<PAGE>

                              SUMMARY INFORMATION

     We provide a wide range of secure Internet services that incorporate high-
bandwidth connectivity and enable secure electronic business over the Internet.
Our services are offered for a fixed monthly fee on an annual subscription basis
and include secure hosting and Internet connectivity services that enable secure
connectivity between a corporate network and the Internet and secure virtual
private networking services that enable remote users and wide-area networks to
securely communicate enterprise-wide and over the Internet.

     Our Internet services allow our customers to avoid the risks associated
with traditional approaches to Internet security.  Customers can also avoid
extensive costs associated with implementing an in-house solution, including
set-up costs for security and systems design, hardware, software, Internet
access services provided by Internet Service Providers, as well as labor and
ongoing costs for telecommunications, staffing, maintenance and upgrades.

     The foundation of our solution is our Heuristic Defense Infrastructure, an
Internet security approach we developed to continuously manage and monitor
Internet traffic to and from customer networks in order to respond in real-time
to security threats.  The Heuristic Defense Infrastructure consists of a multi-
layered defensive architecture and around-the-clock security operations
delivered through geographically dispersed customer centers called Network
Security Centers that are connected to customer networks via dedicated, high-
speed data lines.  Our solution aggregates the experience gained from protecting
each customer against attacks and leverages such experience for the collective
benefit of all customers.  The Heuristic Defense Infrastructure offers benefits
over other security approaches by eliminating single points of failure,
enhancing attack detection, delivering real-time defenses, and adapting
continuously to external conditions.  Customers can concentrate on their core
business because the secure infrastructure for electronic commerce is provided
by Pilot.

                                 RISK FACTORS

     You should carefully consider the following and other information contained
in this prospectus before making an investment decision. If any of the events or
circumstances described in the following risks actually occurs, our business,
financial condition, or results of operations could be materially harmed. In
that case, the trading price of our common stock could decline, and you may lose
all or part of your investment.

     You should consider carefully whether an investment in Pilot is an
appropriate investment for you. We do not intend to issue any dividends in the
foreseeable future, so the only purpose of investment in Pilot's shares is in
expectation of a potential increase in the shares' value. Because of the risks
mentioned here, and other risks not mentioned specifically here, it is possible
that Pilot's shares will decline in value in the future.  If you cannot afford
to lose the full value of your investment, in either the short or long term,
purchasing Pilot shares is not appropriate for you.

If our existing financing sources and other sources are not available, we may
not have sufficient cash to satisfy our working capital requirements.

     If we are unable to generate sufficient cash flow from operations, or are
unable to obtain additional equity or equipment lease financing, we may be
required to sell assets, scale down our operations and expansion plans,
refinance all or a portion of our existing indebtedness or obtain other sources
of financing earlier than planned, any of which could have a material adverse
impact on our financial condition and ability to continue operations.  Our
working capital requirements depend upon several factors, including:

                                       2
<PAGE>

     .    plans to incur substantial additional capital expenditures primarily
          for additions to and expansions of our Network Security Centers;

     .    developing, acquiring or licensing new applications and technologies;
          and

     .    the level of resources that we devote to our sales and marketing
          activities.

     In addition to the $30.0 million in aggregate equity investment in June
2000 and December 1999 and $8.0 million credit facility completed in November
1999, we believe that we will require additional equity financing.  However, we
may not be successful in generating sufficient levels of cash from operations or
in obtaining financing on commercially reasonable terms, or at all.

We are experiencing operating losses and may not achieve profitability.

     We have experienced operating losses and negative cash flows from
operations in each quarterly and annual period since we began operations in 1993
and expect to continue to experience losses for the foreseeable future.  As of
March 31, 2000, we had an accumulated deficit of approximately $53.0 million.
We experienced an increase in net loss in fiscal 1998, 1999 and 2000.  The
revenue and income potential of our business and market is unproven, and our
limited operating history makes an evaluation of our prospects difficult.

     Failure of our services to achieve market acceptance would have a material
adverse effect on our revenues and results of operations.  We cannot assure you
that we will ever achieve profitability.

Our stock price and our quarterly operating results are highly volatile, which
may impair our ability to raise money and cause our investors to lose money.

     Our results of operations may not meet the expectations of securities
analysts or investors, which could cause the market price of our common stock to
decline.  For example, a relatively large portion of our expenditures are fixed
in the short-term, and our success is substantially dependent on the continued
growth in our customer base and the retention of our customers for sufficient
periods to provide returns on our investment.  We derive revenue from our
customers primarily through initial setup fees and ongoing monthly service
charges.  For each new customer, we incur costs in anticipation of the
customer's decision to use our services and in advance of the receipt of
sufficient revenues to repay these costs and provide a return on our investment.
Our customers may decide not to maintain or renew their commitments to use our
services.

     In addition, we typically experience a lengthy sales cycle for our
services, particularly given the importance to customers of adequately securing
Internet connectivity for electronic commerce and the need to educate them
regarding the requirements for effective network security.  Changes in the rate
of growth in our customer base, customer renewal rates and the sales cycle for
our services, have caused, and we expect will continue to cause for the
foreseeable future, significant fluctuations in our results of operations on a
quarterly and an annual basis.

The conversion of our Series A convertible preferred stock may have a dilutive
impact on our security holders.

     The number of shares of common stock that may ultimately be issued upon
conversion of shares of our Series A convertible preferred stock is presently
undeterminable because the conversion price of the Series A convertible
preferred stock is based in part on the price of the common stock at the time of
the conversion.  The conversion price of the Series A convertible preferred
stock is initially fixed at

                                       3
<PAGE>

$18.266 per share. The conversion of all of the 15,000 shares of Series A
convertible preferred stock outstanding would result in the issuance of
approximately 821,198 shares of common stock. This represents about 5.5% of our
outstanding common stock based on the number of shares outstanding as of June
28, 2000.

     The terms of the Series A convertible preferred stock provide that the
number of shares issuable upon conversion of the Series A convertible preferred
stock will increase as the price of our common stock drops.  For example, if the
price of our common stock declines and the conversion price falls to $10.00 per
share, assuming all 15,000 shares of Series E preferred stock were converted, we
would issue approximately 1,500,000 shares of common stock.  This would
represent approximately 9.9% of our outstanding common stock based on the number
of shares outstanding as of June 28, 2000.  Any increased issuance of our common
stock resulting from a lowered conversion price could place additional downward
pressure on the price of our common stock generally.  A downward movement in the
price of our common stock could result in the loss of substantially all your
investment.

We rely on third parties to deliver our Heuristic Defense Infrastructure and
generate revenues.

     In fiscal 2000, we sold technology and consulting services to enable two
telecommunications carriers to embed our Heuristic Defense Infrastructure in
several of their security centers.  As part of the relationship with these
carriers, we will receive a recurring fee based on the total revenue generated
through the Heuristic Defense Infrastructure.  In exchange, we will provide
security monitoring for network traffic using the Heuristic Defense
Infrastructure.  While the telecommunications carriers have committed capital
and operational resources to these projects, as of July 24, 2000, none of these
third-party centers are operational.  There are no guarantees that these centers
will ever be operational or that they will generate material revenues or
earnings for us.  To the extent one or both of the carriers elect not to proceed
with using the Heuristic Defense Infrastructure or if the implementation is
materially delayed, there could be a material adverse effect on our ability to
expand operations and improve our operating results and financial condition.

We may not be able to prevent unauthorized access to our customers' networks.

     Despite our focus on Internet security, we may not be able to stop
unauthorized attempts, whether made unintentionally or by computer "attackers,"
to gain access to or disrupt the network operations of our customers.
Accordingly, our success is substantially dependent on the continued confidence
of our current and potential customers that we provide superior network security
protection.  Any failure by us to stop unauthorized access from the Internet or
disruptions to related Internet operations of our customers could materially
harm such customers and us.

     Although we generally limit warranties and liabilities relating to security
in our customer contracts, our customers may seek to hold us responsible for any
losses suffered as a result of unauthorized access to customers' network systems
from the Internet.  This could result in liability to us, which could have a
material adverse effect upon our business.  Moreover, computer attackers from
the Internet could infiltrate our network and sabotage our network or services
by creating bugs or viruses.  Any adverse publicity resulting from unauthorized
access could deter future customers from using our services and could cause
current customers to cease using our services, which could have a material
adverse effect upon our business.

We may not be able to effectively manage our growth.

     Any inability on our part to manage effectively our expansion, including
any disruption of service to current customers, may have a material adverse
effect upon our business.  Our current plans are to

                                       4
<PAGE>

expand domestically and internationally by adding, or partnering with third
parties that add, Network Security Centers in new locations and expanding
Network Security Centers in existing locations. This expansion will require us
or our partners to expend substantial resources for leases and improvements of
facilities, purchases of equipment, implementation of multiple
telecommunications connections and hiring of network, administrative, customer
support, and sales and marketing personnel. Furthermore, it may cause the
interruption of service to current customers.

     In addition, we have recently hired large numbers of new employees.  This
growth has placed, and may continue to place, a significant strain on our
financial, management, operational and other resources.

The market we serve is highly competitive and we may lose market share to
current or future competitors.

     We may not have the resources or expertise to compete successfully in the
market we serve.  The market we serve is new, rapidly evolving, highly
competitive and largely undefined.  There are few barriers to entry, and we
expect that we will face increasing competition from existing competitors and
new market entrants in the future.

     We compete with a broad range of products and services.  Many of our
competitors have substantially greater financial, technical and marketing
resources, larger customer bases, longer operating histories, greater name
recognition and more established relationships in the industry than we do.  As a
result, certain of these competitors may be able to develop and expand their
network infrastructures and service offerings more quickly, adapt to new or
emerging technologies and changes in customer requirements more quickly, take
advantage of acquisition and other opportunities more readily, devote greater
resources to the marketing and sale of their products and adopt more aggressive
pricing policies than us.

     In addition, we believe that the businesses with which we compete are
likely to encounter consolidation in the near future, which could result in
increased price and other competition that could have a material adverse effect
on our ability to compete in our market.

If our systems fail, our business will suffer.

     Despite existing and planned precautions by us, the occurrence of a natural
disaster or other unanticipated problems at one or more of our Network Security
Centers could result in interruptions in the services we provide.  Our success
depends on the excellence of security protection and uninterrupted operation of
our network infrastructure.  Any damage to or failure of our systems or those of
our service providers could result in reductions in, or terminations of,
services supplied to our customers.  These reductions or terminations in service
could materially and adversely impact our customers, which could cause our
customers to elect not to use our services.

                                       5
<PAGE>

The expansion of our international operations exposes us to risks.

     A key component of our long-term strategy is to expand into international
markets.  If the revenue we generate from any international Network Security
Center is not adequate to offset the expense of establishing and maintaining any
such international operation, our financial condition could be materially
adversely affected.

If our growth exceeds our capacity to transmit data, our business will suffer.

     If we fail to achieve or maintain high capacity data transmission, customer
demand for our services could decline significantly.  We must continue to expand
and adapt our network infrastructure as the number of customers and the amount
of information they wish to transmit increases, and as customer requirements
change.  The expansion and adaptation of our telecommunications infrastructure
will require substantial financial, operational and management resources.
Because the deployment of our services to date has been limited, the ability of
our network to connect and manage a substantially larger number of customers at
high transmission speeds is as yet unknown and our network's ability to operate
with higher customer levels while maintaining superior performance is unproven,
we may not be able to expand or adapt our telecommunications infrastructure to
meet additional demand or our customers' changing requirements.

We depend on third party network infrastructure providers to deliver our
services.

     Our business relies on Internet exchange points, or IXPs, to transmit our
customers' traffic to and from the Internet.  If the carriers that operate these
IXPs discontinue their support of the peering points or refuse to offer services
to us and no alternative providers emerge, or such alternative providers
increase the cost of utilizing the IXPs, our ability to transmit network traffic
will be significantly constrained.  Our success depends upon these Internet
infrastructure providers.

     In addition, we rely on a number of private peering interconnections (i.e.,
arrangements among access providers to carry traffic of each other) to deliver
our services.  If we are unable to access alternative networks on a cost-
effective basis to distribute our customers' content or pass through any
additional costs of utilizing these networks to our customers, our business will
be materially harmed.

Our ability to deliver our services will suffer if we are unable to obtain
components available in limited quantities or from single source.

     If we fail to obtain hardware or software components that we require on a
timely basis and at an acceptable cost, our ability to provide our services will
suffer.  We are dependent on other companies to supply certain key components of
our telecommunications infrastructure and system and network management
solutions that, in the quantities and quality demanded by us, are available only
from sole or limited sources.

     We also intend to develop alternative distribution and lead generation
channel partners for our services, such as systems integration firms and
bandwidth providers.  If we fail to develop these channel partners, our ability
to generate increased revenues will be materially and adversely affected.

If we are not able to enhance our products to adapt to rapid technological
change, our services may not achieve market acceptance.

     Our success depends, in part, on our ability to offer services that
incorporate leading technology, address the increasingly sophisticated and
varied needs of our current and prospective customers and

                                       6
<PAGE>

respond to technological advances and emerging industry standards and practices
on a timely and cost-effective basis. The market for our services is
characterized by rapidly changing and unproven technology, evolving industry
standards, changes in customer needs, emerging competition and frequent new
service introductions. Future advances in technology may not be beneficial to,
or compatible with, our business or we may not be able to incorporate such
advances on a cost-effective and timely basis into our business. We believe that
our ability to compete successfully is also dependent upon the continued
compatibility and interoperability of our services with products, services and
architectures offered by various vendors as part of our services. These products
may not be compatible with our infrastructure or these products may not
adequately address changing customer needs. In addition, products, services or
technologies developed by others may render our services uncompetitive or
obsolete, which would materially harm our business.

If we are not able to attract and retain qualified personnel, our business will
not be able to grow.

     Our success depends in significant part upon the continued services of our
key technical, sales and senior management personnel, including our President
and Chief Executive Officer, Marketta Silvera, and our Chief Technology Officer,
Thomas Wadlow.  Any officer or employee of ours can terminate his or her
relationship with us at any time.  The loss of the services of one or more of
our key employees or our failure to attract additional qualified personnel could
have a material adverse effect on our business.

The law governing the liability of on-line service providers is unsettled and
exposes us to risks.

     The law relating to the liability of on-line service companies such as
Pilot and Internet access providers for information carried on or disseminated
through their networks is currently unsettled.  It is possible that claims could
be made against us under both United States and foreign law for defamation,
negligence, copyright or trademark infringement, or other theories based on the
nature and content of the materials disseminated through our networks.  The
imposition of liability upon us for information carried on or disseminated
through our systems could require us to implement measures to reduce our
exposure to such liability, which may require the expenditure of substantial
resources, or to discontinue certain service or product offerings.

Our proprietary rights may be inadequately protected and infringement claims
could harm our competitive position.

     We rely on a combination of copyright, trademark, patent, service mark and
trade secret laws and contractual restrictions to establish and protect and
proprietary rights in technology underlying our services.  We may fail to obtain
patents or trademarks from currently pending or any future applications, and any
patents or trademarks that may be issued or granted may not be sufficient in
scope or strength to provide meaningful protection or any commercial advantage
to us.  In addition, the laws of certain foreign countries may not protect our
products, services or intellectual property rights to the same extent as do the
laws of the United States.

     The contractual arrangements and other steps we take to protect our
intellectual property may not prove sufficient to prevent infringement of or

                             SELLING STOCKHOLDERS

     On June 28, 2000, we entered into a securities purchase agreement with one
of the selling stockholders, Marshall Capital Management, Inc., pursuant to
which we sold 15,000 shares of our Series A convertible preferred stock to
Marshall Capital for $15,000,000. Marshall Capital also acquired a warrant to
purchase 256,621 shares of common stock with an exercise price of $17.536 per
share in connection with the transaction. This prospectus covers the common
stock issuable upon conversion of the 15,000 shares of Series A convertible
preferred stock, potential dividends paid in common stock, and common stock
issuable upon exercise of the warrant issued to Marshall Capital. The terms of
the securities purchase agreement and the Series A convertible preferred stock
are summarized below under "Description of Capital Stock - Preferred Stock."

     We are registering the shares being offered by the other two selling
stockholders, Greyrock Capital and Primus Telecommunications Group,
Incorporated, pursuant to our obligations under an investors' rights agreement
to which they are parties.  Greyrock Capital may acquire the shares it is
offering upon exercise of a warrant to purchase common stock we issued to
Greyrock in November 1999 in connection with a credit facility we established
with Greyrock at that time.  Primus acquired the shares it is offering in a
December 1999 private placement.

     Other than ownership of our securities, none of the selling stockholders
has had a material relationship with us within the past three years.

Registration Rights Agreement.

     On June 28, 2000, we also entered into a registration rights agreement with
Marshall Capital.  This agreement requires that we register shares of common
stock sufficient to effect the conversion of 15,000 shares of Series A
convertible preferred stock, any dividends paid in common stock to the holders
of the Series A convertible preferred stock, and the exercise of the warrant
issued to Marshall Capital.  We will also prepare and file any amendments and
supplements to the registration statement as may be necessary in accordance with
the Securities Act, and the rules and regulations promulgated thereunder.

     We are subject to penalties if we do not fulfill our obligations under the
registration rights agreement.  For example, the registration statement must be
filed 30 days from the issue date of the Series A convertible preferred stock.
Furthermore, the registration statement covering the resale of the common stock
must be effective within 90 days after the date of the registration rights
agreement or, if earlier, 60 after the filing date of the registration statement
of which this prospectus forms a part.  Finally, our stock must be listed on the
American Stock Exchange, the New York Stock Exchange, or the Nasdaq Stock
Market.  Potential penalties for failing to meet our obligations under the
registration rights agreement include payments equal to approximately 1.5% of
the purchase price of the Series A convertible preferred stock per month until
the registration statement is either filed or effective and reductions in the
conversion price applicable to the Series A convertible preferred stock.

     We have agreed to indemnify the selling stockholders against liabilities

provide that we will reimburse them for expenses they incur in connection with
investigating or defending against claims based upon untrue statements (or
alleged untrue statements) or omissions (or alleged omissions) of material facts
in our filings with the SEC.  In addition, we will indemnify the selling
stockholders against claims based on any violation (or alleged violation) by us
of the Securities Act or other federal or state securities regulations.

     As explained below under "Plan of Distribution," we have agreed to bear
certain expenses (other than broker discounts and commissions, if any) in
connection with the registration statement.


                                USE OF PROCEEDS

     We will not receive any of the proceeds from the sale of the shares offered
by this prospectus. The selling stockholders will receive all such proceeds.

                              PLAN OF DISTRIBUTION

     All or a portion of the shares offered hereby by the selling stockholders
may be delivered and/or sold in transactions from time to time on the over-the-
counter market, on the Nasdaq National Market, in negotiated transactions, sales
on any market where our stock is traded, any other legal method of disposition,
delivery of shares in settlement of option/short sales transactions or other
derivative transactions, block trades, or a combination of such methods of sale,
at market prices prevailing at the time, at prices related to such prevailing
prices or at negotiated prices.  The selling stockholders may effect such
transactions by selling to or through one or more broker-dealers, and such
broker-dealers may receive compensation in the form of underwriting discounts,
concessions or commissions from the selling

                                      10
<PAGE>

stockholders. Any broker-dealer that participates in the distribution may under
certain circumstances be deemed to be an "underwriter" within the meaning of the
Securities Act, and any commissions such broker-dealer receives and any profits
it realizes on the resale of shares may be deemed to be underwriting discounts
and commissions under the Securities Act. We have agreed to indemnify the
selling stockholders with respect to the shares offered hereby against certain
liabilities, including, without limitation, certain liabilities under the
Securities Act, or, if such indemnity is unavailable, to contribute toward
amounts required to be paid in respect of such liabilities.

     Any broker-dealer participating in such transactions as agent may receive
commissions from the selling stockholders (and, if the selling stockholders act
as agent for the purchaser of such shares, from such purchaser).  Broker-dealers
may agree with the selling stockholders to sell a specified number of shares at
a stipulated price per share, and, to the extent such a broker-dealer is unable
to do so acting as agent for the selling stockholders, to purchase as principal
any unsold shares at the price required to fulfill the broker-dealer commitment
to the selling stockholders.  Broker-dealers who acquire shares as principal may
thereafter resell such shares from time to time in transactions (which may
involve crosses and block transactions and which may involve sales to and
through other broker-dealers, including transactions of the nature described
above) in the over-the-counter market, in negotiated transactions or otherwise
at market prices prevailing at the time of sale or at negotiated prices, and in
connection with such resales may pay to or receive from the purchasers of such
shares commissions computed as described above.  To the extent required under
the Securities Act, a supplemental prospectus will be filed, disclosing:

     .  the name of any such broker-dealers;

     .  the number of shares involved;

     .  the price at which such shares are to be sold;

     .  the commissions paid or discounts or concessions allowed to such broker-
        dealers, where applicable;

     .  that such broker-dealers did not conduct any investigation to verify the
        information set out or incorporated by reference in this prospectus, as
        supplemented; and

     .  other facts material to the transaction.

     Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the resale of shares may not simultaneously
engage in market making activities with respect to our common stock for a period
of two business days prior to the commencement of such distribution.  In
addition, the selling stockholders will be subject to applicable provisions of
the Exchange Act, and the rules and regulations thereunder, including, without
limitation, Regulation M, which provisions may limit the timing of purchases and
sales of shares of Pilot's common stock by the selling stockholders.

     The selling stockholders will pay all commissions, transfer taxes, and
certain other expenses associated with the sale of securities by them.  The
shares offered hereby are being registered pursuant to our contractual
obligations, and we paid the expenses of the preparation of this prospectus; we
will also have to bear the expense of maintaining the effectiveness of the
registration statement of which this prospectus forms a part.

                         DESCRIPTION OF CAPITAL STOCK

     As of the date of this prospectus, the authorized capital stock of Pilot
consists of 40,000,000 shares of common stock, $0.001 par value, and 2,000,000
shares of preferred stock, $0.001 par value.

Common Stock

     As of July 1, 2000, there were 15,080,927 shares of common stock
outstanding held of record by approximately 99 registered stockholders.
However, we believe, that many beneficial holders of our common stock have
registered their shares in nominee or street name.  The holders of common stock
are entitled to one vote per share on all matters to be voted on by
stockholders, except that holders may cumulate their votes in the election of
directors.  Subject to preferences that may be applicable to any outstanding
preferred stock, common stockholders are entitled to receive ratably such
dividends as may be declared by the Board of Directors in its discretion from
funds legally available therefor.  In the event of a liquidation, dissolution,
or winding up of Pilot, common stockholders are entitled to share ratably in all
assets remaining after payment of liabilities and the liquidation preference of
any outstanding preferred stock.  Common stockholders have no preemptive rights
and have no rights to convert their common stock into any other securities.  The
outstanding shares of common stock are fully paid and non-assessable.

Preferred Stock

     The Board of Directors has the authority to issue up to 2,000,000 shares of
preferred stock in one or more series and to fix the rights, preferences,
privileges and restrictions thereof, including dividend rights, conversion
rights, voting rights, terms of redemption, liquidation preferences and the
number of shares constituting any series or the designation of such series,
without any further vote or action by the stockholders.  The issuance of
preferred stock may have the effect of delaying, deferring or preventing a
change in control of Pilot or making removal of management more difficult
without further action by the shareholders and could adversely affect the rights
and powers, including voting rights, of the holders of common stock.  These
provision could also affect the market price of our common stock.

     15,000 shares of Preferred Stock have been designated as Series A
convertible preferred stock.  All of the shares of Series A convertible
preferred stock have been issued and sold to Marshall Capital pursuant to the
securities purchase agreement.

     The terms of the Series A convertible preferred stock are summarized below.

     Conversion: Each share of Series A convertible preferred stock has a stated
value of $1,000 and is convertible, at the election of the holder, into that
number of shares of our common stock as is equal to $1,000 plus the amount of
any unpaid dividends that have accrued on such preferred shares, plus any unpaid
premium, divided by the conversion price. The conversion price is equal to the
lower of:

     .    $18.266, which is equal to 25% above the average closing bid of our
          common stock for the five day trading period immediately preceding
          June 28, 2000, the issue date of the Series A convertible preferred
          stock to Marshall Capital (the "fixed conversion price"), and

     .    an amount equal to 101% of the average of the three lowest closing bid
          prices for the 10 trading days immediately preceding the day of
          conversion (the "market conversion price").

                                      12
<PAGE>

     The following limitations apply to this conversion price:

     .    during the 90 day period beginning on June 28, 2000, the conversion
          may only be effected at the fixed conversion price, and

     .    if on any day, the average closing price of the common stock for the
          preceding five days is greater than 200% of the fixed conversion
          price, and the registration statement is effective on this day and the
          five days immediately preceding that date, thereafter the conversion
          may only be effected at the fixed conversion price.

     In addition, the aggregate number of shares of common stock issuable upon
conversion of the Series A convertible preferred stock and any other shares of
common stock aggregated with such shares under the Nasdaq Marketplace Rules
generally may not exceed 3,014,199, which is equal to 19.99% of the number of
shares of our common stock outstanding on June 28, 2000.  However, we may issue
more than 3,014,199 shares in connection with the conversion of the Series A
convertible preferred stock at its maturity in June 2002 provided that our
stockholders have approved the issuance prior to that date.

     The following are examples of how the conversion price works, assuming that
neither of the two limitations on the conversion price apply, and that there are
no premiums or dividends:

          Example 1:  If the average of the three lowest closing bid prices for
                      the 10 day trading period immediately prior to the
                      conversion date is $10 then each share of Series A
                      convertible preferred stock would convert into
                      approximately 99 shares of our common stock.

          Example 2:  If the average of the three lowest closing bid prices for
                      the 10 day trading period immediately prior to conversion
                      is $15, then each share of Series A convertible preferred
                      stock would convert into approximately 66 shares of our
                      common stock.

          Example 3:  If the average of the three lowest closing bid prices for
                      the 10 day trading period immediately prior to the
                      conversion date is $30, then each share of Series A
                      convertible preferred stock would convert into
                      approximately 55 shares of our common stock. In this
                      example the conversion price is equal to the fixed
                      conversion price, or $18.266, since that amount is lower
                      than the $30 average market price.

     The above averages will be adjusted and recalculated based on each separate
conversion date.

     The significance of having conversion factors based upon the average
closing bid price of our common stock is that it allows the holder to receive a
greater number of shares of common stock if our common stock price declines.
The significance of having the fixed conversion price set at 25% above the
average closing bid price as of June 28, 2000 is that the holder will receive at
least a minimum number of shares upon conversion if our stock price rises above
that price.

     The conversion price of the Series A convertible preferred stock is subject
to modification and adjustment. For example, the conversion price will be
adjusted in connection with stock splits, distributions and certain issuances of
securities below the then existing conversion price.

     The Series A convertible preferred stock has a liquidation preference equal
to the stated value, plus all unpaid dividends and premiums accrued.

                                      13
<PAGE>

     The Series A convertible preferred stock may be redeemed or converted into
common stock at our election on June 28, 2002 (the "maturity date").  On the
maturity date, we will have the option of redeeming the outstanding Series A
convertible preferred shares at the stated value, provided that the conditions
below are satisfied, the outstanding Series A convertible preferred shares may
be converted into a number of shares of common stock equal to the stated value
of the shares divided by the average closing bid price of the common stock for
the five-day trading period immediately preceding the maturity date.

     We do not have the power to convert the Series A convertible preferred
stock into common stock unless all of the following conditions are satisfied:

     .    we must provide written notice of our intention to redeem the shares
          at least 10 business days prior to the maturity date;

     .    our common stock must be actively traded on the New York Stock
          Exchange, the American Stock Exchange, or the Nasdaq National Market;

     .    a redemption event (as described below) shall not have occurred and be
          continuing;

     .    the conversion to common stock must not result in Marshall Capital and
          its affiliates beneficially owning more than 3,014,199 shares of our
          common stock unless our stockholders have approved the issuance of a
          greater amount prior to the maturity date; and

     .    the registration statement of which this prospectus forms a part is
          effective and available for the resale of the number of securities
          required by the registration rights agreement (as explained in the
          Selling Stockholder section above).

     Redemption:  Under certain circumstances, the Series A convertible
preferred stock is subject to redemption at a premium three days following a
written request by the holders of the Series A convertible preferred stock, who
can request redemption upon the occurrence of events described in the
Certificate of Designations, Rights and Preferences of the Series A convertible
preferred stock, including the following:

     .    if we do not timely issue common stock following conversion by a
          holder of Series A convertible preferred stock;

     .    if we materially breach, and fail to timely cure, any covenant,
          material term or condition of the securities purchase agreement or
          other transaction document;

     .    if any covenant, material term, or condition of the securities
          purchase agreement or other transaction document is materially
          misleading as of the date of such representation;

     .    if we undergo a change in control;

     .    if we fail to maintain the listing of our common stock on the American
          Stock Exchange, the New York Stock Exchange, or the Nasdaq National
          Market; or

     .    the registration statement of which this prospectus forms a part is
          not declared effective within 180 days of the issue date of the
          shares.

     The dollar amount of the redemption is equal to the greater of:

                                      14
<PAGE>

     .    the value of the shares of Series A convertible preferred stock
          requested to be redeemed; or

     .    the value of the Series A convertible preferred stock requested to be
          redeemed divided by the market conversion price as described above in
          effect on the date of redemption and multiplying the resulting
          quotient by the average closing bid price for the common stock for the
          5 days immediately preceding the redemption date.

     Dividend Rights:  Holders of Series A convertible preferred stock are
entitled to cumulative dividends at an annual rate of 3% of the purchase price
of the Series A convertible preferred stock.  The dividends cumulate and are
payable quarterly.  The amount of each dividend is payable in cash, or, at our
election, in shares of our common stock.  In the event the dividends are paid in
common stock, the number of shares to be delivered will be determined by
dividing the dollar amount of the dividends that have accrued by the market
conversion price as defined above in effect on the date the dividend is due.  In
order for us to pay dividends in common stock, the following conditions must be
met:

     .    a redemption event as described above cannot have occurred and be
          continuing;

     .    the registration statement must be declared effective and must cover

Item 15.  Indemnification of Officers and Directors.

     Our Certificate of Incorporation limits, to the maximum extent permitted by
Delaware law, the personal liability of directors for monetary damages for
breach of their fiduciary duties as a director.  Our Bylaws provide that we will
indemnify our officers and directors and may indemnify our employees and other
agents to the fullest extent permitted by Delaware law.  We have entered into
indemnification agreements with our officers and directors containing provisions
which are in some respects broader than the specific indemnification provisions
contained in the Delaware General Corporation Law.  The indemnification
agreements require us, among other things to indemnify such officers and
directors against certain liabilities that may arise by reason of their status
or service as directors or officers (other than liabilities arising from willful
misconduct of a culpable nature), to advance their expenses incurred as a result
of any proceeding against them as to which they could be indemnified, and to
obtain directors' and officers' insurance, if available on reasonable terms.  We
believe that these agreements are necessary to attract and retain qualified
persons as directors and officers.

     Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify a director, officer, employee or agent made a party to
an action by reason of that fact that he or she was a director, officer,
employee or agent of the corporation or was serving at the request of the
corporation against expenses actually and reasonably incurred by him or her in
connection with such action if he or she acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interests of
the corporation and with respect to any criminal action, had no reasonable cause
to believe his or her conduct was unlawful.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Registrant
pursuant to the foregoing provisions, the Registrant has been informed 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.

Item 17.  Undertakings.

     A.   The undersigned Pilot Network Services Inc. hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement;

               (i)   To include any prospectus required by section 10(a)(3) of
          the Securities Act of 1933;

               (ii)  To reflect in the prospectus any facts or events arising
          after the effective date of the Registration Statement (or the most
          recent post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the Registration Statement;

               (iii) To include any material information with respect to the
          plan of distribution not previously disclosed in the Registration
          Statement or any material change to such information in the
          Registration Statement;

     Provided, however, that paragraphs (i) and (ii) shall not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by Pilot Network Services,
Inc. pursuant to section 13 or section 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the Registration Statement.

          (2)  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.

                                      II-2
<PAGE>

          (3)  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.

     B.   That, for purposes of determining any liability under the Securities
Act of 1933, each filing of Pilot Network Services Inc.'s annual report pursuant
to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offering therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     C.   Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of Pilot Network Services Inc. pursuant to the provisions described
under Item 14 above, or otherwise, Pilot Network Services Inc. has been advised
that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by Pilot Network Services Inc. of
expenses incurred or paid by a director, officer or controlling person of Pilot
Network Services Inc. in the successful defense of any action, suit or
proceeding) is asserted against Pilot Network Services Inc. by such director,
officer or controlling person in connection with the securities being
registered, Pilot Network Services Inc. will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

     The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X is not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.
