This is the initial public offering of shares of common stock of Pac-West

shareholders. We will not receive any proceeds from the shares being offered by

                               PROSPECTUS SUMMARY

   The following summary highlights selected information in this prospectus.
The summary may not contain all of the information that is important to you.
This prospectus includes forward-looking statements which involve risks and
uncertainties. You should carefully read the entire prospectus, including the
risk factors and the financial statements, before deciding whether to invest in
our common stock.

                            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,
medium and small 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 eight 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 medium and small business customers. These customers want technologically
advanced communication solutions from a single source. Our complete product
offering of system design, equipment selection and installation, and bundled
local, long distance and data services directly meets the needs of this under-
served market. Our focus on medium and small 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 medium and small 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 medium and small business market. We believe that most
    medium and small 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 throughout our coverage area.

    . Remote access services, including mobile or remote office, virtual
      office, distance education 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.

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 "As Adjusted" summary balance sheet data reflects the sale of the
shares of common stock offered by us in this offering at an assumed initial
public offering price of $        per share, after deducting the underwriting
discount and estimated offering expenses payable by us, and the conversion of
our outstanding convertible redeemable preferred stock into     shares of
common stock at an assumed conversion price of $   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.

   We recognize reciprocal compensation as revenue only to the extent received
in cash. Pacific Bell and GTE, two incumbent local exchange carriers with which
we have interconnection agreements, have each refused to pay us the portion of
reciprocal compensation 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.

                                  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

                                       7
<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, have refused to pay that portion of
compensation under the agreement that they estimate is the result of inbound
calls terminating to Internet service providers, and the obligation to pay this
reciprocal compensation 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. 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, but did not determine whether Pacific Bell owes reciprocal
compensation withheld under the prior agreement. Pacific Bell has requested a
rehearing of this matter. 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 and otherwise contest the claims of GTE California. 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.

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.

                                       8
<PAGE>

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.

   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.

                                       9
<PAGE>

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 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,

                                       10
<PAGE>

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.

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

                                       11
<PAGE>

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."

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     shares of common stock at an assumed
conversion price of $   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 own
approximately   % of our common stock. Following consummation of this offering
and assuming all        shares offered pursuant to the directed share
subscription program are purchased by shareholders of Safeguard Scientifics,
these investors will own   % 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     % 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."

                                       12
<PAGE>

   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.
We intend to have our common stock approved for quotation on the Nasdaq
National Market. We do not know how our common stock will trade in the future.
The initial public offering price will be 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.


                                       13

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
$        less than the assumed $        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 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."

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 $       , or approximately
$        if the underwriters' over-allotment option is exercised in full. These
estimates are based on an assumed initial public offering price of $        per
share and 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           shares and Safeguard
Scientifics is offering           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 has agreed that Safeguard
Scientifics or one or more of its designees will purchase these shares from us
at the closing of this 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    shares of common stock at an
assumed conversion price of $   per share, Safeguard Scientifics beneficially
owned     shares or approximately   % of our common stock. After this offering,
Safeguard Scientifics will beneficially own            shares or approximately
    % 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      shares
or approximately     % 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.

                                 CAPITALIZATION

   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         shares of
    common stock offered by us in this offering at an assumed initial public
    offering price of $       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    shares of common stock at an assumed conversion price of $   per
    share.

   This table should be read in conjunction with the sections entitled "Use of

                                    DILUTION

   Our net tangible book value (deficit) as of June 30, 1999 was $(75,634,000)
or $    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.

   After giving effect to adjustments relating to the offering, our unaudited
pro forma net tangible book value as of June 30, 1999, would have been $    or
$    per share. The adjustments made to determine pro forma 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" assuming that the initial
    public offering price will be $   per share.

  . The addition of the number of shares offered by this prospectus to the
    number of common shares outstanding and the conversion of all outstanding
    shares of our convertible redeemable preferred stock into common stock.

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

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

  .     shares of common stock issuable upon the exercise of outstanding
    options with a weighted average exercise price of $   per share; and

  .     shares of common stock issuable upon the exercise of options reserved
    for grant under our stock option plans,

   In addition, the calculations above assume all    shares offered pursuant to
the directed share subscription program are purchased by the shareholders of
Safeguard Scientifics.

   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.

   The "As Adjusted" selected balance sheet data reflects the sale of the
        shares of common stock offered by us in this offering at an assumed
initial public offering price of $       per share, after deducting the
underwriting discount and estimated offering expenses payable by us, and the
conversion of our outstanding convertible redeemable preferred stock into
shares of common stock at an assumed conversion price of $    per share.

   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.

   We recognize reciprocal compensation as revenue only to the extent received
in cash. Pacific Bell and GTE, two incumbent local exchange carriers with which
we have interconnection agreements, have each refused to pay the portion of
reciprocal compensation 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,
medium and small 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 medium and small 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 another carrier,
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. Two incumbent local exchange carriers
with which we have interconnection agreements, Pacific Bell and GTE, have
refused to pay that portion of reciprocal compensation that they estimate is
the result of inbound calls terminating to Internet service providers. These
incumbent local exchange carriers contend that such Internet service provider
calls are not local calls within the meaning of their respective
interconnection agreements and claim that no reciprocal compensation is
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 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 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. This decision does not address
reciprocal compensation withheld under the prior agreement. We do not know at
this time what action Pacific Bell will take with respect to the amounts they
have previously withheld. On August 25, 1999, we, along with the commissioners
of the California Public Utility Commission 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 and otherwise contest the claims of GTE California. In the event that
all or a portion of the withheld reciprocal

                                       22
<PAGE>

compensation is paid by either Pacific Bell or GTE, the terms of our
recapitalization require us to pay additional distributions to certain owners
of up to $20.0 million. In 1999, the maximum cash distribution under the terms
of the recapitalization could be up to approximately $15 million, net of the
after tax proceeds from the withheld reciprocal compensation. 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

                                       23

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 the increased utilization of this newly installed switch
capacity, primarily attributable to Internet service provider customers. In
addition, new service orders from medium and small businesses have accelerated
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 from 1998 to 1999, from 28,108 lines in service by Internet service
providers at June 30, 1998 to 60,401 lines in service at June 30, 1999.

   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 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.

                                       24
<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. Total employees almost doubled 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 medium and small
businesses.

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

                                       25
<PAGE>

   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% 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.

                                       26
<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 were $75,000 and $1,092,000, respectively.

                                       27
<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 initial maximum borrowings of $20.0
million and future borrowings of up to an additional $20.0 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%.

                                       28
<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.

                                       30
<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,
medium and small 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 medium and small 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 medium and small 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 medium and small
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 cover 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 medium
and small 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 eight 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. Medium and small
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 medium and
small 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, medium and small 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. 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 and

                                       34
<PAGE>

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 eight 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 medium and small 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 medium and small business market. We believe that medium and
small 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
medium and small businesses by offering a complete product offering of system
design, equipment selection and installation along with bundled local and long
distance services. 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.

   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
    throughout our coverage area.

  . Remote access services, including mobile or remote office, virtual
    office, distance education and training, and telecommuting. These
    services 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 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.

   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, medium and small 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.

                                       38
<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 medium and small business customers include regional banks, alarm
companies, universities, healthcare providers, real estate agencies, law firms
and others.

   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 service 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, 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.

                                       39
<PAGE>

   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.

                                       40
<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

                                       41
<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.

   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.

     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.

                                       42
<PAGE>

     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 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.

                                       43
<PAGE>

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 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

                                       44
<PAGE>

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 states have issued decisions either initially or on
reconsideration of existing decisions. In nineteen 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 is
the only state 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 and Colorado, an application is pending
in Arizona, and we intend to file applications for such authority in the near
future for Idaho, Utah, New Mexico and Texas. 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 terminate at the Internet service providers' modem and are thus 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 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.

                                       45
<PAGE>

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 Pacific Bell
and 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. This petition proposed
that telephone calls to Internet service providers be excluded from calls
subject to reciprocal compensation. This petition also proposed that calls made
to a number assigned to the calling party's rate center but routed to a second
rate center be deemed interexchange toll-free calls for which Pacific Bell
would be entitled to compensation for providing switched access. Pacific Bell
asserts that, because such calls would allow certain calling parties to
complete calls to Internet service providers or other customers in another rate
center without toll charges, these calls are essentially toll-free in nature. A
previous decision of general application issued by the California Public
Utilities Commission in October of 1998 held that calls to Internet service
providers are subject to the payment of reciprocal compensation. We have
asserted that because calls routed to a second rate center are placed by
dialing a number assigned to the calling party's rate center and not using 8XX
toll-free processing that these calls should not be considered toll-free. 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 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, and that Pacific Bell's position concerning toll free
calls was rejected. 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 although they did pay the full amount of
our billings for calls after the effective date of the new agreement. The
California Public Utilities Commission decision does not address reciprocal
compensation withheld under the prior agreement and we do not know at this time
what action Pacific Bell will take with respect to the amounts previously
withheld.

   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

                                       46
<PAGE>

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 July 6, 1999, an administrative law judge released a draft
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 draft decision defers the
resolution of intercarrier compensation issues in such circumstances to further
evidentiary proceedings. After receiving comments, the California Public
Utilities Commission will vote on the draft decision. 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."

 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 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.

 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 of the incumbent local exchange carriers with which we
have interconnection agreements, Pacific Bell and GTE, have refused to pay that
portion of reciprocal compensation that they estimate is 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

                                       47
<PAGE>

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. These motions are currently pending. 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 Pacific Bell 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, 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 and 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 Pacific Bell 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 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 states have issued
decisions either initially or on reconsideration of existing decisions. In
nineteen 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 is 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
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 dismissed Ameritech's appeal of the Wisconsin Public Utilities
Commission's order on the grounds that the Commission was 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

                                       48
<PAGE>

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 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 continuing
propriety of Pac-West's service methods. 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 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 customers using this method. A prohibition on this service would impair our
ability to provide service to our customers. We presently claim reciprocal
compensation based on these calls. A California Public Utilities Commission
holding that such calls are not entitled to reciprocal compensation could
result in a significant loss of revenue to us.

 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 issues:

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

   (2) reciprocal compensation rates; and

   (3) term of the agreement.

   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 June 24, 1999,
the California Public Utilities Commission adopted a decision in the
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 requested a rehearing of this matter although they did
pay the full amount of our billings for calls after the effective date of the
new agreement. This decision does not address reciprocal compensation withheld
under the prior agreement. We do not know at this time what other action
Pacific Bell will take with respect to the amounts they have previously
withheld. If the California Public Utilities Commission ultimately determines
that such calls are not entitled to reciprocal compensation, such a
determination could result in a significant loss of revenue to us and an
obligation to pay significant amounts to Pacific Bell.

                                       49
<PAGE>

   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 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 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.

                                       50

   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.

   The present principal occupations and recent employment history of each of
our executive officers, key employees and directors listed above are set forth
below.

   Wallace W. Griffin has served as the President, Chief Executive Officer and
a Director of Pac-West since September 1998. From 1994 to 1997, Mr. Griffin
served as a Group President for a number of Jones International companies,
including Jones Lightwave, Ltd., a competitive local exchange carrier, and
Jones Education Company, a leader in using technology to deliver education.
Concurrently, he was co-owner of a consulting and business development company,
Griffin Enterprises, Inc. From 1987 through 1992, Mr. Griffin served as the
President and Chief Executive Officer of U S West Marketing Resources Group,
where he managed the $1 billion publishing, media software and advertising
services division. Mr. Griffin has over thirty-five years experience in
telecommunications, cable television, publishing and advertising.

   John K. La Rue founded Pac-West's predecessor, also known as Pac-West
Telecomm, Inc., in 1980 and served as its President from 1980 until September
30, 1996 and as our President from our incorporation in 1996 until September
1998. Since September 1998, Mr. La Rue has served as our Executive Vice
President of Technology and Network Operations and as a Director.

   Richard E. Bryson has served as our Chief Financial Officer since November
1998. From 1992 to 1998, Mr. Bryson worked at Bank of America as a Managing

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
2,250,000 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. In 1999, options to purchase 335,000
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 1,020,500 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.

   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 375,000 shares of common stock for an aggregate purchase price of
$250,000 and Mr. Bryson purchased 62,470 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 250,000 shares and 156,250 shares, respectively, of common
stock at a purchase price of $0.67 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

                                       57
<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,
80,395 shares of convertible redeemable preferred stock and 763,800 shares of
common stock and Bay Alarm Company received $57.4 million in cash, 285,038
shares of convertible redeemable preferred stock and 2,707,900 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.

                                       59
<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. In 1999, the maximum cash
distribution under the terms of the recapitalization could be up to
approximately $15 million, net of the after tax proceeds from the withheld
reciprocal compensation.

   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 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

                                       61
<PAGE>

ourselves, the underwriters and the selling stockholders. After the earlier of
180 days after the consummation of the rights 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,
Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah and Washington, the
province of British Columbia, Canada and the territories and jurisdictions of
Mexico. For purposes of Mr. Griffin's and Mr. Bryson's respective agreements,
the restricted territories include the United States of America, Canada and the
territories and jurisdictions of Mexico.

   Messrs. La Rue, Griffin, Bryson, Meyer, Mills and Bay Alarm have also agreed
to maintain the confidentiality of our information and not to solicit our
employees and customers as provided in the merger agreement or their respective
employment agreements, as the case may be.

recapitalization and as a director of the Board since the recapitalization, is

dated November 23, 1998, and after giving effect to our ten for one stock

We and Mr. La Rue retain the right to repurchase this stock upon the
termination of Mr. Mills' employment with Pac-West for any reason. Upon
repurchase, the purchase price of Mr. Mills' stock will be at fair market value
unless he is terminated with cause, in which case the purchase price will be
the lesser of original cost or fair market value.

Selling Shareholder

   Safeguard Scientifics may sell up to           shares of our common stock to

Assuming that all the shares offered in the directed share subscription program
are purchased by shareholders of Safeguard Scientifics and the conversion of
our outstanding convertible redeemable preferred stock into     shares of
common stock at an assumed conversion price of $   per share, Safeguard

stock after completion of this offering. If the shareholders of Safeguard
Scientifics do not purchase any of the shares offered in the directed share
subscription program and Safeguard Scientific purchases all of the shares

                          DESCRIPTION OF CAPITAL STOCK

General Matters

   Immediately prior to the offering, the total amount of our authorized
capital stock will consist of 15,000,000 shares of common stock, par value
$0.001 per share, and 1,750,000 shares of convertible redeemable preferred
stock, par value $0.001 per share. Upon completion of the offering, all
1,250,000 shares of convertible redeemable preferred stock outstanding will be
converted into common stock and         shares of common stock will be issued
and outstanding. The discussion below describes our capital stock, the articles
of incorporation and by-laws as anticipated to be in effect upon consummation
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.

   We have applied to have our common stock 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, $36, plus an amount
which accrues on a daily basis at a rate of 10% per annum on the original cost
of such shares, $36, 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 consummation 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 consummation 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.

                                       67
<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:

Limitations on Liability and Indemnification of Officers and Directors

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

reasonably incurred in connection with any proceeding arising by reason of the

                          DESCRIPTION OF INDEBTEDNESS

Senior Credit Facility

   Our senior credit facility provides for initial borrowings of $20.0 million
and future borrowings from time to time of up to an additional $20.0 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

                                       69
<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:

</TABLE>

 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

   Immediately following this offering, there will be            shares of our
common stock issued and outstanding. Of these shares, the            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
           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. Prior to the date of
this prospectus, no public market has existed for our common stock. We expect
that trading of our common stock on the Nasdaq National Market will commence on
the date of this prospectus. 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 some of our shareholders, who
collectively hold            of the outstanding shares of our common stock,
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.

Registration Statement on Form S-8

   Following this offering, we intend to file a registration statement on Form
S-8 under the Securities Act to register the shares of common stock reserved
for issuance under our employee benefit plans. The stock registered under that
registration statement will thereafter be available for sale in the public
market, subject to the resale limitations of Rule 144 applicable to our
affiliates.

                                  UNDERWRITING

   Of the     shares of our common stock offered by this prospectus, we are
offering     shares to the public generally in an underwritten public offering
and     shares to the shareholders of one of our shareholders, Safeguard
Scientifics, and Safeguard Scientifics is offering up to     shares, in a
directed share subscription program.

   Subject to the terms and conditions set forth in an underwriting agreement
dated           , 1999, each of the underwriters named below, through their
representatives Bear, Stearns & Co. Inc., Banc of America Securities LLC, and
First Union Capital Markets Corp., has severally agreed to purchase from us the
aggregate number of shares of common stock set forth opposite its name below at
the public offering price less the underwriting discount set forth on the cover
page of this prospectus. The           shares of common stock being purchased
by the underwriters does not include the         shares of common stock being
offered by us and the           shares of our common stock being offered by

</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 $      per share. The underwriters may allow, and dealers may re-allow,
concessions not in excess of $      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.

   We have granted the underwriters an option exercisable for 30 days from the
date of the underwriting agreement to purchase up to         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

                                       72
<PAGE>

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 and executive officers and some of our shareholders, who
collectively hold a total of       shares of common stock, 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.

   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.

   We have applied to have our common stock 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.

   The underwriters have reserved for sale, at the initial public offering
price, up to        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.

our convertible redeemable preferred stock and 1.8% of our common stock, which

of America Securities LLC and First Union Capital Markets Corp. also own a

transactions with, and perform services for, us in the ordinary course of their
business.

                      Directed Share Subscription Program

   As part of this offering, we are offering           shares and Safeguard
Scientifics is offering up to           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. The underwriters are not
purchasing the shares in the directed share subscription program, and are not
an "underwriter" with respect to those shares.

   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 has agreed that Safeguard
Scientifics or one or more of its designees will purchase these shares from us
at the closing of this offering. Although these shares were 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, subject to limited
exceptions, not to offer, sell or otherwise dispose of any shares of our common
stock, including shares purchased by it in the directed share subscription
program, for a period of 180 days after the date of this prospectus other than
in connection with this offering. Sales under the directed share subscription
program will close on 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, 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, assuming conversion of our outstanding convertible
redeemable preferred stock into     shares of common stock at an assumed
conversion price of $   per share, Safeguard Scientifics

                                       74
<PAGE>

beneficially owned      shares or approximately     % of our common stock.
After this offering, Safeguard Scientifics will beneficially own
shares or approximately     % 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      shares or approximately     % 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 $          or an amount equal to   % 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 $           or
an amount equal to   % 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 by us to Bear, Stearns & Co. Inc. and the proceeds,

                    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

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.

 Merger and Recapitalization

   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)


   The largest supplier is also the largest ILEC, as shown above in the
concentration of revenues. See Note 8 for revenues from related parties.

 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.

 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 conversion of preferred stock
and 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).

   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).

                   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 406,250 shares of the Company's
common stock. The exercise price of these options of $0.67 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 $0.09 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

</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 $36 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 $1.059 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 provision for income taxes for the nine-month period of the Predecessor
has been calculated using the Company's overall effective tax rate for the
period from commencement (October 1, 1996) to December 31, 1996. In conjunction
with the Initial Transfer, CalPage assumed various liabilities of the
Predecessor including deferred taxes of $280,000 at September 30, 1996.

8. Related-Party Transactions:

 Loans Payable to Officers and Stockholder

   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
percent to 10.0 percent and did not contain specified

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 375,000 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 62,470
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 2,250,000 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.

</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
initial borrowings of $20.0 million and future borrowings of up to an
additional $20.0 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:

9. Stockholders' Equity:

 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.

 Convertible Redeemable Preferred Stock

1999, $3,649,000 (or $2.919 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 2,250,000 shares of common stock have been reserved for
option grants. Options to purchase 623,750 shares of common stock were granted
and options to purchase 9,500 shares of common stock were canceled during the
six month period ended 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 conversion of preferred stock and 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

          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.

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:

Item 14. Indemnification of Directors and Officers.

   We are incorporated under the laws of the State of California. Section 317
of the General Corporation Law of the State of California provides that a
California corporation may indemnify any person who is, or is threatened to be
made, party to any proceeding (other than an action by or in the right of the
corporation to procure a judgment in its favor) by reason of the fact that the
person is or was an agent of the corporation, against expenses, judgments,
fines, settlements, and other amounts actually and reasonably incurred in
connection with the proceeding if that person acted in good faith and in a
manner the person reasonably believed to be in the best interests of the
corporation and, in the case of a criminal proceeding, had no reasonable cause
to believe the conduct of the person was unlawful. A corporation has power to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending, or completed action by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that the
person is or was an agent of the corporation, against expenses actually and
reasonably incurred by that person in connection with the defense or settlement
of the action if the person acted in good faith, in a manner the person
believed to be in the best interests of the corporation and its shareholders.

   Under Article IV of our Amended and Restated Articles of Incorporation and
Article VI of our Amended and Restated By-Laws, we will indemnify each person
who was or is made a party or is threatened to be made a party to or is
involved in any action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he or she, is or
was a director or officer, of Pac-West or is or was serving at the request of
Pac-West as a director, officer, employee, fiduciary, or agent of another
corporation or of a partnership, joint venture, trust or other enterprise
including service with respect to employee benefit plans, whether the basis of
such action, suit or proceeding is alleged action in an official capacity as a
director, officer, employee, fiduciary or agent or in any other capacity while
serving as a director, officer, employee, fiduciary or agent, to the fullest
extent which we are empowered to do so by the General Corporation Law of the
State of California, as the same exists or may hereafter be amended against all
expense, liability and loss including attorneys' fees actually and reasonably
incurred by such person in connection with such action, suit or proceeding. We
may, by action of our board of directors, provide indemnification to our
employees and agents with the same scope and effect as the foregoing
indemnification of directors and officers. Such right of indemnification will
be a contract right and will not be exclusive of any other right which such
directors, officers or representatives may have or hereafter acquire under any
statute, our Certificate of Incorporation, our By-Laws, agreement, vote of
stockholders or disinterested directors or otherwise.


                                      II-1
<PAGE>

   In addition, Section 204 of the General Corporation Law of the State of
California allows a corporation to eliminate the personal liability of a
director of a corporation to the corporation or to any of its stockholders for
monetary damages for a breach of fiduciary duty as a director, provided,
however, that:

   (A) such a provision may not eliminate or limit the liability of directors:

    (1) for acts or omissions that involve intentional misconduct or a
        knowing and culpable violation of law;

    (2) for acts or omissions that a director believes to be contrary to
        the best interests of the corporation or its shareholders or that
        involve the absence of good faith on the part of the director;

    (3) for any transaction from which a director derived an improper
        personal benefit;

    (4) for acts or omissions that show a reckless disregard for the
        director's duty to the corporation or its shareholders in
        circumstances in which the director was aware, or should have been
        aware, in the ordinary course of performing a director's duties, of
        a risk of serious injury to the corporation or its shareholders;

    (5) for acts or omissions that constitute an unexcused pattern of
        inattention that amounts to an abdication of the director's duty to
        the corporation or its shareholders,

    (6) under Section 310, or (7) under Section 316;

   (B) no such provision will eliminate or limit the liability of a director
for any act or omission occurring prior to the date when the provision becomes
effective; and

   (C) no such provision will eliminate or limit the liability of an officer
for any act or omission as an officer, notwithstanding that the officer is also
a director or that his or her actions, if negligent or improper, have been
ratified by the directors.

   Article IV of our Amended and Restated Articles of Incorporation includes a
provision which eliminates directors' personal liability to the full extent
permitted under the General Corporation Law of the State of California.

   We maintain a policy of directors and officers liability insurance covering
certain liabilities incurred by our directors and officers in connection with
the performance of their duties.

Item 15. Recent Sales of Unregistered Securities.

   Pac-West has issued securities in the following transactions, each of which,

  (b) Financial Statement Schedules.

     The following financial statement schedules are included in this
  registration statement:

         Schedule II--Valuation and Qualifying Accounts

   All other schedules for which the provision is made in the applicable
accounting regulations of the SEC are not required under the related
instructions, are inapplicable or not material, or the information called for
thereby is otherwise included in the financial statements and therefore has
been omitted.

Item 17. Undertakings.

    (a) The undersigned registrant hereby undertakes:

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

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

    (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of Pac-West
pursuant to the foregoing provisions, or otherwise, we have been advised that
in the opinion of the SEC such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by us of expenses incurred or paid by a director, officer or
controlling person of Pac-West in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, we will, unless in the opinion
of our counsel the matter has been settled by controlling precedent, submit to
a court of appropriate jurisdiction the question whether such indemnification
by us is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                            ON SUPPLEMENTAL SCHEDULE

   We have audited in accordance with generally accepted auditing standards,
the financial statements of Pac-West Telecomm, Inc. included in this
registration statement and have issued our report thereon dated February 10,
1999 except with respect to Note 12 for which the date is March 19, 1999. Our
audits were made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The accompanying Schedule II--Valuation and
Qualifying Accounts is the responsibility of the company's management and is
presented for purposes of complying with the Securities and Exchange
Commission's rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audits of
the basic financial statements and, in our opinion, fairly states in all
material respects the financial data required to be set forth therein in
relation to the basic financial statements taken as a whole.

Loan and Security Agreement

          (f)  Loan Request Irrevocable. Any Loan Request made pursuant to
               ------------------------
Section 2.2(b) shall be irrevocable and Borrower shall be bound to borrow the
- --------------
funds requested therein in accordance therewith.

     2.3  Making of Revolving Loans.
          -------------------------

          (a)  Lender Advances. Provided that Agent is satisfied in its
               ---------------
discretion with Borrower's Loan Request and the representations and warranties
contained therein, Agent shall forward to each Lender such Loan Request not
later than 1:00 p.m. (San Francisco time) one (1) Business Day after the date of
Agent's receipt of a Loan Request for a LIBOR Loan, or not later than 10:00 a.m.
(San Francisco time) on the date of funding with respect to the funding of a
Base Rate Loan, together with most recent Borrowing Base Certificate, if
required, and Agent's request to the Lenders to fund the Borrowing requested (or
such lesser amount as Agent shall determine to be appropriate, in the exercise
of its discretion). Each Lender shall make the amount of such Lender's Pro Rata
Share of the requested Borrowing available to Agent in same day funds, to such
account of Agent as Agent may designate, not later than 1:00 p.m. (San Francisco
time) on the Funding Date applicable thereto. Revolving Loans made by the
Lenders pursuant to this Section 2.3(a) are sometimes referred to herein as
                         --------------
"Lender Advances" and the Lender Advances shall constitute Revolving Loans for
 ---------------
all purposes of this Agreement and the other Loan Documents. After Agent's
receipt of the proceeds of any such Lender Advances, unless Agent determines
that any applicable condition set forth in Article 10 has not been satisfied,
                                           ----------
Agent shall make the proceeds of such Lender Advances available to Borrower on
the applicable Funding Date by transferring same day funds equal to the proceeds
of such Lender Advances received by Agent to the account of Borrower designated
in writing by Borrower; provided, however, that the amount of Lender Advances
and other Revolving Loans so made on any date shall in no event exceed the
Excess Availability of Borrower, except as permitted in Section 2.3(b)(ii)
                                                        ------------------
below.

          (b)  Agent Advances.
               --------------

               (i)  Notwithstanding anything to the contrary contained herein,
for administrative convenience and in order to reduce the number of funds
transfers among Borrower and the Lenders, Agent may (but shall not be obligated
to), and Borrower and the Lenders hereby authorize Agent to, make Revolving
Loans on behalf of the Lenders, subject to the procedures for settlement set
forth in Section 2.4 below. Any such Revolving Loans made by Agent on behalf of
         -----------
Lenders pursuant to this Section 2.3(b)(i) and any Revolving Loans made by Agent
                         -----------------
on behalf of Lenders pursuant to Section 2.3(b)(ii) below are referred to herein
                                 ------------------
as "Agent Advances." Agent Advances shall constitute Revolving Loans for all
    --------------
purposes of this Agreement and the other Loan Documents. Agent may apply or
cause to be applied any payments or other amounts which it receives for the
repayment of the outstanding Revolving Loans pursuant to the terms hereof to the
Revolving Loans constituting Agent Advances prior to the payment of any of the
other Revolving Loans. Agent shall have no duty to make or to continue to make
any Agent Advances.

               (ii) Any contrary provision of this Agreement notwithstanding,
but subject to the limitations set forth in the provisos contained in this
Section 2.3(b)(ii), Agent is hereby authorized by Borrower and the Lenders to
- ------------------
make Revolving Loans to Borrower on behalf of the Lenders which Agent, in its
reasonable business judgment, deems necessary or desirable (A) to preserve or
protect the Collateral or any portion thereof; (B) to enhance the likelihood of,
or maximize the amount of, repayment of the Loans and other Obligations, or to
otherwise avoid a Default or an Event of Default hereunder, or to prevent or
minimize the occurrence of a Material Adverse Effect; (C) to pay any other
amount chargeable to Borrower pursuant to the terms of this Agreement,
including, without limitation,

                                      25

costs, fees and expenses as described in Section 15.5; or (D) if the conditions
                                         ------------
for Borrowing under Section 10.2(c) cannot be fulfilled, to advance a Revolving
                    ---------------
Loan to repay any principal or interest or other amounts, including
reimbursement obligations in connection with Letters of Credit, and fees and
premiums payable to the Lenders hereunder (any advances made pursuant to this
Section 2.3(b)(ii) are also referred to herein as "Agent Advances"); and
- ------------------                                 --------------
provided, that Agent shall have no obligation to Borrower to make an Agent
Advance under any circumstances. In no event shall Agent make an Agent Advance
if the aggregate Revolving Loan Usage (including such Agent Advance) would
exceed the Maximum Amount. Agent shall notify each Lender and Agent in writing
of each Agent Advance made pursuant to this Section 2.3(b)(ii).
                                            ------------------

               (iii) Any Agent Advance made pursuant to a Loan Request under
Section 2.3(b)(i) hereof shall be repayable at the end of the Interest Period
- -----------------
selected by the Borrower in such Loan Request. Agent Advances made pursuant to
Section 2.3(b)(ii) shall be repayable on demand and secured by the Collateral
- ------------------
and shall constitute Revolving Loans and Obligations hereunder. Any Agent
Advance made pursuant to a Loan Request under Section 2.3(b)(i) hereof shall
                                              -----------------
bear interest at the Rate(s) applicable to the Revolving Loan(s) requested by
the Borrower in such Loan Request. Any Agent Advance made pursuant to Section
                                                                      -------
2.3(b)(ii) hereof shall bear interest at the Default Rate without regard to the
- ----------
presence or absence of a Default or Event of Default. Agent shall request that
each Lender make available to Agent its Pro Rata Share of each Agent Advance
made pursuant to this Section 2.3(b), and each Lender agrees that it shall make
                      --------------
available to Agent, promptly upon Agent's demand, in immediately available
funds, an amount equal to such Lenders' Pro Rata Share of each Agent Advance
made by Agent pursuant to this Section 2.3(b).
                               --------------

          (c)  Defaulting Lenders. Unless Agent receives notice from a Lender at
               ------------------
least one (1) Business Day prior to the date of a Borrowing that such Lender
will not make available as and when required hereunder to Agent for the account
of Borrower the amount of that Lender's Pro Rata Share of the Borrowing, Agent
may assume that each Lender has made such amount available to Agent in
immediately available funds on the Funding Date and Agent may (but shall not be
so required), in reliance upon such assumption, make available to Borrower on
such date a Revolving Loan in the corresponding amount. If and to the extent any
Lender shall not have made its full amount available to Agent in immediately
available funds and Agent in such circumstances has made available to Borrower
such amount, then Lender shall on the Business Day following such Funding Date
make such amount available to Agent, together with interest, to be retained by
Agent for its own account, at the Base Rate for each day after the Funding Date
until (but not including) the date paid. A notice of Agent submitted to any
Lender with respect to amounts owing under this subsection shall be prima facia
evidence of the truth thereof, absent manifest error. If such amount is so made
available, such payment to Agent shall constitute such Lender's Loan on the date
of Borrowing for all purposes of this Agreement. If such amount is not made
available to Agent on the Business Day following the Funding Date, Agent will
notify Borrower of such failure to fund and, upon demand by Agent, Borrower
shall pay such amount to Agent for Agent's account, together with interest
thereon for each day elapsed since the date of such Borrowing, at a rate per
annum equal to the Rate applicable at the time to the Loan comprising such
Borrowing. The failure of any Lender to make any Loan on any Funding Date shall
not relieve any other Lender of any obligation hereunder to make a Loan on such
Funding Date, but no Lender shall be responsible for the failure of any other
Lender to make the Loan to be made by such other Lender on any Funding Date. Any
Lender that fails to make any Loan on any Funding Date and continues to fail to
make such Loan within one (1) Business Day after written demand upon it by Agent
to do so, shall constitute a "Defaulting Lender" for purposes of this Agreement.
                              -----------------

                                      26
<PAGE>

Loan and Security Agreement

               (i)  In addition, any Lender that fails to make any payment to
Agent pursuant to Section 2.4 hereof or as required by any other Section hereof
                  -----------
in connection with any Agent Advance made pursuant to Section 2.4(b) hereof and
                                                      --------------
continues to fail to make such payment within one (1) Business Day after written
demand upon it by Agent to do so, shall constitute a "Defaulting Lender" for
                                                      -----------------
purposes of this Agreement.

               (ii) For purposes of voting or consenting to matters with respect
to the Loan Documents and determining Pro Rata Shares, any Defaulting Lender
shall be deemed not to be a "Lender" and such Lender's Commitment shall be
deemed to be zero (-0-). This Section shall remain effective with respect to
such Lender until the Majority Lenders and Agent shall have waived such Lender's
default in writing. The operation of this Section shall not be construed to
increase or otherwise affect the Commitment of any Lender, or relieve or excuse
the performance by Borrower of its duties and obligations hereunder.

     2.4  Settlement. It is agreed that each Lender's funded portion of the
          ----------
Revolving Loans is intended by the Lenders to be equal at all times to such
Lender's Pro Rata Share of the outstanding Revolving Loans. Notwithstanding such
agreement, Agent and the Lenders agree (which agreement shall not be for the
benefit of or enforceable by Borrower) that in order to facilitate the
administration of this Agreement and the other Loan Documents, settlement among
them as to the Revolving Loans (including Lender Advances and Agent Advances)
shall take place on a periodic basis in accordance with the following
provisions.

          (a)  Computation of Pro Rata Shares. The amount of the Pro Rata Share
               ------------------------------
of each Lender of the Revolving Loans shall be computed monthly (or on a more
frequent basis if so determined by Agent) and the amounts actually funded by
each Lender shall be adjusted monthly (or on a more frequent basis if determined
by Agent) upward or downward based on all Revolving Loans (including Lender
Advances and Agent Advances) and repayments of Revolving Loans received by Agent
as of the close of business in San Francisco on the last Business Day of the
monthly (or shorter) period specified by Agent (such date being referred to
herein as the "Settlement Date"). Agent shall deliver to each of the Lenders
               ---------------
periodically a summary statement of the amount of outstanding Revolving Loans
(including Lender Advances and Agent Advances) and Letters of Credit, and shall
use its best efforts to deliver such a summary statement no later than two (2)
Business Days after the relevant Settlement Date (although the failure to so
deliver such a summary statement at such time shall not affect the obligation of
the Lenders under this Section 2.4).
                       -----------

          (b)  Transfers. Upon receipt of the summary statement, each Lender
               ---------
shall transfer to Agent, as provided below, or Agent shall transfer to each
Lender, as provided below, such amounts as are necessary to ensure that after
giving effect to all such transfers, the amount of Revolving Loans made by each
Lender shall be equal to such Lender's Pro Rata Share of the aggregate amount of
the Revolving Loans outstanding as of such Settlement Date. If the then
outstanding balance funded by a Lender in respect of the Revolving Loans exceeds
such Lender's Pro Rata Share of the aggregate amount of the Revolving Loans
outstanding as of the Settlement Date, then Agent shall promptly transfer to
such Lender in immediately available funds to such account of such Lender as it
may designate, the amount required so that such Lender shall, upon receipt of
such amount, have funded its Pro Rata Share of the Revolving Loans as of the
Settlement Date. If the then outstanding balance funded by a Lender in respect
of the Revolving Loans is less than such Lender's Pro Rata Share of the
aggregate amount of the Revolving Loans outstanding as of the Settlement Date,
such Lender shall by no later than 1:00 p.m. (San Francisco time) on the
Business Day subsequent to the receipt of the summary statement, transfer in
immediately available funds to such account of Agent as Agent may designate, the
amount required so

                                      27
<PAGE>

Loan and Security Agreement

that such Lender shall, upon transfer of such amount, have funded its Pro Rata
Share of the Revolving Loans as of the Settlement Date. The obligations of each
Lender to transfer such funds is irrevocable, unconditional and without recourse
to, or warranty by, Agent. If any such amount is not transferred to Agent by any
Lender when required, Agent shall be entitled to recover for its account such
amount promptly on demand upon such Lender, together with interest thereon at
Base Rate for each day after the date such sums are due until (but not
including) the date paid.

     2.5  Notation. Agent shall record on its books the principal amount of the
          --------
Revolving Loans owing to each Lender, including Lender Advances and Agent
Advances, the Rates applicable to such Revolving Loans, Lender Advances and
Agent Advances, and the interests therein of each Lender, from time to time,
which information shall be made available to any Lender upon request therefor.
In addition, each Lender is authorized, at such Lender's option, to note the
date and amount of each payment or prepayment of principal of such Lender's
Revolving Loans in its books and records, including computer records, such books
and records constituting rebuttably presumptive evidence, absent manifest error,
of the accuracy of the information contained therein.

     2.6  Lenders' Failure to Perform. All Revolving Loans (other than Agent
          ---------------------------
Advances) shall be made by the Lenders simultaneously and in accordance with
their Pro Rata Shares. It is understood that (a) no Lender shall be responsible
for any failure by any other Lender to perform its obligation to make any
Revolving Loans hereunder, nor shall any Commitment of any Lender be increased
or decreased as a result of any failure by any other Lender to perform its
obligation to make any Revolving Loans hereunder, and (b) no failure by any
Lender to perform its obligation to make any Revolving Loans hereunder shall
excuse any other Lender from its obligation to make any Revolving Loans
hereunder.

     2.7  Letters of Credit.
          -----------------

          (a)  Agreement to Cause Issuance. Subject to the terms and conditions
               ---------------------------
of this Agreement, and in reliance upon the representations and warranties of
Borrower herein set forth, Agent agrees to take reasonable steps to cause to be
issued for the account of Borrower one or more stand-by or documentary Letters
of Credit (each such letter of credit, a "Letter of Credit" and such Letters of
                                          ----------------
Credit, collectively, the "Letters of Credit") in accordance with this Section
                           -----------------                           -------
2.7 from time to time during the term of this Agreement, which Letters of Credit
- ---
will be opened for trade purposes or to secure workers compensation obligations.
Any Letter of Credit may be issued by Union Bank of California, N.A. or any
Affiliate or Agent-Related Person, provided, however, that neither Union Bank of
California, N.A. nor any of its Affiliates or Agent-Related Persons shall have
any obligation to issue a Letter of Credit for the account of Borrower. Upon the
issuance of any Letter of Credit, Agent shall establish a reserve to reduce the
Availability in an amount equal to the face amount of such Letter of Credit,
plus such additional amounts with respect thereto as Agent determines are
appropriate. Promptly after the issuance of any Letter of Credit, Agent shall
give notice to each Lender of the issuance of such Letter of Credit.

          (b)  Terms of Letters of Credit. Any Letter of Credit shall contain
               --------------------------
terms and conditions acceptable to Agent and the issuer thereof. Without
limiting the generality of the foregoing, in no event: (i) may the term of any
documentary Letter of Credit exceed one hundred eighty (180) days, (ii) may any
Letter of Credit, whether documentary or standby, have a term in excess of one
(1) year, or (iii) may any Letter of Credit, whether documentary or standby,
expire on a date that is later than five (5) Business Days prior to the Stated
Termination Date. Any Letter of Credit containing an automatic renewal provision
shall also contain a provision pursuant to which, notwithstanding any other
provision thereof, it shall expire no later than the date that is five (5)
Business Days prior to the Stated Termination

                                      28

Loan and Security Agreement

Date and a provision pursuant to which the issuer thereof may, by notice to the
beneficiary of such Letter of Credit at least thirty (30) days prior to the
expiration of its term, elect not to renew such Letter of Credit for an
additional term.

          Agent shall not be obligated to cause any Letter of Credit to be
extended or amended unless the requirements of this Section 2.7 are met as
                                                    -----------
though a new Letter of Credit were being requested and issued.  With respect to
any Letter of Credit which contains any "evergreen" or automatic renewal
provision, each Lender shall be deemed to have consented to any such extension
or renewal unless any such Lender shall have provided to Agent, not less than
thirty (30) days prior to the last date on which the applicable issuer can in
accordance with the terms of the applicable Letter of Credit decline to extend
or renew such Letter of Credit, written notice that it declines to consent to
any such extension or renewal, provided that if all of the requirements of this
Section 2.7 are met, no Lender shall, or shall have any right to, decline to
- -----------
consent to any such extension or renewal.

          (c)  Other Conditions. In addition to being subject to the
               ----------------
satisfaction of the applicable conditions precedent contained in Article 10, the
                                                                 ----------

Credit is subject to the following conditions precedent having been satisfied in
a manner satisfactory to Agent:

such Letter of Credit, at such times and in such manner as such proposed issuer
may prescribe, an application in form and substance satisfactory to such
proposed issuer for the issuance of the Letter of Credit and such other
documents as may be required pursuant to the terms thereof, and the form and
terms of the proposed Letter of Credit shall be satisfactory to Agent and such
proposed issuer;

arbitrator or Governmental Authority shall purport by its terms to enjoin or
restrain money center banks generally from issuing Letters of Credit of the type
and in the amount of the proposed Letter of Credit, and no law, rule or
regulation applicable to money center banks generally and no request or
directive (whether or not having the force of law) from any Governmental
Authority with jurisdiction over money center banks generally shall prohibit, or
request that the proposed issuer of such Letter of Credit refrain from, the
issuance of Letters of Credit generally or the issuance of such Letters of
Credit;

               (iii) Agent shall not have received a currently effective written
notice from any Lender that one or more of the conditions set forth in Article
                                                                       -------

          -----
or in connection with the Letters of Credit outstanding as of the date of the
proposed Letter of Credit, as determined by Agent;

               (v)   the face amount of the proposed Letter of Credit shall not
exceed an amount equal to the Excess Availability as of the date of the proposed
Letter of Credit; and

drawing under any Letter of Credit by the beneficiary thereof, Borrower shall be
deemed to have concurrently given a Loan Request and Agent shall, at its option,
either notify the Lenders to make Lender Advances pursuant to Section 2.3(a) or

               (i)   Immediately upon the issuance of any Letter of Credit in
accordance with this Section, each Lender shall be deemed to have irrevocably
and unconditionally purchased and received, without recourse or warranty, an
undivided interest and participation in such letter of credit and in the credit
support or enhancement provided through Agent to such issuer in connection with
the issuance of such Letter of Credit, in an amount equal to such Lender's Pro
Rata Share of the face amount of such Letter of Credit (including, without
limitation, all obligations of Borrower with respect thereto, and any security
therefor or guaranty pertaining thereto).

               (ii)  Whenever Agent receives a payment from Borrower on account
of reimbursement obligations in respect of a Letter of Credit as to which Agent
has previously received for the account of the issuer thereof payment from a
Lender pursuant to this Section, Agent shall promptly pay to such Lender such
Lender's Pro Rata Share of such payment from Borrower in dollars. Each such
payment shall be made by Agent on the Business Day on which Agent receives from
Borrower immediately available funds paid to such Person pursuant to the
immediately preceding sentence, if received prior to 1:00 p.m. (San Francisco
time) on such Business Day and otherwise on the next succeeding Business Day.

               (iii) Upon the request of any Lender, Agent shall furnish to such

of Credit, and such other documentation as may reasonably be requested by such
Lender.

credit support or enhancement provided through Agent with respect to a Letter of
Credit, and the obligations of Borrower to make payments to Agent, for the
account of the Lenders, shall be irrevocable, not subject to any qualification
or exception whatsoever, including, without limitation, any of the following
circumstances:

               (i)   any lack of validity or enforceability of this Agreement,
any of the other Loan Documents, the Letter of Credit or any document executed
in connection therewith;

               (ii)  the existence of any claim, setoff, defense or other right
which Borrower may have at any time against a beneficiary named in a Letter of
Credit or any transferee of any Letter of Credit (or any Person for whom any
such transferee may be acting), any Lender, Agent, the issuer of such Letter of
Credit or any other Person, whether in connection with this Agreement, any
Letter of Credit, the transactions contemplated herein or any unrelated
transactions (including any underlying transactions between Borrower or any
other Person and the beneficiary named in any Letter of Credit);

insufficient in any respect or any statement therein being untrue or inaccurate
in any respect;

               (iv)  the surrender or impairment of any security for the

               (v)   the occurrence of any Default or Event of Default.

on behalf of Borrower received by Agent with respect to any Letter of Credit (or
any guaranty by Borrower or reimbursement obligation of Borrower relating
thereto) and distributed by Agent to the Lenders on account of their respective
participations therein is thereafter set aside, avoided or recovered from Agent
in connection with any receivership, liquidation or bankruptcy proceeding, the
Lenders shall, upon demand by Agent, promptly pay to Agent their respective Pro
Rata Shares of such amount set aside, avoided or recovered, together with
interest at the rate required to be paid by Agent upon the amount required to be
repaid by it.

          (i)  Compensation for Letters of Credit.

standard fees for issuing, administering, amending, renewing, paying and
canceling Letters of Credit and all other fees associated with issuing or
servicing Letters of Credit, as and when assessed.

          (j)  Indemnification; Exoneration.
               ----------------------------

               (i)   In addition to amounts payable as elsewhere provided in

consequence, direct or indirect, of the issuance of any Letter of Credit or the
provision of any credit support or enhancement in connection therewith.

               (ii)  As among Borrower, the Lenders and Agent, Borrower assumes
all risks of the acts and omissions of, or misuse of any of the Letters of
Credit by, the respective beneficiaries of such Letters of Credit. In
furtherance and not in limitation of the foregoing, the Lenders and Agent shall
not be responsible for: (A) the form, validity, sufficiency, accuracy,

such Letter of Credit; or (H) any consequences arising from causes beyond the
control of the Lenders or Agent, including, without limitation, any act or
omission, whether rightful or wrongful, of any present or future de jure or de
facto Governmental Authority. None of the foregoing shall affect, impair or
prevent the vesting of any rights or powers of Agent and the Lenders under this
Section.

               (iii) In furtherance and extension, and not in limitation, of the
specific provisions set forth above, any action taken or omitted by Agent or any
Lender under or in connection with any of the Letters of Credit or any related
certificates, if taken or omitted in the absence of gross negligence or willful
misconduct, shall not put Agent or any Lender under any resulting liability to
Borrower or relieve Borrower of any of its obligations hereunder to any such
Person.

               (iv)  The undertaking in this Section shall survive the
termination of this Agreement and the repayment of all Obligations hereunder.

termination of this Agreement, then upon such termination Borrower shall deposit
with Agent, for the ratable benefit of the Lenders in proportion to their Pro
Rata Shares, with respect to each Letter of Credit then outstanding, as the
Majority Lenders, in their discretion shall specify, either (i) a standby letter
of credit (a "Supporting Letter of Credit") in form and substance satisfactory
              ---------------------------
to Agent, issued by an issuer satisfactory to Agent in an amount equal to the
greatest amount for which such Letter of Credit may be drawn, under which

reimburse Agent and the Lenders for payments made by Agent and the Lenders under
such Letter of Credit or under any credit support or enhancement provided
through Agent with respect thereto, or (ii) cash in amounts necessary to

               (ii)  Interest on the principal balance of any Base Rate Loan
requested by Borrower pursuant to a Loan Request will be payable at the Base
Rate;

               (iii) Interest on the principal balance of any Loan at any time
for which Borrower has failed to submit an effective Loan Request will be
payable at the Base Rate;

               (iv)  Except as otherwise provided in this Section 3.1(a) or in
                                                          --------------
Section 3.1(b) hereof, interest on the principal balance of any other
- --------------
outstanding Obligations will be payable at the Base Rate;

provided, however, that in no event shall the interest rate on any Obligations
exceed the Maximum Rate described in Section 3.2.  All interest charges shall be
                                     -----------
computed on the basis of a year of three hundred sixty (360) days and actual
days elapsed, and, with respect to Revolving Loans, shall be payable by Borrower
to Agent (for the ratable benefit of the Lenders in proportion to their Pro Rata
Shares), on the last day of each calendar month, and on the last day of the
                                                 ---
Interest Period selected by Borrower in its Loan Request therefor, and on the
                                                                   ---

Loan, and on the Termination Date.  Interest charges with respect to any other
      ---
Obligations shall be payable by Borrower on demand by Agent.

          (b)  Default Rate. Notwithstanding anything to the contrary contained
               ------------
in this Agreement or any other Loan Document, any Obligations payable by
Borrower and not paid on the due date thereof, and any Obligations outstanding
after an Event of Default, shall bear interest at the Default Rate.

     3.2  Maximum Interest Rate. Notwithstanding anything to the contrary
          ---------------------
contained in Section 3.1 hereof, in no event shall any interest rate provided
             -----------
for hereunder exceed the maximum rate permissible for corporate borrowers under
applicable law for loans of the type provided for hereunder (the "Maximum
                                                                  --------
Rate"). If, during any period of time, any Rate applicable to any Obligations,
- ----
absent such limitation, would have exceeded the Maximum Rate, then the Rate for
such Obligations for such period shall be the Maximum Rate and, if thereafter
that Rate applicable to such Obligations would otherwise be less than the
Maximum Rate, then that Rate shall remain at the Maximum Rate until such time as
the amount of interest paid hereunder equals the amount of interest which would
have been paid if the same had not been limited by the Maximum Rate. In the
event that, upon payment in full of the Obligations under this Agreement, the
total amount of interest paid or accrued under the terms of this Agreement is
less than the total amount of interest which would, but for this Section 3.2,
                                                                 -----------
have been paid or accrued if the interest rates otherwise set forth in this
Agreement had at all times been in effect, then Borrower shall, to the extent
permitted by applicable law, pay Agent, for the account of the Lenders, an
amount equal to the difference between (a) the lesser of (i) the amount of
interest which would have been charged if the Maximum Rate had, at all times,
been in effect; or (ii) the amount of interest which would have accrued had the
interest rates otherwise set forth in this Agreement, at all times, been in
effect; and (b) the amount of interest actually paid or accrued under this
Agreement. In the event that a court determines that Agent and/or any Lender has
received interest and other charges hereunder in excess of the Maximum Rate,
such excess shall be deemed received on account of, and shall automatically be
applied to reduce, the Obligations other than interest, in the inverse order of
maturity, and if there are no Obligations outstanding, Agent and/or such Lender,
as applicable, shall refund to Borrower such excess.

     3.3  Unused Line Fee. On the last Business Day of each Fiscal Quarter and
          ---------------
on the Termination Date, Borrower agrees to pay to Agent, for the ratable
benefit of the Lenders in proportion to their Pro Rata Shares, an unused line
fee equal to three hundred seventy-five one thousandths of a

percent (0.375%) per annum on the average daily amount by which the Maximum
Amount exceeded the sum of the average daily outstanding amount of Revolving
Loans and the undrawn amount of all outstanding Letters of Credit during the
immediately preceding three (3)-month period (or shorter period if calculated on
the Termination Date). In the event that the average daily outstanding amount of
Revolving Loans and the undrawn amount of all outstanding Letters of Credit is
less than thirty three percent (33%) of the Maximum Amount for any twelve (12)
month-period, as measured on each anniversary of the Closing Date, then, on the
applicable anniversary of the Closing Date, Borrower agrees to pay to Agent, for
the ratable benefit of the Lenders in proportion to their Pro Rata Shares, an
additional unused line fee equal to one hundred twenty-five one thousandths of a
percent (0.125%) per annum on the average daily amount by which the Maximum
Amount exceeded the sum of the average daily outstanding amount of Revolving
Loans and the undrawn amount of all outstanding Letters of Credit during the
immediately preceding twelve (12)-month period. The unused line fee and the
additional unused line fee shall be computed on the basis of a three hundred
sixty (360)-day year for the actual number of days elapsed. All payments
received by Agent on account of Accounts or as proceeds of other Collateral
shall be deemed to be credited to the outstanding Loans hereunder immediately
upon the application of such amounts by Agent to repay any Revolving Loans
hereunder pursuant to Section 4.4 hereof for purposes of calculating the unused
                      -----------
line fee and the additional unused line fee pursuant to this Section 3.3.

annum of the average daily stated amounts of each such Letters of Credit issued
for Borrower's account during the immediately preceding month, during such
periods that Borrower is in compliance with all of the covenants set forth in
Section 9.20 hereof; plus (b) all out-of-pocket costs, fees and expenses
- ------------         ----
incurred by Agent in connection with the application for, issuance of or
amendment to each such Letter of Credit in the immediately preceding month,
which costs, fees and expenses shall include all "fronting fees" required to be
paid by Agent to such issuer for the assumption of the settlement risk in
connection with the issuance of such Letter of Credit. The Letter of Credit Fee
shall be payable monthly, in arrears, commencing with the first Business Day of
the month following the issuance of any Letter of Credit and continuing on the
first day of each month during which any Letter of Credit remains outstanding.
The Letter of Credit Fee shall be computed on the basis of a three hundred sixty
(360)-day year for the actual number of days elapsed.

     3.5   Audit Fees. Borrower agrees to pay to Agent, solely for its own
           ----------
account, and to the Lenders, for their respective own accounts, all costs, fees
and expenses (including travel expenses) reasonably incurred by their internal
auditors or in connection with auditors engaged by Agent in connection with
audits of Borrower performed by such auditors during the term of this Agreement;
provided, however, that unless a Default or an Event of Default shall have
occurred, Borrower shall have an obligation to pay such costs, fees, and
expenses in connection with one (1) audit during each Fiscal Year of Borrower.

     3.6   Fee Letter. Borrower agrees to pay to Agent all of the fees set forth
           ----------

principal balance of each Revolving Loan on the earlier of (i) the last day of
the Interest Period for such Revolving Loan selected by Borrower in the Loan
Request therefor, or (ii) the Termination Date; provided, however, that with
respect to repayment of principal on the last day of an Interest Period,
Borrower may simultaneously repay and reborrow any such Revolving Loan on such
date, subject to the terms of this Agreement.

          (b)  Mandatory Prepayments. In addition to the repayments required in

- --------------
demand of Agent, Borrower shall make a mandatory prepayment to Agent, for the
account of the Lenders, of the following amounts: (i) the amount, without
duplication, by which the Revolving Loan Usage exceeds the Availability; (ii)
the aggregate net proceeds of any offering of any equity securities of Borrower
after the Closing Date (with the exception of any initial public offering of
Borrower's equity securities made on or before June 30, 2000, provided that
Borrower's existing shareholders do not sell their shares in connection with
such initial public offering); and (iii) any amounts received by Borrower which
are described in clauses (b), (c) or (d) of the definition of "Availability." In
the event of any such mandatory prepayment, Borrower shall pay the Breakage
Costs specified in Section 5.4 hereof.
                   -----------

          (c)  Prepayment of Revolving Loans. Borrower may, upon at least (1)
               -----------------------------

prepayment on the amount prepaid, (ii) if Borrower makes a prepayment of any

thirty (30) Business Days' prior written notice to Agent and the Lenders,
without the payment of any special prepayment fee or premium (with the exception
of any Breakage Costs payable as a result of the prepayment of any LIBOR Loan
prior to the last day of the applicable Interest Period therefor), upon (i) the
indefeasible payment in full of all outstanding Revolving Loans, together with
accrued interest thereon, and the cancellation of all outstanding Letters of
Credit, and (ii) the payment in full in cash of all other Obligations together
with accrued interest thereon.

          (b)  Reduction. Borrower may permanently reduce the unused portion of

that Borrower shall, contemporaneously with each such reduction, repay or prepay
the Revolving Loans and Letters of Credit to the extent that the aggregate
principal amount thereof then outstanding exceeds the Maximum Amount as so
reduced, together with any Breakage Costs amounts payable by Borrower hereunder
upon prepayment. From the effective date of any such reduction, the term
"Maximum Amount" shall mean the Maximum Amount of the Commitments, as so
reduced. Once reduced, the Maximum Amount of the Commitments may not be
subsequently increased.

          (a)  No Setoffs, etc. All payments to be made by Borrower shall be
               ---------------
made without set-off, recoupment or counterclaim. Borrower hereby irrevocably
authorizes Agent to automatically deduct from Borrower's account at any branch
of Union Bank of California, N.A., all amounts payable by Borrower to Agent or
any Lender, on the due date thereof. If, for any reason, Agent can not or does
not so deduct any such amount payable by Borrower, Borrower shall make such
payment to Agent, for itself or for the account of the Lenders, as applicable,
at Agent's payment address as follows:

Union Bank of California N.A.
Monterey Park, California
Account Number:  070-196431
Account Name:  Wire Transfer Clearing
Attn:  Commercial Loan Operations
Reference:  Pac-West Telecomm, Inc.
ABA Number:  122-000-496

which payment shall be made in dollars and in immediately available funds no
later than 11:00 a.m. (San Francisco time) on the due date specified herein.
Any payment received by Agent later than 11:00 a.m. (San Francisco time), for
any reason, shall, at the option of Agent, be deemed to have been received on
the following Business Day and any applicable interest or fee shall accrue.

          (b)  Business Day Payments. Whenever any payment is due on a day other
               ---------------------
than a Business Day, such payment shall be made on the following Business Day,
and such extension of time shall in such case be included in the computation of
interest or fees, as the case may be.

          (c)  Distributions by Agent. Unless Agent receives notice from
               ----------------------
Borrower prior to the date on which any payment is due to the Lenders that
Borrower will not make such payment in full as and when required, Agent may
assume that Borrower has made such payment in full to Agent on such date in
immediately available funds and Agent may (but shall not be so required, unless
Agent actually receives such payment by 11:00 a.m. (San Francisco time), on such
date), in reliance upon such assumption, distribute to each Lender on such due
date an amount equal to the amount then due such Lender. If and to the extent
Borrower has not made such payment in full to Agent, each Lender shall repay to
Agent, promptly on demand, such amount distributed to such Lender (provided,
however, that if such Lender shall not make such funds available within one (1)
Business Day of Agent's demand, interest shall accrue on such funds and shall be
payable by such Lender at the Base Rate for each day from and after the date
such amount is distributed to such Lender until (but not including) the date
repaid).

     4.4  Apportionment, Application and Reversal of Payments. All payments made
          ---------------------------------------------------
by Borrower and all proceeds of Accounts or other Collateral received by Agent
or any Lender shall be applied, subject to the provisions of this Agreement

Loan and Security Agreement

proceeds is invalidated, declared fraudulent, set aside, determined to be void
or voidable as a preference, impermissible setoff, or a diversion of trust
funds, or for any other reason, then the Obligations or part thereof intended to
be satisfied shall be revived and continue and this Agreement shall continue in
full force as if such payment or proceeds had not been received by Agent or such
Lender, and Borrower shall be liable to pay to Agent, and hereby does indemnify
Agent and the Lenders and hold Agent and the Lenders harmless for, the amount of
such payment or proceeds surrendered, plus interest thereon at the Default Rate
from the date so surrendered and any other costs, expenses and penalties paid by
Agent and Lenders in connection therewith. The provisions of this Section shall
be and remain effective notwithstanding any contrary action which may have been
taken by Agent or any Lender in reliance upon such payment or application of
proceeds, and any such contrary action so taken shall be without prejudice to
Agent's and the Lenders' rights under this Agreement and shall be deemed to have

shall be admissible in any action or proceeding arising therefrom, and shall
constitute prima facia proof thereof, absent manifest error. Agent will provide
to Borrower and each Lender a monthly statement of Loans, payments and other
transactions pursuant to this Agreement. Such statement shall be deemed correct,
accurate, and binding on Borrower and an account stated (except for reversals
and reapplications of payments made as provided in Section 4.5 and corrections
                                                   -----------
of errors discovered by Agent), unless Borrower notifies Agent in writing to the
contrary within ninety (90) days after such statement is rendered. In the event
a timely written notice of objections is given by Borrower, only the items to
which exception is expressly made will be considered to be disputed by Borrower.

                                  ARTICLE V.
                    TAXES, YIELD PROTECTION AND ILLEGALITY

     5.1  Taxes.
          -----

          (a)  Payments Free From Taxes. Any and all payments by Borrower to
               ------------------------
each Lender and Agent under this Agreement and any other Loan Document shall be
made free and clear of, and without deduction or withholding for, any Taxes. In
addition, Borrower shall pay all Other Taxes.

          (b)  Indemnification. Borrower agrees to indemnify and hold harmless
               ---------------
Agent and each Lender for the full amount of Taxes or Other Taxes (including any
Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this
Section) paid by any of the Lenders or Agent and any liability (including
penalties, interest, additions to tax and expenses) arising therefrom or with
respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted. Payment under this indemnification shall be made within thirty
(30) days after the date any Lender or Agent makes written demand therefor. The
undertaking in this Section shall survive the termination of this Agreement and
the payment of all Obligations hereunder.

          (c)  Withholdings. If Borrower shall be required by law to deduct or
               ------------
withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder or under any other Loan Document to any Lender or Agent, then:

                                      39
<PAGE>

Loan and Security Agreement

               (i)    the sum payable shall be increased as necessary so that
after making all required deductions and withholdings (including deductions and
withholdings applicable to additional sums payable under this Section) such
Lender or Agent, as the case may be, receives an amount equal to the sum it
would have received had no such deductions or withholdings been made;

               (ii)   Borrower shall make such deductions and withholdings;

               (iii)  Borrower shall pay the full amount deducted or withheld to
the relevant taxing authority or other authority in accordance with applicable
law; and

               (iv)   Borrower shall also pay to each Lender and Agent, for the
account of such Lender or Agent, as applicable, at the time interest is paid,
all additional amounts which the respective Lender or Agent specifies as
necessary to preserve the after-tax yield such Lender or Agent would have
received if such Taxes or Other Taxes had not been imposed.

          (d)  Receipt. Within thirty (30) days after the date of any payment by
               -------
Borrower of Taxes or Other Taxes, Borrower shall furnish to Agent the original
or a certified copy of a receipt evidencing payment thereof, or other evidence
of payment satisfactory to Agent.

          (e)  Elimination of Additional Payments. If Borrower is required to
               ----------------------------------
pay additional amounts to any Lender or Agent pursuant to subsection (c) of this
Section, then such Lender shall use reasonable efforts (consistent with legal
and regulatory restrictions) to change the jurisdiction of its lending office so
as to eliminate any such additional payment by Borrower which may thereafter
accrue, if such change in the judgment of such Lender is not otherwise
disadvantageous to such Lender.

     5.2  Increased Costs, Reduction of Return and Illegality; Capital Adequacy.
          ---------------------------------------------------------------------


          (a)  Regulation D Compensation. If any Lender shall have determined
               -------------------------
that (a) the introduction of any Capital Adequacy Regulation, (b) any change in
any Capital Adequacy Regulation, (c) any change in the interpretation or
administration of any Capital Adequacy Regulation by any central bank or other
Governmental Authority charged with the interpretation or administration
thereof, or (d) compliance by the Lender or any corporation controlling the
Lender with any Capital Adequacy Regulation, affects or would affect the amount
of capital required or expected to be maintained by such Lender (or its funding
office) or any corporation controlling the Lender and (taking into consideration
such Lender's or such funding office's or corporation's policies with respect to
capital adequacy and such Lender's desired return on capital) determines that
the amount of such capital is increased as a consequence of its Commitment,
loans, credits or obligations under this Agreement, then, upon demand of such
Lender to Borrower, Borrower shall pay to such Lender, from time to time as
specified by such Lender, additional amounts sufficient to compensate such
Lender for such increase.

          (b)  Regulation D Compensation. For so long as any Lender is required
               -------------------------
to maintain reserves against Eurocurrency Liabilities (or any other category of
liabilities which include deposits by reference to which any Rate is determined
or any category of extensions of credit or other assets which includes loans by
a non-United States office of any Lender to United States residents) and, as a
result, the cost to such Lender (or its funding office) of making or maintaining
any Revolving Loans (including LIBOR Loans) is increased, then such Lender may
require Borrower to pay, upon written demand, an additional amount ("Additional
                                                                     ----------
Amount") at a rate per annum determined by such Lender in its reasonable
- ------
judgment to be the excess of (i) the Rate applicable to such Loan divided by one
minus the Reserve Requirements, over (ii) the Rate applicable to such Loan.

Loan and Security Agreement

          (c)  Illegality. If, after the date of this Agreement, any Lender
               ----------
determines (which determination shall be prima facia evidence of the truth
thereof for all purposes, in the absence of manifest error) that the adoption,
enactment or change after the date of this Agreement of any applicable law or
any rule, requirement, guideline, order or regulation of any Governmental
Authority, or any change in the interpretation or administration thereof by any
judicial or Governmental Authority, central bank, comparable agency or other
Person charged with the interpretation or administration thereof, or compliance
by such Lender (or any funding office or Affiliate of such Lender with any
request or directive (whether or not having the force of law) of any such
authority (a "Change of Law") shall make it unlawful, impossible or
              -------------
impracticable for such Lender (or its funding office or Affiliate) to make or
maintain a Loan at the LIBOR Rate, such Lender shall immediately notify Agent
and Borrower of such Change of Law. Thereafter, Borrower's right to request the
making of, and such Lender's obligation to make, a Loan at the LIBOR Rate shall
be terminated, and any outstanding Loan Request requesting any LIBOR Loan shall
automatically be deemed to be rescinded. The portion funded by such Lender of
any Loan so affected shall be prepaid immediately if such Lender shall notify
Borrower (which notice shall be prima facia evidence of the truth thereof for
all purposes, in the absence of manifest error) that such Lender may not
lawfully continue to fund or maintain such Loan. Borrower shall additionally pay
to such Lender, on the effective date of each such prepayment, any fee
(including any Breakage Costs) required pursuant to the provisions of this
Agreement.

     5.3  Funding Losses. Borrower shall reimburse each Lender and hold each
          --------------
Lender harmless from any loss or expense which the Lender may sustain or incur
as a consequence of the failure of Borrower to borrow a Loan after Borrower has
given (or is deemed to have given) a Loan Request, including any such loss or
expense arising from the liquidation or reemployment of funds obtained by it to
maintain its Loans or from fees payable to terminate the deposits from which
such funds were obtained.

     5.4  Breakage Costs. In the event that Borrower prepays any LIBOR Loan
          --------------
prior to the last day of the Interest Period therefor, whether voluntarily or
involuntarily, Borrower shall, upon demand by any Lender, reimburse such Lender
for all costs, losses and expenses in respect of any interest paid or premium or
penalty incurred by such Lender (or its lending branch or Affiliate) to lenders
or otherwise in respect of funds borrowed by or deposited with it to make or
maintain the LIBOR Loan which such Lender (or its lending branch or Affiliate)
may sustain as a result of such prepayment ("Breakage Costs"). Borrower
                                             --------------
understands that such Breakage Costs may include losses incurred by such Lender
as a result of funding and other contracts entered into by such Lender in order
to fund any LIBOR Loan hereunder.

     5.5  Certificates of Lenders. Any Lender claiming reimbursement or
          -----------------------
compensation under this Article 5 shall deliver to Borrower (with a copy to
Agent) a certificate setting forth in reasonable detail the amount payable to
the Lender hereunder and such certificate shall be prima facia evidence of the
truth thereof, in the absence of manifest error.

     5.6  Survival. The agreements and obligations of Borrower in this Article 5
          --------
shall survive the payment of all other Obligations.

     6.9  Collection of Accounts; Payments.
          --------------------------------

          (a)  Deposit Service. Schedule 6.9(a) is a true, correct and complete

remit all receipts in such Deposit Account to Borrower's Deposit Account at
Union Bank of California, N.A, at such time that monies received or accumulated

notwithstanding such instructions, Borrower receives any proceeds of Accounts,
it shall receive such payments as Agent's trustee, and shall immediately notify
each Agent as to its receipt of such proceeds and shall deposit such payments
into its Deposit Account at Union Bank of California, N.A.. All collections

Advance made pursuant to Section 2.3(b)(ii) is outstanding, Borrower may use all
                         ------------------
moneys deposited in a Deposit Account to be used for Borrower's working capital
needs and general corporate purposes; provided further, however, that
immediately (A) upon the occurrence and during the continuance of any Event of
Default, or (B) upon the making of any Agent Advance pursuant to Section
                                                                 -------
2.3(b)(ii) hereof, until such Agent Advance is repaid by Borrower in full, Agent
- ----------
may and, upon the instruction of the Majority Lenders, shall, reassume sole
control of such Deposit Account(s) and shall transfer all collections deposited
in such Deposit Account(s) to Agent for application to the Obligations pursuant
to Section 4.4 hereof. Agent may (and upon the instruction of the Majority
   -----------
Lenders, shall), at any time (y) following the occurrence and during the

Advance pursuant to Section 2.3(b)(ii) hereof until such Agent Advance is repaid
                    ------------------
in full, notify the Account Debtors that the Accounts have been assigned to
Agent and of Agent's security interest therein, and may (and upon the
instruction of the Majority Lenders, shall) collect them directly and charge the
collection costs and expenses to Borrower's Loan Account as a Revolving Loan
bearing interest at the Default Rate. Upon the occurrence of any of the events
described in clause (y) or (z) of the immediately preceding sentence and upon
Agent's request, Borrower shall execute and deliver to Agent such documents as
Agent shall require to grant Agent access to any post office box or bank in
which collections of Accounts are received.

               -----------------------------------------------
including immediately available funds received into any Deposit Account or
otherwise received by Agent on account of Accounts or as proceeds of other
Collateral, will be Agent's sole property for the benefit of Agent and the
Lenders; provided, however, unless (i) an Event of Default has occurred and is
continuing, or (ii) any Agent Advance has been made pursuant to Section
                                                                -------
2.3(b)(ii) hereof, until such Agent Advance is repaid in full, such payments and
- ----------
funds shall be transferred to Borrower's Account (or, upon Borrower's written
instructions, to such other account designated by Borrower in such instructions)
to be used for Borrower's working capital needs and general corporate purposes;
provided further, however, that immediately upon the occurrence of any event
described in the foregoing clauses (i),or (ii), Agent

tear excepted) and shall make all necessary replacements thereof.

          (b)  Additions and Deletions. Borrower shall promptly inform Agent of
               -----------------------
any material additions to or deletions from the Equipment in an amount in excess
of five hundred thousand dollars ($500,000) at any location. Borrower shall not
permit any Equipment to become a fixture with respect to real property or to
become an accession with respect to other personal property with respect to
which real or personal property Agent does not have a Lien. Borrower will not,
without Agent's prior written consent, alter or remove any identifying symbol or
number on any of Borrower's Equipment consisting of Collateral.

          (c)  Dispositions. Borrower shall not, without Agent's prior written
               ------------
consent, sell, lease as a lessor, or otherwise dispose of any of Borrower's
Equipment; provided, however, that Borrower may dispose of Equipment in the
ordinary course of business or to replace obsolete Equipment without Agent's
consent, subject to the conditions set forth in the next sentence. In the event
any of such Equipment is sold, transferred or otherwise disposed of pursuant to
the proviso contained in the immediately preceding sentence, (i) if such sale,
transfer or disposition is effected without replacement of such Equipment, or
such Equipment is replaced by Equipment leased by Borrower or by Equipment
purchased by Borrower subject to a Lien, then Borrower shall deliver all of the
cash proceeds of any such sale, transfer or disposition to Agent for application
in accordance with Section 4.4 hereof; or (ii) if such sale, transfer or
                   -----------
disposition is made in connection with the purchase by Borrower of replacement
Equipment, then Borrower shall use the proceeds of such sale, transfer or
disposition to purchase such replacement Equipment and shall deliver to Agent
written evidence of the use of the proceeds for such purchase. All replacement
Equipment purchased by Borrower shall be free and clear of all Liens, except
Agent's Lien and Permitted Liens.

     6.11 Assigned Contracts. Borrower shall fully perform all of its
          ------------------
obligations under each of the Assigned Contracts and shall enforce all of its
rights and remedies thereunder as it deems appropriate in its business judgment;
provided, however, that Borrower shall not take any actions or fail to take any
actions under any Assigned Contract that could (a) result in any violation of
any covenant of Borrower contained in this Agreement or any other Loan Document,
(b) result in a Default or Event of Default hereunder or under any other Loan
Document, (c) result in a Material Adverse Effect, (d) result in the termination
or impairment of any Material Agreement, (e) result in any Lien upon any

or remedy of Borrower thereunder; and provided further, however, that upon the
occurrence and during the continuance of a Default or an Event or Default,
Borrower shall not modify, amend, supplement, compromise, satisfy, release or
discharge any of its Assigned Contracts, any collateral securing the same, any
Person liable directly or indirectly with respect thereto or any agreement
relating to any of its Assigned Contracts or the collateral therefor, and shall
not take any actions or fail to take any actions with respect to its Assigned
Contracts which could adversely effect the full enforcement of all
indemnification rights of Borrower thereunder, in each case, without the consent
of Agent and the Majority Lenders. Borrower shall notify Agent and the Lenders
in writing, promptly after Borrower becomes aware thereof, of any event or fact
which could give rise to a claim by it for indemnification under any of its
Assigned Contracts, and shall report to Agent on all further developments with
respect thereto. Borrower shall remit directly to Agent for application to the
Obligations in such order as Agent shall determine, all amounts received by
Borrower as indemnification pursuant to its Assigned Contracts. If Borrower
shall fail after Agent's demand to comply with this Section, or if a Default or
an Event of Default then exists, Agent may, and at the direction of the Majority
Lenders Agent shall, directly enforce such right in its own or Borrower's name
and may enter into such settlements or other agreements with respect thereto as
Agent or Majority Lenders, as applicable, shall determine. In any suit,
proceeding or action brought by Agent for the benefit of the Lenders under any
Assigned Contract for any sum owing thereunder or to enforce any provision
thereof, Borrower shall indemnify and hold Agent and the Lenders harmless from
and against all expense, loss or damage suffered by reason of any defense,
setoff, counterclaims, recoupment or reduction of liability whatsoever of the
obligor thereunder arising out of a breach by Borrower of any obligation
thereunder or arising out of any other agreement, indebtedness or liability at
any time owing from Borrower to or in favor of such obligor or its successors or
assigns. All such obligations of Borrower shall be and remain enforceable only
against Borrower and shall not be enforceable against Agent or Lender.
Notwithstanding any provision hereof to the contrary, Borrower shall at all
times remain liable to observe and perform all of its duties and obligations
under its Assigned Contracts, and Agent's or Lenders' exercise of any of their
respective rights with respect to the Collateral shall not release Borrower from
any of such duties and obligations. None of Agent or Lenders shall be obligated
to perform or fulfill any of Borrower's duties or obligations under its Assigned
Contracts or to make any payment thereunder, or to make any inquiry as to the
nature or sufficiency of any payment or property received by it thereunder or
the sufficiency of performance by any party thereunder, or to present or file
any claim, or to take any action to collect or enforce any performance, any
payment of any amounts, or any delivery of any property. The undertaking of
Borrower in this Section shall survive the termination of this Agreement and the
payment of all Obligations hereunder.

               ----------------
have, for the benefit the Lenders, in addition to all other rights of Agent and
the Lenders, the rights and remedies of a secured party under all personal
property security laws, including, without limitation, the UCC; (ii) Agent may,
at any time, take possession of the Collateral and keep it on Borrower's
premises, at no cost to Agent or any Lender, or remove any part of it to such

advisable (unless the Majority Lenders shall direct otherwise), and may, if
Agent deems it reasonable, postpone or adjourn any sale of the Collateral and by
an announcement at the time and place of sale or of such postponed or adjourned
sale without giving a new notice of sale. Without in any way requiring notice to
be given in the following manner, Borrower agrees that any notice by Agent of
sale, disposition or other intended action hereunder or in connection herewith,
whether required by the UCC or otherwise, shall constitute reasonable notice to
Borrower if such notice is mailed by registered or certified mail, return
receipt requested, postage prepaid, or is delivered personally against receipt,

other than payment in full at the time of sale, no credit shall be given against
the Obligations until the appropriate Agent or Lender receives payment, and if
the buyer defaults in payment, Agent may resell the Collateral without further
notice to Borrower. In the event Agent seeks to take possession of all or any
portion of the Collateral by judicial process, Borrower irrevocably waives: (A)
the posting of any bond, surety or security with respect thereto which might
otherwise be required; (B) any demand for possession prior to the commencement
of any suit or action to recover the Collateral; and (C) any requirement that
Agent retain possession and not dispose of any Collateral until after trial or
final judgment. Borrower agrees that Agent has no obligation to preserve rights
to the Collateral or marshal any Collateral for the benefit of any Person. Agent
is hereby granted a license or other right to use, without charge, Borrower's
labels, patents, copyrights, name, trade secrets, trade names, trademarks, and
advertising matter, or any similar property, in completing production of,
advertising or selling any Collateral, and Borrower's rights under all licenses
and all franchise agreements shall inure to Agent's benefit. The proceeds of
sale shall be applied first to all expenses of sale, including attorneys' fees,
and then to the Obligations as set forth in Section 4.4 hereof. Borrower shall
                                            -----------
remain liable for any deficiency.

          (c)  Waivers. If an Event of Default occurs, Borrower hereby waives
               -------
all rights to notice and hearing prior to the exercise by Agent of Agent's
rights to repossess the Collateral without judicial process or to attach or levy
upon the Collateral without notice or hearing.

                             TERM AND TERMINATION

     12.1 Term and Termination. The term of this Agreement shall end on the
          --------------------
Termination Date. Upon instruction from the Majority Lenders, Agent may
terminate this Agreement without notice upon the occurrence of an Event of
Default. Upon the effective date of termination of this Agreement for any reason
whatsoever, all Obligations (including, without limitation, all unpaid principal
of, accrued interest on, Breakage Costs, if any, with respect to the Loans)
shall become immediately due and payable. Notwithstanding the termination of
this Agreement, until all Obligations are indefeasibly paid and performed in
full in cash, Borrower shall remain bound by the terms of this Agreement and
each of

the Loan Documents and shall not be relieved of any of its Obligations
hereunder, and Agent and the Lenders shall retain all their rights and remedies
hereunder (including, without limitation, Agent's Liens in and all rights and
remedies with respect to all then existing and after-arising Collateral).

                     AMENDMENTS; WAIVER; PARTICIPATIONS;
                            ASSIGNMENTS; SUCCESSORS

     13.1 No Waivers; Cumulative Remedies. No failure by Agent or any Lender to
          -------------------------------
exercise any right, remedy, or option under this Agreement or any Loan Document
or any present or future supplement hereto or thereto, or in any other agreement
between or among Borrower and Agent and/or any Lender, or delay by Agent or any
Lender in exercising the same, will operate as a waiver thereof. No waiver by
Agent or any Lender will be effective unless it is in writing, and then only to
the extent specifically stated. No waiver by Agent or any Lenders on any
occasion shall affect or diminish Agent's and each Lender's rights thereafter to
require strict performance by Borrower of any provision of this Agreement.
Agent's and each Lender's rights under this Agreement will be cumulative and not
exclusive of any other right or remedy which Agent or any Lender may have under
any Loan Document, under any other agreement or under applicable law.

     13.2 Amendment and Waivers.
          ----------------------

          (a)  Effective Waivers and Amendments. No amendment or waiver of any
               --------------------------------
provision of this Agreement or any other Loan Document, and no consent with
respect to any departure by Borrower therefrom, shall be effective unless the
same shall be in writing and signed by the Majority Lenders (or by Agent at the
written request of the Majority Lenders) and Borrower and then any such waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given; provided, however, that no such waiver, amendment or
consent shall, unless in writing and signed by the Requisite Lenders, Agent and
Borrower, do any of the following:

               (i)    increase or extend the Commitment of any Lender;

               (ii)   postpone or delay any date fixed by this Agreement or any

aggregate unpaid principal amount of the Loans which is required for the Lenders
or any of them to take any action hereunder;

               (v)    amend this Section or any provision of the Agreement
providing for consent or other action by the Majority Lenders or the Requisite

Loan and Security Agreement

and provided, further, that no amendment, waiver or consent shall, unless in
writing and signed by Agent, affect the rights or duties of Agent under this
Agreement or any other Loan Document; and provided, further, that the limitation
contained in clause (v) above shall not be deemed to limit the ability of Agent
to make Revolving Loans in accordance with the provisions of Section 2.3(b)
                                                             --------------
hereof; and provided further, that in no event shall any Lender be required to
advance additional moneys to increase its own Commitment unless such Lender
shall have consented to such increase.

          (b)  Amendment by Less than Unanimous Consent. Notwithstanding
               ----------------------------------------
anything to the contrary contained in Section 13.2(a) above, in the event that
                                      ---------------
Borrower requests that this Agreement or any of the other Loan Documents be
amended or otherwise modified in a manner which would require the consent of the
Requisite Lenders and such amendment or other modification is agreed to by
Borrower, the Majority Lenders and Agent then, with the consent of Borrower,
Agent and the Majority Lenders, this Agreement or such other Loan Document may
be amended without the consent of the Lender or Lenders who are unwilling to
agree to such amendment or other modification (the "Minority Lenders"), to
                                                    ----------------
provide for (i) the termination of the Commitment of each of the Minority
Lenders; (ii) the addition to this Agreement of one or more other Lenders, or an
increase in the Commitment of one or more of the Majority Lenders (it being
understood that no Lender shall be required to increase its Commitment other
than at its own election to do so), so that the Commitments after giving effect
to such amendment or other modification shall be in the same aggregate amount as
the Commitments immediately before giving effect to such amendment or other
modification; (iii) if any Loans are outstanding at the time of such amendment,
the making of such additional Revolving Loans by such new Lenders or such of the
Majority Lenders, as the case may be, as may be necessary to repay in full the
outstanding Loans of the Minority Lenders immediately before giving effect to
such amendment or other modification; and (iv) the payment of all interest, fees
and other obligations payable or accrued in favor of the Minority Lenders and
such other modifications to this Agreement or to such Loan Documents as
Borrower, Agent and the Majority Lenders may determine to be appropriate in
connection therewith.

     13.3 Assignments; Participations.
          ---------------------------

          (a)  Lender's Assignment Rights. Any Lender may, with the prior
               --------------------------
written consent of Agent and, as long as no Default or Event of Default has
occurred and is continuing, with the prior consent of Borrower (which consent
shall not be unreasonably withheld or delayed), assign and delegate to one or
more assignees (provided that no written consent of Agent or Borrower shall be
required in connection with any assignment and delegation by a Lender to an
Affiliate of such Lender) (each an "Assignee") all, or any ratable part of all,
                                    --------
of the Loans, Commitments and other rights and obligations of such Lender
hereunder, in a minimum amount of five million dollars ($5,000,000); provided,
however, that (i) no such assignment shall be permitted if the Assignee is not a
bank lender exempt from applicable usury laws (and Agent may require that such
Assignee deliver an opinion to that effect as a condition to such assignment),
and any assignment to any bank or lender which is not so exempt from applicable
usury laws shall cause the assigning Lender and the Assignee to be Defaulting
Lenders hereunder until such assignment is rescinded or such Assignee receives
its exemption from applicable usury laws; and (ii) Borrower and Agent may
continue to deal solely and directly with such Lender in connection with the
interest so assigned to an Assignee until (A) written notice of such assignment,
together with payment instructions, addresses and related information with
respect to the Assignee, shall have been given to Borrower and Agent by such
Lender and the Assignee; (B) such Lender and its Assignee shall have delivered
to Borrower and Agent an Assignment and Acceptance in form and substance
satisfactory to Agent (an "Assignment and Acceptance"); and (C) the assigning
                           -------------------------
Lender or Assignee has paid to Agent a processing fee in the amount of three
thousand five hundred dollars ($3,500). Anything contained herein to the
contrary notwithstanding, the consent of Agent and Borrower

                                      76
<PAGE>

Loan and Security Agreement

shall not be required if such assignment is to an Affiliate or Subsidiary of
such Lender or is in connection with any merger, consolidation, sale, transfer,
or other disposition of all or any substantial portion of the business or loan
portfolio of such Lender.

          (b)  Rights of Assignee. From and after the date that Agent notifies
               ------------------
the assigning Lender that an executed Assignment and Acceptance has been
received and that payment of the above-referenced processing fee has been
received, (i) the Assignee thereunder shall be a party hereto and to the extent
that rights and obligations, including, but not limited to, the obligation to
participate in credit support or other enhancement for Letters of Credit,
hereunder have been assigned to it pursuant to such Assignment and Acceptance
shall have the rights and obligations of a Lender under the Loan Documents; and
(ii) the assigning Lender shall to the extent that rights and obligations
hereunder and under the other Loan Documents have been assigned by it pursuant
to such Assignment and Acceptance relinquish its rights and be released from its
obligations under this Agreement (and in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto).

          (c)  Confirmation to Other Parties. By executing and delivering an
               -----------------------------
Assignment and Acceptance, the assigning Lender and the Assignee thereunder
confirm to and agree with each other and the other parties to this Agreement as
follows: (i) other than as provided in such Assignment and Acceptance, such
assigning Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with this Agreement or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
any other Loan Document furnished pursuant hereto; (ii) such assigning Lender
makes no representation or warranty and assumes no responsibility with respect
to the financial condition of Borrower or the performance or observance by
Borrower or any other Person of any of its obligations under this Agreement or
any other Loan Document furnished pursuant hereto; (iii) such Assignee confirms
that it has received a copy of this Agreement, together with such other
documents and information as it has deemed appropriate to make its own credit
analysis and decision to enter into such Assignment and Acceptance; (iv) such
Assignee will, independently and without reliance upon any of Agent, such
assigning Lender or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement; (v) such
Assignee appoints and authorizes Agent to take such action as agent on its
behalf and to exercise such powers under this Agreement and the other Loan
Documents as are delegated to Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; and (vi) such Assignee agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of this Agreement and the other Loan Documents are required to be
performed by it as a Lender.

          (d)  Deemed Amendment. Immediately upon each Assignee's making its
               ----------------
processing fee payment under the Assignment and Acceptance, this Agreement shall
be deemed to be amended to the extent, but only to the extent, necessary to
reflect the addition of the Assignee and the resulting adjustment of the
Commitments arising therefrom. The Commitment allocated to each Assignee shall
reduce such Commitments of the assigning Lender pro tanto.

          (e)  Participations. Any Lender, with the prior written consent of
               --------------
Agent (which consent shall not be unreasonably withheld or delayed) and pursuant
to a participation agreement in form and substance satisfactory to such Lender,
may at any time sell to one or more commercial banks, financial institutions, or
other Persons not Affiliates of Borrower (a "Participant"), participating
                                             -----------
interests in any Loans (each such participation to be in amount not less than
five million dollars ($5,000,000)), the

                                      77
<PAGE>

Loan and Security Agreement

Commitment of that Lender and the other interests of that Lender (the
"originating Lender") hereunder and under the other Loan Documents; provided,
 ------------------
however, that (i) the originating Lender's obligations under this Agreement
shall remain unchanged; (ii) the originating Lender shall remain solely
responsible for the performance of such obligations; (iii) Borrower and Agent
shall continue to deal solely and directly with the originating Lender in
connection with the originating Lender's rights and obligations under this
Agreement and the other Loan Documents; (iv) no Lender shall transfer or grant
any participating interest under which the Participant has any right to exercise
the originating Lender's right, if any, to require or approve any amendment to,
or any consent or waiver with respect to, this Agreement or any other Loan
Document, except to the extent such amendment to, or consent or waiver with
respect to, this Agreement or of any other Loan Document would (A) extend the
final maturity date of the Loans hereunder in which such Participant is
participating; (B) reduce the interest rate applicable to Loans hereunder in
which such Participant is participating; (C) release all or a material portion
of the Collateral (except to the extent expressly provided herein or in any of
the other Loan Documents) supporting the Loans hereunder in which such
Participant is participating; (D) postpone the payment of, or reduce the amount
of, the interest or fees payable to such Participant; (E) change the amount or
due dates of scheduled principal repayments or prepayments or premiums in
respect of Loans hereunder in which such Participant is participating; (F)
increase the Maximum Amount above forty million dollars ($40,000,000); or (G)
increase the advance rate with respect to Revolving Loans in which such
Participant is participating, including the restoration of an advance rate after
the reduction thereof, provided that, the limitation contained in this clause
(G) shall not be deemed to limit the ability of Agent to make Revolving Loans in
accordance with the provisions of Section 2.3(b) hereof; and (v) all amounts
                                  --------------
payable by Borrower hereunder shall be determined as if such originating Lender
had not sold such participation; except that, if amounts outstanding under this
Agreement are due and unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall be deemed to have the right of setoff in respect of its participating
interest in amounts owing under this Agreement to the same extent as if the
amount of its participating interest were owing directly to it as a Lender under
this Agreement.

          (f)  Pledge in Favor of Federal Reserve Bank. Notwithstanding any
               ---------------------------------------
other provision in this Agreement, any Lender may at any time create a security
interest in, or pledge, all or any portion of its rights under and interest in
this Agreement in favor of any Federal Reserve Bank in accordance with
Regulation A of the Federal Reserve Bank or U.S. Treasury Regulation 31 CFR (S)
203.14, and such Federal Reserve Bank may enforce such pledge or security
interest in any manner permitted under applicable law.

     13.4  Additional Commitments. If (i) on the Closing Date the aggregate
           ----------------------
amount of the Commitments is less than forty million dollars ($40,000,000), and
(ii) subsequent to the Closing Date, additional Commitments satisfactory to
Agent have been obtained as contemplated by the terms hereof ("Additional
                                                               ----------
Commitments"), then each Lender providing an Additional Commitment shall execute
- -----------
and deliver a signature page hereto setting forth such Lender's Commitment and
wire transfer information and simultaneously therewith shall become a party to
this Agreement and have all of the rights and obligations of a Lender under this
Agreement and the other Loan Documents. If and when any such Additional
Commitments are so made, the Maximum Amount shall be automatically adjusted in
accordance with the definition thereof.

                                     AGENT

     14.1  Appointment and Authorization. Each Lender hereby designates and

appoints Union Bank of California, N.A., as its Agent under this Agreement and
the other Loan Documents and each Lender hereby irrevocably authorizes Agent to
take such action on its behalf under the provisions of this Agreement and each
other Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto. Agent
agrees to act as such on the express conditions contained in this Article 14.
                                                                  ----------
The provisions of this Article 14 are solely for the benefit of Agent and the
                       ----------
Lenders and Borrower shall have no rights as a third party beneficiary of any of
the provisions contained herein. Notwithstanding any provision to the contrary
contained elsewhere in this Agreement or in any other Loan Document, Agent shall
have no duties or responsibilities, except those expressly set forth herein, nor
shall Agent have or be deemed to have any fiduciary relationship with any
Lender, or each other, and no implied covenants, functions, responsibilities,
duties, obligations or liabilities shall be read into this Agreement or any
other Loan Document or otherwise exist against Agent. Except as expressly
otherwise provided in this Agreement, Agent shall have and may use its sole
discretion with respect to exercising or refraining from exercising any
discretionary rights or taking or refraining from taking any actions which Agent
is expressly entitled to take or assert under this Agreement and other Loan
Documents, including, without limitation, making the determinations contemplated
in Section 2.2(a) and Section 2.2(c).
   --------------     --------------

     14.2  Delegation of Duties. Agent may execute any of its duties under this
           --------------------
Agreement or any other Loan Document by or through Agent-Related Persons,
employees, agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. Agent shall not be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that Agent selects as long as such selection was made without gross negligence
or willful misconduct.

     14.3  Liability of Agent. None of Agent-Related Persons shall (a) be liable
           ------------------
for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (b) be responsible in any manner to any of the Lenders for any recital,
statement, representation or warranty made by Borrower, any Affiliate of
Borrower, or any director, officer, employee or representative thereof,
contained in this Agreement or in any other Loan Document, or in any Borrowing
Base Certificate, Loan Request, certificate, report, statement or other document
referred to or provided for in, or received by Agent under or in connection
with, this Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement, any other Loan
Document, any Borrowing Base Certificate or any Loan Request, or for any failure
of Borrower or any other party to any Loan Document to perform its obligations
hereunder or thereunder. No Agent-Related Person shall be under any obligation
to any Lender to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, and No-Agent-Related Person shall be under any obligation
to inspect the properties, books or records of Borrower or any of Borrower's
Subsidiaries or Affiliates.

     14.4  Reliance by Agent.
           -----------------

           (a)  Reliance. Agent shall be entitled to rely, and shall be fully
                --------
protected in relying, upon any Borrowing Base Certificate, Loan Request,
writing, resolution, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, statement or other document or

                                      79

Loan and Security Agreement

conversation believed by it to be genuine and correct and which appear to have
been signed, sent or made by the proper Person or Persons, and upon advice and
statements of legal counsel (including counsel to Borrower), independent
accountants and other experts selected by Agent. Agent shall be fully justified
in failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Majority Lenders as it deems appropriate and until such instructions are
received Agent shall act, or refrain from acting, as it deems advisable so long
as it is not grossly negligent or guilty of willful misconduct. Upon the written
request of the Majority Lenders, Agent agrees that it promptly will make demand
upon Borrower pursuant to Section 4.1 for repayment of the amount by which the
                          -----------
Revolving Loan Usage exceeds the Availability. If Agent so requests, Agent shall
first be indemnified to its reasonable satisfaction by the Lenders, in
proportion to their Pro Rata Shares, against any and all liability and expense
which may be incurred by it by reason of taking or continuing to take any such
action. Agent shall in all cases be fully protected in acting, or in refraining
from acting, under this Agreement or any other Loan Document in accordance with
a request or consent of the Majority Lenders (or, if a matter requires the
request or consent of the Requisite Lenders, at the request or with the consent
of the Requisite Lenders) and such request and any action taken or failure to
act pursuant thereto shall be binding upon all of the Lenders.

           (b)  Deemed Consent. For purposes of determining compliance with the
                --------------
conditions specified in Section 10.1, each Lender that has executed this
                        ------------
Agreement shall be deemed to have consented to, approved or accepted each
document or other matter either sent by Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to the Lender.

     14.5  Notice of Default. Agent shall not be deemed to have knowledge or
           -----------------
notice of the occurrence of any Default or Event of Default, except with respect
to defaults in the payment of principal, interest and fees required to be paid
to Agent for the account of the Lenders, unless Agent shall have received
written notice from a Lender or Borrower referring to this Agreement, describing
such Default or Event of Default and stating that such notice is a "notice of
default." Agent promptly will notify the Lenders of its receipt of any such
notice. Agent shall take such action with respect to any Default or Event of
Default as may be requested by the Majority Lenders in accordance with Article
                                                                       -------
11; provided, however, that unless and until Agent has received such a request,
- --
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable.

     14.6  Credit Decision. Each Lender acknowledges that none of Agent-Related
           ---------------
Persons has made any representation or warranty to it, and that no act by Agent
hereinafter taken, including any review of the affairs of Borrower , shall be
deemed to constitute any representation or warranty by Agent-Related Persons to
any Lender. Each Lender represents to Agent that it has, independently and
without reliance upon Agent-Related Persons and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and
other condition and creditworthiness of Borrower, and all applicable bank
regulatory laws relating to the transactions contemplated hereby, and made its
own decision to enter into this Agreement and to extend credit to Borrower. Each
Lender also represents that it will, independently and without reliance upon
Agent-Related Persons and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of Borrower. Except for notices,
reports and other documents expressly herein required to be furnished to the
Lenders by Agent, Agent shall have no duty

                                      80
<PAGE>

Loan and Security Agreement

or responsibility to provide any Lender with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of Borrower which may come into the possession of
any of Agent-Related Persons.

     14.7  Indemnification. Whether or not the transactions contemplated hereby
           ---------------
are consummated, the Lenders shall indemnify upon demand each of Agent-Related
Persons (to the extent not reimbursed by or on behalf of Borrower and without
limiting the obligation of Borrower to do so), in proportion to their Pro Rate
Shares, from and against any and all Indemnified Liabilities (as defined in
Section 15.9 hereof); provided, however, that no Lender shall be liable for the
- ------------
payment to any Agent-Related Person of any portion of such Indemnified
Liabilities resulting solely from such Person's gross negligence or willful
misconduct. Without limitation of the foregoing, each Lender shall reimburse
Agent upon demand for its Pro Rata Share of any costs or out-of-pocket expenses
(including reasonable Attorney Costs) incurred by Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings or otherwise) of,
or legal advice in respect of rights or responsibilities under, this Agreement,
any other Loan Document or any document contemplated by or referred to herein,
to the extent that Agent is not reimbursed for such expenses by or on behalf of
Borrower; provided, however, that to the extent indemnification payments made by
the Lenders pursuant to this Section 14.7 are subsequently recovered from or for
                             ------------
the account of Borrower, Agent shall promptly refund such previously paid
indemnification payments to the Lenders entitled thereto. The undertaking in
this Section shall survive the payment of all Obligations hereunder and the
resignation or replacement of Agent.

     14.8  Union Bank of California N.A., in its Individual Capacity. Union Bank
           ---------------------------------------------------------
of California, N.A, and any Agent-Related Person may make loans to, issue
Letters of Credit for the account of, accept deposits from, acquire equity
interests in, purchase receivables of, act as agent or administrative agent for
and generally engage in any kind of banking, trust, financial advisory,
underwriting or other business with Borrower, any of Borrower's Subsidiaries or
Affiliates or any Lender as though Union Bank of California, N.A, were not Agent
hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, Union Bank of California, N.A, or
Agent-Related Persons may receive information regarding Borrower or its
Affiliates that is subject to confidentiality obligations in favor of Borrower
or such other Person and that prohibit the disclosure of such information to the
Lenders, and the Lenders acknowledge that Agent shall be under no obligation to
provide such information to them. With respect to its Loans, Union Bank of
California, N.A, shall have the same rights and powers under this Agreement as
any other Lender and may exercise the same as though it were not Agent, and the
terms "Lender" and "Lenders" include Union Bank of California, N.A, in its
individual capacity.

     14.9  Successor Agent. Agent may resign as Agent upon thirty (30) days'
           ---------------
prior notice to the Lenders. If Agent resigns under this Agreement, the Majority
Lenders shall appoint from among the Lenders a successor Agent for the Lenders.
If no successor agent is appointed prior to the effective date of the
resignation of Agent, the resigning Agent may appoint, after consulting with the
Lenders and Borrower, a successor agent from among the Lenders. Upon the
acceptance of its appointment as a successor agent hereunder, such successor
agent shall succeed to all the rights, powers and duties of the retiring Agent,
as the case may be, and the term "Agent" shall mean such successor agent and the
retiring Agent's appointment, powers and duties (but not any liabilities
incurred prior thereto) as Agent, as appropriate, shall be terminated. After any
retiring Agent's resignation hereunder as Agent, Agent shall mean such successor
agent and the retiring Agent's appointment, powers and duties as such Agent
shall be terminated. After any retiring Agent's resignation as Agent, the
provisions of this Article 14 shall

                                      81
<PAGE>

Loan and Security Agreement

inure to its benefit as to any actions taken or omitted to be taken by it while
it was such Agent under this Agreement. If no successor agent has accepted
appointment as Agent by the date which is thirty (30) days following the
retiring Agent's notice of resignation, the retiring Agent's resignation shall
nevertheless thereupon become effective and the Lenders shall perform all the
duties of Agent hereunder and under the other Loan Documents until such time, if
any, as the Majority Lenders appoint a successor Agent, in each instance, as
provided for above.

     14.10  Withholding Tax.
            ---------------

            (a)  Foreign Lender. If any Lender is a "foreign corporation,
                 --------------
partnership or trust" within the meaning of the Code and such Lender claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441 or
1442 of the Code, such Lender agrees with and in favor of Agent, to deliver to
Agent:

                 (i)   if such Lender claims an exemption from, or a reduction
of, withholding tax under a United States tax treaty, properly completed IRS
Forms 1001 and W-8 before the payment of any interest in the first calendar year
during which interest may be paid under this Agreement;

                 (ii)  if such Lender claims that interest paid under this
Agreement is exempt from United States withholding tax because it is effectively
connected with a United States trade or business of such Lender, two (2)
properly completed and executed copies of IRS Form 4224 before the payment of
any interest is due in the first taxable year of such Lender and in each
succeeding taxable year of such Lender during which interest may be paid under
this Agreement, and IRS Form W-9; and

                 (iii) such other form or forms as may be required under the
Code or other laws of the United States as a condition to exemption from, or
reduction of, United States withholding tax.

Such Lender agrees to promptly notify Agent of any change in circumstances which
would modify or render invalid any claimed exemption or reduction.

            (b)  Assignments or Participations by 1001 Lender. If any Lender
                 --------------------------------------------
claims exemption from, or reduction of, withholding tax under a United States
tax treaty by providing IRS Form 1001 and such Lender sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of
Borrower to such Lender, such Lender agrees to notify Agent of the percentage
amount in which it is no longer the beneficial owner of Obligations of Borrower
to such Lender. To the extent of such percentage amount, Agent will treat such
Lender's IRS Form 1001 as no longer valid.

            (c)  Assignment or Participation by 4224 Lender. If any Lender
                 ------------------------------------------
claiming exemption from United States withholding tax by filing IRS Form 4224
with Agent sells, assigns, grants a participation in, or otherwise transfers all
or part of the Obligations of Borrower to such Lender, such Lender agrees to
undertake sole responsibility for complying with the withholding tax
requirements imposed by Sections 1441 and 1442 of the Code.

            (d)  Reduction in Withholding Tax. If any Lender is entitled to a
                 ----------------------------
reduction in the applicable withholding tax, Agent may withhold from any
interest payment to such Lender an amount equivalent to the applicable
withholding tax after taking into account such reduction. If the forms or other
documentation required by paragraph (a) of this Section are not delivered to
Agent, then Agent

                                      82
<PAGE>

Loan and Security Agreement

may withhold from any interest payment to such Lender not providing such forms
or other documentation an amount equivalent to the applicable withholding tax.

            (e)  Claim of Improper Withholding. If the IRS or any other
                 -----------------------------
Governmental Authority of the United States or other jurisdiction asserts a
claim that Agent did not properly withhold tax from amounts paid to or for the
account of any Lender (because the appropriate form was not delivered, was not
properly executed, or because such Lender failed to notify Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason) such Lender shall indemnify each of
Agent fully for all amounts paid, directly or indirectly, by it as tax or
otherwise, including penalties and interest, and including any taxes imposed by
any jurisdiction on the amounts payable to Agent under this Section, together
with all costs and expenses (including Attorney Costs). The obligation of the
Lenders under this paragraph shall survive the payment of all Obligations and
the resignation or replacement of Agent.

     14.11  Collateral Matters.
            ------------------

            (a)  Release of Agent's Lien. The Lenders hereby irrevocably
                 -----------------------
authorize Agent, at its option and in its discretion to release any Agent's Lien
upon any Collateral: (i) upon the termination of the Commitments and payment and
satisfaction in full by Borrower of all Loans and reimbursement obligations in
respect of Letters of Credit, and the termination of all outstanding Letters of
Credit (whether or not any of such obligations are due) and all other
Obligations; (ii) constituting property being sold or disposed of by Borrower if
Borrower certifies to Agent that the sale or disposition is made in compliance
with Section 9.8 (and Agent may rely conclusively on any such certificate,
     -----------
without further inquiry); (iii) constituting property leased to Borrower under a
lease which has expired or been terminated in a transaction permitted under this
Agreement; or (iv) otherwise constituting property having a value not greater
than five hundred thousand dollars ($500,000). Except as expressly provided
above, Agent will not release any of Agent's Liens upon the Collateral without
the prior written authorization of the Majority Lenders; provided, further, that
Agent shall not release Agent's Liens on Collateral having a value in the
aggregate in excess of one million dollars ($1,000,000) without the prior
written authorization of the Requisite Lenders. Upon request of Agent or
Borrower at any time, the Lenders will confirm in writing Agent's authority to
release any Agent's Liens upon particular types or items of Collateral.

            (b)  Execution of Releases. Upon receipt by Agent of any
                 ---------------------
authorization required pursuant to Section 14.11(a) from (i) Agent, and (ii) the
                                   ----------------
Majority Lenders or Requisite Lenders, as applicable, of Agent's authority to
release any Agent's Liens upon particular types or items of Collateral, and upon
at least five (5) Business Days' prior written request by Borrower, Agent shall
(and is hereby irrevocably authorized by the Lenders to) execute such documents
as may be necessary to evidence the release of Agent's Liens upon such
Collateral; provided, however, that (A) Agent shall not be required to execute
any such document on terms which, in Agent's opinion, would expose Agent to
liability or create any obligation or entail any consequence other than the
release of such Liens without recourse or warranty; and (B) such release shall
not in any manner discharge, affect or impair the Obligations or any Liens
(other than those expressly being released) upon (or obligations of Borrower in
respect of) all interests retained by Borrower, including, without limitation,
the proceeds of any sale, all of which shall continue to constitute part of the
Collateral.

            (c)  No Obligation. Agent shall have no obligation whatsoever to any
                 -------------
of the Lenders to assure that the Collateral exists or is owned by Borrower or
is cared for, protected or insured or has been encumbered, or that Agent's Liens
have been properly or sufficiency or lawfully created,

                                      83
<PAGE>

Loan and Security Agreement

perfected, protected or enforced or are entitled to any particular priority, or
to exercise at all or in any particular manner or under any duty of care,
disclosure or fidelity, or to continue exercising, any of the rights,
authorities and powers granted or available to Agent pursuant to any of the Loan
Documents, it being understood and agreed that in respect of the Collateral, or
any act, omission or event related thereto, subject to the terms and conditions
contained herein, Agent may act in any manner it may deem appropriate, in its
reasonable discretion and that Agent shall have no other duty or liability
whatsoever to any Lender as to any of the foregoing, except as otherwise
specifically provided herein.

     14.12  Restrictions on Actions by Lenders; Sharing of Payments.
            -------------------------------------------------------

            (a)  Setoffs. Notwithstanding any provision to the contrary in
                 -------
Section 15.13 hereof, as between Agent and the Lenders only (and without any
- -------------
intention to allow Borrower any right or benefit under this paragraph), each of
the Lenders agrees that it shall not, without the express written consent of
Agent, and that it shall, to the extent it is lawfully entitled to do so, upon
the request of Agent, set off against the Obligations, any amounts owing by such
Lender to Borrower or any accounts of Borrower now or hereafter maintained with
Agent or such Lender, as the case may be. Each of the Lenders further agrees
that it shall not, unless specifically requested to do so by Agent, take or
cause to be taken any action, including, the commencement of any legal or
equitable proceedings, to foreclose any Lien on, or otherwise enforce any
security interest in, any of the Collateral, the purpose of which is, or could
be, to give such Lender any preference or priority against the other Lenders
with respect to the Collateral.

            (b)  Excess Proceeds. If at any time or times any Lender shall
                 ---------------
receive (i) by payment, foreclosure, setoff or otherwise, any proceeds of
Collateral or any payments with respect to the Obligations of Borrower to such
Lender arising under, or relating to, this Agreement or the other Loan
Documents, except for any such proceeds or payments received by such Lender from
Agent pursuant to the terms of this Agreement; or (ii) payments from Agent in
excess of such Lender's Pro Rata Share of all such distributions by Agent, such
Lender shall promptly (A) turn the same over to Agent, in kind, and with such
endorsements as may be required to negotiate the same to Agent, or in same day
funds, as applicable, for the account of all of the Lenders and for application
to the Obligations in accordance with the applicable provisions of this
Agreement; or (B) purchase, without recourse or warranty, an undivided interest
and participation in the Obligations owed to the other Lenders so that such
excess payment received shall be applied ratably as among the Lenders in
proportion to their respective Pro Rata Shares; provided, however, that if all
or part of such excess payment received by the purchasing party is thereafter
recovered from it, those purchases of participations shall be rescinded in whole
or in part, as applicable, and the applicable portion of the purchase price paid
therefor shall be returned to such purchasing party, but without interest except
to the extent that such purchasing party is required to pay interest in
connection with the recovery of the excess payment.

     14.13  Agency for Perfection. Each Lender hereby appoints Agent and each
            ---------------------
other Lender as agent for the purpose of perfecting Agent's Liens and Lenders'
security interest in assets which, in accordance with Article 9 of the UCC, can
be perfected only by possession. Should any Lender obtain possession of any such
Collateral, such Lender shall notify Agent thereof and, promptly upon Agent's
request therefor, shall deliver such Collateral to Agent or in accordance with
Agent's instructions.

     14.14  Payments. All payments to be made by any Lender to Agent shall be
            --------
made by bank wire transfer or internal transfer of immediately available funds
to:

agrees and acknowledges that Agent or other party performing any audit,
examination or review will inspect only specific information regarding Borrower

            (c)  Confidentiality. Each Lender expressly agrees to keep all
                 ---------------
reports prepared or reviewed by Agent and all Borrowing Base Certificates
confidential in accordance with Section 15.14 hereof.
                                -------------

agrees: (i) to hold Agent, any other Lender and any Agent-Related Person which
has prepared, reviewed or approved any report, Borrowing Base Certificate or

                                 MISCELLANEOUS

     15.1  Cumulative Remedies; No Prior Recourse to Collateral. The enumeration
           ----------------------------------------------------
herein of Agent's and each Lender's rights and remedies is not intended to be
exclusive, and such rights and remedies are in addition to and not by way of
limitation of any other rights or remedies that Agent and Lenders may have under
the UCC or other applicable law. Each of Agent and the Lenders shall have the
right, in their sole discretion, to determine which rights and remedies are to
be exercised and in which order. The exercise of one right or remedy shall not
preclude the exercise of any others, all of which shall be cumulative. Agent and
the Lenders may, without limitation, proceed directly against Borrower to
collect the Obligations without any prior recourse to the Collateral. No failure
to exercise and no delay in exercising, on the part of Agent or any Lender, any
right, remedy, power or privilege hereunder, shall operate as a waiver thereof;
nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege.

     15.2  Limitation of Liability. Borrower agrees that it will not assert
           -----------------------
against Agent or any Lender any claim for consequential, incidental, special or
punitive damages in connection with this Agreement or any of the other Loan
Documents or the transactions contemplated hereby or thereby.

Documents shall survive the execution, delivery, and acceptance hereof and
thereof by the parties, notwithstanding any investigation by Agent or any
Lenders or their respective agents.

     15.4  Other Security and Guaranties. Agent may, without notice or demand
           -----------------------------
and without affecting Borrower's obligations hereunder, from time to time: (a)
take from any Person and hold collateral (other than the Collateral) for the
payment of all or any part of the Obligations and exchange, enforce or release
such collateral or any part thereof; and (b) accept and hold any endorsement or
Guaranty of payment of all or any part of the Obligations and release or
substitute any such endorser or guarantor, or any Person who has given any Lien
or other collateral as security for the payment of all or any part of the
Obligations, or any other Person in any way obligated to pay all or any part of

Executive in an amount to be determined prior to each fiscal year by the Board
and Executive. The Annual Bonus may be structured, as agreed upon by Executive

     vehicle on company business, during the Employment Period, the Company
     shall provide to Executive a reasonably priced car consistent with the
     Company's past practice. Such company car shall be available for

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

          (a) Executive acknowledges that all Work Product is the exclusive
property of the Company. Executive hereby assigns all right, title and interest
in and to such Work Product to the Company. Any copyrightable work prepared in

rights comprised in the copyright therein.

include, any invention that Executive developed entirely on his own time without
using the Company's equipment, supplies, facilities, or trade secret information
except for those inventions that either: (i) relate at the time of conception or
reduction to practice of the invention to the Company's or any Subsidiary's
business, or to the actual or demonstrably anticipated research or development
of the Company or any Subsidiary; or (ii) result from any work performed by
Executive for the Company or any Subsidiary. Set forth on the attached "Excluded
                                                                        --------
Inventions Schedule" are the inventions Executive believes meet the criteria for
- -------------------
exclusion set forth above. Executive agrees to promptly advise the Company in
writing of any inventions developed after the Effective Date which Executive
believes meet the criteria for exclusion set forth above.

          (c) Executive shall promptly and fully disclose all Work Product to
the Company and shall cooperate and perform all actions reasonably requested by
the Company (whether during or after the Employment Period) to establish,
confirm and protect the Company's right, title and interest in such Work
Product. Without limiting the generality of the foregoing, Executive agrees to
assist the Company, at the Company's expense, to secure the Company's rights in
the Work Product in any and all countries, including the execution of all
applications and all other instruments and documents which the Company shall
deem necessary in order to apply for and obtain rights in such Work Product and
in order to assign and convey to the Company the sole and exclusive right, title
and interest in and to such Work Product. If the Company is unable because of
Executive's mental or physical incapacity or for any other reason (including
Executive's refusal to do so after request therefor is made by the Company) to
secure Executive's signature to apply for or to pursue any application for any
United States or foreign patents or copyright registrations coveting Work
Product belonging to or assigned to the Company pursuant to paragraph 7(a)
above, then Executive hereby irrevocably designates and appoints the Company and
its duly authorized officers and agents

                                      -5-
<PAGE>

as Executive's agent and attorney-in-fact to act for and in Executive's behalf
and stead to execute and file any such applications and to do all other lawfully
permitted acts to further the prosecution and issuance of patents or copyright
registrations thereon with the same legal force and effect as if executed by
Executive. Executive agrees not to apply for or pursue any application for any
United States or foreign patents or copyright registrations coveting any Work
Product other than pursuant to this paragraph in circumstances where such
patents or copyright registrations are or have been or are required to be
assigned to the Company.

          8.  Delivery of Materials Upon Termination of Employment. As requested
              ----------------------------------------------------
by the Company upon the termination of Executive's employment with the Company
for any reason, Executive shall promptly deliver to the Company all copies and
embodiments, in whatever form, of all Confidential Information and Work Product
in Executive's possession or within his control irrespective of the location or
form of such material and, if requested by the Company, shall provide the
Company with written confirmation that all such materials have been delivered to
the Company.

          9.  Subsequent Inventions. Executive understands and agrees that all
              ---------------------
Intellectual Property Rights made, conceived, developed, or reduced to practice
by Executive, either alone or jointly with others, shall be disclosed to the
Company by Executive for six (6) months following the termination of the
Employment Period. Employee further agrees that all Intellectual Property Rights
made, conceived, developed or reduced to practice within six (6) months
following such termination shall be presumed to have been conceived during
Executive's employment with the Company and with the use of the Company's
Confidential Information, but such presumption may be overcome by Executive by a
showing that such Intellectual Property Rights were conceived after the
Employment Period and without the use of any such Confidential Information. In
the event Executive is not able to rebut such presumption and prove that such
Intellectual Property Rights were conceived after the Employment Period and
without the use of Confidential Information, Executive agrees to assign all
right, title and interest in such Intellectual Property Rights to the Company.

          10. Disclosure. Following the termination of the Employment Period,
              ----------
Executive shall communicate the restrictions contained in this Agreement to any
Person he intends to be employed by, provide consulting services to or otherwise
represent. Executive hereby consents to the Company's communication of the
restrictions contained in this Agreement to any such Person.

          11. Enforcement Remedies.
              --------------------

          (a) If, at the time of enforcement of the covenants contained in
paragraphs 6, 7, 8, 9 or 10 (the "Protective Covenants"), a court shall hold
                                  --------------------
that the duration or scope stated therein are unreasonable under circumstances
then existing, the parties hereto agree that the maximum duration or scope
reasonable under such circumstances shall be substituted for the stated duration
or scope and that the court shall be allowed to revise the restrictions
contained therein to cover the maximum period or scope permitted by law.
Executive has consulted legal counsel regarding the Protective Covenants and
based on such consultation has determined and hereby acknowledges that

                                      -6-
<PAGE>

the Protective Covenants are reasonable in terms of duration and scope and are
necessary to protect the goodwill of the Company's business and the Confidential
Information. Executive further agrees that the Protective Covenants were a
material inducement to certain investors of the Company to enter into the Merger
Agreement and consummate the transactions contemplated thereby, and such
investors would not obtain the benefit of the bargain as set forth in the Merger
Agreement and the other agreements contemplated thereby if Executive breached or
challenged the validity of any of the Protective Covenants.

          (b)  If Executive breaches, or threatens to commit a breach of, any of
the Protective Covenants, the Company shall have the following rights and
remedies, each of which rights and remedies shall be independent of the others
and severally enforceable, and each of which is in addition to, and not in lieu
of, any other rights and remedies available to the Company at law or in equity:

               (i)  the right and remedy to have the Protective Covenants
     specifically enforced by any court of competent jurisdiction (without the
     need to post a bond or other security), it being agreed that any breach or
     threatened breach of the Protective Covenants would cause irreparable
     injury to the Company and that money damages would not provide an adequate
     remedy to the Company; and

               (ii) the right and remedy to require Executive to account for and
     pay over to the Company any profits, monies, accruals, increments or other
     benefits derived or received by Executive as the result of any
     transaction(s) constituting a breach of the Protective Covenants.

          (c)  In the event of any breach or violation by Executive of any of
the Protective Covenants, the time period of such covenant with respect to
Executive (to the extent such covenant is limited in duration) shall be tolled
until such breach or violation is resolved.

Executive and the Company acknowledge and agree that the Company's sole remedy
for such breach shall be the termination of the Severance Payments otherwise

                                                   ____, 1999


Dear Safeguard Stockholder:

     As you may know, we are undertaking an initial public offering of the
common stock of Pac-West Telecomm, Inc. We are permitting Safeguard Scientifics
to use its Directed Share Subscription Program so that we may offer you the
opportunity to buy our common stock at our initial public offering price. We
will be offering ________ shares and Safeguard Scientifics will be
offering _______ shares under the program.

     Set forth below is a detailed description of how the program will work in
connection with our offering.  Please review this description and the attached
prospectus carefully in deciding whether or not you wish to invest.

Who can subscribe

     Only holders of 100 or more shares of Safeguard common stock as of
______ __, 1999 are eligible to purchase shares of our common stock in the
program. Holders of fewer than 100 Safeguard shares will not be eligible to
participate in this program.

You may not transfer your subscription offer

     The offer to purchase shares in this program may only be transferred by
involuntary operation of law such as death or certain dissolutions. Number of
shares for which you may subscribe

     To determine how many shares of our common stock you are eligible to
purchase, divide the number of shares of Safeguard common stock that you owned
as of ______ __, 1999 by 10 and round up to the nearest whole number. For
example, if you held between 991 and 1,000 shares of Safeguard common stock as
of this date, you may subscribe for 100 shares of our common stock. You would
have to have had at least 100 shares of Safeguard common stock to be eligible
to subscribe for 10 shares of our common stock. You may not subscribe for a
fractional share of our common stock.

Minimum Subscription Size

     The minimum subscription that we will accept for any account is for 10
shares of our common stock. Therefore, holders of fewer than 100 shares of
Safeguard common stock as of ______ __, 1999 will not be able to purchase our
shares under the program. This limit applies to each of your accounts, not the
aggregate of all of your accounts. If as of August 31, 1999 you held 50 shares
of Safeguard common stock in one account and another 50 shares in a different
account, we will not consider you to be the owner of 100 shares of Safeguard
common stock. Since none of your accounts contained at least 100 shares of
Safeguard common stock, you would not be eligible to subscribe.

     You are under no obligation to subscribe, but if you subscribe for any
shares it must be for at least 10 shares in each account.  For example, if
you held 750 shares of Safeguard common stock in a single account as of
______ __, 1999 and you choose to purchase our shares under the program, you may
purchase between 10 and 75 shares.

Subscription Price

     The price per share under the program will be the same price that all
investors will pay in our initial public offering.  The price per share in the
initial public offering will be determined by negotiations between us and the
underwriters of our offering.  The factors that we expect to consider in these
negotiations are described in the
<PAGE>

attached prospectus under the heading "Underwriting." We currently anticipate
that the offering price will be between $_______ and $______ per share.
Safeguard will inform you of the initial public offering price as described
below under "How to Subscribe."

Stock Purchase Agreement with Safeguard Scientifics

     We intend to enter into a Stock Purchase Agreement with Safeguard. This
agreement will provide that if all ___________ of the shares offered by Pac-West
under the program are not purchased by Safeguard stockholders, then Safeguard
will purchase the remaining shares at our initial public offering price.
Safeguard will be able to transfer all or part of its obligation to purchase
these remaining shares to third parties.

How to Subscribe

     TO PURCHASE SHARES UNDER THE PROGRAM, YOU MUST ADHERE TO THE FOLLOWING
PROCEDURES:

     .  Subscriptions and payments will only be accepted after we have
        determined our initial public offering price. Any subscriptions or
        payments received before then will be returned to you. Once a
        subscription and payment have been received and accepted, you may not
        revoke your subscription. We expect to determine the initial public
        offering price in _________ 1999, but various factors could hasten or
        delay us. We will close the initial public offering and stop accepting
        subscriptions four business days after we determine the initial public
        offering price.

     .  Time will not permit us to notify you directly of our initial public
        offering price and closing date. Instead, Safeguard will take the
        following actions:

        .  publicize the offering price and the closing date on its Web site
           (www.safeguard.com) and through a press release;

        .  through its Web site, provide you with an opportunity to request
           e-mail notification (either directly to you or your designated
           representative);

        .  make every effort to notify each broker, bank, trust company or other
           nominee that holds shares on behalf of Safeguard stockholders of the
           offering price and closing date; and

        .  make available an automated investor relations line (888-SFE-1200) on
           a 24-hour basis through which you can listen to the text of the press
           release or request a faxed copy.

        You will have to monitor these media to know when to place your order
        and deliver payment.

        Also, if you do not hold your Safeguard shares directly, you will need
        to keep in close contact with your broker, bank, trust company or other
        nominee that holds your Safeguard shares on your behalf since they will
        need to process the subscription for our shares and payment on your
        behalf.

 *  We will stop accepting orders under the program at 5:00 p.m. New York
    City time on the fourth business day after we determine the initial
    public offering price. Subscriptions and payments that have not been
    received by ChaseMellon Shareholder Services, L.L.C. by this deadline

    offering price on a Thursday, ChaseMellon must receive all orders and
    payments by 5:00 p.m. New York City time on the following Wednesday.

<PAGE>

        .  If you hold your Safeguard shares through a broker, bank, trust
           company or other nominee

           We will provide to each broker, bank, trust company, and other
           nominee who holds Safeguard shares for the account of other persons
           copies of the preliminary and final prospectus.  Each of those
           entities will be responsible for providing you with a copy of the
           preliminary and final prospectus.  Subscription forms will not be
           distributed to Safeguard shareholders who hold their shares in a
           brokerage account since the subscription offer will be distributed to
           your account electronically.

           After we determine the initial public offering price, you will have
           to contact the broker, bank, trust company or other nominee that
           holds your Safeguard shares if you wish to place an order and arrange
           for payment.  ChaseMellon Shareholder Services will be unable to
           directly accept your subscription and payment.  All subscriptions and
           payments must be submitted through the broker, bank, trust company or
           other nominee that holds your Safeguard shares.

           We caution you that brokers and other nominees will require some time
           to process subscriptions from Safeguard stockholders.  Therefore,
           they most likely will stop accepting subscriptions earlier than the
           fourth business day after we determine the initial public offering
           price.

     .  Safeguard will decide all questions as to the validity, form and
        eligibility (including times of receipt, beneficial ownership and
        compliance with minimum exercise provisions). Safeguard also will
        determine the acceptance of subscriptions and the aggregate price.
        Alternative, conditional or contingent subscriptions will not be
        accepted. Safeguard reserves the absolute right to reject any
        subscriptions not properly submitted. In addition, Safeguard may reject
        any subscription if the acceptance of the subscription would be
        unlawful. Safeguard also may waive any irregularities or conditions in
        the subscription for our shares, and Safeguard's interpretation of the
        terms and conditions of the program will be final and binding.

     .  We are not obligated to give you notification of defects in your
        subscription. We will not consider a subscription to be made until all
        defects have been cured or waived. If your subscription is rejected,
        your payment of the exercise price will be promptly returned by
        ChaseMellon.

     .  Sales under the directed share subscription program will close on the
        same business day as the closing of the sale of the other shares offered
        to the public. If you purchase your shares through a broker, bank, trust
        company or similar nominee, we expect that your purchase will be
        reflected in your account with the nominee as soon as practicable after
        the expiration of the directed share subscription program. Otherwise,
        ChaseMellon will mail a stock certificate to you as soon as practicable
        after the expiration of the directed share subscription program.

Cancellation of Initial Public Offering

     We may cancel our initial public offering at any time up until the closing.
If the initial public offering is canceled, Safeguard will publicize the
cancellation on its Web site and through a press release. The program gives you
no rights to purchase shares of our common stock if we cancel our initial public
offering and any funds previously submitted by you will be returned promptly.
Safeguard and/or Pac-West also may cancel or modify, in whole or in part, the
directed share subscription program.

Federal Tax Consequences

     We believe that you will not be considered to have received a taxable
distribution of property as a result of your having the opportunity to
participate in this offering.  The Internal Revenue Service is not bound by this
position, and you are encouraged to consult with your tax advisors about the
federal, state and other tax consequences of the program.

                              October ____, 1999



Dear Broker:

As you may know, we are undertaking an initial public offering of our shares of
common stock.  We are permitting Safeguard Scientifics, Inc. to use its Directed
Share Subscription Program to offer Safeguard stockholders the opportunity to
buy shares of our common stock at the initial public offering price.  The price
per share under this program will be the same price that all investors will pay
in our initial public offering.

The enclosed questions and answers will provide you with the key terms of the
Directed Share Subscription Program.

If you have any questions regarding the Directed Share Subscription Program,
please call Safeguard's automated investor relations line at (888) SFE-1200.
Please do not call Pac-West Telecomm regarding this program.  You also may find
information about this program on Safeguard's web site at www.safeguard.com.

Preliminary prospectuses for distribution to Safeguard stockholders are being
distributed through Corporate Investor Communications, Attention:  Processing
Department, 111 Commerce Road, Carlstadt, NJ 07072-2586, telephone number (201)
896-1900.  Please call Corporate Investor Communications if you do not receive a
sufficient number of prospectuses for distribution to Safeguard stockholders.
You should provide a copy of the preliminary prospectus to each Safeguard

                                      Sincerely,


                                      Wallace W. Griffin

                          SAFEGUARD SCIENTIFICS, INC.
                      DIRECTED SHARE SUBSCRIPTION PROGRAM
                          FOR PAC-WEST TELECOMM, INC.

Q:  Who is eligible to participate in the directed share subscription program
    for Pac-West Telecomm, Inc.?
A:  Only record holders of at least 100 shares of Safeguard stock on ______ __,
    1999.

Q:  How was the opportunity to purchase IPO shares allocated to Safeguard
    stockholders?
A:  Safeguard stockholders received a subscription offer to purchase 1 share of
    Pac-West for each 10 shares of Safeguard owned on August 31, 1999, subject
    to the minimum purchase requirement.

    If a Safeguard stockholder owned at least 100 shares of Safeguard common
    stock but the number of shares was not evenly divisible by 10, Safeguard
    will round up the subscription offer to the next whole number.  The
    Depository Trust Company will notify its participants of the date by which
    the roundup requests must be submitted.

    The offer to purchase shares under the directed share subscription program
    is nontransferable and cannot be combined among multiple accounts.

    There will not be an oversubscription privilege under this program.

Q:  Is there a minimum purchase requirement?
A:  The minimum subscription that will be accepted is for 10 shares of Pac-West
    common stock. Therefore, holders of fewer than 100 Safeguard shares as of
    ______ __, 1999 will be unable to purchase shares in the directed share
    subscription program for Pac-West.

Q:  How will I know when the offering prices and what the expiration date for
    the offering will be?
A:  When the offering is declared effective by the SEC and the offering price is
    set, Safeguard will
    .  issue a press release to the wire services
    .  send you an e-mail alert if you signed up for this on its Web page at
       www.safeguard.com
    .  post this information on its Web page
    .  update its automated investor relations line (888) SFE-1200 through which
       you will be able to listen to the text of the press release announcing
       the price and the expiration date or request a faxed copy of the release
    .  notify the New York Stock Exchange and request that they notify all of
       their members
    .  notify the Depository Trust Company, which will electronically notify all
       of its participants
<PAGE>

Q:  When can subscriptions and payment be submitted?
A:  Subscriptions and payment will only be accepted by the offering agent after
    the initial public offering price of the Pac-West common stock has been
    determined. ChaseMellon Shareholder Services, L.L.C. is the offering agent.

    Once a subscription and payment have been received and accepted by the
    offering agent, the subscription may not be revoked.

    The offering agent will stop accepting subscriptions and payments at 5:00
    p.m. New York City time on the fourth business day after the IPO price has
    been set.

    The Depository Trust Company will handle subscriptions on behalf of its
    participants. When you subscribe for shares of Pac-West through DTC's
    automated subscription system, you will be required to confirm that you are
    subscribing only on behalf of holders that meet the minimum per account
    purchase requirement of 10 shares.

Q:  When will the Pac-West shares purchased in the directed share subscription
    program be distributed?
A:  The offering agent is expected to distribute the shares to The Depository
    Trust Company on the second business day following the expiration of the
    directed share subscription program.

Q:  Is there a cost basis attributable to the subscription offer?
A:  We believe that Safeguard shareholders will not be considered to have
    received a taxable distribution of property as a result of having the
    opportunity to participate in the directed share subscription program.
    However, the Internal Revenue Service is not bound by this position. We
    encourage you to consult with your own tax advisor about the federal, state
    and other tax consequences of this program.

                               SUBSCRIPTION FORM




The shareholder named above has the right to purchase, pursuant to the terms and
conditions of the Safeguard Scientifics, Inc. Directed Share Subscription
Program, the number of fully paid and non-assessable shares of common stock,
$0.001 par value, of Pac-West Telecomm, Inc. indicated above at a subscription
price that will be determined as outlined below.  THE DIRECTED SHARE
SUBSCRIPTION PROGRAM WILL EXPIRE AT 5:00 P.M. NEW YORK CITY TIME ON THE FOURTH
BUSINESS DAY AFTER THE INITIAL PUBLIC OFFERING PRICE IS DETERMINED.  As
described in the preliminary prospectus accompanying this Subscription Form,
each holder of at least 100 shares of Safeguard Scientifics, Inc. common stock
may subscribe for one share of Pac-West Telecomm common stock for every 10
shares of Safeguard Scientifics common stock held as of             , 1999, in
any account, rounded upward.  The minimum subscription that we will accept is
for 10 shares of Pac-West Telecomm per any individual account.  Therefore,
holders with accounts containing fewer than 100 shares of Safeguard common stock
as of             , 1999, will not be able to subscribe for shares of Pac-West
Telecomm.  The right to participate in this program and purchase shares of Pac-
West Telecomm is nontransferable except involuntarily by operation of law (e.g.,
death or certain dissolutions).  Should an involuntary transfer occur by
operation of law, please contact ChaseMellon Shareholder Services, L.L.C., the
agent for the program, by telephone at 800-777-3674 for appropriate
instructions.

The subscription price per share under the program will be the same price that
all investors will pay in Pac-West Telecomm's initial public offering.  The
price per share will be determined by negotiations between Pac-West Telecomm and
the underwriters of the offering.  The factors to be considered in these
negotiations are described in the preliminary prospectus accompanying this
Subscription Form.  Pac-West Telecomm currently anticipates that its initial
public offering price will be determined in           ,  1999 but various
factors could hasten or delay this determination. Time will not permit Pac-West
Telecomm to notify you directly of the subscription price and the expiration
date for this offering, but Safeguard Scientifics will take the actions
described in the accompanying preliminary prospectus to publicize this
information.

No offer to buy securities can be accepted, and no part of the subscription
price can be received, until the initial public offering price has been
determined and the registration statement, of which the preliminary prospectus
accompanying this Subscription Form is a part, has been declared effective.  Any
Subscription Forms or payments received before then will be returned to you.
All persons electing to subscribe for shares of Pac-West Telecomm, Inc. must
complete the Election to Purchase on the reverse side of this Subscription Form
and return the Subscription Form, together with full payment of the subscription
price, to ChaseMellon at the addresses on the back of this Subscription Form.
If you do not properly complete and sign this Subscription Form, it may be
rejected.  Once the Subscription Form and payment have been received and
accepted, your subscription may not be revoked by you.  The Subscription Form
and full payment of the subscription price must be received by ChaseMellon no
later than 5:00 p.m. New York City time on the fourth business day after the
initial public offering price is determined.  ChaseMellon will not honor any
subscriptions received after that time and date.  If you do not wish to
subscribe for shares, you do not need to return this Subscription Form.  Before
completing and returning this Subscription Form, you are urged to read carefully
the preliminary prospectus mailed to you with this Subscription Form for a more
complete explanation of the offering and for information about Pac-West
Telecomm.  If Pac-West Telecomm cancels the initial public offering, you will

submitted by you will be returned.  Pac-West Telecomm and/or Safeguard also may
cancel or modify, in whole or in part, the directed share subscription program.
