                               Prospectus Summary

You should read the following summary together with the more detailed
information and financial statements and related notes appearing elsewhere in
this prospectus.

                             Cortelco Systems, Inc.

Cortelco designs, develops and markets integrated enterprise communications
systems for routing and controlling the voice, video and data communications of
businesses and other organizations. Our solutions are primarily designed for
enterprises with complex communications needs and small and medium-sized
telephony installations. We serve a variety of vertical markets such as
education, retail, government agencies, emergency-911 services and catalog
sales, as illustrated by the variety of organizations that have bought our
products: Bell Atlantic, Budget Rent-A-Car, Circuit City, the Federal Aviation
Administration and U-Haul. Our products are installed in over 7,100 locations
worldwide. In addition to selling our products, we also resell cellular
airtime, cellular telephones and third-party voice communications systems in
Puerto Rico. Our products have won numerous awards, including "Best of Show"
awards at CT Expo in 1997 and 1998 and "Product of the Year" awards in 1997 and
1998 from Call Center magazine and in 1999 from Call Center Solutions magazine.


Our communications systems are based on two platforms, the Millennium and the
DSP Series. Both of our platforms support multi-site networking and other
advanced features such as dynamic call routing, interactive voice response,
voicemail and computer telephony integration. The Millennium is a full-function
routing and control system that primarily serves customers averaging
approximately 110 communications ports per installation. The Millennium also
includes automatic call distribution features. The DSP Series is primarily an
advanced automatic call distribution system that also includes a full-function
routing and control system. The DSP Series is typically used in installations
requiring advanced computer telephony integration applications such as those
used in sophisticated call centers. Both the Millennium and the DSP Series
interface with a variety of popular third-party products through standard
protocols.

Our integrated communications systems are flexible enough to meet the needs of
enterprises with small to medium-sized installations, yet are scalable enough
to accommodate these enterprises as they grow. Key elements of our strategy
include:

    . targeting enterprises with small to medium-sized installations at one
      or more locations

    . providing customers with cost-effective, integrated solutions for
      their voice communications requirements

    . expanding both our direct sales force and our dealer network to more
      aggressively pursue our target markets

    . continuing to enhance our core product lines and develop new features
      and applications that leverage our existing Millennium and DSP Series
      platforms

As a result of these initiatives and a contract with the FAA accounting for
$9.7 million of revenue during the nine months ended April 30, 1999, our
revenues on a pro-forma basis increased 48.3% from $26.2 million for the nine
months ended April 30, 1998 to $38.9 million for the nine months ended April
30, 1999. Current development efforts address emerging market needs, such as
unified messaging, voice-over-Internet Protocol ("voice-over-IP") and Web-based
virtual call center capabilities.

We are a Delaware corporation with executive offices located at 4119 Willow
Lake Blvd., Memphis, Tennessee 38118 and our telephone number is (901) 365-

                                  Risk Factors

This offering involves a high degree of risk. You should carefully consider the
risks and uncertainties described below and the other information in this
prospectus before deciding whether to invest in shares of our common stock.

Fluctuations in Our Quarterly Operating Results Could Adversely Affect the
Price of Our Common Stock

Our operating results are likely to fluctuate significantly from quarter to
quarter in the future due to a number of factors, many of which are beyond our
control. As a result, our operating results will likely not meet expectations
in some future quarters, which could have a material adverse effect on the
market price of our common stock. Factors that could affect our quarterly
operating results include the following:

    . variations in the mix of products sold

    . variations in the timing or size of orders from our customers

    . completion of significant contracts such as the FAA contract

    . delays or difficulties in introducing new products and/or in
      implementing common applications across both our Millennium and DSP
      Series platforms

    . price decreases and other actions by our competitors

Quarterly operating results are also likely to fluctuate due to seasonal
factors that affect customers in some of our vertical markets. For example,
U.S. government customers typically make substantial purchases during the
quarter ended October 31, the last quarter of the government's fiscal year, and
these purchases decline significantly in the next quarter. Customers in other
vertical markets such as education and retail have also exhibited seasonal
buying patterns and do not purchase substantial amounts of equipment during the
quarter ended January 31. As a result, revenues in the quarter ended January 31
are often lower than in the previous quarter.

The uncertainty of our sales cycle also makes the timing of sales difficult to
predict and may cause fluctuations in our quarterly operating results. The
purchase of our products may involve a significant commitment of our customers'
personnel, financial and other resources to conduct technical evaluations, to
support installation and training and to fund purchases. As a result, our sales
cycles vary from one to six months for Millennium systems, which range in price
from $22,000 to $36,000 depending on the system configuration, and from four to
twelve months for DSP Series systems, which range in price from $75,000 to
$230,000 depending on the system configuration. Additionally, our reliance on
dealers and value added resellers to market our products makes it even more
difficult to predict the timing of sales because we have little control over
their selling efforts to end-user customers.

We generally recognize revenues on the date of shipment for Millennium systems,
but upon acceptance for DSP Series systems due to the customized nature of the
installation. Delays in shipment or acceptance due to late deliveries by our
contract manufacturers and other factors beyond our control could adversely
affect revenues in a quarter.

Our Recent Results Have Been Affected by Our Contract with the FAA

Our recent revenues have been significantly influenced by one large customer,
the FAA. In June 1998, we began installing DSP Series systems in approximately
61 FAA sites. The FAA contract accounted for $9.7 million in revenues, or 25.0%
of our pro forma revenues, for the nine months ended April 30, 1999. The FAA
contract is expected to be completed in June 1999. We cannot guarantee that we
will be able to obtain sufficient additional customer contracts to avoid a
decline in revenues after the FAA

                                       4
<PAGE>


contract is completed. Because of the significant contribution of the FAA
contract to our revenues during the nine months ended April 30, 1999, we expect
that our revenue growth in the next quarter will be less than the 48% growth
seen over the last nine months ended April 30, 1999.

We Have a Limited Combined Operating History with BCS and Cortelco Systems
Puerto Rico

We have a limited combined operating history because we only recently acquired
BCS and merged with Cortelco Systems Puerto Rico. As a result, unanticipated
difficulties or delays may arise during the process of integrating our product
lines, our product development and sales and marketing efforts. Our operating
results may be adversely affected if we are not able to realize anticipated
operating efficiencies through the consolidation of certain administrative and
corporate functions and if we are not able to effectively integrate our
corporate cultures. See "Company Background."

We Have Many Established Competitors in the Communications Equipment Market

The market for our products is highly competitive and subject to rapid
technological change. We expect competition to increase significantly in the
future. Our principal competitors in the voice communications equipment market
include Lucent Technologies, Mitel, NEC, Nortel Networks and Siemens. We also
compete with Aspect Telecommunications and Rockwell Electronic Commerce in the
call center market. As voice and data communications networks converge, data
equipment vendors such as Cisco Systems and 3Com may also compete in our
market. In addition, alliances and mergers between telecommunications and
computer companies may strengthen our competitors' positions or result in new
entrants into our market.

Many of our current and potential competitors have significantly greater
financial, technical, marketing, customer services and other resources, greater
name recognition and a larger installed customer base than we do. As a result,
our competitors may be able to respond to new or emerging technologies and
changes faster than we can. They may also be able to devote greater resources
to the development, promotion and sale of their products. Actions by our
competitors could result in price reductions, reduced margins and loss of
market share, any of which would have a material adverse effect on our
financial condition. We cannot assure you that we can compete successfully
against our competitors or that competitive pressures would not have a material
adverse effect on our operating results and financial condition.

We Have a Limited Direct Sales Force and Rely on Dealers and Value Added
Resellers

We have a limited direct sales force and rely on our dealers and value added
resellers to market our products. Authorized dealers and value added resellers
accounted for approximately 30% of our pro forma revenues in fiscal 1998.
Generally, our authorized dealers and value added resellers have no obligation
to sell our products and in many cases also offer our competitors' products.
Our authorized dealers and value added resellers could discontinue selling our
products at any time in favor of our competitors' products or for any other
reason. A reduction or loss of orders from our dealers and value added
resellers could have a material adverse effect on our operating results and
financial condition.

We Need to Increase Our Sales Capability

In order to increase sales, both domestically and internationally, we will need
to add to our direct sales force, expand existing distribution channels and
establish new distribution channels for our products. A failure to increase
existing or establish new distribution channels or hire personnel necessary to
develop and enhance such distribution channels could have a material adverse
effect on our operating results and financial condition. We have increased our
sales force by approximately 48% since April 30, 1998. We cannot assure you
that new sales personnel, dealers and value added

                                       5
<PAGE>

resellers will be effective at increasing sales or will achieve the same levels
of productivity as our existing sales resources. In addition, as we expand our
distribution channels, our direct sales force, dealers and value added
resellers may compete with each other for the same customers.

Our Product Platforms Must Integrate with Changing Protocols, Applications and
Third Party Technology to Remain Competitive

The markets for our products are characterized by rapid technological change,
evolving industry standards, changes in end-user customer requirements and
frequent new product introductions and enhancements. Our future success will
depend upon our ability to enhance our existing products and to develop and
introduce new products that will achieve market acceptance. A key feature of
our product platforms is their ability to integrate with most standard
protocols and transmission systems, computer telephony integration and
automatic call distribution applications and protocols, operating systems and
databases. In the event that our product platforms cannot be readily integrated
with third-party technology or newly developed technological advances which we
may fail to predict, we could be required to redesign our core product
platforms. In addition, the introduction or market acceptance of products
incorporating superior technologies or the emergence of alternative
technologies and new industry standards could also render our existing
products, as well as products currently under development, obsolete and
unmarketable. Redesigning any of our products may require significant
resources, and any failure to release new products or to enhance or redesign
our existing products in a timely manner could have a material adverse effect
on our operating results and financial condition.

We Depend on a Single Source of Supply for Some Electronic Components

Our products are manufactured using components or subassemblies procured from
third-party suppliers. We receive some electronic components from a single
source. For example, we rely on Siemens to provide the digital signal
processors and associated chip sets for our Millennium and DSP Series products.
We rely on Natural Microsystems to supply the voice processors for our Cortelco
Voice Processing System and on CTP Systems to supply our Orbit Wireless
Communications handsets and base stations. Any interruption in the availability
of components from our key suppliers could adversely affect our ability to meet
our scheduled product deliveries. We also could experience difficulties in
identifying alternative sources or modifying product designs to use alternative
components. Resulting delays or reductions in product shipments could damage
customer relationships and adversely affect our operating results. Further, a
significant increase in the price of one or more third-party components or
subassemblies would have a material adverse effect on our gross profit and
operating results.

We Depend on Third-Party Contract Electronic Manufacturers

We depend heavily upon the manufacturing capabilities of CMC Industries, Inc.
and Pensar Corporation, our primary contract electronic manufacturers. Our
ability to deliver products on a timely basis could be adversely affected by
any failure of CMC or Pensar to manufacture our products. In addition, we could
have difficulty finding other manufacturers to build our products. Resulting
delays in manufacturing or shipping or an inability to meet customer orders
could adversely affect our customer relationships and our operating results.

We Depend on Management and Key Engineering Personnel and Need to Attract
Qualified New Employees

We are dependent on the principal members of our management team and key
members of our engineering staff. If we lose any of these persons, our
business, financial condition and operating results may be adversely affected.
Due to the specialized nature of our business, we are highly dependent on the
continued service of, and on the ability to attract and retain, qualified
engineering, sales, marketing

                                       6
<PAGE>

and senior management personnel. Highly skilled employees with the education
and training that we require, especially qualified service technicians and
employees with significant experience and expertise in computer telephony
integration applications, are in high demand. If we are unable to hire
additional qualified personnel as needed, we may not be able to grow our
business effectively, adequately manage and complete our existing sales
commitments or bid for and execute additional sales opportunities. Failure to
attract and retain the qualified personnel necessary for the development of our
business could have a material adverse effect on our operating results and
financial condition.

We Face Many Risks in Expanding Our International Operations into the Caribbean
and Latin America

Sales outside of the United States and Puerto Rico accounted for approximately
2% of our total pro forma revenues for the nine months ended April 30, 1999 and
were made primarily through our dealer network. We expect to increase sales to
customers outside of the United States as we establish our distribution
channels in the Caribbean and Latin America. However, foreign markets for our
products may develop more slowly than currently anticipated. We may not be able
to successfully establish international distribution channels, or we may not be
able to hire the additional personnel necessary to support such distribution
channels. In addition, payment cycles with customers located outside the United
States are generally longer than those within the United States.

Our Products May Have Undetected Errors Leading to Product Returns or Claims of
Liability

Our products, despite testing, may contain undetected errors or failures. The
occurrence of errors could result in product returns and other losses to us or
our customers. This occurrence also could result in the loss of, or delay in,
market acceptance of our products. In addition, any failure by our products to
properly perform could result in claims against us. Our purchase agreements
with our customers typically contain provisions designed to limit our exposure
to potential product liability claims. However, the limitation of liability
provisions contained in our purchase agreements may not be effective as a
result of federal, state or local laws or ordinances or unfavorable judicial
decisions in the United States or other countries. We maintain insurance to
protect against certain claims associated with the use of our products, but our
insurance coverage may not adequately cover all possible claims asserted
against us. In addition, even claims that ultimately are unsuccessful could
result in our expenditure of funds in litigation and management time and
resources.

We May Be Subject to Intellectual Property Litigation

As we grow and gain brand recognition, our products are more likely to be
subjected to infringement litigation. Responding to, defending against, or
bringing claims related to our intellectual property rights could result in
substantial costs and diversion of management and technical resources which
could adversely affect our business, operating results and financial condition.
In addition, we rely on a combination of patent, trademark, copyright and trade
secret laws and contractual restrictions to establish and protect our
proprietary rights. These statutory and contractual arrangements may not
provide sufficient protection to prevent misappropriation of our technology or
to deter independent third-party development of similar technologies. Such
litigation could result in our expenditure of funds and management time and
resources.

We May Be Affected by Year 2000 Problems in Our Systems or Those of Our Key
Suppliers, Manufacturers or Customers

We are heavily dependent upon the ability of our own computer or data-dependent
systems to correctly interpret century data. This includes, but is not limited
to, our systems in information,

                                       7
<PAGE>

business, finance, operations and service. Any failure or malfunctioning on the
part of these or other systems could adversely affect us in ways that are not
currently known, discernible, quantifiable or otherwise anticipated by us. We
currently have only limited information on the Year 2000 compliance of our key
suppliers, manufacturers and customers. Our business and operating results
could experience material adverse effects if our key suppliers or manufacturers
were to experience Year 2000 issues that cause them to delay production or
shipment of key components or systems. In addition, our operating results could
experience material adverse effects if any of our key customers encounter Year
2000 issues that cause them to delay or cancel substantial purchase orders or
delivery of our product. For a discussion of our Year 2000 plans, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Compliance."

We Are Controlled by Our Principal Stockholders and Management

Upon completion of this offering, our executive officers, directors and
principal stockholders and their affiliates will own approximately 5,405,369
shares, or 47.5%, of the outstanding shares of common stock, or     shares, or
  %, if the underwriters' over-allotment option is exercised in full. As a
result, they will have the ability to effectively control us and direct our
affairs, including the election of directors and approval of significant
corporate transactions. This concentration of ownership also may have the
effect of delaying, deferring or preventing a change in control of our company
and may make some transactions more difficult or impossible without the support
of these stockholders. The interests of these stockholders may conflict with
those of other stockholders. We also have transactions with businesses in which
our principal stockholders maintain interests, such as CMC. We believe that
these transactions are conducted at an arm's length basis, but we cannot assure
you that these transactions would have the same terms if conducted with an
unrelated third-party.

Our Stock Previously Had No Active Public Market and Our Stock Price May Be
Volatile

Prior to this offering, there has been no public market for our common stock.
We have applied to list the common stock for trading on the Nasdaq National
Market. The initial public offering price will be determined by negotiations
among the underwriters, us and the selling stockholders and may not be
indicative of the market price for the common stock after this offering. We do
not know the extent to which investor interest will lead to the development of
a public market. Investors may not be able to resell the common stock at or
above the initial public offering price. Many factors could cause the market
price of the common stock after this offering to fluctuate substantially,
including future announcements concerning us or our competitors, variations in
operating results, loss of key customers, changes in pricing policies, or
changes in earnings estimates by analysts. General economic, political and
market conditions may also have a material adverse effect on the price of our
common stock.

Some Anti-Takeover Provisions May Adversely Affect Our Stock Price

The board of directors has the authority to issue up to 10,000,000 shares of
preferred stock and to determine the preferences, rights and privileges of
those shares without any further vote or action by the stockholders. The rights
of the holders of common stock may be adversely affected by the rights of the
holders of any preferred stock that may be issued in the future. Certain
provisions of our certificate of incorporation and bylaws may make it more
difficult for a third-party to acquire control of us without the consent of our
board of directors, even if such changes were favored by a majority of the
stockholders. These include provisions that provide for a staggered board of
directors, prohibit stockholders from taking action by written consent and
restrict the ability of stockholders to call special meetings.

                                       8
<PAGE>

Significant Number of Shares Eligible for Future Sale May Decrease Our Stock
Price

Sales of substantial amounts of our common stock in the public market after
this offering, including shares issued upon the exercise of outstanding
options, or the perception that such sales could occur, could adversely affect
the market price of our common stock. These sales also might make it more
difficult for us to raise funds through future offerings of common stock.

Upon completion of this offering, we will have outstanding 11,374,826 shares of
common stock. All of the shares sold in this offering will be freely
transferable without restriction or further registration under the Securities
Act of 1933, except for shares purchased by our "affiliates," as defined in
Rule 144 under the Securities Act. The remaining 8,254,826 shares of common
stock that will be outstanding upon completion of this offering are "restricted
securities" as defined in Rule 144. These restricted securities may be sold in
the future without registration under the Securities Act to the extent
permitted under Rule 144, Rule 701, or another exemption under the Securities
Act. Cortelco, our officers, directors and stockholders holding approximately
7,277,419 shares of common stock will agree not to, without the prior written
consent of J.P. Morgan Securities Inc., directly or indirectly, sell, offer,
contract to sell, transfer the economic risk of ownership in, make any short
sale, pledge or otherwise dispose of any shares of common stock or any
securities convertible into, or exchangeable, or exercisable for, or any other
rights to purchase or acquire shares of common stock owned by them during the
180-day period commencing on the date of this prospectus.

                           Forward-Looking Statements

Statements contained in this prospectus may be forward-looking statements
concerning our operations, economic performance and financial condition.
Forward-looking statements are included, for example, in the discussions about:
the timing and availability of products under development; variations in
operating results; our strategy; Year 2000 issues; and the market for voice
communications equipment. Those forward-looking statements involve risks and
uncertainties and actual results may differ materially from those expressed or
implied in those statements. Factors that could cause differences include, but
are not limited to, those discussed under "Risk Factors" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                               Company Background

We were incorporated on July 23, 1991 as one of several corporations related
through common ownership that were formed to hold various telecommunications
equipment and other businesses that had been acquired primarily from Alcatel,
N.V. in 1990. In August 1993, we became a subsidiary of Cortelco Systems
Holding Corporation, a corporation formed to act as the holding company for the
telecommunications equipment businesses, while CMC Industries, Inc., a contract
electronic manufacturer, became a separate company. See "Business--
Manufacturing." In March 1997, our subsidiary in the automatic call
distribution products business was spun off to the Cortelco Systems Holding
Corporation stockholders, merged with Business Communications Systems, Inc.,
and renamed "BCS Technologies, Inc."

In April 1999:

    . Cortelco Systems Holding Corporation distributed its shares of
      Cortelco common stock in a spin-off transaction

    . we merged with Cortelco Systems Puerto Rico, Inc., another subsidiary
      of Cortelco Systems Holding Corporation, in exchange for 553,880
      shares of our common stock

    . we acquired BCS in exchange for 3,969,681 shares of our common stock

BCS and Cortelco Systems Puerto Rico are now wholly-owned subsidiaries of
Cortelco.

                                Use of Proceeds

Our net proceeds from the sale of the 2,300,000 shares of common stock offered
by us are estimated to be approximately $23.0 million or approximately $23.4
million if the underwriters exercise the over-allotment option in full, after
deducting underwriting discounts and commissions and estimated offering
expenses payable by us. We will not receive any proceeds from the sale of
common stock by the selling stockholders.

We currently intend to use our net proceeds from this offering:

    . to fully repay a $2.3 million long-term subordinated note with
      ChinaVest IV, L.P. that accrues interest at an 8.0% annual rate and
      matures in July 2002

    . to fully repay $2.6 million of senior debt under two credit facilities
      with Foothill Capital, one of which accrues interest at a rate equal
      to the prime rate plus 0.375% and matures in July 2001, and the other
      of which accrues interest at a rate equal to the prime rate plus 1.25%
      and matures in August 2001

    . for working capital and general corporate purposes

We may also use some of the proceeds to acquire other companies, technologies
or products that complement our business, although we have not yet developed
any plans regarding these transactions. Pending use of the net proceeds as
described above, we intend to invest the net proceeds from this offering in
short-term, investment-grade securities.

                                Dividend Policy

We have declared cash dividends in the past in connection with intercompany
financing transactions with our parent company. See "Certain Transactions."
Cortelco currently anticipates that it will retain earnings to support
operations and finance the growth and development of its business and does not
anticipate declaring cash dividends for the foreseeable future. Future
dividends, if any, will be at the discretion of the board of directors, which
will base its decision on a number of factors, including our operating results
and financial requirements. The terms of our senior debt, which will be repaid
from the net proceeds of this offering, prohibit the declaration and payment of
dividends without the approval of the lender.

                                 Capitalization

The following table sets forth our capitalization as of April 30, 1999 on an
actual basis and on an adjusted basis after giving effect to the sale of
2,300,000 shares of common stock in this offering and net proceeds after
deducting underwriting discounts and commissions and estimated offering
expenses payable by us. The capitalization on an actual basis excludes

                                    Dilution

Our net tangible book value at April 30, 1999 was approximately $4.4 million,
or $0.57 per share of common stock. Net tangible book value per share
represents the amount of total assets, less:

  . goodwill and identifiable intangible assets

  . total liabilities

  . preferred stock

divided by the number of outstanding shares of common stock.

After giving effect to the sale of 2,300,000 shares of common stock offered to
new investors by Cortelco at an assumed initial public offering price of $11.00
per share, and after deducting underwriting discounts and commissions and
estimated offering expenses, our pro forma net tangible book value at April 30,
1999 would have been approximately $27.7 million, or $2.43 per share. This
represents an immediate increase in pro forma net tangible book value of $1.86
per share to existing stockholders and an immediate dilution in net tangible
book value of $8.57 per share to new investors. The following table illustrates
the per share dilution:

                 Selected Pro Forma Consolidated Financial Data

The following pro forma consolidated statement of operations data for the year
ended July 31, 1998 and the nine months ended April 30, 1998 and 1999 represent
the unaudited pro forma operating results as if the acquisition of BCS had
occurred as of August 1, 1997. The pro forma financial data reflects
adjustments to our consolidated financial statements that:

  . reflect the purchase method of accounting for the acquisition of BCS

  . eliminate the results of operations and related assets and liabilities
    not acquired from the merger with Cortelco Systems Puerto Rico

The pro forma financial data does not purport to represent what our results of
operations actually would have been had the transactions occurred on the dates
indicated, or to project our results of operations at any future date or for
any future period. The following pro forma financial data should be read in
conjunction with Cortelco's consolidated financial statements and related
notes, BCS' consolidated financial statements and related notes and the
Unaudited Pro Forma Consolidated Financial Information and related notes, all
of which are included elsewhere in this prospectus, and "Management's

                    Management's Discussion and Analysis of
                 Financial Condition and Results of Operations

The following discussion of our results of operations and financial condition
should be read in conjunction with the consolidated financial statements and
related notes and other financial information included elsewhere in this
prospectus. This discussion contains forward-looking statements that involve
risks and uncertainties. Our actual results may be materially different from
those anticipated in these forward-looking statements as a result of certain
factors, including, but not limited to, those set forth under "Risk Factors"
and elsewhere in this prospectus.

Overview

Cortelco designs, develops and markets integrated enterprise communications
systems for small and medium-sized telephony installations in a range of
vertical markets such as education, retail, government agencies, emergency-911
services and catalog sales. Our operations are conducted through three business
units: Systems Business Operations, ACD Business Operations and Caribbean and
Latin American Operations. The Systems Business Operations unit primarily
focuses on the Millennium product line. The ACD Business Operations unit
primarily focuses on the DSP Series product line. The Caribbean and Latin
American Operations unit currently distributes the Millennium and DSP Series
systems and resells cellular airtime, cellular telephones and third-party voice
communications systems in Puerto Rico.

In April 1999, Cortelco merged with its sister company, Cortelco Systems Puerto
Rico, which became the Caribbean and Latin American Operations unit, and
acquired BCS, which became the ACD Business Operations unit. Prior to April
1999, our three business units shared substantial common ownership and prior to
March 1997 had been part of the same corporate family. Cortelco and Cortelco
Systems Puerto Rico had previously been subsidiaries of Cortelco Systems
Holding Corporation and were under common control. As a result, the merger of
Cortelco and Cortelco Systems Puerto Rico has been recorded for all periods
presented at historical costs and the financial statements are presented on a
consolidated basis for all historical periods. The acquisition of BCS has been
accounted for using the purchase method of accounting and goodwill in the
amount of $11.3 million was recorded in the BCS acquisition and is being
amortized over 20 years. BCS has been included in our consolidated financial
statements from April 12, 1999, the date on which it was acquired.

Our revenues are primarily derived from our sale of Millennium and DSP Series
systems, related systems products and services and the resale of cellular
airtime, cellular telephones and third-party voice communications systems in
Puerto Rico. Revenue is recognized upon shipment of product to our dealers and
end-user customers for Millennium systems and third-party systems, and upon
acceptance for DSP Series systems due to the customized nature of each
installation. In addition, our Caribbean and Latin American Operations unit
generates revenue from the resale of cellular airtime and cellular telephones
in Puerto Rico and recognizes these revenues when earned. Typical selling
prices range from $22,000 to $36,000 for Millennium systems and $75,000 to
$230,000 for DSP Series systems, depending on the system configuration. For the
nine months ended April 30, 1999, on a pro forma basis, we generated
approximately 43% of our revenue from the sale of Millennium products and
approximately 34% from the sale of DSP Series products. Pro forma revenues
increased 48.3% from $26.2 million for the nine months ended April 30, 1998 to
$38.9 million for the nine months ended April 30, 1999.

In the past several years, we have undergone some significant changes. In
fiscal 1994, we introduced a new digital platform, the Millennium, to replace
an older analog product, which was ultimately discontinued in fiscal 1998.
During fiscal 1996 and fiscal 1997, we sold a substantial number of

                                       16
<PAGE>


Millennium systems to a single customer for installations in Southeast Asia.
This customer ceased placing new orders with us in 1997 due to general economic
instability in Southeast Asia, which resulted in a $2.9 million decrease in
purchases by this customer in fiscal 1998 as compared to fiscal 1997. Moreover,
in fiscal 1997, Cortelco Systems Puerto Rico redirected its marketing of
cellular airtime and cellular telephones to focus on higher quality customers,
mainly businesses, in order to minimize credit losses and increase margins.
This resulted in a reduction of Cortelco Systems Puerto Rico's revenues from
the resale of cellular airtime and cellular telephones from $9.8 million in
fiscal 1997 to $6.7 million in fiscal 1998. Beginning in the second quarter of
fiscal 1998, Cortelco, under the leadership of a new president, refocused its
overall marketing strategy and began to target markets for which the Millennium
system is particularly well-suited. Product development programs have been
directed to new software and other initiatives to strengthen the Millennium
product line and increase gross margins. We also increased our sales staff and
expanded our dealer and value added reseller network. As a result of these
changes and programs, Cortelco has become profitable and our operating results
have continued to improve in recent quarters.

Pro Forma Results of Operations

As a result of the recent acquisition of BCS, our historical financial
statements for past periods do not accurately reflect our current results of
operations. We have therefore included the results of operations on a pro forma
basis for each of the seven quarters ended April 30, 1999 so that you can
better understand our business. The following tables present the pro forma
results as if the acquisition of BCS had occurred as of August 1, 1997. We
believe that all necessary adjustments, consisting of only normal recurring
adjustments, have been included in the amounts stated below. The pro forma
financial data are presented for illustrative purposes only and do not purport
to represent what our results of operations actually would have been had the
transactions occurred on the dates indicated, or to project our results of
operations for any future period. This data should be read in conjunction with
the Unaudited Pro Forma Consolidated Financial Information and the related
notes, our consolidated financial statements and the related notes and BCS'
financial statements and the related notes, all of which are included elsewhere
in this prospectus.

Quarterly results of operations, in particular the quarters ended October 31
and January 31, are likely to fluctuate due to a number of factors, including
seasonal factors that affect customers in some of our vertical markets. For
example, U.S. government customers typically make substantial purchases during
the quarter ended October 31, the last quarter of the government's fiscal year,
and these purchases decline significantly in the next quarter. Customers in
other vertical markets such as education and retail have also exhibited
seasonal buying patterns and do not purchase substantial amounts of equipment
during the quarter ended January 31. As a result, revenues in the quarter ended
January 31 are often lower than in the previous quarter. The uncertainty of our
sales cycle also makes the timing of sales difficult to predict and may cause
fluctuations in our quarterly results of operations. The purchase of our
products may involve a significant commitment of our customers' personnel,
financial and other resources to conduct technical evaluations, to support
installation and training and to fund purchases. As a result, our sales cycles
vary from one to six months for Millennium systems and from four to twelve
months for the DSP Series systems.

                                       18

Revenues. Our revenues are primarily derived from the sales of Millennium and
DSP Series systems, related systems products and services and the resale of
cellular airtime, cellular telephones and third-party voice communications
systems in Puerto Rico. Our pro forma quarterly revenues have increased over
the prior year for the last three quarters ended April 30, 1999, due primarily
to the FAA contract, enhancements of our product line and expansion of our
sales force. Systems revenue from sales of third-party voice communications
systems in Puerto Rico generally account for approximately 5% to 10% of pro
forma total revenues in each quarter. Our pro forma cellular airtime and
cellular telephone revenues have generally decreased as a percentage of total
revenues since the quarter ended October 31, 1997, primarily due to our
limiting sales activities to higher quality customers, and were 8.7% of pro
forma revenues for the quarter ended April 30, 1999. Our pro forma revenues for
the quarters ended January 31, 1998 and 1999 have been influenced by seasonal
buying patterns in some of our vertical markets. Consequently, pro forma
revenues are lower in the quarters ended January 31 than in the quarters ended
October 31. Furthermore, our revenues were adversely affected in the first half
of fiscal 1998 due to a decrease in orders from our single largest customer due
to general economic instability in Southeast Asia and the unexpected loss of a
key sales executive. Pro forma revenues reflect purchases by the FAA of
$2.6 million, $2.6 million and $4.5 million for the last three quarters ended
April 30, 1999 under a contract scheduled to expire in June 1999. Although
revenues from the U.S. government will decline after June 1999 due to the
completion of installations under the FAA contract, we expect U.S. government
agencies to continue to account for a significant portion of our systems
revenue.

Pro forma revenues increased 48.3% from $26.2 million for the nine months ended
April 30, 1998 to $38.9 million for the nine months ended April 30, 1999. The
increase was primarily due to $9.7 million in purchases of DSP Series systems
by the FAA and an increase in Millennium revenues of $3.2 million, partially
offset by a decrease in cellular revenues of $0.9 million. Millennium systems
sales increased primarily due to the expansion of our sales force and the
introduction of new product features during the last year, while cellular
revenues decreased during the period due primarily to our decision to target
higher quality customers. For the nine months ended April 30, 1999, the FAA
accounted for 25.0% of our total pro forma revenues. As a result of the
completion of the FAA contract, we expect our revenue growth will slow during
the quarter ended July 31, 1999.

Cost of Revenues and Gross Profit. Cost of revenues consists primarily of
purchases from our contract manufacturers and other suppliers. Pro forma gross
profit increased in year over year comparative quarters due primarily to higher
revenues and a change in product mix in favor of higher margin products,
primarily DSP Series systems. Lower pro forma gross profit in the quarters
ended January 31, 1998 and 1999 were due primarily to seasonal declines in
revenues caused by our customers' purchasing cycles.

Pro forma gross profit increased 69.2% from $11.6 million for the nine months
ended April 30, 1998 to $19.7 million for the nine months ended April 30, 1999.
The increase was primarily due to an increase in DSP Series gross profit from
$2.3 million for the nine months ended April 30, 1998 to $8.9 million for the
nine months ended April 30, 1999. Millennium systems gross profit increased
from $6.0 million for the nine months ended April 30, 1998 to $8.5 million for
the nine months ended April 30, 1999 due primarily to higher revenues. Gross
profit from the resale of cellular airtime and cellular telephones decreased
from $1.2 million for the nine months ended April 30, 1998 to $1.1 million for
the nine months ended April 30, 1999 due primarily to lower cellular revenues.
Pro forma gross margin increased from 44.4% for the nine months ended April 30,
1998 to 50.7% for the nine months ended April 30, 1999 due primarily to the
increase in DSP Series revenues and an increase in gross margin for the DSP
Series from 63.2% of DSP Series revenues for the nine months

                                       19
<PAGE>


ended April 30, 1998 to 66.6% of DSP Series revenues for the nine months ended
April 30, 1999. We expect our gross margins to decline in the quarter ended
July 31, 1999 as our DSP Series revenues decrease due to the completion of the
FAA contract.

Historical Results of Operations of Cortelco and Cortelco Systems Puerto Rico

Cortelco Systems Puerto Rico was merged with Cortelco in April 1999 and has
been recorded for all periods presented at historical costs and the financial
statements are presented on a consolidated basis for all historical periods. We
acquired BCS on April 12, 1999 in a merger accounted for using the purchase
method of accounting. As a result, the historical results of operations for the
nine months ended April 30, 1998 and the fiscal years ended July 31, 1996, 1997
and 1998 represent the results of Cortelco Systems Puerto Rico and Cortelco and
include the operating results of BCS beginning on April 12, 1999.

Nine Months Ended April 30, 1998 and 1999

Revenues. Total revenues increased 21.1% from $22.8 million for the nine months
ended April 30, 1998 to $27.6 million for the nine months ended April 30, 1999.
The increase resulted primarily from increased systems sales in Puerto Rico of
$2.7 million, increased systems sales to the U.S. government of $1.6 million,
DSP Series revenues of $1.1 million subsequent to the April 12, 1999 merger
with BCS and increased sales of Cortelco Voice Processing Systems of
$0.8 million. These increases were partially offset by decreases in cellular
airtime and cellular telephone revenues in Puerto Rico of $0.9 million in an
effort to target higher quality customers.

Cost of Revenues and Gross Profit. Gross profit increased 26.2% from $9.3
million for the nine months ended April 30, 1998 to $11.8 million for the nine
months ended April 30, 1999. The increase in gross profit was due primarily to
$0.9 million in DSP Series gross profit in the current period, increased gross
profit for systems sales in Puerto Rico of $0.8 million, increased gross profit
for systems sales to the U.S. government of $0.6 million and increased gross
profit for the Cortelco Voice Processing Systems of $0.3 million. The gross
margin was 40.9% for the nine months ended April 30, 1998 and 42.7% for the
nine months ended April 30, 1999.

Operating Expenses. Operating expenses increased 17.2% from $8.8 million for
the nine months ended April 30, 1998 to $10.3 million for the nine months ended
April 30, 1999. The increase was due primarily to the hiring of additional
engineering and sales personnel during the period. Results for the nine months
ended April 30, 1999 include $0.5 million in operating expenses for the ACD
Business Operations Division that was established at the time of the merger
with BCS. Operating expenses decreased as a percentage of revenues from 38.6%
for the nine months ended April 30, 1998 to 37.3% for the nine months ended
April 30, 1999.

Selling, General and Administrative. Selling, general and administrative
expenses consist primarily of salaries and benefit costs, advertising and trade
show related costs, and facilities and other overhead expenses incurred to
support the growth of our business. Costs incurred for final assembly, quality
assurance and installation of our systems are included as selling, general and
administrative expenses instead of cost of revenues. Selling, general and
administrative expenses increased from $7.8 million for the nine months ended
April 30, 1998 to $8.8 million for the nine months ended April 30, 1999. The
increased expense was due primarily to the growth of the business and the
hiring of additional sales personnel. These expenses as a percentage of
revenues decreased from 34.0% for the nine months ended April 30, 1998 to 31.8%
for the nine months ended April 30, 1999. We expect selling, general and
administrative expenses to increase as we invest in new sales and service
personnel; however, we anticipate that these expenses will decrease as a
percentage of revenues in future periods.

                                       20
<PAGE>


Research and Development. Research and development expenses consist primarily
of personnel and related expenses for our engineering staff and depreciation of
related equipment. Research and development expenses have generally increased
since the quarter ended October 31, 1997 due primarily to the hiring of
additional engineering personnel. Research and development expenses increased
from $1.0 million for the nine months ended April 30, 1998 to $1.5 million for
the nine months ended April 30, 1999. The increased expenses were due primarily
to the hiring of additional engineering personnel as well as additional
equipment purchases. These expenses as a percentage of revenues increased from
4.6% for the nine months ended April 30, 1998 to 5.4% for the nine months ended
April 30, 1999. We expect research and development expenses to continue to
increase in dollars and as a percentage of revenues in future periods as we
hire additional engineers to support our new product initiatives.

Amortization of Goodwill. Cortelco recorded $11.3 million of goodwill related
to the acquisition of BCS in April 1999 and began amortizing the amount over a
20-year period on April 12, 1999.

Management Fee Expense, Net. Management fee expense consists primarily of net
administrative expenses incurred by or provided to our former parent company
related to administrative services.

Minority Interest. Minority interest represents the minority stockholder's 45%
share of income in Longhai Telecommunications Equipment Co., Ltd. in China.
Cortelco acquired a 55% interest in Longhai in August 1997. Cortelco does not
currently anticipate investing in additional joint ventures in China. See note
9 to our consolidated financial statements.

Income from Operations. Income from operations increased 172.3% from $0.5
million for the nine months ended April 30, 1998 to $1.5 million for the nine
months ended April 30, 1999. This was due primarily to a $2.7 million increase
in systems sales in Puerto Rico and $1.1 million of DSP revenues subsequent to
the merger with BCS on April 12, 1999. Gross profit increased primarily due to
the higher revenues of $4.9 million in the period and the mix of higher margin
products, including the DSP Series. While operating expenses on an absolute
basis for the nine months ended April 30, 1999 increased due primarily to the
hiring of additional sales and engineering personnel, operating growth was
slower than growth in revenues and gross profit for the period.

Years Ended July 31, 1996, 1997 and 1998

Revenues. Revenues were $38.5 million for fiscal 1996, $35.6 million for fiscal
1997 and $30.9 million for fiscal 1998. The decrease from fiscal 1996 to fiscal
1997 resulted primarily from a decrease of $2.0 million in revenues as we
phased out our older analog product and decreases of $0.4 million in cellular
airtime and cellular telephone revenues in Puerto Rico. The decrease from
fiscal 1997 to fiscal 1998 was due primarily to a $3.1 million decrease in
cellular airtime and cellular telephone revenues resulting from our decision to
target higher quality customers and a $2.9 million decrease in orders from our
single largest customer due to general economic instability in Southeast Asia.

Cost of Revenues and Gross Profit. Gross profit was $11.8 million for fiscal
1996, $11.5 million for fiscal 1997 and $12.4 million for fiscal 1998. The
decrease in gross profit from fiscal 1996 to fiscal 1997 was due primarily to
the decrease in revenues. The increase in gross profit from fiscal 1997 to
fiscal 1998 was due primarily to the increased sale of higher margin Millennium
products such as the Cortelco Voice Processing System. Gross margin was 30.6%
for fiscal 1996, 32.2% for fiscal 1997 and 40.2% for fiscal 1998.

Operating Expenses. Operating expenses were $9.1 million for fiscal 1996,
$11.4 million for fiscal 1997 and $11.5 million for fiscal 1998. Research and
development expenses increased during the periods due mainly to hiring of
additional engineering personnel, while selling, general and administrative
expenses decreased during fiscal 1998 due primarily to a decrease in
administrative expenses associated with the decreased cellular airtime and
cellular telephone sales during the year.

Income from Operations. Income from operations decreased 97.4% from $2.7
million for fiscal 1996 to $0.1 million for fiscal 1997 due primarily to the
$2.9 million decrease in revenues and the $2.3 million increase in operating
expenses for fiscal 1997. Operating expenses increased in fiscal 1997 due
primarily to higher administrative costs associated with cellular airtime and
cellular telephone revenues in Puerto Rico and costs associated with evaluating
investment opportunities in China. Income from operations increased 1,339.1%
from $0.1 million for fiscal 1997 to $1.0 million for fiscal 1998 due primarily
to the $0.9 million increase in gross profit that resulted from the increased
sales of higher margin products. Operating expenses were essentially unchanged
for fiscal 1998 as research and development costs increased by $0.1 million,
while increased systems sales expenses were primarily offset by lower cellular
airtime and cellular telephone administrative costs resulting from our decision
to target higher quality customers.

Discontinued Operations. Discontinued operations represent the results of
operations of a former subsidiary of Cortelco that was spun off in March 1997
to the stockholders of our former parent, merged with Business Communications
Systems, Inc. and renamed "BCS Technologies, Inc." At the time of spin-off, the
subsidiary had experienced substantial net losses and our former parent decided
to concentrate its focus on realizing the Millennium's business potential.

Liquidity and Capital Resources

We have funded our operations primarily through cash generated from operations,
periodic borrowings under our existing credit facilities, a $3.0 million
subordinated convertible note financing and acquisition financing provided by
Alcatel in connection with the purchase of our business from Alcatel in 1990.

Net cash provided by operating activities was $1.6 million for fiscal 1996,
$1.1 million for fiscal 1997, $1.1 million for fiscal 1998, $1.2 million for
the nine months ended April 30, 1998 and $1.2 million for the nine months ended
April 30, 1999. Cash provided by operating activities in fiscal 1997 and fiscal
1998 primarily resulted from improved collection procedures implemented during
these years.

Net cash provided by (used in) investing activities was ($0.5) million for
fiscal 1996, ($0.9) million for fiscal 1997, ($0.2) million for fiscal 1998,
($0.5) million for the nine months ended April 30, 1998 and $2.8 million for
the nine months ended April 30, 1999. In each year, cash used in investing
activities was primarily attributable to purchases of equipment and, in fiscal
1997, to the purchase of $0.3 million of software applications for the
Millennium. The $2.8 million provided by investing activities for the nine
months ended April 30, 1999 was due primarily to the $3.1 million cash balance
of BCS on the date of the acquisition. To the extent that we continue to grow
our research and development activities and invest in new technologies in the
future, we expect net cash used in investing activities will increase.

Net cash used in financing activities was $1.1 million for fiscal 1996, $0.2
million for fiscal 1997, $1.1 million for fiscal 1998, $0.9 million for the
nine months ended April 30, 1998 and $2.3 million for the nine months ended
April 30, 1999. Cash used in financing activities in the year ended July 31,
1998 consisted primarily of a decrease in outstanding checks, repayments under
the revolving credit line and partial repayment of a note to our former parent
company, Cortelco Systems Holding Corporation. The primary source of cash from
financing activities in fiscal 1997 was a $3.0 million subordinated convertible
note financing. The net cash used in financing transactions for the nine months
ended April 30, 1999 was due primarily to the $2.0 million loan made to CSHC to
retire the acquisition financing provided by Alcatel. See "Certain
Transactions."

In July and August 1997, we entered into two credit facilities with Foothill
Capital which allows us to borrow up to an aggregate of $9.0 million based on
accounts receivable and inventory levels. As of

                                       22
<PAGE>


April 30, 1999, there was $2.6 million outstanding under these credit
facilities which will be repaid using the net proceeds from this offering. See
note 11 to our consolidated financial statements.

We believe that the proceeds from this offering, together with available
funds, anticipated cash flows from operations and our line of credit, will
satisfy our projected working capital and capital expenditure requirements at
least through fiscal 2000. To the extent that we grow more rapidly than
expected in the future, we may need additional cash to finance our operating
and investing activities.

Year 2000 Compliance

The Year 2000 issue is the result of computer programs written using two
digits rather than four to define the applicable year (the "Year 2000 Issue").
Computer programs that have such date-sensitive software may recognize a date
using "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.

We are heavily dependent upon the proper functioning of our own computer or
data-dependent systems. This includes, but is not limited to, our systems in
information, business, finance, operations and service. Any failure or
malfunctioning on the part of these or other systems could adversely affect us
in ways that are not currently known, discernible, quantifiable or otherwise
anticipated by us.

Our operations are also dependent on the Year 2000 readiness of third parties
that do business with us. We are dependent on third-party suppliers of
infrastructure elements such as electric power and banking facilities. We do
not depend to any significant degree upon electronic transaction processing
with individual vendors for merchandise purchases, however, many of our
customers pay their invoices via electronic payment.

We have begun to evaluate those areas of our business that may be affected by
the Year 2000 Issue and have devised a plan to become Year 2000 compliant in a
timely manner which includes:

    . assessment of our own computer systems and the products we sell

    . communications with all our key suppliers, manufacturers and customers
      to determine the extent to which we are vulnerable to their failure to
      remedy their own Year 2000 Issues

    . correction, upgrade, replacement or retirement of our computer systems
      which are affected by the Year 2000 Issue

    . testing for and validation of our Year 2000 compliance

    . development of contingency plans to address situations that may result
      if we are unable to achieve Year 2000 compliance of our critical
      operations

Based on our assessment to date, we have determined that we will be required
to upgrade a portion of our software so that our computer systems will
function properly with respect to dates in the Year 2000 and thereafter. We
estimate that our information systems will be Year 2000 compliant by July
1999. We estimate that costs associated with the upgrade of existing computer
software will be less than $75,000. Costs incurred and expensed in the nine
months ended April 30, 1999 were less than $30,000. These costs related
entirely to modifications of existing software and represented approximately
10% of our information systems budget for information technology in the
period. Of the remaining portion of our estimated Year 2000 costs,
approximately $30,000 of the costs will be incurred in the fiscal quarter
ending July 31, 1999. We may address non-critical Year 2000 Issues beyond the
Year 2000. There is no assurance that total costs will not exceed our
estimates.

We are in communications with key suppliers, manufacturers and customers to
determine the extent to which we will be vulnerable to such parties' failure
to remedy their own Year 2000 Issues. We

                                      23
<PAGE>

currently have only limited information on the Year 2000 compliance of our key
suppliers, manufacturers and customers. Our business and results of operations
could experience material adverse effects if our key suppliers or manufacturers
were to experience Year 2000 Issues that caused them to delay production or
shipment of key components or systems. In addition, our results of operations
could be materially adversely affected if any of our key customers encounter
Year 2000 Issues that cause them to delay or cancel substantial purchase orders
or delivery of our product.

There can be no assurance that we will be able to upgrade any or all of our
major systems in accordance with our plan to address the Year 2000 Issue. In
addition, there can be no assurance that any such upgrades will effectively
address the Year 2000 Issue. If required upgrades are not completed or are
unsuccessful, there would be a material adverse impact on our operations.
Furthermore, there can be no guarantee that the systems of other companies on
which our own systems rely will be timely converted, or that a failure to
convert by another company, or a conversion that is incompatible with our
systems, would not have a material adverse effect on us. We intend to, but have
not yet established, a contingency plan detailing actions that will be taken in
the event that the assessment of the Year 2000 Issue is not successfully
completed on a timely basis. We believe that the worst case Year 2000 scenario
would involve disruption in utilities, transportation, and banking facilities.

                                    Business

Cortelco designs, develops and markets integrated enterprise communications
systems for routing and controlling the voice, video and data communications of
businesses and other organizations. Our solutions are primarily designed for
enterprises with complex communications needs and small and medium-sized
telephony installations, typically between 25 to 500 communications ports. We
serve a range of vertical markets such as education, retail, government
agencies, emergency-911 services and catalog sales. Some of our customers have
multiple installations networked together and are as large as national retail
chains or multi-location branches of the U.S. government. Our customers include
Bell Atlantic, Budget Rent-A-Car, Circuit City, the FAA, PETsMART and U-Haul.
Our products are installed in over 7,100 locations worldwide. In addition to
selling our products, we also resell cellular airtime, cellular telephones and
third-party voice communications systems in Puerto Rico. Our products have won
numerous awards, including "Best of Show" awards at CT Expo in 1997 and 1998
and "Product of the Year" awards in 1997 and 1998 from Call Center magazine and
in 1999 from Call Center Solutions magazine. On a pro forma basis, our revenues
increased 48.3% from $26.2 million for the nine months ended April 30, 1998 to
$38.9 million for the nine months ended April 30, 1999.

Our communications systems are based on two platforms, the Millennium and the
DSP Series. Both platforms are based on flexible, modular hardware and software
architectures that are easy to configure. Our platforms support multi-site
networking and other advanced features such as dynamic call routing,
interactive voice response, voicemail and computer telephony integration. The
Millennium is a full-function routing and control system that primarily serves
customers averaging approximately 110 communications ports per installation and
addresses a broad range of voice, video and data communications requirements.
The Millennium also includes automatic call distribution features. The DSP
Series is primarily an advanced automatic call distribution system that also
includes a full-function routing and control system. The DSP Series is
typically used in installations requiring advanced computer telephony
integration applications such as those used in sophisticated call centers. The
architecture of our platforms is designed to permit easy configuration and
subsequent upgrading to meet changing customer needs. Customer desired features
can be incorporated through the installation of optional add-in cards and
software. Millennium systems can be connected over the public service telephone
network or private data networks and can support ISDN based systems such as
videoconferencing. Both the Millennium and the DSP Series interface with a
variety of popular third-party products through standard protocols.

We also offer other products to provide our customers with cost-effective,
integrated communications solutions. For example, the Cortelco Voice Processing
System offers integrated, multi-lingual voice and fax messaging services across
multiple networked locations. Our Illuminations software package enables self-
service access to databases, such as product pricing information or school
course registration options, using touch-tone telephones or the Internet. We
also offer software that organizes call center data into real-time,
customizable, graphical user interfaces and reports for agents and supervisors.

Industry Overview

According to Dataquest, the U.S. private branch exchange and call center
systems markets totaled $5.7 billion in 1998. Traditionally, the voice
switching requirements of large enterprises have been addressed by private
branch exchange equipment. Enterprises with smaller installations that have not
been able to justify the expense of private branch exchange equipment have
utilized key telephone systems that, while more economical, have limited
functionality and scalability. Technology advances and the demands of
increasingly sophisticated customers are driving changes in today's

                                       25
<PAGE>

telecommunications equipment industry. Businesses and organizations have come
to rely on complex voice and data networks to meet mission critical needs.
Recent technology advances have resulted in the introduction of increasingly
sophisticated features and applications in enterprise communications systems
that extend beyond traditional voice switching. Enterprises of all sizes are
now demanding telecommunications systems with the latest features and
applications in order to meet their business objectives. These features include
dynamic call routing, computer telephony integration, support for the
convergence of voice and data networks, multi-site networking and mobile
workforce support.

Dynamic Call Routing

Advanced call routing capabilities have recently been introduced that
dynamically screen, distribute and queue incoming calls based on specific
caller information, such as the number dialed or the state from which the call
is made. The growing number of "1-800" and "1-900" mail order, e-commerce and
customer support centers, driven by a focus on customer service, is generating
increased demand for dynamic call routing capabilities. These capabilities,
originally available only in dedicated automatic call distribution systems for
large stand-alone call centers, are now available as optional features on
standard private branch exchange equipment, and are being used for more general
business applications in various departments, such as human resources and
customer support.

Computer Telephony Integration

Computer telephony integration is the combination of voice communications and
computing capabilities which link telephony equipment to voicemail servers,
telephone directories, customer information databases and PC applications.
Enterprises increasingly seek voice communications systems that can use
standard protocols to interface with numerous third-party computer
applications. Such integrated applications include interactive voice response,
call accounting and unified messaging. For example, computer telephony
integration applications can be used to personalize call handling based on a
customer database and other information provided from the business' data
network. When an incoming call is connected to the customer service agent,
pertinent information concerning the particular caller can be displayed on the
agent's monitor, enabling the agent to provide a prompt and informed response
to the customer.

Convergence of Voice and Data Networks

Advances in networking and computing technologies offer the prospect of
combining voice and data networks which until now have been built and operated
as separate networks. The ability to combine separate voice and data networks
into one converged network could improve functionality, reduce network
administration and provide cost savings. For example, the widespread
implementation of Internet Protocol-based data networks has led to the
development of voice-over-Internet Protocol ("voice-over-IP") technology that
permits transmission of voice communications over public or private Internet
Protocol networks. According to Dataquest, transmission of voice traffic over
Internet Protocol networks in smaller enterprises is projected to grow at a
compound annual growth rate of 313% to 18.8 billion minutes of use in 2000.

Multi-Site Networking

Enterprises are increasingly dependent on distributed voice and data networks
to support their operations across multiple locations. A networked voice
communications solution delivers voice communication functions across multiple
locations as an integrated system, thereby increasing productivity and user
convenience and reducing costs. For example, messaging can be centralized so
that voicemail, e-mail and faxes can be delivered seamlessly to all locations
across the network.

                                       26

Support for a Mobile Workforce

Today's work environment is characterized by the need for real-time
communications that support increasingly mobile workers. Employees need to have
access to, and be accessible through, the enterprise's communications network
to make informed decisions quickly, improve productivity and respond to
customer needs rapidly. Remote access capabilities also allow off-site workers
to access all functions of the enterprise's communications system as if they
were on-site.

Traditional voice communications systems were designed to provide a broad range
of capabilities, but were not designed to be readily adaptable. Implementing
new features and applications on these systems often requires substantial
development effort and the purchase of ancillary equipment. Further
customization may be necessary to meet the needs of a particular installation.
Given the expense of ancillary equipment and customized development and the
need to allocate development resources to support larger customers,
communications systems vendors have generally addressed the small to medium-
sized installation segment of the market with equipment that is often costly
and less flexible. Thus, while traditional private branch exchange systems have
been able to adapt to the changing needs of large installations, the complexity
of these systems has limited the ability of traditional vendors to provide
flexible and cost-effective communications solutions for small and medium-sized
installations.

The Cortelco Solution

Cortelco provides integrated communications systems flexible enough to meet the
immediate needs of enterprises with small to medium-sized installations, yet
scalable enough to accommodate these businesses and organizations as they grow.
Our systems are based on a general purpose bus architecture designed from the
outset to permit the dynamic addition and variation of inputs, outputs and
features through software and configuration of the system through add-in cards.
Our solution offers functionality previously not readily available or cost-
effective for small to medium-sized installations. Our communications platforms
provide advanced features at an affordable cost and without the need for
extensive specialized software and hardware or complex installation procedures.

The flexible architecture of our Millennium and DSP Series platforms is the
backbone for all of our products. Our comprehensive solutions are designed to
improve the productivity and efficiency of our customers by providing them with
a variety of communications capabilities, such as:

    . advanced call routing allowing for dynamic distribution of incoming
      voice, video and data traffic

    . easy integration of voice communications and computing capabilities

    . cost-effective multi-site networking

    . advanced mobility features to provide in-building and campus wireless
      communications and remote access by off-site workers

We believe that we have achieved significant advantages in the configurability
of and the ease of programming these capabilities and other new features
relative to many competitors. Our flexible core platforms and range of options
offer enterprises with small to medium-sized installations the combination of
features and functions that best suit their particular needs.

Strategy

Cortelco's objective is to provide comprehensive, cost-effective communications
systems for small and medium-sized installations in selected vertical markets.
Our strategy incorporates the following key elements:

                                       27
<PAGE>

Target Small to Medium-Sized Installations

We target enterprises with small to medium-sized installations, typically 25 to
500 communications ports, at one or more locations and that may have complex
communications needs. We focus our sales efforts on selected vertical markets
in which we have identified needs that can be especially well served by our
systems and are characterized by enterprises with small to medium-sized
installations, complex communications needs and cost-sensitivity. Our current
targeted vertical markets include education, retail, government agencies,
emergency-911 services and catalog sales. The inherent flexibility and
configurability of our Millennium and DSP Series platforms make us uniquely
suited to meet the needs of our targeted customers.

Provide Cost-Effective, Integrated Customer Solutions

We provide customers with cost-effective, integrated solutions for their voice
communications requirements, including solutions to seamlessly integrate their
voice and data networks. We believe our customers prefer to purchase integrated
solutions from a single vendor due to convenience, consistency of service, ease
of upgrade and vendor accountability. We offer an integrated family of
communications products that interface with a wide range of third-party
products through industry standard protocols, enabling us and our dealers to
configure and deliver complete, customized voice communications systems that
meet the specific needs of each customer.

Expand Distribution Capabilities

We are expanding both our direct sales force and our dealer network to more
aggressively pursue our target markets. Since April 30, 1998, we have increased
our sales force by approximately 48% and we plan further increases over the
next year. We believe our use of indirect sales channels is especially
effective because our dealers often have experience in our targeted vertical
markets and because our flexible platforms enable them to sell, configure and
service advanced features with relatively little expertise. As of April 30,
1999, we had approximately 130 authorized dealers and value added resellers. We
are also expanding our geographic coverage by recruiting new dealers, value
added resellers and strategic partners in the United States, the Caribbean and
Latin America.

Develop New Product Capabilities

We intend to continue to enhance our core product line and develop new features
and applications that leverage our existing Millennium and DSP Series
platforms, address emerging market needs and increase gross margins. For
example, we recently introduced new features and applications such as circuit
switched data capabilities for data intensive applications and PC-based phone
control. We expect to introduce several additional product capabilities during
1999, including:

    . integrated in-building and campus wireless capabilities which increase
      the range and maximum number of users on the existing Orbit Wireless
      Communications product and add desktop equivalent capabilities

    . unified messaging which provides integrated access to voice, fax and
      e-mail messages in a multi-site networked communications system

    . Internet Protocol capabilities such as voice-over-Internet Protocol
      ("voice-over-IP"), virtual private networks for voice and data
      applications and other Internet-based applications

    . Web-based virtual call center capabilities allowing agents and
      supervisors located anywhere in the world to access their call centers
      over the Internet

We are also developing our next generation automatic call distribution and
switching architecture to address the integration of emerging voice and data
communications technologies.

Cortelco offers the Millennium and the DSP Series, two feature-rich
communications platforms targeted at specific market segments. Each platform
provides advanced features that are easy to program and cost-effective due to
an innovative modular hardware design and flexible software. Both platforms
support multi-site networking and advanced features such as dynamic call
routing, interactive voice response, voicemail and computer telephony
integration. Our platforms share a suite of applications and hardware,
including voice processing systems, an in-building and campus wireless
communications system, a number of advanced computer telephony integration
products and digital handsets. Both platforms also interface to a range of
popular third-party products through standard protocols. These two
communications systems allow us to provide an integrated communications
solution for our target markets.

We also sell a variety of other products for use with our platforms. Our
Caribbean and Latin American Operations unit sells communications systems and
products produced by Cortelco and resells cellular airtime, cellular telephones
and third-party voice communications systems in Puerto Rico.

The Millennium

The Millennium is a fully-featured private branch exchange with automatic call
distribution capabilities, primarily targeting enterprises with small to
medium-sized installations. It can be expanded in a modular manner from 32 to
1,024 communications ports and supports up to 100 automatic call distribution
agents. Customers can increase the number of ports and add new features and
applications through the simple installation of add-in cards and software.
Dynamic call routing and control functions are provided by an integrated system
controller running a real-time operating system. PC-based applications and
system features are accessed via a serial interface. The Millennium can be
networked with Cortelco platforms at other sites via a digital network
interface.

The following is a diagram of the functional architecture of the Millennium
platform.

                          [Millennium Network Diagram]

                                       29
<PAGE>

We believe that the Millennium platform is well-suited to address the voice
switching needs of enterprises with small to medium-sized installations,
including schools and school districts, retail sales and service locations,
distribution centers, broadcast and extended health care facilities, government
agencies and small call centers. The key strengths of the Millennium are multi-
site networking, affordable automatic call distribution applications and server
capabilities.

Multi-Site Networking. Millennium systems can be connected across multiple
locations, creating a private communications network that operates as if all
sites were on a single system. Therefore, connected locations can share the
Millennium's flexible call routing capabilities and applications. For example,
networked Millennium systems employing our proprietary VoiceClusters technology
can share a single Cortelco Voice Processing System, simplifying system
management and ensuring answering and call routing consistency across
locations. Similarly, networked Millennium systems employing the recently
announced integrated Orbit Wireless Communications System at each location
enables use of the same wireless handset across all locations.

Affordable Automatic Call Distribution Applications. A standard feature of the
Millennium is automatic call distribution. The system's dynamic call routing
and report generation capabilities can be enhanced with an optional, real-time
automatic call distribution package that provides call center management data
collection and reporting capabilities for smaller call centers. The Millennium
RealTime Automatic Call Distributor received a "Product of the Year" award from
Call Center Solutions magazine in January 1999.

Server Capabilities. The Millennium can be used to perform a variety of server-
like functions. For example, the Millennium can be used as a protocol converter
between E1 trunks, communications links used primarily by European carriers,
and T1 trunks, communications links used primarily in North America. The
Millennium can also be used as a channel bank, a device which merges multiple
voice and data circuits into a single digital communications stream, or act as
the switch in a wireless local loop network. In addition, one Millennium system
at the hub can serve as the single entry point for T1, PRI (Primary Rate ISDN)
and dedicated fiber optic links for the entire enterprise.

The DSP Series

The DSP Series is a fully-featured automatic call distributor platform with
integrated private branch exchange capabilities, primarily targeting the call
center market and enterprises with larger installations. It can be expanded in
a modular manner from 8 to 3,500 communications ports and supports up to 1,000
automatic call distribution agents. Its call routing flexibility can support up
to 32,000 routes, each with 64 different steps. Customers can increase the
number of ports and add new features and applications through the simple
installation of add-in cards and software. Dynamic call routing and control
functions are provided by redundant Pentium PCs running a real-time Linux-based
operating system. PC-based applications and system features are accessed via an
integrated Ethernet LAN interface. The DSP Series can be networked with
Cortelco platforms at other sites via a digital network interface.

The following is a diagram of the functional architecture of the DSP Series
platform.

                          [DSP Series Network Diagram]

Our DSP Series is primarily designed for call centers across a broad range of
industries including financial services, utilities, catalog sales, service
bureaus and emergency-911 services. The DSP Series is designed to ensure
uninterrupted service by including redundant processing units and power
supplies and using a real-time Linux-based operating system. We believe the DSP
Series is one of the most powerful and economical systems available on a cost-
per-agent basis. The DSP Series won "Best of Show" awards at the 1997 and 1998
CT Expo and "Product of the Year" awards in 1997 and 1998 from Call Center
magazine and in 1999 from Call Center Solutions magazine.

The DSP Series provides the platform to handle, manage and improve all aspects
of call center management. Its advanced automatic call distribution
capabilities include real-time dynamic call routing, skill-based routing,
simultaneous queuing among multiple gates and multiple networked systems,
intelligent messages and caller identification number directed routing. The DSP
Series also provides a comprehensive, customizable report and display package
and can support computer

                                       31
<PAGE>

telephony integration applications for both inbound and outbound call center
solutions. We currently offer the DSP1000 and DSP2000. The DSP2000 is an
updated version of the DSP1000 which provides an upgrade path to 3,500
communications ports and support for a greater number of call center agents.
The key strengths of the DSP Series are advanced automatic call distribution
capabilities, host computer telephony integration and PC Phone Control with
ActiveX.

Advanced Automatic Call Distribution Capabilities. The advanced automatic call
distribution capabilities of the DSP Series include:

    . Home Agent--This feature allows an agent to call into the system from
      a touch-tone phone, sign-on and conduct business as if he or she were
      on-site. The home agent can perform all operations and enter all modes
      as any other on-site agent. Supervisor displays, historical data
      gathering and computer telephony integration applications work
      identically for off-site and on-site agents. Additionally, the home
      agent with a modem-connected PC can retrieve information from
      enterprise databases.

    . Automatic Agent Greetings (AgentVoice)--This feature allows an agent
      to pre-record a number of different greetings that can be played based
      upon a caller's identification number. The agent and the caller hear
      the greeting simultaneously, providing a "whisper announce"
      notification for the agent. Pre-recorded responses can be played on
      demand to provide consistent, automated answers to frequently-asked
      questions from callers. AgentVoice is particularly useful for high
      volume call centers and service bureaus in which agents answer calls
      for a variety of different businesses.

    . Intelligent Announcement System--This feature enables our customers to
      provide inbound callers with a number of customized interactive,
      promotional, informational, holiday, after hours and delay messages.
      In addition, it can provide the caller with real-time call statistics
      such as estimated wait time, number of calls waiting and number of
      agents available. Our customers can choose from a set of pre-recorded
      voices or create a personalized message from a touch-tone phone or a
      Microsoft Windows-based interface.

    . Agent Call Back--This feature allows a call center agent with
      automatic number identification capability to flag a call, enabling a
      caller who calls back within a given period of time to be routed to
      the agent who originally handled the call.

Host Computer Telephony Integration.  The DSP Series offers an applications
link for direct, redundant TCP/IP communications to host computers using
10/100BaseT Ethernet, a standard data networking protocol. This link allows
data and commands to flow between the DSP Series and multiple host computers,
permitting a networked implementation of a variety of enhanced applications
such as screen synchronization, automated outbound dialing, automatic number
identification screening and call routing. The link uses a standard Computer
Supported Telecommunications Application ("CSTA") protocol which functions with
many commercially available computer telephony integration protocols such as
Novell TSAPI, IBM Call Path and Dialogic CT Connect applications. Unlike other
similar competitive offerings, no intermediate computers are required for the
CSTA interface.

PC Phone Control with ActiveX.  PC Phone Control is a graphical user interface
for agents to access call center functions such as available/unavailable
status, group pickup, redial and multi-line support. The ActiveX component of
our PC Phone Control provides tools for developers of call center applications
to use a variety of programming languages, including C, C++, Borland Delphi,
Visual Basic and Java, to develop custom applications without the need to
understand complex computer telephony integration protocols. We have won
numerous awards for this product, including a "Best of Show" award at the 1998
CT Expo and a "Product of the Year" award in 1997 from Call Center magazine.

Other Products

We also offer a variety of other products for use with both the Millennium and
DSP Series.

Voice Processing System.  The Cortelco Voice Processing System manages voice
and fax messaging through integration of the telephone and messaging systems.
This system provides a full range of voice and fax messaging services across
networks running Microsoft NT, Novell NetWare, IBM OS/2 Warp and Artisoft
LANtastic. Our proprietary VoiceClusters technology links multiple Cortelco
Voice Processing System servers into a global messaging system, using existing
wide-area networks to exchange messages between systems. This capability
enables voice and fax message distribution to locations worldwide, improving
message access and reducing transmission costs and delivery time. The system
offers capabilities to support multiple languages simultaneously and language
preference can be programmed by system, group or individual users. The Cortelco
Voice Processing System is expandable from 4 to 48 ports and supports voicemail
applications for up to 3,000 mailboxes, the Millennium and DSP Series platforms
and many other voice communications platforms.

In-building Wireless Communications.  Cortelco's Orbit Wireless Communications
System utilizes micro-cellular technology in the 1.92 to 1.93 gigahertz
frequency band to provide a private digital wireless voice/data communications
network within a building or campus. The system consists of a controller, base
stations and user handsets and can be used with our systems or with any third-
party private branch exchange or key telephone system. These system components
are purchased and licensed from a third-party supplier under an OEM purchase
agreement. We recently announced a Millennium Wireless Services Card of our own
design which we expect to make available during the third calendar quarter of
1999. This add-in card and software enables full desktop equivalent features on
the Orbit wireless handsets and significantly increases the range of the system
and number of users it can simultaneously support. We plan to provide a similar
add-in card for the DSP Series. The Orbit Wireless Communications System won a
"Best of Show" award at the 1998 CT Expo.

Interactive Voice Response.  Cortelco's Illuminations packages are Interactive
Voice Response and Web-enabled self-service information retrieval packages
customized for certain vertical markets. We released the first Illuminations
package, Illuminations for Education, in August 1998. Illuminations for
Education supports such common applications as automated course registration,
automated attendance validation and grade reporting. We are considering the
development of additional packages for the e-commerce, call center, broadcast
and retail markets.

PC-Based Attendant Console.  The Navigator attendant console is a hardware and
software based answering and messaging package for use with our Millennium
system. The Navigator enhances an attendant's performance by presenting
appropriate answer phrases, associated company directories, current
availability status of individuals and other useful information with each
inbound call. Calls can be connected to desired parties, on- or off-site, with
a single keystroke or the click of a mouse. Messages can be taken for
unavailable parties or digital pagers can be dialed with preprogrammed callback
numbers displayed. The Navigator provides the attendant with the information
necessary to efficiently answer and process each call presented to the console.
The Navigator is particularly well-suited for multi-tenant applications. A new
version of this product, to be introduced in the third calendar quarter of
1999, provides the ability to integrate with popular e-mail packages such as
Microsoft Outlook. This product won a "Best of Show" award at the 1997 CT Expo.

Third-Party Products and Services in Puerto Rico

We resell cellular airtime, cellular telephones and third-party voice
communications systems in Puerto Rico. These third-party products include voice
communications systems from Hitachi and Lucent, sold under distributor
agreements for the Puerto Rico market. Cellular airtime services are resold
under agreements with CellularOne and GTE and cellular telephone equipment is
resold for a variety of equipment suppliers, including Ericsson, Motorola and
Nokia.

Customers

Cortelco's customers are typically enterprises with small to medium-sized
installations which often have complex communications needs. Many of these
customers are in selected vertical markets in which we have identified needs
that can be especially well served by our systems. These markets currently
include education, retail, government agencies, emergency-911 services and
catalog sales. Some of our customers have multiple installations networked
together and are as large as national retail chains, such as Circuit City and
U-Haul, or multi-location branches of the U.S. government, such as the FAA and
the U.S. Coast Guard.

For example, Circuit City, one of the nation's largest retailers of brand-name
consumer electronics equipment, has implemented our products in several hundred
stores throughout the United States. Circuit City's customer service centers
use the Millennium Real-Time Automatic Call Distributor package. The
Millennium's flexible call routing and automatic call distributor capabilities
and its easy installation, programming and setup were important factors for
Circuit City in choosing a Cortelco solution.

We have also sold over sixty DSP Series systems to the FAA for use in their
Automated Flight Service Stations. Whenever a general aviation pilot files a
flight plan, checks aviation weather or national airspace information, the call
is answered and routed through a DSP Series system. The DSP Series provides the
FAA with an automatic call distribution platform for applications such as
computer telephony integration, skill-based call routing and remote agents, as
well as full voice routing and control functionality.

Sales and Marketing

For the fiscal year ended 1998, approximately 70% of our pro forma revenues
were generated by our direct distribution channels and approximately 30% of our
pro forma revenues were generated by our indirect distribution channels. We use
a direct sales force to market our Millennium systems to national accounts and
the federal government and for all DSP Series system sales. Approximately 130
authorized dealers and value added resellers sell, install and service our
Millennium systems. We directly install, maintain and support our DSP Series
systems. All of our sales in Puerto Rico are made through our direct sales
force. We also offer systems integration services and customized system
development. As of April 30, 1999, we had approximately 74 sales and marketing
personnel. We have increased the number of sales and marketing personnel by
approximately 48% since 1998 and anticipate further increases in the future.

Through our office in San Juan, Puerto Rico, our Caribbean and Latin American
Operations unit expects to develop a network of authorized dealers for sales
and service of the Millennium and DSP Series product lines in countries in the
Caribbean, Central America and the northern portion of South America.
Additionally, we expect to open an office in Santiago, Chile, which will
develop and manage a network of authorized dealers for sales and service in
Argentina, Bolivia, Chile, Equador and Peru.

Our marketing efforts focus on building brand awareness and increasing sales to
customers directly and through our dealer network and value added resellers. We
seek to educate customers in our targeted vertical markets about the benefits
of our flexible product platforms and integrated communications solutions and
the quality of our customer support and services.

Research and Development

Our research and development efforts focus on enhancing our core product lines
and developing the next generation automatic call distribution and switching
architecture. We routinely conduct market research and solicit input from our
customers and a select set of dealers as an integral part of our product
planning. Current product initiatives include:

    . Platform Extensions--Extend and enhance the capabilities of the
      Millennium and DSP Series platforms. Examples include: unified
      messaging support, enhanced integration of our Cortelco Voice
      Processing System, an Orbit Wireless Services Card for the DSP Series
      and 2-wire telephone support for the Millennium.

    . Internet-Based Products--Integrate Internet capabilities into
      traditional switched telephony applications. Examples include: voice-
      over-Internet Protocol ("voice-over-IP") and Web-based virtual call
      center capabilities.

    . Computer Telephony Integration Applications--Extend programming
      interfaces, develop applications and certify third-party computer
      telephony integration products for targeted vertical markets. Examples
      include: TAPI standard computer telephony integration interface,
      Illuminations packages for call centers and retail markets and
      enhanced PC Phone Control with ActiveX.

    . Next Generation Core Products--Establish design concepts and
      architecture for new core products that will extend and enhance the
      capabilities of our current Millennium and DSP Series products.
      Consistent with our strategy, new core products will be based on an
      open architecture, will support a broader set of industry standard
      protocols than our current products and will more fully integrate
      emerging voice and data technologies. Examples of the new technologies
      and capabilities we are addressing include: a local area network
      telephony gateway, an Internet Protocol-based dynamic call routing
      server for voice and data, frame relay and asynchronous transfer mode
      protocol support, and local area network-based Internet Protocol
      telephones.

As of April 30, 1999, we had 32 employees engaged in research and development.
We have increased the total number of engineers by approximately 25% since
1998. We expect to continue to increase the number of our research and
development employees at a faster rate than other areas and to focus these
additional resources on our new product development initiatives. In particular,
we will expand our capability to design and develop new software features which
are based on industry standard network interfaces, such as asynchronous
transfer mode and frame relay, and industry standard operating systems, such as
Linux, Unix and Windows NT.

Manufacturing

We currently rely on two contract electronic manufacturers to produce the
Millennium, CMC Industries, Inc. in Corinth, Mississippi and Pensar Corporation
in Appleton, Wisconsin. Both contract manufacturers perform printed circuit
board assembly and soldering, in-circuit and functional testing and packaging.
We believe that CMC and Pensar have sufficient capacity and technical
capabilities to respond to foreseeable increases in customer demand and
advances in in-process technology. After final assembly by either manufacturer,
we inspect and perform quality assurance testing at our facility in Corinth,
Mississippi prior to shipment to our dealers or customers. Our contract with
CMC provides for the purchase of units through purchase orders with pricing to
be negotiated annually. The term of the contract is from August 1, 1998 through
July 31, 1999 with one year renewals upon written notice by Cortelco. We make
purchases from Pensar through purchase orders.

Due to the customized nature of call center installations, each DSP Series sys-
tem is custom-configured at our facility in Kennesaw, Georgia. We use various
contract electronic manufacturers to manufacture

                                       36
<PAGE>

line cards, trunk cards and other DSP Series components and subassemblies. We
receive, inspect and test components and subassemblies at our Kennesaw facili-
ty. We then assemble and test each DSP Series system, configured in accordance
with the customer's order, and ship the product directly to the customer's
site.

We are dependent on certain key suppliers for a number of our product
components. For example, we rely on Siemens for our primary digital signal
processors and chip sets, Natural Microsystems to supply the voice processors
for our Cortelco Voice Processing System and CTP Systems for our Orbit wireless
handsets and base stations. Our contract electronic manufacturers use standard
components and subassemblies manufactured to our specifications. We make
purchases from these suppliers through purchase orders. Interruptions in the
availability of components from our key suppliers could result in delays or
reductions in product shipments, which could damage our customer relationships
and have an adverse effect on our operating results. We could also have
difficulties finding alternate suppliers or modifying product designs to use
alternative components.

Competition

Our principal competitors include Lucent Technologies, Mitel, NEC, Nortel
Networks and Siemens in the voice communications equipment market and Aspect
Telecommunications and Rockwell Electronic Commerce in the call center market.
We also compete with vendors in markets for our ancillary products, such as
voicemail, wireless communications and computer telephony integration
applications. As voice and data communications networks converge, data
equipment vendors such as Cisco Systems and 3Com may also compete in our
market. In addition, alliances and mergers between telecommunications and
computer companies may strengthen our competitors' positions or result in new
entrants into our market.

Many of our current and potential competitors have significantly greater
financial, technical, marketing, customer service and other resources, greater
name recognition and a larger installed customer base than we do. As a result,
our competitors may be able to respond to new or emerging technologies and
changes faster than we can. They may also be able to devote greater resources
to the development, promotion and sale of their products. Actions by our
competitors could result in price reductions, reduced margins and loss of
market share, any of which would have a material adverse effect on our
financial condition. There can be no assurance that we can compete successfully
against our competitors or that competitive pressures would not have a material
adverse effect on our financial condition and results of operations.

Intellectual Property

Cortelco relies on patent, trademark, copyright, trade secret protection and
confidentiality and license agreements with its employees, clients, partners
and others to protect its proprietary rights. We currently have 23 patents
issued in the United States and additional patents pending. There can be no
assurance that any patent applications now pending or hereafter filed by
Cortelco will result in patents being issued.

The patent position of technology companies involves complex legal and factual
questions and, therefore, their validity and enforceability cannot be predicted
with certainty. There can be no assurance that the steps taken by Cortelco to
protect its proprietary rights will be adequate or that third parties will not
infringe or misappropriate our patents, trade secrets, trademarks and similar
proprietary rights. Furthermore, there can be no assurance that others will not
independently develop similar technologies or duplicate any technology
developed by Cortelco.

A failure by Cortelco to protect its intellectual property could have a
material adverse effect on its business, financial condition and results of
operations. In addition, litigation may be necessary in the future to enforce
our intellectual property rights, protect our trade secrets or determine the
validity and

                                       37
<PAGE>

scope of the proprietary rights of others. Such litigation could result in
substantial costs and diversion of management and technical resources, which
could have a material adverse effect on our business, financial condition and
results of operations.

      for our DSP Series engineering, manufacturing operations and quality
      assurance departments

    . San Juan, Puerto Rico--approximately 15,000 square feet of office
      space for our Caribbean and Latin American Operations unit

    . Corinth, Mississippi--approximately 11,000 square feet of warehouse
      space for our Millennium manufacturing operations and quality
      assurance departments

    . Englewood, Colorado--approximately 7,000 square feet of office space
      for ACD Business Operations unit sales and marketing and customer
      support departments

    . Guelph, Ontario, Canada--approximately 5,000 square feet of office
      space for a software engineering group

We expect to relocate our headquarters to a larger facility in Memphis,
Tennessee in 2000. We believe that these facilities will be adequate to
accommodate our needs for the foreseeable future.

Employees

As of April 30, 1999, we employed approximately 243 people, including
approximately 74 in sales and marketing, approximately 32 in research and
development, approximately 75 in service, technical support and training,
approximately 24 in manufacturing operations and quality assurance and
approximately 38 in finance and administration. We also employ independent
contractors and other temporary employees. None of our employees is represented
by a labor union, and we consider our employee relations to be good.
Competition for qualified personnel in our industry is intense, particularly
for qualified service technicians and software engineers trained in computer
telephony integration and other technical staff. We believe that our future
success will depend in part on our ability to attract, hire and retain
qualified personnel.

Legal Proceedings

In the ordinary course of our business, we may from time to time be involved in
litigation with employees, customers and others. In July 1998, we were served
with a complaint by CBC Distribution & Marketing, Inc. ("CDM"), alleging
essentially that a Millennium system purchased by CDM failed to function as
represented. The complaint, which also named our dealer, Technicom
Communications, Inc., and CDM's insurance carrier as defendants, seeks actual
damages of approximately $1.5 million due to disruption of its fantasy football
pool operations plus punitive damages and attorneys'
fees. CDM later amended the complaint to add Sprint International
Communications as a defendant. CDM's insurance carrier also filed a cross-claim
against us. CDM's claim against its insurance carrier and the insurance
carrier's cross-claim against us have since been voluntarily dismissed. We
believe that this litigation is without merit and will not have a material
adverse effect on our business.

In addition, in November 1998, WSI, Inc., as debtor in possession in a chapter
XI bankruptcy proceeding, filed an action against Cortelco Puerto Rico,
Cortelco Systems Holding Corporation and David S. Lee, one of our directors, in
bankruptcy court. WSI is a distributor of telecommunications systems in Puerto
Rico. The complaint essentially alleges that the defendants misused
confidential information and otherwise engaged in unfair competition with WSI
by attempting to discredit WSI with Lucent Technologies, Inc. and WSI's
customers in Puerto Rico and to hire WSI employees. The complaint seeks damages
in excess of $15.0 million plus costs and attorneys' fees. We believe that this
litigation is without merit and will not have a material adverse effect on our
business.

Committees of the Board of Directors

Our board of directors consists of six members, including our Chief Executive
Officer. In accordance with the terms of our certificate of incorporation, the
terms of office of the board of directors will be divided into three classes:
Class I, whose term will expire at the annual meeting of stockholders to be
held in 2000, Class II, whose term will expire at the annual meeting of
stockholders to be held in 2001, and Class III, whose term will expire at the
annual meeting of stockholders to be held in 2002. The Class I directors are
Stephen R. Bowling and Jenny Hsui Theleen, the Class II directors are Robert P.
Dilworth and David S. Lee, and the Class III directors are W. Frank King and J.
Michael O'Dell. At each annual meeting of stockholders after the initial
classification, the successors to directors whose terms will then expire will
be elected to serve from the time of election and qualification until the third
annual meeting following election. Any additional directorships resulting from
an increase in the number of directors will be distributed among the three
classes so that, as nearly as possible, each class will consist of one-third of
the directors.

Our board of directors has established an audit committee and a compensation
committee. The audit committee consists of independent directors Stephen R.
Bowling, Robert P. Dilworth and Jenny Hsui Theleen. The audit committee makes
recommendations to the board regarding the selection of independent auditors,
reviews the results and scope of the audit and other services provided by the
Cortelco's independent auditors, and reviews and evaluates Cortelco's audit and
control functions. The compensation committee consists of Stephen R. Bowling,
W. Frank King, David S. Lee and Jenny Hsui Theleen.

Director Compensation

Directors currently do not receive any cash compensation for services provided
as a board member but are reimbursed for out-of-pocket expenses they incur in
connection with attendance at board meetings. Pursuant to the 1997 Equity
Incentive Plan, Robert P. Dilworth and W. Frank King were each granted an
option to purchase 18,000 shares of common stock at an exercise price of $0.70
per share in July 1998 and September 1998, respectively, and an option to
purchase 17,027 shares of common stock at an exercise price of $6.50 per share
in December 1998. Directors are eligible to receive discretionary option grants
pursuant to the 1999 Equity Incentive Plan and employee directors will also be
eligible to participate in the 1999 Employee Stock Purchase Plan. See "--Stock
Incentive Plans."

Compensation Committee Interlocks and Insider Participation

In April 1998, our board of directors established a compensation committee. The
compensation committee is responsible for approving all compensation
arrangements for our officers and for

                                       42
<PAGE>

administering our employee stock option and stock purchase plans. In the last
fiscal year, the compensation committee was composed of Stephen R. Bowling,
David S. Lee and Jenny Hsui Theleen. W. Frank King joined the compensation
committee in February 1999. Other than Stephen R. Bowling, who served as
Cortelco's President from 1994 to October 1997 and as Cortelco's Chief
Executive Officer from 1994 to April 1998, none of the members of the
compensation committee are, or have ever been, officers or employees of
Cortelco. Prior to the formation of the compensation committee, all decisions
regarding compensation arrangements for our officers were made by the board of
directors. See "Certain Transactions."

Executive Compensation

The following table sets forth certain information concerning the compensation
earned for the fiscal year ended July 31, 1998 for (a) Cortelco's Chief
Executive Officer and (b) each other executive officer of Cortelco whose total
salary and bonus exceeded $100,000 for services rendered to Cortelco and its
subsidiaries during the fiscal year 1998 (the "Named Executive Officers"). For
information regarding terms of the stock options, see "--Stock Incentive
Plans."

The annual compensation of each of Robert R. Cash, David M. Fredrick and Sergio
R. Moren exceeds $100,000. However, because each of the above individuals were
hired during fiscal year 1998, their total compensation earned as of the end of
fiscal year 1998 did not exceed $100,000 and therefore they are not included in
the following table as Named Executive Officers. J. Michael O'Dell joined
Cortelco as President and Chief Operating Officer in October 1997 and became
the Chief Executive Officer of Cortelco in April 1998. Stephen R. Bowling
previously served as President of Cortelco until October 1997 and Chief
Executive Officer until April 1998.

Option Grants in Last Fiscal Year

The following table sets forth each grant of stock options made during the
fiscal year ended July 31, 1998 to each of the Named Executive Officers.
Options generally vest at a rate of 12.5% beginning on the date six months
after the vesting commencement date and the remaining options vest in equal
installments on a monthly basis over a three and one-half year period
thereafter. These options have a term of 10 years.

The potential realizable value is calculated based on the term of the option at
the time of grant, which is 10 years. Stock price appreciation of 5% and 10% is
assumed pursuant to rules promulgated by the SEC and does not represent our
prediction of our stock price performance. The potential realizable value at 5%
and 10% appreciation is calculated by assuming that the exercise price on the
date of

                                       43
<PAGE>


grant appreciates at the indicated rate for the entire term of the option and
that the option is exercised at the exercise price and sold on the last day of
its term at the appreciated price.

Aggregated Options Exercised in Fiscal 1998 and Year-End Option Values

The following table sets forth, for the Named Executive Officers, the shares
acquired and the value realized on each exercise of stock options during the

unexercised options held by the Named Executive Officers at July 31, 1998.
Options generally vest at a rate of 12.5% on the date six months after the date
of grant and the remaining options vest in equal installments on a monthly
basis over a three and one-half year period thereafter. These options have a
term of 10 years. There was no public trading market for the common stock as of

Stock Incentive Plans

1999 Equity Incentive Plan

In April 1999, our board of directors adopted, and the stockholders approved,
the 1999 Equity Incentive Plan (the "1999 Incentive Plan"). There is currently
an aggregate of 2,000,000 shares of common stock authorized for issuance under
the 1999 Incentive Plan. The 1999 Incentive Plan provides for the grant of
incentive stock options, as defined under the Internal Revenue Code of 1986, as
amended (the "Code"), to employees and nonstatutory stock options, restricted
stock purchase awards, stock bonuses and stock appreciation rights to
employees, directors and consultants of Cortelco and its affiliates. The 1999
Incentive Plan is administered by a committee appointed by the board of
directors which determines recipients and types of awards to be granted,
including the exercise price, the number of shares subject to the award, the
vesting rate and the exercisability of awards.

The terms of options granted under the 1999 Incentive Plan may not exceed 10
years. The exercise price is determined by the board of directors, provided
that, the exercise price for an incentive stock

                                       44
<PAGE>

option cannot be less than 100% of the fair market value of the common stock on
the date of the option grant, and the exercise price for a nonstatutory stock
option cannot be less than 85% of the fair market value of the common stock on
the date of the option grant. Generally, the optionee may not transfer a stock
option other than by will or the laws of descent or distribution unless the
optionee holds a nonstatutory stock option that provides for transfer in the
stock option agreement. However, an optionee may designate a beneficiary who
may exercise the option following the optionee's death. An optionee whose
service relationship with Cortelco or any affiliate ceases for any reason may
exercise vested options for the term provided in the option agreement.

No incentive stock option may be granted to any person who, at the time of the
grant, owns, or is deemed to own, stock possessing more than 10% of the total
combined voting power of Cortelco or any affiliate of Cortelco, unless the
option exercise price is at least 110% of the fair market value of the stock
subject to the option on the date of grant and the term of the option does not
exceed five years from the date of grant. In addition, the aggregate fair
market value, determined at the time of grant, of the shares of common stock
with respect to which incentive stock options are exercisable for the first
time by an optionee during any calendar year, under all Cortelco stock plans
and its affiliates, may not exceed $100,000.

When Cortelco becomes subject to Section 162(m) of the Code, which denies a
deduction to publicly held corporations for certain compensation paid to
specified employees in a taxable year to the extent that the compensation
exceeds $1,000,000, no person may be granted options under the 1999 Incentive
Plan covering more than 500,000 shares of common stock in any calendar year.

Shares subject to stock awards that have expired or otherwise terminated
without having been exercised in full again become available for the grant of
awards under the 1999 Incentive Plan. Restricted stock purchase awards granted
under the 1999 Incentive Plan may be granted pursuant to a repurchase option in
favor of Cortelco in accordance with a vesting schedule and at a price
determined by the board of directors. Stock bonuses may be awarded in
consideration of past services without a purchase payment. Unless otherwise
specified, rights under a stock bonus or restricted stock bonus agreement
generally may not be transferred other than by will or the laws of descent and
distribution during such period as the stock awarded pursuant to such an
agreement remains subject to the agreement.

If there is any sale of substantially all of Cortelco's assets, any merger,
reverse merger or any consolidation in which Cortelco is not the surviving
corporation, or any acquisition by certain persons, entities or groups of 50%
or more of Cortelco's stock, all outstanding awards under the 1999 Incentive
Plan either will be assumed or substituted by any surviving entity. If the
surviving entity determines not to assume or substitute such awards, the
vesting provisions of such stock awards will be accelerated and the awards
terminated if not exercised prior to the such transaction.

As of April 30, 1999, no stock bonuses or restricted stock awards had been
granted, options to purchase 987,982 shares of common stock were outstanding,
no options had been exercised and 1,012,018 shares remained available for
future grants pursuant to the 1999 Incentive Plan. The 1999 Incentive Plan will
terminate in April 2009.

1997 Equity Incentive Plan

In April 1998, our board of directors and stockholders approved the 1997 Stock
Incentive Plan (the "1997 Incentive Plan"), which provides for the grant of
incentive stock options, nonqualified stock options and restricted stock awards
to employees and consultants. A maximum of 450,000 shares of common stock have
been reserved for issuance under the 1997 Incentive Plan. In addition, the
aggregate fair market value, determined at the time of grant, of the shares of
common stock with

                                       45
<PAGE>

respect to which incentive stock options are exercisable for the first time by
an optionee during any calendar year, under all stock plans of Cortelco and its
affiliates, may not exceed $100,000.

The 1997 Incentive Plan is administered by the board of directors, which has
the authority to determine which eligible individuals are to receive options or
restricted stock awards, the terms of such options or awards, the status of
such options as incentive or nonqualified stock options under the federal
income tax laws, including the number of shares, exercise or purchase prices
and exercisability, vesting schedule and the time, manner and form of payment
upon exercise of an option. The exercise price of options granted under the
1997 Incentive Plan is determined by the compensation committee. The options
expire after a specified period that may not exceed ten years or in the case of
a stockholder holding greater than 10% of the voting power, five years. As of
April 30, 1999, options to purchase 333,505 shares were outstanding, no options
had been exercised, and 116,495 shares remained available for future grants
pursuant to the 1997 Incentive Plan. The 1997 Incentive Plan will terminate in
April 2008. Our board of directors has determined that no further options will
be granted under the 1997 Incentive Plan after the completion of this offering.

1997 Equity Incentive Plan of BCS Technologies, Inc.

In April 1999, in connection with the acquisition of BCS, we assumed the 1997
Stock Incentive Plan of BCS, (the "BCS 1997 Incentive Plan"), which provides
for the grant of incentive stock options, nonqualified stock options and
restricted stock awards to employees and consultants. A maximum of 96,495
shares of our common stock have been reserved for issuance under the BCS 1997
Incentive Plan. As of April 30, 1999, options to purchase 94,279 shares were
outstanding, no options had been exercised, and 2,216 shares remained available
for future grants pursuant to the BCS 1997 Incentive Plan. The BCS 1997
Incentive Plan will terminate in January 2007. Our board of directors has
determined that no further options will be granted under the BCS 1997 Incentive
Plan after the completion of this offering.

1999 Employee Stock Purchase Plan

In April 1999, our board of directors and stockholders approved the 1999
Employee Stock Purchase Plan, which enables eligible employees to acquire
shares of common stock through payroll deductions. The 1999 Employee Stock
Purchase Plan is intended to qualify as an "employee stock purchase plan" under
Section 423 of the Code. The initial offering period will start on the date of
this prospectus and end on August 31, 2000, with purchase dates on February 29,
2000 and August 31, 2000, unless otherwise determined by our board of
directors. Each offering under the 1999 Employee Stock Purchase Plan after the
initial offering will run for one year, unless otherwise determined by the
board of directors prior to the beginning of such offering. During each
offering period, an eligible employee may select a rate of payroll deduction of
up to 15% of compensation. The purchase price for the common stock purchased
under the 1999 Employee Stock Purchase Plan is 85% of the lesser of the fair
market value of the shares on the first day or the purchase date. An aggregate
of 250,000 shares of common stock have been reserved for issuance under the
1999 Employee Stock Purchase Plan.

Employment Agreement

With the exception of David M. Fredrick, Vice President/General Manager of ACD
Business Operations, none of our executive officers has an employment
agreement, and each of such executive officers serves at the discretion of our
board of directors. On April 12, 1999, Cortelco entered into an employment
agreement with Mr. Fredrick. Pursuant to the terms of such agreement, Mr.
Fredrick is to receive annual salary of $165,000 in 1999 and an annual salary
of $175,000 in 2000. Mr. Fredrick will receive an option to purchase 70,000
shares of common stock, 60,000 shares of which vest on January 2, 2001 and
10,000 shares of which vest on January 2, 2002.

401(k) Plan

Effective July 15, 1990, as amended on October 1, 1995, our board of directors
adopted an employee savings and retirement plan (the "401(k) Plan") covering
certain of our employees. Pursuant to the 401(k) Plan, eligible employees may
elect to reduce their current compensation by up to the lesser of 16% of such
compensation or the statutorily prescribed annual limit ($10,000 in 1998) and
have the amount of such reduction contributed to the 401(k) Plan. Cortelco may
make contributions equal to 50% of the first 6% of the total of an employee's
elective contribution and/or their after-tax employee contribution up to a
maximum of $2,000 to the 401(k) Plan on behalf of eligible employees.
Additionally, we may make an additional non-matching contribution on a
discretionary basis on behalf of all eligible employees. The 401(k) Plan is
intended to qualify under Section 401 of the Code so that contributions by
employees or by Cortelco to the 401(k) Plan, and income earned on the 401(k)
Plan contributions, and so that contributions by Cortelco, if any, will be
deductible by us when made. The trustee under the 401(k) Plan, at the direction
of each participant, invests the 401(k) Plan employee salary deferrals in
selected investment options. We made contributions to the 401(k) Plan in fiscal
1998 and in the first quarter of fiscal 1999. We presently expect to make
monthly contributions to the 401(k) Plan during fiscal 1999.

Limitation of Liability and Indemnification Matters

Our bylaws provide that we will indemnify our directors and executive officers
and may indemnify our other officers, employees and agents to the fullest
extent permitted by Delaware law. We are also empowered under our bylaws to
enter into indemnification contracts with our directors and executive officers
and to purchase insurance on behalf of any person we are required, or
permitted, to indemnify. Pursuant to this provision, we expect to enter into
indemnity agreements with each of our directors and executive officers.

In addition, our certificate of incorporation provides that, to the fullest
extent permitted by Delaware law, our directors will not be liable for monetary
damages for breach of the directors' fiduciary duty of care to us and our
stockholders. This provision in the certificate of incorporation does not
eliminate the duty of care, and in appropriate circumstances equitable remedies
such as an injunction or other forms of non-monetary relief would remain
available under Delaware law. Each director will continue to be subject to
liability for breach of the director's duty of loyalty to us, acts or omissions
not in good faith or involving intentional misconduct, knowing violations of
law, for any transaction from which the director derived an improper personal
benefit, improper transactions between the director and us and improper
distributions to stockholders and loans to directors and officers. This
provision also does not affect a director's responsibilities under any other
laws, such as the federal securities laws or state or federal environmental
laws.

We expect to enter into agreements with our directors and officers that require
us to indemnify such persons against expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred (including expenses of a
derivative action) in connection with any proceeding, whether actual or
threatened, to which any such person may be made a party by reason of the fact
that such person is or was a director or officer of Cortelco or any of its
affiliated enterprises, provided such person acted in good faith and in a
manner such person reasonably believed to be in, or not opposed to, the best
interests of Cortelco and, with respect to any criminal proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The
indemnification agreements also set forth certain procedures that will apply in
the event of a claim for indemnification thereunder.

                       Principal and Selling Stockholders

The following table sets forth certain information with respect to the
beneficial ownership of Cortelco's outstanding common stock as of April 30,
1999 and as adjusted to reflect the sale of the common stock being offered

    . each person (or group of affiliated persons) who is known by Cortelco
      to own beneficially more than 5% of the common stock

    . each of the Named Executive Officers

    . each of the directors

    . all directors and executive officers of Cortelco as a group

    . each of Cortelco's current stockholders who is expected to sell shares
      in the offering.

Beneficial ownership is determined in accordance with the rules of the SEC and
generally means sole or shared power to vote or direct the voting or to dispose

completion of this offering assuming no exercise of the underwriters' over-
allotment option. If the underwriters' over-allotment option is exercised in
full, Cortelco and certain stockholders will sell up to 3,588,000 shares of
common stock, and 11,412,114 shares of common stock will be outstanding after
the completion of this offering.

                              Certain Transactions

Prior to April 1999, Cortelco was a subsidiary of Cortelco Systems Holding
Corporation and from time to time engaged in intercompany transactions with its
parent and affiliates. See note 15 to our consolidated financial statements.
The Cortelco common stock held by our parent company was pledged to secure a
debt obligation in the amount of $3,600,000 as of December 31, 1998. In order
to release this stock from the pledge so that Cortelco Systems Holding
Corporation could distribute it to the holders of its capital stock and
facilitate the acquisition of BCS, an agreement was entered into with the
lender on February 25, 1999 to repay the remaining principal of this obligation
in several installments, the last of which was paid on May 28, 1999. We loaned
$2,600,000 at an interest rate equal to the prime rate plus 1.5% to Cortelco
Systems Holding Corporation to be used for these payments. We have also
declared dividends in the amount of $2,658,000, payable upon completion of this
offering, which will be applied to repaying the principal of the loan.
Following release of the pledge, Cortelco Systems Holding Corporation
distributed a total of 2,856,944 shares of our common stock to its stockholders
in April 1999 (the "Spin-Off"). In connection with the Spin-Off, Cortelco
Systems Holding Corporation distributed: 1,137,364 shares of common stock to
David S. Lee, chairman of Cortelco; 612,530 shares to CMC Industries; and 4,667
shares to Stephen R. Bowling, a director of Cortelco. David S. Lee is also
Chairman and a principal stockholder of Cortelco Systems Holding Corporation.
Stephen R. Bowling is also President, Chief Executive Officer and a director of
Cortelco Systems Holding Corporation. CMC Industries is affiliated with
Cortelco through common stock ownership.

Pursuant to a Convertible Note Purchase Agreement dated as of July 31, 1997, we
sold a convertible promissory note in the aggregate principal amount of
$3,000,000 to ChinaVest, a principal stockholder. The note matures on July 31,
2002 and accrues interest at the rate of 8.0%, payable on the maturity date or
sixty days following the date of conversion. On April 12, 1999, in accordance
with the terms of the note, ChinaVest converted $686,000 of outstanding
principal into 1,463,206 shares of Series A Convertible Preferred Stock. The
Series A Convertible Preferred Stock automatically converts into 1,434,894
shares of our common stock upon completion of this offering. The remaining
principal amount of $2,314,000, plus accrued interest, outstanding under the
note will be paid from the net proceeds of this offering. Jenny Hsui Theleen, a
director of Cortelco, is a managing director of ChinaVest.

In July 1997, we loaned Cortelco Systems Holding Corporation the principal
amount of $3,184,000. The note accrues interest at the rate of 8.0% per annum.
In April 1999, we repurchased 250,000 shares of our common stock from Cortelco
Systems Holding Corporation in exchange for the cancellation of $2,500,000 of
the principal amount of the note. The remaining principal amount of $684,000,
plus accrued interest, is due in November 2000.

In October 1997, we loaned J. Michael O'Dell, our Chief Executive Officer and a
director, the principal amount of $132,000 in connection with relocation
expenses. J. Michael O'Dell repaid $61,000 of principal on the note in October
1998. The balance is due in October 1999.

In April 1998, we sold a Millennium system to a public television station for
$210,000. The funding for the purchase was based on a directed donation from
David S. Lee through the Asia Cultural Teachings Corporation, a charitable
foundation. David S. Lee is the honorary president of Asia Cultural Teachings
Corporation.

In April 1998, David S. Lee loaned Cortelco the principal amount of $250,000,
payable on demand. The note was non-interest bearing and was repaid in full in
October 1998. In February 1999, we

                                       50
<PAGE>

distributed a note receivable from David S. Lee in the amount of $250,000,
which had been recorded as an offset to stockholders equity, to Cortelco
Systems Holding Corporation as a dividend.

In April 1999, we declared and paid a stock dividend of 195,684 shares of
common stock.

In connection with the BCS acquisition, we issued 1,036,014 shares of our
common stock to David S. Lee, 636,518 shares to David M. Fredrick, 616,445
shares to Frank Naso, 453,562 shares to ChinaVest and 3,321 shares to Stephen
R. Bowling in exchange for their stockholdings in BCS. See "Company
Background." We also entered into employment agreements with David M. Fredrick
and Frank Naso. See "Management--Employment Agreements."

Since 1993, CMC Industries, Inc., a principal stockholder, has provided certain
manufacturing services on a non-exclusive basis. The current agreement with
CMC, dated as of August 1, 1998, expires on July 31, 1999, and is renewable
annually by Cortelco. David S. Lee is Chairman and a principal stockholder of
CMC. CMC announced on May 10, 1999 that it had signed a definitive agreement to
be acquired by ACT Manufacturing Inc.

We purchase single line phones from, and sell Millennium related products to,
Cortelco International, Inc., a wholly-owned subsidiary of Cortelco Systems
Holding Corporation. David S. Lee and Stephen R. Bowling are directors of
Cortelco International, Inc. In fiscal 1998, our purchases from Cortelco
International, Inc. totaled $85,000 and our sales totaled $188,000.

Cortelco believes that all of the transactions set forth above were made on
terms no less favorable to Cortelco than could have been otherwise obtained
from unaffiliated third parties. As a matter of policy, all future transactions
between Cortelco and any of its officers, directors or principal stockholders
will be approved by a majority of the board of directors, including a majority
of the independent and disinterested members of the board.

which have been filed as exhibits to our registration statement, of which this
prospectus is a part.

Upon the closing of this offering, our authorized capital stock will consist of
50,000,000 shares of common stock, $.001 par value per share, and 10,000,000

Common Stock

The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. The holders of
common stock are not entitled to cumulative voting rights with respect to the
election of directors, and as a consequence, minority stockholders will not be
able to elect directors on the basis of their votes alone. Subject to
preferences that may be applicable to any then outstanding shares of preferred
stock, holders of common stock are entitled to receive ratably such dividends
as may be declared by the board of directors out of funds legally available for
dividends. In the event of our liquidation, dissolution or winding up, holders
of the common stock are entitled to share ratably in all assets remaining after
payment of liabilities and the liquidation preference of the preferred stock,
if any, then outstanding. Holders of common stock have no preemptive rights and
no right to convert their common stock into any other securities. There are no
redemption or sinking fund provisions applicable to the common stock.

Preferred Stock

The board of directors has the authority, without further action by the
stockholders, to issue any undesignated shares of preferred stock in one or
more series and to fix the rights, preferences, privileges and restrictions of
any shares of preferred stock, including dividend rights, conversion rights,
voting rights, terms of redemption, liquidation preferences, sinking fund terms
and the number of shares constituting any series or the designation of such
series, without any further vote or action by stockholders. The issuance of
preferred stock could adversely affect the voting power of holders of common
stock and the likelihood that such holders will receive dividend payments and
payments upon liquidation and could have the effect of delaying, deferring or
preventing a change in control of Cortelco. We have no present plan to issue
any shares of preferred stock.

Registration Rights

After this offering, the holders of approximately 2,825,682 shares of common
stock will be entitled to rights to require the registration of such shares
under the Securities Act. If we propose to register any of our securities under
the Securities Act, either for our own account or for the account of other
security holders exercising registration rights, such holders are entitled to
notice of such registration and are entitled, subject to certain limitations,
to include their shares to be registered. The holders may also require us to
file a registration statement under the Securities Act with respect to their
shares, and we are required to use our best efforts to effect up to two such
registrations. Furthermore, the holders may require us to register their shares
on Form S-3 when we become eligible to use such form. Generally, we are
required to bear all registration and selling expenses incurred in connection
with any registrations except for underwriting discounts and commissions. These
rights are subject to conditions and limitations, including the right of the
underwriters of an offering to limit the number of shares included in such
registration.

Delaware Anti-Takeover Law and Certain Charter Provisions

We are subject to the provisions of Section 203 of the Delaware General
Corporation Law, an anti-takeover law. In general, the statute prohibits a
publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person became an interested stockholder, unless
the business combination is approved in a prescribed manner. For purposes of
Section 203, a "business combination" includes a merger, asset sale or other
transaction resulting in a financial benefit to the interested stockholder, and
an "interested stockholder" is a person who, together with affiliates and
associates, owns or within three years prior did own, 15% or more of the
corporation's voting stock.

Our certificate of incorporation, effective upon the closing of this offering,
also requires that:

    . the terms of the board of directors will be staggered into three
      classes

    . any action required or permitted to be taken by stockholders of
      Cortelco must be effected at a duly called annual or special meeting
      of the stockholders and may not be effected by written consent

    . the stocholders may amend our bylaws or adopt new bylaws only by the
      affirmative vote of 66 2/3% of the outstanding voting securities

    . special meetings of our stockholders may be called only by the board
      of directors, the Chairman of the Board or the Chief Executive Officer

These provisions may have the effect of delaying, deferring or preventing a
change in control of Cortelco.

Transfer Agent and Registrar

American Securities Transfer and Trust has been appointed as the transfer agent
and registrar for our common stock. Its telephone number is (303) 298-5370.

                        Shares Eligible for Future Sale

Prior to this offering, there has been no market for our common stock. Future
sales of substantial amounts of common stock in the public market could
adversely affect market prices prevailing from time to time. Furthermore, since
only a limited number of shares will be available for sale shortly after this
offering because of contractual and legal restrictions on resale described
below, sales of substantial amounts of common stock in the public market after
the restrictions lapse could adversely affect the prevailing market price and
our ability to raise equity capital in the future.

Upon completion of the offering, we will have 11,374,826 shares of common stock
outstanding, assuming no exercise of the underwriters' over-allotment option
and no exercise of outstanding options and warrants and based upon the number
of shares outstanding as of April 30, 1999. Of these shares, the shares sold in
this offering will be freely tradable without restriction or further
registration under the Securities Act, unless such shares are purchased by our
"affiliates," as that term is defined in Rule 144 under the Securities Act. The
remaining 8,254,826 shares held by existing stockholders, and any shares
purchase by affiliates in this offering, will be "restricted securities" as
that term is defined in Rule 144 under the Securities Act. Our affiliates hold
5,405,369 of the restricted shares. Restricted shares may be sold in the public
market only if registered or if they qualify for an exemption from registration
under Rules 144, 144(k) or 701 under the Securities Act, which are summarized
below.

Upon completion of this offering, the holders of 2,825,682 shares of common
stock, or their transferees, will be entitled to rights to require the
registration of such shares under the Securities Act. Registration of such
shares under the Securities Act would result in such shares becoming freely
tradable without restriction under the Securities Act, except for shares
purchased by our affiliates, immediately upon the effectiveness of such
registration. See "Description of Capital Stock--Registration Rights."

We, our officers, directors and stockholders holding approximately 7,277,419
shares of common stock will agree under written lock-up agreements not to,
without the prior written consent of J.P. Morgan Securities Inc., sell any
shares of common stock for 180 days after the date of this prospectus. See
"Underwriting."

In general, under Rule 144 as currently in effect, beginning 90 days after the
date of this prospectus, stockholders who have beneficially owned restricted
shares for at least one year will be entitled to sell in any three-month period
a number of shares that does not exceed the greater of one percent of the then
outstanding shares of our common stock or the average weekly trading volume of
our common stock in the Nasdaq National Market during the four calendar weeks
immediately preceding the date on which notice of the sale is filed with the
SEC. Sales pursuant to Rule 144 are subject to certain requirements relating to
manner of sale, notice and availability of current public information about
Cortelco. A person, or person whose shares may be aggregated, who is not deemed
to have been one of our affiliates at any time during the 90 days immediately
preceding the sale and who has beneficially owned restricted shares for at
least two years is entitled to sell such shares pursuant to Rule 144(k) without
regard to the limitations described above.

Any of our employees, directors or consultants who purchased, or was awarded
shares or options to purchase shares pursuant to a written compensatory plan or
contract is entitled to rely on the resale provisions of Rule 701 under the
Securities Act, which permits stockholders to sell their Rule 701 shares
without having to comply with Rule 144's holding period restrictions, in each
case commencing 90 days after the date of this prospectus. In addition, holders
who are not affiliates may sell Rule 701 shares without complying with the
public information, volume and notice provisions of Rule 144.

We intend to file a registration statement under the Securities Act covering
shares of common stock reserved for issuance under our Stock Incentive Plans
and the Purchase Plan. Based on the number of options outstanding and options
and shares reserved for issuance at April 30, 1999, such registration statement
will cover approximately 2,677,784 shares. Such registration statement is
expected to be filed and to become effective as soon as practicable after the
date of this prospectus. Shares registered under such registration statement
will, subject to Rule 144 volume limitations applicable to affiliates, be
available for sale in the open market, unless such shares are subject to
vesting restrictions with Cortelco or the lock-up agreements described above.

The underwriters are offering the common stock subject to their acceptance of
the common stock and subject to prior sale. The underwriting agreement provides
that the obligations of the underwriters to purchase shares of common stock are
subject to the approval of certain legal matters by counsel and to certain
other conditions. If any of the shares of common stock are purchased by the
underwriters pursuant to the underwriting agreement, all of the shares, other
than the shares of common stock covered by the over-allotment option described
below, must be purchased.

The underwriters propose to offer the shares of common stock directly to the
public at the public offering price set forth on the cover page of this
prospectus and to dealers at such price less a concession not in excess of $
per share. The underwriters may allow, and such dealers may reallow, a
concession not in excess of $    per share to other dealers. After the initial
public offering of the common stock, the offering price and other selling terms
may be changed from time to time by the underwriters.

We and certain selling stockholders have granted to the underwriters an option
to purchase up to 468,000 additional shares of common stock on the same terms
and conditions solely to cover over-allotments. We have agreed to sell up to
37,288 additional shares and the selling stockholders have agreed to sell up to
430,712 additional shares. The option may be exercised during the 30-day period
after the date of this prospectus. If the underwriters' option is exercised in
full, the total price to public would be $   , the total underwriting discounts
and commissions would be $   , and total proceeds to us would be $   , before
deducting $    in expenses.

We and the selling stockholders have agreed to indemnify the underwriters
against specified liabilities, including liabilities under the Securities Act,
and to contribute to payments that the underwriters may be required to make in
connection with such liabilities.

We, our officers, directors and stockholders holding an aggregate of 7,277,419
shares of common stock will agree not to, without the prior written consent of
J.P. Morgan Securities Inc., (1) offer, pledge, announce the intention to sell,
sell, contract to sell, sell any option or contract to purchase, purchase any
option or contract to sell, grant any option, right or warrant to purchase or
otherwise transfer or dispose of, directly or indirectly, any shares of common
stock or any securities of Cortelco which are substantially similar to the
common stock, including but not limited to any securities that are convertible
into or exercisable or exchangeable for, or that represent the right to receive
common stock or any such substantially similar securities or (2) enter into any
swap, option, future, forward or other agreement that transfers, in whole or in
part, any of the economic consequences of ownership of common stock or any
securities

                                       56

substantially similar to the common stock. We may, however, issue shares of
common stock upon the exercise of stock options that are currently outstanding,
and may grant additional options under our stock option plans, provided that,
without the prior written consent of J.P. Morgan Securities Inc., such
additional options shall not be exercisable during such period.

In connection with the offering, the underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the common stock.
Specifically, the underwriters may over-allot the offering, creating a
syndicate short position. In addition, the underwriters may bid for, and
purchase, shares of common stock in the open market to cover syndicate short
positions or to stabilize the price of the common stock. Finally, the
underwriting syndicate may reclaim selling concession allowed for distributing
the common stock in the offering, if the syndicate repurchases previously
distributed common stock in syndicate covering transactions, in stabilization
transactions or otherwise. Any of these activities may stabilize or maintain
the market price of the common stock above independent market levels. The
underwriters are not required to engage in these activities, and may end any of
these activities at any time.

Prior to this offering, there has been no public market for our common stock.
The initial public offering price for the shares of common stock offered in
this offering will be determined by negotiation among Cortelco, the selling
stockholders and the underwriters. Among the factors to be considered in
determining the initial public offering price are our revenue and earnings,
market valuations of other companies engaged in activities similar to ours,
estimates of our business potential and prospects, the present state of our
business operations, our management, the general condition of the securities
markets at the time of the offering and other factors deemed relevant. The
estimated initial public offering price range set forth on the cover of this
preliminary prospectus is subject to change as a result of market conditions
and other factors. There can be no assurance that an active trading market will
develop for our common stock or that our common stock will trade in the public
market at or above the initial public offering price.

                          Independent Auditors' Report

To the Board of Directors and Stockholders of Cortelco Systems, Inc.

We have audited the accompanying consolidated balance sheets of Cortelco
Systems, Inc. and subsidiaries (the "Company"), a 97% owned subsidiary of
Cortelco Systems Holding Corporation, as of July 31, 1997 and 1998 and the
related consolidated statements of operations, cash flows, and stockholders'
equity (deficit) for each of the three years in the period ended July 31, 1998.
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 did not audit the statements of operations and cash flows of
Cortelco Puerto Rico, Inc. (a consolidated subsidiary) for the year ended July
31, 1996, which statements reflect total revenues constituting 39.7% of the
related consolidated total for that year. Those statements were audited by
other auditors whose report has been furnished to us and our opinion, insofar
as it relates to the amounts included for Cortelco Puerto Rico, Inc. for the
year ended July 31 1996, is based solely on the report of such other auditors.

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
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, based on our audits and the report of other auditors, such
consolidated financial statements present fairly, in all material respects, the
financial position of Cortelco Systems, Inc. and its subsidiaries at July 31,
1997 and 1998 and the results of their operations and their cash flows for each
of the three years in the period ended July 31, 1998 in conformity with
generally accepted accounting principles.

audited the financial statements of Cortelco Puerto Rico, Inc. for any period
subsequent to July 31, 1996.

                   Notes to Consolidated Financial Statements
                    Years Ended July 31, 1996, 1997 and 1998

1. Description of Business and Organization

Description of Business--Cortelco Systems, Inc. (the "Company" or "CSI")
designs, develops and markets integrated enterprise communications systems for
routing and controlling the voice, video and data communications of businesses
and other organizations. In addition to selling Millennium systems and related
systems products, Cortelco also resells cellular airtime, cellular telephones
and third-party voice communications systems in Puerto Rico.

Organization--Effective July 31, 1993, the telecommunications business of CMC
Industries, Inc. ("CMC") was spun-off to Cortelco Systems Holding Corporation
("CSHC", the parent company). From August 1, 1993 to July 31, 1995, CSHC
combined the operations of the Company (the "Systems" and "Automatic Call
Distributor" product lines) with the operations related to another product
line, single line telephones, and accounted for these product lines as a single
business unit.

Effective August 1, 1995, CSHC contributed the assets of the "Systems" and
"Automatic Call Distributor" product lines to the Company. The assets were
recorded at historical book value.

2. Basis of Presentation

Basis of Presentation--The Company was a 97% owned subsidiary of CSHC through
April 1999. The consolidated financial statements of CSI include the accounts
of its wholly-owned subsidiaries, Cortelco Puerto Rico, Inc. for all periods
presented and Cortelco, Inc. (the "Automatic Call Distributor" product line)
through March 31, 1997, at which time Cortelco, Inc. was spun-off to CSHC (see
Note 4). The consolidated financial statements also include the accounts of its
55% owned joint venture in mainland China since the date of acquisition (see
Note 9). Minority interest is recognized for the remaining 45% interest in the
financial position and operations of the joint venture. All significant
intercompany balances have been eliminated.

The Company is also affiliated with the following entities through common
stockholder ownership:

  Cortelco International, Inc. ("CII", subsidiary of CSHC)
  Cortelco Puerto Rico, Inc. ("CPR", subsidiary of CSHC)
  Cortelco Canada ("CC", subsidiary of CSHC)
  BCS Technologies, Inc.
  CMC Industries, Inc.

The Company also has two inactive subsidiaries, Cortelco Holding Corp. and CTC
Holding Corp.

In April 1999 a series of transactions occurred whereby CSHC distributed the
common stock of the Company to the CSHC stockholders and CPR formed a new
wholly-owned subsidiary in the Commonwealth of Puerto Rico, Cortelco Systems
Puerto Rico, Inc. ("CSPR"), in contemplation of a merger between the Company
and the newly formed subsidiary. Previous to the merger, CPR contributed
substantially all of the operations and certain assets and liabilities to the
newly formed CSPR. Cortelco Puerto Rico, Inc. retained certain real estate
assets and the related mortgage note payable. On April 8, 1999, CPR transferred
all issued and outstanding stock of CSPR to CSHC, the Company issued 553,880
shares of common stock to CSHC in exchange for an 100% interest in CSPR and
CSPR assumed the CPR Credit Facility described in Note 11. As the business
combination was between entities under common control, the merger has been
accounted for in a manner similar to a pooling of interests and accordingly,
all periods presented in the accompanying financial statements reflect the
results of operations on an "as if pooled" basis. The common stock issued to
effect the business combination has been reflected as outstanding for all
periods presented.

3. Summary of Significant Accounting Policies

Cash and Cash Equivalents--All highly liquid investments with a maturity of
three months or less are considered to be cash equivalents.


                                      F-8
<PAGE>

                    Cortelco Systems, Inc. and Subsidiaries

            Notes to Consolidated Financial Statements--(Continued)
                    Years Ended July 31, 1996, 1997 and 1998

The Company provides a centralized cash management function whereby all cash
receipts on customer accounts are processed through a lockbox arrangement and
swept daily to paydown the line of credit agreement discussed in Note 11. All
cash disbursements are handled through daily draws on the line of credit to
cover the Company's outstanding checks.

Inventories--Inventories are valued at the lower of cost or market. Cost is
determined by the last-in, first-out ("LIFO") method for approximately 81% and
72% of the inventories at July 31, 1997 and 1998, respectively. The first-in,
first-out ("FIFO") method is principally used for the remainder.

Property and Equipment--Property and equipment are stated at cost. Depreciation
is provided using the straight-line method for financial reporting purposes and
accelerated method for income tax reporting purposes over the estimated useful
lives of the assets, generally five to thirty years.

Investments--Investments in affiliates and corporate joint ventures which
represent a 20% to 50% equity interest are accounted for under the equity
method. Investments representing less than a 20% interest are carried at the
lower of cost or net realizable value.

Intangible Assets--Intangible assets primarily represent costs incurred to
acquire and/or establish patents, trademarks and software technology. These
costs are being amortized on a straight-line basis over the estimated useful
lives of the assets, generally five years. The amortization period begins with
the initial introduction of the underlying product to the market in order to
properly match revenue and expense. The Company reviews the carrying value of
intangible assets for impairment based on undiscounted cash flows whenever
events or changes in circumstances occur which might indicate that the carrying
amount might not be recoverable.

Deferred Financing Costs--Deferred financing costs represent costs associated
with the issuance of debt. These costs are being amortized using the effective
interest method over the life of the related debt issue.

Product Warranties--The Company provides the customer with a warranty from the
date of purchase. Estimated warranty obligations are recorded based on actual
claims experience.

Income Taxes--Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes. The
Company's results are included in the consolidated U.S. income tax return of
Cortelco Systems Holding Corporation. Income taxes are not provided on the
unremitted earnings of the Company's foreign subsidiaries and foreign joint
ventures since it is the Company's intention to continue to reinvest these
earnings.

Revenue Recognition--Revenues are recognized at the time products are shipped
or when title passes. Net sales is comprised of sales reduced by related sales
allowances. Revenues from cellular airtime are recognized when earned based on
cellular airtime contracts. The Company receives sales commissions on certain
transactions with the Puerto Rico Telephone Company. These commissions are
recorded as cellular airtime in the accompanying financial statements.

Cellular Telephone Equipment Deferred Acquisition Costs--The Company offers
commissions to dealers, and discounts to customers, on the sale of cellular
telephone equipment that is part of a simultaneous leasing of cellular
telephone service. These commissions and discounts are deferred and amortized
to income over the life of each contract, which usually ranges from one to
three years.

Allocation of Certain Shared Expenses--The accompanying financial statements
include the assets, liabilities, revenues and expenses specifically
identifiable with the Company as well as certain allocated expenses for
services provided by CSHC and CII. The costs have been allocated using formulas
including estimates of effort expended and sales and management believes the
allocation method to be reasonable. The financial statements may not
necessarily reflect the assets and liabilities and results of operations of the
Company had it been operated as a stand-alone entity. Management estimates that
the costs that would have been incurred on a stand alone basis would have
approximated $120,000, $390,000, and $100,000 for the years ended July 31,
1996, 1997, and 1998.

Medical Care and Disability Benefit Plans--The Company is self-insured with
respect to certain medical and disability benefits offered to substantially all
employees through participation in an insurance plan with an affiliated
company. These

                    Years Ended July 31, 1996, 1997 and 1998

costs are charged against earnings in the period in which claims are incurred.
The Company does not provide benefits to retired employees.

Foreign Currency Translation--The assets and liabilities of the foreign joint
venture are translated at current exchange rates with the related translation
adjustments reported as a separate component of stockholders equity. Income
statement accounts are translated at the average exchange rate during the
period.

Earnings Per Share--The Company follows Statement of Financial Accounting
Standard ("SFAS") No. 128, "Earnings Per Share," which requires disclosure of
basic and diluted earnings per share ("EPS"). Basic EPS is computed by dividing
income available to common stockholders by the weighted average number of
common shares outstanding during the year. Diluted EPS is similar to basic EPS
except that the weighted average number of common shares outstanding is
increased to include the number of additional common shares that would have
been outstanding if the potentially dilutive common shares, such as options,
had been issued.

Reverse Stock Split--On February 24, 1999, the Company's board of directors
authorized a 1 for 10 reverse stock split of its common and preferred stock
effective for stockholders of record on March 1, 1999. The Company's board of
directors also approved an amendment to the Company's certificate of
incorporation to decrease the authorized common and preferred shares to
50,000,000 and 10,000,000, respectively, and to increase the par value per
common share from $.0001 to $.001. Shares outstanding and all per share amounts
in the accompanying financial statements have been restated to give effect to
the reverse stock split.

Fair Value of Financial Instruments--The carrying amounts of financial
instruments such as cash, accounts receivable, accounts payable and the
outstanding borrowings under the revolving credit agreement approximate their
fair value due to the short term nature of the instruments. Additionally, the
carrying value of the Company's investment in the foreign joint venture
discussed in Note 9 approximates fair value. As determined by an independent
third-party, the fair value of the Company's subordinated convertible debt
could not be practicably determined due to the lack of a quoted market and the
complex features of the security. Additional information pertinent to the debt
agreement is contained in Note 11.

Estimates--The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

Reclassifications--Certain amounts in the 1997 financial statements have been
reclassified to conform with the 1998 presentation.

New Accounting Standards--In June 1997, the Financial Accounting Standards
Board ("FASB") issued SFAS 130, "Reporting Comprehensive Income," which
established standards for reporting and display of comprehensive income and its
components and requires a separate statement to report the components of
comprehensive income for each period reported. The provisions of this statement
are effective for fiscal years beginning after December 15, 1997. Management
believes this statement may require expanded disclosure in the Company's
financial statements.

In June 1998, FASB issued SFAS 133, "Accounting for Derivative Instruments and
Hedging," which established accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. The provisions of this statement are
effective for fiscal years beginning after June 15, 1999. Management has not
evaluated what impact, if any, the adoption of this statement will have on the
disclosures in the Company's financial statements.

4. Discontinued Operations

Effective March 31, 1997 the Company distributed all of the outstanding common
stock of its subsidiary in the automatic call distribution business to the CSHC
stockholders. The net assets, results of operations and cash flows of Cortelco,
Inc. have been reported as discontinued operations in the accompanying
financial statements. Summarized financial information of the discontinued
operations is presented as follows:

As of the date of the spin-off, the net assets of the Company's subsidiary in
the automatic call distributor business totalled $1,250,000 and this amount was
charged against retained earnings in the accompanying 1997 balance sheet to
reflect the distribution of the subsidiary's stock.

5. Major Customers and Concentrations of Credit Risk

Financial instruments which potentially subject the Company to a concentration
of credit risk consist principally of cash, trade accounts receivable and notes
receivable. The Company maintains its cash balances with large regional or
national financial institutions and has not experienced losses. The Company's
products are sold principally to dealers, value added resellers, national
accounts and the U.S. government. Approximately 38% of the Company's revenues
are generated within the Commonwealth of Puerto Rico. The Company's credit risk
is limited principally to trade accounts receivable. The Company performs
ongoing credit evaluations of its customers and generally does not require
collateral. No additional risk beyond amounts provided for collection losses is
believed inherent in the Company's trade accounts receivable.

6. Inventories

Inventories consist of the following:

</TABLE>

In 1997, the liquidation of LIFO inventories decreased cost of revenues and
therefore decreased the net loss from continuing operations before taxes by
$200,000. In 1998, the liquidation of LIFO inventories decreased cost of
revenues and therefore decreased the net loss from continuing operations before
taxes by $84,000.

9. Investment in Joint Ventures

The Company has a $67,000 investment representing a 10% equity interest in a
Poland-based company (DTS/ZWUT) which will manufacture, sell and distribute
products designed and marketed by the Company. The Company accounts for its
interest in the joint venture at the lower of cost or net realizable value.

During 1996, the Company entered into an acquisition agreement with a Taiwanese

11. Debt

Cortelco Systems, Inc. Revolving Credit Facility--On July 31, 1997, CSI entered
into a new loan and security agreement with Foothill Capital (the "CSI Credit
Facility") which provides for borrowings based upon an asset formula involving
eligible accounts receivable and inventories, up to a maximum of $7,500,000,
including letters of credit, and expires in July 2001. At July 31, 1998, CSI
had outstanding borrowings under this facility of $2,353,000. The Company had
no outstanding letters of credit at July 31, 1998. The borrowings are
collateralized by substantially all the assets of the Company. The CSI Credit
Facility provides for interest at the reference rate plus the margin in effect,
which fluctuates during the term of the CSI Credit Facility, based on the
Company's satisfaction of certain minimum income requirements. At July 31, 1998
the effective interest rate was 8.875% (prime rate of 8.5% plus a margin of
0.375%). The CSI Credit Facility also provides for an annual facility fee equal
to 0.125% of the maximum borrowing base and an annual unused line fee equal to
0.375% based upon the average unused portion of the available credit.

The CSI Credit Facility also contains covenants which, among other matters,
limit the ability of the Company to incur indebtedness; merge, consolidate or
acquire or sell assets; pay dividends; or redeem or exchange capital stock. At
July 31, 1998 the Company was not in compliance with certain covenants
contained in the CSI Credit Facility. On March 30, 1999, the Company received a
waiver related to the covenants previously in default. On April 8, 1999, the
CSI Credit Facility was amended to pledge the outstanding common stock of CSPR.

Cortelco Puerto Rico, Inc. ("CPR") Revolving Credit Facility--On August 29,
1997, CPR entered into a new revolving line of credit agreement with Foothill
Capital (the "CPR Credit Facility") under which CPR may borrow up to
$1,500,000. The agreement provides for interest at a variable rate plus 1.25%
(9.75% at July 31, 1998). The CPR Credit Facility contains various restrictive
covenants and is secured by liens on accounts receivable and inventories as
well as a pledge of CPR's stock. At July 31, 1998, CPR had outstanding
borrowings under this facility of $386,000.

The CPR Credit Facility contains covenants which, among other matters limit the
ability of CPR to incur indebtedness; merge, consolidate or acquire or sell
assets; pay dividends; or redeem or exchange capital stock. At July 31, 1998,
CPR was not in compliance with certain covenants contained in the CPR Credit
Facility. On March 30, 1999, CPR received a waiver related to the covenants
previously in default.

On April 8, 1999, in connection with the assumption of the CPR Credit Facility
by CSPR (see Note 2), the CPR Credit Facility was amended to include as an
event of default a failure by CSHC to pledge the outstanding stock of CII to
the lender on or before May 28, 1999, as contemplated by CII's credit facility
with the lender.

(1) The outstanding balance of $3,000,000 represents borrowings under a
    subordinated note agreement dated July 31, 1997 with ChinaVest IV, L.P. The
    note matures on July 31, 2002 and is convertible into shares of the
    Company's Series A Convertible Preferred Stock based on a conversion price
    determined by a formula defined in the agreement, which is based on the
    Company's audited net income for the fiscal year ended July 31, 1998. Based
    on the conversion price formula, the holder can convert $686,000 of
    principal to 1,463,206 shares of Series A Convertible Preferred Stock. The
    holder has the option to convert the note at any time subsequent to July
    31, 1998. The agreement provides for interest at the rate of 8% annually.
    Upon conversion, the accrued interest on the principal amount converted by
    the holder is payable within sixty days following the date of conversion.
    The Company's Series A Convertible Preferred Stock has full voting rights
    and is convertible into common shares at any time.
  The agreement also contains covenants which, among other matters, limit the
  ability of the Company to merge, consolidate, acquire, or sell assets. At
  July 31, 1998, the Company was not in compliance with a covenant contained
  in the agreement. On April 5, 1999, the Company received a waiver related
  to the covenant previously in default. Additionally on April 5, 1999, the
  holder of the subordinated note provided their consent to a series of
  transactions, including the merger with CSPR and the reverse stock split
  discussed in Note 1 and the repurchase of common stock from CSHC in partial
  settlement of the outstanding note receivable (see Note 15).

(2) The outstanding balance at July 31, 1997 represents borrowings by CPR under
    a term loan agreement bearing interest at an annual rate of 9.85%. On
    August 29, 1997, the agreement was refinanced. The new agreement bears
    interest at a fixed rate of 10% and is due in monthly installments of
    principal and interest totalling $28,170 through September 1, 2002.
    Subsequent to September 1, 2002, the remaining principal balance will be
    negotiated for a period of five additional years. The agreement is
    collateralized by certain property. The fair value of the term loan was
    estimated by discounting future cash flows using rates currently available
    for debt with similar terms and remaining maturities. The fair value was
    estimated to be $3,318,000 at July 31, 1998.

The scheduled repayment of long-term debt is as follows:

warehouse space.

13. Income Taxes

The Company's current taxable income has historically been included in the
consolidated income tax return of CSHC. There does not currently exist a tax
sharing agreement for allocating income taxes. The consolidated provision or
benefit is allocated proportionately between the subsidiaries of CSHC based on
the contribution of each company in the consolidated federal tax return as if
each company calculated its tax on a separate return basis.

The financial statements of the Company do not include a provision (benefit)
for income taxes for 1997 and 1998 due to cumulative net operating losses.

The components of income tax expense attributable to continuing operations for
1996 are as follows:

Income taxes are not provided for the undistributed earnings of the foreign
joint venture as such earnings are intended to be permanently reinvested. Such
earnings would become taxable upon the sale or liquidation or upon the
remittance of dividends. Accumulated undistributed earnings on which U.S. taxes

stock options are granted only to employees and are issued at prices not less
than 100% of the fair market value of the stock at the date of grant. The

greater than ten years from the date of grant. Stock bonuses and restricted
stock purchase agreements are granted only to directors, officers, or employees
of or consultants to the Company and are issued at prices not less than 85% of
the fair market value of the stock at the date of grant. During 1998, 139,311

</TABLE>

The options outstanding at July 31, 1998 are exercisable at prices ranging from
$.70 to $1.00 per share. The weighted average remaining contractual life of all
outstanding options was 9.81 years at July 31, 1998.

The Company accounts for stock-based compensation using the intrinsic value
method prescribed by Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," under which no compensation cost for stock
options is recognized for options granted at or above fair market value. Had
compensation expense been determined based upon fair values at the grant dates
in accordance with SFAS No. 123, "Accounting for Stock-Based Compensation," the
Company's net income and earnings per share would not have been different as
the fair value of the options was determined to be zero on the applicable dates
of grant.

15. Related Parties

As discussed in Note 1, certain expenses reflected in the financial statements
include allocations of expenses from CSHC and CII. These allocations include:

expenses.

During 1997, CSHC incurred certain costs on behalf of CSHC's subsidiaries.
Management of CSHC allocated these costs proportionately among the subsidiaries

legal and accounting matters, etc. As a result, CSI recognized management fee
income of $80,000 for the year ended July 31, 1998. During 1998, CPR received
various administrative services from CSHC and incurred management fee expense
of $265,000 for the year ended July 31, 1998.

18. Commitments and Contingencies

At July 31, 1998 the stock of the Company was pledged as collateral under a
$3,600,000 note payable from CSHC to a corporation. The note matured in
September 1998 and was secured by the outstanding common stock of the Company
and a personal guaranty of the single largest stockholder of CSHC. CSHC did not
make the scheduled payment due in September 1998. On February 25, 1999, CSHC
entered a consent agreement with the corporation whereby the stock of CSI was
released from the original pledge agreement in order to allow the CSI spin-off
discussed in Note 2. Additionally, the corporation agreed not to declare an
event of default. In exchange for the corporation's consent, CSHC remitted
$1,000,000 of the amount outstanding and agreed to a revised repayment
schedule. In connection with the transaction, CSHC's single largest stockholder
loaned CSHC $1,000,000.

The Company is involved in various matters of litigation, claims, and
assessments arising in the ordinary course of business. In the opinion of
management, the eventual disposition of these matters will not have a material
adverse effect on the financial statements.

19. Earnings Per Share

The computations of basic and diluted earnings per share for each year were as
follows:

</TABLE>

Options to purchase 139,311 shares of common stock were outstanding at July 31,
1998 but were not included in the computation of the diluted earnings per share
because the options' exercise price was equal to or greater than the average
market price of the common shares. Additionally, at July 31, 1997 and 1998,
$686,000 of convertible subordinated debt was convertible into 1,463,206 shares
of convertible preferred stock which was convertible into 1,434,894 shares of
common stock. All of these potential common shares were excluded from the
computation of diluted earnings per share for 1997 and 1998 because their
inclusion would have had an antidilutive effect on earnings per share.

20. Subsequent Events

On February 24, 1999, the Company's Board of Directors declared a dividend of
$2,216,514 payable to the stockholders (CSHC and Sea Union) of record on
February 26, 1999. Approximately $1,957,000 of the dividend declared is payable
upon certain events occurring in the future. The remaining amount of the
dividend declaration primarily relates to the distribution of the non-interest
bearing note receivable from an officer/director to CSHC. As the Company has a
retained deficit, the dividend is recorded as a return of capital. The dividend
has been reflected in the financial statements as if declared on July 31, 1998.

On April 5, 1999, the Company's Board of Directors declared a stock dividend of
195,685 shares of the Company's common stock to stockholders of record on April
5, 1999. The dividend was charged to the accumulated deficit in the amount of
$1,956,850, which was based on the fair value of the Company's common stock as
determined by the Board of Directors. The stock dividend has been reflected in
the financial statements as if declared on July 31, 1998.

On April 5, 1999, the Company received 250,000 shares of its common stock from
CSHC in exchange for a $2,500,000 reduction of the outstanding note receivable
balance.

On April 8, 1999, previous to the merger discussed in Note 1, CSPR declared a
dividend of $700,000 payable to the stockholder (CSHC) of record on April 8,
1999, payable upon certain events occurring in the future. The dividend has
been reflected in the financial statements as if declared on July 31, 1998.

Subsequent to year-end, the Company entered into a letter of intent agreement
to merge with an affiliated company, BCS Technologies, Inc.

             Notes to Consolidated Financial Statements (Unaudited)

                 Nine Months Ended April 30, 1998 and 1999

1. Financial Statement Presentation

The accompanying consolidated financial statements have been prepared by the
Company, without audit. It is management's opinion that these statements
include all adjustments, consisting of only normal recurring adjustments,
necessary to present fairly the financial position, results of operations, and
cash flows as of April 30, 1999 and for all periods presented. The results for
the nine months ended April 30, 1998 and 1999 are not necessarily indicative of
the results that may be expected for the full year.

Certain information and footnote disclosures normally included in annual
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted. It is suggested that these
consolidated financial statements be read in conjunction with the consolidated
financial statements and notes thereto as of July 31, 1997 and 1998 and for
each of the three years in the period ended July 31, 1998.

In June 1997, the Financial Accounting Standards Board issued SFAS 130,
"Reporting Comprehensive Income," which established standards of reporting and
display of comprehensive income and its components and requires a separate
statement to report the components of comprehensive income for each period
reported. For the nine months ended April 30, 1998 and 1999 net income (loss)
equaled comprehensive income (loss).

2. Acquisition of BCS Technologies, Inc.

On April 12, 1999, the Company acquired BCS Technologies, Inc. ("BCS") in
exchange for 3,969,680 common shares. The purchase price was determined based
on an independent valuation of the fair value of the BCS equity. The
acquisition was accounted for using the purchase method and the purchase price
of $16,840,000 was preliminarily allocated as follows:

<TABLE>

  Net assets acquired............................................... $  16,840

</TABLE>

The Company has not completed the determination of fair values and the
allocation of purchase price may change. The results of the acquired business
have been included in the consolidated financial statements since the
acquisition date. Goodwill is being amortized on a straight-line basis over
twenty years.

                          Independent Auditors' Report

Board of Directors and Stockholders
BCS Technologies, Inc.
Englewood, Colorado

We have audited the accompanying balance sheets of BCS Technologies, Inc. as of
July 31, 1997 and 1998, and the related statements of operations, changes in
stockholders' equity and cash flows for the eleven months ended July 31, 1997
and the year ended July 31, 1998. These financial statements are the
responsibility of the Corporation'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 audits 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 BCS Technologies, Inc. as of
July 31, 1997 and 1998, and the results of its operations and its cash flows
for the eleven months ended July 31, 1997 and the year ended July 31, 1998 in
conformity with generally accepted accounting principles.

1. Organization

Organization

Organization--BCS Technologies, Inc. is an organization formed by a series of
transactions between the following entities:

  Cortelco Holding Corporation (CHC)

  Cortelco Systems Holding Corporation (CSHC)

  Cortelco, Inc. (CI)

  Cortelco Systems, Inc. (CSI)

  Business Communication Systems, Inc. (BCS)

CHC, CSHC, CI and CSI are all entities related through common stockholder
ownership. BCS was a closely held corporation not related to CHC, CSHC, CI and
CSI. The culmination of the series of transactions was a merger of BCS and CI
with BCS being the accounting acquirer. BCS then changed its name to BCS
Technologies, Inc. (the Company). The stockholders of BCS own 53% of the common
stock of the Company after the merger.

Before the merger of BCS and CI, CI was a wholly-owned subsidiary of CHC, which
was a wholly-owned subsidiary of CSI. CHC had no active operations. CSI was a
wholly-owned subsidiary of CSHC. At the time the merger agreement was signed,
CSHC owned 100% of CSI, which owned 100% of CI. Before the merger agreement was
signed, CSI owned 100% of CHC which owned 100% of CI. On March 27, 1997 CHC was
merged into CI. On April 1, 1997, CI was spun off by CSHC to its stockholders.
Immediately following the spin off of CI, on April 2, 1997, CI was merged into
BCS with BCS as the accounting acquirer. BCS changed its name to BCS
Technologies, Inc.

Description of Business
The Company was originally founded in 1985 and operates from offices in
Englewood, Colorado and a 23,000 square foot facility located in Georgia. The
Company is engaged in the development, sales, manufacturing and distribution of
electronic communication devices throughout the United States.

Business Activities
The Company is a corporation organized under the laws of the State of Delaware
for the purpose of the sale and servicing of electronic communication devices
throughout the United States.

2. Summary of Significant Accounting Policies

Use of Estimates in Preparing Financial Statements
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Cash and Cash Equivalents
For purposes of the statement of cash flows, the Company considers all highly
liquid investments purchased with a maturity of three months or less to be cash
equivalents. Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of cash and temporary cash
investments. At times, cash balances held at financial institutions were in
excess of FDIC insurance limits. The Company limits the amount of credit
exposure to any one financial institution. The Company believes no significant
concentration of credit risk exists with respect to these cash investments.

Revenue Recognition

The Company recognizes revenues from system and product sales when title passes
to the customer. Revenues from prepaid maintenance contracts are recognized
ratably over the terms of the contracts. Revenues from the sales of systems
accounted for approximately 32%, 53%, 38%, and 78% for the eleven months ended
July 31, 1997, the year ended July 31, 1998, and the nine months ended April
30, 1998 and the period August 1, 1998 through April 12, 1999. The Company
generates the remainder of its revenue from parts sales and system maintenance.

Accounts Receivable
The Company charges off all known uncollectible accounts on a current basis. No
reserve for uncollectible accounts is required, as any accounts which are
considered doubtful are not considered material to the financial statements.


                                      F-32
<PAGE>

                             BCS Technologies, Inc.

                   Notes to Financial Statements--(Continued)

Inventories
The Company uses the lower of first-in, first-out ("FIFO") cost or market in
valuing inventories.

Depreciation
The Company provides for depreciation of property and equipment using straight-
line and accelerated methods for financial and income tax reporting purposes
over the estimated useful lives of the assets, which is generally fifteen years
for leasehold improvements, five years for machinery and equipment, five to
seven years for furniture and fixtures and vehicles and three years for
computer software.

Product Warranties
The Company provides the customer with a warranty from the date of purchase.
Estimated warranty obligations are recorded based on actual claims experience.

Income Taxes
Income tax expense is based on reported income before income taxes. Deferred
income taxes reflect the temporary difference between assets and liabilities
recognized for financial reporting and such amounts recognized for tax purposes
which requires recognition of deferred income tax assets and liabilities.
Deferred income tax assets and liabilities are determined based on the
differences between the financial statement and tax basis of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. A valuation allowance is recognized if it
is anticipated that some or all of a deferred income tax asset may not be
realized.

Advertising

Advertising costs are charged to operations in the year incurred. The Company
expended $170,426 for the eleven months ended July 31, 1997, $117,912 for the
year ended July 31, 1998, and $91,077 for the nine months ended April 30, 1998
and $97,271 for the period August 1, 1998 through April 12, 1999.

Interim Financial Statements

The financial statements for the six months ended April 30, 1998 and the period
August 1, 1998 through April 12, 1999 are unaudited, but in the opinion of
management, include all adjustments necessary to fairly state the results
therein, such adjustments being of a normal, recurring nature. Operating
results for the period August 1, 1998 through April 12, 1999 are not
necessarily indicative of the results that may be expected for the fiscal year
ending July 31, 1999. All April 30, 1998 and April 12, 1999 data presented in
these footnotes is unaudited.

Stock Option Plans
The Company utilizes Statement of Financial Accounting Standards No. 123 (FAS
123), "Accounting for Stock-Based Compensation". The Statement defines a fair
value based method of accounting for stock options or similar equity
instrument. FAS 123 allows an entity to continue to measure compensation cost
for employee stock option plans using the intrinsic value based method of
accounting prescribed by Accounting Principles Board Opinion (APB) No. 25,
which was elected by the Company. Accordingly, the Company must make certain
pro forma disclosures as if the fair value based method had been applied.

Earnings (Loss) Per Common Share
Basic earnings per share is computed by dividing income available to common
stockholders by the weighted-average number of common shares outstanding for
the period. Dilutive earnings per share reflects the potential dilution that
could occur if dilutive securities, stock options, were exercised.

3. Business Acquisition

On April 2, 1997, the Company acquired the net assets of Cortelco, Inc., which
had a fair value of $1,750,000, in exchange for 10,675,850 shares of common
stock. The acquisition was accounted for as a reverse acquisition using the
purchase method of accounting, and the results of CI's operations were included
in the Company's financial statements from the date of acquisition.

The Company acquired cash of $500,000, accounts receivable of $509,523,
inventory of $1,054,028, prepaid expenses of $70,185, property and equipment of
$183,333, and current liabilities of $567,069 in the purchase of Cortelco, Inc.

The following unaudited pro forma information presents the results of

Additional Stock Plan Information.
Since the Company continues to account for its stock-based awards to employees
using the intrinsic value method in accordance with APB No. 25, FAS 123,
"Accounting for Stock-Based Compensation," requires the disclosure of pro forma
net income (loss) and earnings (loss) per share had the Company adopted the
fair value method as of the beginning of 1995. Under FAS 123, the fair value of
stock-based awards to employees is calculated through the use of option pricing
models, even though such models were developed to estimate the fair value of
freely tradable, fully transferable options

                                      F-36

                   Notes to Financial Statements--(Continued)

without vesting restrictions, which significantly differ from the Company's
stock option awards. These models also require subjective assumptions,
including future stock price volatility and expected time to exercise, which
greatly affect the calculated values. The Company's fair value calculations on
stock-based awards under the stock plans were made using the Black-Scholes
option pricing model with the following weighted average assumptions: expected
life, 8 years from the date of grant in 1997 and 10 years from the date of
grant in 1999; stock volatility, 0% in 1997 and in 1999; risk-free interest
rate, 6.75% in 1997 and 5.0% in 1999 and no dividends during the expected term.
The Company's calculations are based on a single option award valuation
approach, and forfeitures are recognized as they occur. If the computed fair
values of the 1997 and 1999 awards had been amortized to expense over the
vesting period of the awards, the effect on pro forma net income (loss) would
have been insignificant.

Prior to April 2, 1997, the Company had elected under Subchapter S of the
Internal Revenue Code to have its income taxed directly to its stockholders.
The 1997 provision for income taxes includes only the taxable income from April
2, 1997 through July 31, 1997. Pro forma net income and earnings per share have
been determined assuming the Company had been taxed under Subchapter C of the
Internal Revenue Code for federal and state purposes for 1997.

                   Notes to Financial Statements--(Continued)

As a result of the merger, the Company has a net operating loss carryforward of
approximately $8,250,000 available to offset Georgia state income taxes. The
financial statements and disclosures do not include recognition of
approximately $495,000 of deferred income tax benefit due to the significant
uncertainty of its future realization.

12. Earnings (Loss) Per Common Share

Outstanding stock options to purchase 1,383,542, 1,364,750, 1,364,750 and
1,489,750 shares of common stock were not included in the computation of
diluted earnings (loss) per common share for the eleven months ended July 31,
1997, the year ended July 31, 1998, and the nine months ended April 30, 1998
and the period August 1, 1998 through April 12, 1999. The effect of including
the stock options would be antidilutive or the stock options were exercisable
from shares owned by existing stockholders.

A summary of the diluted weighted average number of common shares is as
follows:

             Unaudited Pro Forma Consolidated Financial Information

The following pro forma consolidated statements of operations data for the year
ended July 31, 1998 and the nine month periods ended April 30, 1998 and 1999
represent the unaudited pro forma operating results as if the acquisition of
BCS Technologies, Inc. had occurred as of August 1, 1997. The following pro
forma consolidated balance sheet data presents the unaudited pro forma
financial condition of the Company as if the acquisition of BCS Technologies,
Inc. had occurred as of April 30, 1999. The pro forma financial data reflects
adjustments to the historical financial statements of Cortelco and BCS
Technologies, Inc., that (1) reflect the purchase method of accounting for the
acquisition of BCS, and (2) eliminate the results of operations and related
assets and liabilities not acquired from the merger with Cortelco Systems
Puerto Rico.

The historical consolidated balance sheet at April 30, 1999 reflects the
acquisition of BCS and the merger with Cortelco Systems Puerto Rico in April
1999, therefore only pro forma offering adjustments are required to be
presented.

The pro forma, as adjusted, financial information gives effect, additionally,
to (1) the conversion of convertible preferred stock into 1,434,894 shares of
common stock upon the closing of this offering, and (2) this offering and the
uses of proceeds from this offering.

The pro forma financial data does not purport to represent what the company's
financial position or results of operations actually would have been had the
transactions occurred on the dates indicated, or to project the company's
financial position or results of operations at any future date or for any
future period. The following pro forma financial data should be read in
conjunction with the Company's consolidated financial statements and related
notes, BCS Technologies' financial statements and related notes and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" which is included elsewhere.

       Notes to Pro Forma Consolidated Financial Information (Unaudited)

1. Basis of Presentation

The pro forma consolidated statements of operations data for the year ended
July 31, 1998 and the nine month periods ended April 30, 1998 and 1999
represent the unaudited pro forma operating results as if the acquisition of
BCS Technologies, Inc. ("BCS") had occurred as of August 1, 1997. The pro forma
financial data reflects adjustments to the historical financial statements of
Cortelco Systems ("the Company") and BCS, that (1) reflect the purchase method
of accounting for the acquisition of BCS, and (2) eliminate the results of
operations and related assets and liabilities not acquired from the merger with
Cortelco Systems Puerto Rico.

The historical consolidated balance at April 30, 1999 reflects the acquisition
of BCS and the merger with Cortelco Systems Puerto Rico in April 1999,
therefore only pro forma offering adjustments are required to be presented.

The pro forma, as adjusted, financial information gives effect, additionally,
to (1) the conversion of convertible preferred stock debt into 1,434,894 shares
of common stock upon the closing of the offering, and (2) the offering and the
uses of proceeds thereof.

The pro forma financial data does not purport to represent what the Company's
financial position or results of operations actually would have been had the
transactions occurred on the dates indicated, or to project the Company's
financial position or results of operations at any future date or for any
future period. The following pro forma financial data should be read in
conjunction with Cortelco's consolidated financial statements and related
notes, BCS' financial statements and related notes and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" which is
included elsewhere.

2. Pro Forma Adjustments

(a) To reflect the elimination of revenues and cost of revenues and balances
between Cortelco Systems, Inc. and BCS.

(b) To reflect the elimination of rental income related to the building
retained by Cortelco Puerto Rico, Inc. and not acquired by the Company.

(c) To reflect the rental expense to be incurred by the Company in connection
with lease agreement negotiated by Cortelco Puerto Rico, Inc. for building
space.

(d) To reflect the goodwill amortization related to the BCS acquisition,
goodwill is amortized over a 20 year life, resulting in annual amortization of
$565,000 and nine month amortization of $424,000.

(e) To reflect the elimination of the depreciation for building improvements
not acquired from Cortelco Puerto Rico, Inc.

(f) To reflect the elimination of interest expense and amortization of deferred
financing costs related to the mortgage payable not assumed from Cortelco
Puerto Rico, Inc. Interest expense totaled $283,000 for the year ended July 31,
1998 and $206,000 and $230,000 for the nine months ended April 30, 1998 and
1999, respectively. The amortization of deferred financing costs totaled
$44,000 for the year ended July 31, 1998 and $33,000 and $46,000 for the nine
months ended April 30, 1998 and 1999, respectively.

(g) To eliminate income tax expense for the year ended July 31, 1998 as the
Company would have had a consolidated net loss on a pro forma basis.

3. Pro Forma Offering Adjustments

(a) To record the proceeds ($23.2 million) from the issuance of 2,300,000
shares of the Company's common stock, net of $2.1 million underwriting
discounts and commissions and estimated offering expenses, including accounting
and legal fees, filing and listing fees and priority expenses.

(b) To record the repayment of $4.9 million in debt and $0.3 million of related
accrued interest from offering proceeds.

(c) To record the conversion of convertible preferred stock into 1,434,894
common shares.

 Notes to Pro Forma Consolidated Financial Information (Unaudited)--(continued)

(d) To record the decrease in interest expense, including the amortization of
deferred financing costs, resulting from the repayment of the subordinated note
and bank debt and the conversion of debt to common stock.

(e) To record the write-off of deferred financing costs related to the
repayment of $4.9 million of debt on the balance sheet. This expense has been
appropriately excluded from the pro forma consolidated statement of operations
but will be reflected in the Company's historical consolidated financial
statements in 1999 as an extraordinary loss on extinguishment of debt.

(f) To record the income tax effect of the above adjustments at 34%, the
Company's estimated effective tax rate.

Item 14. Indemnification of Officers and Directors.

Under Section 145 of the Delaware General Corporation Law, we have broad powers
to indemnify our directors and officers against liabilities they may incur in
such capacities, including liabilities under the Securities Act.

Our certificate of incorporation provides for the elimination of liability for
monetary damages for breach of the directors' fiduciary duty of care to
Cortelco and its stockholders. These provisions do not eliminate the directors'
duty of care and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available under
Delaware law. In addition, each director will continue to be subject to
liability for breach of the director's duty of loyalty to Cortelco, for acts or
omissions not in good faith or involving intentional misconduct, for knowing
violations of law, for any transaction from which the director derived an
improper personal benefit, and for payment of dividends or approval of stock
repurchases or redemptions that are unlawful under Delaware law. The provision
does not affect a director's responsibilities under any other laws, such as the
federal securities laws or state or federal environmental laws.

We expect to enter into agreements with our directors and officers that require
us to indemnify such persons against expenses, judgments, fines, settlements
and other amounts actually and reasonably incurred (including expenses of a
derivative action) in connection with any proceeding, whether actual or
threatened, to which any such person may be made a party by reason of the fact
that such person is or was a director or officer of Cortelco or any of its
affiliated enterprises, provided such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of Cortelco and, with respect to any criminal proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The
indemnification agreements also set forth certain procedures that will apply in
the event of a claim for indemnification thereunder.

The Underwriting Agreement filed as Exhibit 1.1 to this registration statement
provides for indemnification by the underwriters of Cortelco and its officers
and directors for certain liabilities arising under the Securities Act or
otherwise.

Item 15. Recent Sales of Unregistered Securities.

Since April 1996, we have sold and issued the following unregistered
securities:

(1) In July 1997, we issued a convertible promissory note in the aggregate
    principal amount of $3,000,000 to ChinaVest IV, L.P.

(2) In August 1997, we issued 95,343 shares of common stock to an investor in
    exchange for an interest in the Longhai joint venture.

(3) In April 1999, we issued 3,969,681 shares of common stock to stockholders
    of BCS Technologies, Inc. and assumed options covering 94,279 shares of
    common stock under the BCS 1997 Incentive Plan in connection with the
    acquisition of BCS. We issued 553,880 shares of common stock to Cortelco
    Systems Holding Corporation in connection with the merger with Cortelco
    Systems Puerto Rico.

(4) Since April 1998, we have granted incentive stock options to employees,
    directors and consultants under our 1997 Equity Incentive Plan covering an
    aggregate of 333,505 shares of common stock, at an average exercise price
    of $3.76. No options have been exercised under the 1997 Equity Incentive
    Plan.

(5) Since April 1999, we have granted incentive stock options to employees,
    directors and consultants under our 1999 Equity Incentive Plan covering an
    aggregate of 987,982 shares of common stock, at an average exercise price
    of $9.73. No options have been exercised under the 1999 Equity Incentive
    Plan.

The sales and issuances of securities in the transactions described in
paragraphs (1) through (3) were deemed to be exempt from registration under the
Securities Act by virtue of Section 4(2) and/or Regulation D promulgated under
the Securities Act. The purchasers in each case represented their intention to
acquire the securities for investment only and not with a view to the
distribution thereof. Appropriate legends are affixed to the stock certificates
issued in such transactions. Similar legends were imposed in connection with
any subsequent sales of any such securities. All recipients either received
adequate information about Cortelco or had access, through employment or other
relationships, to such information.

The sales and issuance of securities in the transaction described in paragraphs
(4) and (5) above were deemed to be exempt from registration under the
Securities Act by virtue of Rule 701 promulgated thereunder in that they were
offered and sold either pursuant to written compensatory benefit plans or
pursuant to a written contract relating to compensation, as provided by Rule
701.

Item 17. Undertakings.

We undertake to provide to the underwriters at the closing specified in the
Underwriting Agreement certificates in such denominations and registered in
such names as required by the underwriters to permit prompt delivery to each
purchaser.

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers and controlling persons of Cortelco
pursuant to the foregoing provisions or otherwise, Cortelco has been advised
that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by Cortelco of expenses
incurred or paid by a director, officer or controlling person of Cortelco 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, Cortelco will, unless in the opinion of its counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

We hereby undertake that: (i) for purposes of determining any liability under
the Securities Act, the information omitted from the form of prospectus filed
as part of this registration statement in reliance upon Rule 430A and contained
in a form of prospectus filed by Cortelco 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 the Commission declared it effective, and (ii) for the
purpose of determining any liability under the Securities Act, each post-
effective amendment that contains a form of prospectus shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

the corporation may be called, for any purpose or purposes, by (a) the Chairman

resolution adopted by a majority of the total number of authorized directors
(whether or not there exist any vacancies in previously authorized directorships
at the time any such resolution is presented to the Board for adoption, or (d)
by the holders of shares entitled to cast not less than ten percent (10%) of the
votes at the meeting, and shall be held at such place, on such date, and at such
time as they or he shall fix; provided, however, that following registration of

resolution adopted by a majority of the total number of authorized Directors.

          Section 7.  Notice of Meetings.  Except as otherwise provided by law
                      ------------------
or the Certificate of Incorporation, written notice of each meeting of
stockholders shall be given not less than ten (10) nor more than sixty (60) days
before the date of the meeting to each stockholder entitled to vote at such
meeting, such notice to specify the place, date and hour and purpose or purposes
of the meeting.  Notice of the time, place and purpose of any meeting of
stockholders may be waived, in writing, signed by the person entitled to notice
thereof, either before or after such meeting, and will be waived by any
stockholder by his attendance thereat in person or by proxy, except when the
stockholder attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened.  Any stockholder so waiving notice of such
meeting shall be bound by the proceedings of any such meeting in all respects as
if due notice thereof had been given.  [Del. Code Ann., tit. 8, (S)(S)222, 229]

          Section 8.  Quorum.  At all meetings of stockholders, except where
                      ------
otherwise provided by statute or by the Certificate of Incorporation, or by
these Bylaws, the presence, in person or by proxy duly authorized, of the
holders of a majority of the outstanding shares of stock entitled to vote shall
constitute a quorum for the transaction of business.  Any shares, the voting of
which at said meeting has been enjoined, or which for any reason cannot be
lawfully voted at such meeting, shall not be counted to determine a quorum at
such meeting.  In the absence of a quorum any meeting of stockholders may be
adjourned, from time to time, by vote of the holders of a majority of the shares
represented thereat, but no other business shall be transacted at such meeting.
The stockholders present at a duly called or convened meeting at which a quorum
is present may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum.  Except as
otherwise provided by law, the Certificate of Incorporation or these Bylaws, all
action taken by the holders of a majority of the voting power represented at any
meeting at which a quorum is present shall be valid and binding upon the
corporation; provided, however, that Directors shall be elected by a plurality
of the votes of the shares present in person or represented by proxy at the
meeting and entitled to vote on the election of Directors.  Where a separate
vote by a class or classes is required, a majority of the outstanding shares of
such class or classes, present in person or represented by proxy, shall
constitute a quorum entitled to take action with respect to that vote on that
matter and the affirmative vote of the majority (plurality, in the case of the
election of Directors) of shares of such class or classes present in person or
represented by proxy at the meeting shall be the act of such class.  [Del. Code
Ann., tit. 8, (S)216]

by the vote of a majority of the shares represented thereat.  When a meeting is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place thereof are announced at the meeting at which the
adjournment is taken.  At the adjourned meeting the corporation may transact any
business which might have been transacted at the original meeting.  If the
adjournment is for more than thirty (30) days, or if after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote at the
meeting.  [Del. Code Ann., tit. 8, (S)222 (c)]

          Section 10. Voting Rights.  For the purpose of determining those
                      -------------
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 12 of
these Bylaws, shall be entitled to vote at any meeting of stockholders.  Except
as may be otherwise provided in the Certificate of Incorporation or these
Bylaws, each stockholder shall be entitled to one vote for each share of capital
stock held by such stockholder.  Every person entitled to vote or execute
consents shall have the right to do so either in person or by an agent or agents
authorized by a written proxy executed by such person or his duly authorized
agent, which proxy shall be filed with the Secretary at or before the meeting at
which it is to be used.  An agent so appointed need not be a stockholder.  No
proxy shall be voted after three (3) years from its date of creation unless the
proxy provides for a longer period.  All elections of Directors shall be by
written ballot, unless otherwise provided in the Certificate of Incorporation.

securities having voting power stand of record in the names of two (2) or more
persons, whether fiduciaries, members of a partnership, joint tenants, tenants
in common, tenants by the entirety, or otherwise, or if two (2) or more persons
have the same fiduciary relationship respecting the same shares, unless the
Secretary is given written notice to the contrary and is furnished with a copy
of the instrument or order appointing them or creating the relationship wherein
it is so provided, their acts with respect to voting shall have the following
effect: (a) if only one (1) votes, his act binds all; (b) if more than one (1)
votes, the act of the majority so voting binds all; (c) if more than one (1)
votes, but the vote is evenly split on any particular matter, each faction may
vote the securities in question proportionally, or may apply to the Delaware
Court of Chancery for relief as provided in the General Corporation Law of
Delaware, Section 217(b).  If the instrument filed with the Secretary shows that
any such tenancy is held in unequal interests, a majority or even-split for the
purpose of this subsection (c) shall be a majority or even-split in interest.
[Del. Code Ann., tit. 8, (S)217(b)]

            (b) Persons holding stock in a fiduciary capacity shall be entitled
to vote the shares so held. Persons whose stock is pledged shall be entitled to
vote, unless in the transfer by the pledgor on the books of the corporation he
has expressly empowered the pledgee to vote thereon, in which case only the
pledgee, or his proxy, may represent such stock and vote thereon. [Del. Code
Ann., tit. 8, (S)217(a)]

          Section 12. List of Stockholders.  The Secretary shall prepare and
                      --------------------

list of the stockholders entitled to

<PAGE>

vote at said meeting, arranged in alphabetical order, showing the address of
each stockholder and the number of shares registered in the name of each
stockholder. Such list shall be open to the examination of any stockholder, for
any purpose germane to the meeting, during ordinary business hours, for a period
of at least ten (10) days prior to the meeting, either at a place within the
city where the meeting is to be held, which place shall be specified in the
notice of the meeting, or, if not specified, at the place where the meeting is
to be held. The list shall be produced and kept at the time and place of meeting
during the whole time thereof, and may be inspected by any stockholder who is
present. [Del. Code Ann., tit. 8, (S)219(a)]

          Section 13.  Action without Meeting.  (a) Any action required by
                       ----------------------
statute to be taken at any annual or special meeting of the stockholders, or
any action which may be taken at any Annual or special meeting of the
stockholders, may be taken, without a meeting, without prior notice and
without a vote, if a consent or consents in writing, setting forth the action
so taken, are signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.

        (b) Every written consent shall bear the date of signature of each
stockholder who signs the consent, and no written consent shall be effective
to take the corporate action referred to therein unless, within sixty (60)
days of the earliest dated consent delivered to the Corporation in the manner
herein required, written consents signed by a sufficient number of
stockholders to take action are delivered to the corporation by delivery to
its registered office in the State of Delaware, its principal place of
business or an officer or agent of the corporation having custody of the book
in which proceedings of meetings of stockholders are recorded. Deliver made to
a corporation's registered office shall be by hand or by certified or
registered mail, return receipt requested. [Del. Code Ann., tit. 8, (S)228]

        (c) Prompt notice of the taking of the corporate action without a
meeting by less than unanimous written consent shall be given to those
stockholders who have not consented in writing. If the action which is
consented to is such as would have required the filing of a certificate under
any section of the General Corporation Law of Delaware if such action had been
voted on by stockholders at a meeting thereof, then the certificate filed
under such section shall state, in lieu of any statement required by such
section concerning any vote of stockholders, that written notice and written
consent have been given as provided in Section 228 of the General Corporation
Law of Delaware.

     Section 14.  Organization.  (a) At every meeting of stockholders, the
                  -------------
Chairman of the Board of Directors, or, if a Chairman has not been appointed or
is absent, the President, or, if the President is absent, the most senior Vice
President present, or in the absence of any such officer, a chairman of the
meeting chosen by a majority in interest of the stockholders entitled to vote,
present in person or by proxy, shall act as chairman.  The Secretary, or, in his
absence, an Assistant Secretary directed to do so by the President, shall act as
secretary of the meeting.

        (b) The Board of Directors of the corporation shall be entitled to make
such rules or regulations for the conduct of meetings of stockholders as it
shall deem necessary, appropriate or convenient.  Subject to such rules and
regulations of the Board of Directors, if any, the chairman of the meeting shall
have the right and authority to prescribe such rules, regulations and procedures
and to do all such acts as, in the judgment of such chairman, are necessary,
appropriate or convenient for the proper conduct of the meeting, including,
without limitation, establishing an agenda or order of business for the meeting,
rules and procedures for maintaining order at the meeting and the safety of
those present, limitations on participation in such meeting to stockholders of
record of the corporation and their duly authorized and constituted proxies, and
such other persons as the chairman shall permit, restrictions on entry to the
meeting after the time fixed for the commencement thereof, limitations on the
time allotted to questions or comments by participants and regulation of the
opening and closing of the polls for balloting on matters which are to be voted
on by ballot.  Unless, and to the extent determined by the Board of Directors or
the chairman of the meeting, meetings of stockholders shall not be required to
be held in accordance with rules of parliamentary procedure.

          Section 15.  Number and Term of Office.  The number of Directors which
                       -------------------------
shall constitute the whole of the Board of Directors shall be five (5).  The
number of authorized Directors may be modified from time to time by amendment of
this Section 15 in accordance with the provisions of Section 44 hereof.  Except
as provided in Section 17, the Directors shall be elected by the stockholders at
their annual meeting in each year and shall hold office until the next annual
meeting and until their successors shall be duly elected and qualified.
Directors need not be stockholders unless so required by the Certificate of
Incorporation.  If for any cause the Directors shall not have been elected at an
annual meeting, they may be elected as soon thereafter as convenient at a
special meeting of the stockholders called for that purpose in the manner
provided in these Bylaws.  [Del. Code Ann., tit. 8, (S)(S)141(b), 211(b), (c)]

of Incorporation, vacancies and newly created directorships resulting from any
increase in the authorized number of Directors may be filled by a majority of
the Directors then in office, although less than a quorum, or by a sole
remaining Director, and each Director so elected shall hold office for the
unexpired portion of the term of the Director whose place shall be vacant and
until his successor shall have been duly elected and qualified.  A vacancy in
the Board of Directors shall be deemed to exist under this Section 17 in the
case of the death, removal or resignation of any Director, or if the
stockholders fail at any meeting of stockholders at which Directors are to be
elected (including any meeting referred to in Section 19 below) to elect the
number of Directors then constituting the whole Board of Directors.  [Del. Code
Ann., tit. 8, (S)223(a), (b)]

delivering his written resignation to the Secretary, such resignation to specify
whether it will be effective at a particular time, upon receipt by the Secretary
or at the pleasure of the Board of Directors.  If no such specification is made,
it shall be deemed effective at the pleasure of the Board of Directors.  When
one or more Directors shall resign from the Board of Directors, effective at a
further date, a majority of the Directors then in office, including those who
have so resigned, shall have power to fill such vacancy or vacancies, the vote
thereon to take effect when such resignation or resignations shall become
effective, and each Director so chosen shall hold office for the unexpired
portion of the term of the Director whose place shall be vacated and until his
successor shall have been duly elected and qualified.  [Del. Code Ann., tit. 8,

        Section 42.  Indemnification of Directors, Officers, Employees and
                     -----------------------------------------------------
Other Agents.
- ------------

          (a) Directors and Executive Officers.  The corporation shall indemnify
              --------------------------------
its Directors and executive officers to the fullest extent not prohibited by the
Delaware General Corporation Law; provided, however, that the corporation may
                                  --------  -------
limit the extent of such indemnification by individual contracts with its
Directors and executive officers; and, provided, further, that the corporation
                                       --------  -------
shall not be required to indemnify any Director or executive officer in
connection with any proceeding (or part thereof) initiated by such person or any
proceeding by such person against the corporation or its Directors, officers,
employees or other agents unless (i) such indemnification is expressly required
to be made by law, (ii) the proceeding was authorized by the Board of Directors
of the corporation, or (iii) such indemnification is provided by the
corporation, in its sole discretion, pursuant to the powers vested in the
corporation under the Delaware General Corporation Law.

          (b) Other Officers Employees and Other Agents.  The corporation shall
              -----------------------------------------
have power to indemnify its other officers, employees and other agents as set
forth in the Delaware General Corporation Law.

          (c) Good Faith.  (i) For purposes of any determination under this
              ----------
Bylaw, a Director or executive officer shall be deemed to have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, to have had no reasonable cause to believe that his conduct was
unlawful, if his action is based on information, opinions, reports and
statements, including financial statements and other financial data, in each
case prepared or presented by:

              (A) one or more officers or employees of the corporation whom the
          Director or executive officer believed to be reliable and competent in
          the matters presented;

                                      14.
<PAGE>

               (B) counsel, independent accountants or other persons as to
          matters which the Director or executive officer believed to be within
          such person's professional competence; and

               (C) with respect to a Director, a committee of the Board upon
          which such Director does not serve, as to matters within such
          committee's designated authority, which committee the Director
          believes to merit confidence; so long as, in each case, the Director
          or executive officer acts without knowledge that would cause such
          reliance to be unwarranted.

          (ii)  The termination of any proceeding by judgment, order,
     settlement, conviction or upon a plea of nolo contendere or its equivalent
     shall not, of itself, create a presumption that the person did not act in
     good faith and in a manner which he reasonably believed to be in or not
     opposed to the best interests of the corporation, and, with respect to any
     criminal proceeding, that he had reasonable cause to believe that his
     conduct was unlawful.

          (iii) The provisions of this paragraph (c) shall not be deemed to be
     exclusive or to limit in any way the circumstances in which a person may be
     deemed to have met the applicable standard of conduct set forth by the
     Delaware General Corporation Law.

          (d)   Expenses.  The corporation shall advance, prior to the final
                --------
disposition of any proceeding, promptly following request therefor, all expenses
incurred by any Director or executive officer in connection with such proceeding
upon receipt of an undertaking by or on behalf of such person to repay said
amounts if it should be determined ultimately that such person is not entitled
to be indemnified under this Bylaw or otherwise.

     Notwithstanding the foregoing, unless otherwise determined pursuant to
paragraph (e) of this Bylaw, no advance shall be made by the corporation if a
determination is reasonably and promptly made (1) by the Board of Directors by a
majority vote of a quorum consisting of Directors who were not parties to the
proceeding, or (2) if such quorum is not obtainable, or, even if obtainable, a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, that the facts known to the decision making party at the time
such determination is-made demonstrate clearly and convincingly that such person
acted in bad faith or in a manner that such person did not believe to be in or
not opposed to the best interests of the corporation.

          (e)   Enforcement.  Without the necessity of entering into an express
                -----------
contract, all rights to indemnification and advances to Directors and executive
officers under this Bylaw shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the Director or executive officer.  Any right to indemnification
or advances granted by this Bylaw to a Director or executive officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor.  The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting his claim.  The corporation shall be entitled to raise as a
defense to any

                                      15.
<PAGE>

such action that the claimant has not met the standards of conduct that make it
permissible under the Delaware General Corporation Law for the corporation to
indemnify the claimant for the amount claimed. Neither the failure of the
corporation (including its Board of Directors, independent legal counsel or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he has met the applicable standard of conduct set forth in the Delaware
General Corporation Law, nor an actual determination by the corporation
(including its Board of Directors, independent legal counsel or its
stockholders) that the claimant has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that claimant has not
met the applicable standard of conduct.

          (f) Non-Exclusivity of Rights.  The rights conferred on any person by
              -------------------------
this bylaw shall not be exclusive of any other right which such person may have
or hereafter acquire under any statute, provision of the Certificate of
Incorporation, Bylaws, agreement, vote of stockholders or disinterested
Directors or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office.  The corporation is
specifically authorized to enter into individual contracts with any or all of
its Directors, officers, employees or agents respecting indemnification and
advances, to the fullest extent not prohibited by the Delaware General
Corporation Law.

          (g) Survival of Rights.  The rights conferred on any person by this
              ------------------
Bylaw shall continue as to a person who has ceased to be a Director, officer,
employee or other agent and shall inure to the benefit of the heirs, executors
and administrators of such a person.

          (h) Insurance.  To the fullest extent permitted by the Delaware
              ---------
General Corporation Law, the corporation, upon approval by the Board of
Directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this Bylaw.

          (i) Amendments.  Any repeal or modification of this Bylaw shall only
              ----------
be prospective and shall not affect the rights under this Bylaw in effect at the
time of the alleged occurrence of any action or omission to act that is the
cause of any proceeding against any agent of the corporation.

          (j) Saving Clause.  If this Bylaw or any portion hereof shall be
              -------------
invalidated on any grounds by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each Director and executive officer to
the full extent not prohibited by any applicable portion of this Bylaw that
shall not have been invalidated, or by any other applicable law.

          (k) Certain Definitions.  For the purposes of this Bylaw, the
              -------------------
following definitions shall apply:

              (i) The term "proceeding" shall be broadly construed and shall
          include, without limitation, the investigation, preparation,
          prosecution, defense, settlement, arbitration and appeal of, and the
          giving of testimony in, any threatened, pending or completed action,
          suit or proceeding, whether civil, criminal, administrative or
          investigative.

          include, without limitation, court costs, attorneys' fees, witness
          fees, fines, amounts paid in settlement or judgment and any other
          costs and expenses of any nature or kind incurred in connection with
          any proceeding.

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

               (iv)  References to a "director," "officer," "employee," or
          "agent" of the corporation shall include, without limitation,
          situations where such person is serving at the request of the
          corporation as a director, officer, employee, trustee or agent of
          another corporation, partnership, joint venture, trust or other
          enterprise.

               (v)   References to "other enterprises" shall include employee
          benefit plans; references to "fines" shall include any excise taxes
          assessed on a person with respect to an employee benefit plan; and
          references to serving at the request of the corporation" shall include
          any service as a director, officer, employee or agent of the
          corporation which imposes duties on, or involves services by, such
          director, officer, employee, or agent with respect to an employee
          benefit plan, its participants, or beneficiaries; and a person who
          acted in good faith and in a manner he reasonably believed to be in
          the interest of the participants and beneficiaries of an employee
          benefit plan shall be deemed to have acted in a manner "not opposed to
          the best interests of the corporation" as referred to in this Bylaw.

of the corporation or its transfer agent.  [Del. Code Ann., tit. 8, (S)222]

Director may be given by the method stated in subsection (a), or by facsimile,
telex or telegram, except that such notice other than one which is delivered
personally shall be sent to such address as such Director shall have filed in
writing with the Secretary, or, in the absence of such filing, to the last known
post office address of such Director.

          (c) Address Unknown.  If no address of a stockholder or Director be

appointed with respect to the class of stock affected, specifying the name and
address or the names and addresses of the stockholder or stockholders, or
Director or Directors, to whom any such notice or notices was or were given, and
the time and method of giving the same shall be conclusive evidence of the
statements therein contained.  [Del. Code Ann., tit. 8, (S)222]

          (e) Time Notices Deemed Given.  All notices given by mail, as above
              -------------------------
provided, shall be deemed to have been given as at the time of mailing and all
notices given by facsimile, telex or telegram shall be deemed to have been given
as of the sending time recorded at time of transmission.

          (f) Methods of Notice.  It shall not be necessary that the same method
              -----------------
of giving notice be employed in respect of all Directors, but one permissible
method may be employed in respect of any one or more, and any other permissible
method or methods may be employed in respect of any other or others.

privilege or benefit, or be required to act, or within which any Director may
exercise any power or right, or enjoy any privilege, pursuant to any notice sent
him in the manner above provided, shall not be affected or extended in any

or meeting which shall be taken or held without notice to any such person with

notice had been duly given.  In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the Delaware General Corporation Law, the certificate shall state,
if such is the fact and if notice is required, that notice was given to all
persons entitled to receive notice except such persons with whom communication

required.  Any action or meeting which shall be taken or held without notice to
such person shall have the same force and effect as if such notice had been duly
given.  If any such person shall deliver to the corporation a written notice
setting forth his then current address, the requirement that notice be given to

corporation is such as to require the filing of a certificate under any
provision of the Delaware General Corporation Law, the certificate need not
