THIS SUMMARY DOES NOT CONTAIN ALL OF THE INFORMATION YOU SHOULD CONSIDER BEFORE
INVESTING IN THE COMMON STOCK. YOU SHOULD READ THE ENTIRE PROSPECTUS CAREFULLY.
UNLESS STATED OTHERWISE, ALL SHARE DATA IN THIS PROSPECTUS REFLECTS OUR 3 FOR 1
STOCK SPLIT IN THE FORM OF A STOCK DIVIDEND, WHICH HAS A RECORD DATE OF APRIL
23, 1999 AND A DISTRIBUTION DATE OF MAY 14, 1999. REFERENCES TO "WE," "US,"
"OUR" AND "NET.B@NK" GENERALLY REFER TO NET.B@NK, INC. AND ITS SOLE SUBSIDIARY,
NET.B@NK, ON A CONSOLIDATED BASIS, EXCEPT WHERE WE INDICATE THAT NET.B@NK, INC.
MEANS ONLY THE PARENT ENTITY AND NET.B@NK REFERS ONLY TO THE BANKING SUBSIDIARY.
 
OUR BUSINESS
 
    Net.B@nk, our sole subsidiary, is the largest federally-insured bank
operating exclusively on the internet. Our mission is to profitably provide a
broad range of banking and financial services to the growing number of internet
users. Our low cost branchless business model allowed us to attain profitability
within a year of acquiring our bank charter and to continue to maintain
profitability while passing along our operating cost savings to customers in the
form of attractive interest rates and low fees.
 
    Our unique, internet-based operating strategy has allowed us to experience
rapid growth. During 1998, our customer accounts grew from 4,755 to 17,408,
deposits grew from $58.7 million to $283.6 million and total assets grew from
$93.2 million to $388.4 million. During 1998, we added an average of 1,054 net
customer accounts per month. At March 31, 1999, we had 24,634 customer accounts,
$332.7 million in deposits and $526.5 million in total assets. During the four
months ended April 30, 1999, we added an average of over 2,900 net customer
accounts per month with 4,865 added in April alone.
 
    We offer a broad array of products and services that customers would
typically expect from a traditional bank. Our products and services include
checking and money market accounts, certificates of deposit, electronic bill
payment, debit cards, credit cards, mortgage loans, business equipment leases
and securities brokerage services. We plan to offer consumer loans, including
home equity and automobile loans, beginning in the third quarter of 1999. We
also intend to develop additional products and services such as insurance
products, electronic bill presentment and electronic document and image storage
in a virtual safe deposit box.
 
    Since our equity offering in February 1999, we have continued to experience
rapid growth in our business and have entered into several new programs to
expand and improve our operational and product capabilities. Since February
1999, we have initiated the following:
 
    - EXPANDED MARKETING PROGRAM. We embarked on a new marketing program that
      has been highly successful in reaching our targeted audience and has
      produced a significant increase in checking accounts. We believe this
      growth in our checking account base indicates growing customer willingness
      to move their everyday banking activities to Net.B@nk and will result in
      long-term customer relationships. Furthermore, we believe that our
      checking account customers will visit our Web site more frequently and
      spend more time on our Web site, allowing us to cross-sell a variety of
      other products and services.
 
    - SERVICING AGREEMENT WITH PNC BANK CORP. We entered into a consumer loan
      processing and servicing agreement with PNC Bank Corp. This agreement will
      allow us to offer consumer loan products on-line. PNC will provide
      origination and loan servicing for these consumer loans as well as
      substantially all consumer loans for which we retain servicing rights on a
      scalable basis at a favorable cost.
 
    - IMPROVED CUSTOMER SERVICE. We increased our customer support staff by over
      70% in order to maintain high-quality customer service. We have also
      invested in advanced technology and
 
                                       3
<PAGE>
      implemented new procedures in order to continually improve the quality and
      responsiveness of our customer service.
 
    - STRENGTHENED LENDING AND FINANCIAL OPERATIONS. We expanded our mortgage
      lending capabilities through a mortgage loan origination partnership with
      Virtuallender.com. We strengthened our lending and financial operations by
      adding several experienced individuals to our professional staff.
      Additionally, we have significantly increased our loan portfolio while
      continuing to maintain a conservative lending and investment strategy.
 
OUR MARKET OPPORTUNITY
 
    By offering a broad array of financial services via the internet, we are
well-positioned to capitalize on the internet's rapid growth. According to
International Data Corporation, the number of worldwide internet users is
projected to grow from an estimated 159.3 million in 1998 to an estimated 410.4
million by 2002. The internet is emerging rapidly as a means of providing
financial services. According to Jupiter Communications, the number of on-line
banking households in the United States is projected to grow from an estimated
6.6 million in 1998 to an estimated 17.1 million in 2002. A demographic study by
Jupiter Communications indicates that internet users tend to be young, mobile
professionals with relatively high incomes. We believe these demographics
suggest a growing market for the convenience, attractive interest rates and low
fees that characterize Net.B@nk.
 
    As the first federally-insured bank to operate solely on the internet, we
have a first mover advantage relative to on-line banks with less extensive
market presence and less established operating histories. In addition, we have a
competitive cost advantage over traditional banks.
 
OUR STRATEGY
 
    Our objective is to become the leading provider of a full range of on-line
financial services. To accomplish this objective, we intend to:
 
    - Build national brand awareness through increased marketing efforts.
 
    - Expand our customer base by offering attractive interest rates and low
      fees, a result of our low-cost, branchless business model.
 
    - Develop new products and services and enter into strategic alliances where
      appropriate.
 
    - Employ a conservative lending and investment strategy to maintain high
      asset quality.
 
    - Outsource operational functions to provide scalability and flexibility.
 
    - Generate noninterest income through cross-marketing initiatives.

(1) On April 13, 1999, we declared a 3 for 1 split of our common stock to be
    effected in the form of a stock dividend payable on May 14, 1999 to
    shareholders of record as of the close of business on April 23, 1999. All
    references to share and per share amounts have been retroactively adjusted
    to reflect this split.
 
(2) Assuming no income tax benefit and a statutory income tax rate of 34% for
    the year, pro forma net income per common and potential common share for the
    year ended December 31, 1998 would have been $0.03 per share, basic, and
    $0.02 per share, diluted.

                                  RISK FACTORS
 
    AN INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CAREFULLY CONSIDER THE SPECIFIC FACTORS LISTED BELOW, TOGETHER WITH THE
CAUTIONARY STATEMENT THAT FOLLOWS THIS SECTION AND THE OTHER INFORMATION
INCLUDED IN THIS PROSPECTUS BEFORE PURCHASING OUR COMMON STOCK.
 
    THE SHARES OF OUR COMMON STOCK ARE NOT SAVINGS ACCOUNTS, DEPOSITS OR OTHER
OBLIGATIONS OF A BANK OR SAVINGS ASSOCIATION AND ARE NOT INSURED BY THE FDIC OR
ANY OTHER GOVERNMENTAL AGENCY.
 
WE COULD SUSTAIN LOSSES IF THE QUALITY OF OUR LOAN PORTFOLIO DETERIORATES
 
    If the quality of our loan portfolio deteriorates due to economic downturns
or our inaccurate assessment of borrower creditworthiness, our interest income
and net interest margin could decrease and our loan loss provision could
increase. This could result in losses that materially adversely affect our
business, financial condition, results of operations and cash flows. A
significant portion of our net income is derived from our loan portfolio. If an
economic downturn occurs either generally or in the Western or Southeastern
United States, the regions collectively representing the greatest concentration
of loans in our loan portfolio, borrowers may be less likely to repay their
loans as scheduled.
 
OUR SUCCESS DEPENDS ON THE CONTINUED GROWTH IN USE AND COMMERCIAL VIABILITY OF
  THE INTERNET
 
    Our future success depends substantially on continued growth in use of the
internet. The internet is, however, a relatively new commercial marketplace and
may not continue to grow. If internet use does not continue to grow, our
business, financial condition, results of operations and cash flows could be
materially adversely affected.
 
    Additionally, to the extent the internet's technical infrastructure or
security concerns adversely affect its growth, our business, financial
condition, results of operations and cash flows could be materially adversely
affected. If the number of internet users and the level of use continues to
grow, the internet's technical infrastructure may become unable to support the
demands placed upon it. Furthermore, third-party vendors might not be able to
timely and adequately develop the necessary technical infrastructure for
significant increases in electronic commerce, such as a reliable network
backbone, or to introduce performance improvements, such as high-speed modems.
The internet could also lose its commercial viability due to delays in the
development or adoption of new standards and protocols required to handle
increased levels of activity or due to increased governmental regulation.
Changes in or insufficient availability of telecommunication services could
produce slower response times and adversely affect use of the internet.
Furthermore, the general public's security concerns regarding the transmittal of
confidential information, such as credit card numbers, over the internet might
persist or even worsen. These security concerns could lead to resistance against
widespread acceptance of the internet as a viable commercial marketplace.
 
OUR OPERATIONS COULD BE INTERRUPTED IF OUR NETWORK OR COMPUTER SYSTEMS FAIL OR
  EXPERIENCE A SECURITY BREACH
 
    Interruptions in our operations resulting from damage or failure of our
network or computer system could materially adversely affect our business,
financial condition, results of operations and cash flows. Because we conduct
our business over the internet and outsource several critical functions to third
parties, our operations depend on our ability, as well as that of our
third-party service providers, to protect our computer systems and network
infrastructure against damage from fire, power loss, telecommunications failure,
physical break-ins or similar catastrophic events. Our computer systems and
network infrastructure could be vulnerable to unforeseen problems.
 
    In addition, any compromise or breach of our network or computer system
security could have a material adverse effect on our business, financial
condition, results of operations and cash flows. A
 
                                       7
<PAGE>
significant barrier to on-line financial transactions is the secure transmission
of confidential information over public networks. We rely on encryption and
authentication technology to provide the security and authentication necessary
for secure transmission of confidential information. Advances in computer
capabilities, new discoveries in the field of cryptography or other developments
could result in a compromise or breach of the algorithms Net.B@nk and its
third-party service providers use to protect customer transaction data. See
"Business--Security."
 
    We are part of a rapidly evolving electronic commerce market. Market
acceptance of internet banking depends substantially on widespread adoption of
the internet for general commercial and financial services transactions. If
another provider of commercial services through the internet were to suffer
damage from a physical break-in, security breach or other disruptive problem
caused by the internet or other users, the growth and public acceptance of the
internet for commercial transactions could suffer. Such an event could deter
potential customers or cause customers to leave us and thereby materially
adversely affect our business, financial condition, results of operations and
cash flows.
 
INDUSTRY COMPETITION MAY ADVERSELY AFFECT OUR SUCCESS
 
    The banking industry is highly competitive in general, and the market for
internet banking in particular has experienced a recent surge in new entrants.
Our future profitability depends on our ability to compete successfully. We
believe our ability to compete successfully depends on a number of factors,
including:
 
    - Market presence;
 
    - Customer service and satisfaction;
 
    - The capacity, reliability and security of our network infrastructure;
 
    - Ease of access to and navigation of the internet;
 
    - Our competitors' interest rates and service fees;
 
    - The scope of our products and services and the rate at which we and our
      competitors introduce them; and
 
    - Industry and general economic trends.
 
    If we experience difficulty in any of these areas, our business, financial
condition, results of operations and cash flows could be materially adversely
affected.
 
    In addition, many of our principal competitors, traditional banks and
thrifts, other internet banks and other financial service providers, such as
brokerage and insurance companies, have greater financial and other resources
than we do. Because there are few barriers to on-line market entry for existing
chartered financial institutions, our competitors could implement internet
banking operations with relative ease. Furthermore, brokerage companies and
other financial service providers may not be subject to the same degree of
regulation as we are. See "Business--Competition."
 
FAILURE TO IMPLEMENT OUR BUSINESS STRATEGY OR MANAGE OUR GROWTH EFFECTIVELY MAY
  ADVERSELY AFFECT OUR FINANCIAL PERFORMANCE
 
    We may not succeed in implementing our business strategy and, even if we do
succeed, our strategy may not have the favorable impact on operations that we
anticipate. Our success depends on our ability to execute our marketing plan,
leverage our low cost structure, offer a broad array of products and services,
provide convenient, high-quality customer service and employ other elements of
our business strategy. We may not be able to manage effectively the expansion of
our operations or achieve the rapid execution necessary to exploit fully the
market for our services. If we are unable to manage growth effectively, or to
otherwise adequately implement our business strategy, our business,
 
                                       8
<PAGE>
financial condition, results of operations and cash flows could be materially
adversely affected. See "Business--Growth Strategy."
 
FAILURE TO INTRODUCE NEW PRODUCTS AND SERVICES SUCCESSFULLY MAY CAUSE US TO LOSE
  MARKET SHARE
 
    If we are unable to develop and bring additional products and services to
market in a timely manner, we could lose market share to competitors who are
able to offer these additional products and services, which could materially
adversely affect our business, financial condition, results of operations and
cash flows. Our success depends in part upon our ability to offer new products
and services that meet changing customer requirements. See "Business--Industry
Background," "--The Net.B@nk Solution" and "--Products and Services."
 
OUR PROFITABILITY AND GROWTH MAY BE ADVERSELY AFFECTED IF INTERNET BANKING DOES
  NOT BECOME WIDELY ACCEPTED
 
    If the internet banking market does not continue to develop, our business,
financial condition, results of operations and cash flows could be materially
adversely affected. The market for internet banking services is rapidly evolving
and the ultimate demand for and market acceptance of internet banking remains
uncertain. Market acceptance of internet banking depends on consumer willingness
to use the internet for general commercial and financial services transactions.
Other critical issues concerning the commercial use of the internet, including
reliability, cost, ease of use and access and quality of service, may also
impact the growth of internet use. Consequently, internet banking may not become
as widely accepted as traditional methods of banking and our profitability and
growth could be adversely affected. See "Business--Industry Background" and
"--The Net.B@nk Solution."
 
OUR COMPETITIVE POSITION DEPENDS ON OUR ABILITY TO ATTRACT AND RETAIN KEY
  PERSONNEL
 
    Our success depends upon the continued service of our senior management team
and key technical personnel and upon our ability to attract and retain qualified
personnel. If we lose the services of our key personnel, or are unable to
attract additional qualified personnel, our business, financial condition,
results of operations and cash flows could be materially adversely affected. On
April 30, 1999, Donald S. Shapleigh, Jr. resigned as our President. We have not
yet hired anyone to replace him and cannot predict when this position will be
filled. To date, this vacancy has not adversely affected our operations;
however, we cannot predict the effect a continued vacancy in this position will
have on our operations. Our employees do not have employment agreements and may
voluntarily terminate their employment at any time. In the current market,
competition for qualified employees, particularly in technical fields, is
intense. In our experience, it can take a significant period of time to identify
and hire personnel with the combination of skills and attributes required to
carry out our strategy. We do not carry key person life insurance on any of our
executives. See "Management."
 
CHANGES IN INTEREST RATES MAY DECREASE OUR NET INTEREST INCOME
 
    An increase or decrease in interest rates could have a material adverse
effect on our net interest income, capital and liquidity. Our operations depend
substantially on our net interest income, which is the difference between the
interest income earned on our interest-earning assets, such as loans and
investments, and the interest expense paid on our interest-bearing liabilities,
such as deposits and other borrowings. Like most depository institutions, our
earnings are affected by changes in market interest rates and other economic
factors beyond our control. While we intend to continue to take measures to
decrease interest rate risk, these measures may not be effective in minimizing
the exposure to interest rate risk. The difference between the amount of
interest-earning assets and interest-bearing liabilities that mature within a
given period of time, or the interest rate sensitivity "gap," indicates the
extent to which an institution's interest rate spread will be affected by
changes in interest rates. A gap is considered positive when the amount of
interest rate-sensitive assets exceeds the amount of interest
 
                                       9
<PAGE>
rate-sensitive liabilities and is considered negative when the amount of
interest rate-sensitive liabilities exceeds the amount of interest
rate-sensitive assets. In a rising interest rate environment, an institution
with a positive gap would be in a better position than an institution with a
negative gap to invest in higher yielding assets or have its asset yields
adjusted upward, which would result in the yield on its assets increasing at a
faster pace than the cost of its interest-bearing liabilities. During a period
of falling interest rates, however, an institution with a positive gap would
tend to have its assets maturing at a faster rate than one with a negative gap,
which would tend to reduce or restrain the growth of its net interest income. If
we are unsuccessful in managing interest rate fluctuations, our business,
financial condition, results of operations and cash flows could be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Market Risk."
 
OUR OPERATIONS COULD BE INTERRUPTED IF OUR THIRD-PARTY SERVICE PROVIDERS
  EXPERIENCE DIFFICULTY OR TERMINATE THEIR SERVICES
 
    If our third-party service providers experience difficulties or terminate
their services and we are unable to replace them with another service provider,
our operations could be interrupted. If an interruption were to continue for a
significant period of time, our business, financial condition, results of
operations and cash flows could be materially adversely affected. We depend, and
will continue to depend, significantly on a number of relationships with
third-party service providers. Specifically, we receive essential Web hosting,
electronic bill payment and core systems processing services on an outsourced
basis from NCR Corporation, CheckFree Corporation and BISYS Group, Inc.,
respectively. See "Business--Operations."
 
OUR COMPUTER SYSTEMS, AND THOSE OF OTHERS ON WHOM WE RELY, MAY NOT OPERATE
  PROPERLY ON YEAR 2000-SENSITIVE DATES
 
    The year 2000 issue common to most corporations, including Net.B@nk,
concerns the inability of some computer software programs and databases to
recognize the year 2000 and other year 2000-sensitive dates. Computer programs
we or our service providers use that recognize a date using "00" as the year
1900 rather than the year 2000 could result in errors or system failures that
could ultimately cause us or our service providers to be unable to process
customer transactions. This would require us to cease operations pending
resolution of the problem. We believe our principal risk lies in the potential
inability of our outside vendors and service providers to process date-sensitive
information involving the year 2000. We also face risks relating to the
potential year 2000 noncompliance of other institutions that service our loans,
merchants receiving electronic transfers of funds from our customers, the
FedWire system governing electronic funds transfers, the ATM networks with which
we are is affiliated and the Federal Reserve system itself. Additionally, if any
of our borrowers encounter year 2000 computer malfunctions they may become
unable to repay their loans.
 
    Furthermore, if we are unable to achieve year 2000 readiness, our regulators
could suspend our operations. Although we are working to resolve the potential
impact of the year 2000 on the ability of the computerized information systems
we use to accurately process information that may be date-sensitive, if we or
any of our service providers or other entities cannot achieve year 2000
readiness, our business, financial condition, results of operations and cash
flows could be materially adversely affected. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000."
 
THE MARKET PRICE OF OUR COMMON STOCK HAS FLUCTUATED, AND COULD FLUCTUATE
  SIGNIFICANTLY IN THE FUTURE
 
    The market price of our common stock has been highly volatile since our
initial public offering, with closing prices ranging from a low of $2.92 per
share to a high of $78.34 per share. The market price of the common stock will
continue to fluctuate, and could fluctuate significantly, in response to
 
                                       10
<PAGE>
various factors and events, including the liquidity of the market for the common
stock, differences between our actual financial or operating results and those
expected by investors and analysts, changes in analysts' recommendations or
projections, new statutes or regulations or changes in the interpretation of
existing statutes and regulations affecting our business, changes in general
economic or market conditions and broad market fluctuations. See "Price Range of
Common Stock."
 
WE RELY ON INTELLECTUAL PROPERTY RIGHTS
 
    We regard the form and substance of our name as proprietary and attempt to
protect it by relying on intellectual property laws. We have submitted a United
States trademark registration for the Net.B@nk name and take active measures to
safeguard this name. Policing unauthorized use of proprietary information is
difficult, however, and we cannot assure you about the continued viability or
value of any of the intellectual property rights that we now have or may have in
the future. Litigation may be necessary in the future to enforce our
intellectual property rights.
 
    In addition, our business activities could infringe upon the proprietary
rights of others, and other parties could assert infringement claims against us.
Any litigation claims or counterclaims we might make could impair our business
because they could be time-consuming, result in costly litigation or divert
management's attention.
 
    We own the internet domain name "netbank.com". The regulation of domain
names in the United States and in foreign countries may change. Regulatory
bodies could establish additional top-level domains, appoint additional domain
name registrars or modify the requirements for holding domain names, any or all
of which may dilute the strength of our name. We may not acquire or maintain our
domain names in all of the countries in which our Web site may be accessed or
for any or all of the top-level domain names that may be introduced. The
relationship between regulations governing domain names and laws protecting
intellectual property rights is unclear. Therefore, we may not be able to
prevent third parties from acquiring domain names that infringe or otherwise
decrease the value of our trademarks and other intellectual property rights.
 
GOVERNMENT REGULATION MAY ADVERSELY AFFECT OUR ABILITY TO CONDUCT BUSINESS
 
    BANK REGULATION.  Revisions to existing or adoption of new laws or
regulations could subject us to more demanding regulatory compliance
requirements and could adversely affect our ability to conduct, or our cost of
conducting, business. Net.B@nk, Inc., the parent company, is regulated by the
Office of Thrift Supervision and the Georgia Department of Banking and Finance
and subject to certain restrictions imposed by the Board of Governors of the
Federal Reserve System. Net.B@nk, our banking subsidiary, is regulated by the
Office of Thrift Supervision and the FDIC. We are also subject to various laws
and regulations relating to commercial and consumer transactions generally, such
as the Uniform Commercial Code, as well as the electronic funds transfer rules
which are contained in Regulation E, issued by the Federal Reserve Board. Any of
these agencies, or other governmental or regulatory authorities, could revise
existing regulations or adopt new regulations at any time. Legislation and
regulatory initiatives containing wide-ranging proposals for altering the
structure, regulation and competitive relationships of financial institutions
are introduced regularly. We cannot predict whether or in what form a proposed
statute or regulation will be adopted or the extent to which it may affect our
business.
 
    Furthermore, given the rapid expansion of the electronic commerce market,
many regulatory bodies are adopting measures to ensure that their regulations
are keeping pace. For example, Congress has held hearings on whether to regulate
the electronic commerce market, while numerous states are considering adopting
their own laws to regulate internet banking. Furthermore, bank regulators are
considering proposing new laws relating to customer privacy. If enacted, these
laws, rules and regulations could force us to comply with more complex and
perhaps more burdensome regulatory
 
                                       11
<PAGE>
requirements, which could materially adversely affect our business, financial
condition, results of operations and cash flows. See "Business--Supervision and
Regulation."
 
    INTERNET REGULATION.  Our ability to conduct, and/or our cost of conducting,
business may also be adversely affected by a number of legislative and
regulatory proposals concerning other aspects of the internet, which are
currently under consideration by federal, state, local and foreign governmental
organizations. These proposals include, but are not limited to the following
matters: on-line content, user privacy, taxation, access charges, liability of
third-party activities and jurisdiction. Moreover, we do not know how existing
laws relating to these issues will be applied to the internet. The adoption of
new laws or the application of existing laws could decrease the growth in the
use of the internet, which could in turn decrease the demand for our products
and services, increase our cost of doing business or otherwise have a material
adverse effect on our business, financial condition, results of operations and
cash flows. Furthermore, government restrictions on internet content could slow
the growth of internet use and decrease acceptance of the internet as a
communications and commercial medium and thereby have a material adverse effect
on our business, financial condition and results of operations.
 
    Some local telephone carriers have asserted that the growing popularity and
use of the internet has burdened the existing telecommunications infrastructure
and caused interruptions in telephone service in areas with high internet use.
These carriers have petitioned the Federal Communications Commission to impose
access fees on internet service providers and commercial on-line service
providers. If the Federal Communications Commission imposes access fees, the
costs of transacting business over the internet could increase substantially,
potentially slowing the growth in use of the internet. This could in turn
decrease demand for our services or increase our cost of doing business, and
thus have a material adverse effect on our business, financial condition,
results of operations and cash flows.
 
   
    INTERNET PRIVACY.  Internet user privacy has become an issue both in the
United States and abroad. The Federal Trade Commission has proposed model
legislation that would force companies to comply with specified core information
practices. It is possible that Congress could adopt either legislation similar
to that proposed by the Federal Trade Commission or other privacy legislation
that could have a material adverse effect on the way in which we are allowed to
conduct our business, especially those aspects that involve the collection or
use of personal information. At the international level, the European Union has
adopted a directive that permits European Union member countries to impose
restrictions on the collection and use of personal data. This directive could,
among other things, affect United States companies that collect information over
the internet from individuals in European Union member countries and may impose
restrictions that are more stringent than current internet privacy standards in
the United States. In response to this directive, on November 4, 1998, the
United States Department of Commerce published for comment a set of safe harbor
principles regarding privacy protection for personally identifiable data. These
principles were revised on April 19, 1999.
    
 
OUR DIRECTORS AND EXECUTIVE OFFICERS OWN A SIGNIFICANT PORTION OF OUR
  OUTSTANDING COMMON STOCK AND COULD EXERCISE SIGNIFICANT INFLUENCE OVER
  NET.B@NK
 
   
    As of April 30, 1999, our directors and executive officers beneficially
owned 5,384,096 shares, representing approximately 20.0%, of the outstanding
common stock of Net.B@nk. As a result, our directors and executive officers
could exercise significant influence over matters requiring shareholder
approval, including the election of directors or a change in control of
Net.B@nk. See "Management" and "Principal Shareholders."

<PAGE>
OUR ARTICLES OF INCORPORATION AND BYLAWS COULD DETER A CHANGE IN CONTROL AND
  DEPRIVE YOU OF AN OPPORTUNITY TO SELL YOUR COMMON STOCK AT A PREMIUM OVER
  MARKET PRICES
 
    Our Articles of Incorporation and Bylaws contain provisions that may deter
an attempt to change or gain control of Net.B@nk. As a result, you may be
deprived of opportunities to sell some or all of your shares at prices that
represent a premium over market prices. These provisions include the existence
of blank check preferred stock, staggered terms for the directors, restrictions
on the ability to change the number of directors or to remove a director and
supermajority voting requirements. See "Description of Capital Stock."
 
WE DO NOT INTEND TO PAY CASH DIVIDENDS
 
    We do not intend to pay cash dividends in the foreseeable future, as we
expect to apply any earnings to developing and expanding our business. See
"Dividend Policy."
 
THE MARKET PRICE OF THE COMMON STOCK MAY DECLINE DUE TO SHARES ELIGIBLE FOR
  FUTURE SALE
 
    Future sales of substantial amounts of common stock in the public market or
the perception that such sales could occur could adversely affect the market
price of the common stock. Certain directors and executive officers of Net.B@nk,
who collectively hold 5,172,096 restricted shares of common stock, are precluded
under Office of Thrift Supervision requirements from selling any of these shares
of common stock without prior Office of Thrift Supervision approval until July
28, 2000. If all of these shares are sold when they first become eligible for
resale, the increase in the number of shares available for sale could adversely
affect the market price of the common stock.
 
WE HAVE BROAD DISCRETION IN ALLOCATING THE NET PROCEEDS FROM THIS OFFERING

                           FORWARD-LOOKING STATEMENTS
 
    Some of the statements in this prospectus are forward-looking statements.
These forward-looking statements include statements in the "Business-Industry
Background" and "The Net.B@nk Solution" sections of this prospectus relating to
trends in internet use and electronic commerce. These forward-looking statements
also include statements relating to our performance in the "Management's
Discussion and Analysis of Financial Condition and Results of Operations," "Use
of Proceeds" and "Business" sections of this prospectus. In addition, we may
make forward-looking statements in future filings with the Securities and
Exchange Commission and in written materials, press releases and oral statements
issued by us or on our behalf. Forward-looking statements include statements
regarding the intent, belief or current expectations of Net.B@nk or its officers
and can be identified by the use of forward-looking terms such as "may," "will,"
"should," "believe," "expect," "anticipate," "estimate," "continue" or the
negative of these words or comparable terminology. Forward-looking statements
relating to the following involve inherent risks and uncertainties:
 
    - The growth in the use of the internet;
 
    - Our business strategy;
 
    - Competitiveness in the banking industry;
 
    - Potential regulatory obligations; and
 
    - Other statements that are not historical facts.
 
    Our actual results could differ materially from those anticipated from the
forward-looking statements, depending on various important factors. These
factors include:
 
    - A possible decline in asset quality;
 
    - The evolving nature of the market for internet banking;
 
    - The possible adverse effects of unexpected changes in the interest rate
      environment; and
 
    - Increasing competition and regulatory changes.
 
    In addition, please note that matters set forth under the caption "Risk
Factors" constitute cautionary statements identifying important factors with
respect to the forward-looking statements, including risks and uncertainties,
that could cause actual results to differ materially from those in the
forward-looking statements.
 
    All forward-looking statements in this prospectus are based on information
available to us as of the date of this prospectus. We do not undertake to update
any forward-looking statements that may be made by us or on our behalf in this
prospectus or otherwise.

                                USE OF PROCEEDS
 
   
    We estimate that the net proceeds to us from our sale of 3,000,000 shares of
common stock in this offering, after payment of underwriting discounts and
commissions and estimated expenses of the offering, will be $176,200,000,
assuming an offering price of $62.00 per share. If the underwriters exercise
their over-allotment option in full, we estimate that the net proceeds to us
will be $202,705,000 after payment of underwriting discounts and commissions and
estimated expenses of the offering. We intend to invest the majority of the net
proceeds from this offering in earning assets, including purchased loan
portfolios, new loans that we originate and investment securities. We intend to
use the earnings from these assets and the balance of the net proceeds from this
offering for general corporate purposes, including increasing our budgeted
marketing efforts to $11.0 million for the next twelve months. We also intend to
hire additional personnel, to fund other costs related to our accelerated
deposit growth and to pursue strategic partnerships and investments. We have not
yet allocated the net proceeds to each of the proposed purposes. Although we
continually evaluate opportunities for strategic partnerships and investments,
we do not presently have an understanding or agreement relating to any such
arrangement that is material to our business or that we have not otherwise
disclosed in this prospectus.
    
 
    Concurrent with this offering and by means of a separate prospectus, we are
offering $100,000,000 aggregate principal amount of   % Convertible Subordinated
Notes Due 2004, plus an additional $15,000,000 aggregate principal amount of
notes, solely to cover the underwriters' over-allotment option. The notes are
convertible, at the option of the holder, into shares of common stock at a
conversion price of $            per share, which is equivalent to       shares
per $1,000 principal amount of the notes, subject to anti-dilution adjustments.
The notes rank junior in right of payment to substantially all of our senior
indebtedness in existence at the time of the issuance of the notes or incurred
by us in the future. In addition, the notes are subordinate to all existing and
future liabilities of our subsidiaries, including our obligations to depositors
and trade and other creditors. The completion of the notes offering and this
common stock offering do not depend upon one another. We intend to use the
proceeds from the notes offering for the same purposes as for the common stock
offering.

offering price of $62.00 per share. If the underwriters exercise their

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
    Net.B@nk, Inc. is a holding company that wholly owns Net.B@nk, a federal
savings bank. Net.B@nk, Inc. was incorporated as a Georgia corporation on
February 20, 1996, for the purpose of forming and, ultimately, operating a
wholly owned federal savings bank subsidiary. During the period from February
20, 1996 to July 31, 1997, pending regulatory approval and the acquisition of a
bank charter, we operated as a development stage enterprise under an agreement
with Carolina First Bank, a wholly owned subsidiary of Carolina First
Corporation. Carolina First Bank agreed to hold and service the deposit accounts
we generated in exchange for 3,975,000 shares of common stock, which were valued
at $3.8 million. In addition, during the period from February 20, 1996 to July
31, 1997, we were a party to an agreement with First Alliance/Premier
Bancshares, Inc. pursuant to which we agreed to purchase the charter of First
Alliance's subsidiary, Premier Bank, $5.0 million in loans, $5.0 million in
certificates of deposit and $2.0 million in unimpaired capital in exchange for
$2.2 million in cash, 124,218 shares of the common stock valued at $125,000 and
$75,000 in additional cash for reimbursement of direct out-of-pocket expenses.
On July 11, 1997, we received final regulatory approval from the Office of
Thrift Supervision to purchase the bank charter from First Alliance. On July 31,
1997, we received approximately $38.4 million in net proceeds from the sale of
10,500,000 shares of our common stock in our initial public offering and
consummated our agreements with both First Alliance and Carolina First Bank. As
a result, Net.B@nk became a wholly owned subsidiary of Net.B@nk, Inc. As of
March 31, 1999, we had 24,634 accounts and approximately $332.7 million in
deposits.
 
    On April 13, 1999, we declared a 3 for 1 split of our common stock effected
in the form of a stock dividend payable on May 14, 1999 to shareholders of
record as of the close of business on April 23, 1999. All references to share
and per share amounts have been retroactively adjusted to reflect this split.
 
FINANCIAL CONDITION
 
    Our assets were $526.5 million at March 31, 1999 compared to $388.4 million
and $93.2 million at December 31, 1998 and 1997, respectively. The increase of
$138.1 million from December 31, 1998 to March 31, 1999 was primarily the result
of approximately $105.0 million of net proceeds we received from an offering of
common stock in February 1999, as well as an increase in customer deposits of
approximately $49.1 million. We are using the proceeds from both the February
1999 offering of common stock and the increase in customer deposits for our
widespread marketing campaign to increase public awareness of the Net.B@nk name
and our products and services, and investing the excess in federal funds sold,
investment securities and loans.
 
    The increase in assets of $295.2 million from December 31, 1997 to December
31, 1998 was primarily due to growth in our loan portfolio resulting from our
purchase of approximately $257.5 million in home equity loans and first and
second mortgage loans and the purchase of approximately $41.4 million in
investment securities during the year ended December 31, 1998. In addition, we
recorded a $2.3 million deferred tax asset related primarily to previous net
operating loss carryforwards that we expect to realize for tax purposes. Because
we achieved profitability in 1998, we believe that it is more likely than not
that our deferred tax assets will be realized. We also had loan sale proceeds
receivable of $23.2 million related to loan origination agreements with third
parties at December 31, 1998.
 
    Total liabilities increased $33.0 million from $349.7 million at December
31, 1998 to $382.7 million at March 31, 1999. This increase was primarily due to
the rapid growth in our deposit portfolio of $49.1 million as a result of our
marketing campaign, offset by a $15.0 million decrease in other borrowed funds.
Total liabilities increased $290.6 million from $59.1 million at December 31,
1997 to
 
                                       19
<PAGE>
$349.7 million at December 31, 1998. This increase was primarily due to the
rapid growth of our deposit portfolio as a result of marketing programs we
introduced in the fourth quarter of 1997.
 
    Total shareholders' equity increased $105.0 million from December 31, 1998
to March 31, 1999 primarily due to our receipt of approximately $105.0 million
from the sale of 7,290,000 shares of our common stock in a public offering.
Total shareholders' equity increased $4.6 million from December 31, 1997 to
December 31, 1998 as a result of net income of $4.5 million and comprehensive
income of $82,000.

1998.

RESULTS OF OPERATIONS
 
THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31, 1998
 
    GENERAL.  Net income for the three months ended March 31, 1999 amounted to
$692,000, an increase of $843,000 compared to a $151,000 loss for the three
months ended March 31, 1998. The increase in net income was the result of the
growth of our operations from 1998 to 1999.
 
    INTEREST INCOME.  Interest income related to our loan and investment
portfolio for the three months ended March 31, 1999 was $7.6 million compared to
$2.2 million for the three months ended March 31, 1998. The increase in interest
income was a result of the growth of our loan portfolio of $258.3 million from
March 31, 1998 to March 31, 1999, offset partially by a decrease in the average
yield on loans from 8.02% for the three months ended March 31, 1998 to 7.55% for
the three months ended March 31, 1999. In addition, the investment portfolio
grew from $46.3 million at March 31, 1998 to $80.3 million at March 31, 1999.
The yield on the investment portfolio was 5.63% for the three months ended March
31, 1998 compared to 6.20% for the three months ended March 31, 1999.
 
    INTEREST EXPENSE.  For the three months ended March 31, 1999, we recorded
$4.0 million in interest expense on deposits compared to $1.3 million for the
three months ended March 31, 1998 as a result of our increase in customer
deposits from $128.7 million at March 31, 1998 to $332.7 million at March 31,
1999. In addition, interest paid on deposits decreased from 5.54% for the three
months ended March 31, 1998 to 5.29% for the three months ended March 31, 1999.
Also, during the three months ended March 31, 1999, we recorded approximately
$500,000 in interest expense associated with short-term borrowings under our
line of credit agreements and advances from the Federal Home Loan Bank.
 
    NET INTEREST INCOME.  Net interest income is determined by our interest rate
spread, which is the difference between the yields earned on our
interest-earning assets and the rates paid on our interest-bearing liabilities,
and the relative amounts of interest-earning assets and interest-bearing
liabilities. Net interest income was $3.0 million for the three months ended
March 31, 1999 compared to $903,000 for the three months ended March 31, 1998.
The increase in net interest income resulted from the increase in the amount of
loans and deposits from March 31, 1998 to March 31, 1999.
 
    PROVISION FOR LOAN LOSSES.  In connection with the purchase of loan
portfolios, we assess the inherent loss in the portfolios and record the
necessary allowance by adjusting the premium associated with each portfolio.
During the three months ended March 31, 1999, we recorded $1.2 million as an
addition to premiums related to allowance for loan losses for loans purchased
during the quarter. In addition, we also recorded a provision for loan losses of
$49,800 related primarily to a decline in credit quality of a specific pool of
automobile loans. This compared to a provision of $4,000 recorded during the
three months ended March 31, 1998. We periodically review the performance of our
loan portfolio by reviewing charge-offs, delinquency statistics and industry
statistics on a pool by pool basis for our purchased portfolio and a loan by
loan basis for our originated loans. If we note a decline in credit quality for
a specific pool or loan, we record an additional allowance through a charge to
the provision for loan losses. We maintain the allowance for loan losses at a
level that we estimate to be adequate to provide for probable losses in the loan
portfolio. We determine the adequacy of the allowance based upon reviews of
individual loans, recent loss experience, current economic conditions, the risk
characteristics of the various categories of loans and other pertinent factors.
 
    NONINTEREST INCOME.  For the three months ended March 31, 1999, we recorded
approximately $246,000 in loan and deposit service charges and fees compared to
$123,000 recorded during the three months ended March 31, 1998. The significant
increase in service charges was a result of a significant increase in both the
loan and deposit portfolios.
 
                                       22
<PAGE>
    NONINTEREST EXPENSES.  Noninterest expenses include all operating expenses,
including salaries and benefits, marketing, general and administrative expenses
(excluding interest expense, provision for loan losses and income taxes).
Noninterest expense increased 83%, or $1.0 million, for the three months ended
March 31, 1999 compared to the three months ended March 31, 1998. This increase
was primarily the result of increases in salaries and benefits, customer service
and data processing as we added additional employees and operational activities
to support additional customers, and an increase in marketing expense as we
expanded our marketing programs to build public awareness of the Net.B@nk name
and our products and services.
 
YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997
 
    GENERAL.  Net income for the year ended December 31, 1998 amounted to $4.5
million, an increase of $10.1 million compared to the $5.6 million loss for the
year ended December 31, 1997. The statement of operations for the year ended
December 31, 1997 reflects our operations before and immediately following the
acquisition of our bank charter. Because we did not acquire the charter until
July 31, 1997, we had no earning assets prior to that date. A substantial
portion of the income for the year ended December 31, 1998 resulted from the
recognition of $2.3 million in tax benefits. The benefits resulted from the
reversal of a valuation allowance of $3.3 million previously associated with our
deferred tax assets offset by income tax expense for the year ended December 31,
1998. Because we achieved profitability during 1998, we now believe it is more
likely than not that the deferred tax assets will be realized.
 
    INTEREST INCOME.  Interest income related to our loan and investment
portfolio for the year ended December 31, 1998 was $18.1 million compared to
$2.2 million for the year ended December 31, 1997. The increase is a result of
the growth of our loan portfolio from $44.9 million at December 31, 1997 to
$280.4 million at December 31, 1998 offset by a decrease in average yield from
8.70% for the year ended December 31, 1997 to 7.97% for the year ended December
31, 1998. In addition, the investment security portfolio grew from $18.1 million
at December 31, 1997 to $59.5 million at December 31, 1998 as we invested cash
received from customer deposits. The yield on the investment portfolio was 7.06%
for the year ended December 31, 1997 compared to 6.01% for the year ended
December 31, 1998.
 
    INTEREST EXPENSE.  For the year ended December 31, 1998, we recorded $10.2
million in interest expense on deposits as a result of our increase in customer
deposits from $58.7 million at December 31, 1997 to $283.6 million at December
31, 1998. In addition, the average interest rate paid on deposits increased from
5.17% for the year ended December 31, 1997 to 5.77% for the year ended December
31, 1998. We recorded interest expense on deposits of $1.3 million during the
year ended December 31, 1997 as we transferred our deposits to our banking
subsidiary from Carolina First Bank and began paying interest on those deposits.
In addition, during the year ended December 31, 1998, we recorded approximately
$1.2 million of interest expense associated with other borrowed funds under our
line of credit agreements and Federal Home Loan Bank advances.
 
    NET INTEREST INCOME.  Net interest income is determined by our interest rate
spread, which is the difference between the yields earned on our
interest-earning assets and the rates paid on our interest-bearing liabilities,
and the relative amounts of interest-earning assets and interest-bearing
liabilities. With the growth in our operations, net interest income increased to
$6.7 million for the year ended December 31, 1998, compared to $963,000 for the
year ended December 31, 1997.
 
    PROVISION FOR LOAN LOSSES.  During 1998, we recorded $3.6 million as an
addition to premium related to allowance for loan losses for purchased loans. In
addition, we recorded a $20,000 provision for loan losses for the year ended
December 31, 1998, compared to $472,000 recorded during the year ended December
31, 1997 for declines in credit quality on a specific pool of automobile loans
and additional allowance related to originated loans.
 
                                       23
<PAGE>
    NONINTEREST INCOME.  For the year ended December 31, 1998, we recorded
approximately $683,000 in loan and deposit service charges and fees compared to
$63,000 recorded during the year ended December 31, 1997. The significant
increase in service charges was driven by the significant increase in both the
loan and deposit portfolios.
 
    NONINTEREST EXPENSES.  Noninterest expenses decreased approximately $944,000
for the year ended December 31, 1998 compared to the year ended December 31,
1997. The primary component of the decrease during the year ended December 31,
1998 was a $1.4 million decrease in the amortization of the service contract
with Carolina First Bank as the service contract was fully amortized during the
second quarter of 1997. In addition, salaries and benefits decreased $1.0
million as we outsourced certain services and paid $450,000 of bonuses to our
employees upon completion of our initial public offering in July 1997. These
decreases were partially offset by increases in marketing, customer service,
data processing, occupancy and other expenses as we moved to our new offices and
began soliciting and serving new deposit customers.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO THE PERIOD FROM FEBRUARY 20, 1996 TO
  DECEMBER 31, 1996
 
    GENERAL.  We did not have any earning assets until July 31, 1997, when we
acquired our bank charter. The net loss for the year ended December 31, 1997 was
$5.6 million, an increase of $1.8 million when compared to the period from
February 20, 1996 to December 31, 1996. The statement of operations for the
period from February 20, 1996 to December 31, 1996 reflects the initial phase of
our operations, including the acquisition, testing and implementation of the
internet banking platform, marketing expenses and the accrual of Carolina First
Bank's expense reimbursements. Under the servicing agreement with Carolina First
Bank, customer deposits and the related assets resulting from our marketing
efforts, which began in August 1996, were included in Carolina First Bank's
financial operations.
 
    INTEREST INCOME.  Interest income for the year ended December 31, 1997 was
$2.2 million. We did not record a significant amount of interest income for the
period from February 20, 1996 to December 31, 1996 because we had no investments
or loans during that period. On July 31, 1997, we received the net proceeds from
our initial public offering and customer deposits held by Carolina First Bank
and invested those funds in federal funds, mortgage-backed securities and loans
purchased from Carolina First Bank and an independent third party.
 
    INTEREST EXPENSE.  Because we did not begin soliciting deposit accounts
until October 1996, we did not record any interest expense for the period from
February 20, 1996 to December 31, 1996. On July 31, 1997, based on the terms of
the servicing agreement with Carolina First Bank and the charter purchase
agreement, Carolina First Bank and First Alliance transferred approximately
$47.8 million in customer deposits and related assets to Net.B@nk. We recorded
approximately $1.3 million of interest expense during the year ended December
31, 1997. This amount includes $163,479 of net interest expense, which
represents the difference between interest expense paid to customers and
interest income paid to Net.B@nk by Carolina First Bank at the contractual rates
in the servicing agreement prior to July 31, 1997.
 
    NET INTEREST INCOME.  Net interest income is determined by our interest rate
spread, which is the difference between the yields earned on our
interest-earning assets and the rates paid on our interest-bearing liabilities,
and the relative amounts of interest-earning assets and interest-bearing
liabilities. Net interest income was $963,000 for the year ended December 31,
1997. Because we did not receive our bank charter until July 31, 1997, we were
not allowed to hold investments, loans or customer deposits during the period
from February 20, 1996 to December 31, 1996, and therefore, no significant
amount of net interest income was recorded for the period from February 20, 1996
to December 31, 1996.
 
                                       24
<PAGE>
    PROVISION FOR LOAN LOSSES.  We purchased our first loans during the period
from July 31, 1997 to December 31, 1997. During this period, we recorded a
provision for loan losses of $472,000 for a decline in credit quality related to
a specific pool of automobile loans and an additional allowance related to
originated loans.
 
    NONINTEREST INCOME.  For the period from July 31, 1997 to December 31, 1997,
we recorded approximately $63,000 in loan and deposit service charges and fees.
We recorded only miscellaneous management fees received of $60,000 during the
period from February 20, 1996 to December 31, 1996.
 
    NONINTEREST EXPENSES.  Noninterest expenses increased $2.2 million from $3.9
million during the period from February 20, 1996 to December 31, 1996 to $6.1
million for the year ended December 31, 1997. The primary components of the
increase were an increase of $1.6 million in salaries and benefits, which
reflects the payment of approximately $450,000 in bonuses to employees; the
amortization of approximately $343,000 in stock plan expense; increases of
$305,000, $391,000 and $236,000 in customer service, data processing and
marketing, respectively, reflecting the growth of our deposit base and related
support functions; and an increase of approximately $260,000 in other operating
expenses consisting primarily of legal and accounting fees. These increases were
offset by a $960,000 decrease in the amortization of the service contract with
Carolina First Bank as the service contract was fully amortized during the
second quarter of 1997. The expenses for the period from February 20, 1996 to
December 31, 1996 reflect only the initial phase of our operations, including
the acquisition, testing and implementation of our internet banking platform,
marketing expenses and the accrual of Carolina First Bank's expense
reimbursements.

    In connection with the issuance of some of the options during the year ended

upon completion of the initial public offering, and we recognized $319,704 of
unamortized compensation expense. The other options vest one-third on the first
anniversary of the date of issuance, one-third on the second anniversary of the
date of issuance and one-third on the third anniversary of the date of issuance.
Of the vested options, 708,423 cannot be exercised and sold until July 28, 2000

MARKET RISK
 
    ASSET AND LIABILITY MANAGEMENT.  Our principal business is the originating
and purchasing of loans, funded by customer deposits and, to the extent
necessary, other borrowed funds. Consequently, a significant portion of our
assets and liabilities are monetary in nature and fluctuations in interest
rates, specifically the prime rate, will affect our future net interest income
and cash flows. This interest rate risk is our primary market risk exposure. We
do not enter into derivative financial instruments such as futures, forwards,
swaps and options. Also, we have no market risk-sensitive instruments held for
trading purposes. Our exposure to market risk is reviewed on a regular basis by
our management.
 
    The following table sets forth the interest rate risk of our assets and
liabilities as of December 31, 1997.

    We measure interest rate sensitivity as the difference between the amount of
interest-earning assets and interest-bearing liabilities that mature within a
given period of time. The difference, or the interest rate sensitivity "gap,"
provides an indication of the extent to which an institution's interest rate
spread will be affected by changes in interest rates. The above table does not
consider interest rate adjustments on our adjustable rate loans. A gap is
considered positive when the amount of interest-rate sensitive assets exceeds
the amount of interest-rate sensitive liabilities and is considered negative
when the amount of interest-rate sensitive liabilities exceeds the amount of
interest-rate sensitive assets. In a rising interest rate environment, an
institution with a positive gap would be in a better position than an
institution with a negative gap to invest in higher yielding assets or have its
asset yields adjusted upward, which would result in the yield on its assets
increasing at a faster pace than the cost of its interest-bearing liabilities.
During a period of falling interest rates, however, an institution with a
positive gap would tend to have its assets maturing at a faster rate than one
with a negative gap, which would tend to reduce or restrain the growth of its
net interest income.

    A savings institution generally may not make loans to one borrower and
related entities in an amount which exceeds 15% of its unimpaired capital and
surplus, although loans in an amount equal to an additional 10% of unimpaired
capital and surplus may be made to a borrower and its related entities if the
loans are fully secured by readily marketable securities. At March 31, 1999, our
limit on loans to one borrower was approximately $21.6 million (15% unimpaired
capital and surplus). At March 31, 1999, we had not made any loans to any one
borrower, including persons or entities related to the borrower, exceeding the
limitation.

    ASSET QUALITY AND NONPERFORMING ASSETS.  During the years ended December 31,
1998 and 1997 and the three months ended March 31, 1999, we did not have any
significant loans on nonaccrual status, significant loans past due 90 days or
more or restructured loans.
 
    CONCENTRATIONS OF CREDIT RISK.  At December 31, 1998, a majority of our
loans were with customers residing in the Western and Southeastern United
States. At December 31, 1997, all of our loans were with customers residing in
the Southeastern United States.
 
    ALLOWANCE FOR LOAN LOSSES.  The allowance for loan losses is maintained at a
level management considers adequate to provide for probable losses in the loan
portfolio. As the majority of our portfolio is purchased, we make an estimate of
the loss inherent in the purchased portfolio based on industry statistics and
record an allowance for loan losses by adjusting the premium associated with the
purchased loans. We periodically review the adequacy of the allowance based upon
reviews of individual loans and loan pools, recent loss experience, current
economic conditions, the risk characteristics of the various pools of loans, or
individual loans, industry statistics and other pertinent factors. If we note a
decline in credit quality for a specific loan pool or a loan, we record an
additional allowance through a charge to the provision for loan losses. Loans
that we deem uncollectible are charged to the allowance. We also add provisions
for loan losses and recoveries on loans previously charged off to the allowance.
 
    Although we use the best information available to make determinations with
respect to the provisions for loan losses, additional provisions for loan losses
may be necessary in the future should economic or other conditions change
substantially. In addition, the Office of Thrift Supervision, as an integral
part of the examination process, periodically reviews our allowance for loan
losses. The agency may require us to recognize additions to the allowance based
on their judgments about the information available to them at the time of their
examination.
 
    The following table sets forth an analysis of our allowance for loan losses
during the years ended December 31, 1997 and 1998:

    INVESTMENT SECURITIES.  Our investment policy, as established by the Board
of Directors, is designed primarily to provide and maintain liquidity and to
generate a favorable return on investments without incurring undue interest rate
risk, credit risk and investment portfolio asset concentrations. Our investment
policy is currently implemented by the investment committee within the
parameters set by the Board of Directors.
 
    We are authorized to invest in obligations issued or fully guaranteed by the
United States government, certain federal agency obligations, certain time
deposits, negotiable certificates of deposit issued by commercial banks and
other insured financial institutions, investment grade corporate debt securities
and other specified investments.
 
    Securities classified as available for sale are reported at fair value, with
unrealized gains and losses, net of tax, excluded from earnings and reported in
other comprehensive income. At March 31, 1999 and December 31, 1998 and 1997,
all of our investment securities were classified as available for sale. At March
31, 1999 and December 31, 1998 and 1997, investments in the debt and/or equity
securities of any one issuer did not exceed more than 10% of our shareholders'
equity.

SOURCES OF FUNDS
 
    GENERAL.  Our primary sources of funds are deposits, borrowings, prepayments
and maturities of outstanding loans, sales of loans, maturities of investment
securities and other short-term investments and funds provided from operations.
While scheduled loan payments and maturing investment securities and short-term
investments are relatively predictable sources of funds, deposit flows and loan
prepayments are greatly influenced by general interest rates, economic
conditions and competition. We invest excess funds in overnight deposits and
other short-term interest-earning assets. We can use cash generated through the
retail deposit market, our traditional funding source, to offset the cash
utilized in investing activities. Our available-for-sale securities and
short-term interest-earning assets can also be used to provide liquidity for
lending and other operational requirements. As an additional source of funds, we
had $40.0 million of availability under existing line of credit agreements at
March 31, 1999. See note 8 of the notes to our consolidated financial
statements.
 
    DEPOSITS.  Our deposit products include a broad selection of deposit
instruments, including commercial checking accounts, negotiable order of
withdrawal accounts, money market accounts and
 
                                       32
<PAGE>
term certificate accounts. Deposit account terms vary, with the principal
differences being the minimum balance required, the time periods the funds must
remain on deposit and the interest rate.
 
    We utilize nontraditional marketing methods to attract new customers and
savings deposits. Our target market includes internet users, on-line shoppers
and special niche customers. We market our products and services by placing
banner advertisements on portals and Web sites that we believe will attract our
target customers. We also derive a marketing benefit from media coverage.
Additionally, we continually seek to form product and marketing alliances with
other financial services providers to broaden our product and service offerings
and appeal to a broader customer base.
 
    We are competitive in the types of accounts and range of interest rates we
offer on our deposit products. Our deposit levels have increased during the
years ended December 31, 1998 and 1997, primarily as a result of competitive
rates we offer and internet advertising. The weighted average interest rate paid
during the years ended December 31, 1998 and 1997 was 5.77% and 5.17%,
respectively. Although market demand generally dictates which deposit maturities
and rates will be accepted by the public, we intend to continue to promote
checking and negotiable order of withdrawal accounts as well as longer term
certificates of deposit to the extent possible and consistent with asset and
liability management goals.
 
    The following table sets forth the dollar amount of deposits and weighted
average interest rates in the various types of deposit programs offered by us at
December 31, 1997 and 1998 and March 31, 1999, respectively:

    CAPITAL RESOURCES.  We are subject to various regulatory capital
requirements administered by the federal banking agencies. Our failure to meet
minimum capital requirements can initiate certain mandatory and possibly
additional discretionary actions by regulators that, if undertaken, could have a
direct material effect on our consolidated financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
we must meet specific capital guidelines that involve quantitative measures of
our assets, liabilities and certain off-balance-sheet items as calculated under
regulatory accounting practices. Our capital amounts and classifications are
also subject to qualitative judgments by the regulators about components, risk
weightings and other factors. In addition, under regulatory guidelines,
Net.B@nk, our banking subsidiary, may not pay a dividend to Net.B@nk, Inc., if
doing so would cause Net.B@nk to be less than adequately capitalized, as defined
below.
 
    Quantitative measures established by regulation to ensure capital adequacy
require Net.B@nk to maintain minimum amounts and ratios, as set forth in the
table below. Net.B@nk's primary regulatory agency, the Office of Thrift
Supervision, requires Net.B@nk to maintain minimum ratios of tangible capital to
tangible assets of 1.5%, core capital to tangible assets of 3.0% and total
risk-based capital to risk-weighted assets of 8.0%. We believe that as of
December 31, 1998 Net.B@nk met all the capital adequacy requirements to which it
was subject.
 
    As of December 31, 1998, the most recent notification from the Office of
Thrift Supervision categorized Net.B@nk as well capitalized under the regulatory
framework for prompt corrective action. To be well capitalized Net.B@nk must
maintain minimum total risk-based, Tier I risk-based and Tier I leverage ratios
as set forth in the table. No conditions or events have occurred since that
notification that we believe would change Net.B@nk's category.
 
    On February 10, 1999, we received net proceeds of approximately $105.0
million from the sale of 7,290,000 shares of our common stock in a public
offering.

    At March 31, 1999, Net.B@nk had total, core, tangible and Tier I capital
ratios of 35.81%, 24.64%, 24.64% and 35.24%, respectively.
 
    Under current Office of Thrift Supervision regulations, Net.B@nk may pay
dividends and make other capital distributions after giving notice to the Office
of Thrift Supervision.
 
    During the year ended December 31, 1998, Net.B@nk, Inc. and its sole
subsidiary, Net.B@nk, entered into line of credit agreements with The Bankers
Bank. Net.B@nk, Inc. is a party to one such agreement and its sole subsidiary,
Net.B@nk, is a party to two such agreements. Under the terms of our agreement
that expired on October 20, 1998, Net.B@nk, Inc. could borrow 50.0% of the
tangible equity of Net.B@nk, up to $17.0 million, using the stock of Net.B@nk as
collateral. Any amounts borrowed under this line had interest at a fixed rate of
8.0% per annum. During the year ended December 31, 1998, Net.B@nk borrowed and
repaid $12.0 million under the line. Under the terms of the other two
agreements, Net.B@nk may borrow $5.0 million under an unsecured general purpose
line and 99.0% of the value of its investment securities under another line.
Both of the lines bear interest at 25 basis points above the Federal Funds rate,
or 5.0%, at December 31, 1998. Under these agreements at December 31, 1998,
Net.B@nk had an outstanding borrowing of $20.0 million with no stated maturity
secured by investment securities.
 
    During the three months ended March 31, 1999, Net.B@nk repaid $20.0 million
of borrowings outstanding under its line of credit agreement with The Bankers
Bank and $20.0 million under one of its line of credit agreements with the
Federal Home Loan Bank.
 
    As of March 31, 1999, Net.B@nk had borrowed $20.0 million from the Federal
Home Loan Bank at a fixed rate of 4.43%. The borrowing is callable at the second
anniversary date. If not called at the second anniversary date, the borrowing
extends for an additional three years at 4.43%. Also, Net.B@nk has borrowed
$25.0 million from the Federal Home Loan Bank at a fixed rate of 4.64%. The
borrowing is callable at the second anniversary date. If not called at the
second anniversary date, the borrowing extends for an additional eight years at
4.64%. These borrowings are secured by Net.B@nk's investment securities.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
    As of January 1, 1998, we adopted Statement of Financial Accounting
Standards 130, REPORTING COMPREHENSIVE INCOME, and restated prior periods to
conform to the presentation required by
 
                                       35
<PAGE>
SFAS 130. SFAS 130 establishes new rules for the reporting and display of
comprehensive income and its components. SFAS 130 requires unrealized gains or
losses, net of tax, on our available-for-sale securities, which prior to
adoption were reported separately in shareholders' equity, to be included in
other comprehensive income. The adoption of SFAS 130 had no impact on our net
income or shareholders' equity.
 
    As of April 1, 1998, our adopted Statement of Position 98-1, ACCOUNTING FOR
THE COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED FOR INTERNAL USE. SOP 98-1
allows for the capitalization of costs related to the development and
implementation of software obtained for internal use including materials,
payroll and interest costs once the criteria of the SOP have been met. As of
December 31, 1998, $592,402 of these related costs had been capitalized.
 
    As of December 31, 1998, we adopted Statement of Financial Accounting
Standards 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED
INFORMATION. SFAS 131 establishes annual and interim reporting standards for an
enterprise's business segments and related disclosures about its products,
services, geographic areas and major customers. The adoption of SFAS 131 had no
effect on our financial statements for the year ended December 31, 1998 because
we only had one reportable segment.
 
    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND
HEDGING ACTIVITIES. SFAS 133 establishes standards for derivative instruments
and hedging activities and requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. SFAS 133 is effective for all fiscal quarters
of fiscal years beginning after June 15, 1999. The adoption of SFAS 133 is not
expected to have a significant effect on our financial statements.
 
YEAR 2000
 
    We are working to resolve the potential impact of the year 2000 on the
ability of the computerized information systems we use to accurately process
information that may be date sensitive. Any of the programs we or our service
providers use that recognize a date using "00" as the year 1900 rather than the
year 2000 could result in errors or system failures that could ultimately cause
us or our service providers to become unable to process customer transactions.
This would require us to cease operations pending resolution of the problem.
Such an eventuality would materially adversely affect our business, financial
condition and results of operations. Accordingly, we are devoting significant
attention to identifying year 2000 issues and testing our in-house and external
systems for year 2000 compliance. To date, we have incurred year 2000
remediation costs of approximately $21,000 and have budgeted approximately
$35,000 for total remediation costs. We have been utilizing working capital to
fund our year 2000 compliance program and anticipate that we will continue to do
so.
 
    We began testing our in-house information technology systems during the
second quarter of 1998 and completed this testing during the third quarter of
1998. We have not identified, and do not anticipate, any significant risks or
issues relating to non-information technology systems.
 
    We are also assessing the year 2000 compliance of our outside vendors and
service providers. Because we primarily contract with outside vendors for our
computer application programs, we believe our principal risk relating to year
2000 issues lies in the potential inability of those vendors to process date
sensitive information involving the year 2000. We began testing the systems
provided by these vendors for year 2000 compliance in the third quarter of 1998
and have an Office of Thrift Supervision-mandated completion date of June 30,
1999. In addition, we are contacting each of our vendors to obtain a commitment
that they are or will timely be year 2000 compliant. If such assurances are not
forthcoming, or if we believe for any reason that any of our vendors will not be
year 2000 compliant when required, we plan to contract with other vendors that
would be able to provide similar services at
 
                                       36
<PAGE>
similar costs. Although we cannot offer any assurances, we believe that such
vendors are and will be available. Alternatively, we could bring the outsourced
services in-house by licensing the applicable software and converting it to run
on our platforms or form a correspondent relationship with an unaffiliated year
2000 compliant bank that could service our customers and accounts until we could
provide such services on a year 2000 compliant basis. We believe we could
implement any of the foregoing contingency plans without a material interruption
in our business and without a material adverse effect on our financial
condition, results of operations or cash flows.

    Basic and diluted net income (loss) per common and common equivalent share
have been calculated based on the weighted average number of shares outstanding
during the quarter in accordance with SFAS 128. Potential common shares have not
been included in the calculation related to those quarters with a net loss
because they were antidilutive. All previously reported per share amounts have
been restated to conform to SFAS 128. The total for the quarters differs from
the net loss per share as shown on the statement of operations because of the
issuance of common shares during the year of 1997. On April 13, 1999, we
declared a 3 for 1 split of our common stock effected in the form of a stock
dividend payable on May 14, 1999 to shareholders of record as of the close of
business on April 23, 1999. All references to share and per share amounts have
been retroactively adjusted to reflect the split.

OVERVIEW
 
    Net.B@nk, our sole subsidiary, is the largest federally-insured bank
operating exclusively on the internet. Our mission is to profitably provide a
broad range of banking and financial services to the growing number of internet
users. Our low cost branchless business model allowed us to attain profitability
within a year of acquiring our bank charter and to continue to maintain
profitability while passing along our operating cost savings to customers in the
form of attractive interest rates and low fees. We strive to maintain high asset
quality by employing conservative credit policies. We plan to attract new
accounts through national awareness of the Net.B@nk brand name and to capitalize
on increasing consumer use of the internet.
 
    During 1998, our customer accounts grew from 4,755 to 17,408, deposits grew
from $58.7 million to $283.6 million and total assets grew from $93.2 million to
$388.4 million. During 1998, we added an average of 1,054 net customer accounts
per month. At March 31, 1999, we had 24,634 customer accounts, $332.7 million in
deposits and $526.5 million in total assets. During the four months ended April
30, 1999, we added an average of over 2,900 net customer accounts per month with
4,865 added in April alone. We believe our growth is attributable to our
expanded marketing program, increasing consumer use of the internet and our
ability to offer a broad array of convenient, cost-effective, secure banking
services to this growing customer base.
 
    The following charts demonstrate the growth in our total customer accounts,
checking accounts, deposits and assets:

    Since our equity offering in February 1999, we have continued to experience
rapid growth in our business and have entered into several new programs to
expand and improve our operational and product capabilities. Since February
1999, we have initiated the following:
 
    - EXPANDED MARKETING PROGRAM. We embarked on a new marketing program that
      has been highly successful in reaching our targeted audience and has
      resulted in a significant increase in checking accounts. We believe this
      growth in our checking account base indicates growing customer willingness
      to move their everyday banking activities to Net.B@nk and will result in
      long-term customer relationships. Furthermore, we believe that our
      checking account customers
 
                                       39
<PAGE>
      will visit our Web site more frequently and spend more time on our Web
      site, allowing us to cross-sell a variety of other products and services.
 
   
    - SERVICING AGREEMENT WITH PNC BANK CORP. We entered into a consumer loan
      processing and servicing agreement with PNC Bank Corp. This agreement will
      allow us to offer consumer loan products on-line. PNC will provide
      origination and loan servicing for these consumer loans as well as
      substantially all consumer loans for which we retain servicing rights on a
      scalable basis and at a favorable cost.
    
 
    - IMPROVED CUSTOMER SERVICE. We increased our customer support staff by over
      70% in order to maintain high-quality customer service. We have also
      invested in advanced technology and implemented new procedures in order to
      continually improve the quality and responsiveness of our customer
      service.
 
    - STRENGTHENED LENDING AND FINANCIAL OPERATIONS. We expanded our mortgage
      lending capabilities through a mortgage loan origination partnership with
      Virtuallender.com. We strengthened our lending and financial operations by
      adding several individuals to our professional staff. Additionally, we
      have significantly increased our loan portfolio while continuing to
      maintain a conservative lending and investment strategy.
 
INDUSTRY BACKGROUND
 
    THE INTERNET.  The internet enables millions of people worldwide to access
news and information, communicate with each other and conduct business
electronically. According to International Data Corporation, the number of
worldwide internet users is projected to grow from an estimated 159.3 million in
1998 to an estimated 410.4 million by 2002. Additionally, Jupiter Communications
estimates that 37.6 million United States households were on-line in 1998 and
that an estimated 62.6 million households are expected to be on-line in 2002.
On-line households are those that have access to the Web, use a consumer on-line
service or send e-mail.
 
    The internet has become a significant marketplace for buying and selling
goods and services. International Data Corporation forecasts that total
worldwide commerce on the internet will grow from an estimated $50.4 billion in
1998 to an estimated $733.6 billion in 2002. With the emergence of the internet
as a globally accessible, fully interactive medium, many companies that have
traditionally conducted business in person, through the mail or over the
telephone are increasingly conducting business electronically. Many consumers
are showing strong preferences for transacting certain types of business, such
as paying bills, booking airline tickets, trading securities and purchasing
consumer products, electronically rather than in person or over the telephone.
Individuals can now conduct these transactions virtually anywhere at any time.
Many consumers have embraced self-directed on-line transactions because such
transactions can be faster, less expensive and more convenient than transactions
conducted through a teller or an ATM.
 
    In addition to its use as a general commercial medium, the internet has
rapidly emerged as an innovative means of providing financial services. As
finance-related Web sites continue to grow in popularity, many companies are
increasingly offering a variety of financial services, including credit cards,
brokerage services, insurance products and banking services, via the internet.
 
    ELECTRONIC BANKING.  The growth in internet commerce has prompted the
development of electronic banking delivery systems. These forms of electronic
delivery systems provide convenience for customers and allow financial
institutions to lower their overhead costs. The two types of electronic banking
currently available, PC-based home banking and internet banking, are very
different. The characteristics of each are as follows:
 
    - PC-BASED HOME BANKING. PC-based home banking requires PC-based financial
      services software products such as Intuit's QUICKEN, Microsoft's MONEY or
      a bank's proprietary software. Each
 
                                       40
<PAGE>
      product carries its own set of instructions that the customer must learn
      before commencing any banking transactions. The software resides on the
      customer's PC along with his or her account data and requires a dial-up
      modem and manual downloading. Consequently, customers must conduct
      PC-based home banking from the PC containing the customer's software and
      account data. Customers generally must back up their account data at
      frequent intervals to counteract the risk of losing data. Because the
      customer must connect with the financial institution via modem and
      download his or her account data, real-time transactions are not generally
      possible.
 
    - INTERNET BANKING. Unlike PC-based home banking, internet banking requires
      only a secure Web browser for access to the internet and the financial
      institution. Internet banking requires no particular software and does not
      restrict the customer's operations to the location of his or her PC.
      Instead, the customer accesses the financial institution through the
      internet and deposits or transfers funds, pays bills or transacts other
      business on a real-time basis. In contrast, account data remains stored on
      Net.B@nk's secure server at all times, protected by technology designed
      specifically to safeguard such information. No downloading or back-up is
      required, as our server backs up all data and transactions on a continuous
      basis. With internet banking, the information presented to the customer
      remains current at all times.
 
    The use of electronic banking delivery systems, and particularly internet
banking, is growing as consumers find that electronic banking is both convenient
and cost-effective. According to Jupiter Communications, the number of on-line
banking households in the United States is projected to grow from an estimated
6.6 million in 1998 to an estimated 17.1 million in 2002.
 
    INTERNET DEMOGRAPHICS. Demographic surveys indicate that internet users
represent an ideal target market for internet banking. Recent studies by Jupiter
Communications revealed that, in the United States, approximately 47% of on-line
users are college graduates and that approximately 37% are engaged in
professional or managerial occupations. The survey also indicated that the
largest group on-line is adults aged 19 to 34, that approximately 86% of on-line
users are under the age of 50 and that 43% of the on-line audience earns over
$60,000 per year. The attractive demographics of internet users facilitate the
growth of internet banking. Internet users tend to be young and mobile and thus
more inclined to be comfortable with and receptive to the convenience of on-line
commercial transactions. We believe that as internet users enter their prime
earnings and savings years, there will be an increased demand for high-yielding
savings products. Additionally, internet users tend to be professionals with
limited amounts of discretionary time and are attracted to the convenience of
"one-stop shopping" for a full range of financial services.
 
THE NET.B@NK SOLUTION
 
    As the first federally-insured bank to operate solely on the internet, we
believe we have a first mover advantage relative to on-line banks with less
extensive market presence and less established operating histories. In addition,
we have a competitive cost advantage over traditional banks. We also believe our
established position in the marketplace provides us with a competitive advantage
in view of the lead time required for new competitors to obtain a charter and
start an internet bank. We intend to continue to capitalize on this advantage by
aggressively seeking new customers in order to further build market share.
 
    Our customer demographics parallel those of the general internet population
and illustrate Net.B@nk's appeal to households with relatively high incomes.
According to John H. Harland Company, as of September 1998, our customers had an
average age of 44 and a median annual household income in excess of $50,000. We
are ideally positioned to participate in the rapid growth of the internet and
on-line banking based on our:
 
    - ATTRACTIVE INTEREST RATES AND LOW FEES. Our operating costs are generally
      lower than those of traditional "bricks and mortar" banks because we do
      not require a traditional branch network to
 
                                       41
<PAGE>
      generate deposits and conduct operations. We pass our savings in operating
      costs on to customers by offering attractive interest rates and low fees
      in order to generate deposits without sacrificing profit margins. We
      believe our unique business model differentiates Net.B@nk from traditional
      banks offering internet banking services because traditional banks
      frequently offset the incremental expense of their internet banking
      services by charging additional fees or imposing minimum account balances.
 
    - CONVENIENCE AND EASE OF ACCESS. We believe we provide customers with a
      higher level of convenience than can be achieved in a traditional bank
      branch or through PC-based home banking. The internet allows our customers
      to conduct banking activities on a real-time, 7-day-a-week, 24-hour-a-day
      basis from any PC, wherever located, using a secure Web browser. In
      addition, our Web site is designed to be user-friendly and to expedite
      customer transactions with Net.B@nk.
 
    - BROAD SELECTION OF PRODUCTS AND SERVICES. We offer a broad array of
      products and services that customers would typically expect from a
      traditional bank. These products and services include checking and money
      market accounts, certificates of deposit, electronic bill payment, debit
      cards, credit cards, mortgage loans, business equipment leases and
      securities brokerage services. We plan to offer consumer loans, including
      home equity and automobile loans, beginning in the third quarter of 1999.
      We intend to continue to develop additional products and services such as
      insurance products, electronic bill presentment and electronic document
      and image storage in a virtual safe deposit box.
 
    - HIGH-QUALITY SERVICE AND CUSTOMER SATISFACTION. We continually seek ways
      to enhance customer satisfaction. In an effort to serve the needs of our
      customers, we offer services such as electronic bill payment and ATM cards
      without service charges. We also emphasize responsive, courteous customer
      service and utilize a fully-trained dedicated staff who respond to
      inquiries from existing and potential customers and process new accounts.
      Our customers can access account data and information regarding products
      and services 24 hours a day and can currently reach our customer service
      representatives by telephone or e-mail. We strive for the highest level of
      customer satisfaction and believe the significant growth in our customer
      base illustrates our ability to meet our customers' needs.
 
    - ADVANCED SECURITY. A significant barrier to on-line financial transactions
      has been the secure transmission of confidential information over public
      networks. We use sophisticated technology to provide what we believe to be
      among the most advanced security measures currently available in the
      internet banking industry. All banking transactions are encrypted and all
      transactions are routed from the internet server through a "firewall" that
      limits access to the Net.B@nk server. Our systems automatically detect
      attempts by third parties to access other users' accounts and feature a
      high degree of physical security, secure modem access, service continuity
      and transaction monitoring. See "--Security."
 
GROWTH STRATEGY
 
    Our objective is to become the leading provider of a full range of on-line
financial services. We intend to accomplish this objective by implementing the
following strategies:
 
    - BUILD NATIONAL BRAND AWARENESS THROUGH INCREASED MARKETING EFFORTS. We
      have significantly expanded our marketing program and are working with
      nationally known advertising and public relations agencies to build
      national awareness of the Net.B@nk name through a variety of marketing
      initiatives. These initiatives include expanding our advertising media to
      include print and direct mail campaigns; continued advertisement on
      targeted portals such as Yahoo!, Alta Vista, Infoseek, Lycos, AOL and
      Excite and Web sites such as Bank Rate Monitor, iVillage and Motley Fool;
      and the pursuit of strategic alliances with other internet financial
      service providers.
 
                                       42
<PAGE>
      To fund these initiatives, we have increased our marketing expenditures
      from approximately $695,000 for 1998 to a budgeted $6.6 million for 1999.
      During the first quarter of 1999, we applied approximately $400,000 to our
      marketing program and added 7,226 new accounts. We plan to increase our
      print and on-line advertising and continue to explore opportunities in
      broadcast advertising during the course of the year. Our experience
      indicates that by expanding our marketing efforts further, we can heighten
      brand awareness of Net.B@nk on a national scale and significantly increase
      our customer base. See "--Marketing."
 
    - LEVERAGE LOW COST STRUCTURE. Our operating costs are generally lower than
      those of traditional "bricks and mortar" banks because we do not require a
      traditional branch network to generate deposits and conduct operations.
      This is demonstrated by our low ratio of annualized fourth quarter 1998
      noninterest expenses to average earning assets of 1.7% compared to 4.2%
      for commercial banks with $300 million to $500 million in assets, as
      calculated by the FDIC Institution Directory by multiplying the
      noninterest expenses for the quarter divided by the average earning assets
      for the quarter by four. Additionally, our ratio of total assets per
      full-time equivalent employee was $13.9 million as of December 31, 1998
      compared to $2.6 million for commercial banks with $300 million to $500
      million in assets, based on data provided by the FDIC Institution
      directory. We pass our operating cost savings on to customers by offering
      more attractive interest rates on deposit accounts and lower fees than
      those offered generally by traditional banks. We believe this strategy
      attracts deposits without sacrificing profit margins. We intend to
      continue to leverage the fixed-cost aspect of our branchless business
      model to enhance profitability.
 
    - OFFER A BROAD ARRAY OF PRODUCTS AND SERVICES. Our objective is to attract
      customers seeking to combine the convenience of internet banking with the
      broad array of products and services typically offered by traditional
      banks. Toward this end, our product and service offerings include checking
      and money market accounts, certificates of deposit, electronic bill
      payment, debit cards, credit cards, mortgage loans, business equipment
      leases and securities brokerage services. We plan to offer consumer loans,
      including home equity and automobile loans, beginning in the third quarter
      of 1999. We also intend to continue to develop additional products and
      services such as insurance products, electronic bill presentment and
      electronic document and image storage in a virtual safe deposit box. See
      "--Products and Services."
 
    - MAINTAIN HIGH ASSET QUALITY. Our loan portfolio strategy is to maintain a
      conservative loan mix consisting of home mortgage, home equity, consumer,
      commercial and construction loans with an emphasis on high credit quality.
      At our current stage of development, it is more cost-effective for us to
      purchase most of our loans or act as a participating lender with other
      banks rather than originate our own loans. This strategy decreases our
      expenses and allows us to reduce our loan loss exposure by diversifying
      our portfolio. We also emphasize a conservative securities investment
      strategy by investing in fixed income securities such as United States
      Treasury obligations, collateralized mortgage obligations and
      mortgage-backed securities issued by agencies such as Federal National
      Mortgage Association and Federal Home Loan Mortgage Corporation. See
      "--Lending and Investment Activities."
 
    - OUTSOURCE OPERATIONAL FUNCTIONS. To enhance the flexibility and
      scalability of our operations, we outsource certain principal operational
      functions to leading service providers such as NCR, BISYS and CheckFree.
      NCR provides a secure server for the electronic banking software licensed
      to us by Edify Corporation. CheckFree provides electronic bill payment
      systems for us and BISYS processes our transactions and interfaces with
      NCR's secure server. In each of these relationships, we benefit from the
      service provider's expertise and economies of scale while retaining the
      flexibility to take advantage of changes in available technology without
      affecting customer service. We can also respond easily to growth because
      these third-party service
 
                                       43
<PAGE>
      providers have the capacity to process a high volume of transactions. See
      "--Operations-- Service Providers."
 
    - GENERATE NONINTEREST INCOME THROUGH CROSS-MARKETING INITIATIVES. To
      generate additional noninterest income and enhance customer loyalty, we
      cross-market a variety of non-deposit products. We offer credit cards,
      mortgage loans, business equipment leases, securities brokerage services
      and other noninterest income-generating products. We offer these products
      to existing and potential depositors through various marketing techniques,
      such as our Web site, e-mail, on-line advertising and direct mailings.
      This strategy enables us to generate additional earning assets and fee
      income from a growing customer base.
 
PRODUCTS AND SERVICES
 
    DEPOSIT PRODUCTS AND SERVICES.  In order to build our customer base, we
offer a variety of deposit products at attractive interest rates. We are able to
offer attractive interest rates as a result of our low operating costs. We also
attract customers by offering convenient services such as free electronic bill
payment, overdraft protection and ATM cards. Our deposit products and services
include:
 
    - DEPOSIT PRODUCTS. We offer two types of interest-bearing checking
      accounts, a money market account and 6-, 12- and 30-month certificates of
      deposit. We have consistently offered interest rates on our deposit
      accounts that are higher than the national average.
 
    - BILL PAYMENT SERVICE. Through services provided by CheckFree, customers
      can pay their bills on-line through electronic funds transfer or a written
      draft prepared and sent to the creditor. We do not charge a fee for this
      service.
 
    - OVERDRAFT PROTECTION. Overdraft protection is available to all interest
      checking customers who qualify. Customers with interest checking accounts
      may apply for overdraft protection on-line for amounts up to $5,000. If a
      customer has both a money market and an interest checking account, we
      automatically establish overdraft protection between those accounts.
 
    - ATM CARDS. Each customer automatically receives a free ATM card when he or
      she opens an account. Customers can access their accounts at ATMs
      affiliated with the Cirrus, Honor and Avail networks. We do not charge our
      own fee for ATM usage, but the operator of the ATM generally imposes fees.
 
    LENDING PROGRAMS.  To generate fee income and provide a convenient service
to our customers, we offer on-line loans and credit cards as described below.
 
    - MORTGAGE LOANS. Our Web site enables customers to obtain interest rate
      quotes and apply for mortgage loans on-line. We have an agreement with
      mortgage.com (formerly known as First Mortgage Network), under which we
      act as a loan originator on their behalf. We have similar agreements with
      E-loan, Inc., Virtuallender.com and Fidelity Mortgage Services, Inc. under
      which they forward mortgage applications to us. Applications received
      directly through our Web site are processed and closed by mortgage.com.
      Applications received indirectly from mortgage.com, E-loan,
      Virtuallender.com or Fidelity Mortgage Services are processed by the
      respective lender, which in turn receives funding from us and closes the
      loans. We fund each loan that meets our underwriting criteria and sell the
      loans received directly through our Web site to mortgage.com or, in the
      case of loans received indirectly, to the lender from which it was
      received, in each case with the servicing rights released. The loans are
      presold to the same sources at the time of closing so that we do not bear
      any material risk of loss. We generally carry loans receivable on our
      books for an average of approximately 30 days while we await receipt of
      sale proceeds. During this time, we receive interest income on the
      outstanding balance at the rate stated in the mortgage note. We also
      receive a portion of the loan origination fee for providing these funding
      services. We plan to expand our loan offerings to include home equity
 
                                       44
<PAGE>
      loans, home equity lines of credit and automobile loans. We also originate
      and retain a small number of home mortgage loans for our own portfolio.
      See "--Lending and Investment Activities."
 
    - CREDIT CARDS. We offer our customers Visa and MasterCard credit cards
      issued by The Bankers Bank for no annual fee. The Bankers Bank carries the
      credit card loans on its books and we have an income-sharing arrangement
      with The Bankers Bank. Customers can apply for these credit cards on-line.
      The cards prominently display the Net.B@nk logo with the Visa or
      MasterCard emblem appearing in the lower right corner of the card.
 
    NON-BANKING FINANCIAL SERVICES.  To serve as a sole source for the financial
services needs of internet users and to generate additional noninterest income,
we offer a full range of non-banking financial services designed to attract and
retain customers. These services currently include securities brokerage and
business equipment leasing services and in the future will include several new
services such as insurance products.
 
    - SECURITIES BROKERAGE SERVICES. We have contracted with UVEST Investment
      Services, a discount broker, to provide our customers with access to a
      full line of financial services and investment products. We have a
      fee-sharing agreement with UVEST Investment Services. Customers can
      purchase securities without writing checks to their brokers, as trading
      fees are automatically deducted from their Net.B@nk checking or money
      market accounts. Investment proceeds are automatically deposited into the
      customer's Net.B@nk deposit account. Customers enjoy 24-hour on-line
      access, real-time quotes, low commissions and a professional brokerage
      staff.
 
    - BUSINESS EQUIPMENT LEASING. In October 1998, we entered into an agreement
      with Republic Leasing Company that allows our customers, many of whom are
      independent business owners or managers, to lease small business equipment
      through Republic Leasing. We have a fee-sharing agreement with Republic
      Leasing. Lease amounts range from $5,000 to $500,000 and cover virtually
      all types of business equipment. Republic Leasing provides advice,
      comparison quotes and immediate equipment lease financing and holds and
      services all of its leases.
 
    FUTURE PRODUCTS AND SERVICES.  To generate additional interest and fee
income and enhance customer convenience, Net.B@nk plans to introduce a variety
of new products and services. We plan to offer consumer loans, including home
equity and automobile loans, beginning in the third quarter of 1999. Other
future products and services may include insurance products, electronic bill
presentment and electronic document and image storage in a virtual safe deposit
box.
 
LENDING AND INVESTMENT ACTIVITIES
 
    Our loan portfolio strategy is to maintain a conservative loan mix
consisting of home mortgage, home equity, consumer and construction loans with
an emphasis on high credit quality. At our current stage of development, it is
more cost-effective for us to purchase most of our loans or act as a
participating lender with other banks rather than originating our own loans.
This strategy decreases our expenses and allows us to diversify our portfolio.
As we grow, we will continue to develop our portfolio through purchases,
participations and direct originations.
 
    We build our loan portfolio in the following ways:
 
    - PURCHASES. We acquire most of our loans by purchasing packages of specific
      types of loans, such as mortgage, home equity and consumer loans, with
      each package consisting of loans with similar principal amounts, interest
      rates and asset quality. We also purchase portions of commercial loan
      pools, with the seller retaining a portion of the loans to decrease our
      risk. As of March 31, 1999, purchased loans accounted for approximately
      $259.6 million, or 71.3%, of our loan portfolio.
 
                                       45
<PAGE>
    - PARTICIPATIONS. We act as a participating lender in commercial and large
      construction loans with varying banks in the Southeast, including The
      Bankers Bank. We anticipate expanding our participations in construction
      loans to include loans originated nationwide in order to take advantage of
      lower prices for these loans in less competitive geographic areas. As of
      March 31, 1999, participations accounted for approximately $81.2 million,
      or 22.3%, of our loan portfolio.
 
    - DIRECT ORIGINATION. We originate a small number of loans directly with our
      customers. As of March 31, 1999, these loans accounted for approximately
      $23.3 million, or 6.4%, of our loan portfolio.
 
    In addition, as described in "--Products and Services," "-- Lending
Programs" and "--Mortgage Loans," we have agreements with each of mortgage.com,
E-loan, Virtuallender.com, BancMortgage and Fidelity Mortgage Services that
provide that we act as a loan originator on their behalf. From May 1998, when we
began providing services under the first of these agreements, to March 31, 1999,
we funded $258.2 million of loans for third parties. As of March 31, 1999, we
had $35.0 million in loan sale proceeds receivable relating to these agreements.
In the future, we may retain a portion of such loans for our own portfolio.
 
    Our loan committee establishes underwriting standards and criteria for our
loan portfolio and monitors the portfolio on an ongoing basis. The loan
committee applies the same underwriting standards to all of our loans,
regardless of how they are originated. We have also retained an outside
consulting firm to assist the loan committee in its review of the loan portfolio
and to conduct due diligence on purchased loans.
 
    In addition to loans, we invest deposit funds in various fixed income
securities. Our philosophy of high credit quality also guides our investment
decisions. Our fixed income securities portfolio is comprised primarily of
United States Treasury obligations, collateralized mortgage obligations and
mortgage-backed securities issued by agencies such as Federal National Mortgage
Association and Federal Home Loan Mortgage Corporation.
 
CUSTOMER SATISFACTION
 
    We continually seek ways to enhance customer satisfaction. Offering our
customers a high-level of customer service is a top priority of ours and we
believe that it is critical to our success. In an effort to serve the needs of
our customers, we offer services such as electronic bill payment and ATM cards
without service charges. Our customers can access account data and information
regarding products and services 24 hours a day and can currently reach our
customer service representatives by telephone and e-mail.
 
    We are committed to investing in customer service. We recently created a
managerial position dedicated to customer service and hired an individual with
approximately 20 years of experience in customer service and call center
management. We have also expanded our customer support staff by over 70% in
order to maintain high-quality customer service. We have also invested in
technology and implemented new procedures in order to continually improve the
quality and responsiveness of our customer service. To optimize our customer
service resources, we have designed a user-friendly Web site with a goal of
achieving customer self-support. For example, customers can find answers to
their "frequently asked questions" and intuitively navigate our Web site.
 
                                       46
<PAGE>
MARKETING
 
    The goal of our marketing strategy is to make Net.B@nk the leading brand in
the internet financial services market. Our marketing strategy is designed to
grow our customer base and includes targeted advertising on the internet and
other media, developing strategic partnerships that will enhance our product and
service offerings, cross-marketing initiatives to existing customers and
fostering public relations. Our marketing campaign launched after our February
1999 offering has been highly successful, and we plan to significantly increase
our marketing expenses from $695,000 in 1998 to a budgeted $6.6 million for
1999.
 
    During the first quarter of 1999, we applied approximately $400,000 to our
marketing program and added 7,226 new accounts. We plan to increase our print
and on-line advertising and continue to explore opportunities in broadcast
advertising during the course of the year. We have recently hired additional
marketing support staff and believe that a significant increase in our marketing
initiatives will enable us to increase our name recognition and grow our
customer and deposit base on a national scale.
 
    ADVERTISING STRATEGIES.  We have allocated the majority of our advertising
budget to on-line advertising because we believe it is a rapidly growing medium
that best reaches our target audience. We currently market our products and
services by placing banner ads on portals such as Yahoo!, Alta Vista, Infoseek,
Lycos, AOL and Excite and Web sites such as Bank Rate Monitor, iVillage and
Motley Fool that our experience indicates will attract our target customers. We
have enhanced our ability to monitor the audience that we reach as well as the
results of our on-line advertising campaign. For example, we track the number of
hits on our Web site that result from a particular advertisement and incorporate
our findings into our subsequent marketing efforts.
 
    We also utilize traditional advertisement media. We have a national print
media campaign aimed at increasing brand awareness. Our print media campaign has
included a series of advertisements in national newspaper and magazines such as
THE WALL STREET JOURNAL, FORBES, PC WORLD, and INTERNET LIFE. We added direct
mail marketing to our marketing activities and we are evaluating opportunities
in broadcast advertising.
 
    STRATEGIC PARTNERSHIPS.  We continually seek to form product and marketing
alliances with other internet financial services providers such as
Virtuallender.com and E-loan to broaden our product and service offerings and
attract a broader customer base. We plan to pursue other marketing alliances
such as co-branded credit cards. We believe these alliances provide us with the
opportunity to cross-market our products and services to the customers of these
financial service providers and to our existing customers.
 
    PUBLIC RELATIONS.  We also derive a marketing benefit from media coverage
that we generate through our public relations campaign. We believe this coverage
increases the general public's awareness of Net.B@nk and attracts new customers.
 
COMPETITION
 
    We believe that the principal competitive factors in the banking industry
are market presence, customer service, convenience, product offerings and
deposit and loan rates and associated account fees. While the banking industry
is highly competitive, we believe we compete effectively with our principal
competitors, which are traditional banks, internet banks and other financial
services providers. We believe our low cost structure, which allows us to offer
attractive interest rates and low fees, gives us a competitive advantage over
traditional banks, which must support a physical branch structure. We also
believe our operating history and name recognition give us an advantage over
other independent internet banks, most of which are still in a relatively early
stage of operation. Furthermore, we are able to offer a broader array of
products and services than many non-bank financial services providers. However,
many of our competitors have larger customer bases, greater name recognition and
brand awareness, greater financial and other resources and longer operating
histories. Additionally, new
 
                                       47
<PAGE>
competitors and competitive factors are likely to emerge, particularly in view
of the rapid development of internet commerce. See "Risk Factors--Industry
competition may adversely affect our success."
 
OPERATIONS
 
    ACCOUNT ACTIVITY.  Customers can access Net.B@nk through any internet
service provider by means of an acceptable secure Web browser. In doing so,
customers can apply for loans, review account activity, enter transactions into
an on-line account register, pay bills electronically, conduct brokerage
transactions, receive statements by mail and print bank statement reports from
any PC with a secure Web browser, regardless of its location. To open a new
account, the customer completes the on-line enrollment form on our Web site,
prints the signature card, signs it and mails it to us. Customers can make
deposits into an open account at Net.B@nk via direct deposit programs, by
transferring funds between Net.B@nk accounts, by wire transfer, by mail or in
person at our principal executive offices. No teller line is maintained,
however, and we do not have or intend to establish a physical branch system.
Customers can also make withdrawals and have access to their accounts at ATMs
that are affiliated with the Cirrus, Honor and Avail networks, which provides
added customer convenience.
 
    SERVICE PROVIDERS.  We have negotiated relationships with a select group of
service providers who not only provide us with significant quality, security,
reliability, performance and marketing capabilities, but also play an integral
role in implementing our full financial services strategy. Because we outsource
our principal operational functions to experienced third-party service providers
that have the capacity to process a high volume of transactions, we can respond
easily to growth. Moreover, we have preserved a degree of flexibility that
enables us to assess and evaluate our product offerings and delivery structure
on an ongoing basis and to incorporate other alliance opportunities as they
present themselves. Should any of these relationships terminate, however, we
believe we could secure the required services from an alternative source without
material interruption of our operations. Our principal service providers are
described below:
 
    - NCR. NCR provides operational support for our internet banking and bill
      payment applications. Specifically, NCR provides a secure Web site,
      software that performs services relating to our infrastructure and other
      electronic banking services. NCR also hosts Edify's electronic banking
      software on its secure server and provides the interface necessary to link
      our servers with those used by BISYS and CheckFree.
 
    - BISYS. We receive core systems processing services, such as deposit
      account, loan and year-end processing services, from BISYS. The BISYS
      server interfaces with NCR's secure server and verifies customer passwords
      and identification. BISYS also operates our ATM and debit card systems.
 
    - EDIFY. Edify licenses its Electronic Banking System and Electronic
      Workforce software, a suite of internet banking applications, to us. Edify
      also maintains the software and provides consulting services as needed.
 
    - CHECKFREE. CheckFree provides electronic bill paying services to our
      customers. Customers can pay their bills on-line through electronic funds
      transfer or a written draft prepared and sent to the creditor.
 
    - UVEST INVESTMENT SERVICES. UVEST Investment Services provides discount
      brokerage services to our customers. UVEST Investment Services executes
      the trades and receives a commission that is automatically deducted from
      our customer's deposit account.
 
    - MORTGAGE.COM. mortgage.com processes mortgage loan applications submitted
      through our Web site. It reviews the application, contacts the customer
      and closes the loan for us.
 
    - PNC BANK CORP. We plan to offer consumer loans, including home equity and
      automobile loans, in the third quarter of 1999. PNC will originate and
      service these loans and will service other consumer loans on a servicing
      released basis.
 
                                       48
<PAGE>
    As part of our outsourcing strategy, we will continue to explore the
outsourcing of a variety of our operations, including customer service, new
product offerings and certain lending and portfolio management activities.
 
SECURITY
 
    Our ability to provide our customers with secure financial services over the
internet is of paramount importance. We continually evaluate the internet
systems, services and software used in our operations to ensure that they meet
the highest standards of security. The following are among the security measures
that are in place:
 
    ENCRYPTED TRANSACTIONS.  All banking transactions and internet
communications are encrypted so that sensitive information is not transmitted
over the internet in a form that can be read or easily deciphered. Encryption of
internet communications is accomplished through the use of the Netscape Secure
Sockets Layer technology. This technology is the standard for encryption on the
internet and is currently used by Netscape's NAVIGATOR (Version 2.0 or higher)
and Microsoft's INTERNET EXPLORER (Version 3.0 or higher). Messages between our
server and BISYS are encrypted using DES encryption, which is described in
"--Isolated Bank Server" below.
 
    SECURE LOGON.  To eliminate the possibility that a third party may download
Net.B@nk's or a customer's password file, user identification and passwords are
not stored on the internet or the Web server. Furthermore, passwords are strings
of six to eight alpha-numeric characters, which makes the chance that a password
can be randomly guessed less than one in one trillion.
 
    ISOLATED BANK SERVER.  The computer used to provide our services cannot be
accessed directly through the internet. It is on a private connection, or
intranet, that provides two-way communication between the isolated bank server
and the NCR internet server. Consequently, an internet user cannot directly
access the computer that actually provides our services.
 
    All banking services are routed from the NCR server through a firewall. The
firewall is a combined software and hardware product that precisely defines,
controls and limits the access to "internal" computers from "outside" computers
across a network. Use of this firewall means that only authenticated bank
customers or administrators may send or receive transactions through it, and the
firewall itself is immune to penetration from the network. In other words, the
firewall is a mechanism used to protect our server from the freely accessible
internet.
 
    Furthermore, all messages sent or received between the NCR server and our
server are encrypted using DES encryption. This is a symmetric key algorithm and
is highly secure because it is not susceptible to standard ciphertext attacks.
Thus, even if a perpetrator were able to route a message to our server through
the firewall, the message could not be encrypted in a way that would be
considered valid by the server. As a result, our server would reject the
message.
 
    AUTHENTICATED SESSION INTEGRITY.  An authenticated user is any user who
signs onto our Web site with a valid user ID and password. Although the vast
majority of authenticated users are legitimate bank customers, our server is
programmed to limit exposure to an authenticated user who is attempting to
defraud Net.B@nk. If the authenticated user alters the URL, which is the command
or request that is sent from the browser to the server, in any way in an attempt
to gain access to other users' accounts, our server immediately detects that the
session integrity variables have been violated. Our server will immediately stop
the session and record the attempt in a log so that our staff can investigate.
 
    PHYSICAL SECURITY.  All servers and network computers reside in secure NCR
facilities. Currently, computer operations supporting our internet access are
based in Columbia, Maryland with backup facilities in Dayton, Ohio. Only
employees with proper photographic identification may enter the primary
building. The computer operations are located in a secure area, with admission
only by key card. Access to our server console requires further password
identification.
 
                                       49
<PAGE>
    SECURE MODEM ACCESS. A private line that is not accessible from the public
network connects our server and BISYS. Our server is connected to CheckFree by a
similar private connection. A dial-up maintenance port also permits access to
our server. The modem that provides the only access to this port is specially
protected and is only enabled on an as-needed basis.
 
    SERVICE CONTINUITY.  NCR and BISYS each provide a fully redundant network
with no single point of failure. Our server is also "mirrored" so that hardware
failures or software bugs should cause no more than a few minutes of service
outage. "Mirroring" means that our server is backed up continuously so that all
data is stored in two physical locations. This network and server redundancy
ensures that access to Net.B@nk will be reliable. However, if customers are not
able to access Net.B@nk over the internet, customers retain access to their
funds through several means, including paper checks, ATM cards, customer service
and an automated telephone response system.
 
    MONITORING.  All customer transactions on our server using services provided
by BISYS and CheckFree produce one or more entries into transactional logs. We
and NCR recognize that it is critical to monitor these logs for unusual or
fraudulent activity. As mentioned previously, any attempt by an authenticated
user to modify the command or request that is sent from the browser to the
server is logged. Additionally, all financial transactions are logged. Bank
personnel review these logs regularly, and we or NCR will note any abnormal or
unusual activity and take appropriate action. Ultimately, vigilant monitoring is
the best defense against fraud.
 
    The preceding security measures are designed to ensure that Net.B@nk is set
up in a secure manner. However, over the long term, our security depends upon
the procedures and standards used for administration of the internet site. Both
NCR and BISYS are required to obtain SAS 70 certification from a national
accounting firm. This is a certification by independent auditors that the NCR
and BISYS computer systems are being managed and operated in a manner consistent
with accepted practices. Both BISYS and NCR have received this certification.
 
    We believe the risk of fraud presented by internet banking is not materially
different from the risk of fraud inherent in any banking relationship. We
believe the three principal reasons for a breach in bank security are:
 
    - Misappropriation from the user of the user's account number or password;
 
    - Penetration of our server by an outside "hacker"; and
 
    - Fraud committed by one of our employees or an employee of one of our
      service providers.
 
Both traditional banks and internet banks are vulnerable to these types of
fraud. By establishing the security measures described above, we believe we have
reduced our vulnerability to the first two types of fraud. To counteract fraud
by employees, associates and consultants, we have established internal
procedures and policies designed to ensure that, as in any bank, proper control
and supervision is exercised over employees, associates and consultants. We also
counteract all types of fraud through daily examination of our transactional
logs.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
    We regard the form and substance of our name and other intellectual property
we have developed as proprietary and attempt to protect them by relying on
intellectual property laws. We have submitted a United States trademark
registration for the Net.B@nk name and take active measures to safeguard our
name and other proprietary intellectual property. Policing unauthorized use of
proprietary information is difficult, however, and litigation may be necessary
to enforce our intellectual property rights.
 
    We own the internet domain name "netbank.com." Domain names in the United

SUPERVISION AND REGULATION
 
    References to "we," "us," "our" and "Net.B@nk" generally refer to Net.B@nk,
Inc. and its sole subsidiary, Net.B@nk, on a consolidated basis, except where we
indicate that Net.B@nk, Inc. means only the parent entity and Net.B@nk refers
only to the banking subsidiary.
 
    BACKGROUND.  In connection with its approval of the July 31, 1997
acquisition of our bank charter, the Office of Thrift Supervision required us to
make certain commitments with respect to our ongoing operations. These
commitments included:
 
    - Until July 28, 2000, receiving prior approval from the Office of Thrift
      Supervision before making any changes to our senior management team or
      board of directors;
 
    - Operating within the parameters of our business plan as submitted to the
      Office of Thrift Supervision;
 
    - Obtaining from an independent computer security specialist an independent
      review of, and written report regarding, the internet banking security
      measures we employ;
 
    - Complying with the Office of Thrift Supervision policy statement regarding
      on-line banking;
 
    - Ensuring that our directors and certain executive officers and
      shareholders refrain from disposing of their restricted shares of common
      stock without the prior consent of the Office of Thrift Supervision until
      July 28, 2000;
 
    - Obtaining the approval of the Regional Director of the Office of Thrift
      Supervision with respect to any changes in our stock benefit plans
      effected on or before July 28, 2000;
 
    - Complying with Office of Thrift Supervision directives, if any, that
      require the exercise or forfeiture of participants' rights under our stock
      benefit plans in the event our capital falls below minimum Office of
      Thrift Supervision requirements; and
 
    - Submitting to the Office of Thrift Supervision a structured project plan
      describing the steps and timing required to replace the Web hosting
      services that were previously provided by AT&T Corp. and are now provided
      by NCR.
 
    We and our directors, executive officers and shareholders have complied with
these conditions to date.
 
    On January 8, 1999, the Office of Thrift Supervision granted Carolina First
Corporation permission to sell a portion of its shares of common stock in
Net.B@nk's February 1999 public offering. As a condition to its approval, the
Office of Thrift Supervision required that two of the four directors initially
nominated by Carolina First Corporation resign following completion of the
offering and that those directors be replaced with two outside directors within
six months of the resignations. The Office of Thrift Supervision also required
Carolina First Corporation to refrain from disposing of its remaining shares of
common stock without the prior consent of the Office of Thrift Supervision. We
do not believe that these commitments have or will materially affect our
operations.
 
    Carolina First Corporation currently owns more than five percent of our
outstanding common stock. As a result, Carolina First Corporation is subject to
certain Federal Reserve Board regulations regarding its relationship with
Net.B@nk. Until Carolina First Corporation owns less than five percent of our
outstanding common stock, we will not engage in any activities that are not
permissible under applicable Federal Reserve Board regulations.
 
    SAVINGS AND LOAN HOLDING COMPANY REGULATION.  Savings and loan holding
companies and federal savings banks are extensively regulated under both federal
and state law. The following is a brief summary of certain statutes, rules and
regulations that affect Net.B@nk, Inc. and its banking subsidiary. This summary
is qualified in its entirety by reference to the particular statutory and
 
                                       51
<PAGE>
regulatory provisions referred to below. This summary is not intended to be an
exhaustive description of the statutes or regulations applicable to our
business. Supervision, regulation and examination of Net.B@nk by regulatory
agencies is intended primarily for the protection of our depositors rather than
our shareholders. The terms bank, savings institution, savings association,
federal savings bank and thrift are used interchangeably in this section to
refer to savings associations such as Net.B@nk, Inc.'s banking subsidiary that
are subject to supervision and regulation by the Office of Thrift Supervision.
The terms savings and loan holding company and holding company are used
interchangeably to refer to holding companies, such as Net.B@nk, Inc., that are
subject to supervision and regulation by the Office of Thrift Supervision.
 
    Net.B@nk, Inc. is registered as a holding company under both the Savings and
Loan Holding Company Act set forth in Section 10 of the Home Owners Loan Act and
the Financial Institutions Code of Georgia. Net.B@nk, Inc. is currently
regulated under these acts by the Office of Thrift Supervision and by the
Georgia Department of Banking and Finance. As a savings and loan holding
company, Net.B@nk, Inc. is required to file with the Office of Thrift
Supervision an annual report and any additional information that the Office of
Thrift Supervision may require under the Savings and Loan Holding Company Act.
The Office of Thrift Supervision also conducts examinations of Net.B@nk, Inc.
and its banking subsidiary.
 
    Generally, savings and loan holding companies and their subsidiaries may not
engage in activities or render any services for or on behalf of their savings
institution subsidiaries for the purpose or with the effect of evading any law
or regulation applicable to the institution. This restriction is designed to
prevent savings and loan holding companies and their affiliates from evading
requirements of the Savings and Loan Holding Company Act that were enacted to
protect a holding company's savings institution subsidiaries. A unitary thrift
holding company, that is, a holding company that owns only one insured
institution whose subsidiary institution satisfies the qualified thrift lender
test (discussed below), however, is not restricted to any statutorily prescribed
list of permissible activities, and the Savings and Loan Holding Company Act and
the Financial Institutions Code of Georgia impose no limits on direct or
indirect non-savings institution subsidiary operations. Net.B@nk, Inc. is a
unitary thrift holding company and qualifies for this exception. However, as
discussed above, we have committed that Net.B@nk, Inc. will not engage in any
activity that is impermissible for bank holding companies under Federal Reserve
Board regulations.
 
    The Savings and Loan Holding Company Act and the Financial Institutions Code
of Georgia make it unlawful for any savings and loan holding company to acquire
control of another savings association or savings and loan holding company
without prior approval from the Office of Thrift Supervision and the Georgia
Department of Banking and Finance. These statutes also prohibit a savings
institution or holding company from merging with, consolidating with or
purchasing all or substantially all of the assets of another institution or
holding company without prior approval. The Office of Thrift Supervision and the
Georgia Department of Banking and Finance take into consideration the financial
and managerial resources and future prospects of the institutions involved when
considering an application for these transactions. This includes consideration
of the competence, experience and integrity of the officers, directors and
principal shareholders of the companies. In addition, the agencies consider the
effect of the transaction on the institution, the insurance risk to the Savings
Association Insurance Fund and the convenience and needs of the community to be
served.
 
    The Office of Thrift Supervision may not approve an acquisition that would
result in the formation of certain types of interstate banking networks. The
Office of Thrift Supervision is precluded from approving an acquisition that
would result in the formation of a holding company that controls savings
institutions in more than one state. If, however, the acquiring company or one
of its savings institution subsidiaries is authorized to acquire control of an
institution or to operate an office in the additional state under a supervisory
acquisition authorized under Section 13(k) of the Federal Deposit Insurance Act
or the statutes of the state in which the institution to be acquired is located
permits the acquisition, then the acquisition may be approved.
 
                                       52
<PAGE>
    Savings and loan holding companies are generally allowed to acquire or to
retain as much as 5% of the voting shares of a savings institution or savings
and loan holding company without regulatory approval.
 
SAVINGS BANK REGULATION
 
    GENERAL.  Net.B@nk is chartered by the Office of Thrift Supervision, a
bureau of the United States Treasury, and is subject to examination by the
Office of Thrift Supervision and the FDIC. The Office of Thrift Supervision
regulates all areas of our banking operations including reserves, lending,
mergers, payment of dividends, interest rates, establishment of branches and
other aspects of our operations. Federal savings banks with assets greater than
or equal to $250 million, like Net.B@nk, must be examined no less frequently
than every 12 months. Federal savings banks with assets less than $250 million
may be examined no less frequently than 18 months, if they are well capitalized
and meet other regulatory requirements. Additionally, the Office of Thrift
Supervision may assess the federal savings bank with the cost of the
examination.
 
    The FDIC insures Net.B@nk's deposits to the maximum extent provided by law.
The major functions of the FDIC with respect to insured federal savings banks
include:
 
    - Paying depositors to the extent provided by law in the event an insured
      federal savings bank is closed without adequately providing for payment of
      depositors' claims; and
 
    - Preventing the continuance or development of unsound and unsafe banking
      practices.
 
    CAPITAL REQUIREMENTS.  Net.B@nk is required to comply with the capital
adequacy standards established by the Office of Thrift Supervision. The Office
of Thrift Supervision has established three basic measures of capital adequacy
for federal savings banks--a risk-based measure, a leverage measure and a
tangible capital measure.
 
    The risk-based capital standards are designed to make regulatory capital
requirements more sensitive to differences in risk profiles among savings
associations, to account for off-balance-sheet exposure, and to minimize
disincentives for holding liquid assets. Assets and off-balance-sheet items are
assigned to broad risk categories, each with appropriate weights. The resulting
capital ratios represent capital as a percentage of total risk-weighted assets
and off-balance-sheet items.
 
    Under risk-based capital standards, the minimum guideline for the ratio of
total capital to risk-weighted assets is 8%. Net.B@nk's risk-based capital ratio
at December 31, 1998 was 15.36%.
 
    Under leverage-based capital standards, the minimum guideline for the ratio
of core capital to tangible assets is 3%. Net.B@nk's leverage ratio at December
31, 1998 was 9.31%. This leverage-based capital guideline, however, is the
minimum requirement. The guidelines provide that federal savings banks which are
not granted the highest regulatory rating shall maintain a core capital to total
adjusted assets ratio of 4%. A higher ratio may be required if warranted by the
risk profile of the federal savings bank.
 
    Under Office of Thrift Supervision regulations, core capital generally
includes:
 
    - Common stockholders' equity;
 
    - Noncumulative perpetual preferred stock and related surplus; and
 
    - Minority interests in the equity accounts of consolidated subsidiaries,
 
    LESS:
 
    - Unidentifiable intangible assets, other than certain amounts of
      supervisory goodwill; and
 
                                       53
<PAGE>
    - Certain investments in certain subsidiaries plus 90% of the fair market
      value of readily marketable purchased mortgage servicing rights and
      purchased credit card relationships, subject to certain conditions.
 
    Total capital, for purposes of the risk-based capital requirement equals the
sum of core capital plus supplementary capital. Supplementary capital includes
the sum of, among other items, perpetual preferred stock not counted as core
capital, limited life preferred stock, subordinated debt and general loan and
lease loss allowances up to 1.25% of risk-weighted assets less certain
deductions. The amount of supplementary capital that may be counted towards
satisfaction of the total capital requirement may not exceed 100% of core
capital, and Office of Thrift Supervision regulations require the maintenance of
a minimum ratio of core capital to total risk-weighted assets of 4%.
 
    Under tangible capital standards, the minimum guideline for the ratio of
tangible capital to tangible assets is 1.5%. Net.B@nk's tangible capital ratio
at December 31, 1998 was 9.31%. Generally, tangible capital is defined as core
capital minus intangible assets and investments in certain subsidiaries and does
not include purchased mortgage servicing rights.
 
    Office of Thrift Supervision regulations have been amended to include an
interest-rate risk component to the risk-based capital requirement. This new
requirement is not expected to have any material effect on our ability to meet
the risk-based capital requirement. The Office of Thrift Supervision also
revised its risk-based capital standards to ensure that its standards provide
adequately for concentration of credit risk, risk from nontraditional activities
and actual performance and expected risk of loss on multi-family mortgages.
 
    Capital requirements higher than the generally applicable minimum
requirement may be established for a particular savings association if the
Office of Thrift Supervision determines that the institution's capital was or
may become inadequate in view of its particular circumstances.
 
    Additionally, the Georgia Department of Banking and Finance requires savings
and loan holding companies, such as Net.B@nk, Inc., to maintain a 5% Tier 1
capital ratio on a consolidated basis. Tier 1 capital is substantially the same
as core capital. As of December 31, 1998, Net.B@nk's Tier 1 capital ratio was
14.44%.
 
    PROMPT CORRECTIVE ACTION.  The Federal Deposit Insurance Corporation
Improvement Act of 1991 established a system of prompt corrective action to
resolve the problems of undercapitalized institutions. Under this system, the
federal banking regulators, which include the Office of Thrift Supervision, the
FDIC, the Office of the Comptroller of the Currency and the Federal Reserve
Board, established five capital categories (well capitalized, adequately
capitalized, undercapitalized, significantly undercapitalized and critically
undercapitalized), and are required to take certain mandatory supervisory
actions, and are authorized to take other discretionary actions, relating to
institutions in the three undercapitalized categories. The severity of the
action depends upon the capital category in which the institution is placed.
Generally, subject to a narrow exception, the federal banking regulator must
appoint a receiver or conservator for an institution that is critically
undercapitalized. The federal banking agencies have specified by regulation the
relevant capital levels for each category.
 
    An institution that is categorized as undercapitalized, significantly
undercapitalized or critically undercapitalized is required to submit an
acceptable capital restoration plan to its appropriate federal banking agency. A
savings and loan holding company must guarantee that a subsidiary depository
institution meets its capital restoration plan, subject to certain limitations.
The controlling holding company's obligation to fund a capital restoration plan
is limited to the lesser of 5% of an undercapitalized subsidiary's assets or the
amount required to meet regulatory capital requirements. An undercapitalized
institution is also generally prohibited from increasing its average total
assets, making acquisitions, establishing any branches or engaging in any new
line of business, except under an accepted capital restoration plan or with FDIC
approval. In addition, the appropriate federal banking
 
                                       54
<PAGE>
agency may treat an undercapitalized institution in the same manner as it treats
a significantly undercapitalized institution, if it determines that those
actions are necessary. The appropriate federal banking agency may also treat an
institution in the well capitalized, adequately capitalized or undercapitalized
categories as if it was in the next lower category based on safety and soundness
considerations relating to factors other than capital levels.
 
    At December 31, 1998, our capital level placed us in the well capitalized
category.
 
    CAPITAL DISTRIBUTIONS.  Office of Thrift Supervision regulations govern the
payment of dividends and other capital distributions of savings associations
such as Net.B@nk. Under new regulations effective April 1, 1999, savings
associations that meet specified criteria must file a notice or an application
with the Office of Thrift Supervision before making a "capital distribution,"
which is defined to include dividends as well as stock repurchases and cash-out
mergers. Savings associations that do not meet these criteria are permitted to
make distributions without prior notice or application. The Office of Thrift
Supervision may deny distribution notices or applications under specified
circumstances.
 
    A savings association must file an application with the Office of Thrift
Supervision and receive the Office of Thrift Supervision's approval of the
application before making the distribution if:
 
    - The association is not eligible for expedited treatment under the agency's
      application processing guidelines;
 
    - The total amount of all of the association's capital distributions,
      including the proposed capital distribution, for the applicable calendar
      year exceeds the association's net income for that year to date plus the
      association's retained net income for the preceding two years;
 
    - The association would not be at least adequately capitalized under the
      Office of Thrift Supervision's prompt corrective action regulations,
      following the distribution; or
 
    - The proposed capital distribution would violate a prohibition contained in
      any applicable statute, regulation or agreement between the association
      and the Office of Thrift Supervision or the FDIC, or violate a condition
      imposed on the association in an application or notice approved by the
      Office of Thrift Supervision.
 
    A savings association is not eligible for expedited treatment if the
association does not have a composite rating of 1 or 2, does not have a
Community Reinvestment Act rating of satisfactory or better, does not have a
compliance rating of 1 or 2, does not meet its minimum capital requirements or
has been notified by Office of Thrift Supervision personnel that it is a problem
or troubled association.
 
    A savings association must file a notice 30 days before a capital
distribution if the association is not required to file an application but:
 
    - The association would not be well capitalized under the prompt corrective
      action regulations following the distribution;
 
    - The proposed capital distribution would reduce the amount of or retire any
      part of the association's common or preferred stock or retire any part of
      debt instruments such as notes or debentures included in capital under the
      Office of Thrift Supervision's capital regulations (other than regular
      payments required under certain debt instruments); or
 
    - The association is a subsidiary of a savings and loan holding company.
 
                                       55
<PAGE>
    The Office of Thrift Supervision may disapprove a notice or deny an
application, in whole or in part, if the Office of Thrift Supervision determines
that:
 
    - The association will be undercapitalized, significantly undercapitalized
      or critically undercapitalized as set forth in the prompt corrective
      action regulations, following the distribution;
 
    - The proposed distribution raises safety or soundness concerns; or
 
    - The proposed distribution violates a prohibition contained in any statute,
      regulation, agreement between the association and the Office of Thrift
      Supervision or the FDIC or a condition imposed in an application or notice
      approved by the Office of Thrift Supervision, unless the Office of Thrift
      Supervision decides to permit the proposed distribution notwithstanding
      the prohibition or condition.
 
    Net.B@nk does not currently meet the criteria for an application. However,
because Net.B@nk is a subsidiary of a savings and loan holding company, it must
file a notice with the Office of Thrift Supervision at least 30 days before it
makes any capital distribution.
 
    LIQUIDITY.  Under Office of Thrift Supervision regulations, savings
associations must maintain an average daily balance of liquid assets in each
calendar quarter of not less than 4% of: (1) the amount of its liquidity base at
the end of the preceding calendar quarter or (2) the average daily balance of
its liquidity base during the preceding quarter. Liquid assets include cash,
certain time deposits, certain bankers' acceptances, certain corporate debt
securities and highly rated commercial paper, securities of certain mutual funds
and specified United States government, state or federal agency obligations. The
liquidity base is the amount of the savings association's net withdrawable
accounts plus its short-term borrowings.
 
    The Office of Thrift Supervision may, to the extent and under conditions it
may prescribe, permit a savings association to reduce its liquid assets below
the minimum amount to meet withdrawals or pay obligations. In addition, the
Office of Thrift Supervision may suspend part or all of the minimum liquidity
requirements whenever it determines that conditions of national emergency or
unusual economic stress exist. Savings institutions also are required to
maintain short-term liquid assets to satisfy Federal Reserve Board requirements.
 
    QUALIFIED THRIFT LENDER REQUIREMENT. A federal savings bank is deemed to be
a qualified thrift lender if: (1) the savings association qualifies as a
domestic building and loan association, as defined in section 7701(a)(19) of the
Internal Revenue Code of 1986 or (2) the savings association's qualified thrift
investments equal or exceed 65% of its portfolio assets on a monthly average
basis in nine out of every 12 months.
 
    Qualified thrift investments generally consist of (1) various
housing-related loans and investments such as residential construction and
mortgage loans, home improvement loans, mobile home loans, home equity loans and
mortgage-backed securities, (2) certain obligations of the FDIC and (3) shares
of stock issued by any Federal Home Loan Bank, the Federal Home Loan Mortgage
Corporation or the Federal National Mortgage Association.
 
    In addition, the following assets may be categorized as qualified thrift
investments in an amount not to exceed 20% in the aggregate of portfolio assets:
 
    - 50% of the dollar amount of residential mortgage loans originated and sold
      within 90 days of origination;
 
    - Investments in securities of a service corporation that derives at least
      80% of its income from residential housing finance;
 
                                       56
<PAGE>
    - 200% of loans and investments made to acquire, develop or construct
      starter homes or homes in credit needy areas (subject to certain
      conditions);
 
    - Loans for the purchase or construction of churches, schools, nursing homes
      and hospitals; and
 
    - Consumer loans.
 
    The term portfolio assets means the savings institution's total assets minus
goodwill and other intangible assets, the value of property used by the savings
institution to conduct its business and liquid assets held by the savings
institution in an amount up to 20% of its total assets.
 
    A savings association that fails to meet the definition of a qualified
thrift lender must either convert to a national bank charter or limit its future
investments and activities, including branching and payments of dividends, to
those permitted for both savings associations and national banks. Further,
within one year of the loss of qualified thrift lender status, a holding company
of a savings association that does not convert to a bank charter must register
as a bank holding company and will be subject to all statutes applicable to bank
holding companies. In order to exercise the powers granted to federally
chartered savings associations and maintain full access to Federal Home Loan
Bank advances, Net.B@nk must continue to meet the definition of a qualified
thrift lender. In addition, Net.B@nk must continue to meet this definition for
Net.B@nk, Inc. to maintain its status as a unitary savings and loan holding
company.
 
    LOANS TO ONE BORROWER LIMITATIONS.  The Home Owners Loan Act generally
requires savings associations to comply with the loans to one borrower
limitations applicable to national banks. National banks generally may make
loans to a single borrower in amounts up to 15% of their unimpaired capital and
surplus, plus an additional 10% of capital and surplus for loans secured by
readily marketable collateral. The Home Owners Loan Act provides exceptions
under which a savings association may make loans to one borrower in excess of
the generally applicable national bank limits. A savings association may make
loans to one borrower in excess of the limits under the following circumstances:
(1) for any purpose, in any amount not to exceed $500,000 or (2) to develop
domestic residential housing units, in an amount not to exceed the lesser of $30
million or 30% of the savings association's unimpaired capital and unimpaired
surplus, provided other conditions are satisfied.
 
    The Federal Institutions Reform, Recovery, and Enforcement Act of 1989
provided that a savings association could make loans to one borrower to finance
the sale of real property which the savings association acquired in satisfaction
of debts previously contracted in good faith, in amounts up to 50% of the
savings association's unimpaired capital and unimpaired surplus. The Office of
Thrift Supervision, however, has modified this standard by limiting loans to one
borrower to finance the sale of real property acquired in satisfaction of debts
to 15% of unimpaired capital and surplus. That rule provides, however, that
purchase money mortgages received by a savings association to finance those
sales that do not constitute "loans" if no new funds are advanced and the
savings association is not placed in a more detrimental position holding the
note than holding the real estate. Therefore, these purchase money mortgages are
not subject to the loans to one borrower limitations.
 
    COMMERCIAL REAL PROPERTY LOANS.  The Home Owners Loan Act limits the
aggregate amount of commercial real estate loans that a federal savings
association may make to an amount not in excess of 20% of the savings
association's assets. Also, the amount in excess of 10% of total assets must be
devoted to small business real property loans.
 
    COMMUNITY REINVESTMENT.  Under the Community Reinvestment Act and the
implementing Office of Thrift Supervision regulations, federal savings banks
have a continuing and affirmative obligation to help meet the credit needs of
their local communities, including low and moderate-income neighborhoods,
consistent with the safe and sound operation of the institution. The Community
Reinvestment Act requires the boards of directors of financial institutions to
adopt a Community
 
                                       57
<PAGE>
Reinvestment Act statement for each assessment area that, among other things,
describes its efforts to help meet community credit needs and the specific types
of credit that the institution is willing to extend. The Office of Thrift
Supervision has established the following three tests to evaluate a federal
savings bank's compliance with the Community Reinvestment Act:
 
    - A lending test which will compare the institution's market share of loans
      in low- and moderate-income areas to its market share of loans in its
      entire service area and the percentage of a bank's outstanding loans to
      low- and moderate-income areas or individuals;
 
    - A services test which will evaluate the provision of services that promote
      the availability of credit to low- and moderate-income areas; and
 
    - An investment test, which will evaluate an institution's record of
      investments in organizations designed to foster community development,
      small- and minority-owned businesses and affordable housing lending,
      including state and local government housing or revenue bonds.
 
    FAIR LENDING.  Congress and various federal agencies, including bank
regulatory agencies, the Department of Housing and Urban Development, the
Federal Trade Commission and the Department of Justice, which are responsible
for implementing fair lending laws in the United States, have been increasingly
concerned that prospective home buyers and other borrowers are experiencing
discrimination in their efforts to obtain loans. In recent years, the Department
of Justice has filed suit against financial institutions that it determined had
discriminated, seeking fines and restitution for borrowers who allegedly
suffered from discriminatory practices. Most, if not all, of these suits have
been settled, some for substantial sums, without a full adjudication on the
merits.
 
    On March 8, 1994, these federal agencies, in an effort to clarify what
constitutes lending discrimination and to specify the factors the agencies will
consider in determining if lending discrimination exists, announced a joint
policy statement detailing specific discriminatory practices prohibited under
the Equal Credit Opportunity Act and the Fair Housing Act. In the policy
statement, three methods of proving lending discrimination were identified:
 
    - Overt evidence of discrimination, when a lender blatantly discriminates on
      a prohibited basis;
 
    - Evidence of disparate treatment, when a lender treats applicants
      differently based on a prohibited factor even where there is no showing
      that the treatment was motivated by prejudice or a conscious intention to
      discriminate against a person; and
 
    - Evidence of disparate impact, when a lender applies a practice uniformly
      to all applicants, but the practice has a discriminatory effect, even
      where the practices are neutral on their face and are applied equally,
      unless the practice can be justified on the basis of business necessity.
 
    FDIC INSURANCE ASSESSMENTS.  Federal deposit insurance is required for all
federally chartered savings associations. Net.B@nk's deposits are insured to a
maximum of $100,000 for each depositor by the Savings Association Insurance Fund
of the FDIC. Net.B@nk is therefore subject to regulation and supervision by the
FDIC to the extent deemed necessary by the FDIC to ensure the safety and
soundness of the Savings Association Insurance Fund. The FDIC is entitled to
have access to reports of examination of Net.B@nk made by the Office of Thrift
Supervision and all reports of condition filed by Net.B@nk with the Office of
Thrift Supervision. The FDIC also may require Net.B@nk to file additional
reports that determines to be advisable for insurance purposes. Additionally,
the FDIC may determine by regulation or order that a specific activity poses a
threat to the Savings Association Insurance Fund and that no Savings Association
Insurance Fund member may engage in the activity directly.
 
    Insurance premiums are paid in semiannual assessments. Under a risk-based
assessment system, the FDIC is required to calculate on a semi-annual basis a
savings association's semiannual assessment based on (1) the probability that
the insurance fund will incur a loss with respect to the institution,
 
                                       58
<PAGE>
taking into account the institution's asset and liability concentration, (2) the
potential magnitude of any such loss and (3) the revenue and reserve needs of
the insurance fund. The semiannual assessment imposed on the Net.B@nk may
increase depending on the Savings Association Insurance Fund revenue and expense
levels, and the risk classification applied to Net.B@nk.
 
    The FDIC has adopted a risk-based assessment system for insured depository
institutions that takes into account the risks attributable to different
categories and concentrations of assets and liabilities. The system assigns an
institution to one of three capital categories: (1) well capitalized; (2)
adequately capitalized; and (3) undercapitalized. These three categories are
substantially similar to the prompt corrective action categories described
above, with the "undercapitalized" category including institutions that are
undercapitalized, significantly undercapitalized, and critically
undercapitalized for prompt corrective action purposes. The FDIC also assigns an
institution to one of three supervisory subgroups within each capital group. The
supervisory subgroup to which an institution is assigned is based on a
supervisory evaluation that the Office of Thrift Supervision provides to the
FDIC and information that the FDIC determines to be relevant to the
institution's financial condition and the risk posed to the deposit insurance
funds. The FDIC determines an institution's insurance assessment rate based on
the institution's capital category and supervisory category.
 
    Since January 1, 1997, Savings Association Insurance Fund members and Bank
Insurance Fund members have the same risk-based assessment schedule which is
$0.00 to $0.27 per $100 of deposits. Beginning January 1, 1997, financing
corporate bond debt service assessments of $0.013 for Bank Insurance Fund
deposits and $0.064 per $100 of deposits for Savings Association Insurance Fund
deposits were added to the Bank Insurance Fund assessable base and Savings
Association Insurance Fund assessable base, respectively. These rates will be in
effect until December 31, 1999. Thereafter, approximately $0.024 per $100 of
deposits will be added to each regular assessment for all insured depositors.
 
    The Deposit Insurance Funds Act of 1996 provided that the Bank Insurance
Fund and the Savings Association Insurance Fund were to be merged, creating the
"Deposit Insurance Fund," on January 1, 1999, provided that bank and savings
association charters were combined by that date. The Treasury Department has
submitted a report to Congress on the development of a common charter for all
insured depository institutions, but as of January 1, 1999, Congress had not
passed any legislation to combine the charters. See "--Elimination of Federal
Savings Association Charter."
 
    The FDIC may terminate an institution's deposit insurance if it finds that
the institution has engaged in unsafe and unsound practices, is in an unsafe or
unsound condition to continue operation, or has violated any applicable law,
regulation, rule, order or condition imposed by the FDIC.
 
    FEDERAL HOME LOAN BANK SYSTEM.  The Federal Home Loan Bank System consists
of 12 regional Federal Home Loan Banks, each subject to supervision and
regulation by the Federal Housing Finance Board. The Federal Home Loan Banks
provide a central credit facility for member savings associations. Collateral is
required. The maximum amount that the Federal Home Loan Bank of Atlanta will
advance fluctuates from time to time in accordance with changes in policies of
the Federal Housing Finance Board and the Federal Home Loan Banks, and the
maximum amount generally is reduced by borrowings from any other source. In
addition, the amount of advances that a savings association may obtain from the
Federal Home Loan Banks will be restricted in the event the institution fails to
constitute a qualified thrift lender. Net.B@nk is a member of the Federal Home
Loan Bank of Atlanta.
 
    FEDERAL RESERVE SYSTEM.  The Federal Reserve Board has adopted regulations
that require savings associations to maintain non-earning reserves against their
transaction accounts, primarily NOW and regular checking accounts. These
reserves may also be used to satisfy liquidity requirements imposed by the
Office of Thrift Supervision. Because required reserves must be maintained in
the form of cash or a non-interest-bearing account at a Federal Reserve Bank,
the effect of this reserve requirement is to reduce the amount of our
interest-earning assets.
 
                                       59
<PAGE>
    Savings institutions also have the authority to borrow from the Federal
Reserve discount window. Collateral is required. Federal Reserve Board
regulations, however, require savings associations to exhaust all Federal Home
Loan Bank sources before borrowing from a Federal Reserve Bank.
 
    TRANSACTIONS WITH AFFILIATES RESTRICTIONS.  Net.B@nk is subject to the
provisions of Section 23A of the Federal Reserve Act and the Office of Thrift
Supervision's implementing regulation. Section 23A places limits on:
 
    - The amount of loans or extensions of credit to affiliates;
 
    - The amount of investment in affiliates;
 
    - The amount of the purchase of assets from affiliates, except for real and
      personal property exempted by the Federal Reserve Board;
 
    - The amount of loans or extensions of credit to third parties
      collateralized by the securities or obligations of affiliates; and
 
    - The amount of any guarantee, acceptance or letter of credit issued on
      behalf of an affiliate.
 
    The aggregate of all of the above transactions is limited in amount, as to
any one affiliate, to 10% of a bank's capital and surplus and, as to all
affiliates combined, to 20% of a bank's capital and surplus. In addition to the
limitation on the amount of these transactions, each transaction must also meet
specified collateral requirements. Net.B@nk must also comply with certain
provisions designed to avoid transactions with affiliates involving low-quality
assets.
 
    Net.B@nk is also subject to the provisions of Section 23B of the Federal
Reserve Act which, among other things, prohibits an institution from engaging in
the above transactions with affiliates unless the transactions are on terms
substantially the same, or at least as favorable to the institution or its
subsidiaries, as those prevailing at the time for comparable transactions with
nonaffiliated companies.
 
    Net.B@nk is also subject to certain restrictions on extensions of credit to
its executive officers, directors, certain principal shareholders and their
related interests. These extensions of credit (1) must be made on substantially
the same terms, including interest rates and collateral, as those prevailing at
the time for comparable transactions with third parties, and (2) must not
involve more than the normal risk of repayment or present other unfavorable
features.
 
    The Home Owners Loan Act and Office of Thrift Supervision regulations
contain additional restrictions on loans and extension of credit to affiliates,
and the Office of Thrift Supervision is authorized to impose additional
restrictions on transactions with affiliates if it determines restrictions are
necessary to ensure the safety and soundness of any savings association.
 
    FUTURE REQUIREMENTS.  Statutes and regulations are regularly introduced
which contain wide-ranging proposals for altering the structures, regulations
and competitive relationships of financial institutions. We cannot predict
whether or what form any proposed statute or regulation will be adopted or the
extent to which our business may be affected by such statute or regulation.
 
    ELIMINATION OF FEDERAL SAVINGS ASSOCIATION CHARTER.  In recent years,
Congress has considered legislation that would eliminate the federal savings
association charter. If this legislation is enacted, Net.B@nk likely would be
required to convert its federal savings bank charter to either a national bank
charter or to a state depository institution charter and Net.B@nk, Inc. would
become a bank holding company subject to regulation by the Federal Reserve Board
and the Georgia Department of Banking and Finance. Congress has also considered
various legislative proposals that would result in the restructuring of federal
regulatory oversight, including, for example, consolidation of the Office of
 
                                       60
<PAGE>
Thrift Supervision into another agency, or creation of a new Federal banking
agency to replace the various agencies which presently exist.

                  RELATIONSHIP WITH CAROLINA FIRST CORPORATION
 
    Carolina First Corporation owns more than five percent of our outstanding

Reserve Board regulations regarding its relationship with Net.B@nk. Therefore,
we have agreed with Carolina First Corporation that until they own less than
five percent of our outstanding common stock, we will not engage in any
activities that are not permissible banking or non-banking activities under
applicable Federal Reserve Board regulations. These regulations limit the
activities of bank holding companies and their affiliates to those that are
determined to be closely related to banking or to the management or control of
banks. We do not believe that these limitations will impose any material
constraints on our activities.

                          DESCRIPTION OF CAPITAL STOCK
 
    Our authorized capital stock consists of 100,000,000 shares of common stock,
$.01 par value, and 10,000,000 shares of preferred stock, no par value. The
following summary is qualified by reference to our Articles of Incorporation and
Bylaws, which are incorporated by reference as exhibits to the Registration
Statement of which this prospectus is a part.
 
COMMON STOCK
 
    Holders of our common stock are entitled to one vote per share in the
election of directors and on all other matters submitted to a vote of the
holders of common stock and do not have cumulative voting rights. The holders of
common stock are entitled to receive dividends, if any, as may be declared from
time to time by the Board of Directors out of legally available funds, and in
the event of liquidation, dissolution or winding-up of Net.B@nk, to share
ratably in all assets available for distribution.
 
PREFERRED STOCK
 
    The authorized preferred stock may be issued from time to time in one or
more designated series or classes. The Board of Directors, without approval of
the shareholders, is authorized to establish the voting, dividend, redemption,
conversion, liquidation and other relative provisions as may be provided in a
particular series or class. The issuance of preferred stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes, could, among other things, adversely affect the voting power of the
holders of common stock and, under certain circumstances, make it more difficult
for a third party to acquire, or discourage a third party from acquiring, a
majority of our outstanding voting stock. We have no present intention to issue
any series or class of preferred stock.
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
    Our Bylaws provide that special meetings of the shareholders may be called
at any time for any purpose by the Chief Executive Officer or by the presiding
officer of the Board of Directors. Either our Chief Executive Officer or the
Secretary is required to call a special meeting when (1) requested in writing by
any two or more of the directors or (2) requested in writing by shareholders
owning shares representing at least 25% of all the votes entitled to be cast on
any issue proposed to be considered at such meeting.
 
SUPERMAJORITY APPROVAL OF CERTAIN TRANSACTIONS
 
    Our Articles of Incorporation require the affirmative vote of the holders of
two-thirds of the voting stock to approve certain mergers, share exchanges and
dispositions of our assets unless at least two-thirds of the members of the
Board of Directors approve the proposed transaction. If such approval by the
Board of Directors is obtained, approval by the vote of a majority of the
outstanding shares entitled to vote is required. This provision may tend to
discourage attempts by third parties to acquire Net.B@nk in a hostile takeover
effort. It may also permit a minority of directors and shareholders to prevent a
business combination regardless of the terms of the proposed transaction.
 
CLASSIFIED BOARD AND REMOVAL OF DIRECTORS
 
    Our Articles of Incorporation also provide that the Board of Directors will
be divided into three classes serving staggered three-year terms and that a
director may only be removed by the vote of two-thirds of the outstanding shares
entitled to vote in an election of directors. These provisions could enable a
minority of our shareholders to prevent the removal of a director sought to be
removed by a
 
                                       66
<PAGE>
majority of the shareholders and may tend to enhance management's ability to
retain control over our affairs and to preserve the director's present position
on the Board.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Our Bylaws contain indemnification provisions providing that our directors,
officers and employees or agents will be indemnified against expenses actually
and reasonably incurred by them if they are successful on the merits of a claim
or proceeding.
 
    When a case or dispute is not ultimately determined on its merits (i.e., it
is settled), the indemnification provisions provide that Net.B@nk will indemnify
directors when they meet the applicable standard of conduct. The applicable
standard of conduct is met if the director acted in good faith and in a manner
he or she reasonably believed to be in or not opposed to the best interests of
Net.B@nk, and with respect to an employee benefit plan, for a purpose the
director believed in good faith to be in the interests of the participants and
beneficiaries of the plan. The standard of conduct with respect to any criminal
action or proceeding is met if the director had no reasonable cause to believe
his or her conduct was unlawful. Whether the applicable standard of conduct has
been met is determined by the Board of Directors, the shareholders or
independent legal counsel in each specific case.
 
    We can also provide for greater indemnification than that set forth in our
Bylaws if we choose to do so, subject to approval by our shareholders. We may
not, however, indemnify a director for liability arising out of circumstances
which constitute exceptions to limitation of a director's liability for monetary
damages. See "--Limitation of Liability."
 
    The indemnification provisions of the Bylaws specifically provide that we
may purchase and maintain insurance on behalf of any director against any
liability asserted against such person and incurred by him or her in any such
capacity, whether or not we would have had the power to indemnify against such
liability.
 
    We are not aware of any pending or threatened action, suit or proceeding
involving any of our directors or officers for which indemnification from
Net.B@nk may be sought.
 
LIMITATION OF LIABILITY
 
    Article X of our Articles of Incorporation, subject to certain exceptions,
eliminates the potential personal liability of a director for monetary damages
to Net.B@nk and to the shareholders of Net.B@nk for breach of a duty as a
director. There is no elimination of liability for:
 
    - A breach of duty involving appropriation of a business opportunity of
      Net.B@nk;
 
    - An act or omission not in good faith or involving intentional misconduct
      or a knowing violation of law;
 
    - A transaction from which the director derives an improper material
      tangible personal benefit; or
 
    - As to any payment of a dividend or approval of a stock repurchase that is
      illegal under the Georgia Business Corporation Code, our Articles of
      Incorporation do not eliminate or limit the right of Net.B@nk or its
      shareholders to seek injunctive or other equitable relief not involving
      monetary damages.
 
    We adopted Article X pursuant to the Georgia Business Corporation Code which
allows Georgia corporations, with the approval of their shareholders, to include
in their articles of incorporation a provision eliminating or limiting the
liability of directors, except in the circumstances described above. We included
Article X in our Articles of Incorporation to encourage qualified individuals to
serve and remain as directors of Net.B@nk. Article X was also included to
enhance our ability to secure liability
 
                                       67
<PAGE>
insurance for its directors at a reasonable cost. We maintain liability
insurance covering actions taken by its directors in their capacities as
directors. The Board of Directors believes that Article X will enable us to
secure such insurance on terms more favorable than if such a provision were not
included in the Articles of Incorporation.

    The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the shares of common stock
offered by this prospectus are subject to approval by their counsel of certain
legal matters and to other conditions customary in a firm commitment public
offering. The underwriters are required to purchase and pay for all the shares
of common stock offered by this prospectus, except for shares covered by the
over-allotment option described below, if any are purchased.
 
    The underwriters propose to offer the shares of common stock to the public
at the offering price listed on the cover page of this prospectus and to
securities dealers, including the underwriters, at the same price less a
concession of not more than $            per share. The underwriters may allow,
and the selected dealers may reallow, a concession not in excess of
$            per share to other brokers and dealers. After the consummation of
this offering, the offering price and other selling terms may be changed by the
underwriters. However, no change shall alter the amount of proceeds, as listed
on the cover page of this prospectus, to be received by us.
 
   
    We have granted the underwriters an option, exercisable within 30 days after
the date of this prospectus, to purchase from time to time, in whole or in part,
up to an aggregate of 450,000 additional shares of common stock. The
underwriters may exercise the option only to cover over-allotments, if any, made
in connection with this offering. To the extent that the underwriters exercise
the option, each underwriter will become obligated to purchase its pro rata
portion of the additional shares based on the underwriter's percentage
underwriting commitment in the offering, which is indicated in the preceding
table. If purchased, the additional shares will be sold by the underwriters on
the same terms as those on which they are selling the shares.
    
 
    We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments that the underwriters may be required to make in connection with these
liabilities.
 
    Other than in the United States, no action has been taken by us or the
underwriters that would permit a public offering of the shares of common stock
offered by this prospectus in any jurisdiction which requires action for that
purpose. The shares of common stock offered by this prospectus may not be
offered or sold, directly or indirectly, nor may this prospectus or any other
offering material or advertisements be distributed or published in any
jurisdiction, except under circumstances that will ensure compliance with the
applicable rules and regulations of the jurisdiction. Persons holding this
prospectus are advised to inform themselves about and to observe any
restrictions relating to this offering and the distribution of this prospectus.
This prospectus does not constitute an offer to sell or a solicitation of an
offer to buy any shares of common stock offered by this prospectus in any
jurisdiction in which an offer or a solicitation is unlawful.
 
                                       69
<PAGE>
    We and certain of our officers, directors and existing shareholders have
agreed that during the period beginning from the date of this prospectus and
continuing to and including the date 90 days after the date of this prospectus,
they will not, directly or indirectly, issue, sell, offer or agree to sell,
grant any option for the sale of, pledge, make any short sale, establish an open
"put equivalent position" within the meaning of Rule 16a-1(h) under the
Securities Exchange Act of 1934 or otherwise dispose of any shares of Net.B@nk
common stock (or securities which are convertible into, exercisable for or
exchangeable for common stock), without the prior written consent of Bear,
Stearns & Co. Inc., except under limited circumstances.
 
    Certain persons participating in this offering may engage in passive market
making transactions in the common stock in accordance with Rule 103 of
Regulation M under the Securities Exchange Act of 1934. Rule 103 permits, upon
the satisfaction of certain conditions, underwriting and selling group members
participating in a distribution that are also registered Nasdaq market makers in
the security being distributed, or a related security, to engage in limited
passive market making transactions during the period when Regulation M would
otherwise prohibit the activity. In general, a passive market maker may not bid
for or purchase a security at a price that exceeds the highest independent bid
for those securities by a person that is not participating in the distribution
and must identify its passive market making bids on the Nasdaq electronic
inter-dealer reporting system. In addition, the net daily purchases made by a
passive market maker generally may not exceed 30% of the market maker's average
daily trading volume in the security for the two full consecutive calendar
months, or any 60 consecutive days ending within 10 days, immediately preceding
the date of filing of the registration statement of which this prospectus is a
part.
 
    In connection with this offering, the underwriters may purchase and sell
common stock in the open market. These transactions may include over-allotment
and stabilizing transactions, and purchases to cover short positions created by
the underwriters in connection with this offering. Stabilizing transactions
consist of certain bids or purchases for the purpose of preventing or retarding
a decline in the market price of the common stock. Short positions involve an
underwriter's sale of a greater number of shares of common stock than it is
required to purchase from us in the offering. These activities may stabilize,
maintain or otherwise affect the market price of the common stock, which may be
higher than the price that might otherwise prevail in the open market. The
underwriter may effect these transactions on the Nasdaq National Market or
otherwise and may discontinue them at any time.
 
    In addition, the underwriters may maintain or stabilize the price of the
common stock by bidding for or purchasing shares of the common stock in the open
markets, and may impose penalty bids, under which selling concessions allowed to
syndicate members or other broker-dealers participating in this offering are
reclaimed if shares previously distributed in this offering are repurchased in
connection with stabilization transactions or otherwise. The imposition of
penalty bid may also affect the price of the common stock to the extent that it
discourages resales of the common stock. The underwriters can make no
representation as to the magnitude, duration or effect of any stabilization or
other transactions.
 
    The notes offered by the concurrent prospectus are a new issue of securities
with no established trading market. We have been advised by the underwriters
that they intend to make a market in the notes but are not obligated to do so
and may discontinue market making at any time without notice. No assurance can
be given as to the liquidity of the trading market for the notes.
 
    Each underwriter has represented and agreed that:
 
    - It has not offered or sold, and for up to six months following the
      consummation of this offering, will not offer or sell, any shares of
      common stock in the United Kingdom except to persons whose ordinary
      activities involve them in acquiring, holding, managing or disposing of
      investments (as principal or agent) for the purposes of their businesses
      or otherwise in
 
                                       70

      circumstances which do not constitute an offer to the public in the United
      Kingdom for the purposes of the Public Offers of Securities Regulations
      1995;
 
    - It has complied and will comply with all applicable provisions of the
      Financial Services Act 1986 with respect to anything done by it in
      relation to the common stock in, from or otherwise involving the United
      Kingdom; and
 
    - It has only issued or passed on and will only issue or pass on, in the
      United Kingdom, any document received by it in connection with the issue
      or sale of the common stock to a person who is of a kind described in
      Article 11(3) of the Financial Services Act 1986 (Investment
      Advertisements)(Exemptions) Order 1996 or to a person to whom the document
      may otherwise lawfully be issued or passed on.

    - Is a foreign broker-dealer with a principal place of business in the
      United Kingdom;
 
    - Is not registered with the Securities and Exchange Commission as a
      broker-dealer;
 
    - Is not a member of the National Association of Securities Dealers, Inc.;
 
    - Has agreed not to sell any of the shares of common stock offered by this
      prospectus within the United States, its territories or possessions or to
      nationals or residents of the United States, other than certain
      underwriting syndicate sales; and
 
    - Has agreed to comply with certain rules of the National Association of
      Securities Dealers Regulation, Inc. as if it were a member of the National

    Certain of the underwriters may from time to time perform investment banking
and other financial services for us for which they may receive advisory or
transaction fees, as applicable, plus out-of-pocket expenses, of the nature and
in amounts customary in the industry for these services. Bear, Stearns & Co.
Inc., Raymond James & Associates, Inc. and Kelton International Ltd.
participated in the public offering of our common stock on February 5, 1999 in
which we sold 7,290,000 shares.
 
    Concurrent with this offering we are offering by means of a separate
prospectus $100,000,000 aggregate principal amount of   % Convertible
Subordinated Notes Due 2004, plus an additional $15,000,000 principal amount of
notes to cover over-allotments by the underwriters of that offering. The
completion of this offering and of the notes offering do not depend upon one
another. The underwriters for the notes offering are also the underwriters for
this offering. The underwriters will receive customary compensation in
connection with the notes offering.

Board of Directors and Shareholders
 
Net.B@nk, Inc.
 
    We have audited the consolidated balance sheets of Net.B@nk, Inc. and its
subsidiary ("Net.B@nk") as of December 31, 1998 and 1997 and the related
consolidated statements of operations, shareholders' equity (deficit) and cash
flows for the years ended December 31, 1998 and 1997 and the period from
February 20, 1996 (date of incorporation) to December 31, 1996. These financial
statements are the responsibility of Net.B@nk'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, such consolidated financial statements present fairly, in
all material respects, the financial position of Net.B@nk as of December 31,
1998 and 1997, and the results of its operations and its cash flows for the
years ended December 31, 1998 and 1997 and the period from February 20, 1996
(date of incorporation) to December 31, 1996 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
         AS OF DECEMBER 31, 1997, 1998, AND (UNAUDITED) MARCH 31, 1999,
                   AND FOR THE PERIOD FROM FEBRUARY 20, 1996
                 (DATE OF INCORPORATION) TO DECEMBER 31, 1996,
        THE YEARS ENDED DECEMBER 31, 1997 AND 1998, AND (UNAUDITED) THE
                   THREE MONTHS ENDED MARCH 31, 1998 AND 1999
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
    Net.B@nk, Inc. ("Net.B@nk") is a bank holding company that wholly owns the
outstanding stock of Net.B@nk, formerly Atlanta Internet Bank, a federal savings
bank. Net.B@nk, Inc. was incorporated as a Georgia corporation on February 20,
1996, for the primary purpose of forming and, ultimately, operating Net.B@nk.
During the period from February 20, 1996 to July 31,1997, pending regulatory
approval and the acquisition of a bank charter, Net.B@nk was operating as a
development stage enterprise under an agreement with Carolina First Bank
("CFB"), a wholly owned subsidiary of Carolina First Corporation ("CFC"),
whereby CFB agreed to hold and service the deposit accounts generated by the
Internet banking operations of Net.B@nk in exchange for 3,975,000 shares of
Net.B@nk's common stock valued at $3,840,000. In addition, during the period
from February 20, 1996 to July 31, 1997, Net.B@nk was a party to an agreement
with First Alliance/Premier Bancshares, Inc. ("First Alliance") pursuant to
which Net.B@nk had agreed to purchase the charter of First Alliance's
subsidiary, Premier Bank, $5 million of loans, $5 million of certificates of
deposit and $2 million in unimpaired capital for $2,150,000 in cash, 124,218
shares of Net.B@nk's common stock valued at $125,000 and $75,000 in additional
cash for reimbursement of direct out-of-pocket expenses.
 
    On July 11, 1997, the final regulatory approval from the Office of Thrift
Supervision ("OTS") was received. On July 31, 1997, Net.B@nk received
approximately $38.4 million in net proceeds from the sale of 10,500,000 shares
of its common stock in an Initial Public Offering (the "IPO") and consummated
its agreements with both First Alliance and CFB. As a result, Net.B@nk, a
federal savings bank, became a wholly owned subsidiary of Net.B@nk, Inc. On
February 10, 1999, Net.B@nk received net proceeds of approximately $105,000,000
from the sale of an additional 7,290,000 shares of its common stock in a public
offering.
 
2. ACCOUNTING POLICIES
 
    The accounting and reporting policies of Net.B@nk conform with generally
accepted accounting principles and with general practice within the banking
industry. The following is a summary of the more significant policies:
 
    CONSOLIDATION--The consolidated financial statements of Net.B@nk, Inc.
include the financial statements of Net.B@nk, Net.B@nk, Inc.'s wholly owned
subsidiary. All intercompany balances and transactions have been eliminated in
consolidation.
 
    USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS--The preparation
of financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect the
reported amounts of assets and 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.
 
    INTEREST RATE RISK--Net.B@nk's assets and liabilities are generally monetary
in nature and interest rate changes have an impact on Net.B@nk's performance.
Net.B@nk decreases the effect of interest rate changes on its performance by
striving to match maturities and interest sensitivity between loans,

2. ACCOUNTING POLICIES (CONTINUED)
investment securities, deposits, and other borrowings. However, a significant
change in interest rates, specifically the prime rate, could have a material
effect on Net.B@nk's results of operations.
 
    CASH AND CASH EQUIVALENTS--For purposes of reporting cash flows, cash and
cash equivalents include cash on hand, demand deposits due from banks, and
federal funds sold to banks.
 
    INVESTMENT SECURITIES AVAILABLE FOR SALE--Investment securities classified
as available-for-sale are carried at fair value. Unrealized holding gains or
losses, net of tax, on available-for-sale securities are reported as a net
amount in other comprehensive income. Gains and losses from dispositions are
based on the net proceeds and the adjusted carrying amounts of the securities
sold using the specific identification method. Any decreases in investment value
other than temporary declines would be recognized in operations. Premiums and
discounts are recognized in interest income using the interest method over the
period to maturity.
 
    DEFERRED FEES AND COSTS--Loan origination fees and certain direct
origination costs are capitalized and recognized as an adjustment of the yield
of the related loans.
 
    ALLOWANCE FOR LOAN LOSSES--The allowance for loan losses is maintained at a
level estimated to be adequate to provide for probable losses in the loan
portfolio. As the majority of Net.B@nk's portfolio is purchased, an estimate of
the loss inherent in the purchased portfolio is made and an allowance for loan
losses is recorded by adjusting the premium associated with the purchased loans.
Management determines the adequacy of the allowance based upon reviews of
individual loans, recent loss experience, current economic conditions, the risk
characteristics of the various categories of loans and other pertinent factors.
Loans deemed uncollectible are charged to the allowance. Provisions for loan
losses and recoveries on loans previously charged off are added to the
allowance.
 
    FURNITURE AND EQUIPMENT--Furniture and equipment are stated at cost less
accumulated depreciation. Depreciation is computed using the straight-line
method over the estimated useful life of each asset. Net.B@nk evaluates the
estimated useful lives of assets on a periodic basis to determine whether events
or circumstances warrant revised estimated useful lives or whether any
impairment exists. Management believes no impairment existed at December 31,
1998.
 
    BANK CHARTER--The value of the charter is being amortized on a straight-line
basis over 25 years. The carrying value of the charter is periodically reviewed
to assess recoverability based on expected undiscounted cash flows and operating
income of Net.B@nk. Impairment would be recognized in operating results if a
permanent diminution in value was expected. Net.B@nk also evaluates the
amortization period of the bank charter to determine whether events or
circumstances warrant revised estimates of the useful life. Management believes
that no impairment of the bank charter existed at December 31, 1998.
 
    INTEREST INCOME ON LOANS--Interest on loans is generally recorded over the
term of the loan based on the unpaid principal balance. Accrual of interest is
discontinued when either principal or interest becomes 90 days past due or when,
in management's opinion, collectibility of such interest is doubtful. In
addition, any previously accrued interest is reversed when the loan becomes 90
days past due.
 
    PREMIUM ON LOANS PURCHASED--Premiums on loans purchased from third parties
are capitalized and amortized over the average life of the loan as an adjustment
to yield. Such premiums are classified with the loan balance to which they
relate for financial reporting purposes.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES--Provisions for income taxes are based upon amounts reported in
the statements of income and include deferred taxes for net operating loss
carryforwards and temporary differences between financial statement and tax
bases of assets and liabilities using enacted tax rates for the year in which
the temporary differences are expected to reverse. Net.B@nk records a valuation
allowance when management believes it is more likely than not that deferred tax
assets will not be realized.
 
    NET INCOME (LOSS) PER SHARE--In February 1997, Statement of Financial
Accounting Standards 128, EARNINGS PER SHARE ("SFAS 128") was issued. SFAS 128
establishes standards for computing and presenting earnings per share
information for entities with publicly held common stock. In accordance with
SFAS 128, basic net income per share is computed based on the weighted average
number of common shares outstanding during the period. Diluted net income per
share is computed based on the weighted average number of common and potential
dilutive common shares outstanding during the period. All previously reported
per share amounts have been restated to conform to SFAS 128.
 
    RECLASSIFICATIONS--Certain reclassifications have been made to the 1996 and
1997 financial statements to conform to the 1998 presentation.
 
    UNAUDITED INTERIM FINANCIAL STATEMENTS--The financial statements as of March
31, 1998 and 1999 and for the three months ended March 31, 1998 and 1999, were
prepared on the same basis as the audited consolidated financial statements and,
in the opinion of management, include all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of the financial
position and results of operations for these periods. Certain information and
note disclosures normally included in the consolidated financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the rules and regulations relating to interim
financial statements. Operating results for the interim periods included herein
are not necessarily indicative of the results that may be expected for the
entire year.
 
    NEW ACCOUNTING PRONOUNCEMENTS--As of January 1, 1998, Net.B@nk adopted
Statement of Financial Accounting Standards 130, REPORTING COMPREHENSIVE INCOME
("SFAS 130"), and restated prior periods to conform to the presentation required
by SFAS 130. SFAS 130 establishes new rules for the reporting and display of
comprehensive income and its components. SFAS 130 requires unrealized gains or
losses, net of tax, on Net.B@nk's available-for-sale securities, which prior to
adoption were reported separately in shareholders' equity, to be included in
other comprehensive income. The adoption of SFAS 130 had no impact on Net.B@nk's
net income or shareholders' equity.
 
    As of April 1, 1998, Net.B@nk adopted Statement of Position 98-1, ACCOUNTING
FOR THE COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED FOR INTERNAL USE ("SOP
98-1"). SOP 98-1 allows for the capitalization of costs related to the
development and implementation of software obtained for internal use including
materials, payroll, and interest costs once the criteria of the SOP have been
met. As of December 31, 1998, $592,402 of these related costs had been
capitalized.
 
    As of December 31, 1998, Net.B@nk adopted SFAS 131, DISCLOSURES ABOUT
SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. SFAS 131 establishes annual
and interim reporting standards for an enterprise's business segments and
related disclosures about its products, services, geographic areas, and major
customers. The adoption of SFAS 131 had no effect on Net.B@nk's financial
statements for the year ended December 31, 1998 because Net.B@nk only has one
reportable segment-banking.

2. ACCOUNTING POLICIES (CONTINUED)
    In June 1998, Statement of Financial Accounting Standards 133, ACCOUNTING
FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES ("SFAS 133"), was issued. SFAS
133 establishes standards for derivative instruments and hedging activities and
requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. SFAS 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. The adoption of SFAS 133 is not expected to have
a significant effect on Net.B@nk's financial statements.
 
3. ACQUISITION
 
    Effective July 31, 1997, Net.B@nk acquired all of the outstanding stock of
Premier Bank, FSB for $2,150,000 in cash, 124,218 shares of Net.B@nk's common
stock valued at $125,000 and $75,000 in additional cash for reimbursement of
direct out-of-pocket expenses. The acquisition was accounted for as a purchase
and the bank charter was recorded at $350,000. This amount is being amortized
over 25 years. Revenues, net loss, and basic and diluted net loss per common
share and potential dilutive common share for Net.B@nk for the period from
February 20, 1996 to December 31, 1996 or for the year ended December 31, 1997
would not have been materially affected assuming the transaction had occurred on
February 20, 1996 and January 1, 1997, respectively.

</TABLE>
 
    Net.B@nk considers a loan to be impaired when it is probable that it will be
unable to collect all amounts due according to the original terms of the loan
agreement. Net.B@nk measures impairment of a loan on a loan by loan basis.
Amounts of impaired loans that are not probable of collection are charged off
immediately. During the years ended December 31, 1997 and 1998, Net.B@nk had no
significant amount of impaired loans or nonaccrual loans. The amount of impaired
loans written off during the years ended December 31, 1997 and 1998 was $18,262
and $587,138, respectively. Net.B@nk had no restructured loans as of either
December 31, 1997 or 1998.
 
    Net.B@nk is a party to financial instruments with off-balance-sheet risk in
the normal course of its lending activities to meet the financing needs of its
customers. These financial instruments include commitments to extend credit and
lines of credit. Net.B@nk's exposure to credit loss in the event of
nonperformance by the other party to the financial instrument for commitments to
extend credit and standby letters of credit is represented by the contractual
amount of those instruments. Net.B@nk uses the same credit policies in making
these commitments as it does for on-balance-sheet instruments and evaluates each
customer's creditworthiness on a case-by-case basis. At December 31, 1997 and
1998, Net.B@nk had outstanding loan commitments of $8,332,568 and $47,617,700,
respectively.
 
    The amount of collateral obtained by Net.B@nk, if deemed necessary, for
these commitments, upon extension of credit, is based on management's credit
evaluation of the customer. Collateral held, if any, varies but may include
inventory, equipment, real estate, or other property. The accounting loss
Net.B@nk would incur if the borrower failed completely to perform according to
the terms of the contract and the collateral proved to be of no value is equal
to the face amount of the commitment.
 
7. LOAN ORIGINATION AGREEMENTS
 
    During the year ended December 31, 1998, Net.B@nk entered into separate
agreements with three unrelated third parties whereby Net.B@nk acts as a loan
originator on behalf of the third parties. Under the terms of the agreements,
the third parties are required to purchase all loans, including the related
servicing of these loans, originated by Net.B@nk, unless Net.B@nk elects to
retain the loans. As a result of the agreements, loans originated for the third
parties for which the purchase price has not yet been received are accounted for
as receivables.

    During the year ended December 31, 1998, Net.B@nk, Inc. and its subsidiary,
Net.B@nk, entered into line of credit agreements with The Bankers Bank.
Net.B@nk, Inc. is a party to one such agreement and its subsidiary, Net.B@nk, is
a party to two such agreements. Under the terms of Net.B@nk, Inc.'s agreement
which expired on October 20, 1998, Net.B@nk, Inc. could borrow 50% of the
tangible equity of Net.B@nk, up to $17 million, using the stock of Net.B@nk as
collateral. Any amounts borrowed under this line had interest at a fixed rate of
8.00% per annum. During the year ended December 31, 1998, Net.B@nk, Inc.
borrowed and repaid $12 million under the line. Under the terms of the other two
agreements, the subsidiary, Net.B@nk, may borrow $5 million under an unsecured
general purpose line and 99% of the value of its investment securities under
another line. Both of the lines bear interest at 25 basis points above the
Federal Funds rate (5.00% at December 31, 1998). Under these agreements at
December 31, 1998, the subsidiary, Net.B@nk, had an outstanding borrowing of $20
million with no stated maturity secured by investment securities.
 
    As of March 31, 1999, the subsidiary, Net.B@nk, has borrowed $20 million
from the Federal Home Loan Bank ("FHLB") at a fixed rate of 4.43%. The borrowing
is callable at the two-year anniversary date. If not called at the two-year
date, the borrowing extends for an additional three years at 4.435%. Also, the
subsidiary, Net.B@nk, has borrowed $25 million from the Federal Home Loan Bank
at a fixed rate of 4.64%. The borrowing is callable at the two-year anniversary
date. If not called at the two-year date, the borrowing extends for an
additional eight years at 4.64%. These borrowings are secured by Net.B@nk's
investment securities.

    Rent expense for the period from February 20, 1996 (date of incorporation)
to December 31, 1996, and for the years ended December 31, 1997 and 1998, was
$17,850, $91,868, and $110,011, respectively.
 
11. INCOME TAXES
 
    Net.B@nk provides deferred income taxes for net operating loss carryforwards
and for temporary differences between financial statement and tax bases of
assets and liabilities using enacted tax rates in effect for the year in which
the temporary differences are expected to reverse. As of December 31, 1998,
Net.B@nk had state and federal net operating loss carryforwards of $6,182,993
which will expire in 2012 and 2011, if not utilized.
 
    Net.B@nk did not incur any income taxes during 1996 and 1997. For the year
ended December 31, 1998, Net.B@nk's income tax benefit results from the reversal
of the valuation allowance as of December 31, 1997, relating to net operating
loss carryforwards offset by taxable income for the period. As Net.B@nk achieved
profitability in 1998, management now believes that it is more likely than not
that such assets will be realized, and thus, reversed the valuation allowance in
accordance with SFAS 109, ACCOUNTING OF INCOME TAXES.

13. EMPLOYEE BENEFIT PLAN
 
    Effective December 31, 1997, Net.B@nk adopted a 401(k) plan (the "Plan")
which covers substantially all of its employees. Net.B@nk, at its discretion,
matches 25% of employee contributions to the Plan, up to a maximum Company
contribution of 1% of an employee's compensation. Net.B@nk expensed $10,100
during 1998 related to the plan.
 
14. SHAREHOLDERS' EQUITY
 
    On March 17, 1997, Net.B@nk declared a 33.125 for one split of its common
stock effected in the form of a stock dividend payable on the effective date of
the initial public offering. All references to share and per share amounts
reflect the split. Also, additional paid-in capital has been charged and common
stock has been credited retroactively with $12,116 to reflect the stock split.
 
    On February 10, 1999, Net.B@nk received net proceeds of approximately
$105,000,000 from the sale of 7,290,000 shares of its common stock in a public
offering.
 
    On April 13, 1999, Net.B@nk declared a three-for-one split of its common
stock effected in the form of a stock dividend payable on May 14, 1999 to
shareholders of record as of the close of business on April 23, 1999. All
references to share and per share amounts have been retroactively adjusted to
reflect the split.
 
    Under current OTS regulations, Net.B@nk may pay dividends and make other
capital distributions after giving notice to the Office of Thrift Supervision.
 
15. STOCK OPTIONS
 
    Net.B@nk has a 1996 Stock Incentive Plan (the "Plan"), which provides that
key employees, officers, directors, and consultants of Net.B@nk may be granted
nonqualified and incentive stock options to purchase shares of common stock of
Net.B@nk, derivative securities related to the value of the common stock, or
cash awards. Previously, the Plan limited the number of shares which could be
awarded to 1,800,000. Effective with shareholder approval on April 22, 1999, the
Plan was amended to increase the total number of shares reserved for the Plan to
3,750,000. Generally, the options expire ten years from the date of the grant.

16. EARNINGS PER SHARE
 
    Basic and diluted net income (loss) per common and potential common share
have been calculated based on the weighted average number of shares outstanding
in accordance with SFAS 128. In accordance with SFAS 128, the following schedule
reconciles the numerators and denominators of the basic and diluted net income
per common and potential common share. The only periods presented relate to
those with net income as diluted securities would be anti-dilutive to periods
with a net loss. Net.B@nk had options to purchase common stock outstanding of
49,686 and 1,099,368 at December 31, 1996 and 1997, respectively.

17. CAPITAL ADEQUACY
 
    Net.B@nk is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure of Net.B@nk to meet minimum capital
requirements can initiate certain mandatory and possibly additional
discretionary actions by regulators that, if undertaken, could have a direct
material effect on Net.B@nk's consolidated financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
Net.B@nk must meet specific capital guidelines that involve quantitative
measures of Net.B@nk's assets, liabilities, and certain off-balance-sheet items
as calculated under regulatory accounting practices. Net.B@nk's capital amounts
and classifications are also subject to qualitative judgments by the regulators
about components, risk weightings, and other factors. In addition, under
regulatory guidelines, Net.B@nk may not pay a dividend to Net.B@nk, Inc. if
doing so would cause Net.B@nk to be less than adequately capitalized, as defined
below.
 
    Quantitative measures established by regulation to ensure capital adequacy
require Net.B@nk to maintain minimum amounts and ratios set forth in the table
below. Net.B@nk's regulatory agency, the OTS, requires Net.B@nk to maintain
minimum ratios of tangible capital to tangible assets of 1.5%, core capital to
tangible assets of 3.0%, and total risk-based capital to risk-weighted assets of
8.0%. Management believes, as of December 31, 1998, that Net.B@nk meets all the
capital adequacy requirements to which it is subject.
 
    As of December 31, 1998, the most recent notification from the OTS
categorized Net.B@nk as well capitalized under the regulatory framework for
prompt corrective action. To be well capitalized Net.B@nk must maintain minimum
total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in
the table. There are no conditions or events since that notification that
management believes would have changed the institution's category.
 
    Net.B@nk's actual capital amounts and ratios as of December 31, 1997 and
1998, are as follows (dollars in thousands):

    The carrying amounts of cash and due from banks and federal funds sold are a
reasonable estimate of their fair value due to the short-term nature of these
financial instruments. The fair value of investment securities and loans is
based on quoted market prices and dealer quotes. The fair value of time deposits
and other borrowed funds is estimated by discounting the future cash flows using
Net.B@nk's current interest rates for such financial instruments.
 
    As required by SFAS 107, demand deposits are shown at their face value. No
additional value has been ascribed to core deposits, which generally bear a low
rate of or no interest and do not fluctuate in response to changes in interest
rates.

    The fair value estimates presented herein are based on pertinent information

not aware of any factors that would significantly affect the estimated fair
value amounts, such amounts have not been comprehensively revalued for purposes
of these financial statements since that date and, therefore, current estimates
of fair value may differ significantly from the amounts presented herein.

SPLIT IN THE FORM OF A STOCK DIVIDEND, WHICH HAS A RECORD DATE OF APRIL 23, 1999
AND A DISTRIBUTION DATE OF MAY 14, 1999. REFERENCES TO "WE," "US," "OUR" AND
"NET.B@NK" GENERALLY REFER TO NET.B@NK, INC. AND ITS SOLE SUBSIDIARY, NET.B@NK,
ON A CONSOLIDATED BASIS, EXCEPT WHERE WE INDICATE THAT NET.B@NK, INC. MEANS ONLY
THE PARENT ENTITY AND NET.B@NK REFERS ONLY TO THE BANKING SUBSIDIARY.
 
OUR BUSINESS
 
    Net.B@nk, our sole subsidiary, is the largest federally-insured bank
operating exclusively on the internet. Our mission is to profitably provide a
broad range of banking and financial services to the growing number of internet
users. Our low cost branchless business model allowed us to attain profitability
within a year of acquiring our bank charter and to continue to maintain
profitability while passing along our operating cost savings to customers in the
form of attractive interest rates and low fees.
 
    Our unique, internet-based operating strategy has allowed us to experience
rapid growth. During 1998, our customer accounts grew from 4,755 to 17,408,
deposits grew from $58.7 million to $283.6 million and total assets grew from
$93.2 million to $388.4 million. During 1998, we added an average of 1,054 net
customer accounts per month. At March 31, 1999, we had 24,634 customer accounts,
$332.7 million in deposits and $526.5 million in total assets. During the four
months ended April 30, 1999, we added an average of over 2,900 net customer
accounts per month with 4,865 added in April alone.
 
    We offer a broad array of products and services that customers would
typically expect from a traditional bank. Our products and services include
checking and money market accounts, certificates of deposit, electronic bill
payment, debit cards, credit cards, mortgage loans, business equipment leases
and securities brokerage services. We plan to offer consumer loans, including
home equity and automobile loans, beginning in the third quarter of 1999. We
also intend to develop additional products and services such as insurance
products, electronic bill presentment and electronic document and image storage
in a virtual safe deposit box.
 
    Since our equity offering in February 1999, we have continued to experience
rapid growth in our business and have entered into several new programs to
expand and improve our operational and product capabilities. Since February
1999, we have initiated the following:
 
    - EXPANDED MARKETING PROGRAM. We embarked on a new marketing program that
      has been highly successful in reaching our targeted audience and has
      produced a significant increase in checking accounts. We believe this
      growth in our checking account base indicates growing customer willingness
      to move their everyday banking activities to Net.B@nk and will result in
      long-term customer relationships. Furthermore, we believe that our
      checking account customers will visit our Web site more frequently and
      spend more time on our Web site, allowing us to cross-sell a variety of
      other products and services.
 
    - SERVICING AGREEMENT WITH PNC BANK CORP. We entered into a consumer loan
      processing and servicing agreement with PNC Bank Corp. This agreement will
      allow us to offer consumer loan products on-line. PNC will provide
      origination and loan servicing for these consumer loans as well as
      substantially all consumer loans for which we retain servicing rights on a
      scalable basis at a favorable cost.
 
    - IMPROVED CUSTOMER SERVICE. We increased our customer support staff by over
      70% in order to maintain high-quality customer service. We have also
      invested in advanced technology and
 
                                       3
<PAGE>
      implemented new procedures in order to continually improve the quality and
      responsiveness of our customer service.
 
    - STRENGTHENED LENDING AND FINANCIAL OPERATIONS. We expanded our mortgage
      lending capabilities through a mortgage loan origination partnership with
      Virtuallender.com. We strengthened our lending and financial operations by
      adding several experienced individuals to our professional staff.
      Additionally, we have significantly increased our loan portfolio while
      continuing to maintain a conservative lending and investment strategy.
 
OUR MARKET OPPORTUNITY
 
    By offering a broad array of financial services via the internet, we are
well-positioned to capitalize on the internet's rapid growth. According to
International Data Corporation, the number of worldwide internet users is
projected to grow from an estimated 159.3 million in 1998 to an estimated 410.4
million by 2002. The internet is emerging rapidly as a means of providing
financial services. According to Jupiter Communications, the number of on-line
banking households in the United States is projected to grow from an estimated
6.6 million in 1998 to an estimated 17.1 million in 2002. A demographic study by
Jupiter Communications indicates that internet users tend to be young, mobile
professionals with relatively high incomes. We believe these demographics
suggest a growing market for the convenience, attractive interest rates and low
fees that characterize Net.B@nk.
 
    As the first federally-insured bank to operate solely on the internet, we
have a first mover advantage relative to on-line banks with less extensive
market presence and less established operating histories. In addition, we have a
competitive cost advantage over traditional banks.
 
OUR STRATEGY
 
    Our objective is to become the leading provider of a full range of on-line
financial services. To accomplish this objective, we intend to:
 
    - Build national brand awareness through increased marketing efforts.
 
    - Expand our customer base by offering attractive interest rates and low
      fees, a result of our low-cost, branchless business model.
 
    - Develop new products and services and enter into strategic alliances where
      appropriate.
 
    - Employ a conservative lending and investment strategy to maintain high
      asset quality.
 
    - Outsource operational functions to provide scalability and flexibility.
 
    - Generate noninterest income through cross-marketing initiatives.

                               incur, assume or guarantee.

Use of proceeds..............  We intend to invest the majority of the net proceeds from
                               this offering in earning assets, including purchased loan
                               portfolios, new loans that we originate and investment
                               securities. We intend to use the earnings from these assets
                               and the balance of the net proceeds from this offering for
                               general corporate purposes, including increasing our
                               budgeted marketing efforts to $11.0 million for the next
                               twelve months. We also intend to hire additional personnel,
                               to fund other costs related to our accelerated deposit
                               growth and to pursue strategic partnerships and investments.

Concurrent common stock
  offering...................  Concurrent with this notes offering and by means of a
                               separate prospectus, we are offering 3,000,000 shares of our
                               common stock, plus an additional 450,000 shares to cover

- ------------------------
 
(1) On April 13, 1999, we declared a 3 for 1 split of our common stock to be
    effected in the form of a stock dividend payable on May 14, 1999 to
    shareholders of record as of the close of business on April 23, 1999. All
    references to share and per share amounts have been retroactively adjusted
    to reflect this split.
 
(2) Assuming no income tax benefit and a statutory income tax rate of 34% for
    the year, pro forma net income per common and potential common share for the
    year ended December 31, 1998 would have been $0.03 per share, basic, and
    $0.02 per share, diluted.
 
(3) For purposes of computing this ratio, earnings available for fixed charges
    consist of earnings (loss) before provision for income taxes and fixed
    charges. Fixed charges consist of interest expense plus such portion of
    rental expense as is representative of the interest factor. Deficiencies in
    earnings to fixed charges for the period from February 20, 1996 to December
    31, 1996, the year ended December 31, 1997 and the three months ended March
    31, 1998 were $3,838,182, $6,677,439 and $151,447, respectively.

                                  RISK FACTORS
 
    AN INVESTMENT IN THE NOTES INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CAREFULLY CONSIDER THE SPECIFIC FACTORS LISTED BELOW, TOGETHER WITH THE
CAUTIONARY STATEMENT THAT FOLLOWS THIS SECTION AND THE OTHER INFORMATION
INCLUDED IN THIS PROSPECTUS BEFORE PURCHASING THE NOTES.
 
    THE NOTES ARE NOT SAVINGS ACCOUNTS, DEPOSITS OR OTHER OBLIGATIONS OF A BANK
OR SAVINGS ASSOCIATION AND ARE NOT INSURED BY THE FDIC OR ANY OTHER GOVERNMENTAL
AGENCY.
 
WE COULD SUSTAIN LOSSES IF THE QUALITY OF OUR LOAN PORTFOLIO DETERIORATES
 
    If the quality of our loan portfolio deteriorates due to economic downturns
or our inaccurate assessment of borrower creditworthiness, our interest income
and net interest margin could decrease and our loan loss provision could
increase. This could result in losses that materially adversely affect our
business, financial condition, results of operations and cash flows. A
significant portion of our net income is derived from our loan portfolio. If an
economic downturn occurs either generally or in the Western or Southeastern
United States, the regions collectively representing the greatest concentration
of loans in our loan portfolio, borrowers may be less likely to repay their
loans as scheduled.
 
OUR SUCCESS DEPENDS ON THE CONTINUED GROWTH IN USE AND COMMERCIAL VIABILITY OF
  THE INTERNET
 
    Our future success depends substantially on continued growth in use of the
internet. The internet is, however, a relatively new commercial marketplace and
may not continue to grow. If internet use does not continue to grow, our
business, financial condition, results of operations and cash flows could be
materially adversely affected.
 
    Additionally, to the extent the internet's technical infrastructure or
security concerns adversely affect its growth, our business, financial
condition, results of operations and cash flows could be materially adversely
affected. If the number of internet users and the level of use continues to
grow, the internet's technical infrastructure may become unable to support the
demands placed upon it. Furthermore, third-party vendors might not be able to
timely and adequately develop the necessary technical infrastructure for
significant increases in electronic commerce, such as a reliable network
backbone, or to introduce performance improvements, such as high-speed modems.
The internet could also lose its commercial viability due to delays in the
development or adoption of new standards and protocols required to handle
increased levels of activity or due to increased governmental regulation.
Changes in or insufficient availability of telecommunication services could
produce slower response times and adversely affect use of the internet.
Furthermore, the general public's security concerns regarding the transmittal of
confidential information, such as credit card numbers, over the internet might
persist or even worsen. These security concerns could lead to resistance against
widespread acceptance of the internet as a viable commercial marketplace.
 
OUR OPERATIONS COULD BE INTERRUPTED IF OUR NETWORK OR COMPUTER SYSTEMS FAIL OR
  EXPERIENCE A SECURITY BREACH
 
    Interruptions in our operations resulting from damage or failure of our
network or computer system could materially adversely affect our business,
financial condition, results of operations and cash flows. Because we conduct
our business over the internet and outsource several critical functions to third
parties, our operations depend on our ability, as well as that of our
third-party service providers, to protect our computer systems and network
infrastructure against damage from fire, power loss, telecommunications failure,
physical break-ins or similar catastrophic events. Our computer systems and
network infrastructure could be vulnerable to unforeseen problems.
 
    In addition, any compromise or breach of our network or computer system
security could have a material adverse effect on our business, financial
condition, results of operations and cash flows. A
 
                                       9
<PAGE>
significant barrier to on-line financial transactions is the secure transmission
of confidential information over public networks. We rely on encryption and
authentication technology to provide the security and authentication necessary
for secure transmission of confidential information. Advances in computer
capabilities, new discoveries in the field of cryptography or other developments
could result in a compromise or breach of the algorithms Net.B@nk and its
third-party service providers use to protect customer transaction data. See
"Business--Security."
 
    We are part of a rapidly evolving electronic commerce market. Market
acceptance of internet banking depends substantially on widespread adoption of
the internet for general commercial and financial services transactions. If
another provider of commercial services through the internet were to suffer
damage from a physical break-in, security breach or other disruptive problem
caused by the internet or other users, the growth and public acceptance of the
internet for commercial transactions could suffer. Such an event could deter
potential customers or cause customers to leave us and thereby materially
adversely affect our business, financial condition, results of operations and
cash flows.
 
INDUSTRY COMPETITION MAY ADVERSELY AFFECT OUR SUCCESS
 
    The banking industry is highly competitive in general, and the market for
internet banking in particular has experienced a recent surge in new entrants.
Our future profitability depends on our ability to compete successfully. We
believe our ability to compete successfully depends on a number of factors,
including:
 
    - Market presence;
 
    - Customer service and satisfaction;
 
    - The capacity, reliability and security of our network infrastructure;
 
    - Ease of access to and navigation of the internet;
 
    - Our competitors' interest rates and service fees;
 
    - The scope of our products and services and the rate at which we and our
      competitors introduce them; and
 
    - Industry and general economic trends.
 
    If we experience difficulty in any of these areas, our business, financial
condition, results of operations and cash flows could be materially adversely
affected.
 
    In addition, many of our principal competitors, traditional banks and
thrifts, other internet banks and other financial service providers, such as
brokerage and insurance companies, have greater financial and other resources
than we do. Because there are few barriers to on-line market entry for existing
chartered financial institutions, our competitors could implement internet
banking operations with relative ease. Furthermore, brokerage companies and
other financial service providers may not be subject to the same degree of
regulation as we are. See "Business--Competition."
 
FAILURE TO IMPLEMENT OUR BUSINESS STRATEGY OR MANAGE OUR GROWTH EFFECTIVELY MAY
  ADVERSELY AFFECT OUR FINANCIAL PERFORMANCE
 
    We may not succeed in implementing our business strategy and, even if we do
succeed, our strategy may not have the favorable impact on operations that we
anticipate. Our success depends on our ability to execute our marketing plan,
leverage our low cost structure, offer a broad array of products and services,
provide convenient, high-quality customer service and employ other elements of
our business strategy. We may not be able to manage effectively the expansion of
our operations or achieve the rapid execution necessary to exploit fully the
market for our services. If we are unable to manage growth effectively, or to
otherwise adequately implement our business strategy, our business,
 
                                       10
<PAGE>
financial condition, results of operations and cash flows could be materially
adversely affected. See "Business--Growth Strategy."
 
FAILURE TO INTRODUCE NEW PRODUCTS AND SERVICES SUCCESSFULLY MAY CAUSE US TO LOSE
  MARKET SHARE
 
    If we are unable to develop and bring additional products and services to
market in a timely manner, we could lose market share to competitors who are
able to offer these additional products and services, which could materially
adversely affect our business, financial condition, results of operations and
cash flows. Our success depends in part upon our ability to offer new products
and services that meet changing customer requirements. See "Business--Industry
Background," "--The Net.B@nk Solution" and "--Products and Services."
 
OUR PROFITABILITY AND GROWTH MAY BE ADVERSELY AFFECTED IF INTERNET BANKING DOES
  NOT BECOME WIDELY ACCEPTED
 
    If the internet banking market does not continue to develop, our business,
financial condition, results of operations and cash flows could be materially
adversely affected. The market for internet banking services is rapidly evolving
and the ultimate demand for and market acceptance of internet banking remains
uncertain. Market acceptance of internet banking depends on consumer willingness
to use the internet for general commercial and financial services transactions.
Other critical issues concerning the commercial use of the internet, including
reliability, cost, ease of use and access and quality of service, may also
impact the growth of internet use. Consequently, internet banking may not become
as widely accepted as traditional methods of banking and our profitability and
growth could be adversely affected. See "Business--Industry Background" and
"--The Net.B@nk Solution."
 
OUR COMPETITIVE POSITION DEPENDS ON OUR ABILITY TO ATTRACT AND RETAIN KEY
  PERSONNEL
 
    Our success depends upon the continued service of our senior management team
and key technical personnel and upon our ability to attract and retain qualified
personnel. If we lose the services of our key personnel, or are unable to
attract additional qualified personnel, our business, financial condition,
results of operations and cash flows could be materially adversely affected. On
April 30, 1999, Donald S. Shapleigh, Jr. resigned as our President. We have not
yet hired anyone to replace him and cannot predict when this position will be
filled. To date, this vacancy has not adversely affected our operations;
however, we cannot predict the effect a continued vacancy in this position will
have on our operations. Our employees do not have employment agreements and may
voluntarily terminate their employment at any time. In the current market,
competition for qualified employees, particularly in technical fields, is
intense. In our experience, it can take a significant period of time to identify
and hire personnel with the combination of skills and attributes required to
carry out our strategy. We do not carry key person life insurance on any of our
executives. See "Management."
 
CHANGES IN INTEREST RATES MAY DECREASE OUR NET INTEREST INCOME
 
    An increase or decrease in interest rates could have a material adverse
effect on our net interest income, capital and liquidity. Our operations depend
substantially on our net interest income, which is the difference between the
interest income earned on our interest-earning assets, such as loans and
investments, and the interest expense paid on our interest-bearing liabilities,
such as deposits and other borrowings. Like most depository institutions, our
earnings are affected by changes in market interest rates and other economic
factors beyond our control. While we intend to continue to take measures to
decrease interest rate risk, these measures may not be effective in minimizing
the exposure to interest rate risk. The difference between the amount of
interest-earning assets and interest-bearing liabilities that mature within a
given period of time, or the interest rate sensitivity "gap," indicates the
extent to which an institution's interest rate spread will be affected by
changes in interest rates. A gap is considered positive when the amount of
interest rate-sensitive assets exceeds the amount of interest
 
                                       11
<PAGE>
rate-sensitive liabilities and is considered negative when the amount of
interest rate-sensitive liabilities exceeds the amount of interest
rate-sensitive assets. In a rising interest rate environment, an institution
with a positive gap would be in a better position than an institution with a
negative gap to invest in higher yielding assets or have its asset yields
adjusted upward, which would result in the yield on its assets increasing at a
faster pace than the cost of its interest-bearing liabilities. During a period
of falling interest rates, however, an institution with a positive gap would
tend to have its assets maturing at a faster rate than one with a negative gap,
which would tend to reduce or restrain the growth of its net interest income. If
we are unsuccessful in managing interest rate fluctuations, our business,
financial condition, results of operations and cash flows could be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Market Risk."
 
OUR OPERATIONS COULD BE INTERRUPTED IF OUR THIRD-PARTY SERVICE PROVIDERS
  EXPERIENCE DIFFICULTY OR TERMINATE THEIR SERVICES
 
    If our third-party service providers experience difficulties or terminate
their services and we are unable to replace them with another service provider,
our operations could be interrupted. If an interruption were to continue for a
significant period of time, our business, financial condition, results of
operations and cash flows could be materially adversely affected. We depend, and
will continue to depend, significantly on a number of relationships with
third-party service providers. Specifically, we receive essential Web hosting,
electronic bill payment and core systems processing services on an outsourced
basis from NCR Corporation, CheckFree Corporation and BISYS Group, Inc.,
respectively. See "Business--Operations."
 
OUR COMPUTER SYSTEMS, AND THOSE OF OTHERS ON WHOM WE RELY, MAY NOT OPERATE
  PROPERLY ON YEAR 2000-SENSITIVE DATES
 
    The year 2000 issue common to most corporations, including Net.B@nk,
concerns the inability of some computer software programs and databases to
recognize the year 2000 and other year 2000-sensitive dates. Computer programs
we or our service providers use that recognize a date using "00" as the year
1900 rather than the year 2000 could result in errors or system failures that
could ultimately cause us or our service providers to be unable to process
customer transactions. This would require us to cease operations pending
resolution of the problem. We believe our principal risk lies in the potential
inability of our outside vendors and service providers to process date-sensitive
information involving the year 2000. We also face risks relating to the
potential year 2000 noncompliance of other institutions that service our loans,
merchants receiving electronic transfers of funds from our customers, the
FedWire system governing electronic funds transfers, the ATM networks with which
we are is affiliated and the Federal Reserve system itself. Additionally, if any
of our borrowers encounter year 2000 computer malfunctions they may become
unable to repay their loans.
 
    Furthermore, if we are unable to achieve year 2000 readiness, our regulators
could suspend our operations. Although we are working to resolve the potential
impact of the year 2000 on the ability of the computerized information systems
we use to accurately process information that may be date-sensitive, if we or
any of our service providers or other entities cannot achieve year 2000
readiness, our business, financial condition, results of operations and cash
flows could be materially adversely affected. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000."
 
THE NOTES WILL RANK BELOW OUR EXISTING AND FUTURE SENIOR INDEBTEDNESS AND WE MAY
  BE UNABLE TO REPAY OUR OBLIGATIONS UNDER THE NOTES
 
    The notes will be unsecured and subordinated in right of payment to all of
our existing and future Senior Indebtedness. The notes are effectively
subordinated to all existing and future liabilities of our
 
                                       12
<PAGE>
subsidiaries, including our banking subsidiary's obligations to its depositors
and to its trade and other creditors. Because the notes are subordinate to our
Senior Indebtedness, (1) in the event of our bankruptcy, liquidation or
reorganization, (2) upon the acceleration of the notes due to an event of
default under the notes indenture or (3) in certain other events described in
the notes indenture, we will make payments on the notes only after we have
satisfied all of our senior obligations. As a result, we may not have sufficient
assets remaining to pay amounts on any or all of the notes.
 
    The notes indenture does not limit our ability to incur other indebtedness
and liabilities. We may have difficulty paying our obligations under the notes
if we incur additional indebtedness or liabilities. As of March 31, 1999, before
giving effect to the use of proceeds from this notes offering and the concurrent
common stock offering, we had no Senior Indebtedness outstanding. At March 31,
1999, our banking subsidiary's liabilities, including deposits, were
approximately $383.0 million. We anticipate that from time to time we may incur
additional indebtedness, including Senior Indebtedness, which could adversely
affect our ability to pay our obligations under the notes.
 
WE MAY BE UNABLE TO REPURCHASE THE NOTES
 
    There is no sinking fund with respect to the notes, and at maturity the
entire outstanding principal amount of the notes will become due and payable by
Net.B@nk. If a Change of Control of Net.B@nk occurs, under certain circumstances
a holder of the notes may require that we repurchase all or a portion of its
notes. At maturity or if a Change of Control does occur, we might not have
sufficient funds or be able to arrange for additional financing to pay the
repurchase price for all the notes tendered to us or due at maturity. Future
borrowing arrangements or agreements relating to Senior Indebtedness to which we
become a party may contain restrictions on, or prohibitions against, our
repurchase of the notes. If the maturity date or a Change of Control occurs when
we are prohibited from repurchasing the notes, we could try to obtain the
consent of the lenders under those arrangements to purchase the notes or we
could attempt to refinance the borrowings that contain the restrictions. If we
do not obtain the necessary consents or refinance these borrowings, we will be
unable to repurchase the notes. In that case, our failure to repurchase any
tendered notes or notes due upon maturity would constitute an event of default
under the notes indenture. This could, in turn, cause a default under the terms
of our then existing Senior Indebtedness. As a result, in these circumstances,
the subordination provisions of the notes indenture would, absent a waiver,
prohibit any repurchase of the notes until we pay in full the senior debt.
 
THERE MAY BE NO PUBLIC MARKET FOR THE NOTES
 
    The notes will be a new issue of securities with no established trading
market. Although the underwriters for this notes offering have advised us that
they intend to make a market in the notes, they have no obligation to do so and
may discontinue their market making at any time without notice. In addition,
their market making activity will be subject to limits imposed under the federal
securities laws. Accordingly, a market for the notes may not develop and, if it
does develop, it may not be maintained. Various factors could have a material
adverse effect on the trading price of the notes, including (1) the failure of
an active market to develop and (2) fluctuations in prevailing interest rates.
In addition, our operating results and prospects could from time to time fall
below the expectations of public market analysts and investors, which could
adversely affect public perception of our creditworthiness and therefore the
trading price of the notes.
 
THE MARKET PRICE OF OUR COMMON STOCK HAS FLUCTUATED, AND COULD FLUCTUATE
  SIGNIFICANTLY IN THE FUTURE
 
    The market price of our common stock has been highly volatile since our
initial public offering, with closing prices ranging from a low of $2.92 per
share to a high of $78.34 per share. The market price of the common stock will
continue to fluctuate, and could fluctuate significantly, in response to various
factors and events, including the liquidity of the market for the common stock,
differences
 
                                       13
<PAGE>
between our actual financial or operating results and those expected by
investors and analysts, changes in analysts' recommendations or projections, new
statutes or regulations or changes in the interpretation of existing statutes
and regulations affecting our business, changes in general economic or market
conditions and broad market fluctuations. See "Price Range of Common Stock."
 
WE RELY ON INTELLECTUAL PROPERTY RIGHTS
 
    We regard the form and substance of our name as proprietary and attempt to
protect it by relying on intellectual property laws. We have submitted a United
States trademark registration for the Net.B@nk name and take active measures to
safeguard this name. Policing unauthorized use of proprietary information is
difficult, however, and we cannot assure you about the continued viability or
value of any of the intellectual property rights that we now have or may have in
the future. Litigation may be necessary in the future to enforce our
intellectual property rights.
 
    In addition, our business activities could infringe upon the proprietary
rights of others, and other parties could assert infringement claims against us.
Any litigation claims or counterclaims we might make could impair our business
because they could be time-consuming, result in costly litigation or divert
management's attention.
 
    We own the internet domain name "netbank.com". The regulation of domain
names in the United States and in foreign countries may change. Regulatory
bodies could establish additional top-level domains, appoint additional domain
name registrars or modify the requirements for holding domain names, any or all
of which may dilute the strength of our name. We may not acquire or maintain our
domain names in all of the countries in which our Web site may be accessed or
for any or all of the top-level domain names that may be introduced. The
relationship between regulations governing domain names and laws protecting
intellectual property rights is unclear. Therefore, we may not be able to
prevent third parties from acquiring domain names that infringe or otherwise
decrease the value of our trademarks and other intellectual property rights.
 
GOVERNMENT REGULATION MAY ADVERSELY AFFECT OUR ABILITY TO CONDUCT BUSINESS
 
    BANK REGULATION.  Revisions to existing or adoption of new laws or
regulations could subject us to more demanding regulatory compliance
requirements and could adversely affect our ability to conduct, or our cost of
conducting, business. Net.B@nk, Inc., the parent company, is regulated by the
Office of Thrift Supervision and the Georgia Department of Banking and Finance
and subject to certain restrictions imposed by the Board of Governors of the
Federal Reserve System. Net.B@nk, our banking subsidiary, is regulated by the
Office of Thrift Supervision and the FDIC. We are also subject to various laws
and regulations relating to commercial and consumer transactions generally, such
as the Uniform Commercial Code, as well as the electronic funds transfer rules
which are contained in Regulation E, issued by the Federal Reserve Board. Any of
these agencies, or other governmental or regulatory authorities, could revise
existing regulations or adopt new regulations at any time. Legislation and
regulatory initiatives containing wide-ranging proposals for altering the
structure, regulation and competitive relationships of financial institutions
are introduced regularly. We cannot predict whether or in what form a proposed
statute or regulation will be adopted or the extent to which it may affect our
business.
 
    Furthermore, given the rapid expansion of the electronic commerce market,
many regulatory bodies are adopting measures to ensure that their regulations
are keeping pace. For example, Congress has held hearings on whether to regulate
the electronic commerce market, while numerous states are considering adopting
their own laws to regulate internet banking. Furthermore, bank regulators are
considering proposing new laws relating to customer privacy. If enacted, these
laws, rules and regulations could force us to comply with more complex and
perhaps more burdensome regulatory
 
                                       14
<PAGE>
requirements, which could materially adversely affect our business, financial
condition, results of operations and cash flows. See "Business--Supervision and
Regulation."
 
    INTERNET REGULATION.  Our ability to conduct, and/or our cost of conducting,
business may also be adversely affected by a number of legislative and
regulatory proposals concerning other aspects of the internet, which are
currently under consideration by federal, state, local and foreign governmental
organizations. These proposals include, but are not limited to the following
matters: on-line content, user privacy, taxation, access charges, liability of
third-party activities and jurisdiction. Moreover, we do not know how existing
laws relating to these issues will be applied to the internet. The adoption of
new laws or the application of existing laws could decrease the growth in the
use of the internet, which could in turn decrease the demand for our products
and services, increase our cost of doing business or otherwise have a material
adverse effect on our business, financial condition, results of operations and
cash flows. Furthermore, government restrictions on internet content could slow
the growth of internet use and decrease acceptance of the internet as a
communications and commercial medium and thereby have a material adverse effect
on our business, financial condition and results of operations.
 
    Some local telephone carriers have asserted that the growing popularity and
use of the internet has burdened the existing telecommunications infrastructure
and caused interruptions in telephone service in areas with high internet use.
These carriers have petitioned the Federal Communications Commission to impose
access fees on internet service providers and commercial on-line service
providers. If the Federal Communications Commission imposes access fees, the
costs of transacting business over the internet could increase substantially,
potentially slowing the growth in use of the internet. This could in turn
decrease demand for our services or increase our cost of doing business, and
thus have a material adverse effect on our business, financial condition,
results of operations and cash flows.
 
    INTERNET PRIVACY.  Internet user privacy has become an issue both in the
United States and abroad. The Federal Trade Commission has proposed model
legislation that would force companies to comply with specified core information
practices. It is possible that Congress could adopt either legislation similar
to that proposed by the Federal Trade Commission or other privacy legislation
that could have a material adverse effect on the way in which we are allowed to
conduct our business, especially those aspects that involve the collection or
use of personal information. At the international level, the European Union has
adopted a directive that permits European Union member countries to impose
restrictions on the collection and use of personal data. This directive could,
among other things, affect United States companies that collect information over
the internet from individuals in European Union member countries and may impose
restrictions that are more stringent than current internet privacy standards in
the United States. In response to this directive, on November 4, 1998, the
United States Department of Commerce published for comment a set of safe harbor
principles regarding privacy protection for personally identifiable data. These
principles were revised on April 19, 1999.
 
OUR DIRECTORS AND EXECUTIVE OFFICERS OWN A SIGNIFICANT PORTION OF OUR
  OUTSTANDING COMMON STOCK AND COULD EXERCISE SIGNIFICANT INFLUENCE OVER
  NET.B@NK
 
    As of April 30, 1999, our directors and executive officers beneficially
owned 5,384,096 shares, representing approximately 20.0%, of the outstanding
common stock of Net.B@nk. As a result, our directors and executive officers
could exercise significant influence over matters requiring shareholder
approval, including the election of directors or a change in control of
Net.B@nk. See "Management" and "Principal Shareholders."
 
                                       15
<PAGE>
OUR ARTICLES OF INCORPORATION AND BYLAWS COULD DETER A CHANGE IN CONTROL AND
  DEPRIVE YOU OF AN OPPORTUNITY TO SELL YOUR COMMON STOCK UNDERLYING THE NOTES
  AT A PREMIUM OVER MARKET PRICES
 
    Our Articles of Incorporation and Bylaws contain provisions that may deter
an attempt to change or gain control of Net.B@nk. As a result, you may be
deprived of opportunities to sell some or all of your shares of the common stock
underlying the notes at prices that represent a premium over market prices.
These provisions include the existence of blank check preferred stock, staggered
terms for the directors, restrictions on the ability to change the number of
directors or to remove a director and supermajority voting requirements.
 
WE DO NOT INTEND TO PAY CASH DIVIDENDS
 
    We do not intend to pay cash dividends in the foreseeable future, as we
expect to apply any earnings to developing and expanding our business. See
"Dividend Policy."
 
THE MARKET PRICE OF THE COMMON STOCK MAY DECLINE DUE TO SHARES ELIGIBLE FOR
  FUTURE SALE
 
    Future sales of substantial amounts of common stock in the public market or
the perception that such sales could occur could adversely affect the market
price of the common stock. Certain directors and executive officers of Net.B@nk,
who collectively hold 5,172,096 restricted shares of common stock, are precluded
under Office of Thrift Supervision requirements from selling any of these shares
of common stock without prior Office of Thrift Supervision approval until July
28, 2000. If all of these shares are sold when they first become eligible for
resale, the increase in the number of shares available for sale could adversely
affect the market price of the common stock.
 
WE HAVE BROAD DISCRETION IN ALLOCATING THE NET PROCEEDS FROM THIS OFFERING
 
    Our management will have broad discretion in allocating the net proceeds
from this offering. We have not yet determined the allocation of these funds to
the various purposes described in this prospectus. See "Use of Proceeds."

                         CAUTIONARY STATEMENT REGARDING
                           FORWARD-LOOKING STATEMENTS
 
    Some of the statements in this prospectus are forward-looking statements.
These forward-looking statements include statements in the "Business-Industry
Background" and "The Net.B@nk Solution" sections of this prospectus relating to
trends in internet use and electronic commerce. These forward-looking statements
also include statements relating to our performance in the "Management's
Discussion and Analysis of Financial Condition and Results of Operations," "Use
of Proceeds" and "Business" sections of this prospectus. In addition, we may
make forward-looking statements in future filings with the Securities and
Exchange Commission and in written materials, press releases and oral statements
issued by us or on our behalf. Forward-looking statements include statements
regarding the intent, belief or current expectations of Net.B@nk or its officers
and can be identified by the use of forward-looking terms such as "may," "will,"
"should," "believe," "expect," "anticipate," "estimate," "continue" or the
negative of these words or comparable terminology. Forward-looking statements
relating to the following involve inherent risks and uncertainties:
 
    - The growth in the use of the internet;
 
    - Our business strategy;
 
    - Competitiveness in the banking industry;
 
    - Potential regulatory obligations; and
 
    - Other statements that are not historical facts.
 
    Our actual results could differ materially from those anticipated from the
forward-looking statements, depending on various important factors. These
factors include:
 
    - A possible decline in asset quality;
 
    - The evolving nature of the market for internet banking;
 
    - The possible adverse effects of unexpected changes in the interest rate
      environment; and
 
    - Increasing competition and regulatory changes.
 
    In addition, please note that matters set forth under the caption "Risk
Factors" constitute cautionary statements identifying important factors with
respect to the forward-looking statements, including risks and uncertainties,
that could cause actual results to differ materially from those in the
forward-looking statements.
 
    All forward-looking statements in this prospectus are based on information
available to us as of the date of this prospectus. We do not undertake to update
any forward-looking statements that may be made by us or on our behalf in this
prospectus or otherwise.

                                USE OF PROCEEDS
 
    We estimate that we will receive net proceeds from the sale of the notes of
approximately $96,710,000. If the underwriters exercise their over-allotment
option in full, $115,000,000 aggregate principal amount of the notes would be
sold by us, resulting in net proceeds of $111,260,000.
 
    We intend to invest the majority of the net proceeds from this notes
offering in earning assets, including purchased loan portfolios, new loans that
we originate and investment securities. We intend to use the earnings from these
assets and the balance of the net proceeds from this offering for general
corporate purposes, including increasing our budgeted marketing efforts to $11.0
million for the next twelve months. We also intend to hire additional personnel,
to fund other costs related to our accelerated deposit growth and to pursue
strategic partnerships and investments. We have not yet allocated the net
proceeds to each of the proposed purposes. Although we continually evaluate
opportunities for strategic partnerships and investments, we do not presently
have an understanding or agreement relating to any such arrangement that is
material to our business or that we have not otherwise disclosed in this
prospectus.
 
    Concurrent with this offering and by means of a separate prospectus, we are
offering 3,000,000 shares of our common stock. We estimate that the net proceeds
to us from the sale of this common stock, after payment of underwriting
discounts and commissions and estimated expenses of the offering, will be
$176,200,000, assuming an offering price of $62.00 per share. If the
underwriters exercise their over-allotment option in full, we estimate that the
net proceeds to us will be $202,705,000 after payment of underwriting discounts
and commissions and estimated expenses of the offering. The completion of the
common stock offering and this notes offering do not depend on one another. We
intend to use the proceeds from the common stock offering for the same purposes
as for the notes offering.

    The pro forma capitalization as adjusted to reflect this offering assumes
the offering of $100,000,000 aggregate principal amount of notes. The estimated
underwriting discounts and commissions and other fees and expenses related to
the notes are expected to total $3,290,000. If the underwriters exercise their
over-allotment option in full, $115,000,000 aggregate principal amount of notes
would be sold by us, resulting in total net proceeds of $111,260,000.
    
 
   
    The pro forma capitalization as further adjusted to reflect the common
offering again assumes the offering of $100,000,000 aggregate principal amount
of notes, assuming no conversion of the notes and in addition, assumes that the
net proceeds from the common stock offering, after deducting the estimated
underwriting discounts and commissions and estimated offering expenses payable
by us, are $176,200,000, assuming an offering price of $62.00 per share. If the
underwriters exercise their over-allotment option in full, 3,450,000 shares of
common stock would be sold by us, resulting in total net proceeds of
$202,705,000.

- ------------------------------
(1) On April 13, 1999, we declared a 3 for 1 split of our common stock to be
    effected in the form of a stock dividend payable on May 14, 1999 to
    shareholders of record as of the close of business on April 23, 1999. All
    references to share and per share amounts have been retroactively adjusted
    to reflect this split.
(2) Assuming no income tax benefit and assuming a statutory income tax rate of
    34% for the year, pro forma net income per common and potential common share
    for the year ended December 31, 1998 would have been $0.03 per share, basic,
    and $0.02 per share, diluted.
(3) For purposes of computing this ratio, earnings available for fixed charges

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
    Net.B@nk, Inc. is a holding company that wholly owns Net.B@nk, a federal
savings bank. Net.B@nk, Inc. was incorporated as a Georgia corporation on
February 20, 1996, for the purpose of forming and, ultimately, operating a
wholly owned federal savings bank subsidiary. During the period from February
20, 1996 to July 31, 1997, pending regulatory approval and the acquisition of a
bank charter, we operated as a development stage enterprise under an agreement
with Carolina First Bank, a wholly owned subsidiary of Carolina First
Corporation. Carolina First Bank agreed to hold and service the deposit accounts
we generated in exchange for 3,975,000 shares of common stock, which were valued
at $3.8 million. In addition, during the period from February 20, 1996 to July
31, 1997, we were a party to an agreement with First Alliance/Premier
Bancshares, Inc. pursuant to which we agreed to purchase the charter of First
Alliance's subsidiary, Premier Bank, $5.0 million in loans, $5.0 million in
certificates of deposit and $2.0 million in unimpaired capital in exchange for
$2.2 million in cash, 124,218 shares of the common stock valued at $125,000 and
$75,000 in additional cash for reimbursement of direct out-of-pocket expenses.
On July 11, 1997, we received final regulatory approval from the Office of
Thrift Supervision to purchase the bank charter from First Alliance. On July 31,
1997, we received approximately $38.4 million in net proceeds from the sale of
10,500,000 shares of our common stock in our initial public offering and
consummated our agreements with both First Alliance and Carolina First Bank. As
a result, Net.B@nk became a wholly owned subsidiary of Net.B@nk, Inc. As of
March 31, 1999, we had 24,634 accounts and approximately $332.7 million in
deposits.
 
    On April 13, 1999, we declared a 3 for 1 split of our common stock effected
in the form of a stock dividend payable on May 14, 1999 to shareholders of
record as of the close of business on April 23, 1999. All references to share
and per share amounts have been retroactively adjusted to reflect this split.
 
FINANCIAL CONDITION
 
    Our assets were $526.5 million at March 31, 1999 compared to $388.4 million
and $93.2 million at December 31, 1998 and 1997, respectively. The increase of
$138.1 million from December 31, 1998 to March 31, 1999 was primarily the result
of approximately $105.0 million of net proceeds we received from an offering of
common stock in February 1999, as well as an increase in customer deposits of
approximately $49.1 million. We are using the proceeds from both the February
1999 offering of common stock and the increase in customer deposits for our
widespread marketing campaign to increase public awareness of the Net.B@nk name
and our products and services, and investing the excess in federal funds sold,
investment securities and loans.
 
    The increase in assets of $295.2 million from December 31, 1997 to December
31, 1998 was primarily due to growth in our loan portfolio resulting from our
purchase of approximately $257.5 million in home equity loans and first and
second mortgage loans and the purchase of approximately $41.4 million in
investment securities during the year ended December 31, 1998. In addition, we
recorded a $2.3 million deferred tax asset related primarily to previous net
operating loss carryforwards that we expect to realize for tax purposes. Because
we achieved profitability in 1998, we believe that it is more likely than not
that our deferred tax assets will be realized. We also had loan sale proceeds
receivable of $23.2 million related to loan origination agreements with third
parties at December 31, 1998.
 
    Total liabilities increased $33.0 million from $349.7 million at December
31, 1998 to $382.7 million at March 31, 1999. This increase was primarily due to
the rapid growth in our deposit portfolio of $49.1 million as a result of our
marketing campaign, offset by a $15.0 million decrease in other borrowed funds.
Total liabilities increased $290.6 million from $59.1 million at December 31,
1997 to
 
                                       22
<PAGE>
$349.7 million at December 31, 1998. This increase was primarily due to the
rapid growth of our deposit portfolio as a result of marketing programs we
introduced in the fourth quarter of 1997.
 
    Total shareholders' equity increased $105.0 million from December 31, 1998
to March 31, 1999 primarily due to our receipt of approximately $105.0 million
from the sale of 7,290,000 shares of our common stock in a public offering.
Total shareholders' equity increased $4.6 million from December 31, 1997 to
December 31, 1998 as a result of net income of $4.5 million and comprehensive
income of $82,000.

1998.

RESULTS OF OPERATIONS
 
THREE MONTHS ENDED MARCH 31, 1999 COMPARED TO THREE MONTHS ENDED MARCH 31, 1998
 
    GENERAL.  Net income for the three months ended March 31, 1999 amounted to
$692,000, an increase of $843,000 compared to a $151,000 loss for the three
months ended March 31, 1998. The increase in net income was the result of the
growth of our operations from 1998 to 1999.
 
    INTEREST INCOME.  Interest income related to our loan and investment
portfolio for the three months ended March 31, 1999 was $7.6 million compared to
$2.2 million for the three months ended March 31, 1998. The increase in interest
income was a result of the growth of our loan portfolio of $258.3 million from
March 31, 1998 to March 31, 1999, offset partially by a decrease in the average
yield on loans from 8.02% for the three months ended March 31, 1998 to 7.55% for
the three months ended March 31, 1999. In addition, the investment portfolio
grew from $46.3 million at March 31, 1998 to $80.3 million at March 31, 1999.
The yield on the investment portfolio was 5.63% for the three months ended March
31, 1998 compared to 6.20% for the three months ended March 31, 1999.
 
    INTEREST EXPENSE.  For the three months ended March 31, 1999, we recorded
$4.0 million in interest expense on deposits compared to $1.3 million for the
three months ended March 31, 1998 as a result of our increase in customer
deposits from $128.7 million at March 31, 1998 to $332.7 million at March 31,
1999. In addition, interest paid on deposits decreased from 5.54% for the three
months ended March 31, 1998 to 5.29% for the three months ended March 31, 1999.
Also, during the three months ended March 31, 1999, we recorded approximately
$500,000 in interest expense associated with short-term borrowings under our
line of credit agreements and advances from the Federal Home Loan Bank.
 
    NET INTEREST INCOME.  Net interest income is determined by our interest rate
spread, which is the difference between the yields earned on our
interest-earning assets and the rates paid on our interest-bearing liabilities,
and the relative amounts of interest-earning assets and interest-bearing
liabilities. Net interest income was $3.0 million for the three months ended
March 31, 1999 compared to $903,000 for the three months ended March 31, 1998.
The increase in net interest income resulted from the increase in the amount of
loans and deposits from March 31, 1998 to March 31, 1999.
 
    PROVISION FOR LOAN LOSSES.  In connection with the purchase of loan
portfolios, we assess the inherent loss in the portfolios and record the
necessary allowance by adjusting the premium associated with each portfolio.
During the three months ended March 31, 1999, we recorded $1.2 million as an
addition to premiums related to allowance for loan losses for loans purchased
during the quarter. In addition, we also recorded a provision for loan losses of
$49,800 related primarily to a decline in credit quality of a specific pool of
automobile loans. This compared to a provision of $4,000 recorded during the
three months ended March 31, 1998. We periodically review the performance of our
loan portfolio by reviewing charge-offs, delinquency statistics and industry
statistics on a pool by pool basis for our purchased portfolio and a loan by
loan basis for our originated loans. If we note a decline in credit quality for
a specific pool or loan, we record an additional allowance through a charge to
the provision for loan losses. We maintain the allowance for loan losses at a
level that we estimate to be adequate to provide for probable losses in the loan
portfolio. We determine the adequacy of the allowance based upon reviews of
individual loans, recent loss experience, current economic conditions, the risk
characteristics of the various categories of loans and other pertinent factors.
 
    NONINTEREST INCOME.  For the three months ended March 31, 1999, we recorded
approximately $246,000 in loan and deposit service charges and fees compared to
$123,000 recorded during the three months ended March 31, 1998. The significant
increase in service charges was a result of a significant increase in both the
loan and deposit portfolios.

    NONINTEREST EXPENSES.  Noninterest expenses include all operating expenses,
including salaries and benefits, marketing, general and administrative expenses
(excluding interest expense, provision for loan losses and income taxes).
Noninterest expense increased 83%, or $1.0 million, for the three months ended
March 31, 1999 compared to the three months ended March 31, 1998. This increase
was primarily the result of increases in salaries and benefits, customer service
and data processing as we added additional employees and operational activities
to support additional customers, and an increase in marketing expense as we
expanded our marketing programs to build public awareness of the Net.B@nk name
and our products and services.
 
YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997
 
    GENERAL.  Net income for the year ended December 31, 1998 amounted to $4.5
million, an increase of $10.1 million compared to the $5.6 million loss for the
year ended December 31, 1997. The statement of operations for the year ended
December 31, 1997 reflects our operations before and immediately following the
acquisition of our bank charter. Because we did not acquire the charter until
July 31, 1997, we had no earning assets prior to that date. A substantial
portion of the income for the year ended December 31, 1998 resulted from the
recognition of $2.3 million in tax benefits. The benefits resulted from the
reversal of a valuation allowance of $3.3 million previously associated with our
deferred tax assets offset by income tax expense for the year ended December 31,
1998. Because we achieved profitability during 1998, we now believe it is more
likely than not that the deferred tax assets will be realized.
 
    INTEREST INCOME.  Interest income related to our loan and investment
portfolio for the year ended December 31, 1998 was $18.1 million compared to
$2.2 million for the year ended December 31, 1997. The increase is a result of
the growth of our loan portfolio from $44.9 million at December 31, 1997 to
$280.4 million at December 31, 1998 offset by a decrease in average yield from
8.70% for the year ended December 31, 1997 to 7.97% for the year ended December
31, 1998. In addition, the investment security portfolio grew from $18.1 million
at December 31, 1997 to $59.5 million at December 31, 1998 as we invested cash
received from customer deposits. The yield on the investment portfolio was 7.06%
for the year ended December 31, 1997 compared to 6.01% for the year ended
December 31, 1998.
 
    INTEREST EXPENSE.  For the year ended December 31, 1998, we recorded $10.2
million in interest expense on deposits as a result of our increase in customer
deposits from $58.7 million at December 31, 1997 to $283.6 million at December
31, 1998. In addition, the average interest rate paid on deposits increased from
5.17% for the year ended December 31, 1997 to 5.77% for the year ended December
31, 1998. We recorded interest expense on deposits of $1.3 million during the
year ended December 31, 1997 as we transferred our deposits to our banking
subsidiary from Carolina First Bank and began paying interest on those deposits.
In addition, during the year ended December 31, 1998, we recorded approximately
$1.2 million of interest expense associated with other borrowed funds under our
line of credit agreements and Federal Home Loan Bank advances.
 
    NET INTEREST INCOME.  Net interest income is determined by our interest rate
spread, which is the difference between the yields earned on our
interest-earning assets and the rates paid on our interest-bearing liabilities,
and the relative amounts of interest-earning assets and interest-bearing
liabilities. With the growth in our operations, net interest income increased to
$6.7 million for the year ended December 31, 1998, compared to $963,000 for the
year ended December 31, 1997.
 
    PROVISION FOR LOAN LOSSES.  During 1998, we recorded $3.6 million as an
addition to premium related to allowance for loan losses for purchased loans. In
addition, we recorded a $20,000 provision for loan losses for the year ended
December 31, 1998, compared to $472,000 recorded during the year ended December
31, 1997 for declines in credit quality on a specific pool of automobile loans
and additional allowance related to originated loans.
 
                                       26
<PAGE>
    NONINTEREST INCOME.  For the year ended December 31, 1998, we recorded
approximately $683,000 in loan and deposit service charges and fees compared to
$63,000 recorded during the year ended December 31, 1997. The significant
increase in service charges was driven by the significant increase in both the
loan and deposit portfolios.
 
    NONINTEREST EXPENSES.  Noninterest expenses decreased approximately $944,000
for the year ended December 31, 1998 compared to the year ended December 31,
1997. The primary component of the decrease during the year ended December 31,
1998 was a $1.4 million decrease in the amortization of the service contract
with Carolina First Bank as the service contract was fully amortized during the
second quarter of 1997. In addition, salaries and benefits decreased $1.0
million as we outsourced certain services and paid $450,000 of bonuses to our
employees upon completion of our initial public offering in July 1997. These
decreases were partially offset by increases in marketing, customer service,
data processing, occupancy and other expenses as we moved to our new offices and
began soliciting and serving new deposit customers.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO THE PERIOD FROM FEBRUARY 20, 1996 TO
  DECEMBER 31, 1996
 
    GENERAL.  We did not have any earning assets until July 31, 1997, when we
acquired our bank charter. The net loss for the year ended December 31, 1997 was
$5.6 million, an increase of $1.8 million when compared to the period from
February 20, 1996 to December 31, 1996. The statement of operations for the
period from February 20, 1996 to December 31, 1996 reflects the initial phase of
our operations, including the acquisition, testing and implementation of the
internet banking platform, marketing expenses and the accrual of Carolina First
Bank's expense reimbursements. Under the servicing agreement with Carolina First
Bank, customer deposits and the related assets resulting from our marketing
efforts, which began in August 1996, were included in Carolina First Bank's
financial operations.
 
    INTEREST INCOME.  Interest income for the year ended December 31, 1997 was
$2.2 million. We did not record a significant amount of interest income for the
period from February 20, 1996 to December 31, 1996 because we had no investments
or loans during that period. On July 31, 1997, we received the net proceeds from
our initial public offering and customer deposits held by Carolina First Bank
and invested those funds in federal funds, mortgage-backed securities and loans
purchased from Carolina First Bank and an independent third party.
 
    INTEREST EXPENSE.  Because we did not begin soliciting deposit accounts
until October 1996, we did not record any interest expense for the period from
February 20, 1996 to December 31, 1996. On July 31, 1997, based on the terms of
the servicing agreement with Carolina First Bank and the charter purchase
agreement, Carolina First Bank and First Alliance transferred approximately
$47.8 million in customer deposits and related assets to Net.B@nk. We recorded
approximately $1.3 million of interest expense during the year ended December
31, 1997. This amount includes $163,479 of net interest expense, which
represents the difference between interest expense paid to customers and
interest income paid to Net.B@nk by Carolina First Bank at the contractual rates
in the servicing agreement prior to July 31, 1997.
 
    NET INTEREST INCOME.  Net interest income is determined by our interest rate
spread, which is the difference between the yields earned on our
interest-earning assets and the rates paid on our interest-bearing liabilities,
and the relative amounts of interest-earning assets and interest-bearing
liabilities. Net interest income was $963,000 for the year ended December 31,
1997. Because we did not receive our bank charter until July 31, 1997, we were
not allowed to hold investments, loans or customer deposits during the period
from February 20, 1996 to December 31, 1996, and therefore, no significant
amount of net interest income was recorded for the period from February 20, 1996
to December 31, 1996.
 
                                       27
<PAGE>
    PROVISION FOR LOAN LOSSES.  We purchased our first loans during the period
from July 31, 1997 to December 31, 1997. During this period, we recorded a
provision for loan losses of $472,000 for a decline in credit quality related to
a specific pool of automobile loans and an additional allowance related to
originated loans.
 
    NONINTEREST INCOME.  For the period from July 31, 1997 to December 31, 1997,
we recorded approximately $63,000 in loan and deposit service charges and fees.
We recorded only miscellaneous management fees received of $60,000 during the
period from February 20, 1996 to December 31, 1996.
 
    NONINTEREST EXPENSES.  Noninterest expenses increased $2.2 million from $3.9
million during the period from February 20, 1996 to December 31, 1996 to $6.1
million for the year ended December 31, 1997. The primary components of the
increase were an increase of $1.6 million in salaries and benefits, which
reflects the payment of approximately $450,000 in bonuses to employees; the
amortization of approximately $343,000 in stock plan expense; increases of
$305,000, $391,000 and $236,000 in customer service, data processing and
marketing, respectively, reflecting the growth of our deposit base and related
support functions; and an increase of approximately $260,000 in other operating
expenses consisting primarily of legal and accounting fees. These increases were
offset by a $960,000 decrease in the amortization of the service contract with
Carolina First Bank as the service contract was fully amortized during the
second quarter of 1997. The expenses for the period from February 20, 1996 to
December 31, 1996 reflect only the initial phase of our operations, including
the acquisition, testing and implementation of our internet banking platform,
marketing expenses and the accrual of Carolina First Bank's expense
reimbursements.
 
STOCK OPTIONS
 
    Our 1996 Stock Incentive Plan authorizes us to grant to our key employees,
officers, directors and consultants nonqualified and incentive stock options to

of our common stock or cash awards. The total number of shares reserved for
issuance under the Stock Incentive Plan, as amended, is 3,750,000. Generally,
the options expire ten years from the date of the grant. A summary of the status
of the options granted under the Stock Incentive Plan as of December 31, 1996,
1997 and 1998 and the activity during such periods follows:

    In connection with the issuance of some of the options during the year ended
December 31, 1997, we will recognize $390,484 of compensation expense over the
vesting period. Certain of those options vested immediately on July 28, 1997,
upon completion of the initial public offering, and we recognized $319,704 of
unamortized compensation expense. The other options vest one-third on the first
anniversary of the date of issuance, one-third on the second anniversary of the
date of issuance and one-third on the third anniversary of the date of issuance.
Of the vested options, 708,423 cannot be exercised and sold until July 28, 2000
in accordance with an agreement signed with the Office of Thrift Supervision. Of
the 1,597,152 options outstanding as of December 31, 1998, 837,063 were

1,500 incentive stock options with an exercise price of $5.25 and $1.21,
respectively were exercised.
 
MARKET RISK
 
    ASSET AND LIABILITY MANAGEMENT.  Our principal business is the originating
and purchasing of loans, funded by customer deposits and, to the extent
necessary, other borrowed funds. Consequently, a significant portion of our
assets and liabilities are monetary in nature and fluctuations in interest
rates, specifically the prime rate, will affect our future net interest income
and cash flows. This interest rate risk is our primary market risk exposure. We
do not enter into derivative financial instruments such as futures, forwards,
swaps and options. Also, we have no market risk-sensitive instruments held for
trading purposes. Our exposure to market risk is reviewed on a regular basis by
our management.
 
    The following table sets forth the interest rate risk of our assets and
liabilities as of December 31, 1997.

    We measure interest rate sensitivity as the difference between the amount of
interest-earning assets and interest-bearing liabilities that mature within a
given period of time. The difference, or the interest rate sensitivity "gap,"
provides an indication of the extent to which an institution's interest rate
spread will be affected by changes in interest rates. The above table does not
consider interest rate adjustments on our adjustable rate loans. A gap is
considered positive when the amount of interest-rate sensitive assets exceeds
the amount of interest-rate sensitive liabilities and is considered negative
when the amount of interest-rate sensitive liabilities exceeds the amount of
interest-rate sensitive assets. In a rising interest rate environment, an
institution with a positive gap would be in a better position than an
institution with a negative gap to invest in higher yielding assets or have its
asset yields adjusted upward, which would result in the yield on its assets
increasing at a faster pace than the cost of its interest-bearing liabilities.
During a period of falling interest rates, however, an institution with a
positive gap would tend to have its assets maturing at a faster rate than one
with a negative gap, which would tend to reduce or restrain the growth of its
net interest income.
 
LENDING ACTIVITIES
 
    GENERAL.  At March 31, 1999, our loans receivable portfolio totaled $364.1
million or 69.2% of total assets. At December 31, 1998 and 1997, our loans
receivable portfolio totaled $280.4 million and $44.9 million, or 72.2% and

    A savings institution generally may not make loans to one borrower and
related entities in an amount which exceeds 15% of its unimpaired capital and
surplus, although loans in an amount equal to an additional 10% of unimpaired
capital and surplus may be made to a borrower and its related entities if the
loans are fully secured by readily marketable securities. At March 31, 1999, our
limit on loans to one borrower was approximately $21.6 million (15% unimpaired
capital and surplus). At March 31, 1999, we had not made any loans to any one
borrower, including persons or entities related to the borrower, exceeding the
limitation.

    ASSET QUALITY AND NONPERFORMING ASSETS.  During the years ended December 31,
1998 and 1997 and the three months ended March 31, 1999, we did not have any
significant loans on nonaccrual status, significant loans past due 90 days or
more or restructured loans.
 
    CONCENTRATIONS OF CREDIT RISK.  At December 31, 1998, a majority of our
loans were with customers residing in the Western and Southeastern United
States. At December 31, 1997, all of our loans were with customers residing in
the Southeastern United States.
 
    ALLOWANCE FOR LOAN LOSSES.  The allowance for loan losses is maintained at a
level management considers adequate to provide for probable losses in the loan
portfolio. As the majority of our portfolio is purchased, we make an estimate of
the loss inherent in the purchased portfolio based on industry statistics and
record an allowance for loan losses by adjusting the premium associated with the
purchased loans. We periodically review the adequacy of the allowance based upon
reviews of individual loans and loan pools, recent loss experience, current
economic conditions, the risk characteristics of the various pools of loans, or
individual loans, industry statistics and other pertinent factors. If we note a
decline in credit quality for a specific loan pool or a loan, we record an
additional allowance through a charge to the provision for loan losses. Loans
that we deem uncollectible are charged to the allowance. We also add provisions
for loan losses and recoveries on loans previously charged off to the allowance.
 
    Although we use the best information available to make determinations with
respect to the provisions for loan losses, additional provisions for loan losses
may be necessary in the future should economic or other conditions change
substantially. In addition, the Office of Thrift Supervision, as an integral
part of the examination process, periodically reviews our allowance for loan
losses. The agency may require us to recognize additions to the allowance based
on their judgments about the information available to them at the time of their
examination.
 
    The following table sets forth an analysis of our allowance for loan losses
during the years ended December 31, 1997 and 1998:

    INVESTMENT SECURITIES.  Our investment policy, as established by the Board
of Directors, is designed primarily to provide and maintain liquidity and to
generate a favorable return on investments without incurring undue interest rate
risk, credit risk and investment portfolio asset concentrations. Our investment
policy is currently implemented by the investment committee within the
parameters set by the Board of Directors.
 
    We are authorized to invest in obligations issued or fully guaranteed by the
United States government, certain federal agency obligations, certain time
deposits, negotiable certificates of deposit issued by commercial banks and
other insured financial institutions, investment grade corporate debt securities
and other specified investments.
 
    Securities classified as available for sale are reported at fair value, with
unrealized gains and losses, net of tax, excluded from earnings and reported in
other comprehensive income. At March 31, 1999 and December 31, 1998 and 1997,
all of our investment securities were classified as available for sale. At March
31, 1999 and December 31, 1998 and 1997, investments in the debt and/or equity
securities of any one issuer did not exceed more than 10% of our shareholders'
equity.
 
    The following tables set forth certain information relating to our
available-for-sale securities at December 31, 1997 and 1998 and March 31, 1999:

SOURCES OF FUNDS
 
    GENERAL.  Our primary sources of funds are deposits, borrowings, prepayments
and maturities of outstanding loans, sales of loans, maturities of investment
securities and other short-term investments and funds provided from operations.
While scheduled loan payments and maturing investment securities and short-term
investments are relatively predictable sources of funds, deposit flows and loan
prepayments are greatly influenced by general interest rates, economic
conditions and competition. We invest excess funds in overnight deposits and
other short-term interest-earning assets. We can use cash generated through the
retail deposit market, our traditional funding source, to offset the cash
utilized in investing activities. Our available-for-sale securities and
short-term interest-earning assets can also be used to provide liquidity for
lending and other operational requirements. As an additional source of funds, we
had $40.0 million of availability under existing line of credit agreements at
March 31, 1999. See note 8 of the notes to our consolidated financial
statements.
 
    DEPOSITS.  Our deposit products include a broad selection of deposit
instruments, including commercial checking accounts, negotiable order of

differences being the minimum balance required, the time periods the funds must
remain on deposit and the interest rate.
 
    We utilize nontraditional marketing methods to attract new customers and
savings deposits. Our target market includes internet users, on-line shoppers
and special niche customers. We market our products and services by placing
banner advertisements on portals and Web sites that we believe will attract our
target customers. We also derive a marketing benefit from media coverage.
Additionally, we continually seek to form product and marketing alliances with
other financial services providers to broaden our product and service offerings
and appeal to a broader customer base.
 
    We are competitive in the types of accounts and range of interest rates we
offer on our deposit products. Our deposit levels have increased during the
years ended December 31, 1998 and 1997, primarily as a result of competitive
rates we offer and internet advertising. The weighted average interest rate paid
during the years ended December 31, 1998 and 1997 was 5.77% and 5.17%,
respectively. Although market demand generally dictates which deposit maturities
and rates will be accepted by the public, we intend to continue to promote
checking and negotiable order of withdrawal accounts as well as longer term
certificates of deposit to the extent possible and consistent with asset and
liability management goals.
 
    The following table sets forth the dollar amount of deposits and weighted
average interest rates in the various types of deposit programs offered by us at
December 31, 1997 and 1998 and March 31, 1999, respectively:

    CAPITAL RESOURCES.  We are subject to various regulatory capital
requirements administered by the federal banking agencies. Our failure to meet
minimum capital requirements can initiate certain mandatory and possibly
additional discretionary actions by regulators that, if undertaken, could have a
direct material effect on our consolidated financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
we must meet specific capital guidelines that involve quantitative measures of
our assets, liabilities and certain off-balance-sheet items as calculated under
regulatory accounting practices. Our capital amounts and classifications are
also subject to qualitative judgments by the regulators about components, risk
weightings and other factors. In addition, under regulatory guidelines,
Net.B@nk, our banking subsidiary, may not pay a dividend to Net.B@nk, Inc., if
doing so would cause Net.B@nk to be less than adequately capitalized, as defined
below.
 
    Quantitative measures established by regulation to ensure capital adequacy
require Net.B@nk to maintain minimum amounts and ratios, as set forth in the
table below. Net.B@nk's primary regulatory agency, the Office of Thrift
Supervision, requires Net.B@nk to maintain minimum ratios of tangible capital to
tangible assets of 1.5%, core capital to tangible assets of 3.0% and total
risk-based capital to risk-weighted assets of 8.0%. We believe that as of
December 31, 1998 Net.B@nk met all the capital adequacy requirements to which it
was subject.
 
    As of December 31, 1998, the most recent notification from the Office of
Thrift Supervision categorized Net.B@nk as well capitalized under the regulatory
framework for prompt corrective action. To be well capitalized Net.B@nk must
maintain minimum total risk-based, Tier I risk-based and Tier I leverage ratios
as set forth in the table. No conditions or events have occurred since that
notification that we believe would change Net.B@nk's category.
 
    On February 10, 1999, we received net proceeds of approximately $105.0
million from the sale of 7,290,000 shares of our common stock in a public
offering.

    At March 31, 1999, Net.B@nk had total, core, tangible and Tier I capital
ratios of 35.81%, 24.64%, 24.64% and 35.24%, respectively.
 
    Under current Office of Thrift Supervision regulations, Net.B@nk may pay
dividends and make other capital distributions after giving notice to the Office
of Thrift Supervision.
 
    During the year ended December 31, 1998, Net.B@nk, Inc. and its sole
subsidiary, Net.B@nk, entered into line of credit agreements with The Bankers
Bank. Net.B@nk, Inc. is a party to one such agreement and its sole subsidiary,
Net.B@nk, is a party to two such agreements. Under the terms of our agreement
that expired on October 20, 1998, Net.B@nk, Inc. could borrow 50.0% of the
tangible equity of Net.B@nk, up to $17.0 million, using the stock of Net.B@nk as
collateral. Any amounts borrowed under this line had interest at a fixed rate of
8.0% per annum. During the year ended December 31, 1998, Net.B@nk borrowed and
repaid $12.0 million under the line. Under the terms of the other two
agreements, Net.B@nk may borrow $5.0 million under an unsecured general purpose
line and 99.0% of the value of its investment securities under another line.
Both of the lines bear interest at 25 basis points above the Federal Funds rate,
or 5.0%, at December 31, 1998. Under these agreements at December 31, 1998,
Net.B@nk had an outstanding borrowing of $20.0 million with no stated maturity
secured by investment securities.
 
    During the three months ended March 31, 1999, Net.B@nk repaid $20.0 million
of borrowings outstanding under its line of credit agreement with The Bankers
Bank and $20.0 million under one of its line of credit agreements with the
Federal Home Loan Bank.
 
    As of March 31, 1999, Net.B@nk had borrowed $20.0 million from the Federal
Home Loan Bank at a fixed rate of 4.43%. The borrowing is callable at the second
anniversary date. If not called at the second anniversary date, the borrowing
extends for an additional three years at 4.43%. Also, Net.B@nk has borrowed
$25.0 million from the Federal Home Loan Bank at a fixed rate of 4.64%. The
borrowing is callable at the second anniversary date. If not called at the
second anniversary date, the borrowing extends for an additional eight years at
4.64%. These borrowings are secured by Net.B@nk's investment securities.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
    As of January 1, 1998, we adopted Statement of Financial Accounting
Standards 130, REPORTING COMPREHENSIVE INCOME, and restated prior periods to
conform to the presentation required by
 
                                       38
<PAGE>
SFAS 130. SFAS 130 establishes new rules for the reporting and display of
comprehensive income and its components. SFAS 130 requires unrealized gains or
losses, net of tax, on our available-for-sale securities, which prior to
adoption were reported separately in shareholders' equity, to be included in
other comprehensive income. The adoption of SFAS 130 had no impact on our net
income or shareholders' equity.
 
    As of April 1, 1998, our adopted Statement of Position 98-1, ACCOUNTING FOR
THE COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED FOR INTERNAL USE. SOP 98-1
allows for the capitalization of costs related to the development and
implementation of software obtained for internal use including materials,
payroll and interest costs once the criteria of the SOP have been met. As of
December 31, 1998, $592,402 of these related costs had been capitalized.
 
    As of December 31, 1998, we adopted Statement of Financial Accounting
Standards 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED
INFORMATION. SFAS 131 establishes annual and interim reporting standards for an
enterprise's business segments and related disclosures about its products,
services, geographic areas and major customers. The adoption of SFAS 131 had no
effect on our financial statements for the year ended December 31, 1998 because
we only had one reportable segment.
 
    In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND
HEDGING ACTIVITIES. SFAS 133 establishes standards for derivative instruments
and hedging activities and requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. SFAS 133 is effective for all fiscal quarters
of fiscal years beginning after June 15, 1999. The adoption of SFAS 133 is not
expected to have a significant effect on our financial statements.
 
YEAR 2000
 
    We are working to resolve the potential impact of the year 2000 on the
ability of the computerized information systems we use to accurately process
information that may be date sensitive. Any of the programs we or our service
providers use that recognize a date using "00" as the year 1900 rather than the
year 2000 could result in errors or system failures that could ultimately cause
us or our service providers to become unable to process customer transactions.
This would require us to cease operations pending resolution of the problem.
Such an eventuality would materially adversely affect our business, financial
condition and results of operations. Accordingly, we are devoting significant
attention to identifying year 2000 issues and testing our in-house and external
systems for year 2000 compliance. To date, we have incurred year 2000
remediation costs of approximately $21,000 and have budgeted approximately
$35,000 for total remediation costs. We have been utilizing working capital to
fund our year 2000 compliance program and anticipate that we will continue to do
so.
 
    We began testing our in-house information technology systems during the
second quarter of 1998 and completed this testing during the third quarter of
1998. We have not identified, and do not anticipate, any significant risks or
issues relating to non-information technology systems.
 
    We are also assessing the year 2000 compliance of our outside vendors and
service providers. Because we primarily contract with outside vendors for our
computer application programs, we believe our principal risk relating to year
2000 issues lies in the potential inability of those vendors to process date
sensitive information involving the year 2000. We began testing the systems
provided by these vendors for year 2000 compliance in the third quarter of 1998
and have an Office of Thrift Supervision-mandated completion date of June 30,
1999. In addition, we are contacting each of our vendors to obtain a commitment
that they are or will timely be year 2000 compliant. If such assurances are not
forthcoming, or if we believe for any reason that any of our vendors will not be
year 2000 compliant when required, we plan to contract with other vendors that
would be able to provide similar services at
 
                                       39
<PAGE>
similar costs. Although we cannot offer any assurances, we believe that such
vendors are and will be available. Alternatively, we could bring the outsourced
services in-house by licensing the applicable software and converting it to run
on our platforms or form a correspondent relationship with an unaffiliated year
2000 compliant bank that could service our customers and accounts until we could
provide such services on a year 2000 compliant basis. We believe we could
implement any of the foregoing contingency plans without a material interruption
in our business and without a material adverse effect on our financial
condition, results of operations or cash flows.

    Basic and diluted net income (loss) per common and common equivalent share
have been calculated based on the weighted average number of shares outstanding
during the quarter in accordance with SFAS 128. Potential common shares have not
been included in the calculation related to those quarters with a net loss
because they were antidilutive. All previously reported per share amounts have
been restated to conform to SFAS 128. The total for the quarters differs from
the net loss per share as shown on the statement of operations because of the
issuance of common shares during the year of 1997. On April 13, 1999, we
declared a 3 for 1 split of our common stock effected in the form of a stock
dividend payable on May 14, 1999 to shareholders of record as of the close of
business on April 23, 1999. All references to share and per share amounts have
been retroactively adjusted to reflect the split.

OVERVIEW
 
    Net.B@nk, our sole subsidiary, is the largest federally-insured bank
operating exclusively on the internet. Our mission is to profitably provide a
broad range of banking and financial services to the growing number of internet
users. Our low cost branchless business model allowed us to attain profitability
within a year of acquiring our bank charter and to continue to maintain
profitability while passing along our operating cost savings to customers in the
form of attractive interest rates and low fees. We strive to maintain high asset
quality by employing conservative credit policies. We plan to attract new
accounts through national awareness of the Net.B@nk brand name and to capitalize
on increasing consumer use of the internet.
 
    During 1998, our customer accounts grew from 4,755 to 17,408, deposits grew
from $58.7 million to $283.6 million and total assets grew from $93.2 million to
$388.4 million. During 1998, we added an average of 1,054 net customer accounts
per month. At March 31, 1999, we had 24,634 customer accounts, $332.7 million in
deposits and $526.5 million in total assets. During the four months ended April
30, 1999, we added an average of over 2,900 net customer accounts per month with
4,865 added in April alone. We believe our growth is attributable to our
expanded marketing program, increasing consumer use of the internet and our
ability to offer a broad array of convenient, cost-effective, secure banking
services to this growing customer base.
 
    The following charts demonstrate the growth in our total customer accounts,
checking accounts, deposits and assets:

    Since our equity offering in February 1999, we have continued to experience
rapid growth in our business and have entered into several new programs to
expand and improve our operational and product capabilities. Since February
1999, we have initiated the following:
 
    - EXPANDED MARKETING PROGRAM. We embarked on a new marketing program that
      has been highly successful in reaching our targeted audience and has
      resulted in a significant increase in checking accounts. We believe this
      growth in our checking account base indicates growing customer willingness
      to move their everyday banking activities to Net.B@nk and will result in
      long-term customer relationships. Furthermore, we believe that our
      checking account customers
 
                                       42
<PAGE>
      will visit our Web site more frequently and spend more time on our Web
      site, allowing us to cross-sell a variety of other products and services.
 
    - SERVICING AGREEMENT WITH PNC BANK CORP. We entered into a consumer loan
      processing and servicing agreement with PNC Bank Corp. This agreement will
      allow us to offer consumer loan products on-line. PNC will provide
      origination and loan servicing for these consumer loans as well as
      substantially all consumer loans for which we retain servicing rights on a
      scalable basis and at a favorable cost.
 
    - IMPROVED CUSTOMER SERVICE. We increased our customer support staff by over
      70% in order to maintain high-quality customer service. We have also
      invested in advanced technology and implemented new procedures in order to
      continually improve the quality and responsiveness of our customer
      service.
 
    - STRENGTHENED LENDING AND FINANCIAL OPERATIONS. We expanded our mortgage
      lending capabilities through a mortgage loan origination partnership with
      Virtuallender.com. We strengthened our lending and financial operations by
      adding several individuals to our professional staff. Additionally, we
      have significantly increased our loan portfolio while continuing to
      maintain a conservative lending and investment strategy.
 
INDUSTRY BACKGROUND
 
    THE INTERNET.  The internet enables millions of people worldwide to access
news and information, communicate with each other and conduct business
electronically. According to International Data Corporation, the number of
worldwide internet users is projected to grow from an estimated 159.3 million in
1998 to an estimated 410.4 million by 2002. Additionally, Jupiter Communications
estimates that 37.6 million United States households were on-line in 1998 and
that an estimated 62.6 million households are expected to be on-line in 2002.
On-line households are those that have access to the Web, use a consumer on-line
service or send e-mail.
 
    The internet has become a significant marketplace for buying and selling
goods and services. International Data Corporation forecasts that total
worldwide commerce on the internet will grow from an estimated $50.4 billion in
1998 to an estimated $733.6 billion in 2002. With the emergence of the internet
as a globally accessible, fully interactive medium, many companies that have
traditionally conducted business in person, through the mail or over the
telephone are increasingly conducting business electronically. Many consumers
are showing strong preferences for transacting certain types of business, such
as paying bills, booking airline tickets, trading securities and purchasing
consumer products, electronically rather than in person or over the telephone.
Individuals can now conduct these transactions virtually anywhere at any time.
Many consumers have embraced self-directed on-line transactions because such
transactions can be faster, less expensive and more convenient than transactions
conducted through a teller or an ATM.
 
    In addition to its use as a general commercial medium, the internet has
rapidly emerged as an innovative means of providing financial services. As
finance-related Web sites continue to grow in popularity, many companies are
increasingly offering a variety of financial services, including credit cards,
brokerage services, insurance products and banking services, via the internet.
 
    ELECTRONIC BANKING.  The growth in internet commerce has prompted the
development of electronic banking delivery systems. These forms of electronic
delivery systems provide convenience for customers and allow financial
institutions to lower their overhead costs. The two types of electronic banking
currently available, PC-based home banking and internet banking, are very
different. The characteristics of each are as follows:
 
    - PC-BASED HOME BANKING. PC-based home banking requires PC-based financial
      services software products such as Intuit's QUICKEN, Microsoft's MONEY or
      a bank's proprietary software. Each
 
                                       43
<PAGE>
      product carries its own set of instructions that the customer must learn
      before commencing any banking transactions. The software resides on the
      customer's PC along with his or her account data and requires a dial-up
      modem and manual downloading. Consequently, customers must conduct
      PC-based home banking from the PC containing the customer's software and
      account data. Customers generally must back up their account data at
      frequent intervals to counteract the risk of losing data. Because the
      customer must connect with the financial institution via modem and
      download his or her account data, real-time transactions are not generally
      possible.
 
    - INTERNET BANKING. Unlike PC-based home banking, internet banking requires
      only a secure Web browser for access to the internet and the financial
      institution. Internet banking requires no particular software and does not
      restrict the customer's operations to the location of his or her PC.
      Instead, the customer accesses the financial institution through the
      internet and deposits or transfers funds, pays bills or transacts other
      business on a real-time basis. In contrast, account data remains stored on
      Net.B@nk's secure server at all times, protected by technology designed
      specifically to safeguard such information. No downloading or back-up is
      required, as our server backs up all data and transactions on a continuous
      basis. With internet banking, the information presented to the customer
      remains current at all times.
 
    The use of electronic banking delivery systems, and particularly internet
banking, is growing as consumers find that electronic banking is both convenient
and cost-effective. According to Jupiter Communications, the number of on-line
banking households in the United States is projected to grow from an estimated
6.6 million in 1998 to an estimated 17.1 million in 2002.
 
    INTERNET DEMOGRAPHICS. Demographic surveys indicate that internet users
represent an ideal target market for internet banking. Recent studies by Jupiter
Communications revealed that, in the United States, approximately 47% of on-line
users are college graduates and that approximately 37% are engaged in
professional or managerial occupations. The survey also indicated that the
largest group on-line is adults aged 19 to 34, that approximately 86% of on-line
users are under the age of 50 and that 43% of the on-line audience earns over
$60,000 per year. The attractive demographics of internet users facilitate the
growth of internet banking. Internet users tend to be young and mobile and thus
more inclined to be comfortable with and receptive to the convenience of on-line
commercial transactions. We believe that as internet users enter their prime
earnings and savings years, there will be an increased demand for high-yielding
savings products. Additionally, internet users tend to be professionals with
limited amounts of discretionary time and are attracted to the convenience of
"one-stop shopping" for a full range of financial services.
 
THE NET.B@NK SOLUTION
 
    As the first federally-insured bank to operate solely on the internet, we
believe we have a first mover advantage relative to on-line banks with less
extensive market presence and less established operating histories. In addition,
we have a competitive cost advantage over traditional banks. We also believe our
established position in the marketplace provides us with a competitive advantage
in view of the lead time required for new competitors to obtain a charter and
start an internet bank. We intend to continue to capitalize on this advantage by
aggressively seeking new customers in order to further build market share.
 
    Our customer demographics parallel those of the general internet population
and illustrate Net.B@nk's appeal to households with relatively high incomes.
According to John H. Harland Company, as of September 1998, our customers had an
average age of 44 and a median annual household income in excess of $50,000. We
are ideally positioned to participate in the rapid growth of the internet and
on-line banking based on our:
 
    - ATTRACTIVE INTEREST RATES AND LOW FEES. Our operating costs are generally
      lower than those of traditional "bricks and mortar" banks because we do
      not require a traditional branch network to
 
                                       44
<PAGE>
      generate deposits and conduct operations. We pass our savings in operating
      costs on to customers by offering attractive interest rates and low fees
      in order to generate deposits without sacrificing profit margins. We
      believe our unique business model differentiates Net.B@nk from traditional
      banks offering internet banking services because traditional banks
      frequently offset the incremental expense of their internet banking
      services by charging additional fees or imposing minimum account balances.
 
    - CONVENIENCE AND EASE OF ACCESS. We believe we provide customers with a
      higher level of convenience than can be achieved in a traditional bank
      branch or through PC-based home banking. The internet allows our customers
      to conduct banking activities on a real-time, 7-day-a-week, 24-hour-a-day
      basis from any PC, wherever located, using a secure Web browser. In
      addition, our Web site is designed to be user-friendly and to expedite
      customer transactions with Net.B@nk.
 
    - BROAD SELECTION OF PRODUCTS AND SERVICES. We offer a broad array of
      products and services that customers would typically expect from a
      traditional bank. These products and services include checking and money
      market accounts, certificates of deposit, electronic bill payment, debit
      cards, credit cards, mortgage loans, business equipment leases and
      securities brokerage services. We plan to offer consumer loans, including
      home equity and automobile loans, beginning in the third quarter of 1999.
      We intend to continue to develop additional products and services such as
      insurance products, electronic bill presentment and electronic document
      and image storage in a virtual safe deposit box.
 
    - HIGH-QUALITY SERVICE AND CUSTOMER SATISFACTION. We continually seek ways
      to enhance customer satisfaction. In an effort to serve the needs of our
      customers, we offer services such as electronic bill payment and ATM cards
      without service charges. We also emphasize responsive, courteous customer
      service and utilize a fully-trained dedicated staff who respond to
      inquiries from existing and potential customers and process new accounts.
      Our customers can access account data and information regarding products
      and services 24 hours a day and can currently reach our customer service
      representatives by telephone or e-mail. We strive for the highest level of
      customer satisfaction and believe the significant growth in our customer
      base illustrates our ability to meet our customers' needs.
 
    - ADVANCED SECURITY. A significant barrier to on-line financial transactions
      has been the secure transmission of confidential information over public
      networks. We use sophisticated technology to provide what we believe to be
      among the most advanced security measures currently available in the
      internet banking industry. All banking transactions are encrypted and all
      transactions are routed from the internet server through a "firewall" that
      limits access to the Net.B@nk server. Our systems automatically detect
      attempts by third parties to access other users' accounts and feature a
      high degree of physical security, secure modem access, service continuity
      and transaction monitoring. See "--Security."
 
GROWTH STRATEGY
 
    Our objective is to become the leading provider of a full range of on-line
financial services. We intend to accomplish this objective by implementing the
following strategies:
 
    - BUILD NATIONAL BRAND AWARENESS THROUGH INCREASED MARKETING EFFORTS. We
      have significantly expanded our marketing program and are working with
      nationally known advertising and public relations agencies to build
      national awareness of the Net.B@nk name through a variety of marketing
      initiatives. These initiatives include expanding our advertising media to
      include print and direct mail campaigns; continued advertisement on
      targeted portals such as Yahoo!, Alta Vista, Infoseek, Lycos, AOL and
      Excite and Web sites such as Bank Rate Monitor, iVillage and Motley Fool;
      and the pursuit of strategic alliances with other internet financial
      service providers.
 
                                       45
<PAGE>
      To fund these initiatives, we have increased our marketing expenditures
      from approximately $695,000 for 1998 to a budgeted $6.6 million for 1999.
      During the first quarter of 1999, we applied approximately $400,000 to our
      marketing program and added 7,226 new accounts. We plan to increase our
      print and on-line advertising and continue to explore opportunities in
      broadcast advertising during the course of the year. Our experience
      indicates that by expanding our marketing efforts further, we can heighten
      brand awareness of Net.B@nk on a national scale and significantly increase
      our customer base. See "--Marketing."
 
    - LEVERAGE LOW COST STRUCTURE. Our operating costs are generally lower than
      those of traditional "bricks and mortar" banks because we do not require a
      traditional branch network to generate deposits and conduct operations.
      This is demonstrated by our low ratio of annualized fourth quarter 1998
      noninterest expenses to average earning assets of 1.7% compared to 4.2%
      for commercial banks with $300 million to $500 million in assets, as
      calculated by the FDIC Institution Directory by multiplying the
      noninterest expenses for the quarter divided by the average earning assets
      for the quarter by four. Additionally, our ratio of total assets per
      full-time equivalent employee was $13.9 million as of December 31, 1998
      compared to $2.6 million for commercial banks with $300 million to $500
      million in assets, based on data provided by the FDIC Institution
      directory. We pass our operating cost savings on to customers by offering
      more attractive interest rates on deposit accounts and lower fees than
      those offered generally by traditional banks. We believe this strategy
      attracts deposits without sacrificing profit margins. We intend to
      continue to leverage the fixed-cost aspect of our branchless business
      model to enhance profitability.
 
    - OFFER A BROAD ARRAY OF PRODUCTS AND SERVICES. Our objective is to attract
      customers seeking to combine the convenience of internet banking with the
      broad array of products and services typically offered by traditional
      banks. Toward this end, our product and service offerings include checking
      and money market accounts, certificates of deposit, electronic bill
      payment, debit cards, credit cards, mortgage loans, business equipment
      leases and securities brokerage services. We plan to offer consumer loans,
      including home equity and automobile loans, beginning in the third quarter
      of 1999. We also intend to continue to develop additional products and
      services such as insurance products, electronic bill presentment and
      electronic document and image storage in a virtual safe deposit box. See
      "--Products and Services."
 
    - MAINTAIN HIGH ASSET QUALITY. Our loan portfolio strategy is to maintain a
      conservative loan mix consisting of home mortgage, home equity, consumer,
      commercial and construction loans with an emphasis on high credit quality.
      At our current stage of development, it is more cost-effective for us to
      purchase most of our loans or act as a participating lender with other
      banks rather than originate our own loans. This strategy decreases our
      expenses and allows us to reduce our loan loss exposure by diversifying
      our portfolio. We also emphasize a conservative securities investment
      strategy by investing in fixed income securities such as United States
      Treasury obligations, collateralized mortgage obligations and
      mortgage-backed securities issued by agencies such as Federal National
      Mortgage Association and Federal Home Loan Mortgage Corporation. See
      "--Lending and Investment Activities."
 
    - OUTSOURCE OPERATIONAL FUNCTIONS. To enhance the flexibility and
      scalability of our operations, we outsource certain principal operational
      functions to leading service providers such as NCR, BISYS and CheckFree.
      NCR provides a secure server for the electronic banking software licensed
      to us by Edify Corporation. CheckFree provides electronic bill payment
      systems for us and BISYS processes our transactions and interfaces with
      NCR's secure server. In each of these relationships, we benefit from the
      service provider's expertise and economies of scale while retaining the
      flexibility to take advantage of changes in available technology without
      affecting customer service. We can also respond easily to growth because
      these third-party service
 
                                       46
<PAGE>
      providers have the capacity to process a high volume of transactions. See
      "--Operations-- Service Providers."
 
    - GENERATE NONINTEREST INCOME THROUGH CROSS-MARKETING INITIATIVES. To
      generate additional noninterest income and enhance customer loyalty, we
      cross-market a variety of non-deposit products. We offer credit cards,
      mortgage loans, business equipment leases, securities brokerage services
      and other noninterest income-generating products. We offer these products
      to existing and potential depositors through various marketing techniques,
      such as our Web site, e-mail, on-line advertising and direct mailings.
      This strategy enables us to generate additional earning assets and fee
      income from a growing customer base.
 
PRODUCTS AND SERVICES
 
    DEPOSIT PRODUCTS AND SERVICES.  In order to build our customer base, we
offer a variety of deposit products at attractive interest rates. We are able to
offer attractive interest rates as a result of our low operating costs. We also
attract customers by offering convenient services such as free electronic bill
payment, overdraft protection and ATM cards. Our deposit products and services
include:
 
    - DEPOSIT PRODUCTS. We offer two types of interest-bearing checking
      accounts, a money market account and 6-, 12- and 30-month certificates of
      deposit. We have consistently offered interest rates on our deposit
      accounts that are higher than the national average.
 
    - BILL PAYMENT SERVICE. Through services provided by CheckFree, customers
      can pay their bills on-line through electronic funds transfer or a written
      draft prepared and sent to the creditor. We do not charge a fee for this
      service.
 
    - OVERDRAFT PROTECTION. Overdraft protection is available to all interest
      checking customers who qualify. Customers with interest checking accounts
      may apply for overdraft protection on-line for amounts up to $5,000. If a
      customer has both a money market and an interest checking account, we
      automatically establish overdraft protection between those accounts.
 
    - ATM CARDS. Each customer automatically receives a free ATM card when he or
      she opens an account. Customers can access their accounts at ATMs
      affiliated with the Cirrus, Honor and Avail networks. We do not charge our
      own fee for ATM usage, but the operator of the ATM generally imposes fees.
 
    LENDING PROGRAMS.  To generate fee income and provide a convenient service
to our customers, we offer on-line loans and credit cards as described below.
 
    - MORTGAGE LOANS. Our Web site enables customers to obtain interest rate
      quotes and apply for mortgage loans on-line. We have an agreement with
      mortgage.com (formerly known as First Mortgage Network), under which we
      act as a loan originator on their behalf. We have similar agreements with
      E-loan, Inc., Virtuallender.com and Fidelity Mortgage Services, Inc. under
      which they forward mortgage applications to us. Applications received
      directly through our Web site are processed and closed by mortgage.com.
      Applications received indirectly from mortgage.com, E-loan,
      Virtuallender.com or Fidelity Mortgage Services are processed by the
      respective lender, which in turn receives funding from us and closes the
      loans. We fund each loan that meets our underwriting criteria and sell the
      loans received directly through our Web site to mortgage.com or, in the
      case of loans received indirectly, to the lender from which it was
      received, in each case with the servicing rights released. The loans are
      presold to the same sources at the time of closing so that we do not bear
      any material risk of loss. We generally carry loans receivable on our
      books for an average of approximately 30 days while we await receipt of
      sale proceeds. During this time, we receive interest income on the
      outstanding balance at the rate stated in the mortgage note. We also
      receive a portion of the loan origination fee for providing these funding
      services. We plan to expand our loan offerings to include home equity
 
                                       47
<PAGE>
      loans, home equity lines of credit and automobile loans. We also originate
      and retain a small number of home mortgage loans for our own portfolio.
      See "--Lending and Investment Activities."
 
    - CREDIT CARDS. We offer our customers Visa and MasterCard credit cards
      issued by The Bankers Bank for no annual fee. The Bankers Bank carries the
      credit card loans on its books and we have an income-sharing arrangement
      with The Bankers Bank. Customers can apply for these credit cards on-line.
      The cards prominently display the Net.B@nk logo with the Visa or
      MasterCard emblem appearing in the lower right corner of the card.
 
    NON-BANKING FINANCIAL SERVICES.  To serve as a sole source for the financial
services needs of internet users and to generate additional noninterest income,
we offer a full range of non-banking financial services designed to attract and
retain customers. These services currently include securities brokerage and
business equipment leasing services and in the future will include several new
services such as insurance products.
 
    - SECURITIES BROKERAGE SERVICES. We have contracted with UVEST Investment
      Services, a discount broker, to provide our customers with access to a
      full line of financial services and investment products. We have a
      fee-sharing agreement with UVEST Investment Services. Customers can
      purchase securities without writing checks to their brokers, as trading
      fees are automatically deducted from their Net.B@nk checking or money
      market accounts. Investment proceeds are automatically deposited into the
      customer's Net.B@nk deposit account. Customers enjoy 24-hour on-line
      access, real-time quotes, low commissions and a professional brokerage
      staff.
 
    - BUSINESS EQUIPMENT LEASING. In October 1998, we entered into an agreement
      with Republic Leasing Company that allows our customers, many of whom are
      independent business owners or managers, to lease small business equipment
      through Republic Leasing. We have a fee-sharing agreement with Republic
      Leasing. Lease amounts range from $5,000 to $500,000 and cover virtually
      all types of business equipment. Republic Leasing provides advice,
      comparison quotes and immediate equipment lease financing and holds and
      services all of its leases.
 
    FUTURE PRODUCTS AND SERVICES.  To generate additional interest and fee
income and enhance customer convenience, Net.B@nk plans to introduce a variety
of new products and services. We plan to offer consumer loans, including home
equity and automobile loans, beginning in the third quarter of 1999. Other
future products and services may include insurance products, electronic bill
presentment and electronic document and image storage in a virtual safe deposit
box.
 
LENDING AND INVESTMENT ACTIVITIES
 
    Our loan portfolio strategy is to maintain a conservative loan mix
consisting of home mortgage, home equity, consumer and construction loans with
an emphasis on high credit quality. At our current stage of development, it is
more cost-effective for us to purchase most of our loans or act as a
participating lender with other banks rather than originating our own loans.
This strategy decreases our expenses and allows us to diversify our portfolio.
As we grow, we will continue to develop our portfolio through purchases,
participations and direct originations.
 
    We build our loan portfolio in the following ways:
 
    - PURCHASES. We acquire most of our loans by purchasing packages of specific
      types of loans, such as mortgage, home equity and consumer loans, with
      each package consisting of loans with similar principal amounts, interest
      rates and asset quality. We also purchase portions of commercial loan
      pools, with the seller retaining a portion of the loans to decrease our
      risk. As of March 31, 1999, purchased loans accounted for approximately
      $259.6 million, or 71.3%, of our loan portfolio.
 
                                       48
<PAGE>
    - PARTICIPATIONS. We act as a participating lender in commercial and large
      construction loans with varying banks in the Southeast, including The
      Bankers Bank. We anticipate expanding our participations in construction
      loans to include loans originated nationwide in order to take advantage of
      lower prices for these loans in less competitive geographic areas. As of
      March 31, 1999, participations accounted for approximately $81.2 million,
      or 22.3%, of our loan portfolio.
 
    - DIRECT ORIGINATION. We originate a small number of loans directly with our
      customers. As of March 31, 1999, these loans accounted for approximately
      $23.3 million, or 6.4%, of our loan portfolio.
 
    In addition, as described in "--Products and Services," "-- Lending
Programs" and "--Mortgage Loans," we have agreements with each of mortgage.com,
E-loan, Virtuallender.com, BancMortgage and Fidelity Mortgage Services that
provide that we act as a loan originator on their behalf. From May 1998, when we
began providing services under the first of these agreements, to March 31, 1999,
we funded $258.2 million of loans for third parties. As of March 31, 1999, we
had $35.0 million in loan sale proceeds receivable relating to these agreements.
In the future, we may retain a portion of such loans for our own portfolio.
 
    Our loan committee establishes underwriting standards and criteria for our
loan portfolio and monitors the portfolio on an ongoing basis. The loan
committee applies the same underwriting standards to all of our loans,
regardless of how they are originated. We have also retained an outside
consulting firm to assist the loan committee in its review of the loan portfolio
and to conduct due diligence on purchased loans.
 
    In addition to loans, we invest deposit funds in various fixed income
securities. Our philosophy of high credit quality also guides our investment
decisions. Our fixed income securities portfolio is comprised primarily of
United States Treasury obligations, collateralized mortgage obligations and
mortgage-backed securities issued by agencies such as Federal National Mortgage
Association and Federal Home Loan Mortgage Corporation.
 
CUSTOMER SATISFACTION
 
    We continually seek ways to enhance customer satisfaction. Offering our
customers a high-level of customer service is a top priority of ours and we
believe that it is critical to our success. In an effort to serve the needs of
our customers, we offer services such as electronic bill payment and ATM cards
without service charges. Our customers can access account data and information
regarding products and services 24 hours a day and can currently reach our
customer service representatives by telephone and e-mail.
 
    We are committed to investing in customer service. We recently created a
managerial position dedicated to customer service and hired an individual with
approximately 20 years of experience in customer service and call center
management. We have also expanded our customer support staff by over 70% in
order to maintain high-quality customer service. We have also invested in
technology and implemented new procedures in order to continually improve the
quality and responsiveness of our customer service. To optimize our customer
service resources, we have designed a user-friendly Web site with a goal of
achieving customer self-support. For example, customers can find answers to
their "frequently asked questions" and intuitively navigate our Web site.

MARKETING
 
    The goal of our marketing strategy is to make Net.B@nk the leading brand in
the internet financial services market. Our marketing strategy is designed to
grow our customer base and includes targeted advertising on the internet and
other media, developing strategic partnerships that will enhance our product and
service offerings, cross-marketing initiatives to existing customers and
fostering public relations. Our marketing campaign launched after our February
1999 offering has been highly successful, and we plan to significantly increase
our marketing expenses from $695,000 in 1998 to a budgeted $6.6 million for
1999.
 
    During the first quarter of 1999, we applied approximately $400,000 to our
marketing program and added 7,226 new accounts. We plan to increase our print
and on-line advertising and continue to explore opportunities in broadcast
advertising during the course of the year. We have recently hired additional
marketing support staff and believe that a significant increase in our marketing
initiatives will enable us to increase our name recognition and grow our
customer and deposit base on a national scale.
 
    ADVERTISING STRATEGIES.  We have allocated the majority of our advertising
budget to on-line advertising because we believe it is a rapidly growing medium
that best reaches our target audience. We currently market our products and
services by placing banner ads on portals such as Yahoo!, Alta Vista, Infoseek,
Lycos, AOL and Excite and Web sites such as Bank Rate Monitor, iVillage and
Motley Fool that our experience indicates will attract our target customers. We
have enhanced our ability to monitor the audience that we reach as well as the
results of our on-line advertising campaign. For example, we track the number of
hits on our Web site that result from a particular advertisement and incorporate
our findings into our subsequent marketing efforts.
 
    We also utilize traditional advertisement media. We have a national print
media campaign aimed at increasing brand awareness. Our print media campaign has
included a series of advertisements in national newspaper and magazines such as
THE WALL STREET JOURNAL, FORBES, PC WORLD and INTERNET LIFE. We added direct
mail marketing to our marketing activities and we are evaluating opportunities
in broadcast advertising.
 
    STRATEGIC PARTNERSHIPS.  We continually seek to form product and marketing
alliances with other internet financial services providers such as
Virtuallender.com and E-loan to broaden our product and service offerings and
attract a broader customer base. We plan to pursue other marketing alliances
such as co-branded credit cards. We believe these alliances provide us with the
opportunity to cross-market our products and services to the customers of these
financial service providers and to our existing customers.
 
    PUBLIC RELATIONS.  We also derive a marketing benefit from media coverage
that we generate through our public relations campaign. We believe this coverage
increases the general public's awareness of Net.B@nk and attracts new customers.
 
COMPETITION
 
    We believe that the principal competitive factors in the banking industry
are market presence, customer service, convenience, product offerings and
deposit and loan rates and associated account fees. While the banking industry
is highly competitive, we believe we compete effectively with our principal
competitors, which are traditional banks, internet banks and other financial
services providers. We believe our low cost structure, which allows us to offer
attractive interest rates and low fees, gives us a competitive advantage over
traditional banks, which must support a physical branch structure. We also
believe our operating history and name recognition give us an advantage over
other independent internet banks, most of which are still in a relatively early
stage of operation. Furthermore, we are able to offer a broader array of
products and services than many non-bank financial services providers. However,
many of our competitors have larger customer bases, greater name recognition and
brand awareness, greater financial and other resources and longer operating
histories. Additionally, new
 
                                       50
<PAGE>
competitors and competitive factors are likely to emerge, particularly in view
of the rapid development of internet commerce. See "Risk Factors--Industry
competition may adversely affect our success."
 
OPERATIONS
 
    ACCOUNT ACTIVITY.  Customers can access Net.B@nk through any internet
service provider by means of an acceptable secure Web browser. In doing so,
customers can apply for loans, review account activity, enter transactions into
an on-line account register, pay bills electronically, conduct brokerage
transactions, receive statements by mail and print bank statement reports from
any PC with a secure Web browser, regardless of its location. To open a new
account, the customer completes the on-line enrollment form on our Web site,
prints the signature card, signs it and mails it to us. Customers can make
deposits into an open account at Net.B@nk via direct deposit programs, by
transferring funds between Net.B@nk accounts, by wire transfer, by mail or in
person at our principal executive offices. No teller line is maintained,
however, and we do not have or intend to establish a physical branch system.
Customers can also make withdrawals and have access to their accounts at ATMs
that are affiliated with the Cirrus, Honor and Avail networks, which provides
added customer convenience.
 
    SERVICE PROVIDERS.  We have negotiated relationships with a select group of
service providers who not only provide us with significant quality, security,
reliability, performance and marketing capabilities, but also play an integral
role in implementing our full financial services strategy. Because we outsource
our principal operational functions to experienced third-party service providers
that have the capacity to process a high volume of transactions, we can respond
easily to growth. Moreover, we have preserved a degree of flexibility that
enables us to assess and evaluate our product offerings and delivery structure
on an ongoing basis and to incorporate other alliance opportunities as they
present themselves. Should any of these relationships terminate, however, we
believe we could secure the required services from an alternative source without
material interruption of our operations. Our principal service providers are
described below:
 
    - NCR. NCR provides operational support for our internet banking and bill
      payment applications. Specifically, NCR provides a secure Web site,
      software that performs services relating to our infrastructure and other
      electronic banking services. NCR also hosts Edify's electronic banking
      software on its secure server and provides the interface necessary to link
      our servers with those used by BISYS and CheckFree.
 
    - BISYS. We receive core systems processing services, such as deposit
      account, loan and year-end processing services, from BISYS. The BISYS
      server interfaces with NCR's secure server and verifies customer passwords
      and identification. BISYS also operates our ATM and debit card systems.
 
    - EDIFY. Edify licenses its Electronic Banking System and Electronic
      Workforce software, a suite of internet banking applications, to us. Edify
      also maintains the software and provides consulting services as needed.
 
    - CHECKFREE. CheckFree provides electronic bill paying services to our
      customers. Customers can pay their bills on-line through electronic funds
      transfer or a written draft prepared and sent to the creditor.
 
    - UVEST INVESTMENT SERVICES. UVEST Investment Services provides discount
      brokerage services to our customers. UVEST Investment Services executes
      the trades and receives a commission that is automatically deducted from
      our customer's deposit account.
 
    - MORTGAGE.COM. mortgage.com processes mortgage loan applications submitted
      through our Web site. It reviews the application, contacts the customer
      and closes the loan for us.
 
    - PNC BANK CORP. We plan to offer consumer loans, including home equity and
      automobile loans, in the third quarter of 1999. PNC will originate and
      service these loans and will service other consumer loans on a servicing
      released basis.
 
                                       51
<PAGE>
    As part of our outsourcing strategy, we will continue to explore the
outsourcing of a variety of our operations, including customer service, new
product offerings and certain lending and portfolio management activities.
 
SECURITY
 
    Our ability to provide our customers with secure financial services over the
internet is of paramount importance. We continually evaluate the internet
systems, services and software used in our operations to ensure that they meet
the highest standards of security. The following are among the security measures
that are in place:
 
    ENCRYPTED TRANSACTIONS.  All banking transactions and internet
communications are encrypted so that sensitive information is not transmitted
over the internet in a form that can be read or easily deciphered. Encryption of
internet communications is accomplished through the use of the Netscape Secure
Sockets Layer technology. This technology is the standard for encryption on the
internet and is currently used by Netscape's NAVIGATOR (Version 2.0 or higher)
and Microsoft's INTERNET EXPLORER (Version 3.0 or higher). Messages between our
server and BISYS are encrypted using DES encryption, which is described in
"--Isolated Bank Server" below.
 
    SECURE LOGON.  To eliminate the possibility that a third party may download
Net.B@nk's or a customer's password file, user identification and passwords are
not stored on the internet or the Web server. Furthermore, passwords are strings
of six to eight alpha-numeric characters, which makes the chance that a password
can be randomly guessed less than one in one trillion.
 
    ISOLATED BANK SERVER.  The computer used to provide our services cannot be
accessed directly through the internet. It is on a private connection, or
intranet, that provides two-way communication between the isolated bank server
and the NCR internet server. Consequently, an internet user cannot directly
access the computer that actually provides our services.
 
    All banking services are routed from the NCR server through a firewall. The
firewall is a combined software and hardware product that precisely defines,
controls and limits the access to "internal" computers from "outside" computers
across a network. Use of this firewall means that only authenticated bank
customers or administrators may send or receive transactions through it, and the
firewall itself is immune to penetration from the network. In other words, the
firewall is a mechanism used to protect our server from the freely accessible
internet.
 
    Furthermore, all messages sent or received between the NCR server and our
server are encrypted using DES encryption. This is a symmetric key algorithm and
is highly secure because it is not susceptible to standard ciphertext attacks.
Thus, even if a perpetrator were able to route a message to our server through
the firewall, the message could not be encrypted in a way that would be
considered valid by the server. As a result, our server would reject the
message.
 
    AUTHENTICATED SESSION INTEGRITY.  An authenticated user is any user who
signs onto our Web site with a valid user ID and password. Although the vast
majority of authenticated users are legitimate bank customers, our server is
programmed to limit exposure to an authenticated user who is attempting to
defraud Net.B@nk. If the authenticated user alters the URL, which is the command
or request that is sent from the browser to the server, in any way in an attempt
to gain access to other users' accounts, our server immediately detects that the
session integrity variables have been violated. Our server will immediately stop
the session and record the attempt in a log so that our staff can investigate.
 
    PHYSICAL SECURITY.  All servers and network computers reside in secure NCR
facilities. Currently, computer operations supporting our internet access are
based in Columbia, Maryland with backup facilities in Dayton, Ohio. Only
employees with proper photographic identification may enter the primary
building. The computer operations are located in a secure area, with admission
only by key card. Access to our server console requires further password
identification.
 
    SECURE MODEM ACCESS. A private line that is not accessible from the public
network connects our server and BISYS. Our server is connected to CheckFree by a
similar private connection. A dial-up
 
                                       52
<PAGE>
maintenance port also permits access to our server. The modem that provides the
only access to this port is specially protected and is only enabled on an
as-needed basis.
 
    SERVICE CONTINUITY.  NCR and BISYS each provide a fully redundant network
with no single point of failure. Our server is also "mirrored" so that hardware
failures or software bugs should cause no more than a few minutes of service
outage. "Mirroring" means that our server is backed up continuously so that all
data is stored in two physical locations. This network and server redundancy
ensures that access to Net.B@nk will be reliable. However, if customers are not
able to access Net.B@nk over the internet, customers retain access to their
funds through several means, including paper checks, ATM cards, customer service
and an automated telephone response system.
 
    MONITORING.  All customer transactions on our server using services provided
by BISYS and CheckFree produce one or more entries into transactional logs. We
and NCR recognize that it is critical to monitor these logs for unusual or
fraudulent activity. As mentioned previously, any attempt by an authenticated
user to modify the command or request that is sent from the browser to the
server is logged. Additionally, all financial transactions are logged. Bank
personnel review these logs regularly, and we or NCR will note any abnormal or
unusual activity and take appropriate action. Ultimately, vigilant monitoring is
the best defense against fraud.
 
    The preceding security measures are designed to ensure that Net.B@nk is set
up in a secure manner. However, over the long term, our security depends upon
the procedures and standards used for administration of the internet site. Both
NCR and BISYS are required to obtain SAS 70 certification from a national
accounting firm. This is a certification by independent auditors that the NCR
and BISYS computer systems are being managed and operated in a manner consistent
with accepted practices. Both BISYS and NCR have received this certification.
 
    We believe the risk of fraud presented by internet banking is not materially
different from the risk of fraud inherent in any banking relationship. We
believe the three principal reasons for a breach in bank security are:
 
    - Misappropriation from the user of the user's account number or password;
 
    - Penetration of our server by an outside "hacker"; and
 
    - Fraud committed by one of our employees or an employee of one of our
      service providers.
 
Both traditional banks and internet banks are vulnerable to these types of
fraud. By establishing the security measures described above, we believe we have
reduced our vulnerability to the first two types of fraud. To counteract fraud
by employees, associates and consultants, we have established internal
procedures and policies designed to ensure that, as in any bank, proper control
and supervision is exercised over employees, associates and consultants. We also
counteract all types of fraud through daily examination of our transactional
logs.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
    We regard the form and substance of our name and other intellectual property
we have developed as proprietary and attempt to protect them by relying on
intellectual property laws. We have submitted a United States trademark
registration for the Net.B@nk name and take active measures to safeguard our
name and other proprietary intellectual property. Policing unauthorized use of
proprietary information is difficult, however, and litigation may be necessary
to enforce our intellectual property rights.
 
    We own the internet domain name "netbank.com." Domain names in the United
States and in foreign countries are regulated, by the laws and regulations
governing the internet are continually evolving. Additionally, the relationship
between regulations governing domain names and laws protecting intellectual
property rights is unclear. As a result, we may not be able to prevent third
parties from acquiring domain names that infringe or otherwise decrease the
value of our trademark and other intellectual property rights.

SUPERVISION AND REGULATION
 
    References to "we," "us," "our" and "Net.B@nk" generally refer to Net.B@nk,
Inc. and its sole subsidiary, Net.B@nk, on a consolidated basis, except where we
indicate that Net.B@nk, Inc. means only the parent entity and Net.B@nk refers
only to the banking subsidiary.
 
    BACKGROUND.  In connection with its approval of the July 31, 1997
acquisition of our bank charter, the Office of Thrift Supervision required us to
make certain commitments with respect to our ongoing operations. These
commitments included:
 
    - Until July 28, 2000, receiving prior approval from the Office of Thrift
      Supervision before making any changes to our senior management team or
      board of directors;
 
    - Operating within the parameters of our business plan as submitted to the
      Office of Thrift Supervision;
 
    - Obtaining from an independent computer security specialist an independent
      review of, and written report regarding, the internet banking security
      measures we employ;
 
    - Complying with the Office of Thrift Supervision policy statement regarding
      on-line banking;
 
    - Ensuring that our directors and certain executive officers and
      shareholders refrain from disposing of their restricted shares of common
      stock without the prior consent of the Office of Thrift Supervision until
      July 28, 2000;
 
    - Obtaining the approval of the Regional Director of the Office of Thrift
      Supervision with respect to any changes in our stock benefit plans
      effected on or before July 28, 2000;
 
    - Complying with Office of Thrift Supervision directives, if any, that
      require the exercise or forfeiture of participants' rights under our stock
      benefit plans in the event our capital falls below minimum Office of
      Thrift Supervision requirements; and
 
    - Submitting to the Office of Thrift Supervision a structured project plan
      describing the steps and timing required to replace the Web hosting
      services that were previously provided by AT&T Corp. and are now provided
      by NCR.
 
    We and our directors, executive officers and shareholders have complied with
these conditions to date.
 
    On January 8, 1999, the Office of Thrift Supervision granted Carolina First
Corporation permission to sell a portion of its shares of common stock in
Net.B@nk's February 1999 public offering. As a condition to its approval, the
Office of Thrift Supervision required that two of the four directors initially
nominated by Carolina First Corporation resign following completion of the
offering and that those directors be replaced with two outside directors within
six months of the resignations. The Office of Thrift Supervision also required
Carolina First Corporation to refrain from disposing of its remaining shares of
common stock without the prior consent of the Office of Thrift Supervision. We
do not believe that these commitments have or will materially affect our
operations.
 
    Carolina First Corporation currently owns more than five percent of our
outstanding common stock. As a result, Carolina First Corporation is subject to
certain Federal Reserve Board regulations regarding its relationship with
Net.B@nk. Until Carolina First Corporation owns less than five percent of our
outstanding common stock, we will not engage in any activities that are not
permissible under applicable Federal Reserve Board regulations.
 
    SAVINGS AND LOAN HOLDING COMPANY REGULATION.  Savings and loan holding
companies and federal savings banks are extensively regulated under both federal
and state law. The following is a brief summary of certain statutes, rules and
regulations that affect Net.B@nk, Inc. and its banking subsidiary. This summary
is qualified in its entirety by reference to the particular statutory and
regulatory provisions referred to below. This summary is not intended to be an
exhaustive description of the statutes or regulations applicable to our
business. Supervision, regulation and examination of Net.B@nk by regulatory
agencies is intended primarily for the protection of our depositors rather than
our shareholders. The terms bank, savings institution, savings association,
federal savings bank and
 
                                       54
<PAGE>
thrift are used interchangeably in this section to refer to savings associations
such as Net.B@nk, Inc.'s banking subsidiary that are subject to supervision and
regulation by the Office of Thrift Supervision. The terms savings and loan
holding company and holding company are used interchangeably to refer to holding
companies, such as Net.B@nk, Inc., that are subject to supervision and
regulation by the Office of Thrift Supervision.
 
    Net.B@nk, Inc. is registered as a holding company under both the Savings and
Loan Holding Company Act set forth in Section 10 of the Home Owners Loan Act and
the Financial Institutions Code of Georgia. Net.B@nk, Inc. is currently
regulated under these acts by the Office of Thrift Supervision and by the
Georgia Department of Banking and Finance. As a savings and loan holding
company, Net.B@nk, Inc. is required to file with the Office of Thrift
Supervision an annual report and any additional information that the Office of
Thrift Supervision may require under the Savings and Loan Holding Company Act.
The Office of Thrift Supervision also conducts examinations of Net.B@nk, Inc.
and its banking subsidiary.
 
    Generally, savings and loan holding companies and their subsidiaries may not
engage in activities or render any services for or on behalf of their savings
institution subsidiaries for the purpose or with the effect of evading any law
or regulation applicable to the institution. This restriction is designed to
prevent savings and loan holding companies and their affiliates from evading
requirements of the Savings and Loan Holding Company Act that were enacted to
protect a holding company's savings institution subsidiaries. A unitary thrift
holding company, that is, a holding company that owns only one insured
institution whose subsidiary institution satisfies the qualified thrift lender
test (discussed below), however, is not restricted to any statutorily prescribed
list of permissible activities, and the Savings and Loan Holding Company Act and
the Financial Institutions Code of Georgia impose no limits on direct or
indirect non-savings institution subsidiary operations. Net.B@nk, Inc. is a
unitary thrift holding company and qualifies for this exception. However, as
discussed above, we have committed that Net.B@nk, Inc. will not engage in any
activity that is impermissible for bank holding companies under Federal Reserve
Board regulations.
 
    The Savings and Loan Holding Company Act and the Financial Institutions Code
of Georgia make it unlawful for any savings and loan holding company to acquire
control of another savings association or savings and loan holding company
without prior approval from the Office of Thrift Supervision and the Georgia
Department of Banking and Finance. These statutes also prohibit a savings
institution or holding company from merging with, consolidating with or
purchasing all or substantially all of the assets of another institution or
holding company without prior approval. The Office of Thrift Supervision and the
Georgia Department of Banking and Finance take into consideration the financial
and managerial resources and future prospects of the institutions involved when
considering an application for these transactions. This includes consideration
of the competence, experience and integrity of the officers, directors and
principal shareholders of the companies. In addition, the agencies consider the
effect of the transaction on the institution, the insurance risk to the Savings
Association Insurance Fund and the convenience and needs of the community to be
served.
 
    The Office of Thrift Supervision may not approve an acquisition that would
result in the formation of certain types of interstate banking networks. The
Office of Thrift Supervision is precluded from approving an acquisition that
would result in the formation of a holding company that controls savings
institutions in more than one state. If, however, the acquiring company or one
of its savings institution subsidiaries is authorized to acquire control of an
institution or to operate an office in the additional state under a supervisory
acquisition authorized under Section 13(k) of the Federal Deposit Insurance Act
or the statutes of the state in which the institution to be acquired is located
permits the acquisition, then the acquisition may be approved.
 
                                       55
<PAGE>
    Savings and loan holding companies are generally allowed to acquire or to
retain as much as 5% of the voting shares of a savings institution or savings
and loan holding company without regulatory approval.
 
SAVINGS BANK REGULATION
 
    GENERAL.  Net.B@nk is chartered by the Office of Thrift Supervision, a
bureau of the United States Treasury, and is subject to examination by the
Office of Thrift Supervision and the FDIC. The Office of Thrift Supervision
regulates all areas of our banking operations including reserves, lending,
mergers, payment of dividends, interest rates, establishment of branches and
other aspects of our operations. Federal savings banks with assets greater than
or equal to $250 million, like Net.B@nk, must be examined no less frequently
than every 12 months. Federal savings banks with assets less than $250 million
may be examined no less frequently than 18 months, if they are well capitalized
and meet other regulatory requirements. Additionally, the Office of Thrift
Supervision may assess the federal savings bank with the cost of the
examination.
 
    The FDIC insures Net.B@nk's deposits to the maximum extent provided by law.
The major functions of the FDIC with respect to insured federal savings banks
include:
 
    - Paying depositors to the extent provided by law in the event an insured
      federal savings bank is closed without adequately providing for payment of
      depositors' claims; and
 
    - Preventing the continuance or development of unsound and unsafe banking
      practices.
 
    CAPITAL REQUIREMENTS.  Net.B@nk is required to comply with the capital
adequacy standards established by the Office of Thrift Supervision. The Office
of Thrift Supervision has established three basic measures of capital adequacy
for federal savings banks--a risk-based measure, a leverage measure and a
tangible capital measure.
 
    The risk-based capital standards are designed to make regulatory capital
requirements more sensitive to differences in risk profiles among savings
associations, to account for off-balance-sheet exposure, and to minimize
disincentives for holding liquid assets. Assets and off-balance-sheet items are
assigned to broad risk categories, each with appropriate weights. The resulting
capital ratios represent capital as a percentage of total risk-weighted assets
and off-balance-sheet items.
 
    Under risk-based capital standards, the minimum guideline for the ratio of
total capital to risk-weighted assets is 8%. Net.B@nk's risk-based capital ratio
at December 31, 1998 was 15.36%.
 
    Under leverage-based capital standards, the minimum guideline for the ratio
of core capital to tangible assets is 3%. Net.B@nk's leverage ratio at December
31, 1998 was 9.31%. This leverage-based capital guideline, however, is the
minimum requirement. The guidelines provide that federal savings banks which are
not granted the highest regulatory rating shall maintain a core capital to total
adjusted assets ratio of 4%. A higher ratio may be required if warranted by the
risk profile of the federal savings bank.
 
    Under Office of Thrift Supervision regulations, core capital generally
includes:
 
    - Common stockholders' equity;
 
    - Noncumulative perpetual preferred stock and related surplus; and
 
    - Minority interests in the equity accounts of consolidated subsidiaries,
 
    LESS:
 
    - Unidentifiable intangible assets, other than certain amounts of
      supervisory goodwill; and
 
                                       56
<PAGE>
    - Certain investments in certain subsidiaries plus 90% of the fair market
      value of readily marketable purchased mortgage servicing rights and
      purchased credit card relationships, subject to certain conditions.
 
    Total capital, for purposes of the risk-based capital requirement equals the
sum of core capital plus supplementary capital. Supplementary capital includes
the sum of, among other items, perpetual preferred stock not counted as core
capital, limited life preferred stock, subordinated debt and general loan and
lease loss allowances up to 1.25% of risk-weighted assets less certain
deductions. The amount of supplementary capital that may be counted towards
satisfaction of the total capital requirement may not exceed 100% of core
capital, and Office of Thrift Supervision regulations require the maintenance of
a minimum ratio of core capital to total risk-weighted assets of 4%.
 
    Under tangible capital standards, the minimum guideline for the ratio of
tangible capital to tangible assets is 1.5%. Net.B@nk's tangible capital ratio
at December 31, 1998 was 9.31%. Generally, tangible capital is defined as core
capital minus intangible assets and investments in certain subsidiaries and does
not include purchased mortgage servicing rights.
 
    Office of Thrift Supervision regulations have been amended to include an
interest-rate risk component to the risk-based capital requirement. This new
requirement is not expected to have any material effect on our ability to meet
the risk-based capital requirement. The Office of Thrift Supervision also
revised its risk-based capital standards to ensure that its standards provide
adequately for concentration of credit risk, risk from nontraditional activities
and actual performance and expected risk of loss on multi-family mortgages.
 
    Capital requirements higher than the generally applicable minimum
requirement may be established for a particular savings association if the
Office of Thrift Supervision determines that the institution's capital was or
may become inadequate in view of its particular circumstances.
 
    Additionally, the Georgia Department of Banking and Finance requires savings
and loan holding companies, such as Net.B@nk, Inc., to maintain a 5% Tier 1
capital ratio on a consolidated basis. Tier 1 capital is substantially the same
as core capital. As of December 31, 1998, Net.B@nk's Tier 1 capital ratio was
14.44%.
 
    PROMPT CORRECTIVE ACTION.  The Federal Deposit Insurance Corporation
Improvement Act of 1991 established a system of prompt corrective action to
resolve the problems of undercapitalized institutions. Under this system, the
federal banking regulators, which include the Office of Thrift Supervision, the
FDIC, the Office of the Comptroller of the Currency and the Federal Reserve
Board, established five capital categories (well capitalized, adequately
capitalized, undercapitalized, significantly undercapitalized and critically
undercapitalized), and are required to take certain mandatory supervisory
actions, and are authorized to take other discretionary actions, relating to
institutions in the three undercapitalized categories. The severity of the
action depends upon the capital category in which the institution is placed.
Generally, subject to a narrow exception, the federal banking regulator must
appoint a receiver or conservator for an institution that is critically
undercapitalized. The federal banking agencies have specified by regulation the
relevant capital levels for each category.
 
    An institution that is categorized as undercapitalized, significantly
undercapitalized or critically undercapitalized is required to submit an
acceptable capital restoration plan to its appropriate federal banking agency. A
savings and loan holding company must guarantee that a subsidiary depository
institution meets its capital restoration plan, subject to certain limitations.
The controlling holding company's obligation to fund a capital restoration plan
is limited to the lesser of 5% of an undercapitalized subsidiary's assets or the
amount required to meet regulatory capital requirements. An undercapitalized
institution is also generally prohibited from increasing its average total
assets, making acquisitions, establishing any branches or engaging in any new
line of business, except under an accepted capital restoration plan or with FDIC
approval. In addition, the appropriate federal banking
 
                                       57
<PAGE>
agency may treat an undercapitalized institution in the same manner as it treats
a significantly undercapitalized institution, if it determines that those
actions are necessary. The appropriate federal banking agency may also treat an
institution in the well capitalized, adequately capitalized or undercapitalized
categories as if it was in the next lower category based on safety and soundness
considerations relating to factors other than capital levels.
 
    At December 31, 1998, our capital level placed us in the well capitalized
category.
 
    CAPITAL DISTRIBUTIONS.  Office of Thrift Supervision regulations govern the
payment of dividends and other capital distributions of savings associations
such as Net.B@nk. Under new regulations effective April 1, 1999, savings
associations that meet specified criteria must file a notice or an application
with the Office of Thrift Supervision before making a "capital distribution,"
which is defined to include dividends as well as stock repurchases and cash-out
mergers. Savings associations that do not meet these criteria are permitted to
make distributions without prior notice or application. The Office of Thrift
Supervision may deny distribution notices or applications under specified
circumstances.
 
    A savings association must file an application with the Office of Thrift
Supervision and receive the Office of Thrift Supervision's approval of the
application before making the distribution if:
 
    - The association is not eligible for expedited treatment under the agency's
      application processing guidelines;
 
    - The total amount of all of the association's capital distributions,
      including the proposed capital distribution, for the applicable calendar
      year exceeds the association's net income for that year to date plus the
      association's retained net income for the preceding two years;
 
    - The association would not be at least adequately capitalized under the
      Office of Thrift Supervision's prompt corrective action regulations,
      following the distribution; or
 
    - The proposed capital distribution would violate a prohibition contained in
      any applicable statute, regulation or agreement between the association
      and the Office of Thrift Supervision or the FDIC, or violate a condition
      imposed on the association in an application or notice approved by the
      Office of Thrift Supervision.
 
    A savings association is not eligible for expedited treatment if the
association does not have a composite rating of 1 or 2, does not have a
Community Reinvestment Act rating of satisfactory or better, does not have a
compliance rating of 1 or 2, does not meet its minimum capital requirements or
has been notified by Office of Thrift Supervision personnel that it is a problem
or troubled association.
 
    A savings association must file a notice 30 days before a capital
distribution if the association is not required to file an application but:
 
    - The association would not be well capitalized under the prompt corrective
      action regulations following the distribution;
 
    - The proposed capital distribution would reduce the amount of or retire any
      part of the association's common or preferred stock or retire any part of
      debt instruments such as notes or debentures included in capital under the
      Office of Thrift Supervision's capital regulations (other than regular
      payments required under certain debt instruments); or
 
    - The association is a subsidiary of a savings and loan holding company.
 
                                       58
<PAGE>
    The Office of Thrift Supervision may disapprove a notice or deny an
application, in whole or in part, if the Office of Thrift Supervision determines
that:
 
    - The association will be undercapitalized, significantly undercapitalized
      or critically undercapitalized as set forth in the prompt corrective
      action regulations, following the distribution;
 
    - The proposed distribution raises safety or soundness concerns; or
 
    - The proposed distribution violates a prohibition contained in any statute,
      regulation, agreement between the association and the Office of Thrift
      Supervision or the FDIC or a condition imposed in an application or notice
      approved by the Office of Thrift Supervision, unless the Office of Thrift
      Supervision decides to permit the proposed distribution notwithstanding
      the prohibition or condition.
 
    Net.B@nk does not currently meet the criteria for an application. However,
because Net.B@nk is a subsidiary of a savings and loan holding company, it must
file a notice with the Office of Thrift Supervision at least 30 days before it
makes any capital distribution.
 
    LIQUIDITY.  Under Office of Thrift Supervision regulations, savings
associations must maintain an average daily balance of liquid assets in each
calendar quarter of not less than 4% of: (1) the amount of its liquidity base at
the end of the preceding calendar quarter or (2) the average daily balance of
its liquidity base during the preceding quarter. Liquid assets include cash,
certain time deposits, certain bankers' acceptances, certain corporate debt
securities and highly rated commercial paper, securities of certain mutual funds
and specified United States government, state or federal agency obligations. The
liquidity base is the amount of the savings association's net withdrawable
accounts plus its short-term borrowings.
 
    The Office of Thrift Supervision may, to the extent and under conditions it
may prescribe, permit a savings association to reduce its liquid assets below
the minimum amount to meet withdrawals or pay obligations. In addition, the
Office of Thrift Supervision may suspend part or all of the minimum liquidity
requirements whenever it determines that conditions of national emergency or
unusual economic stress exist. Savings institutions also are required to
maintain short-term liquid assets to satisfy Federal Reserve Board requirements.
 
    QUALIFIED THRIFT LENDER REQUIREMENT. A federal savings bank is deemed to be
a qualified thrift lender if: (1) the savings association qualifies as a
domestic building and loan association, as defined in section 7701(a)(19) of the
Internal Revenue Code of 1986 or (2) the savings association's qualified thrift
investments equal or exceed 65% of its portfolio assets on a monthly average
basis in nine out of every 12 months.
 
    Qualified thrift investments generally consist of (1) various
housing-related loans and investments such as residential construction and
mortgage loans, home improvement loans, mobile home loans, home equity loans and
mortgage-backed securities, (2) certain obligations of the FDIC and (3) shares
of stock issued by any Federal Home Loan Bank, the Federal Home Loan Mortgage
Corporation or the Federal National Mortgage Association.
 
    In addition, the following assets may be categorized as qualified thrift
investments in an amount not to exceed 20% in the aggregate of portfolio assets:
 
    - 50% of the dollar amount of residential mortgage loans originated and sold
      within 90 days of origination;
 
    - Investments in securities of a service corporation that derives at least
      80% of its income from residential housing finance;
 
                                       59
<PAGE>
    - 200% of loans and investments made to acquire, develop or construct
      starter homes or homes in credit needy areas (subject to certain
      conditions);
 
    - Loans for the purchase or construction of churches, schools, nursing homes
      and hospitals; and
 
    - Consumer loans.
 
    The term portfolio assets means the savings institution's total assets minus
goodwill and other intangible assets, the value of property used by the savings
institution to conduct its business and liquid assets held by the savings
institution in an amount up to 20% of its total assets.
 
    A savings association that fails to meet the definition of a qualified
thrift lender must either convert to a national bank charter or limit its future
investments and activities, including branching and payments of dividends, to
those permitted for both savings associations and national banks. Further,
within one year of the loss of qualified thrift lender status, a holding company
of a savings association that does not convert to a bank charter must register
as a bank holding company and will be subject to all statutes applicable to bank
holding companies. In order to exercise the powers granted to federally
chartered savings associations and maintain full access to Federal Home Loan
Bank advances, Net.B@nk must continue to meet the definition of a qualified
thrift lender. In addition, Net.B@nk must continue to meet this definition for
Net.B@nk, Inc. to maintain its status as a unitary savings and loan holding
company.
 
    LOANS TO ONE BORROWER LIMITATIONS.  The Home Owners Loan Act generally
requires savings associations to comply with the loans to one borrower
limitations applicable to national banks. National banks generally may make
loans to a single borrower in amounts up to 15% of their unimpaired capital and
surplus, plus an additional 10% of capital and surplus for loans secured by
readily marketable collateral. The Home Owners Loan Act provides exceptions
under which a savings association may make loans to one borrower in excess of
the generally applicable national bank limits. A savings association may make
loans to one borrower in excess of the limits under the following circumstances:
(1) for any purpose, in any amount not to exceed $500,000 or (2) to develop
domestic residential housing units, in an amount not to exceed the lesser of $30
million or 30% of the savings association's unimpaired capital and unimpaired
surplus, provided other conditions are satisfied.
 
    The Federal Institutions Reform, Recovery, and Enforcement Act of 1989
provided that a savings association could make loans to one borrower to finance
the sale of real property which the savings association acquired in satisfaction
of debts previously contracted in good faith, in amounts up to 50% of the
savings association's unimpaired capital and unimpaired surplus. The Office of
Thrift Supervision, however, has modified this standard by limiting loans to one
borrower to finance the sale of real property acquired in satisfaction of debts
to 15% of unimpaired capital and surplus. That rule provides, however, that
purchase money mortgages received by a savings association to finance those
sales that do not constitute "loans" if no new funds are advanced and the
savings association is not placed in a more detrimental position holding the
note than holding the real estate. Therefore, these purchase money mortgages are
not subject to the loans to one borrower limitations.
 
    COMMERCIAL REAL PROPERTY LOANS.  The Home Owners Loan Act limits the
aggregate amount of commercial real estate loans that a federal savings
association may make to an amount not in excess of 20% of the savings
association's assets. Also, the amount in excess of 10% of total assets must be
devoted to small business real property loans.
 
    COMMUNITY REINVESTMENT.  Under the Community Reinvestment Act and the
implementing Office of Thrift Supervision regulations, federal savings banks
have a continuing and affirmative obligation to help meet the credit needs of
their local communities, including low and moderate-income neighborhoods,
consistent with the safe and sound operation of the institution. The Community
Reinvestment Act requires the boards of directors of financial institutions to
adopt a Community
 
                                       60
<PAGE>
Reinvestment Act statement for each assessment area that, among other things,
describes its efforts to help meet community credit needs and the specific types
of credit that the institution is willing to extend. The Office of Thrift
Supervision has established the following three tests to evaluate a federal
savings bank's compliance with the Community Reinvestment Act:
 
    - A lending test which will compare the institution's market share of loans
      in low- and moderate-income areas to its market share of loans in its
      entire service area and the percentage of a bank's outstanding loans to
      low- and moderate-income areas or individuals;
 
    - A services test which will evaluate the provision of services that promote
      the availability of credit to low- and moderate-income areas; and
 
    - An investment test, which will evaluate an institution's record of
      investments in organizations designed to foster community development,
      small- and minority-owned businesses and affordable housing lending,
      including state and local government housing or revenue bonds.
 
    FAIR LENDING.  Congress and various federal agencies, including bank
regulatory agencies, the Department of Housing and Urban Development, the
Federal Trade Commission and the Department of Justice, which are responsible
for implementing fair lending laws in the United States, have been increasingly
concerned that prospective home buyers and other borrowers are experiencing
discrimination in their efforts to obtain loans. In recent years, the Department
of Justice has filed suit against financial institutions that it determined had
discriminated, seeking fines and restitution for borrowers who allegedly
suffered from discriminatory practices. Most, if not all, of these suits have
been settled, some for substantial sums, without a full adjudication on the
merits.
 
    On March 8, 1994, these federal agencies, in an effort to clarify what
constitutes lending discrimination and to specify the factors the agencies will
consider in determining if lending discrimination exists, announced a joint
policy statement detailing specific discriminatory practices prohibited under
the Equal Credit Opportunity Act and the Fair Housing Act. In the policy
statement, three methods of proving lending discrimination were identified:
 
    - Overt evidence of discrimination, when a lender blatantly discriminates on
      a prohibited basis;
 
    - Evidence of disparate treatment, when a lender treats applicants
      differently based on a prohibited factor even where there is no showing
      that the treatment was motivated by prejudice or a conscious intention to
      discriminate against a person; and
 
    - Evidence of disparate impact, when a lender applies a practice uniformly
      to all applicants, but the practice has a discriminatory effect, even
      where the practices are neutral on their face and are applied equally,
      unless the practice can be justified on the basis of business necessity.
 
    FDIC INSURANCE ASSESSMENTS.  Federal deposit insurance is required for all
federally chartered savings associations. Net.B@nk's deposits are insured to a
maximum of $100,000 for each depositor by the Savings Association Insurance Fund
of the FDIC. Net.B@nk is therefore subject to regulation and supervision by the
FDIC to the extent deemed necessary by the FDIC to ensure the safety and
soundness of the Savings Association Insurance Fund. The FDIC is entitled to
have access to reports of examination of Net.B@nk made by the Office of Thrift
Supervision and all reports of condition filed by Net.B@nk with the Office of
Thrift Supervision. The FDIC also may require Net.B@nk to file additional
reports that determines to be advisable for insurance purposes. Additionally,
the FDIC may determine by regulation or order that a specific activity poses a
threat to the Savings Association Insurance Fund and that no Savings Association
Insurance Fund member may engage in the activity directly.
 
    Insurance premiums are paid in semiannual assessments. Under a risk-based
assessment system, the FDIC is required to calculate on a semi-annual basis a
savings association's semiannual assessment based on (1) the probability that
the insurance fund will incur a loss with respect to the institution,
 
                                       61
<PAGE>
taking into account the institution's asset and liability concentration, (2) the
potential magnitude of any such loss and (3) the revenue and reserve needs of
the insurance fund. The semiannual assessment imposed on the Net.B@nk may
increase depending on the Savings Association Insurance Fund revenue and expense
levels, and the risk classification applied to Net.B@nk.
 
    The FDIC has adopted a risk-based assessment system for insured depository
institutions that takes into account the risks attributable to different
categories and concentrations of assets and liabilities. The system assigns an
institution to one of three capital categories: (1) well capitalized; (2)
adequately capitalized; and (3) undercapitalized. These three categories are
substantially similar to the prompt corrective action categories described
above, with the "undercapitalized" category including institutions that are
undercapitalized, significantly undercapitalized, and critically
undercapitalized for prompt corrective action purposes. The FDIC also assigns an
institution to one of three supervisory subgroups within each capital group. The
supervisory subgroup to which an institution is assigned is based on a
supervisory evaluation that the Office of Thrift Supervision provides to the
FDIC and information that the FDIC determines to be relevant to the
institution's financial condition and the risk posed to the deposit insurance
funds. The FDIC determines an institution's insurance assessment rate based on
the institution's capital category and supervisory category.
 
    Since January 1, 1997, Savings Association Insurance Fund members and Bank
Insurance Fund members have the same risk-based assessment schedule which is
$0.00 to $0.27 per $100 of deposits. Beginning January 1, 1997, financing
corporate bond debt service assessments of $0.013 for Bank Insurance Fund
deposits and $0.064 per $100 of deposits for Savings Association Insurance Fund
deposits were added to the Bank Insurance Fund assessable base and Savings
Association Insurance Fund assessable base, respectively. These rates will be in
effect until December 31, 1999. Thereafter, approximately $0.024 per $100 of
deposits will be added to each regular assessment for all insured depositors.
 
    The Deposit Insurance Funds Act of 1996 provided that the Bank Insurance
Fund and the Savings Association Insurance Fund were to be merged, creating the
"Deposit Insurance Fund," on January 1, 1999, provided that bank and savings
association charters were combined by that date. The Treasury Department has
submitted a report to Congress on the development of a common charter for all
insured depository institutions, but as of January 1, 1999, Congress had not
passed any legislation to combine the charters. See "--Elimination of Federal
Savings Association Charter."
 
    The FDIC may terminate an institution's deposit insurance if it finds that
the institution has engaged in unsafe and unsound practices, is in an unsafe or
unsound condition to continue operation, or has violated any applicable law,
regulation, rule, order or condition imposed by the FDIC.
 
    FEDERAL HOME LOAN BANK SYSTEM.  The Federal Home Loan Bank System consists
of 12 regional Federal Home Loan Banks, each subject to supervision and
regulation by the Federal Housing Finance Board. The Federal Home Loan Banks
provide a central credit facility for member savings associations. Collateral is
required. The maximum amount that the Federal Home Loan Bank of Atlanta will
advance fluctuates from time to time in accordance with changes in policies of
the Federal Housing Finance Board and the Federal Home Loan Banks, and the
maximum amount generally is reduced by borrowings from any other source. In
addition, the amount of advances that a savings association may obtain from the
Federal Home Loan Banks will be restricted in the event the institution fails to
constitute a qualified thrift lender. Net.B@nk is a member of the Federal Home
Loan Bank of Atlanta.
 
    FEDERAL RESERVE SYSTEM.  The Federal Reserve Board has adopted regulations
that require savings associations to maintain non-earning reserves against their
transaction accounts, primarily NOW and regular checking accounts. These
reserves may also be used to satisfy liquidity requirements imposed by the
Office of Thrift Supervision. Because required reserves must be maintained in
the form of cash or a non-interest-bearing account at a Federal Reserve Bank,
the effect of this reserve requirement is to reduce the amount of our
interest-earning assets.
 
                                       62
<PAGE>
    Savings institutions also have the authority to borrow from the Federal
Reserve discount window. Collateral is required. Federal Reserve Board
regulations, however, require savings associations to exhaust all Federal Home
Loan Bank sources before borrowing from a Federal Reserve Bank.
 
    TRANSACTIONS WITH AFFILIATES RESTRICTIONS.  Net.B@nk is subject to the
provisions of Section 23A of the Federal Reserve Act and the Office of Thrift
Supervision's implementing regulation. Section 23A places limits on:
 
    - The amount of loans or extensions of credit to affiliates;
 
    - The amount of investment in affiliates;
 
    - The amount of the purchase of assets from affiliates, except for real and
      personal property exempted by the Federal Reserve Board;
 
    - The amount of loans or extensions of credit to third parties
      collateralized by the securities or obligations of affiliates; and
 
    - The amount of any guarantee, acceptance or letter of credit issued on
      behalf of an affiliate.
 
    The aggregate of all of the above transactions is limited in amount, as to
any one affiliate, to 10% of a bank's capital and surplus and, as to all
affiliates combined, to 20% of a bank's capital and surplus. In addition to the
limitation on the amount of these transactions, each transaction must also meet
specified collateral requirements. Net.B@nk must also comply with certain
provisions designed to avoid transactions with affiliates involving low-quality
assets.
 
    Net.B@nk is also subject to the provisions of Section 23B of the Federal
Reserve Act which, among other things, prohibits an institution from engaging in
the above transactions with affiliates unless the transactions are on terms
substantially the same, or at least as favorable to the institution or its
subsidiaries, as those prevailing at the time for comparable transactions with
nonaffiliated companies.
 
    Net.B@nk is also subject to certain restrictions on extensions of credit to
its executive officers, directors, certain principal shareholders and their
related interests. These extensions of credit (1) must be made on substantially
the same terms, including interest rates and collateral, as those prevailing at
the time for comparable transactions with third parties, and (2) must not
involve more than the normal risk of repayment or present other unfavorable
features.
 
    The Home Owners Loan Act and Office of Thrift Supervision regulations
contain additional restrictions on loans and extension of credit to affiliates,
and the Office of Thrift Supervision is authorized to impose additional
restrictions on transactions with affiliates if it determines restrictions are
necessary to ensure the safety and soundness of any savings association.
 
    FUTURE REQUIREMENTS.  Statutes and regulations are regularly introduced
which contain wide-ranging proposals for altering the structures, regulations
and competitive relationships of financial institutions. We cannot predict
whether or what form any proposed statute or regulation will be adopted or the
extent to which our business may be affected by such statute or regulation.
 
    ELIMINATION OF FEDERAL SAVINGS ASSOCIATION CHARTER.  In recent years,
Congress has considered legislation that would eliminate the federal savings
association charter. If this legislation is enacted, Net.B@nk likely would be
required to convert its federal savings bank charter to either a national bank
charter or to a state depository institution charter and Net.B@nk, Inc. would
become a bank holding company subject to regulation by the Federal Reserve Board
and the Georgia Department of Banking and Finance. Congress has also considered
various legislative proposals that would result in the restructuring of federal
regulatory oversight, including, for example, consolidation of the Office of
 
                                       63
<PAGE>
Thrift Supervision into another agency, or creation of a new Federal banking
agency to replace the various agencies which presently exist.

                  RELATIONSHIP WITH CAROLINA FIRST CORPORATION
 
    Carolina First Corporation owns more than five percent of our outstanding
common stock. As a result, Carolina First Corporation is subject to Federal
Reserve Board regulations regarding its relationship with Net.B@nk. Therefore,
we have agreed with Carolina First Corporation that until they own less than
five percent of our outstanding common stock, we will not engage in any
activities that are not permissible banking or non-banking activities under
applicable Federal Reserve Board regulations. These regulations limit the
activities of bank holding companies and their affiliates to those that are
determined to be closely related to banking or to the management or control of
banks. We do not believe that these limitations will impose any material
constraints on our activities.

                            DESCRIPTION OF THE NOTES
 
    The notes will be issued under an Indenture dated as of      , 1999 (the
"Indenture") between Net.B@nk, Inc. and SunTrust Bank, Atlanta, as trustee (the
"Trustee"). A copy of the form of Indenture is filed as an exhibit to the
registration statement of which this prospectus is a part. The terms of the
Indenture are also governed by certain provisions contained in the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following
summaries of certain provisions of the notes and the Indenture do not purport to
be complete and are subject to, and are qualified in their entirety by reference
to, all the provisions of the notes and the Indenture, including the definitions
therein of certain terms that are not otherwise defined in this prospectus and
those terms made a part of the Indenture by reference to the Trust Indenture Act
as in effect on the date of the Indenture. Wherever particular provisions or
defined terms of the Indenture (or of the form of notes that is a part thereof)
are referred to, such provisions or defined terms are incorporated herein by
reference in their entirety. As used in this "Description of the Notes,"
"Net.B@nk" refers to Net.B@nk, Inc. and does not include Net.B@nk, our bank
subsidiary, unless the context otherwise indicates. In cases in which both
Net.B@nk, Inc. and our bank subsidiary, Net.B@nk, are discussed we refer to the
bank subsidiary as the "Bank."
 
GENERAL
 
   
    The notes will be general unsecured subordinated obligations of Net.B@nk and
will be convertible into our common stock as described below under "Conversion
of Notes." The notes will be limited to $100,000,000 aggregate principal amount
($115,000,000 if the underwriters exercise the over-allotment option in full)
and will mature on June 1, 2004, unless earlier redeemed at the option of
Net.B@nk or repurchased at the option of a holder upon a Change of Control.
    
 
   
    The notes will bear interest from the date of original issue at the annual
rate set forth on the cover page of this prospectus, payable semi-annually on
June 1 and December 1, beginning on December 1, 1999, to holders of record at
the close of business on the preceding May 15 and November 15, respectively.
Interest will be computed on the basis of a 360-day year composed of twelve
30-day months.
    
 
    Unless other arrangements are made, interest will be paid by check mailed to
holders entitled thereto. Principal will be payable, and the notes may be
presented for conversion, registration of transfer and exchange, without service
charge, at the office or agency of Net.B@nk or the Trustee maintained for that
purpose in New York, New York or at the offices of the Trustee in Atlanta,
Georgia. Payments, transfers, exchanges and conversions relating to beneficial
interests in notes issued in book-entry form will be subject to the procedures
described under "Form, Denomination, Transfer, Exchange and Book-entry
Procedures" and "Exchange of Book-entry Notes for Certificated Notes."
 
    The Indenture will not contain any financial covenants or any restrictions
on the incurrence of debt by Net.B@nk or any of its subsidiaries.
 
CONVERSION OF NOTES
 
    The holders of notes will be entitled, at any time through the close of
business on the business day immediately preceding the maturity date, subject to
prior redemption or repurchase, to convert any notes or portions thereof (in
denominations of $1,000 in principal amount or multiples thereof) into our
common stock at the conversion price set forth on the cover page of this
prospectus, subject to adjustment as described below; provided that in the case
of notes called for redemption, conversion rights will expire immediately prior
to the close of business on the last business day before the date fixed for
redemption, unless Net.B@nk defaults in payment of the redemption price. A note
(or portion thereof) in respect of which a holder is exercising its option to
require repurchase upon a
 
                                       69
<PAGE>
Change of Control may be converted only if such holder withdraws its election to
exercise such repurchase option in accordance with the terms of the Indenture.
 
    Except as described below, no adjustment will be made on conversion of any
notes for interest accrued thereon or for dividends paid on any common stock we
issue. Holders of notes at the close of business on a record date will be
entitled to receive the interest payable on such note on the corresponding
interest payment date. However, notes surrendered for conversion after the close
of business on a record date, and before the opening of business on the
corresponding interest payment date must be accompanied by funds equal to the
interest payable on such succeeding interest payment date on the principal
amount so converted (unless such note is subject to redemption on a redemption
date between such record date and the corresponding interest payment date). The
interest payment with respect to a note called for redemption on a date during
the period from the close of business on or after any record date to the close
of business on the business day following the corresponding payment date will be
payable on the corresponding interest payment date to the registered holder at
the close of business on that record date (notwithstanding the conversion of
such note before the corresponding interest payment date) and a holder of notes
who elects to convert need not include funds equal to the interest paid. We are
not required to issue fractional shares of our common stock upon conversion of
notes and, in lieu thereof, we will pay a cash adjustment based upon the closing
price of our common stock on the last business day prior to the date of
conversion.
 
    The conversion price is subject to adjustment (under formulae set forth in
the Indenture) upon the occurrence of certain events, including:
 
        (1) The issuance of our common stock as a dividend or distribution on
    our outstanding common stock;
 
        (2) The issuance to all holders of our common stock of certain rights,
    options or warrants to purchase our common stock at less than the current
    market price;
 
        (3) Certain subdivisions, combinations and reclassifications of our
    common stock;
 
        (4) Distributions to all holders of our common stock of Net.B@nk's
    capital stock (other than our common stock) or evidences of indebtedness of
    Net.B@nk or assets (including securities, but excluding those dividends,
    rights, options, warrants and distributions referred to in clauses (1) and
    (2) above, dividends and distributions in connection with the liquidation,
    dissolution or winding up of Net.B@nk and dividends and distributions paid
    exclusively in cash);
 
        (5) Distributions consisting exclusively of cash (excluding any cash
    portion of distributions referred to in clause (4) above or in connection
    with a consolidation, merger or sale of assets of Net.B@nk as referred to in
    clause (2) of the third paragraph below) to all holders of our common stock
    in an aggregate amount that, together with (A) all other such all-cash
    distributions made within the preceding 12 months in respect of which no
    adjustment has been made and (B) any cash and the fair market value of other
    consideration payable in respect of any tender offers by Net.B@nk or any of
    our subsidiaries for our common stock concluded within the preceding 12
    months in respect of which no adjustment has been made, exceeds 20% of our
    market capitalization (being the product of the then current market price of
    our common stock times the number of shares of our then outstanding common
    stock) on the record date for such distribution; and
 
        (6) The purchase of our common stock pursuant to a tender offer made by
    Net.B@nk or any of our subsidiaries that involves an aggregate consideration
    that, together with (A) any cash and the fair market value of any other
    consideration payable in any other tender offer by Net.B@nk or any of our
    subsidiaries for our common stock expiring within the 12 months preceding
    such tender offer in respect of which no adjustment has been made and (B)
    the aggregate amount of any such all-cash distributions referred to in
    clause (5) above to all holders of our common stock within the
 
                                       70
<PAGE>
    12 months preceding the expiration of such tender offer in respect of which
    no adjustments have been made, exceeds 20% of our market capitalization on
    the expiration of such tender offer.
 
    Except as stated above, the conversion price will not be adjusted for the
issuance our of common stock or any securities convertible into or exchangeable
for our common stock or carrying the right to purchase any of the foregoing. No
adjustment in the conversion price will be required unless such adjustment would
require a change of at least 1% in the conversion price then in effect; provided
that any adjustment that would otherwise be required to be made shall be carried
forward and taken into account in any subsequent adjustment.
 
    No adjustment will be made pursuant to clause (4) of the preceding paragraph
if Net.B@nk makes proper provision for each holder of notes who converts a note
to receive, in addition to our common stock issuable upon such conversion, the
kind and amount assets (including securities) if such holder had been a holder
of our common stock at the time of the distribution of such assets or
securities. Rights, options or warrants distributed by Net.B@nk to all holders
of our common stock that entitle the holders thereof to purchase shares of our
capital stock and that, until the occurrence of an event (a "Triggering Event"),
(1) are deemed to be transferred with the common stock, (2) are not exercisable
and (3) are also issued in respect of future issuances of our common stock,
shall not be deemed to be distributed until the occurrence of the Triggering
Event.
 
    In the case of (1) any reclassification or change of our common stock (other
than changes in par value or from par value to no par value or resulting from a
subdivision or a combination) or (2) a consolidation or merger involving
Net.B@nk or a sale or conveyance to another corporation or business entity of
the property and assets of Net.B@nk as an entirety or substantially as an
entirety (determined on a consolidated basis), in each case as a result of which
holders of our common stock shall be entitled to receive stock, other
securities, other property or assets (including cash) with respect to or in
exchange for such common stock, the holders of the notes then outstanding will
be entitled thereafter to convert such notes into the kind and amount of shares
of stock, other securities or other property or assets that they would have
owned or been entitled to receive upon such reclassification, change,
consolidation, merger, sale or conveyance had such notes been converted into our
common stock immediately prior to such reclassification, change, consolidation,
merger, sale or conveyance, after giving effect to any adjustment event,
assuming that a holder of notes would not have exercised any rights of election
as to the stock, other securities or other property or assets receivable in
connection therewith and received per share the kind and amount received per
share by a plurality of non-electing shareholders.
 
    If a taxable distribution to holders of common stock (or other transaction)
results in any adjustment of the conversion price, the holders of notes may, in
certain circumstances, be deemed to have received a distribution subject to the
U.S. federal income tax as a dividend. In certain other circumstances, the
absence of such an adjustment may result in a taxable dividend to the holders of
our common stock. See "Certain Tax Considerations--U.S. Holders--Adjustments to
Conversion Price."
 
    We may, from time to time and to the extent permitted by law, reduce the
conversion price by any amount for any period of at least 20 days, in which case
we shall give at least 15 days' notice of such decrease, if the Board of
Directors has made a determination that such decrease would be in our best
interests, which determination shall be conclusive. We may, at our option, make
such reductions in the conversion price, in addition to those set forth above,
as we deem advisable to avoid or diminish any income tax to our stockholders
resulting from any dividend or distribution of stock (or rights to acquire
stock) or from any event treated as such for income tax purposes. See "Certain
Tax Considerations."
 
SUBORDINATION
 
    The payment of principal of, premium, if any, and interest on the notes,
including amounts payable on any redemption or repurchase, will, to the extent
set forth in the Indenture, be subordinated in right
 
                                       71
<PAGE>
of payment to the prior payment in full of all Senior Indebtedness. Upon any
distribution to creditors of Net.B@nk in a liquidation or dissolution of
Net.B@nk or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding related to Net.B@nk or its property, in an assignment for the benefit
of creditors or any marshalling of Net.B@nk's assets and liabilities, the
holders of Senior Indebtedness will first be entitled to receive payment in full
of all amounts due or to become due thereon before the holders of the notes will
be entitled to receive any payment in respect of the principal of, premium, if
any, or interest on the notes (except that holders of notes may receive
securities that are subordinated at least to the same extent as the notes to
Senior Indebtedness and any securities issued in exchange for Senior
Indebtedness).
 
    We also may not make any payment upon or in respect of the notes (except in
such subordinated securities) and may not acquire any notes for cash or property
(except in such subordinated securities) if (1) a default in the payment of the
principal of, premium, if any, or interest on Senior Indebtedness occurs and is
continuing beyond any applicable period of grace or (2) any other default occurs
and is continuing with respect to Senior Indebtedness that permits holders of
the Senior Indebtedness as to which such default relates to accelerate its
maturity and the Trustee receives a notice of such default (a "Payment Blockage
Notice") from the representative or representatives of holders of at least a
majority in principal amount of Senior Indebtedness then outstanding. Payments
on the notes may and shall be resumed and NetB@nk may acquire notes (A) in the
case of a payment default, upon the date on which such default is cured or
waived, or (B) in the case of a non-payment default, 179 days after the date on
which the applicable Payment Blockage Notice is received (or sooner, if such
default is cured or waived), unless the maturity of any Senior Indebtedness has
been accelerated. No new period of payment blockage may be commenced within 360
days after the receipt by the Trustee of any prior Payment Blockage Notice. No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be the basis for a subsequent
Payment Blockage Notice.
 
    "Senior Indebtedness" with respect to the notes means the principal of,
premium, if any, and interest on, and any fees, costs, expenses and any other
amounts (including indemnity payments) related to the following, whether
outstanding on the date of the Indenture or thereafter incurred or created:
 
        (1) Indebtedness, matured or unmatured, whether or not contingent, of
    Net.B@nk for money borrowed evidenced by notes or other written obligations;
 
        (2) Any interest rate contract, interest rate swap agreement or other
    similar agreement or arrangement designed to protect Net.B@nk or any of its
    subsidiaries against fluctuations in interest rates;
 
        (3) Indebtedness, matured or umatured, whether or not contingent, of
    Net.B@nk evidenced by notes, debentures, bonds or similar instruments or
    letters of credit (or reimbursement agreements in respect thereof);
 
        (4) Obligations of Net.B@nk as lessee under capitalized leases and under
    leases of property made as part of any sale and leaseback transactions;
 
        (5) Indebtedness of others of any of the kinds described in the
    preceding clauses (1) through (4) assumed or guaranteed by Net.B@nk; and
 
        (6) Renewals, extensions, modifications, amendments and refundings of,
    and indebtedness and obligations of a successor person issued in exchange
    for or in replacement of, indebtedness or obligations of the kinds described
    in the preceding clauses (1) through (5), unless the agreement pursuant to
    which any such indebtedness described in clauses (1) through (5) is created,
    issued, assumed or guaranteed expressly provides that such indebtedness is
    not senior or superior in right of payment to the notes;
 
                                       72
<PAGE>
PROVIDED, HOWEVER, that the following shall not constitute Senior Indebtedness:
 
        (A) Any indebtedness or obligation of Net.B@nk in respect of the notes;
 
        (B) Any indebtedness of Net.B@nk to any of its subsidiaries or other
    affiliates;
 
        (C) Any indebtedness that is subordinated or junior in any respect to
    any other indebtedness of Net.B@nk; and
 
        (D) Any indebtedness incurred for the purchase of goods or materials in
    the ordinary course of business.
 
    If the Trustee (or paying agent if other than the Trustee) or any holder
receives any payment of principal of, premium, if any, or interest with respect
to the notes at a time when such payment is prohibited under the Indenture, such
payment shall be held in trust for the benefit of, and shall be paid over and
delivered to, the holders of Senior Indebtedness or their representative as
their respective interests may appear. After all Senior Indebtedness is paid in
full and until the notes are paid in full, holders of the notes shall be
subrogated (equally and ratably with all other indebtedness ranking equally with
the notes) to the rights of holders of Senior Indebtedness to receive
distributions applicable to Senior Indebtedness to the extent that distributions
otherwise payable to the holders of the notes have been applied to the payment
of Senior Indebtedness.
 
    As of March 31, 1999, Net.B@nk had no indebtedness that would be considered
Senior Indebtedness.
 
    Net.B@nk is a legal entity separate and distinct from the Bank. Net.B@nk's
principal asset is the common stock of the Bank. The principal sources of
Net.B@nk's income are dividends, interest and fees from the Bank. Net.B@nk
relies primarily on dividends from the Bank to meet its obligations for payment
of principal and interest on its outstanding debt obligations and corporate
expenses. Accordingly, the notes are effectively subordinated to all existing
and future liabilities of the Bank. The Bank is subject to claims of creditors
for debt obligations, including deposit liabilities, obligations for borrowings
from the Federal Home Loan Bank and securities sold under reverse repurchase
agreements. At March 31, 1999, the Bank's liabilities, including deposits, were
approximately $383.0 million. Moreover, the Bank is subject to certain
restrictions imposed by federal law on any extensions of credit to, and certain
other transactions with, Net.B@nk and certain other affiliates, and on
investments in stock or other securities thereof. In addition, payment of
dividends to Net.B@nk by the Bank is subject to ongoing review by banking
regulators and is subject to various statutory limitations, including approval
by banking regulatory authorities.
 
    Because of these subordination provisions, in the event of a liquidation or
insolvency of Net.B@nk or the Bank, holders of notes may ratably recover less
than the holders of Senior Indebtedness.
 
    No provision contained in the Indenture or the notes will affect our
obligation, which is absolute and unconditional, to pay, when due, principal of,
premium, if any, and interest on the notes. The subordination provisions of the
Indenture and the notes will not prevent the occurrence of any Default or Event
of Default under the Indenture or limit the rights of the Trustee or any other
holder, subject to the provisions described herein, to pursue any other rights
or remedies with respect to the notes.
 
    The Indenture does not prohibit or limit the incurrence of any indebtedness
by Net.B@nk or any subsidiary.
 
PROVISIONAL REDEMPTION BY NET.B@NK
 
   
    We may redeem the notes, in whole or in part, at any time prior to June   ,
2002, at a redemption price equal to $1,000 per $1,000 principal amount of notes
to be redeemed plus accrued and unpaid interest, if any, to the Redemption Date
(the "Provisional Redemption Date") if the closing price of
    
 
                                       73
<PAGE>
the common stock shall have exceeded 150% of the conversion price then in effect
for at least 20 trading days within a period of 30 consecutive trading days
ending on the trading day prior to the date of mailing of the notice of
provisional redemption (the "Notice Date," which date shall be no more than 60
nor less than 30 days prior to the Provisional Redemption Date).
 
    Upon any Provisional Redemption, Net.B@nk will make an additional payment in
cash (the "Make-Whole Payment") with respect to the notes called for redemption
to holders on the Notice Date in an amount equal to $      per $1,000 principal
amount of notes, less the amount of any interest actually paid on such note
prior to the Notice Date. NET.B@NK WILL BE OBLIGATED TO MAKE THE MAKE-WHOLE
PAYMENT ON ALL NOTES CALLED FOR PROVISIONAL REDEMPTION, INCLUDING ANY NOTES
CONVERTED AFTER THE NOTICE DATE AND PRIOR TO THE PROVISIONAL REDEMPTION DATE.
 
OPTIONAL REDEMPTION BY NET.B@NK
 
   
    At any time on or after June   , 2002, we have the option to redeem the
notes on at least 30 but not more than 60 days' notice, in whole at any time or
in part from time to time, at the following prices (expressed in percentages of
the principal amount), together with accrued interest to the date fixed for
redemption if redeemed on or after:

    If fewer than all the notes are to be redeemed, the Trustee will select the
notes to be redeemed in principal amounts of $1,000 or integral multiples
thereof by lot or, in its discretion, on a pro rata basis. If any note is to be
redeemed in part only, a new note or notes in principal amount equal to the
unredeemed principal portion thereof will be issued. If a portion of a holder's
notes is selected for partial redemption and such holder converts a portion of
such notes, such converted portion shall be deemed to be taken from the portion
selected for redemption. No sinking fund is provided for the notes.
 
REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, each holder of notes shall have
the right to require us to repurchase such holder's notes in whole or in part in
integral multiples of $1,000 at a purchase price in cash in an amount equal to
100% of the principal amount thereof, together with accrued and unpaid interest
to the date of purchase, pursuant to an offer (the "Change of Control Offer")
made in accordance with the procedures described below and the other provisions
in the Indenture.
 
    A "Change of Control" means an event or series of events in which:
 
        (1) Any "person" or "group" (as such terms are used in Sections 13(d)
    and 14(d) of the Exchange Act) acquires "beneficial ownership" (as
    determined in accordance with Rule 13d-3 under the Exchange Act), directly
    or indirectly, of more than 50% of the combined voting power of the then
    outstanding securities entitled to vote generally in elections of directors
    of Net.B@nk (the "Voting Stock"); or
 
        (2) Net.B@nk consolidates with or merges into any other corporation or
    business entity, or conveys, transfers or leases all or substantially all of
    its assets to any person, or any other corporation or business entity merges
    into Net.B@nk, and, in the case of any such transaction, the outstanding
    common stock of Net.B@nk is changed or exchanged as a result, unless the
    shareholders of Net.B@nk immediately before such transaction own, directly
    or indirectly, at least 51% of the combined voting power of the outstanding
    voting securities of the corporation or
 
                                       74
<PAGE>
    business entity resulting from such transaction in substantially the same
    proportion as their ownership of the Voting Stock immediately before such
    transaction;
 
PROVIDED that a Change in Control shall not be deemed to have occurred if
either:
 
        (A) The closing price per share of the common stock for any 5 trading
    days within the period of ten consecutive trading days ending immediately
    after the announcement of such Change of Control shall equal or exceed 105%
    of the conversion price of the notes in effect on each such trading day; or
 
        (B) At least 90% of the consideration in the Change of Control
    transaction consists of shares of common stock traded on a national
    securities exchange or quoted on the Nasdaq National Market, and as a result
    of such transaction, the notes become convertible solely into such common
    stock.
 
    Within 30 days following any Change of Control, unless Net.B@nk has given
the holders notice of its irrevocable intention to redeem all outstanding notes
as described under "Optional Redemption by Net.B@nk," Net.B@nk shall send by
first-class mail, postage prepaid, to the Trustee and to each holder of notes,
at such holder's address appearing in the security register, a notice (the
"Change of Control Notice") stating, among other things, that a Change of
Control has occurred, the purchase price, the purchase date, which shall be a
business day no earlier than 30 days nor later than 60 days from the date such
notice is mailed, and certain other procedures that a holder of notes must
follow to accept a Change of Control Offer or to withdraw such acceptance.
 
    Net.B@nk will comply, to the extent applicable, with the requirements of
Rule 13e-4 under the Exchange Act and other securities laws or regulations in
connection with the repurchase of the notes as described above.
 
    Future indebtedness of Net.B@nk may contain prohibitions of certain events
that would constitute a Change of Control or require Net.B@nk to offer to
repurchase such indebtedness upon a Change of Control. Moreover, the exercise by
the holders of notes of their right to require Net.B@nk to purchase the notes
could cause a default under such indebtedness, even if the Change of Control
itself does not, due to the financial effect of such purchase on Net.B@nk.
Finally, Net.B@nk's ability to pay cash to holders of notes upon a purchase may
be limited by Net.B@nk's then existing financial resources. There can be no
assurance that sufficient funds will be available when necessary to make any
required purchases. Furthermore, the Change of Control provisions may in certain
circumstances make more difficult or discourage a takeover of Net.B@nk and the
removal of the incumbent management.
 
CERTAIN COVENANTS
 
    MAINTENANCE OF STATUS AS INSURED DEPOSITORY INSTITUTION.  Net.B@nk has
agreed that it will do or cause to be done all things necessary to preserve and
keep in full force and effect the status of the Bank as an insured depository
institution and do or cause to be done all things necessary to ensure that
depository accounts of the Bank are insured by the Federal Deposit Insurance
Corporation or any successor organization up to the maximum amount permitted by
12 U.S.C. Section 1811 et seq. and the regulations thereunder or any succeeding
federal law, except as to individual accounts or interests in employee benefit
plans that are not entitled to pass-through insurance under 12 U.S.C. Section
1821 (a)(1)(D).
 
    MERGER, CONSOLIDATION AND SALE OF ASSETS.  Net.B@nk shall not consolidate
with or merge with or into, or convey, transfer or lease all or substantially
all its assets (determined on a consolidated basis), whether in a single
transaction or a series of related transactions, to any person unless:
 
                                       75
<PAGE>
    (1) Either Net.B@nk is the resulting, surviving or transferee person (the
       "Successor Company") or the Successor Company is a corporation organized
       and existing under the laws of the United States or any State thereof or
       the District of Columbia, and the Successor Company (if not Net.B@nk)
       expressly assumes by a supplemental indenture, executed and delivered to
       the Trustee, in form satisfactory to the Trustee, all the obligations of
       Net.B@nk under the Indenture and the notes, including the conversion
       rights described above under "Conversion of Notes;"
 
    (2) Immediately after giving effect to such transaction no Event of Default
       has happened and is continuing; and
 
    (3) Net.B@nk delivers to the Trustee an Officers' Certificate and an opinion
       of counsel, each stating that such consolidation, merger or transfer and
       such supplemental indenture, if any, comply with the Indenture.
 
EVENTS OF DEFAULT AND REMEDIES
 
    An Event of Default is defined in the Indenture as being:
 
    (1) Default in payment of the principal of or premium, if any, on the notes
       when due at maturity, upon redemption or otherwise, including failure by
       Net.B@nk to purchase the notes when required upon a Change of Control
       (whether or not such payment shall be prohibited by the subordination
       provisions of the Indenture);
 
    (2) Default for 30 days in payment of any installment of interest on the
       notes (whether or not such payment shall be prohibited by the
       subordination provisions of the Indenture);
 
    (3) Failure to provide a Change of Control Notice, whether or not such
       Notice or payment pursuant to a Change of Control Offer shall be
       prohibited by the subordination provisions of the Indenture;
 
    (4) Failure to perform any other covenant in the Indenture continuing for 90
       days after written notice by the Trustee or the holders of 25% in
       aggregate principal amount of the notes; and
 
    (5) Certain events involving the bankruptcy, insolvency or reorganization of
       Net.B@nk.
 
The Indenture provides that the Trustee may withhold notice to the holders of
notes of any default (except in payment of principal, premium, if any, or
interest with respect to the notes) if the Trustee considers it in the interest
of the holders of notes to do so.
 
    The Indenture provides that if any Event of Default shall have occurred and
be continuing, the Trustee or the holders of not less than 25% in principal
amount of the notes then outstanding may declare the principal of and premium,
if any, on the notes to be due and payable immediately. At any time after a
declaration of acceleration, but before a judgement or decree based on
acceleration has been obtained, the holders of a majority in aggregate principal
amount of the notes may, under certain circumstances, rescind and annul such
acceleration.
 
    The holders of a majority in principal amount of the notes then outstanding
shall have the right to direct the time, method and place of conducting any
proceedings for any remedy available to the Trustee, subject to certain
limitations specified in the Indenture. The Indenture provides that, subject to
the duty of the Trustee following an Event of Default to act with the required
standard of care, the Trustee will not be under an obligation to exercise any of
its rights or powers under the Indenture at the request or direction of any of
the holders of the notes, unless the Trustee receives satisfactory indemnity
against any associated loss, liability or expense.
 
                                       76
<PAGE>
SATISFACTION AND DISCHARGE; DEFEASANCE
 
    The Indenture will cease to be of further effect as to all outstanding notes
except as to:
 
    (1) Rights of registration of transfer and exchange and Net.B@nk's right of
       optional redemption;
 
    (2) Substitution of apparently mutilated, defaced, destroyed, lost or stolen
       notes;
 
    (3) Rights of holders of notes to receive payments of principal of, premium,
       if any, and interest on, the notes;
 
    (4) Rights of holders of notes to convert to common stock;
 
    (5) Rights, obligations and immunities of the Trustee under the Indenture;
       and
 
    (6) Rights of the holders of notes as beneficiaries of the Indenture with
       respect to the property so deposited with the Trustee payable to all or
       any of them;
 
IF:
 
        (A) Net.B@nk will have paid or caused to be paid the principal of,
    premium, if any, and interest on the notes as and when the same will have
    become due and payable;
 
        (B) All outstanding notes (except lost, stolen or destroyed notes which
    have been replaced or paid) have been delivered to the Trustee for
    cancellation; or
 
        (C) (i) the notes not previously delivered to the Trustee for
    cancellation will have become due and payable or are by their terms to
    become due and payable within one year or are to be called for redemption
    under arrangements satisfactory to the Trustee upon delivery of notice and
    (ii) Net.B@nk will have irrevocably deposited with the Trustee, as trust
    funds, cash, in an amount sufficient to pay principal of and interest on the
    outstanding notes, to maturity or redemption, as the case may be.
 
Such trust may only be established if such deposit will not result in a breach
or violation of, or constitute a default under, any agreement or instrument
pursuant to which Net.B@nk is a party or by which it is bound and Net.B@nk has
delivered to the Trustee an Officers' Certificate and an opinion of counsel,
each stating that all conditions related to such defeasance have been complied
with.
 
    The Indenture will also cease to be in effect (except as described in
clauses (1) through (6) in the immediately preceding paragraph) and the
indebtedness on all outstanding notes will be discharged on the 123rd day after
the irrevocable deposit by Net.B@nk with the Trustee, in trust, specifically
pledged as security for, and dedicated solely to, the benefit of the holders of
notes, of cash, U.S. Government Obligations (as defined in the Indenture) or a
combination thereof, in an amount sufficient, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification thereof delivered to the Trustee, to pay the principal of,
premium, if any, and interest on the notes then outstanding in accordance with
the terms of the Indenture and the notes ("legal defeasance"). Such legal
defeasance may only be effected if:
 
    (1) Such deposit will not result in a breach or violation of, or constitute
       a default under, any agreement or instrument to which Net.B@nk is a party
       or by which it is bound;
 
    (2) Net.B@nk has delivered to the Trustee an opinion of counsel stating that
       (A) Net.B@nk has received from, or there has been published by, the
       Internal Revenue Service a ruling or (B) since the date of the Indenture,
       there has been a change in the applicable federal income tax law, in
       either case to the effect that, based thereon, the holders of the notes
       will not recognize income, gain or loss for federal income tax purposes
       as a result of such deposit, defeasance and discharge by Net.B@nk and
       will be subject to federal income tax on the same amount and in the same
       manner and at the same times as would have been the case if such deposit,
       defeasance and discharge had not occurred;
 
                                       77
<PAGE>
    (3) Net.B@nk has delivered to the Trustee an opinion of counsel to the
       effect that after the 123rd day following the deposit, the trust funds
       will not be subject to the effect of any applicable bankruptcy,
       insolvency, reorganization or similar laws affecting creditors' rights
       generally; and
 
    (4) Net.B@nk has delivered to the Trustee an Officers' Certificate and an
       opinion of counsel stating that all conditions related to the defeasance
       have been complied with.
 
    Net.B@nk may also be released from its obligations under the covenants
described above under "Change of Control" and "Certain Covenants" with respect
to the notes outstanding on the 123rd day after the irrevocable deposit by
Net.B@nk with the Trustee, in trust, specifically pledged as security for, and
dedicated solely to, the benefit of the holders of notes, of cash, U.S.
Government Obligations or a combination thereof, in an amount sufficient in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
the principal of, premium, if any, and interest on the notes then outstanding in
accordance with the terms of the Indenture and the notes ("covenant
defeasance"). Such covenant defeasance may only be effected if:
 
    (1) Such deposit will not result in a breach or violation of, or constitute
       a default under, any agreement or instrument to which Net.B@nk is a party
       or by which it is bound;
 
    (2) Net.B@nk has delivered to the Trustee an Officers' Certificate and an
       opinion of counsel to the effect that the holders of notes will not
       recognize income, gain or loss for federal income tax purposes as a
       result of such deposit and covenant defeasance by Net.B@nk and will be
       subject to federal income tax on the same amount, in the same manner and
       at the same times as would have been the case if such deposit and
       covenant defeasance had not occurred;
 
    (3) Net.B@nk has delivered to the Trustee an opinion of counsel to the
       effect that after the 123rd day following the deposit, the trust funds
       will not be subject to the effect of any applicable bankruptcy,
       insolvency, reorganization or similar laws affecting creditors' rights
       generally; and
 
    (4) Net.B@nk has delivered to the Trustee an Officers' Certificate and an
       opinion of counsel stating that all conditions related to the covenant
       defeasance have been complied with.
 
Following such covenant defeasance, Net.B@nk will no longer be required to
comply with the obligations described above under "Certain Covenants" and will
have no obligation to repurchase the notes pursuant to the provisions described
under "Change of Control."
 
    Notwithstanding any satisfaction and discharge or defeasance of the
Indenture, the obligations of Net.B@nk described under "Conversion of Notes"
will survive to the extent provided in the Indenture until the notes cease to be
outstanding.
 
FORM, DENOMINATION, TRANSFER, EXCHANGE AND BOOK-ENTRY PROCEDURES
 
    Notes will be issued only in fully registered form, without interest
coupons, in minimum denominations of $1,000 and integral multiples in excess
thereof. Notes sold in the offering will be issued only against payment therefor
in immediately available funds.
 
    The notes initially will be represented by one or more notes in registered,
global form without interest coupons (each a "global note" and collectively, the
"global notes"). The global notes will be deposited upon issuance with the
trustee as custodian for the Depository Trust Company ("DTC"), in New York, New
York, and registered in the name of DTC or its nominee, in each case for credit
to an account of a direct or indirect participant in DTC as described below.
 
    Transfer of beneficial interests in the global notes will be subject to the
applicable rules and procedures of DTC and its direct or indirect participants,
which may change from time to time.
 
    Except as set forth below, the global notes may be transferred, in whole and
not in part, only to another nominee of DTC or to a successor of DTC or its
nominee. Beneficial interests in the global
 
                                       78
<PAGE>
notes may not be exchanged for notes in certificated form except in the limited
circumstances described below under "--Exchange of Book-entry Notes for
Certificated Notes."
 
EXCHANGE OF BOOK-ENTRY NOTES FOR CERTIFICATED NOTES
 
    A beneficial interest in a global note may not be exchanged for a note in
certificated form unless (1) DTC (A) notifies Net.B@nk that it is unwilling or
unable to continue as depositary for the global note or (B) has ceased to be a
clearing agency registered under the Exchange Act and in either case Net.B@nk
thereupon fails to appoint a successor depositary with 90 days, (2) Net.B@nk, at
its option, notifies the trustee in writing that it elects to cause the issuance
of Net.B@nk notes in certificated form or (3) there shall have occurred and be
continuing an Event of Default or any event that after notice or lapse of time
or both would be an Event of Default with respect to the notes. In all cases,
certificated notes delivered in exchange for any global note or beneficial
interests therein will be registered in the names, and issued in any approved
denominations, requested by or on behalf of the Depositary, in accordance with
its customary procedures.
 
    CERTAIN BOOK-ENTRY PROCEDURES FOR GLOBAL NOTES.  THE DESCRIPTION OF THE
OPERATIONS AND PROCEDURES OF DTC THAT FOLLOW ARE PROVIDED SOLELY AS A MATTER OF
CONVENIENCE. THESE OPERATIONS AND PROCEDURES ARE SOLELY WITHIN THE CONTROL OF
DTC AND ARE SUBJECT TO CHANGE BY THEM FROM TIME TO TIME. NET.B@NK TAKES NO
RESPONSIBILITY FOR THESE OPERATIONS AND PROCEDURES AND URGES INVESTORS TO
CONTACT DTC OR ITS PARTICIPANTS DIRECTLY TO DISCUSS THESE MATTERS.
 
    DTC has advised Net.B@nk as follows: DTC is a limited purpose trust company
organized under the laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "Clearing Agency" registered pursuant to the provisions of
Section 17A of the Exchange Act. DTC was created to hold securities for its
participants ("participants") and facilitate the clearance and settlement of
securities transactions between participants through electronic book-entry
changes in accounts of its participants, thereby eliminating the need for
physical transfer and delivery of certificates. Participants include securities
brokers and dealers, banks, trust companies and clearing corporations and may
include certain other organizations. Certain of such participants, or their
representatives, together with other entities, own DTC. Indirect access to the
DTC system is available to other entities such as banks, brokers, dealers and
trust companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly ("indirect participants").
 
    DTC has advised Net.B@nk that its current practice, upon the issuance of a
global note, is to credit, on its internal system, the respective principal
amount of the individual beneficial interests represented by such global note to
the accounts with DTC of the participants through which such interests are to be
held. Ownership of beneficial interest in the global note will be shown on, and
the transfer of that ownership will be effected only through, records maintained
by DTC or its nominees, with respect to interests of participants, and the
records of participants and indirect participants, with respect to interests of
persons other than participants.
 
    AS LONG AS DTC, OR ITS NOMINEE, IS THE REGISTERED HOLDER OF A GLOBAL NOTE,
DTC OR SUCH NOMINEE, AS THE CASE MAY BE, WILL BE CONSIDERED THE SOLE OWNER AND
HOLDER OF THE NOTES REPRESENTED BY SUCH GLOBAL NOTE FOR ALL PURPOSES UNDER THE
INDENTURE AND THE NOTES. Except in the limited circumstances described above,
owners of beneficial interest in a global note will not be entitled to have any
portions of such global note registered in their names, will not receive or be
entitled to receive physical delivery of notes in definitive form and will not
be considered the owners or holders of the global notes, or any notes
represented thereby, under the Indenture or the notes. Accordingly, each person
owning a beneficial interest in the global note must rely on the procedures of
DTC and, if such
 
                                       79
<PAGE>
person is not a participant, those of the participant through which such person
owns its interest, in order to exercise any rights of a holder under the
Indenture or such note.
 
    Investors may hold their interests in the global note directly through DTC,
if they are participants in such system, or indirectly through organizations
that are participants in such system. All interests in a global note will be
subject to the procedures and requirements of DTC.
 
    The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interests in a global note to such persons may be limited to
that extent. Because DTC can act only on behalf of its participants, which in
turn act on behalf of indirect participants and certain banks, the ability of a
person having beneficial interests in a global note to pledge such interests to
persons or entities that do not participate in the DTC system, or otherwise take
actions in respect of such interests, may be affected by the lack of a physical
certificate evidencing such interests.
 
    Cash payment of the principal of, interest on, or the redemption or
repurchase of the global note will be made to DTC or its nominee, as the case
may be, as the registered owner of the global note by wire transfer of
immediately available funds on each relevant payment date. Neither Net.B@nk, the
Trustee nor any of their respective agents will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a global note including any delay by DTC or
any participant or indirect participant in identifying the beneficial ownership
interests, and Net.B@nk and the Trustee may conclusively rely on, and shall be
protected in relying on, instructions from DTC for all purposes.
 
    Net.B@nk expects that DTC or its nominee, upon receipt of any cash payment
of principal, interest or the redemption or repurchase price in respect of a
global note representing any notes held by it or its nominee, will immediately
credit participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such global note for
such notes as shown on the records of DTC or its nominee (adjusted as necessary
so that such payments are made with respect of whole notes only), unless DTC has
reason to believe that it will not receive payment on such payment date.
Net.B@nk also expects that payments by participants to owners of beneficial
interests in such global note held through such participants will be governed by
standing instructions and customary practices, as is now the case with
securities held for the accounts of customers registered in "street name." Such
payments will be the responsibility of such participants.
 
    Redemption notices will be sent to DTC or its nominee. If less than all
notes are being redeemed, DTC's practice is to determine by lot the amount of
the holdings of each participant in such issue to be redeemed.
 
    Neither DTC or its nominee will consent or vote with respect to the notes.
Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as
possible after the record date. The omnibus proxy assigns DTC's, or its
nominee's, consenting or voting rights to those participants to whose accounts
the notes are credited on the record date identified in a listing attached to
the omnibus proxy.
 
    Interests in the global notes will trade in DTC's Same-Day Funds Settlement
System, and secondary market trading activity in such interests will therefore
settle in immediately available funds, subject to all cases to the rules and
procedures of DTC and its participants. Transfers between participants in DTC
will be effected in accordance with DTC's procedures, and will be settled in
same-day funds.
 
    DTC has advised Net.B@nk that it will take any action permitted to be taken
by a holder of notes, including the presentation of notes for exchange as
described below and the conversion of notes, only at the direction of one or
more participants to whose account with DTC interests in the global notes are
credited and only in respect of such portion of the aggregate principal amount
of the notes as to which such participant or participants has or have given such
direction. However, if there is an Event
 
                                       80
<PAGE>
of Default, as defined above, under the notes, DTC reserves the right to
exchange the global notes for notes in certificated form, and to distribute such
notes to its participants.
 
    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of beneficial ownership interests in the global note among
participants, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time.
 
    None of Net.B@nk, the Trustee nor any of their respective agents will have
any responsibility for the performance by DTC, its participants or indirect
participants of their respective obligations under the rules and procedures
governing its operations, including maintaining, supervising or reviewing the
records relating to, or payments made on account of, beneficial ownership
interests in global notes.
 
MODIFICATIONS OF THE INDENTURE
 
    The Indenture contains provisions permitting Net.B@nk and the Trustee, with
the consent of the holders of not less than a majority in principal amount of
the notes at the time outstanding, to modify the Indenture or any supplemental
indenture or the rights of the holders of notes, except that without the consent
of the holder of each note so affected no such modification shall:
 
    (1) Extend the fixed maturity of any note;
 
    (2) Reduce the rate or extend the time of payment of interest thereon;
 
    (3) Reduce the principal amount thereof or premium, if any, thereon;
 
    (4) Reduce any amount payable upon redemption thereof;
 
    (5) Change the obligation of Net.B@nk to repurchase any note upon the
       happening of a Change of Control;
 
    (6) Impair or affect the right of a holder to institute suit for the payment
       thereof;
 
    (7) Change the currency in which the notes are payable;
 
    (8) Modify the subordination provisions of the Indenture in a manner adverse
       to the holders of notes; or
 
    (9) Impair the right to convert the notes into common stock subject to the
       terms set forth in the Indenture.
 
    In addition, no modification shall reduce the foregoing percentage of notes
without the consent of the holders of all of the notes then outstanding.
 
GOVERNING LAW
 
    The Indenture and the notes will be governed by and construed in accordance
with the laws of the State of New York.
 
CONCERNING THE TRUSTEE
 
    SunTrust Bank, Atlanta, the Trustee under the Indenture, has been appointed
by Net.B@nk as the paying agent, conversion agent, registrar and custodian with
regard to the notes. The Trustee and/or its affiliates may in the future provide
banking and other services to Net.B@nk in the ordinary course of their
respective businesses.

                          DESCRIPTION OF CAPITAL STOCK
 
    Our authorized capital stock consists of 100,000,000 shares of common stock,
$.01 par value, and 10,000,000 shares of preferred stock, no par value. The
following summary is qualified by reference to our Articles of Incorporation and
Bylaws, which are incorporated by reference as exhibits to the Registration
Statement of which this prospectus is a part.
 
COMMON STOCK
 
    Holders of our common stock are entitled to one vote per share in the
election of directors and on all other matters submitted to a vote of the
holders of common stock and do not have cumulative voting rights. The holders of
common stock are entitled to receive dividends, if any, as may be declared from
time to time by the Board of Directors out of legally available funds, and in
the event of liquidation, dissolution or winding-up of Net.B@nk, to share
ratably in all assets available for distribution.
 
PREFERRED STOCK
 
    The authorized preferred stock may be issued from time to time in one or
more designated series or classes. The Board of Directors, without approval of
the shareholders, is authorized to establish the voting, dividend, redemption,
conversion, liquidation and other relative provisions as may be provided in a
particular series or class. The issuance of preferred stock, while providing
flexibility in connection with possible acquisitions and other corporate
purposes, could, among other things, adversely affect the voting power of the
holders of common stock and, under certain circumstances, make it more difficult
for a third party to acquire, or discourage a third party from acquiring, a
majority of our outstanding voting stock. We have no present intention to issue
any series or class of preferred stock.
 
SPECIAL MEETINGS OF SHAREHOLDERS
 
    Our Bylaws provide that special meetings of the shareholders may be called
at any time for any purpose by the Chief Executive Officer or by the presiding
officer of the Board of Directors. Either our Chief Executive Officer or the
Secretary is required to call a special meeting when (1) requested in writing by
any two or more of the directors or (2) requested in writing by shareholders
owning shares representing at least 25% of all the votes entitled to be cast on
any issue proposed to be considered at such meeting.
 
SUPERMAJORITY APPROVAL OF CERTAIN TRANSACTIONS
 
    Our Articles of Incorporation require the affirmative vote of the holders of
two-thirds of the voting stock to approve certain mergers, share exchanges and
dispositions of our assets unless at least two-thirds of the members of the
Board of Directors approve the proposed transaction. If such approval by the
Board of Directors is obtained, approval by the vote of a majority of the
outstanding shares entitled to vote is required. This provision may tend to
discourage attempts by third parties to acquire Net.B@nk in a hostile takeover
effort. It may also permit a minority of directors and shareholders to prevent a
business combination regardless of the terms of the proposed transaction.
 
CLASSIFIED BOARD AND REMOVAL OF DIRECTORS
 
    Our Articles of Incorporation also provide that the Board of Directors will
be divided into three classes serving staggered three-year terms and that a
director may only be removed by the vote of two-thirds of the outstanding shares
entitled to vote in an election of directors. These provisions could enable a
minority of our shareholders to prevent the removal of a director sought to be
removed by a
 
                                       82
<PAGE>
majority of the shareholders and may tend to enhance management's ability to
retain control over our affairs and to preserve the director's present position
on the Board.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Our Bylaws contain indemnification provisions providing that our directors,
officers and employees or agents will be indemnified against expenses actually
and reasonably incurred by them if they are successful on the merits of a claim
or proceeding.
 
    When a case or dispute is not ultimately determined on its merits (i.e., it
is settled), the indemnification provisions provide that Net.B@nk will indemnify
directors when they meet the applicable standard of conduct. The applicable
standard of conduct is met if the director acted in good faith and in a manner
he or she reasonably believed to be in or not opposed to the best interests of
Net.B@nk, and with respect to an employee benefit plan, for a purpose the
director believed in good faith to be in the interests of the participants and
beneficiaries of the plan. The standard of conduct with respect to any criminal
action or proceeding is met if the director had no reasonable cause to believe
his or her conduct was unlawful. Whether the applicable standard of conduct has
been met is determined by the Board of Directors, the shareholders or
independent legal counsel in each specific case.
 
    We can also provide for greater indemnification than that set forth in our
Bylaws if we choose to do so, subject to approval by our shareholders. We may
not, however, indemnify a director for liability arising out of circumstances
which constitute exceptions to limitation of a director's liability for monetary
damages. See "--Limitation of Liability."
 
    The indemnification provisions of the Bylaws specifically provide that we
may purchase and maintain insurance on behalf of any director against any
liability asserted against such person and incurred by him or her in any such
capacity, whether or not we would have had the power to indemnify against such
liability.
 
    We are not aware of any pending or threatened action, suit or proceeding
involving any of our directors or officers for which indemnification from
Net.B@nk may be sought.
 
LIMITATION OF LIABILITY
 
    Article X of our Articles of Incorporation, subject to certain exceptions,
eliminates the potential personal liability of a director for monetary damages
to Net.B@nk and to the shareholders of Net.B@nk for breach of a duty as a
director. There is no elimination of liability for:
 
    - A breach of duty involving appropriation of a business opportunity of
      Net.B@nk;
 
    - An act or omission not in good faith or involving intentional misconduct
      or a knowing violation of law;
 
    - A transaction from which the director derives an improper material
      tangible personal benefit; or
 
    - As to any payment of a dividend or approval of a stock repurchase that is
      illegal under the Georgia Business Corporation Code, our Articles of
      Incorporation do not eliminate or limit the right of Net.B@nk or its
      shareholders to seek injunctive or other equitable relief not involving
      monetary damages.
 
    We adopted Article X pursuant to the Georgia Business Corporation Code which
allows Georgia corporations, with the approval of their shareholders, to include
in their articles of incorporation a provision eliminating or limiting the
liability of directors, except in the circumstances described above. We included
Article X in our Articles of Incorporation to encourage qualified individuals to
serve and remain as directors of Net.B@nk. Article X was also included to
enhance our ability to secure liability
 
                                       83
<PAGE>
insurance for its directors at a reasonable cost. We maintain liability
insurance covering actions taken by its directors in their capacities as
directors. The Board of Directors believes that Article X will enable us to
secure such insurance on terms more favorable than if such a provision were not
included in the Articles of Incorporation.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the common stock is SunTrust Bank,
N.A., 58 Edgewood Avenue, Atlanta, Georgia 30303.

                           CERTAIN TAX CONSIDERATIONS
 
GENERAL
 
    The following is a discussion of certain U.S. federal income tax and estate
tax consequences of the purchase, ownership and disposition of the notes as of
the date hereof. For purposes of this discussion, a "U.S. Holder" is a holder of
notes that is an individual who is a citizen or resident of the United States, a
corporation or a partnership that is organized under the laws of the United
States or any state thereof or an estate or trust whose income is includible in
gross income regardless of its source. A "Non-U.S. Holder" is a holder of notes
that is not a U.S. Holder. This summary applies only to notes and common stock
held as capital assets within the meaning of Section 1221 of the Internal
Revenue Code of 1986, as amended (the "Code"). It does not discuss all of the
tax consequences that may be relevant to a Holder in light of its particular
circumstances or to Holders subject to special rules, such as dealers in
securities or foreign currencies, financial institutions, life insurance
companies, or regulated investment companies, or to Holders whose functional
currency is not the United States dollar or who hold the notes or the common
stock as part of a synthetic security, conversion transaction, or certain
"straddle" or hedging transactions.
 
    The U.S. federal income tax and estate tax considerations set forth below
are based upon the Code and regulations, rulings and judicial decisions
thereunder as of the date hereof, and such authorities may be repealed, revoked
or modified, possibly with retroactive effect, so as to result in U.S. federal
income tax consequences different from those presented below.
 
U.S. HOLDERS
 
    INTEREST.  Interest on a note should be taxable to a U.S. Holder as ordinary
interest income in accordance with the U.S. Holder's method of accounting for
U.S. federal income tax purposes.
 
    SALE, EXCHANGE OR REDEMPTION OF A NOTE. A U.S. Holder should recognize gain
or loss, if any, on the sale, redemption or other taxable disposition of a note
in an amount equal to the difference, if any, between the U.S. Holder's adjusted
tax basis in the note and the amount received therefor (other than amounts
attributable to accrued and unpaid interest on the notes, which should be
treated as interest for U.S. federal income tax purposes). Subject to the market
discount rules noted under "U.S. Holders--Market Discount and Bond Premium"
below, gain or loss, if any, recognized on the sale, redemption or other taxable
disposition of a note generally should be long-term capital gain or loss if the
note was held for more than one year as of the date of disposition.
 
    MARKET DISCOUNT AND BOND PREMIUM.  If a U.S. Holder acquires a note
subsequent to its original issuance and the note's stated redemption price at
maturity exceeds the U.S. Holder's initial tax basis in the note by more than a
de-minimis amount, the U.S. Holder should generally be treated as having
acquired the note at a "market discount" equal to such excess. In addition, if a
U.S. Holder's initial tax basis in a note exceeds the stated redemption price at
maturity of the note, the U.S. Holder should generally be treated as having
acquired the note with "bond premium" in an amount equal to such excess. U.S.
Holders should consult their tax advisers regarding the existence, if any, and
tax consequences of market discount and bond premium.
 
    CONVERSION OF THE NOTES. A U.S. Holder should not recognize gain or loss
upon conversion of the notes into common stock. The U.S. Holder's tax basis in
shares of common stock received upon conversion should be the same as the U.S.
Holder's adjusted tax basis of the notes converted (reduced by the portion of
such basis allocable to any fractional common stock interest for which the U.S.
Holder receives a cash payment from Net.B@nk). The holding period of the common
stock received in the conversion should include the holding period of the notes
that were converted. A U.S. Holder generally should recognize gain (or loss)
upon a conversion to the extent that any cash paid in lieu of a
 
                                       85
<PAGE>
fractional share of common stock exceeds (or is less than) its tax basis
allocable to such fractional share.
 
    DIVIDENDS.  Dividends paid on common stock received upon conversion will be
taxable to a U.S. Holder as ordinary income, to the extent paid out of
Net.B@nk's current or accumulated earnings and profits. Subject to certain
restrictions, dividends received by a corporate U.S. Holder generally should be
eligible for the 70% dividends received deduction.
 
    SALE OF COMMON STOCK. A U.S. Holder of common stock received on conversion
who sells or otherwise disposes of such stock in a taxable transaction will
recognize capital gain or loss equal to the difference between the cash and the
fair market value of any property received on such sale and the U.S. Holder's
tax basis in such stock. Such gain or loss will be long term gain or loss if the
holding period for such common stock was more than one year.
 
    REDEMPTION OF COMMON STOCK. A redemption by Net.B@nk of some or all of a
U.S. Holder's common stock will be treated as a dividend to the redeeming U.S.
Holder to the extent of Net.B@nk's current and accumulated earnings and profits
unless the redemption meets one of the tests under Section 302(b) of the Code.
If one of the tests under Section 302(b) is met, the redemption will be treated
as an exchange giving rise to capital gain or loss, except to the extent of
declared but unpaid dividends. Such gain or loss will be long term capital gain
or loss if the holding period for such common stock was more than one year. U.S.
Holders should consult their tax advisors as to the application of Section 302
(b) to their particular circumstances.
 
    ADJUSTMENTS TO CONVERSION PRICE.  Pursuant to Treasury Regulations
promulgated under Section 305 of the Code, a U.S. Holder of a note should be
treated as having received a constructive distribution from Net.B@nk upon an
adjustment in the conversion price of the notes if (1) as a result of such
adjustment, the proportionate interest of such U.S. Holder in the assets or
earnings and profits of Net.B@nk is increased and (2) the adjustment is not made
pursuant to a bona fide, reasonable anti-dilution formula. An adjustment in the
conversion price would not be considered made pursuant to such a formula if the
adjustment were made to compensate for certain taxable distributions with
respect to the common stock into which the notes are convertible. Thus, under
certain circumstances, a decrease in the conversion price of the notes may be
taxable to a U.S. Holder of a note as a dividend to the extent of the current or
accumulated earnings and profits of Net.B@nk. In addition, the failure to adjust
fully the conversion price of the notes to reflect distributions of stock
dividends with respect to the common stock may result in a taxable dividend to
the U.S. Holders of the common stock.
 
    BACKUP WITHHOLDING AND INFORMATION REPORTING. A U.S. Holder of a note, or of
common stock issued upon conversion of a note, may be subject to information
reporting and possible backup withholding. If applicable, backup withholding
would apply at a rate of 31% with respect to dividends or interest on, or the
proceeds of a sale, exchange, redemption, retirement, or other disposition of,
such note or common stock, as the case may be, unless (1) such U.S. Holder is a
corporation or comes within certain other exempt categories and, when required,
demonstrates this fact, or (2) provides a taxpayer identification number,
certifies as to no loss of exemption from backup withholding, and otherwise
complies with applicable backup withholding rules.
 
NON-U.S. HOLDERS
 
    THE NOTES.  The payment of interest on a note should generally not be
subject to U.S. federal withholding tax, if (1) the interest is not effectively
connected with the conduct of a trade or business within the United States by
the Non-U.S. Holder, (2) the Non-U.S. Holder does not actually or constructively
own 10% or more of the total combined voting power of all classes of stock of
Net.B@nk entitled to vote, (3) the Non-U.S. Holder is not a controlled foreign
corporation that is related to Net.B@nk actually or constructively through stock
ownership and (4) either (A) the beneficial owner of the note certifies to
Net.B@nk or its agent, under penalties of perjury, that it is not
 
                                       86
<PAGE>
a U.S. Holder and provides its name and address on U.S. Treasury Form W-8 (or on
a suitable substitute form) or (B) a securities clearing organization, bank or
other financial institution that holds customers' securities in the ordinary
course of its trade or business (a "financial institution") and holds the note
certifies under penalties of perjury that such a Form W-8 (or suitable
substitute form) has been received from the beneficial owner by it or by a
financial institution between it and the beneficial owner and furnishes the
payer with a copy thereof.
 
    A Non-U.S. Holder should generally not be subject to U.S. federal income tax
on any gain or income realized in connection with the sale, exchange,
retirement, or other disposition of a note, including the exchange of a note for
common stock, unless the Non-U.S. Holder is an individual who is present in the
United States for 183 days or more in the taxable year of the disposition, and
either (1) has a tax home in the United States and the gain from the disposition
is not attributable to an office of other fixed place of business maintained by
such non-U.S. Holder in a foreign country or (2) the gain from the disposition
is attributable to an office or other fixed place of business maintained by such
non-U.S. Holder in the United States.
 
    A note held directly by an individual who, at the time of death, is not a
citizen or resident of the United States should not be includible in such
individual's gross estate for U.S. estate tax purposes as a result of such
individual's death if the individual does not actually or constructively own 10%
or more of the total combined voting power of all classes of stock of Net.B@nk
entitled to vote and, at the time of the individual's death, if payments with
respect to such note would not have been effectively connected with the conduct
by such individual of a trade or business in the United States. Even if the note
was includible in the gross estate under the foregoing rules, the note may be
excluded under the provisions of an applicable estate tax treaty.
 
    THE COMMON STOCK.  In general, dividends (including any amounts that are
treated as dividends as described above) paid to a Non-U.S. Holder of the common
stock should be subject to U.S. federal income tax withholding at a 30% rate
unless such rate is reduced by an applicable income tax treaty. Dividends that
are effectively connected with such Non-U.S. Holder's conduct of a trade or
business in the United States or, if a tax treaty applies, attributable to a
permanent establishment, or, in the case of an individual, a "fixed base," in
the United States ("U.S. trade or business income") are generally subject to
U.S. federal income tax at regular rates, but are not generally subject to the
30% withholding tax if the Non-U.S. Holder files the appropriate form with the
payer. Any U.S. trade or business income received by a Non-U.S. Holder that is a
corporation may also, under certain circumstances, be subject to an additional
"branch profits tax" at a 30% rate or such lower rate as may be applicable under
an income tax treaty.
 
    Dividends paid to an address in a foreign country are presumed (absent
actual knowledge to the contrary) to be paid to a resident of such country for
purposes of the withholding tax discussed above and, under the current
interpretation of Treasury Regulations, for purposes of determining the
applicability of a tax treaty rate. Effective for payments of dividends made
after December 31, 1999, however, a Non-U.S. Holder of the common stock who
wishes to claim the benefit of an applicable tax treaty rate will be required to
present a U.S. Treasury Form W-8 or documentary evidence confirming the Non-U.S.
Holder's status as a bona fide resident of the particular country under whose
treaty the reduced rate of tax is claimed.
 
    A Non-U.S. Holder of the common stock that is eligible for a reduced rate of
U.S. federal withholding tax pursuant to an income tax treaty may obtain a
refund of any excess amounts withheld by filing an appropriate claim for refund
with the IRS.
 
    A Non-U.S. Holder of the common stock should generally not be subject to
U.S. income or withholding tax on gain realized on the sale, exchange or
redemption (provided that the redemption is treated as the sale or exchange of
the stock) of such stock, unless the Non-U.S. Holder is an individual who is
present in the United States for 183 days or more in the taxable year of the
disposition, and
 
                                       87
<PAGE>
either (1) has a tax home in the United States and the gain from the disposition
is not attributable to an office or other fixed place of business maintained by
such Non-U.S. Holder in a foreign country or (2) the gain from the disposition
is attributable to an office or other fixed place of business maintained by such
Non-U.S. Holder in the United States. Common stock held directly by an
individual who at the time of death is not a citizen or resident of the United
States will nevertheless generally be includible in the gross estate of such
individual for U.S. estate tax purposes, subject to contrary provisions of an
applicable estate tax treaty.
 
    BACKUP WITHHOLDING AND INFORMATION REPORTING.  Payments on the notes made by
Net.B@nk or any paying agent of Net.B@nk and payments of dividends on the common
stock to certain noncorporate Non-U.S. Holders generally should be subject to
information reporting and possibly to "backup withholding" at a rate of 31%.
Information reporting and backup withholding do not apply, however, to payments
made outside the United States by Net.B@nk or a paying agent on a note or to
payments of dividends on the common stock if the certification described under
"Non-U.S. Holders--The Notes" above is received, provided in each case that the
payer does not have actual knowledge that the Holder is a U.S. Holder.
 
    Payment of proceeds from a sale of a note or the common stock to or through
the U.S. office of a broker is subject to information reporting and backup
withholding unless the Non-U.S. Holder certifies as to its non U.S. status or
otherwise establishes an exemption from information reporting and backup
withholding. Payment outside the United States of the proceeds of the sale of a
note or the common stock to or through a foreign office of a "broker" (as
defined in applicable U.S. Treasury Regulations) should not be subject to
information reporting or backup withholding. However, unless the broker has
documentary evidence in its records that the beneficial owner is not a U.S.
Holder and certain other conditions are not met or the beneficial owner
otherwise establishes an exemption, US information reporting, but not backup
withholding, generally will apply to a payment made outside the United States of
the proceeds of a sale a note or the common stock through an office outside the
United States of a broker if the broker (1) is a U.S. person; (2) derives 50% or
more of its gross income from the conduct of a U.S. trade or business; (3) is a
"controlled foreign corporation" for U.S. federal income tax purposes; or (4)
with respect to payments made after December 31, 1999, is a foreign partnership,
if at any time during its taxable year, one or more of its partners are U.S.
persons, as defined in U.S. Treasury Regulations, who in the aggregate hold more
than 50% of the income or capital interest in the partnership or if, at any time
during its taxable year, such foreign partnership is engaged in a U.S. trade or
business.
 
    The U.S. Treasury Department has recently finalized regulations regarding
withholding and information reporting (the "Final Regulations") which will
generally be effective for payments made after December 31, 1999. The Final
Regulations do not significantly alter the substantive withholding and
information reporting requirements but would alter the procedures for claiming
the benefits of an income tax treaty and change the certification procedures
relating to the receipt by intermediaries of payments on behalf of the
beneficial owner of shares of notes or common stock. Non-U.S. Holders should
consult their own tax advisors regarding the effect, if any, of the Final
Regulations.
 
    THE U.S. FEDERAL INCOME TAX AND ESTATE TAX DISCUSSION SET FORTH ABOVE IS
INTENDED FOR GENERAL INFORMATION ONLY AND MAY NOT BE APPLICABLE TO A PARTICULAR
HOLDER'S SITUATION. PERSONS CONSIDERING A PURCHASE OF THE NOTES SHOULD CONSULT
THEIR OWN TAX ADVISORS REGARDING THE PARTICULAR TAX CONSEQUENCES OF PURCHASING,
OWNING AND DISPOSING OF THE NOTES AND THE COMMON STOCK, INCLUDING THE TAX
CONSEQUENCES UNDER STATE, LOCAL OR FOREIGN LAWS AND OTHER TAX LAWS AND THE
POSSIBLE EFFECTS OF CHANGES (POSSIBLY INCLUDING RETROACTIVE CHANGES) IN U.S.
FEDERAL AND OTHER TAX LAWS.

    The underwriting agreement provides that the obligations of the several
underwriters to purchase and accept delivery of the notes offered by this
prospectus are subject to approval by their counsel of certain legal matters and
to other conditions customary in a firm commitment public offering. The
underwriters are required to purchase and pay for the entire principal amount of
the notes offered by this prospectus, except for the principal amount of notes
covered by the over-allotment option described below, if any are purchased.
 
    The underwriters propose to offer the notes to the public at the offering
price listed on the cover page of this prospectus and to securities dealers,
including the underwriters, at the same price less a concession of not more than
$    per $1,000 principal amount of notes. The underwriters may allow, and the
selected dealers may reallow, a concession not in excess of $    per $1,000
principal amount of the notes to other brokers and dealers. After the completion
of this offering, the offering price and other selling terms may be changed by
the underwriters. However, no change shall alter the amount of proceeds, as
listed on the cover page of this prospectus, to be received by us.
 
    We have granted the underwriters an option, exercisable within 30 days after
the date of this prospectus, to purchase up to an additional $15,000,000
aggregate principal amount of the notes. The underwriters may exercise the
option only to cover over-allotments, if any, made in connection with this
offering. To the extent that the underwriters exercise the option, each
underwriter will become obligated to purchase its pro rata portion of the
additional principal amount of the notes based on the underwriter's percentage
underwriting commitment in the offering, which is indicated in the preceding
table. If purchased, the additional principal amount of the notes will be sold
by the underwriters on the same terms as those on which they are selling the
initial $100,000,000 principal amount of the notes.
 
   
    We estimate that our share of the total expenses of this notes offering,
excluding the estimated underwriting discounts and commissions, will be
approximately $      . We have agreed to indemnify the underwriters against
certain liabilities, including liabilities under the Securities Act of 1933, or
to contribute to payments that the underwriters may be required to make in
connection with these liabilities.
    
 
    Other than in the United States, no action has been taken by us or the
underwriters that would permit a public offering of the notes offered by this
prospectus in any jurisdiction which requires action for that purpose. The notes
offered by this prospectus may not be offered or sold, directly or indirectly,
nor may this prospectus or any other offering material or advertisements be
distributed or published in any jurisdiction, except under circumstances that
will ensure compliance with the applicable rules and regulations of the
jurisdiction. Persons holding this prospectus are advised to inform themselves
about and to observe any restrictions relating to this offering and the
distribution of this prospectus. This prospectus does not constitute an offer to
sell or a solicitation of an offer to buy any securities offered by this
prospectus in any jurisdiction in which an offer or a solicitation is unlawful.
 
                                       89

    We and certain of our officers, directors and existing shareholders have
agreed that during the period beginning from the date of this prospectus and
continuing to and including the date 90 days after the date of the prospectus,
they will not, directly or indirectly, issue, sell, offer or agree to sell,
grant any option for the sale of, pledge, make any short sale, establish an open
"put equivalent position" within the meaning of Rule 16a-1(h) under the
Securities Exchange Act of 1934 or otherwise dispose of any shares of Net.B@nk's
common stock (or securities that are convertible into, exercisable for or
exchangeable for common stock), without the prior written consent of Bear,
Stearns & Co. Inc., except under limited circumstances.
 
    Certain persons participating in this offering may engage in passive market
making transactions in the common stock in accordance with Rule 103 of
Regulation M under the Securities Exchange Act of 1934. Rule 103 permits, upon
the satisfaction of certain conditions, underwriting and selling group members
participating in a distribution that are also registered Nasdaq market makers in
the security being distributed, or a related security, to engage in limited
passive market making transactions during the period when Regulation M would
otherwise prohibit the activity. In general, a passive market maker may not bid
for or purchase a security at a price that exceeds the highest independent bid
for those securities by a person that is not participating in the distribution
and must identify its passive market making bids on the Nasdaq electronic
inter-dealer reporting system. In addition, the net daily purchases made by a
passive market maker generally may not exceed 30% of the market maker's average
daily trading volume in the security for the two full consecutive calendar
months, or any 60 consecutive days ending within 10 days, immediately preceding
the date of filing of the registration statement of which this prospectus is a
part.
 
    In addition, the underwriters may maintain or stabilize the price of the
notes by bidding for or purchasing notes in the open markets, and may impose
penalty bids, under which selling concessions allowed to broker-dealers
participating in this offering are reclaimed if notes previously distributed in
this offering are repurchased in connection with stabilization transactions or
otherwise. The imposition of a penalty bid may also affect the price of the
common stock to the extent that it discourages resales of the notes. The
underwriters can make no representation as to the magnitude, duration or effect
of any stabilization or other transactions.
 
    The notes are a new issue of securities with no established trading market.
We have been advised by the underwriters that they intend to make a market in
the notes but are not obligated to do so and may discontinue market making at
any time without notice. No assurance can be given as to the liquidity of the
trading market for the notes.
 
    Each underwriter has represented and agreed that:
 
    (1) It has not offered or sold, and for up to six months following the
       consummation of this offering, will not offer or sell, any notes in the
       United Kingdom except to persons whose ordinary activities involve them
       in acquiring, holding, managing or disposing of investments (as principal
       or agent) for the purposes of their businesses or otherwise in
       circumstances which do not constitute an offer to the public in the
       United Kingdom for the purposes of the Public Offers of Securities
       Regulations 1995;
 
    (2) It has complied and will comply with all applicable provisions of the
       Financial Services Act 1986 with respect to anything done by it in
       relation to the notes in, from or otherwise involving the United Kingdom;
       and
 
    (3) It has only issued or passed on and will only issue or pass on, in the
       United Kingdom, any document received by it in connection with the issue
       or sale of the notes to a person who is of a kind described in Article
       11(3) of the Financial Services Act 1986 (Investment
       Advertisements)(Exemptions) Order 1996 or to a person to whom the
       document may otherwise lawfully be issued or passed on.

       broker-dealer;
 
    (3) Is not a member of the National Association of Securities Dealers, Inc.;

and other financial services for us for which they may receive advisory or
transaction fees, as applicable, plus out-of-pocket expenses, of the nature and
in amounts customary in the industry for these services. Bear, Stearns & Co.
Inc., Raymond James & Associates, Inc. and Kelton International Ltd.
participated in the public offering of our common stock on February 5, 1999 in
which we sold 7,290,000 shares.
 
    Concurrent with this notes offering, we are offering, by means of a separate
prospectus, 3,000,000 shares of our common stock, plus an additional 450,000
shares to cover over-allotments by the underwriters of that offering. The
completion of this notes offering and of the common stock offering do not depend
upon one another. The underwriters for the common stock offering are also the
underwriters for this notes offering. The underwriters will receive customary
compensation in connection with the common stock offering.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
 
Net.B@nk, Inc.
 
    We have audited the consolidated balance sheets of Net.B@nk, Inc. and its
subsidiary ("Net.B@nk") as of December 31, 1998 and 1997 and the related
consolidated statements of operations, shareholders' equity (deficit) and cash
flows for the years ended December 31, 1998 and 1997 and the period from
February 20, 1996 (date of incorporation) to December 31, 1996. These financial
statements are the responsibility of Net.B@nk'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, such consolidated financial statements present fairly, in
all material respects, the financial position of Net.B@nk as of December 31,
1998 and 1997, and the results of its operations and its cash flows for the
years ended December 31, 1998 and 1997 and the period from February 20, 1996
(date of incorporation) to December 31, 1996 in conformity with generally
accepted accounting principles.

1. ORGANIZATION AND BASIS OF PRESENTATION
 
    Net.B@nk, Inc. ("Net.B@nk") is a bank holding company that wholly owns the
outstanding stock of Net.B@nk, formerly Atlanta Internet Bank, a federal savings
bank. Net.B@nk, Inc. was incorporated as a Georgia corporation on February 20,
1996, for the primary purpose of forming and, ultimately, operating Net.B@nk.
During the period from February 20, 1996 to July 31,1997, pending regulatory
approval and the acquisition of a bank charter, Net.B@nk was operating as a
development stage enterprise under an agreement with Carolina First Bank
("CFB"), a wholly owned subsidiary of Carolina First Corporation ("CFC"),
whereby CFB agreed to hold and service the deposit accounts generated by the
Internet banking operations of Net.B@nk in exchange for 3,975,000 shares of
Net.B@nk's common stock valued at $3,840,000. In addition, during the period
from February 20, 1996 to July 31, 1997, Net.B@nk was a party to an agreement
with First Alliance/Premier Bancshares, Inc. ("First Alliance") pursuant to
which Net.B@nk had agreed to purchase the charter of First Alliance's
subsidiary, Premier Bank, $5 million of loans, $5 million of certificates of
deposit and $2 million in unimpaired capital for $2,150,000 in cash, 124,218
shares of Net.B@nk's common stock valued at $125,000 and $75,000 in additional
cash for reimbursement of direct out-of-pocket expenses.
 
    On July 11, 1997, the final regulatory approval from the Office of Thrift
Supervision ("OTS") was received. On July 31, 1997, Net.B@nk received
approximately $38.4 million in net proceeds from the sale of 10,500,000 shares
of its common stock in an Initial Public Offering (the "IPO") and consummated
its agreements with both First Alliance and CFB. As a result, Net.B@nk, a
federal savings bank, became a wholly owned subsidiary of Net.B@nk, Inc. On
February 10, 1999, Net.B@nk received net proceeds of approximately $105,000,000
from the sale of an additional 7,290,000 shares of its common stock in a public
offering.
 
2. ACCOUNTING POLICIES
 
    The accounting and reporting policies of Net.B@nk conform with generally
accepted accounting principles and with general practice within the banking
industry. The following is a summary of the more significant policies:
 
    CONSOLIDATION--The consolidated financial statements of Net.B@nk, Inc.
include the financial statements of Net.B@nk, Net.B@nk, Inc.'s wholly owned
subsidiary. All intercompany balances and transactions have been eliminated in
consolidation.
 
    USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS--The preparation
of financial statements in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that affect the
reported amounts of assets and 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.
 
    INTEREST RATE RISK--Net.B@nk's assets and liabilities are generally monetary
in nature and interest rate changes have an impact on Net.B@nk's performance.
Net.B@nk decreases the effect of interest rate changes on its performance by
striving to match maturities and interest sensitivity between loans,

investment securities, deposits, and other borrowings. However, a significant
change in interest rates, specifically the prime rate, could have a material
effect on Net.B@nk's results of operations.
 
    CASH AND CASH EQUIVALENTS--For purposes of reporting cash flows, cash and
cash equivalents include cash on hand, demand deposits due from banks, and
federal funds sold to banks.
 
    INVESTMENT SECURITIES AVAILABLE FOR SALE--Investment securities classified
as available-for-sale are carried at fair value. Unrealized holding gains or
losses, net of tax, on available-for-sale securities are reported as a net
amount in other comprehensive income. Gains and losses from dispositions are
based on the net proceeds and the adjusted carrying amounts of the securities
sold using the specific identification method. Any decreases in investment value
other than temporary declines would be recognized in operations. Premiums and
discounts are recognized in interest income using the interest method over the
period to maturity.
 
    DEFERRED FEES AND COSTS--Loan origination fees and certain direct
origination costs are capitalized and recognized as an adjustment of the yield
of the related loans.
 
    ALLOWANCE FOR LOAN LOSSES--The allowance for loan losses is maintained at a
level estimated to be adequate to provide for probable losses in the loan
portfolio. As the majority of Net.B@nk's portfolio is purchased, an estimate of
the loss inherent in the purchased portfolio is made and an allowance for loan
losses is recorded by adjusting the premium associated with the purchased loans.
Management determines the adequacy of the allowance based upon reviews of
individual loans, recent loss experience, current economic conditions, the risk
characteristics of the various categories of loans and other pertinent factors.
Loans deemed uncollectible are charged to the allowance. Provisions for loan
losses and recoveries on loans previously charged off are added to the
allowance.
 
    FURNITURE AND EQUIPMENT--Furniture and equipment are stated at cost less
accumulated depreciation. Depreciation is computed using the straight-line
method over the estimated useful life of each asset. Net.B@nk evaluates the
estimated useful lives of assets on a periodic basis to determine whether events
or circumstances warrant revised estimated useful lives or whether any
impairment exists. Management believes no impairment existed at December 31,
1998.
 
    BANK CHARTER--The value of the charter is being amortized on a straight-line
basis over 25 years. The carrying value of the charter is periodically reviewed
to assess recoverability based on expected undiscounted cash flows and operating
income of Net.B@nk. Impairment would be recognized in operating results if a
permanent diminution in value was expected. Net.B@nk also evaluates the
amortization period of the bank charter to determine whether events or
circumstances warrant revised estimates of the useful life. Management believes
that no impairment of the bank charter existed at December 31, 1998.
 
    INTEREST INCOME ON LOANS--Interest on loans is generally recorded over the
term of the loan based on the unpaid principal balance. Accrual of interest is
discontinued when either principal or interest becomes 90 days past due or when,
in management's opinion, collectibility of such interest is doubtful. In
addition, any previously accrued interest is reversed when the loan becomes 90
days past due.
 
    PREMIUM ON LOANS PURCHASED--Premiums on loans purchased from third parties
are capitalized and amortized over the average life of the loan as an adjustment
to yield. Such premiums are classified with the loan balance to which they
relate for financial reporting purposes.

2. ACCOUNTING POLICIES (CONTINUED)
    INCOME TAXES--Provisions for income taxes are based upon amounts reported in
the statements of income and include deferred taxes for net operating loss
carryforwards and temporary differences between financial statement and tax
bases of assets and liabilities using enacted tax rates for the year in which
the temporary differences are expected to reverse. Net.B@nk records a valuation
allowance when management believes it is more likely than not that deferred tax
assets will not be realized.
 
    NET INCOME (LOSS) PER SHARE--In February 1997, Statement of Financial
Accounting Standards 128, EARNINGS PER SHARE ("SFAS 128") was issued. SFAS 128
establishes standards for computing and presenting earnings per share
information for entities with publicly held common stock. In accordance with
SFAS 128, basic net income per share is computed based on the weighted average
number of common shares outstanding during the period. Diluted net income per
share is computed based on the weighted average number of common and potential
dilutive common shares outstanding during the period. All previously reported
per share amounts have been restated to conform to SFAS 128.
 
    RECLASSIFICATIONS--Certain reclassifications have been made to the 1996 and
1997 financial statements to conform to the 1998 presentation.
 
    UNAUDITED INTERIM FINANCIAL STATEMENTS--The financial statements as of March
31, 1998 and 1999 and for the three months ended March 31, 1998 and 1999, were
prepared on the same basis as the audited consolidated financial statements and,
in the opinion of management, include all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of the financial
position and results of operations for these periods. Certain information and
note disclosures normally included in the consolidated financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the rules and regulations relating to interim
financial statements. Operating results for the interim periods included herein
are not necessarily indicative of the results that may be expected for the
entire year.
 
    NEW ACCOUNTING PRONOUNCEMENTS--As of January 1, 1998, Net.B@nk adopted
Statement of Financial Accounting Standards 130, REPORTING COMPREHENSIVE INCOME
("SFAS 130"), and restated prior periods to conform to the presentation required
by SFAS 130. SFAS 130 establishes new rules for the reporting and display of
comprehensive income and its components. SFAS 130 requires unrealized gains or
losses, net of tax, on Net.B@nk's available-for-sale securities, which prior to
adoption were reported separately in shareholders' equity, to be included in
other comprehensive income. The adoption of SFAS 130 had no impact on Net.B@nk's
net income or shareholders' equity.
 
    As of April 1, 1998, Net.B@nk adopted Statement of Position 98-1, ACCOUNTING
FOR THE COSTS OF COMPUTER SOFTWARE DEVELOPED OR OBTAINED FOR INTERNAL USE ("SOP
98-1"). SOP 98-1 allows for the capitalization of costs related to the
development and implementation of software obtained for internal use including
materials, payroll, and interest costs once the criteria of the SOP have been
met. As of December 31, 1998, $592,402 of these related costs had been
capitalized.
 
    As of December 31, 1998, Net.B@nk adopted SFAS 131, DISCLOSURES ABOUT
SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION. SFAS 131 establishes annual
and interim reporting standards for an enterprise's business segments and
related disclosures about its products, services, geographic areas, and major
customers. The adoption of SFAS 131 had no effect on Net.B@nk's financial
statements for the year ended December 31, 1998 because Net.B@nk only has one
reportable segment-banking.

2. ACCOUNTING POLICIES (CONTINUED)
    In June 1998, Statement of Financial Accounting Standards 133, ACCOUNTING
FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES ("SFAS 133"), was issued. SFAS
133 establishes standards for derivative instruments and hedging activities and
requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. SFAS 133 is effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. The adoption of SFAS 133 is not expected to have
a significant effect on Net.B@nk's financial statements.
 
3. ACQUISITION
 
    Effective July 31, 1997, Net.B@nk acquired all of the outstanding stock of
Premier Bank, FSB for $2,150,000 in cash, 124,218 shares of Net.B@nk's common
stock valued at $125,000 and $75,000 in additional cash for reimbursement of
direct out-of-pocket expenses. The acquisition was accounted for as a purchase
and the bank charter was recorded at $350,000. This amount is being amortized
over 25 years. Revenues, net loss, and basic and diluted net loss per common
share and potential dilutive common share for Net.B@nk for the period from
February 20, 1996 to December 31, 1996 or for the year ended December 31, 1997
would not have been materially affected assuming the transaction had occurred on
February 20, 1996 and January 1, 1997, respectively.

    Net.B@nk considers a loan to be impaired when it is probable that it will be
unable to collect all amounts due according to the original terms of the loan
agreement. Net.B@nk measures impairment of a loan on a loan by loan basis.
Amounts of impaired loans that are not probable of collection are charged off
immediately. During the years ended December 31, 1997 and 1998, Net.B@nk had no
significant amount of impaired loans or nonaccrual loans. The amount of impaired
loans written off during the years ended December 31, 1997 and 1998 was $18,262
and $587,138, respectively. Net.B@nk had no restructured loans as of either
December 31, 1997 or 1998.
 
    Net.B@nk is a party to financial instruments with off-balance-sheet risk in
the normal course of its lending activities to meet the financing needs of its
customers. These financial instruments include commitments to extend credit and
lines of credit. Net.B@nk's exposure to credit loss in the event of
nonperformance by the other party to the financial instrument for commitments to
extend credit and standby letters of credit is represented by the contractual
amount of those instruments. Net.B@nk uses the same credit policies in making
these commitments as it does for on-balance-sheet instruments and evaluates each
customer's creditworthiness on a case-by-case basis. At December 31, 1997 and
1998, Net.B@nk had outstanding loan commitments of $8,332,568 and $47,617,700,
respectively.
 
    The amount of collateral obtained by Net.B@nk, if deemed necessary, for
these commitments, upon extension of credit, is based on management's credit
evaluation of the customer. Collateral held, if any, varies but may include
inventory, equipment, real estate, or other property. The accounting loss
Net.B@nk would incur if the borrower failed completely to perform according to
the terms of the contract and the collateral proved to be of no value is equal
to the face amount of the commitment.
 
7. LOAN ORIGINATION AGREEMENTS
 
    During the year ended December 31, 1998, Net.B@nk entered into separate
agreements with three unrelated third parties whereby Net.B@nk acts as a loan
originator on behalf of the third parties. Under the terms of the agreements,
the third parties are required to purchase all loans, including the related
servicing of these loans, originated by Net.B@nk, unless Net.B@nk elects to
retain the loans. As a result of the agreements, loans originated for the third
parties for which the purchase price has not yet been received are accounted for
as receivables.

</TABLE>
 
    During the year ended December 31, 1998, Net.B@nk, Inc. and its subsidiary,
Net.B@nk, entered into line of credit agreements with The Bankers Bank.
Net.B@nk, Inc. is a party to one such agreement and its subsidiary, Net.B@nk, is
a party to two such agreements. Under the terms of Net.B@nk, Inc.'s agreement
which expired on October 20, 1998, Net.B@nk, Inc. could borrow 50% of the
tangible equity of Net.B@nk, up to $17 million, using the stock of Net.B@nk as
collateral. Any amounts borrowed under this line had interest at a fixed rate of
8.00% per annum. During the year ended December 31, 1998, Net.B@nk, Inc.
borrowed and repaid $12 million under the line. Under the terms of the other two
agreements, the subsidiary, Net.B@nk, may borrow $5 million under an unsecured
general purpose line and 99% of the value of its investment securities under
another line. Both of the lines bear interest at 25 basis points above the
Federal Funds rate (5.00% at December 31, 1998). Under these agreements at
December 31, 1998, the subsidiary, Net.B@nk, had an outstanding borrowing of $20
million with no stated maturity secured by investment securities.
 
    As of March 31, 1999, the subsidiary, Net.B@nk, has borrowed $20 million
from the Federal Home Loan Bank ("FHLB") at a fixed rate of 4.43%. The borrowing
is callable at the two-year anniversary date. If not called at the two-year
date, the borrowing extends for an additional three years at 4.435%. Also, the
subsidiary, Net.B@nk, has borrowed $25 million from the Federal Home Loan Bank
at a fixed rate of 4.64%. The borrowing is callable at the two-year anniversary
date. If not called at the two-year date, the borrowing extends for an
additional eight years at 4.64%. These borrowings are secured by Net.B@nk's
investment securities.

    Rent expense for the period from February 20, 1996 (date of incorporation)
to December 31, 1996, and for the years ended December 31, 1997 and 1998, was
$17,850, $91,868, and $110,011, respectively.
 
11. INCOME TAXES
 
    Net.B@nk provides deferred income taxes for net operating loss carryforwards
and for temporary differences between financial statement and tax bases of
assets and liabilities using enacted tax rates in effect for the year in which
the temporary differences are expected to reverse. As of December 31, 1998,
Net.B@nk had state and federal net operating loss carryforwards of $6,182,993
which will expire in 2012 and 2011, if not utilized.
 
    Net.B@nk did not incur any income taxes during 1996 and 1997. For the year
ended December 31, 1998, Net.B@nk's income tax benefit results from the reversal
of the valuation allowance as of December 31, 1997, relating to net operating
loss carryforwards offset by taxable income for the period. As Net.B@nk achieved
profitability in 1998, management now believes that it is more likely than not
that such assets will be realized, and thus, reversed the valuation allowance in
accordance with SFAS 109, ACCOUNTING OF INCOME TAXES.

13. EMPLOYEE BENEFIT PLAN
 
    Effective December 31, 1997, Net.B@nk adopted a 401(k) plan (the "Plan")
which covers substantially all of its employees. Net.B@nk, at its discretion,
matches 25% of employee contributions to the Plan, up to a maximum Company
contribution of 1% of an employee's compensation. Net.B@nk expensed $10,100
during 1998 related to the plan.
 
14. SHAREHOLDERS' EQUITY
 
    On March 17, 1997, Net.B@nk declared a 33.125 for one split of its common
stock effected in the form of a stock dividend payable on the effective date of
the initial public offering. All references to share and per share amounts
reflect the split. Also, additional paid-in capital has been charged and common
stock has been credited retroactively with $12,116 to reflect the stock split.
 
    On February 10, 1999, Net.B@nk received net proceeds of approximately
$105,000,000 from the sale of 7,290,000 shares of its common stock in a public
offering.
 
    On April 13, 1999, Net.B@nk declared a three-for-one split of its common
stock effected in the form of a stock dividend payable on May 14, 1999 to
shareholders of record as of the close of business on April 23, 1999. All
references to share and per share amounts have been retroactively adjusted to
reflect the split.
 
    Under current OTS regulations, Net.B@nk may pay dividends and make other
capital distributions after giving notice to the Office of Thrift Supervision.
 
15. STOCK OPTIONS
 
    Net.B@nk has a 1996 Stock Incentive Plan (the "Plan"), which provides that
key employees, officers, directors, and consultants of Net.B@nk may be granted
nonqualified and incentive stock options to purchase shares of common stock of
Net.B@nk, derivative securities related to the value of the common stock, or
cash awards. Previously, the Plan limited the number of shares which could be
awarded to 1,800,000. Effective with shareholder approval on April 22, 1999, the
Plan was amended to increase the total number of shares reserved for the Plan to
3,750,000. Generally, the options expire ten years from the date of the grant.

16. EARNINGS PER SHARE
 
    Basic and diluted net income (loss) per common and potential common share
have been calculated based on the weighted average number of shares outstanding
in accordance with SFAS 128. In accordance with SFAS 128, the following schedule
reconciles the numerators and denominators of the basic and diluted net income
per common and potential common share. The only periods presented relate to
those with net income as diluted securities would be anti-dilutive to periods
with a net loss. Net.B@nk had options to purchase common stock outstanding of
49,686 and 1,099,368 at December 31, 1996 and 1997, respectively.

17. CAPITAL ADEQUACY
 
    Net.B@nk is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure of Net.B@nk to meet minimum capital
requirements can initiate certain mandatory and possibly additional
discretionary actions by regulators that, if undertaken, could have a direct
material effect on Net.B@nk's consolidated financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
Net.B@nk must meet specific capital guidelines that involve quantitative
measures of Net.B@nk's assets, liabilities, and certain off-balance-sheet items
as calculated under regulatory accounting practices. Net.B@nk's capital amounts
and classifications are also subject to qualitative judgments by the regulators
about components, risk weightings, and other factors. In addition, under
regulatory guidelines, Net.B@nk may not pay a dividend to Net.B@nk, Inc. if
doing so would cause Net.B@nk to be less than adequately capitalized, as defined
below.
 
    Quantitative measures established by regulation to ensure capital adequacy
require Net.B@nk to maintain minimum amounts and ratios set forth in the table
below. Net.B@nk's regulatory agency, the OTS, requires Net.B@nk to maintain
minimum ratios of tangible capital to tangible assets of 1.5%, core capital to
tangible assets of 3.0%, and total risk-based capital to risk-weighted assets of
8.0%. Management believes, as of December 31, 1998, that Net.B@nk meets all the
capital adequacy requirements to which it is subject.
 
    As of December 31, 1998, the most recent notification from the OTS
categorized Net.B@nk as well capitalized under the regulatory framework for
prompt corrective action. To be well capitalized Net.B@nk must maintain minimum
total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in
the table. There are no conditions or events since that notification that
management believes would have changed the institution's category.
 
    Net.B@nk's actual capital amounts and ratios as of December 31, 1997 and
1998, are as follows (dollars in thousands):

criteria may be retained by the third party, who in turn will pay Net.B@nk a
flat fee per loan originated. The third party will also perform servicing on
Net.B@nk's portfolio for a monthly fee. In addition, Net.B@nk will also pay the
third party a $300,000 setup fee for reimbursement of out-of-pocket expenses

</TABLE>
 
    The carrying amounts of cash and due from banks and federal funds sold are a
reasonable estimate of their fair value due to the short-term nature of these
financial instruments. The fair value of investment securities and loans is
based on quoted market prices and dealer quotes. The fair value of time deposits
and other borrowed funds is estimated by discounting the future cash flows using
Net.B@nk's current interest rates for such financial instruments.
 
    As required by SFAS 107, demand deposits are shown at their face value. No
additional value has been ascribed to core deposits, which generally bear a low
rate of or no interest and do not fluctuate in response to changes in interest
rates.
 
    The fair value estimates presented herein are based on pertinent information
available to management at December 31, 1998 and 1997. Although management is
not aware of any factors that would significantly affect the estimated fair
value amounts, such amounts have not been comprehensively revalued for purposes
of these financial statements since that date and, therefore, current estimates
of fair value may differ significantly from the amounts presented herein.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Our Bylaws contain certain indemnification provisions providing that
directors, officers and employees or agents of Net.B@nk will be indemnified
against expenses actually and reasonably incurred by them if they are successful
on the merits of a claim or proceeding.
 
    When a case or dispute is not ultimately determined on its merits (i.e., it
is settled), the indemnification provisions provide that Net.B@nk will indemnify
directors when they meet the applicable standard of conduct. The applicable
standard of conduct is met if the director acted in good faith and in a manner
he or she reasonably believed to be in or not opposed to the best interests of
Net.B@nk, and with respect to an employee benefit plan, for a purpose the
director believed in good faith to be in the interests of the participants and
beneficiaries of the plan. The standard of conduct with respect to any criminal
action or proceeding is met if the director had no reasonable cause to believe
his or her conduct was unlawful. Whether the applicable standard of conduct has
been met is determined by the Board of Directors, the shareholders or
independent legal counsel in each specific case.
 
    Net.B@nk can also provide for greater indemnification than that set forth in
the Bylaws if it chooses to do so, subject to approval by Net.B@nk's
shareholders. Net.B@nk may not, however, indemnify a director for liability
arising out of circumstances which constitute exceptions to limitation of a
director's liability for monetary damages.
 
    The indemnification provisions of the Bylaws specifically provide that
Net.B@nk may purchase and maintain insurance on behalf of any director against
any liability asserted against such person and incurred by him or her in any
such capacity, whether or not Net.B@nk would have had the power to indemnify
against such liability.
 
    In addition, Article IV of Net.B@nk's Articles of Incorporation, subject to
certain exceptions, eliminates the potential personal liability of a director
for monetary damages to Net.B@nk and to the shareholders of Net.B@nk for breach
of a duty as a director. There is no elimination of liability for (a) a breach
of duty involving appropriation of a business opportunity of Net.B@nk, (b) an
act or omission not in good faith or involving intentional misconduct or a
knowing violation of law, (c) a transaction from which the director derives an
improper material tangible personal benefit, or (d) as to
 
                                      II-1
<PAGE>
any payment of a dividend or approval of a stock repurchase that is illegal
under the Georgia Business Corporation Code. The Articles of Incorporation do
not eliminate or limit the right of Net.B@nk or its shareholders to seek
injunctive or other equitable relief not involving monetary damages.

    Registrant's Registration Statement on Form S-1 (Regis. No. 333-23717).
 
ITEM 17. UNDERTAKINGS.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the forgoing provisions described in Item 15 above, 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
 
                                      II-2
<PAGE>
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:
 
    (a) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    (b) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
    (c) The undersigned registrant hereby undertakes that, for the purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange
Act (and, where applicable, each filing of an employee benefit plan's annual
report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in the registration statement 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.
 
    (d) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in 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.
 
    (e) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
