online products and services, among other things. If enacted,
these laws could have a material adverse effect on the Company's business.

7. Common Stock:

    On September 4, 1998, the Company entered into an agreement with Billing
Concepts Corp. ("BCC") whereby BCC acquired 2,493,870 shares of the Company's
common stock for $10,000,000. BCC was also given the right to purchase the
number of additional shares of the Company's common stock which is equal to the
Company's working capital deficit as of June 30, 1998 in excess of $8.5 million
divided by $4.01. On March 30, 1999, the Company sold BCC 134,376 shares for
$538,848 in full settlement of this provision. In addition, this agreement
provides for, among other things, the right of first refusal on certain equity
transactions.

    Due to the uncertainty surrounding the realization of the net deferred tax
asset, the Company has provided a full valuation allowance. As of December 31,
1998, the Company has net operating loss carryforwards of approximately
$8,600,000 for federal tax purposes, which begin to expire in 2003, and
$7,200,000 for state tax purposes, which begin to expire in 1999. The Tax
Reform Act of 1986 contains provisions that may limit the net operating loss
carryforwards available in any given year in the event of a 50% cumulative
change in ownership over a three-year period.

    All options have terms ranging from five to ten years and generally vest
over four years. The weighted average contractual life of options outstanding
as of March 31, 1999 was four years for options granted at $0.03 per share and
ten years for options granted at $4.00 and $5.33 per share. At March 31, 1999,
there were 2,361,150 shares available for future option grants under the plans.

    In connection with certain options granted to employees during the year
ended December 31, 1998 and the three months ended March 31, 1998 and 1999, the
Company recorded $1,884,500, $159,000 and $1,716,000 of deferred compensation,
respectively. These amounts represent the difference between the fair market
value of the Company's common stock on the date of grant and the exercise price
of options to purchase 733,500, 238,500 and 576,000 shares, respectively, of
the Company's common stock. Deferred compensation is amortized over the vesting
periods of the options, which range from immediate vesting to periods of up to
four years. For the year ended December 31, 1998 and the three months ended
March 31, 1998

$2,352,511 of deferred compensation to be amortized over the remaining vesting
periods, which range from one to four years.

    Pro forma information provided below has been determined as if the Company
had accounted for its employee stock options in accordance with SFAS No. 123,
"Accounting for Stock-Based Compensation." The determination of the fair value
of the options noted above was estimated at the date of grant using a Black-
Scholes option pricing model with the following weighted-average assumptions
for the years ended December 31, 1996, 1997 and 1998: risk free interest rate
of 6.2%, 5.8% and 4.9%, respectively, dividend yield of 0%, volatility factor
of the expected market price of the Company's common stock of 70%, and an
expected life of the options of four years.

Item 14. Indemnification of Directors and Officers

    Section 102 of the Delaware General Corporation Law ("DGCL"), as amended,
allows a corporation to eliminate the personal liability of directors of a
corporation to the corporation or its stockholders for monetary damages for a
breach of fiduciary duty as a director, except where the director breached his
duty of loyalty, failed to act in good faith, engaged in intentional misconduct
or knowingly violated a law, authorized the payment of a dividend or approved a
stock repurchase in violation of Delaware corporate law or obtained an improper
personal benefit.

    Section 145 of the DGCL provides, among other things, that we may 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 (other than an
action by or in our right) by reason of the fact that the person is or was a
director, officer, agent or employee of ours or is or was serving at our
request as a director, officer, agent, or employee of another corporation,
partnership, joint venture, trust or other enterprise, against expenses,
including attorneys' fees, judgment, fines and amounts paid in settlement
actually and reasonably incurred by the person in connection with such action,
suit or proceeding. The power to indemnify applies (a) if such person is
successful on the merits or otherwise in defense of any action, suit or
proceeding, or (b) if such person acted in good faith and in a manner he
reasonably believed to be in our best interest, or not opposed to our best
interest, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The power to indemnify
applies to actions brought by or in our right as well, but only to the extent
of defense expenses (including attorneys' fees but excluding amounts paid in
settlement) actually and reasonably incurred and not to any satisfaction of
judgment or settlement of the claim itself, and with the further limitation
that in such actions no indemnification shall be made in the event of any
adjudication of negligence or misconduct in the performance of his duties to
us, unless the court believes that in light of all the circumstances
indemnification should apply.

    Section 174 of the DGCL provides, among other things, that a director, who
willfully or negligently approves of an unlawful payment of dividends or an
unlawful stock purchase or redemption, may be held liable for such actions. A
director who was either absent when the unlawful actions were approved or
dissented at the time, may avoid liability by causing his or her dissent to
such actions to be entered in the books containing the

                                      II-1
<PAGE>

minutes of the meetings of the board of directors at the time such action
occurred or immediately after such absent director receives notice of the
unlawful acts.

    Our Amended and Restated Certificate of Incorporation will include a
provision that eliminates the personal liability of its directors for monetary
damages for breach of fiduciary duty as a director, except for liability:

  . for any breach of the director's duty of loyalty to Princeton eCom or
    its stockholders;

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

  . under the section 174 of the Delaware General Corporation Law regarding
    unlawful dividends and stock purchases; or

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

    Our Amended and Restated Bylaws provide that:

  . we must indemnify our directors and officers to the fullest extent
    permitted by Delaware law;

  . we may indemnify our other employees and agents to the same extent that
    we indemnified our officers and directors, unless otherwise determined
    by our board of directors; and

  . we must advance expenses, as incurred, to our directors and executive
    officers in connection with a legal proceeding to the fullest extent
    permitted by Delaware law.

    Prior to the completion of this offering, we intend to enter into indemnity
agreements with each of our directors and executive officers to give them
additional contractual assurances regarding the scope of the indemnification
described above and to provide additional procedural protections. In addition,
we intend to obtain directors' and officers' insurance in the amount of $15.0
million providing indemnification for our directors, officers and certain
employees for certain liabilities. We believe that these indemnification
provisions and agreements are necessary to attract and retain qualified
directors and officers.

    The limitation of liability and indemnification provisions in our Amended
and Restated Certificate of Incorporation and Amended and Restated Bylaws may
discourage stockholders from bringing a lawsuit against directors for breach of
their fiduciary duty. They may also have the effect of reducing the likelihood
of derivative litigation against directors and officers, even though such an
action, if successful, might otherwise benefit us and our stockholders.
Furthermore, a stockholder's investment may be adversely affected to the extent
we pay the costs of settlement and damage awards against directors and officers
pursuant to these indemnification provisions.

    At present, there is no pending material litigation or proceeding involving
any of our directors, officers or employees regarding which indemnification is
sought, nor are we aware of any threatened litigation that may result in claims
for indemnification.

Item 15. Recent Sales of Unregistered Securities

    In the last three years, we sold the following securities:

    In June 1996, we amended a stock purchase agreement with C. Richard Corl
dated June 29, 1993. By the terms of this amended stock purchase agreement, an
adjustment was made for the issuance of an additional 9,000 shares of common
stock to Mr. Corl and an adjustment increasing the amount owed to us by Mr.
Corl under a promissory note for an additional $1,350. This sale of securities
was made under the exemption of (S)4(2) under the Securities Act of 1933.

    In July 1996, we sold an aggregate of 120,000 shares of common stock, of
which 30,000 shares were sold to each of Lawrence Greenberg, Diane Hancharik,
Susan Hubbard-Walker, and Alex Peterhans at a purchase price of $1,000. The
consideration for each of these purchases was a promissory note with a
principal

                                      II-2
<PAGE>

amount of $1,000 and 6% interest per annum. Each of these promissory notes was
satisfied in March 1999. In addition, in July 1996 we delivered 45,000 shares
to Benson Lapides in satisfaction of amounts which we owed Mr. Lapides for
consulting services which he performed for us. These sales of securities were
made under the exemption of (S)4(2) under the Securities Act of 1933.

    In March 1997, we sold an additional 30,000 shares of common stock to Mr.
Peterhans for an aggregate purchase price of $1,000. The consideration for this
purchase was a promissory note with a principal amount of $1,000 and an
interest rate of 6% per annum.

    In December 1997, we sold 60,000 additional shares of common stock, of
which an additional 30,000 shares were sold to Mr. Greenberg and 30,000 shares
were sold to Mrs. Hubbard-Walker, in each instance for an aggregate purchase
price of $1,000. The consideration for each of these purchases was a promissory
note with a principal amount of $1,000 and 6% per annum. Each of these
promissory notes was satisfied in March 1999. These sales of securities were
made under the exemption of (S)4(2) under the Securities Act of 1933.

    On September 4, 1998, the Company sold 2,493,870 shares of common stock to
Billing Concepts Corp. for an aggregate purchase price of $10,000,000 in cash.
This sale of securities was made under the exemption of (S)4(2) and Rule 506 of
Regulation D under the Securities Act of 1933.

    On March 30, 1999, the Company sold an additional 134,376 shares of common
stock to Billing Concepts Corp. for an aggregate purchase price of $538,848.
These shares were sold to Billing Concepts Corp. under the terms of an option
granted to Billing Concepts Corp. in connection with their September 1998
purchase, which option permitted the purchase of additional shares if the
Company's working capital deficit, as of June 30, 1998, exceeded $8.5 million.
These shares were sold to Billing Concepts Corp. under the exemptions of
(S)4(2) and Rule 506 of Regulation D under the Securities Act of 1933.

Item 17. Undertakings

    The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant 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 registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

    The undersigned registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this registration statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.

      (2) For the purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at
  that time shall be deemed to be the initial bona fide offering thereof.

signed on its behalf by the undersigned, thereunto duly authorized, in the City
of New York, State of New York, on the 2nd day of June, 1999.

of the foregoing, the resolutions providing for issuance of any series of
Preferred Stock may provide that such series shall be superior or rank equally
or be junior to the Preferred Stock of any other series to the extent permitted
by law. Except as otherwise provided in this Certificate of Incorporation, no
vote of the holders of the Preferred Stock or Common Stock shall be a
prerequisite to the designation or issuance of any shares of any series of the
Preferred Stock authorized by and complying with the conditions of this
Certificate of Incorporation, the right to have such vote being expressly waived
by all present and future holders of the capital stock of the Corporation.

     FIFTH.  The Corporation shall have a perpetual existence.

     SEVENTH.  Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed

the stockholders or class of stockholders of this Corporation, as the case may
be, to be summoned in such manner as the said court directs.  If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
and also on this Corporation.

     EIGHTH.  Except to the extent that the General Corporation Law of Delaware
prohibits the elimination or limitation of liability of directors for breaches
of fiduciary duty, no director of the Corporation shall be personally liable to
the Corporation or its stockholders for monetary damages for any breach of
fiduciary duty as a director, notwithstanding any provision of law imposing such
liability.  No amendment to or repeal of this provision shall apply to or have
any effect on the liability or alleged liability of any director of the
Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.

indemnified by the Corporation to the fullest extent permitted by the General
Corporation Law of Delaware against all expenses and liabilities, including
counsel fees, reasonably incurred by or imposed upon that person in connection
with any proceeding to which the person may be made, or threatened to be made, a
party, or in which that person may become involved by reason of his being or

          PRINCETON TELECOM CORPORATION
          395 Wall Street, Princeton, New Jersey 08540

                                          hereinafter referred to as the Tenant,
WITNESSETH: That the Landlord hereby demises and leases unto the Tenant, and the
Tenant hereby hires and takes from the Landlord for the term and upon the
rentals hereinafter specified, the premises described as follows, situated in
the Township of Montgomery County of Somerset and State of New Jersey.

General office space consisting of 4,475 square feet, using exterior dimensions,
and being located in Building 151-175 Wall Street, Research Park and being more
particularly described as 165 Wall Street.

     SEE ADDENDUM "B" FOR LOCATION OUTLINED IN RED.

  The term of this demise shall be for Three (3) Years beginning June 1, 1994
and ending May 31, 1997.

  The rent for the demised term shall be -- ONE HUNDRED SIXTY-ONE THOUSAND ONE
HUNDRED DOLLARS ____________________ (161,100.00), which shall accrue at the
yearly rate of

                   $53,700.00 per year for years 1 through 3.

  The said rent is to be payable monthly in advance on the first day of each
calendar month for the term hereof, in instalments as follows:

              $4,475.00 per month per year for years 1 through 3

at the office of Research Park, 194 Nassau Street, Princeton, NJ 08542 or as may
be otherwise directed by the Landlord in writing.

              THE ABOVE LETTING IS UPON THE FOLLOWING CONDITIONS:

  First. -- The Landlord covenants that the Tenant, on paying the said rental
and performing the covenants and conditions in this Lease contained, shall and
may peaceably and quietly have, hold and enjoy the demised premises for the term
aforesaid.

  Second. -- The Tenant covenants and agrees to use the demised premises as a
general office use only,


and agrees not to use or permit the premises to be used for any other purpose
without the prior written consent of the Landlord endorsed hereon.

  Third. -- The Tenant shall, without any previous demand therefor, pay to the
Landlord, or its agent, the said rent at the times and in the manner above
provided.  In the event of the non-payment of said rent, or any instalment
thereof, at the times and in the manner above provided, and if the same shall
remain in default for ten days after becoming due, or if the Tenant shall be
dispossessed for non-payment of rent, or if the leased premises shall be
deserted or vacated, the Landlord or its agents shall have the right to and may
enter the said premises as the agent of the Tenant, either by force or
otherwise, without being liable for any prosecution or damages therefor, and may
relet the premises as the agent of the Tenant, and receive the rent therefor,
upon such terms as shall be satisfactory to the Landlord, and all rights of the
Tenant to repossess the premises under this lease shall be forfeited.  Such re-
entry by the Landlord shall not operate to release the Tenant from any rent to
be paid or covenants to be performed hereunder during the full term of this
lease.  For the purpose of reletting, the Landlord shall be authorized to make
such repairs or alterations in or to the leased premises as may be necessary to
place the same in good order and condition.  The Tenant shall be liable to the
Landlord for the cost of such repairs or alterations, and all expenses of such
reletting.  If the sum realized or to be realized from the reletting is
insufficient to satisfy the monthly or term rent provided in this lease, the
Landlord, at its option, may require the Tenant to pay such deficiency month by
month, or may hold the Tenant in advance for the entire deficiency to be
realized during the term of the reletting.  The Tenant shall not be entitled to
any surplus accruing as a result of the reletting.  The Landlord is hereby
granted a lien, in addition to any statutory lien or right to distrain that may
exist, on all personal property of the Tenant in or upon the demised premises,
to secure payment of the rent and performance of the covenants and conditions of
this lease.  The Landlord shall have the right, as agent of the Tenant, to take
possession of any furniture, fixtures or other personal property of the Tenant
found in or about the premises, and sell the same at public or private sale and
to apply the proceeds thereof to the payment of any monies becoming due under
this lease, the Tenant hereby waiving the benefit of all laws exempting property
from execution, levy and sale on distress or judgment.  The Tenant agrees to
pay, as additional rent, all attorney's fees and other expenses incurred by the
Landlord in enforcing any of the obligations under this lease.

  Fourth. -- The Tenant shall not sub-let the demised premises nor any portion
thereof, nor shall this lease be assigned by the Tenant without the prior
written consent of the Landlord endorsed hereon, which consent shall not be
unreasonably withheld.

  Fifth. -- The Tenant has examined the demised premises, and accepts them in
their present condition (except as otherwise expressly provided herein) and
without any representations on the part of the Landlord or its agents as to the
present or future condition of the said premises.  The Tenant shall keep the
demised premises in good condition, and shall redecorate, paint and renovate the
said premises as may be necessary to keep them in repair and good appearance.
The Tenant shall quit and surrender the premises at the end of the demised term
in as good condition as the reasonable use thereof will permit.  The Tenant
shall not make any alterations, additions, or improvements to said premises
without the
<PAGE>

prior written consent of the Landlord. All erections, alterations, additions and
improvements, whether temporary or permanent in character, which may be made
upon the premises either by the Landlord or the Tenant, except furniture or
movable trade fixtures installed at the expense of the Tenant, shall be the
property of the Landlord and shall remain upon and be surrendered with the
premises as a part thereof at the termination of this Lease, without
compensation to the Tenant. The Tenant further agrees to keep said premises and
all parts thereof in a clean and sanitary condition and free from trash,
inflammable material and other objectionable matter. If this lease covers
premises, all or a part of which are on the ground floor, the Tenant further
agrees to keep the sidewalks in front of such ground floor portion of the
demised premises clean and free of obstructions, snow and ice.

  Sixth. - In the event that any mechanics' lien is filed against the premises
as a result of alterations, additions or improvements made by the Tenant, the
Landlord, at its option, after thirty days' notice to the Tenant, may terminate
this lease and may pay the said lien, without inquiring into the validity
thereof, and the Tenant shall forthwith reimburse the Landlord the total expense
incurred by the Landlord in discharging the said lien, as additional rent
hereunder.

  Seventh. - The Tenant agrees to replace at the Tenant's expense any and all
glass which may become broken in and on the demised premises.  Plate glass and
mirrors, if any, shall be insured by the Tenant at their full insurable value in
a company satisfactory to the Landlord.  Said policy shall be of the full
premium type, and shall be deposited with the Landlord or its agent.

  Eighth. - The Landlord shall not be responsible for the loss of or damage to
property, or injury to persons, occurring in or about the demised premises, by
reason of any existing or future condition, defect, matter or thing in said
demised premises or the property of which the premises are a part, or for the
acts, omissions or negligence of other persons or tenants in and about the said
property.  The Tenant agrees to indemnify and save the Landlord harmless from
all claims and liability for losses of or damage to property, or injuries to
persons occurring in or about the demised premises.

  Ninth. - *Utilities and services furnished to the demised premises for the
benefit of the Tenant shall be provided and paid for as follows:  water and
sewer by the Landlord; gas by the Landlord; electricity by the Landlord; heat by
the Landlord; refrigeration by the N/A; hot water by the Landlord.  Equipment
maintenance, replacement of equipment and yearly service of equipment which
supplies heat, air and electric to the demised premises covered by this lease
are to be paid for by the Landlord.  *See Paragraph 39th.

The Landlord shall not be liable for any interruption or delay in any of the
above services for any reason.  See Paragraph 41st.

  Tenth. - The Landlord, or its agents, shall have the right to enter the
demised premises at reasonable hours in the day or night to examine the same, or
to run telephone or other wires, or to make such repairs, additions or
alterations as it shall deem necessary for the safety, preservation or
restoration of the improvements, or for the safety or convenience of the
occupants or users thereof (there being no obligation, however, on the part of
the Landlord to make any such repairs, additions or alterations), or to exhibit
the same to prospective purchasers and put upon the premises a suitable "For
Sale" sign.  For three months prior to the expiration of the demised term, the
Landlord, or its agents, may similarly exhibit the premises to prospective
tenants, and may place the usual "To Let" signs thereon.

  Eleventh. - In the event of the destruction of the demised premises or the
building containing the said premises by fire, explosion, the elements or
otherwise during the term hereby created, or previous thereto, or such partial
destruction thereof as to render the premises wholly untenantable or unfit for
occupancy, or should the demised premises be so badly injured that the same
cannot be required within ninety days from the happening of such injury, then
and in such case the term hereby created shall, at the option of Landlord, cease
and become null and void from the date of such damage or destruction, and the
Tenant shall immediately surrender said premises and all the Tenant's interest
therein to the Landlord, and shall pay rent only to the time of such surrender,
in which event the Landlord may re-enter and re-possess the premises thus
discharged from this lease and may remove all parties therefrom. Should the
demised premises be rendered untenantable and unfit for occupancy, but yet be
repairable within ninety days from the happening of said injury, the Landlord
may enter and repair the same with reasonable speed, and the rent shall not
accrue after said injury or while repairs are being made, but shall recommence
immediately after said repairs shall be completed. But if the premises shall be
so slightly injured as not to be rendered untenantable and unfit for occupancy,
then the Landlord agrees to repair the same with reasonable promptness and in
that case the rent accrued and accruing shall not cease or determine. The Tenant
shall immediately notify the Landlord in case of fire or other damage to the
premises.

  Twelfth. - The Tenant agrees to observe and comply with all laws, ordinances,
rules and regulations of the Federal, State, County and Municipal authorities
applicable to the business to be conducted by the Tenant in the demised
premises.  The Tenant agrees not to do or permit anything to be done in said
premises, or keep anything therein, which will increase the rate of fire
insurance premiums on the improvements or any part thereof, or on property kept
therein, or which will obstruct or interfere with the rights of other tenants,
or conflict with the regulations of the Fire Department or with any insurance
policy upon said improvements or any part thereof.  In the event of any increase
in insurance premiums resulting from the Tenant's occupancy of the premises, or
from any act or omission on the part of the Tenant, the Tenant agrees to pay
said increase in insurance premiums on the improvements or contents thereof as
additional rent.

  Thirteenth. - No sign, advertisement or notice shall be affixed to or placed
upon any part of the demised premises by the tenant, except in such manner, and
of such size, design and color as shall be approved in advance in writing by the
Landlord.

See Paragraph 42nd

  Fourteenth. - This lease is subject and is hereby subordinated to all present
and future mortgages, deeds of trust and other encumbrances affecting the
demised premises or the property of which said premises are a part.  The Tenant
agrees to execute, at no expense to the Landlord any instrument which may be
deemed necessary or desirable by the Landlord, to further effect the
subordination of this lease to any such mortgage, deed of trust or encumbrance.
See Paragraph 53rd.

  Fifteenth. - In the event of the sale by the Landlord of the demised
premises, or the property of which said premises are a part, the Landlord or the
purchaser may terminate this lease on the thirtieth day of April in any year
upon giving the Tenant notice of such termination prior to the first day of
January in the same year.

  Sixteenth. - The rules and regulations regarding the demised premises, affixed
to this lease, if any, as well as any other and further reasonable rules and
regulations which shall be made by the Landlord, shall be observed by the Tenant
and by the Tenant's employees, agents and customers.  The Landlord reserves the
right to rescind any presently existing rules applicable to the demised
premises, and to make such other and further reasonable rules and regulations
as, in its judgment, may from time to time be desirable for the safety, care and
cleanliness of the premises, and for the preservation of good order therein,
which rules, when so made and notice thereof given to the Tenant, shall have the
same force and effect as if originally made a part of this lease.  Such other
and further rules shall not, however, be inconsistent with the proper and
rightful enjoyment by the Tenant of the demised premises.

  Seventeenth. - In case of violation by the Tenant of any of the covenants,
agreements and conditions of this lease, or of the rules and regulations now or
hereafter to be reasonably established by the Landlord, and upon failure to
discontinue such violation within ten days after notice thereof given to the
Tenant, this lease shall thenceforth, at the option of the Landlord, become null
and void, and the Landlord may re-enter without further notice or demand. The
rent in such case shall become due, be apportioned and paid on and up to the day
of such re-entry, and the Tenant shall be liable for all loss or damage
resulting from such violation as aforesaid. No waiver by the Landlord of any
violation or breach of condition by the Tenant shall constitute or be construed
as a waiver of any other violation or breach of condition, nor shall lapse of
time after breach of condition by the Tenant before the Landlord shall exercise
its option under this paragraph operate to defeat the right of the Landlord to
declare this lease null and void and to re-enter upon the demised premises after
the said breach or violation.
<PAGE>

  Eighteenth. -- All notices and demands, legal or otherwise, incidental to this
lease, or the occupation of the demised premises, shall be in writing.  If the
Landlord or its agent desires to give or serve upon the Tenant any notice or
demand, it shall be sufficient to send a copy thereof by registered mail,
addressed to the Tenant at the demised premises, or to leave a copy thereof with
a person of suitable age found on the premises, or to post a copy thereof upon
the door to said premises.  Notices for the Tenant to the Landlord shall be sent
by registered mail or delivered to the Landlord at the place hereinbefore
designated for the payment of rent, or to such party or place as the Landlord
may form time to time designate in writing.

  Nineteenth. -- It is further agreed that if at any time during the term of
this lease the Tenant shall make any assignment for the benefit of creditors, or
be decreed insolvent or bankrupt according to law, or if a receiver shall be
appointed for the Tenant, then the Landlord may, at its option, terminate this
lease, exercise of such option to be evidenced by notice to that effect served
upon the assignee, receiver, trustee or other person in charge of the
liquidation of the property of the Tenant or the Tenant's estate, but such
termination shall not release or discharge any payment of rent payable hereunder
and then accrued, or any liability then accrued by reason of any agreement or
covenant herein contained on the part of the Tenant, or the Tenant's legal
representatives.

  Twentieth. -- In the event that the Tenant shall remain in the demised
premises after the expiration of the term of this lease without having executed
a new written lease with the Landlord, such holding over shall not constitute a
renewal or extension of this lease. The Landlord may, at its option, elect to
treat the Tenant as one who has not removed at the end of his term, and
thereupon be entitled to all the remedies against the Tenant provided by law in
that situation, or the Landlord may elect, at its option, to construe such
holding over as a tenancy from month to month, subject to all the terms and
conditions of this lease, except as to duration thereof, and in that event the
Tenant shall pay monthly rent in advance at the rate provided herein as
effective during the last month of the demised term.

  Twenty-first. -- If the property or any part thereof wherein the demised
premises are located shall be taken by public or quasi-public authority under
any power of eminent domain or condemnation, this lease, at the option of the
Landlord, shall forthwith terminate and the Tenant shall have no claim or
interest in or to any award of damages for such taking.

  Twenty-second. -- The Tenant has this day deposited with the Landlord the sum
of $8,950.00 as security for the full and faithful performance by the Tenant of
all the terms, covenants and conditions of this lease upon the Tenant's part to
be performed, which said sum shall be returned to the Tenant after the time
fixed as the expiration of the term herein, provided the Tenant has fully and
faithfully carried out all of said terms, covenants and conditions on Tenant's
part to be performed.  In the event of a bona fide sale, subject to this lease,
the Landlord shall have the right to transfer the security to the vendee for the
benefit of the Tenant and the landlord shall be considered released by the
Tenant from all liability for the return of such security; and the Tenant agrees
to look to the new Landlord solely for the return of the said security, and it
is agreed that this shall apply to every transfer or assignment made of the
security to a new Landlord.  The security deposited under this lease shall not
be mortgaged, assigned or encumbered by the Tenant without the written consent
of the Landlord.

  Twenty-third. -- Any dispute arising under this lease shall be settled by
arbitration.  Then Landlord and tenant shall each choose an arbitrator, and the
two arbitrators thus chosen shall select a third arbitrator.  The findings and
award of the three arbitrators thus chosen shall be final and binding on the
parties hereto.

  Twenty-fourth. -- No rights are to be conferred upon the Tenant until this
lease has been signed by the Landlord, and an executed copy of the lease has
been delivered to the Tenant.

  Twenty-fifth. -- The foregoing rights and remedies are not intended to be
exclusive but as additional to all rights and remedies the Landlord would
otherwise have by law.

  Twenty-sixth. -- All of the terms, covenants and conditions of this lease
shall inure to the benefit of and be binding upon the respective heirs,
executors, administrators, successors and assigns of the parties hereto.
However, in the event of the death of the Tenant, if an individual, the Landlord
may, at its option, terminate this lease by notifying the executor or
administrator of the Tenant at the demised premises.

  Twenty-seventh. -- This lease and the obligation of Tenant to pay rent
hereunder and perform all of the other covenants and agreements hereunder on
part of Tenant to be performed shall in nowise be affected, impaired or excused
because Landlord is unable to supply or is delayed in supplying any service
expressly or impliedly to be supplied or is unable to make, or is delayed in
making any repairs, additions, alterations or decorations or is unable to supply
or is delayed in supplying any equipment or fixtures if Landlord is prevented or
delayed from so doing by reason of governmental preemption in connection with
the National Emergency declared by the President of the United States or in
connection with any rule, order or regulation of any department or subdivision
thereof of any governmental agency or by reason of the conditions of supply and
demand which have been or are affected by the war.

  Twenty-eighth. -- This instrument may not be changed orally.

  Twenty-ninth. -- See Addendum "A" attached hereto and made a part hereof.

  Thirtieth. -- See Addendum "A" attached hereto and made a part hereof.

  Thirty-first. -- Intentionally left blank.
