    THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M. NEW YORK CITY TIME ON
           , 1998 UNLESS EXTENDED.
 
    FirstWorld Communications, Inc., a Delaware corporation ("FirstWorld" or the
"Company"), is hereby offering (the "Exchange Offer"), upon the terms and
subject to the conditions set forth in this Prospectus (as the same may be
amended or supplemented from time to time, the "Prospectus") and the
accompanying Letter of Transmittal (the "Letter of Transmittal"), to exchange
$1,000 in principal amount at maturity of its new 13% Senior Discount Notes due
2008 (the "Exchange Notes"), which exchange has been registered under the
Securities Act of 1933, as amended (the "Securities Act"), pursuant to a
registration statement of which this Prospectus is a part (the "Registration
Statement"), for each $1,000 in principal amount at maturity of its outstanding
13% Senior Discount Notes due 2008 (the "Private Notes"), of which $470,000,000
in aggregate principal amount at maturity was issued on April 13, 1998 (the
"Private Note Offering") and is outstanding as of the date hereof. The form and
terms of the Exchange Notes are the same as the form and terms of the Private
Notes except that (i) the exchange will have been registered under the
Securities Act, and, therefore, the Exchange Notes will not bear legends
restricting the transfer thereof and (ii) holders of the Exchange Notes will not
be entitled to certain rights of holders of the Private Notes under the
Registration Rights Agreement (as defined), which rights will terminate upon the
consummation of the Exchange Offer. The Exchange Notes will evidence the same
indebtedness as the Private Notes (which they replace) and will be entitled to
the benefits of an indenture dated as of April 13, 1998 governing the Private
Notes and the Exchange Notes (the "Indenture"). The Private Notes and the
Exchange Notes are sometimes referred to herein collectively as the "Notes." See
"The Exchange Offer" and "Description of Exchange Notes."
 
   
    The Exchange Notes will bear interest at the same rate and on the same terms
as the Private Notes. Consequently, the Exchange Notes will be issued at a
substantial discount to their principal amount at maturity. The Exchange Notes
will accrete in value from and including the date of issuance of the Private
Notes (April 13, 1998) until April 15, 2003 at which time they will have an
aggregate principal amount of $470.0 million. Thereafter, cash interest will
accrue on the Exchange Notes and will be payable semiannually in arrears on
April 15 and October 15, commencing October 15, 2003, at a rate of 13% per
annum.

THAT INVESTORS SHOULD CONSIDER IN CONNECTION WITH THE EXCHANGE OFFER AND AN
INVESTMENT IN THE EXCHANGE NOTES.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
     EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
        SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
             COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF
                THIS PROSPECTUS. ANY REPRESENTATION TO THE

    The Exchange Notes will be senior obligations of the Company, will rank PARI
PASSU in right of payment with all existing and future senior Indebtedness of
the Company and will rank senior in right of payment to any future Subordinated
Indebtedness of the Company, but will be effectively subordinated to any secured
Indebtedness of the Company and future Indebtedness and other liabilities
(including Subordinated Indebtedness and trade payables) of the Company's
Subsidiaries. The Indenture will permit the incurrence of substantial additional
Indebtedness, including secured Indebtedness, by the Company and its
Subsidiaries, subject to certain restrictions. See "Risk Factors--Effective
Subordination of Notes; Holding Company Structure." As of June 30, 1998, the
Company had no Subordinated Indebtedness and $7.1 million in outstanding
Indebtedness that ranks PARI PASSU with the Notes.
    
 
    No cash interest will accrue or be payable in respect of the Exchange Notes
prior to April 15, 2003. Thereafter, interest will accrue at the rate of 13% per
annum, payable semiannually in arrears on each April 15 and October 15,
commencing on April 15, 2003. The Private Notes accepted for exchange will
continue to accrete in principal amount at the rate of 13% per annum to, but
excluding, the issuance date of the Exchange Notes and will cease to accrete in
principal amount upon cancellation of the Private Notes and issuance of the
Exchange Notes. Any Private Notes not tendered or accepted for exchange will
continue to accrete in principal amount at the rate of 13% per annum in
accordance with its terms. The Accreted Value of the Exchange Notes will equal
the Accreted Value of the Private Notes accepted for exchange immediately prior
to issuance of the Exchange Notes.
 
   
    The Notes will be redeemable at the option of the Company, in whole or in
part, on or after April 15, 2003, at the redemption prices set forth herein,
plus accrued and unpaid interest thereon, if any, to the date of redemption. If
less than all of the Exchange Notes are to be redeemed at any time, selection of
Exchange Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Exchange Notes are listed or, if the Exchange Notes are not so listed, on a pro
rata basis, by lot or by such method as the Trustee shall deem fair and
appropriate; PROVIDED that no Exchange Notes of $1,000 or less shall be redeemed
in part. Upon the occurrence of a Change of Control (as defined), holders of the
Exchange Notes will have the right to require the Company to repurchase their
Exchange Notes, in whole or in part, at a purchase price equal to 101% of the
aggregate principal amount thereof, plus accrued and unpaid interest and Special
Interest (as defined), if any, thereon to the date of repurchase. The Company's
ability to pay cash to the holders of Exchange Notes upon a repurchase may be
limited by the Company's then existing financial resources. See "Description of
Exchange Notes--Repurchase at the Option of Holders--Change of Control."
    
 
    The Company will accept for exchange any and all validly tendered Private
Notes not withdrawn prior to 5:00 p.m. New York City time, on            , 1998,
unless the Exchange Offer is extended by the Company in its sole discretion (the
"Expiration Date"). Tenders of Private Notes may be withdrawn at any time prior
to the Expiration Date. Private Notes may be tendered only in integral multiples
of $1,000. The Exchange Offer is not conditioned upon any minimum amount of
Private Notes being tendered for exchange. However, the Exchange Offer is
subject to certain customary conditions. See "The Exchange Offer--Conditions."
In the event the Company terminates the Exchange Offer and does not accept for
exchange any Private Notes, the Company will promptly return the Private Notes
to the holders thereof. The Company will not receive any proceeds from the
Exchange Offer. See "The Exchange Offer."
 
    Based on an interpretation by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties (See e.g. EXXON CAPITAL HOLDINGS CORP., SEC No-Action Letter (available
April 13, 1989) and MORGAN STANLEY & CO. INC., SEC No-Action Letter (available
June 5, 1991) collectively, the "No-Action Letters"), the Company believes that
the Exchange Notes issued

pursuant to the Exchange Offer in exchange for Private Notes may be offered for
resale, resold and otherwise transferred by a holder thereof (other than (i) a
broker-dealer who purchases such Exchange Notes directly from the Company to
resell pursuant to Rule 144A or any other available exemption under the
Securities Act or (ii) a person that is an affiliate of the Company within the
meaning of Rule 405 under the Securities Act), without compliance with the
registration and prospectus delivery provisions of the Securities Act; PROVIDED
that the holder is acquiring the Exchange Notes in the ordinary course of its
business and is not participating, and had no arrangement or understanding with
any person to participate, in the distribution of the Exchange Notes. Holders
who tender their Private Notes in the Exchange Offer with the intention of
participating in a distribution of the Exchange Notes will not be able to rely
on the No-Action Letters or similar no-action letters. Holders of Private Notes
wishing to accept the Exchange Offer must represent to the Company, as required
by the Registration Rights Agreement, that such conditions have been met. Each
broker-dealer that receives Exchange Notes for its own account in exchange for
Private Notes, where such Private Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such Exchange
Notes. The Company believes that none of the registered holders of the Private
Notes is an affiliate (as such term is defined in Rule 405 under the Securities
Act) of the Company.
 
    Prior to the Exchange Offer, there has been no public market for the Notes.
The Company does not intend to list the Exchange Notes on any securities
exchange, but the Private Notes are eligible for trading in the National
Association of Securities Dealers, Inc.'s Private Offerings, Resales and Trading
through Automatic Linkages (PORTAL) market. There can be no assurance that an
active market for the Notes will develop. To the extent that a market for the
Notes does develop, the market value of the Notes will depend on market
conditions (such as yields on alternative investments), general economic
conditions, the Company's financial condition and certain other factors. Such
conditions might cause the Notes, to the extent that they are traded, to trade
at a significant discount from face value. See "Risk Factors--Absence of Public
Market; Restrictions on Transfer."
 
    Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of

    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND CONSOLIDATED FINANCIAL STATEMENTS OF THE COMPANY, THE NOTES
THERETO AND THE OTHER FINANCIAL DATA CONTAINED ELSEWHERE IN THIS PROSPECTUS.
PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE FACTORS SET FORTH HEREIN
UNDER THE CAPTION "RISK FACTORS" AND ARE URGED TO READ THIS PROSPECTUS IN ITS

                                  THE COMPANY
 
    FirstWorld Communications, Inc. ("FirstWorld" or the "Company") is a
facilities-based integrated communications provider ("ICP") which is deploying
networks to provide telecommunications solutions to business customers in
clustered, demographically attractive second tier markets. The Company offers
"one-stop shopping" for a broad array of telecommunications services, including
local and long distance telephone service, high speed Internet access, data
connectivity, local area network ("LAN") connectivity, web hosting, video
communications and system integration services. Within its target markets, the
Company has segmented the potential business customer base and tailors its
service offerings, sales and marketing approach and network development to
provide service in a cost-effective manner to each segment. The Company believes
its regional approach allows it to best leverage its network facilities, sales
force, customer support staff and brand identity. The Company's first network
clusters will serve second tier markets surrounding metropolitan Los Angeles,
including Orange County and the San Gabriel Valley and South Bay areas of Los
Angeles County. The Company intends to selectively expand its reach into other
regional markets, both within and outside of California.
 
   
    The Company began network operations in July 1997 and began providing
services to commercial customers in November 1997. As of July 31, 1998, the
Company had approximately 100 commercial customers under contract. The City of
Anaheim, the Company's most significant customer, relies on the Company to
supply local dialtone, long distance, dedicated facilities and Internet service
to substantially all of its municipal facilities.
    
 
    FirstWorld has designed and implemented an advanced and reliable fiber-based
network. Central to the Company's network design is its state-of-the-art
integrated voice and data central office service platform, which allows the
Company to integrate third-party systems and the Company's operational support
systems into a unified network. The Company believes its networks also are
capable of providing server-based applications, such as virtual LANs and
e-commerce, and will be compatible with voice over Internet technologies as such
technologies are refined in the industry. The Company has designed business
processes to simplify provisioning, billing, network management and customer
service and has incorporated operational support systems that implement such
processes into its networks. Among other things, the Company has designed its
systems to allow the Company to provide single-point-of-contact customer service
and to facilitate electronic exchanges of information with the incumbent local
exchange carrier ("ILEC") when possible.
 
    The Company employs a demand-driven approach to network construction. This
approach is intended to minimize deployment of capital not associated with
customer revenues and maximize flexibility to serve the higher margin data
market as demand for high speed data communication services grows. The Company
connects customers to its networks through direct fiber connections, digital
subscriber line ("DSL") technology or unbundled network elements licensed from
the ILEC, depending on the most cost-effective connection that will support the
bundle of services provided to the customer. The Company generally requires
customers that are connected by fiber to sign long-term contracts to offset the
cost of capital deployed.
 
   
    The Company believes that the market segments within its target markets have
different customer buying patterns, are subject to different competitive factors
and can best be served by different sales and marketing initiatives. For prime
commercial customers (businesses with sophisticated communications needs), the
Company utilizes a consultative selling approach that involves a systematic
assessment of each
    
 
                                       1
<PAGE>
customer's telephony, Internet, data communications and video applications
needs. For basic commercial customers (businesses with primarily voice and
Internet needs), the Company uses direct mail, telemarketing and advertising and
offers standardized product bundles consisting of local and long distance
telephony and high speed Internet access. The Company also offers use of its
network capabilities on a wholesale basis to other local exchange carriers,
including competitive local exchange carriers ("CLECs"), interexchange carriers
("IXCs"), Internet service providers ("ISPs") and other communications
providers.
 
    The Company uses strategic relationships with municipalities, property
developers, service providers and others that provide the Company with brand
identity, physical assets, new products or technologies, joint marketing
synergies or other support. The Company believes its existing relationships with
the City of Anaheim, The Irvine Company and Enron provide the Company with
significant advantages in marketing and network deployment.
 
   
    The Company's largest stockholders are entities controlled by Donald L.
Sturm, former Vice Chairman of Peter Kiewit Sons' Inc., the founder of MFS
Communications Company, Inc. ("MFS Communications"), and Enron Capital & Trade
Resources Corp. ("Enron"), a subsidiary of Enron Corp., one of the world's
leading integrated natural gas and electricity companies. To date, these
stockholders have provided $55 million of the $67 million in equity capital
received by the Company. The Company and Enron have an informal collaborative
relationship to jointly market telecommunications and utility services which the
Company believes can provide it with access to new markets, sales synergies and
product development opportunities.
    
 
   
    The Company has assembled a management team with extensive experience in
telecommunications network engineering and operations, customer care, sales and
marketing, project development and finance. Donald L. Sturm, the Company's
Chairman, President and Chief Executive Officer, has extensive experience in the
telecommunications industry. Many of the other members of the management team
have prior telecommunications industry experience, including prior positions at
Pacific Bell, WorldCom, Inc. ("WorldCom"), Sprint Communications Company, L.P.
("Sprint") and other major telecommunications providers. The Company believes
the skill and experience of its management team will continue to provide
significant benefits as the Company continues to enhance and expand its
networks.
    
 
   
    The Company's principal executive offices are located at 9333 Genesee
Avenue, Suite 200, San Diego, California 92121, and its phone number is (619)
552-8010. In January 1998, the Company changed its name from SpectraNet
International to FirstWorld Communications, Inc. In June 1998, the Company
changed its state of incorporation from California to Delaware.

                                        Based on an interpretation by the staff of the Commission set

ACCRETION OF THE EXCHANGE NOTES AND
  THE PRIVATE NOTES...................  No cash interest will accrue or be payable in respect of the
                                        Exchange Notes prior to April 15, 2003. Thereafter, interest
                                        will accrue at the rate of 13% per annum, payable semiannually
                                        in arrears on each April 15 and October 15, commencing on
                                        October 15, 2003. The Private Notes accepted for exchange will
                                        continue to accrete in principal amount at the rate of 13% per
                                        annum to, but excluding, the issuance date of the Exchange
                                        Notes and will cease to accrete in principal amount upon

                                        13% per annum in accordance with its terms. The Accreted Value
                                        of the Exchange Notes will equal the Accreted Value of the
                                        Private Notes accepted for exchange immediately prior to
                                        issuance of the Exchange Notes.

                                        selling securityholder information required by Item 507 or
                                        Item 508, as applicable, of Regulation S-K of the Commission
                                        and (v) such holder is not an "affiliate," as defined in Rule
                                        405 under the Securities Act, of the Company. If the holder is
                                        a broker-dealer that will receive Exchange Notes for its own
                                        account in exchange for Private Notes that were acquired as a

                                        activities, such holder will be required to acknowledge in the
                                        Letter of Transmittal that such holder will deliver a
                                        prospectus in connection with any resale of such Exchange
                                        Notes; however, by so acknowledging and by delivering a
                                        prospectus, such holder will not be deemed to admit that it is
                                        an "underwriter" within the meaning of the Securities Act. See
                                        "The Exchange Offer--Procedures for Tendering."
 
SPECIAL PROCEDURES FOR BENEFICIAL
  OWNERS..............................  Any beneficial owner whose Private Notes are registered in the
                                        name of a broker, dealer, commercial bank, trust company or
                                        other nominee and who wishes to tender such Private Notes in
                                        the Exchange Offer should contact such registered holder
                                        promptly and instruct such registered holder to tender on such
                                        beneficial owner's behalf. If such beneficial owner wishes to
                                        tender on such owner's own behalf, such owner must, prior to
                                        completing and executing the Letter of Transmittal and
                                        delivering such owner's Private Notes, either make appropriate
                                        arrangements to register ownership of the Private Notes in
                                        such owner's name or obtain a properly completed bond power
                                        from the registered holder. The transfer of registered
                                        ownership may take considerable time and may not be able to be
                                        completed prior to the Expiration Date. See "The Exchange
                                        Offer--Procedures for Tendering."
 
GUARANTEED DELIVERY PROCEDURES........  Holders of Private Notes who wish to tender their Private
                                        Notes and whose Private Notes are not immediately available or
                                        who cannot deliver their Private Notes, the Letter of
                                        Transmittal or any other documentation required by the Letter
                                        of Transmittal to the Exchange Agent prior to the Expiration
                                        Date must tender their Private Notes according to the
                                        guaranteed delivery procedures set forth under "The Exchange
                                        Offer--Guaranteed Delivery Procedures."
 
ACCEPTANCE OF THE PRIVATE NOTES AND
  DELIVERY OF THE EXCHANGE NOTES......  Subject to the satisfaction or waiver of the conditions to the
                                        Exchange Offer, the Company will accept for exchange any and
                                        all Private Notes that are properly tendered in the Exchange
                                        Offer prior to the Expiration Date. The Exchange Notes issued
                                        pursuant to the Exchange Offer will be delivered on the
                                        earliest practicable date following the Expiration Date. See
                                        "The Exchange Offer--Terms of the Exchange Offer."
 
WITHDRAWAL RIGHTS.....................  Tenders of Private Notes may be withdrawn at any time prior to
                                        the Expiration Date. See "The Exchange Offer--Withdrawal of
                                        Tenders."

EXCHANGE AGENT........................  The Bank of New York is serving as the Exchange Agent in

                               THE EXCHANGE NOTES
 
    The Exchange Offer applies to up to $470,000,000 in aggregate principal
amount at maturity of the Private Notes. The form and terms of the Exchange
Notes are the same as the form and terms of the Private Notes except that (i)
the exchange will have been registered under the Securities Act and, therefore,
the Exchange Notes will not bear legends restricting the transfer thereof and
(ii) holders of the Exchange Notes will not be entitled to certain rights of
holders of the Private Notes under the Registration Rights Agreement, which
rights will terminate upon consummation of the Exchange Offer. The Exchange
Notes will evidence the same debt as the Private Notes (which they replace) and
will be issued under, and be entitled to the benefits of, the Indenture. For
further information and for definitions of certain capitalized terms used below,
see "Description of Exchange Notes."

SECURITIES OFFERED........................  $470,000,000 in aggregate principal amount at maturity of 13% Senior
                                            Discount Notes due 2008.
 
MATURITY..................................  April 15, 2008.
 
INTEREST..................................  The Exchange Notes will be issued at a substantial discount to their
                                            principal amount at maturity, and will accrete in value through April
                                            15, 2003 (the "Full Accretion Date") at a rate of 13% per annum,
                                            compounded semi-annually. Cash interest will neither accrue nor be
                                            payable on the Exchange Notes prior to the Full Accretion Date.
                                            Thereafter, the Exchange Notes will bear interest at the rate of 13%
                                            per annum, payable in cash semi-annually in arrears on April 15 and
                                            October 15 commencing October 15, 2003.
 
ORIGINAL ISSUE DISCOUNT...................  For United States federal income tax purposes, an Exchange Note
                                            received pursuant to the Exchange Offer will be treated as a
                                            continuation of the Private Note in the hands of a holder. As a
                                            result, such holder will have the same adjusted tax basis, holding
                                            period and original issue discount in the Exchange Note as it had in
                                            the Private Note immediately before the exchange. See "Certain United
                                            States Federal Income Tax Considerations."
 
RANKING...................................  The Exchange Notes will be senior obligations of the Company, will
                                            rank PARI PASSU in right of payment with all existing and future
                                            senior Indebtedness of the Company and will rank senior in right of
                                            payment to any future Subordinated Indebtedness of the Company, but
                                            will be effectively subordinated to any secured Indebtedness of the
                                            Company and future Indebtedness and other liabilities (including
                                            Subordinated Indebtedness and trade payables) of the Company's
                                            Subsidiaries. The Indenture will permit the incurrence of substantial
                                            additional Indebtedness, including secured Indebtedness, by the
                                            Company and its Subsidiaries, subject to certain restrictions. See

                                            In addition, at any time prior to or on April 15, 2001, the Company
                                            may redeem up to 35% of the Accreted Value of the Notes at a
                                            redemption price of 113% of the Accreted Value thereof at the time of
                                            redemption, with the net cash proceeds of one or more Public Equity
                                            Offerings (as defined) or the sale of Capital Stock (as defined) to

                                            of such redemption.
 
CHANGE OF CONTROL.........................  In the event of a Change of Control, the holders of the Exchange
                                            Notes will have the right to require the Company to purchase the
                                            Exchange Notes at a price equal to 101% of the aggregate principal

                                            unpaid interest to the date of purchase. There can be no assurance
                                            that the Company will have the financial resources necessary to
                                            repurchase the Exchange Notes upon a Change of Control.

    The summary consolidated financial data presented below for the period from
September 1, 1993 (inception) to September 30, 1993, for the years ended
September 30, 1994, 1995, 1996 and 1997, for the period from September 1, 1993
(inception) to September 30, 1997, and as of September 30, 1997 have been
derived from the audited consolidated financial statements of the Company. The
summary consolidated financial data presented below as of June 30, 1998 and for
the nine month periods ended June 30, 1997 and 1998 and the period from
September 1, 1993 (inception) to June 30, 1998 have been derived from the
unaudited consolidated financial statements of the Company. In the opinion of
management, the unaudited financial statements have been prepared on the same
basis as the audited financial statements and include all adjustments, which
consist only of normal recurring adjustments, necessary for a fair presentation
of the financial position and the results of operations for these periods. These
financial statements have been prepared in accordance with accounting principles
generally accepted in the United States which may differ in certain aspects from
accounting principles generally accepted in certain of the jurisdictions in
which the Exchange Notes are being offered. Operating results for the nine month
period ended June 30, 1998 are not necessarily indicative of the results that

(1) EBITDA represents earnings before interest, income taxes, depreciation and
    amortization. EBITDA is not a measurement of financial performance under
    generally accepted accounting principles, is not intended to represent cash
    flow from operations, and should not be considered as an alternative to net
    loss as an indicator of the Company's operating performance or to cash flows
    as a measure of liquidity. The Company believes that EBITDA is widely used
    by analysts, investors and other interested parties in the
    telecommunications industry. The Company's computation of EBITDA may not be
    comparable to similarly titled measures for other companies.
    
 
   
(2) For purposes of calculating the ratio of earnings to fixed charges, earnings
    is defined as net loss plus fixed charges (other than capitalized interest).
    Fixed charges consist of interest and amortization of debt discount and debt
    issuance costs, whether expensed or capitalized, and that portion of rental
    expense deemed to represent interest (estimated to be one-third of such
    expense). For the periods presented, earnings were insufficient to cover
    fixed charges by the amounts disclosed.

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS,
PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER ALL OF THE INFORMATION CONTAINED
IN THIS PROSPECTUS AND, IN PARTICULAR, SHOULD EVALUATE THE FOLLOWING RISK
FACTORS. CERTAIN STATEMENTS IN THIS PROSPECTUS THAT ARE NOT HISTORICAL FACT
CONSTITUTE "FORWARD-LOOKING STATEMENTS." SUCH FORWARD-LOOKING STATEMENTS INVOLVE
KNOWN AND UNKNOWN RISKS, UNCERTAINTIES AND OTHER FACTORS THAT MAY CAUSE THE
ACTUAL RESULTS OF THE COMPANY TO BE MATERIALLY DIFFERENT FROM RESULTS EXPRESSED
OR IMPLIED BY SUCH FORWARD-LOOKING STATEMENTS. SUCH RISKS, UNCERTAINTIES AND
OTHER FACTORS INCLUDE, BUT ARE NOT LIMITED TO, THE FOLLOWING FACTORS.
 
FAILURE TO EXCHANGE PRIVATE NOTES
 
    The Exchange Notes will be issued in exchange for Private Notes only after
timely receipt by the Exchange Agent of such Private Notes, a properly completed
and duly executed Letter of Transmittal and all other required documentation.
Therefore, holders of Private Notes desiring to tender such Private Notes in
exchange for Exchange Notes should allow sufficient time to ensure timely
delivery. Neither the Exchange Agent nor the Company is under any duty to give
notification of defects or irregularities with respect to tenders of Private
Notes for exchange. Private Notes that are not tendered or are tendered but not
accepted will, following consummation of the Exchange Offer, continue to be
subject to the existing restrictions upon transfer thereof. In addition, any
holder of Private Notes who tenders in the Exchange Offer for the purpose of
participating in a distribution of the Exchange Notes will be required to comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale transaction. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Private Notes, where such
Private Notes were acquired by such broker-dealer as a result of market-making
activities or any other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. To
the extent that Private Notes are tendered and accepted in the Exchange Offer,
the trading market for untendered and tendered but unaccepted Private Notes
could be adversely affected due to the limited amount, or "float," of the
Private Notes that are expected to remain outstanding following the Exchange
Offer. Generally, a lower "float" of a security could result in less demand to
purchase such security and could, therefore, result in lower prices for such
security. For the same reason, to the extent that a large amount of Private
Notes are not tendered or are tendered and not accepted in the Exchange Offer,
the trading market for the Exchange Notes could be adversely affected. See "Plan
of Distribution" and "The Exchange Offer."
 
LIMITED HISTORY OF OPERATIONS; NEGATIVE CASH FLOW AND OPERATING LOSSES
 
   
    The Company was incorporated in July 1992, commenced operations in September
1993 and commenced commercial operation of its current network business in
November 1997. The Company has provided services to customers for slightly more
than one year, and as of July 31, 1998 had approximately 100 commercial
customers under contract. The Company has generated substantial operating losses
and negative cash flow from operating activities since its inception and expects
that operating and net losses and negative operating cash flow will continue for
at least the next several years and will increase significantly as the Company
implements its growth strategy of expanding into other cities. To date, the
Company has focused primarily on the development of its product line, the
development and construction of its networks, the hiring of management and other
key personnel, the raising of capital, the acquisition of equipment, the
implementation of its sales and marketing strategy and the development of
operating systems. Accordingly, potential investors have limited operating and
financial data about the Company upon which to base an evaluation of the
Company's performance and an investment in the Exchange Notes offered hereby.
The Company has a very limited operating history upon which to base estimates of
the number of customers, the reliability of its network or the amount of
revenues the Company's current and planned operations will generate. Given the
Company's limited operating history, there can be no assurance that it will be
able to achieve its goals, generate sufficient positive cash flows to make
principal
    
 
                                       10
<PAGE>
and interest payments on its indebtedness, including the Notes, or compete
successfully in the telecommunications industry.
 
   
    The Company's prospects must be considered in light of the risks, expenses
and difficulties frequently encountered by companies in new and rapidly evolving
markets. To address these risks, the Company must, among other things, attract
and retain customers, increase awareness of the Company's services, respond to
competitive developments, continue to attract, retain and motivate qualified
persons and continue to upgrade its technologies and commercialize its network
services incorporating such technologies. There can be no assurance that the
Company will be successful in addressing such risks and the failure to do so
could have a material adverse effect on the Company's business, financial
condition and results of operations and the Company's ability to make principal
and interest payments on its indebtedness, including the Notes. The Company's
business strategy is unproved and, to be successful, the Company must, among
other things, develop and market services that are widely accepted by customers
at prices that will yield a profit. There can be no assurance that the Company
and its services will achieve broad customer or commercial acceptance when
compared to alternative telecommunications services. Given the dynamic nature of
the marketplace for telecommunications services, the prices the Company charges
for some or all of its services may from time to time be higher than those
charged by providers for some competing services, although the Company is not
aware of any specific type of service that it currently prices higher than its
competitors. Additionally, prices for telecommunications services have fallen
historically, and prices in the industry in general, and for the services the
Company offers and plans to offer in particular, are expected to continue to
fall. Accordingly, it is difficult to predict whether the Company's pricing
model will prove to be viable, whether demand for the Company's services will
materialize at the prices it expects to charge or whether current or future
pricing levels will be sustainable. The failure to achieve or sustain projected
pricing levels or to achieve or sustain broad market acceptance could result in
a material adverse effect on the Company's business, financial condition and
results of operations and the Company's ability to make principal and interest
payments on its indebtedness, including the Notes. Because of the foregoing
factors, among others, the Company may not be able to forecast its revenues or
the rate at which it will add new customers or end-users with any degree of
accuracy. The Company's annual and quarterly operating results may fluctuate
significantly in the future as a result of numerous factors, many of which are
outside the Company's control. Factors that may affect the Company's operating
results include the amount and timing of capital expenditures and other costs
relating to the expansion of the Company's network, the introduction of new
services by the Company or its competitors, price competition by competitors,
technical difficulties or network downtime, general economic conditions and
economic conditions specific to the Company's industry.
    
 
   
    The development of the Company's business and the deployment of its services
and systems will require significant additional capital expenditures, a
substantial portion of which will need to be incurred before the realization of
significant revenues. Together with associated start-up operating expenses,
these capital expenditures will result in substantial negative cash flow until
an adequate revenue-generating customer base is established. The Company has
incurred net losses in each quarter since it commenced operations in September
1993, with cumulative losses totaling approximately $39.0 million through June
30, 1998. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations." The Company expects to continue to generate significant
operating and net losses for at least the next several years. There can be no
assurance that the Company will achieve or sustain profitability or generate
sufficient positive cash flow to meet its working capital requirements or make
principal and interest payments on its indebtedness, including the Notes. See
"--Substantial Leverage; Ability to Service Indebtedness."
    
 
SUBSTANTIAL LEVERAGE; ABILITY TO SERVICE INDEBTEDNESS
 
   
    The Company will be highly leveraged following the Exchange Offer. As of
June 30, 1998, the Company had approximately $243.2 million of outstanding
indebtedness, the Company's total debt as a
    
 
                                       11
<PAGE>
   
percentage of capitalization was approximately 86% as of June 30, 1998 and the
Company had a deficiency of earnings to fixed charges of $19.4 million for the
nine months ended June 30, 1998. See "Capitalization," "Selected Consolidated
Financial Data" and "Certain Transactions." The Company's high degree of
leverage could have material and adverse consequences, including, but not
limited to, the following: (i) a substantial portion of the Company's sources of
capital and cash flow from operations must be dedicated to debt service
payments, thereby reducing the funds available to the Company for other
purposes; (ii) the Company's ability to obtain additional debt financing in the
future for working capital, capital expenditures, acquisitions, repayment of
indebtedness or other purposes may be impaired, whether as a result of the
covenants and other terms of its debt instruments or otherwise; (iii) the
Company will be substantially more leveraged than certain of its competitors,
which may place the Company at a competitive disadvantage; (iv) the Company's
high degree of leverage may limit its ability to expand capacity and otherwise
meet its growth objectives; and (v) the Company's high degree of leverage may
hinder its ability to adjust rapidly to changing market conditions and could
make it more vulnerable than its less leveraged competitors in the event of a
downturn in general economic conditions or its business. In addition, the
Indenture permits the incurrence of additional indebtedness under certain
conditions, and the Company expects that as it expands its networks beyond the
Orange County, San Gabriel Valley and South Bay areas, its capital requirements
will require it to secure additional financing, including additional
indebtedness. See "--Significant Capital Requirements."
    
 
    The Company's ability to make principal and interest payments on the Notes
will depend upon, among other things, its ability to complete the roll-out of
its networks on a timely and cost-effective basis, the market acceptance of, and
the utilization, pricing and consumer demand for its services, its future
operating performance and cash flow and its ability to obtain additional debt or
equity financing, which are themselves dependent upon a number of economic,
financial, competitive and regulatory conditions and other factors, many of
which the Company is unable to control. There can be no assurance that the
Company will have adequate sources of liquidity to make required payments of
principal and interest on its indebtedness (including the Notes), whether at or
prior to maturity, to finance anticipated capital expenditures and to fund
working capital requirements. If the Company does not have sufficient available
resources to repay its outstanding indebtedness when it becomes due and payable,
the Company may find it necessary to refinance such indebtedness, and there can
be no assurance that refinancing will be available or that it will be available
on favorable terms. Any failure by the Company to satisfy its obligations with
respect to its indebtedness at maturity or prior thereto would constitute a
default under such indebtedness and could cause a default under agreements
governing other indebtedness, if any, of the Company. Such defaults could result
in a default under the Indenture and could delay or preclude payment of interest
or principal on the Notes.
 
BUSINESS DEVELOPMENT AND EXPANSION RISKS; POSSIBLE INABILITY TO MANAGE GROWTH
 
    The Company's business plan will, if successfully implemented, result in
rapid expansion of its operations. Rapid expansion of the Company's operations
may place a significant strain on the Company's management, financial and other
resources. The Company's ability to manage future growth, should it occur, will
depend upon its ability to attract, train, assimilate and retain additional
qualified personnel, to monitor operations, control costs, maintain regulatory
compliance, maintain effective quality controls and significantly expand the
Company's internal management, technical, information and accounting systems.
There can be no assurance that the Company will successfully implement and
maintain such operational and financial systems or that it will successfully
obtain, integrate and utilize the management, operational and financial
resources necessary to manage a developing and expanding business in an
evolving, highly regulated and increasingly competitive industry. Any failure to
expand these areas and to implement and improve such systems, procedures and
controls in an efficient manner at a pace consistent with the growth of the
Company's business could have a material adverse effect on the business,
financial condition and results of operations of the Company and the ability of
the Company to make principal and interest payments on its indebtedness,
including the Notes.
 
                                       12
<PAGE>
    If the Company were unable to hire and train staff, purchase adequate
supplies of equipment, increase the capacity of its operational and accounting
information systems or successfully manage and integrate such additional
resources, customers could experience delays in connection of service and lower
levels of customer service. Failure by the Company to meet the demands of
customers and to manage the expansion of its business and operations could have
a material adverse effect on the Company's business, financial condition and
results of operations and the Company's ability to make principal and interest
payments on its indebtedness, including the Notes.
 
DEPENDENCE UPON NETWORK INFRASTRUCTURE
 
    The Company's success will depend upon the capacity, reliability and
security of its networks. The Company expects that a substantial portion of its
future revenues will be derived from the provision of tailored value-added
network services to its customers. The Company must continue to expand and adapt
its network infrastructure as the number of users and the amount of information
they wish to transfer increase and as customer requirements change. There can be
no assurance that the Company will be able to expand or adapt its network
infrastructure to meet additional demand or its customers' changing requirements
on a timely basis, at a commercially reasonable cost, or at all. Any failure of
the Company to expand its network infrastructure on a timely basis or adapt it
to either changing customer requirements or evolving industry standards could
have a material adverse effect on the Company's business, financial condition
and results of operations and the ability of the Company to make principal and
interest payments on its indebtedness, including the Notes.
 
    The backbone of the Company's network within Anaheim, California is a
50-mile fiber loop owned by the City of Anaheim and leased and operated by the
Company. Under an Agreement For Use of Operating Property between the City of
Anaheim and FirstWorld Anaheim, a wholly owned subsidiary of the Company
("FWA"), the Company's lease of the loop is subject to termination upon
customary default provisions, including failure to pay rent within the required
time period or a breach of its other material duties or obligations thereunder.
In addition, the Universal Telecommunications System Participation Agreement (as
amended, the "UTS Agreement") among the City of Anaheim, the Company and FWA
requires FWA to complete 90% of a designated portion of the Anaheim network by
December 31, 1998, plus a 180 day cure period. The Company already has satisfied
a requirement to complete 44% of such work by April 1, 1998. If FWA fails to
meet the 90% deadline, then the City may elect to terminate the Agreement for
Use of Operating Property and the UTS Agreement, or, in the alternative,
exercise its right to purchase all of FWA's outstanding stock. See
"Business--Agreements with the City of Anaheim and The Irvine Company--The City
of Anaheim." Any termination of the Agreement for Use of Operating Property or
the UTS Agreement, or the exercise by the City of Anaheim's right to purchase
all of FWA's outstanding stock, would have a material adverse effect on the
Company's business, financial condition and results of operations and the
Company's ability to make principal and interest payments on its indebtedness,
including the Notes.
 
RELIANCE ON THIRD PARTIES FOR ACCESS TO TELEPHONY SERVICES
 
   
    Because the Company expects to provide certain services through connections
supplied by ILECs and other providers, it is dependent upon the cooperation of
third party telecommunications providers, including certain of the Company's
major competitors, such as Pacific Bell, in providing access to their services.
The Company has entered into interconnection agreements with Pacific Bell and
GTE Corporation ("GTE"), which, among other things, establish the terms and
conditions for access to such networks for origination and termination of calls
and set pricing for unbundled network elements. The Company will need to enter
into similar agreements as it expands to areas where neither Pacific Bell nor
GTE is the ILEC. There can be no assurance that the Company will be able to
enter into additional interconnection agreements on favorable terms or at all.
Even when the Company has entered into an interconnection agreement, there can
be no assurance that the Company's orders for additional unbundled loops or
other
    
 
                                       13
<PAGE>
services will be fulfilled in a timely manner. Failure of other parties to
interconnection agreements to maintain equipment and provide service in a
reliable and timely manner may result in interrupted service to the Company's
customers and risk of loss of business. In addition, there can be no assurance
that the rates charged to the Company under interconnection agreements will
continue to allow the Company to offer its services at competitive prices.
 
    The Company provides long distance service, operator services, directory
assistance and calling card services under its own name pursuant to agreements
with Sprint. The Company has obtained volume discounts for a variety of services
the Company purchases from Sprint (including long distance), based on estimates
of the Company's monthly usage of such services. If the Company fails to meet
targeted usage (or in certain instances, exceeds targeted usage) the Company
must pay Sprint various monthly surcharges with respect to such services. The
most significant of these monthly surcharges relates to the required amount of
long distance service the Company purchases from Sprint. Beginning in August
1998, the Company will be required to purchase certain minimum monthly amounts
of long distance service (which minimum requirements increase over time) or pay
Sprint a penalty equal to a percentage of the Company's shortfall. To date, the
Company has not purchased in any one month the amount of long distance service
that the Company is required to purchase beginning in August 1998 nor can it be
certain when or if it will purchase such minimum amounts.
 
RISKS OF IMPLEMENTATION, SITES, EQUIPMENT AND SUITABLE INTERCONNECT ARRANGEMENTS
 
    The Company intends to develop and expand the Company's business and enter
new markets as described below under the caption "Business--Network Construction
Status and Proposed Expansion." There can be no assurance the Company will be
able to complete construction in Orange County or the San Gabriel Valley and
South Bay areas of Los Angeles County on the timetable and in the manner
currently planned or that it will be able to expand to new areas in the manner
currently contemplated. The development and expansion of the Company's business
into new markets will be dependent, among other things, upon the Company's
ability to lease or purchase suitable sites for its equipment, its ability to
negotiate suitable interconnection and co-location agreements with ILECs on
satisfactory terms and conditions and its ability to finance such expansion.
Pacific Bell has engaged in lobbying at the state and local levels and through
the media aimed at discouraging telecommunications cooperation agreements
between municipalities and private companies such as the Company. Such actions
on the part of Pacific Bell, if successful, could prevent the Company from
entering into future contracts similar to its agreement with the City of
Anaheim. These factors and others could adversely affect the expansion of the
Company's customer base and commencement of operations in new markets. The
failure by the Company to expand or enter new markets in accordance with its
plans would have a material adverse effect on the Company's business, financial
condition and results of operations and the Company's ability to make principal
and interest payments on its indebtedness, including the Notes.
 
COMPETITION
 
    The telecommunications services industry is highly competitive. The Company
has not obtained significant market share in any of the areas where it offers or
intends to offer services, nor does it expect to do so in the near future given
the size of the local telecommunications market, the intense competition therein
and the diversity of customer requirements. In each market area in which the
Company is authorized to provide services, the Company competes or will compete
with several other service providers and technologies. Certain bases of
competition in the Company's markets include price, performance, reliability of
service, ease of access and use, services offered, product bundling, customer
support, brand recognition and operating experience. Most of the Company's
competitors, particularly the applicable ILEC, have longer operating histories,
long-standing relationships with customers and suppliers in their respective
industries, greater name recognition and significantly greater financial,
technical and marketing resources than the Company. The Company faces intense
competition with respect to each of the services it offers. The Company cannot
predict the number of competitors that will emerge as a result of existing or
new federal and state legislative actions. See "--Regulation."
 
                                       14
<PAGE>
    TELEPHONY.  The Company's principal telephony competitors are the ILECs in
the areas served by the Company's networks. While the Interconnection Decisions
of the Federal Communications Commission ("FCC") (as defined herein) and the
Telecommunications Act of 1996 (the "Telecommunications Act") provide increased
business opportunities to CLECs and ICPs such as the Company, they also provide
the ILECs with increased pricing flexibility for their services and other
regulatory relief, which could have a material adverse effect on CLECs and ICPs,
including the Company. If the ILECs are allowed by regulators to lower their
rates for their services, engage in substantial volume and term discount pricing
practices for their customers, or seek to charge CLECs and ICPs substantial fees
for interconnection to the ILECs' networks, the results of operations of CLECs
and ICPs, including the Company, could be materially adversely affected.
 
   
    In late December 1997, the U.S. District Court for the Northern District of
Texas ruled that the Telecommunications Act unconstitutionally singled out the
RBOCs for punishment by prohibiting them from offering long distance services
within their service areas. The district court's decision has been stayed
pending appellate review by the United States Court of Appeals for the Fifth
Circuit, as to which briefing has now been completed. In addition, in May 1998
the United States Court of Appeals for the District of Columbia Circuit, ruling
in another case addressing whether RBOCs may provide "electronic publishing"
services, held that the Telecommunications Act does not violate constitutional
provisions relied on by the Texas district court in December 1997. However, if
upheld by the United States Court of Appeals for the Fifth Circuit (and by any
subsequent United States Supreme Court review), or if the stay is lifted, the
December 1997 Texas district court decision could present significant
opportunities for RBOCs, such as SBC Communications, Inc. ("SBC") and Pacific
Bell, to offer long distance services and to bundle their service offerings.
Although these companies would still require state public utilities commission
("PUC") approval to enter long distance markets prior to beginning service, the
ruling, if upheld, would provide them relief from significant federal regulatory
restrictions and allow them to become more formidable competitors of the
Company. In addition, on August 6, 1998 the FCC initiated a proceeding to allow
ILECs to offer DSL and other advanced telecommunications services. The FCC has
proposed to permit the offering of such services by ILECs on an unregulated
basis if certain separate subsidiary and interconnection requirements are met.
The outcome of this proceeding, and its ultimate effect on competition, are
uncertain.
    
 
   
    The Company also competes for telephony services with various CLECs in its
target markets, including MFS Communications, NEXTLINK Communications, Inc.
("NEXTLINK"), ICG Telecommunications, Inc. ("ICG"), GST Telecommunications, Inc.
("GST") and Teleport Communications Group, Inc. ("Teleport"). To date, the
Company has not encountered a high level of competition from CLECs or ICPs for
its targeted customers in its initial markets. The Company expects the level of
such competition to increase substantially in the future, and there can be no
assurance that the Company will be able to expand successfully, retain its
existing customers or price its products profitably in the presence of such
increased competition. The Company also faces, and expects to continue to face,
competition from other current and potential market entrants, including AT&T
Corp. ("AT&T"), MCI Communications Corporation ("MCI"), Sprint, WorldCom and
other IXCs, wireless telephone system operators and private networks built by
large end users. AT&T has indicated its intention to offer local
telecommunications services in certain U.S. markets, either directly or in
conjunction with CLECs or cable operators. In January 1998 AT&T announced a plan
to acquire Teleport, one of the Company's CLEC competitors. That acquisition, if
consummated, would allow AT&T to sell integrated local, long-distance and data
communications services to businesses in the areas served by Teleport, some of
which overlap areas targeted or served by the Company. AT&T has also announced
plans to merge with Tele-Communications, Inc. ("TCI"), the nation's largest
operator of cable television systems, and to provide telephone services over the
TCI cable plant. Sprint recently announced plans to deploy an advanced
telecommunications network intended to boost speed and capacity, cut costs and
provide an integrated platform to enter local markets, and has signed access
agreements with a number of RBOCs and GTE. WorldCom already has acquired MFS
Communications (one of the Company's CLEC competitors) and Brooks Fiber
Properties, Inc., both
    
 
                                       15
<PAGE>
   
major CLECs, and WorldCom has agreed to acquire MCI, subject to regulatory
approvals. Recently Ameritech Corp. ("Ameritech") and US West Inc. ("US West")
have announced plans to enter the long distance market by forming joint sales
ventures with Qwest Communications International Corp. ("Qwest"), a growing
provider of fiber optic-based telecommunications services. Although the legality
of these particular deals with Qwest have been challenged as a result of actions
brought by AT&T and MCI and remain subject to judicial and FCC review, a
continuing trend toward combinations and strategic alliances in the
telecommunications industry, including combinations or potential consolidations
among RBOCs or CLECs, or between IXCs and CLECs, could give rise to significant
new competitors for the Company. The Company also expects increased competition
from ILECs operating outside of their current local service areas, cable
television systems, electric utilities, microwave and other wireless carriers
and satellite licensees.
    
 
    INTERNET SERVICES.  The Internet services market is extremely competitive,
and the Company expects competition in this market to intensify in the future.
The Company's current and prospective competitors include many large companies
that have substantially greater market presence and financial, technical,
marketing and other resources than the Company. The Company competes (or in the
future is expected to compete) directly or indirectly with the following
categories of companies: (i) national and regional ISPs; (ii) established
on-line services; (iii) computer software and technology companies; (iv)
national telecommunications companies; (v) RBOCs; (vi) cable operators; and
(vii) nonprofit or educational ISPs. The entry of new participants from these
categories and the potential entry of competitors from other categories (such as
computer hardware manufacturers) would result in substantially greater
competition for the Company.
 
    ADVANCED NETWORK SERVICES.  In the markets for LAN/WAN services and other
advanced network services, the Company will face competition from a number of
companies focused on the LAN and WAN market, including companies with
significantly greater financial resources, more extensive business experience,
and greater market and service capabilities than the Company. In particular, the
Company will be required to compete with companies that design and manufacture
products for the LAN and WAN markets and large system integrators. The Company
also competes with the ILEC for data connectivity services. Pacific Bell, for
example, recently announced that it intends to offer DSL services over its
existing networks. Substantially all of the Company's current and prospective
competitors in the markets for advanced network services have greater market
presence and financial, technical, marketing and other resources than the
Company.
 
RISK OF SYSTEM FAILURE; SECURITY RISKS
 
   
    The Company's success in marketing its services to business customers
requires the Company to provide reliable service. The Company's networks are
subject to physical damage, power loss, capacity limitations, software defects,
breaches of security (by computer virus, break-ins or otherwise) and other
factors which may cause interruptions in service or reduced capacity for the
Company's customers. FirstWorld utilizes various procedures to minimize security
risks. The Company currently provides its customers their own physical and
permanent virtual circuits throughout the FirstWorld network. The Company also
utilizes a Fire Wall to protect its internet customers. In addition, the
Company's own fiber network is inaccessible, in that it has no electrical
interfaces that allow the possibility of monitoring. All termination points and
manholes within Firstworld's own fiber network are locked and secured. There can
be no assurance, however, that these security procedures will prove to be
adequate. Moreover, the Company's current, and certain of its planned networks,
are located in an area prone to earthquakes. An earthquake or other natural
disaster affecting the normal operations of the Company or the ILECs with which
the Company does business could seriously impair the Company's ability to
provide service to customers. Interruptions in service, capacity limitations or
security breaches could have a material adverse effect on customer acceptance
and, therefore, on the Company's business. Certain aspects of the Company's
network architecture involve new applications of equipment which may result in
technical issues that may not be easily resolved. Although the Company generally
seeks to limit its liability through its
    
 
                                       16
<PAGE>
contracts with customers, there can be no assurance that the Company will not be
held liable for damages resulting from service failures. Lapses in service or
reliability also could lead to a loss of customers, which could have a material
adverse effect on the cash flow available to the Company to make principal and
interest payments on its indebtedness, including the Notes. In addition, while
the Company believes it has insurance comparable to that maintained by other
companies in the industry, the Company's central office facility is not fully
insured against, and the Anaheim fiber loop is not insured against, earthquake
loss.
 
CHANGES IN TECHNOLOGY, SERVICES AND INDUSTRY STANDARDS
 
    The telecommunications industry has been characterized by rapid
technological advances, changes in end user requirements, frequent new service
introductions, evolving industry standards and decreases in the cost of
equipment and the pricing of services. The Company expects these changes to
continue, and believes that its long-term success will increasingly depend on
its ability to offer services that exploit advanced technologies and anticipate
or adapt to evolving industry standards. There can be no assurance that the
Company's services will not become economically or technically outmoded by
technology or services now existing or developed and implemented in the future
or that the Company will have sufficient resources to develop or acquire new
technologies or to introduce new services capable of competing with future
technologies or service offerings. The effect on the Company of technological
changes cannot be predicted and could be material and adverse to the Company's
business, financial condition and results of operations and the Company's
ability to make principal and interest payments on its outstanding indebtedness,
including the Notes.
 
SIGNIFICANT CAPITAL REQUIREMENTS
 
   
    The development of the Company's business and deployment of its services and
systems will require significant additional capital to fund capital
expenditures, working capital, debt service and operating losses. The Company's
principal capital expenditure requirements involve the purchase, installation
and construction of network operations centers, other network infrastructure and
customer located equipment ("CLE"). The Company believes that the proceeds from
the Private Note Offering and the concurrent investment by Colorado Spectra 3,
LLC, a Colorado limited liability Company controlled by Donald L. Sturm
("Spectra 3") and Enron of an aggregate amount of $20 million (the "Additional
Equity Investment") will be sufficient to fund the Company's aggregate capital
expenditures and working capital requirements, including operating losses,
associated with its roll-out into the Orange County, San Gabriel and South Bay
areas. The Company expects that as it expands its networks beyond these areas,
its capital requirements will require it to obtain additional financing, which
may include commercial bank borrowings, vendor financing or the sale or issuance
of equity and debt securities either through one or more offerings or to one or
more strategic investors. If demand for the Company's services is materially
different than expected, the Company may require additional financing at an
earlier date, although the Company believes that it would be able to reduce
certain costs that are, to a large extent, demand-driven. There can be no
assurance that the Company will be successful in raising additional capital in
sufficient amounts to fund its strategic objectives, or that such funds, if
available, will be available on terms that the Company will consider acceptable.
The Company terminated its revolving credit facility (the "Credit Facility") in
connection with the Private Note Offering, and there can be no assurance that
the Company will be able to enter into a new facility on terms acceptable to the
Company. Failure to raise sufficient funds may require the Company to modify,
delay or abandon some of its planned future expansion or expenditures, which
could have a material adverse effect on the Company's business, financial
condition and results of operations and the Company's ability to make principal
and interest payments on its indebtedness, including the Notes. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources." In addition, the Indenture imposes
operating and financial restrictions on the Company and its subsidiaries. These
restrictions affect, and in certain cases significantly limit or prohibit, among
other things, the ability of the Company and its subsidiaries to incur
additional indebtedness, pay dividends or make distributions in respect of the
Company's or such subsidiaries' capital stock, make other restricted payments,
enter into sale and leaseback transactions, create liens upon assets,
    
 
                                       17
<PAGE>
enter into transactions with affiliates or related persons, sell assets, or
consolidate, merge or sell all or substantially all of their assets. See
"Description of the Notes." There can be no assurance that such covenants will
not adversely affect the Company's ability to finance its future operations or
capital needs or to engage in other business activities that may be in the
Company's interest.
 
DEPENDENCE ON KEY PERSONNEL
 
    The success of the Company depends, in large part, upon the continuing
contributions of its key technical, marketing, sales and management personnel.
The loss of the services of one or more key people could have a material adverse
effect upon the business, financial condition and results of operations of the
Company. The Company does not have employment agreements with any of its
officers or employees, nor does it maintain any key man life insurance. The
Company's future success also is dependent upon its continuing ability to
attract and retain additional highly qualified personnel. The Company currently
is seeking to hire a number of additional senior management personnel.
Competition for such personnel is intense, and the Company's inability to
attract and retain additional key employees could have a material adverse effect
on the Company's business, financial condition and results of operations and the
Company's ability to make principal and interest payments on its indebtedness,
including the Notes. There can be no assurance that the Company's existing
personnel will continue to be employed by the Company or that the Company will
be able to attract and retain qualified personnel in the future. See
"Management."
 
GOVERNMENT REGULATION
 
   
    The Company is subject to regulation by the FCC and by state public service
and public utility commissions as a provider of telecommunications services.
Changes in existing policies or regulations in the state and localities served
by the Company or by the FCC could materially and adversely affect the Company's
business, financial condition and results of operations and its ability to repay
its indebtedness, including the Notes, particularly if those policies make it
more difficult to obtain unbundled network elements from ILECs or other
telecommunications services at competitive prices, or otherwise increase the
cost and regulatory burdens of providing services. There can be no assurance
that regulatory authorities in the areas served by the Company or the FCC will
refrain from taking actions having an adverse effect on the business or
financial condition or results of operations of the Company. The
Telecommunications Act has significantly altered regulation of the
telecommunications industry by preempting state and local laws to the extent
that they prevent competition and by imposing a variety of new duties on LECs
and ILECs in order to promote competition in local exchange and access services.
Although the Company believes that the Telecommunications Act and other trends
in federal and state legislation and regulation that favor increased competition
are to the Company's advantage, there can be no assurance that the increased
competitive opportunities or other changes in current regulations or future
regulations at the federal or state level will not have a material adverse
effect on the Company's business, financial condition and results of operations
or its ability to make principal and interest payments on its indebtedness,
including the Notes. See "Business--Regulation."
    
 
POTENTIAL LIABILITY FOR INFORMATION DISSEMINATED THROUGH NETWORK
 
    The law relating to the liability of on-line service providers, private
network operators and Internet service providers for information carried on or
disseminated through the facilities of their networks is currently unsettled.
Several lawsuits seeking a judgment of such liability are pending. While such
claims have not been asserted against the Company, there can be no assurance
that such claims will not be asserted in the future, or if asserted, will not be
successful. The Telecommunications Act prohibits and imposes criminal penalties
and civil liability for using an interactive computer service for transmitting
certain types of information and content, such as obscene communications.
Numerous states have adopted or are currently considering similar types of
legislation. The imposition upon the Company, ISPs or Web server hosts of
potential liability for materials carried on or disseminated through their
systems could require the Company to implement measures to reduce its exposure
to such liability, which may require the expenditure of substantial resources or
the discontinuation of certain product or service offerings. Further,
 
                                       18
<PAGE>
the costs incurred in defending against any such claims and potential adverse
outcomes of such claims could have a material adverse effect on the Company's
financial condition and results of operations. The Company believes that it is
currently unclear whether the Telecommunications Act prohibits or imposes
liability for any services provided by the Company should the content of
information transmitted be subject to the statute.
 
EFFECTIVE SUBORDINATION OF NOTES; HOLDING COMPANY STRUCTURE
 
   
    The Company is a holding company that will derive substantially all of its
operating income, if any, from its subsidiaries. The holders of the Notes will
have no direct claim against the subsidiaries for payment under the Notes. The
Company's subsidiaries are separate and distinct legal entities and will have no
obligation, contingent or otherwise, to pay any dividend or make any other
distribution to the Company, or otherwise to pay amounts due with respect to the
Notes or to make funds available for such payments. The Company must rely on
dividends and other payments from its subsidiaries or must raise funds in a
public or private equity or debt offering or sell assets to generate the funds
necessary to meet its obligations, including the payment of principal and
interest on the Notes. There can be no assurance that the Company would be able
to obtain such funds on acceptable terms or at all. FWA has an obligation to
fund a reserve account with a portion of "net revenues" (as defined in the UTS
Agreement) derived from the Anaheim network. See "Business--Agreements with the
City of Anaheim and The Irvine Company-- The City of Anaheim--Universal
Telecommunications System Participation Agreement." There currently are no other
restrictions on payments from the Company's subsidiaries to the Company and the
Indenture contains covenants that restrict the ability of the Company's
subsidiaries to enter into any agreement limiting certain distributions and
transfers, including dividends, to the Company.
    
 
   
    The Notes will be effectively subordinated in right of payment to all
existing and future indebtedness and liabilities of the Company's subsidiaries.
The total liabilities of the Company's subsidiaries as of June 30, 1998 were
approximately $28.3 million. In addition, the Indenture will permit the Company
and its subsidiaries to incur additional indebtedness, subject to the
restrictions set forth in the Indenture. See "Description of the Notes--Certain
Covenants--Limitation on Consolidated Indebtedness." Consequently, in the event
of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding
with respect to the Company's subsidiaries, the holders of any indebtedness of
the Company's subsidiaries will be entitled to payment thereof from the assets
of such subsidiaries prior to the holders of any general unsecured obligations
of the Company, including the Notes.
    
 
   
    The Notes also are unsecured and will be effectively subordinated to any
secured indebtedness of the Company to the extent of the value of the assets
securing such indebtedness. The Indenture will permit the Company and its
subsidiaries to incur additional secured indebtedness, including purchase money
indebtedness in unlimited amounts, and indebtedness of up to $75 million
pursuant to one or more credit facilities. In the event of a bankruptcy,
liquidation, dissolution, reorganization or similar proceeding with respect to
the Company, the holders of any secured indebtedness will be entitled to proceed
against the collateral that secures such secured indebtedness and such
collateral will not be available for satisfaction of any amounts owed under the
Notes. See "Description of Exchange Notes--Certain Covenants--Limitation on
Consolidated Indebtedness."
    
 
GEOGRAPHICAL CONCENTRATION OF THE COMPANY'S CURRENT OPERATIONS
 
    The Company's first network clusters will serve markets surrounding
metropolitan Los Angeles. Unless and until the Company expands beyond Southern
California, the Company's geographic focus may make it more vulnerable than its
competitors to economic downturns and market changes in the region or cities in
which it operates. A downturn in the economies of the region or cities in which
the Company operates or a substantial increase in competition within this region
or these cities, could have a material adverse effect on the Company's business,
financial condition and results of operations and the Company's ability to make
principal and interest payments on its indebtedness, including the Notes.

CONTROL BY PRINCIPAL STOCKHOLDERS; POTENTIAL CONFLICTS OF INTEREST
 
   
    As of May 31, 1998, Spectra 1, LLC, a Colorado limited liability company
controlled by Donald L. Sturm ("Spectra 1"), Colorado Spectra 2, LLC, a Colorado
limited liability company controlled by Donald L. Sturm ("Spectra 2"), and
Spectra 3 (together with Spectra 1 and Spectra 2, the "Sturm Entities")
beneficially owned approximately 37.4% of the Company's outstanding common
stock, including 49.3% of the Company's outstanding Series A Common Stock, which
possesses super-voting rights. By virtue of the super-voting rights of the
Series A Common Stock, the Sturm Entities control approximately 46.7% of the
voting power of the Company's outstanding common stock. As of May 31, 1998,
Enron beneficially owned approximately 32.1% of the Company's outstanding common
stock, including 49.3% of the Company's Series A Common Stock. By virtue of the
super-voting rights of the Series A Common Stock, Enron controls approximately
45.5% of the outstanding voting power of the Company's common stock. In
addition, the Sturm Entities are entitled to appoint three directors and Enron
is entitled to appoint two directors of the Company's seven-person Board of
Directors pursuant to a Securityholders Agreement (the "Securityholders
Agreement") among the Sturm Entities, Enron and the Company, and Donald L. Sturm
is the Company's Chairman of the Board and Chief Executive Officer. As a result
of their respective ownership interests and Board designees, the Sturm Entities
and Enron control the Company. The Sturm Entities and Enron have the ability to
control the election of at least a majority of the directors of the Company and
any other major decisions involving the Company or its assets. The ownership and
voting interests possessed by the Sturm Entities and Enron make it impossible
for a third party to acquire control of the Company without the consent of the
Sturm Entities and Enron.
    
 
    In addition to their investments in the Company, the Sturm Entities and
Enron have investments, and may in the future make investments, in other
telecommunications companies and ventures, including competitors of the Company.
As a result, conflicts may arise in the negotiation and enforcement of
arrangements entered into by the Company and entities in which the Sturm
Entities or Enron have an interest. In addition, the Company, the Sturm Entities
and Enron have agreed that the Sturm Entities and Enron are under no obligation
to bring to the Company any investment or business opportunities of which they
become aware, even if such opportunities are within the scope and objectives of
the Company. The Sturm Entities and Enron may have an interest in pursuing
acquisitions, divestitures, financings or other transactions that, in their
judgment, could enhance their equity investment, even though such transactions
might involve risk to the holders of the Notes. See "Principal Stockholders" and
"Certain Transactions."
 
ABSENCE OF A PUBLIC MARKET FOR THE NOTES; RESTRICTIONS ON TRANSFER
 
    As of the date hereof, the only registered holder of Private Notes is Cede &
Co., as the nominee of DTC. The Company believes that, as of the date hereof,
such holder is not an "affiliate" (as such term is defined in Rule 405 under the
Securities Act) of the Company. Prior to the Private Note Offering there had
been no market for the Notes, and there can be no assurance that such a market
will develop or, if such a market develops, as to the liquidity of such market.
The Exchange Notes will not be listed on any securities exchange, but the
Private Notes are eligible for trading in the PORTAL market. The Exchange Notes
are new securities for which there is currently no market. The Initial
Purchasers have advised the Company that they intend to make a market in the
Exchange Notes, as well as the Private Notes, as permitted by applicable laws
and regulations; however, the Initial Purchasers are not obligated to do so, and
may discontinue any such market making activities at any time without notice. In
addition, such market making activity may be limited during the Exchange Offer
and the pendency of the Shelf Registration Statement (as defined in the
Registration Rights Agreement). Therefore, there can be no assurance that an
active market for the Exchange Notes will develop. If a trading market develops
for the Exchange Notes future trading prices of such securities will depend on
many factors, including, among other things, prevailing interest rates, the
market for similar securities, the performance of the Company and other factors.
In addition, based on such factors, the Exchange Notes may trade at a discount
from their initial offering price. See "The Exchange Offer" and "Plan of
Distribution."

ORIGINAL ISSUE DISCOUNT; POSSIBLE UNFAVORABLE TAX AND OTHER LEGAL CONSEQUENCES
  FOR HOLDERS OF NOTES AND THE COMPANY
 
    The Private Notes were, and the Exchange Notes will be, issued at a
substantial discount from their stated principal amount at maturity.
Consequently, purchasers of Exchange Notes should be aware that, although there
will be no periodic payments of cash interest on the Exchange Notes prior to
October 15, 2003, original issue discount (that is, the difference between the
stated redemption price at maturity and the issue price of the Exchange Notes)
will accrete from the issue date of the Exchange Notes and will be includable as
interest income periodically (for periods ending on or prior to April 15, 2003)
in a holder's gross income for U.S. federal income tax purposes in advance of
receipt of the cash payments to which the income is attributable. See "Certain
United States Federal Income Tax Considerations" for a more detailed discussion
of the federal income tax consequences to the holders of the Exchange Notes
regarding the purchase, ownership and disposition of the Exchange Notes.
 
    If a bankruptcy case is commenced by or against the Company under U.S.
bankruptcy laws after the issuance of the Notes, the claim of a holder of Notes
with respect to the principal amount thereof may be limited to an amount equal
to the sum of (i) the initial offering price and (ii) that portion of the
original issue discount that is not deemed to constitute "unmatured interest"
for purposes of the U.S. bankruptcy laws. Any original issue discount that was
not amortized as of any such bankruptcy filing would constitute "unmatured
interest."
 
    The Notes may be subject to the high yield discount obligation rates, which
will defer and may, in part, eliminate the Company's ability to deduct for U.S.
federal income tax purposes the original issue discount attributable to the
Notes. Accordingly, the Company's after tax cash flow might be less than if the
original issue discount on the Notes were deductible when it accrued.
 
YEAR 2000 ISSUES
 
   
    The Company is continuing to determine whether its systems and its vendors'
systems will require updating to continue to function properly beyond 1999. As
the Company adds new features to its network it will continue to evaluate the
functionality of such features beyond 1999. Although the Company does not expect
to incur significant expenditures to upgrade its network to address Year 2000
problems, there can be no assurance that the Company will be able to identify
all Year 2000 problems in its systems in advance of their occurrence or that the
Company will be able to successfully remedy any problems. In addition, to the
extent that the Company's suppliers, including the ILECs over whose networks the
Company provides certain of its services, or customers fail to address Year 2000
issues in a timely and effective manner, the Company's ability to provide
uninterrupted, reliable service to customers serviced through such networks may
be adversely affected. Moreover, the profitability and stability of the
Company's customers may be adversely affected by Year 2000 problems not related
to their relationships with the Company. The expenses associated with the
Company's efforts to remedy any Year 2000 problems, the expenses or liabilities
to which the Company may become subject as a result of such problems or the
impact of Year 2000 problems on the ability of existing or future customers to
do business with the Company could have a material adverse effect on the
Company's business, prospects, operating results, financial condition and its
ability to service and pay its indebtedness, including the Notes.
    
 
RISKS REGARDING FORWARD LOOKING STATEMENTS
 
   
    The statements contained in this Prospectus that are not historical facts
are forward-looking statements, which can be identified by the use of
forward-looking terminology such as "believes," "expects," "may," "will,"
"should" or "anticipates" or the negative thereof or other variations thereon or
comparable terminology, or by discussions of strategy that involve risks and
uncertainties. The Company wishes to caution the reader that these
forward-looking statements, such as those relating to the Company's plans to
build networks in new areas, its anticipation of revenues from designated
markets and statements
    
 
                                       21
<PAGE>
regarding the development of the Company's business, the markets for the
Company's services and products, the Company's anticipated capital expenditures,
regulatory reform and other statements contained herein regarding matters that
are not historical facts, are only predictions. No assurance can be given that
the expected future results will be achieved; actual events or results may
differ materially as a result of risks facing the Company or other external
events or due to decisions made by the Company in the future. The risks facing
the Company include, but are not limited to, those relating to the Company's
ability to successfully market its services to current and new customers, access
markets, design and construct fiber optic networks, install cable and
facilities, including switching electronics, and obtain rights-of-way, building
access rights and any required governmental authorizations and permits, all in a
timely manner, at reasonable costs and on satisfactory terms and conditions, as
well as regulatory, legislative and judicial developments that could cause
actual results to differ materially from the future results indicated, expressed
or implied, in such forward-looking statements.

                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
    The Private Notes were sold by the Company on April 13, 1998 (the "Closing
Date") to the Initial Purchasers pursuant to the Purchase Agreement. The Initial
Purchasers subsequently sold the Private Notes to "qualified institutional
buyers" ("QIBs"), as defined in Rule 144A under the Securities Act ("Rule
144A"), in reliance on Rule 144A. As a condition to the sale of the Private
Notes, the Company and the Initial Purchasers entered into the Registration
Rights Agreement on April 13, 1998. Pursuant to the Registration Rights
Agreement, the Company agreed that, unless the Exchange Offer is not permitted
by applicable law or Commission policy, it would (i) file with the Commission a
Registration Statement under the Securities Act with respect to the Exchange
Notes within 90 days after the Closing Date, (ii) use its best efforts to cause
such Registration Statement to become effective under the Securities Act within
150 days after the Closing Date and (iii) commence the Exchange Offer and use
its best efforts to issue, on or prior to 30 days after the date on which the
Registration Statement was declared effective by the Commission, Exchange Notes
in exchange for all Private Notes tendered prior thereto in the Exchange Offer.
A copy of the Registration Rights Agreement has been filed as an exhibit to the
Registration Statement. The Registration Statement is intended to satisfy
certain of the Company's obligations under the Registration Rights Agreement and
the Purchase Agreement.
 
RESALE OF THE EXCHANGE NOTES
 
    With respect to the Exchange Notes, based upon an interpretation by the
staff of the Commission set forth in certain no-action letters issued to third
parties, the Company believes that a holder (other than (i) a broker-dealer who
purchases such Exchange Notes directly from the Company to resell pursuant to
Rule 144A or any other available exemption under the Securities Act or (ii) any
such holder that is an "affiliate" of the Company within the meaning of Rule 405
under the Securities Act) who exchanges Private Notes for Exchange Notes in the
ordinary course of business and who is not participating, does not intend to
participate, and has no arrangement with any person to participate, in a
distribution of the Exchange Notes, will be allowed to resell Exchange Notes to
the public without further registration under the Securities Act and without
delivering to the purchasers of the Exchange Notes a prospectus that satisfies
the requirements of Section 10 of the Securities Act. However, if any holder
acquires Exchange Notes in the Exchange Offer for the purpose of distributing or
participating in the distribution of the Exchange Notes or is a broker-dealer,
such holder cannot rely on the position of the staff of the Commission
enumerated in certain no-action letters issued to third parties and must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale transaction, unless an exemption from registration
is otherwise available. Each broker-dealer that receives Exchange Notes for its
own account in exchange for Private Notes, where such Private Notes were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of
Exchange Notes received in exchange for Private Notes where such Private Notes
were acquired by such broker-dealer as a result of market-making or other
trading activities. Pursuant to the Registration Rights Agreement, the Company
has agreed to make this Prospectus, as it may be amended or supplemented from
time to time, available to broker-dealers for use in connection with any resale
for one full year after the Expiration Date. See "Plan of Distribution."
 
TERMS OF THE EXCHANGE OFFER
 
    Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Private
Notes validly tendered and not withdrawn prior to
 
                                       23
<PAGE>
the Expiration Date. The Company will issue $1,000 in principal amount at
maturity of Exchange Notes in exchange for each $1,000 in principal amount at
maturity of outstanding Private Notes surrendered pursuant to the Exchange
Offer. Private Notes may be tendered only in integral multiples of $1,000.
 
    The form and terms of the Exchange Notes are the same as the form and terms
of the Private Notes except that (i) the exchange will have been registered
under the Securities Act, and, therefore, the Exchange Notes will not bear
legends restricting the transfer thereof and (ii) holders of the Exchange Notes
will not be entitled to certain rights of holders of the Private Notes under the
Registration Rights Agreement, which rights will terminate upon the consummation
of the Exchange Offer. The Exchange Notes will evidence the same indebtedness as
the Private Notes (which they replace) and will be issued under, and be entitled
to the benefits of, the Indenture, which also authorized the issuance of the
Private Notes, such that both series of Notes will be treated as a single class
of debt securities under the Indenture.
 
    As of the date of this Prospectus, $470,000,000 in aggregate principal
amount at maturity of the Private Notes are outstanding. Only a registered
holder of the Private Notes (or such holder's legal representative or
attorney-in-fact) as reflected on the records of the Trustee under the Indenture
may participate in the Exchange Offer. There will be no fixed record date for
determining registered holders of the Private Notes entitled to participate in
the Exchange Offer.
 
    Holders of the Private Notes do not have any appraisal or dissenters' rights
under the Indenture in connection with the Exchange Offer. The Company intends
to conduct the Exchange Offer in accordance with the provisions of the
Registration Rights Agreement and the applicable requirements of the Securities
Act, the Securities Exchange Act of 1934, as amended (the "Exchange Act") and
the rules and regulations of the Commission thereunder.
 
    The Company shall be deemed to have accepted validly tendered Private Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Private Notes for the purposes of receiving the Exchange Notes from the
Company.
 
    Holders who tender Private Notes in the Exchange Offer will not be required
to pay brokerage commissions or fees or, subject to the instructions in the
Letter of Transmittal, transfer taxes with respect to the exchange of Private
Notes pursuant to the Exchange Offer. The Company will pay all charges and
expenses, other than certain applicable taxes described below, in connection
with the Exchange Offer. See "--Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
   
    The term "Expiration Date" shall mean 5:00 p.m. New York City time on
           , 1998, unless the Company, in its reasonable discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.
    
 
    In order to extend the Exchange Offer, the Company will (i) notify the
Exchange Agent of any extension by oral or written notice and (ii) mail to the
registered holders an announcement thereof which shall include disclosure of the
approximate number of Private Notes deposited to date, each prior to 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Date.
 
    The Company reserves the right, in its reasonable discretion, (i) to delay
accepting any Private Notes, (ii) to extend the Exchange Offer or (iii) if any
conditions set forth below under "--Conditions" shall not have been satisfied,
to terminate the Exchange Offer by giving oral or written notice of such delay,
extension or termination to the Exchange Agent. Any such delay in acceptance,
extension, termination or amendment will be followed as promptly as practicable
by oral or written notice thereof to the registered holders. If the Exchange
Offer is amended in a manner determined by the Company to constitute a material
change, the Company will promptly disclose such amendment by means of a
prospectus supplement that will be distributed to the registered holders, and
the Company will extend the Exchange Offer
 
                                       24
<PAGE>
for a period of five to ten business days, depending upon the significance of
the amendment and the manner of disclosure to the registered holders, if the
Exchange Offer would otherwise expire during such five to ten business day
period.
 
ACCRETION OF THE EXCHANGE NOTES AND THE PRIVATE NOTES; INTEREST
 
    The Private Notes will continue to accrete in principal amount through (but
not including) the date of issuance of the Exchange Notes. Any Private Notes not
tendered or accepted for exchange will continue to accrete in principal amount
at the rate of 13% per annum through April 15, 2003 and thereafter cash interest
will accrue and be payable in accordance with its terms. From and after the date
of issuance of the Exchange Notes, the Exchange Notes shall accrete in principal
amount at the rate of 13% per annum, but no cash interest will accrue or be
payable in respect of the Exchange Notes prior to April 15, 2003. Thereafter,
the Exchange Notes will bear interest at a rate equal to 13% per annum. Interest
on the Exchange Notes will be payable semi-annually in arrears on April 15 and
October 15 of each year, commencing on October 15, 2003.
 
PROCEDURES FOR TENDERING
 
    Only a registered holder of Private Notes may tender such Private Notes in
the Exchange Offer. To tender in the Exchange Offer, a holder of Private Notes
must complete, sign and date the Letter of Transmittal, or a facsimile thereof,
have the signatures thereon guaranteed if required by the Letter of Transmittal,
and mail or otherwise deliver such Letter of Transmittal or such facsimile to
the Exchange Agent at the address set forth below under "--Exchange Agent" for
receipt prior to the Expiration Date. In addition, either (i) certificates for
such Private Notes must be received by the Exchange Agent along with the Letter
of Transmittal, (ii) a timely confirmation of a book-entry transfer (a
"Book-Entry Confirmation") of such Private Notes, if such procedure is
available, into the Exchange Agent's account at the Depositary pursuant to the
procedure for book-entry transfer described below, must be received by the
Exchange Agent prior to the Expiration Date or (iii) the holder must comply with
the guaranteed delivery procedures described below.
 
    The tender by a holder that is not withdrawn prior to the Expiration Date
will constitute an agreement between such holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the Letter
of Transmittal.
 
    THE METHOD OF DELIVERY OF PRIVATE NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR PRIVATE NOTES SHOULD BE
SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
    Any beneficial owner(s) of the Private Notes whose Private Notes are
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee and who wishes to tender should contact the registered holder
promptly and instruct such registered holder to tender on such beneficial
owner's behalf. If such beneficial owner wishes to tender on such owner's own
behalf, such owner must, prior to completing and executing the Letter of
Transmittal and delivering such owner's Private Notes, either make appropriate
arrangements to register ownership of the Private Notes in such owner's name or
obtain a properly completed bond power from the registered holder. The transfer
of registered ownership may take considerable time.
 
                                       25
<PAGE>
    Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "--Withdrawal of Tenders"), as the case may be, must be guaranteed by
an Eligible Institution (as defined below) unless the Private Notes tendered
pursuant thereto are tendered (i) by a registered holder who has not completed
the box titled "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. In the event that signatures on
a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantee must be made by a member firm of a
registered national securities exchange or of the National Association of
Securities Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States or an "eligible guarantor institution" within
the meaning of Rule 17Ad-15 under the Exchange Act which is a member of one of
the recognized signature guarantee programs identified in the Letter of
Transmittal (an "Eligible Institution").
 
    If the Letter of Transmittal is signed by a person other than the registered
holder of any Private Notes listed therein, such Private Notes must be endorsed
or accompanied by a properly completed bond power, signed by such registered
holder as such registered holder's name appears on such Private Notes.
 
    If the Letter of Transmittal or any Private Notes or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by the Company,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter of Transmittal.
 
    The Exchange Agent and the Depositary have confirmed that any financial
institution that is a participant in the Depositary's system may utilize the
Depositary's Automated Tender Offer Program to tender Private Notes.
 
    All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Private Notes will be determined
by the Company in its sole discretion, which determination will be final and
binding. The Company reserves the absolute right to reject any and all Private
Notes not properly tendered or any Private Notes the Company's acceptance of
which would, in the opinion of counsel for the Company, be unlawful. The Company
also reserves the right to waive any defects, irregularities or conditions of
tender as to particular Private Notes. The Company's interpretation of the terms
and conditions of the Exchange Offer (including the instructions in the Letter
of Transmittal) will be final and binding on all parties. Unless waived, any
defects or irregularities in connection with tenders of Private Notes must be
cured within such time as the Company shall determine. Although the Company
intends to notify holders of defects or irregularities with respect to tenders
of Private Notes, neither the Company, the Exchange Agent nor any other person
shall incur any liability for failure to give such notification. Tenders of
Private Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived.
 
    While the Company has no present plan to acquire any Private Notes that are
not tendered in the Exchange Offer or to file a registration statement to permit
resales of any Private Notes that are not tendered pursuant to the Exchange
Offer, the Company reserves the right in its sole discretion to purchase or make
offers for any Private Notes that remain outstanding subsequent to the
Expiration Date or, as set forth below under "--Conditions," to terminate the
Exchange Offer and, to the extent permitted by applicable law, purchase Private
Notes in the open market, in privately negotiated transactions or otherwise. The
terms of any such purchases or offers could differ from the terms of the
Exchange Offer.
 
    By tendering, each holder of Private Notes will represent to the Company
that, among other things, (i) Exchange Notes to be acquired by such holder of
Private Notes in connection with the Exchange Offer are being acquired by such
holder in the ordinary course of the respective business of such holder, (ii)
such holder has no arrangement or understanding with any person to participate
in the distribution of the Exchange Notes, (iii) if such holder is a resident of
the State of California, it falls under the self-executing institutional
investor exemption set forth under Section 25102(i) of the Corporate Securities
Law of 1968 and Rules 260.102.10 and 260.105.14 of the California Blue Sky
Regulations, (iv) if such holder is a
 
                                       26
<PAGE>
resident of the Commonwealth of Pennsylvania, it falls under the self-executing
institutional investor exemption set forth under Sections 203(c), 102(d) and (k)
of the Pennsylvania Securities Act of 1972, Section 102.111 of the Pennsylvania
Blue Sky Regulations and an interpretive opinion dated November 16, 1985, (v)
such holder acknowledges and agrees that any person who is a broker-dealer
registered under the Exchange Act or is participating in the Exchange Offer for
the purposes of distributing the Exchange Notes must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with a secondary resale transaction of the Exchange Notes acquired by
such person and cannot rely on the position of the staff of the Commission set
forth in certain no-action letters, (vi) such holder understands that a
secondary resale transaction described in clause (v) above and any resales of
Exchange Notes obtained by such holder in exchange for Private Notes acquired by
such holder directly from the Company should be covered by an effective
registration statement containing the selling securityholder information
required by Item 507 or Item 508, as applicable, of Regulation S-K of the
Commission and (vii) such holder is not an "affiliate," as defined in Rule 405
under the Securities Act, of the Company. If the holder is a broker-dealer that
will receive Exchange Notes for such holder's own account in exchange for
Private Notes that were acquired as a result of market-making activities or
other trading activities, such holder will be required to acknowledge in the
Letter of Transmittal that such holder will deliver a prospectus in connection
with any resale of such Exchange Notes; however, by so acknowledging and by
delivering a prospectus, such holder will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
RETURN OF PRIVATE NOTES
 
    If any tendered Private Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer or if Private Notes are withdrawn
or are submitted for a greater principal amount than the holders desire to
exchange, such unaccepted, withdrawn or non-exchanged Private Notes will be
returned without expense to the tendering holder thereof (or, in the case of
Private Notes tendered by book-entry transfer into the Exchange Agent's account
at the Depositary pursuant to the book-entry transfer procedures described
below, such Private Notes will be credited to an account maintained with the
Depositary) as promptly as practicable.
 
BOOK-ENTRY TRANSFER
 
    The Exchange Agent will make a request to establish an account with respect
to the Private Notes at the Depositary for purposes of the Exchange Offer within
two business days after the date of this Prospectus, and any financial
institution that is a participant in the Depositary's systems may make book-
entry delivery of Private Notes by causing the Depositary to transfer such
Private Notes into the Exchange Agent's account at the Depositary in accordance
with the Depositary's procedures for transfer. However, although delivery of
Private Notes may be effected through book-entry transfer at the Depositary, the
Letter of Transmittal or facsimile thereof, with any required signature
guarantees and any other required documents, must, in any case, be transmitted
to and received by the Exchange Agent at the address set forth below under
"--Exchange Agent" on or prior to the Expiration Date or pursuant to the
guaranteed delivery procedures described below.
 
GUARANTEED DELIVERY PROCEDURES
 
    Holders who wish to tender their Private Notes and (i) whose Private Notes
are not immediately available or (ii) who cannot deliver their Private Notes,
the Letter of Transmittal or any other required documents to the Exchange Agent
prior to the Expiration Date, may effect a tender if:
 
        (a) The tender is made through an Eligible Institution;
 
        (b) Prior to the Expiration Date, the Exchange Agent receives from such
    Eligible Institution a properly completed and duly executed Notice of
    Guaranteed Delivery substantially in the form
 
                                       27
<PAGE>
   
    provided by the Company (by facsimile transmission, mail or hand delivery)
    setting forth the name and address of the holder, the certificate number(s)
    of such Private Notes and the principal amount at maturity of Private Notes
    tendered, stating that the tender is being made thereby and guaranteeing
    that, within five New York Stock Exchange trading days after the Expiration
    Date, the Letter of Transmittal (or a facsimile thereof), together with the
    certificate(s) representing the Private Notes in proper form for transfer or
    a Book-Entry Confirmation, as the case may be, and any other documents
    required by the Letter of Transmittal, will be deposited by the Eligible
    Institution with the Exchange Agent; and
    
 
        (c) Such properly executed Letter of Transmittal (or facsimile thereof),
    as well as the certificate(s) representing all tendered Private Notes in
    proper form for transfer and all other documents required by the Letter of
    Transmittal are received by the Exchange Agent within five New York Stock
    Exchange trading days after the Expiration Date.
 
    Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Private Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
    Except as otherwise provided herein, tenders of Private Notes may be
withdrawn at any time prior to 5:00 p.m. New York City time, on the Expiration
Date.
 
    To withdraw a tender of Private Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to the Expiration Date. Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Private Notes to be withdrawn (the "Depositor"), (ii) identify the Private
Notes to be withdrawn (including the certificate number or numbers and principal
amount of such Private Notes) and (iii) be signed by the holder in the same
manner as the original signature on the Letter of Transmittal by which such
Private Notes were tendered (including any required signature guarantees). All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company in its sole discretion, whose
determination shall be final and binding on all parties. Any Private Notes so
withdrawn will be deemed not to have been validly tendered for purposes of the
Exchange Offer and no Exchange Notes will be issued with respect thereto unless
the Private Notes so withdrawn are validly retendered. Properly withdrawn
Private Notes may be retendered by following one of the procedures described
above under "The Exchange Offer--Procedures for Tendering" at any time prior to
the Expiration Date.
 
CONDITIONS
 
    Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or exchange the Exchange Notes for, any
Private Notes, and may terminate the Exchange Offer as provided herein before
the acceptance of such Private Notes, if the Exchange Offer violates applicable
law, rules or regulations or an applicable interpretation of the staff of the
Commission.
 
    If the Company determines in its reasonable discretion that any of these
conditions are not satisfied, the Company may (i) refuse to accept any Private
Notes and return all tendered Private Notes to the tendering holders, (ii)
extend the Exchange Offer and retain all Private Notes tendered prior to the
expiration of the Exchange Offer, subject, however, to the rights of holders to
withdraw such Private Notes (see "--Withdrawal of Tenders") or (iii) waive such
unsatisfied conditions with respect to the Exchange Offer and accept all
properly tendered Private Notes that have not been withdrawn. If such waiver
constitutes a material change to the Exchange Offer, the Company will promptly
disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders of the Private Notes, and the Company will
extend the Exchange Offer for a period of five to ten business days, depending
upon the significance of the waiver and the manner of disclosure to the
registered holders, if the Exchange Offer would otherwise expire during such
five to ten business day period.

TERMINATION OF CERTAIN RIGHTS
 
    All rights under the Registration Rights Agreement (including registration
rights) of holders of the Private Notes eligible to participate in the Exchange
Offer will terminate upon consummation of the Exchange Offer except with respect
to the Company's continuing obligations (i) to indemnify such holders (including
any broker-dealers) and certain parties related to such holders against certain
liabilities (including liabilities under the Securities Act), (ii) to provide,
upon the request of any holder of a transfer-restricted Private Note, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Private Notes pursuant to Rule 144A, (iii) to use its
best efforts to keep the Registration Statement effective to the extent
necessary to ensure that it is available for resales of transfer-restricted
Private Notes by broker-dealers for a period of one full year from the
Expiration Date and (iv) to provide copies of the latest version of the
Prospectus to broker-dealers upon their request for one full year after the
Expiration Date.
 
LIQUIDATED DAMAGES
 
    In the event of a Registration Default (as defined in the Private Note),
Special Interest will accrue with respect to the first 90-day period immediately
following the occurrence of such Registration Default (from and including the
date on which such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured), at a rate of 0.50% per annum.
The rate at which Special Interest accrues will increase by 0.25% per annum at
the end of each subsequent 90-day period until all Registration Defaults have
been cured, but in no event shall such rate exceed 2.00% per annum in the
aggregate regardless of the number of Registration Defaults. Following the cure
of all Registration Defaults, the accrual of all Special Interest will cease.
The filing and effectiveness of the Registration Statement of which this
Prospectus is a part and the consummation of the Exchange Offer will eliminate
all rights of the holders of Private Notes eligible to participate in the
Exchange Offer to receive damages that would have been payable if such actions
had not occurred.
 
    Holders of Transfer Restricted Securities (as defined below) will be
required to make certain representations to the Company (as described in the
Registration Rights Agreement) in order to participate in the Exchange Offer and
will be required to deliver information to be used in connection with the Shelf
Registration Statement (as defined in the Registration Rights Agreement) and to
provide comments on the Shelf Registration Statement within the time periods set
forth in the Registration Rights Agreement in order to have their Transfer
Restricted Securities included in the Shelf Registration Agreement and benefit
from the provisions regarding Special Interest set forth above. Transfer
Restricted Securities shall mean each Private Note until (i) the date on which
such Private Note has been exchanged for an Exchange Note in the Exchange Offer,
(ii) following the exchange by a broker-dealer in the Exchange Offer of such
Private Note for one or more Exchange Notes, the date on which such Exchange
Notes are sold to a purchaser who receives from such broker-dealer on or prior
to the date of such sale a copy of this Prospectus, (iii) the date on which such
Private Note has been effectively registered under the Securities Act and
disposed of in accordance with the Shelf Registration Statement or (iv) the date
on which such Private Note is distributed to the public pursuant to Rule 144(k)
under the Securities Act.

FEES AND EXPENSES
 
    The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telephone or in person by officers and regular
employees of the Company and its affiliates.
 
    The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith.
 
    The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company and are estimated in the aggregate to be approximately
$175,000. Such expenses include registration fees, fees and expenses of the
Exchange Agent and the Trustee, accounting and legal fees and printing costs,
among others.
 
    The Company will pay all transfer taxes, if any, applicable to the exchange
of Private Notes pursuant to the Exchange Offer. If, however, a transfer tax is
imposed for any reason other than the exchange of the Private Notes pursuant to
the Exchange Offer, then the amount of any such transfer taxes (whether imposed
on the registered holder or any other persons) will be payable by the tendering
holder. If satisfactory evidence of payment of such taxes or exemption therefrom
is not submitted with the Letter of Transmittal, the amount of such transfer
taxes will be billed directly to such tendering holder.
 
CONSEQUENCE OF FAILURES TO EXCHANGE
 
    Participation in the Exchange Offer is voluntary. Holders of the Private
Notes are urged to consult their financial and tax advisors in making their own
decisions on what action to take.
 
    The Private Notes that are not exchanged for the Exchange Notes pursuant to
the Exchange Offer will remain restricted securities. Accordingly, such Private
Notes may be resold only (i) to a person whom the seller reasonably believes is
a QIB in a transaction meeting the requirements of Rule 144A, (ii) in a
transaction meeting the requirements of Rule 144 under the Securities Act, (iii)
outside the United States to a foreign person in a transaction meeting the
requirements of Rule 904 under the Securities Act, (iv) in accordance with
another exemption from the registration requirements of the Securities Act (and
based upon an opinion of counsel if the Company so requests), (v) to the Company
or (vi) pursuant to an effective registration statement and, in each case, in
accordance with any applicable securities laws of any state of the United States
or any other applicable jurisdiction.
 
ACCOUNTING TREATMENT
 
    For accounting purposes, the Company will recognize no gain or loss as a
result of the Exchange Offer. The expenses of the Exchange Offer will be
amortized over the term of the Exchange Notes.

                                USE OF PROCEEDS
 
    This Exchange Offer is intended to satisfy certain of the Company's
obligations under the Registration Rights Agreement. The Company will not
receive any cash proceeds from the issuance of the Exchange Notes offered in the
Exchange Offer. In consideration for issuing the Exchange Notes as contemplated
in this Prospectus, the Company will receive in exchange Private Notes in like
principal amount at maturity, the form and terms of the Exchange Notes are the
same as the form and terms of the Private Notes except that (i) the exchange
will have been registered under the Securities Act, and, therefore, the Exchange
Notes will not bear legends restricting the transfer thereof and (ii) holders of
the Exchange Notes will not be entitled to certain rights of holders of the
Private Notes under the Registration Rights Agreement, which rights will
terminate upon the consummation of the Exchange Offer. The Private Notes
surrendered in exchange for Private Notes will be retired and canceled and
cannot be reissued. Accordingly, issuance of the Exchange Notes will not result
in any increase in the indebtedness of the Company.
 
    The net proceeds to the Company from the Private Note Offering and the sale
of equity pursuant to the Additional Equity Investment were approximately $260.7
million after deducting the discount and commissions and other expenses related
to the Private Note Offering and the Additional Equity Investment.
 
    The Company intends to use the net proceeds of the Private Note Offering and
the Additional Equity Investment as follows: (i) to fund development and
construction costs of the Company's networks, including the costs of purchasing
or leasing communications equipment, computers, switches, facilities and related
support infrastructure; (ii) for the purchase and installation of equipment to
be located at customers' premises; (iii) for rights-of-way or access payments;
(iv) to fund the development of support, control and management information
systems; (v) to fund product development; and (vi) for working capital and other
general corporate purposes, including funding operating deficits and net losses.
The Company currently intends to allocate substantial proceeds to each of the
foregoing categories. However, the precise allocation of funds among these uses
will depend on future technological, regulatory and other developments in or
affecting the Company's business, the competitive climate in which it operates
and the emergence of future opportunities.
 
    As part of its business strategy, the Company intends to continue to
evaluate potential acquisitions, joint ventures and strategic alliances that
complement the Company's business. A portion of the proceeds of the Private Note
Offering and the Additional Equity Investment, as well as additional sources of
capital such as credit facilities and other borrowings, and additional debt and
equity issuances, may be used to fund any such acquisitions, joint ventures and
strategic alliances. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
    Because of the number and variability of factors that determine the
Company's use of the net proceeds of the Private Note Offering and the
Additional Equity Investment, management will retain a significant amount of
discretion over the application of the net proceeds. There can be no assurance
that such applications will not vary substantially from the Company's current
intention. Pending such utilization, the Company has and will continue to invest
the net proceeds of the Private Note Offering and the Additional Equity
Investment in short-term investment grade securities.

    The selected consolidated financial data presented below for the period from
September 1, 1993 (inception) to September 30, 1993, for the years ended
September 30, 1994, 1995, 1996 and 1997, for the period from September 1, 1993
(inception) to September 30, 1997, and as of September 30, 1997 have been
derived from the audited consolidated financial statements of the Company. The
selected consolidated financial data presented below as of June 30, 1998 and for
the nine month periods ended June 30, 1997 and 1998 and the period from
September 1, 1993 (inception) to June 30, 1998 have been derived from the
unaudited consolidated financial statements of the Company. In the opinion of
management, the unaudited financial statements have been prepared on the same
basis as the audited financial statements and include all adjustments, which
consist only of normal recurring adjustments, necessary for a fair presentation
of the financial position and the results of operations for these periods. These
financial statements have been prepared in accordance with accounting principles
generally accepted in the United States which may differ in certain aspects from
accounting principles generally accepted in certain of the jurisdictions in
which the Exchange Notes are being offered. Operating results for the nine month
period ended June 30, 1998 are not necessarily indicative of the results that
may be expected for the full year ending September 30, 1998. The data below
should be read in conjunction with "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and the Consolidated Financial
Statements of the Company and notes thereto.

(1) EBITDA represents earnings before interest, income taxes, depreciation and
    amortization. EBITDA is not a measurement of financial performance under
    generally accepted accounting principles, is not intended to represent cash
    flow from operations, and should not be considered as an alternative to net
    loss as an indicator of the Company's operating performance or to cash flows
    as a measure of liquidity. The Company believes that EBITDA is widely used
    by analysts, investors and other interested parties in the
    telecommunications industry. The Company's computation of EBITDA may not be
    comparable to similarly titled measures for other companies.
    
 
   
(2) For purposes of calculating the ratio of earnings to fixed charges, earnings
    is defined as net loss plus fixed charges (other than capitalized interest).
    Fixed charges consist of interest and amortization of debt discount and debt
    issuance costs, whether expensed or capitalized, and that portion of rental
    expense deemed to represent interest (estimated to be one-third of such
    expense). For the periods presented, earnings were insufficient to cover
    fixed charges by the amounts disclosed.

OVERVIEW
 
    The Company is a facilities-based ICP which is deploying networks to provide
telecommunications solutions to businesses in clustered, demographically
attractive second tier markets. The Company offers "one-stop shopping" for a
broad array of telecommunications services, including local and long distance
telephone service, high speed Internet access, data connectivity, LAN
connectivity, web hosting, video communications and system integration services.
Within its target markets, the Company has segmented the potential business
customer base and tailored its service offerings, sales and marketing approach
and network development to provide service in a cost effective manner to each
segment. The Company believes its regional approach allows it to best leverage
its network facilities, sales force, customer support staff and brand identity.
The Company's first network clusters will serve the second tier markets
surrounding metropolitan Los Angeles, including Orange County and the San
Gabriel Valley and South Bay areas of Los Angeles County. The Company intends to
selectively expand its reach into other regional markets, both within and
outside of California.
 
    FirstWorld has designed and implemented an advanced and reliable fiber-based
network. Central to the Company's network design is its state-of-the art
integrated voice and data central office service platform, which allows the
Company to integrate third-party systems and the Company's operational support
systems into a unified network. The Company has designed business processes to
simplify provisioning, billing, network management and customer service and has
incorporated operational support systems that implement such processes into its
networks. Among other things, the Company has designed its systems to maximize
operational efficiency by allowing the Company to provide
single-point-of-contact customer service and by facilitating electronic
exchanges of information with the ILEC when possible.
 
    The Company is a development stage company and to date has experienced
significant operating and net losses and negative cash flow from operations and
expects that operating and net losses and negative operating cash flow will
continue for at least the next several years and will increase significantly as
the Company implements its growth strategy of expanding into other cities. See
"Risk Factors--Limited History of Operations; Negative Cash Flow and Operating
Losses," "--Substantial Leverage; Ability to Service Indebtedness" and
"--Significant Capital Requirements." The Company expects to achieve positive
operating margins over time by increasing the number of customers and increasing
the products and services it can provide its customers. The Company expects that
operating and net losses and negative operating cash flow will increase
significantly as the Company implements its growth strategy of expanding its
operations. See "--Liquidity and Capital Resources."
 
    REVENUE
 
    The Company currently offers a broad array of telecommunications services,
including local and long distance telephone service, high speed Internet access,
data connectivity, LAN connectivity, web hosting, video communications and
system integration services. The Company intends to generate near term
 
                                       35
<PAGE>
   
revenue from basic services currently provided by ILECs and IXCs, including
local, long distance and other voice services, dedicated access lines and
commercial Internet access, as well as from advanced network services provided
to select customers. The Company believes that it is positioned to generate
additional revenue by providing advanced network services to a broader market as
the demand for such services grows. The Company currently prices services, such
as local and long distance services, which are directly comparable to its
competitors' offerings below prevailing market rates to build market share. The
Company believes that its initial networks in Orange County and the San Gabriel
Valley and South Bay areas of Los Angeles County will allow it to provide
services to a market that includes approximately one million commercial access
lines.
    
 
    The Company employs a market segmentation strategy, which involves tailoring
service offerings, sales and marketing techniques and network deployment to meet
the different needs of prime commercial, basic commercial, wholesale transport
and wholesale functionality customers. For prime commercial customers
(businesses with sophisticated communications needs), the Company utilizes a
consultative selling approach that involves a systematic assessment of each
customer's telephony, Internet, data communications and video applications
needs. For basic commercial customers (businesses with primarily voice and
Internet needs), the Company uses direct mail, telemarketing and advertising and
offers standardized product bundles consisting of local and long distance
telephony and high speed Internet access. The Company also offers use of its
network elements and central office functionality on a wholesale basis to other
local exchange carriers, including CLECs, IXCs, ISPs and other communications
providers.
 
    COSTS AND EXPENSES
 
   
    NETWORK DEVELOPMENT AND OPERATIONS.  As the Company continues to operate and
maintain its existing network and deploy additional networks, it will incur
network development and operations expenses related to network central office
operations and customer service, including salaries of the employees, real
estate leases for central offices, access offices, co-location and other sites,
costs to interconnect and terminate traffic with other network providers and
network design, planning and internal project management costs.
    
 
    The Company has leveraged its substantial internal expertise with respect to
engineering, network creation and business processes to design and construct a
network architecture that it believes will result in enhanced product offerings
and enable the Company to improve scalability, reduce operating costs and
improve network profitability.
 
   
    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses are expected to consist primarily of product marketing, sales staff and
sales support expenses, consulting fees related to ongoing regional expansion
studies, general management and administrative overhead expenses and office
leases.
    
 
    Management has developed the Company's business processes with respect to
customer service, billing, provisioning and network management systems based on
extensive industry and engineering expertise within the Company. The Company has
developed operational support systems, incorporated systems from existing
external sources and retained third parties to produce systems meeting the
Company's specifications to create integrated systems that implement the
Company's business processes. As with its network architecture described above,
the Company believes that its systems exhibit a high degree of scalability to
support network growth, flexibility to support product or technical innovation,
increased reliability and reduced operational cost.
 
    The Company uses different sales channels to target customers within the
four market segments identified by the Company. The Company uses direct sales
efforts in a consultative selling approach with prime commercial customers,
direct sales efforts for wholesale customers and more economical methods such as
direct mail and telemarketing to target basic commercial customers. The Company
is in the process of significantly expanding its sales and marketing staff.
 
                                       36
<PAGE>
    CAPITAL EXPENDITURES.  The Company's principal capital expenditure
requirements involve the installation of network infrastructure, which mainly
relates to the installation of fiber optic loops in fiber clusters and the
installation of CLE.
 
    The Company employs a demand-driven approach to network construction. This
approach is intended to minimize deployment of capital not associated with
customer revenue and maximize flexibility to serve the higher margin data market
as demand for high speed data communications services grows. In the deployment
of infrastructure, the Company markets its services to a geographically targeted
cluster of businesses before committing to build a complete fiber-to-the-curb
ring. The Company connects customers to its networks through direct fiber
connections, DSL technology or unbundled network elements licensed from the ILEC
depending on the most cost-effective connection that will support the bundle of
services required by the customer.
 
    For customers served by fiber, the Company generally requires a contract
specifying minimum product usage, pricing and term of service, among other
items. The Company's objective is to reduce the risk associated with capital
deployment of CLE. The Company's contracts generally have terms of one to three
years, depending upon total revenue, services provided and discount or
promotional package.
 
RESULTS OF OPERATIONS
 
   
    NINE MONTHS ENDED JUNE 30, 1998 COMPARED WITH THE NINE MONTHS ENDED JUNE 30,
     1997
    
 
   
    Service revenue increased from zero for the nine-month period ended June 30,
1997 to $649,000 for the nine-month period ended June 30, 1998. The increase
reflects the Company's first three full quarters of network operations. Prior to
the commencement of operations of the Company's Orange County network, the
Company's service revenue consisted principally of reimbursable engineering,
design and construction costs associated with the design of fiber optic
communications networks on a contract basis for the cities of Lakeland, Florida
and Santa Clara, California. Other revenue represents royalties from the license
of the Company's patent for fiber optic connectors. Royalty revenue decreased
from $114,000 for the nine-month period ended June 30, 1997 to $10,000 for the
nine-month period ended June 30, 1998, a decrease of $104,000 or approximately
91%. Going forward, the Company expects that revenue from sales of telephony and
data products and services in Orange County and in other areas targeted for
network construction will account for substantially all of the Company's total
revenue. The Company does not expect that royalty revenue from the patent
license will constitute a significant portion of total revenue in the future as
the Company expands its initial network rollout.
    
 
   
    Network development and operations expenses increased from $3,186,000 for
the nine-month period ended June 30, 1997 to $5,497,000 for the nine-month
period ended June 30, 1998, an increase of $2,311,000 or approximately 73%. This
increase is principally comprised of increased personnel costs in the operations
and engineering groups and increased operating costs for the Company's Anaheim
central office.
    
 
   
    Selling, general and administrative expenses increased from $2,806,000 for
the nine-month period ended June 30, 1997 to $4,756,000 for the nine-month
period ended June 30, 1998, an increase of $1,950,000 or approximately 70%. In
December 1997, the Company entered into agreements with each of Corporate
Managers, LLC, an affiliate of Spectra 3, and Enron to provide management
consulting services. In March 1998, the agreement with Corporate Managers, LLC
was amended. Fees associated with these agreements are $280,000 per quarter and
payable in arrears. During the period ended June 30, 1998, the Company paid fees
totaling $560,000 under these agreements. Also in March 1998, the Company
engaged an executive recruiting firm to conduct an executive search assignment
for the Chief Executive Officer position. Fees associated with this agreement
totaled approximately $167,000 for the nine-month period ended June 30, 1998.
The remaining increase was principally due to additional marketing, sales and
administrative personnel and an increase in administration expenses related to
rent, liability insurance, telephone and consulting expenses.
    
 
                                       37
<PAGE>
   
    Depreciation and amortization expenses increased from $393,000 for the
nine-month period ended June 30, 1997 to $1,841,000 for the nine-month period
ended June 30, 1998, an increase of $1,448,000 or approximately 369%. This
increase primarily relates to the Nortel DMS 500 switch and other equipment in
the Anaheim central office and the built and leased elements of the Company's
fiber optic network and office and other equipment associated with the Company's
general operations.
    
 
   
    Interest expense increased from $242,000 for the nine-month period ended
June 30, 1997 to $11,072,000 for the nine-month period ended June 30, 1998, an
increase of $10,830,000 or approximately 4,479%. $8,212,000 of the increase
relates to the accretion of the Notes. $915,000 of the increase relates to
interest expense associated with the Company's capital lease arrangements with
the City of Anaheim. $513,000 of the increase relates to interest expense under
the Company's Credit Facility; $635,000 of the increase relates to amortization
of deferred loan costs associated with the Company's Credit Facility. The
remaining portion relates to other short-term loans and interest expense
associated with the Company's capitalized central office building lease and
other capital equipment leases.
    
 
   
    Interest income increased from $143,000 for the nine-month period ended June
30, 1997 to $3,247,000 for the nine-month period ended June 30, 1998, an
increase of $3,104,000 or approximately 2,164%. The increase is a result of the
availability of additional funds from the sale of the Notes for investments in
Marketable Securities and cash equivalents. Marketable Securities consist of
commercial paper with original maturities of beyond three months but less than
six months. The Company has classified its Marketable Securities as "held to
maturity," as management has the intent and ability to hold these securities to
maturity. The fair value of the Company's Marketable Securities approximates the
carrying value.
    
 
    YEAR ENDED SEPTEMBER 30, 1997 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1996
 
    Service revenue decreased from $279,000 in 1996 to $75,000 in 1997, a
decrease of $204,000. This decrease reflects the Company's transition from
performing engineering and consulting contracts to developing its own
telecommunications network. Prior to the commencement of operations of the
Company's Orange County network, the Company's service revenue consisted
principally of reimbursable engineering, design and construction costs
associated with the design of fiber optic communications networks on a contract
basis for the cities of Lakeland, Florida and Santa Clara, California. These
engineering contracts were substantially complete in 1996, with only $55,000 of
engineering and consulting revenue recognized in 1997, and the Company stopped
bidding on new engineering contracts in order to focus on design and
construction of its Orange County network. The Company's first customer for its
Orange County network was brought on line in August 1997, and the Company
recognized service revenue from its network operations of $20,000 in fiscal
1997. Other revenue represents royalties from the license of the Company's
patent for fiber optic connectors. Royalty revenue increased from $75,000 in
1996 to $96,000 in 1997. Going forward, the Company expects that revenue from
sales of telephony and data products and services in Orange County and in other
areas targeted for network construction will account for substantially all of
the Company's total revenue. The Company does not expect that royalty revenue
from the patent license will constitute a significant portion of total revenue
in the future as the Company expands its Orange County network.
 
    Network development and operations expenses increased from $1,708,000 in
1996 to $3,170,000 in 1997, an increase of $1,462,000 or 86%. This increase is
principally comprised of increased personnel costs in the operations and
engineering groups, increased operating costs for the Company's Anaheim central
office and costs for equipment needed to finish a 1996 engineering project.
 
    Selling, general and administrative expenses increased from $2,409,000 in
1996 to $4,725,000 in 1997, an increase of $2,316,000 or 96%. This increase was
principally due to increased personnel costs of sales and marketing and
administrative personnel and an increase in administration expense related to
rent, insurance and telephone.
 
                                       38
<PAGE>
    Depreciation and amortization expenses increased from $75,000 in 1996 to
$501,000 in 1997, an increase of $426,000. This increase consists principally of
depreciation related to the Anaheim central office and built and leased elements
of the fiber optic network in Anaheim and depreciation related to office and
other equipment associated with the Company's general operations.
 
    Interest expense increased from $27,000 in 1996 to $1,372,000 in 1997.
$997,000 of the increase relates to interest expense associated with the
Company's capital lease arrangements with the City of Anaheim. See
"Business--Agreements with the City of Anaheim and The Irvine Company" and Note
8 of Notes to Consolidated Financial Statements. The other principal reasons for
the increase are interest expense under the Credit Facility and other short-term
loans and interest expense associated with the Company's capitalized central
office building lease and other capital equipment leases. See "--Liquidity and
Capital Resources."
 
    Interest income increased from $9,000 to $149,000 in 1997. The increase of
$140,000 is a result of an increase in funds available for short-term investment
as a result of funds raised from sales of preferred stock in January 1997.
 
    YEAR ENDED SEPTEMBER 30, 1996 COMPARED WITH YEAR ENDED SEPTEMBER 30, 1995
 
    Service revenue increased from $57,000 in 1995 to $279,000 in 1996, an
increase of $222,000. This increase relates to the engineering contracts with
the cities of Lakeland, Florida and Santa Clara, California, for which revenue
was first recognized in late 1995, with a majority of the revenue being
generated in 1996. Other revenue represents royalties from the license of the
Company's patent for fiber optic connectors.
 
    Network development and operations expenses increased from $188,000 in 1995
to $1,708,000 in 1996, an increase of $1,520,000. The increase is principally
comprised of increased personnel costs of the engineering and operations group,
increased consulting costs associated with the start-up of the Company's Anaheim
central office and network, legal fees relating to the agreements with the City
of Anaheim and regulatory issues, and general increases in operations expenses,
including rent, travel, supplies and telephone.
 
    Selling, general and administrative expenses increased from $740,000 in 1995
to $2,409,000 in 1996, an increase of $1,669,000. This increase was principally
due to increased personnel costs in sales, marketing, administration and
executive personnel, an increase in consultant expenses, including political,
public relations and general business consultants, increased legal fees and an
increase of general business and administrative expenses.
 
    Depreciation and amortization expenses increased from $39,000 in 1995 to
$75,000 in 1996, an increase of $36,000. This increase primarily consists of
depreciation related to office and other equipment associated with the Company's
general operations and depreciation related to network assets.
 
    Interest expense decreased from $38,000 in 1995 to $27,000 in 1996, a
decrease of $11,000. Interest in 1996 related to interest on capital equipment
leases. Interest in 1995 related to capital lease interest and expense incurred
on notes payable prior to their conversion into preferred stock.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    The telecommunications service business is a capital intensive business. The
Company's existing operations have required and will continue to require
substantial capital investment for the installation of fiber, electronics and
related equipment in order to provide switched services in the Company's
networks and the funding of operating losses during the start-up phase of each
market. In addition, the Company's strategic plan calls for expansion into
additional market areas. Such expansion will require significant additional
capital for the design, development and construction of new networks and the
funding of operating losses during the start-up phase of each market. The
Company used $10,754,000 in cash for
    
 
                                       39
<PAGE>
   
operating activities for the nine-month period ended June 30, 1998, compared to
$5,783,000 for the nine-month period ended June 30, 1997. The increase was
primarily due to an increase in the Company's activities associated with the
development and initiation of switched local services in the City of Anaheim.
The Company invested an additional $12,311,000 of cash in property and equipment
for the nine-month period ended June 30, 1998, compared to $5,918,000 for the
nine-month period ended June 30, 1997. The Company has funded substantially all
of these expenditures through the private sale of equity securities, capital
leases, and short and long-term debt financing.
    
 
   
    From its inception through June 30, 1998, the Company raised approximately
$67 million from the private sale of stock. On December 30, 1997, the Company
consummated a private placement of equity securities to Spectra 3 and Enron.
Aggregate proceeds from this offering, exclusive of the conversion of the bridge
notes, totaled approximately $26,330,000, net of offering commissions and
certain other advisory fees, and were received on January 6, 1998. See "Certain
Transactions." The Company used $16.9 million of the net proceeds to repay
amounts outstanding under the Credit Facility and other short-term debt. On
April 13, 1998, the Company completed the Private Note Offering and the
Additional Equity Investment. In the Private Note Offering, the Company sold
470,000 units consisting of the Private Notes and warrants to purchase an
aggregate of 3,713,094 shares of the Company's Series B Common Stock. In the
Additional Equity Investment, Spectra 3 and Enron invested $20 million to
purchase shares of Series B Common Stock at $3.00 per share and warrants to
purchase shares of Series B Common Stock at $3.00 per share. The aggregate net
proceeds of the Private Note Offering and the Additional Equity Investment were
$260.7 million.
    
 
   
    The substantial capital investment required to initiate the Company's
services and the funding of the Company's initial operations has resulted in
negative cash flow since the Company's inception. This negative cash flow is the
result of the requirement to construct the Company's central office in Anaheim
and the construction of fiber-to-the-curb clusters in anticipation of connecting
revenue generating customers. The Company expects to continue to experience
negative cash flow for the foreseeable future due to expansion activities
associated with the development of the Company's markets. There can be no
assurance that the Company will attain break-even cash flow in subsequent
periods. Until sufficient cash flow is generated, the Company will be required
to utilize its current and future capital resources to meet its cash flow
requirements and may be required to issue additional debt and/or equity
securities.
    
 
   
    The Company expects that its available cash will be sufficient to fund its
capital plan and operations through the buildout of its proposed networks in
Orange County and the San Gabriel Valley and South Bay areas of Los Angeles
County, which are expected to be substantially complete by the end of 1999. As
the Company pursues expansion of its network to additional areas or if the
Company's available cash resources are not sufficient to fund all of the
Company's operating expenses and capital expenditures, the Company will require
additional capital. In addition, depending on market conditions, the Company may
determine to raise additional capital from time to time. The Company may obtain
additional funding through the public or private sale of debt and/or equity
securities or through securing a bank credit facility.

                                    BUSINESS
 
    The Company is a facilities-based ICP which is deploying networks to provide
telecommunications solutions to business customers in clustered, demographically
attractive second tier markets. The Company offers "one-stop shopping" for a
broad array of telecommunications services, including local and long distance
telephone service, high speed Internet access, data connectivity, LAN
connectivity, web hosting, video communications and system integration services.
Within its target markets, the Company has segmented the potential business
customer base and tailors its service offerings, sales and marketing approach
and network development to provide service in a cost-effective manner to each
segment. The Company believes its regional approach allows it to best leverage
its network facilities, sales force, customer support staff and brand identity.
The Company's first network clusters will serve second tier markets surrounding
metropolitan Los Angeles, including Orange County and the San Gabriel Valley and
South Bay areas of Los Angeles County. The Company intends to selectively expand
its reach into other regional markets, both within and outside of California.
 
   
    The Company's largest stockholders are entities controlled by Donald L.
Sturm, former Vice Chairman of Peter Kiewit Sons' Inc., the founder of MFS
Communications, and Enron, a subsidiary of Enron Corp., one of the world's
leading integrated natural gas and electricity companies. To date, these
stockholders have provided $55 million of the $67 million in equity capital
received by the Company. The Company and Enron have an informal collaborative
relationship to jointly market telecommunications and utility services which the
Company believes can provide it with access to new markets, sales synergies and
product development opportunities.
    
 
   
    The Company began network operations in August 1997 and began providing
services to commercial customers in November 1997. As of July 31, 1998, the
Company had approximately 100 commercial customers under contract. The City of
Anaheim, the Company's most significant customer, relies on the Company to
supply local dialtone, long distance, dedicated facilities and Internet service
to substantially all of its municipal facilities.
    
 
    FirstWorld has designed and implemented an advanced and reliable fiber-based
network. Central to the Company's network design is its state-of-the-art
integrated voice and data central office service platform, which allows the
Company to integrate third-party systems and the Company's operational support
systems into a unified network. The Company believes its networks also are
capable of providing server-based applications, such as virtual LANs and
e-commerce, and will be compatible with voice over Internet technologies as such
technologies are refined in the industry. The Company has designed business
processes to simplify provisioning, billing, network management and customer
service and has incorporated operational support systems that implement such
processes into its networks. Among other things, the Company has designed its
systems to allow the Company to provide single-point-of-contact customer service
and to facilitate electronic exchanges of information with the ILEC when
possible.
 
    The Company employs a demand-driven approach to network construction. This
approach is intended to minimize deployment of capital not associated with
customer revenues and maximize flexibility to serve the higher margin data
market as demand for high speed data communication services grows. The Company
connects customers to its networks through direct fiber connections, DSL or
unbundled network elements licensed from the ILEC, depending on the most
cost-effective connection that will support the bundle of services provided to
the customer. The Company generally requires customers that are connected by
fiber to sign long-term contracts to offset the cost of capital deployed.
 
   
    Although the Company does not own all of the facilities it uses to serve its
customers, it does own key components of such facilities. FirstWorld owns all of
its switching, transport and central monitoring equipment located in the Anaheim
central office, fiber optic clusters used to link customers to the fiber
backbone which it partially owns and partially leases from other entities and,
for customers connected to the Company's network via a direct fiber connection,
the fiber connections and CLE necessary to deliver requested services to such
customers. The Company also owns switching and transport equipment co-located in
other carriers' facilities.
    
 
                                       41
<PAGE>
    The Company believes that the market segments within its target markets have
different customer buying patterns, are subject to different competitive factors
and can best be served by different sales and marketing initiatives. The
following chart outlines the principal components of this approach:

</TABLE>
 
    For prime commercial customers (businesses with sophisticated communications
needs), the Company utilizes a consultative selling approach that involves a
systematic assessment of each customer's telephony, Internet, data
communications and video applications needs. For basic commercial customers
(businesses with primarily voice and Internet needs), the Company uses direct
mail, telemarketing and advertising and offers standardized product bundles
consisting of local and long distance telephony and high speed Internet access.
The Company also offers use of its network capabilities on a wholesale basis to
other local exchange carriers, including CLECs, IXCs, ISPs and other
communications providers.
 
    The Company uses strategic relationships with municipalities, property
developers, service providers and others that provide the Company with brand
identity, physical assets, new products or technologies, joint marketing
synergies or other support. The Company believes its existing relationships with
the City of Anaheim, The Irvine Company and Enron provide the Company with
significant advantages in marketing and network deployment.
 
    The Company intends to generate near-term revenue from basic services
currently provided by ILECs and IXCs, including local, long distance and other
voice services, dedicated access lines and commercial Internet access, as well
as from advanced network services provided to select customers. The Company
believes that it is positioned to generate additional revenue by providing
advanced network services to a broader market as the demand for such services
grows.
 
   
    The Company's strategy and network architecture are designed to exploit a
number of trends reshaping the $190 billion telecommunications industry,
including (i) increasing customer demand for high speed, broadband services,
such as the Internet, data networks and video conferencing, (ii) integration of
the markets for local exchange and long distance services, (iii) decreased cost
of high bandwidth connectivity over the wide area, (iv) technical and product
innovation associated with the Internet, transmission control protocol/Internet
protocol ("TCP/IP") and voice over Internet technologies, (v) the further
development of server-based applications and (vi) the migration of existing
business processes to electronic formats.
    
 
   
CORPORATE HISTORY
    
 
   
    The Company was incorporated as a California corporation in July 1992 under
the name Sigma Link but did not commence operations until September 1993. Sigma
Link was formed as a wholly owned subsidiary of Lambda Link, a Nevada
corporation ("Lambda Link Nevada"). The Company changed its name from Sigma Link
to Lambda Link International in May 1993. In September 1993, two of the three
principal shareholders of Lambda Link Nevada (the "Separating Shareholders")
resolved a philosophical disagreement they had with the other principal
shareholder of Lambda Link Nevada (the "Remaining Shareholder") regarding the
direction that the business and operations of Lambda Link Nevada should
    
 
                                       42
<PAGE>
   
take by entering into a separation agreement (the "Restructuring").
Specifically, the Separating Shareholders wanted Lambda Link Nevada to become
the facilities based ICP that the Company is today; whereas, the Remaining
Shareholder wanted Lambda Link Nevada to continue to concentrate on engineering,
designing and installing fiber optic and cabling communications systems.
    
 
   
    In connection with the Restructuring, Lambda Link Nevada transferred its
100% ownership interest in the Company and certain other assets to the
Separating Shareholders in exchange for the stock the Separating Shareholders
held in Lambda Link Nevada. In addition, the Separating Shareholders resigned
from the board of directors of Lambda Link Nevada, agreed to change the name of
the Company and assumed certain liabilities of Lambda Link Nevada. Subsequent to
the Restructuring, the Company changed its name from Lambda Link International
to SpectraNet International and assumed the assets and liabilities of Lambda
Link Nevada that the Separating Shareholders received in the Restructuring. Both
Separating Shareholders have since left the Company.
    
 
   
    In January 1998, the Company changed its name from SpectraNet International
to FirstWorld Communications, Inc. In June 1998, the Company changed its state
of incorporation from California to Delaware.
    
 
BUSINESS STRATEGY
 
    The Company's goal is to become the premier ICP in the markets that it
serves. The Company also is seeking to achieve a high degree of market
penetration, form long-term customer relationships and establish a diversified
revenue base. The principal elements of the Company's business strategy include:
 
    TAILOR SERVICE OFFERINGS AND SALES TECHNIQUES TO MARKET SEGMENTS.  The
Company employs a market segmentation strategy, which involves tailoring service
offerings, sales and marketing techniques and network deployment to meet the
different needs of prime commercial, basic commercial, wholesale transport and
wholesale functionality customers. The Company believes these market segments
have different customer buying patterns, are subject to different competitive
factors and can best be served by different sales and marketing initiatives.
 
    DEPLOY FLEXIBLE NETWORKS TO PROVIDE VOICE AND DATA SOLUTIONS.  The Company
deploys sophisticated fiber-based networks capable of providing integrated
voice, data, Internet and video solutions. The Company has designed its
networks, including its central office service platform, to support a wide array
of telecommunications services and to be compatible with technologies still
under development in the industry, including server-based applications, such as
virtual LANs and e-commerce, and voice over Internet.
 
    PURSUE DEMAND-DRIVEN NETWORK DEPLOYMENT.  The Company utilizes a
demand-driven approach to network construction. In the deployment of
infrastructure, the Company markets its services to a geographically targeted
cluster of businesses before committing to build a complete fiber-to-the-curb
ring. In addition, the Company connects customers to its networks through direct
fiber connections, DSL or unbundled loops, depending on the product set and
anticipated revenue and margin from the customers.
 
    GAIN EFFICIENCY THROUGH REGIONAL CONCENTRATION.  The Company has adopted a
targeted geographic approach to network deployment. The Company believes the
benefits of building networks in second tier cities clustered within geographic
regions with high business densities include (i) increased market penetration
due to increased focus on management of market activities, support of sales
activities and leverage of advertising or other brand equity, (ii) enhanced
operating margin from a higher proportion of calls that both originate and
terminate on the Company's network, (iii) increased leverage of centralized
assets such as a central office or product platforms and (iv) reduced travel,
regulatory and administrative expenses.
 
    EXPLOIT INTERNAL ENGINEERING AND PRODUCT EXPERTISE.  The Company intends to
leverage its substantial internal engineering and product expertise to enhance
and expand the services it offers, decrease network
 
                                       43
<PAGE>
construction costs, achieve a high degree of scalability, reduce operating
costs, increase reliability and facilitate migration to new technologies over
time.
 
    DEVELOP STRATEGIC RELATIONSHIPS.  The Company intends to continue to develop
strategic relationships with municipalities, property developers, service
providers and others that provide the Company with brand identity, physical
assets, new products or technologies, joint marketing synergies or other
support. To date, the Company has established such relationships with the City
of Anaheim, The Irvine Company, Enron and others. The Company's agreements with
the City of Anaheim give the Company exclusive commercial rights to a 50-mile
fiber loop that serves as the backbone for the Company's Anaheim network. The
Irvine Company agreements give the Company rights to install fiber in existing
conduit within a commercial development known as the "Irvine Spectrum." While
the Company intends to establish additional strategic relationships, it also
intends to enter otherwise attractive markets without such relationships.
 
MARKET SEGMENTATION APPROACH
 
    The Company believes that the segments within its target markets have
different customer buying patterns, are subject to different competitive factors
and can best be served by different sales and marketing initiatives. The Company
tailors its voice, data, Internet and video offerings, sales and marketing
approach and network development to provide cost-effective service to prime
commercial, basic commercial, wholesale transport and wholesale functionality
customers that it targets.
 
    PRIME COMMERCIAL.  Prime commercial customers are large and medium sized
businesses that demand a range of sophisticated voice, data, Internet and video
services. Within the prime customer segment, the Company has chosen to focus on
medium-sized businesses because the Company believes that such businesses
generally are underinvested in LANs and computer systems and undersupported by
information and technology professionals. The Company also has found that
medium-sized businesses have not been aggressively targeted by the Company's
competitors, which have tended to target large and extra large businesses.
 
    The Company believes that its consultative selling approach, diverse service
offerings and customer service will offer prime customers integrated solutions
to their telecommunications and information problems. The Company believes it
adds significant value for prime customers by offering them "one-stop shopping"
for a broad array of advanced voice, video, Internet and data services.
Moreover, the Company believes its ability to diagnose prime customers' needs
through consultative sales efforts and to meet those needs through bundled
service offerings will enhance the Company's reputation for value and build
brand equity. The Company intends to connect prime customers to its networks
through fiber, DSL or unbundled loops, depending on cost effectiveness and
customer needs.
 
    BASIC COMMERCIAL.  Basic commercial customers typically are small to medium
sized businesses with minimal demand for data services. The Company believes
that it can best serve basic customers by providing service offerings limited to
dialtone and high-speed Internet access and by using telemarketing, direct mail
or affinity group marketing to reduce sales costs. In addition, the Company
believes that by offering low-cost, limited service offerings to basic
customers, it will establish relationships upon which the Company can base
future efforts to sell more advanced services. The Company intends to rely
primarily upon unbundled loops to connect basic customers to its network.
 
    WHOLESALE TRANSPORT.  The Company's wholesale sales force markets dedicated
access and other connectivity services to other service providers such as
out-of-region local exchange carriers, IXCs and other CLECs. The primary
services are DS-0, DS-1(T1), DS-3 and OC-n connectivity within the network
footprint.
 
    WHOLESALE FUNCTIONALITY.  The Company markets non-transport
functionality--including advanced switching capabilities, 24-hour network
management services, billing and customer services and Internet
 
                                       44
<PAGE>
dial-up access--to other service providers. By providing such services, the
Company can serve as a virtual central office to other service providers.
 
PRODUCTS AND SERVICES
 
    The Company currently offers a wide variety of voice and data services,
including local and long distance telephone service, dedicated/high speed access
service, application support services, video conferencing and basic information
technology services, including system integration services and transparent LAN.
The Company works with its prime commercial customers to develop integrated
bundles of services to best meet their needs. For basic commercial customers,
the Company typically offers a standardized bundle of local and long distance
telephone service and Internet access service.
 
    TELEPHONY
 
    The Company currently provides local and long distance telephone service and
a full range of other narrowband telecommunications services.
 
    LOCAL EXCHANGE.  The Company offers local exchange services, including local
dialtone, call forwarding, call waiting and voice mail.
 
    CENTREX/PBX.  The Company provides flexible solutions to customers with
multiple telephones. The Company's Centrex services provide call forwarding,
call waiting, line hunting, station conferencing, automatic call-back and call
account tracking. The Company minimizes Centrex customers' capital expenditures
by providing such services through Company-owned equipment housed at the central
office. For large customers or customers with special needs, the Company
integrates customer-owned PBX systems with analog or digital PBX trunks.
 
    LONG DISTANCE, TOLL FREE AND CALLING CARD SERVICES.  The Company provides
domestic and international long distance service, toll free services and
operator services.
 
    DEDICATED/HIGH SPEED ACCESS
 
    The Company offers transport and protocol specific services which allow
customers to connect their facilities with their regional offices, customers,
vendors or remote service providers. The Company offers a range of dedicated
access services, including DS-1 (T1) and DS-3 digital channels and optical
carrier services up to and including OC-12. The Company also implements numerous
transmission protocols, including ISDN, Asynchronous Transfer Mode ("ATM"),
frame relay, native speed Ethernet (10 Mbps) and private IP.
 
    APPLICATION SUPPORT SERVICES
 
    INTERNET.  The Company currently provides high-speed Internet access at
speeds ranging from 128Kbps to 10Mbps, allowing customers to select the access
speed that best meets their needs. The Company allows customers to choose to pay
based on a flat monthly rate or based upon the bandwidth used.
 
    VALUE-ADDED INTERNET SERVICES.  The Company augments its Internet access
services with e-mail, Web hosting, file transfer and user-on-the-road support
services.
 
    VIRTUAL PRIVATE NETWORK.  The Company offers its Internet access customers a
virtual private network service, which uses authentication and encryption
software to provide a secure means of accessing corporate information using
dial-up remote access.
 
    VIDEO CONFERENCING.  The Company currently offers video conferencing
services and tailors video quality and cost to meet customers' needs.
 
                                       45
<PAGE>
    INFORMATION TECHNOLOGY SERVICES
 
    SYSTEMS INTEGRATION, INTRANET AND SERVER-BASED PRODUCTS.  The Company offers
systems integration services, including design, implementation and support of
customer networks. The Company strives to improve functionality of customers'
LANs and reduce their expenditures on LANs by utilizing elements of the
Company's networks and central office. The Company's initial focus has been on
bandwidth management, local area/wide area integration, voice and data
integration and formation of intranets. The Company is developing and intends to
offer a managed desk-top service to allow business customers to use servers
located at the Company's central office instead of building and maintaining
their own networks.
 
    TRANSPARENT LAN.  The Company currently offers transparent LAN services that
allow customers to interconnect LANs and support corporate intranets in
metropolitan area networks ("MANs") while maintaining the functionality and, in
many cases, the speed of a LAN. In most cases, the Company provides the CLE to
make such interconnection possible. By supplying the CLE, the Company allows
customers to use the Company's services without the initial capital costs often
associated with connecting remote LANs.
 
SALES AND MARKETING
 
    Consistent with its market segmentation strategy, the Company uses different
sales channels to target customers within the four market segments identified by
the Company. The Company uses direct sales efforts and a consultative selling
approach with prime commercial customers, direct sales efforts for wholesale
transport and wholesale functionality by customers and more economical methods
such as direct mail and telemarketing to target basic commercial customers. The
Company has allocated responsibilities for such selling efforts among five
different positions within its sales force structure: strategic account manager,
account manager, wholesale account manager, inside sales representative and
building entry manager. Strategic account managers are primarily responsible for
selling a complete line of products and services to prime customers in their
assigned territories. Account managers are responsible for selling pre-set
product bundles or single product solutions to basic customers, usually in
conjunction with the Company's direct mail and telemarketing efforts. Wholesale
account managers sell dedicated transport facilities, among other services, to
wholesale customers. Inside sales representatives are responsible for
telemarketing to potential customers on an ongoing basis to create appointments
for strategic account managers and account managers and assisting with sales
proposals. The Company's building entry manager is responsible for establishing
relationships with property owners and building managers to gain introduction to
their tenants.
 
    DIRECT SALES
 
    The Company uses direct sales efforts to make retail sales to prime
commercial customers and to make wholesale sales of transport and central office
functionality to large businesses, IXCs and other CLECs.
 
    PRIME COMMERCIAL.  The Company bases its direct sales efforts to prime
commercial customers on a consultative selling approach, which involves a
systematic assessment of customers' telephony usage, their satisfaction with
their existing LANs, if any, and their general communications needs. Strategic
account managers work closely with customers and the Company's own systems
engineers to develop and implement integrated telecommunications solutions. The
Company attempts to position itself as a long-term business partner able to
solve customers' problems by providing access to current and emerging
technologies through the Company's fiber-based networks. The Company believes
that this process results in the sale of value-added products in addition to
commodity-like services such as local and long distance services. Moreover, the
Company believes that this approach ultimately reduces customer turnover and
differs from the approach adopted by many of the Company's competitors whose
sales are based primarily on price discounting of basic dialtone services. The
Company believes that its consultative sales approach
 
                                       46
<PAGE>
will be particularly successful with respect to sales of the Company's
value-added Internet and transparent LAN services.
 
    WHOLESALE TRANSPORT AND WHOLESALE FUNCTIONALITY.  The Company's wholesale
account managers offer wholesale customers, such as large businesses, IXCs and
CLECs, a variety of services ranging from dedicated access to complete local
service. Such sales allow the Company to earn incremental revenue while limiting
the associated sales and marketing expenses. The Company's wholesale sales
objective is to utilize third party sales channels and existing customer
relationships.
 
    DIRECT MARKETING
 
    The Company uses direct mail and telemarketing to sell the Company's
services to basic customers and to generate leads for sales to prime customers.
Account managers build upon such marketing efforts to close sales to basic
customers. The Company typically offers basic customers a bundle of standard
services at a competitive price. For example, the Company recently has offered
basic customers one free year of Internet access service for entering into
two-year contracts for local and long distance services. The Company believes
that when it gains a sale through such methods, it not only generates revenue
from the new customer but also establishes a relationship upon which the Company
may base future efforts to sell higher margin applications.
 
    MARKETING SUPPORT AND COMMUNICATIONS POLICY
 
    The Company supports its direct sales and marketing efforts through the use
of targeted direct mail, regional advertising and its Internet web page. The
Company targets businesses for direct mail efforts through careful demographic
analyses. The Company classifies and prioritizes customers on the basis of their
standard industry classification ("SIC") codes, estimates of their
telecommunications spending and their number of employees. The Company then uses
databases to identify businesses' addresses and decision makers and mapping
tools to pinpoint their locations. By targeting customers in this way, the
Company believes that it can use direct mail in a cost-effective manner to
promote understanding of the Company and its services and to stimulate qualified
leads for the Company's retail sales force. The Company augments its direct mail
efforts through the use of regional advertising aimed at the business community.
Such advertising is designed to create a FirstWorld brand "umbrella" that
reinforces retail sales efforts by generating additional leads, establishing
brand awareness and differentiating the Company from its competitors. The
Company also uses advertising to support the launch of new services as they are
introduced to the marketplace.
 
    CO-MARKETING RELATIONSHIPS
 
    The Company seeks to establish co-marketing arrangements with the
municipalities, property developers and service providers with which it
establishes strategic relationships. The Company expects these co-marketing
relationships to take several different forms, depending on market opportunity.
For example, the Company works with the City of Anaheim's economic development
group to promote the presence of the Company's advanced network to attract new
businesses to the area. The Company intends to work with additional
municipalities to position the Company as the premier ICP to new businesses in
such cities. Similarly, The Irvine Company markets the Company's advanced
network services as an amenity available to tenants. In addition, the Company
and Enron have worked together to offer bundles of telecommunications and
utility services to municipalities and property developers.
 
   
    As of July 31, 1998, the Company employed 53 persons in sales and marketing.
The Company is in the process of significantly expanding its sales and marketing
staff but intends to continue to be selective in its recruiting, requiring
prospective salespeople to have demonstrated success in telecommunications or
data communications sales. The Company's sales operations are conducted from its
headquarters in San Diego, California and its central office in Anaheim,
California.

CUSTOMER RELATIONSHIPS
 
    The Company's goal is to become the premier ICP in the areas it serves, and
to create service offerings that appeal to customers of varying sizes and in a
variety of industries. Management believes that the customer's service purchase
decision is based primarily on the strength of the value proposition offered,
customer service and support, and price of directly comparable service. The
Company currently prices services which are directly comparable to its
competitors' offerings below prevailing market rates to build market share.
 
    For customers served by fiber, the Company generally requires a contract
specifying minimum product usage, pricing and term of service, among other
items. The Company's objective is to reduce the risk associated with capital
deployment of customer located equipment. The Company's contracts generally have
terms of one to three years, depending on total revenue commitment, services
provided and discount or promotional package.
 
   
    The Company commenced network operations in August 1997 when it brought the
City of Anaheim on line. The Company began providing services to commercial
customers in November 1997, has signed contracts with approximately 100
commercial customers as of July 31, 1998 and has been successful in selling
multiple products including voice and data applications to the majority of these
customers. The Company also provides a full suite of voice, data, dedicated
access and Internet services to the City of Anaheim pursuant to a 30-year
contract. See "--Agreements with the City of Anaheim and The Irvine Company."
While not a primary component of the Company's long-term business plan, the
Company currently sells long distance services to individuals and businesses not
served by the Company's networks.
    
 
STRATEGIC RELATIONSHIPS
 
    The Company actively pursues strategic relationships with municipalities,
property developers and service providers as part of its core business strategy.
The Company believes that these relationships can provide it with enhanced brand
identity, access to physical assets, new products and technologies, joint
marketing synergies and other benefits, and thereby accelerate market rollout
and reduce asset deployment, sales costs and customer turnover.
 
    MUNICIPAL RELATIONSHIPS
 
    The Company seeks strategic relationships with municipalities in order to
obtain a network anchor customer, a "local" brand identity, media coverage and,
in certain circumstances, access to physical assets. The Company will, however,
pursue a network rollout into a region without a municipal alliance if the area
is otherwise commercially attractive.
 
    The Company's relationship with the City of Anaheim provides the Company
with the general benefits described above. The Company has exclusive commercial
rights to use the 50-mile fiber loop owned by the City of Anaheim and is now the
primary supplier of local dialtone, long distance, dedicated facilities and
Internet service to substantially all of its municipal facilities. See
"--Agreements with the City of Anaheim and The Irvine Company."
 
    DEVELOPER RELATIONSHIPS
 
    The Company pursues relationships with property developers in order to gain
access to prime commercial customers, to facilitate marketing of the Company's
products and services and, in some cases, to gain access to physical assets.
 
    The Company has developed a strategic relationship with The Irvine Company
to provide service to The Irvine Company's properties located within an area of
commercial properties in Irvine, California known as the "Irvine Spectrum." The
Irvine Company owns and has granted the Company access to 106 prime commercial
buildings within the Irvine Spectrum. The Irvine Spectrum, including the
buildings not owned by The Irvine Company, consists of approximately 25 million
square feet of commercial and
 
                                       48
<PAGE>
industrial space. The Company believes the tenant base is comprised of
businesses with greater-than-average demand for advanced telephony and data
communications services. The Irvine Company has granted the Company rights to
install fiber within an extensive existing conduit system, as well as building
access. The Irvine Company also promotes the Company's services in its marketing
materials to current and prospective tenants. The Company and The Irvine Company
also have established a framework for discussions regarding the Company's
providing services to tenants at Irvine Company properties throughout
California. See "--Agreements with the City of Anaheim and The Irvine Company."
 
    SERVICE PROVIDER RELATIONSHIPS
 
    The Company has established and intends to continue to establish
relationships with service providers in complementary industries to create
competitive or innovative products. In general, the Company expects these
service providers to contribute wholesale products, licenses of proprietary
technologies, specialized knowledge, sales and technical support or uniquely
situated fixed assets. In return, the Company generally expects to contribute
its network platform, sales force channels, operational support, engineering
expertise and wholesale purchases.
 
    ENRON.  The Company and Enron have an informal collaborative relationship to
jointly market telecommunications and utility services to municipalities,
project developers and other large wholesale markets and have presented a number
of joint proposals to municipalities. The Company believes that this
relationship can provide it with access to new markets, sales synergies and
product development opportunities. In this regard, Enron has commenced a major
initiative in California to compete with incumbent electric utilities to sell
wholesale electricity and utilities management services. Neither the Company nor
Enron is, however, obligated to pursue any opportunity or provide any service to
customers. The Company, however, has granted Enron exclusive rights to pursue
jointly with the Company any business opportunity with both telecommunications
applications and utility applications, and has agreed not to pursue any such
joint opportunity with any person other than Enron. See "Certain Transactions."
 
    NAVISITE.  The Company has entered into an agreement with Navi-Site Internet
Services Corporation, a national Internet protocol network ("NaviSite"), calling
for the two companies to establish a remote access MegaPOP at the Company's
central office. The MegaPOP would allow ISPs to provide local dial-up numbers to
customers located within the Southern California area. Under the agreement, the
Company provides power and space to NaviSite in the co-location room in the
Company's central office and helps manage and provision elements of network
connectivity. In return, NaviSite has granted the Company the right to resell
NaviSite's "GeoDial" service to ISPs throughout California and has granted the
Company "most favored purchaser" status, meaning that no other similarly
situated LEC will receive better GeoDial pricing than the Company.
 
NETWORK ARCHITECTURE AND TECHNOLOGY
 
    The Company has leveraged its substantial internal expertise with respect to
engineering, network creation and business processes to design and construct a
network architecture that it believes will result in enhanced product offerings
and enable the Company to improve scalability, reduce operating cost and improve
network profitability. The Company believes such expertise also will facilitate
the Company's implementation of new technologies. The following diagram
illustrates FirstWorld's network design.
 
                                       49
<PAGE>
                                   [LOGO]
 
    CENTRAL OFFICE.  The Company's central office in Anaheim is an integrated
computer/telephony facility which serves as the network operating center. The
facility houses a Nortel DMS-500 voice switch, the Company's Internet platform,
product servers primarily related to the Company's data products and co-located
equipment of strategic vendors. The facility has numerous elements of
redundancy, disaster recovery and remote recovery in order to meet or exceed
industry standards of reliability and best practices. The facility operates
24-hours a day and seven days a week. The Company believes the central office
will be sufficient to support its operations throughout Orange County.
 
    TRANSPORT.  The Company's networks consist of fiber optic clusters linked to
one another and to the central office through fiber optic backbones. The Company
builds clusters in areas with (i) high concentrations of customers with
sophisticated communications needs and a willingness to pay for direct fiber
connectivity or (ii) a large number of smaller customers that can be aggregated
on a fiber-optic cluster to reduce the Company's cost of service. The Company
uses SONET technology to ensure maximum reliability and continuity of service in
the event of equipment changes or upgrades. Customers are served from nodes or
hubs that are placed in strategic positions throughout the networks. The nodes
also contain redundant electronics that switch automatically to the backup
equipment in the event of a failure to protect the network from signal
deterioration or outages.
 
    The Company uses unmanned access offices as junctions to link network
clusters with the fiber backbone. As the Company expands into new areas, it will
need to install one or two additional access offices per network cluster,
depending on the size of the cluster. Each access office will store network
equipment and its own back-up power source. In addition, the Company has
established a number of remote computer/telephony facilities to interconnect
with the ILEC, IXCs and CLECs.
 
                                       50
<PAGE>
    CONNECTIVITY.  The Company typically connects prime commercial customers to
its networks through direct fiber connections. In such cases, the Company
installs fiber directly to the customer's premises and installs the CLE
necessary to provide the services requested by the customer.
 
   
    The Company complements its fiber roll-out by leasing unbundled loops from
Pacific Bell and GTE pursuant to interconnection agreements. The interconnection
agreements allow the parties to complete local and intraLATA toll calls on each
other's network and establish rates, terms and conditions for access to
unbundled network elements, resale of local exchange services, service provider
number portability and access to operator service, directory service and 911
service. The Company currently is exploring direct interconnection with the
major CLECs in Orange County, including MFS Communications, TCG, and the major
IXCs.
    
 
    Although the use of unbundled loops and other connections to reach off-fiber
customers limits the availability of some high-bandwidth products and services,
it enables the Company to serve businesses with its advanced services until
establishing fiber links with such customers becomes economically feasible. The
Company also intends to use wireless links and other transmission technologies
to reach customers when connecting customers through fiber or unbundled loops is
impractical.
 
OPERATIONAL SUPPORT SYSTEMS
 
    The Company believes its systems exhibit a high degree of scalability to
support network growth, flexibility to support product or technical innovation,
increased reliability and reduced operational cost. Management developed the
Company's business processes with respect to customer service, billing,
provisioning and network management systems based on extensive industry and
engineering expertise within the Company. The Company then developed systems,
incorporated systems from existing external sources and retained third parties
to produce systems meeting the Company's specifications to create integrated
systems that implement the Company's business processes.
 
    CUSTOMER CARE SYSTEM.  The Company has developed and is implementing a
Customer Care System designed to perform a wide variety of customer service
functions, including service order creation and tracking, telephone number
administration, trouble reporting and dispatch and billing inquiry. The Customer
Care System is designed to be a "point and click" system. Among other things,
the system simultaneously implements the customer's order, bills the customer
and updates equipment inventory. The Customer Care System allows a single
customer service person to solve most customer problems in real time without
having to refer the call to another department and in the future will allow
members of the Company's sales force to create a customer's service order while
at the customer's premises. The Company also expects that customers in good
standing will be permitted to access the system directly to request new services
beginning in the second quarter of 1999. In addition, the Company has
established a direct link between its Customer Care System and Pacific Bell's
operational support systems, which allows the Company to place orders for
additional unbundled loops directly with Pacific Bell's computers. The Company
believes placing orders electronically eliminates many of the errors that often
result when orders are placed by voice or fax.
 
    To develop the Customer Care System, the Company purchased a basic platform
and then enhanced its functions through joint efforts with the vendor of the
system, ACE*COMM Corporation ("ACE*COMM"). Under an agreement with the Company,
ACE*COMM is required to share with the Company revenues from future licenses of
software containing a substantial amount of the technology developed by it for
the Company up to the total license and service fees paid by the Company
pursuant to the agreement. ACE*COMM also provides data processing services to
the Company, including the preparation of customer invoices, pursuant to a
separate Data Processing Services Agreement.
 
    NETWORK MANAGEMENT SYSTEM.  The Network Management System developed by the
Company gives it the ability to monitor its networks from the central office to
customers' premises when customers are connected by fiber. In such cases, the
Network Management System notifies the Company's network
 
                                       51
<PAGE>
operations personnel of interruptions prior to, or simultaneously with, the
customer becoming aware of such problems. The Company also intends to deploy
devices currently under development by third parties that would allow the
Company to monitor its connection to customers across unbundled loops. The
Company expects such technology to allow the Company to quickly and efficiently
isolate sources of service disruption on unbundled loops, thereby reducing
system downtime.
 
NETWORK CONSTRUCTION STATUS AND PROPOSED EXPANSION
 
    ORANGE COUNTY
 
   
    The Company currently provides on-fiber services to customers connected to
fiber clusters in Anaheim. Additional clusters in Anaheim are either under
construction or authorized for construction with design completed and building
permits obtained. In addition, the Company has started construction within the
Irvine Spectrum area and has begun offering services to buildings in the Irvine
Spectrum. The Company has additional fiber clusters in Santa Ana, Irvine and
Orange that are currently under design, permitting or construction.
    
 
   
    The Company also currently provides off-fiber service to customers located
around two Pacific Bell central offices located in Anaheim through Pacific Bell
unbundled copper loops. The Company has applied for interconnections with
additional Pacific Bell central offices in Orange County by co-locating the
Company's equipment at such central offices in order to expand the areas in
which it can offer off-fiber services. These interconnections, which the Company
began establishing during the third quarter of 1998, will allow the Company to
offer services through Pacific Bell unbundled loops to businesses in most parts
of Orange County.
    
 
    SAN GABRIEL VALLEY AND SOUTH BAY
 
   
    The Company has commenced design, permitting and construction of fiber
clusters in the cities of Glendale, Burbank and Pasadena, which are located in
the San Gabriel Valley near Los Angeles, and in the City of Torrance, in the
South Bay area near Los Angeles. The Company anticipates that the San Gabriel
Valley and South Bay areas each will require a central office with its own
DMS-500 or equivalent switch. The Company also intends to co-locate equipment
with Pacific Bell central offices in both the San Gabriel Valley and the South
Bay areas. The Company has determined that such areas are home to high
concentrations of businesses with telecommunications and information needs
addressed by the Company's services. In addition, businesses in such areas tend
to be clustered together in business parks, which would allow the Company to
utilize its strategy of maximizing revenues from its installed base of fiber.
    
 
    FUTURE EXPANSION
 
    In addition to its planned networks in Orange County and the San Gabriel
Valley and South Bay areas of Los Angeles County, the Company intends
selectively to expand into additional markets by replicating the primary tenets
of its business plan. The Company will target future expansion based on analysis
of the number and density of businesses with heavy telecommunications usage in a
given area and current and anticipated competition from other telecommunications
providers. The Company has identified additional cities, both within and outside
of California, which it believes would be attractive markets for future
expansion. These target areas and their priority for expansion are subject to
continual re-evaluation in response to refinements in the Company's expansion
criteria and changes in the communications industry and in general economic
conditions. At this time, the Company has not made a decision regarding any
specific areas for future expansion beyond Orange County, San Gabriel Valley and
South Bay.
 
COMPETITION
 
    In each market area in which the Company is authorized to provide services,
the Company competes or will compete with several other service providers and
technologies. Most of the Company's competitors, particularly ILECs, have
long-standing relationships with customers and suppliers in their respective
 
                                       52
<PAGE>
industries, greater name recognition and significantly greater financial,
technical, marketing and other resources than the Company. The Company expects
to compete on the basis of service features, quality, price, reliability,
customer service and rapid response to customer needs.
 
    TELEPHONY.  The telephony services offered by the Company compete
principally with the services offered by ILECs in the areas served by the
Company's networks. The Company also competes with various CLECs in its target
markets, including MFS Communications, NEXTLINK, ICG, GST and Teleport. The ILEC
dominates each of the markets targeted by the Company. ILECs possess ubiquitous
infrastructure and the financial wherewithal to subsidize unprofitable deals to
maintain key customers. The Company competes with ILECs on the basis of price,
customer support and the ability to offer and provide value-added, integrated
service bundles. The Company has found that its CLEC competitors, unlike the
ILEC, tend to focus on particular segments within the market. The Company
competes with CLECs and ICPs by providing a variety of voice, data and Internet
services in different combinations to address the needs of different market
segments.
 
   
    The Company also faces, and expects to continue to face, competition from
other current and potential market entrants, including AT&T, MCI, Sprint,
WorldCom and other IXCs, wireless telephone system operators and private
networks built by large end users. AT&T has indicated its intention to offer
local telecommunications services in certain U.S. markets, either directly or in
conjunction with CLECs or cable operators. In January 1998 AT&T announced a plan
to acquire Teleport. The deal, if consummated, would allow AT&T to sell
integrated local, long-distance and data communications services to businesses
in the areas served by Teleport. AT&T has also announced plans to merge with
TCI, the nation's largest operator of cable television systems, and to provide
telephone services over the TCI cable plant. Sprint recently announced plans to
deploy an advanced telecommunications network intended to boost speed and
capacity, cut costs and provide an integrated platform to enter local markets,
and has signed access agreements with a number of RBOCs and GTE. WorldCom
already has acquired MFS Communications and Brooks Fiber Properties, Inc., both
major CLECs, and WorldCom has agreed to acquire MCI, subject to regulatory
approvals. Recently Ameritech and US West have announced plans to enter the long
distance market by forming joint sales ventures with Qwest, a growing provider
of fiber optic-based telecommunications services. Although the legality of these
particular deals with Qwest have been challenged as a result of actions brought
by AT&T and MCI and remain subject to judicial and FCC review, a continuing
trend toward combinations and strategic alliances in the telecommunications
industry, including combinations or potential consolidations among RBOCs or
CLECs, or between IXCs and CLECs, could give rise to significant new competitors
for the Company. The Company also expects increased competition from ILECs
operating outside of their current local service areas, cable television
systems, electric utilities, microwave and other wireless carriers and satellite
licensees. In addition, sweeping changes mandated by the Telecommunications Act
will facilitate entry by new competitors into local exchange and exchange access
markets, including requirements that ILECs make available interconnection and
unbundled network elements at cost-based rates, and resell their services to
requesting competitors at wholesale discounts.
    
 
    INTERNET SERVICES.  The Internet services market is extremely competitive,
and the Company expects competition in this market to intensify in the future.
The Company's current and prospective competitors include many large companies
that have substantially greater market presence and financial, technical,
marketing and other resources than the Company. The Company competes (or in the
future is expected to compete) directly or indirectly with the following
categories of companies: (i) national and regional ISPs; (ii) established
on-line services; (iii) computer software and technology companies; (iv)
national telecommunications companies; (v) RBOCs; (vi) cable operators; and
(vii) nonprofit or educational ISPs. The entry of new participants from these
categories and the potential entry of competitors from other categories (such as
computer hardware manufacturers) would result in substantially greater
competition for the Company.
 
                                       53
<PAGE>
    ADVANCED NETWORK SERVICES.  In the markets for data services and other
advanced network services, the Company will face competition from a number of
companies focused on the LAN and WAN market, including companies with
significantly greater financial resources, more extensive business experience,
and greater market and service capabilities than the Company. In particular, the
Company will be required to compete with companies that design and manufacture
products for the LAN and WAN markets and large system integrators.
 
    Substantially all of the Company's current and prospective competitors in
the markets for advanced networking services have substantially greater market
presence and financial, technical, marketing and other resources than the
Company. See "Risk Factors--Competition."
 
REGULATION
 
    OVERVIEW
 
    The Company's services are subject to regulation by federal, state and local
governmental agencies. The Company has obtained all authorizations and approvals
necessary to conduct its operations as currently structured and believes that it
is in compliance with all laws, rules and regulations governing its current
operations. Nevertheless, changes in existing laws and regulations or any
failure or significant delay in obtaining necessary future regulatory approvals,
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
    At the federal level, the FCC has jurisdiction over interstate and
international telecommunications services. State regulatory commissions have
jurisdiction over intrastate communications. Municipalities and other local
jurisdictions may regulate limited aspects of the Company's business by, for
example, regulating the use of rights-of-way, imposing zoning and franchise
requirements, and requiring installation permits. The Company also is subject to
taxation at the federal and state levels and may be subject to varying taxes and
fees from local jurisdictions.
 
    FEDERAL LEGISLATION
 
    THE TELECOMMUNICATIONS ACT OF 1996.  The Telecommunications Act, enacted on
February 8, 1996, substantially departs from prior legislation in the
telecommunications industry by establishing local exchange competition as a
national policy through the removal of state regulatory barriers to competition
and the preemption of laws restricting competition in the local exchange market.
The Telecommunications Act, among other things, mandates that (i) ILECs permit
resale of their services and facilities on reasonable and nondiscriminatory
terms and at wholesale rates, (ii) all LECs (including the Company) allow
customers to retain the same telephone number ("number portability") when they
switch local service providers, (iii) ILECs permit interconnection by
competitors to an ILEC's network at any technically feasible point that is at
least equal in quality to that which the ILEC provides to itself and pursuant to
reasonable and nondiscriminatory terms and cost-based rates, (iv) ILECs unbundle
their network services and facilities at any technically feasible point and
permit competitors and others to use these facilities at cost-based, reasonable
and nondiscriminatory rates, (v) all LECs ensure that an end user
does not have to dial any more digits to reach customers of local competitors
than to reach the ILEC's customers to the extent technically feasible ("dialing
parity") and (vi) all LECs must establish reciprocal compensation arrangements
for the transport and termination of telecommunications traffic.
 
   
    The Telecommunications Act permits RBOCs to provide out-of-region interLATA
long distance services immediately, and also allows RBOCs to provide in-region
interLATA services on a state-by-state basis once certain market-opening
requirements are implemented and entry is determined to be in the public
interest. The RBOCs, but not other ILECs, have an added incentive to open their
local exchange networks to facilities-based competition because Section 271 of
the Telecommunications Act provides for the removal of the current ban on RBOC
provision of in-region interLATA toll service only after meeting certain
requirements. The FCC, in consultation with the United States Department of
Justice and the states, is given jurisdiction to determine whether to approve
applications for RBOC entry into long
    
 
                                       54
<PAGE>
   
distance. These provisions of the Telecommunications Act are designed in part to
ensure that RBOCs take affirmative steps to level the playing field for their
competitors so that others can compete effectively before the RBOC secures
in-region long-distance entry. To date, three RBOCs have filed applications with
the FCC for "in-region" long distance authority. The FCC denied the application
of SBC with respect to Oklahoma in June 1997; denied the application of
Ameritech in August 1997 with respect to Michigan; and denied applications filed
by BellSouth for South Carolina and Louisiana in December 1997 and February
1998, respectively. Several entities have sought reconsideration of the FCC's
decisions and some have initiated litigation claiming, among other things, that
Section 271 of the Telecommunications Act is unconstitutional, that the FCC has
exceeded its jurisdiction, and that the FCC has violated the Eighth Circuit's
ruling on the Interconnection Orders (discussed below) in several respects,
e.g., by effectively promulgating national pricing standards. See "--Federal
Regulation."
    
 
    RBOC entry into long distance services under Section 271 of the
Telecommunications Act has, over the past year, also become a contentious
political issue. Several ranking members of Congress, including Rep. John
Dingell (D-MI) and Rep. W.J. "Billy" Tauzin (R-LA), have voiced strong
frustration at what they allege is an unwillingness by the FCC to grant RBOC
applications for long distance authority. In response, William Kennard, Chairman
of the FCC, announced in early 1998 that the FCC will, in the future, take a
more "cooperative" position with respect to RBOC applications under Section 271
of the Telecommunications Act and work closely with each RBOC to identify and
resolve issues arising in connection with RBOC entry into the long distance
service market. It is not certain at this time whether Chairman Kennard's
announcement indicates that, in the future, the FCC is prepared to grant RBOC
applications for in-region provision of interLATA long distance services.
 
    The U.S. District Court for the Northern District of Texas declared Section
271 unconstitutional in late December 1997. If the court's decision (which has
been stayed pending appeal) is upheld, Pacific Bell, among other RBOCs, will be
able to provide more services to customers, making it an even more formidable
competitor for the Company. See "Risk Factors--Competition."
 
    Under the Telecommunications Act, states have begun and, in a number of
cases, completed regulatory proceedings to determine the pricing of unbundled
network elements and services, and the results of these proceedings will
determine whether it is economically attractive to use these elements.
 
    FEDERAL REGULATION
 
   
    THE TELECOMMUNICATIONS ACT REGULATIONS.  The Telecommunications Act in some
sections is self-executing, but in most cases the FCC must issue regulations
that identify specific requirements before the Company and its competitors can
proceed to implement the changes the Telecommunications Act prescribes. The
Company actively monitors pertinent FCC proceedings and has participated in some
of these proceedings (including the restructuring of access charges, the
application of access charges to Internet traffic and RBOC petitions for the
deregulation of ILEC-provided DSL services). The outcome of these various
ongoing FCC rulemaking proceedings or judicial appeals of such proceedings could
materially affect the Company's business, financial condition and results of
operations.
    
 
    As required by the Telecommunications Act, in July and August 1996 the FCC
adopted orders issuing new rules to implement the interconnection and resale
provisions of the Telecommunications Act (the "Interconnection Orders") which
are intended to remove or minimize regulatory, economic and operational
impediments to full competition for local services, including switched local
exchange service. A number of parties filed petitions for review of the
Interconnection Orders in Federal court seeking to vacate certain of the rules
adopted therein. In a July 18, 1997 decision, the United States Court of Appeals
for the Eighth Circuit vacated significant portions of the Interconnection
Orders, including its provisions governing the pricing of local
telecommunications services and unbundled network elements, its unbundling
requirements and its "pick and choose" rule (which enabled a telecommunications
carrier to demand any individual term of an ILEC's interconnection contract with
another carrier). Another Eighth Circuit decision issued on October 14, 1996
vacated an FCC rule that obligated ILECs, under certain
 
                                       55
<PAGE>
   
circumstances, to provide combinations of network elements, rather than provide
them individually. This decision may make it more difficult or expensive for
competitors to use combinations of ILEC unbundled elements. On August 22, 1997,
the Eighth Circuit vacated the FCC's interconnection rules implementing the
Telecommunications Act dialing parity requirement for LECs. In November 1997,
the FCC, AT&T, MCI, and a number of CLECs sought review of the Eighth Circuit's
decisions by the Supreme Court. The RBOCs and GTE also cross-petitioned for
Supreme Court review of several aspects of the Interconnection Orders that were
upheld by the Eighth Circuit in the event Supreme Court review were granted.
While these petitions were pending, the Eighth Circuit on January 23, 1998,
found that the FCC had violated the terms of its July decision, and ordered the
FCC to cease imposing its local pricing rules on RBOCs attempting to enter the
long distance market under Section 271 of the Act. On January 26, 1998, the
Supreme Court agreed to review the Interconnection Orders, with oral argument
calendared for October 1998. A Supreme Court decision in the cases is not
expected until some time in late 1998 or 1999.
    
 
    The Eighth Circuit decisions and Supreme Court grant of review create
uncertainty about individual state rules governing pricing and other terms and
conditions of interconnection agreements and could make negotiating and
enforcing such agreements in the future more difficult and protracted. They also
could require renegotiation of relevant provisions of existing interconnection
agreements, or subject them to additional court or regulatory proceedings.
Although the Company generally believes that the outcome of the these judicial
proceedings will not have a material adverse effect on its business and
operations, there can be no assurance that this will be the case.
 
   
    In July 1996, the FCC mandated that over the course of the next year
responsibility for administering and assigning local telephone numbers be
transferred from the RBOCs and a few other ILECs to a neutral entity. In August
1996, the FCC issued regulations which address certain of these issues, but
leave others for decision by the states and the still-to-be selected neutral
numbering plan administrator. In August 1997, the FCC designated two neutral
numbering plan administrators and the process of transferring numbering
administration to these entities is underway. The FCC numbering decisions, among
other things, (a) prohibit states from creating new area codes that could
unfairly hinder LEC competitors (including the Company) by requiring their
customers to use 10 digit dialing while existing ILEC customers use 7 digit
dialing, and (b) prohibit ILECs (which in many cases are still administering
central office numbers pending an operational transition to the neutral
administrator) from charging "code opening" fees to competitors (such as the
Company) unless they charge the same fee to all carriers including themselves.
In addition, each carrier is required to contribute to the cost of numbering
administration through a formula based on net telecommunications revenues. In
July 1996, the FCC released rules to permit both residential and business
customers to retain their telephone numbers when switching from one local
service provider to another (known as "number portability"). RBOCs were required
to implement number portability in the top 100 markets in five phases beginning
no later than March 31, 1998 and to complete it no later than December 1998,
although the FCC has granted numerous waivers of these implementation deadlines.
In smaller markets, RBOCs must implement number portability within six months of
a request therefore commencing December 31, 1998. Non-RBOC ILECs are not
required to implement number portability in any additional markets until
December 31, 1998, and then only in markets where the feature is requested by
another ILEC. The Company's initial service areas in Orange County are scheduled
to have permanent local portability implemented by June 30, 1998.
    
 
   
    In addition, pursuant to the Telecommunications Act, the FCC issued new
regulations in 1997 regarding the implementation of the universal service
program and the assessment of charges on carriers obtaining access to local
exchange networks. Both the access charge and universal service regimes were
substantially revised. As a result of these changes, the costs of business and
multiple residential lines are expected to increase. Several parties have sought
FCC reconsideration or judicial review of various parts of the new FCC rules,
including the revenue basis on which universal service contributions are
determined. The FCC is currently examining whether IXCs and CLECs will be
permitted, and if so in what manner and to what extent, to pass through
universal service charges to end users as line item surcharges on bills for
telecommunications services. In addition, in June 1998 the FCC announced that it
was restructuring and
    
 
                                       56
<PAGE>
narrowing universal support for provision of Internet services to schools,
libraries and rural health care providers. As a result of this rapidly changing
environment, the Company is unable to predict how the FCC's universal service
and access charge reforms will be finally implemented or enforced, or what
effect they will have on competition within the telecommunications industry,
generally, or on the competitive position of the Company, specifically. The
Company also is unable to accurately predict the final formula for universal
service contribution or its own level of contribution in 1999 and beyond.
 
    The Telecommunications Act requires the FCC to streamline its regulation of
ILECs and permits the FCC to forbear from regulating particular classes of
telecommunications services or providers. Since the Company is a non-dominant
carrier and, therefore, is not heavily regulated by the FCC, the potential for
regulatory forbearance likely will be more beneficial to ILECs than the Company
in the long run. In June 1997, the FCC granted the request of a CLEC that the
FCC forbear from imposing tariff filing requirements on exchange access services
provided by carriers other than ILECs. The FCC has sought further comment on
whether to mandate the detariffing of exchange access services. The proceeding
remains pending, and there can be no assurance how the FCC will rule on this
issue, or what effect any such ruling may have on competition within the
telecommunications industry generally, or on the competitive position of the
Company specifically.
 
    There also is a risk that Telecommunications Act requirements that currently
work in the Company's favor may be implemented differently in the future
depending on marketplace developments. For example, many CLECs such as the
Company have begun to acquire an increasing number of ISP customers. This
development in turn has resulted in a rapid increase in Telecommunications
Act-mandated reciprocal compensation charges paid by ILECs to CLECs to terminate
the calls of ILEC customers to CLEC ISP customers. ILECs led by the RBOCs
currently are pursuing action in the courts and before state PUCs and the FCC to
address this issue. The outcome of such actions is uncertain, but could have a
material adverse effect on the Company.
 
   
    Section 706 of the Telecommunications Act requires the FCC to initiate a
proceeding to address the provision of "advanced telecommunications services" to
all Americans. In early 1998, several RBOCs (Bell Atlantic, Ameritech, BellSouth
and SBC) filed petitions with the FCC seeking forbearance from FCC and state
regulation of their DSL high-speed data services. The RBOCs also seek an FCC
ruling under Section 706 that elements of their DSL services are not subject to
the interconnection, unbundling and resale requirements of the
Telecommunications Act. In response to these petitions, the FCC on August 6,
1998 proposed that RBOCs be permitted to offer DSL services on an unregulated
basis if certain separate subsidiary and interconnection requirements are met.
Although the Company does not, at the present time, anticipate utilizing RBOC
DSL or other high-speed services under its interconnection agreements, any grant
of regulatory relief by the FCC would likely permit Pacific Bell to introduce
DSL-based services, in competition with the Company, on a more rapid basis and
at reduced costs to Pacific Bell than under current regulatory rules. There can
be no assurance that these or similar RBOC regulatory initiatives regarding
broadband service provision would not have a material adverse effect on the
Company's business, financial condition and results of operations.
    
 
    STATE REGULATION
 
    Many of the Company's services will be classified as intrastate services
subject to state regulation. All of the states where the Company operates, or
will operate, require some degree of state regulatory commission approval to
provide certain intrastate services. In most states, intrastate tariffs are also
required for various intrastate services, although the Company is not typically
subject to price or rate of return regulation for tariffed intrastate services.
The Company may also be subject to a variety of other state regulatory
requirements, including interconnection, universal service, reporting and
customer service requirements.
 
    The Telecommunications Act requires each state to remove barriers to entry
and barriers to competition for ILEC competitors. While no assurance can be
given as to how quickly and how effectively each
 
                                       57
<PAGE>
state will act to implement this legislation, many state authorization processes
are being streamlined and the authorization time frames shortened considerably.
Several states have allowed ILECs rate, special contract (selective discounting)
and tariff flexibility, particularly for services deemed subject to completion.
Such pricing flexibility increases the ability of the ILEC to compete with the
Company and constrains the rates that the Company may charge for its services.
In view of the additional competition expected to result from the
Telecommunications Act, states may grant ILECs additional pricing flexibility.
At the same time, some ILECs may request increases in local exchange rates to
offset revenue losses due to competition.
 
   
    Under the Telecommunications Act, if a request is made by the Company, ILECs
generally have a statutory duty to negotiate interconnection and access
arrangements in good faith for the Company's provision of local service (unless
they are exempted from such requirement as small or rural ILECs). The Company
has completed interconnection agreements with Pacific Bell and GTE for
California. During these negotiations, the Company or the ILEC may submit
disputes to the state regulatory commissions for mediation and, after the
expiration of the statutory negotiation period set forth in the
Telecommunications Act, the parties may submit outstanding disputes to the
states for arbitration. To date the Company has not submitted any disputes to
the states for mediation or arbitration.
    
 
    LOCAL REGULATION
 
    The Company will need to interact with local governments in a variety of
ways, and may be required to obtain various permits and authorizations from
municipalities in which it operates. How diverse local governments will exercise
traditional functions, including zoning, permitting and management of rights of
ways, and address the expansion of telecommunications competition and varying
means of entry in particular, is uncertain. The kinds and timing of approvals
required to conduct aspects of the Company's business varies among local
governments and may also vary with the specific technology or equipment
configuration used by the Company.
 
   
    While the Telecommunications Act permits local governments to manage rights
of way, the scope of that authority, including the circumstances when fees can
be charged and the amount of such charges, has already been the subject of
numerous disputes between telecommunications carriers and such local
governments. In addition, some local governments have been requiring substantial
filings and review before telecommunications carriers can operate in their
licensed areas and have also required the payment of significant franchise fees
or taxes. Some of these disputes involving licensing of telecommunications
carriers and rights of way are in litigation and more administrative and court
litigation is likely. The prohibition of entry barriers set forth in the
Telecommunications Act and the FCC's power to preempt such barriers have been
addressed in these cases, which to date have rejected local government efforts
to impose "franchise" or tax obligations on CLECs and other telecommunications
carriers. The FCC has recently preempted, and thereby prevented enforcement of,
certain state and local regulations that had the effect of inhibiting local
competition. Any inability or unwillingness by the FCC to preempt additional
state and local regulations in a timely fashion could have a material adverse
impact on the Company.
    
 
AGREEMENTS WITH THE CITY OF ANAHEIM AND THE IRVINE COMPANY
 
    THE CITY OF ANAHEIM
 
    The Company, its wholly owned subsidiary, FirstWorld Anaheim ("FWA"), and
the City of Anaheim (the "City") entered into a series of agreements in February
1997 regarding development of the first portion of the Company's initial network
located within the City (the "Anaheim Network").
 
    AGREEMENT FOR USE OF OPERATING PROPERTY.  Pursuant to an Agreement For Use
of Operating Property (the "Operating Property Agreement"), FWA leases from the
City 60 of 96 fiber strands contained in an approximately 50 mile long loop of
fiber optic cable owned by the City, together with related facilities and
rights. The term of the agreement runs through December 31, 2027, and during
calendar year 2011 the
 
                                       58
<PAGE>
parties are obligated to negotiate in good faith concerning a possible 15-year
extension of the term (through December 31, 2042).
 
    The remaining 36 fiber strands within the cable (the "Reserved Fibers") are
reserved by the City for its own use in providing municipal services (i.e., uses
that are not competitive with FWA's commercial uses). If the City determines
from time to time that some portion of the Reserved Fibers is not required for
municipal services, then the City and FWA are to negotiate in good faith the
terms and conditions on which that portion of the Reserved Fibers will be leased
to FWA. In any event, the City can use the Reserved Fibers only for municipal
services unless FWA fails to proceed with development of the third phase of the
Anaheim Network (as described below) and the City proceeds with the development
of the third phase of the Anaheim Network for its own account, as described
below.
 
    As rent for the 60 strands of fiber, FWA is obligated to make quarterly
payments to the City of approximately $114,000. In addition, FWA is obligated to
pay all costs associated with operating and maintaining the leased property,
including maintenance expenses, taxes, insurance premiums and pole usage fees.
FWA also is obligated to maintain and insure the leased property and the City's
Reserved Fibers (except to the extent the Reserved Fibers are located on certain
identified City-owned premises, such as electrical substations), subject to the
City's obligation to reimburse FWA for a pro rata share of maintenance and
insurance costs (computed based on the number of Reserved Fibers relative to the
total of 96 fibers).
 
    FWA has the right to assign its rights under the Operating Property
Agreement, but will not be released from liability unless the City expressly
consents. FWA also has the right to encumber its interest in the leased
property. FWA's interest in the leased property is not currently encumbered.
 
    UNIVERSAL TELECOMMUNICATIONS SYSTEM PARTICIPATION AGREEMENT.  Concurrently
with the execution of the Operating Property Agreement, the City, FWA and the
Company executed the UTS Agreement which sets forth guidelines for FWA's
development and operation of the Anaheim Network and compensation payable to the
City by FWA. The term of the UTS Agreement runs through December 31, 2027, and
during calendar year 2011 the parties are obligated to negotiate in good faith
concerning a possible 15-year extension of the term (through December 31, 2042).
 
    The UTS Agreement provides that FWA will construct the Anaheim Network in
three phases. The first phase extended service to identified municipal
facilities and was substantially completed in October 1997. The second phase
requires service to be extended in the ordinary course of business (I.E., within
six months following execution of a customer service agreement) to commercial,
industrial and governmental customers within certain defined service areas. The
Company was required to complete 44% of the first and second phases by April 1,
1998 and is further required to complete 90% of the first and second phases by
December 31, 1998, plus a 180-day cure period in each case. The Company
constructed and installed sufficient fiber to satisfy the 44% completion
requirement prior to April 1, 1998 and expects completion of the fiber clusters
currently under construction and approved for construction to satisfy the 90%
completion requirement in a timely manner. See "--Network Construction Status
and Proposed Expansion."
 
    The third phase of the Anaheim Network requires that service be extended in
the ordinary course of business to all customers within Anaheim, including
residential customers. This phase will be commenced only after the feasibility
of the third phase is validated by an independent consultant's report and
financing is arranged. FWA has agreed to cause a feasibility study with respect
to the third phase to be completed by no later than January 1, 2000, and
thereafter to prepare annual updates of the study if necessary. If FWA
determines not to proceed with the development of the third phase of the Anaheim
Network, or if for any reason the principal financing for the third phase is not
funded or construction of the third phase is not commenced by December 31, 2002,
then the City may pursue development of the third phase on its own (including in
a business arrangement with third parties). If the City closes the principal
financing for or commences construction of the third phase, then the provisions
of the Operating Property Agreement prohibiting the City from using the Reserved
Fibers for other than municipal services terminate.
 
                                       59
<PAGE>
    Under the UTS Agreement, the City is obligated, with specified exceptions,
to utilize FWA as the provider of all of the City's telecommunications services,
and to provide FWA with certain rights-of-way. The UTS Agreement requires FWA to
pay to the City (i) an annual payment in lieu of a franchise fee based on a
percentage of FWA's "adjusted gross revenues," as defined, related to the
Anaheim Network, subject to a minimum annual payment of $1,000,000 for periods
after June 30, 1999, (ii) a percentage of FWA's "net revenues," as defined,
derived from the Anaheim Network, (iii) certain of the City's annual operating
costs associated with the UTS Agreement, not to exceed $175,000 per year prior
to the commencement of the third phase of the Anaheim Network, and not to exceed
$350,000 per year thereafter (as adjusted annually to reflect changes in the
cost of living), and (iv) $20,000 per year (adjusted annually to reflect changes
in the cost of living) to support the City's presence on the Internet. The UTS
Agreement also requires the Company to deposit an amount equal to up to 15% of
"net revenues" derived from the Anaheim Network to maintain a $6,000,000 reserve
account for debt service and capital improvements.
 
   
    The UTS Agreement originally required FWA to commence construction of a
demonstration center in the City's downtown area by August 20, 1998, and to
complete the demonstration center by June 30, 1999. However, in connection with
a significant expansion of the proposed scope of the project, the Company, FWA
and the City are currently negotiating extensions of such deadlines.
Contemplated plans now include the construction of an approximate 56,000 square
foot building which will include the demonstration center and FirstWorld
offices.
    
 
    The City has an option to purchase all of the issued and outstanding stock
of FWA for appraised value (i) at any time after July 1, 2012 or (ii) if FWA
fails to meet the specified performance deadlines related to completion of the
first and second phases of the Anaheim Network as described above. Any sale or
issuance of FWA stock can only be made if such sale or issuance is expressly
made subject to the City's purchase option. Moreover, any sale of the Anaheim
Network or other sale of substantially all of FWA's assets can only be made if
the City is equitably compensated for the loss of its future income stream under
the UTS Agreement or the buyer expressly assumes the obligations of FWA under
the UTS Agreement.
 
    DEVELOPMENT FEE AGREEMENT.  Pursuant to a Development Fee Agreement between
the Company and the City, for a period of five years commencing with the earlier
to occur of the closing of the financing for, or the commencement of,
construction of the first Additional Network (as defined below), the Company
must pay to the City a lump sum fee for each Additional Network that the Company
develops ($300,000 for each Additional Network financed in the first year;
$200,000 for each Additional Network financed in the second year; and $100,000
for each Additional Network financed in the third, fourth and fifth years)
(each, a "Development Fee"). Each Development Fee must be paid within 30 days
after the closing of the principal financing for an Additional Network or the
commencement of construction of such Additional Network, whichever occurs first.
"Additional Network" means (a) any expansion of the Anaheim Network into one or
more adjacent or nearby cities where FWA enters into a revenue sharing agreement
with any such city, and (b) any separate communications system developed by any
other subsidiary of the Company that holds a Certificate of Public Convenience
and Necessity issued by the California Public Utilities Commission and enters
into a revenue sharing agreement with one or more public entities. No such fee
is due, however, with respect to the Company's relationship with The Irvine
Company because it is not a public entity.
 
    THE IRVINE COMPANY
 
    FirstWorld Orange Coast ("FWOC"), a wholly-owned subsidiary of the Company,
and The Irvine Company entered into two agreements in February 1998 regarding
FWOC's development of a network to serve certain areas that have been or are
planned to be developed by The Irvine Company (the "Irvine Network").
 
                                       60
<PAGE>
    AGREEMENT FOR LEASE OF TELECOMMUNICATIONS CONDUIT
 
    Pursuant to an Agreement for Lease of Telecommunications Conduit dated as of
March 5, 1998 (the "Conduit Lease"), FWOC leases from The Irvine Company space
within two underground telecommunications tubes (the "Conduit"), and, in
connection therewith, has received the non-exclusive right to use undivided
space within the pull boxes serving such Conduit (collectively, the "Leased
Premises"). The Conduit Lease applies to (i) an existing Conduit system within
certain already-developed areas in the Irvine Spectrum and (ii) Conduit to be
constructed in the future in the as yet undeveloped areas of the Irvine
Spectrum. The Irvine Company may also install Conduit in other areas it may
develop in the cities of Irvine, Newport Beach and Tustin, and in unincorporated
areas of Orange County, and such areas may in the future be incorporated into
the Conduit Lease upon the mutual agreement of the parties ("Additional Areas").
The term of the Conduit Lease runs through December 31, 2027.
 
    The Conduit Lease obligates FWOC to install fiber optic cable ("Cable") in
the Conduit pursuant to a phasing plan. A phase is completed when sufficient
Cable has been installed to enable FWOC to connect and provide service (for that
portion of the Irvine Network) to property abutting the Conduit. Upon
termination of the Conduit Lease, the Cable will be owned by The Irvine Company.
If FWOC fails to complete installation of the required Cable within 18 months,
The Irvine Company may, until such installation is completed, terminate the
Conduit Lease.
 
    FWOC is obligated to make quarterly rent payments to The Irvine Company
based upon the "adjusted gross revenue" (as defined) from the Irvine Network. In
addition, FWOC is obligated to pay all costs associated with its lease,
operation, maintenance, repair and use of the Leased Premises, including
maintenance expenses, taxes and insurance premiums. Any assignment of FWOC's
rights under the Conduit Lease and any sale of a controlling interest in FWOC
require The Irvine Company's prior approval, and The Irvine Company has a right
of first refusal in the event of any such proposed sale.
 
    TELECOMMUNICATIONS SYSTEM LICENSE AGREEMENT
 
    Concurrently with the execution of the Conduit Lease, FWOC and The Irvine
Company executed a Telecommunications System License Agreement (the "License
Agreement"), which provides FWOC, with some exceptions, with the right and
obligation to provide telecommunications services to (i) the 106 buildings
currently owned by The Irvine Company in the Irvine Spectrum area, (ii)
commercial, industrial and retail buildings in the future owned by The Irvine
Company in the Irvine Spectrum, and (iii) under certain circumstances in The
Irvine Company's discretion, similar buildings located in the Additional Areas
and other locations in California.
 
    The License Agreement requires FWOC to pay The Irvine Company a license fee
each calendar quarter, subject to an annual CPI increase that will not be less
than 2% or greater than 6%. The license fee will increase or decrease in the
future based on the rentable square footage of the buildings that are from time
to time subject to the License Agreement.
 
    The License Agreement provides FWOC with the right to install, maintain,
operate, replace and remove Cable and associated communications equipment
("Equipment") in, as well as access rights to, such buildings, subject to the
rights of The Irvine Company's tenants and to reasonable requirements and
procedures imposed by The Irvine Company. Except with respect to buildings that
are leased to a single tenant, The Irvine Company is required to provide FWOC
with a reasonable amount of equipment room space in each building, sufficient to
enable FWOC to install Cable and Equipment and deliver services. FWOC's rights
to a building are non-exclusive, meaning that The Irvine Company can grant
similar licenses to other service providers. Although all the Cable becomes the
property of The Irvine Company upon termination of the License Agreement, FWOC
has the right to remove and retain ownership of the Equipment, subject to The
Irvine Company's election to purchase the Equipment at a price to be negotiated
by the parties.
 
                                       61
<PAGE>
    Subject to certain qualifications, FWOC will have the obligation to provide
telecommunications services to any tenant who wishes to subscribe with FWOC for
those services, and FWOC is required to install Cable and Equipment in that
tenant's building if FWOC owns or leases Conduit located within 1,000 feet of
that building. Under certain circumstances, FWOC may be required to provide
completion and performance bonds to The Irvine Company in connection with that
work.
 
    To the extent that FWOC provides fiber optic service to a building, it is
required to achieve and maintain standards of minimum reliability. Subject to
force majeure, if there is a system-wide failure to provide such service that
exceeds five consecutive days, The Irvine Company has the right to use the
network (and if necessary bring in an alternative service provider) and to
charge its costs to FWOC.
 
    Whenever FWOC is the first competitive access provider to a building, it is
required to install a building entrance conduit system (which connects the
building to the street access point) (a "BECS"), with a capacity equal to 200%
of the capacity required by FWOC to service the building. The Irvine Company can
grant other providers the right to use that BECS, but must pay or cause that
provider to pay FWOC 50% of FWOC's cost of installing the BECS, which costs are
subject to increase based on a CPI calculation. Where a BECS already exists, The
Irvine Company must make any excess capacity therein available to FWOC.
 
    The Company has guaranteed the payment obligations of FWOC under The Irvine
Company agreements.
 
EMPLOYEES
 
   
    As of July 31, 1998, the Company had 135 employees, of whom 54 were in
network operations and development, 53 were in sales, marketing and product
development and 28 were in administration. The Company believes that its future
success will depend in part on its continued ability to attract, hire and retain
qualified personnel. Competition for such personnel is intense, and there can be
no assurance that the Company will be able to identify, attract and retain such
personnel in the future. None of the Company's employees are represented by a
labor union or are the subject of a collective bargaining agreement. The Company
has never experienced a work stoppage and believes that its employee relations
are good.
    
 
PROPERTIES
 
   
    The Company's headquarters are located in facilities consisting of
approximately 35,000 square feet in San Diego, California, which the Company
occupies under a lease that expires on August 31, 2002. The Company's central
office in Anaheim, California occupies approximately 8,900 square feet of space
under a lease expiring on October 31, 2001. In addition, pursuant to its
agreement with the lessor of the central office, the Company has (i) the option
to purchase the central office through October 1998 for approximately $600,000
and (ii) a right of first refusal to purchase the central office during the term
of the lease and any extensions thereof. The Company also leases offices and
space in a number of other locations for sales offices and network equipment
installations.
    
 
LEGAL PROCEEDINGS
 
    The Company is not a party to any legal proceedings.

    The Company adopted the SpectraNet International 1995 Incentive Stock Option
Plan (the "1995 Stock Option Plan") in 1995 to incentivize certain employees of
the Company by enabling them to acquire or increase their proprietary interest
in the Company and to encourage continued service with the Company. The 1995
Stock Option Plan will terminate on April 10, 2005, unless sooner terminated by
the Board of Directors. The Company is authorized to issue incentive stock
options ("ISOs") as defined in the Internal Revenue Code of 1986, as amended, to
acquire up to an aggregate of 1,500,000 shares of Series B Common Stock pursuant
to the 1995 Stock Option Plan.
 
    Subject to the limitations set forth in the 1995 Stock Option Plan, the
Board of Directors or a committee thereof comprised of at least three directors
has the authority, subject to certain limitations, to select the employees of
the Company or its subsidiaries to whom grants are made, to designate the number
of shares to be covered by each option, to establish vesting schedules, and to
specify other terms of the options. Generally, options vest over a four and one
half year period and expire ten years from the date of grant. Options granted
under the 1995 Stock Option Plan are nontransferable and expire 90 days after
the termination of an optionee's employment with the Company, unless such
optionee's service with the Company is terminated by death or disability, in
which case such options expire six months and one year, respectively, after the
optionee's employment with the Company is terminated. In addition pursuant to an
amendment to the 1995 Stock Option Plan adopted by the Board of Directors in
December 1997, if an employee is terminated without "cause" prior to June 30,
1998, then all options held by such optionee become immediately vested and
exercisable.
 
    The exercise price of options granted under the 1995 Stock Option Plan is
determined by the Board of Directors (or a committee thereof) at the time of
grant. The exercise price of options must be no less than the fair market value
of the Series B Common Stock on the date of grant. The exercise price of options
granted to an employee who owns more than 10% of the total combined voting power
of all classes of stock must be at least 110% of the fair market value of the
Series B Common Stock on the date of grant, and the term of these options cannot
exceed five years. As of May 31, 1998, options to purchase an aggregate of
702,400 shares of Series B Common Stock at prices ranging from $.15 to $.50 were
outstanding under the 1995 Stock Option Plan.

    1997 STOCK OPTION PLAN
 
    The Company adopted the SpectraNet International 1997 Stock Plan (the "1997
Stock Option Plan") in 1997 to attract and retain personnel for positions of
substantial responsibility and to provide additional incentives to existing
employees, consultants and directors. The 1997 Stock Option Plan provides for
the grant of both stock options intended to qualify as ISOs and nonqualified
stock options ("NQSOs"). The 1997 Stock Option Plan terminates on April 22,
2007, unless sooner terminated by the Board of Directors. Pursuant to an
amendment duly adopted by the Board and approved at the 1998 Annual Meeting of
Stockholders, the 1997 Stock Option Plan provides for aggregate option grants of
up to 1,500,000 shares of Series B Common Stock.
 
    Subject to the terms and conditions of the 1997 Stock Option Plan and
applicable law, the Board of Directors or a duly appointed committee thereof
(the "Administrator") has the authority to determine which employees, directors
or consultants should be awarded options, the type of options to be awarded, the
number of shares covered by option awards, the exercise price applicable to
options awarded, the vesting schedule of such options, other terms of the
options and any other matters delegated to it under the 1997 Stock Option Plan
or necessary for the proper administration of the 1997 Stock Option Plan.
Options awarded pursuant to the 1997 Stock Option Plan shall vest and become
exercisable as determined by the Administrator.
 
    Options awarded under the 1997 Stock Option Plan are nontransferable and
generally expire ten years from the date of grant (or, in the case of ISOs
granted to an optionee who owns more than 10% of the total combined voting power
of all classes of stock, five years). Unless otherwise indicated in the Stock
Option Agreement, the vested portion of options awarded pursuant to the 1997
Stock Option Plan generally remain exercisable for three months after the
termination of the optionee's service to the Company. However, if the optionee's
service to the Company ends because of death or disability, unless otherwise
indicated in the Stock Option Agreement, such optionee has 12 months to exercise
the vested portion of his or her options. In addition, pursuant to an amendment
to the 1997 Stock Option Plan duly adopted by the Board of Directors in December
1997, if an employee is terminated without "cause" prior to June 30, 1998, then
all options held by such optionee become immediately vested and exercisable.
 
    The exercise price of options granted under the 1997 Stock Option Plan is
determined by the Administrator at the time of grant, subject to the following
limitations. In the case of ISOs, the exercise price may not be less than 100%
of the fair market value of the Series B Common Stock on the date of grant, and
the exercise price of ISOs granted to an optionee who owns more than 10% of the
total combined voting power of all classes of stock may not be less than 110% of
the fair market value of the Series B Common Stock on the date of grant. In the
case of NQSOs, the exercise price may not be less than 85% of the fair market
value of the Series B Common Stock on the date of grant, and the exercise price
of NQSOs granted to an optionee who owns more than 10% of the total combined
voting power of all classes of stock may not be less than 110% of the fair
market value of the Series B Common Stock on the date of grant.
 
   
    The Board of Directors, acting as Administrator under the 1997 Stock Option
Plan, previously issued options under the plan with exercise prices of $3.00 and
$3.20. In December 1997, the Board of Directors lowered to $3.00 the exercise
prices of options originally issued with an exercise price of $3.20. The
exercise price was reduced in connection with the conclusion of a private
financing, to reflect the Company's determination that the exercise price of
such options was substantially higher than fair market value at that time. In
December 1997 the Company sold shares of Series A Common Stock with 100% warrant
coverage for $3.00, the Company determined that the fair market value of the
Series B Common Stock (which does not possess the super-voting rights of the
Series A Common Stock and which would not be issued with warrant coverage) could
be no greater than $3.00. Accordingly, to continue to incentivize and maintain
good relations with its employees, the Board of Directors determined that
exercise prices should be adjusted to reflect the maximum fair market value of
the Series B Common Stock implied by the
    
 
                                       70

Series A Common Stock financing. As of May 31, 1998, options to purchase an
aggregate of 742,360 shares of Series B Common Stock at an exercise price of
$3.00 were outstanding under the 1997 Stock Option Plan.
    
 
LIMITED LIABILITY AND INDEMNIFICATION
 
    The Company's Certificate of Incorporation (as amended or restated from time
to time, the "Certificate of Incorporation") and bylaws ("Bylaws") provide that
the Company shall, to the fullest extent permitted by Section 145 of the General
Corporation Law of the State of Delaware ("DGCL"), as the same may be amended
and supplemented from time to time, indemnify all directors and officers and all
other persons whom it has authority to indemnify under Section 145 of the DGCL.
 
    FirstWorld has entered into indemnification agreements with its officers and
directors containing provisions which may require FirstWorld, among other
things, to indemnify the 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), and to
advance their expenses incurred as a result of any proceeding against them as to
which they could be indemnified. The Company believes that these provisions and
agreements will assist the Company in attracting and retaining qualified persons
to serve as directors and officers.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Company of expenses incurred or paid by a director, officer
or controlling person of the Company in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer or controlling person
in connection with the Exchange Notes being registered hereunder, the Company
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
    The Company maintains insurance on behalf of its directors and officers,
insuring them against liabilities that they may incur in such capacities or
arising out of such status.

 (1) In accordance with Rule 13d-3 under the Securities and Exchange Act of
     1934, as amended (the "Exchange Act"), a person is deemed to be a
     "beneficial owner" of a security if he or she has or shares the power to
     vote or direct the voting of such security or the power to dispose or
     direct the disposition of such security. A person is also deemed to be a
     beneficial owner of any securities of which that person has the right to
     acquire beneficial ownership within 60 days. More than one person may be
     deemed to be a beneficial owner of the same securities. The percentage
     ownership of each stockholder is calculated based on the total number of
     outstanding shares of Series A Common Stock and Series B Common Stock as of
     May 31, 1998 and those shares of Series A Common Stock or Series B Common
     Stock that may be acquired by such stockholder within 60 days.
     Consequently, the denominator for calculating such percentage may be
     different for each stockholder.
 
 (2) This table is based upon information supplied by directors, executive
     officers and principal stockholders. Unless otherwise indicated in the
     footnotes to this table, each of the stockholders named in this table has
     sole voting and investment power with respect to the shares shown as
     beneficially owned.

     subject to currently exercisable warrants held of record by Spectra 1,
     Spectra 2 and Spectra 3. Beneficial ownership of the foregoing shares is
     attributable to Mr. Sturm because he is the managing member of Spectra 1,
     Spectra 2 and Spectra 3 and is therefore deemed to exercise voting power
     and investment authority with respect to the shares.

     Robert E. and Dianne M. Randall as custodians for Alexandra Dianne Ray
     under CUTMA; beneficial ownership of such shares is attributable to Mr.

     deemed to exercise voting power and investment authority with respect to
     the shares; (c) 280,000 shares of Series B Common Stock held of record by
     Robert E. and Dianne M. Randall as trustees of the Robert E. and Dianne M.
     Randall Family Trust, dated 2/3/97; beneficial ownership of such shares is
     attributable to Mr. Randall because he is a trustee of the Robert E. and

     power and investment authority with respect to the shares; and (d) 16,417
     shares of Series B Common Stock subject to currently exercisable options
     held by Mr. Randall at an exercise price of $3.00.

     Spectra 3, respectively, and therefore may be deemed to be the beneficial

     owner of the shares of Series A Common Stock and Series B Common Stock

      respectively, through a revocable trust of which she is a co-trustee, and

      A Common Stock and Series B Common Stock beneficially owned by such
      entities. Ms. Sturm disclaims beneficial ownership of such shares.

      warrants held by Mr. Lewis at an exercise price of $3.53; (c) 22,017

      record by United Brice Group Ltd., a California corporation. Mr. Saunders

    GENERAL.  On December 30, 1997, the Company completed a private placement of
equity securities to Spectra 3 and Enron (the "Equity Investment"). The Company
issued 5,000,000 shares of newly created Series A Common Stock to each of
Spectra 3 and Enron at an issue price of $3.00 per share pursuant to a Common
Stock Purchase Agreement dated as of December 30, 1997 (the "Stock Purchase
Agreement") by and among the Company, Enron, Spectra 3 and the holders of
$405,500 in principal amount of the Company's convertible subordinated
promissory notes. In addition, the Company issued an aggregate of 135,164 shares
of Series A Common Stock to the holders of the convertible subordinated
promissory notes upon the automatic conversion of the convertible subordinated
promissory notes pursuant to the terms thereof at a conversion price of $3.00
per share. The Company also issued for no additional consideration warrants to
purchase 5,000,000 shares of Series B Common Stock at $3.00 per share to each of
Spectra 3 and Enron and warrants to purchase an aggregate of 135,164 shares of
Series B Common Stock to the holders of the convertible subordinated promissory
notes (collectively, the "Recent Equity Warrants"). Spectra 3, an entity
controlled by Donald L. Sturm, was formed for the purpose of participating in
the Equity Investment. Spectra 3 is an affiliate of Colorado Spectra 1, LLC
("Spectra 1") and Colorado Spectra 2, LLC ("Spectra 2"), entities that owned
equity securities of the Company prior to the Equity Investment. See "Principal
Stockholders." Spectra 1, Spectra 2 and Spectra 3 are referred to herein as the
"Sturm Entities" and Spectra 3, Enron and the holders of the convertible
subordinated promissory notes are referred to herein as the "Purchasers."
 
    The Stock Purchase Agreement also granted Spectra 3 and Enron, for a period
of 45 days following the closing of the Equity Investment, the right to invest
an additional $20,000,000 in the aggregate on the same terms and conditions
applicable to their purchases of Series A Common Stock, except that any
additional shares of Common Stock to be acquired would be Series B Common Stock.
This option was later extended by action of a special committee of the Company's
Board of Directors. Spectra 3 and Enron fully exercised their option to make an
additional $20,000,000 investment concurrently with the closing of the Private
Note Offering.
 
    Substantially concurrently with the Equity Investment, the Company (i)
converted the three existing classes of preferred stock into Series B Common
Stock in accordance with the automatic conversion provision of its existing
charter in order to simplify the Company's capital structure and eliminate the
rights, preferences and privileges of the preferred stock; (ii) amended its
Articles of Incorporation to substantially increase the Company's authorized
capital to allow for the Equity Investment and to provide flexibility for future
financings; and (iii) amended its Articles of Incorporation to designate two
series of Common Stock, with the investors in the Equity Investment to receive
Series A Common Stock and all existing Common Stock (including Common Stock
issued upon conversion of the existing preferred stock) designated as Series B
Common Stock. The Series A Common Stock and Series B Common Stock are identical
in all material respects, except that the Series A Common Stock possess ten
votes per share on all matters subject to a vote of stockholders while the
Series B Common Stock possess one vote per share.
 
    The Recent Equity Warrants are exercisable by the holder thereof in whole or
in part at an exercise price of $3.00 per share at any time following issuance
through the first to occur of (i) the seventh anniversary of the date of
issuance, (ii) the merger of the Company following which the Company's
stockholders own less than 50% of the surviving entity, and (iii) the sale of
all or substantially all of the Company's assets. The exercise price and number
of shares subject to the Recent Equity Warrants are subject to customary
anti-dilution adjustments in the event of a stock split, subdivision,
combination of shares, reorganization or reclassification or in the event that
dividends are paid on the Company's common stock in other securities or assets.
 
    INVESTOR RIGHTS AGREEMENT.  In connection with the closing of the Equity
Investment, the Company entered into an Amended and Restated Investor Rights
Agreement which entitles the Purchasers and
 
                                       75
<PAGE>
certain other prior investors to certain demand and piggyback registration
rights. In addition, the Sturm Entities and Enron were granted rights of first
refusal that permit them to maintain their respective percentage ownership
interest in the Company with respect to future equity issuances. The Sturm
Entities and Enron are the only entities having a right of first refusal or
other preemptive right on future equity financing transactions.
 
    In connection with the Additional Equity Investment, the Company further
amended and restated the Amended and Restated Investor Rights Agreement in order
to (i) allow for, and coordinate with, the registration rights granted to the
Initial Purchasers pursuant to that certain Warrant Registration Rights
Agreement dated as of April 13, 1998 by and between the Company and the Initial
Purchasers and (ii) to make certain other revisions to the previous iteration of
the Amended and Restated Investor Rights Agreement.
 
    AMENDMENT TO STURM WARRANT.  In connection with the Company's Series C
preferred stock financing, the Company and Spectra 1 and Spectra 2 entered into
a Warrant Purchase/Right to Maintain Agreement pursuant to which the Company
issued and sold to Spectra 2 a warrant (the "Sturm Warrant") that was initially
exercisable for 800,000 shares of Common Stock at an aggregate exercise price of
$3,800,000. The Sturm Warrant contained a complex anti-dilution provision
pursuant to which the number of shares purchasable could be increased
significantly based upon the weighted average issuance price of equity
securities issued by the Company prior to the earliest of (i) April 1, 1999,
(ii) the death of Donald L. Sturm and (iii) a public offering of securities by
the Company (the "Adjustment Date"). Based upon those existing provisions, upon
the closing of the Equity Investment, the Sturm Warrant would have been
exercisable for approximately 2,250,000 shares of Common Stock at an aggregate
exercise price of $3,800,000, and assuming exercise of the right of Spectra 3
and Enron to increase their investment by $20 million as described above would
have been exercisable for approximately 2,800,000 shares of Common Stock at an
aggregate exercise price of $3,800,000. The Sturm Warrant would also have
continued to adjust upon future equity issuances through the Adjustment Date.
 
    In connection with the Equity Investment, in order to eliminate the
uncertainty regarding the number of shares purchasable under the Sturm Warrant,
the Company and Spectra 1 and Spectra 2 set the number of shares purchasable
under the Sturm Warrant at 2,110,140 shares of Series B Common Stock with an
exercise price of $1.80 per share (aggregate exercise price of approximately
$3,800,000). The Sturm Warrant, as amended, is subject to customary adjustment
on stock splits, stock dividends, subdivisions or combinations, but would not
otherwise be subject to adjustment. In addition, Spectra 1 and Spectra 2 waived
their maintenance rights provided under the Warrant Purchase/Right to Maintain
Agreement. The Sturm Entities, however, continue to have a right of first
refusal under the Amended and Restated Investor Rights Agreement as described
above.
 
    BOARD OF DIRECTORS.  Upon the closing of the Equity Investment, the
Company's Board of Directors was reconstituted with seven directors as follows:
three designees of the Sturm Entities--Donald L. Sturm, Melanie Sturm and James
O. Spitzenberger; two designees of Enron--C. Kevin Garland and Rodney Malcolm;
one management representative--Robert E. Randall; and John C. Stiska, an
existing director, as an independent member of the Board. Renney Senn and Robert
Cerasoli resigned from the Board at this time. In addition, pursuant to the
Stock Purchase Agreement within six months following the closing of the Equity
Investment, the Board would be further reconstituted to consist of seven
directors, three of whom would be designated by the Sturm Entities, two of whom
would be designated by Enron, one of whom would be designated by the holders of
Series B Common Stock and one of whom would be an independent director. The
right of the Series B stockholders to elect a director is set forth in the
Company's Certificate of Incorporation.
 
    WAIVER OF BUSINESS OPPORTUNITIES.  In an effort to alleviate possible
conflicts of interest among Enron, the Sturm Entities and the Company (and each
of their respective affiliates) with respect to their existing and prospective
businesses, the Company revised its purpose clause in Article II of its
Certificate of
 
                                       76
<PAGE>
Incorporation to provide that the Company generally may not engage in oil,
natural gas, electricity, water and other energy-related business, in lieu of
the general purpose clause that previously had been applicable.
 
    In addition to the restriction on business, the Company, the Sturm Entities
and Enron entered into a Business Opportunity Agreement to address the fact that
Enron and the Sturm Entities or their affiliates own, have agreements with and
otherwise participate in, telecommunications businesses, and may develop,
finance, acquire, enter into agreements with or otherwise participate in, such
businesses in the future, including businesses that are or may become
competitive with the business of the Company. In this regard, Enron advised the
Company and the Sturm Entities that (a) FirstPoint Communications, Inc. and its
affiliates ("FirstPoint"), which are Enron affiliates, are engaged in the
business of providing telecommunications services, and have or may from time to
time develop, finance, acquire, or acquire interests in, telecommunications and
related service and product companies that compete with the Company (including,
without limitation, those that compete in the Company's markets in California)
and (b) FirstPoint was at the time of the investment by Enron in the Company
pursuing a financing, acquisition or investment opportunity in a competitor or
potential competitor of the Company.
 
    The Business Opportunity Agreement generally provides, except to the extent
expressly agreed by the parties and set forth therein, that (i) neither Enron,
the Sturm Entities nor any of their respective affiliates would have any
obligation to pursue any business opportunity jointly with the Company or to
offer any business opportunity to the Company, and any Enron or Sturm Entity
representative on the Board of Directors of the Company would have no obligation
to offer any business opportunity to the Company; (ii) Enron, the Sturm Entities
and their respective affiliates would be free to pursue business opportunities
jointly with parties other than the Company, including opportunities that had
telecommunications applications; and (iii) Enron, the Sturm Entities and their
respective affiliates would be free to compete with the Company and would have
no obligation to the Company to refrain from engaging in any business.
 
    GRANT OF EXCLUSIVE RIGHTS TO ENRON.  The Business Opportunity Agreement also
provides that the Company would, during an "Exclusivity Period" (as defined
below), grant Enron and its affiliates the exclusive right to pursue jointly
with the Company any business opportunity that includes both telecommunications
and utility applications (I.E., the marketing of one or more of natural gas,
electricity or water and the provision of related services, including provision
of the commodity, provision of transmission, transportation or distribution,
provision of financial and risk management services and products, and provision
of customer care functions (E.G., meter, billing and collection functions) (the
"Joint Application Opportunity")). The Exclusivity Period began on the closing
of the Equity Investment and continues until the earlier of (x) the third
anniversary of the date of closing of the Equity Investment or (y) the date upon
which Enron and any of its affiliates hold less than 5% of the capital stock or
warrants of the Company (determined on a fully-diluted basis as if all warrants
or rights to acquire capital stock were exercised, and determined without
reference to any voting rights). During the Exclusivity Period, the Company is
obligated to provide Enron notice of any Joint Application Opportunity that the
Company desires to pursue anywhere in the United States. If Enron notifies the
Company that it desires to participate in the Joint Application Opportunity,
then the Company cannot pursue the Joint Application Opportunity without the
participation of Enron. If Enron elects not to participate in the Joint
Application Opportunity, then the Company is free to pursue independently the
telecommunications portion of such Joint Application Opportunity without the
participation of Enron, but cannot pursue the Joint Application Opportunity with
any other person (except for provision of the telecommunications portion thereof
on a subcontract basis only), and Enron is free to pursue the Joint Application
Opportunity (including the utility applications and/or the telecommunications
applications) on its own or with any party other than the Company.
 
    SECURITYHOLDERS AGREEMENT.  The Sturm Entities and Enron entered into a
Securityholders Agreement, to which the Company is also a party, in connection
with the closing of the Equity Investment. The Securityholders Agreement
contains agreements among the Sturm Entities and Enron with respect to the
designation, election, removal and replacement of the members of the Board of
Directors of the Company
 
                                       77
<PAGE>
other than those elected by the holders of the Company's Series B Common Stock.
The Securityholders Agreement also contains agreements among the Sturm Entities
and Enron (i) providing for rights of first offer with respect to certain
proposed transfers of Common Stock or warrants of the Company by any of the
Sturm Entities or Enron, (ii) providing for rights to purchase the Common Stock
and warrants held by a party to the Securityholders Agreement (other than the
Company) that experiences a change of control or other triggering event and
(iii) providing for rights to participate in certain proposed dispositions of
Common Stock or warrants by any of the Sturm Entities or Enron.
 
    EMPLOYEE SEVERANCE PROGRAM.  In connection with the Equity Investment, the
Company established an employee severance program applicable to any person who
was a full time employee of the Company as of December 1, 1997. The program
provides that if any eligible employee is terminated by the Company without
"cause" (as defined) before June 30, 1998, such employee would receive severance
pay in an amount equal to (i) six months base salary for employees with the
title of director, vice-president or higher, and (ii) two weeks base salary plus
one week base salary for each full year of employment with the Company (with a
minimum of four weeks base salary) for all other eligible employees. The Company
would also pay the base share toward a terminated employee's COBRA benefits,
until the employee accepts other employment for a period of up to nine months
following termination. With respect to such employees with the title of
director, vice-president or higher, the severance payments are subject to a
payment schedule and are conditioned upon execution of a non-competition
agreement.
 
    TRANSACTION FEES AND EXPENSES.  The Company paid the Sturm Entities and
Enron a transaction fee equal to six percent of the gross amount invested by
them in the Equity Investment (based upon the $30 million invested, $900,000 for
the Sturm Entities and $900,000 for Enron). Spectra 3 and Enron also received
the six percent transaction fee on the $20 million invested in the Additional
Equity Investment ($600,000 for the Sturm Entities and $600,000 for Enron). In
addition, the Company reimbursed all reasonable costs and expenses of the Sturm
Entities and Enron incurred in connection with the Stock Purchase Agreement, up
to a maximum of $50,000 for the Sturm Entities and $50,000 for Enron, plus the
$90,000 of required filing fees under the Hart-Scott-Rodino Act.
 
    MANAGEMENT SERVICES AGREEMENTS.  The Company executed Management Services
Agreements with Corporate Managers, LLC, a Colorado limited liability company
and an affiliate of the Sturm Entities, and Enron pursuant to which they will
provide management services to the Company for three years following the closing
of the Equity Investment for an annual management fee. Both Management Services
Agreements initially provided for annual management fees of $500,000 plus out of
pocket expenses. The Company has amended the Management Services Agreement with
Corporate Managers, LLC to provide for an annual management fee of $620,000 plus
out of pocket expenses because Mr. Sturm has taken a more active management role
with the Company than originally anticipated. Corporate Managers, LLC and Enron
each has the right in its discretion to terminate its Management Services
Agreement with the Company.

                         DESCRIPTION OF EXCHANGE NOTES
 
GENERAL
 
    The Exchange Notes will be issued pursuant to an indenture (the "Indenture")
between the Company and The Bank of New York, as trustee (the "Trustee"). The
Exchange Notes will evidence the same indebtedness as the Private Notes (which
they replace) and will be entitled to the benefits of the Indenture. The form
and terms of the Exchange Notes are the same as the form and terms of the
Private Notes except that (i) the Exchange Notes will have been registered under
the Securities Act, and, therefore, the Exchange Notes will not bear legends
restricting the transfer thereof and (ii) Holders of the Exchange Notes will not
be entitled to certain rights of Holders of Private Notes under the Registration
Rights Agreement, which rights will terminate upon the consummation of the
Exchange Offer. The terms of the Exchange Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (the "TIA"), as in effect on the date of the Indenture.
The following summary of the material provisions of the Indenture does not
purport to be complete and is qualified in its entirety by reference to such
agreement, including the definitions therein of certain terms used below. A copy
of the Indenture is available from the Company upon request. The definitions of
certain terms used in the following summary are set forth below under "--Certain
Definitions." As used below in this "Description of Exchange Notes" section, the
term "Company" refers only to FirstWorld Communications, Inc. and not to any of
its Subsidiaries.
 
   
    The Exchange Notes will be senior obligations of the Company, will rank PARI
PASSU in right of payment with all existing and future senior Indebtedness of
the Company and will rank senior in right of payment to any future Subordinated
Indebtedness of the Company, but will be effectively subordinated to any secured
Indebtedness of the Company and future Indebtedness and other liabilities
(including Subordinated Indebtedness and trade payables) of the Company's
Subsidiaries. The Indenture will permit the incurrence of substantial additional
Indebtedness, including secured Indebtedness, by the Company and its
Subsidiaries, subject to certain restrictions. See "Risk Factors--Effective
Subordination of Notes; Holding Company Structure." As of June 30 1998, the
Company had no Subordinated Indebtedness and $7.1 million in outstanding
Indebtedness that ranks PARI PASSU with the Notes. The Notes will not be secured
by any assets and will be effectively subordinated to any existing and future
secured indebtedness of the Company and its Subsidiaries, to the extent of the
value of the assets securing such indebtedness. As of June 30, 1998, the Company
had approximately $243.2 million of outstanding indebtedness. In addition, all
existing and future liabilities (including trade payables) of the Company's
Subsidiaries will be effectively senior to the Notes. See "Risk
Factors--Effective Subordination of Notes; Holding Company Structure." As of
June 30, 1998, the total liabilities of the Company's Subsidiaries was
approximately $28.3 million. Any rights of the Company and its creditors,
including the Holders of Notes, to participate in the assets of any of the
Company's Subsidiaries upon any liquidation or reorganization of any such
subsidiary will be subject to the prior claims of that subsidiary's creditors
(including trade creditors).
    
 
    The operations of the Company are conducted primarily through its
Subsidiaries and the Company is therefore dependent upon the cash flow of its
Subsidiaries to meet its obligations, including its obligations under the Notes.
See "Risk Factors--Effective Subordination of Notes; Holding Company Structure."
 
    As of the date of the Indenture, the Company had six Subsidiaries, each of
which was designated as a Restricted Subsidiary. Under certain circumstances,
the Company will be able to designate Subsidiaries of the Company, including
Subsidiaries that it creates or acquires in the future, to be Unrestricted
Subsidiaries. Unrestricted Subsidiaries will not be subject to many of the
restrictive covenants set forth in the Indenture. See "--Certain
Covenants--Restricted and Unrestricted Subsidiaries."
 
PRINCIPAL, MATURITY AND INTEREST
 
    The Notes are limited in aggregate principal amount at maturity to $470
million and will mature on April 15, 2008. Until the Full Accretion Date, no
interest will accrue or be payable on the Notes, but the
 
                                       79
<PAGE>
Accreted Value will accrete (representing the amortization of original issue
discount) between the date of issuance and the Full Accretion Date, on a
semi-annual bond equivalent basis using a 360-day year comprised of twelve
30-day months such that the Accreted Value shall be equal to the full principal
amount at maturity of the Notes on the Full Accretion Date. Beginning on the
Full Accretion Date, interest on the Notes will accrue at the rate of 13% per
annum and will be payable in cash semi-annually in arrears on April 15 and
October 15 of each year, commencing on October 15, 2003, to Holders of record on
the immediately preceding April 1 and October 1. Interest on the Notes will
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from the Full Accretion Date. Interest will be computed
on the basis of a 360-day year comprised of twelve 30-day months. Principal,
premium, if any, and interest on the Notes will be payable at the office or
agency of the Company maintained for such purpose within the City and State of
New York or, at the option of the Company, payment of interest may be made by
check mailed to the Holders of the Notes at their respective addresses set forth
in the register of Holders of Notes; PROVIDED that all payments of principal,
premium, if any, and interest with respect to Notes of Holders which have given
wire transfer instructions to the Company will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof. Until otherwise designated by the Company, the Company's office or
agency in New York, New York will be the office of the Trustee maintained for
such purpose. The Notes will be issued in denominations of $1,000 and integral
multiples thereof.
 
OPTIONAL REDEMPTION
 
    Except as noted below, the Notes will not be redeemable at the Company's
option prior to April 15, 2003. Thereafter, the Notes will be subject to
redemption at any time at the option of the Company, in whole or in part, in
amounts of $1,000 or integral multiples thereof, upon not less than 30 nor more
than 60 days notice, at the redemption prices (expressed as percentages of
principal amount) set forth below, plus accrued and unpaid interest thereon to
the applicable redemption date, if redeemed during the twelve-month period
beginning on April 15 of the years indicated below:

</TABLE>
 
    In addition, at any time on or prior to April 15, 2001, the Company, at its
option, may use the net cash proceeds (but only to the extent such proceeds
consist of cash or Cash Equivalents) from one or more Public Equity Offerings or
the sale of Capital Stock (other than Disqualified Stock) to one or more
Strategic Investors in a single transaction or a series of related transactions
to redeem up to an aggregate of 35% of the Accreted Value of the Notes at a
redemption price of 113% of the Accreted Value thereof at the time of
redemption, plus accrued and unpaid interest, if any, to the date of redemption;
PROVIDED that at least 65% of the Accreted Value of the Notes originally issued
must remain outstanding immediately after the occurrence of such redemption. In
order to effect the foregoing redemption, the Company must mail a notice of
redemption no later than 30 days after the related Public Equity Offering or
sale of Capital Stock and must consummate such redemption within 60 days of the
closing of such Public Equity Offering or sale of Capital Stock.
 
SELECTION AND NOTICE
 
    If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by
lot or by such method as the Trustee shall deem fair and appropriate; PROVIDED
that no Notes of $1,000 or less shall be
 
                                       80
<PAGE>
redeemed in part. Notices of redemption shall be mailed by first class mail at
least 30 but not more than 60 days before the redemption date to each Holder of
Notes to be redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on Notes or portions of them called for redemption.
 
MANDATORY REDEMPTION
 
    The Company is not required to make mandatory redemption or sinking fund
payments with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
    CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, the Indenture requires the
Company to make an offer to each Holder of Notes to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash (the "Change of Control Payment") equal to 101% of the
aggregate principal amount thereof, plus accrued and unpaid interest thereon to
the date of purchase (or if such Change of Control Offer is prior to the Full
Accretion Date, 101% of the Accreted Value thereof on the date of repurchase).
Within 10 days following any Change of Control, the Company or the Trustee (at
the expense of the Company) will mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Notes on the date specified in such notice, which date shall be no
earlier than 30 days and no later than 60 days from the date such notice is
mailed (the "Change of Control Payment Date"), pursuant to the procedures
required by the Indenture and described in such notice. The Company will comply
with the applicable requirements of Section 14(e) under the Exchange Act and any
other securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the Notes
pursuant to a Change of Control Offer.
 
    On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) irrevocably deposit with the
paying agent for the Notes an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered and (iii) deliver or cause
to be delivered to the Trustee the Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount or Accreted Value, as
applicable, of Notes or portions thereof tendered to the Company and accepted
for payment. The paying agent for the Notes will promptly mail to each Holder of
Notes so tendered the Change of Control Payment for such Notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book-entry)
to each Holder a new Note equal in principal amount at maturity to any
unpurchased portion of the Notes surrendered, if any; provided that each such
new Note will be in a principal amount of $1,000 or an integral multiple
thereof.
 
                                       81
<PAGE>
    ASSET SALES
 
    The Company will not, and will not permit any Restricted Subsidiary to,
consummate an Asset Sale unless (i) the Company or such Restricted Subsidiary,
as the case may be, receives consideration for such Asset Sale at least equal to
the Fair Market Value (as evidenced by a Board Resolution delivered to the
Trustee) of the Property or assets sold or otherwise disposed of; (ii) at least
80% of the consideration received by the Company or such Restricted Subsidiary
for such Property or assets consists of (a) cash, Cash Equivalents, or
Telecommunications Assets; and/or (b) the assumption of Indebtedness of the
Company or such Restricted Subsidiary (other than Indebtedness that is
subordinated to the Notes) and the release of the Company or the Restricted
Subsidiary, as the case may be, from all liability on the Indebtedness assumed;
and (iii) the Company or such Restricted Subsidiary, as the case may be, uses
the Net Cash Proceeds from such Asset Sale in the manner set forth in the next
two paragraphs.
 
    Within 360 days after any Asset Sale, the Company or such Restricted
Subsidiary, as the case may be, may at its option (i) reinvest an amount equal
to the Net Cash Proceeds (or any portion thereof) from such Asset Sale in
Telecommunications Assets or in Voting Stock of any Person engaged in the
Telecommunications Business in the United States (PROVIDED that such Person
concurrently becomes a Restricted Subsidiary of the Company) and/or (ii) apply
an amount equal to such Net Cash Proceeds (or remaining Net Cash Proceeds) to
the permanent reduction of Indebtedness of the Company (other than Indebtedness
to a Restricted Subsidiary) that is senior to or PARI PASSU with the Notes or to
the permanent reduction of Indebtedness or preferred stock of any Restricted
Subsidiary (other than Indebtedness to, or preferred stock owned by, the Company
or another Restricted Subsidiary). Pending the final application of any such Net
Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or
otherwise invest such Net Cash Proceeds in any manner that is not prohibited by
the Indenture. Any Net Cash Proceeds from any Asset Sale that are not used to
reinvest in Telecommunications Assets or in Capital Stock of any Person engaged
in the Telecommunications Business (as described above) and/or to reduce senior
or PARI PASSU Indebtedness of the Company or Indebtedness or preferred stock of
its Restricted Subsidiaries shall constitute "Excess Proceeds."
 
    If at any time the aggregate amount of Excess Proceeds calculated as of such
date exceeds $5 million, the Company shall, within 30 days, use such Excess
Proceeds to make an offer to purchase (an "Asset Sale Offer") on a PRO RATA
basis, from all Holders, Notes in an aggregate principal amount equal to the
maximum principal amount that may be purchased out of Excess Proceeds, at a
purchase price (the "Offer Purchase Price") in cash equal to 100% of the
Accreted Value thereof on any purchase date occurring prior to the Full
Accretion Date, or 100% of the principal amount thereof on any purchase date
occurring on or after the Full Accretion Date, plus accrued and unpaid interest,
if any, to the purchase date, in accordance with the procedures set forth in the
Indenture. Upon completion of an Asset Sale Offer (including payment of the
Offer Purchase Price), any surplus Excess Proceeds that were the subject of such
offer shall cease to be Excess Proceeds, and the Company may then use such
amounts for general corporate purposes.
 
    The Company will comply with the requirements of Section 14(e) under the
Exchange Act and any other securities laws and regulations, to the extent such
laws and regulations are applicable, in connection with the repurchase of Notes
pursuant to an Asset Sale Offer. If the aggregate Accreted Value or principal
amount, as the case may be, of Notes tendered pursuant to such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be
purchased on a pro rata basis.

    LIMITATION ON CONSOLIDATED INDEBTEDNESS
 
    The Company will not, and will not permit any Restricted Subsidiary to,
Incur any Indebtedness (including Acquired Indebtedness) after the Issue Date
unless the ratio of (i) the aggregate consolidated principal amount of
Indebtedness of the Company outstanding as of the most recent available
quarterly or annual balance sheet, after giving PRO FORMA effect to the
Incurrence of such Indebtedness and any other Indebtedness Incurred since such
balance sheet date and the receipt and application of the proceeds thereof, to
(ii) Consolidated Cash Flow Available for Fixed Charges for the four full fiscal
quarters immediately preceding the Incurrence of such Indebtedness for which
consolidated financial statements of the Company have become available,
determined on a PRO FORMA basis as if any such Indebtedness had been Incurred
and the proceeds thereof had been applied at the beginning of such four fiscal
quarters, would be less than 6.0 to 1.0 for such four-quarter periods ending on
or prior to December 31, 2000 and 5.5 to 1.0 for such periods ending thereafter,
after giving PRO FORMA effect to the Incurrence of such Indebtedness and any
other Indebtedness Incurred since such balance sheet date and the receipt and
application of the proceeds thereof.
 
    Notwithstanding the foregoing limitation, the provisions of the preceding
paragraph will not apply to the Incurrence of any of the following items of
Indebtedness, each such item to be given independent effect:

    Subsidiaries of Indebtedness under Senior Credit Facilities in an aggregate
    principal amount outstanding or available at any one time not to exceed $75
    million, and any renewal, extension, refinancing or refunding thereof in an
    amount which, together with any principal amount remaining outstanding or

    immediately prior to such renewal, extension, refinancing or refunding, less
    amounts permanently repaid with proceeds from an Asset Sale;
 
        (ii) the Incurrence by the Company and/or any of its Restricted
    Subsidiaries of Purchase Money Indebtedness and Vendor Financing
    Indebtedness, provided that the aggregate amount of such Purchase Money
    Indebtedness or Vendor Financing Indebtedness Incurred does not exceed 80%
    of the total cost of the Telecommunications Assets financed therewith (or,
    in the case of Vendor Financing Indebtedness, 100% of the total cost of the
    Telecommunications Assets financed therewith if such Vendor Financing
    Indebtedness was extended for the purchase of tangible physical assets and
    was so financed by the vendor thereof or an affiliate of such vendor);
 
       (iii) the Incurrence by the Company and/or any of its Restricted
    Subsidiaries, as applicable, of Indebtedness owed by the Company to any
    Restricted Subsidiary of the Company or Indebtedness owed by a Restricted
    Subsidiary of the Company to the Company or another Restricted Subsidiary of
    the Company; provided that upon (x) the transfer or other disposition by
    such Restricted Subsidiary or the Company of any Indebtedness so permitted
    to a Person other than the Company or another Restricted Subsidiary of the

    lease, transfer or other disposition of shares of Capital Stock (including
    by consolidation or merger) of such Restricted Subsidiary to a Person other
    than the Company or another such Restricted Subsidiary or (z) the
    designation of such Restricted Subsidiary as an Unrestricted Subsidiary, the
    provisions of this clause (iii) shall no longer be applicable to such
    Indebtedness and such Indebtedness shall be deemed to have been Incurred at
    the time of such transfer or other disposition;
 
       (iv) the Incurrence by the Company and/or any of its Restricted
    Subsidiaries of Indebtedness Incurred to renew, extend, refinance or refund

<PAGE>
    outstanding at the date of the Indenture or Purchase Money Indebtedness or
    Vendor Financing Indebtedness Incurred pursuant to clause (ii) of this
    paragraph in an aggregate amount (as determined pursuant to the definition
    of "Indebtedness") not to exceed the aggregate amount of Indebtedness (as so
    determined), and accrued interest on, the Indebtedness so refinanced plus
    the amount of any premium required to be paid in connection with such
    refinancing pursuant to the terms of the Indebtedness so refinanced or the
    amount of any premium reasonably determined by the Company as necessary to
    accomplish such refinancing by means of a tender offer or privately
    negotiated repurchase, plus the reasonable expenses of the Company Incurred
    in connection with such refinancing; PROVIDED that Indebtedness the proceeds
    of which are used to refinance the Notes or Indebtedness which is PARI PASSU
    to the Notes or Indebtedness which is subordinate in right of payment to the
    Notes shall only be permitted under this clause (iv) if (A) in the case of
    any refinancing of the Notes or Indebtedness which is PARI PASSU to the
    Notes, the refinancing Indebtedness is PARI PASSU to the Notes or
    constitutes Subordinated Indebtedness, and, in the case of any refinancing
    of Subordinated Indebtedness, the refinancing Indebtedness constitutes
    Subordinated Indebtedness and (B) in any case, the refinancing Indebtedness
    by its terms, or by the terms of any agreement or instrument pursuant to
    which such Indebtedness is issued, (x) does not provide for payments of
    principal of such Indebtedness at stated maturity or by way of a sinking
    fund applicable thereto or by way of any mandatory redemption, defeasance,
    retirement or repurchase thereof by the Company (including any redemption,
    retirement or repurchase which is contingent upon events or circumstances,
    but excluding any retirement required by virtue of the acceleration of any
    payment with respect to such Indebtedness upon any event of default
    thereunder), in each case prior to the time the same are required by the
    terms of the Indebtedness being refinanced and (y) does not permit
    redemption or other retirement (including pursuant to an offer to purchase
    made by the Company or a Restricted Subsidiary of the Company) of such
    Indebtedness at the option of the holder thereof prior to the time the same
    are required by the terms of the Indebtedness being refinanced, other than a
    redemption or other retirement at the option of the holder of such
    Indebtedness (including pursuant to an offer to purchase made by the Company
    or a Restricted Subsidiary of the Company) which is conditioned upon a
    change of control pursuant to provisions substantially similar to those
    described under "--Repurchase at the Option of Holders--Change of Control;"
 
        (v) the Incurrence by the Company and/or any of its Restricted
    Subsidiaries of Indebtedness consisting of Permitted Interest Rate
    Protection Agreements;
 
        (vi) the Incurrence by the Company and/or any of its Restricted
    Subsidiaries of Indebtedness (A) in respect of performance, surety or appeal
    bonds provided in the ordinary course of business or (B) arising from
    customary agreements providing for indemnification, adjustment of purchase
    price for closing balance sheet changes within 90 days after closing, or
    similar obligations, or from Guarantees or letters of credit, surety bonds
    or performance bonds securing any obligations of the Company or any of its
    Restricted Subsidiaries pursuant to such agreements, in each case Incurred
    in connection with the disposition of any business, assets or Restricted
    Subsidiary of the Company (other than Guarantees of Indebtedness Incurred by
    any Person acquiring all or any portion of such business, assets or
    Restricted Subsidiary of the Company for the purpose of financing such
    acquisition) and in an aggregate principal amount not to exceed the gross
    proceeds actually received by the Company or any Restricted Subsidiary in
    connection with such disposition;
 
       (vii) the Incurrence by the Company of Indebtedness (other than secured
    Acquired Indebtedness) in an aggregate principal amount not to exceed 2.0
    times the sum of the net cash proceeds received by the Company after the
    date of the Indenture in connection with any issuance and sale of Capital
    Stock (other than Disqualified Stock and other than the proceeds of the
    Equity Commitment), PROVIDED that such Indebtedness does not mature prior to
    the Stated Maturity of the Notes or has an Average Life at least equal to
    the Notes; and
 
                                       84
<PAGE>
      (viii) the Incurrence by the Company and/or any of its Restricted
    Subsidiaries of Indebtedness not otherwise permitted to be Incurred pursuant
    to clauses (i) through (vii) above, which, together with any other
    outstanding Indebtedness Incurred pursuant to this clause (viii), has an
    aggregate principal amount not in excess of $10 million at any time
    outstanding.
 
    Notwithstanding any other provision of this "--Certain Covenants--Limitation
on Consolidated Indebtedness" covenant, the maximum amount of Indebtedness that
the Company or a Restricted Subsidiary may Incur pursuant to this "--Certain
Covenants--Limitation on Consolidated Indebtedness" covenant shall not be deemed
to be exceeded due solely as the result of fluctuations in the exchange rates of
currencies.
 
    For purposes of determining any particular amount of Indebtedness under this
"--Certain Covenants--Limitation on Consolidated Indebtedness" covenant (1)
Guarantees, Liens or obligations with respect to letters of credit supporting
Indebtedness otherwise included in the determination of such particular amount
shall not be included and (2) any Liens granted pursuant to the equal and
ratable provisions referred to in the "--Certain Covenants--Limitation on Liens"
covenant described below shall not be treated as Indebtedness. For purposes of
determining compliance with this "--Certain Covenants-- Limitation on
Consolidated Indebtedness" covenant, in the event that an item of Indebtedness
meets the criteria of more than one of the types of Indebtedness described in
the above clauses, the Company, in its sole discretion, shall classify such item
of Indebtedness and only be required to include the amount and type of such
Indebtedness in one of such clauses.
 
    LIMITATION ON RESTRICTED PAYMENTS
 
    The Company will not, and will not permit any of its Restricted Subsidiaries

and after giving effect to such proposed Restricted Payment (i) no Default or
Event of Default shall have occurred and be continuing or shall occur as a

least $1.00 of additional Indebtedness pursuant to the first paragraph of
"--Certain Covenants--Limitation on Consolidated Indebtedness;" and (iii) after
giving effect to such Restricted Payment on a PRO FORMA basis, the aggregate
amount expended (the amount so expended, if other than cash, to be determined in
good faith by a majority of the disinterested members of the Board of Directors,
whose determination shall be conclusive and evidenced by a resolution thereof
filed with the Trustee) or declared for all Restricted Payments after the Issue
Date does not exceed the sum of (A) 50% of the Consolidated Net Income of the

limitation, from Unrestricted Subsidiaries) or from redesignations of
Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as

Person the amount of Investments previously made subsequent to the Issue Date by
the Company or any Restricted Subsidiary in such Person and which was treated as
a Restricted Payment PLUS (C) the aggregate net proceeds (other than proceeds

set forth in clause (ii) of the following paragraph) received after the date of
the Indenture, including the fair value of property other than cash (determined

Directors, whose determination shall be conclusive and evidenced by a resolution
thereof

conversion of Indebtedness of the Company into Capital Stock (other than
Disqualified Stock and other than by a Restricted Subsidiary) of the Company
after the date of the Indenture.

or out of the proceeds of (x) the substantially concurrent sale of Qualified
Stock of the Company or (y) the substantially concurrent Incurrence of
Indebtedness of the Company or any Restricted Subsidiary that (I) is permitted

Company), provided that such new Indebtedness (A) is subordinated in right of
payment to the Notes at least to the same extent as, (B) has an Average Life at

earlier than, any equivalent amount of principal under the Indebtedness so
retired; (iv) making payments or distributions to dissenting stockholders
pursuant to applicable law in connection with a consolidation, merger or

long as such Indebtedness will be so secured or (ii) in the event such

to the Fair Market Value (as evidenced by a Board Resolution delivered to the
Trustee) of the Property subject to such transaction; (ii) the Attributable
Indebtedness of the Company or such Restricted Subsidiary with respect thereto

any manner material to the Company or any Restricted Subsidiary; (g) in the case
of clause (iii) above, restrictions contained in any security agreement
(including a Capital Lease Obligation) securing Indebtedness of the Company or a
Restricted Subsidiary otherwise permitted under the Indenture, but only to the
extent such restrictions restrict the transfer of the property
 
                                       87
<PAGE>
subject to such security agreement and (h) any restriction with respect to a
Restricted Subsidiary of the Company imposed pursuant to an agreement which has
been entered into for the sale or disposition of all or substantially all of the
Capital Stock or assets of such Restricted Subsidiary, provided that the
consummation of such transaction would not result in an Event of Default or an
event that, with the passing of time or the giving of notice or both, would
constitute an Event of Default, that such restriction terminates if such
transaction is not consummated and that the consummation or abandonment of such
transaction occurs within one year of the date such agreement was entered into.
 
    Nothing contained in this "--Certain Covenants--Limitation on Dividend and
Other Payment Restrictions Affecting Restricted Subsidiaries" covenant shall
prevent the Company or any other Restricted Subsidiary from (1) creating,
Incurring, assuming or suffering to exist any Liens otherwise permitted under

permitted under "--Certain Covenants--Limitation on Restricted Payments" if made
on the date of such issuance and (ii) shall not permit any Person other than the
Company or a Restricted Subsidiary to own any Capital Stock of any Restricted
Subsidiary, other than directors' qualifying shares except for a sale of 100% of

enter into any contract, agreement, understanding, loan, advance or Guarantee
with or for the benefit of, any Affiliate (each of the foregoing, an "Affiliate
Transaction"), unless (a) such Affiliate Transaction or series of related
Affiliate Transactions is on terms that are no less favorable to the Company or
such Restricted Subsidiary than those that would have been obtained in a
comparable arms-length transaction by the Company or such Restricted Subsidiary
with a Person that is not an Affiliate (or, in the event that there are no
comparable transactions involving Persons who are not Affiliates of the Company
or the relevant Restricted Subsidiary to apply for comparative purposes, is
otherwise on terms that, taken as a whole, the Company has determined to be fair
to the Company or the relevant Restricted Subsidiary) and (b) the Company
delivers to the Trustee (i) with respect to any Affiliate Transaction or series
of related Affiliate Transactions involving aggregate payments in excess of $1
million, a Board Resolution certifying that such Affiliate Transaction or series

Affiliate Transaction or series of related Affiliate Transactions has been
approved by a majority of the disinterested members of the Board of Directors
who have determined that such Affiliate Transaction or series of related
Affiliate Transactions is in the best interest of the Company or such Restricted
Subsidiary and (ii) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate payments in excess of $10
million, a written opinion from an investment banking firm of national standing
in the United States which, in the good faith judgment of the Board of
Directors, is independent with respect to the Company and its Subsidiaries and
qualified to perform such task; PROVIDED that the following shall not be deemed
Affiliate Transactions: (i) any employment agreement entered into by the Company
or any of its Restricted Subsidiaries in the ordinary course of business and
 
                                       88
<PAGE>
consistent with industry practice; (ii) any agreement or arrangement with

Board of Directors and consistent with industry practice; (iii) transactions
between or among the Company and its Restricted Subsidiaries; (iv) transactions
permitted by the covenant described under "--Certain Covenants--Limitation on
Restricted Payments"; and (v) transactions pursuant to the Management Services
Agreements described under "Certain Transactions," as in effect on the Issue
Date.
 
    LIMITATIONS ON ISSUANCES OF GUARANTEES OF INDEBTEDNESS
 
    The Indenture provides that the Company will not permit any Subsidiary,
directly or indirectly, to Guarantee, assume or in any other manner become
liable with respect to any Pari Passu Indebtedness or Subordinated Indebtedness
of the Company unless such Subsidiary simultaneously executes and delivers a
supplemental indenture to the Indenture providing for a Guarantee of the Notes
on the same terms as the Guarantee of such Indebtedness; PROVIDED that (i) such
Guarantee need not be secured unless required pursuant to "Limitation on Liens"
and (ii) if such Indebtedness is by its terms expressly subordinated to the
Notes, any such assumption, Guarantee or other liability of such Subsidiary with
respect to such Indebtedness shall be subordinated to such Subsidiary's
Guarantee of the Notes at least to the same extent as such Indebtedness is
subordinated to the Notes. This paragraph shall not apply to any Guarantee or
assumption of liability of Indebtedness permitted under the Indenture described
in clauses (i), (iv), (v) and (vi) of the second paragraph under "--Limitation
on Consolidated Indebtedness."
 
    Notwithstanding the foregoing, any Guarantee by a Subsidiary of the Notes
shall provide by its terms that it (and all Liens securing the same) shall be
automatically and unconditionally released and discharged upon any sale,
exchange or transfer, to any Person not an Affiliate of the Company, of all or
substantially all of the assets of such Subsidiary or all of the Capital Stock
of such Subsidiary owned by the Company, which transaction is in compliance with
the terms of the Indenture and such Subsidiary is released from its Guarantees
of other Indebtedness of the Company or any of its Subsidiaries.
 
    RESTRICTED AND UNRESTRICTED SUBSIDIARIES
 
    (a) The Company may designate a Subsidiary (including a newly formed or
newly acquired Subsidiary) of the Company or any of its Restricted Subsidiaries
as an Unrestricted Subsidiary so long as (A) such Subsidiary (i) does not have
any obligations which, if in Default, would result in a cross default on
Indebtedness of the Company or a Restricted Subsidiary (other than Indebtedness
to the Company or a Restricted Subsidiary), (ii) is not party to any agreement,
contract, arrangement or understanding with the Company or any Restricted
Subsidiary of the Company unless the terms of any such agreement, contract,
arrangement or understanding are no less favorable to the Company or such
Restricted Subsidiary than those that might be obtained at the time from Persons
who are not Affiliates of the Company, unless such agreement, contract,
arrangement or understanding constitutes a Restricted Payment permitted by the
Indenture; (iii) is a Person with respect to which neither the Company nor any
of its Restricted Subsidiaries has any direct or indirect obligation (x) to
subscribe for additional Equity Interests or (y) to maintain or preserve such
Person's financial condition or to cause such Person to achieve any specified
levels of operating results; (iv) has not Guaranteed or otherwise directly or
indirectly provided credit support for any Indebtedness of the Company or any of
its Restricted Subsidiaries; (v) has at least one director on its board of
directors that is not a director or executive officer of the Company or any of

director or executive officer of the Company or any of its Restricted
Subsidiaries, (vi) such Subsidiary does not own any Telecommunications Assets
that are essential to the operation of the Company's business, taken as a whole
and (vii) one of the following is true: (x) such Subsidiary has total assets of
$1,000 or less, (y) such Subsidiary has assets of more than $1,000 and an

effective immediately upon such Person becoming a
 
                                       89
<PAGE>
Subsidiary; and (B) no Default or Event of Default would occur as a result of
such designation. Unless so designated as an Unrestricted Subsidiary, any Person
that becomes a Subsidiary of the Company or any of its Restricted Subsidiaries
shall be classified as a Restricted Subsidiary thereof.
 
    (b) The Company will not, and will not permit any of its Restricted
Subsidiaries to, take any action or enter into any transaction or series of
related transactions that would result in a Person (other than a newly formed
Subsidiary having no outstanding Indebtedness (other than Indebtedness to the
Company or a Restricted Subsidiary) at the date of determination) becoming a
Restricted Subsidiary (whether through an acquisition, the redesignation of an
Unrestricted Subsidiary or otherwise) unless, after giving effect to such
action, transaction or series of related transactions, on a pro forma basis, (i)
the Company could Incur at least $1.00 of additional Indebtedness pursuant to
"--Certain Covenants--Limitation on Consolidated Indebtedness" and (ii) no

as of the date specified in such Board Resolution, which shall not be prior to
the date such Board Resolution is delivered to the Trustee.
 
    BUSINESS ACTIVITIES
 
    The Indenture provides that the Company and its Restricted Subsidiaries may
not, directly or indirectly, engage in any business other than the
Telecommunications Business.
 
    PAYMENTS FOR CONSENT
 
    The Indenture provides that neither the Company nor any of its Affiliates
shall, directly or indirectly, pay or cause to be paid any consideration,
whether by way of interest, fee or otherwise, to any Holder of any Notes for or
as an inducement to any consent, waiver or amendment of any of the terms or
provisions of the Indenture or the Notes unless such consideration is offered to
be paid or agreed to be paid to all Holders of the Notes that consent, waive or
agree to amend in the time frame set forth in the solicitation documents
relating to such consent, waiver or agreement.
 
    REPORTS
 
    The Indenture provides that, whether or not required by the rules and
regulations of the Commission, so long as any Notes are outstanding, the Company
will furnish to the Holders of Notes and file with the Commission (i) all
quarterly and annual financial information that would be required to be
contained in a filing with the Commission on Forms 10-Q and 10-K if the Company
were required to file such forms, including a "Management's Discussion and
Analysis of Financial Condition and Results of Operations" that describes the
financial condition and results of operations of the Company and its
consolidated Subsidiaries (showing in reasonable detail, either on the face of
the financial statements or in the footnotes thereto and in Management's
Discussion and Analysis of Financial Condition and Results of Operations, the
financial condition and results of operations of the Company and its Restricted
Subsidiaries separate from the financial condition and results of operations of
the Unrestricted Subsidiaries of the Company) and, with respect to the annual
information only, a report thereon by the Company's certified independent
accountants and (ii) all current reports that would be required to be filed with
the Commission on Form 8-K if the Company were required to file such reports, in
each case within the time periods specified in the Commission's rules and
regulations. In addition, for so long as any Notes are outstanding, the Company
will furnish to the Holders of the Notes, securities analysts and prospective
investors or beneficial owners of the Notes, upon their request, the information
required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

CONSOLIDATION, MERGER, CONVEYANCE, LEASE OR TRANSFER
 
    The Company will not, in any transaction or series of related transactions,
consolidate with, or merge with or into, any other Person (other than a merger
of a Restricted Subsidiary into the Company in which the Company is the
continuing corporation), or sell, convey, assign, transfer, lease or otherwise
dispose of all or substantially all of the Property and assets of the Company
and the Restricted Subsidiaries taken as a whole to any other Person, unless:

    assignment, conveyance, transfer, lease or disposition, all or substantially
    all of the Property and assets of the Company and the Restricted
    Subsidiaries taken as a whole (such corporation or Person, the "Surviving
    Entity"), shall be a corporation organized and validly existing under the
    laws of the United States of America, any state thereof or the District of
    Columbia, and shall expressly assume, by a supplemental indenture, the due

    any Indebtedness Incurred in connection with or in respect of such
    transaction or series of related transactions), no Event of Default or
    Default shall have occurred and be continuing;
 
       (iii) immediately after giving effect to such transaction or series of
    related transactions on a PRO FORMA basis (including, without limitation,

    transaction or series of related transactions), the Company (or the
    Surviving Entity, if the Company is not continuing) would (A) be permitted
    to Incur at least $1.00 of additional Indebtedness pursuant to the first
    paragraph of "--Certain Covenants--Limitation on Consolidated Indebtedness"
    and (B) have a Consolidated Net Worth that is not less than the Consolidated
    Net Worth of the Company immediately before such transaction or series of
    related transactions; and
 
        (iv) if, as a result of any such transaction, Property of the Company
    would become subject to a Lien prohibited by the provisions of the Indenture
    described under "--Certain Covenants--Limitation on Liens" above, the
    Company or the successor entity shall have secured the Notes as required
    thereby.
 
EVENTS OF DEFAULT
 
    Each of the following is an "Event of Default" under the Indenture:

        (c) the Company or any of its Restricted Subsidiaries fails to comply

        (f) the entry by a court of competent jurisdiction of one or more final
    judgments against the Company or any Restricted Subsidiary in an uninsured

    discharged, waived, stayed, bonded or satisfied for a period of 45
    consecutive days;
 
        (g) the entry by a court having jurisdiction in the premises of (i) a

    constituted, or any other applicable Federal, state or foreign bankruptcy,
    insolvency or similar law, or appointing a custodian, receiver, liquidator,
    assignee, trustee, sequestrator or other similar official of the Company or
    any Restricted Subsidiary or of any substantial part of the Property or
    assets of the Company or any Restricted Subsidiary, or ordering the winding
    up or liquidation of the affairs of the Company or any Restricted
    Subsidiary, and the continuance of any such decree or order for relief or
    any such other decree or order unstayed and in effect for a period of 45
    consecutive days; or
 
        (h) (i) the commencement by the Company or any Restricted Subsidiary of
    a voluntary case or proceeding under U.S. bankruptcy laws, as now or
    hereafter constituted, or any other applicable Federal, state or foreign
    bankruptcy, insolvency or other similar law or of any other case or
    proceeding to be adjudicated a bankrupt or insolvent; or (ii) the consent by
    the Company or any Restricted Subsidiary to the entry of a decree or order
    for relief in respect of the Company or any Restricted Subsidiary in an
    involuntary case or proceeding under U.S. bankruptcy laws, as now or
    hereafter constituted, or any other applicable Federal, state or foreign
    bankruptcy, insolvency or other similar law or to the commencement of any
    bankruptcy or insolvency case or proceeding against the Company or any
    Restricted Subsidiary; or (iii) the filing by the Company or any Restricted
    Subsidiary of a petition or answer or consent seeking reorganization or
    relief under U.S. bankruptcy laws, as now or hereafter constituted, or any
    other applicable Federal, state or foreign bankruptcy, insolvency or other
    similar law; or (iv) the consent by the Company or any Restricted Subsidiary
    to the filing of such petition or to the appointment of or taking possession
    by a custodian, receiver, liquidator, assignee, trustee, sequestrator or

    or any Restricted Subsidiary in writing of its inability to pay its debts
    generally as they become due; or (vi) the taking of corporate action by the
    Company or any Restricted Subsidiary in furtherance of any such action.
 
    If any Event of Default (other than an Event of Default specified in clause
(g) or (h) above) occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% of the outstanding aggregate
principal amount of Notes may declare the Default Amount (as defined below) and
any accrued and unpaid interest on all Notes then outstanding to be immediately
due and payable by a
 
                                       92
<PAGE>
notice in writing to the Company (and to the Trustee if given by Holders of the
Notes), and upon any such declaration, such Default Amount and any accrued
interest will become and be immediately due and payable. If any Event of Default
specified in clause (g) or (h) above occurs, the Default Amount and any accrued
and unpaid interest on the Notes then outstanding shall become immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holder of Notes. Until the Full Accretion Date, the "Default Amount" shall
equal the Accreted Value of the Notes as of such date. On or after the Full
Accretion Date, the "Default Amount" shall equal 100% of the principal amount
thereof. Under certain circumstances, the Holders of a majority in principal
amount of the outstanding Notes by notice to the Company and the Trustee may
rescind an acceleration and its consequences.
 
    In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to April
15, 2003 by reason of any willful action (or inaction) taken (or not taken) by
or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to such date, then the premium specified in the
Indenture shall also become immediately due and payable to the extent permitted
by law upon the acceleration of the Notes.
 
    The Company will be required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required within 30
days after becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement describing such Default or Event of Default, its status and
what action the Company is taking or proposes to take with respect thereto. The
Trustee may withhold from Holders of the Notes notice of any continuing Default
or Event of Default (other than relating to the payment of principal or
interest) if the Trustee determines that withholding such notice is in the
Holders' interest.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
    The Company and the Trustee may, at any time and from time to time, without
notice to or consent of any Holder of Notes, enter into one or more indentures
supplemental to the Indenture (1) to evidence the succession of another Person
to the Company and the assumption by such successor of the covenants of the
Company in the Indenture and the Notes; (2) to add to the covenants of the
Company, for the benefit of the Holders, or to surrender any right or power
conferred upon the Company by the Indenture; (3) to add any additional Events of
Default; (4) to provide for uncertificated Notes in addition to or in place of
certificated Notes; (5) to evidence and provide for the acceptance of
appointment under the Indenture of a successor Trustee; (6) to secure the Notes;
(7) to cure any ambiguity in the Indenture, to correct or supplement any
provision in the Indenture which may be inconsistent with any other provision
therein or to add any other provisions with respect to matters or questions
arising under the Indenture; PROVIDED such actions shall not adversely affect
the interests of the Holders in any material respect; or (8) to comply with the
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the TIA
 
    With the consent of the Holders of not less than a majority in principal
amount of the outstanding Notes, the Company and the Trustee may enter into one
or more indentures supplemental to the Indenture for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or modifying in any manner the rights of the Holders; provided
that no such supplemental indenture shall, without the consent of the Holder of
each outstanding Note: (1) change the Stated Maturity of the principal of, or
any installment of interest on, any Note, or alter the redemption provisions
thereof, or reduce the principal amount thereof (or premium, if any), or the
interest thereon that would be due and payable upon Maturity thereof, or change
the place of payment where, or the coin or currency in which, any Note or any
premium or interest thereon is payable, or impair the right to
 
                                       93
<PAGE>
institute suit for the enforcement of any such payment on or after the maturity
thereof; (2) reduce the percentage in principal amount of the outstanding Notes,
the consent of whose Holders is necessary for any such supplemental indenture or
required for any waiver of compliance with certain provisions of the Indenture
or certain Defaults thereunder; (3) subordinate in right of payment, or
otherwise subordinate, the Notes to any other Indebtedness; (4) modify any
provision of the Indenture relating to the calculation of Accreted Value; or (5)
modify any provision described in this paragraph (except to increase any
percentage set forth herein).
 
    The Holders of not less than a majority in principal amount of the
outstanding Notes may, on behalf of the Holders of all the Notes, waive any past
Default under the Indenture and its consequences, except a Default (1) in the
payment of the principal of (or premium, if any) or interest on any Note, or (2)
in respect of a covenant or provision hereof which under the proviso to the
prior paragraph cannot be modified or amended without the consent of the Holder
of each outstanding Note affected.
 
SATISFACTION AND DISCHARGE OF THE INDENTURE; DEFEASANCE
 
    The Company may terminate its obligations under the Indenture when (i)
either (A) all outstanding Notes have been delivered to the Trustee for
cancellation or (B) all such Notes not theretofore delivered to the Trustee for
cancellation have become due and payable, will become due and payable within one
year or are to be called for redemption within one year under irrevocable
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name and at the expense of the Company, and the Company
has irrevocably deposited or caused to be deposited with the Trustee funds in an
amount sufficient to pay and discharge the entire indebtedness on the Notes not
theretofore delivered to the Trustee for cancellation, for principal of (or
premium, if any, on) and interest to the date of deposit or maturity or date of
redemption; (ii) the Company has paid or caused to be paid all sums payable by
the Company under the Indenture; and (iii) the Company has delivered an
Officers' Certificate and an Opinion of Counsel relating to compliance with the
conditions set forth in the Indenture.
 
    The Company, at its election, shall (a) be deemed to have paid and
discharged its debt on the Notes and the Indenture shall cease to be of further
effect as to all outstanding Notes (except as to (i) rights of registration of
transfer, substitution and exchange of Notes and the Company's right of optional
redemption, (ii) rights of Holders to receive payments of principal of, premium,
if any, and interest on the Notes (but not the Change of Control Purchase Price
or the Offer Purchase Price) and any rights of the Holders with respect to such
amounts, (iii) the rights, obligations and immunities of the Trustee under the
Indenture and (iv) certain other specified provisions in the Indenture) or (b)
cease to be under any obligation to comply with certain restrictive covenants
including those described under "--Certain Covenants," after the irrevocable
deposit by the Company with the Trustee, in trust for the benefit of the
Holders, at any time prior to the maturity of the Notes, of (A) money in an
amount, (B) U.S. Government Obligations which through the payment of interest
and principal will provide, not later than one day before the due date of
payment in respect of the Notes, money in an amount, or (C) a combination
thereof, sufficient in the opinion of a nationally recognized firm of
independent public accountants, to pay and discharge the principal of, and
interest on, the Notes then outstanding on the dates on which any such payments
are due in accordance with the terms of the Indenture and of the Notes. Such
defeasance or covenant defeasance shall be deemed to occur only if certain
conditions are satisfied, including, among other things, delivery by the Company
to the Trustee of an opinion of counsel reasonably acceptable to the Trustee to
the effect that (i) such deposit, defeasance and discharge will not be deemed,
or result in, a taxable event for federal income tax purposes with respect to
the Holders; and (ii) the Company's deposit will not result in the Trust or the
Trustee being subject to regulation under the Investment Company Act of 1940.

<PAGE>
THE TRUSTEE
 
    The Bank of New York is the Trustee under the Indenture.
 
    The Holders of not less than a majority in principal amount of the
outstanding Notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the Trustee,
subject to certain exceptions. Except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indenture. The Indenture provides that in case an Event of Default shall
occur (which shall not be cured or waived), the Trustee will be required, in the
exercise of its rights and powers under the Indenture, to use the degree of care
of a prudent person in the conduct of such person's own affairs. Subject to such
provisions, the Trustee will be under no obligation to exercise any of its
rights or powers under the Indenture at the request of any of the Holders of the
Notes, unless such Holders shall have offered to the Trustee indemnity
satisfactory to it against any loss, liability or expense.
 
NO PERSONAL LIABILITY OF CONTROLLING PERSONS, DIRECTORS, OFFICERS, EMPLOYEES AND
  STOCKHOLDERS
 
    No controlling Person, director, officer, employee, incorporator or
stockholder of the Company, as such, shall have any liability for any covenant,
agreement or other obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of, or by reason of, such obligations or
their creation, solely by reason of its past, present or future status as a
controlling Person, director, officer, employee, incorporator or stockholder of
the Company. By accepting a Note each Holder waives and releases all such
liability (but only such liability). The waiver and release are part of the
consideration for issuance of the Notes. Nonetheless, such waiver may not be
effective to waive liabilities under the federal securities laws and it has been
the view of the Commission that such a waiver is against public policy.
 
CERTAIN DEFINITIONS
 
    Set forth below are certain defined terms used in the Indenture. Reference
is made to the Indenture for a full disclosure of all such terms, as well as any
other capitalized terms used herein for which no definition is provided.
 
    "ACCRETED VALUE" is defined to mean, for any date of calculation, the amount
calculated pursuant to (i), (ii), (iii) or (iv) for each $1,000 of principal
amount at maturity of Notes:
 
        (i) if such date of calculation occurs on one or more of the following
    dates (each a "Semi-Annual Accrual Date"), the Accreted Value will equal the

                         BOOK-ENTRY; DELIVERY AND FORM
 
    The Exchange Notes will initially be represented by one or more permanent
global notes in definitive, fully registered form without interest coupons (each
a "Global Note") and will be deposited with the Trustee as custodian for, and
registered in the name of, Cede & Co., as nominee of the Depositary.
 
    Except as set forth below regarding "Certificated Notes," owners of
beneficial interests in the Global Note(s) will not be entitled to receive
physical delivery of Certificated Notes (as defined below).
 
    The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the "Participants"
or the "Depositary's Participants") and to facilitate the clearance and
settlement of transactions in such securities between Participants through
electronic book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers, banks and trust companies,
clearing corporations and certain other organizations. Access to the
Depositary's system is also available to other entities such as banks, brokers,
dealers and trust companies (collectively, the "Indirect Participants" or the
"Depositary's Indirect Participants") that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly. Persons who are
not Participants may beneficially own securities held by or on behalf of the
Depositary only through the Depositary's Participants or the Depositary's
Indirect Participants.
 
    The Company expects that pursuant to procedures established by the
Depositary (i) upon deposit of the Global Note(s), the Depositary will credit
the accounts of Participants designated by the Exchange Agent with portions of
the principal amount of the Global Note(s) and (ii) ownership of the Notes
evidenced by the Global Note(s) will be shown on, and the transfer of ownership
thereof will be effected only through, records maintained by the Depositary
(with respect to the interests of the Depositary's Participants), the
Depositary's Participants and the Depositary's Indirect Participants. Holders of
Notes are advised that 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 Notes evidenced by the Global Note(s) will be limited to
such extent.
 
    So long as the holder of the Global Note(s) is the registered owner of any
Notes, the holder of the Global Note(s) will be considered the sole holder under
the Indenture of any Notes evidenced by the Global Note(s). Beneficial owners of
Notes evidenced by the Global Note(s) under the Indenture will not be considered
the owners or holders thereof under the Indenture for any purpose, including
with respect to the giving of any directions, instructions or approvals to the
Trustee thereunder. Neither the Company nor the Trustee will have any
responsibility or liability for any aspect of the records of the Depositary or
for maintaining, supervising or reviewing any records of the Depositary relating
to the Notes.
 
    Payments in respect of the principal of, premium, if any, and interest on
any Notes registered in the name of the holder of the Global Note(s) on the
applicable record date will be payable by the Trustee to or at the direction of
the holder of the Global Note(s) in its capacity as the registered holder under
the Indenture. Under the terms of the Indenture, the Company and the Trustee may
treat the persons in whose names Notes, including the Global Note(s), are
registered as the owners thereof for the purpose of receiving such payments.
Consequently, neither the Company nor the Trustee has or will have any
responsibility or liability for the payment of such amounts to beneficial owners
of Notes. The Company believes, however, that it is currently the policy of the
Depositary to immediately credit the accounts of the relevant Participants with
such payments, in amounts proportionate to their respective holdings of
beneficial interests in the Notes as shown on the records of the Depositary.
Payments by the Depositary's Participants and the Depositary's Indirect
Participants to the beneficial owners of Notes will be governed by standing
instructions and customary practice and will be the responsibility of the
Depositary's Participants or the Depositary's Indirect Participants.
 
                                      108
<PAGE>
CERTIFICATED NOTES
 
    Subject to certain conditions, any person having a beneficial interest in
the Global Note(s) may, upon request to the trustee, exchange such beneficial
interest for Notes in registered form without interest coupons ("Certificated
Notes"). Upon any such issuance, the Trustee is required to register such
Certificated Notes in the name of, and cause the same to be delivered to, such
person or persons (or the nominee of any thereof). If (i) the Company notifies
the Trustee in writing that the Depositary is no longer willing or able to act
as a depositary and the Company is unable to locate a qualified successor within
90 days or (ii) the Company, at its option, notifies the Trustee in writing that
it elects to cause the issuance of Notes in the form of Certificated Notes under
the Indenture, then, upon surrender by the holder of Global Note(s) of its
Global Note(s), Certificated Notes will be issued to each person that the holder
of Global Note(s) and the Depositary identify as being the beneficial owner of
the related Notes.
 
    Neither the Company nor the Trustee will be liable for any delay by the
holder of Global Note(s) or the Depositary in identifying the beneficial owners
of Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the holder of the Global Note(s) or
the Depositary for all purposes.
 
SAME DAY SETTLEMENT AND PAYMENT
 
    The Indenture requires that payments in respect of the Notes represented by
the Global Note(s) (including principal, premium, if any, and interest, if any)
be made by wire transfer of immediately available funds to the accounts
specified by the holder of the Global Note(s). With respect to Certificated
Notes, the Company will make all payments of principal, premium, if any,
interest, if any, by wire transfer of immediately available funds to the
accounts specified by the holders thereof or, if no such account is specified,
by mailing a check to each such holder's registered address. The Notes
represented by the Global Note(s) are expected to trade in the Depositary's Same
Day Funds Settlement System, and any permitted secondary market trading activity
in such Notes will therefore be required by the Depositary to be settled in
immediately available funds. The Company expects that secondary trading in the
Certificated Notes will also be settled in immediately available funds.
 
                          DESCRIPTION OF CAPITAL STOCK
 
   
    The authorized capital stock of the Company consists of: (i) 100,000,000
shares of Common Stock and (ii) 10,000,000 shares of preferred stock, $.0001 par
value per share. Of the authorized Common Stock, 10,135,164 shares have been
designated Series A Common Stock and 89,864,836 have been designated Series B
Common Stock. As of June 30, 1998, no shares of preferred stock, 10,135,164
shares of Series A Common Stock, 15,913,208 shares of Series B Common Stock and
warrants to purchase 25,188,021 shares of Series B Common Stock were issued and
outstanding.
    
 
COMMON STOCK
 
    Except as otherwise required by law, actions taken at the Company's
stockholder meetings require the affirmative vote of a majority of the shares
represented at the meeting and that a quorum be present. Other than the right of
first refusal held by Enron and the Sturm Entities described elsewhere herein,
the holders of Common Stock have no preemptive rights. See "Certain
Transactions--Investor Rights Agreement." In the event of a liquidation,
dissolution or winding up of the Company, holders of Common Stock are entitled
to share ratably in the assets of the Company which are legally available for
distribution, if any, remaining after the payment of all debts and liabilities
of the Company and the liquidation preference of any then outstanding preferred
stock. At present there is no established market for the Company's Common Stock.
 
    SERIES A COMMON STOCK.  Each share of the Company's Series A Common Stock
entitles the holder thereof to ten votes on all matters submitted to a vote of
stockholders. Each share of Series A Common
 
                                      109
<PAGE>
Stock is convertible at any time and from time to time at the option of the
holder thereof into one share of Series B Common Stock in accordance with the
terms of the Company's Certificate of Incorporation. In addition, (i) upon a
sale or transfer of any Series A Common Stock to anyone other than (A) a natural
person who is qualified as an accredited investor under applicable securities
laws and who is a member, manager or officer of Spectra 3 or an affiliate of any
such member, manager or officer (a "Permitted Transferee") or (B) an affiliate
of Donald L. Sturm or Enron, or (ii) with respect to shares of Series A Common
Stock held by Spectra 3, upon a transfer of a controlling interest in Spectra 3
to any person or entity other than Enron, Donald L. Sturm, a Permitted
Transferee or one of their affiliates, each share of Series A Common Stock
automatically converts into one share of Series B Common Stock. Spectra 3 and
Enron, the two principal holders of Series A Common Stock, are parties to the
Securityholders Agreement, which, among other things, contains agreements with
respect to the designation, election, removal and replacement of the members of
the Company's Board of Directors other than the director elected by the holders
of the Company's Series B Common Stock. See "Certain
Transactions--Securityholders Agreement."
 
    SERIES B COMMON STOCK.  Each share of Series B Common Stock of the Company
entitles the holder thereof to one vote on all matters submitted to a vote of
stockholders. From and after July 1, 1998, the holders of Series B Common Stock
voting as a class will be entitled to elect one director of the Company at each
meeting called for the election of directors. Any vacancy occurring because of
the death, resignation or removal of a director elected by holders of Series B
Common Stock shall be filled by the vote or written consent of a majority of the
shares of Series B Common Stock or, in the absence of such action by the holders
of Series B Common Stock, by the action of the remaining directors then in
office. All other directors shall be elected by the holders of Series A Common
Stock and Series B Common Stock voting together.
 
PREFERRED STOCK
 
    The preferred stock may be issued from time to time in one or more series.
Subject to limitations imposed by the Certificate of Incorporation of the
Company, the Board of Directors has the authority to fix the number of shares of
each such series, determine the designation thereof and to determine or alter
the rights, preferences and restrictions imposed upon any unissued series of
preferred stock. The issuance of preferred stock in the future could adversely
affect the rights of the holders of Common Stock. For example, an issuance of
preferred stock could result in a class of securities outstanding with
preferences over the common stock with respect to liquidations.
 
   
WARRANTS ISSUED IN CONNECTION WITH THE PRIVATE NOTE OFFERING
    
 
   
    In the Private Note Offering the Company sold 470,000 units (the "Units"),
each Unit consisting of $1,000 principal amount at maturity of Private Notes and
a warrant to purchase 7.9002 shares of the Company's Series B Common Stock

Company's Series B common stock or (iii) in the event of a Change of Control of
the Company, and expire on April 15, 2008. Pursuant to the terms thereof, the
separation of the Private Note Warrants from the Private Notes occurred on July
11, 1998, 90 days after April 13, 1998 (the date of issuance of the Units). The
Private Note Warrants have the registration rights set forth below under the
caption "--Registration Rights." The Private Note Warrants are currently held of
record by one owner.

REGISTRATION RIGHTS
 
    Several agreements provide registration rights to certain of the Company's
investors.
 
    THE INVESTOR RIGHTS AGREEMENT.  The Amended and Restated Investor Rights
Agreement grants certain demand and "piggyback" registration rights to the Sturm
Entities, Enron and certain other investors. Subject to certain exceptions and
requirements, the parties to the Amended and Restated Investor Rights Agreement
are entitled to demand three long-form registrations; provided, however, that
the Company is not required to effect demand registrations prior to the earlier
to occur of January 31, 2000 or the Company's first firm commitment underwritten
public offering of its Series B Common Stock. In addition, subject to certain
exceptions and requirements, the parties to the Amended and Restated Investor
Rights Agreement are entitled to demand unlimited short-form registrations once
such short-form registration becomes available to the Company. The parties to
the Amended and Restated Investor Rights Agreement also possess "piggyback"
registration rights which entitle them to have their shares registered on
registration statements relating to primary or secondary registered public
offerings of the Company's securities. The parties to the Amended and Restated
Investor Rights Agreement are subject to certain cutback restrictions in
connection with any public offerings of the Company's equity securities.
 
    CREDIT FACILITY LENDER WARRANT.  Pursuant to a warrant (the "Lender
Warrant") to purchase 800,000 shares of Series B Common Stock issued to one of
the Lenders in connection with the Credit Facility, the holder thereof is
entitled, subject to certain exceptions and requirements more particularly set
forth therein, to demand two long-form registrations; PROVIDED, HOWEVER, that
the Company is not required to effect such demand registrations prior to the
earlier to occur of January 31, 2000 or the Company's first firm commitment
public offering of its Series B Common Stock. The holder of the Lender Warrant
also possesses "piggyback" registration rights which entitle it to have its
shares registered on registration statements relating to primary or secondary
registered public offerings of the Company's securities. The holder of the
Lender Warrant is subject to certain cutback restrictions in connection with any
public offerings of the Company's equity securities.
 
    PREVIOUS LENDER WARRANT.  Pursuant to two warrants to purchase an aggregate
amount of 470,092 shares of Series B Common Stock issued to a previous lender of
the Company, the holder thereof was granted the same rights to "piggyback"
registrations as were granted to the parties under the Amended and Restated
Investor Rights Agreement.
 
   
    PRIVATE NOTE WARRANTS.  Beginning the earlier of April 15, 2003 or 180 days
after an initial Public Equity Offering, the holders of one-quarter or more of
the Private Note Warrants and the Warrant Shares will be entitled to require the
Company to effect one demand registration (the "Demand Registration") under the
Securities Act of the Warrant Shares, subject to certain limitations. Upon a
demand, the Company will (a) notify the holders of all Warrants and Warrant
Shares that a demand registration has been requested, (b) prepare, file and use
its best efforts to cause to become effective within 120 days of such demand a
registration statement in respect of all of the Warrant Shares which holders
request, no later than 30 days after the date of such notice, to have included
therein (the "Included Securities"); PROVIDED, that the Company shall not be
required to so notify holders of Warrants and Warrant Shares and file such
demand registration statement within 90 days following any underwritten offering
of equity securities for the Company's own account or within 60 days following
any underwritten offering of equity securities for the account of any
securityholder of the Company, and (c) keep such registration statement
continuously effective for the shorter of (i) 180 days (the "Effectiveness
Period") or (ii) such period of time as all of the Warrant Shares included in
such registration statement shall have been sold thereunder; PROVIDED, that the
Company may postpone the filing period, suspend the effectiveness of any
registration statement, suspend the use of any prospectus and shall not be
required to amend or supplement the registration statement, any related
prospectus or any document incorporated therein by reference (a "Black Out
Period") in the event that (i) an event or circumstance occurs and is continuing
as a result of which the registration statement, any related prospectus or any
document incorporated therein by
    
 
                                      111
<PAGE>
   
reference as then amended or supplemented would, in the Company's good faith
judgment, contain an untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading or (ii) for a
period of up to 90 days, the Company reasonably and in good faith determines
that the filing or effectiveness of, or sales pursuant to, such registration
statement would materially interfere with any significant pending transaction
involving the Company or require disclosure of material information which the
Company has a bona fide business purpose for keeping confidential; PROVIDED
FURTHER, that the Effectiveness Period shall be extended by the number of days
in any Black Out Period. In the event of any Black Out Period, the Company will
so notify the holders of Warrants and Warrant Shares. Holders of Warrant Shares
have priority for inclusion in a Demand Registration over any other security
holders seeking to include securities in such registration.
    
 
   
    Holders of Warrants and Warrant Shares will also have the right to include
the Warrant Shares in any registration statement under the Securities Act filed
by the Company for its own account or for the account of any of its security
holders covering the sale of Common Stock (other than (a) a registration
statement on Form S-4 or S-8, (b) a registration statement filed in connection
with an offer of securities solely to existing security holders or any offer of
debt securities or convertible debt securities or (c) a Demand Registration) for
sale on the same terms and conditions as the securities of the Company or any
other selling security holder included therein (a "Piggy-Back Registration") if
and whenever any such registration statement is filed under the Securities Act,
except that the Piggy-Back Registration right of holders of Warrants and Warrant
Shares shall not apply to any Public Equity Offering that is the initial Public
Equity Offering of the Company unless the securities of other selling security
holders are to be included therein. In the case of a Piggy-Back Registration,
the number of Warrant Shares requested to be included therein is subject to pro
rata reduction (a "Cut Back") based upon the number of Warrant Shares and other
securities held by each holder of Warrants and Warrant Shares and any other
security holders exercising piggy-back registration rights to the extent that
the Company is advised by the managing underwriter, if any, therefor that the
total number or type of Warrant Shares or other securities to be included
therein is such as to materially and adversely affect the success of the
offering, except that (i) 800,000 shares of Series B Common Stock issuable upon
exercise of the Lender Warrant generally have seniority for inclusion over the
Warrant Shares and securities having registration rights under the Amended and
Restated Investor Rights Agreement and (ii) in the case of a demand registration
under the Amended and Restated Investor Rights Agreement holders of demand
registration rights thereunder have priority over the Warrant Shares and
securities issuable upon exercise of a the Lender Warrant.
    
 
   
    If the Company has complied with all its obligations with respect to a
Demand Registration or a Piggy-Back Registration relating to an underwritten
public offering, all holders of Warrants and Warrant Shares, upon request of the
lead managing underwriter with respect to such underwritten public offering,
will be required to not sell or otherwise dispose of any Warrants and Warrant
Shares owned by them for a period not to exceed 180 days from the consummation
of such underwritten public offering; PROVIDED, that except for the initial
Public Equity Offering of the Company, such requirement shall apply to Warrant
Shares not sold in a Demand Registration or Piggy-Back Registration due to a Cut
Back for a period not to exceed 90 days from such date of consummation.
    
 
            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
 
    The following are the material federal tax income consequences expected to
result to holders whose Private Notes are exchanged for Exchange Notes in the
Exchange Offer. This discussion is based upon current provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), applicable Treasury regulations,
judicial authority and administrative rulings and practice. There can be no
assurance that the Internal Revenue Service (the "Service") will not take a
contrary view, and no ruling from the Service has been or will be sought with
respect to the Exchange Offer. Legislative, judicial or administrative changes
or interpretations may be forthcoming that could alter or modify the statements
and conclusions set forth
 
                                      112
<PAGE>
herein. Any such changes or interpretations may or may not be retroactive and
could affect the tax consequences to holders. Certain holders (including
insurance companies, tax-exempt organizations, financial institutions,
broker-dealers, foreign corporations and persons who are not citizens or
residents of the United States) may be subject to special rules not discussed
below. EACH HOLDER OF PRIVATE NOTES SHOULD CONSULT ITS OWN TAX ADVISOR AS TO THE
PARTICULAR TAX CONSEQUENCES OF EXCHANGING PRIVATE NOTES FOR EXCHANGE NOTES,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN LAWS.
 
    The exchange of Private Notes for Exchange Notes should be treated as a
"non-event" for federal income tax purposes because the Exchange Notes should
not be considered to differ materially in kind or extent from the Private Notes.
As a result, no material federal income tax consequences should result to
holders exchanging Private Notes for Exchange Notes.
 
                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of Exchange Notes received in exchange for Private Notes
where such Private Notes were acquired as a result of market-making activities
or other trading activities. The Company has agreed that, starting on the
Expiration Date and ending on the close of business one year after the
Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until            , 199 , all dealers effecting transactions in the
Exchange Notes may be required to deliver a prospectus.
 
    The Company will not receive any proceeds from any sale of Exchange Notes by
broker-dealers. Exchange Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the Exchange Notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit of any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.
 
    For a period of one year after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
holders of the Notes) other than commissions or concessions of any brokers or
dealers and will indemnify the holders of the Notes (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

                                    EXPERTS
 
    The financial statements as of September 30, 1996 and 1997 and for each of
the three years in the period ended September 30, 1997 and for the period from
September 1, 1993 (inception) through September 30, 1997, included in this
Prospectus, have been so included in reliance on the report of Price Waterhouse
LLP, independent accountants, given on the authority of said firm as experts in
auditing and accounting.
 
                             CHANGE IN ACCOUNTANTS
 
    Effective November 1996, the Company engaged Price Waterhouse LLP as the
Company's independent accountants and dismissed Coopers & Lybrand L.L.P. as its
independent accountants. The decision to change independent accountants was
approved by the Company's Board of Directors. The reports of Coopers & Lybrand
L.L.P. on the Company's financial statements for the two years ended September
30, 1995, and for the period from September 1, 1993 (inception) through
September 30, 1995, did not contain an adverse opinion or disclaimer of opinion
and were not qualified or modified as to audit scope or accounting principles.
There were no disagreements with Coopers & Lybrand L.L.P. on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedures during the two years ended September 30, 1995, and for the
period from September 1, 1993 (inception) through September 30, 1995, and
through the date of their dismissal. Coopers & Lybrand L.L.P. has not audited or
reported on any financial statements subsequent to September 30, 1995. Prior to
November 1996, the Company had not consulted with Price Waterhouse LLP on items
which involved the Company's accounting principles or the form of audit opinion
to be issued on the Company's financial statements.

S-4 under the Securities Act with respect to the Exchange Notes offered hereby.

being qualified in all respects by such reference.
 
    Pursuant to the Indenture, the Company has agreed to furnish to the Trustee
and to registered holders of the Notes, without cost to the Trustee or such
registered holders, copies of all reports and other information that would be
required to be filed by the Company with the Commission under the Exchange Act,
whether or not the Company is then required to file reports with the Commission.
As a result of this Exchange Offer, the Company will become subject to the
periodic reporting and other informational requirements of the Exchange Act. In
the event that the Company ceases to be subject to the informational
requirements of the Exchange Act, the Company has agreed that, so long as any
Notes remain outstanding, it will file with the Commission (but only if the
Commission at such time is accepting such voluntary filings) and distribute to
holders of the Private Notes or the Exchange Notes, as applicable, copies of the
financial information that would have been contained in such annual reports and
quarterly reports, including a "Management's Discussion and Analysis of
Financial Condition and Results of Operations," that would have been required to

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
FirstWorld Communications, Inc. (formerly SpectraNet International)
 
    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of shareholders' equity (deficit) and of
cash flows present fairly, in all material respects, the financial position of
FirstWorld Communications, Inc. (formerly SpectraNet International) and its
subsidiaries, a development stage enterprise, at September 30, 1996 and 1997,
and the results of their operations and their cash flows for each of the three
years in the period ended September 30, 1997 and for the period from September
1, 1993 (inception) through September 30, 1997, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--THE COMPANY
 
   
    FirstWorld Communications, Inc. (the Company) commenced operations on
September 1, 1993 as a result of a Separation Agreement (the Separation
Agreement) by and among key shareholders of Lambda Link, a Nevada corporation
(Lambda Link), and Lambda Link. Pursuant to the Separation Agreement, two of the
three principal shareholders of Lambda Link (the Separating Shareholders)
exchanged the stock that they held in Lambda Link for 100 shares of Lambda Link
International, a California corporation (Lambda Link International),
representing all of the issued and outstanding stock of this wholly-owned
subsidiary of Lambda Link. In addition, the Separating Shareholders resigned
from the board of directors of Lambda Link, agreed to change the name of Lambda
Link International, and assumed certain of the existing assets and liabilities
of Lambda Link. In connection with the Separation Agreement, Lambda Link
International changed its name to SpectraNet International and assumed those
certain assets and liabilities of Lambda Link that the Separating Shareholders
received pursuant to the Separation Agreement. The transfer of such assets and
liabilities was accounted for at historical cost, which approximated the
purchase price. As discussed in Note 12, SpectraNet International changed its
name to FirstWorld Communications, Inc. on January 29, 1998.
    
 
    The Company is a facilities-based integrated communications provider which
is developing networks to provide telecommunications solutions to business
customers in clustered, demographically attractive second tier markets. The
Company offers a broad array of telecommunications services, including local and
long distance telephone service, high speed Internet access, data connectivity,
LAN connectivity, web hosting and system integration services. During July 1997,
the Company commenced operations associated with the first phase of its initial
telecommunications network cluster located in Anaheim, California.
 
NOTE 2--DEVELOPMENT STAGE ACTIVITIES AND DEPENDENCY ON ADDITIONAL FINANCING
 
    The Company is a development stage enterprise which has incurred substantial
operating losses and negative cash flows from network development and operations
since inception. The Company has provided services for less than three months as
of September 30, 1997 and has not achieved a significant customer base. To date,
the Company has focused primarily on the development of its product line, the
development and construction of its networks, the hiring of management and other
key personnel, the raising of capital, the acquisition of equipment, the
implementation of its sales and marketing strategy and the development of
operating systems. The development of the Company's business and the deployment
of its services and systems will require significant additional capital
expenditures, a substantial portion of which will need to be incurred before the
realization of significant revenues. Together with associated start-up operating
expenses, these capital expenditures will result in substantial negative cash
flow until an adequate revenue-generating customer base is established. In order
to implement its business plan, significant capital will be required to fund
capital expenditures, working capital, debt service and operating losses. The
Company's principal capital expenditure requirements involve the purchase,
installation and construction of network operations centers, other network
infrastructure and customer located equipment, including expenditures which
relate to the development and construction of the Anaheim network pursuant to
that certain Universal Telecommunications System Participation Agreement
described in Note 8, expenditures which will be required pursuant to those
certain agreements with The Irvine Company described in Note 12, as well as
expenditures associated with the expansion of its networks into additional
geographic clusters.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 2--DEVELOPMENT STAGE ACTIVITIES AND DEPENDENCY ON ADDITIONAL FINANCING
(CONTINUED)
    The Company expects that its future capital requirements will require it to
obtain additional financing, which may include commercial bank borrowings,
vendor financing, or the sale or issuance of equity and debt securities either
through one or more offerings or to one or more strategic investors. There can
be no assurance that the Company will be successful in raising additional
capital in sufficient amounts to fund its strategic objectives, or that such
funds, if available, will be available on terms that the Company will consider
acceptable. Failure to raise sufficient funds may require the Company to modify,
delay or abandon some of its planned future expansion or expenditures, which
could have a material adverse effect on the Company's business, financial
condition and results of operations, including the Company's ability to make
principal and interest payments on its then existing indebtedness.
 
    As discussed in Note 12, the Company consummated a private placement of
common stock on December 30, 1997, which resulted in the receipt of
approximately $26,330,000 in net proceeds on January 6, 1998. It is the opinion
of Company management that such net proceeds, along with the available borrowing
base on the Company's revolving credit facility (Note 6), will be adequate to
support the Company's operations through September 30, 1998. However, based upon
the factors discussed above, there can be no assurance that the Company will
achieve profitability or positive cash flow in the future or that sufficient
financing will be available to complete the Company's planned network
development efforts.
 
NOTE 3--SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
    The consolidated financial statements include the accounts of FirstWorld
Communications, Inc. and its wholly-owned subsidiaries. All intercompany
accounts and transactions have been eliminated in consolidation.
 
USE OF ESTIMATES
 
    The preparation of financial statements, in conformity with generally
accepted accounting principles, requires management to make certain estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Among the more significant estimates and
assumptions made by management are those related to the Company's projected
future earnings and cash flows. Estimates of future earnings and cash flows form
the basis for management's assessment of the Company's ability to continue as a
going concern and the basis for management's assessment of the realizability of
the Company's intangible and long-lived assets. The Company's earnings and cash
flows have been and will continue to be affected by a number of influences;
therefore, actual earnings and cash flows could differ from management's
estimates.
 
CASH EQUIVALENTS AND RESTRICTED CASH
 
    The Company considers all highly liquid investments with original maturities
of three months or less at the time of purchase to be cash equivalents. The
Company invests primarily in high-grade short-term investments which consist of
money market instruments. Restricted cash in support of outstanding letters of
credit totaled $50,000 at September 30, 1997.

NOTE 3--SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION
 
    The Company recognizes service revenue on local competitive access services
in the month such services are provided. Billings to customers for services in
advance of providing such services are deferred and recognized as revenue when
earned. Service revenues recognized since the Company's inception consist
primarily of reimbursable engineering, design and construction costs associated
with network service contracts with two city governments, which revenues have
been recognized as the services are provided by the Company. Other revenues
consist primarily of royalties earned under a certain patent licensing agreement
and are recorded when earned and when payment is reasonably assured.
 
CONCENTRATION OF CREDIT RISK
 
   
    The Company's financial instruments that are exposed to concentrations of
credit risk consist principally of cash and cash equivalents and accounts
receivable. The Company places its cash and temporary cash investments with
high-quality financial institutions for which credit loss is not anticipated.
Accounts receivable at September 30, 1997 are due from commercial
telecommunications customers, approximately 70 percent of which relates to a
single customer. Credit is extended based on an evaluation of the customer's
financial condition and generally collateral is not required. The Company
maintains reserves for potential credit losses. The Company has not provided for
any anticipated credit loss as of September 30, 1997 as all amounts are
considered by management to be fully collectible.
    
 
PROPERTY AND EQUIPMENT
 
    Property and equipment is recorded at cost and is depreciated using the
straight-line method over the estimated useful lives of the assets. Costs
capitalized in connection with the development of communication networks include
expenses associated with network engineering, design and construction.
Depreciation of communications networks and related infrastructure commences
when the applicable network becomes commercially operational.
 
    The estimated useful lives of the Company's principal classes of assets are
as follows:
 
<TABLE>
<S>                                 <C>
Network infrastructure............  20 years
Telecommunications equipment......  5-7 years
Building and improvements.........  30 years
Furniture, office equipment and
  other...........................  3-7 years
                                    Shorter of estimated useful life or
Leasehold improvements............  lease term
</TABLE>
 
CAPITALIZATION OF INTEREST
 
    Interest costs incurred during the period of time that internally
constructed assets are being made ready for their intended use are capitalized
as part of acquiring such assets to the extent that these interest costs relate
to financing obtained in order to prepare such assets for use. During fiscal
1997, the Company capitalized approximately $52,000 in interest costs associated
with the development of the Company's initial telecommunications network in
Anaheim, California.

NOTE 3--SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
DEFERRED FINANCING COSTS
 
    Deferred financing costs include commitment fees and other costs related to
certain debt financing transactions and are being amortized over the initial
term of the related debt using the interest method.
 
PATENTS
 
    Costs associated with the registration of patents are deferred and amortized
using the straight-line method over the estimated useful lives of the associated
patents, which approximates five years.
 
DEBT DISCOUNT
 
    Discounts recorded in connection with the issuance of debt financing are
deferred and amortized over the initial term of the related debt using the
interest method.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts shown for cash equivalents, short-term borrowings and
convertible bridge notes approximate their fair values due to the relatively
short-term maturities of these instruments. Management believes that the
carrying amounts shown for long-term debt are reasonable approximations of their
fair values based upon the interest rates at which the Company could enter into
similar borrowing arrangements.
 
LONG-LIVED ASSETS
 
    The Company assesses potential impairments to its long-lived assets when
there is evidence that events or changes in circumstances have made recovery of
the asset's carrying value unlikely. Potential impairment associated with
network infrastructure costs is measured on the basis of specific network
projects. An impairment loss would be recognized when the sum of the expected
future net cash flows is less than the carrying amount of the asset. No such
impairment losses have been identified by the Company during the fiscal years
presented.
 
STOCK-BASED COMPENSATION ACCOUNTING
 
    The Company measures compensation expense for its stock-based employee
compensation plans using the intrinsic value method and provides pro forma
disclosures of net loss as if the minimum value method had been applied in
measuring compensation expense. Compensation charges for non-employee
stock-based compensation is measured using fair value-based methods.
 
INCOME TAXES
 
    Current income tax expense is the amount of income taxes expected to be
payable for the current year. A deferred tax asset or liability is computed for
both the expected future impact of differences between the financial statement
and tax bases of assets and liabilities and for the expected future tax benefit
to be derived from tax loss and tax credit carryforwards. Valuation allowances
are established when necessary to reduce deferred tax assets to the amount
expected to be "more likely than not" realized in

NOTE 5--SHORT-TERM BORROWINGS
 
    On August 29, 1997, the Company obtained a $1,000,000, 18% per annum,
short-term bridge loan with an institutional lender which was due on October 15,
1997. On September 17, 1997, the Company repaid $500,000 of the outstanding
principal balance associated with this loan, plus accrued interest thereon, and
extended the maturity date of the remaining principal balance of $500,000 to
March 16, 1998

NOTE 5--SHORT-TERM BORROWINGS (CONTINUED)
through the consummation of a new loan agreement with the lender. The remaining
obligation under the new loan agreement, which bears interest at the rate of 18%
per annum, is collateralized by substantially all assets of the Company,
subordinate to the revolving credit facility described in Note 6. In connection
with the initial debt issuance on August 29, 1997, the Company issued to the
lender warrants for the purchase of 125,000 shares of common stock (Note 10).
The fair value of such warrants at the time of grant, as determined by
management based upon application of the Black-Scholes option pricing model, was
recorded as a discount on the underlying debt. Simultaneous to the execution of
the new loan agreement on September 17, 1997, which was considered to be a
substantial modification of the original loan agreement which it superseded, the
Company recognized an extraordinary charge on debt extinguishment totaling
$104,680. The extraordinary charge consisted of the write-off of unamortized
debt discount and deferred financing costs totaling $77,267 and $27,413,
respectively. Concurrently, the Company issued to the lender additional warrants
for the purchase of 175,000 shares of common stock (Note 10). The fair value of
these warrants at the time of grant, as determined by management based upon
application of the Black-Scholes option pricing model, has been recorded as a
discount on the underlying debt. The unamortized portion of the debt discount as
of September 30, 1997 totaled $148,738.
 
    On September 2, 1997, the Company issued a $50,000, 10% per annum, unsecured
promissory note to a financial adviser of the Company as payment for services
performed in connection with the attainment of debt financing. The note was
repaid on October 2, 1997.

REVOLVING CREDIT FACILITY
 
    On September 16, 1997, the Company entered into a revolving credit facility
(the Credit Facility) with a syndicate of lenders (the Lenders) to provide
financing for the construction of telecommunication networks and for general
working capital purposes. Under the terms of such facility, the Company has
available a maximum borrowing capacity of $23,000,000, which may be used for
either revolving loan advances or to support letters of credit. Subject to the
terms and conditions set forth in the Credit Facility, maximum borrowings at
anytime outstanding may not exceed the sum of the following: (i) 75% of approved
capital expenditures, as defined in the Credit Facility, plus (ii) eligible
accrued interest, as defined in the Credit Facility, plus (iii) $3,000,000. The
obligations of the Company under the Credit Facility have been collateralized,
in favor of the Lenders, by a first priority, perfected security interest in
substantially all of the Company's assets, including all present and future cash
balances, accounts receivable, inventories, property and equipment and general
intangibles.
 
    Advances under the Credit Facility bear interest at the rate of 14% per
annum and are payable monthly in arrears at a cash pay rate of 6% per annum in
year one, 9% in year two, 12% in year three and 14% thereafter, with the
remainder accruing at a compounded monthly basis and being added to the maximum
borrowing base. The Company is required to pay an annual maintenance fee of
$210,000 and a monthly commitment fee equal to .5% per annum on the average
unused portion of the maximum borrowings under the Credit Facility. The Company
is also required to pay a letter of credit fee equal to .5% per month on the
aggregate undrawn amount of all outstanding letters of credit.
 
    The Credit Facility imposes certain operating and financial restrictions on
the Company. Such restrictions affect, and in some cases limit or prohibit,
among other things, the ability of the Company to incur additional indebtedness,
repay certain indebtedness prior to its stated maturity, create liens, engage in
mergers and acquisitions, make certain capital expenditures or pay dividends. In
addition to such restrictions, the Company is required to maintain annualized
revenues which exceed certain minimum amounts as specified in the Credit
Facility. Failure to comply with these or any other of the covenants specified
in the Credit Facility constitutes an event of default, at which time all loan
obligations of the Company under this facility would immediately bear interest
at a rate of 18% per annum and the letter of credit fee would increase to .83%
per month. Upon the occurrence and during the continuation of an event of
default, all loan obligations under this facility would become immediately due
and payable at the sole discretion of the Lenders. At September 30, 1997, the
Company was in compliance with the covenants contained in the Credit Facility.

NOTE 6--LONG-TERM DEBT (CONTINUED)
    The Credit Facility matures on September 17, 2002. However, the Lenders, at
their sole discretion, may terminate this agreement on September 17, 2000. In
the event that the facility is terminated by the Company prior to the maturity
date, the Company must pay the Lenders a termination fee equal to the greater of
either $1,000,000 or the total interest and letter of credit fees for the
immediate six months preceding the termination date.
 
    In connection with the consummation of the Credit Facility, the Company
granted to the Lenders warrants for the purchase of 800,000 shares of the
Company's common stock (Note 10). The aggregate fair value of these warrants at
their time of grant, as determined by management based upon application of the
Black-Scholes option pricing model, has been recorded as a discount on the
underlying debt. The unamortized portion of the debt discount as of September
30, 1997 totaled $463,513.
 
NOTE 7--CONVERTIBLE BRIDGE NOTES
 
    During the period from August 9, 1996 through September 30, 1996, the
Company raised $835,000 through the issuance of 6.15% convertible bridge notes
maturing on January 31, 1997. During the period from October 1, 1996 to January
31, 1997, additional funding of $6,941,500 was received through the issuance of
such notes. On January 31, 1997, the aggregate principal balance of such notes
was converted by the holders into 1,555,300 shares of Series C convertible
preferred stock and related common stock warrants (Notes 9 and 10). Simultaneous
to this conversion, accrued interest on the associated notes totaling $116,812
was repaid by the Company to the note holders.
 
    On May 30, 1997, the Company authorized the private placement of up to
$5,000,000 in principal funding through the issuance of 8% subordinated,
convertible bridge notes. As of September 30, 1997, the Company had received
proceeds totaling $405,500 from this financing. Pursuant to the individual note
agreements, the convertible bridge notes were to mature on December 31, 1997,
unless earlier converted or repaid upon the closing of an equity financing by
the Company in excess of $3,000,000. As discussed in Note 12, the convertible
bridge notes outstanding as of September 30, 1997 were converted into shares of
the Company's Series A common stock and related warrants at the conversion rate
of $3.00 per share. In connection with the issuance of such convertible bridge
notes, warrants for the purchase of 33,789 shares of the Company's common stock
were also issued to the note holders (Note 10). It is management's estimate that
the aggregate value of these warrants, based upon application of the
Black-Scholes option pricing model, was insignificant at their time of grant.
 
NOTE 8--COMMITMENTS
 
LEASE COMMITMENTS
 
    The Company leases its office space, certain network access facilities and
automobiles under noncancelable operating lease arrangements which expire on
varying dates through fiscal 2002. Certain of the office leases contain rent
escalation clauses which require the Company to pay a pro-rata share of the
lessor's operating expenses for any calendar year which exceeds base year
operating expenses, as defined within the respective agreements.
 
    The Company has procured certain of its property and equipment, including
its Anaheim network central office switching facility, through capital leases
which expire through fiscal 2001. Additionally, the

OTHER COMMITMENTS
 
    During February 1997, the Company and its wholly-owned subsidiary FirstWorld
Anaheim (FWA) entered into a 30-year Universal Telecommunications System
Participation Agreement (the UTS Agreement) with the City of Anaheim, California
(the City), under which FWA has agreed to design, construct and operate a
fiber-optic telecommunications network in cooperation with the City. The UTS
Agreement requires FWA to pay to the City (i) an annual payment in lieu of a
franchise fee based on a percentage of FWA's "adjusted gross revenues," as
defined, related to the Anaheim network, subject to a minimum annual payment of
$1,000,000 for periods after June 30, 1999 through the term of the agreement,
(ii) a percentage of FWA's "net revenues," as defined, derived from the Anaheim
network, (iii) certain of the City's annual operating costs associated with the
UTS Agreement, not to exceed $175,000 per year prior to the commencement of the
third phase of the Anaheim network (as discussed below), and not to exceed
$350,000 per year thereafter, subject to inflationary adjustments, and (iv)
$20,000 per year to support the City's presence on the Internet, subject to
inflationary adjustments. The UTS Agreement also requires the Company to deposit
an amount equal to up to 15% of net revenues derived from the Anaheim network to
maintain a $6,000,000 reserve account for debt service and capital improvements.
Pursuant to the UTS Agreement, the City has been granted an irrevocable option
to purchase all of the issued and outstanding stock of FWA at anytime after July
1, 2012 for its then current appraised fair value, the determination of which is
to be derived by qualified independent appraisers selected by both the Company
and the City, as more specifically defined within the UTS Agreement. Any sale or
issuance of FWA stock can only be made if such sale or issuance is expressly
made subject to the City's purchase option. Moreover, any sale of the Anaheim
network or other sale of substantially all of FWA's assets can only be made if
the City is equitably

compensated for the loss of its future income stream under the UTS Agreement or
the buyer expressly assumes the obligations of FWA under the UTS Agreement.
 
    Simultaneous to the execution of the UTS Agreement, FWA entered into a
30-year Agreement for Use of Operating Property (the Operating Property
Agreement) with the City under which FWA has been granted the exclusive right to
lease 60 of 96 fiber strands contained in an approximate 50 mile loop of fiber
optic cable owned by the City, together with related facilities and rights.
Under the terms of the Operating Property Agreement, the Company is obligated to
make quarterly payments to the City in the minimum amount of $113,862. In
addition, the Company is obligated to pay all costs associated with operating
and maintaining the leased property, including maintenance expenses, taxes,
insurance premiums and pole usage fees. FWA has the right to assign its rights
under the Operating Property Agreement, but will not be released from liability
unless the City expressly consents. FWA also has the right to encumber its
interest in the leased property. FWA's interest in the leased property presently
is encumbered by a leasehold mortgage in favor of the lenders under the
Company's Credit Facility.
 
    Under the terms of the UTS Agreement and the Operating Property Agreement,
which have collectively been accounted for as a capital lease in the
accompanying financial statements, remaining fixed rental payments aggregate
approximately $46,959,000 at September 30, 1997. Interest expense associated
with this capital lease totaled $995,434 during fiscal 1997.
 
    Pursuant to the UTS Agreement, FWA is required to meet certain future
performance requirements for the completion of network design and the
commencement of network construction related to certain phases of the city-wide
network. The first phase, which extended service to identified municipal
facilities, was substantially completed in October 1997. The second phase, which
allows service to be extended in the ordinary course of business (i.e., within
six months following execution of a customer service agreement) to commercial,
industrial and governmental customers within certain defined service areas, is
required to be 44% completed by April 1, 1998, and 90% completed by December 31,
1998. The UTS Agreement also requires FWA to commence construction of a
demonstration center in the City's downtown area by August 20, 1998 and to
ensure that such demonstration center is operational by June 30, 1999. The
Company anticipates that the aforementioned performance requirements will be
met. In the event that FWA does not meet the specified performance deadlines
related to completion of the first and second phases of the Anaheim network due
to financial or other reasons, the City may elect to either terminate the
Operating Property Agreement or to immediately exercise its option to purchase
all of the issued and outstanding stock of FWA under the same option terms, as
defined within the UTS Agreement, which otherwise do not become effective until
after July 1, 2012. Any termination of the Operating Property Agreement would
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
    Under the UTS Agreement, the third phase of the Anaheim network, which
allows service to be extended in the ordinary course of business to all
customers within the city, including residential customers, will be commenced
only after the feasibility of the third phase is validated by an independent
consultant's report and financing is arranged. FWA has agreed to cause a
feasibility study with respect to the third phase to be completed no later than
January 1, 2000, and thereafter to provide annual updates to the study if
necessary. If the Company determines not to proceed with the development of the
third phase of the Anaheim network, or if for any reason the principal financing
for the third phase is not funded or

construction of the third phase is not commenced by December 31, 2002, then the
City may pursue development of the third phase on its own.
 
    Pursuant to a Development Fee Arrangement dated simultaneous to the
aforementioned City agreements, for a period of five years, commencing with the
earlier to occur of the closing of the financing for or the commencement of
construction of the first Additional Network (as defined below), the Company
must pay to the City a lump sum development fee for each Additional Network
which the Company develops ($300,000 for each Additional Network financed in the
first year; $200,000 for each Additional Network financed in the second year;
and $100,000 for each Additional Network financed in the third, fourth and fifth
years, which amounts must be paid within thirty days following the closing of
the principal financing for an Additional Network or the commencement of
construction of such Additional Network, whichever occurs first). "Additional
Network" means (a) any expansion of the Anaheim network into one or more
adjacent or nearby cities where FWA enters into a revenue sharing agreement with
any such city, and (b) any separate communications system developed by any other
subsidiary of the Company that holds a Certificate of Public Convenience and
Necessity issued by the Public Utilities Commission and enters into a revenue
sharing agreement with one or more public entities.
 
    The Company is party to a contract with a long distance carrier pursuant to
which the Company is committed to minimum service fees. Such minimum fees
aggregate $312,500, $1,937,500 and $250,000 during each of fiscal 1998, 1999 and
2000, respectively.
 
NOTE 9--SHAREHOLDERS' EQUITY (DEFICIT)
 
    In December 1996, the Board of Directors and shareholders of the Company
approved a restatement of the Articles of Incorporation which provided for a
capital restructuring. Under the restated Articles of Incorporation, the Company
is authorized to issue up to 15,000,000 shares of common stock and 5,160,335
shares of preferred stock, of which 134,200 shares are designated Series A
preferred stock, 2,426,135 shares are designated Series B preferred stock and
2,600,000 shares are designated Series C preferred stock, and to fix the powers,
designations, preferences and rights of each series. As discussed in Note 12,
the Company converted the three existing classes of preferred stock and common
stock into shares of newly created Series B common stock on December 30, 1997.
 
COMMON STOCK
 
    In connection with the Separation Agreement (Note 1), the Separating
Shareholders received 100 shares of common stock. Consideration for such shares
consisted of the assumption of net liabilities from Lambda Link totaling
$404,621.
 
    In October 1993, the Company issued 2,519,900 shares of common stock as
compensation to the Separating Shareholders and certain employees in the amount
of $2,520.
 
    In March 1994, in connection with a private placement offering, the Company
issued 279,000 shares of common stock at a price of $1.50 per share. In June
1995, these shares were converted into Series B preferred stock.

    During the period May 1996 to June 1996, 330,000 shares of common stock were
issued through the exercise of stock options at prices between $.15 and $.25 per
share. Additionally, 396,000 shares of common stock were issued to certain
option holders pursuant to a Board of Directors' resolution which prescribed for
the cancellation of options in favor of purchasing a like number of shares of
common stock at $.25 per share.
 
    During the period November 1996 to August 1997, 106,900 shares of common
stock were issued through the exercise of stock options and warrants at prices
between $.15 and $.50 per share.
 
SERIES A PREFERRED STOCK
 
    The holders of Series A preferred stock are entitled to cumulative dividends
at the rate of $.20 per share per annum, when, as and if declared by the
Company's Board of Directors. The holders of Series A preferred stock are not
entitled to liquidating distributions. So long as any shares of Series A
preferred stock remain outstanding, no dividends or distributions shall be paid
on any Series B preferred stock or common stock of the Company during any fiscal
year, nor shall any shares of the Series B preferred stock or common stock be
purchased, redeemed, or otherwise acquired for value by the Company until Series
A preferred stock dividends in the total amount of $.20 per share shall have
first been paid or declared and set apart during that fiscal year and any prior
fiscal year in which dividends accumulated but remain unpaid. No dividends have
been declared on Series A preferred stock through September 30, 1997. Cumulative
dividends in arrears on Series A preferred stock aggregate $47,467, or $.40 per
share, as of September 30, 1997. Each share of Series A preferred stock is
convertible, at the option of the holder thereof, at anytime into a one-tenth
share of common stock. The Series A preferred shares shall automatically convert
into one-tenth of a share of common stock upon the closing of a firm commitment
underwritten public offering of the Company's common stock resulting in an
aggregate offering price of not less than $20,000,000 based upon an offering
price per common share of not less than (i) $10.00 for an offering which occurs
prior to December 31, 1998; (ii) $12.50 for an offering which occurs after
December 31, 1998 and on or prior to December 31, 1999; (iii) $15.00 for an
offering which occurs after December 31, 1999 and on or prior to December 31,
2000; or (iv) $17.50 for an offering which occurs after December 31, 2000. Each
share of Series A preferred stock shall also be converted into one-tenth of a
share of common stock upon the affirmative vote of the holders of a majority of
the shares of such series outstanding at the time of vote. The number of common
shares in which Series A preferred stock may be converted pursuant to automatic
or voluntary events of conversion is subject to adjustment for customary events
of dilution. The Series A preferred shares do not have any voting rights.
 
    In May 1995, the Company issued 127,601 shares of Series A preferred stock
to employees in exchange for the cancellation of notes and wages payable, which
conversion was made at the rate of $3.33 per share based upon the carrying
amounts of said liabilities.
 
    In January 1996, the Company repurchased 8,934 shares of Series A preferred
stock at their original cost of $3.33 per share through the issuance of a note
payable.

preferred dividends payable when and as declared by the Company's Board of
Directors. No dividends shall be paid on any share of Series B preferred stock
until dividends associated with Series C and Series A preferred stock have been

preferred stock through September 30, 1997. In the event of liquidation,
dissolution or winding up of the Company, Series B holders are entitled to

share per annum beginning July 1, 1995. Each share of Series B preferred stock
is convertible, at the option of the holder thereof, at anytime into equal
shares of common stock. The Series B preferred shares shall automatically
convert into equal shares of common stock upon the closing of a firm commitment
underwritten public offering of the Company's common stock resulting in an
aggregate offering price of not less than $20,000,000 based upon an offering
price per common share of not less than (i) $10.00 for an offering which occurs
prior to December 31, 1998; (ii) $12.50 for an offering which occurs after
December 31, 1998 and on or prior to December 31, 1999; (iii) $15.00 for an
offering which occurs after December 31, 1999 and on or prior to December 31,
2000; or (iv) $17.50 for an offering which occurs after December 31, 2000. Each
share of Series B preferred stock shall also be converted into equal shares of
common stock upon the affirmative vote of the holders of a majority of the
shares of such series outstanding at the time of vote. The number of common
shares in which Series B preferred stock may be converted pursuant to automatic
or voluntary events of conversion is subject to adjustment for customary events
of dilution. The Series B preferred shares, on an as-converted basis, have equal
voting rights as the Company's common shares.
 
    In June 1995, 279,000 shares of common stock were exchanged for Series B
preferred stock.
 
    During the period January 1995 to September 1995, in connection with a
private placement offering, the Company issued 558,669 shares of Series B
preferred stock at a price of $1.50 per share. Additionally, during the period
October 1995 to January 1996, the Company issued 500,504 shares of Series B
preferred stock at a price of $1.50 per share.
 
    In December 1995, the Company issued 33,334 shares of Series B preferred
stock for the cancellation of a note payable to a relative of the president and
for consulting services received, which conversion was based upon the fair value
of Series B preferred stock of $1.50 per share, the carrying amount of the note
payable and the fair value of the consulting services received.
 
    During the period January 1996 to June 1996, in connection with a private
placement offering, the Company issued 641,800 shares of Series B preferred
stock at a price of $2.50 per share.
 
    In May 1996, the Company issued 3,333 shares of Series B preferred stock for
the procurement of property and equipment, which conversion was based upon the
fair value of Series B preferred stock of $2.50 per share and the fair value of
the property and equipment received.

dividends. Series C preferred stock dividends shall be payable only when, as and
if declared by the Company's Board of Directors and shall be noncumulative;
provided, however, that after December 31, 1998, the holders of Series C
preferred stock shall be entitled to receive cumulative dividends at the rate of
$.40 per share per annum. Such dividends shall be payable only when, as and if
declared by the Board of Directors and shall accrue after December 31, 1998,
whether or not earned. So long as any shares of Series C preferred stock remain
outstanding, no dividends or distributions shall be paid on the Series B or
Series A preferred stock or the common stock of the Company during any fiscal
year, nor shall any shares of the Series B or Series A preferred stock or the
common stock be purchased, redeemed, or otherwise acquired for value by the
Company until Series C preferred stock dividends in the total amount of $.40 per
share shall have first been paid or declared and set apart during that fiscal
year and any prior fiscal year in which dividends accumulated but remain unpaid.
No dividends have been declared on Series C preferred stock through September
30, 1997. Each share of Series C preferred stock is convertible, at the option
of the holder thereof, at anytime into equal shares of common stock. The Series
C preferred shares shall automatically convert into equal shares of common stock
upon the closing of a firm commitment underwritten public offering of the
Company's common stock resulting in an aggregate offering price of not less than
$20,000,000 based upon an offering price per common share of not less than (i)
$10.00 for an offering which occurs prior to December 31, 1998; (ii) $12.50 for
an offering which occurs after December 31, 1998 and on or prior to December 31,

converted into equal shares of common stock upon the affirmative vote of the
holders of a majority of the shares of such series outstanding at the time of
vote. The number of common shares in which Series C preferred stock may be
converted pursuant to automatic or voluntary events of conversion is subject to
adjustment for customary events of dilution, as well as certain additional
anti-dilutive adjustments as defined in the Company's Articles of Incorporation.
The Series C preferred shares, on an as-converted basis, have equal voting
rights as the Company's common shares.
 
    Pursuant to the Articles of Incorporation, the Company shall not, without
first obtaining the affirmative vote or written consent of the holders of not
less than two-thirds of the outstanding shares of Series C preferred stock, (i)
pay or declare dividends on common stock or repurchase any shares of capital
stock of the corporation; (ii) take any action to materially amend the Company's
Articles of Incorporation or Bylaws; (iii) authorize or issue shares of capital
stock having preference equal to or superior to that of the Series C preferred
shares; or (iv) effect certain mergers or consolidations of the Company, each as
defined within the Articles of Incorporation.
 
    During January 1997, in connection with a private placement offering, the
Company issued 2,600,000 shares of Series C preferred stock, consisting of
1,044,700 shares issued for cash proceeds totaling $4,528,862, net of placement
agent commissions and related fees, and 1,555,300 shares issued through the
retirement of convertible bridge notes (Note 7). In connection with this
offering, the holders of Series C shares also received warrants for the purchase
of 520,000 shares of common stock; additionally, warrants to purchase 233,118
shares of common stock were issued to certain financial advisors (Note 10).

NOTE 10--WARRANTS AND STOCK OPTIONS
 
WARRANTS
 
    In connection with the January 1994 private placement of common stock, the
Company issued warrants to purchase 139,494 shares of common stock at $1.50 per
share. During June 1995, these warrants were canceled and exchanged for warrants
to purchase 139,494 shares of Series B preferred stock at a price of $1.50 per
share, which warrants expire in April 1999 and contain customary adjustments to
protect against dilution. It is management's estimate that the aggregate fair
value of these warrants was insignificant at the time of grant. At September 30,
1997, all of these warrants remain outstanding.
 
    In connection with the January 1997 private placement of Series C preferred
stock, the Company issued warrants for the purchase of 520,000 shares of common
stock to the investors. Such warrants have an exercise price of $5.00 per share,
a term of five years and are subject to customary adjustments to protect against
dilution, as well as certain additional anti-dilutive adjustments as defined in
the warrant agreements. Based upon application of the Black-Scholes option
pricing model, it is management's estimate that the aggregate fair value of such
warrants was approximately $16,000 at the time of grant, which amount has been
allocated to the warrants. At September 30, 1997, all of these warrants remain
outstanding.
 
    In connection with the January 1997 private placement of Series C preferred
stock, the Company also issued to certain financial advisors warrants to
purchase 218,118 and 15,000 shares of common stock at exercise prices of $5.00
and $.50, respectively, all of which have terms of five years and contain
customary adjustments to protect against dilution. Based upon application of the
Black-Scholes option pricing model, it is management's estimate that the
aggregate fair value of such warrants was approximately $10,000 at the time of
grant, which amount has been recorded as a non-cash equity issuance cost related
to the Series C preferred stock placement. During March 1997, 5,000 of the $.50
warrants were exercised for proceeds totaling $2,500. At September 30, 1997, all
of the remaining warrants remain outstanding.
 
    Simultaneous to the above Series C equity transactions, the Company issued a
warrant for the purchase of 800,000 shares of common stock to a single investor.
The warrant has a term of five years and vests at the rate of 25% per year
beginning in January 1998. Pursuant to the warrant agreement, the initial
exercise price per underlying common share is $4.75. However, the warrant
contains a complex anti-dilution provision pursuant to which the number of
underlying common shares may be increased based upon the weighted average
issuance price of equity securities issued by the Company prior to the earliest
of (i) April 1, 1999, (ii) the death of the investor, and (iii) a public
offering of securities by the Company. The warrant also prescribes a formula
under which the exercise price per underlying common share is reduced in
successive years of the warrant agreement, which reduction is further affected
by the number of warrant shares previously exercised pursuant to this agreement.
This warrant was issued for cash proceeds totaling $200,000, which management
considers to be the fair value of this warrant at the time of grant. At
September 30, 1997, no shares have been exercised under this warrant agreement.
As discussed in Note 12, the terms of this warrant were amended on December 30,
1997.
 
    During January 1997, the Company issued to certain legal service providers
warrants to purchase 19,000 and 5,000 shares of common stock at exercise prices
of $.50 and $5.00, respectively. Such warrants have terms of five years and
contain customary adjustments to protect against dilution. It is management's
estimate that the aggregate fair value of these warrants, determined based upon
application of the Black-

Scholes option pricing model, was insignificant at their time of grant. At
September 30, 1997, all of these warrants remain outstanding.
 
    During the period July 1997 to September 1997, in connection with the
issuance of convertible bridge notes, warrants for the purchase of 33,789 shares
of common stock were issued to the note holders. Such warrants, which expire in
July 2002, have an exercise price of $6.00 per share and contain customary
adjustments to protect against dilution. It is management's estimate that the
aggregate fair value of these warrants, determined based upon application of the
Black-Scholes option pricing model, was insignificant at their time of grant. At
September 30, 1997, all of these warrants remain outstanding.
 
    During August 1997, in connection with the attainment of short-term bridge
financing, the Company issued to the lender warrants to purchase 125,000 shares
of common stock. During September 1997, in connection with the execution of a
new loan agreement, warrants to purchase an additional 175,000 common shares
were issued to the lender. Such warrants have an exercise price of $6.00 per
share, a term of seven years and are subject to customary adjustments to protect
against dilution, as well as certain additional anti-dilutive adjustments as
defined in the warrant agreements. The aggregate fair value of the warrants at
their date of grant, which was estimated by management to be $115,900 with
respect to the warrants issued during August 1997 and $162,260 with respect to
the warrants issued during September 1997, based upon application of the
Black-Scholes option pricing model, has been recorded as a discount on the
underlying debt. As discussed in Note 5, the unamortized debt discount
associated with those warrants issued in August 1997 was written off on
September 17, 1997 as a result of a debt extinguishment. At September 30, 1997,
all of these warrants remain outstanding.
 
    During September 1997, in connection with the attainment of the Company's
Credit Facility, the Company issued to the lender warrants to purchase 800,000
shares of common stock. Such warrants have an exercise price of $6.00 per share,
a term of five years and are subject to customary adjustments to protect against
dilution, as well as certain additional anti-dilutive adjustments as defined in
the warrant agreement. The fair value of these warrants at the time of grant,
which was estimated by management to be $469,600 based upon application of the
Black-Scholes option pricing model, has been recorded as a discount on the
underlying debt. In connection with the consummation of this credit facility,
the Company also issued to certain financial advisors warrants to purchase
83,400 shares of common stock, which warrants have an exercise price of $6.00
and a term of five years. The aggregate fair value of these warrants at the time
of grant, which was estimated by management to be $27,200 based upon application
of the Black-Scholes option pricing model, has been recorded as a non-cash
deferred financing cost. At September 30, 1997, all of the warrants issued in
connection with this transaction remain outstanding.
 
STOCK OPTIONS
 
    The Company has a 1995 Incentive Stock Option Plan (the 1995 Plan) and a
1997 Stock Plan (the 1997 Plan) (collectively, the Plans) under which stock
options or stock purchase rights to acquire an aggregate of 1,500,000 shares and
1,000,000 shares, respectively, of common stock may be granted to employees and
directors of the Company, as well as to non-employee consultants of the Company
under the 1997 Plan. As of September 30, 1997, 2,068,100 common shares remain
reserved for issuance under the Plans. Both plans provide for the granting of
incentive stock options (within the meaning of Section 422A

of the Internal Revenue Code) while the 1997 Plan also provides for the granting
of non-statutory stock options. Additionally, stock purchase rights may also be
granted under the 1997 Plan.
 
    The terms of stock options granted under the Plans are determined by the
Board of Directors. Stock options may be granted for periods of up to ten years
at a price per share not less than the fair market value of the Company's common
stock at the date of grant for incentive stock options and not less than 85% of
the fair market value of the Company's common stock at the date of grant for
non-statutory stock options. In the case of incentive and non-statutory stock
options granted under Plans to employees, directors or consultants who, at the
time of grant of such options, own stock representing more than 10% of the
voting power of all classes of stock of the Company, the exercise price shall be
no less than 110% of the fair market value of the Company's common stock at the
date of grant. Additionally, the term of incentive stock option grants under the
Plans is limited to five years if the grantee owns in excess of 10% of the
voting power of all classes of stock of the Company at the time of grant.
Options granted under the Plans generally vest to the option holder ratably over
a period of four to five years beginning on the grant date.
 
    The terms of stock purchase rights granted under the 1997 Plan are
determined by the Board of Directors. Stock purchase rights may be issued either
alone, in addition to, or in tandem with other awards granted under the 1997
Plan and/or cash awards made outside of the 1997 Plan. Through September 30,
1997, no such purchase rights have been granted by the Company.
 
    The Company measures compensation expense for its stock-based employee
compensation plans using the intrinsic value method and provides pro forma
disclosures of net loss as if the minimum value method had been applied in
measuring compensation expense. Had compensation cost for the Company's
stock-based compensation plans been determined based on the minimum value method
at the grant dates for awards under this plan consistent with the method
prescribed by Statement of Financial Accounting Standards No. 123, the Company's
net loss would have been increased to the pro forma amounts indicated below:

    The minimum value of each option grant is estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted average
assumptions used for grants during fiscal 1996 and 1997: dividend yield of 0.0%
for both periods; volatility of 0.0% for both periods; risk-free interest rates
of 5.79% and 6.07%; and an expected life of 5.0 years for both periods. The
weighted average fair value of options granted during fiscal 1996 and 1997 was
approximately $.06 and $.09 per option, respectively.

    As of September 30, 1997, the Company has Federal and state net operating
loss carryforwards of approximately $14,810,000 and $10,798,000, respectively,
which amounts expire beginning in fiscal 2009 and fiscal 1999, respectively. As
a result of the capital transactions described in Note 12, which resulted in a
change of ownership as defined by Section 382 of the Internal Revenue Code, the
Company's utilization of such net operating loss carryforwards will be subject
to an annual limitation of approximately $878,000 for both Federal and state tax
purposes, the effect of which has been reflected in the summary of deferred tax
assets above. Additionally, if the Company is able to recognize built-in gains
in the future, the annual utilization rate of the net operating losses would be
increased. If the Company is able to recognize built-in losses, they will be
subject to the annual utilization limitation when recognized.
 
    Based upon the lack of prior earnings history of the Company and based upon
available evidence, management has recorded a full valuation allowance for the
benefit of deferred tax assets. No income tax provision or benefit was recorded
during fiscal 1995, 1996 or 1997, or for the period from September 1, 1993
(inception) to September 30, 1997, due to the cumulative net losses of the
Company.
 
NOTE 12--SUBSEQUENT EVENTS
 
    In October 1997, the Company entered into a three-year network services
agreement with a provider of voicemail and data services. Future minimum
payments under this agreement, which extend through October 2000, aggregate
$56,670, $239,040, $286,560 and $23,880 during each of fiscal 1998, 1999, 2000
and 2001, respectively. Simultaneous to the consummation of this agreement, the
Company granted a three-year, $150,000 unsecured promissory note to the vendor
as payment for certain up-front fees associated with this agreement. Aggregate
principal and interest payments due under this promissory note total $10,800,
$48,600, $109,365 and $31,455 during fiscal 1998, 1999, 2000 and 2001,
respectively. Also in October 1997, the Company entered into a four-year
agreement with a provider of data processing and billing services, under which
future minimum payments aggregate $150,000 during each of fiscal 1998, 1999,
2000 and 2001.
 
    In December 1997, the Company's Board of Directors approved a repricing of
stock options whereby the exercise price of all outstanding stock options
granted under the Company's Plans was reduced to $3.00 per share, if previously
in excess of such amount.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 12--SUBSEQUENT EVENTS (CONTINUED)
    On December 30, 1997, the Company consummated a private placement of equity
securities with Colorado Spectra 3, LLC (Spectra 3) and Enron Capital & Trade
Resources Corp. (Enron). The Company issued 5,000,000 shares of newly created
Series A common stock to each of Spectra 3 and Enron at an issue price of $3.00
per share pursuant to a common stock purchase agreement by and among the
Company, Enron, Spectra 3 and the holders (the Noteholders) of $405,500 in
principal amount of the Company's convertible subordinated bridge notes (Note
7). The Company also issued an aggregate of 135,164 shares of Series A common
stock to the Noteholders upon the automatic conversion of the bridge notes
pursuant to the terms thereof at a conversion price of $3.00 per share.
Aggregate proceeds from this offering, exclusive of the conversion of the bridge
notes, totaled approximately $26,330,000, net of offering commissions and
certain other advisory fees paid in connection with the consummation of this
equity placement. The Company received the gross proceeds from this offering on
January 6, 1998, simultaneous to which the related offering costs were paid. In
connection with the aforementioned placement, the Company also issued to Spectra
3 and Enron warrants to purchase 5,000,000 shares each of newly created Series B
common stock and to the Noteholders warrants to purchase an aggregate of 135,164
shares of such Series B common stock at $3.00 per share. The number of shares of
Series B common stock and exercise price of the warrants are subject to
customary adjustments from time to time as stipulated in the warrant agreements.
Such warrants may be exercised at any time prior to the first to occur of (i)
December 30, 2004; (ii) the merger of the Company with or into another entity in
which the shareholders of the Company immediately prior to the merger own less
than 50% of the voting securities of the surviving entity immediately following
the merger; and (iii) the sale by the Company of all or substantially all of its
assets. It is management's estimate that the aggregate fair value of such
warrants approximates $9,628,000, based upon application of the Black-Scholes
option pricing model. The common stock purchase agreement, as amended, also
contains an option which grants Spectra 3 and Enron the right to invest an
additional $20,000,000 in the aggregate on the same terms and conditions
applicable to their purchases of Series A common stock as described above,
except that any additional shares of common stock to be acquired would be Series
B common stock. Such option is exercisable through the earlier of (i) June 9,
1998; or (ii) the closing of a high yield debt offering by the Company.
 
    Simultaneous to the equity investment described above, the Company (i)
converted the three existing classes of preferred stock into common stock in
accordance with the automatic conversion provision of its existing charter, in
order to simplify the Company's capital structure and to eliminate the rights,
preferences and privileges of the preferred stock; (ii) amended its Articles of
Incorporation to substantially increase the Company's authorized capital to
allow for the aforementioned equity transaction and to provide flexibility for
future anticipated financings; and (iii) amended its Articles of Incorporation
to designate two series of common stock, with the investors in the
aforementioned equity transaction receiving Series A common stock and all then
existing shares of common stock (including common stock issued upon conversion
of the existing preferred stock) being designated as Series B common stock. The
Series A common stock and Series B common stock are identical in all material
respects, except that the Series A common stock possess ten votes per share on
all matters subject to a vote of shareholders while the Series B common stock
possess one vote per share.
 
    In connection with the above transactions, the Company entered into separate
management consulting services agreements with an affiliate of Spectra 3 and
Enron whereby such parties will provide general management consulting services
to the Company for a period of three years beginning January 1, 1998.

NOTE 12--SUBSEQUENT EVENTS (CONTINUED)
Pursuant to such agreements, the Company will be required to pay to each party
consulting fees totaling $500,000 per annum.
 
    Simultaneous to the above private placement and related transactions, that
certain warrant for the purchase of 800,000 shares of common stock, as
originally granted by the Company to a single investor (an affiliate of Spectra
3) on January 31, 1997 (Note 10), was amended whereby the number of shares
purchasable under the warrant was set at 2,110,140 shares of Series B common
stock with an exercise price of $1.80 per share, as opposed to the 2,250,000
shares of Series B common stock with an exercise at $1.69 per share as would
have been purchasable following the aforementioned equity transactions pursuant
to the terms of the original warrant agreement. The warrant was amended in order
to fix the number of shares purchasable under the original warrant agreement and
to eliminate any further adjustment to the number of underlying Series B common
shares purchasable as a result of future equity issuances. This warrant, as
amended, remains subject to certain customary adjustments to protect against
dilution.
 
    On January 29, 1998, SpectraNet International changed its name to FirstWorld
Communications, Inc.
 
    On March 5, 1998, FirstWorld Orange Coast (FWOC), a wholly-owned subsidiary
of the Company, and The Irvine Company entered into two agreements regarding
FWOC's development of a network to serve certain areas that have been or are
planned to be developed by The Irvine Company (the Irvine Network). The Company
has guaranteed the payment obligations of FWOC under each of such agreements.
 
    Pursuant to an Agreement for Lease of Telecommunications Conduit dated as of
March 5, 1998 (the Conduit Lease), FWOC leases from The Irvine Company space
within two underground telecommunications tubes (the Conduit), and, in
connection therewith, has received the non-exclusive right to use undivided
space within the pull boxes serving such Conduit (collectively, the Leased
Premises). The Conduit Lease applies to (i) an existing Conduit system within
certain already-developed areas in the Irvine Spectrum and (ii) Conduit to be
constructed in the future in the as yet undeveloped areas of the Irvine
Spectrum. The Irvine Company may also install Conduit in other areas it may
develop in the cities of Irvine, Newport Beach and Tustin, and in unincorporated
areas of Orange County, and such areas may in the future be incorporated into
the Conduit Lease upon the mutual agreement of the parties (Additional Areas).
The term of the Conduit Lease runs through December 31, 2027.
 
    The Conduit Lease obligates FWOC to install fiber optic cable (Cable) in the
Conduit pursuant to a phasing plan. A phase is completed when sufficient Cable
has been installed to enable FWOC to connect and provide service (for that
portion of the Irvine Network) to property abutting the Conduit. Upon
termination of the agreement, the Cable will be owned by The Irvine Company. If
FWOC fails to complete installation of the required Conduit within 18 months
following March 5, 1998, The Irvine Company may, until such installation is
completed, terminate the Conduit Lease.
 
    FWOC is obligated to make quarterly rent payments to The Irvine Company
based upon its "adjusted gross revenue", as defined, from the Irvine Network. In
addition, FWOC is obligated to pay all costs associated with its lease,
operation, maintenance, repair and use of the Leased Premises, including
maintenance expenses, taxes and insurance premiums. Any assignment of FWOC's
rights under the Conduit Lease and any sale of a controlling interest in FWOC
require The Irvine Company's prior approval, and The Irvine Company has a right
of first refusal in the event of any such proposed sale.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 12--SUBSEQUENT EVENTS (CONTINUED)
    Concurrently with the execution of the Conduit Lease, FWOC and The Irvine
Company executed a Telecommunications System License Agreement (the License
Agreement) which provides FWOC, with some exceptions, with the right and
obligation to provide telecommunications services to (i) the 106 buildings
currently owned by The Irvine Company in the Irvine Spectrum area, (ii)
commercial, industrial and retail buildings in the future owned by The Irvine
Company in the Irvine Spectrum, and (iii) under certain circumstances in The
Irvine Company's discretion, similar buildings located in the Additional Areas
and other locations in California.
 
    The License Agreement requires FWOC to pay The Irvine Company a license fee
each calendar quarter, subject to an annual CPI increase that will not be less
than 2% or greater than 6%. The license fee will increase or decrease in the
future based on the rentable square footage of the buildings that are from time
to time subject to the License Agreement.
 
    The License Agreement provides FWOC with the right to install, maintain,
operate, replace and remove Cable and associated communications equipment
(Equipment) in, as well as access rights to, such buildings, subject to the
rights of The Irvine Company's tenants and to reasonable requirements and
procedures imposed by The Irvine Company. Except with respect to buildings that
are leased to a single tenant, The Irvine Company is required to provide FWOC
with a reasonable amount of equipment room space in each building, sufficient to
enable FWOC to install Cable and Equipment and deliver services. FWOC's rights
to a building are non-exclusive, meaning that The Irvine Company can grant
similar licenses to other service providers. Although all the Cable becomes the
property of The Irvine Company upon termination of the License Agreement, FWOC
has the right to remove and retain ownership of the Equipment, subject to The
Irvine Company's election to purchase the Equipment at a price to be negotiated
by the parties.
 
    Subject to certain qualifications, FWOC will have the obligation to provide
telecommunications services to any tenant who wishes to subscribe with FWOC for
those services, and FWOC is required to install Cable and Equipment in that
tenant's building if FWOC owns or leases Conduit located within 1,000 feet of
that building. Under certain circumstances, FWOC may be required to provide
completion and performance bonds to The Irvine Company in connection with that
work.
 
    To the extent that FWOC provides fiber optic service to a building, it is
required to achieve and maintain standards of minimum reliability. Subject to
force majeure, if there is a system-wide failure to provide such service that
exceeds five consecutive days, The Irvine Company has the right to use the
network (and if necessary bring in an alternative service provider) and to
charge its costs to FWOC.
 
    Whenever FWOC is the first competitive access provider to a building, it is
required to install a building entrance conduit system (which connects the
building to the street access point) (a BECS), with a capacity equal to 200% of
the capacity required by FWOC to service the building. The Irvine Company can
grant other providers the right to use that BECS, but must pay or cause that
provider to pay FWOC 50% of FWOC's cost of installing the BECS, which costs are
subject to increase based on a CPI calculation. Where a BECS already exists, The
Irvine Company must make any excess capacity therein available to FWOC.

NOTE 13--ADDITIONAL SUBSEQUENT EVENTS
 
    On March 17, 1998, the Company received a firm, written commitment from
Spectra 3 and Enron to invest, pursuant to that certain option held by Spectra 3
and Enron as described in Note 12, an additional $20,000,000 in the aggregate
for the purchase of 6,666,666 shares of Series B common stock and related Series
B common stock warrants concurrently with the closing of a high yield debt
offering by the Company, provided that such offering is consummated on or before
April 20, 1998.
 
    On March 17, 1998, that certain management consulting services agreement
entered into by and among the Company and an affiliate of Spectra 3, as
described in Note 12, was amended, whereby the consulting fee payable by the
Company to the affiliate pursuant to such agreement was increased from $500,000
per annum to $620,000 per annum, retroactive to January 1, 1998.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--BASIS OF PRESENTATION
 
   
    The accompanying unaudited consolidated financial statements of FirstWorld
Communications, Inc. (the Company) have been prepared by Company management,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission. The unaudited consolidated financial statements include the
accounts and results of operations of the Company and its subsidiaries, all of
which are wholly-owned. All significant intercompany balances and transactions
have been eliminated. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations. However, in the opinion of Company management, the unaudited
consolidated financial statements include all adjustments, consisting only of
normal recurring adjustments, necessary to present fairly the Company's
financial position as of June 30, 1998, and the results of its operations and
its cash flows for the nine months ended June 30, 1997 and 1998 and for the
period from September 1, 1993 (inception) to June 30, 1998. These unaudited
consolidated financial statements should be read in conjunction with the audited
consolidated financial statements and notes thereto for the fiscal year ended
September 30, 1997, included elsewhere in this Prospectus.
    
 
   
NOTE 2--HIGH YIELD DEBT OFFERING AND ADDITIONAL EQUITY INVESTMENT
    
 
   
    On April 13, 1998, the Company completed (i) an offering of debt securities
pursuant to Rule 144A under the Securities Act of 1933, as amended (the Act) for
gross proceeds of $250,205,000 (the High Yield Debt Offering) and (ii) a $20
million private placement to Colorado Spectra 3, LLC, a Colorado limited
liability company (Spectra 3), and Enron Capital & Trade Resources Corp., a
Delaware corporation (Enron) (the Additional Equity Investment) pursuant to the
exercise of an existing option held by Spectra 3 and Enron.
    
 
   
    In the High Yield Debt Offering, the Company sold 470,000 units consisting
of 13% Senior Discount Notes due 2008 (the Notes) and warrants to purchase an
aggregate of 3,713,094 shares of the Company's Series B Common Stock. The Notes
will accrete in value through April 15, 2003 at a rate of 13% per annum,
compounded semi-annually, at which time $470.0 million in aggregate principal
amount at maturity will be outstanding. Cash interest will neither accrue nor be
payable prior to April 15, 2003. Thereafter, cash interest on the Notes will
accrue and will be payable semiannually in arrears on each April 15 and October
15, commencing October 15, 2003, at a rate of 13% per annum. The Company is not
required to make mandatory redemption or sinking fund payments with respect to
the Notes prior to maturity. The Notes are redeemable at the option of the
Company, in whole or in part, at any time on or after April 15, 2003, at a
premium declining to par on April 15, 2006, plus accrued and unpaid interest
through the date of redemption. In the event of a change in control, as defined
in the indenture governing the Notes, the holders of the Notes will have the
right to require the Company to purchase their Notes in an amount equal to 101%
of the aggregate principal amount at maturity or accreted value thereof, as
applicable, plus accrued and unpaid interest to the date of purchase. The
warrants issued in connection with the High Yield Debt Offering have an exercise
price of $0.01 per share, are exercisable at any time on or after the earlier to
occur of May 1, 1999, an initial public offering of the Company's common stock
or in the event of a change in control, and expire on April 15, 2008. The fair
value of these warrants at the time of grant, which was estimated by management
to be $15,001,000, has been recorded as a discount on the underlying debt and is
being amortized to interest expense using the effective interest method over the
period that the Notes are outstanding.

        NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
   
NOTE 2--HIGH YIELD DEBT OFFERING AND ADDITIONAL EQUITY INVESTMENT (CONTINUED)
    
   
    Pursuant to the Additional Equity Investment, the Company sold to each of
Spectra 3 and Enron 3,333,333 shares of Series B Common Stock and warrants to
purchase an additional 3,333,333 shares of Series B Common Stock. The aggregate
net proceeds of the High Yield Debt Offering and the Additional Equity
Investment were $260.7 million.
    
 
   
NOTE 3--DEBT EXTINGUISHMENT
    
 
   
    On September 16, 1997, the Company entered into a revolving credit facility
(the Credit Facility) with a syndicate of lenders (the Lenders) to provide
financing for the construction of telecommunication networks and for general
working capital purposes. The Company terminated the Credit Facility
concurrently with the closing of the High Yield Debt Offering and paid the
Lenders a $1,000,000 termination fee pursuant to the terms thereof. The Company
has recorded an extraordinary loss of approximately $4,700,000 associated with
such debt extinguishment in the quarter ending June 30, 1998, which loss is
inclusive of the aforementioned termination fee and the write-off of unamortized
debt discount and deferred financing costs.
    
 
   
NOTE 4--MARKETABLE SECURITIES
    
 
   
    Marketable securities consist principally of commercial paper with original
maturities of beyond three months but less than six months. The Company has
classified its marketable securities as held to maturity as management has the
intent and ability to hold those securities to maturity. Such securities are
stated at cost. The fair value of the Company's marketable securities
approximates the carrying value.
    
 
   
NOTE 5--REINCORPORATION
    
 
   
    Effective June 26, 1998, the Company changed its state of incorporation from
California to Delaware. In connection therewith, a par value equal to $.0001 per
share was assigned to each series of common and preferred stock. As a result,
the consolidated statement of stockholders' equity for the nine months ended
June 30, 1998 reflects a reclassification to additional paid-in capital for the
amounts in excess of par value.
    
 
   
NOTE 6--LONG DISTANCE CARRIER AGREEMENT
    
 
   
    The Company's contract with Sprint (the long distance agreement referenced
in the final paragraph of Note 8 to the Company's Audited Consolidated Financial
Statements), whereby the Company is committed to certain minimum service fees
was amended in June of 1998. Pursuant to such amendment, minimum fees under the
contract aggregate $37,500, $487,500 and $1,437,500 during the remainder of
fiscal 1998 and for fiscal 1999 and 2000, respectively.

                                    GLOSSARY
 
    ANALOG--A form of transmission employing a continuous electrical signal
(rather than a pulsed or digital system) that varies in frequency and amplitude.
 
    ATM (ASYNCHRONOUS TRANSFER MODE)--ATM is packet-based switching and
transmission technology used to transmit voice, data and video.
 
    BANDWIDTH--At any given level of compression, the amount of information
transportable over a link per unit of time. A single T1 circuit will carry up to
1,544,000 bits (or 1.544 megabits) per second.
 
    BIT--A bit is the basic unit of information, yes-or-no, on-or-off, 1-or-0 in
the binary (base 2) system which is the basis of digital computing. In contrast,
a voice telephone signal over a copper wire is analog, reflecting a continuous
range of vocal tone (frequency) and volume (amplitude).
 
    BROADBAND--Data streams of at least 1.544 megabits per second. Broadband
communications systems can transmit large quantities of voice, data and video by
way of digital or analog signals. Examples of broadband communications systems
include DS-3 systems, which can transmit 672 simultaneous voice conversations,
or a broadcast television station signal that transmits high resolution audio
and video signals into the home. Broadband connectivity is an essential element
for interactive multimedia applications.

connected to the central office switch, but four or five digit dialing is
permitted among the line group.
 
    CLEC (COMPETITIVE LOCAL EXCHANGE CARRIER)--A company that provides local
exchange services in competition with the incumbent local exchange carrier.
 
    CO-LOCATION--The ability of a CLEC to connect its network to the ILEC's
central offices. Physical co-location occurs when a CLEC places its network
connection equipment inside the ILEC's central offices. Virtual co-location is
an alternative to physical co-location pursuant to which the ILEC permits a CLEC
to connect its network to the ILEC's central offices on comparable terms, even
though the CLEC's network connection equipment is not physically located inside
the ILEC's central office.
 
    DEDICATED ACCESS SERVICES--A line which bypasses the ILEC local network to
connect end-user customers to long distance voice and data networks.
 
    DIALING PARITY--Dialing parity is one of the changes, required by the
Telecommunications Act, intended to level the competitive playing field. Dialing
parity when implemented will enable customers to dial only 1+ or 0+ for service
no matter which local or long distance carrier they choose.
 
    DIGITAL--A method of storing, processing and transmitting information
through the use of distinct electronic or optical pulses that represent the
binary code digits 0 and 1. Digital transmission and switching technologies
employ a sequence of these pulses to represent information as opposed to the
continuously variable analog signal. Digital transmission and switching
technologies offer a threefold improvement in speed and capacity over analog
techniques, allowing much more efficient and cost-effective transmission of
voice, video, and data.
 
    DS-0, DS-1, DS-3--Standard telecommunications industry digital signal
formats, which are distinguishable by bit rate (the number of binary digits (0
and 1) transmitted per second). DS-0 service has a bit rate of 64 kilobits per
second, DS-1 service has a bit rate of 1.544 megabits per second and DS-3
service has a bit rate of 45 megabits per second.
 
    DSL (DIGITAL SUBSCRIBER LINES)--DSL is a family of technologies for
high-speed data transmission over existing copper twisted pair wiring in the
telephone local loops. Asymmetric DSL ("ADSL"), provides transmission at speeds
of up to 8 Mbps and Very-high-bit-rate DSL ("VDSL") can provide transmission at
speeds of up to 52 Mbps. VDSL technology is still in development.

(i.e., bandwidth) of a circuit may be measured in "kilobits per second."
 
    LANS (LOCAL AREA NETWORKS)--The interconnection of computers for the purpose
of sharing files, programs and various devices such as work stations, printers
and high-speed modems. LANs may include dedicated computers or file servers that
provide a centralized source of shared files and programs. Most office computer
networks use a LAN to share files, printers, modems and other items. Where
computers are separated by greater distances, a Metropolitan Area Network (MAN)
or other Wide Area Network (WAN) may be used.
 
    LATAS (LOCAL ACCESS AND TRANSPORT AREAS)--The geographically defined areas
in which RBOCs were authorized by the MFJ to provide local exchange services.
These LATAs roughly reflect the population density of their respective states
(California has 11 LATAs while Wyoming has only one). There are 163 LATAs in the
United States. LATAs have one or more area codes and may cross state lines.
 
    LEC (LOCAL EXCHANGE CARRIER)--A company that provides local exchange
services; see ILEC and CLEC.
 
    MBPS--Megabits per second.
 
                                      A-2

(i.e. bandwidth) of a circuit may be measured in "megabits per second."
 
    MEGAPOP--A single physical location capable of providing local calling
services for multiple area codes. See "POPs."
 
    MFJ (MODIFIED FINAL JUDGMENT)--The MFJ was a settlement of an antitrust suit
reached in 1982 between AT&T and the Department of Justice which forced the
breakup of the old Bell System. This judgment, also known as the Divestiture of
AT&T, established seven separate RBOCs and enhanced the establishment of two
distinct segments of telecommunications service; local and long distance. This
laid the groundwork for intense competition in the long distance industry. The
MFJ has been superseded by the Telecommunications Act of 1996.
 
    MICROWAVE--A portion of the radio spectrum having radio waves that are
physically very short, ranging in length between about 30 cm and 0.3 cm and

    NARROWBAND--Data streams of less than 64 kilobits per second.
 
    NUMBER PORTABILITY--The ability of an end user to change local exchange or
long distance carriers while retaining the same telephone number. If number
portability does not exist, customers will have to change phone numbers when
they change carriers.
 
    PBX (PRIVATE BRANCH EXCHANGE)--A device located on the customer premises
that provides call routing capability.
 
    POPS (POINTS OF PRESENCE)--Locations where a carrier has installed
transmission equipment in a service area that serves as, or relays calls to, a

affiliates of the old AT&T or Bell system.
 
    RESALE--Resale by a provider of telecommunications services (such as a local
exchange carrier) of such services to other providers or carriers on a wholesale
or a retail basis.
 
    SONET (SYNCHRONOUS OPTICAL NETWORK)--A set of standards of optical
communications transmission systems that define the optical rates and formats,
signal characteristics, performance, management and maintenance information to
be embedded within the signals and the multiplexing techniques to be employed in
optical communications transmission systems. SONET facilitates the
interpretability of dissimilar vendors' equipment. SONET benefits business
customers by minimizing the equipment necessary for various telecommunications
applications and supports networking diagnostic and maintenance features.
 
    T1--Telecommunications industry standard data transfer rate of 1.544
megabits per second.
 
    TCP/IP (TRANSMISSION CONTROL PROTOCOL/INTERNET PROTOCOL)--A suite of network
protocols that allow computers with different architectures and operating system
software to communicate with other computers on the Internet.
 
    UNBUNDLED LOOP--Essentially the two-wire copper loop that runs from the
ILEC's central office to the customer's premises.
 
    UNBUNDLED NETWORK ELEMENTS--As a result of the Telecommunications Act of
1996, the ILECs were told to make all the different elements of their networks
available to competitors to lease on wholesale basis. Pursuant to this order,
the ILECs have had to divide their networks into 14 different elements and
allocate costs to them individually. One example of the significance of this
ruling is that if a CLEC has its own fiber backbone and its own switch, and only
needs the last mile connection from the central office to the customer premises,
it can lease that connection from the ILEC without paying for other network
elements that it does not need.
 
    WAN--Wide Area Network; see LAN.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The General Corporation Law of the State of Delaware (the "DGCL") permits a
Delaware corporation to indemnify officers, directors, employees and agents for
actions taken in good faith and in a manner they reasonably believed to be in,
or not opposed to, the best interests of the corporation, and with respect to
any criminal action, which they had no reasonable cause to believe was unlawful.
The DGCL also provides that a corporation may advance the expenses of defense
(upon receipt of a written undertaking to reimburse the corporation if it is
ultimately determined that such individual is not entitled to indemnification)
and must reimburse a successful defendant for expenses, including attorneys'
fees, actually and reasonably incurred. The DGCL further provides that
indemnification may not be made for any claim, issue or matter as to which a
person has been adjudged by a court of competent jurisdiction, after exhaustion
of all appeals therefrom, to be liable to the corporation, except only to the
extent a court determines that the person is entitled to indemnify for such
expenses that such court deems proper. The DGCL also permits a corporation to
purchase and maintain liability insurance for its directors and officers.
 
    The Company's Certificate of Incorporation and bylaws provide that the
Company shall, to the fullest extent permitted by Section 145 of the DGCL, as
the same may be amended and supplemented from time to time, indemnify all
directors and officers and all other persons whom it has authority to indemnify
under Section 145 of the DGCL. Such limitation of liability does not affect the
availability of equitable remedies such as injunctive relief or rescission.
FirstWorld has entered into indemnification agreements with its officers and
directors containing provisions which may require FirstWorld, among other
things, to indemnify the 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), and to
advance their expenses incurred as a result of any proceeding against them as to
which they could be indemnified. The Company maintains insurance on behalf of
its directors and officers, insuring them against liabilities that they may
incur in such capacities or arising out of such status.

ITEM 22.  UNDERTAKINGS.
 
   
    The undersigned registrant 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 1993;
    
 
   
        (ii) To reflect in the prospectus any facts or events arising after the
    effective date of the registration statement (or the most recent
    posteffective 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;
    
 
   
    (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 the time shall be deemed to be the initial bona
fide offering thereof;
    
 
   
    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering; and
    
 
                                      II-3
<PAGE>
   
    (4) If the registrant is a foreign private issuer, to file a posteffective
amendment to the registration statement to include any financial statements
required by Rule 3-19 of Regulation S-X at the start of any delayed offering or
throughout a continuous offering. Financial statements and information otherwise
required by Section 10(a)(3) of the Act need not be furnished, provided that the
registrant includes in the prospectus, by means of a post-effective amendment,
financial statements required pursuant to this paragraph and other information
necessary to ensure that all other information in the prospectus is at least as
current as the date of those financial statements. Notwithstanding the
foregoing, with respect to registration statements on Form F-3, a post-effective
amendment need not be filed to include financial statements and information
required by Section 10(a)(3) of the Act or Rule 3-19 of Regulation S-X if such
financial statements and information are contained in periodic reports filed
with or furnished to the Commission by the registrant pursuant to section 13 or
section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the Form F-3.
    
 
    The undersigned Registrant hereby undertakes that insofar as indemnification
for liabilities arising under the Securities Act of 1933, as amended (the
"Act"), may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions described under Item 20 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 Act and is, therefore, unenforceable. In the event that a
claim of 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 paid by a
director, officer or controlling person of the Registrant in the successful
defense of any action, suit or proceeding) is asserted against the Registrant 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

                        FIRSTWORLD COMMUNICATIONS, INC.


    FIRST:  The name of the corporation (hereinafter the "Corporation") 
is
                                       
                        FIRSTWORLD COMMUNICATIONS, INC.

         SECOND:   The address, including street, number, city and county, of 
the registered office of the Corporation in the State of Delaware is 1013 
Centre Road, City of Wilmington, County of New Castle; and the name of the 
registered agent of the Corporation in the State of Delaware is CSC The 
United States Corporation Company.

         THIRD:    The nature of the business and of the purposes to be 
conducted and promoted by the Corporation shall be to engage in any lawful 
act or activity for which corporations may be organized under the General 
Corporation Law of Delaware.

    FOURTH:

    (a)  This Corporation is authorized to issue two classes of shares, 
designated "Common Stock" and "Preferred Stock."  The total number of shares 
which this Corporation shall have authority to issue is 110,000,000.  The 
number of shares of Common Stock authorized to be issued is 100,000,000, of 
which 10,135,164 shall be designated Series A Common Stock and 89,864,836 
shall be designated Series B Common Stock.  The number of shares of Preferred 
Stock authorized to be issued is 10,000,000.  The par value of each share of 
Common Stock and of each share of Preferred Stock is $.0001.

    (b)  The Preferred Stock may be issued from time to time in one or more 
series.  The Board of Directors of this Corporation is hereby authorized 
within the restrictions stated in these Amended and Restated Articles of 
Incorporation to fix the number of shares of each such series and determine 
the designation thereof and to (i) determine or alter the rights, preferences 
and restrictions imposed upon any wholly unissued series of Preferred Stock 
and (ii) increase or decrease the number of shares of that series, but not 
below the number of shares of any series then outstanding.  In case the 
number of shares of any series shall be so decreased, the shares constituting 
such decrease shall resume the status which they had prior to the adoption of 
the resolution originally fixing the number of shares of such series.

    1.   Voting Rights.

    (a)  Series A Common Stock.  Each holder of shares of Series A Common 
Stock shall be entitled to ten votes per share of Series A Common Stock held 
by such holder; and

    (b)  Series B Common Stock.  Each holder of shares of Series B Common 
Stock shall be entitled to one vote per share of Series B Common Stock held 
by such holder; and

<PAGE>

    (c)  Election of Directors.  From and after 1998, the holders of Series B 
Common Stock shall be entitled, voting as a separate class, to elect one (1) 
director of the Corporation at each election of directors.  Any vacancy 
occurring because of the death, resignation or removal of a director elected 
by holders of Series B Common  Stock shall be filled by the vote or written 
consent of the holders of a majority of the shares of Series B Common Stock 
or, in the absence of such action by such holders, by action of the remaining 
directors then in office.  All directors not elected as provided above shall 
be elected by the holders of Series A Common Stock and Series B Common Stock, 
voting together and not as separate classes, with each share voting as 
provided in this Article FOURTH, Section 1.  Any vacancy with respect to such 
directors shall be filled as provided in the Bylaws of the Corporation.

    2.   Conversion.

    (a)  Right to Convert.  Each holder of Series A Common Stock shall have 
the right to convert each share of Series A Common Stock held by such holder 
into one fully paid and non-assessable share of Series B Common Stock in 
accordance with this Article FOURTH, Section 2.

    (b)  Mechanics of Voluntary Conversion.  In order to exercise the 
conversion privilege, the holder of any shares of Series A Common Stock to be 
converted shall present and surrender the certificate or certificates 
representing such shares during usual business hours at the office or agency 
maintained by the Corporation for the transfer of Series A Common Stock and 
shall give written notice to the Corporation at such office or agency that 
the holder elects to convert the shares of Series A Common Stock represented 
by such certificate or certificates, to the extent specified in such notice.  
Such notice shall also state the name or names (with addresses) in which the 
certificate or certificates for shares of Series B Common Stock which shall 
be issuable on such conversion shall be issued.  If required by the 
Corporation, any certificate for shares of Series A Common Stock surrendered 
for conversion shall be accompanied by instruments of transfer, in form 
satisfactory to the Corporation, duly executed by the holder of such shares 
or his or her duly authorized representative.  As promptly as practicable 
after the receipt of such notice and the surrender of the certificate or 
certificates representing such shares of Series A Common Stock as aforesaid, 
the Corporation shall issue and deliver at such office or agency to such 
holder, or on his or her written order, a certificate or certificates for the 
number of full shares of Series B Common Stock issuable upon the conversion 
of such shares.  Each conversion of shares of Series A Common Stock shall be 
deemed to have been effected on the date on which such notice shall have been 
received by the office or agency maintained by the Corporation for such 
purpose and the certificate or certificates representing such shares shall 
have been surrendered (subject to receipt by such office or agency within 
thirty (30) days thereafter of any required instruments of transfer as 
aforesaid), and the person or persons in whose name or names any certificate 
or certificates for shares of Series B Common Stock shall be issuable upon 
such conversion shall be deemed to have become on said date the holder or 
holders of record of the shares represented thereby.

    (c)  Automatic Conversion.  Each share of Series A Common 
Stock shall be converted automatically into one share of Series B 
Common Stock upon the sale or transfer of such share of Series A 
Common Stock (other than the original sale and issuance by the 
Corporation) to any person or entity other than a Permitted 
Transferee (as defined below), an Affiliate (as defined below) of 
Donald L. Sturm or an Affiliate of Enron Capital & Trade 
Resources Corp. or, with respect to shares of Series A Common 
Stock held by Colorado Spectra 3, LLC, upon the transfer of a 
controlling interest in Colorado Spectra 3, LLC to any person or 
entity other than Enron Capital & Trade Resources Corp., Donald 
L. Sturm, a Permitted Transferee or one of their Affiliates.  A 
"Permitted Transferee" shall mean a natural person 

                                       2
<PAGE>

and who is a member, manager or officer of Colorado Spectra 3, LLC or an 
Affiliate of any such member, manager or officer.  An "Affiliate" of an 
entity or natural person shall mean (i) an entity or natural person which or 
who, directly or indirectly, controls, is controlled by, or is under common 
control with such entity or natural person and (ii), as applied to a natural 
person, said person, a member of said person's Immediate Family, or the 
personal representative of such person.  "Immediate Family" shall mean a 
natural person's spouse, child, grandchild, parent, grandparent, or sibling.

         SEVENTH:  In furtherance and not in limitation of the powers

damages shall be eliminated to the fullest extent permissible under Delaware

    (b)  This Corporation is authorized to provide indemnification of agents 
(as defined in Section 145 of the Delaware General Corporation Law) through 
bylaw provisions, agreements with agents, vote of stockholders or 
disinterested directors or otherwise, in excess of the indemnification 
otherwise permitted by Section 145 of the Delaware General Corporation Law.

    (c)  Any repeal or modification of this Article EIGHTH shall be 
prospective and shall not affect the rights of indemnification or limitation 
of liability in effect at the time of the alleged occurrence of any act or 
omission to act giving rise to liability or indemnification.

         NINTH:    The Corporation shall, to the fullest extent permitted by 
Section 145 of the General Corporation Law of the State of Delaware, as the 
same may be amended and supplemented, indemnify any and all persons whom it 
shall have power to indemnify under said section from and against any and all 
of the expenses, liabilities or other matters referred to in or covered by 
said section, and the indemnification provided for herein shall not be deemed 
exclusive of any other rights to which those indemnified may be entitled 
under any By-Law, agreement, vote of stockholders or disinterested directors 
or otherwise, both as to action in his official capacity and as to action in 
another capacity while holding such office, and shall continue as to a person 
who has ceased to be a director, officer, employee or agent and shall inure 
to the benefit of the heirs, executors and administrators of such person.

                              MEETINGS OF STOCKHOLDERS

     Section 1. Place of Meetings.  Meetings of stockholders shall be held 
at any place within or outside the State of Delaware designated by the Board 
of Directors.  In the absence of any such designation, stockholders' meetings 
shall be held at the principal executive office of the corporation.

     Section 2.  Annual Meeting of Stockholders.  The annual meeting of 
stockholders shall be held each year on a date and a time designated by the

of the stock issued and outstanding and entitled to vote at any meeting of 
stockholders, the holders 

<PAGE>

of which are present in person or represented by 
proxy, shall constitute a quorum for the transaction of business except as 
otherwise provided by law, by the Certificate of Incorporation, or by these 
By-Laws.  A quorum, once established, shall not be broken by the withdrawal 
of enough votes to leave less than a quorum and the votes present may 
continue to transact business until adjournment.  If, however, such quorum 
shall not be present or represented at any meeting of the stockholders, a 
majority of the voting stock represented in person or by proxy may adjourn 
the meeting from time to time, without notice other than announcement at the 
meeting, until a quorum shall be present or represented.  At such adjourned 
meeting at which a quorum shall be present or represented, any business may 
be transacted which might have been transacted at the meeting as originally 
notified.  If the adjournment is for more than thirty days, or if after the 
adjournment a new record date is fixed for the adjourned meeting, a notice of 
the adjourned meeting shall be given to each stockholder of record entitled 
to vote thereat.

     Section 4.  Voting.  When a quorum is present at any meeting, the vote 
of the holders of a majority of the stock having voting power present in 
person or represented by proxy shall decide any question brought before such 
meeting, unless the question is one upon which by express provision of the 
statutes, or the Certificate of Incorporation, or these By-Laws, a different 
vote is required in which case such express provision shall govern and 
control the decision of such question.

     Section 5.  Proxies.  At each meeting of the stockholders, each 
stockholder having the right to vote may vote in person or may authorize 
another person or persons to act for him by proxy appointed by an instrument 
in writing subscribed by such stockholder and bearing a date not more than 
three years prior to said meeting, unless said instrument provides for a 
longer period.  All proxies must be filed with the Secretary of the 
corporation at the beginning of

                                     2

<PAGE>

each meeting in order to be counted in any vote at the meeting.  Each 
stockholder shall have one vote for each share of stock having voting power, 
registered in his name on the books of the corporation on the record date set 
by the Board of Directors as provided in Article V, Section 6 hereof.  All 
elections shall be had and all questions decided by a plurality vote, except 
as otherwise expressly provided for herein.

     Section 6. Special Meetings.  Special meetings of the stockholders, for 
any purpose, or purposes, unless otherwise prescribed by statute or by the 
Certificate of Incorporation, may be called by the Chairman of the Board, the 
President or by one or more stockholders holding shares in the aggregate 
entitled to cast not less than 10% of the votes at any such special meeting 
and shall be called by the President or the Secretary at the request in 
writing of the Board of Directors.  Business transacted at any special 
meeting of stockholders shall be limited to the purposes stated in the notice.

     Section 7. Notice of Stockholder's Meetings.  Whenever stockholders are 
required or permitted to take any action at a meeting, a written notice of 
the meeting shall be given which notice shall state the place, date and hour 
of the meeting, and, in the case of a special meeting, the purpose or 
purposes for which the meeting is called.  The written notice of any meeting 
shall be given to each stockholder entitled to vote at such meeting not less 
than ten nor more than sixty days before the date of the meeting.  If mailed, 
notice is given when deposited in the United States mail, postage prepaid, 
directed to the stockholder at his address as it appears on the records of 
the corporation.  To be properly brought before the meeting, business must be 
of a nature that is appropriate for consideration at a meeting of 
stockholders and must be (i) specified in the notice of meeting (or any 
supplement thereto) given by or at the direction of the Board of Directors,

before the meeting by a stockholder.  In addition to any other applicable 
requirements, for business to be properly brought before a stockholder's 
meeting by a stockholder, the stockholder must have given timely notice 
thereof in writing to the Secretary of the Corporation. To be timely, each

     Notwithstanding anything in these By-Laws to the contrary, no business 
shall be transacted at an annual meeting except in accordance with the 
procedures set forth in this section; provided, however, that nothing in this 
section shall be deemed to preclude discussion by any stockholder of any 
business properly brought before an annual meeting in accordance with these 
By-Laws.

     Section 8. Maintenance and Inspection of Stockholder List.  The officer 
who has charge of the stock ledger of the corporation shall prepare and make,

shares registered in the name of each stockholder.  Such list shall be open 
to the examination of any stockholder, for any purpose germane to the 
meeting, during ordinary business hours, for a period of at least ten days 
prior to the meeting, either at a place within the city where the meeting is 
to be held, which place shall be specified in the notice of the meeting, or, 
if not so specified, at the place where the meeting is to be held.  The list

                                      DIRECTORS

     Section 1.   The Number of Directors.  The number of directors which 
shall constitute the whole Board shall be not less than three (3) nor more 
than eleven (11).  The actual number of directors shall be fixed from time to 
time by the Board as provided in the Certificate of Incorporation.  The 
directors need not be stockholders.  The directors shall be elected at the 
annual meeting of the stockholders, except as provided in Section 2 of this 
Article, and each director elected shall hold office until his successor is 
elected and qualified; provided, however, that unless otherwise restricted by 
the Certificate of Incorporation or by law, any director or the entire Board 
of Directors may be removed, for cause, from the Board of Directors at any 
meeting of stockholders by not less than 66 2/3% of the outstanding stock of

     Section 2.  Vacancies.  Vacancies on the Board of Directors by reason of 
death, resignation, retirement, disqualification, removal from office, or 
otherwise, and newly created directorships resulting from any increase in the 
authorized number of directors may be filled by a majority of the directors 
then in office, although less than a quorum, or by a sole remaining director. 
 The directors so chosen shall hold office until the next annual election of 
directors and until their successors are duly elected and shall qualify, 
unless sooner displaced.  If there are no directors in office, then an 
election of directors may be held in the manner provided by statute.  If, at 
the time of filling any vacancy or any newly created directorship, the 
directors then in office shall constitute less than a majority of the whole 
Board (as constituted immediately prior to any such increase), the Court of 
Chancery may, upon application of any stockholder or stockholders holding at 
least ten percent of the total number of the shares at the time outstanding 
having the right to vote for such directors, summarily order an election to 
be held to fill any such vacancies or newly created directorships, or to 
replace the directors chosen by the directors then in office.

   Section 3.  Powers.  The property and business of the corporation shall be 
managed by or under the direction of its Board of Directors.  In addition to 
the powers and authorities by these By-Laws expressly conferred upon them, 
the Board may exercise all such powers of the corporation and do all such 
lawful acts and things as are not by statute or by the Certificate of 
Incorporation or by these By-Laws directed or required to be exercised or 
done by the stockholders.

majority of the directors present at any meeting at which there is a quorum,
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute, by the Certificate of Incorporation or by
these By-Laws.  If a quorum shall not be present at any meeting of the Board of
Directors the directors present thereat may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.  If only one director is authorized, such sole director shall

permitted to be taken at any meeting of the Board of Directors or of any
committee thereof may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent thereto in writing, and the writing or
writings are filed with the minutes of proceedings of the Board or committee.

     Section 9.  Telephonic Meetings.  Unless otherwise restricted by
the Certificate of Incorporation or these By-Laws, members of the Board of
Directors, or any committee designated by the Board of Directors, may

                    COMMITTEES OF DIRECTORS

     Section 10.  Committees of Directors.  The Board of Directors may,
by resolution passed by a majority of the whole Board, designate one or more
committees, each such committee to consist of one or more of the directors of
the corporation.  The Board may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee.  In the absence or disqualification of a member of
a committee, the member or members thereof present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member.  Any such
committee, to the extent provided in the resolution of the Board of Directors,
shall have and may exercise all the powers and authority of the Board of
Directors in the management of the business and affairs of the corporation, and
may authorize the seal of the corporation to be affixed to all papers which may
require it; but no such committee shall have the power or authority in reference
to amending the Certificate of Incorporation, adopting an agreement of merger or
consolidation, recommending to the stockholders the sale, lease or exchange of
all or substantially all of the corporation's property and assets, recommending
to the stockholders a dissolution of the corporation or a revocation of a
dissolution, or amending the By-Laws of the corporation; and, unless the
resolution or the Certificate of Incorporation expressly so provide, no such
committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock.

     Section 11.  Minutes of Committee Meetings.  Each committee shall
keep regular minutes of its meetings and report the same to the Board of
Directors when required.

                              COMPENSATION OF DIRECTORS

     Section 12. Compensation of Directors.  Unless otherwise restricted by 
the Certificate of Incorporation or these By-Laws, the Board of Directors 
shall have the authority to fix the compensation of directors.  The directors 
may be paid their expenses, if any, of attendance at each meeting of the 
Board of Directors and may be paid a fixed sum for attendance at each meeting 
of the Board of Directors or a stated salary as director.  No such payment 
shall preclude any director from serving the corporation in any other 
capacity and receiving compensation therefor.  Members of special or standing 
committees may be allowed like compensation for attending committee meetings.

                                   INDEMNIFICATION

     Section 13. Indemnification. (a)  The corporation shall indemnify any 
person who was or is a party or is threatened to be made a party to any 
threatened, pending or completed action, suit or proceeding, whether civil, 
criminal, administrative or investigative (other than an action by or in the 
right of the corporation) by reason of the fact that he is or was a director, 
officer, employee or agent of the corporation, or is or was serving at the 
request of the corporation as a director, officer, employee or agent of 
another corporation, partnership, joint venture, trust or other enterprise, 
against expenses (including attorneys' fees), judgments, fines and amounts 
paid in settlement actually and reasonably incurred by him in connection with 
such action, suit or proceeding if he acted in good faith and in a manner he 
reasonably believed to be in or not opposed to the best interests of the 
corporation, and, with respect to any criminal action or proceeding, had no 
reasonable cause to believe his conduct was unlawful.  The termination of any 
action, suit or proceeding by judgment, order, settlement, conviction, or 
upon a plea of nolo contendere or its equivalent, shall not, of itself, 
create a presumption that the

                                     10
<PAGE>

person did not act in good faith and in a manner which he reasonably believed 
to be in or not opposed to the best interests of the corporation, and, with 
respect to any criminal action or proceeding, had reasonable cause to believe 
that his conduct was unlawful.

    (b)  The corporation shall indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor by reason of the fact that he is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation except that no such indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the Court of Chancery of Delaware or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which such Court
of Chancery or such other court shall deem proper.

    (c)  To the extent that a director, officer, employee or agent of the
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, he shall 

                                     11

<PAGE>

be indemnified against expenses (including attorneys' fees) actually and 
reasonably incurred by him in connection therewith.

     (d)  Any indemnification under paragraphs (a) and (b) (unless ordered by 
a court) shall be made by the corporation only as authorized in the specific 
case upon a determination that indemnification of the director, officer, 
employee or agent is proper in the circumstances because he has met the 
applicable standard of conduct set forth in paragraphs (a) and (b).  Such 
determination shall be made (1) by the Board of Directors by a majority vote 
of a quorum consisting of directors who were not parties to such action, suit 
or proceeding, or (2) if such a quorum is not obtainable, or, even if 
obtainable a quorum of disinterested directors so directs, by independent 
legal counsel in a written opinion, or (3) by the stockholders.

     (e)  Expenses incurred by an officer or director in defending any civil 
or criminal, administrative or investigative action, suit or proceeding shall 
be paid by the corporation in advance of the final disposition of such 
action, suit or proceeding upon receipt of an undertaking by or on behalf of 
such director or officer to repay such amount if it shall ultimately be 
determined that he is not entitled to be indemnified by the corporation as 
authorized in this Section 13.  Such expenses incurred by other employees and 
agents may be so paid upon such terms and conditions, if any, as the Board of 
Directors deems appropriate.

     (f)  The indemnification and advancement of expenses provided by, or 
granted pursuant to, the other paragraphs of this Section 13 shall not be 
deemed exclusive of any other rights to which those seeking indemnification 
or advancement of expenses may be entitled under any by-law, agreement, vote 
of stockholders or disinterested directors or otherwise, both as to action in 
his official capacity and as to action in another capacity while holding such 
office.

     (g)  The Board of Directors may authorize, by a vote of a majority of a 
quorum of the Board of Directors, the corporation to purchase and maintain 
insurance on behalf of any person who is or was a director, officer, employee 
or agent of the corporation, or is or was serving at the request of the 
corporation as a director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise against any liability 
asserted against him and incurred by him in any such capacity, or arising out 
of his status as such, whether or not the corporation would have the power to 
indemnify him against such liability under the provisions of this Section 13.

     (h)  For the purposes of this Section 13, references to "the 
corporation" shall include, in addition to the resulting corporation, any 
constituent corporation (including any constituent of a constituent) absorbed 
in a consolidation or merger which, if its separate existence had continued, 
would have had power and authority to indemnify its directors, officers, and 
employees or agents, so that any person who is or was a director, officer, 
employee or agent of such constituent corporation, or is or was serving at 
the request of such constituent corporation as a director, officer, employee 
or agent of another corporation, partnership, joint venture, trust or other 
enterprise, shall stand in the same position under the provisions of this 
Section with respect to the resulting or surviving corporation as he would 
have with respect to such constituent corporation if its separate existence 
had continued.

     (i)  For purposes of this section, references to "other enterprises" 
shall include employee benefit plans; references to "fines" shall include any 
excise taxes assessed on a person with respect to an employee benefit plan; 
and references to "serving at the request of the corporation" shall include 
service as a director, officer, employee or agent of the corporation

                                    13

<PAGE>

which imposes duties on, or involves services by, such director, officer, 
employee or agent with respect to an employee benefit plan, its participants 
or beneficiaries; and a person who acted in good faith and in a manner he 
reasonably believed to be in the interest of the participants and 
beneficiaries of an employee benefit plan shall be deemed to have acted in a 
manner "not opposed to the best interests of the corporation" as referred to 
in this section.

     (j)  The indemnification and advancement of expenses provided by, or 
granted pursuant to, this Section 13 shall, unless otherwise provided when 
authorized or ratified, continue as to a person who has ceased to be a 
director, officer, employee or agent and shall inure to the benefit of the 
heirs, executors and administrators of such a person.

                  FirstWorld Communications, Inc.
                  File No. 333-57829


Ladies and Gentlemen:

    In connection with the registration of $470,000,000 in aggregate 
principal amount at maturity of its 13% Senior Discount Notes due 2008 (the 
"Exchange Notes") by FirstWorld Communications, Inc., a Delaware corporation 
(the "Company"), pursuant to a registration statement on Form S-4 (the 
"Registration Statement") filed with the Securities and Exchange Commission 
(the "Commission") on June 26, 1998 (File No. 333-57829), as amended by 
Amendment No. 1 filed August 21, 1998, you have requested our opinion with 
respect to the matters set forth below. The Exchange Notes will be issued 
pursuant to an indenture (the "Indenture"), dated as of April 13, 1998, 
between the Company and The Bank of New York, as trustee (the "Trustee"). The 
Exchange Notes will be issued in exchange for the Company's outstanding 13% 
Senior Discount Notes due 2008 (the "Private Notes") on the terms set forth 
in the prospectus contained in the Registration Statement and the Letter of 
Transmittal filed as an exhibit thereto (the "Exchange Offer").

    In our capacity as your counsel, we have made such legal and factual 
examinations and inquiries as we have deemed necessary or appropriate for 
purposes of this opinion.

    In our examination, we have assumed the genuineness of all signatures, 
the authenticity of all documents submitted to us as originals and the 
conformity to authentic original documents of 

<PAGE>

all documents submitted to us as copies.  As to facts material to the 
opinions, statements and assumptions expressed herein, we have, with your 
consent, relied upon oral or written statements and representations of 
officers and other representatives of the Company and others.

    We are opining herein as to the effect on the subject transaction only of 
the federal laws of the United States, the internal laws of the State of New 
York and the General Corporation Law of the State of Delaware and we express 
no opinion with respect to the applicability thereto, or the effect thereon, 
of the laws of any other jurisdiction or, in the case of Delaware, any other 
laws, or as to any matters of municipal law or the laws of any other local 
agencies within any state.

    Subject to the foregoing and the other matters set forth herein, it is 
our opinion that, as of the date hereof:

    When the Exchange Notes to be exchanged for the Private Notes pursuant to 
the Exchange Offer have been duly executed, issued and authenticated in 
accordance with the terms of the Exchange Offer and the Indenture, the 
Exchange Notes will be legally valid and binding obligations of the Company, 
enforceable against the Company in accordance with their terms. 

    The opinion rendered in the foregoing paragraph relating to the 
enforceability of the Exchange Notes is subject to the following exceptions, 
limitations and qualifications: (i) the effect of bankruptcy, insolvency, 
reorganization, moratorium or other similar laws now or hereafter in effect 
relating to or affecting the rights and remedies of creditors; (ii) the 
effect of general principles of equity, whether enforcement is considered in 
a proceeding in equity or at law, and the discretion of the court before 
which any proceeding therefor may be brought; (iii) the unenforceability 
under certain circumstances under law or court decisions of provisions 
providing for the indemnification of or contribution to a party with respect 
to a liability where such indemnification or contribution is contrary to 
public policy; (iv) we express no opinion concerning the enforceability of 
the waiver of rights or defenses contained in Section 6.11 of the Indenture; 
and (v) we express no opinion with respect to whether acceleration of the 
Exchange Notes may affect the collectibility of that portion of the stated 
principal amount thereof which might be determined to constitute unearned 
interest thereon.

    To the extent that the obligations of the Company under the Indenture and 
the Exchange Notes may be dependent upon such matters, we have assumed for 
purposes of this opinion that (i) the Trustee is (a) duly organized, validly 
existing and in good standing under the laws of its jurisdiction of 
organization; (b) has the requisite organizational and legal power and 
authority to perform its obligations under the Indenture; (c) is duly 
qualified to engage in the activities contemplated by the Indenture; and (d) 
has duly authorized, executed and delivered the Indenture; (ii) the Indenture 
is the legally valid and binding agreement of the Trustee, enforceable 
against the Trustee in accordance with its terms; (iii) that the Trustee is 
in compliance, generally and with respect to acting as Trustee under the 
Indenture, with all applicable laws and regulations; and (iv)

the Trustee has complied with any applicable requirement to file returns and 
pay taxes under the Franchise Tax law of the State of California.

    We have not been requested to express and, with your knowledge and 
consent, do not render any opinion with respect to the applicability to the 
obligations of the Company under the Indenture and the Exchange Notes of 
Sections 547 and 548 of Title 11 of the Bankruptcy Reform Act of 1978, as 
amended, or applicable state law (including, without limitation, Article 10 
of the New York Debtor & Creditor Law) relating to fraudulent transfers and 
obligations.

    We consent to your filing this opinion as an exhibit to the Registration 
Statement and to the reference to our firm contained under the heading "Legal 
Matters."

                                    Very truly yours,

                                 FORM OF

                         INDEMNIFICATION AGREEMENT

   This Indemnification Agreement is made as of the ___ day of ________, 
_____ (the "Agreement"), by and between FirstWorld Communications, Inc., a 
Delaware corporation (the "Company"), and the undersigned [Officer/Director] 
of the Company (the "Indemnitee"), with reference to the following facts:

   The Indemnitee is currently serving as an [Officer/Director] of the 
Company and the Company wishes the Indemnitee to continue in such capacity. 
The Indemnitee is willing, under certain circumstances, to continue serving 
as an [Officer/Director] of the Company. 

   The Indemnitee has indicated that he does not regard the indemnities 
available under the Company's By-Laws as adequate to protect him against the 
risks associated with his service to the Company and has noted that the 
Company's directors' and officers' liability insurance policy has numerous 
exclusions and a deductible and thus does not adequately protect Indemnitee.  
In this connection the Company and the Indemnitee now agree they should enter 
into this Agreement in order to provide greater protection to Indemnitee 
against such risks of service to the Company. 

   Section 145 of the General Corporation Law of the State of Delaware, under 
which Law the Company is organized, empowers corporations to indemnify a 
person serving as a director, officer, employee or agent of the corporation 
and a person who serves at the request of the corporation as a director, 
officer, employee or agent of another corporation, partnership, joint 
venture, trust, or other enterprise, and said Section 145 and the By-Laws of 
the Company specify that the indemnification set forth in said Section 145 
and in the By-Laws, respectively, shall not be deemed exclusive of any other 
rights to which those seeking indemnification may be entitled under any 
By-Law, agreement, vote of stockholders or disinterested directors or 
otherwise. 


<PAGE>

   In order to induce the Indemnitee to continue to serve as an 
[Officer/Director] of the Company and in consideration of his continued 
service, the Company hereby agrees to indemnify the Indemnitee as follows: 

   1. Indemnity.  The Company will indemnify the Indemnitee, his 
executors, administrators or assigns, for any Expenses (as defined below) 
which the Indemnitee is or becomes legally obligated to pay in connection 
with any Proceeding (as defined below).  As used in this Agreement the term 
"Proceeding" shall include any threatened, pending or completed claim, 
action, suit or proceeding, whether brought by or in the right of the Company 
or otherwise and whether of a civil, criminal, administrative or 
investigative nature, in which the Indemnitee may be or may have been 
involved as a party or otherwise, by reason of the fact that Indemnitee is or 
was a director or officer of the Company, by reason of any actual or alleged 
error or misstatement or misleading statement made or suffered by the 
Indemnitee, by reason of any action taken by him or of any inaction on his 
part while acting as such director or officer, or by reason of the fact that 
he was serving at the request of the Company as a director, trustee, officer, 
employee or agent of another corporation, partnership, joint venture, trust 
or other enterprise; provided, that in each such case Indemnitee acted in 
good faith and in a manner which he reasonably believed to be in or not 
opposed to the best interests of the Company, and, in the case of a criminal 
proceeding, in addition had no reasonable cause to believe that his conduct 
was unlawful.  As used in this Agreement, the term "other enterprise" shall 
include (without limitation) employee benefit plans and administrative 
committees thereof, and the term "fines" shall include (without limitation) 
any excise tax assessed with respect to any employee benefit plan. 

    2.  Expenses.  As used in this Agreement, the term "Expenses" shall 
include, without limitation, damages, judgments, fines, penalties, 
settlements and costs, attorneys' fees and 



                                       2

<PAGE>


disbursements and costs of attachment or similar bonds, investigations, and 
any expenses of establishing a right to indemnification under this Agreement. 

      3. Selection of Counsel.  In the event the Company shall be obligated 
hereby to pay the Expenses of any Proceeding against Indemnitee, the Company, 
if appropriate, shall be entitled to assume the defense of such Proceeding, 
with counsel approved by Indemnitee, which approval shall not be unreasonably 
withheld, upon the delivery to Indemnitee of written notice of its election 
so to.  After delivery of such notice, approval of such counsel by Indemnitee 
and the retention of such counsel by the Company, the Company will not be 
liable to Indemnitee under this Agreement for any fees of counsel 
subsequently incurred by Indemnitee with respect to the same Proceeding, 
provided that (i) Indemnitee shall have the right to employ his counsel in 
any such Proceeding at Indemnitee's expense; and (ii) if (A) the employment 
of counsel by Indemnitee has been previously authorized by the Company, (B) 
Indemnitee shall have reasonably concluded that there may be a conflict of 
interest between the Company and Indemnitee in the conduct of any such 
defense or (C) the Company shall not, in fact, have employed counsel to 
assume the defense of such Proceeding, then the fees and expenses of 
Indemnitee's counsel shall be at the expense of the Company. 

      4. Enforcement.  If a claim or request under this Agreement is not paid 
by the Company, or on its behalf, within thirty (30) days after a written 
claim or request has been received by the Company, the Indemnitee may at any 
time thereafter bring suit against the Company to recover the unpaid amount 
of the claim or request and if successful in whole or in part, the Indemnitee 
shall be entitled to be paid also the Expenses of prosecuting such suit.  The 
Company shall have the right to recoup from the Indemnitee the amount of any 
item or items of Expenses theretofore paid by the Company pursuant to this 
Agreement, to the extent such Expenses are not reasonable in nature or 
amounts; provided, however, that the Company shall 




                                       3

<PAGE>


have the burden of proving such Expenses to be unreasonable.  The burden of 
proving that the Indemnitee is not entitled to indemnification for any other 
reason shall be upon the Company.

      5. Subrogation.  In the event of payment under this Agreement, 
the Company shall be subrogated to the extent of such payment to all of the 
rights of recovery of the Indemnitee, who shall execute all papers required 
and shall do everything that may be necessary to secure such rights, 
including the execution of such documents necessary to enable the Company 
effectively to bring suit to enforce such rights. 

      6. Exclusions.  The Company shall not be liable under this Agreement to 
pay any Expenses in connection with any claim made against the Indemnitee: 

         (a)   to the extent that payment is actually made to the Indemnitee 
under a valid, enforceable and collectible insurance policy; 

         (b)   to the extent that the Indemnitee is indemnified and actually 
paid otherwise than pursuant to this Agreement; 

         (c)   in connection with a judicial action by or in the right of the 
Company, in respect of any claim, issue or matter as to which the Indemnitee 
shall have been adjudged to be liable for negligence or misconduct in the 
performance of his duty to the Company unless and only to the extent that any 
court in which such action was brought shall determine upon application that, 
despite the adjudication of liability but in view of all the circumstances of 
the case, the Indemnitee is fairly and reasonably entitled to indemnity for 
such expenses as such court shall deem proper; 

         (d)   if it is proved by final judgment in a court of law or other 
final adjudication to have been based upon or attributable to the 
Indemnitee's in fact having gained any personal profit or advantage to which 
he was not legally entitled; 

                                       4

<PAGE>


         (e)   for a disgorgement of profits made from the purchase and sale 
by the Indemnitee of securities pursuant to Section 16(b) of the Securities 
Exchange Act of 1934 and amendments thereto or similar provisions of any 
state statutory law or common law; 

         (f)   brought about or contributed to by the dishonesty of the 
Indemnitee seeking payment hereunder; however, notwithstanding the foregoing, 
the Indemnitee shall be protected under this Agreement as to any claims upon 
which suit may be brought against him by reason of any alleged dishonesty on 
his part, unless a judgment or other final adjudication thereof adverse to 
the Indemnitee shall establish that he committed (i) acts of active and 
deliberate dishonesty, (ii) with actual dishonest purpose and intent, (iii) 
which acts were material to the cause of action so adjudicated; or

         (g)   for any judgment, fine or penalty which the Company is 
prohibited by applicable law from paying as indemnity or for any other 
reason. 

      7. Indemnification of Expenses of Successful Party.  Notwithstanding 
any other provision of this Agreement, to the extent that the Indemnitee has 
been successful on the merits or otherwise in defense of any Proceeding or in 
defense of any claim, issue or matter therein, including dismissal without 
prejudice, Indemnitee shall be indemnified against any and all Expenses 
incurred in connection therewith. 

      8. Partial Indemnification.  If the Indemnitee is entitled under any 
provision of this Agreement to indemnification by the Company for some or a 
portion of Expenses, but not, however, for the total amount thereof, the 
Company shall nevertheless indemnify the Indemnitee for the portion of such 
Expenses to which the Indemnitee is entitled. 

      9. Advance of Expenses.  Expenses incurred by the Indemnitee in 
connection with any Proceeding, except the amount of any settlement, shall be 
paid by the Company in advance upon request of the Indemnitee that the 
Company pay such Expenses.  The Indemnitee hereby undertakes to repay to the 
Company the amount of any Expenses theretofore paid by the 

                                       5

<PAGE>

Company to the extent that it is ultimately determined that such Expenses 
were not reasonable or that the Indemnitee is not entitled to 
indemnification. 

      10. Approval of Expenses.  No Expenses for which indemnity shall be 
sought under this Agreement, other than those in respect of judgments and 
verdicts actually rendered, shall be incurred without the prior consent of 
the Company, which consent shall not be unreasonably withheld. 

      11.  Notice of Claim.  The Indemnitee, as a condition precedent to his 
right to be indemnified under this Agreement, shall give to the Company 
notice in writing as soon as practicable of any claim made against him for 
which indemnity will or could be sought under this Agreement.  Notice to the 
Company shall be given at its principal office and shall be directed to the 
Corporate Secretary (or such other address as the Company shall designate in 
writing to the Indemnitee); notice shall be deemed received if sent by 
prepaid mail properly addressed, the date of such notice being the date 
postmarked.  In addition, the Indemnitee shall give the Company such 
information and cooperation as it may reasonably require and as shall be 
within the Indemnitee's power. 

      12.   Notice to Insurers.  If, at the time of the receipt of a notice 
of a claim pursuant to Section 11 hereof, the Company has director and 
officer liability insurance in effect, the Company shall give prompt notice 
of the commencement of such proceeding to the insurers in accordance with the 
procedures set forth in the respective policies.  The Company shall 
thereafter take all necessary or desirable action to cause such insurers to 
pay, on behalf of the Indemnitee, all amounts payable as a result of such 
proceeding in accordance with the terms of such policies. 

      13.   Mutual Acknowledgment. Both the Company and Indemnitee 
acknowledge that in certain instances, Federal law or applicable public 
policy may prohibit the Company from indemnifying its directors and officers 
under this Agreement or otherwise.  Indemnitee 


                                       6

<PAGE>



understands and acknowledges that the Company has undertaken or may be 
required in the future to undertake with the Securities and Exchange 
Commission to submit the question of indemnification to a court in certain 
circumstances for a determination of the Company's right under public policy 
to indemnify Indemnitee.

      14.   Counterparts.  This Agreement may be executed in any number of 
counterparts, all of which taken together shall constitute one instrument. 

      15.   Indemnification Hereunder Not Exclusive.  Nothing herein shall be 
deemed to diminish or otherwise restrict the Indemnitee's right to 
indemnification under any provision of the Certificate of Incorporation or 
By-Laws of the Company and amendments thereto or under law. 

      16.   Governing Law.  This Agreement shall be governed by 
and construed in accordance with Delaware law. 

      17.   Saving Clause.  Wherever there is conflict between any provision 
of this Agreement and any applicable present or future statute, law or 
regulation contrary to which the Company and the Indemnitee have no legal 
right to contract, the latter shall prevail, but in such event the affected 
provisions of this Agreement shall be curtailed and restricted only to the 
extent necessary to bring them within applicable legal requirements. 

      18.   Coverage.  The provisions of this Agreement shall apply with 
respect to the Indemnitee's service as an [Officer/Director] of the Company 
prior to the date of this Agreement and with respect to all periods of such 
service after the date of this Agreement, even though the Indemnitee may have 
ceased to be an [Officer/Director] of the Company.

     number of shares owned by the Founders.

       (d) "Offered Stock" means all Stock proposed to be transferred 
     (other than by Exempt Transfer as defined below) by a Founder or Founders.

       (e) "Exempt Transfer" shall mean:

         transaction that creates a mere security interest; any transfer to any 
         Founder's ancestors, descendants or spouse or to trusts for the 
         benefit of such persons or the Founder; or any bona fide gift; 
         provided that the pledgee, transferee or donee shall enter into a 
         written agreement to be bound by and comply with all provisions of 
         this Agreement.  Such transferred stock shall remain "Stock" 
         hereunder, and such pledgee, transferee or donee shall be treated as 
          a "Founder" for purposes of this Agreement;

         which the Company is merged or consolidated with or into any other 
         entity and where the shareholders of the Company immediately prior to 
         the transaction own less than 50% of the outstanding voting securities 
         of the Company or the surviving entity immediately after the 
         transaction;

           (iii) Any transfer or transfers by a Founder to another Founder 
         ("Transferee-Founder") of the Company so long as the Transferee-Founder
         is, at the time of the transfer, employed by or acting as a consultant 
         or director of the Company; provided that the transferred stock shall 
         remain "Stock" hereunder.

           (iv) Any sale to the Company;

           (v) Any sale prior to which a Founder held less than 1% of the 
         Company's outstanding Common Stock; and

         aggregate, over the term of this Agreement amount to no more than ten 
         thousand (10,000) shares of Stock held by a Founder as of the date 
         hereof.

       (f) "Founder Pro Rata Share" shall be calculated as of the date of a 
     Selling Founder's Notice (as defined in Section 2.1) and shall be 
     determined by dividing:

           (i) The number of outstanding shares of Common Stock 
         Equivalents then held by each Founder other than the Selling Founder; 
         by

           (ii) The number of outstanding shares of Common Stock 
         Equivalents then held by all Founders other than the Selling Founder.

<PAGE>

       (g) "Major Investor Pro Rata Share" shall be calculated as of the 
     date of the Selling Founder's Notice and shall be determined by dividing:

           (i) The number of outstanding shares of Common Stock 
         Equivalents then held by each Major Investor; by

           (ii) The number of outstanding shares of Common Stock 
         Equivalents then held by all Major Investors.

       (h) "Major Investor Co-Sale Pro Rata Amount" shall be determined as 
     of the date of the Selling Founder's Notice set forth in Section 2.1 and 
     shall be determined by multiplying (x) the aggregate number of shares of 
     Offered Stock set forth in such Notice less the aggregate number of shares
     of Offered Stock with respect to which the Founder's Right of First Offer 
     has been exercised as provided in Section 2.2, by (y) a fraction (i) the 
     numerator of which is the number of outstanding shares of Common Stock 
     Equivalents then held by the Major Investor exercising the Major Investor 
     Co-Sale Right (defined in Section 3.1) and (ii) the denominator of which 
     is the aggregate number of the then outstanding shares of Common Stock 
     Equivalents owned of record by all of the Major Investors plus the number 
     of the then outstanding shares of Common Stock Equivalents owned of record
     by the Selling Founder.

                                   SECTION 2

                              RIGHT OF FIRST OFFER

   2.1 Notice of Proposed Transfer.  Before any Founder may sell or 
otherwise transfer (other than by an Exempt Transfer) any Offered Stock, such 
Founder (the "Selling Founder") must comply with the provisions of this 
Section 2 and of Section 3 below.  Such Founder must give at the same time to 
the Company, each of the other Founders and each of the Major Investors, a 
written notice signed by the Selling Founder (the "Selling Founder's Notice") 
stating (a) the Selling Founder's bona fide intention to transfer such 
Offered Stock; (b) the number and type of shares of the Offered Stock; (c) 
the bona fide cash price or, in reasonable detail, other consideration, per 
share for which the Selling Founder proposes to transfer such Offered Stock 
(the "Offered Price"); and (d) the name and address of the proposed third 
party purchaser(s) or transferee(s) of the Offered Stock ("Third Party 
Purchaser").

   2.2 Founder's Right of First Offer.

     (a) Founder's Pro Rata Rights.  Each Founder will have the Right of 
   First Offer to purchase up to such Founder's Pro Rata Share of the Offered 
   Stock as follows.  Any Founder desiring to purchase any or all of the 
   Offered Stock must, within the thirty (30) day period (the "Founder Refusal 
   Period") commencing on the date the Selling Founder's Notice is given by 
   the Selling Founder, give written notice to the Selling Founder and to the 
   Company of such Founder's election to purchase Offered Stock, and the number
   of shares of Offered Stock (which may be less than or, in accordance with 
   Section 2.3(b), more than such Founder's Pro Rata Share of the Offered 
   Stock) that the Founder desires to purchase.


                                       3

<PAGE>

     (b) Founder's Over-Allotment Rights.  If one or more Founders do not 
   elect to purchase their full Founder Pro Rata Share of the Offered Stock, 
   the portion that such Founders have not elected to purchase ("Excess Founder
   Shares") will be allocated to each Founder electing to purchase in excess 
   of his Founder Pro Rata Share of the Offered Stock ("Electing Founder") in 
   accordance with the amount of Excess Founder Shares such Electing Founder 
   is willing to purchase as set forth in his notice delivered in accordance 
   with Section 2.2(a).  Notwithstanding the preceding sentence, if there are 
   insufficient Excess Founder Shares such that an Electing Founder is unable 
   to purchase all of the Excess Founder Shares specified in his notice, the 
   Excess Founder Shares shall be allocated to each such Electing Founders up 
   to the number of Excess Founder Shares which such Electing Founder has 
   indicated that he is willing to purchase as set forth in his notice 
   delivered in accordance with Section 2.2(a), by multiplying the Excess 
   Founder Shares by a fraction, the numerator of which is the number of Common 
   Stock Equivalents then held by such Electing Founder, and the denominator of 
   which is the number of shares of Common Stock Equivalents then held by all 
   Electing Founders.  Any remaining Excess Founder Shares will be reallocated 
   among the remaining Electing Founders on the same basis as set forth in the 
   preceding sentence, on an iterative basis until all Excess Founders Shares 
   have been allocated.

   2.3 Major Investors Right of First Offer.

     (a) If following the exercise of the Founder Right of First Offer as 
   indicated in Section 2.2, there are shares of Offered Stock remaining that 
   are not subject to purchase by the Founders other than the Selling Founder, 
   the Selling Founder shall notify the Major Investors in writing of such 
   remaining Offered Stock and each Major Investor will have the Right of First 
   Offer to purchase up to such Major Investor's Pro Rata Share of such 
   remaining Offered Stock (including any Co-Sale Shares substituted for any 
   Remaining Offered Stock pursuant to Section 3) ("Remaining Offered Stock").  
   Any Major Investor desiring to purchase any or all of the Remaining Offered 
   Stock must, within the fifteen (15) day period (the "Major Investor Refusal 
   Period") commencing on the date the notice is given by the Selling Founder 
   pursuant to this Section 2.3(a), give written notice to the Selling Founder, 
   the other Major Investors and to the Company of such Major Investor's 
   election to purchase Remaining Offered Stock, and the number of shares of 
   Remaining Offered Stock (which may be less than or, in accordance with 
   Section 2.3(b), more than such Major Investor's Pro Rata Share of the 
   Offered Stock) that the Major Investor desires to purchase.

     (b) Major Investor Over-Allotment Rights.  To the extent that one or 
   more Major Investors do not exercise their right to purchase their full Major
   Investor Pro Rata Share of the Remaining Offered Stock, the portion that such
   Major Investors have not elected to purchase ("Excess Major Investor Shares")
   will be allocated to each Major Investor electing to purchase in excess of 
   its Major Investor Pro Rata Share of the Remaining Offered Stock ("Electing 
   Major Investor") in accordance with the number of Excess Major Investor 
   Shares such Major Investor has indicated it is willing to purchase as stated 
   in its notice delivered in accordance with Section 2.3(a).  Notwithstanding 
   the preceding sentence, if there are insufficient Excess Major Investor 
   Shares such that an Electing Major Investor is unable to purchase all of the 
   Excess Major 
   

                                       4

<PAGE>

   Investor Shares specified in its notice, the Excess Major Investor Shares 
   shall be allocated to each Electing Major Investor, up to the number of 
   Excess Major Investor Shares which such Major Investor has indicated it is 
   willing to purchase as stated in its notice delivered in accordance with 
   Section 2.3(a), by multiplying the Excess Major Investor Shares by a 
   fraction, the numerator of which is the number of multiplying the Excess 
   Major Investor Shares by a fraction, the numerator of which is the number 
   of Common Stock Equivalents then held by such Electing Major Investor and 
   the denominator of which is the number of shares of Common Stock Equivalents 
   then held by all Electing Major Investors.  Any remaining Excess Major 
   Investor Shares will be reallocated among the remaining Electing Major 
   Investors on the same basis as set forth in the preceding sentence, on an 
   iterative basis until all Excess Major Investor Shares have been allocated.

   2.4 Purchase Price.  The purchase price for the Offered Stock to be 
purchased by the Founders and Major Investors exercising their Right of First 
Offer under this Agreement will be the Offered Price, and will be payable as 
set forth in Section 2.5 hereof.

   2.5 Payment.  Payment of the purchase price for the Offered Stock 
purchased by the Founders exercising their Right of First Offer will be made 
within seven (7) days after the close of the Founder Refusal Period.  Payment 
of the purchase price for the Offered Stock purchased by the Major Investors 
exercising their Right of First Offer will be made within seven (7) days 
after the close of the Major Investor Refusal Period.  Payment of the 
purchase price will be made at the option of the Selling Founder (i) in cash, 
by check or by promissory note, (ii) by cancellation of indebtedness of the 
Selling Founder to such purchasing Founder or purchasing Major Investor, or 
(iii) by any combination of the foregoing.

   2.6 Selling Founder's Right to Transfer.  If the Founders and the Major 
Investors do not elect to purchase all of the Offered Stock, then, subject to 
Section 3, the Selling Founder may, not later than 120 days following 
delivery to the Company and each of the Major Investors of the Selling 
Founder's Notice, transfer that portion of the Offered Stock not purchased by 
the purchasing Founders or purchasing Major Investors, to any Third Party 
Purchaser named in the Selling Founder's Notice, on terms and conditions not 
more favorable to the Selling Founder than those described in the Selling 
Founder's Notice.  Any proposed transfer on terms and conditions more 
favorable to the Selling Founder than those described in the Selling 
Founder's Notice, as well as any subsequent proposed transfer of any Stock by 
the Selling Founder, shall again be subject to the Right of First Offer.  If 
the Offered Stock is transferred in accordance with the terms and conditions 
of this Agreement, then the transferee(s) of the Offered Stock (other than a 
Founder) will thereafter hold such Offered Stock free of the Right of First 
Offer and Co-Sale Right.  If the Offered Stock is not so transferred during 
such 120-day period, then the Selling Founder will not transfer any of such 
Offered Stock without complying again in full with the provisions of this 
Agreement.

                                   SECTION 3

                                 CO-SALE RIGHT

   3.1 Major Investor Co-Sale Right.  Prior to the Transfer of any of the 
Offered Stock to a Major Investor or a Third Party Purchaser, each Major 
Investor who has not exercised its Right of First Offer under Section 2 shall 
have a right to participate in the transfer of any Offered Stock to a Major 
Investor or a Third Party Purchaser ("Major Investor Co-Sale Right") to the 
extent of (but not to a greater extent than) such Major Investor's Co-Sale 
Pro Rata Amount.  Each Major Investor desiring to exercise the major Investor 
Co-Sale Right must, within the Major Investor Refusal Period, give written 
notice (the "Exercise Notice") to the Company and the Selling Founder of such 
Major Investor's exercise of the Major Investor Co-Sale Right.  The Major 
Investor shall specify in the Exercise Notice the number of shares (up to its 
Major Investor Co-Sale Pro Rata Amount) such Major Investor desires to sell.  
The Selling Founder shall inform each Major Investor of the decision of each 
other Major Investor promptly upon learning it.  The Major Investors agree to 
advise each other of their intentions under this Section 3 as soon as 
reasonably feasible after receiving the Selling Founder's Notice.

   3.2 Sale of Co-Sale Shares.

     (a) The Selling Founder shall assign to each Major Investor which 
   exercises its Right of Co-Sale hereunder as much of his interest in the 
   agreement of sale with the transferee as such Major Investor shall be 
   entitled to and shall accept hereunder.  To the extent that any transferee 
   prohibits such assignment or otherwise refuses to purchase shares or other 
   securities from a Major Investor exercising its Right of Co-Sale hereunder, 
   the Selling Founder shall not sell to such transferee any stock unless and 
   until, simultaneously with such sale, the Selling Founder shall purchase 
   such shares or other securities from such Major Investor for the same 
   consideration and on the same terms and conditions as the proposed transfer 
   described in the Selling Founder's Notice.

     (b) Each Major Investor which elects to exercise its Co-Sale Right 
   pursuant to Section 3.1 above shall effect its participation in the sale by 
   promptly delivering to the Selling Founder for transfer to the transferee 
   one or more certificates, properly endorsed for transfer, which represent:

           (i) the type and number of shares of stock which such Selling 
         Founder is selling; or

           (ii) that number of shares of Series C Preferred Stock which is 
         at such time convertible into the number of shares of Common Stock 
         which such Major Investor elects to sell; provided that if the 
         transferee objects to the delivery of Series C Preferred Stock in lieu 
         of Common Stock, such Major Investor shall convert such Series C 
         Preferred Stock into Common Stock and deliver Common Stock as provided 
         in this Section 3.2(b).  The Founders agree to take such actions as may
         be necessary to cause the Company to make any such conversion 
         concurrent with the actual transfer of shares of Co-Sale Shares to 
         the transferee.


                                       6

<PAGE>

   The stock certificate or certificates that the Major Investor delivers to 
the Selling Founder as provided above shall be transferred to the transferee 
in consummation of the sale of the Co-Sale Shares pursuant to the terms and 
conditions specified in the Exercise Notice, and the Selling Founder shall 
concurrently therewith remit to the participating Major Investor that portion 
of the sale proceeds to which such Major Investor is entitled by reason of 
its participation in such sale.

   3.3 Transfer of Shares Upon Failure to Exercise Right of Co-Sale.  If 
none of the Major Investors elects to exercise the Co-Sale Right with respect 
to the offered Stock, the Selling Founder may, not later than 120 days 
following delivery to the Company and each of the Major Investors of the 
Selling Founder's Notice conclude a transfer of the Offered Stock on terms 
and conditions not more favorable to the Selling Founder than those described 
in the Selling Founder's Notice.  Any proposed transfer on terms and 
conditions more favorable to the Selling Founder than those described in the 
Selling Founder's Notice, as well as any subsequent proposed transfer of any 
Stock by the Selling Founder, shall again be subject to the Right of Co-Sale.

                                   SECTION 4

                              ADDITIONAL PROVISIONS

   4.1 Termination.  The rights of the Major Investors (and each Major 
Investor individually) under this Agreement shall terminate upon (i) that 
point in time when such Major Investor no longer owns 100,000 shares of 
Series C Preferred Stock of the Company (as adjusted for subdivisions, 
conversions and stock splits), (ii) the closing of a firm commitment 
underwritten public offering pursuant to an effective registration statement 
under the Securities Act of 1933, as amended, covering the offer and sale of 
Common Stock of the Company to the public, or (iii) the occurrence of a 
merger or consolidation of the Company with or into, or the sale of all or 
substantially all of the Company's assets to another entity, unless the 
shareholders of the Company shall own at least 51% of the capital stock of 
the surviving entity immediately after such merger, consolidation or sale.

   4.2 Legends.  Each certificate representing shares of Common Stock owned 
by a Founder shall be endorsed with the following legend:

         "THE SALE OR TRANSFER OF THE SECURITIES REPRESENTED 
         BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS 
         OF A FOUNDERS' SALE AGREEMENT BY AND AMONG THE SHAREHOLDER, 
         THE CORPORATION AND CERTAIN OTHER SHAREHOLDERS OF THE 
         CORPORATION.  COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON 
         WRITTEN REQUEST OF THE SECRETARY OF THE CORPORATION."


                                       7

<PAGE>

   4.3 Legend Removal.  The legend referred to in Section 4.2 shall be 
removed upon termination of this Agreement in accordance with the provisions 
of Section 4.1 above.

   4.4 Stop Transfer Instructions.  Each Founder agrees, to ensure 
compliance with the restrictions referred to herein, that the Company may 
issue appropriate "stop transfer" certificates or instructions and that, if 
the Company transfers its own securities, it may make appropriate notations 
to the same effect in its records.

                                   SECTION 5

                                 MISCELLANEOUS

Major Investors, any provision hereof.

   5.5 Counterparts.  This Agreement may be executed in any number of 
counterparts, all of which together shall constitute one instrument, and each 
of which may be executed by less than all of the parties to this Agreement.

   5.6 Severability.  In the event that any provision of this Agreement 
becomes or is declared by a court of competent jurisdiction to be illegal,

faith, a valid, legal and enforceable substitute provision which most nearly 
effects the intent of the parties in entering into this Agreement.

     6.    INSTALLATION & ACCEPTANCE.

           (a) GENERAL. ACE*COMM and SpectraNet shall cooperate to develop 
acceptance test procedures ("ATPs") that shall provide guidelines to 
determine whether or not the Deliverables substantially perform as set forth 
in the applicable Specifications and which ATPs shall be subject to 
SpectraNet's approval. The parties acknowledge that nothing contained in the

and provide on-site installation assistance for the Deliverables that are to 
be delivered as part of Phases 1, 2 and 3 pursuant to the schedule set forth 
in the Statement of Work. For each such phase, SpectraNet shall accept or 
reject the Deliverables that are part of such phase within 30 days after 
ACE*COMM'S successful installation of such Deliverables at the last of the 
locations designated by SpectraNet on or before May 15, 1997 to have such 
Deliverables installed; provided, however, that such 30 day period shall be 
extended by up to 30 days in the event that SpectraNet reports any reasonable 
errors or defects in such Deliverables that are not remedied by ACE*COMM 
within the initial 30 day period. SpectraNet shall provide ACE*COMM with a 
reasonably detailed description of any such errors or defects and the portion 
of the Specifications at issue. ACE*COMM shall use all commercially 
reasonable efforts to correct such reported error or defect. At the end of

day testing period (as extended if applicable), the ATPs shall be executed and 
SpectraNet shall accept such Deliverables by written notice to ACE*COMM if 
(i) such Deliverables successfully completes each step of the applicable 
ATPs, and (ii) such Deliverables do not contain, in SpectraNet's reasonable 
judgment, any material and substantial non-conformances when compared to the 
applicable Specifications ("ACCEPTANCE" or "ACCEPTED"). If such standards for 
Acceptance have not been met, SpectraNet may reject such Deliverables. 
Following Acceptance of a Deliverable, any defects in such Deliverable shall 
be subject to Section 11.

          (b)  DECISION NOT TO ACCEPT. If the standards for Acceptance as set 
forth in Section 6(a) have not been met with respect to the Deliverables that 
are part of either Phase 1 on the one hand, or Phases 2 and 3 on the other 
hand, and SpectraNet has rejected such Deliverables, then SpectraNet shall 
pay ACE*COMM a maximum of 40% of the license fees and service fees listed in 
the Statement of Work payable with respect to the rejected phases. If (i) 
SpectraNet has elected to pay the license fees on a monthly payment schedule 
as provided for in the Statement of Work, and (ii) at the time of the 
rejection of the applicable phase(s), SpectraNet has paid in excess of 40% of 
the license fees and service fees for such rejected phase(s) (not including
any accrued interest that is payable or has been paid), then ACE*COMM shall 
refund to SpectraNet the amount of any license and/or service fees (together 
with any accrued and paid interest) that SpectraNet has paid in excess of 40% 
of the license fees and service fees for such rejected phase(s).

     7.  PAYMENT, INVOICES AND LATE CHARGES.  ACE*COMM shall invoice 
SpectraNet for the Deliverables pursuant to the payment schedule set forth in 
the Statement of Work. The amounts shown on such invoices shall be due within 
30 days from SpectraNet's receipt of such invoice. ACE*COMM reserves the 
right to delay its performance hereunder without prejudice if amounts are not 
paid when due. ACE*COMM retains a purchase money security interest and the 
right to assert appropriate liens with respect to all Deliverables until all 
amounts due are paid in full. Any late payment shall be subject to any costs 
of collection (including reasonable legal fees) and shall bear interest at 
the rate of one and one-half (1.5) percent per month or fraction thereof 
until paid.

     8.  TRAINING & DOCUMENTATION.  ACE*COMM shall provide training and 
technical or user documentation in support of the Deliverables to the extent 
and at the prices, if any, set forth on the Statement of Work. Any additional 
training or documentation shall be provided at ACE*COMM's then prevailing

such terms are used in this Section 9 shall include use and installation in 
connection with such networked or distributed system and access to such 
network from remote locations.

          (d)  TRANSFER OF LICENSE.  Such license shall be transferable by 
SpectraNet in object code form only pursuant to Section 21 upon the 
transferee's written agreement to be bound by the terms and conditions 
contained in this Agreement applicable to the license hereunder. Subject to 
the release of the Escrow Materials (as defined below) pursuant to

and update substantial amounts of additional data and information 
(collectively, "SPECTRANET DATA") using the Software.  SpectraNet shall retain 
all right, title and interest in and to SpectraNet Data.  Nothing contained in 
this Agreement shall be deemed or construed to limit or prevent SpectraNet from 
using the Software (or any other process, program or device) to copy, modify, 
sell, license, distribute, transmit, reformat, reconfigure or manipulate 
SpectraNet Data in any way.  SpectraNet or any employee, third-party 
consultant, contractor or subcontractor or temporary employee of SpectraNet may 
at any time (including after any termination of this Agreement) access by any 
means any program, communications or computer equipment, network and/or 
database in which, or in connection with which, SpectraNet Data is then stored 
to do any of the foregoing and nothing in this Agreement shall be deemed or 
construed to require that SpectraNet use Deliverables by ACE*COMM in order to 
access any SpectraNet Data.

     10.  CONFIDENTIAL INFORMATION.

          (a)  ACKNOWLEDGMENT OF CONFIDENTIALITY. Each party hereby 
acknowledges that it may be exposed to confidential and proprietary information 
of the other party including, without limitation, any trade secrets embodied in 
the source code for Standard Software Products, the Custom Work Product, the 
Embedded Software and other technical information (including functional and 
technical specifications, designs, drawings, analysis, research, process, 
source code versions of computer programs, algorithms, methods, ideas, "know 
how" and the like), business information (sales and marketing research, 
materials, plans, accounting and financial information, personnel records and 
the like) and other information that has been clearly designated in writing as 
confidential ("Confidential Information").  Confidential Information does not 
include (i) information previously known or independently developed by the 
recipient; (ii) information in the public domain through no wrongful act of the 
recipient, or (iii) information received by the recipient from a third party 
who was free to disclose it.

          (b)  COVENANT NOT TO DISCLOSE. With respect to the other party's 
Confidential Information, the recipient hereby agrees that during the Term and 
at all times thereafter it shall not use, commercialize or disclose such 
Confidential Information to any person or entity, except to its own employees 
(and in the case of SpectraNet, to its temporary employees and to any 
contractors retained to perform data entry or related services) having a "need 
to know" (and who are themselves bound by similar nondisclosure restrictions), 
and to such other recipients as the other party may approve in a signed writing;
provided, that all such recipients shall have first executed a confidentiality 
agreement in a form acceptable to the owner of such information. Each party 
shall use at least the same degree of care in safeguarding the other party's 
Confidential Information as it uses in safeguarding its own confidential 
information. Neither

party nor any recipient may alter or remove from any software or associated 
documentation owned or provided by the other party hereunder, any proprietary, 
copyright, trademark or trade secret legend, nor may it attempt to decompile or 
reverse engineer such software.  The provisions of this Section 10 shall survive
termination of this Agreement.

          (c)  REMEDIES FOR BREACH OF CONFIDENTIALITY.  Each party acknowledges 
that the unauthorized use, commercialization or disclosure of the other party's 
Confidential Information would cause irreparable harm to such other party.  The 
parties acknowledge that remedies at law would be inadequate to redress the 
actual or threatened unauthorized use, commercialization or disclosure of such 
Confidential Information and that a party may seek temporary and permanent 
injunctive relief to enforce the foregoing restrictions.  Each party shall pay 
its own costs and expenses (including attorneys' fees) incurred in any 
proceeding arising under this Section 10.

          (d)  NORMAL USE.  Except as otherwise specifically set forth in 
Section 9, nothing in this Section 10 shall be deemed to restrict SpectraNet 
from using any of SpectraNet's Data or any Deliverable in the ordinary course 
of its business it being understood that many employees, subcontractors and 
others will use the Confidential Information in completing their duties for 
SpectraNet and that it may become necessary for SpectraNet to interface 
Confidential Information constituting software to other systems utilized by 
SpectraNet, its customers, its suppliers, and its consultants.

SpectraNet has made no changes (nor permitted any changes to be made) other 
than by or with the express approval of ACE*COMM to the Software source code. 
Any failure by SpectraNet to satisfy the foregoing conditions shall not be a 
breach of this Agreement but shall delay or suspend ACE*COMM's warranty 
response obligations set forth in Section 11(d); provided, however, that (a) 
any such delay or suspension by ACE*COMM shall not extend the applicable 
Warranty Period, and (b) ANY UNAUTHORIZED

CHANGES TO THE SOFTWARE SOURCE CODE WILL VOID THE WARRANTY PROVIDED UNDER 
THIS SUBSECTION.

          (d)  WARRANTY RESPONSE.

               (i)   GENERAL. During the Warranty Period, upon being notified 
     by SpectraNet in accordance with ACE*COMM's standard "trouble report" 
     procedures (written copies of which have been or shall be provided to 
     SpectraNet) of a Major Alarm that is covered by the warranty set forth 
     in Section 11(c), ACE*COMM shall respond by telephone to acknowledge the 
     Major Alarm within 4 business hours and, with the cooperation of 
     SpectraNet (including installation of dial-in contact via modem), shall 
     promptly commence diagnosis and error correction efforts and shall use 
     all commercially reasonable efforts to correct such Major Alarm.

               (ii)  MINOR ALARMS. Minor Alarms shall be diagnosed and 
     corrected by ACE*COMM within a reasonable time by telephone support or 
     through the issuance of periodic updates. ACE*COMM acknowledges that a 
     large accumulation of Minor Alarms may collectively be characterized and 
     treated by SpectraNet as a Major Alarm if not corrected within a 
     reasonable time. All corrections issued in response to Major Alarms and 
     Minor Alarms shall during the original Warranty Period only be warranted 
     against defects to the same extent as the original Deliverable.

               (iii) OUT OF POCKET EXPENSES. Out-of-pocket travel expenses 
     and reasonable costs of labor incurred by ACE*COMM in providing on-site 
     assistance required to correct problems not covered by warranty shall be 
     borne by SpectraNet and, in any event SpectraNet shall bear all travel 
     expense associated with problems that are covered by warranty.

          (e)  WARRANTY DISCLAIMER. EXCEPT AS SPECIFICALLY PROVIDED IN THIS 
SECTION 11, ACE*COMM HEREBY DISCLAIMS WITH RESPECT TO ALL DELIVERABLES 
PROVIDED HEREUNDER, ALL EXPRESS AND IMPLIED WARRANTIES, INCLUDING ANY IMPLIED 
WARRANTIES OF MERCHANTABILITY, TITLE OR FITNESS FOR A PARTICULAR PURPOSE.

          (f)  DISCLAIMER REGARDING GOVERNMENTAL LAWS AND REGULATIONS. THE 
PARTIES HEREBY AGREE THAT, TO THE EXTENT ANY DELIVERABLE HEREUNDER IS USED 
FOR THE PURPOSE OF GENERATING OUTPUT USED IN COMPLYING WITH GOVERNMENTAL LAWS 
AND REGULATIONS (INCLUDING TAX LAWS AND REGULATIONS), SPECTRANET SHALL ASSUME 
ALL RESPONSIBILITY FOR HAVING THE DELIVERABLES THOROUGHLY TESTED BY 
QUALIFIED PROFESSIONALS TO ENSURE THE OUTPUT IS ACCURATE AND COMPLETE, 
PROVIDED, HOWEVER, THAT ANY ERRORS DISCOVERED BY SPECTRANET WITH REGARD TO 
SUCH OUTPUT SHALL BE SUBJECT TO REPAIR BY ACE*COMM PURSUANT TO THIS SECTION 
11.

     12.  LIMITATION OF REMEDIES & LIABILITIES. The parties acknowledge that 
the following provisions have been negotiated by them and reflect a fair 
allocation of risk:

          (a)  REMEDIES. Except for (i) SpectraNet's Acceptance rights under 
Section 6, (ii) certain injunctive relief authorized under Sections 10, 16 
and 17 and (iii) indemnification authorized under Sections 11(b), 18, 26 and 
27, SpectraNet's sole and exclusive remedies for ACE*COMM's default hereunder 
shall be (i) to obtain the repair, replacement or correction of the defective 
Deliverable, or, if ACE*COMM reasonably determines that such remedy is not 
economically or technically feasible and (ii) to obtain in accordance with 
the specific provisions of this Agreement an equitable partial or full refund 
of amounts paid with respect to the defective Deliverable.

          (b)  LIMITATION ON ACE*COMM'S LIABILITY. EXCEPT FOR DAMAGES ARISING 
FROM BODILY INJURY CAUSED BY THE NEGLIGENCE OF ACE*COMM, DAMAGES COVERED BY 
THE INDEMNIFICATION AUTHORIZED UNDER SECTIONS 11(b), 18 AND 26, AND ANY 
INJUNCTIVE RELIEF AUTHORIZED PURSUANT TO THIS AGREEMENT, (i) ACE*COMM SHALL 
NOT BE LIABLE FOR ANY AMOUNT EXCEEDING THE PORTION OF THE TOTAL CONTRACT 
PRICE ACTUALLY PAID BY SPECTRANET, AND (ii) IN NO EVENT SHALL ACE*COMM BE 
LIABLE, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE) OR OTHERWISE, FOR 
ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFIT OR 
BUSINESS INTERRUPTION EVEN IF ACE*COMM IS NOTIFIED IN ADVANCE OF SUCH 
POSSIBILITY) ARISING OUT OF OR PERTAINING TO THE SUBJECT MATTER OF THIS 
AGREEMENT.

          (c)  LIMITATION ON SPECTRANET'S LIABILITY. EXCEPT FOR CHANGE ORDERS 
AGREED TO BY THE PARTIES UNDER SECTION 2(b), IN NO EVENT SHALL SPECTRANET BE 
LIABLE TO ACE*COMM OR TO ANY THIRD PARTY, WHETHER IN CONTRACT, TORT 
(INCLUDING NEGLIGENCE) OR OTHERWISE, FOR ANY INDIRECT, INCIDENTAL OR 
CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFIT, BUSINESS INTERRUPTION OR COST 
OF COVER EVEN IF SPECTRANET IS NOTIFIED IN ADVANCE OF SUCH POSSIBILITY) 
ARISING OUT OF ANY USE BY ACE*COMM OF ANY INFORMATION, DATA, DESIGN, ADVICE 
OR OTHER MATERIALS OBTAINED FROM SPECTRANET OR ANY FAILURE BY SPECTRANET TO 
DELIVER ANY SUCH INFORMATION, DATA, DESIGN, ADVICE OR OTHER MATERIALS.

postage prepaid to the address set forth below, or to such other address as 
the parties may from time to time give notice:

     14.  ARBITRATION. Except for certain injunctive relief authorized under 
Sections 10,11, 16 and 17, which may be sought at any time, any dispute 
between the parties arising out of or relating to this Agreement or a breach 
hereof which dispute is not resolved within 10 days after receipt of notice 
by the allegedly breaching party, such dispute shall immediately be referred 
for resolution jointly by senior executives of the parties who are authorized 
to negotiate a resolution to such dispute. If such individuals are unable to 
agree upon a resolution within 20 days after referral of such dispute to them 
(such 20 day period together with the preceding 10 day period being referred 
to as the "RESOLUTION PERIOD;" provided, however that the Resolution Period 
shall in no event be less than 30 days), then either party may, upon notice 
to the other party pursuant to Section 13, refer the dispute for final, 
binding arbitration to J.A.M.S./Endispute or its successor organization for 
arbitration before a panel of three arbitrators (with each party choosing one 
arbitrator and the third arbitrator being chosen by the first two 
arbitrators) in Washington DC. Such arbitration shall be conducted under the 
administrative rules of J.A.M.S./Endispute; provided, however, that in the 
event of any conflict between such administrative rules and this Section 14, 
the provisions of this Section 14 shall govern. Each party shall bear its own 
costs and attorneys' fees with respect to such arbitration. The award of the 
arbitrators shall include a written explanation of their decision. The 
parties hereby agree that arbitration before J.A.M.S./Endispute pursuant to 
this Section 14 shall be the parties' exclusive remedy and that the 
arbitration decision and award, if any, shall be final, binding upon, and 
enforceable against, the parties, and may be confirmed by the judgment of a 
court of competent jurisdiction.

     15.  CHOICE OF LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN 
ACCORDANCE WITH THE SUBSTANTIVE LAWS OF MARYLAND.

     16.  TERMINATION. 

          (a)  If SpectraNet materially breaches this Agreement at any time 
before it has Accepted either Phase 1,2 or 3, then ACE*COMM may terminate 
this Agreement with respect to any Uncompleted Phases (as defined below) 
effective no earlier than the expiration of the applicable Resolution Period 
upon prior written notice to ACE*COMM. Upon a termination


                                      12

SYSTEM ACQUISITION AGREEMENT                                    Ser. No. 97-0183
- --------------------------------------------------------------------------------

pursuant to this Section 16(a), SpectraNet shall return or destroy all 
Deliverables theretofore delivered by ACE*COMM with respect to any Uncompleted 
Phases and SpectraNet shall pay ACE*COMM an aggregate amount for such 
Uncompleted Phase that (i) does not exceed the license and service fees for 
such Uncompleted Phase as set forth in the Statement of Work, and that (ii) 
reasonably reflects ACE*COMM's costs and expenses for performing the work 
completed on such Uncompleted Phase as of the date of termination.  ACE*COMM 
shall refund any amount already paid by SpectraNet that exceeds the amount that 
is determined to be owed to ACE*COMM under phrase (ii) of the preceding 
sentence.  An "UNCOMPLETED PHASE" shall be any of Phase 1, 2 or 3 for which 
SpectraNet has not made the final license fee and service fee payment as set 
forth in the payment schedule in the Statement of Work.  In no event shall 
ACE*COMM enjoin or otherwise prevent or seek to prevent any use by SpectraNet 
of any Deliverables that have been Accepted by SpectraNet and which use is 
otherwise authorized under this Agreement.  In the event of any such 
unauthorized use of any such Accepted Deliverable by SpectraNet, ACE*COMM shall 
be entitled to seek injunctive relief with respect to the unauthorized use, 
without posting bond or other security, and without the necessity of proving 
actual damages.

          (b)  Any notice from a party with respect to an alleged breach by the 
other party shall conform to the requirements of Section 13 and shall identify 
the contract provision at issue and describe in reasonable factual detail how 
such party believes the other party has materially violated such provision.


                                  Article IV.
                            MISCELLANEOUS PROVISIONS

     17.  SOURCE CODE ESCROW.

          (a)  ESCROW AGREEMENT.  ACE*COMM shall enter into a source code 
escrow agreement with Data Securities International, Inc., (the "ESCROW 
HOLDER") in the form attached hereto as Exhibit C pursuant to which SpectraNet 
shall be a named beneficiary (the "ESCROW AGREEMENT").  ACE*COMM shall 
continually maintain such Escrow Agreement.  SpectraNet shall be responsible 
for any fees due under the Escrow Agreement that are charged by the Escrow 
Holder with respect to the Escrow Materials (as defined below) that are being 
held for the benefit of SpectraNet.  ACE*COMM shall deposit and continually 
maintain in escrow with the Escrow Holder a copy of the most current version of 
the source code for any and all portions of the Software which have been 
Accepted and for which ACE*COMM is authorized to sublicense the source code 
(including at a minimum the Standard Software Products, the Embedded Software 
and the Custom Work Product) together with all additional relevant 
documentation required for an experienced programmer/analyst to reasonably 
understand and maintain such portion of the Product, brought up to date to the 
date of delivery of such Software (collectively the "ESCROW MATERIALS"), and 
ACE*COMM shall continue to update such Escrow Materials as the applicable 
software is modified or improved in accordance with this Agreement.

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

          (b)  RELEASE EVENTS.  The Escrow Materials shall be released to 
SpectraNet solely upon the occurrence of one or more of the following "RELEASE 
EVENTS":

                    (i)   If ACE*COMM ceases to provide or is unable to continue
          to provide its repair, support and maintenance obligations for the 
          Software under either Section 11 (during the Warranty Period) or 
          under the Maintenance Agreement.

                    (ii)  If the Escrow Agreement expires or is terminated 
          without ACE*COMM entering into a new Escrow Agreement and naming a 
          new Escrow Holder pursuant to Section 17(d).

                    (iii) If ACE*COMM fails to deposit or maintain with the 
          Escrow Holder all required Escrow Materials promptly after such Escrow
          Materials become available.

                    (iv)  Upon any other breach of this Agreement by ACE*COMM 
          that is not cured by ACE*COMM within 30 days after notice by 
          SpectraNet and which breach is determined to be a material breach of 
          this Agreement by ACE*COMM under an arbitration proceeding pursuant 
          to Section 16.

                    (v)   If ACE*COMM (a) fails to continue to do business in 
          the ordinary course, (b) voluntarily or involuntarily dissolves or 
          winds-up its affairs, (c) becomes insolvent, (d) files for 
          bankruptcy, makes a general assignment for the benefit of its 
          creditors, or fails within 30 business days to dismiss any 
          involuntary proceeding seeking the entry of an order for relief under 
          any bankruptcy or related laws or the appointment of a receiver on 
          account of the insolvency of ACE*COMM and ACE*COMM or its successor in
          interest fails to perform its obligations under this Agreement within 
          30 days after such filing or appointment.

          (c)  LICENSE.  Upon the occurrence of any Release Event, SpectraNet 
is hereby granted a license to take all actions with respect to such Escrow 
Materials reasonably necessary to continue to support, maintain and use the 
Software for the purposes authorized under this Agreement.

          (d)  REPLACEMENT OF ESCROW HOLDER.  ACE*COMM shall have the right to 
replace Escrow Holder with another qualified escrow holder pursuant to another 
escrow agreement substantially similar to the Escrow Agreement.  ACE*COMM shall 
notify SpectraNet, in writing, of the new escrow holder and shall certify in 
writing that a new copy of the Escrow Materials have been deposited with the 
new escrow holder.  ACE*COMM shall enter into such supplementary agreement(s) 
with SpectraNet and the new escrow holder as are necessary to make SpectraNet a 
named beneficiary of such new escrow agreement.  Upon such change and 
replacement, the subsequent escrow holder shall become for all purposes the 
Escrow


                                      14
<PAGE>
SYSTEM ACQUISITION AGREEMENT                                  SER. NO. 97-0183
- ------------------------------------------------------------------------------

Holder and the subsequent escrow agreement shall become the Escrow Agreement 
for all purposes.

          (e)  INJUNCTIVE RELIEF. ACE*COMM and SpectraNet each acknowledge 
that the release of the Escrow Materials to SpectraNet upon the occurrence of 
a Release Event is essential to protect the legitimate business interests of 
SpectraNet and that ACE*COMM's or Escrow Holder's failure to release such 
Escrow Materials upon the occurrence of the applicable Release Event will 
result in irreparable injury to SpectraNet, and that in such event the exact 
amount of damages is now and will be difficult to ascertain and the remedies 
at law for any such failure would not be reasonable or adequate compensation. 
Accordingly, ACE*COMM and SpectraNet agree that if ACE*COMM or Escrow Holder 
fail to release the Escrow Materials following the applicable Release Event, 
SpectraNet shall be entitled to specific performance and injunctive relief, 
without posting bond or other security, and without the necessity of proving 
actual damages.

     18.  INDEPENDENT ACE*COMM STATUS. Each party and its people are 
independent contractors in relation to the other party with respect to all 
matters arising under this Agreement. Nothing herein shall be deemed to 
establish a partnership, joint venture, association or employment 
relationship between the parties. Each party shall remain responsible for and 
shall indemnify and hold harmless the other party for the withholding and 
payment of all Federal, state and local personal income, wage, earnings, 
occupation, social security, unemployment, sickness and disability insurance 
taxes, payroll levies or employee benefit requirements (under ERISA, state 
law or otherwise) now existing or hereafter enacted and attributable to 
themselves and their respective people.

     19.  ENTIRE AGREEMENT, AMENDMENT. This document, the Statement of Work, 
the accompanying Specifications and any applicable provisions under Section 
25, which are hereby incorporated by reference, constitute the entire 
agreement between the parties and supersede all other representations, 
understandings or communications, whether written or verbal, with respect to 
the subject matter hereof. This Agreement is expressly limited to its terms 
and any different or additional provisions of any purchase order, invoice or
similar documentation or printed form are specifically rejected and shall 
have no effect. Any amendment, modification or waiver of this Agreement, or 
any part hereof, shall be binding upon the parties only if such amendment, 
modification or waiver specifically references this agreement and has been 
signed by representatives of both parties specifically authorized to execute 
such binding amendments. Waiver of any provision of this Agreement in one 
instance shall not preclude future enforcement of it in future situations.

     20.  SEVERABILITY. If any provision hereof is determined by a tribunal 
of competent jurisdiction to be illegal or unenforceable, it shall 
automatically be deemed conformed to the minimum requirements of law and, 
along with all other provisions hereof, shall thereupon be given full force 
and effect. Headings are for reference purposes only and have no substantive 
effect.

                                      15

     21.  ASSIGNMENT, SUBCONTRACTING. Upon the consent of ACE*COMM (which 
consent shall not be unreasonably withheld), SpectraNet may transfer or 
assign this Agreement, including the licenses granted hereunder, to any 
parent, subsidiary or other affiliate controlled by any of the foregoing 
(where "control" for purposes of this Section 21 means a 50% ownership 
interest); provided, however, that if such transfer or assignment by 
SpectraNet is done as part of a public offering of securities by SpectraNet, 
by an entity that directly or indirectly controls SpectraNet, or by an entity 
directly or indirectly controlled by SpectraNet, then SpectraNet shall 
provide written notice to ACE*COMM of such transfer or assignment, but 
ACE*COMM's consent to such transfer or assignment shall not be required.
ACE*COMM reserves the right to subcontract discrete portions of the Statement 
of Work with SpectraNet's consent, which shall not unreasonably be withheld. 
This Agreement is binding upon and is enforceable by the parties and their 
authorized successors and assigns. Except as otherwise provided in this 
Section 21, neither party may assign this Agreement or any of its rights or 
obligations hereunder without the written consent of the other party and any 
attempt to do so shall be void and of no legal effect. In any permitted 
transfer, assignment or subcontracting of this Agreement, the transferring, 
assigning or subcontracting party shall remain liable and responsible for all 
transferred, assigned or subcontracted rights and obligations.

     22.  FAX COUNTERPARTS. A facsimile of this Agreement and notices sent 
according to Section 13 generated in good form from a telecopier "fax" 
machine (as well as a photocopy thereof) shall be treated as "original" 
documents admissible into evidence unless a document's authenticity is 
genuinely placed in question.

     23.  FORCE MAJEURE. Excluding any of SpectraNet's payment obligations 
under this Agreement, neither party shall be liable for delays or failure to 
perform as a direct result of causes beyond its reasonable control, including 
acts of god (such as fire, storm, earthquake), electrical outages, labor 
disputes or delay or failure by others to provide proper site or 
environmental conditions, or in the performance of any co-contractor or 
subcontractors selected by the other party.

     24.  NONSOLICITATION. During the Term and for a period of one (1) year 
thereafter, each party agrees not to solicit, nor attempt to solicit, the 
services of any employee of the other party without the prior written consent 
of the other party. If this provision is violated, the violating party shall 
pay liquidated damages equal to one hundred fifty (150) percent of the 
solicited person's annual compensation; provided that upon making such 
payment, the violating party shall not be in breach of this Agreement.

     25.  SECURITY, NO CONFLICTS. Each party agrees to inform the other party 
of any information made available to it that is classified or restricted 
data, agrees to comply with the security requirements imposed by any state or 
local government, or by the United States Government, and shall return all 
such material upon request. Each party represents that its participation in 
this Agreement does not create any conflict of interest prohibited by the 
United States Government or any other domestic or foreign government and 
shall promptly notify the other party if any such conflict arises during the 
Term.

     26.  INSURANCE INDEMNITY. ACE*COMM shall maintain during the Term hereof 
reasonable insurance protection for ACE*COMM's workers and their work 
hereunder and shall to the extent of such coverage indemnify SpectraNet for 
bodily injury and physical property damage directly and solely attributable 
to the negligent or intentional acts of its employees occurring within the 
scope of their employment. SpectraNet shall maintain secure, up-to-date 
archival copies of all valuable data, software programs and the like, as well 
as adequate liability, casualty and business interruption insurance and 
appropriate disaster recovery plans.

     27.  COMPLIANCE WITH EXPORT REGULATIONS. SpectraNet has or shall obtain 
in a timely manner all necessary or appropriate licenses, permits or other 
governmental authorizations or approvals; shall indemnify and hold ACE*COMM 
harmless from, and bear all expense of, complying with all foreign or 
domestic laws, regulations or requirements pertaining to the importation, 
exportation, or use of the technology to be developed or provided herein. 
SpectraNet shall take no action, nor omit to take any required action, which 
would cause either party to violate the Foreign Corrupt Practices Act of 1977 
or the U.S. Export Administration Regulations.

     DELIVERY OF THIS LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET 
FORTH ABOVE OR TRANSMISSION OF THIS LETTER OF TRANSMITTAL VIA FACSIMILE TO A 
NUMBER OTHER THAN AS SET FORTH ABOVE WILL NOT CONSTITUTE A VALID DELIVERY.

     The instructions accompanying this Letter of Transmittal should be read 
carefully before this Letter of Transmittal is completed.

     The undersigned acknowledges receipt of the Prospectus, dated 
___________ ___, 1998 (the "Prospectus"), of FirstWorld Communications, Inc. 
(the "Company"), and this Letter of Transmittal (the "Letter of 
Transmittal"), which together with the Prospectus constitutes the Company's 
offer (the "Exchange Offer") to exchange $1,000 principal amount at maturity 
of its 13% Senior Discount Notes due 2008 (the "Exchange Notes"), which have 
been registered under the Securities Act of 1933, as amended (the "Securities 
Act"), pursuant to a Registration Statement, for each $1,000 principal amount 
at maturity of its outstanding 13% Senior Discount Notes due 2008 (the 
"Private Notes"), of which $470,000,000 principal amount at maturity is 
outstanding. The term "Expiration Date" shall mean 5:00 p.m. New York City 
time, on _________ ___, 1998, unless the Company in its reasonable 
discretion, extends the Exchange Offer, in which case the term shall mean the 
latest date and time to which the Exchange Offer is extended.  The term 
"Holder" with respect to the Exchange Offer means any person in whose name 
Private Notes are registered on the books of the Company or any other person 
who has obtained a properly completed bond power from the registered holder. 
Capitalized terms used but not defined herein shall have the meaning given to 
them in the Prospectus.

     This Letter of Transmittal is to be used by holders of Private Notes if 
(i) certificates representing Private Notes are to be physically delivered to 
the Exchange Agent herewith, (ii) tender of the Private Notes is to be made 
by book-entry transfer to the Exchange Agent's account at The Depository 
Trust Company (the "Book-Entry Transfer Facility"), pursuant to the 
procedures set forth in the section of the Prospectus entitled "The Exchange 
Offer -- Procedures for Tendering" by any financial institution that is a 
participant in the Book-Entry Transfer Facility and whose name appears on a 
security position listing as the owner of Private Notes to the extent 
provided herein or (iii) tender of the Private Notes is to be made pursuant 
to the guaranteed delivery procedures in the section of the Prospectus 
entitled "The Exchange Offer -- Guaranteed Delivery Procedures." See 
Instruction 2.  Delivery of documents to the Book-Entry Transfer Facility 
does not constitute delivery to the Exchange Agent.

<PAGE>

     Notwithstanding the foregoing, valid acceptance of the terms of the 
Exchange Offer may be effected by a participant in the Book-Entry Transfer 
Facility tendering Private Notes through the Book-Entry Transfer Facility's 
Automated Tender Offer Program ("ATOP") through the transmission of a 
computer-generated message from the Book-Entry Transfer Facility to, and 
received by, the Exchange Agent (an "Agent's Message") prior to the 
Expiration Date. Accordingly, such participant must electronically transmit 
its acceptance to the Book-Entry Transfer Facility through ATOP, and then the 
Book-Entry Transfer Facility will edit and verify the acceptance, execute a 
book-entry delivery to the Exchange Agent's account at the Book-Entry 
Transfer Facility and send an Agent's Message to the Exchange Agent for its 
acceptance.  By tendering through ATOP, participants in the Book-Entry 
Transfer Facility will expressly acknowledge receipt of the Letter of 
Transmittal and agree to be bound by its terms and the Company will be able 
to enforce such agreement against such Book-Entry Transfer Facility 
participants.

     The undersigned has completed, executed and delivered this Letter of
Transmittal to indicate the action the undersigned desires to take with respect
to the Exchange Offer.  Holders who wish to tender their Private Notes must
complete this Letter of Transmittal in its entirety.

                      NOTE: SIGNATURES MUST BE PROVIDED BELOW

                  PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY

     Ladies and Gentlemen:

          Subject to the terms and conditions of the Exchange Offer, the 
undersigned hereby tenders to the Company, the principal amount at maturity 
of Private Notes indicated above.

          Subject to and effective upon the acceptance for exchange of the 
principal amount at maturity of Private Notes tendered in accordance with 
this Letter of Transmittal, the undersigned sells, assigns and transfers to, 
or upon the order of, the Company all right, title and interest in and to the 
Private Notes tendered hereby.  The undersigned hereby irrevocably 
constitutes and appoints the Exchange Agent as its agent and attorney-in-fact 
(with full knowledge that the Exchange Agent also acts as the agent of the 
Company in connection with the Exchange Offer) with respect to the tendered 
Private Notes with full power of substitution (subject only to the right of 
withdrawal described in the Prospectus) to (i) present such Private Notes and 
all evidences of transfer and authenticity to, or transfer ownership of, such 
Private Notes on the account books maintained by the Book-Entry Transfer 
Facility to, or upon, the order of, the Company, (ii) deliver certificates 
for such Private Notes to the Company together with all accompanying 
evidences of transfer and authenticity to, or upon the order of, the Company 
and (iii) present such Private Notes for transfer on the books of the Company 
and receive all benefits and otherwise exercise all rights of beneficial 
ownership of such Private Notes, all in accordance with the terms of the 
Exchange Offer.

         The undersigned hereby represents and warrants that the undersigned 
has full power and authority to tender, sell, assign and transfer the Private 
Notes tendered hereby and that the Company will acquire good, valid and 
unencumbered title thereto, free and clear of all liens, restrictions, 
charges and encumbrances and not subject to any adverse claims, when the same 
are acquired by the Company.  The undersigned hereby further represents that 
any Exchange Notes acquired in exchange for Private Notes tendered hereby 
will have been acquired in the ordinary course of business of the person 
receiving such Exchange Notes, whether or not such person is the undersigned, 
that neither the undersigned nor any other such person has any arrangement or 
understanding with any person to participate in the distribution of such 
Exchange Notes and that neither the undersigned nor any such other person is 
an "affiliate," as defined in Rule 405 under the Securities Act, of the 
Company. In addition, the undersigned and any such person acknowledge that 
(a) any person participating in the Exchange Offer for the purpose of 
distributing the Exchange Notes must, in the absence of an exemption 
therefrom, comply with the registration and prospectus delivery requirements 
of the Securities Act in connection with a secondary resale of the Exchange 
Notes and cannot rely on the position of the staff of the Securities and 
Exchange Commission enunciated in no-action letters and (b) failure to comply 
with such requirements in such instance could result in the undersigned or 
such person incurring liability under the Securities Act for which the 
undersigned or such person is not indemnified by the Company. The undersigned 
will, upon request, execute and deliver any additional documents deemed by 
the Exchange Agent or the Company to be necessary or desirable to complete 
the assignment, transfer and purchase of the Private Notes tendered hereby.  
If the undersigned is not a broker-dealer, the undersigned represents that 
that it is not engaged in and does not intend to engage in, a distribution of 
Exchange Notes.  If the undersigned is a broker-dealer that will receive 
Exchange Notes for its own account in exchange for Private Notes that were 
acquired as a result of market-making activities or other trading activities, 
it acknowledges that it will deliver a Prospectus in connection with any 
resale of such Exchange Notes, however, by so acknowledging and by delivering 
a Prospectus, the undersigned will not be deemed to admit that it is an 
"underwriter" within the meaning of the Securities Act. Unless otherwise 
notified in accordance with the instructions set forth herein in Box 4 under 
"Broker-Dealer Status," the Company will assume that the undersigned is not a 
Participating Broker-Dealer.

         For purposes of the Exchange Offer, the Company shall be deemed to 
have accepted validly tendered Private Notes when, as and if the Company has 
given notice thereof to the Exchange Agent (such notice if given orally, to 
be confirmed in writing).

         If any Private Notes tendered herewith are not accepted for exchange 
pursuant to the Exchange Offer for any reason, certificates for any such 
unaccepted Private Notes will be returned, without expense, 

                                       4

to the undersigned at the address shown below or to a different address as 
may be indicated in Box 3 under "Special Delivery Instructions" as promptly 
as practicable after the Expiration Date.

         All authority conferred or agreed to be conferred by this Letter of 
Transmittal shall survive the death, incapacity or dissolution of the 
undersigned, and every obligation of the undersigned under this Letter of 
Transmittal shall be binding upon the undersigned's heirs, personal 
representatives, successors and assigns.

         The undersigned understands that tenders of Private Notes pursuant 
to the procedures described under the caption "The Exchange Offer -- 
Procedures For Tendering" in the Prospectus and in the instructions hereto 
will constitute a binding agreement between the undersigned and the Company 
upon the terms and subject to the conditions of the Exchange Offer, subject

under the caption "The Exchange Offer -- Withdrawal of Tenders."

the "Special Registration Instructions" and "Special Delivery Instructions" 
to transfer any Private Notes from the name of the registered holder(s) 
thereof if the Company does not accept for exchange any of the Private Notes 
so tendered.

         Holders who wish to tender their Private Notes and (i) whose Private

well as a properly completed and duly executed copy of this Letter of 
Transmittal (or, in the case of a book-entry transfer, an Agent's Message), a

an obligation to notify any tendering holder of the Company's acceptance of 
tendered Private Notes prior to the completion of the Exchange Offer.

     2.   GUARANTEED DELIVERY PROCEDURES.  Holders who wish to tender their 
Private Notes but whose Private Notes are not immediately available and who

procedures for book-entry transfer prior to the Expiration Date), the Letter 
of Transmittal and any other documents required by the Letter of Transmittal 
to the Exchange Agent prior to the Expiration Date must tender their Private 
Notes according to the guaranteed delivery procedures set forth below.  
Pursuant to such procedures:

          (i)       such tender must be made by or through a firm which is a

          (ii)      prior to the Expiration Date, the Exchange Agent must 
have received from the holder and the Eligible Institution a properly 
completed and duly executed Notice of Guaranteed Delivery (by facsimile

Letter of Transmittal form properly completed and executed by a holder who 
attempted to use the guaranteed delivery procedure.

tender such Private Notes in the Exchange Offer.  Any beneficial owner of

holder.

     4.   PARTIAL TENDERS.   Tenders of Private Notes will be accepted only 
in integral multiples of $1,000 in principal amount at maturity.  If less 
than the entire principal amount at maturity of Private Notes is tendered,

joint owners, all such owners must sign this Letter of Transmittal.  If any 
tendered Private Notes are held in different names on several Private Notes,

tendered herewith and the Exchange Notes (and any Private Notes not tendered 
or not accepted) are to be issued to such registered holder(s) and neither 
the "Special Registration Instructions" (Box 2) nor the "Special Delivery 
Instructions" (Box 3) has been completed.  In all other cases, all signatures 
on this Letter of Transmittal must be guaranteed by an Eligible Institution.

     6.   SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS.   Tendering holders 
should indicate, in the applicable box, the name and address in which the 
Exchange Notes and/or substitute Private Notes for any principal amount at 
maturity not tendered or not accepted for exchange are to be sent, if 
different from the name and address or account of the person signing this 
Letter of Transmittal.  In the case of issuance in a different name, the 
employer identification number or social security umber of the person named 
must also be indicated and the tendering holders should complete the 
applicable box.

     If no such instructions are given, the Exchange Notes (and any Private 
Notes not tendered or not accepted) will be issued in the name of and sent to 
the registered holder of the Private Notes.

     7.   TRANSFER TAXES.   The Company will pay all transfer taxes, if any, 
applicable to the sale and transfer of Private Notes to it or its order 
pursuant to the Exchange Offer.  If, however, a transfer tax is imposed for 
any reason other than the transfer and sale of Private Notes to the Company 
or its order 

                                       8
<PAGE>

pursuant to the Exchange Offer, then the amount of any such transfer taxes 
(whether imposed on the registered holder or on any other person) will be 
payable by the tendering holder.  If satisfactory evidence of payment of such 
taxes or exemption from taxes therefrom is not submitted with this Letter of 
Transmittal, the amount of transfer taxes will be billed directly to such 
tendering holder.

     Except as provided in this Instruction 7, it will not be necessary for 
transfer tax stamps to be affixed to the Private Notes listed in this Letter 
of Transmittal.

     8.   TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a 
holder of any Private Notes which are accepted for exchange must provide the 
Company (as payor) with its correct taxpayer identification number ("TIN"), 
which, in the case of a holder who is an individual, is his or her social 
security number.  If the Company is not provided with the correct TIN, the 
Holder may be subject to a $50 penalty imposed by the Internal Revenue 
Service. (If withholding results in an over-payment of taxes, a refund may be 
obtained.) Certain holders (including, among others, all corporations and 
certain foreign individuals) are not subject to these backup withholding and 
reporting requirements. See the enclosed "Guidelines for Certification of 
Taxpayer Identification Number on Substitute Form W-9" for additional 
instructions.

     To prevent backup withholding, each tendering holder must provide such 
holder's correct TIN by completing the Substitute Form W-9 set forth herein, 
certifying that the TIN provided is correct (or that such holder is awaiting 
a TIN), and that (i) the holder has not been notified by the Internal Revenue 
Service that such holder is subject to backup withholding as a result of 
failure to report interest or dividends or (ii) the Internal Revenue Service 
has notified the holder that such holder is no longer subject to backup 
withholding. If the Private Notes are registered in more than one name or are 
not in the name of the actual owner, see the enclosed "Guidelines for 
Certification of Taxpayer Identification Number on Substitute Form W-9" for 
information on which TIN to report.

     The Company reserves the right in its sole discretion to take whatever 
steps are necessary to comply with the Company's obligation regarding backup 
withholding.

     9.   VALIDITY OF TENDERS.  All questions as to the validity, form, 
eligibility (including time of receipt), and acceptance of tendered Private 
Notes will be determined by the Company, in its sole discretion, which 
determination will be final and binding.  The Company reserves the right to 
reject any and all Private Notes not validly tendered or any Private Notes, 
the Company's acceptance of which would, in the opinion of the Company or its 
counsel, be unlawful.  The Company also reserves the right to waive any 
conditions of the Exchange Offer or defects or irregularities in tenders of 
Private Notes as to any ineligibility of any holder who seeks to tender 
Private Notes in the Exchange Offer.  The interpretation of the terms and 
conditions of the Exchange Offer (including this Letter of Transmittal and 
the instructions hereto) by the Company shall be final and binding on all 
parties.  Unless waived, any defects or irregularities in connection with 
tenders of Private Notes must be cured within such time as the Company shall 
determine.  The Company will use reasonable efforts to give notification of 
defects or irregularities with respect to tenders of Private Notes, but shall 
not incur any liability for failure to give such notification.

     10.  WAIVER OF CONDITIONS.  The Company reserves the absolute right to 
amend, waive or modify specified conditions in the Exchange Offer in the case 
of any tendered Private Notes.

     11.  NO CONDITIONAL TENDERS.  No alternative, conditional, irregular or 
contingent tender of Private Notes will be accepted.

     12.  MUTILATED, LOST, STOLEN OR DESTROYED PRIVATE NOTES.  Any tendering 
holder whose Private Notes have been mutilated, lost, stolen or destroyed 
should promptly contact the Exchange Agent at the address indicated above for 
further instruction.

     13.  REQUESTS FOR ASSISTANCE AND ADDITIONAL COPIES. Requests for 
information and for additional copies of the Prospectus may be directed to 
the Exchange Agent at the address set forth on the first page of this Letter 
of Transmittal.  Holders may also contact their broker, dealer, commercial 
bank, trust company or other nominee for assistance concerning the Exchange 
Offer.

<PAGE>

     14.  ACCEPTANCE OF TENDERED PRIVATE NOTES AND ISSUANCE OF EXCHANGE 
NOTES; RETURN OF PRIVATE NOTES.  Subject to the terms and conditions of the 
Exchange Offer, the Company will accept for exchange all validly tendered 
Private Notes as soon as practicable after the Expiration Date and will issue 
Exchange Notes therefor as soon as practicable thereafter.  For purposes of 
the Exchange Offer, the Company shall be deemed to have accepted tendered 
Private Notes when, as and if the Company has given notice thereof to the 
Exchange Agent (such notice if given orally, to be confirmed in writing).  If 
any tendered Private Notes are not exchanged pursuant to the Exchange Offer 
for any reason, such unexchanged Private Notes will be returned, without 
expense, to the undersigned at the address shown above or at a different 
address as may be indicated under "Special Delivery Instructions."

     15.  WITHDRAWAL.  Tenders may be withdrawn only pursuant to the limited 
withdrawal rights set forth in the Prospectus under the caption "The Exchange 
Offer -- Withdrawal of Tenders."
