This prospectus includes forward-looking statements which involve risks and

                            Pac-West Telecomm, Inc.

Our Company

   Pac-West is a rapidly growing provider of integrated communications services
in the western United States. Our customers include Internet service providers,
small and medium businesses and enhanced communications service providers, many
of which are communications-intensive users. We believe the breadth of our
product offerings and the structure of our network enable us to generate high
network utilization, substantial revenues, strong profit margins and positive
cash flow.

   We began offering long distance service in 1982 and local service in 1996 in
California, which is our primary market. As of June 30, 1999, we had over
76,000 lines in service, a 137% increase from June 30, 1998. We estimate that
over 82% of the current utilization of these lines by our customers is to carry
data traffic and that approximately 96% of our current traffic is terminated on
our network. Since 1994, we have consistently generated positive cash flows
from operations.

   To meet demand for communications services in California, we have
established a switching site in each of Los Angeles, Oakland and Stockton, and
digital connections in each of California's 11 local access and transport
areas. In California, our network enables our customers to provide their
business and residential customers with access to Internet, paging and other
data and voice services from almost any point in the state through a local
call. This allows our customers to achieve statewide coverage with lower
capital and operating expenses. According to industry sources, the California
telecommunications market generated over $27 billion in total revenues in 1997.

   We are expanding our network into Nevada with a switch in Las Vegas and
digital connections in all of Nevada's local access and transport areas. We
intend to continue our expansion into other western states, where many of our
existing customers have operations. We expect to have ten switches with
operations in ten western states by the end of 2000. As we expand our network,
we plan to leverage our existing customer relationships to provide predictable
usage rates on our network assets, rapid revenue ramp-up and continued strong
profit margins.

   Since our inception, we have used a "smart-build" network strategy, building
and owning the intelligent components of our network while leasing unbundled
loops and transport lines from other carriers. Currently, we lease all of our
transport lines, but as traffic on our network increases, we intend to purchase
rights of use in high capacity dark fiber transport lines to interconnect
certain of our markets with an owned backbone network. This will provide us
with greater flexibility in creating and managing data and voice services and
result in cost savings. We also provide our customers with collocation
services, allowing them to house their equipment in space we operate within our
switching centers.

   We are a leading supplier of Internet access and other Internet
infrastructure services with 78 Internet service providers who have a
significant existing customer base in our markets. With this large base of
Internet service providers, we believe we are ideally positioned to provide
high-speed data services, such as digital subscriber line or DSL services, to
Internet users. Recently, we signed an agreement with Covad Communications to
provide bundled high-speed services beginning in the fourth quarter of 1999 and
are considering other ways to provide our customers with an easy method of
ordering, installing and managing high-speed Internet access.

                                       1

   In addition, with our network presence and scale, we are well positioned to
serve small and medium business customers. These customers want technologically
advanced communication solutions from a single source. Our complete product
offering of system design, equipment installation and maintenance, voice, data
and long distance services, 24/7 support, subscription services with multi-year
contracts and optional upgrades to emerging state-of-the-art equipment directly
meets the needs of this under-served market. Our focus on small and medium
businesses has resulted in significant market penetration over the past year,
as we have increased our business lines in service from approximately 2,500 to
over 12,000 from June 30, 1998 to June 30, 1999. According to industry sources,
our target markets currently have approximately 1.4 million small and medium
businesses and 16.5 million business lines.

Our Strategy

   We are focused on becoming the integrated communication provider of choice
for our customers. Our strategy to meet this objective is to:

  . Capitalize on growing demand in our current markets. The demand for data
    and voice communications services in our current markets is large and
    growing rapidly. We intend to increase our market penetration and
    capitalize on this growth by adding more switches and transport lines to
    increase our capacity, adding new and innovative products to our existing
    offerings, and repackaging and repricing our offerings in response to the
    changing demands of our customers. We believe we are differentiated by
    the architecture of our network, which supports high calling volumes and
    long holding times, the ability to access our network throughout our
    market area through a local call, and the ability of service providers to
    collocate their equipment at our switch locations.

  . Leverage existing customer base through geographic expansion. We are a
    leading supplier of Internet access and Internet infrastructure services
    in California with 78 Internet service provider customers. Our customers
    include: Concentric Network Corp., EarthLink, Inc., MindSpring
    Enterprises, Inc. and Splitrock Services, Inc. We plan to leverage our
    existing customer base by entering new markets where our current
    customers have or are beginning operations to achieve predictable usage
    rates on our network assets, rapid revenue ramp-up, and continued strong
    profit margins. By year end 2000, we plan to have operations in
    California, Nevada, Washington, Arizona, Utah, Colorado, Texas, New
    Mexico, Idaho and Oregon.

  . Focus on the small and medium business market. We believe that most small
    and medium business customers are not adequately served by our
    competitors. Our offerings are well suited to these customers. In order
    to capitalize on this opportunity we have increased our sales, customer
    care and service delivery forces to 105 as of June 30, 1999, from 53 as
    of June 30, 1998. Of these resources, our direct sales force was
    increased to 44 from 21 in the same period.

  . Launch new products and services. In order to achieve our growth
    objectives, we expect to continue introducing new and innovative products
    and services. We recently added several new products to our portfolio,
    including:

    . managed modem, a packaged product that includes incoming call access
      lines, modems, routers, and authentication services. This product
      provides Internet service provider and business customers with a non-
      capital intensive means of quickly establishing a local point of
      presence or POP throughout our coverage area.

    . remote access services, including mobile or remote office, virtual
      office, distance learning and training, and telecommuting. These allow
      customers to access and interact with home or branch office
      communications and information systems from anywhere in our market
      area through a local call.

    . high-speed data services. We offer high-speed private line data
      services and digital subscriber line services to customers. We also
      intend to explore wireless and satellite technologies in order to
      develop an array of high-speed alternatives for our customers.

  . Expand through potential strategic acquisitions. We may acquire other
    competitive local exchange carriers or communications providers to grow
    our business. We believe that strategic acquisitions will provide us with
    opportunities to accelerate our market penetration, cross-sell additional
    services, diversify our customer base and improve operating
    profitability.

                      Directed Share Subscription Program

                             Summary Financial Data

   Our statements of operations data for the period from commencement (October
1, 1996) to December 31, 1996 and for the years ended December 31, 1997 and
1998, shown in the table below, are derived from our audited financial
statements. Our statements of operations data for the six month periods ended
June 30, 1998 and 1999 and our balance sheet data as of June 30, 1999 have been
derived from our unaudited financial statements which, in the opinion of
management, include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair statement of the results for the unaudited
interim periods presented. The unaudited balance sheet data as of June 30, 1999
includes the issuance on January 29, 1999 of $150 million of 13 1/2% senior
notes due 2009. The results of our operations for the six month period ended
June 30, 1999 are not necessarily indicative of the results of operations which
we expect for the full 1999 calendar year. This summary should be read in
conjunction with the section entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and our financial statements,
including related notes thereto, included elsewhere in this prospectus.

   The unaudited "As Adjusted" summary balance sheet data reflects the sale of
the 11,400,000 shares of common stock offered by us in this offering at the
initial public offering price of $10.00 per share, after deducting the
underwriting discount and estimated offering expenses payable by us, and the
conversion of our outstanding convertible redeemable preferred stock. The
unaudited pro forma share and per share data give effect to the conversion of
our outstanding convertible redeemable preferred stock into 4,864,947 shares of
common stock, based on the preference amount as of June 30, 1999 and a
conversion price of $10.00 per share.

   On October 1, 1996, we began operations when our predecessor company
transferred its telephone and answering service divisions to us. As a result,
you have limited comparable historical financial information upon which to base
your evaluation of our past performance and the value of investing in our
common stock.

   Except as discussed below, we recognize revenues for telecommunications
services when service is provided. Such revenues include reciprocal
compensation due under our new interconnection agreement with Pacific Bell.
Reciprocal compensation due under our previous interconnection agreements with
Pacific Bell and GTE is recognized as revenue only to the extent received in
cash. Pacific Bell and GTE have each refused to pay us the portion of
reciprocal compensation due under the prior agreements which they estimate is
the result of inbound calls terminating to Internet service providers. Pacific
Bell and GTE argue that such calls are not local within the meaning of their
interconnection agreements and therefore assert that no reciprocal compensation
is due. See Note 5 to the audited financial statements, "Risk Factors--We may
not be entitled to receive reciprocal compensation for calls to Internet
service providers" and "Business--Regulatory Proceedings--Interconnection
Agreements."

   Adjusted EBITDA as used in this prospectus represents earnings before
interest, net; income taxes; depreciation and amortization; further adjusted
for the costs of merger and recapitalization; transaction bonuses and
consultant's costs; and extraordinary item. Included in other (income) expense,
net, is interest income of $5,000, $90,000, $327,000, $128,000 and $1,185,000
for the period from commencement on October 1, 1996 to December 31, 1996, for
the years ended December 31, 1997 and 1998, and for the six month periods ended
June 30, 1998 and 1999, respectively. Although EBITDA is not a measure of
financial performance under generally accepted accounting principles, we
believe it is a common measure used by analysts and investors in comparing a
company's results with those of similar companies as well as to evaluate the
capacity of a company to service its obligations.

                              Recent Developments
                                  (unaudited)

   Revenues for the third quarter of 1999, including a cash payment of $20.0
million from Pacific Bell in settlement of claims for unpaid reciprocal
compensation from prior periods, were $37.0 million, up 134% from the second
quarter of 1999 ($17.0 million or an 8% increase excluding the settlement
payment). On a year-over-year basis, third quarter 1999 revenues were up 289%
as compared to third quarter 1998 revenues of $9.5 million (a 79% increase
excluding the settlement payment). For the third quarter 1999, excluding the
settlement payment, gross margin (revenues less direct operating costs as a
percentage of revenues) was 66% and includes the effect of a significant price
reduction as a result of lower reciprocal compensation rates per minute of use
in the new two year Pacific Bell interconnection agreement. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Factors Affecting Operations."

   EBITDA for the third quarter of 1999 was $25.8 million, a 337% increase from
second quarter EBITDA of $5.9 million ($5.8 million or a 2% decrease excluding
the settlement payment). On a year-over-year basis, third quarter 1999 EBITDA
was up 790% from third quarter 1998 EBITDA of $2.9 million (a 100% increase
excluding the settlement payment).

   Net income for the third quarter of 1999 was $10.0 million (a loss of $0.5
million excluding the settlement payment), compared to net income of $0.2
million for the second quarter of 1999.

   As of September 30, 1999, Pac-West had cash and cash equivalents and
restricted cash totaling $69.0 million and total debt of $150.1 million.

   As of September 30, 1999, Pac-West had a total of 88,009 lines in service
versus 76,263 lines in service at the end of the second quarter of 1999, an
increase of 15%. In addition, on a year-over-year basis (third quarter 1999
versus third quarter 1998), lines in service increased 150%.

   Billed minutes of use increased 14% to 4.0 billion for the third quarter,
compared to the second quarter of 1999. On a year-over-year basis, billed
minutes of use increased from 2.0 billion to 4.0 billion, a 100% increase.
Total personnel increased by 29 in the quarter to 216 at September 30, 1999.

   Subsequent to September 30, 1999, GTE paid, and Pac-West recorded as
revenue, $6,308,000 of reciprocal compensation that GTE had previously
withheld. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Factors Affecting Operations." GTE has not waived its
rights to appeal, contest or seek subsequent reimbursements of amounts paid by
it as reciprocal compensation.

                                  RISK FACTORS

   You should carefully consider the risks described below before making an
investment decision. The risks and uncertainties described below are not the
only ones facing our company. Additional risks and uncertainties not presently
known to us or that we currently consider immaterial may also impair our
operations. If any of the following risks actually occur, our business,
financial condition or results of operations could be materially adversely
affected. In this case, the trading price of the common stock could decline,
and you may lose all or part of your investment.

Failure to continue our expansion would adversely affect our financial
condition.

   Our failure to expand our business in order to satisfy the growing needs of
our customers, to achieve economies of scale and to benefit from the
infrastructure we have established would adversely affect our business
prospects, financial condition and results of operations. This could result
from our inability to:

  . assess potential markets;

  . obtain required governmental authorizations, franchises, and permits;

  . implement interconnection and collocation arrangements with incumbent
    local exchange carriers;

  . lease adequate transmission capacity from inter-exchange carriers,
    incumbent local exchange carriers and competitive local exchange
    carriers;

  . purchase and install switches in additional markets; and

  . develop a sufficient customer base.

We may not be able to manage our growth, which could adversely affect our
business.

   Future expansion will place significant additional strains on our personnel,
financial and other resources. The failure to efficiently manage our growth
could adversely affect the quality of our services, our business and our
financial condition. Our ability to manage our growth will be particularly
dependent on our ability to develop and retain an effective sales force and
qualified technical personnel. The competition for qualified managers and
technical personnel in the telecommunications industry is intense, and we may
not be able to hire and retain sufficient qualified personnel. In addition, we
may not be able to maintain the quality of our operations, to control our
costs, to maintain compliance with all applicable regulations, and to expand
our internal management, technical, information and accounting systems in order
to support our desired growth.

We may not be able to comply in a cost-effective manner with current or future
regulations.

   Our provision of telecommunications services is heavily regulated at the
federal, state, and local levels. Compliance with these regulations imposes
substantial costs on us and restricts our ability to conduct our business. For
example, in each state in which we desire to offer our services, we must obtain
prior authorization from the appropriate state authorities. If we experience
delays in obtaining required approvals or fail to comply with regulatory
requirements, our business and our financial condition could be adversely
affected. In addition, regulatory requirements may change with little notice,
which would adversely affect our business prospects, financial condition and
results of operations.

A failure to establish interconnection agreements on favorable terms would
adversely affect our business.

   We must interconnect with incumbent local exchange carriers in order to
service our customers. The Telecommunications Act of 1996 mandates that
incumbent local exchange carriers interconnect with companies like ours to
provide us with individual network services components, such as origination,
termination and other services. However, it does not assure the time frame in
which those services will be offered to us or assure that we will be able to
purchase those services at rates and on terms and conditions that allow us to
remain competitive and profitable. If we have difficulties obtaining high
quality, reliable and reasonably priced services

                                       8
<PAGE>

from the incumbent local exchange carriers, our services will be less
attractive to customers and our business will be adversely affected. Our
primary interconnection agreements are with Pacific Bell and GTE. Our
interconnection agreement with GTE has expired but will remain in force until a
replacement agreement is finalized. In addition, we will need new
interconnection agreements in each new market we enter. We cannot be certain
that we will be able to enter into replacement or new interconnection
agreements on favorable terms. Based on current market conditions, we expect
that the per minute reciprocal compensation rates under these agreements will
decline from historic rates. See "Business--Regulatory Proceedings--
Interconnection Agreements."

We may not be entitled to receive reciprocal compensation for calls to Internet
service providers.

   Two incumbent local exchange carriers with which we have interconnection
agreements, Pacific Bell and GTE, refused to pay that portion of compensation
due under their prior agreements that they estimated was the result of inbound
calls terminating to Internet service providers. The total reciprocal
compensation withheld by these incumbent local exchange carriers and not
included in revenues was $3.8 million, $32.6 million and $28.4 million for the
years ended December 31, 1997 and 1998 and for the six month period ended June
30, 1999, respectively. On June 24, 1999, the California Public Utilities
Commission determined that reciprocal compensation would be payable for
Internet service provider calls under our new interconnection agreement with
Pacific Bell, which became effective on June 29, 1999. Pacific Bell requested a
rehearing of this decision, although Pacific Bell paid the full amount of our
billings for calls since the effective date of the new agreement. On October 6,
1999, Pacific Bell filed an appeal in federal district court in San Francisco
with respect to the California Public Utilities Commission decision. This
decision does not address reciprocal compensation under the prior agreement. On
September 9, 1999, Pac-West entered into a settlement agreement with Pacific
Bell regarding our claims for unpaid reciprocal compensation under our prior
interconnection agreement. Under the terms of the settlement agreement, Pacific
Bell agreed to pay $20.0 million to Pac-West and $20.0 million to certain
stockholders of Pac-West as of the date of the recapitalization in settlement
of those claims. As a result of these payments, the terms of our September 1998
recapitalization requiring additional distributions to certain of our
shareholders have been satisfied. As of September 30, 1999, the total amount of
reciprocal compensation, including late fees, which remains withheld by
incumbent local exchange carriers is approximately $7.2 million. On August 25,
1999, we, along with the commissioners of the California Public Utilities
Commission and others, were named as defendants in an action filed by GTE
California. The action challenges the legality of the California Public
Utilities Commission's decisions regarding reciprocal compensation as discussed
above. We intend to seek dismissal of the action or otherwise contest the
claims of GTE California. The obligation of GTE or other local exchange
carriers to pay this reciprocal compensation under its current agreement is
currently under review by both state and federal regulators. If it is
ultimately determined that we are not entitled to receive reciprocal
compensation for calls to Internet service providers, our business and
financial condition could be adversely affected. See "Business--Regulatory
Proceedings--Jurisdiction over and Compensation for Internet Service Provider
Traffic," "--Interconnection Agreements" and "Business--Regulation--State
Regulation."

We may not be able to compete effectively against the incumbent local exchange
carrier, which has a vested interest in making it difficult for us to service
customers.

   In each of our target markets, we will be competing principally with the
incumbent local exchange carrier serving that area. The incumbent local
exchange carriers are well-established providers of local telephone services
with most of the telephone subscribers within their respective service areas.
In addition, incumbent local exchange carriers have long-standing relationships
with regulatory authorities at the federal and state levels.

   Incumbent local exchange carriers also have increased pricing flexibility
for their private line and special access and switched access services. The FCC
has recently adopted an order that gives these carriers additional pricing
flexibility and further deregulates competitive access services, as opposed to
local exchange services, either automatically or after certain competitive
levels are reached. This order allows the incumbent local exchange carriers to
offer discounts to large customers, engage in aggressive volume and term
discount pricing practices for their customers, and/or charge competitors
increased fees for interconnection to their networks.

   We may not be able to overcome these advantages and compete successfully
with the incumbent local exchange carriers.

                                       9
<PAGE>

We may not be able to compete effectively in providing local exchange service.

   We face competition from long distance carriers, such as AT&T, MCI WorldCom
and Sprint, seeking to enter, reenter or expand entry into the local exchange
marketplace. In addition, we face competition from other competitive local
exchange carriers, resellers, cable television companies, electric utilities,
microwave carriers, wireless telephone system operators and private networks
built by large end users. This places downward pressure on prices, which may
make it difficult for us to provide these services profitably, and we may not
be able to compete effectively with these companies.

We may not be able to compete effectively in providing long distance service.

   We face intense competition from long distance carriers in the provision of
long distance services, which places downward pressure on prices for long
distance service and may make it difficult for us to provide these services
profitably. Although the long distance market is dominated by three major
competitors, AT&T, MCI WorldCom and Sprint, hundreds of other companies also
compete in the long distance marketplace. We may not be able to effectively
compete with these industry participants.

We may not be able to compete effectively with the Bell operating companies if
they are permitted to enter the long distance service market.

   Federal law currently prohibits regional Bell operating companies, including
Pacific Bell and Nevada Bell, from engaging in certain types of long distance
telephone service. However, this restriction may be removed by the FCC if the
regional Bell operating companies meet certain specified conditions and the FCC
determines that it is in the public interest. If the regional Bell operating
companies obtain permission to provide these services, or if they are able to
enter into teaming agreements with others to circumvent these restrictions, our
business could be adversely affected. It would remove the major incentive
regional Bell operating companies have to cooperate with companies like ours to
foster competition within their service areas, and it would permit them to
offer both long distance and local exchange services, a competitive advantage
which companies such as Pac-West currently are able to offer in those regions.
See "Business--Regulation."

Our competition may have superior resources, placing us at a cost and price
disadvantage.

   Many of our current and potential competitors have financial, personnel and
other resources, including brand name recognition, substantially greater than
those of Pac-West. As a result, some of our competitors can raise capital at a
lower cost than we can. Also, our competitors' greater name recognition may
provide them with a competitive advantage in marketing their services. In
addition, our competitors' costs advantages give them the ability to reduce
their prices for an extended period of time if they so choose. We may not be
able to compete effectively with these companies.

We may not be able to obtain or retain our key Internet service provider
customers, which account for a significant portion of our revenues.

   For the three month period ended June 30, 1999, ten of our fifteen largest
customers in terms of revenues were Internet service providers. As a result, a
significant reduction in usage by one or more of our key Internet service
provider customers or a general decrease in Internet service provider traffic
could result in a material decrease in our revenues for a given period. We
believe that our success in the foreseeable future will depend in large part on
our ability to develop and maintain a large Internet service provider customer
base. The competition for Internet service provider customers in the
telecommunications industry is intense, and we expect it will continue to
increase. We may not be able to increase or maintain our Internet service
provider customer base.

The technologies that we use may become obsolete, which would limit our ability
to compete effectively.

   The telecommunications industry is subject to rapid and significant changes
in technology. If we do not replace or upgrade our technology and equipment
that becomes obsolete, we will not be able to compete effectively because we
will not be able to meet customer expectations.

                                       10
<PAGE>

   The development of competing technologies, such as integrated services
digital network lines, cable modems, T-1 circuits and digital subscriber lines,
which provide significantly faster data transfer rates than the fastest current
dial-up modems, may give companies that provide these services a competitive
advantage over Pac-West. Further, if we attempt to incorporate new technologies
or products into our systems, those new technologies and products may not be
compatible with our existing technologies and services. We may not be able to
obtain timely access to new technology on satisfactory terms or incorporate new
technology into our systems in a cost effective manner or at all.

The loss of key executive officers could negatively impact our business
prospects.

   We believe that a critical component of our success will be the retention of
our key executive officers. Mr. Wallace W. Griffin, our Chief Executive
Officer, has significant expertise in the telecommunications industry and has
been instrumental in establishing and executing our business plan and strategy.
Mr. John K. La Rue, our Executive Vice President--Technology and Network
Operations and founder, and Mr. Jason R. Mills, our Vice President--Network
Operations, have a unique understanding of our network and have been
instrumental in its development. The loss of the services of one or more of
these individuals or our other executive officers, including Mr. Richard E.
Bryson, Mr. Brian K. Johnson and Mr. Dennis V. Meyer, could adversely affect
our business prospects, financial condition and results of operations.

Our inability to predict our need for resold long distance services could
subject us to various charges or penalties.

   We offer long distance services to our customers as part of our strategy to
provide one-stop integrated services. We rely on long distance carriers to
provide transmission and termination services for some of our long distance
traffic through resale arrangements. These arrangements typically provide for
the resale of long distance services on a per-minute basis and may contain
minimum volume commitments. These agreements are based on estimates of future
supply and demand for transmission capacity based on calling patterns and
traffic levels of our future customers. If we do not accurately predict our
long distance service needs, we may have to pay underutilization charges or
seek additional capacity through more expensive alternative means.

Our inability to obtain sufficient leased transport capacity could seriously
limit our operations.

   We currently lease transport capacity from various third-party carriers to
connect our switches to the incumbent local exchange carriers. If we cannot
lease sufficient transport capacity, our operations could be limited or we
could be forced to make additional unexpected up-front capital expenditures to
install our own transport capacity. This could adversely affect our business
prospects, financial condition and results of operations. See "Business--
Network."

A system failure could delay or interrupt our services.

   Our operations are dependant upon our ability to support our highly complex
network infrastructure. Many of our customers are particularly dependent on an
uninterrupted supply of services. Any damage or failure that causes
interruptions in our operations could result in the loss of these customers and
could have a material adverse effect on our business and our financial
condition. Because of the nature of the services we supply and the complexity
of our network, it is not feasible to maintain backup systems, and the
occurrence of a natural disaster, operational disruption or other unanticipated
problem could cause interruptions in the services we provide. Additionally, the
failure of a major supplier to provide the communications capacity we require,
or of a major customer to continue buying our goods and services, as a result
of a natural disaster, operational disruption or any other reason, could cause
interruptions in the service we provide and adversely affect our business
prospects, financial condition and results of operations.

We may face additional costs or a system failure due to Year 2000 issues.

   The Year 2000 computer problem refers to the potential for system and
processing failures of date-related data as a result of computer-controlled
systems using two digits rather than four to define the applicable year. As a
result, many companies' software and computer systems may need to be upgraded
or replaced in order to

                                       11
<PAGE>

comply with Year 2000 requirements. Our long distance billing system and our
accounting system are not yet Year 2000 compliant. We are replacing our billing
system to accommodate future anticipated growth with a new Year 2000 compliant
system. The manufacturer of the noncompliant accounting system has provided
software that is represented to be Year 2000 compliant. The failure to
implement these systems on a timely basis could result in erroneous billings as
a result of Year 2000 issues or the inability to correctly process data, such
as changes in applicable taxes. Our expansion into new states could be delayed
or limited as a result of capacity limitations and new product or service
introductions may be delayed. Any of these events could have a material adverse
affect on our business prospects, financial condition and results of
operations.

   Many of our customers and suppliers, particularly the incumbent local
exchange carriers and long distance carriers, could be impacted by the Year
2000 issue, which in turn could affect us. We utilize third-party equipment and
software and interact with incumbent local exchange carriers, major suppliers
and major customers that each have equipment and software that may not be Year
2000 compliant. Failure of such third-party or incumbent local exchange carrier
equipment or software to operate properly with regard to the year 2000 and
thereafter could require us to incur unanticipated expenses to remedy any
problems which could have a material adverse effect on our business prospects,
financial condition and results of operations.

   We are contacting third-party suppliers of components and our key
subcontractors used in the manufacture of our products to identify and, to the
extent possible, resolve issues relating to the Year 2000 issue. Because we
have no control over the actions of these parties, these third parties may not
remediate any or all of their Year 2000 issues. Any failure of any of these
third parties to timely resolve Year 2000 issues with either their products
sold to us, or their systems could have a material adverse effect on our
business prospects, financial condition and operating results. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Issues."

We may not be able to generate sufficient cash to service our indebtedness.

   Failure to generate cash in the future either from operations or from
additional financing will adversely affect our ability to make payments on and
to refinance our indebtedness and to fund capital expenditures and marketing
efforts. Our ability to generate cash from operations will be particularly
dependent on our ability to expand our business and manage our growth, provide
competitive services, comply with applicable governmental regulations and
negotiate favorable agreements. In addition, we may need to refinance all or a
portion of our indebtedness on or before maturity. We may not be able to
refinance this indebtedness on commercially reasonable terms or at all.

Our substantial indebtedness could adversely affect our business operations.

   We have a substantial amount of indebtedness and are highly leveraged. On an
unaudited basis, as of June 30, 1999, our long-term debt totaled $150,062,000,
and we had a stockholders' deficit of $75,634,000. We may also incur additional
indebtedness in the future to expand and develop our current business and
services and enter new markets. Our substantial indebtedness could:

  . increase our vulnerability to general adverse economic and industry
    conditions;

  . limit our ability to fund future working capital, capital expenditures,
    marketing costs and other general corporate requirements;

  . require us to dedicate a substantial portion of our cash flows from
    operations to payments on our indebtedness, thereby reducing the
    availability of our cash flows to fund working capital, capital
    expenditures, marketing efforts and other general corporate purposes;

  . limit our flexibility in planning for or reacting to changes in our
    business and the industry in which we operate;

  . place us at a competitive disadvantage compared to our less leveraged
    competitors; and

  . limit our ability to borrow additional funds.

                                       12
<PAGE>

We may not have sufficient funds available to expand our business.

   We will need to make significant capital expenditures in order to expand and
develop our current business and to enter new markets. We expect to fund these
expenditures through existing resources, through internally generated funds,
and through equity and debt financings. If we are unable to raise sufficient
funds, we may have to delay or abandon some of our expenditures or plans for
future expansion. This would result in underutilization of our established
infrastructure and reduced profitability and may negatively affect our ability
to compete for and satisfy the demands resulting from the growth and expansion
of our customers.

The covenants in our senior credit facility and senior notes indenture could
adversely affect the operation of our business.

   Our senior credit facility and senior notes indenture contain provisions
which limit our management's discretion by restricting our ability to:
  . incur additional debt;
  . pay dividends and make other distributions;
  . prepay subordinated debt;
  . make investments and other restricted payments;
  . enter into sale and leaseback transactions;
  . create liens;
  . sell assets; and
  . enter into certain transactions with affiliates.

   In addition, the senior credit facility requires us to meet certain
financial ratios.

   If we fail to comply with the restrictions of the senior credit facility,
senior notes indenture or any other subsequent financing agreements, a default
may occur. This default may allow the creditors to accelerate the related debt
as well as any other debt to which a cross-acceleration or cross-default
provision applies. In addition, the lenders may be able to terminate any
commitments they had made to supply us with further funds. See "Description of
Indebtedness."

Some shares in this offering may have been offered or sold in violation of the
Securities Act of 1933.

   Prior to the effectiveness of the registration statement covering the shares
of our common stock being sold in this offering, Safeguard Scientifics, the
selling shareholder in the directed share subscription program and an
underwriter with respect to the shares of our common stock offered to the
shareholders of Safeguard Scientifics, published information on its website
regarding directed share subscription programs. These materials may constitute
a prospectus that does not meet the requirements of the Securities Act of 1933.
If the publication of these materials by Safeguard Scientifics did constitute a
violation of the Securities Act of 1933, the recipients of these materials who
purchased common stock in this offering would have the right, for a period of
one year from the date of their purchase of common stock, to obtain recovery of
the consideration paid in connection with their purchase of common stock or, if
they had already sold the stock, sue us for damages resulting from their
purchase of common stock. Any liability would depend upon the loss per share
and the number of shares purchased by the recipients of such materials. These
damages could total $35.0 million, plus interest, based on the initial public
offering price of $10.00 per share, if these investors seek recovery or damages
after the entire loss of their investment. If this occurs, our business,
results of operations and financial condition would be harmed.

We are majority owned by equity investors and their interests may conflict with
your interests and which may have the effect of delaying or preventing a change
in control of our company.

   As of June 30, 1999, assuming the conversion of our outstanding convertible
redeemable preferred stock into 4,864,947 shares of common stock, based on the
preference amount as of June 30, 1999 and a conversion price of $10.00 per
share, Safeguard 98 Capital, L.P., SCP Private Equity Partners, L.P., TL
Ventures III L.P., EnerTech Capital Partners, L.P., William Blair Capital
Partners, L.L.C. and Bay Alarm Company collectively

                                       13
<PAGE>

own approximately 86.4% of our common stock. Following consummation of this
offering and assuming all 3,500,000 shares offered pursuant to the directed
share subscription program are purchased by shareholders of Safeguard
Scientifics, these investors will own 53.7% of our common stock. If the
shareholders of Safeguard Scientifics do not purchase any of the shares offered
in the directed share subscription program and Safeguard Scientifics purchases
all of the shares offered by us in the directed share subscription program,
these investors together with Safeguard Scientifics will own approximately
64.1% of our common stock after this offering. See "Directed Share Subscription
Program." Some of our directors are affiliated with these investors. Jerry L.
Johnson is an officer of Safeguard Scientifics, the parent of Safeguard
Delaware, Inc., the general partner of Safeguard 98 Capital, L.P.; David G.
Chandler is a managing director of William Blair Capital Partners; Mark J.
DeNino is managing director of the management company for TL Ventures III;
Samuel A. Plum is a general partner of SCP Private Equity Partners; and Bruce
A. Westphal is chairman of Bay Alarm Company. These investors may significantly
influence and ultimately make decisions that are adverse to your interests as
minority stockholders. These investors will be able to exercise control over
all matters requiring approval by our stockholders, including the election of
directors and the approval of significant corporate transactions. This
concentration of ownership may also have the effect of delaying or preventing a
change in control of our company, which could negatively affect our stock
price. For more information, see "Principal and Selling Shareholders."

   In addition to their Pac-West investment, some of these investors have
invested significantly in other telecommunications companies, Internet service
providers, and related businesses, and they or their affiliates may make
further similar investments in the future. Through these investments, these
investors may develop relationships with businesses which are competitive with
us. These relationships may lead to conflicts involving arrangements between
Pac-West and the investors' other holdings. These investors are under no
obligation to bring any investment or business opportunities of which they are
aware to Pac-West, even if the opportunity is directly within the scope of our
business operations. See "Certain Relationships and Related Transactions" and
"Principal and Selling Shareholders."

Our rapid growth and limited historical financial information may make it
difficult for you to completely evaluate us.

   On September 30, 1996, our predecessor transferred its telephone and
answering service divisions to us. Before that time, we did not conduct any
operations and, since that time, we have disposed of the answering service
division and have focused our business strategy on operating as a competitive
local exchange carrier. Due to significant changes in our operations since
September 30, 1996, we believe that the financial information of the
predecessor telephone and answering service divisions is not directly
comparable to our results of operations. In addition, since September 30, 1996,
we have had rapid growth and our industry has undergone substantial change. As
a result you have limited comparable historical financial information on which
to base your evaluation of us and this information may not be indicative of
future results.

Variability of quarterly operating results could result in fluctuations in the
trading price of the common stock.

   Our quarterly operating results have fluctuated, and will continue to
fluctuate, significantly from period to period depending upon such factors as
the success of our efforts to expand our customer base, changes in and the
timing of expenditures relating to the continued expansion of our network, the
level of reciprocal compensation received, the development of new services, the
success of our sales and marketing efforts, changes in pricing policies by us
and by our competitors, factors relating to our acquisition strategy and
certain other factors. As a result, it is likely that in some future quarters
our operating results will be below the expectations of investors and
securities analysts. If this happens, the trading price of the common stock
could decline.

Our stock price may fluctuate significantly following the offering and you
could lose all or part of your investment as a result.

   Prior to the offering, there has been no public market for our common stock.
Our common stock has been approved for quotation on the Nasdaq National Market.
We do not know how our common stock will trade in

                                       14
<PAGE>

the future. The initial public offering price has been determined through
negotiations between the underwriters and us. You may not be able to resell
your shares at or above the initial public offering price due to a number of
factors, including:

  . actual or anticipated fluctuations in our operating results;

  . changes in expectations as to our future financial performance or changes
    in financial estimates of securities analysts; and

  . the operating and stock price performance of other comparable companies.

   In addition, the stock market in general has experienced dramatic price and
volume fluctuations from time to time. These fluctuations may or may not be
based upon any business or operating results. Our common stock may experience
similar or even more dramatic price and volume fluctuation which may continue
indefinitely.

A decrease in a significant stockholder's holdings could result in a loss of
revenue generated by business from that stockholder.

   Prior to our recapitalization, Bay Alarm Company held approximately 78.0% of
our common stock. As a result of our recapitalization, Bay Alarm reduced its
interest in Pac-West to 21.7% of our common stock and 22.8% of our outstanding
convertible redeemable preferred stock and their interest will be reduced
further as a result of this offering. Our sales to Bay Alarm Company and its
subsidiary, InReach Internet LLC, collectively accounted for approximately
7.1%, 6.4% and 4.4% of our revenues for the years ended December 31, 1997 and
1998 and for the six month period ended June 30, 1999, respectively. The
reduction in Bay Alarm's holdings in Pac-West may make it and its affiliates
less likely to purchase goods and services from Pac-West in the future, which
could have an adverse affect on our results of operations. See "Certain
Relationships and Related Transactions" and "Principal and Selling
Shareholders."

There will be immediate and substantial dilution to new stockholders in the
offering.

   The initial public offering price is substantially higher than the net
tangible book value per share of common stock that will be applicable
immediately after the offering. The common stock you purchase in the offering
will have a post-offering pro forma net tangible book value per share of $7.68
less than the $10.00 per share price paid in the offering. See "Dilution."

The market price of our common stock could be adversely affected by sales of
substantial amounts of our common stock in the public market.

   Following the offering, we will have a large number of shares of common
stock outstanding and available for resale beginning at various points in the
future. The market price of our common stock could decline as a result of sales
of large numbers of shares of our common stock in the market following this
offering, or the perception that sales could occur. These sales might make it
more difficult for us to sell equity securities in the future at a time and at
a price that we deem appropriate. See "Shares Eligible for Future Sale."

Your stock ownership could be diluted if we need to sell additional shares of
our common stock to finance future acquisitions.

   Part of our business strategy is to accelerate our market penetration,
cross-sell additional services, diversify our customer base, and improve our
operating profitability through the acquisition of competitive local exchange
carriers or other telecommunications providers. In order to successfully
complete targeted acquisitions, it may be necessary for us to issue additional
equity securities that could dilute your stock ownership.

We will retain broad discretion in using the net proceeds to us from this
offering and may spend a substantial portion in ways with which you do not
agree.

   We will retain a significant amount of discretion over the application of
the net proceeds to us from this offering as well as over the timing of our
expenditures. Because of the number and variability of factors that

                                       15
<PAGE>

determine our use of the net proceeds to us from the offering, we may apply the
net proceeds to us from this offering in ways that vary substantially from our
current intentions. For more information, see "Use of Proceeds."

We could become subject to regulation as an investment company and restrictions
that could adversely affect our business.

   Upon the completion of this offering, a substantial portion of our assets
will be invested in interest-bearing securities, which could result in our
becoming an investment company subject to regulation under the Investment
Company Act of 1940. An investment company is defined as a company which is or
proposes to be engaged primarily in the business of investing, reinvesting or
trading in securities or that fails specified statistical tests concerning the
company's asset composition and sources of income. If we become classified as
an investment company, we would be subject to substantial restrictions on our
capital structure, management, operations, and transactions with affiliated
persons. These restrictions would adversely affect our business, financial
condition and results of operations.

Anti-takeover provisions could make a third-party acquisition of us difficult.

   Our bylaws provide that, following the closing of this offering, we will
have a classified board of directors, with each board member serving a three-
year term. The existence of a classified board could make it more difficult for
a third-party to acquire us without the approval of our board even where such
acquisition could have resulted in increased value to Pac-West shareholders.

Forward-looking statements may prove to be inaccurate.

   Some of the statements contained in this prospectus are forward-looking. The
words "believe," "expect," "intend," "anticipate," "estimate," "plan,"
"future," and other similar expressions generally identify forward-looking
statements. They include statements concerning:

  . liquidity and capital expenditures;

  . growth strategy;

  . acquisition activities;

  . regulatory matters affecting the telecommunications industry;

  . reciprocal compensation for Internet access services;

  . competitive conditions in the telecommunications industry;

  . projected growth of the telecommunications industry;

  . debt levels and ability to obtain financing and service debt;

  . general economic conditions; and

  . year 2000 issues.

   Actual results may differ materially from those suggested by the forward-
looking statements for various reasons, including those discussed in this
section.

                                USE OF PROCEEDS

   We estimate that we will receive net proceeds from the sale of our common
stock offered by this prospectus of approximately $105.7 million, or
approximately $118.4 million if the underwriters' over-allotment option is
exercised in full. These estimates include the deduction of the underwriting
discount and estimated offering expenses payable by us. We will not receive any
proceeds from the sale of the shares being offered by Safeguard Scientifics.

   We intend to use a portion of the net proceeds to us from this offering for
capital expenditures, including:

  . the purchase and installation of switches, transmission equipment and
    customer premises equipment in connection with our planned expansion;

  . the acquisition of rights of use in high-capacity dark fiber transport
    lines and related electronic equipment;

  . the enhancement of our network to provide additional value-added
    services; and

  . the improvement of our network management, billing and other back office
    systems.

   We will also use a portion of the net proceeds to us from this offering to
fund working capital requirements and other general corporate purposes.

   In addition, we may use a portion of the net proceeds to us from this
offering for possible future investments, acquisitions or strategic alliances
in businesses or assets that are related or complementary to our existing
business. We periodically evaluate investment, acquisition and strategic
alliance candidates as a key part of our growth strategy. We currently have no
commitments or agreements and are not involved in any negotiations with respect
to these transactions.

   We currently intend to allocate substantial proceeds among the foregoing
uses. The precise allocation of funds among these uses will depend on future
commercial, technological, regulatory and other developments in or affecting
our business, the competitive climate in which we operate and the emergence of
future opportunities. Because of the number and variability of factors that
determine our use of the net proceeds to us from this offering, we cannot
assure you that our application of the net proceeds will not vary substantially
from our current intentions. Pending these uses, we intend to invest the net
proceeds to us from this offering in short-term U.S. investment grade and
government securities.

                                DIVIDEND POLICY

   We have never paid any cash dividends on our common stock and do not
anticipate declaring or paying any cash dividends in the foreseeable future. We
currently intend to retain future earnings, if any, to fund the development and
growth of our business. Declaration or payment of future dividends, if any,
will be at the discretion of our board of directors after taking into account
various factors, including our financial condition, operating results, current
and anticipated cash needs and plans for expansion. In addition, our ability to
pay dividends on the common stock is restricted by the provisions of our senior
credit facility and our senior notes indenture. See "Description of
Indebtedness."

                      DIRECTED SHARE SUBSCRIPTION PROGRAM

   As part of this offering, we are offering 2,300,000 shares and Safeguard
Scientifics is offering 1,200,000 shares of our common stock in a directed
share subscription program to shareholders of Safeguard Scientifics, one of our
principal shareholders. Safeguard Scientifics is an underwriter with respect to
the shares of our common stock offered to the shareholders of Safeguard
Scientifics. Safeguard Scientifics is not an underwriter with respect to the
other shares of our common stock offered and is not included in the term
"underwriter" as used elsewhere in this prospectus.

   Safeguard Scientifics' shareholders may subscribe for one share of our
common stock for every ten shares of Safeguard Scientifics' common stock held
by them, and may not transfer the opportunity to subscribe to another person
except involuntarily by operation of law. Persons who owned at least 100 shares
of Safeguard Scientifics' common stock as of September 7, 1999 are eligible to
purchase shares directly from us or Safeguard Scientifics under the program.
Shareholders who own less than 100 shares of Safeguard Scientifics' common
stock will be ineligible to participate in the directed share subscription
program. Subscription orders will be satisfied first from the shares being sold
by us, and then from the shares offered by Safeguard Scientifics. If any of the
shares offered by us under the program are not purchased by the shareholders of
Safeguard Scientifics, Safeguard Scientifics, directly or through its wholly-
owned subsidiary Safeguard Delaware, Inc., will purchase these shares from us
at the closing of this offering. This purchase obligation may not be
transferred to anyone else and the only condition to the purchase obligation is
the consummation of the underwritten public offering. Sales under the directed
share subscription program will close on the day of the closing of the sale of
the other shares offered to the public. It is expected that sales under the
directed share subscription program will be reflected in each purchaser's book-
entry account at the Depository Trust Company, if any, as soon as practicable
after the closing of these sales. After the closing of these sales, we will
mail stock certificates to all purchasers who do not maintain book-entry
accounts at the Depository Trust Company.

   Prior to this offering, assuming the conversion of our outstanding
convertible redeemable preferred stock into 4,864,947 shares of common stock,
based upon the preference amount as of June 30, 1999 and a conversion price of
$10.00 per share, Safeguard Scientifics beneficially owned 3,622,649 shares or
approximately 16.1% of our common stock. After this offering, Safeguard
Scientifics will beneficially own 2,422,649 shares or approximately 7.2% of our
common stock, assuming that all 3,500,000 shares offered in the directed share
subscription program are purchased by shareholders of Safeguard Scientifics. If
the shareholders of Safeguard Scientifics do not purchase any of the shares
offered in the directed share subscription program and Safeguard Scientifics
purchases all of the shares offered by us in the directed share subscription
program, Safeguard Scientifics will beneficially own 5,922,649 shares or
approximately 17.5% of our common stock after this offering. The purchase price
under the program, whether paid by Safeguard Scientifics or its shareholders,
will be the same price per share as set forth on the cover page of this
prospectus. For purposes of this prospectus, when we present information that
reflects this offering, we have assumed that all shares offered under the
directed share subscription program are purchased by shareholders of Safeguard
Scientifics.

   The following table shows our unaudited cash and cash equivalents,
restricted cash and total capitalization as of June 30, 1999:

  . on an actual basis; and

  . on an as adjusted basis to reflect the sale of the 11,400,000 shares of
    common stock offered by us in this offering at the initial public
    offering price of $10.00 per share, after deducting the underwriting
    discount and estimated offering expenses payable by us, and to reflect
    the conversion of our outstanding convertible redeemable preferred stock
    into 4,864,947 shares of common stock, based on the preference amount as
    of June 30, 1999 and a conversion price of $10.00 per share.

                                    DILUTION

   Our net tangible book value (deficit) as of June 30, 1999 was $(75,634,000)
or $(4.30) per share. Net tangible book value (deficit) is total assets minus
the sum of liabilities and intangible assets. Our net tangible book value
(deficit) per share is net tangible book value (deficit) divided by the total
number of shares outstanding before the offering.

   Our unaudited pro forma net tangible book value (deficit) on June 30, 1999
was approximately $(26,985,000) or $(1.20) per share of common stock. Pro forma
net tangible book value (deficit) is total assets minus the sum of liabilities
and intangible assets. Pro forma net tangible book value (deficit) per share is
net tangible book value divided by the total number of shares outstanding
before the offering and after giving effect to the conversion of all
outstanding shares of our convertible redeemable preferred stock upon the
closing of this offering.

   After giving effect to adjustments relating to the offering, our unaudited
pro forma as adjusted net tangible book value on June 30, 1999 would have been
$78,705,000 or $2.32 per share. The adjustments made to determine pro forma as
adjusted net tangible book value per share are the following:

  . an increase in the total assets to reflect the net proceeds of the
    offering as described under "Use of Proceeds" at the initial public
    offering price of $10.00 per share; and

  . the addition of the number of shares offered by this prospectus to the
    number of common shares outstanding.

   The following illustrates the pro forma increase in net tangible book value
of $3.52 per share and the dilution (the difference between the offering price
per share and net tangible book value per share) to new investors:

   The calculations above exclude from the number of outstanding shares of
common stock:

  . any shares of common stock to be issued pursuant to the underwriters'
    over-allotment option;

  . 1,428,700 shares of common stock issuable upon the exercise of
    outstanding options with a weighted average exercise price of $1.48 per
    share as of June 30, 1999; and

  . 1,721,300 shares of common stock issuable upon the exercise of options
    reserved for grant under our stock option plans as of June 30, 1999.

   In addition, the calculations above assume the 2,300,000 shares offered by
us pursuant to the directed share subscription program are purchased by the
shareholders of Safeguard Scientifics and exclude 1,200,000 shares offered by
Safeguard Scientifics to its shareholders, for which no proceeds will be
received by us.

   If all of the options outstanding as of June 30, 1999 had been exercised at
that date, there would be additional dilution to new investors.

                            SELECTED FINANCIAL DATA

   The following table sets forth selected financial data of:

  . our predecessor's telephone and answering service divisions for the
    unaudited years ended December 31, 1994 and 1995 and for the nine month
    period ended September 30, 1996, and

  . Pac-West for the period from our commencement on October 1, 1996 to
    December 31, 1996, for the years ended December 31, 1997 and 1998 and for
    the unaudited six month periods ended June 30, 1998 and 1999.

Our selected financial data as of the dates and for the periods indicated were
derived from audited and unaudited financial statements contained elsewhere in
this prospectus and the unaudited financial statements of our predecessor's
telephone and answering service divisions for the years ended December 31, 1994
and December 31, 1995. The unaudited financial data as of June 30, 1998 and
1999 and for the six month periods ended June 30, 1998 and June 30, 1999
include all adjustments, consisting only of normal recurring adjustments, which
management considers necessary for a fair presentation of results for these
unaudited periods. The results of operations for the six month period ended
June 30, 1999 are not necessarily indicative of the results of operations that
we expect for the full 1999 calendar year. The following selected financial
information should be read in conjunction with the section entitled
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and our financial statements, including the related notes thereto,
included elsewhere in this prospectus.

   On October 1, 1996, we began operations when our predecessor company
transferred its telephone and answering service divisions to Pac-West. As a
result, this prospectus includes our audited financial statements for the
period from our commencement on October 1, 1996 to December 31, 1996, and for
the years ended December 31, 1997 and 1998. Due to the significant changes in
our operations since September 30, 1996, we believe that the financial
information of our predecessor's telephone and answering service divisions is
not directly comparable to our current results of operations. Accordingly, you
have limited comparable historical financial information upon which to base
your evaluation of our past performance and the value of investing in our
common stock.

   Except as discussed below, we recognize revenues for telecommunications
services when service is provided. Such revenues include reciprocal
compensation due under our new interconnection agreement with Pacific Bell.
Reciprocal compensation due under our previous interconnection agreements with
Pacific Bell and GTE is recognized as revenue only to the extent received in
cash. Pacific Bell and GTE have each refused to pay the portion of reciprocal
compensation due under the prior agreements which they estimate is the result
of inbound traffic terminating to Internet service providers. Pacific Bell and
GTE argue that such calls are not local within the meaning of their
interconnection agreements and therefore assert no reciprocal compensation is
due. See Note 5 to the audited financial statements, "Risk Factors--We may not
be entitled to receive reciprocal compensation for calls to Internet service
providers" and "Business--Regulatory Proceedings--Interconnection Agreements."

   Adjusted EBITDA represents earnings before interest, net; income taxes;
depreciation and amortization; further adjusted for the costs of merger and
recapitalization; transaction bonuses and consultant's costs; and extraordinary
item. Included in other (income) expense, net, is interest income of $11,000,
$20,000, $15,000, $5,000, $90,000, $327,000, $128,000 and $1,185,000 for the
predecessor telephone and answering service divisions for the years ended
December 31, 1994 and 1995, and for the nine month period ended September 30,
1996, and for Pac-West for the period from commencement on October 1, 1996 to
December 31, 1996, for the years ended December 31, 1997 and 1998, and for the
six month periods ended June 30, 1998 and 1999, respectively. Although EBITDA
is not a measure of financial performance under generally accepted accounting
principles, we believe it is a common measure used by analysts and investors in
comparing a company's results with those of similar companies as well as to
evaluate the capacity of a company to service its obligations.

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

Overview

   Pac-West is a rapidly-growing provider of integrated communications services
in the western United States. Our customers include Internet service providers,
small and medium businesses and enhanced communications service providers, many
of which are communications intensive users. Our predecessor, also known as
Pac-West Telecomm, Inc., began selling office phone systems in 1980 and
reselling long distance service to small and medium businesses and residential
customers in 1982. Beginning in 1986, our predecessor began offering paging and
telephone answering services to its customers. Effective September 30, 1996,
our predecessor transferred its telephone and answering service divisions to
us. Prior to September 30, 1996, we did not conduct any operations and, since
that time, we have disposed of the answering service division and have focused
our business strategy on operating as a provider of integrated communications
services. For the year ended December 31, 1998 and for the six month period
ended June 30, 1999, recognizing compensation from other communications
companies for completing their customers' calls only to the extent such
compensation was actually received in cash, we had net revenues of
approximately $42.2 million and $30.3 million and adjusted EBITDA of
approximately $16.1 million and $11.9 million, respectively.

Factors Affecting Operations

   Revenues. We derive our revenues from monthly recurring charges, usage
charges and initial non-recurring charges and telephone equipment sales and
service. Monthly recurring charges include the fees paid by customers for lines
in service and additional features on those lines, as well as equipment
collocation services. Usage charges consist of fees paid by end users for each
call made, fees paid by incumbent local exchange carriers as reciprocal
compensation for completion of their customers' calls through Pac-West, and
access charges paid by carriers for long distance traffic terminated by Pac-
West. Initial non-recurring charges are paid by end users, if applicable, for
the initiation of our service.

   We derive a substantial portion of our revenues from reciprocal compensation
paid by incumbent local exchange carriers with which we have interconnection
agreements. Reciprocal compensation revenues increased significantly in recent
fiscal quarters as a result of increasing inbound call volume from our Internet
service provider and other customers. For the years ended December 31, 1997 and
1998 and for the six month periods ended June 30, 1998 and 1999, recorded
reciprocal compensation accounted for approximately 37.4%, 37.1%, 36.9% and
41.8%, respectively, of our revenues. As of June 30, 1999, two incumbent local
exchange carriers with which we have interconnection agreements, Pacific Bell
and GTE, refused to pay that portion of reciprocal compensation due under their
prior agreement that they estimated was the result of inbound calls terminating
to Internet service providers. These incumbent local exchange carriers
contended that such Internet service provider calls are not local calls within
the meaning of their respective interconnection agreements and claimed that no
reciprocal compensation was therefore payable. The total reciprocal
compensation withheld by these incumbent local exchange carriers and not
included in revenues was $3.8 million for the year ended December 31, 1997,
$32.6 million for the year ended December 31, 1998 and $28.4 million for the
six month period ended June 30, 1999. On September 9, 1999, Pac-West entered
into a settlement agreement with Pacific Bell regarding our claims for unpaid
reciprocal compensation under our prior interconnection agreement. Under the
terms of the settlement agreement, Pacific Bell agreed to pay $20.0 million to
Pac-West and $20.0 million to certain stockholders of Pac-West as of the date
of the recapitalization in settlement of those claims. As a result of these
payments, the terms of our September 1998 recapitalization requiring additional
distributions to certain of our shareholders have been satisfied. As of
September 30, 1999, the total amount of reciprocal compensation, including late
fees, which remains withheld by incumbent local exchange carriers is
approximately $7.2 million.
   On June 24, 1999, the California Public Utilities Commission adopted a
decision in an arbitration proceeding between us and Pacific Bell which held
that reciprocal compensation would be payable for Internet service provider
calls under our new interconnection agreement with Pacific Bell which became
effective on June 29, 1999. Pacific Bell has paid the full amount of our
billings for calls since the effective date of the new agreement. On August 25,
1999, we, along with the commissioners of the California Public Utility
Commission

                                       23
<PAGE>

and others, were named as a defendant in an action filed by GTE California. The
action challenges the legality of the California Public Utility Commission's
decisions regarding reciprocal compensation as discussed above. We intend to
seek dismissal of the action or otherwise contest the claims of GTE California.
The obligation of GTE or other local exchange carriers to pay this reciprocal
compensation under its current agreement is currently under review by both
state and federal regulators. See "Certain Relationships and Related
Transactions."

   We expect that reciprocal compensation will continue to represent a
significant portion of our revenues in the future. We are currently negotiating
and implementing new interconnection agreements and the terms of the related
reciprocal compensation. The per minute reciprocal compensation rate we receive
from Pacific Bell under our new agreement is significantly lower than it was
under our previous agreement. Based on current market conditions, we also
expect that the per minute reciprocal compensation rate will similarly decline
from historic rates under any other future interconnection agreements. See
"Risk Factors--A failure to establish interconnection agreements on favorable
terms would adversely affect our business" and "--We may not be entitled to
receive reciprocal compensation for calls to Internet service providers."

   Operating Costs. Operating costs are comprised primarily of leased transport
charges, usage charges for long distance and intrastate calls and, to a lesser
extent, reciprocal compensation related to calls that originate with a Pac-West
customer and terminate on the network of an incumbent local exchange carrier or
other competitive local exchange carrier. Our leased transport charges are the
lease payments we incur for the transmission facilities used to connect our
customers to our switch and to connect to the incumbent local exchange carrier
and other competitive local exchange carrier networks. Our strategy of leasing
rather than building our own transport facilities results in our operating
costs being a significant component of total costs.

   Selling, General and Administrative Expenses. Our recurring selling, general
and administrative expenses include network development, administration and
maintenance costs, selling and marketing, customer service, information
technology, billing, corporate administration and personnel. We expect to incur
significant selling and marketing costs as we continue to expand our
operations, a significant amount of which will be incurred in a particular
market before the switch becomes operational and begins to generate revenue.
Consequently, selling and marketing expenses are expected to increase until
implementation of our expansion plan is substantially complete. We will incur
other costs and expenses, including the costs associated with the development
and maintenance of our networks, administrative overhead, premises leases and
bad debts. We expect that these costs will grow significantly as we expand our
operations and that sales and marketing and administrative overhead will be a
large portion of these expenses during the start-up phase in each of our new
markets.

Results of Operations

   The following table summarizes the results of operations as a percentage of
revenues for:

  (1) Our predecessor's telephone and answering service divisions for the
      nine month period ended September 30, 1996 and Pac-West for the period
      from our commencement on October 1, 1996 to December 31, 1996 on a
      combined basis; and

  (2) Pac-West for the years ended December 31, 1997 and 1998 and for the
      unaudited six month periods ended June 30, 1998 and 1999.

The "Combined" column in the following table combines the results of operations
of our predecessor's telephone and answering service divisions for the nine
month period ended September 30, 1996 with those of Pac-West for the period
from our commencement on October 1, 1996 to December 31, 1996. Due to the
significant changes in our operations since September 30, 1996, we believe that
the financial information of our predecessor telephone and answering service
divisions is not directly comparable to our results of operations. As a result,
prospective investors are cautioned not to place undue reliance on such
financial information. The following data should be read in conjunction with
the financial statements and notes thereto included elsewhere in this
prospectus.

   Selling, general and administrative expenses and income from operations for
the year ended December 31, 1998 include $3.8 million of one-time transaction
bonuses and consultant's costs. Excluding these transaction bonuses and
consultant's costs, selling, general and administrative expenses were 25.5% of
revenues and

                                       24
<PAGE>

income from operations was 28.4% of revenues for that period. The net loss for
1998 includes the costs of the recapitalization of $3.0 million, transaction
bonuses and consultant's costs of $3.8 million and the extraordinary loss on
early extinguishment of debt of $0.7 million before income tax benefit.

 Six Month Period Ended June 30, 1999 Compared to Six Month Period Ended June
 30, 1998

   Revenues for the six month period ended June 30, 1999 increased $10.4
million to $30.3 million from $19.9 million for the corresponding period in
1998. The increase in revenues was primarily attributed to an increase of $5.3
million in paid local interconnection revenues and an increase of $4.1 million
in recurring charges and installation charges billed directly to Internet
service providers.

   In the third quarter of 1998, we installed new higher capacity switches at
our Stockton and Los Angeles switching sites. During the fourth quarter of
1998, we expanded switch capacity to existing and new customers. In the second
quarter of 1999, we activated a new higher capacity switch in Oakland and
continued to expand our switching capacity in Los Angeles. Our revenues for the
second quarter of 1999 significantly increased compared to the second quarter
of 1998 as a result of additional switch capacities, and increased utilization
of our expanded switch capacities, primarily attributable to Internet service
provider customers. In addition, new service orders from small and medium
businesses have continued to accelerate in the second quarter of 1999 as we
have built our sales force.

   The number of access lines in service increased 137% to 76,263 as of June
30, 1999 from 32,176 as of June 30, 1998. Billable minutes of use were 6.6
billion in the first half of 1999, up 105% from 3.2 billion for the first half
of 1998.

   Inbound local calls and minutes subject to reciprocal compensation revenues
in accordance with interconnection agreements increased 65% and 106%,
respectively, for the first half of 1999 over the first half of 1998. However,
for reasons discussed elsewhere in this prospectus, the incumbent local
exchange carriers paid only 31% of the reciprocal compensation billings for the
first half of 1999 as compared to paying 36% in 1998. The net effect of those
significant increases in inbound local calls and minutes, offset by the lower
payment percentage, resulted in the $5.3 million or 72% increase in paid
interconnection revenues.

   The $4.1 million increase in the first half of 1999 over the first half of
1998 in direct billings to Internet service providers represented a 94% year to
year increase. Lines used by our Internet service providers significantly
increased in the first half of 1999 over the same period in 1998 to 60,401
lines in service by Internet service providers at June 30, 1999, from 28,108
lines in service at June 30, 1998.

   Our operating costs for the six month period ended June 30, 1999 increased
$1.0 million to $8.8 million from $7.8 million for the corresponding period in
1998. Our operating costs as a percentage of revenues decreased to 28.9% for
the six month period ended June 30, 1999 from 39.1% for the corresponding
period in 1998. The increase in operating costs was primarily due to an
increase in network operations associated with a higher level of
telecommunications activity. We made significant investments in our telephone
infrastructure during the second half of 1998 and the first half of 1999 to
accommodate future growth of our communications services. As a result of
increased utilization of our newly installed switching equipment and the use of
higher capacity transmission facilities, our operating costs decreased as a
percentage of revenues.

                                       25
<PAGE>

   Our selling, general and administrative expenses for the six month period
ended June 30, 1999 increased $5.4 million to $9.6 million from $4.2 million
for the corresponding period in 1998. As a percentage of revenues, our selling,
general and administrative expenses increased to 31.6% for the six month period
ended June 30, 1999 from 21.2% in the corresponding period in 1998. The
increase in selling, general and administrative expenses was primarily due to
the addition of 36 employees in sales and marketing; an increase in network
operational, development and administration costs, including 21 additional
network employees; an increase of 20 service technicians; and 11 additional
employees in other administration, customer service and information technology
functions. Our total number of our employees increased from 99 at June 30, 1998
to 187 at June 30, 1999.

   Our depreciation and amortization expense for the six month period ended
June 30, 1999 increased $1.6 million to $3.3 million from $1.7 million for the
corresponding period in 1998. Depreciation and amortization as a percentage of
revenues increased to 10.9% for the six month period ended June 30, 1999 from
8.5% in the corresponding period in 1998. The increase in depreciation and
amortization expense was primarily due to the additional depreciation on the
portion of the $42.5 million of equipment acquired during 1998 which has been
placed in service. As the equipment acquired in 1999 is placed in service,
depreciation expense as a percentage of revenues is expected to increase in
subsequent quarters.

   Our interest expense for the six month period ended June 30, 1999 increased
$7.7 million to $8.5 million from $0.8 million in the corresponding period in
1998. The increase in interest expense was primarily due to the financing of a
significant portion of the $42.5 million of equipment acquired during 1998 and
interest on the $150 million senior notes issued on January 29, 1999, including
amortization over 10 years of the related deferred financing costs associated
with that offering. In addition, the interest rate on the senior notes since
January 29, 1999 is a higher interest rate than the rates paid on the equipment
financings outstanding in the first half 1998.

   Our combined effective federal and state tax rate was 40% for the first half
of both 1999 and 1998.

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

   Our revenues for the year ended December 31, 1998 increased $12.6 million to
$42.2 million from $29.6 million for 1997. The increase in revenues was
primarily attributed to an increase of $4.6 million in paid interconnection
revenues, an increase of $5.1 million in recurring charges and installation
charges billed directly to Internet service providers, an increase of $1.2
million in local and long distance usage revenues, and an increase of $0.8
million in dedicated transport revenues.

   Inbound local calls and minutes subject to reciprocal compensation revenues
in accordance with interconnection agreements increased 128% and 232%,
respectively, 1998 over 1997. However, for reasons discussed elsewhere in this
prospectus, the incumbent local exchange carriers paid only 32% of the
reciprocal compensation billings in 1998 as compared to paying 74% in 1997. The
net effect of these significant increases in inbound local calls and minutes,
partially offset by the significantly lower payment percentage, resulted in the
$4.6 million or 42% increase in paid interconnection revenues.

   The $5.1 million increase in 1998 over 1997 in direct billings to Internet
service providers represented a 106% year over year increase. Lines used by our
Internet service providers significantly increased from 1997 to 1998, from
18,430 lines in service by Internet service providers at December 31, 1997 to
41,135 lines in service at December 31, 1998.

   The $1.2 million increase in outbound local and long distance revenues,
including 800 number and travel card calls, represented a 23% increase in 1998
over 1997. This increase is directly related to our focus on providing services
to high-volume, telecommunication intensive users and to small and medium
businesses.

   The $0.8 million or 25% increase in dedicated transport revenues primarily
related to increased data networking services for private corporate networks.

   Our operating costs for the year ended December 31, 1998 increased $3.2
million to $15.3 million from $12.1 million for 1997. Our operating costs as a
percentage of revenues decreased to 36.4% for the year ended December 31, 1998
from 40.8% for 1997. The increase in operating costs was primarily due to an
increase in network operations associated with the higher level of revenues. We
made significant investments in our telephone infrastructure beginning in the
second half of 1996 through 1998 to accommodate future growth of competitive
local exchange carrier services. As a result of increased utilization of our
newly installed switching equipment and the use of higher capacity transmission
facilities, our operating costs decreased as a percentage of revenues.

   Excluding $3.8 million of bonuses paid to certain key executives in
connection with their assistance with our recapitalization and consulting
payments made to our current President in connection with services provided by
him prior to his joining Pac-West, our selling, general and administrative
expenses for the year ended December 31, 1998 increased $3.4 million to $10.8
million from $7.4 million for 1997. Excluding the $3.8 million of transaction
bonuses and consultant's costs, our selling, general and administrative
expenses as a percentage of revenues increased to 25.5% for the year ended
December 31, 1998 from 24.9% in 1997. Selling, general and administrative
expense in 1998 reflects a 79% increase in the number of employees, a $0.6
million increase in facility costs and a $1.6 million increase in payroll costs
related to the increased hiring of technology, sales, administrative and
support personnel.

   Our depreciation and amortization expense for the year ended December 31,
1998 increased $1.9 million to $4.1 million from $2.2 million for 1997.
Depreciation and amortization as a percentage of revenues increased to 9.7% for
the year ended December 31, 1998 from 7.5% in 1997. The increase in
depreciation and amortization expense was primarily due to the additional
depreciation on the $7.7 million of equipment acquired during the second half
of 1997 and the $20.1 million of equipment acquired during the first nine
months of 1998.

   Our interest expense for the year ended December 31, 1998 increased $3.3
million to $4.2 million from $0.9 million in 1997. The increase in interest
expense was primarily due to an increase in long-term debt during 1998. The
increase in long-term debt in 1998 was primarily due to $10.5 million of new
borrowings during the year to finance the purchase of network equipment, and
due to incremental borrowings of approximately $53.0 million in connection with
the merger and recapitalization.

   Our tax provision for 1998 reflects the impact of the nondeductibility of a
substantial portion of the costs associated with the recapitalization.
Excluding the impact of these one-time costs, our combined effective federal
and state tax rate for 1998 was 40%, consistent with 1997's effective tax rate.

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

   Our revenues for 1997 increased $16.6 million to $29.6 million from $13.0
million in 1996. The increase in revenues was primarily attributed to an
increase of $10.4 million in local interconnection revenues, an increase of
$3.7 million in recurring charges and installation charges billed directly to
Internet service providers, an increase of $0.7 million in local and long
distance usage revenues and an increase of $1.0 million in dedicated transport
revenues.

   Both local interconnection revenues and billings to Internet service
providers were new types of revenues in mid 1996 with less than $1.0 million of
each type of revenue being recorded in 1996. Local and long distance usage
revenues increased 15% in 1997 over 1996, which increase was due to our focus
on business customers. Dedicated transport revenues increased 42% in 1997 over
1996 primarily due to increased data networking services for private corporate
networks.

   Our operating costs for 1997 increased $5.8 million to $12.1 million from
$6.3 million in 1996. Our operating costs as a percentage of revenues decreased
to 40.8% in 1997 from 48.3% in 1996. The decrease in operating costs as a
percentage of revenues was primarily due to an increase in revenues from
higher-margin, competitive local exchange carrier related services.

                                       27
<PAGE>

   Our selling, general and administrative expenses increased $2.8 million to
$7.4 million from $4.6 million in 1996. Our selling, general and administrative
expenses as a percentage of revenues decreased to 24.9% for the year ended
December 31, 1997 from 35.8% for 1996. The increase in selling, general and
administrative expenses was primarily due to an increase in hiring of
additional sales, marketing and administrative personnel and a $0.5 million
increase in facility costs. The decrease in selling, general and administrative
expenses, as a percentage of revenues, was primarily due to the lower selling
and marketing expenses associated with the addition of Internet service
provider customers and a rapid increase in revenues from Internet service
provider customers.

   Our depreciation and amortization expense in 1997 increased $1.4 million to
$2.2 million from $0.8 million in 1996. Depreciation and amortization as a
percentage of revenues increased to 7.5% for the year ended December 31, 1997
from 6.5% in 1996. The increase in depreciation and amortization expense was
primarily due to the additional depreciation on the $3.9 million of equipment
acquired during the fourth quarter of 1996 and the $11.9 million of capital
equipment acquired during 1997.

   Our interest expense in 1997 increased $0.8 million to $0.9 million from
$0.1 million in 1996. The increase in interest expense was primarily due to the
additional interest expense on the $4.7 million of equipment financings entered
into during the fourth quarter of 1996 and $10.7 million of equipment
financings entered into during 1997. Total debt increased from $7.0 million at
December 31, 1996 to $15.7 million at December 31, 1997.

   Our combined effective federal and state tax rate was 40% for both 1997 and
1996.

Liquidity and Capital Resources

   Net cash provided by operating activities was $20.7 million for the six
month period ended June 30, 1999 compared to $7.4 million for the six month
period ended June 30, 1998. This increase primarily reflects an increase in
accounts payable for new switching equipment received in late June 1999 plus
$8.5 million of accrued interest on our senior notes. Net cash provided by
operating activities was $12.0 million for the year ended December 31, 1998
compared to $5.9 million for the year ended December 31, 1997. This increase
primarily reflects increased accounts payable and accrued liabilities of $5.9
million. Net cash provided by operating activities for the period from our
commencement on October 1, 1996 to December 31, 1996 and for our predecessor's
telephone and answering service divisions for the nine month period ended
September 30, 1996 was $75,000 and $1,092,000, respectively.

                                       28
<PAGE>

   Net cash used in investing activities was $41.6 million for the six month
period ended June 30, 1999 compared to $7.4 million for the six month period
ended June 30, 1998. During the six month period ended June 30, 1999, we
invested $21.9 million in new switching and related equipment as compared to
$7.9 million during the comparable 1998 period. Further, in the first half of
1999, $19.7 million of the proceeds from the issuance of our senior notes was
used to purchase short-term investments to fund the interest reserve trust
account for the notes. Net cash used in investing activities was $42.0 million
for the year ended December 31, 1998 compared to $6.6 million for the year
ended December 31, 1997. During 1998, we invested approximately $41.0 million
in new switching and related equipment and leasehold improvements to expand
switching capacity in Los Angeles, Oakland and Stockton, California. During
1997, our investment of approximately $6.7 million in new switching and related
equipment and leasehold improvements was partially offset by $0.5 million of
proceeds from the disposition of assets. Net cash used in investing activities
for the period from our commencement on October 1, 1996 to December 31, 1996
and for our predecessor's telephone and answering service divisions for the
nine month period ended September 30, 1996 were $1.7 million and $2.5 million,
respectively.

   Net cash provided by financing activities was $44.5 million for the six
month period ended June 30, 1999 compared to $3.0 million for the six month
period ended June 30, 1998. The net cash provided in the six month period ended
June 30, 1999 was primarily attributable to proceeds from the issuance of $150
million of our senior notes reduced by the payoff of $100 million of senior
secured borrowings. Net cash provided by financing activities was $41.6 million
for the year ended December 31, 1998 compared to $3.7 million for 1997. The net
cash provided in 1998 was primarily attributable to $37.8 million of proceeds
from the sale of our common and convertible redeemable preferred stock, $75.4
million of proceeds from senior secured borrowings in connection with the
recapitalization, less $74.0 million of payments to existing stockholders. See
"Certain Relationships and Related Transactions--Recapitalization." Net cash
provided by financing activities for the period from our commencement on
October 1, 1996 to December 31, 1996 and for our predecessor's telephone and
answering service divisions for the nine month period ended September 30, 1996
was $1.5 million and $1.8 million, respectively.

   The local telecommunications services business is capital intensive. Our
operations have required and will continue to require substantial capital
investment for the design, acquisition, construction and implementation of our
network. Capital expenditures, including amounts financed under capital leases,
were $21.9 million for the first half of 1999, $42.5 million for the year ended
December 31, 1998, $11.9 million for the year ended December 31, 1997 and $3.9
million for the period from our commencement on October 1, 1996 to December 31,
1996. Of the $42.5 million of capital expenditures during 1998, $25.6 million
was included in construction in progress at December 31, 1998 and therefore is
not being depreciated until placed in service in 1999. We expect to make
additional capital expenditures between $20 and $30 million during the balance
of 1999. Planned capital expenditure projects during the remainder of 1999
include: completion of an upgraded and expanded switch at the existing Oakland,
California facility; construction of switching facilities in Seattle,
Washington; addition of a second switch in Los Angeles, California; and
implementation of a new billing and operations support system. Our business
plan, as currently contemplated, including the capital expenditures for the
remainder of 1999, anticipates capital expenditures of approximately $175
million through 2001. The actual cost of our planned expansion will depend on a
variety of factors, including the cost of the development of our network in
each of our new markets, the extent of competition and pricing of the
telecommunications services in such markets, and the acceptance of our
services. Accordingly, our actual capital requirements may exceed the amounts
described above.

   Our senior credit facility provides for maximum borrowings of $40.0 million
for working capital and other general corporate purposes, and bears interest,
at our option, at:

  (1) the base rate, as defined in the senior credit facility; or

  (2) the LIBOR rate, as defined in the senior credit facility, plus between
      2.25% and 3.5%.

                                       29
<PAGE>

As of June 30, 1999, there were no amounts outstanding under this facility and
the borrowing rate would have been approximately 8.0%. Our borrowings under the
senior credit facility will be secured by all of our assets. The senior credit
facility has a three year term. See "Description of Indebtedness."

   Our principal sources of funds following this offering are anticipated to be
current unrestricted cash balances, cash flows from operating activities,
borrowings under the senior credit facility and restricted cash. We believe
that these funds together with the net proceeds to us from this offering will
provide us with sufficient liquidity to fund our business plan through 2001. No
assurance can be given, however, that this will be the case. Depending upon our
rate of growth and profitability, especially if we pursue any significant
acquisitions, we may require additional equity or debt financing to meet our
working capital requirements or capital equipment needs. There can be no
assurance that additional financing will be available when required or, if
available, will be on terms satisfactory to us.

   Instruments governing our indebtedness, including the senior credit facility
and the senior notes indenture, contain financial and other covenants that
restrict, among other things, our ability to incur additional indebtedness,
incur liens, pay dividends or make certain other restricted payments,
consummate certain asset sales, enter into certain transactions with
affiliates, merge or consolidate with any other person or sell, assign,
transfer, lease, convey or otherwise dispose of substantially all of our
assets. Such limitations, together with our highly leveraged nature, could
limit corporate and operating activities, including our ability to respond to
market conditions to provide for unanticipated capital investments or to take
advantage of business opportunities. We have purchased and pledged to the
trustee for the benefit of the holders of the notes approximately $19.7 million
of U.S. government securities to provide for the payment of the first two
scheduled interest payments on our senior notes, the first of which was paid on
August 2, 1999. These U.S. government securities are classified as restricted
cash.

Quantitative and Qualitative Disclosures About Market Risks

   The SEC's rule related to market risk disclosure requires that we describe
and quantify our potential losses from market risk sensitive instruments
attributable to reasonably possible market changes. Market risk sensitive
instruments include all financial or commodity instruments and other financial
instruments that are sensitive to future changes in interest rates, currency
exchange rates, commodity prices or other market factors. We are not exposed to
market risks from changes in foreign currency exchange rates or commodity
prices. We do not hold derivative financial instruments nor do we hold
securities for trading or speculative purposes. At December 31, 1998, we had
$100 million of long-term debt and other long-term obligations subject to
variable interest rates. However, all of this $100 million was replaced by the
issuance of $150 million of fixed rate notes in January 1999, and consequently
we currently have no risk exposure associated with changing interest rates on
debt. We are exposed to changes in interest rates on our investments in cash
equivalents. All of our investments in cash equivalents are in money market
funds that hold short-term investment grade commercial paper, treasury bills or
other U.S. government obligations. Therefore this investment policy reduces our
exposure to long-term interest rate changes. Under our current policies, we do
not use interest rate derivative instruments to manage our exposure to interest
rate changes. A hypothetical 100 basis point decline in short-term interest
rates would reduce the annualized earnings on our $38.9 million of cash
equivalent investments at June 30, 1999 by approximately $389,000. We do,
however, have market risk exposure associated with the market price on the $150
million of our senior notes outstanding. These notes are recorded at book value
which could vary from current market prices in the future, especially if
interest rates decline. As of June 30, 1999, the market value of the notes
approximated their book value.

Inflation

   We do not believe that inflation has had any material effect on our business
over the past three years.

Year 2000 Issues

   Year 2000 Compliance Issues. The information in this section is a "Year 2000
Readiness Disclosure" as defined in the Year 2000 Information and Readiness
Disclosure Act of 1998 and contains forward-looking statements. These
statements include, but are not limited to, anticipated costs and the date by
which we expect to complete actions and are based on management's current
estimates, which are in turn based on assumptions about future events,
including, but not limited to, the availability of resources, representations
received from third parties and other factors. There can be no guarantee that
these estimates will be achieved, and actual results could differ materially
from those anticipated. Specific factors that might cause material differences
include, but are not limited to, our ability to identify and remediate all
relevant systems, results of Year 2000 testing, adequate resolution of Year
2000 issues by business and other third parties that are service providers,
suppliers and customers of ours, unanticipated system costs, the adequacy of
and ability to implement contingency plans and similar uncertainties. The
forward-looking statements made in this Year 2000 discussion speak only as of
the date on which these statements are made.

   Impact of the Year 2000 computer problem. The Year 2000 computer problem
refers to the potential for system and processing failures of date-related data
as a result of computer-controlled systems using two digits rather than four to
define the applicable year. For example, computer programs that have time-
sensitive software may recognize a date represented as "00" as the year 1900
rather than the Year 2000. This could result in a system failure or
miscalculations causing disruptions of operations, including among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities. To date, we have not experienced any
Year 2000 issues with any of our internal systems or our products, and we do
not expect to experience any of them.

   Assessment. The Year 2000 problem affects the computers, software and other
equipment that we use, operate or maintain for our operations. Accordingly, we
have organized a program team responsible for monitoring the assessment and
remediation status of our Year 2000 issues and reporting to our management.
This project team is currently assessing the potential effect and costs of
remediating Year 2000 issues for our internal systems. To date, we have not
obtained independent verification or validation to assure the reliability of
our risk and cost estimates because we do not feel that the scope of our
program warrants this time and expense.

   Internal infrastructure. We believe that we have identified all major
computers, software applications and related equipment used in connection with
our internal operations that will need to be evaluated to determine if they
must be modified, upgraded or replaced to minimize the possibility of a
material disruption to our business. We have completed assessing the potential
impact of Year 2000 issues on these computers, equipment and applications and
are currently modifying, upgrading and replacing major systems that we believe
have Year 2000 issues. Our long distance billing system and our accounting
system are not yet Year 2000 compliant. We are in process of replacing our
billing system to accommodate future anticipated growth with a new Year 2000
compliant system. The manufacturer of the noncompliant accounting system has
provided software that is represented to be Year 2000 compliant.

   Systems other than information technology systems. In addition to computers
and related systems, the operation of office and facilities equipment, such as
fax machines, security systems and other common devices may have Year 2000
issues. We are currently assessing the potential effect on and the costs of
remediating these issues, if any, for our office equipment and our facilities
in Stockton, Los Angeles, and Oakland, California and Las Vegas, Nevada.

   Products. We have designed our products to be Year 2000 compliant and
believe that using our products as documented should not cause any Year 2000-
related issues. We have tested and intend to continue to test all of our
products for Year 2000 issues. While we believe our products are Year 2000
compliant, it is impractical for us to test our products in every
telecommunications systems environment or with all available combinations of
our products with components supplied by our customers or other third party
suppliers. As a result, there may be situations where the combination of our
products working with components supplied by other third parties could result
in Year 2000 issues.

                                       31
<PAGE>

   Costs of remediation. We currently anticipate that our total cost of
addressing our Year 2000 issues will be $150,000, of which approximately
$110,000 has been incurred and expensed through June 30, 1999. We do not have a
separate information technology or similar budget. The cost of addressing Year
2000 issues will be reported as a general and administrative expense. We have
not deferred any material information technology projects due to our Year 2000
efforts. Since we have been working on a Year 2000 resolution for over one
year, all major decisions regarding replacement of equipment and software was
done with Year 2000 compliance as a major purchase criteria. Costs of software
upgrades and additions, as well as hardware upgrades which were required for
compatibility, enhancement, capability/capacity, or efficiency were not
considered as a Year 2000 cost.

   Suppliers. We are contacting third-party suppliers of components and our key
subcontractors used in the manufacture of our products to identify, and to the
extent possible, resolve issues relating to the Year 2000 issue. While we
expect that we will be able to resolve any significant Year 2000 issue
identified with these third parties, because we have no control over the
actions of these parties, these third parties may not remediate any or all of
the Year 2000 issues identified. Any failure of any of these third parties to
timely resolve Year 2000 issues with either their products sold to us, or their
systems could have a material adverse effect on our business, operating results
and financial condition. We believe that many incumbent local exchange carriers
and long distance carriers are also impacted by the Year 2000 issue, which in
turn could affect us.

   Most reasonably likely worst case consequence of Year 2000 issues. We expect
to identify and resolve all Year 2000 issues that could materially adversely
affect our business operations. However, for the reasons discussed above, we
believe that it is not possible to determine with complete certainty that all
Year 2000 issues affecting us have been identified or corrected. As a result,
we believe that the following consequences are possible:

  . operational inconveniences and inefficiencies for us, our contract
    manufacturers and our customers that will divert our management's time
    and attention and our financial and human resources from ordinary
    business activities;

  . business disputes and claims for pricing adjustments or penalties by our
    customers due to Year 2000 issues, which we believe will be resolved in
    the ordinary course of business; and

  . business disputes alleging that we failed to comply with the terms and
    conditions of contracts or industry standards of performance that result
    in litigation on contract termination.

   Contingency plans. We are currently developing contingency plans to be
implemented if our efforts to identify and correct Year 2000 issues affecting
our internal systems are not effective. We expect to complete our contingency
plans by the end of October 1999. Depending on the systems affected, these
plans could include:

  . accelerated replacement of affected equipment or software;

  . short to medium-term use of backup equipment and software;

  . increased work hours for our personnel; and

  . use of contract personnel to correct on an accelerated schedule any Year
    2000 issues that arise or to provide manual workarounds for information
    systems.

   Our implementation of any of these contingency plans could have a material
adverse effect on our business, operating results and financial conditions.

New Accounting Pronouncements

   In June 1998, the FASB issued Statement of Financial Accounting Standards
Statement No. 133, Accounting for Derivative Instruments and for Hedging
Activities. Statement No. 133 is effective for years beginning after June 15,
1999. Statement No. 133 provides a comprehensive and consistent standard for
the recognition and measurement of derivatives and hedging activities. We do
not anticipate that the adoption of Statement No. 133 will have a material
impact on our financial position or the results of our operations.

                                    BUSINESS

Our Company

   We are a rapidly growing provider of integrated communications services in
the western United States. Our customers include Internet service providers,
small and medium businesses, and enhanced communications service providers,
many of which are communications-intensive users. We built our network to
capitalize on the significant growth in national Internet usage and in the
related demand for local telephone service by Internet service providers, as
well as the increasing demand of small and medium businesses for customized and
integrated communications services. We believe the structure of our network
and, in California, our presence in each local access and transport area,
provide us with significant competitive advantages over incumbent local
exchange carriers and other competitive local exchange carriers, particularly
for Internet service providers. In California, our network enables these
companies to provide their business and residential customers with access to
Internet, paging and other data and voice services from almost any point in the
state through a local call. We believe the breadth of our product offerings and
the structure of our network enable us to generate high network utilization,
substantial revenues, strong profit margins and positive cash flows.

Markets

   According to data published by the FCC, total local exchange service
revenues, including business and residential services in the United States,
were approximately $103.0 billion in 1997. We believe that the rapid opening of
local markets to competition, accelerated growth in local traffic related to
increases in Internet access, and the desire for one-stop integrated services
by small and medium businesses present a significant opportunity for new
entrants to achieve significant penetration of this large, established market.
We believe that the primary determinants of success will be the construction of
a network that meets the needs of target customers, rapid deployment of network
assets, building of a direct local sales force to market to small and medium
businesses and the ability to provide competitively priced services.

   We own and operate switches in Los Angeles, Oakland and Stockton, California
and have local points of presence in all 11 California local access and
transport areas with over 500 assigned local prefixes and 5.0 million telephone
numbers available for use. Pac-West's local prefixes presently cover
approximately 400 California rate areas and allow virtually all California
callers to access our network through a local call. Industry sources indicate
that the California market generated approximately $27.2 billion in local
exchange and long distance revenues in 1997 and currently has 1,176 Internet
service providers, over 600,000 small and medium businesses and about 8.4
million total business lines. We are expanding our network into Nevada with a
switch in Las Vegas and digital connections in all of Nevada's local access and
transport areas. We expect to have ten switches with operations in ten western
states, including California, Nevada, Arizona, Washington, Colorado, Texas,
Utah, Idaho, New Mexico and Oregon, by the end of 2000. We believe that the use
of communications services is rapidly expanding in each of these areas and that
we will be able to effectively use our experience in California and our
customer relationships to enter these markets.

   The following table sets forth certain information regarding the markets in
which Pac-West currently operates and our anticipated geographic network
buildouts. Internet service providers are often present in more than one state
and are therefore included in the total for each such state. Small and medium
businesses are defined as businesses with fewer than 100 employees. The
following information is taken from the electronic publication "Boardwatch.com"
and publications issued by the FCC and United States Small Business
Administration.

Network

   We built our network to capitalize on the significant growth in demand for
switched data and voice communications and the increasing demands of small and
medium businesses for customized, integrated communications services. Since our
inception, we have used a "smart-build" strategy, building and owning
intelligent components of our network while leasing unbundled loops and
transport lines from other carriers. We believe that this strategy has provided
us with significant cost and time-to-market advantages over competitors that
own both their switches and fiber lines. By owning our switches, we can
configure our network to provide high performance, high reliability and cost-
effective solutions for our customers' needs. By leasing our transport lines,
we can reduce up-front capital expenditures, rapidly enter new markets, and
provide low-cost redundancy. In addition, we seek to maximize our operating
profits by carrying a high percentage of our customer-originated traffic on our
network. As traffic on our network increases, we intend to purchase rights of
use in high capacity dark fiber transport lines to interconnect certain of our
markets with an owned backbone network. This will provide us with greater
flexibility in creating and managing data and voice services and result in cost
savings.

   To meet demand for communications services in California, we have
established three California switching sites, one in each of Los Angeles,
Oakland, and Stockton, and digital connections in each of California's 11 local
access and transport areas. We believe the structure of our network and, in
California, our presence in each California local access and transport area
provides us with significant competitive advantages over incumbent local
exchange carriers and other competitive local exchange carriers, particularly
for Internet service providers, small and medium business and enhanced
communications service providers. In California, our network enables our
customers to provide their business and residential customers with access to
Internet, paging and other services from almost any point in the state through
a local call. In this way, our customers can achieve statewide coverage with
significantly lower capital and operating expenses. We currently aggregate and
concentrate all of our network traffic into our high volume switching sites
called Super POPs. Our switching sites offer Internet service providers highly
reliable, low cost tandem switching and the ability to build lower cost
networks by collocating equipment at our three California switching sites
rather than in all 11 local access

                                       35
<PAGE>

and transport areas. In addition, our interconnection arrangements and
statewide leased transport network allow Internet service providers to obtain
statewide coverage at local calling rates, which reduces switching and
transmission costs.

   As of June 30, 1999, we had an installed capacity of 309,120 ports in
California and Nevada. We expect to have ten switches with operations in ten
western states by the end of 2000 with statewide local coverage in each of our
target markets. We intend to install a second switch in Los Angeles in late
1999 as well as build switching sites in Washington in 1999 and in Colorado in
early 2000.

   Switching Platform. We have chosen Alcatel USA's digital tandem switches to
switch calls between originating locations and final destinations. Due to their
high call carrying capacity, multiple path call routing capabilities and
ability to switch multiple digital, voice and data applications of varying
bandwidths, tandem switches are ideally suited for handling the high volumes
and long holding times involved in serving Internet service provider customers.
Tandem switches, software and customer collocation facilities provide the
scale, switching capacity and standardization needed to efficiently and
reliably serve our target customers. Our uniform and advanced switching
platform combined with the structure of our computer network enable us to:

  . deploy features and functions quickly throughout our entire network;

  . expand switch and transport capacity in a cost-effective, demand-based
    manner;

  . lower maintenance costs through reduced training and spare parts
    requirements; and

  . achieve direct connectivity to wireless and other personal communication
    system applications in the future.

   Transmission Capacity. We currently lease our transmission facilities from
inter-exchange carriers, incumbent local exchange carriers and other
competitive local exchange carriers. We generally seek to lease fiber optic
transmission facilities from multiple sources in each of our current and target
markets. We believe that our broad market coverage results in:

  (1) an increased number of buildings that can be directly connected to our
      switching network, which should maximize the number of customers to
      which we can offer our services;

  (2) a higher volume of communications traffic both originating and
      terminating on our network, which should result in improved operating
      margins;

  (3) enhanced reliability at competitive prices;

  (4) the ability to leverage our investment in high capacity switching
      equipment and electronics; and

  (5) the opportunity for our network to provide backhaul carriage for other
      telecommunications service providers, such as long distance and
      wireless carriers.

   Interconnection. Our primary interconnection agreements are with Pacific
Bell and GTE. Our interconnection agreement with GTE has expired and is
currently being renegotiated. In accordance with its terms, however, this
agreement will remain in force during renegotiation. We believe that
interconnection arrangements between the incumbent local exchange carriers and
other competitive local exchange carriers will be in place at appropriate times
in other markets that we may enter. Interconnection agreements between us and
incumbent local exchange carriers are subject to approval of the relevant state
commission, and under the terms of the Telecommunications Act of 1996, each
incumbent local exchange carrier which is subject to the Telecommunications Act
of 1996 is required to negotiate an interconnection agreement with us. Where an
interconnection agreement cannot be reached on terms and conditions
satisfactory to us, we may pursue arbitration of any disputes before the state
utility commissions as provided under the Telecommunications Act of 1996. Pac-
West currently is in arbitration with Citizens Telecommunications Company of
California, Inc. See "--Regulatory Proceedings--Interconnection Agreements."

Strategy

   We are focused on becoming the integrated communications provider of choice
for our customers. Our strategy to meet this objective is to:

   Capitalize on growing demand in our current markets. The demand for data and
voice communication services in our current markets is large and growing
rapidly. Significant increases in dial-up access to the Internet have resulted
in the creation of over 5,000 Internet service providers in the United States,
which, in turn, has created strong demand for local access lines nationwide. We
intend to increase our market penetration and capitalize on this growth in our
current markets by adding more switches and transport lines to increase our
capacity, adding new and innovative products to our existing offerings, and
repackaging and repricing our offerings in response to the changing demands of
our customers. In addition, we believe that we are differentiated by the
architecture of our network, which offers the following benefits:

  . switching systems which support high calling volumes and long holding
    times for Internet service provider calls;

  . statewide local calling capabilities through established physical
    locations in each local access and transport area within a state, which
    reduces Internet service providers' transmission costs; and

  . the ability to collocate Internet modems and servers in fewer locations,
    which enables Internet service providers to achieve broad geographic
    coverage while minimizing capital expenditures.

   Leverage existing customer base through geographic expansion. We are a
leading supplier of Internet access and other Internet infrastructure services
in California with 78 Internet service providers, all of which have operations
in California, including Concentric Network Corp., EarthLink, Inc., MindSpring
Enterprises, Inc. and Splitrock Services, Inc. We plan to leverage the
expansion of these customers into other western states by entering new markets
where our current customers have or are beginning operations. In addition, we
refine our selection of target markets based on a number of considerations,
including the number of potential customers and other competitors in those
markets and the presence of multiple transmission facility suppliers. Our
target markets have approximately 2,300 Internet service providers,
approximately 1.4 million small and medium businesses, 16.5 million business
lines and generated approximately $63.4 billion of local exchange and long
distance revenues in 1997. We believe that our geographically clustered network
will enable us to take advantage of regional calling patterns to transmit a
large percentage of customer traffic on our network. We also believe that by
originating and terminating calls on our network, we can continue to achieve
significant cost savings and may develop some pricing advantages over our
competition.

   Focus on the small and medium business market. We believe that small and
medium businesses have significant and increasing needs for advanced
communication services. Many of our target customers want technologically
advanced communications systems along with low cost bundled local, long
distance, data and other enhanced services but do not have the expertise to
design, purchase and maintain these kinds of systems and services themselves.
We believe that these target customers are not adequately served by incumbent
local exchange carriers and other competitive local exchange carriers. We
intend to become a leading provider of integrated communications services to
small and medium businesses by offering a complete product offering of system
design, equipment installation and maintenance, voice, data and long distance
services, 24/7 support, subscription services with multi-year contracts, and
optional upgrades to emerging state-of-the-art equipment. We believe that this
product mix will enable us to quickly penetrate target markets and build
customer loyalty.

   In addition, we have and will continue to expand our sales, customer care
and service delivery forces in selected markets. From June 30, 1998 to June 30,
1999, our sales, customer care and service delivery forces increased from 53 to
105 professionals. Of these resources, the direct sales force increased from 21
to 44 in the same period. We believe that employing a direct sales force and
independent sales agents with extensive local market and telecommunications
sales experience enhances the likelihood of success in new markets. Salespeople
with experience in a particular market provide us with extensive knowledge of
our target customer base through existing relationships with target customers.
As a result, our salespeople are able to pre-sell our products and services
before we initiate network operations in a particular market.

                                       37
<PAGE>

   Expand portfolio of products and services. In order to achieve our growth
objectives, we expect to continue introducing new and innovative products and
services. We recently added several new products to our portfolio, including:

  . managed modem, a packaged product that includes incoming call access
    lines, modems, routers, and authentication services. This product
    provides Internet service providers and business customers with a non-
    capital intensive means of quickly establishing a local point of presence
    or POP throughout our coverage area.

  . remote access services, including mobile or remote office, virtual
    office, distance learning and training, and telecommuting. These services
    include Internet protocol fax, voice mail, paging, integrated messaging,
    and local area network and virtual private network, or VPN, services.
    This allows customers to access and interact with home or branch office
    communications and information systems from anywhere in our market area
    through a local call.

  . high-speed data services. We currently offer high-speed private line data
    services and digital subscriber line services to our customers. We also
    intend to explore wireless and satellite technologies in order to develop
    an array of high-speed alternatives for our customers.

   Expand through potential strategic acquisitions. We may acquire other
competitive local exchange carriers or other communications providers to grow
our business. We believe that strategic acquisitions may enable us to
accelerate our market penetration, cross-sell additional services, diversify
our customer base and improve operating profitability.

Products and Services

   Our products and services are designed to appeal to the sophisticated
telecommunications needs of our target customers.

   Local Services. We provide local dial-tone services to customers, allowing
them to complete calls in a local calling area and to access long distance
carriers. Local services and long distance services can be bundled together
using the same transport facility. Our network is designed to allow a customer
to easily increase or decrease capacity and alter enhanced communications
services as the communications requirements of the business change. In addition
to our core local services, we also provide access to third party directory
assistance and operator services.

   Long Distance Services. We provide domestic and international long distance
services. Long distance calls which do not terminate on our network are passed
to long distance carriers which route the remaining portion of the call. Our
ability to integrate local and long distance services allows us to aggregate
customers' monthly recurring, local usage and long distance charges on a
single, consolidated invoice.

   Specialized Application Services. We tailor products and services for target
industries with special communications needs. These services typically include
rated local calling, expanded local calling area, discounted long distance
rates and tailored trunking configurations.

   Internet Service Provider Services. We provide Internet service providers
collocation services at each of our switch locations. Collocation enables an
Internet service provider to install its equipment in any or all of our switch
facilities and interconnect directly to our tandem switches to switch calls
from their originating locations to their final destinations. Collocated
equipment is protected by the same cooling, power back-up and security systems
protecting our switches. In California, an Internet service provider's ability
to collocate equipment at only three sites, rather than in all 11 local access
and transport areas, reduces its capital expenditures and maintenance
requirements. We receive monthly rental revenue from the Internet service
provider for the space used. Pac-West is also in the process of introducing a
managed modem service where we provide modem pools and dedicated circuits into
the worldwide web for our Internet service provider customers.

                                       38
<PAGE>

   Enhanced Services. In addition to providing typical enhanced services such
as voicemail, call transfer and conference calling, we offer additional value-
added enhanced services to complement our core local and long distance
services. These enhanced service offerings include:

     Internet Access Services--Enables customers to use their available
  capacity for access to Internet service providers.

     Data Networking Services--We provide high-speed, broadband services to
  use for data communications, such as private corporate networks.

     Digital Subscriber Line Services--We offer high-speed digital subscriber
  line service to our Internet service provider and business customers
  through a reseller relationship with one or more major digital subscriber
  line supplier. Recently, we signed an agreement with Covad Communications
  to provide bundled high-speed services beginning in the fourth quarter of
  1999.

   Equipment Sales. System design and equipment sales and installation are
essential components of our strategy of marketing to medium and small
businesses. We offer our business customers technologically advanced systems
bundled together with local and long distance services.

Sales and Marketing

   Sales. We are building an experienced direct sales force. Our direct sales
force was increased to 44 as of June 30, 1999, from 21 as of June 30, 1998. We
recruit salespeople with strong sales backgrounds in our existing and target
markets, including salespeople from long distance companies, telecommunications
equipment manufacturers, network systems integrators and incumbent local
exchange carriers. We plan to continue to attract and retain highly qualified
salespeople by offering them an opportunity to work with an experienced
management team in an entrepreneurial environment and to participate in the
potential economic rewards made available through a results-oriented
compensation program that emphasizes sales commissions.

   During the months prior to initiating service in a new market, our
salespeople will begin pre-selling our services to target customers. This pre-
selling effort is designed to shorten the period between the availability of
service and the receipt of customer orders and to generate customers in each
market who may enter into service agreements before the local Pac-West network
becomes operational.

   Marketing. In our existing markets, we seek to position ourselves as a high
quality alternative to incumbent local exchange carriers for local
telecommunication services by offering network reliability and superior
customer support at competitive prices. We intend to build our reputation and
brand identity by working closely with our customers to develop services
tailored to their particular needs and by implementing targeted advertising and
promotional efforts, which will be gradually expanding to mass media.

   Customer and Technical Service. We believe that our ability to provide
superior customer and technical service is a key factor in acquiring new
customers and reducing churn of existing customers. We have developed a
customer service strategy designed to effectively meet the service requirements
of our target customers. The principal salesperson for each customer will
provide the first line of customer service by identifying and resolving any
customer concerns. Customer service representatives will provide real time
problem identification and resolution and superior customer service. All of
these services will be supported by our experienced engineering and technical
staff.

Customers

   We focus on providing integrated communications services to Internet service
providers, small and medium businesses, enhanced communications service
providers, paging companies and call centers, many of which are communications-
intensive users. For the three month period ended June 30, 1999, ten of our top
fifteen customers were Internet service providers. For the years ended December
31, 1997 and 1998 and for the six month period ended June 30, 1999, Internet
service providers accounted for approximately 16.2%, 23.3% and 28.2%,
respectively, of our revenues, not including reciprocal compensation related to
terminating calls to Internet service providers.

                                       39
<PAGE>

   In addition to Internet service providers, we have targeted enhanced
communications service providers as potential large volume users of our
services. Enhanced communications service providers offer unified messaging
platforms and fax mail services, in addition to recently introduced free fax
and voice mail services. The characteristics of this market segment not only
offer us the potential to sell more trunks and bill more minutes of use but
also allows us to improve the utilization of our resources.

   The following is a list of some of our Internet service providers, enhanced
communications service providers, and paging customers:

</TABLE>

   Our small and medium business customers include regional banks, alarm
companies, universities, healthcare providers, real estate agencies, law firms
and others including Bank of Stockton, Bay Alarm, Coldwell Banker GRUPE and
Re/Max of Modesto.

   Additional customer market segments we have targeted as potential large
volume users of our services include businesses with significant numbers of
telecommuters and businesses with substantial customer service call center
operations. Businesses with substantial numbers of telecommuters will be
targeted with our managed modem product, including our new 64k and 128k
integrated services digital network, or ISDN, service as well as our new
digital subscriber line service, to provide a secure, reliable, reasonably
priced remote access service to connect telecommuters with corporate local area
networks or LANs.

   We have also targeted businesses with substantial customer service call
center operations, including the banking, public utilities, and cable
television industries. Companies within these industries often send bills or
statements with a toll-free telephone number. With our services, these
companies can offer a local telephone number on bills and statements,
eliminating the need for the company to pay for toll-free service to enable
their customers to contact them.

   Sales to Bay Alarm Company and InReach Internet LLC collectively accounted
for approximately 7.1%, 6.4% and 4.4%, respectively, of our revenues for the
years ended December 31, 1997 and 1998 and for the six month period ended June
30, 1999. Mr. Bruce A. Westphal, who serves on our board of directors, is the
chairman of the board of both Bay Alarm Company and InReach Internet LLC.

Competition

   The telecommunications industry is highly competitive. We believe that the
principal competitive factors affecting our business will be pricing levels and
pricing policies, customer service, accurate billing, and, to a lesser extent,
variety of services. Our ability to compete effectively will depend upon our
continued ability to maintain high quality, market-driven services at prices
generally equal to or below those charged by our competitors. To maintain our
competitive posture, we believe that we must be in a position to reduce our
prices in order to meet reductions in rates, if any, by others. Any such
reductions could adversely affect us. Many of our current and potential
competitors have financial, personnel, and other resources, including brand
name recognition, substantially greater than ours as well as other competitive
advantages over us.

                                       40

   Incumbent Local Exchange Carriers. In each of the markets we target, we will
compete principally with the incumbent local exchange carrier serving that
area, such as Pacific Bell and GTE in California. Some incumbent local exchange
carriers, including GTE, are offering long distance services to their local
telephone customers. The regional Bell operating companies, including Pacific
Bell, are actively seeking removal of federal regulatory restrictions that
prevent them from entering the long distance market. Many experts expect the
regional Bell operating companies to be successful in entering the long
distance market in a few states within the next two years and in most states
within a year or two thereafter. We believe the regional Bell operating
companies expect to offset market share losses in their local markets by
capturing a significant percentage of the long distance market, especially in
the residential segment where the regional Bell operating companies' strong
regional brand names and extensive advertising campaigns may be very
successful. See "--Regulation."

   As a relatively recent entrant in the integrated telecommunications services
industry, we have not achieved and do not expect to achieve a significant
market share for any of our services. In particular, the regional Bell
operating companies and other local telephone companies have long-standing
relationships with their customers, have financial, technical and marketing
resources substantially greater than ours, have the potential to subsidize
competitive services with revenues from a variety of businesses, have long-
standing relationships with regulatory authorities at the federal and state
levels, and currently benefit from certain existing regulations that favor the
incumbent local exchange carriers over us in certain respects. While recent
regulatory initiatives, which allow competitive local exchange carriers such as
ourselves to interconnect with incumbent local exchange carrier facilities,
provide us with increased business opportunities, such interconnection
opportunities have been, and likely will continue to be, accompanied by
increased pricing flexibility for and relaxation of regulatory oversight of the
incumbent local exchange carriers.

   The FCC recently adopted an order that provides for increased incumbent
local exchange carrier pricing flexibility and deregulation of some access
services and provides a framework for increased pricing flexibility of other
services based on a showing by the incumbent local exchange carrier that there
is facilities-based competition in specified geographic areas. After meeting
these requirements, incumbent local exchange carriers will be allowed to offer
discounts to large customers through contract arrangements. The order also
permits incumbent local exchange carriers to offer new access services by
filing tariffs without prior approval and dispensing with the requirement for
them to provide cost supports for their pricing. The FCC also issued a Notice
of Proposed Rulemaking that would permit added pricing flexibility for local
exchange carriers for additional services conditioned on to be determined
competitive criteria and initiates an inquiry into whether competitive local
exchange carrier access rates should be regulated. Implementation of the FCC's
order could have a material adverse effect on us. As purchasers of access
services, we may see increased competition for those services which could lower
prices we have to pay for such services.

   Competitive Access Carriers/Competitive Local Exchange Carriers/Other Market
Entrants. We also face, and expect to continue to face, competition from other
current and potential market entrants, including long distance carriers seeking
to enter, reenter or expand entry into the local exchange market such as AT&T,
MCI Worldcom, and Sprint, and from other competitive local exchange carriers,
out-of-region incumbent local exchange carriers, resellers of local exchange
services, cable television companies, electric utilities, microwave carriers,
wireless telephone system operators and private networks built by large end
users. In addition, a continuing trend toward mergers, acquisitions and
strategic alliances in the telecommunications industry could also increase the
level of competition we face. Consolidation is also occurring in the incumbent
local exchange carrier industry, such as the proposed plans for mergers between
SBC and Ameritech, and between Bell Atlantic and GTE. These types of
consolidations and alliances could put us at a competitive disadvantage.

   The Telecommunications Act of 1996 imposes certain regulatory requirements
on all local exchange carriers, including competitors such as ourselves, while
granting the FCC expanded authority to reduce the level of regulation
applicable to any or all telecommunications carriers, including incumbent local
exchange carriers. The manner in which these provisions of the
Telecommunications Act of 1996 are implemented and enforced could have a
material adverse effect on our ability to successfully compete against
incumbent local exchange carriers and other telecommunications service
providers.

                                       41
<PAGE>

   The changes in the Telecommunications Act of 1996 radically altered the
market opportunity for traditional competitive local exchange carriers. Because
many existing competitive local exchange carriers initially entered the market
providing dedicated access in the pre-1996 era, they had to build a fiber
infrastructure before offering services. Switches were added by most
competitive local exchange carriers since 1996 to take advantage of the opening
of the local market. With the Telecommunications Act of 1996 requiring
unbundling of the incumbent local exchange carrier networks, competitive local
exchange carriers are now able to enter the market more rapidly by installing
switches and leasing fiber transport capacity until traffic volume justifies
building facilities. New competitive local exchange carriers will not have to
replicate existing facilities and can be more opportunistic in designing and
implementing networks.

   Competition for Provision of Long Distance Services. The long distance
telecommunications industry has numerous entities competing for the same
customers and a high average churn rate, as customers frequently change long
distance providers in response to the offering of lower rates or promotional
incentives by competitors. Prices in the long distance market have declined
significantly in recent years and are expected to continue to decline.

   Internet Service Providers. The competition for Internet service provider
customers in the telecommunications industry is high and we expect that
competition will intensify. In addition, alternative competing technologies
regarding this service may emerge. Our competitors in this market include other
telecommunications companies, including integrated online services providers
with their own communications networks. Many of these competitors have greater
financial, technological, marketing, personnel and other resources than ours.

   Competition from International Telecommunications Providers. Under the
recent World Trade Organization agreement on basic telecommunications services,
the United States and 68 other members of the World Trade Organization
committed themselves to opening their respective telecommunications markets to
foreign ownership and/or to adopting regulatory measures to protect competitors
against anticompetitive behavior by dominant telecommunications companies,
effective in some cases as early as January 1998. Although we believe that the
World Trade Organization agreement could provide us with significant
opportunities to compete in markets that were not previously accessible and to
provide more reliable services at lower costs than we could have provided prior
to implementation of the World Trade Organization agreement, it could also
provide similar opportunities to our competitors. There can be no assurance
that the pro-competitive effects of the World Trade Organization agreement will
not have a material adverse effect on our business, financial condition and
results of operations or that members of the World Trade Organization will
implement the terms of the World Trade Organization agreement.

Regulation

   Our telecommunications services business is subject to varying degrees of
federal, state and local regulation.

 Federal Regulation

   The FCC regulates interstate and international telecommunications services.
We provide service on a common carrier basis. The FCC imposes certain
regulations on common carriers such as the regional Bell operating companies
that have some degree of market power. The FCC imposes less regulation on
common carriers without market power including, to date, competitive local
exchange carriers. Among other obligations, common carriers are generally
subject to nondiscrimination and tariff filing requirements, as well as certain
service reporting requirements. The FCC also requires common carriers to
receive an authorization to construct and operate telecommunications
facilities, and to provide or resell telecommunications services, between the
United States and international points.

   In August 1996, the FCC released an interconnection decision establishing
rules implementing the Telecommunications Act of 1996 requirements that
incumbent local exchange carriers negotiate interconnection

                                       42
<PAGE>

agreements and providing guidelines for review of such agreements by state
public utilities commissions. On July 18, 1997, the Eighth Circuit vacated
certain portions of the interconnection decision, including provisions
establishing a pricing methodology and a procedure permitting new entrants to
pick and choose among various provisions of existing interconnection agreements
between incumbent local exchange carriers and their competitors. On October 14,
1997, the Eighth Circuit issued a decision vacating additional FCC rules
affecting the use of combinations of an incumbent local exchange carrier's
unbundled network elements. On January 25, 1999, the Supreme Court reversed
most aspects of the Eighth Circuit's holdings with respect to FCC jurisdiction
and, among other things, declared that the FCC has general authority under the
Telecommunications Act of 1996 to promulgate regulations governing local
interconnection pricing, including regulations governing reciprocal
compensation. The Supreme Court also found that the FCC had the authority to
promulgate a pick and choose rule, and upheld most of the FCC's rules governing
access to unbundled network elements. The Court, however, remanded to the FCC
its designation of unbundled network elements based on the FCC's use of an
improper standard to determine whether an unbundled element must be made
available. On September 15, 1999, the FCC adopted a decision in response to the
Supreme Court's remand. While the text of the decision has not been released,
information provided by the FCC indicates that the FCC concluded that seven of
eight previously identified network elements must be unbundled. The FCC deleted
access to operator and directory assistance service and determined that in the
most dense areas of the top 50 metropolitan areas in certain circumstances
local switching need not be unbundled.

   The Eighth Circuit decisions and their recent reversal by the Supreme Court
perpetuate continuing uncertainty about the rules governing the pricing, terms
and conditions of interconnection agreements. The Supreme Court's action in
particular may require or trigger the renegotiation of existing agreements.
Although state public utilities commissions have continued to conduct
arbitrations, and to implement and enforce interconnection agreements during
the pendency of the Eighth Circuit proceedings, the Supreme Court's recent
ruling and further proceedings on remand at the Eighth Circuit or the FCC may
affect the scope of state commissions' authority to conduct such proceedings or
to implement or enforce interconnection agreements. They could also result in
new or additional rules being promulgated by the FCC. Given the general
uncertainty surrounding the effect of the Eighth Circuit decisions and the
recent decision of the Supreme Court reversing them, there can be no assurance
that we will be able to continue to obtain or enforce interconnection terms
that are acceptable to us or that are consistent with our business plans.

   The Telecommunications Act of 1996 is intended to increase competition. The
act opens the local services market by requiring incumbent local exchange
carriers to permit interconnection to their networks and establishing incumbent
local exchange carrier obligations with respect to:

     Reciprocal Compensation. Requires all incumbent local exchange carriers
  and competitive local exchange carriers to complete calls originated by
  competing carriers under reciprocal arrangements at prices based on a
  reasonable approximation of incremental cost or through mutual exchange of
  traffic without explicit payment.

     Resale. Requires all incumbent local exchange carriers and competitive
  local exchange carriers to permit resale of their telecommunications
  services without unreasonable restrictions or conditions. In addition,
  incumbent local exchange carriers are required to offer wholesale versions
  of all retail services to other telecommunications carriers for resale at
  discounted rates, based on the costs avoided by the incumbent local
  exchange carrier in the wholesale offering.

     Interconnection. Requires all incumbent local exchange carriers and
  competitive local exchange carriers to permit their competitors to
  interconnect with their facilities. Requires all incumbent local exchange
  carriers to permit interconnection at any technically feasible point within
  their networks, on nondiscriminatory terms, at prices based on cost, which
  may include a reasonable profit. At the option of the carrier seeking
  interconnection, collocation of the requesting carrier's equipment in the
  incumbent local exchange carriers' premises must be offered, except where
  an incumbent local exchange carrier can demonstrate space limitations or
  other technical impediments to collocation.

                                       43
<PAGE>

     Unbundled Access. Requires all incumbent local exchange carriers to
  provide nondiscriminatory access to unbundled network elements, including
  certain network facilities, equipment, features, functions, and
  capabilities, at any technically feasible point within their networks. Such
  access must be on nondiscriminatory terms, at prices based on cost, which
  may include a reasonable profit.

     Number Portability. Requires all incumbent local exchange carriers and
  competitive local exchange carriers to permit users of telecommunications
  services to retain existing telephone numbers without impairment of
  quality, reliability or convenience when switching from one
  telecommunications carrier to another.

     Dialing Parity. Requires all incumbent local exchange carriers and
  competitive local exchange carriers to provide "1+" equal access to
  competing providers of telephone exchange service and toll service, and to
  provide nondiscriminatory access to telephone numbers, operator services,
  directory assistance, and directory listing, with no unreasonable dialing
  delays.

     Access to Rights-of-Way. Requires all incumbent local exchange carriers
  and competitive local exchange carriers to permit competing carriers access
  to poles, ducts, conduits and rights-of-way at regulated prices.

   Incumbent local exchange carriers are required to negotiate in good faith
with carriers requesting any or all of the above arrangements. If the
negotiating carriers cannot reach agreement within a prescribed time, either
carrier may request arbitration of the disputed issues by the state regulatory
commission. Where an agreement has not been reached, incumbent local exchange
carriers remain subject to interconnection obligations established by the FCC
and state telecommunication regulatory commissions.

   On May 8, 1997, the FCC released an order establishing a significantly
expanded federal universal service subsidy regime. For example, the FCC
established new subsidies for telecommunications and information services
provided to qualifying schools and libraries with an annual cap of $2.3 billion
and for services provided to rural health care providers with an annual cap of
$400.0 million. The FCC also expanded the federal subsidies for local exchange
telephone service provided to low-income consumers. Providers of interstate
telecommunications service, such as ourselves, as well as certain other
entities, must pay for these programs. Our share of these federal subsidy funds
will be based on our share of certain defined telecommunications end-user
revenues. Currently, the FCC is assessing such payments on the basis of a
provider's revenue for the previous year. We are paying approximately $16,000
per month in subsidy payments during the first half of 1999. To offset this
expense, we currently charge our customers a surcharge on all interstate usage,
subject to periodic adjustment. The FCC is currently in the process of revising
its rules for subsidizing service provided to consumers in high cost areas,
which may result in further substantial increases in the overall cost of the
subsidy program. The FCC postponed the projected effective date of this
revision to January 1, 2000. Several parties appealed the May 8th order. Such
appeals were consolidated and transferred to the United States Court of Appeals
for the Fifth Circuit. On July 30, 1999, the Fifth Circuit affirmed most
portions of the May 8th order, but remanded certain aspects of the order to the
FCC to conduct further proceedings. The FCC and a federal-state joint board
also are continuing to examine and revise various aspects of universal service.
We cannot predict the effect that further regulatory or judicial revision of
the universal service regime will have on our business, financial condition or
results of operations.

   The Telecommunications Act of 1996 codifies the incumbent local exchange
carriers' equal access and nondiscrimination obligations and preempts
inconsistent state regulation. The Telecommunications Act of 1996 also contains
special provisions that eliminate the AT&T Antitrust Consent Decree and similar
antitrust restrictions on the regional Bell operating companies restricting the
regional Bell operating companies from providing long distance services and
engaging in telecommunications equipment manufacturing. The Telecommunications
Act of 1996 permitted the regional Bell operating companies to enter the out-
of-region long distance market immediately upon its enactment. Further,
provisions of the Telecommunications Act of 1996 permit a regional Bell
operating company to enter the long distance market in its traditional service
area if it satisfies several procedural and substantive requirements in those
states in which it seeks long distance

                                       44
<PAGE>

relief. These requirements include obtaining FCC approval upon a showing that
the regional Bell operating company has entered into interconnection agreements
or, under some circumstances, has offered to do so. The interconnection
agreements must satisfy a 14-point checklist of competitive requirements and
the FCC must be satisfied that the regional Bell operating companies' entry
into long distance markets is in the public interest. To date, several
petitions by regional Bell operating companies for such entry have been denied
by the FCC and none has been granted.

   Under the Telecommunications Act of 1996, any entity, including cable
television companies and electric and gas utilities, may enter any
telecommunications market, subject to reasonable state regulation of safety,
quality and consumer protection. Because implementation of the
Telecommunications Act of 1996 is subject to numerous federal and state policy
rulemaking proceedings and judicial review there is still uncertainty as to
what impact such legislation will have on us, but it is likely to encourage
additional competitive entry in markets we serve.

   In accordance with authority granted by the FCC, we resell the international
telecommunications services of other common carriers between the United States
and international points. In connection with such authority, we have filed
tariffs with the FCC stating the rates, terms and conditions for our
international services.

   With respect to our domestic service offerings, we have filed tariffs with
the FCC stating the rates, terms and conditions for our interstate services.
Our tariffs are generally not subject to pre-effective review by the FCC, and
can be amended on one day's notice. Our interstate services are provided in
competition with interexchange carriers and, with respect to access services,
the incumbent local exchange carriers.

   In October 1996, the FCC adopted an order eliminating the requirement that
non-dominant interstate carriers such as ourselves maintain tariffs on file
with the FCC for domestic interstate services. This order applies to all non-
dominant interstate carriers, including AT&T. The order does not apply to the
switched and special access services of the regional Bell operating companies
or other local exchange providers. On February 13, 1997, the United States
Court of Appeals for the District of Columbia Circuit stayed the implementation
of the FCC order pending its review of the order on the merits. Currently, that
temporary stay remains in effect. If the stay is lifted and the FCC order
becomes effective, telecommunications carriers such as ourselves will no longer
be able to rely on the filing of tariffs with the FCC as a means of providing
notice to customers of prices, terms and conditions on which they offer their
interstate services. In June 1997, the FCC issued another order which allows
non-dominant carriers, such as ourselves, to offer interstate access services
without the filing of tariffs. The obligation to provide non-discriminatory,
just and reasonable prices remains unchanged under the Communications Act of
1934. While tariffs provided a means of providing notice of prices, terms and
conditions, we intend to rely primarily on our sales force and direct marketing
to provide such information to our customers.

   To the extent we provide interexchange telecommunications service, we are
required to pay access charges to incumbent local exchange carriers and other
competitive local exchange carriers when we use the facilities of those
companies to originate or terminate interexchange calls. Also, as a competitive
local exchange carrier, we provide access services to other interexchange
service providers. The interstate access charges of incumbent local exchange
carriers are subject to extensive regulation by the FCC, while those of
competitive local exchange carriers are subject to a lesser degree of FCC
regulation but remain subject to the requirement that all charges be just,
reasonable, and not unreasonably discriminatory. In two orders released on
December 24, 1996, and May 16, 1997, the FCC made major changes to the
interstate access charge structure. In the December 24th order, the FCC removed
restrictions on incumbent local exchange carriers' ability to lower access
prices and relaxed the regulation of new switched access services in those
markets where there are other providers of access services. If this increased
pricing flexibility is not effectively monitored by federal regulators, it
could have a material adverse effect on our ability to compete in providing
interstate access services. The May 16th order substantially increased the
costs that price cap incumbent local exchange carriers subject to the FCC's
price cap rules, recover through monthly, non-traffic-sensitive access charges
and substantially decreased the costs that price cap incumbent local exchange
carriers recover through traffic-sensitive access charges. In the

                                       45
<PAGE>

May 16th order, which was upheld on appeal by the United States Court of
Appeals for the Eighth Circuit, the FCC also announced its plan to bring
interstate access rate levels more in line with costs. On August 5, 1999, the
FCC adopted an order granting price cap local exchange carriers additional
pricing flexibility, implementing certain access charge reforms, and seeking
comment on others. The order provides certain immediate regulatory relief to
price cap carriers and sets a framework of "triggers" to provide these
companies with greater flexibility to set interstate access rates as
competition increases. The order also initiated rulemaking to determine whether
the FCC should regulate competitive local exchange carriers access charges. The
manner in which the FCC continues to implement its approach to lowering access
charge levels and a decision to regulate competitive local exchange carrier
access rates could have a material effect on our ability to compete in
providing interstate access services.

   On February 26, 1999, the FCC issued a declaratory ruling on the issue of
inter-carrier compensation for calls bound to Internet service providers. The
FCC ruled that the calls are jurisdictionally mixed, but largely interstate
calls. The FCC, however, determined that this issue did not resolve the
question of whether inter-carrier reciprocal compensation is owed for such
calls under existing interconnection agreements. The FCC noted a number of
factors that would allow the state public utilities commissions to continue to
require the payment of reciprocal compensation. Since the issuance of the FCC
decision, twenty-two states have issued decisions either initially or on
reconsideration of existing decisions. In twenty states, the commission
determined compensation is owed. In Massachusetts, however, the commission
vacated its earlier decision because, in its view, its decision was based
solely on a ground rejected by the FCC and in Missouri the commission
determined that the parties payments would be subject to a reconciliation once
the FCC determines the issue of the amount of compensation owed. Until then,
compensation should be tracked but it does not have to be paid. New Jersey and
South Carolina are the only states to find reciprocal compensation does not
apply. We cannot predict the impact of the FCC's ruling on existing state
decisions, the outcome of pending appeals or future litigation on this issue.

 State Regulation

   State regulatory agencies have regulatory jurisdiction when Pac-West
facilities and services are used to provide intrastate services. A significant
portion of our current traffic is classified as intrastate and therefore
subject to state regulation. To provide intrastate services, we generally must
obtain a certificate of public convenience and necessity from the state
regulatory agency and comply with state requirements for telecommunications
utilities, including state tariffing requirements. We have obtained such
certificates to provide local exchange and intrastate toll service in
California, Nevada, Washington, Oregon, Arizona and Colorado, an application is
pending in Texas, and we intend to file applications for such authority in the
near future for Idaho, Utah and New Mexico. There can be no assurance that such
state authorizations will be granted. Most states in which we operate or
propose to operate also requires us to seek approval for any transfers of
control.

   In addition, the implementation of the Telecommunications Act of 1996 is
subject to numerous state rulemaking proceedings on these issues, it is
currently difficult to predict how quickly full competition for local services,
including local dial tone, will be introduced. Furthermore, the
Telecommunications Act of 1996 provides that state public utilities commissions
have significant roles in determining the content of interconnection
agreements, including the responsibility to conduct the mandatory arbitration
proceedings called for by the Telecommunications Act of 1996. The actions of
the state public utilities commissions are subject to the Telecommunications
Act of 1996 and, in several respects, the FCC's interpretations thereof. For
example, the FCC has determined that the state public utilities commissions
will continue to determine whether reciprocal compensation will be included in
arbitrated interconnection agreements at least until the FCC adopts a federal
rule.

   On October 22, 1998, the California Public Utilities Commission issued a
decision holding that local telephone calls placed to Internet service
providers are local calls entitled to reciprocal compensation. On November 30,
1998, Pacific Bell and GTE filed applications for rehearing of the October 22,
1998 decision, which were denied on July 22, 1999. On August 25, 1999, we,
along with the commissioners of the California Public

                                       46
<PAGE>

Utilities Commission and others, were named as a defendant in an action filed
by GTE California. The action challenges the legality of the California Public
Utilities Commission's decisions regarding reciprocal compensation as discussed
above. We intend to seek dismissal of the action and otherwise contest the
claims of GTE California.

   The California Public Utilities Commission may commence a separate generic
proceeding to develop its prospective policy regarding reciprocal compensation.
We cannot predict the outcome of the California Public Utilities Commission or
GTE proceedings, future appeals or additional pending cases involving related
issues, or of the applicability of such proceedings to our interconnection
agreement with Pacific Bell or GTE. As a result, no assurance can be given that
we will collect the reciprocal compensation previously withheld by GTE or
whether we will be entitled to reciprocal compensation for these types of calls
in the future. Internet service providers currently form a significant part of
our customer base in California and adverse decisions in these proceedings
could limit our ability to serve this group of customers profitably and have a
material adverse effect on us.

   We expect that reciprocal compensation will continue to represent a
significant portion of our revenues in the future although we expect that the
per minute reciprocal compensation rate may decline significantly under new
interconnection agreements. We are currently in the process of renegotiating
our interconnection agreement and the terms of our reciprocal compensation
arrangements with GTE, and no assurance can be given concerning the outcome of
these negotiations or any arbitration under Section 252 which may occur in the
absence of successful negotiations.

   On November 16, 1998, Pacific Bell filed a Petition for Arbitration of an
interconnection agreement in accordance with Section 252(b) of the
Telecommunications Act of 1996. This agreement would replace the
interconnection agreement which was executed in 1996.

   On June 24, 1999, the California Public Utilities Commission adopted a
decision (D.99-06-088) which adopted the terms of the interconnection agreement
between Pac-West and Pacific Bell resulting from the arbitration process
commenced by the petition. The decision provides that until such time as the
October 1998 decision regarding reciprocal compensation is modified, reciprocal
compensation is payable by Pacific Bell for calls to Internet service provider
customers of Pac-West. The decision also adopts per minute rate levels for
reciprocal compensation based on Pacific Bell's approved costs, and these rate
levels are substantially lower than the rates under the 1996 interconnection
agreement. The parties were ordered to sign an interconnection agreement
incorporating these and other results of the arbitration process, and the new
interconnection agreement became effective on June 29, 1999. Pacific Bell has
requested a rehearing of this matter and on October 6, 1999, filed an appeal in
federal district court in San Francisco with respect to this decision although
they have paid the full amount of our billings for calls after the effective
date of the new agreement.

 Local Regulation

   Our networks are subject to numerous local regulations such as building
codes and licensing requirements. Such regulations vary on a city by city and
county by county basis. To the extent we decide in the future to install our
own fiber optic transmission facilities, we will need to obtain rights-of-way
over private and publicly owned land and pole attachment authorizations. There
can be no assurance that such rights-of-way or authorizations will be available
to us on economically reasonable or advantageous terms. We could also be
subject to unexpected franchise requirements and could be required to pay
license or franchise fees based on a percentage of gross revenues or some other
formula.

Regulatory Proceedings

 Litigation

   On October 8, 1997, Pacific Bell filed a complaint against us in the San
Francisco County Superior Court seeking a declaratory ruling that the
interconnection agreement between it and ourselves does not require it to pay
reciprocal compensation for calls that its end users make to our Internet
service provider customers. Pacific Bell argued that such calls to Internet
service providers are not local calls within the meaning of the agreement

                                       47
<PAGE>

even though they are dialed and billed as local calls. In addition to the
declaratory ruling, Pacific Bell sought an accounting and restitution by Pac-
West of all payments Pacific Bell made to us under that agreement for calls
which we completed to Internet service providers. We filed a demurrer to the
complaint, seeking a stay of any further action by the court on the basis that
the California Public Utilities Commission has primary jurisdiction over the
complaint. The court granted our demurrer in part on October 23, 1997, staying
Pacific Bell's action pending California Public Utilities Commission review of
issues in Pacific Bell's complaint.

   On October 1, 1999, Pacific Bell filed with the San Francisco County
Superior Court a motion to dismiss their complaint, and we expect the court to
grant their motion in due course.

 Jurisdiction over and Compensation for Internet Service Provider Traffic

   We derive a substantial portion of our revenue from incumbent local exchange
carriers in the form of reciprocal compensation payments. For the years ended
December 31, 1997 and 1998 and the six month period ended June 30, 1999,
reciprocal compensation payments accounted for approximately 37.4%, 37.1% and
41.8%, respectively, of our revenue. We expect that reciprocal compensation
will continue to represent a significant portion of our revenue for the
foreseeable future. Two incumbent local exchange carriers with which we have
interconnection agreements, Pacific Bell and GTE, refused to pay that portion
of reciprocal compensation due under their prior agreement that they estimated
was the result of terminating calls to Internet service providers. These
incumbent local exchange carriers contend that such calls are not local calls
within the meaning of their respective interconnection agreements and claim
that reciprocal compensation is therefore not payable. The total reciprocal
compensation withheld by these incumbent local exchange carriers and not
included in revenue was $3.8 million, $32.6 million and $28.4 million for the
years ended December 31, 1997 and 1998 and for the six month period ended June
30, 1999, respectively. See "Risk Factors--A failure to establish
interconnection agreements on favorable terms would adversely affect our
business" and "--We may not be entitled to receive reciprocal compensation for
calls to Internet service providers."

   On November 21, 1997, we filed a complaint against Pacific Bell requesting,
among other things, that the California Public Utilities Commission order that
calls to Internet service providers are local calls and, more specifically,
that the agreement with Pacific Bell requires it to compensate us for
completing those calls. In March 1998, Pac-West and Pacific Bell filed cross-
motions by stipulation for summary judgment on all issues pending in this
proceeding.

   On September 9, 1999, Pac-West entered into a settlement agreement with
Pacific Bell regarding our claims for unpaid reciprocal compensation under our
prior interconnection agreement. Under the terms of the settlement agreement,
Pacific Bell agreed to pay $20.0 million to Pac-West and $20.0 million to
certain stockholders of Pac-West as of the date of the recapitalization in
settlement of those claims. As a result of these payments, the terms of our
September 1998 recapitalization requiring additional distributions to certain
of our shareholders have been satisfied. As of September 30, 1999, the total
amount of reciprocal compensation, including late fees, which remains withheld
by incumbent local exchange carriers is approximately $7.2 million. We cannot
predict the ultimate outcome of the California Public Utilities Commission
proceeding, future appeals or additional pending cases. Therefore, we cannot
assure you that we will collect the withheld compensation from GTE or that we
will have the right to compensation for these types of calls in the future. If
the California Public Utilities Commission acts contrary to our position, the
ability to serve our customer base could be severely limited since a large part
of that base consists of Internet service providers. If the California Public
Utilities Commission acts contrary to our position, and it is determined that
the compensation associated with past Internet service provider traffic is
greater than the amount already withheld, we could be required to reimburse the
incumbent local exchange carriers the difference between these two amounts.

   On October 22, 1998, the California Public Utilities Commission issued a
decision holding that calls placed to Internet service providers are local
calls and are subject to reciprocal compensation. On November 30, 1998,

                                       48

Pacific Bell and GTE filed applications for rehearing, which was denied on July
22, 1999. On August 25, 1999, we, along with the commissioners of the
California Public Utilities Commission and others, were named as a defendant in
an action filed by GTE California. The action challenges the legality of the
California Public Utilities Commission's decisions regarding reciprocal
compensation as discussed above. We intend to seek dismissal of the action or
otherwise contest the claims of GTE California. We cannot predict the outcome
of the California Public Utilities Commission or GTE proceedings, future
appeals or additional pending cases. Therefore, we cannot assure you that we
will collect the withheld compensation from GTE or that we will have the right
to compensation for these types of calls in the future. If the California
Public Utilities Commission does act contrary to our position, our ability to
serve our customer base could be severely limited since a large part of that
base consists of Internet service providers. If the California Public Utilities
Commission acts contrary to our position and the compensation associated with
past Internet service provider traffic is greater than the amount already
withheld, we could be required to reimburse the incumbent local exchange
carriers for the difference between these two amounts.

   On November 18, 1998, Pacific Bell filed a complaint against us at the
California Public Utilities Commission seeking unspecified compensation under
the interconnection agreement with us. This complaint, which was amended on
March 12, 1999, argues that many of the calls to our Internet service provider
customers are toll-free interexchange calls for which Pacific Bell is entitled
to compensation for providing switched access. Pacific Bell believes that a
call placed from a dialing party in one rate center to a number assigned to the
same rate center is potentially a toll call if such a call is routed for
completion in a second rate center. Because the dialing party is sometimes not
charged for this call, Pacific Bell believes these calls to be toll-free calls
for which Pacific Bell is entitled to compensation under the agreement. We
presently claim reciprocal compensation based on these calls.

   On February 26, 1999, the FCC issued a declaratory ruling on the issue of
inter-carrier compensation for calls bound to Internet service providers. The
FCC ruled that the calls are jurisdictionally mostly interstate calls. The FCC,
however, determined that this issue did not resolve the question of whether
inter-carrier reciprocal compensation is owed for such calls under existing
interconnection agreements. The FCC noted a number of factors that would allow
the state public utilities commissions to require the payment of reciprocal
compensation. Since the issuance of the FCC decision, twenty-two states have
issued decisions either initially or on reconsideration of existing decisions.
In twenty states, the relevant state commission determined compensation is
owed. In Massachusetts, however, the state commission vacated its earlier
decision because, in its view, its decision was based solely on a ground
rejected by the FCC and in Missouri the state commission determined that the
parties would be subject to a reconciliation once the FCC determines the issue
of the amount of compensation owed. Until then, compensation should be tracked
but it does not have to be paid. New Jersey and South Carolina the only state
to find reciprocal compensation does not apply. Several of these cases are
being appealed. So far, U.S. District courts in the states of Texas,
Washington, Oregon, Michigan, Alabama, Oklahoma and Illinois have upheld state
commission decisions and no court has reversed such a decision. Recently the
7th Circuit Court of Appeals upheld the decision of the Illinois Commerce
Commission requiring the payment of reciprocal compensation for Internet
service provider-bound calls. The U.S. District Court in Wisconsin and Arkansas
dismissed appeals on the grounds that the state commissions were not subject to
being sued in federal court. We cannot predict the impact of the FCC's ruling
on existing state decisions, the outcome of pending appeals or future
litigation on this issue. However, our ability to serve our customer base could
be severely limited since a large part of that base consists of Internet
service providers. If the FCC's decision results in action being taken that is
contrary to our position, and it is determined that the compensation associated
with past Internet service provider traffic is greater than the amount already
withheld, we could be required to reimburse the incumbent local exchange
carriers for the difference between these two amounts.

 Rating and Routing of Calls

   By California Public Utilities Commission Decision No. 97-12-094 in Case No.
96-10-018, which was brought by Pac-West against two small rural incumbent
local exchange carriers, Volcano Telephone Company

                                       49
<PAGE>

and Evans Telephone Company, the California Public Utilities Commission found
that Pac-West's method of providing foreign exchange service did not violate
any existing law or policy and that Volcano and Evans were required to properly
deliver calls to Pac-West. However, the California Public Utilities Commission
also determined that it should examine our method of service from a general
policy standpoint in another proceeding. Although the outcome of the subsequent
proceeding could affect our future provision of foreign exchange like services,
the California Public Utilities Commission held that any order adverse to us
would be applied only on a prospective basis and would not affect any contracts
for services executed prior to a final decision. On July 22, 1998, the
California Public Utilities Commission issued a ruling soliciting comments on
the rating and routing of telephone calls between rate centers. Specifically,
the California Public Utilities Commission inquired whether a carrier should be
allowed to provide customers with local telephone numbers for rate centers in
which the customers are not located and where a carrier has no physical
facilities and, if so, how inter-carrier compensation should be accomplished
for calls to such customers. Comments were filed in August and September 1998.
We often provide service to our Internet service provider customers using this
method. A prohibition on this service would impair our ability to provide
service to our customers. The new interconnection agreement described above
which results from the arbitration process is subject to the outcome of this
proceeding. We presently claim reciprocal compensation based on these calls. A
California Public Utilities Commission decision holding that such calls are not
entitled to reciprocal compensation could result in a substantial loss of
revenue to us. On September 3, 1999, the California Public Utilities Commission
released a decision in this proceeding finding that carriers can provide
customers with local telephone numbers for rate centers in which the customer
is not located and where a carrier has no physical facilities. The decision
defers the resolution of intercarrier compensation issues in such circumstances
to further evidentiary proceedings. While the ultimate results of this
proceeding are unknown, we expect that we will not be prohibited from providing
service using this method although the reciprocal compensation rate may be
lessened. See "Risk Factors--A failure to establish interconnection agreements
on favorable terms would adversely affect our business," "--We may not be
entitled to receive reciprocal compensation for calls to Internet service
providers" and "--We may not be able to obtain or retain our key Internet
service provider customers, which account for a significant portion of our
revenues."

 Interconnection Agreements

   We are currently in the process of renegotiating our interconnection
agreement which governs the terms of our reciprocal compensation arrangements
with GTE. We cannot give any assurances concerning the outcome of these
negotiations or any arbitration that may follow unsuccessful negotiations.

   On November 16, 1998, Pacific Bell filed a petition for Arbitration of an
interconnection agreement in accordance with Section 252(b) of the
Telecommunications Act of 1996. In its petition, Pacific Bell requested
arbitration on three main issues:

   (1) the jurisdiction of calls placed to Internet service providers;

   (2) reciprocal compensation rates; and

   (3) term of the agreement.

   On June 24, 1999, the California Public Utilities Commission determined that
reciprocal compensation would be payable for Internet service provider calls
under our new interconnection agreement with Pacific Bell, which became
effective on June 29, 1999. Pacific Bell requested a rehearing of this
decision, although Pacific Bell paid the full amount of our billings for calls
since the effective date of the new agreement. On October 6, 1999, Pacific Bell
filed an appeal in federal district court in San Francisco with respect to the
California Public Utilities Commission decision. This decision does not address
reciprocal compensation under the prior agreement. A determination by the
California Public Utilities Commission or the federal court that determines
that such calls are not entitled to reciprocal compensation could result in a
significant loss of revenue to us.

   On October 12, 1998, we filed at the Public Utilities Commission of Nevada a
petition for arbitration of an interconnection agreement with Nevada Bell in
accordance with Section 252(b) of the Telecommunications Act

                                       50
<PAGE>

of 1996. The issues in this arbitration are whether reciprocal compensation is
payable for calls placed to Internet service providers and whether reciprocal
compensation is payable for a local-rated call placed by a dialing party in one
local calling area that is routed to a second local calling area for
completion. On April 8, 1999, the Public Utilities Commission of Nevada held
that calls placed to Internet service providers are subject to reciprocal
compensation in the same manner as other calls, but held that, under current
Nevada regulatory policy, calls routed from one local calling area to another
local calling area for completion should not be deemed local calls. Due to the
geographic centralization of Nevada populations within large local calling
areas, we do not believe that Public Utilities Commission of Nevada's ruling on
the classification of local calls will have a material effect on our planned
operations in Nevada. On September 2, 1999, Nevada Bell appealed the decision
of the Public Utilities Commission of Nevada to the U.S. District Court in
Nevada. We intend to defend the validity of the decision before the court.

   On February 2, 1999, we filed at the California Public Utilities Commission
a petition for arbitration of an interconnection agreement with Citizens
Telecommunications Company of California, Inc., in accordance with Section
252(b) of the Telecommunications Act of 1996. The issues in this arbitration
are whether reciprocal compensation is payable for calls placed to Internet
service providers and what compensation arrangement should apply when calls are
exchanged through indirect interconnection over the facilities of a third party
carrier. A California Public Utilities Commission holding contrary to our
position could materially adversely affect our ability to economically serve
customers in Citizens Telecommunications Company of California, Inc.'s service
area.

   We are not party to any other pending legal or regulatory proceedings that
we believe would, individually or in the aggregate, have a material adverse
effect on our financial condition or results of operations.

   For additional information regarding regulatory matters, see "Risk Factors--
We may not be entitled to receive reciprocal compensation for calls to Internet
service providers."

Employees

   As of June 30, 1999, we had 187 full time employees. We believe that our
future success will depend on our continued ability to attract and retain
highly skilled and qualified employees. None of our employees are currently
represented by a collective bargaining agreement. We believe that we enjoy good
relationships with our employees.

Facilities

   We are headquartered in Stockton, California and lease offices and space in
a number of locations primarily for sales offices and network equipment
installations. As of June 30, 1999, we had 17 premise leases. The table below
lists our material facilities:

</TABLE>

   Since June 30, 1999, we entered into a lease for an additional 6,062 square
feet of space in Los Angeles, California. The lease has an initial expiration
date of September 30, 2006 and contains two five-year renewal options. We are
also in the process of entering into a lease in Seattle, Washington to
establish a new switching facility which we expect to be operational by the end
of 1999. This lease will be for 16,851 usable square feet, have an initial term
of 10 years, and contain two five-year renewal options.

                                       51

   We believe that our leased facilities are adequate to meet our current needs
in the markets in which we currently operate. Additional facilities will be
required as our business in existing markets grows and we expand into new
markets. Each of our material leases is extendable at our option. Our Stockton,
California lease is extendable for five two-year periods, and each of our
Oakland, Los Angeles and Las Vegas leases are extendable for two five-year
periods.

   All members of the board of directors set forth in this prospectus have been
elected in accordance with a shareholders agreement that was entered into in
connection with our recapitalization in September 1998. There are no family
relationships between any of our directors or executive officers. Our executive
officers are elected by and serve at the discretion of the board of directors.
See "Certain Relationships and Related Transactions--Shareholders Agreement."

Classes of the Board

   Following the closing of this offering, our Board of Directors will be
divided into three classes of directors, with each class serving staggered
three-year terms. As a result, approximately one-third of our Board of
Directors will be elected each year. Within ten days of the consummation of
this offering, the sitting directors will select by either a random selection
process or by mutual agreement to divide themselves into three groups. See
"Description of Capital Stock--Certain Anti-Takeover, Limited Liability and
Indemnification Provisions."

Committees of the Board of Directors

director in connection with attending board and committee meetings.

Executive Compensation

   The following table summarizes the compensation we paid to our named
executive officers, consisting of our chief executive officer and four most
highly compensated executive officers for the fiscal year ended December 31,
1998. None of the perquisites and other benefits paid to each named executive
officer exceeded the lesser of $50,000 or 10% of the total annual salary and
bonus received by that officer. "All Other Compensation" reflects matching
contributions we made under our 401(k) plan on behalf of such officer. The
amount listed under "All Other Compensation" for Mr. La Rue includes $2,539 of
long-term disability insurance premiums we paid on behalf of Mr. La Rue and
100% dental reimbursements in the amount of $1,015. Mr. Griffin's salary is
from September 16, 1998, when he became our employee. Prior to that time but in
that same year, Mr. Griffin received additional compensation from us in the
total amount of $203,000 under a consulting agreement. See "Certain
Relationships and Related Transactions--Consulting Agreement."

Stock Incentive Plan

   We have established the Pac-West Telecomm, Inc. 1999 Stock Incentive Plan,
which authorizes the granting of stock options, including restricted stock,
SARS, dividend equivalent rights, performance units, performance shares or
other similar rights or benefits to our or our subsidiaries' current or future
employees, directors, consultants, advisors. Under the 1999 Stock Incentive
Plan, the board of directors is authorized to issue options to purchase shares
of common stock in such quantity, at such exercise prices, on such terms and
subject to such conditions as established by the board. An aggregate of
3,150,000 shares of common stock have been reserved for option grants under the
1999 Stock Incentive Plan and the employment agreements of Messrs. Griffin and
Bryson, subject to adjustment upon the occurrence of certain events to prevent
any dilution or expansion of the rights of participants that might otherwise
result from the occurrence of such events. For the six month period ended June
30, 1999, options to purchase 469,000 shares were granted under the Pac-West
1999 Stock Incentive Plan to Messrs. John K. La Rue, Dennis V. Meyer, Jason R.
Mills and Jeff M. Webster. As of June 30, 1999, we had granted options
outstanding with respect to 1,428,700 shares of common stock, including those
granted under the employment agreements. No options have been exercised through
June 30, 1999.

   The amounts shown for realizable potential value are calculated assuming
that the market value of the common stock was equal to the exercise price per
share as of the date of grant of the options. This value is the approximate
price per share at which shares of the common stock would have been sold in
private transactions on or about the date on which the options were granted.
The dollar amounts under these columns assume a compounded annual market price
increase for the underlying shares of the common stock from the date of grant
to the end of the option term of 5% and 10%. This format is prescribed by the
SEC and is not intended to forecast future appreciation of shares of the common
stock. The actual value, if any, a named officer may realize will depend on the
excess of the market price for shares of the common stock on the date the
option is exercised over the exercise price. Accordingly, there is no assurance
that the value realized by a named officer will be at or near the value
estimated above.

Qualified 401(k) and Profit Sharing Plan

   We maintain a tax-qualified 401(k) plan. Employees who are 18 years of age
may elect to participate in the plan after completing six months of service
with us. We match 50% of employee contributions up to 6% of compensation
deferred. Our matching contributions vest at a rate 20% per year starting with
the employee's second year of service. Although we have not historically done
so, we may also make discretionary profit-sharing contributions to all
employees who satisfy plan participation requirements.

Pension Plans

   We do not maintain a pension plan.

Gregory Joksch..................... September 11, 1998 2 years  $110,000    25%
</TABLE>

The employment agreements also provide for participation in all benefit plans
made available to Pac-West executives.

   Each of the employment agreements may be terminated earlier by us or the
respective executive under certain conditions and Mr. Meyer's employment
agreement is automatically extended for successive one-year periods unless
terminated by either party upon 60 days notice.

   In connection with their respective employment agreements, Mr. Griffin
purchased 525,000 shares of common stock for an aggregate purchase price of
$250,000 and Mr. Bryson purchased 87,458 shares of common stock for an
aggregate purchase price of $41,667. In each case, the executives purchased
said shares through a combination of cash and promissory notes, the payments of
which notes were secured by pledge agreements pledging all of stock so
purchased. We have a right to repurchase such shares in the event of the
termination of such executive's employment with us for any reason. In addition,
their respective employment agreements granted to Mr. Griffin and Mr. Bryson
options to purchase 350,000 shares and 218,750 shares, respectively, of common
stock at a purchase price of $0.48 per share.

   Upon termination by us without cause, as defined in the respective
employment agreement, that executive will be entitled to receive severance
payments which, subject to certain conditions, equal:

  . in the case of Mr. La Rue, base salary for the remainder of the term of
    employment under the employment agreement plus the one-year period
    thereafter;

  . in the case of Mr. Griffin, base salary for the greater of the remainder
    of the term of employment under the employment agreement or the six-month
    period thereafter;

  . in the case of Mr. Bryson, base salary for one year following termination
    plus our payment of all health insurance premiums with respect to Mr.
    Bryson's continuation coverage rights under the Consolidated Omnibus
    Budget Reconciliation Act of 1985, as amended, or any similar statute or
    regulation then in effect, for a maximum of the one-year period after
    such termination;

  . in the case of Mr. Meyer, base salary for the one-year period after such
    termination; and

  . in the case of Mr. Mills and Mr. Joksch, base salary for the remainder of
    the term of employment under the employment agreement.

   If the employment period is terminated as a result of the executive's
disability, then the executive and/or his estate or beneficiaries, as the case
may be, will be entitled to receive benefits under our employee benefit
programs as in effect on the date of such termination to the extent permitted
under such programs and, in addition, will be entitled to receive:

  (1) an amount equal to that executive's base salary for the one-year period
      after the termination of the employment period; and

                                       58
<PAGE>

  (2) the amount of any annual bonus otherwise payable to the executive for
      the fiscal year in which executive's employment is terminated, except
      that the amount of any such annual bonus otherwise payable will be
      allocated on the basis of the number of days during such fiscal year
      that executive was employed by us.

If the employment period is terminated as a result of the executive's death,
then the executive and/or his estate or beneficiaries, as the case may be, will
be entitled to receive benefits under our employee benefit programs as in
effect on the date of such termination to the extent permitted under such
programs and, in addition, will be entitled to receive the amount of any annual
bonus otherwise payable to the executive for the fiscal year in which the
executive's employment is terminated, except that the amount of any such annual
bonus otherwise payable will be allocated on the basis of the number of days
during such fiscal year that the executive was employed by us. If we terminate
the employment period for cause or if the executive resigns for any reason,
other than a termination without cause under the respective employment
agreement, then the executive will be entitled to receive his base salary
through the date of termination and we will have no further liability
whatsoever to executive.

   Each of the executives have agreed to forfeit any severance obligations
owing to such executives in the event they breach certain noncompetition
provisions. See "Certain Relationships and Related Transactions--Non-
Competition; Non-Solicitation; Confidentiality Agreements."

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Recapitalization

   Our recapitalization was completed on September 16, 1998 in accordance with
the merger agreement between us, Bay Alarm Company and John K. La Rue, the
preexisting investors, and PWT Acquisition Corp. a corporation newly formed by
an equity investment group led by Safeguard 98 Capital, L.P. and William Blair
Capital Partners VI, L.P. to effect the recapitalization. PWT was capitalized
through an investment of approximately $31.5 million in preferred stock and
$0.9 million in common stock of PWT by certain equity investors, including
Safeguard 98 Capital, L.P., SCP Private Equity Partners, L.P., TL Ventures III
L.P., EnerTech Capital Partners, William Blair Capital Partners VI, L.P., and
Mr. Wallace W. Griffin, who was named our President and Chief Executive Officer
upon the completion of the recapitalization. Immediately following the merger,
we sold approximately $4.7 million of additional common stock to the equity
investors.

   In accordance with the merger agreement:

  (1) PWT was merged with and into Pac-West, with Pac-West being the
      surviving corporation;

  (2) the outstanding preferred stock of PWT Acquisition Corp. was converted
      into our convertible redeemable preferred stock and the outstanding
      common stock of PWT Acquisition Corp. was converted into Pac-West's
      common stock;

  (3) the existing stockholders received an aggregate of $73.6 million in
      cash, shares of convertible redeemable preferred stock and common stock
      having an aggregate value for purposes of the recapitalization of
      approximately $15.5 million, and an aggregate of $400,000 for their
      respective agreements not to compete with us following the
      recapitalization; and

  (4) we paid bonuses to certain of our executive officers and employees in
      the aggregate amount of approximately $3.5 million.

   Prior to the recapitalization, Mr. John K. La Rue and Bay Alarm Company held
22% and 78%, respectively, of our outstanding common stock. In connection with
the recapitalization, Mr. La Rue received approximately $16.2 million in cash,
112,553 shares of convertible redeemable preferred stock and 1,069,320 shares
of common stock and Bay Alarm Company received $57.4 million in cash, 399,053
shares of convertible redeemable preferred stock and 3,791,060 shares of common
stock. Immediately after the recapitalization, Mr. La Rue and Bay Alarm held
6.1% and 21.7%, respectively, of our outstanding common stock.

   Under the merger agreement, Mr. La Rue and Bay Alarm Company will also be
entitled to receive additional consideration in the form of an earnout payment
in the event we achieve certain adjusted EBITDA levels following the
recapitalization. The amount of such payment will be based upon:

  (1) our adjusted EBITDA for the earnout period from January 1, 1998 through
      December 31, 1998, which includes the amount of unpaid reciprocal
      compensation from Pacific Bell and GTE for the earnout period we
      receive before December 31, 1999, if any; and

  (2) the amount of unpaid reciprocal compensation for the earnout period we
      receive from Pacific Bell and GTE after December 31, 1999.

The earnout payment will be equal to:

  (1) $2.50 for every $1.00 that our adjusted EBITDA for the fiscal year
      ended December 31, 1998, including any unpaid reciprocal compensation
      related to the earnout period received on or prior to December 31,
      1999, exceeds $17.0 million; plus

  (2) the amount by which the sum of:

    (A) the amount of any unpaid reciprocal compensation we receive after
        December 31, 1999 with respect to the earnout period; plus

    (B) the amount our adjusted EBITDA during the earnout period

    exceeds $17.0 million.

The earnout payment cannot exceed $20.0 million.

                                       60
<PAGE>

   The earnout payment will be calculated and paid after the delivery of the
final audited financial statements for the earnout period and on each separate
occasion thereafter that we receive any unpaid compensation. Any earnout
payment will take into account any prior earnout payment made under the merger
agreement. The earnout payment is also subject to possible adjustment under the
merger agreement by agreement between us and Mr. LaRue and Bay Alarm Company as
a result of a material acquisition, divestiture or other material transaction
outside of the ordinary course of our business during the earnout period. No
earnout payment was payable as of December 31, 1998. On September 9, 1999, Pac-
West entered into a settlement agreement with Pacific Bell regarding our claims
for unpaid reciprocal compensation under our prior interconnection agreement.
Under the terms of the settlement agreement, Pacific Bell agreed to pay $20.0
million to Pac-West and $20.0 million to certain stockholders of Pac-West as of
the date of the recapitalization in settlement of those claims. As a result of
these payments, the terms of our September 1998 recapitalization requiring
additional distributions to certain of our shareholders have been satisfied.

   In accordance with the merger agreement, Mr. La Rue and Bay Alarm Company
have agreed to indemnify us and certain of our related parties for all
liabilities and other losses arising from, among other things:

  (1) any breach by Pac-West of any representation, warranty, covenant or
      agreement we made in the merger agreement or in any schedule, exhibit,
      or other related document;

  (2) any claims of any brokers, finders, our employees or consultants
      relating to the transactions contemplated by the merger agreement not
      specifically set forth in or contemplated by the merger agreement; or

  (3) any claim by any person other than PWT Acquisition Corp. or its
      affiliates with respect to, or arising as a result of, any
      reorganization, liquidation, dissolution, recapitalization, non due
      course borrowing, merger, consolidation, sale or purchase of assets or
      similar transactions proposed prior to closing of the merger; provided
      that Mr. La Rue and Bay Alarm Company receive notice of such loss
      within the applicable time periods set forth in the merger agreement.

   Subject to certain exceptions, Mr. La Rue and Bay Alarm Company do not have
any obligation to indemnify any of the indemnified parties from any losses
caused by the breach or alleged breach of any representation or warranty
contained in the merger agreement until the indemnified parties collectively
suffer related aggregate losses in excess of $500,000, which acts as a
deductible. Mr. La Rue and Bay Alarm Company have an obligation to indemnify
the indemnified parties for all losses suffered by any of the indemnified
parties in excess of the deductible, provided that Mr. La Rue and Bay Alarm
Company do not have any obligation to indemnify the indemnified parties from
such aggregate losses in excess of an indemnity cap of $15.0 million. Despite
the above, breaches or alleged breaches of certain post-closing covenants or
agreements contained in the merger agreement will not be subject to the
deductible or the indemnity cap.

   The merger agreement contains representations and warranties typical of
those kinds of agreements, including, for example, those relating to corporate
organization and capitalization, the valid authorization, execution, delivery
and enforceability of all transaction documents, the financial statements, the
absence of material adverse changes in the business, assets, financial
condition and results of operations, the absence of material undisclosed
liabilities, tax matters, the quality and title of personal and real property,
material contracts, intellectual property, employee benefits plans,
environmental matters, compliance with laws, governmental authorizations,
permits and licenses and insurance matters. Generally, our representations and
warranties expire thirty days after receipt of the audited financial statements
for fiscal 1999 except that those relating to tax matters survive until the
expiration of the applicable statute of limitations and certain other
representations and warranties which survive indefinitely.

   The foregoing summary of the material terms of the merger agreement and
related matters does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all of the provisions of the merger
agreement, including the definitions of certain terms therein and the exhibits
and schedules hereto.

Consulting Agreement

   On June 30, 1998, we entered into a Consulting Agreement with Wallace W.
Griffin which terminated September 16, 1998. In accordance with such agreement,
Mr. Griffin provided financial and management consulting services to us and
received fees totaling approximately $60,000. In addition, in accordance with
the

                                       61
<PAGE>

merger agreement, we reimbursed Safeguard for payments of $143,000 made to Mr.
Griffin in connection with services rendered prior to June 30, 1998. After the
recapitalization, Mr. Griffin became our President and Chief Executive Officer
in accordance with his employment agreement with us.

Shareholders Agreement

   In connection with the recapitalization, all of our shareholders entered
into a shareholders agreement. This agreement provides for, among other things,
the nomination of and voting for a total of nine directors of Pac-West, as
follows:

  (1) one representative to be designated by John K. La Rue, provided that
      John K. La Rue initially serves as that representative;

  (2) one representative to be designated by Bay Alarm Company, provided that
      Bruce A. Westphal initially serves as that representative;

  (3) one representative to be designated by the holders of a majority of the
      common stock originally purchased by William Blair Capital Partners VI,
      L.P. and its permitted transferees, provided that David G. Chandler
      initially serves as that representative;

  (4) one representative to be designated by the holders of a majority of the
      common stock originally purchased by SCP Private Equity Partners, L.P.
      and its permitted transferees, provided that Samuel A. Plum initially
      serves as that representative;

  (5) one representative to be designated by the holders of a majority of the
      common stock originally purchased by Safeguard 98 Capital, L.P. and its
      permitted transferees, provided that Jerry L. Johnson initially serves
      as that representative;

  (6) one representative to be designated by TL Ventures III, L.P. and its
      permitted transferees for so long as it holds any shares, provided that
      Mark J. DeNino initially serves as that representative;

  (7) our chief executive officer; and

  (8) two independent directors.

One of the independent directors will serve on our compensation committee and
one will serve on our audit committee. The shareholders agreement generally
restricts the transfer of any shares of convertible redeemable preferred or
common stock held by the parties thereto by granting certain parties thereto
rights of first offer and participation rights in connection with any proposed
transfer by any other party, subject to certain exceptions. In addition, the
shareholders agreement requires each party to consent to a sale of Pac-West to
an independent third party if such sale is approved by the board of directors.
Subject to certain exceptions, we have agreed not to issue, sell or otherwise
transfer for consideration to any person at any time prior to a registered
public offering, any shares of common stock, or securities convertible or
exercisable into common stock, unless certain of the parties to the
shareholders agreement are given the opportunity to subscribe for and purchase
their pro rata portion of such additional shares at the same price and on the
same terms. The provisions of the shareholders agreement automatically
terminate upon the closing of this offering.

Registration Agreement

   In connection with the recapitalization, all of our shareholders entered
into a registration agreement. In accordance with the registration agreement,
at any time prior to the third anniversary of the closing of the
recapitalization, Safeguard may request we grant a rights offering to the
holders of our common stock, consisting of the right to purchase a number of
shares of our common stock as determined by our board of directors. The
exercise price of such rights in the rights offering will be determined by
negotiation among ourselves, the underwriters and the selling stockholders. As
a result of Pac-West's agreement to complete and to pay the fees and expenses
incurred in completing the directed share subscription program, Safeguard has
agreed to waive its right to request a rights offering. After the earlier of
180 days after the consummation of

                                       62
<PAGE>

this offering or the third anniversary of the closing of the recapitalization,
the registration agreement will grant demand registration rights to each of the
four equity investors in the recapitalization and their successors. Each of the
four equity investors in the recapitalization may request one registration at
our expense under the Securities Act of 1933 of all or any portion of their
Pac-West common stock on Form S-1 or other similar long-form registration and
an unlimited number of Form S-2 or S-3 or other similar short-form
registrations, provided that the aggregate offering value of the registrable
securities requested to be registered in any long-form registration must equal
at least $25 million if the registration is our initial registered public
offering, at least $5 million in all other long-form registrations and at least
$1 million in all short-form registrations. In the event that any one of the
four equity investors in the recapitalization makes such a demand registration
request, all other parties to the registration agreement will be entitled to
participate in such registration. The registration agreement will also grant to
the parties thereto piggyback registration rights with respect to all other
registrations of our common stock and we, subject to limited exceptions, will
pay all expenses related to the piggyback registrations.

Non-Competition; Non-Solicitation; Confidentiality Agreements

   In connection with the recapitalization and in accordance with the terms of
the merger agreement, Mr. La Rue and Bay Alarm Company each have entered into a
covenant not to compete with Pac-West, not to engage, and not to permit any
affiliate to engage, for a noncompete period of two years after the closing
date of the recapitalization in any business which:

  (1) provides telecommunication services of the type provided as of the
      closing date by Pac-West; or

  (2) provides services of the type which we have taken significant actions
      as of the closing date to begin providing or of the type we have
      indicated that we plan to begin providing in any business plan or
      similar document delivered to PWT Acquisition Corp. or our shareholders
      prior to the closing date, in each case within Arizona, California,
      Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah and
      Washington, the province of British Columbia, Canada and the
      territories and jurisdictions of Mexico.

The noncompete restrictions do not prohibit any party from being a passive
owner of not more than 5% of the outstanding stock of any class of a
corporation which is publicly traded; and provided further that the noncompete
restrictions do not restrict the activities of any party to the extent such
party has received the consent of our board of directors to such activities.

   In accordance with their respective employment agreements, Messrs. La Rue,
Griffin, Bryson, Meyer and Mills have agreed to forfeit any severance
obligations owing to such executives in the event of their breach of similar
noncompetition provisions. For purposes of Mr. Meyer's and Mr. Mills'
respective agreements, the restricted territories include Arizona, California,

incorporation and by-laws as anticipated to be in effect upon closing of the
offering. The following summary of the provisions of our capital stock
describes material provisions of, but does not purport to be complete and is
subject to, and qualified in its entirety by, our articles of incorporation and
by-laws that are included as exhibits to the registration statement of which
this prospectus forms a part and by the provisions of applicable law.

Common Stock

   All outstanding shares of our common stock are fully paid and non-
assessable. Subject to the prior rights of the holders of our preferred stock,
the holders of our common stock are entitled to receive dividends at such time
and in such amounts as our board of directors may determine. See "Dividend
Policy" for a further description of your dividend rights.

   The shares of our common stock are not convertible and holders thereof have
no preemptive or subscription rights to purchase any of our securities nor will
holders be entitled to the benefits of any redemption or sinking fund
provisions. Upon our liquidation, dissolution or winding up, the holders of our
common stock are entitled to receive pro rata all of our assets which are
legally available for distribution, after payment of all debts and other
liabilities and subject to the prior rights of any holders of our preferred
stock which is then outstanding. Each outstanding share of our common stock is
entitled to one vote on all matters submitted to a vote of stockholders. There
are cumulative voting rights with respect to the election of directors.

   Our common stock has been approved for quotation on the Nasdaq National
Market under the symbol PACW.

Convertible Redeemable Preferred Stock

   The convertible redeemable preferred stock has a preference amount over the
common stock with respect to any distribution by Pac-West to the holders of our
capital stock or with respect to any liquidation, dissolution or winding up of
Pac-West equal to the liquidation value of such shares, $25.72, plus an amount
which accrues on a daily basis at a rate of 10% per annum on the original cost
of such shares, $25.72, compounded quarterly. After payment of the preference
amount, the convertible redeemable preferred stock and the common stock share
ratably in any distribution made by us to the holders of our capital stock or
with respect to any liquidation, dissolution or winding up of Pac-West.

   In connection with a registered public offering by us of equity or debt
securities, or rights to acquire equity or debt securities, the holders of a
majority of the outstanding convertible redeemable preferred stock have the
right to convert all outstanding convertible redeemable preferred stock into
shares of common stock by delivering written notice to us at least 15 days
prior to the expected closing of such public offering. In addition, any holder
of the outstanding convertible redeemable preferred stock may convert its
shares of convertible redeemable preferred stock to shares of common stock in
connection with a public offering by delivering written notice to us at least
30 days prior to the expected closing of such public offering. In connection
with this offering, each share of convertible redeemable preferred stock will
be converted into that number of shares of common stock determined by dividing
the preference amount by the initial public offering price of the common stock.

                                       68
<PAGE>

   The convertible redeemable preferred stock is subject to immediate
redemption upon certain events of bankruptcy and insolvency. The foregoing
redemption rights are all subject to our having sufficient funds that are:

  (1) legally available in accordance with the General Corporation Law of
      California for the redemption of the shares of convertible redeemable
      preferred stock; and

  (2) permitted to be used for the redemption of such shares of convertible
      redeemable preferred stock in accordance with any debt financing
      agreements of Pac-West, including the indenture governing the senior
      notes.

   The holders of convertible redeemable preferred stock have no right to vote
on matters submitted to a vote of our stockholders, except as otherwise
required by law.

Certain Anti-Takeover, Limited Liability and Indemnification Provisions

 Classified Board of Directors

   Our bylaws provide that, following the closing of this offering, our Board
of Directors will be divided into three classes of directors, with each class
serving staggered three-year terms. As a result, approximately one-third of our
Board of Directors will be elected each year. The classified board provision
will help ensure the continuity and stability of our Board of Directors and our
business strategies and policies as determined by our Board of Directors. The
classified board provision could have the effect of discouraging a third party
from making an unsolicited tender offer or otherwise attempting to obtain
control of us without the approval of our Board of Directors even where such
acquisition could have resulted in increased value to Pac-West shareholders. In
addition, the classified board provision could delay shareholders who do not
like the policies of our Board of Directors from electing a majority of our
Board of Directors for two years.

 No Shareholder Action by Written Consent: Board Vacancies

   Our bylaws provide that shareholders may not vote by written consent in lieu
of a meeting to fill a vacancy on the Board of Directors.

 Limitations on Liability and Indemnification of Officers and Directors

   Our articles of incorporation provide that the liability of our directors
for monetary damages shall be eliminated to the fullest extent permissible
under California law. However, this provision does not affect the directors'
responsibilities under any other laws, such as the federal securities laws.

   Our articles of incorporation also provide that we are authorized to provide
indemnification of our agents through bylaw provisions, agreements with agents,
votes of shareholders or disinterested directors, or otherwise, to the fullest
extent permissible under California law. Accordingly, our bylaws provide
indemnification, to the maximum extent and in the manner permitted by
California law, to each of our directors, officers, employees and agents
against expenses, judgments, fines, settlements, and other amounts actually and
reasonably incurred in connection with any proceeding arising by reason of the
fact that such person is or was a director, officer, employee or agent of us.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is First Union
National Bank.

                          DESCRIPTION OF INDEBTEDNESS

Senior Credit Facility

   Our senior credit facility provides for maximum borrowings of $40.0 million
for working capital and other corporate purposes. The senior credit facility
has a three-year term ending June 15, 2002, and our indebtedness under that
facility is secured by all of our assets, including but not limited to our
equipment, inventory, receivables and related contracts, investment property,
computer hardware and software, bank accounts and all other goods and rights of
every kind and description.

   Our borrowings under the senior credit facility will bear interest, at our
option, at:

  (1) the base rate, as defined in the senior credit facility, or

  (2) the LIBOR rate, as defined in the senior credit facility, plus between
      2.25% and 3.5%. As of June 30, 1999, the borrowing rate under this
      facility would have been approximately 8.00%.

   We are required to pay the lender under the senior credit facility a
commitment fee, payable in arrears on a quarterly basis, on the average unused
portion of the senior credit facility during such period. We may also be
required to pay an annual agency fee to the agent of the lender. In addition,
we paid an arrangement fee. The agent and the lender will receive and continue
to receive such other fees as may be separately agreed upon with the agent.

   The senior credit facility requires us to meet certain financial tests,
including, for example, maximum levels of debt as a ratio of EBITDA, as defined
in the senior credit facility, minimum interest coverage and maximum amount of
capital expenditures. The senior credit facility contains certain covenants
which, among other things, limit the incurrence of additional indebtedness,
investments, dividends, transactions with affiliates, asset sales,
acquisitions, mergers and consolidations, prepayments of other indebtedness,
liens and encumbrances and other matters customarily restricted in such
agreements.

   The senior credit facility contains customary events of default including,
for example, payment defaults, breaches of representations and warranties,
covenant defaults, cross-defaults to certain other indebtedness, certain events
of bankruptcy and insolvency, judgment defaults, failure of any guaranty or
security document supporting the senior credit facility to be in full force and
effect and change of control of Pac-West.

Senior Notes

   The following description is a summary of the material provisions of our
senior notes and the senior notes indenture. It does not restate those
agreements in their entirety. We urge you to read the senior notes indenture
and sample note, which have been previously filed with the SEC.

 General Characteristics

   The senior notes mature on February 1, 2009 and are limited to an aggregate
stated principal amount at maturity of $150 million. They accrue interest at
the rate of 13 1/2% per annum payable semi-annually in arrears and are a
general unsecured obligation. However, we have purchased and pledged to the
trustee, as security for the benefit of the holders of the senior notes, a
portfolio of U.S. government securities in an amount sufficient to provide for
payment in full of the first two scheduled interest payments due under the
senior notes, the first of which was paid on August 2, 1999.

 Optional Redemption

   At any time prior to February 1, 2002, we may redeem up to 35% of the
aggregate principal amount of senior notes originally issued at a redemption
price of 113.50% plus accrued and unpaid interest with the net

                                       70
<PAGE>

cash proceeds of one or more underwritten public equity offerings of common
stock in which the gross proceeds to us are at least $20 million; provided
that:

  . at least $97.5 million in aggregate principal amount of the notes remains
    outstanding immediately after such a redemption and

  . the redemption occurs within 45 days of the date of the closing of such
    public equity offering.

   After February 1, 2004, we may redeem all or a part of the senior notes at
the redemption prices set forth below plus accrued and unpaid interest if
redeemed during the twelve-month period beginning February 1 of the years
indicated below:

 Repurchase at the Option of Holders

   If we sell certain assets or experience a change of control, each holder of
the senior notes will have the right to require us to repurchase all or any
part of that holder's senior notes for 101% of the aggregate principal amount
of the senior notes repurchased plus accrued and unpaid interest.

 Certain Covenants

   The senior notes are under an indenture with Norwest Bank Minnesota, N.A.,
as trustee. The senior notes indenture will, among other things, restrict our
ability to:

  . borrow money;

  . pay dividends on stock or repurchase stock;

  . make investments;

  . use assets as security in other transactions; and

  . sell certain assets or merge with or into other companies.

                        SHARES ELIGIBLE FOR FUTURE SALE

   After completion of this offering, there will be 33,852,405 shares of our
common stock issued and outstanding based on the 17,587,458 shares outstanding
as of June 30, 1999, and including the 11,400,000 shares of common stock being
sold by us in this offering and the 4,864,947 shares of common stock issuable
upon conversion of our outstanding convertible redeemable preferred stock,
based on the preference amount as of June 30, 1999 and a conversion price of
$10.00 per share. Of these shares, the 12,600,000 shares of common stock to be
sold in this offering will be immediately eligible for sale in the public
market, except for shares owned at any time by our affiliates within the
meaning of Rule 144 under the Securities Act. The remaining 21,252,405 issued
and outstanding shares are restricted securities within the meaning of Rule 144
and may not be publicly resold, except in compliance with the registration
requirements of the Securities Act or pursuant to an exemption from
registration, including that provided by Rule 144. There is currently no public
market for our common stock. We expect that trading of our common stock on the
Nasdaq National Market will commence on November 4, 1999. We do not make any
prediction regarding the effect, if any, that future sales of shares, or the
availability of our shares for future sale, will have on the market price of
our common stock. The market price of our common stock can be adversely
affected by sales of substantial amounts of common stock or by the perception
that these sales could occur.

Rule 144

   In general, under Rule 144, a person, or persons whose shares are
aggregated, who has beneficially owned restricted securities for at least one
year, including a person who may be deemed affiliate, is entitled to sell
within any three month period a number of our shares of common stock that does
not exceed the greater of:

  . 1% of the then-outstanding shares of our common stock; or

  . the average weekly trading volume of our common stock on the Nasdaq
    National Market during the four calendar weeks preceding the date on
    which notice of the sale is filed with the Securities and Exchange
    Commission.

   Sales under Rule 144 are subject to restrictions relating to manner of sale,
notice and the availability of current public information about us. A person
who is not our affiliate at any time during the 90 days preceding a sale and
who has beneficially owned shares for at least two years would be entitled to
sell shares following this offering under Rule 144(k) without regard to the
volume limitations, manner of sale provisions or notice requirements of Rule
144.

Rule 701

   Our employees, directors, officers or consultants who purchased our shares
in connection with a written compensatory plan or contract may be entitled to
rely on the resale provisions of Rule 701. Rule 701 permits non-affiliates to
sell their Rule 701 shares without having to comply with the public
information, holding period, volume limitation or notice provisions of Rule
144. Affiliates may sell their Rule 701 shares without having to comply with
Rule 144's holding period restrictions. In each of these cases, Rule 701 allows
the shareholders to sell 90 days after the date of this prospectus.

Lock-up agreements

   Our directors, executive officers, and shareholders, who collectively hold
21,252,405 of the shares of common stock to be outstanding after this offering,
have agreed, subject to limited exceptions, not to sell, offer to sell or
otherwise dispose of our common stock or securities convertible into or
exercisable or exchangeable for our common stock for a period of 180 days after
the date of this prospectus without the prior written consent of Bear, Stearns
& Co. Inc., on behalf of the underwriters, except Safeguard 98 Capital, L.P.
may, pursuant to the terms of a long term incentive plan, transfer
approximately 10% of its pre-offering holdings to Safeguard Scientifics'
employees, who will not be subject to a lock-up agreement.

market, subject to the resale limitations of Rule 144 applicable to our
affiliates.

</TABLE>

   The underwriting agreement provides that the obligations of the several
underwriters are subject to approval of legal matters by their counsel and to
various other conditions. Under the underwriting agreement, the underwriters
are obligated to purchase and pay for all of the shares of common stock set
forth in the table above, other than those covered by the over-allotment option
described below, if they purchase any of the shares.

   The underwriters propose to initially offer some of the shares directly to
the public at the offering price set forth on the cover page of this prospectus
and some of the shares to dealers at this price less a concession not in excess
of $0.42 per share. The underwriters may allow, and dealers may re-allow,
concessions not in excess of $0.10 per share on sales to other dealers. After
the initial offering of the shares to the public, the underwriters may change
the offering price, concessions and other selling terms. The underwriters do
not intend to confirm sales to any accounts over which they exercise
discretionary authority.

                                       74
<PAGE>

   We have granted the underwriters an option exercisable for 30 days from the
date of the underwriting agreement to purchase up to 1,365,000 additional
shares at the offering price less the underwriting discount. The underwriters
may exercise this option solely to cover over-allotments, if any, made in
connection with this offering. To the extent underwriters exercise this option
in whole or in part then each of the underwriters will become obligated,
subject to conditions, to purchase a number of additional shares approximately
proportionate to each underwriter's initial purchase commitment as indicated in
the preceding table.

   We and Safeguard Scientifics have agreed to indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act.

   Our directors, executive officers and shareholders, who collectively hold
21,252,405 of the shares of common stock to be outstanding after this offering,
have agreed, subject to limited exceptions, not to sell or offer to sell or
otherwise dispose of any shares of common stock or securities convertible into
or exercisable or exchangeable for our common stock, for a period of 180 days
after the date of this prospectus without the prior written consent of Bear,
Stearns & Co. Inc., on behalf of the underwriters, except Safeguard 98 Capital,
L.P. may, pursuant to the terms of a long term incentive plan, transfer
approximately 10% of its pre-offering holdings to Safeguard Scientifics'
employees, who will not be subject to a lock-up agreement.

   In addition, we have agreed that for a period of 180 days after the date of
this prospectus we will not offer, sell or otherwise dispose of any shares of
common stock except for the shares offered in this offering and any shares
offered in connection with employee benefit plans and other limited exceptions,
without the consent of Bear, Stearns & Co. Inc., on behalf of the underwriters.

   Prior to the offering, there has been no public market for our common stock.
Consequently, the initial offering price for the common stock will be
determined by negotiations between us and the representatives of the
underwriters. Among the factors to be considered in these negotiations will be:

  . our results of operations in recent periods;

  . estimates of our business potential;

  . an assessment of our management;

  . prevailing market conditions; and

  . the prices of similar securities of generally comparable companies.

   Our common stock has been approved for quotation on the Nasdaq National
Market under the symbol "PACW." We cannot assure you, however, that an active
or orderly trading market will develop for the common stock or that our common
stock will trade in the public markets subsequent to the offering at or above
the initial offering price.

   In order to facilitate the offering, the underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
common stock during and after the offering. Specifically, the underwriters may
over-allot or otherwise create a short position in the common stock for their
own account by selling more shares of common stock than we have actually sold
to them. The underwriters may elect to cover any short position by purchasing
shares of common stock in the open market or by exercising the over-allotment
option granted to the underwriters. In addition, the underwriters may stabilize
or maintain the price of the common stock by bidding for or purchasing shares
of common stock in the open market and may impose penalty bids, under which
selling concessions allowed to syndicate members or other broker-dealers
participating in the offering are reclaimed if shares of common stock
previously distributed in the offering are repurchased in connection with
stabilization transactions or otherwise. The effect of these transactions may
be to stabilize or maintain the market price at a level above that which might
otherwise prevail in the open market and these transactions may be discontinued
at any time. The imposition of a penalty bid may also affect the price of the
common stock to the extent that it discourages resales. No representation is
made as to the magnitude or effect of these activities.

                                       75
<PAGE>

   The underwriters have reserved for sale, at the initial public offering
price, up to 477,900 shares of common stock for employees, directors and other
persons associated with us who express an interest in purchasing these shares
of common stock in the offering. The number of shares available for sale to the
general public in the offering will be reduced to the extent these persons
purchase reserved shares. Any reserved shares not purchased by these persons
will be offered by the underwriters to the general public on the same terms as
the other shares offered in this offering.

   Banc of America Securities LLC and its affiliates own approximately 1.8% of
our common stock, which was acquired in the recapitalization of Pac-West on
September 16, 1998. Banc of America Securities LLC and First Union Securities,
Inc. also own a portion of our senior notes as part of their market-making
activities in the senior notes. The underwriters have and may, from time to
time, engage in transactions with, and perform services for, us in the ordinary
course of their business.

   The following table shows the underwriting discount to be paid to the
underwriters in connection with this offering. These amounts are shown assuming
both no exercise and full exercise of the underwriters' option to purchase
additional shares of common stock.

                      Directed Share Subscription Program

   As part of this offering, we are offering 2,300,000 shares and Safeguard
Scientifics is offering up to 1,200,000 shares of our common stock beneficially
owned by it in a directed share subscription program to shareholders of
Safeguard Scientifics, one of our principal shareholders. Safeguard Scientifics
is an underwriter with respect to the shares of our common stock offered to the
shareholders of Safeguard Scientifics. Safeguard Scientifics is not an
underwriter with respect to the other shares of our common stock offered and is
not included in the term "underwriter" as used elsewhere in this prospectus.
The underwriters are not purchasing the shares in the directed share
subscription program, and are not an "underwriter" with respect to those
shares. Safeguard has not participated in any discussions or negotiations with
the Company and the underwriters regarding the initial public offering price.
Safeguard will not have any right to seek indemnification from Pac-West
regarding its agreement to accept underwriter liability with respect to the
shares included in the directed share subscription program.

   Safeguard Scientifics' shareholders may subscribe for one share of our
common stock for every ten shares of Safeguard Scientifics' common stock held
by them and may not transfer the opportunity to subscribe to another person
except involuntarily by operation of law. Persons who owned at least 100 shares
of Safeguard Scientifics' common stock as of September 7, 1999 are eligible to
purchase shares directly from us or Safeguard Scientifics under the program.
Shareholders who own less than 100 shares of Safeguard Scientifics' common
stock will be ineligible to participate in the directed share subscription
program. Subscription orders will be satisfied first from the shares being sold
by us and then from the shares offered by Safeguard Scientifics. If any of the
shares offered by us under the program are not purchased by the shareholders of
Safeguard Scientifics, Safeguard Scientifics, directly or through its wholly-
owned subsidiary Safeguard Delaware, Inc., will purchase these shares from us
at the closing of this offering. This purchase obligation may not be
transferred to anyone else and the only condition to the purchase obligation is
the consummation of the underwritten public offering. Although these shares
will have been purchased directly from us as part of a registered offering,
Safeguard Scientifics is one of our affiliates and may only sell these shares
in accordance with Rule 144 restrictions or in subsequent registered offerings.
See "Shares Eligible For Future Sale." In addition, Safeguard Scientifics has
agreed not to offer, sell or otherwise dispose of any shares of our common
stock purchased by it in the directed share subscription program for a period
of 180 days after the date of this prospectus. Sales under the directed share
subscription program will close on the closing of the sale of the other

                                       76
<PAGE>

shares offered to the public. It is expected that sales under the directed
share subscription program will be reflected in each purchaser's book-entry
account at the Depository Trust Company, if any, shortly after the closing of
these sales. After the closing of these sales, we will mail stock certificates
to all purchasers who do not maintain book-entry accounts at the Depository
Trust Company.

   Prior to this offering, Safeguard Scientifics beneficially owned 3,622,649
shares or approximately 16.1% of our common stock. After this offering,
Safeguard Scientifics will beneficially own 2,422,649 shares or approximately
7.2% of our common stock, assuming that all shares offered in the directed
share subscription program are purchased by shareholders of Safeguard
Scientifics. If the shareholders of Safeguard Scientifics do not purchase any
of the shares offered in the directed share subscription program and Safeguard
Scientifics purchases all of the shares offered by us in the directed share
subscription program, Safeguard Scientifics will beneficially own 5,922,649
shares or approximately 17.5% of our common stock after this offering. The
purchase price under the program, whether paid by Safeguard Scientifics or its
shareholders, will be the same price per share as set forth on the cover page
of this prospectus. For purposes of this prospectus, when we present
information that reflects this offering, we have assumed that all shares
offered under the directed share subscription program are purchased by
shareholders of Safeguard Scientifics.

   We have entered into an agreement to pay Bear, Stearns & Co. Inc. a
financial advisory fee of up to $690,000 or an amount equal to 3% of the
aggregate initial public offering price of all the shares being sold by us
through the directed share subscription program, including shares that may be
sold to Safeguard Scientifics. In addition, Safeguard Scientifics has agreed to
pay Bear, Stearns & Co. Inc. a financial advisory fee of up to $360,000 or an
amount equal to 3% of the aggregate initial public offering price of all the
shares being sold by Safeguard Scientifics through the directed share
subscription program. The financial advisory fees compensate Bear, Stearns &
Co. Inc. for its financial advice relating to the directed share subscription
program. Safeguard Scientifics will not receive any compensation from us or any
other person with respect to this offering, including any underwriting
discounts or commissions.

   The following table shows the per share and total offering price, financial
advisory fee to be paid to Bear, Stearns & Co. Inc. and the proceeds, before
expenses, to us.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders
of Pac-West Telecomm, Inc.:

   We have audited the accompanying balance sheets of Pac-West Telecomm, Inc.
(a California corporation) as of December 31, 1997 and 1998, and the related
statements of operations, changes in stockholders' equity (deficit) and cash
flows for the three-month period from date of commencement (October 1, 1996) to
December 31, 1996, and for the years ended December 31, 1997 and 1998. In
addition, we have audited the statements of operations and cash flows of the
predecessor telephone and answering service divisions of Pac-West Telecomm,
Inc. (see Note 1) for the nine-month period ended September 30, 1996. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Pac-West Telecomm, Inc. as
of December 31, 1997 and 1998, and the results of its operations and its cash
flows for the three-month period from date of commencement (October 1, 1996) to
December 31, 1996, and for the years ended December 31, 1997 and 1998, and the
results of operations and cash flows of the predecessor telephone and answering
service divisions of Pac-West Telecomm, Inc. for the nine-month period ended
September 30, 1996, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS

                               December 31, 1998

1. Organization:

   Pac-West Telecomm, Inc. (the Company) is engaged in the business of
providing switched local and long-distance telecommunications services and
"one-stop" integrated telecommunications services to Internet Service Providers
(ISPs), paging companies and other inbound call service providers, as well as
to medium and small businesses, principally within California.

   The Company was incorporated in May 1996 in the state of California as a
wholly owned subsidiary of CalPage (a telephone, answering and paging services
company), also formerly named Pac-West Telecomm, Inc. CalPage transferred its
telephone and answering service divisions (the Predecessor Telephone and
Answering Service Divisions or the "Predecessor") to the Company effective
September 30, 1996 (the Initial Transfer). In conjunction with the Initial
Transfer, CalPage spun off the Company to the stockholders of CalPage. The
accompanying financial statements are presented on the same historical cost
basis as was used prior to the Initial Transfer.

   During 1997, the Company sold the customer base and other assets of its
answering service division (see Note 10).

   The success of the Company is highly dependent upon several factors. These
factors include the Company's ability to penetrate additional markets and to
manage network growth and technological change within the telecommunications
industry, the successful implementation of local and enhanced services to its
customers including ISPs, and competition from preexisting and new providers of
local and long-distance services, as well as positive and timely responses
regarding governmental regulations.

   Additionally, the Company is managed by a limited number of key individuals,
several of whom are subject to employment contracts. The Company is also
dependent on the development of an effective sales force and the retention of
skilled and qualified personnel.

   As of December 31, 1998, the Company's borrowings and other long-term
obligations totaled $100,248,000 and the Company had a stockholders' deficit of
$74,113,000. As discussed in Note 11, in January 1999, the Company issued
$150,000,000 of 13.5 percent senior notes due on February 1, 2009. A portion of
the proceeds from these notes was used to repay the senior secured borrowings.
The balance of the proceeds will be used for future capital expenditures and
working capital needs, including the establishment of an interest reserve to
cover certain initial interest payments due under the senior notes.

 Basis of Presentation

   The accompanying financial statements present the financial position of the
Company as of December 31, 1997 and 1998, and the results of its operations and
its cash flows for the period from commencement (October 1, 1996) to December
31, 1996, and for the years ended December 31, 1997 and 1998. In addition, the
accompanying financial statements present the results of the Predecessor's
operations and cash flows for the nine-month period ended September 30, 1996.

   The Predecessor was a division of CalPage during the nine-month period ended
September 30, 1996. Accordingly, the results of the Predecessor's operations
and its cash flows were recorded and reported by CalPage as an integral part of
CalPage's total operations. The Company has used its best efforts to derive the
appropriate information from the books and records of CalPage and has by
necessity applied certain

                            PAC-WEST TELECOMM, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

assumptions in identifying and allocating costs and expenses to separately
report the results of operations and cash flows of the Predecessor for the
nine-month period ended September 30, 1996 in the accompanying financial
statements.

   Allocated selling, general and administrative expenses for the nine-month
period ended September 30, 1996, were $1,111,000.

   Assumptions used were based on headcount and job descriptions, facility
utilization, and divisional revenues. Management believes this method is a
reasonable allocation method and that the resulting amounts approximate the
amounts that would have been incurred if the Predecessor was operated on a
stand-alone basis. Revenues, direct costs, depreciation and amortization and
interest expense have been recorded based on the specific activities of the
Predecessor.

   Due to the significant changes in the Company's operations since September
30, 1996, the Company believes that the financial information of the
Predecessor is not directly comparable to the Company's results of operations.

   On September 16, 1998, the Company completed a merger with PWT Acquisition
Corp. (PWT) and a recapitalization of the Company (the Transaction). PWT was
formed by a group of investors (the New Stockholders) for the purpose of
injecting additional equity into the Company and effecting the
recapitalization. In connection with the Transaction, PWT was merged into the
Company, with the Company being the surviving corporation.

   In connection with the Transaction, Bay Alarm Company and Mr. John La Rue
(the Existing Stockholders) received cash payments of approximately $74 million
(primarily financed through senior secured borrowings--see Note 3), as well as
shares of newly issued preferred and common stock of the Company in exchange
for a substantial portion of their ownership interests. Additionally, at the
consummation of the Transaction, the Company paid transaction bonuses and
consultant's costs totaling approximately $3.8 million which are included in
the accompanying statements of operations. Under the terms of the Transaction,
the Existing Stockholders of the Company are entitled to receive additional
consideration up to $20 million in the event that the Company achieves certain
earnings targets (including receipt of certain billings under dispute--see Note
5) subsequent to the recapitalization. As of December 31, 1998, none of these
earnings targets were achieved and accordingly, no amounts have been accrued at
December 31, 1998 for payment of any additional consideration. Immediately
following consummation of the Transaction, the Existing Stockholders continued
to hold approximately 28 percent of the issued and outstanding common stock of
the Company. As a result of the continued significant ownership interests of
the Existing Stockholders, no adjustments have been made to the historical
carrying amounts of the Company's assets and liabilities as a result of the
Transaction.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


 Use of Estimates

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
the accompanying notes. Actual results could differ from those estimates. See
Note 1 for assumptions used for Predecessor financial reporting.

 Regulation and Competition

   Rates charged by the Company for certain telephone services are subject to
the approval of various regulatory authorities. Trends in the
telecommunications industry point toward increased competition in virtually all
markets and the continued deregulation or alternative regulation of
telecommunications services in many jurisdictions.

 Revenue Recognition

   Except for certain billings under dispute with two significant ILEC's as
described in Note 5, the Company recognizes revenues for telecommunications
services when service is provided. Revenues from the sale of telecommunications
products are recognized upon installation, or if no installation is required,
upon shipment. Initial non-recurring revenues from the installation of
telecommunication products are recognized upon completion of installation to
the extent of direct costs incurred. Any initial non-recurring installation
revenue in excess of direct costs is deferred and amortized over the expected
service contract period, generally two years or less.

 Cash Equivalents

   For purposes of reporting cash flows, the Company considers all highly
liquid investments with an original maturity of three months or less to be cash
equivalents.

 Inventories

   Inventories consist of telephone equipment, parts and installation
materials, which are valued at the lower of cost or market. Cost is determined
by the average-cost method. Provision is made to reduce slow moving inventory
to reflect its estimated net realizable value.

 Other Comprehensive Income

   There were no items of other comprehensive income in any period presented.

 Segment Reporting

   The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 131, "Disclosures about Segments of an Enterprise and Related Information".
As an integrated telecommunications provider, the Company has one reportable
operating segment. While the Company's chief decision-maker monitors the
revenue streams of various services, operations are managed and financial
performance is evaluated based upon the delivery of multiple services over
common networks and facilities. This allows the Company to leverage its costs
in an effort to maximize return. As a result, there are many shared expenses
generated by the various revenue streams; because management believes that any
allocation of the expenses to multiple revenue streams would be impractical and
arbitrary, management does not currently make such allocations internally. The
chief decision-maker does however, monitor revenues streams at a more detailed
level than those depicted in the Company's historical general purpose financial
statements.

</TABLE>

 Reclassifications

   Certain reclassifications have been made to the Company's comparative
financial statements to conform to the current year presentation.

 Equipment, Vehicles and Leasehold Improvements

   Equipment, vehicles and leasehold improvements transferred to the Company
are stated at the net book value on the date of the Initial Transfer.
Subsequent additions are stated at cost. Equipment includes assets acquired
under capital leases. Expenditures for maintenance are charged to expense as
incurred. Upon retirement, the asset cost and the related accumulated
depreciation are removed from the accounts. Gains and losses associated with
dispositions of equipment, vehicles and leasehold improvements are reflected as
a component of other income, net in the accompanying statements of operations.
Equipment, vehicles and leasehold improvements from the Initial Transfer are
depreciated or amortized over their remaining useful lives as of the date of
the Initial Transfer. For subsequent additions including assets acquired under
capital leases, depreciation and amortization is computed using the straight-
line method based on the following estimated useful lives:

<TABLE>
      <C>                                <S>
      Equipment........................  3 to 7 years
      Vehicles.........................  5 years
      Leasehold improvements...........  10 years or life of lease, whichever
                                          is shorter
</TABLE>

   The Company capitalizes interest on self-constructed capital projects when
construction involves considerable time and major expenditures. Such interest
is capitalized as part of the cost of the equipment and leasehold improvement
and is amortized over the remaining life of the assets. Interest is capitalized
based on rates for borrowings that are outstanding over the period required to
complete the asset. In 1998, the Company capitalized $303,000 of interest
related to the construction of assets. Capitalizable interest in all other
periods presented was insignificant.

   Depreciation and amortization of equipment, vehicles and leasehold
improvements was $299,000, $2,204,000 and $4,106,000, for the period from
commencement (October 1, 1996) to December 31, 1996, and for the years ended
December 31, 1997 and 1998, respectively. Depreciation and amortization of
equipment, vehicles and leasehold improvements was $549,000 for the
Predecessor's nine-month period ended September 30, 1996.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


 Deferred Financing Costs, Net

   Deferred financing costs, net consist of capitalized amounts for bank
financing fees, professional fees, and other expenses related to the senior
secured borrowings obtained on September 16, 1998 (see Note 3). Amortization is
computed using the straight-line method over the term of the borrowings through
January 29, 1999. Amortization expense for the year ended December 31, 1998,
was $1,438,000 and is included within interest expense in the accompanying
statements of operations.

 Other Assets

   At December 31, 1998, other assets consist primarily of deferred financing
costs of $1,195,000 associated with the Company's subsequent issuance of senior
notes (see Note 11) and the long-term portion of covenants not to compete of
$150,000. Upon issuance of the senior notes, the deferred financing costs will
be amortized over the estimated maturity of the debt of 10 years.

 Other Accrued Liabilities

   Other accrued liabilities include approximately $424,000 and $1,018,000 as
of December 31, 1997 and 1998, respectively, of amounts collected from
customers for taxes due to various governmental and regulatory authorities.

 Income Taxes

   The Company provides for income taxes in accordance with Statement of
Financial Accounting Standards (SFAS) No. 109, "Accounting for Income Taxes."
SFAS No. 109 requires the asset and liability method of accounting for income
taxes. Under this method, deferred income taxes are recognized for the tax
consequences of "temporary differences" by applying the applicable statutory
tax rate to the differences between the financial statement carrying amounts
and the tax basis of existing assets and liabilities. Under SFAS No. 109, the
effect on deferred taxes of a change in tax rates is recognized in income in
the period that includes the enactment date based on the applicable tax rate.

 Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and for Hedging Activities," effective
for fiscal years beginning after June 15, 1999. Management does not expect
adoption of SFAS No. 133 in future periods to have a significant impact on the
Company's financial statements.

 Income (Loss) Per Share

   Income (loss) per share has been calculated under SFAS No. 128, "Earnings
per Share." SFAS No. 128 requires companies to compute income (loss) per share
under two methods (basic and diluted). Basic net income (loss) per share is
calculated by dividing net income (loss) by the weighted average shares of
common stock outstanding during the period. Diluted net income (loss) per share
information is presented in the accompanying statements of operations as being
the same as basic net income (loss) per share information since the impact of
the issuance of potential common shares from the exercise of common stock
options is antidilutive. The Company evaluated the requirements of the
Securities and Exchange Commission Staff Accounting Bulletin (SAB) No. 98 and
concluded that there are no nominal issuances of common stock or potential
common stock which would be required to be shown as outstanding for all periods
presented herein as outlined in SAB No. 98.

   Net income (loss) applicable to common stockholders has been calculated as
follows:

3. Senior Secured Borrowings:

   On September 16, 1998, concurrent with the Transaction discussed in Note 1,
the Company entered into a senior secured borrowing agreement with several
financial institutions allowing for borrowings up to $100,000,000. The
outstanding balance under this agreement was due at the earlier of the
completion of a high-yield debt offering (see Note 11) or March 16, 1999, with
interest due monthly, bearing interest at a floating rate equal to, at the
Company's option, the base rate (defined as the higher of (a) 0.5 percent above
the latest Federal Funds Rate; and (b) the rate of interest in effect as
publicly announced by the principal lender as its "reference rate"), or the
offshore rate (as defined in the senior secured borrowings agreement) plus 2.0
percent. As of December 31, 1998, the Company had elected to utilize the
offshore rate, which was 8.625 percent, including the additional 2.0 percent.
The borrowings were secured by substantially all assets of the Company. The
Company was subject to certain covenants, which included limitations on
additional debt, restrictions on the payment of dividends and maintenance of
certain interest coverage requirements.

   At December 31, 1998, the Company had senior secured borrowings outstanding
of $91,000,000 and other obligations of $9,000,000. The $9,000,000 of other
obligations related to equipment purchases incurred as of December 31, 1998,
which were subsequently financed through additional senior secured borrowings
(see Note 5).

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   On January 29, 1999, the Company paid off all outstanding senior secured
borrowings and accrued interest through the issuance of a high-yield debt
offering due February 1, 2009 (see Note 11). As a result of the subsequent
refinancing, the senior secured borrowings and other obligations have been
classified as long-term debt and other long-term obligations in the
accompanying balance sheet as of December 31, 1998.

 Extraordinary Item--Loss on Early Extinguishment of Debt

   In conjunction with the Transaction (see Note 1) and the receipt of the
senior secured borrowings during 1998, as discussed in Note 3, the Company
repaid amounts outstanding under notes payable and capital leases for
equipment. The resulting loss from the early extinguishment of the debt of
$695,000, less the applicable income tax benefit of $278,000, has been
reflected as an extraordinary item in the accompanying statements of
operations.

 Line of Credit

   The Company maintained a credit agreement with a bank that provided for a
line of credit with a maximum borrowing limit of $2,500,000. The credit
agreement and related security agreement contained various restrictive
covenants, including restrictions on the incurrence of new liens and long-term
indebtedness except for the financing of new equipment, the payment of
dividends, the entering into business combinations or mergers, and requirements
to maintain certain financial ratios. For the years ended December 31, 1997 and
1998, no amounts were borrowed under this line of credit. During 1998, the
Company terminated the line of credit.

5. Commitments and Contingencies:

 Leases

   The Company leases its four principal facilities in Stockton, Oakland, Los
Angeles and Las Vegas pursuant to noncancelable operating leases that expire in
2002, 2003, 2006 and 2009, respectively. The lease expiring in 2002 also
contains five two-year renewal options. The leases expiring in 2003, 2006 and
2009 also contain two five-year renewal options. Prior to September 16, 1998,
the Company leased certain equipment under capital leases that were repaid in
connection with the Transaction (see Note 1). The Company also leases telephone
equipment and telephone circuits on both a month-to-month basis, as well as
under annual and long-term noncancellable leases. Management of the Company
expects that these leases will be renewed or replaced by other leases in the
normal course of business.

   The Company's future minimum lease payments with initial terms in excess of
one year for the years ending December 31 are as follows:

   Rental expense charged to operations for the period from commencement
(October 1, 1996) to December 31, 1996, and for the years ended December 31,
1997 and 1998, for all operating leases for space was $76,000, $432,000 and
$650,000, respectively. Rental expense charged to operations by the Predecessor
for space for the nine-month period ended September 30, 1996 was $125,000.
Rental expense for space is included in selling, general and administrative
expense in the accompanying statements of operations. Rental expense charged to
operations for telephone circuits and equipment was approximately $1,000,000,
$6,000,000 and $9,935,000 for the period from commencement (October 1, 1996) to
December 31, 1996, and for the years ended December 31, 1997 and 1998,
respectively. Rental expense charged to operations by the Predecessor for
telephone circuits and equipment for the nine-month period ended September 30,
1996 was approximately $1,700,000. Rental expense for telephone circuits and
equipment is included in operating costs in the accompanying statements of
operations.

   Rental expense paid to related parties was approximately $35,000 for the
year ended December 31, 1998 and $0 for all other periods presented.

 Purchase Commitments

   At December 31, 1998, the Company had commitments under various contracts
for the purchase of telephone switch equipment. The Company has recorded
$25,597,000 of construction-in-progress in the accompanying balance sheet as of
December 31, 1998, for equipment received prior to year-end but not yet
installed. This amount includes $9,000,000 of purchases that were subsequently
financed through the issuance of additional senior secured borrowings (see Note
3).

                            PAC-WEST TELECOMM, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   In addition, at December 31, 1998, the Company had approximately $52,000,000
of purchase orders outstanding for telephone switching equipment due for
delivery during 1999 and 2000. These purchase orders are cancelable up to 60
days prior to delivery and are expected to be financed from proceeds received
from the senior notes (see Note 11) and from internally generated cash flows.

 Employment Agreements

   The Company has entered into employment agreements with certain key
executives that provide for minimum annual base salaries, bonus entitlements
upon the achievement of certain objectives, and the issuance of stock options.

   These employment agreements, which were approved by the Company's
stockholders in 1998 in connection with the Transaction (see Note 1), granted
options to two executives to purchase up to 568,750 shares of the Company's
common stock. The exercise price of these options of $0.48 per share
approximated the fair market value of the Company's common stock at the date of
grant. These options vest over various dates through October 2001 and expire at
various dates through October 2008.

   The Company accounted for the option grants under APB Opinion No. 25,
"Accounting for Stock Issued to Employees," and accordingly, no compensation
cost has been recognized in the accompanying financial statements as the option
exercise price approximated the estimated fair market value of the stock on the
date of grant.

   Had compensation cost for the options been determined in accordance with
SFAS No. 123, "Accounting for Stock Based Compensation," the Company's pro
forma net loss would have increased $3,000 to $670,000 for the year ended
December 31, 1998. No options were exercisable at December 31, 1998. The
weighted average fair value of options granted during 1998 was $0.06 and the
weighted average contractual life remaining at December 31, 1998 was 9.8 years.

   The fair value of each option grant was estimated on the date of grant using
the Black-Scholes option pricing model, with the following weighted-average
assumptions used for grants during the year ended December 31, 1998: weighted
average risk-free interest rate of 5.0 percent; expected dividend yields of
0 percent; expected lives of two to three years; and expected volatility of 0
percent.

   The employment agreements were effective as of or subsequent to the close of
the Transaction and have terms varying from one to three years; however, they
may be terminated by either party at an earlier date under certain
circumstances. As of December 31, 1998, the Company accrued approximately
$304,000 in accrued payroll and related expenses in the accompanying balance
sheet for bonuses payable under these agreements.

 Revenue Recognition--Billings under Dispute

   The Company has established interconnection agreements with certain
Incumbent Local Exchange Companies (ILECs) in California. The
Telecommunications Act of 1996 requires ILECs to enter into interconnection
agreements with Competitive Local Exchange Companies (CLECs, such as the
Company) and other competitors and requires state Public Utilities Commissions
(PUCs) to arbitrate such agreements.

   The interconnection agreements outline, among other items, compensation
arrangements for calls originating or terminating in the other party's
switching equipment, payment terms, and level of services.

   Two ILECs with which the Company has interconnection agreements have
withheld payments from amounts billed by the Company under their agreements
during the years ended December 31, 1997 and 1998, as follows:

</TABLE>

   The ILECs withheld no payments before August 1997. The first ILEC withheld
payment of 48 percent of the Company's August 1997 billing and continued to
withhold payments monthly, at declining percentages, including a withholding of
20 percent of the December 1997 billing. During 1998, this ILEC withheld an
average of 69 percent of amounts billed. The ILEC has indicated that it has
paid the withheld amounts into an escrow account pursuant to a dispute claim.

   The other ILEC has withheld payments on 100 percent of the monthly amounts
billed by the Company for October 1997 through December 1997 and has withheld
an average of 59 percent of amounts billed during 1998. In 1998, this ILEC paid
$254,000 of amounts previously withheld from 1997 billings. This ILEC has made
no escrow payments.

   Both ILECs have continued to withhold significant percentages of payments
during 1999.

   The issue giving rise to the dispute, based on correspondence with the first
ILEC, relates to the classification of telephone calls entering the Company's
system and terminating to an ISP. Under the interconnection agreements, the
ILECs are obligated to pay the Company for calls originating in the ILECs'
systems and terminating in the Company's system. Local calls are the most
prevalent calls compensated for under the interconnection agreements.

   The first ILEC filed a complaint with the Superior Court of the State of
California that outlined its opinion that Internet traffic calls made to an ISP
are not local calls (but rather interstate calls), and as such are not covered
by the interconnection agreement and are not subject to the jurisdiction of the
PUC. Management understands a similar position was taken by the other ILEC. The
Superior Court ordered this complaint stayed pending the California PUC's
(CPUC's) review of the issues raised by the complaint.

   The first ILEC has requested (without specifying any particular monetary
claims) that the Company refund, with interest, all amounts previously paid to
the Company for Internet traffic calls. All revenues recognized from this ILEC
in the Company's financial statements since the Company's commencement,
including those amounts associated with ISP calls previously paid to the
Company, total $24,998,000, consisting of $10,533,000 and $13,861,000 for the
years ended December 31, 1997 and 1998, respectively. It is not possible for
the Company or for the ILECs (based on the Company's understanding of their
systems) to determine which calls to an ISP telephone number are then
connected, by way of the ISP's equipment, on to the Internet network.
Accordingly, it is not possible to identify amounts specifically billed to or
paid by the ILECs for calls actually connected, by way of the ISP's equipment,
on to the Internet network.

   Management, after consultation with its regulatory attorneys, believes that
calls originated in the ILECs' systems and terminated in the Company's system
at an ISP, including all calls actually connected by way of the

                            PAC-WEST TELECOMM, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

ISP's equipment on to the Internet network, are local calls, and, accordingly,
the Company is entitled to compensation pursuant to its interconnection
agreements with the ILECs. Further, the Company believes decisions and actions
taken by PUCs of various states, including California, support the Company's
position. As a result, no amounts have been accrued for in the Company's
financial statements for any potential refunds of any amounts previously
received from these ILECs. In October 1998, the CPUC issued a decision
supporting the Company's position that local telephone calls placed to ISPs
terminate at the ISP and, therefore, are local calls entitled to reciprocal
compensation. Subsequent to this decision, the ILEC involved in this complaint
filed an Application for Rehearing of the above decision. In addition, in
February 1999, the Federal Communications Commission (FCC) issued a Declaratory
Ruling on the issue of reciprocal compensation for calls bound to ISP's. The
FCC ruled that these calls are jurisdictionally interstate calls. The FCC,
however, determined that this issue did not resolve the question of whether
reciprocal compensation is owed. The FCC noted a number of factors that would
allow the state PUC's to leave their decisions requiring the payment of
compensation undisturbed. The Company cannot predict the impact of the FCC's
ruling on existing state decisions, or the outcome of pending appeals or on
additional cases in this matter. Given the uncertainty concerning the final
outcome of the CPUC proceedings, the possibility of future extended appeals or
additional litigation, and future decisions by the FCC, management continues to
record the revenue associated with reciprocal compensation billings to the two
ILECs discussed above on a cash-received basis.

6. Stockholders' Equity:

 Common Stock

   Pursuant to the Transaction, the stockholders of the Company entered into a
Shareholders' Agreement that provides for, among other things, the election of
certain individuals as Directors of the Company, restrictions on transfers,
rights of first-offer, and participation rights in any shares of Preferred
Stock or common stock. Under this agreement, the Company has agreed not to
issue or sell additional shares of common stock prior to an initial public
offering, unless certain parties to the Shareholders' Agreement are given the
opportunity to subscribe for and purchase their pro rata portion of the
additional shares at the same price and same terms.

   The stockholders of the Company also entered into a Registration Agreement,
whereby at any time prior to September 26, 2001, a certain stockholder may
request the Company grant holders of its common stock the right to purchase a
certain number of shares of the Company's common stock (the Rights Offering).
Within a certain period after the Rights Offering closes, the Company's
stockholders may request that the Company register all or any portion of the
stockholders' common stock in the Company with the Securities and Exchange
Commission (SEC), when the offering value of the Company's securities in an
initial public offering is at least $25,000,000.

 Convertible Redeemable Preferred Stock

   On September 16, 1998, the Company, as discussed in Note 1, amended and
restated its articles of incorporation to allow for the issuance of the
1,750,000 shares of nonvoting $0.001 par value Preferred Stock. The Preferred
Stock has preference over common stock in liquidation equal to the liquidation
value of $25.72 per share, plus accrued dividends computed at a 10 percent
rate, compounded quarterly (the Preference Amount). After payment of the
Preference Amount, the Preferred Stock and the common stock share ratably in
any distribution by the Company. At December 31, 1998, $1,324,000 (or $0.757
per outstanding share of Preferred Stock) is accrued for cumulative preferred
dividends.

   The holders of a majority of the outstanding Preferred Stock have the right
to convert all of the outstanding Preferred Stock into shares of common stock
in connection with the consummation of a public

offering of debt or equity securities or rights to acquire any debt or equity
securities of the Company offered to the public (a Public Offering).
Additionally, any holder of at least 5 percent of the outstanding Preferred
Stock may convert its shares of Preferred Stock to shares of common stock in
connection with a Public Offering. Each share of Preferred Stock will be
convertible into a number of shares of common stock determined by dividing the
Preference Amount by the initial Public Offering price of the common stock.

   The Company is required to redeem at the request of a majority of the
holders in the event of a Public Offering or after December 31, 2003, all of
the Preferred Stock outstanding. In addition, any 5 percent holder may require
the Company to redeem its shares of Preferred Stock with the net proceeds of a
Public Offering at a redemption price equal to 100 percent of the liquidation
preference thereof, plus accumulated and unpaid dividends at the date of
redemption.

   The Predecessor and the Company had loans payable to certain former officers
and a stockholder of the Company. The loans payable bore interest at 9.5

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

repayment terms. Interest expense related to these loans was $4,000 and $7,000,
for the period from commencement (October 1, 1996) to December 31, 1996, and
for the year ended December 31, 1997, respectively. Interest expense related to
these loans was $14,000 for the Predecessor's nine-month period ended September
30, 1996. The principal and related accrued interest were paid in full for all
such loans during 1997.

 Bay Alarm Company (Bay Alarm)

   Bay Alarm (a major stockholder of the Company) and its subsidiary, InReach
Internet, LLC, are collectively one of the Company's largest customers of
telephone network services, comprising approximately $396,000, $2,109,000, and
$2,680,000, or 9.4 percent, 7.1 percent and 6.4 percent of the Company's
revenues for the three-month period from commencement (October 1, 1996) to
December 31, 1996, and for the years ended December 31, 1997 and 1998,
respectively. Revenues from Bay Alarm and InReach Internet LLC comprised
approximately $891,000, or 10.2 percent of the Predecessor's revenues for the
nine-month period ended September 30, 1996.

   The Company also had amounts due from Bay Alarm as of December 31, 1997 and
1998. These amounts are included in accounts receivable from related parties in
the accompanying balance sheets. The Company owed Bay Alarm $850,000 at the
date of commencement (October 1, 1996) related to debt assumed from the Initial
Transfer. This amount was repaid in full by December 31, 1996.

   Bay Alarm provides the Company with security monitoring services at its
normal commercial rates. The Company has recorded $10,000, $48,000 and $58,000
as selling, general and administrative expense for these services for the
three-month period from commencement (October 1, 1996) to December 31, 1996,
and for the years ended December 31, 1997 and 1998, respectively. The
Predecessor recorded approximately $11,000 as selling, general and
administrative expense for services received from Bay Alarm for the nine-month
period ended September 30, 1996.

   As outlined in Note 5, Leases, the company began leasing its facility in
Oakland from Bay Alarm during 1998. In addition to rent paid under this lease,
the company recorded selling, general and administrative expense of $59,000 for
the year ended 1998 for related utility charges.

 Notes Receivable from Stockholders

   In 1998, in connection with the Transaction, a stockholder of the Company,
who is also an officer, purchased 525,000 shares of common stock from the
Company for $250,000. The Company received $50,000 in cash from the stockholder
and entered into a note receivable for the remaining balance of $200,000.
Subsequent to the Transaction, another officer of the Company acquired 87,458
shares of common stock for $42,000. The Company received $9,000 in cash and
entered into a note receivable for the remaining $33,000 due from the officer.
The notes accrue interest at 5.54 percent and 5.12 percent, respectively,
compounded annually, with any unpaid accrued interest and principal due at the
earlier of (1) the sale of the above stock with proceeds received first applied
to unpaid interest, then to principal; (2) sale of the Company; (3) 60 days
from the date the stockholder is no longer an employee of the Company or a
subsidiary; or (4) September 16, 2003 and October 16, 2003, respectively.

9. Retirement Plan:

   In October 1996, the Company adopted a 401(k) retirement plan (the Plan) for
all full-time employees who have completed six months of service. The plan year
is from January 1 to December 31, and the Company will contribute $0.50 for
every $1.00 contributed by the employee, subject to the Company's contribution
not

exceeding 3 percent of the employee's salary. Participants become fully vested
after six years of service, although they vest incrementally on an annual basis
after two years of service and until the six-year period is completed. The
Company recorded selling, general and administrative expense of $63,000 and
$58,000 for the years ended December 31, 1997 and 1998, respectively, for the
Company's matching contributions.

   Employees of the Company previously contributing to the CalPage 401(k)
retirement plan (with identical provisions to the Plan) were able to roll their
accumulated benefits into the Plan at date of commencement (October 1, 1996),
with all prior employer contributions becoming fully vested on the date of
rollover.

10. Sale of Answering Service Division:

   In March 1997, the Company sold the customer base and other assets of its
answering service division for $420,000, payable $200,000 in cash and a
promissory note of $220,000. The promissory note was paid in October 1997 at a
discount of $18,000. The Company recognized a net gain of $385,000 on the sale
in the year ended December 31, 1997.

11. Subsequent Events:

   On January 29, 1999, the Company issued $150,000,000 of senior unsecured
ten-year notes (the Senior Notes) at par. The Senior Notes bear interest at
13.5 percent payable in semiannual installments, with principal due on February
1, 2009.

   Proceeds of the Senior Notes were used to repay the senior secured
borrowings (see Note 3) and to establish an interest reserve account to cover
certain initial interest payments due under the Senior Notes.

   The Senior Notes carry provisions that allow the Company, at its option, to
(i) redeem up to 35 percent of the notes with proceeds of certain public
offerings of equity prior to February 1, 2002, (ii) redeem all or part of the
notes at specified prices on or after February 1, 2004, or (iii) offer to
exchange the notes within 180 days from the issue date for a new issue of
identical debt securities registered under the Securities Act of 1933, as
amended (the Securities Act). The Company intends to register these notes under
the Securities Act during the first six months of 1999.

   Basic covenants of these notes restrict the Company's future ability to pay
dividends, repurchase stock, pledge or sell assets as security for other
transactions, or engage in mergers and business combinations. The covenants
allow the Company to incur additional debt subject to various limitations.

   In January 1999, the Company's Board of Directors approved the terms of the
1999 Employee Stock Option Plan (the 1999 Stock Plan) pursuant to which
qualified employees and members of the Board of Directors can be issued options
to purchase the Company's common stock at the fair market value at the date of
grant. An aggregate of 3,150,000 shares of common stock have been reserved for
option grants under the 1999 Stock Plan.

12. Ten-for-One Stock Split:

   On March 19, 1999, the board of directors authorized a ten-for-one split of
the Company's authorized and outstanding common stock and Preferred Stock. All
share and per share data have been restated to reflect the ten-for-one split.

13. 1.4-for-1 Stock Split:

   On October 7, 1999, the board of directors authorized a 1.4-for-1 split of
the Company's outstanding common stock and Preferred Stock. All share and per
share data have been restated to reflect the 1.4-for-1 split. In addition, on
October 7, 1999, the board of directors approved a resolution to increase the
authorized shares of common stock to 50,000,000 shares.

      Total....................................................... $150,062,000
                                                                   ============
</TABLE>

   On January 29, 1999, the Company issued $150,000,000 of Senior Notes at par.
The Senior Notes bear interest at 13.5 percent payable in semiannual
installments, with principal due on February 1, 2009.

   Proceeds of the Senior Notes were used to repay $100,000,000 of senior
secured borrowings (including $9,000,000 of other long-term obligations
subsequently financed through senior secured borrowings) and to establish an
interest reserve account to cover interest payments due under the Senior Notes
through February 1, 2000.

   The Senior Notes carry provisions that allow the Company, at its option, to
(i) redeem up to 35 percent of the notes with proceeds of certain public
offerings of equity prior to February 1, 2002, (ii) redeem all or part of the
notes at specified prices on or after February 1, 2004, or (iii) offer to
exchange the notes within 180 days from the issue date for a new issue of
identical debt securities registered under the Securities Act of 1933, as
amended (the Securities Act). The Company is in the process of registering
these notes under the Securities Act.

   Basic covenants of these notes restrict the Company's future ability to pay
dividends, repurchase stock, pledge or sell assets as security for other
transactions, or engage in mergers and business combinations. The covenants
allow the Company to incur additional debt subject to various limitations.

   The Company has a three-year senior credit facility that provides for
maximum borrowings of $40.0 million to finance working capital, the cost of the
Company's planned capital expansion and other corporate transactions. The
borrowings are secured by substantially all of the Company's assets. Borrowings
under this senior credit facility bear interest, at the Company's option, at
(1) the Base Rate (as defined) or (2) the LIBOR rate plus between 2.25% and
3.5%. As of June 30, 1999, there were no amounts outstanding under this
facility and the borrowing rate would have been approximately 8%. The credit
facility requires the Company to meet certain financial tests, including,
without limitation, maximum levels of debt as a ratio of EBITDA (as defined),
minimum interest coverage and maximum amount of capital expenditures. The
credit facility contains certain covenants which, among other things, limit the
incurrence of additional indebtedness, investments, dividends, transactions
with affiliates, asset sales, acquisitions, mergers and consolidations,
prepayments of other indebtedness (including the Senior Notes), liens and
encumbrances and other matters customarily restricted in such agreements.

7. Purchase Commitments:

   At June 30, 1999, the Company had approximately $38,000,000 of purchase
orders outstanding for network equipment due for delivery during 1999 and 2000.
These purchase orders are cancelable without penalty up to 60 days prior to
delivery and are expected to be financed from proceeds received from the Senior
Notes (see Note 6) and from internally generated cash flows.

   In addition, the Company is in the process of implementing a new billing and
operations support system. Total estimated costs for this system aggregate
approximately $15,000,000 of which approximately $7,500,000 is estimated to be
incurred in 1999, $6,000,000 in 2000, and $1,500,000 in 2001. Of the estimated
$7,500,000 costs to be incurred in 1999, $2,700,000 is recorded in projects-in-
progress at June 30, 1999.

8. Revenue Recognition:

   Service revenues are recognized in the month in which the service is
provided, except for reciprocal compensation generated by calls placed to
Internet service providers connected through the Company's network. The rights
of CLECs (such as the Company) to receive this type of compensation is the
subject of numerous regulatory and legal challenges (see Note 12). Until this
issue is ultimately resolved, the Company will recognize this revenue on a
cash-received basis.

   The two ILECs with which the Company has interconnection agreements have
withheld payments from amounts billed by the Company under their agreements
since August 1997. Amounts withheld during the six month periods ended June 30,
1998 and 1999 are as follows:

the Company's authorized and outstanding common stock and Preferred Stock.

   On October 7, 1999, the board of directors authorized a 1.4-for-1 split of
the Company's outstanding common and Preferred Stock. In addition, on October
7, 1999, the board of directors approved a resolution to increase the
authorized shares of common stock to 50,000,000 shares. All share and per share

1999, $3,649,000 (or $2.085 per outstanding share of Preferred Stock) is
accrued for cumulative preferred dividends.

 Stock Options

   In January 1999, the Company's Board of Directors approved the terms of the
1999 Stock Incentive Plan (the Plan) which authorizes the granting of stock
options, including restricted stock, stock appreciation rights, dividend
equivalent rights, performance units, performance shares or other similar
rights or benefits to employees, directors, consultants and advisors. Options
granted under the Plan have a term of ten years.

   An aggregate of 3,150,000 shares of common stock have been reserved for
option grants. Options to purchase 873,250 shares of common stock were granted
and options to purchase 13,300 shares of common stock were canceled during the
six month period ended June 30, 1999.

   The following table summarizes information about the Company's stock options
outstanding as of June 30, 1999:

10. Income (Loss) Per Share:

   Diluted income (loss) per share information is presented in the accompanying
statements of income as being the same as basic income (loss) per share
information since the impact of the issuance of potential common shares from
the exercise of common stock options is antidilutive.

11. Comprehensive Income:

   In September 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income". SFAS No. 130 establishes reporting and disclosure requirements for
comprehensive income and its components within the financial statements. There
were no items of other comprehensive income for the six month periods ended
June, 1998 and 1999; therefore comprehensive income is the same as net income
for both periods.

12. Legal Proceedings:

   The Company is a party to the Pacific Bell and California Public Utility
Commission proceedings related to reciprocal compensation payment and other
interconnection agreement issues. See Note 8 to these condensed financial
statements and the Company's 1998 audited financial statements.

   On June 24, 1999, the California Public Utilities Commission adopted a
decision in the arbitration proceeding between the Company and Pacific Bell
which held that reciprocal compensation would be payable for Internet service
provider calls under the new interconnection agreement with Pacific Bell, which
became

                                      F-31

                            PAC-WEST TELECOMM, INC.

          NOTES TO INTERIM CONDENSED FINANCIAL STATEMENTS--(Continued)

                                  (Unaudited)

effective on June 29, 1999. Pacific Bell has requested a rehearing of this
decision, although Pacific Bell has paid the full amount of billings for calls
since the effective date of the new agreement. This decision does not address
reciprocal compensation withheld under the prior agreement and management does
not know at this time what action Pacific Bell will take with respect to the
amounts they have previously withheld.

   On September 9, 1999, the Company entered into a settlement agreement with
Pacific Bell regarding its claims for unpaid reciprocal compensation under
their prior interconnection agreement. Under the terms of the settlement
agreement, Pacific Bell agreed to pay $20.0 million to the Company and $20.0
million to certain stockholders of the Company as of the date of the
recapitalization in settlement of those claims. As a result of these payments,
the terms of our September 1998 recapitalization requiring additional
distributions to certain of our shareholders have been satisfied.

   Subsequent to September 30, 1999, GTE paid, and the Company recorded as
revenue, $6,308,000 of reciprocal compensation that GTE had previously
withheld. GTE has not waived its rights to appeal, contest or seek subsequent
reimbursements of amounts paid by it as reciprocal compensation.

13. Segment Reporting:

   The Company has adopted Statement of Financial Accounting Standards (SFAS)
No. 131, "Disclosures about Segments of an Enterprise and Related Information".
As an integrated telecommunications provider, the Company has one reportable
operating segment. While the Company's chief decision-maker monitors the
revenue streams of various services, operations are managed and financial
performance is evaluated based upon the delivery of multiple services over
common networks and facilities. This allows the Company to leverage its costs
in an effort to maximize return. As a result, there are many shared expenses
generated by the various revenue streams; because management believes that any
allocation of the expenses to multiple revenue streams would be impractical and
arbitrary, management does not currently make such allocations internally. The
chief decision-maker does however, monitor revenue streams at a more detailed
level than those depicted in the Company's historical general purpose financial
statements.

   Specifically, the following table presents revenues by service type:
