                                  OUR COMPANY

    We are a rapidly growing integrated communications provider. We seek to
become the leading provider of telecommunications services for small and
mid-sized businesses in each of the cities we serve. We offer state-of-the-art
telecommunications services to our customers, who today are located throughout
Missouri, Kansas and Texas. These voice and data service offerings include local
and long distance telephone service, Internet access, web hosting, integrated
voice and data transmission over broadband lines and customer premises equipment
sales and services. We offer these services to our customers through a
combination of leased and owned network facilities. We are currently deploying
collocations and transmission equipment throughout our markets to deliver
digital subscriber line service, which will support dedicated high-speed
Internet access and eventually voice services. We expect to have over 130
collocations operational by the end of this year. Our revenue for the year ended
December 31, 1999 was $60.5 million, a 132% increase over 1998.

    We have increased our local access lines in service to over 135,000 and now
serve over 20,000 business customers, making us one of the largest integrated
communications providers in the territory served by Southwestern Bell. We intend
to continue to grow our customer base rapidly. We currently serve 17 markets
that have populations ranging in size from 95,000 to 4.5 million. We average
6,000 lines in each of those markets. We intend to offer our services in an
additional 20 markets before the end of 2001. We expect to expand our operations
in Texas and into Oklahoma in the second quarter of this year and to commence
service in the regions served by Ameritech and BellSouth in 2001. We have
developed systems and network capabilities and have an experienced sales force
and customer service team that position us to rapidly penetrate new markets and
serve a growing number of customers. We believe that our success to date is
largely attributable to our customer-focused philosophy and our aggressive
marketing strategy.

    We have developed a capital-efficient network platform to deliver voice
services to our customers. In most of our markets, we lease substantially all of
the network elements from the incumbent telephone company and use our advanced
back-office systems to combine these elements into integrated Birch-branded
voice services. This network delivery method, which we call the unbundled
network element platform, or UNE-P, has allowed us to offer voice services to
customers located virtually anywhere in our markets and achieve high gross
margins and superior returns on incremental capital invested. UNE-P allows us to
minimize current capital expenditures and maintain design flexibility for the
next generation of telecommunications technology.

    We currently operate 26 data switches and a high-speed network
interconnecting these switches to carry data traffic across our region. We
intend to be one of the first carriers in our markets to deliver broadband
facilities directly to our small and mid-sized business customers. By
implementing digital subscriber line technology to transmit both data and voice
traffic over a single line, we expect to

                                       1
<PAGE>
significantly reduce the per-line costs of providing and leasing telephone
lines. These savings should allow us to offer a more attractive package of data
and voice services to our customers and improve our gross margins. We are
beta-testing technologies provided by third-party vendors that we expect will
allow us to provide voice services over digital subscriber lines.

    We offer our customers simplified packages of voice and high-speed data
services designed for small and mid-sized businesses, which are conveniently
billed on a single invoice. In each of our markets, we deploy a locally based
sales force that consults with our customers to assist them in selecting an
appropriate service package that will meet their needs. Our 170-person direct
sales force is supported by aggressive multi-media advertising campaigns
designed to enhance awareness of the Birch name. We believe that our
customer-oriented approach to small and mid-sized businesses provides us with an
advantage over incumbent telephone companies, who are not focused on these
customers.

                                  OUR STRATEGY

    We believe that our business is poised for rapid expansion and that our
experienced management team is well prepared to execute our focused business
strategy. The key elements of our strategy include:

    - FOCUSING ON SMALL AND MID-SIZED BUSINESS CUSTOMERS;

    - PROVIDING COMPLETE SERVICE PACKAGES THAT ARE TAILORED TO OUR CUSTOMERS;

    - CREATING A STRONG BRAND PRESENCE;

    - DEPLOYING A DIRECT SALES FORCE IN EACH OF OUR MARKETS;

    - INVESTING IN INDUSTRY-LEADING, SCALABLE BACK OFFICE SYSTEMS;

    - MAINTAINING MAXIMUM NETWORK FLEXIBILITY;

    - EXPANDING OUR GEOGRAPHIC REACH; AND

    - GROWING THROUGH ACQUISITIONS.

                                 RECENT EVENTS

    In August 1999, an affiliate of KKR purchased $60.0 million of our preferred
stock and, on March 23, 2000, exercised options to invest an additional
$50.0 million in our company. KKR's investment will be converted into common
stock at the closing of the offering. KKR is our largest stockholder and, after
giving effect to this exercise, KKR's investment would have represented a 51.2%
equity interest as of March 23, 2000. Upon closing of the offering, KKR will own
approximately    % of our outstanding common stock.

    In December 1999, we obtained a $75.0 million senior credit facility, which
was increased to $125.0 million in February 2000. This credit facility provides
for a $25.0 million reducing revolver and $100.0 million in multi-draw term
loans. The revolver is available for general corporate purposes of our
subsidiaries, and the term loans are to be used to finance telecommunications
equipment, inventory, network assets and back office systems.

Use of proceeds..............................  We estimate that our net proceeds from the
                                               offering will be approximately $
                                               million, based on an assumed initial public
                                               offering price of $         per share, or
                                               $         million if the underwriters
                                               exercise their over-allotment option. We plan
                                               to use the net proceeds from the offering to
                                               fund capital expenditures and operating
                                               losses and for general corporate purposes,
                                               including possible future investments,
                                               acquisitions or strategic alliances.

</TABLE>

    The calculation of the number of shares outstanding after the offering is
based on:

    - the number of shares outstanding on March 23, 2000; and

    - conversion of our preferred stock into 41,307,596 shares of common stock,
      which will occur automatically upon completion of the offering.

    Other than the shares issued upon exercise by KKR of its options, this total
does not reflect:

    - shares that may be issued upon the exercise of outstanding options and
      warrants; or

    - shares that are reserved for future issuance pursuant to our employee and
      director stock plans.

    EBITDA consists of earnings before interest, income taxes, depreciation and
amortization. EBITDA is provided because it is a measure of financial
performance commonly used in the telecommunications industry. EBITDA is used by
management and some investors as an indicator of a company's historical ability
to service debt. Management believes that an increase in EBITDA is an indicator
of improved ability to service existing debt, to sustain potential future
increases in debt and to satisfy capital requirements. We have presented EBITDA
to enhance your understanding of our operating results. You should not construe
it as an alternative to operating income, as an indicator of our operating
performance nor as an alternative to cash flows from operating activities as a
measure of liquidity determined in accordance with generally accepted accounting
principles, or GAAP. We may calculate EBITDA differently from other companies.
For further information, see our consolidated financial statements and the
related notes elsewhere in this prospectus.

    The predecessor company is Valu-Line Companies, Inc., which merged with us
in February 1998. Prior to February 1998, Birch had no revenues and was a
development stage company.

    We acquired Boulevard Phone Company, Telesource Communications, Inc. and
TFSnet, Inc. in 1998 and American Local Telecommunications, LLC and Capital
Communications Corporation in 1999. The statement of operations data, other
financial data and operating data in the table include the operations of these
companies beginning on the dates they were acquired. These acquisitions affect
the comparability of the financial data for the periods presented.

                                  RISK FACTORS

    YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS AS WELL AS THE OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE INVESTING IN SHARES OF OUR
COMMON STOCK. IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCURS, OUR BUSINESS COULD
BE HARMED. IN THAT CASE, THE TRADING PRICE OF THE COMMON STOCK COULD DECLINE AND
YOU MIGHT LOSE ALL OR PART OF YOUR INVESTMENT. YOU SHOULD ALSO REFER TO THE
OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, INCLUDING OUR FINANCIAL
STATEMENTS AND THE RELATED NOTES.

                         RISKS RELATED TO OUR BUSINESS

WE HAVE A LIMITED HISTORY UPON WHICH YOU CAN BASE YOUR INVESTMENT DECISION.

    We commenced operations in February 1998, and since that time we have grown
rapidly. As a result of our limited operating history, you have limited
operating and financial data about us upon which to base an evaluation of our
performance and an investment in our common stock. Our ability to provide an
integrated package of bundled telecommunications services on a widespread basis
and to generate operating profits and positive operating cash flow will depend
upon our ability, among other things, to:

    - develop our operational support and other back office systems;

    - obtain state authorizations to operate as a competitive local exchange
      carrier and any other required governmental authorizations;

    - increase awareness of our brand and attract and retain an adequate
      customer base;

    - raise additional capital;

    - attract and retain qualified personnel;

    - enter into and implement interconnection agreements with established
      telephone companies on satisfactory terms; and

    - enter into new markets and successfully compete for business in different
      environments.

    We cannot assure you that we will be able to achieve any of these
objectives, generate sufficient revenues to achieve or sustain profitability,
meet our working capital and debt service requirements or compete successfully
in the telecommunications industry.

WE HAVE A HISTORY OF OPERATING LOSSES, AND WE MAY NOT BE PROFITABLE IN THE
FUTURE.

    We have incurred significant losses since we began operations as a
competitive telecommunications provider and expect to continue to incur losses
in the future as we build our network. For the year ended December 31, 1999, we
had operating losses of $49.7 million and a net loss of $61.8 million. As of
December 31, 1999, we had an accumulated deficit of $79.8 million. We expect to
experience losses during our network and service deployment, which will continue
for the foreseeable future. Prolonged effects of generating losses without
additional funding may restrict our ability to pursue our business strategy.
Unless our business plan is successful, your investment in our common stock may
result in a complete loss of your invested capital.

    If we cannot achieve profitability from operating activities, we may not be
able to meet:

    - our capital expenditure requirements;

    - our debt service obligations; or

    - our working capital needs.

                                       6
<PAGE>
OUR HIGHLY LEVERAGED CAPITAL STRUCTURE LIMITS OUR ABILITY TO OBTAIN ADDITIONAL
FINANCING AND COULD ADVERSELY AFFECT OUR BUSINESS IN SEVERAL OTHER WAYS.

    The level of our outstanding debt greatly exceeds the level of our revenue
and stockholders' equity. As of December 31, 1999, we had $125.8 million of
long-term indebtedness outstanding, including $10.0 million outstanding under
our senior credit facility and $114.7 million of senior notes outstanding. This
indebtedness represented 103.5% of our total capitalization at that date. We
may, and are also permitted under the terms of our debt instruments to, incur
substantial indebtedness in the future.

    Our large amount of indebtedness could significantly impact our business for
the following reasons:

    - it limits our ability to obtain additional financing to complete our
      roll-out plan, to develop new services or to otherwise respond to
      unanticipated competitive pressures;

    - it means that we will need to dedicate a substantial portion of our
      operating cash flow to fund interest expense on our senior credit facility
      and our senior notes, thereby reducing funds available for working
      capital, capital expenditures or other purposes;

    - it makes us vulnerable to interest rate fluctuations because our senior
      credit facility loans bear interest at variable rates;

    - it limits our ability to compete with companies who are not as highly
      leveraged, especially those who may be able to price their service
      offerings at levels below those we can or are willing to match; and

    - it limits our ability to expand into new markets and to react to changing
      market conditions, changes in our industry and economic downturns.

OUR EXISTING DEBT INCLUDES RESTRICTIVE AND FINANCIAL COVENANTS THAT LIMIT OUR
OPERATING FLEXIBILITY.

    Our senior credit facility and the indenture relating to our senior notes
contain covenants that, among other things, restrict our ability to take
specific actions, even if we believe them to be in our best interest. These
include restrictions on our ability to:

    - incur additional debt;

    - pay dividends or distributions on, or redeem or repurchase, capital stock;

    - create liens or negative pledges with respect to our assets;

    - make investments, loans or advances;

    - issue, sell or allow distributions on capital stock of specified
      subsidiaries;

    - enter into sale and leaseback transactions;

    - prepay or defease specified indebtedness;

    - enter into transactions with affiliates;

    - enter into specified hedging arrangements;

    - merge, consolidate or sell our assets; or

    - engage in any business other than telecommunications.

    The senior notes also require us to offer to purchase these notes from the
holders at 101% if we undergo a change of control. In addition, the senior
credit facility imposes financial covenants that require us to comply with
specified financial ratios and tests, including minimum revenues, minimum
EBITDA/maximum EBITDA losses, minimum access lines, senior secured debt to total
capitalization,

                                       7
<PAGE>
maximum capital expenditures, maximum leverage ratios, minimum interest coverage
ratios and pro forma debt service coverage ratios. We cannot assure you that we
will be able to meet these requirements or satisfy these covenants in the
future. If we fail to do so, our debts could become immediately payable at a
time when we are unable to pay them. This could adversely affect our ability to
carry out our business plan and would have a negative effect on our financial
condition.

WE EXPECT TO GROW AND CANNOT GUARANTEE THAT WE WILL BE ABLE TO EFFECTIVELY
MANAGE OUR FUTURE GROWTH.

    If we successfully implement our business plan, our operations will expand
rapidly, and we will be providing packaged telecommunications services on a
widespread basis. This could place a significant strain on our management,
operational, financial and other resources and increase demands on our systems
and controls. Failure to manage our future growth effectively could adversely
affect the expansion of our customer base and service offerings. We cannot
assure you that we will successfully implement and maintain efficient
operational and financial systems, procedures and controls or successfully
obtain, integrate and manage the employees and management, operational,
financial and other resources necessary to manage a developing and expanding
business in our evolving, highly regulated and increasingly competitive
industry.

TO EXPAND AND DEVELOP OUR BUSINESS WE WILL NEED A SIGNIFICANT AMOUNT OF CASH,
WHICH WE MAY BE UNABLE TO OBTAIN.

    The expansion and development of our business and the deployment of our
networks, services and systems will require significant capital expenditures,
working capital and debt service and generate negative operating cash flows.

    The actual amount and timing of our future capital requirements may differ
materially from our estimates as a result of, among other things, the demand for
our services and regulatory, technological and competitive developments,
including additional market developments and new opportunities, in our industry.
Our revenue and costs may also be dependent upon factors that are not within our
control, including regulatory and legislative developments, the response of our
competitors to their loss of customers to us and to changes in technology, the
nature and penetration of services that we may offer and the number of
subscribers and the services for which they subscribe. Due to the uncertainty of
these factors, actual revenues and costs may vary from expected amounts,
possibly to a material degree, and these variations are likely to affect our
future capital requirements.

    We also expect that we will require additional financing or may require
financing sooner than anticipated to complete our roll-out plan or if our
development plans change or prove to be inaccurate. We may also require
additional financing in order to develop new services or to otherwise respond to
changing business conditions or unanticipated competitive pressures. Sources of
additional financing may include commercial bank borrowings, vendor financing,
or the private or public sale of equity or debt securities. If we decide to
raise additional funds through the incurrence of debt, our interest obligations
will increase, and we may become subject to additional or more restrictive
financial covenants, which could impair our ability to develop our business. If
we decide to raise additional funds through the issuance of equity, the
ownership interests represented by the common stock will be diluted. We cannot
assure you that we will be successful in raising sufficient additional capital
on favorable terms or at all. Failure to raise sufficient funds may require us
to modify, delay or abandon some of our future expansion or expenditure plans.

RESISTANCE BY POTENTIAL CUSTOMERS TO ACCEPT US AS A NEW PROVIDER OF
TELECOMMUNICATIONS SERVICES MAY REDUCE OUR ABILITY TO INCREASE OUR REVENUE.

    The success of our service offerings will depend upon, among other things,
the willingness of additional customers to accept us as a new provider of
integrated communications services. We cannot

                                       8
<PAGE>
assure you that we will be successful in overcoming the resistance of potential
customers to change their service provider, particularly those that purchase
services from the traditional telephone companies, or that customers will buy
our services. Any lack of customer acceptance would reduce our ability to
increase our revenue.

IF WE ARE UNABLE TO DEVELOP OR INTEGRATE OUR SYSTEMS OR PROPERLY MAINTAIN AND
UPGRADE THEM, WE MAY NOT BE ABLE TO BILL OUR CUSTOMERS EFFECTIVELY OR PROVIDE
ADEQUATE CUSTOMER SERVICE.

    Sophisticated back office information and processing systems are vital to
our growth and our ability to monitor costs, bill customers, provision customer
orders, achieve operating efficiencies and maintain our operating margins. Our
plans for the development and implementation of these systems rely, for the most
part, on choosing products and services offered by third party vendors and
integrating these products and services in-house to produce efficient
operational solutions. We cannot assure you that we will successfully implement
these systems on a timely basis or that we will implement them at all. We also
cannot assure you that, once implemented, these systems will perform as we
expect. Risks to our business associated with our systems include:

    - failure by these vendors to deliver their products and services in a
      timely and effective manner and at acceptable costs;

    - failure by us to identify all of our information and processing needs
      adequately;

    - failure of our related processing or information systems; or

    - failure by us to effectively integrate new products or services.

    Furthermore, as our suppliers revise and upgrade their hardware, software
and equipment technology, we could encounter difficulties in integrating this
new technology into our business or the new systems may not be appropriate for
our business. In addition, our right to use these systems depends upon license
agreements with third party vendors. Vendors may cancel or elect not to renew
some of these agreements, which may adversely affect us.

WE MAY NEED TO RELY ON THE ESTABLISHED LOCAL TELEPHONE COMPANIES TO IMPLEMENT
OUR SERVICES SUCCESSFULLY. THEIR FAILURE TO COOPERATE WITH US COULD ADVERSELY
AFFECT THE SERVICES WE OFFER.

    We are a recent entrant into the local telecommunications services industry.
The local exchange services market in most states was only recently opened to
competition. There are numerous operating complexities associated with providing
these services. We will be required to develop new products, services and
systems and will need to develop new marketing initiatives to sell these
services. We cannot assure you that we will be able to develop these products
and services.

    We plan to deploy high capacity voice and data switches in most of the
markets we serve. We initially intend to rely on the networks of established
telephone companies or those of new market entrants for some aspects of
transmission. Federal law requires most of the traditional local telephone
companies to lease or "unbundle" elements of their networks and permit us to
purchase the elements we need, thereby decreasing our operating expenses. We
cannot assure you that this unbundling will continue to occur in a timely manner
or that the prices for these elements will be favorable to us. Our current
strategy depends in large part on our ability to provide service to our
customers by leasing all of the network elements necessary to provide local
telephone service from the incumbent telephone company rather than through the
use of our own equipment and facilities. UNE-P allows us to minimize capital
expenditures and permits us to enter new markets quickly, while allowing us to
maintain significant gross margins. If the incumbent local telephone companies
do not cooperate in making UNE-P available, our ability to provide service to
customers could be materially adversely affected.

                                       9
<PAGE>
    In addition, our ability to implement successfully our services will require
the negotiation of interconnection and collocation agreements with established
telephone companies and other new market entrants, which can take considerable
time, effort and expense and is subject to federal, state and local regulation.
Interconnection agreements are agreements between local telecommunications
services providers that set forth the terms and conditions governing how those
providers will interconnect their networks and/or purchase or lease network
facilities and services.

    Our interconnection agreements with Southwestern Bell provide that our
connection and maintenance orders will receive the same attention as
Southwestern Bell's end-user customers and that Southwestern Bell will provide
capacity at key telecommunications intersections to keep call blockage within
industry standards. Accordingly, we depend and will continue to depend on
Southwestern Bell and, as we expand our network, we will depend on other
traditional telephone companies to assure uninterrupted service and competitive
services. Blocked calls result in customer dissatisfaction and risk the loss of
business. Interconnection agreements, such as our agreements with Southwestern
Bell, typically have short terms, requiring us to renegotiate frequently. Some
of our agreements with Southwestern Bell have one year or less remaining before
we will have to renegotiate them. We cannot assure you that we will be able to
renegotiate these interconnection agreements in our existing markets, or
negotiate new interconnection agreements in new markets, on favorable terms. In
addition, the prices set forth in our interconnection agreements may be subject
to significant rate increases at the discretion of the regulatory authority in
each state in which we operate. Our profitability partially depends on these
state-regulated rate structures. We cannot assure you that the rates charged to
us under the interconnection agreements will allow us to offer low enough usage
rates to attract a sufficient number of customers and to operate our business
profitably or at favorable gross margins.

    Many new carriers have experienced difficulties in working with the
established telephone companies with respect to ordering, interconnecting,
leasing premises and implementing the systems used by these new carriers to
order and receive unbundled network elements and wholesale services. We cannot
assure you that established telephone companies will be accommodating to us. If
we are unable to obtain the cooperation of an established telephone company in a
region, our ability to offer local services in this region on a timely and
cost-effective basis would be adversely affected. In addition, both proposed and
recently completed mergers involving regional Bell operating companies and other
competitors could facilitate a combined entity's ability to provide many of the
services we offer, thereby making it more difficult to compete against them.

DIGITAL SUBSCRIBER LINE TECHNOLOGY MAY NOT OPERATE AS EXPECTED ON INCUMBENT
LOCAL CARRIER NETWORKS AND MAY INTERFERE WITH OR BE AFFECTED BY OTHER TRANSPORT
TECHNOLOGIES.

    Our ability to provide digital subscriber line services to potential
customers depends on the quality, physical condition, availability and
maintenance of telephone lines within the control of the incumbent carriers. If
the telephone lines are not adequate, we may not be able to provide digital
subscriber line services to many of our target customers, and this will diminish
our expected revenue. We believe the current condition of telephone lines in
many cases may be inadequate to permit us to fully implement these services. We
also believe that the incumbent carriers may not maintain or improve the
telephone lines in a condition that will allow us to implement our digital
subscriber line services effectively. Further, the incumbent carriers may claim
their lines are not of sufficient quality to allow us to fully implement or
operate our digital subscriber line services. In addition, some customers use
technologies other than copper lines to provide telephone services, and as a
result, digital subscriber line services might not be available to these
customers.

    All transport technologies using copper telephone lines have the potential
to interfere with, or to be interfered with by, other traffic on adjacent copper
telephone lines. This interference could degrade the performance of our services
or make us unable to provide service on selected lines. In addition, incumbent
carriers may claim that the potential for interference by digital subscriber
line technology

                                       10
<PAGE>
permits them to restrict or delay our deployment of this technology. The
telecommunications industry and regulatory agencies are still developing
procedures to resolve interference issues between telecommunications providers,
and these procedures may not be effective. We may be unable to successfully
negotiate interference resolution procedures with incumbent carriers.
Interference, or claims of interference, if widespread, would adversely affect
our speed of deployment, reputation, brand image, service quality and customer
retention and satisfaction.

IF WE ARE UNABLE TO ATTRACT AND RETAIN KEY MANAGEMENT AND PERSONNEL, WE MAY NOT
BE ABLE TO IMPLEMENT OUR BUSINESS PLAN.

    We believe that our future success will be due, in part, to our experienced
management team, including Messrs. Scott, Goldman, Hollingsworth, Lawhon,
Moline, Shackelford and Vranicar, each of whom is party to an employment
agreement. Losing the services of one or more members of our management team
could adversely affect our business and our expansion efforts and possibly
prevent us from:

    - further deploying and improving our operational, financial and information
      systems and controls;

    - hiring and retaining qualified sales, marketing, administrative, operating
      and technical personnel; and

    - training and managing new personnel.

    In addition, competition for qualified employees has intensified in recent
years and may become even more intense in the future. Our ability to implement
our business plan depends on our ability to hire and retain a large number of
new employees each year. Inability to hire sufficient qualified personnel could
impair our ability to increase revenue, and customers could experience delays in
installation of service or experience lower levels of customer care.

WE MAY NOT HAVE THE ABILITY TO DEVELOP STRATEGIC ALLIANCES OR TO MAKE OR
SUCCESSFULLY INTEGRATE ACQUISITIONS NEEDED TO COMPLEMENT OUR EXISTING BUSINESS.

    As part of our growth strategy, we seek to develop strategic alliances and
to make investments or acquire assets or other businesses. We regularly engage
in discussions relating to potential acquisitions. We are unable to predict
whether or when any prospective acquisitions or strategic alliances will occur
or the likelihood of a material transaction being completed on favorable terms
and conditions. Our ability to finance acquisitions and strategic alliances may
be constrained by our degree of leverage at the time of the acquisition. In
addition, our senior credit facility and senior notes may significantly limit
our ability to make acquisitions or enter into strategic alliances and to incur
indebtedness in connection with acquisitions and strategic alliances.

    In addition, if we were to proceed with one or more significant strategic
alliances, acquisitions or investments in which the consideration consists of
cash, we could use a substantial portion of our available cash, including
proceeds of the offering, to consummate the strategic alliances, acquisitions or
investments. The financial impact of acquisitions, investments and strategic
alliances could cause substantial fluctuations in our quarterly and yearly
operating results. Furthermore, if we use our common stock as consideration for
acquisitions, our stockholders would experience dilution of their existing
shares.

    The integration of any future acquisitions or strategic alliances would be
accompanied by the risks commonly encountered in these transactions. These risks
include, among others:

    - the difficulty of assimilating the acquired operations and personnel;

    - the potential disruption of our ongoing business and diversion of
      resources and management time;

                                       11
<PAGE>
    - the inability of management to maximize our financial and strategic
      position by the successful incorporation of licensed or acquired
      technology and rights into our service offerings;

    - the possible inability of management to maintain uniform standards,
      controls, procedures and policies;

    - the risks of entering markets in which we have little or no direct prior
      experience; and

    - the potential impairment of relationships with employees or customers as a
      result of changes in management or otherwise arising out of these
      transactions.

    We cannot assure you that we will be able to integrate acquired businesses
or assets successfully.

A SYSTEM FAILURE COULD CAUSE DELAYS OR INTERRUPTIONS OF SERVICE, WHICH COULD
CAUSE US TO LOSE CUSTOMERS.

    Our success will require that our networks provide competitive reliability,
capacity and security. Some of the risks to our networks and infrastructure
include:

    - physical damage to access lines;

    - power surges or outages;

    - capacity limitations;

    - software defects;

    - lack of redundancy; and

    - disruptions beyond our control.

    These disruptions may cause interruptions in service or reduced capacity for
customers, any of which could cause us to lose customers.

ALL YEAR 2000 PROBLEMS MAY NOT HAVE BEEN ADDRESSED BY OUR SUPPLIERS, AND ANY
SERVICE INTERRUPTION WE EXPERIENCE AS A RESULT OF THESE PROBLEMS MAY CAUSE US TO
LOSE CUSTOMERS.

    The Year 2000 issue generally describes the various problems that may result
from the improper processing of dates and date-sensitive transactions by
computers and other equipment as a result of computer hardware and software
using two digits, rather than four digits, to identify the year in a date. Any
computer programs or systems of our suppliers that have date-sensitive software
may recognize a date using "00" as the year 1900 rather than the year 2000.
While we have experienced no Year 2000 issues to date, and we are not aware of
any material issues for our suppliers, we are continuing to evaluate and
determine whether our significant suppliers are in compliance or have
appropriate plans to remedy Year 2000 issues when their systems interact with
our systems. We do not expect that this will have a material impact on our
operations. However, we cannot assure you that the systems of other companies on
which we rely are Year 2000 compliant, that another company's failure to
successfully convert, or that another company's conversion to a system
incompatible with our systems, would not have an impact on our operations. The
failure of our principal suppliers to be Year 2000 compliant could result in
delays in service deliveries from those suppliers and materially impact our
ability to do business.

                         RISKS RELATED TO OUR INDUSTRY

WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY AGAINST OTHER COMPANIES.

    The telecommunications industry is highly competitive and is affected by the
introduction of new services by, and the market activities of, major industry
participants. Several of our competitors are substantially larger and have
greater financial, technical and marketing resources than we do. We have

                                       12
<PAGE>
not achieved, and do not expect to achieve, a significant market share for any
of the broadband telecommunications services we offer in our target markets. In
particular, larger competitors have advantages over us that could cause us to
lose customers and impede our ability to attract new customers, including:

    - long-standing relationships and brand recognition with customers;

    - financial, technical, marketing, personnel and other resources
      substantially greater than ours;

    - more funds to deploy telecommunications services;

    - potential to lower prices of competitive telecommunications services; and

    - fully-deployed networks.

    We face competition from other current and potential market entrants,
including:

    - domestic and international long distance providers seeking to enter,
      re-enter or expand entry into the local telecommunications marketplace;
      and

    - other domestic and international telecommunications providers, resellers,
      cable television companies, electric utilities and Internet companies.

    A continuing trend toward combinations and strategic alliances in the
telecommunications industry could give rise to significant new competitors. This
could cause us to lose customers and impede our ability to attract new
customers.

FEDERAL COMMUNICATIONS COMMISSION AND STATE REGULATIONS MAY LIMIT THE SERVICES
WE CAN OFFER OR IMPACT OUR ABILITY TO CONDUCT OUR BUSINESS.

    Our networks and the provision of telecommunications services are
extensively regulated at the federal, state and local levels. Existing and
future governmental regulations may greatly influence how we operate our
business, our business strategy and ultimately, our viability. The costs of
complying with federal, state and local regulations and the delays in receiving
required regulatory approvals or the enactment of new adverse regulation or
regulatory requirements may be greater than we anticipate and divert our
resources from implementing our business plan. We cannot predict the future
regulatory framework for our business.

    Our provision of telecommunications services may be subject to the
requirement that we obtain proper authorizations from the FCC or state
commissions. We cannot assure you that the FCC or state commissions will grant
the required authority or refrain from taking action against us if we are found
to have provided services without obtaining the necessary authorizations. If we
do not fully comply with the rules of the FCC or state regulatory agencies,
third parties or regulators could challenge our authority to do business. These
challenges could cause us to incur substantial legal and administrative
expenses.

    Federal law governing the telecommunications industry remains in a state of
flux. The Telecommunications Act remains subject to judicial review and
additional FCC rulemaking, and thus it is difficult to predict what effect the
legislation or these FCC rules will have on us and our operations. There are
currently many regulatory actions underway and being contemplated by federal and
state authorities regarding interconnection pricing, universal service support,
access charge reform, and other issues that could result in significant changes
to the business conditions in the telecommunications industry.

    Our current business strategy depends in large part on our ability to
provide service to our customers through UNE-P. Our ability to provide service
to customers through UNE-P depends in turn on FCC and state commission rulings
requiring incumbent local telephone companies to lease us the

                                       13
<PAGE>
necessary network elements. If those rules are changed by the FCC or state
commissions, or are struck down by the courts, our ability to provide service to
our customers through UNE-P could be materially adversely affected. For example,
the FCC could remove one or more of the necessary elements from the list of
elements that the incumbent telephone companies are required to provide to us.
The FCC could also expand the scope of an existing exception in its rules that
permits incumbent telephone companies to opt not to make UNE-P available in the
highest density geographic areas within the largest 50 metropolitan statistical
areas if they meet certain conditions. If the FCC acts to expand the scope of
the geographic exception to include our target markets, our business could be
materially adversely affected. Some states in our current operating region,
including Texas and Missouri, have gone beyond the FCC's minimum requirements
and independently ordered Southwestern Bell to make UNE-P available throughout
those states under terms more favorable to new telecommunications service
providers than those required by the FCC. We cannot assure you that those
favorable state rulings will remain in place. If UNE-P does not continue to be
available on the favorable terms ordered by the states, our business could be
materially adversely affected.

    The United States Court of Appeals for the Eighth Circuit is currently
considering challenges to the pricing methodology established by the FCC for
setting the rates paid by telecommunications service providers to incumbent
telephone companies for access to network elements. If the court strikes down
some or all of the FCCs's pricing methodology and that methodology is ultimately
replaced with a methodology that imposes higher rates for network elements, we
could be materially adversely affected.

    Federal universal service support mechanisms could increase the costs of
providing service to our customers. We derive revenue from the provision of
interstate and international telecommunications services to end users that may
be subject to the requirement that we contribute to the FCC's Universal Service
Fund based on a percentage of this revenue. The assessment for the first quarter
of 2000 is 5.8995%, and the assessment for the second quarter of 2000 is 5.7101%
of interstate and international end user telecommunications revenue. The
contribution factor varies quarterly at a rate set by the FCC. To the extent the
contribution factor increases, our costs of providing service will increase.

    Our Internet operations are not currently regulated directly by the FCC or
any other governmental agency, other than regulations applicable to businesses
generally. However, the FCC has recently indicated that the regulatory status of
some services offered over the Internet may have to be re-examined. New laws or
regulations relating to Internet services, or existing laws found to apply to
them, may adversely affect our Internet operations.

WE MAY BE UNABLE TO ADAPT TO TECHNOLOGICAL CHANGE.

    The telecommunications industry is subject to rapid and significant changes
in technology, including continuing developments in digital subscriber line
technology. This technology does not presently have widely accepted standards,
and alternative technologies for providing high speed data transport and
networking may develop. The absence of widely accepted standards may delay or
increase the cost of our market entry due to changes in equipment specifications
and customer needs and expectations. We may also rely on a third party for
access to new technologies. In addition, if we acquire new technologies, we may
not be able to implement them as effectively as other companies with more
experience with those technologies and in their markets.

WE MAY FAIL TO ACHIEVE ACCEPTABLE PROFITS ON OUR LONG DISTANCE BUSINESS DUE TO
DECLINING PRICES, LOW CUSTOMER RETENTION RATES AND OUR CONTRACTUAL OBLIGATIONS.

    Prices in the long distance business have declined substantially in recent
years and are expected to continue to decline. In addition, the long distance
industry has a low customer retention rate, as customers frequently change long
distance providers in response to the offering of lower rates or

                                       14
<PAGE>
promotional incentives by competitors. We will rely on other carriers to provide
us with a major portion of our long distance transmission network. Agreements
with these carriers typically provide for the resale of long distance services
on a per-minute basis and may contain minimum volume commitments. The
negotiation of these agreements involves estimates of future supply and demand
for transmission capacity, as well as estimates of the calling patterns and
traffic levels of our future customers. In the event that we fail to meet these
minimum volume commitments, we may have to pay underutilization charges, and, in
the event we underestimate our need for transmission capacity, we may have to
obtain capacity through more expensive means.

AS A NEW DATA TRANSMISSION ENTRANT IN A MARKET, WE MAY INITIALLY GENERATE LOW OR
NEGATIVE GROSS MARGINS.

    As a new entrant in the data transmission business, we expect to generate
low or negative gross margins and substantial start-up expenses as we begin to
offer data transmission services. The success of our data transmission business
will depend upon, among other things, the effectiveness of our sales personnel
in the promotion and sale of our data transmission services, the acceptance of
these services by potential customers, and our ability to hire and train
qualified personnel and further enhance our services in response to future
technological changes. We cannot assure you that we will be successful in these
endeavors.

                         RISKS RELATED TO THIS OFFERING

YOU MIGHT NOT BE ABLE TO SELL YOUR STOCK IF NO MARKET DEVELOPS FOR OUR STOCK.

    Prior to the offering, you could not buy or sell our common stock publicly.
We have filed an application for the quotation of our common stock on The Nasdaq
National Market. However, an active public market for our common stock may not
develop or be sustained after the offering. If a market does not develop or is
not sustained, it may be difficult for you to sell your shares of common stock
at a price that is attractive to you or at all. The initial public offering
price of the common stock will be determined through negotiations between the
representatives of the underwriters and us and may not be representative of the
price that will prevail in the open market.

PROVISIONS IN OUR CHARTER DOCUMENTS MIGHT DETER ACQUISITION BIDS FOR US.

    We intend to amend and restate our certificate of incorporation prior to the
closing of the offering. This amended and restated certificate of incorporation
will provide for, among other things:

    - a classified board of directors;

    - the inability of our stockholders to call special meetings of
      stockholders, to act by written consent, to remove any director or the
      entire board of directors without cause, or to fill any vacancy on the
      board of directors; and

    - advance notice requirements for stockholder proposals.

    Our board of directors will also be permitted to authorize the issuance of
preferred stock without any vote or further action by the stockholders. These
provisions and other provisions under Delaware law could make it more difficult
for a third party to acquire us, even if doing so would benefit our
stockholders.

KKR WILL BENEFICIALLY OWN A SIGNIFICANT INTEREST IN OUR VOTING SECURITIES AFTER
THE OFFERING.

    KKR will beneficially own   % of our outstanding shares of common stock
following the completion of the offering and   % if the underwriters'
overallotment option is exercised in full. As a result, KKR will exercise
significant control over all matters requiring stockholder approval. Under the

                                       15
<PAGE>
terms of a purchasers' rights agreement, KKR is currently entitled to designate
a total of five out of the eleven members of the board of directors and two
members of the compensation committee of the board. The concentrated holdings of
KKR and the presence of its designees on the board of directors may result in a
delay or the deterrence of possible changes in our control, which may reduce the
market price of our common stock. In addition, KKR and its affiliates have the
right to veto many actions that we may take, including any change in our capital
stock, any payments of dividends, any change in the composition of our board,
any affiliate transactions, any consolidation, reorganization, merger or similar
transaction, any change in our governing documents or any voting or similar
agreement concerning our capital stock, as well as specified operating decision,
including, but not limited to, incremental indebtedness, investments and
geographic expansion.

OUR MANAGEMENT WILL HAVE BROAD DISCRETION IN APPLYING THE NET PROCEEDS OF THIS
OFFERING.

    At an initial offering price of $  and after deducting the underwriting
discount and other expenses of the offering, we will receive net proceeds of
approximately $      . We have not yet determined the specific dollar amount of
net proceeds to be allocated to any of the possible uses indicated in "Use of
Proceeds." Accordingly, our management will have broad discretion in applying
the net proceeds of the offering. Management's allocation of the net proceeds
will affect how our business evolves. We cannot assure you that management will
choose to spend these proceeds in areas that benefit our business. In addition,
we cannot assure you that management will choose to allocate proceeds to further
our current business strategy.

FUTURE SALES OF SHARES BY EXISTING STOCKHOLDERS COULD AFFECT OUR STOCK PRICE.

    If our existing stockholders sell substantial amounts of our common stock in
the public market following the offering, the market price of our common stock
could decline. Based on shares outstanding as of March 15, 2000, upon completion
of the offering we will have outstanding       shares of common stock, assuming
no exercise of the underwriters' over-allotment option. Of these shares, only
the       shares of common stock sold in the offering will be freely tradeable,
without restriction, in the public market.      additional shares will be
eligible for sale in the public market immediately upon completion of the
offering. After the lockup agreements pertaining to the offering expire
180 days from the date of this prospectus, an additional       shares will be
eligible for sale in the public market. In addition, the 4,892,259 shares
subject to outstanding options and warrants and             shares reserved for
future issuance under our stock option and purchase plans are not available for
sale for 180 days from the date of this prospectus. Following the offering, we
intend to file a registration statement on Form S-8 under the Securities Act
covering approximately       shares of common stock issued or issuable upon the
exercise of stock options, subject to outstanding options or reserved for
issuance under our employee and director stock plans.

YOU WILL INCUR IMMEDIATE AND SUBSTANTIAL DILUTION.

    The initial public offering price is substantially higher than the pro forma
net book value per share of the outstanding common stock. As a result, investors
purchasing common stock in the offering will incur immediate substantial
dilution in the amount of $  per share. In addition, we have issued options and
warrants to acquire common stock at prices significantly below the initial
public offering price. To the extent these outstanding options and warrants are
exercised, there will be further dilution to investors in this offering.

OUR STOCK DOES NOT HAVE A TRADING HISTORY AND MAY BE EXTREMELY VOLATILE BECAUSE
WE OPERATE IN A RAPIDLY CHANGING INDUSTRY.

    The trading price of our common stock is likely to be volatile. The stock
market has experienced extreme volatility, and this volatility has often been
unrelated to the operating performance of

                                       16
<PAGE>
particular companies. We cannot be sure that an active public market for our
common stock will develop or continue after the offering. Investors may not be
able to sell their common stock at or above our initial public offering price or
at all. Prices for the common stock will be determined in the marketplace and
may be influenced by many factors, including variations in our financial
results, changes in earnings estimates by industry research analysts, investors'
perceptions of us and general economic, industry and market conditions.

OUR OFFICERS AND DIRECTORS EXERT SUBSTANTIAL INFLUENCE OVER US.

    Our executive officers, directors and entities affiliated with them together
beneficially own a substantial percentage of our outstanding common stock. As a
result, these stockholders are able to exercise substantial influence over all
matters requiring approval by our stockholders, including the election of
directors and approval of significant corporate transactions. This concentration
of ownership may also have the effect of delaying or preventing a change in our
control.

THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT MAY NOT BE ACCURATE
INDICATORS OF OUR FUTURE PERFORMANCE.

    This prospectus contains forward-looking statements within the meaning of
the federal securities laws. Discussions containing forward-looking statements

<PAGE>
                                USE OF PROCEEDS

    We estimate that our net proceeds from the sale of the             shares of
common stock will be approximately $   million, or $   million if the
underwriters exercise their over-allotment option in full, after deducting the
estimated underwriting discount and estimated offering expenses of $   million
payable by us.

    We expect to use the net proceeds from the offering and borrowings under our
senior credit facility to fund capital expenditures for network facilities and
back office systems, to fund operating losses and for general corporate
purposes, including possible future investments, acquisitions or strategic
alliances. Pending these uses, we plan to invest the net proceeds in investment
grade, interest-bearing securities.

                                DIVIDEND POLICY

    We have never paid or declared any cash dividends on our common stock and do
not anticipate paying cash dividends in the foreseeable future. We currently
intend to retain all future earnings, if any, for use in the operation of our
business and to fund future growth. The terms of our senior credit facility and
our senior notes indenture restrict our ability to declare and pay dividends on
our common stock.

                                 CAPITALIZATION

    The following table sets forth our capitalization as of December 31, 1999:

    - on an actual basis;

    - on a pro forma basis to give effect to (a) the exercise by KKR of its
      options to invest an additional $50.0 million in our company and (b) the
      conversion of all outstanding shares of our preferred stock into common
      stock, which will occur automatically upon completion of the offering;

    - on a pro forma as adjusted basis to give effect to the pro forma items
      listed above and reflect the application of the net proceeds from the sale
      of             shares of common stock in the offering at an assumed
      offering price of $      per share.

    You should read this table in conjunction with our consolidated financial
statements and the related notes, "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Use of Proceeds" included
elsewhere in this prospectus.

                                    DILUTION

    Dilution is the amount by which the offering price paid by the purchasers of
the common stock to be sold in the offering will exceed the net tangible book
value per share of common stock after the offering. Net tangible book value per
share is determined at any date by subtracting our total liabilities from the
total book value of our tangible assets and dividing the difference by the
number of shares of common stock deemed to be outstanding at that date.

    Our net tangible book value as of December 31, 1999, after giving pro forma
effect to (1) the exercise by KKR of its options to invest an additional
$50.0 million in our company and (2) the conversion of all outstanding shares of
our preferred stock into common stock, which will occur automatically upon
completion of the offering, would have been $      million or $      per share.
After giving effect to the receipt of approximately $      million of estimated
net proceeds from the sale of   million shares of common stock in the offering
at an assumed offering price of $      per share, our pro forma net tangible
book value at December 31, 1999 would have been approximately $      million or
$      per share. This represents an immediate increase in pro forma net
tangible book value of $      per share to existing stockholders and an
immediate dilution of $      per share to investors purchasing shares of common
stock in the offering. The following table illustrates the substantial and
immediate per share dilution to new investors:

    The table above assumes no exercise of stock options or warrants outstanding
as of December 31, 1999. As of December 31, 1999, there were options outstanding
to purchase a total of 1,980,850 shares of common stock at a weighted average
exercise price of $3.59 per share. We have granted 2,256,675 additional options
since that date. As of December 31, 1999, there were warrants outstanding to
purchase a total of 1,409,734 shares of common stock at an exercise price of
$0.01 per share. To the extent any of these options and warrants are exercised,
there may be further dilution to new investors.

               SELECTED CONSOLIDATED FINANCIAL AND OPERATING DATA

    The following table sets forth our selected consolidated financial and
operating data for the periods indicated. Our statement of operations data and
other financial data for the years ended December 31, 1997, 1998 and 1999 and
our balance sheet data as of December 31, 1998 and 1999, as well as the
statement of operations data, other financial data and balance sheet data for
the predecessor company as of and for the year ended December 31, 1997, have
been derived from, and is qualified by reference to, consolidated financial
statements included elsewhere in this prospectus, which Ernst & Young LLP, our
independent auditors, have audited.

    EBITDA consists of earnings before interest, income taxes, depreciation and
amortization. EBITDA is provided because it is a measure of financial
performance commonly used in the telecommunications industry. EBITDA is used by
management and some investors as an indicator of a company's historical ability
to service debt. Management believes that an increase in EBITDA is an indicator
of improved ability to service existing debt, to sustain potential future
increases in debt and to satisfy capital requirements. We have presented EBITDA
to enhance your understanding of our operating results. You should not construe
it as an alternative to operating income, as an indicator of our operating
performance nor as an alternative to cash flows from operating activities as a
measure of liquidity determined in accordance with GAAP. We may calculate EBITDA
differently from other companies. For further information, see our consolidated
financial statements and the related notes elsewhere in this prospectus.

    The predecessor company is Valu-Line, which merged with us in
February 1998. Prior to February 1998, Birch had no revenues and was a
development stage company.

    We acquired Boulevard, Telesource and TFSnet in 1998 and American Local and
Capital in 1999. The statement of operations data, other financial data and
operating data in the table include the operations of these companies beginning
on the dates they were acquired. These acquisitions affect the comparability of
the financial data for the periods presented.

OVERVIEW

    We were organized on December 23, 1996 to become a leading provider of
telecommunications services for small and mid-sized businesses in our target
markets. From that date until the February 1998 acquisition of Valu-Line, our
predecessor, we were a development stage company with no revenue and principal
activities consisting of procuring governmental authorizations, raising capital,
hiring management and other key personnel, designing and developing our
telephone networks, acquiring equipment and facilities, negotiating resale and
interconnection agreements and pursuing acquisition opportunities. We had no
assets, liabilities or financial activity prior to January 1, 1997.

    The following is a summary of our major transactions and events.

March 2000                   KKR exercised its options to purchase an additional
                             $50.0 million series F preferred stock.

FACTORS AFFECTING OPERATIONS

    REVENUE.  We generate most of our revenue from the sale of our voice and
data products, including local and long distance telephone service, Internet
access and customer premises equipment to small and mid-sized business customers
in various markets in Missouri, Kansas and Texas. Revenue from local services
consists of charges for basic local service and custom calling features. We
offer local telephone service at a discount to the competing incumbent provider
of telecommunications services and offer long distance service at flat
per-minute rates. We offer customer premises equipment and related services at
negotiated rates generally consistent with other competitors. We also offer data
services in select markets primarily at flat monthly rates. We expect that over
the near term these services will continue to be the principal components of our
revenue.

    Our revenue consists of monthly recurring charges and usage charges. Monthly
recurring charges include the fees paid by our customers for lines in service,
additional features on those lines and collocation space. Usage charges consist
of fees paid for each call made generally measured by the minute but also
measured by the call. Additionally, revenue from customer premises equipment
sales is recognized upon project completion.

    OPERATING EXPENSES.  Our primary operating expenses are cost of services and
selling, general and administrative expenses.

    COST OF SERVICES.  Our cost of services includes the cost of leasing
unbundled network elements from the incumbent telephone company for combination
into Birch-branded voice services and purchasing the complete "bundle" of
traditional incumbent telephone company services for resale to our local service
subscribers. We lease local telephone network components to provide service for
our customers under an interconnection agreement with the incumbent telephone
company in our target markets. In markets where we have a local circuit switch,
we can avoid leasing the switch and related features from the incumbent
telephone company, which improves our gross margins.

    Incumbent telephone companies typically charge both a start-up fee as well
as a monthly recurring fee for use of their central offices for collocation of
transmission equipment. Physically collocating our transmission equipment in or
near existing incumbent telephone company switching offices allows us to combine
leased digital subscriber lines with our data transmission switches to provide
high speed data services and, eventually, voice and data services over a single
digital subscriber line. We also invest in transmission and distribution
electronics equipment associated with our switches. All of these costs are
reflected in our cost of services.

    Our primary long distance expenses are expenses associated with network
access and our leased long distance network. We purchase long distance capacity
from third party providers for all calls terminating outside of our network.

    Our primary expense associated with providing data services to our customers
is the cost of leasing transmission facilities. Our primary expense associated
with customer premises equipment is the cost of purchasing equipment from
manufacturers and labor for service and equipment installation.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Our selling, general and
administrative expenses include selling and marketing costs and customer
service, billing, corporate administration, personnel and network maintenance
expenses.

    We employ a direct sales force in each of our target markets. To attract and
retain a highly qualified sales force, we offer our sales personnel a
compensation package that emphasizes commissions. We expect to incur significant
selling and marketing costs as we expand our operations.

    We have implemented and continue to refine tailored systems for operations
support systems and other back office systems that provision and track customer
orders from point of sale to the installation

                                       24
<PAGE>
and testing of service. Along with the development costs of these systems, we
also incur ongoing expenses for customer service and billing systems. As our
strategy stresses the importance of personalized customer service, we expect
that our customer service department will become a larger part of our ongoing
administrative expenses. We also expect billing costs to increase as the number
of our customers and the call volume increase. We incur other costs and
expenses, including the costs associated with maintenance of our network,
administrative overhead, office leases and bad debt. We expect that these costs
will grow significantly as we expand our operations and that administrative
overhead will be a large portion of these expenses during the expansion phase of
our business. However, we expect these expenses to become a smaller percentage
of our revenue as we build our customer base.

    We have experienced operating losses since inception as a result of efforts
to build our customer base, develop and construct network infrastructure, build
internal staffing, develop systems and expand into new markets. We expect to
continue to focus on increasing our customer base and geographic coverage.
Accordingly, we expect that cost of services, selling, general and
administrative expenses, and capital expenditures will continue to increase
significantly, all of which may have a negative impact on operating results. The
projected increases in capital expenditures will continue to generate negative
cash flows for at least the next several years as we develop and construct our
voice and data networks. We may also be forced to change our pricing policies to
respond to a changing competitive environment, and we cannot assure you that we
will be able to maintain our gross and operating margins. We cannot assure you
that growth in our revenue or customer base will continue or that we will be
able to achieve or sustain profitability or positive cash flows.

RESULTS OF OPERATIONS

    BIRCH TELECOM, INC.

    YEAR ENDED DECEMBER 31, 1999 COMPARED TO YEAR ENDED DECEMBER 31, 1998

    REVENUE.  Revenue increased 132.1% to $60.5 million for 1999 compared to
$26.1 million for 1998. The increase in revenue was principally a result of new
customer sales in new and existing markets and the acquisitions of Capital in
March 1999 and American Local in February 1999. As a percentage of total
revenue, communications services were 87.5% for 1999 and 83.5% for 1998, and
equipment sales were 12.5% for 1999 and 16.5% for 1998.

    COST OF SERVICES.  Cost of services increased 145.5% to $46.4 million for
1999 compared to $18.9 million for 1998. The increase in cost of services was
primarily the result of associated revenue increases. Gross margins increased
96.9% to $14.2 million (23.4% of revenue) for 1999 compared to $7.2 million
(27.6% of revenue) for 1998. The decline in gross margin as a percentage of
revenue was principally the result of a greater percentage of revenue being
derived from resold local service during 1999 compared to 1998. Additionally,
long distance margins declined as a result of competitive pricing pressures.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 236.4% to $53.0 million for 1999 compared to
$15.8 million for 1998. The increase in expense was primarily a result of
supporting and attracting customers in new and existing markets, market launches
in Texas and the acquisitions of Capital and American Local each of which
affected wages, rent and advertising expense. Additionally, we had 935 employees
at December 31, 1999 compared to 345 employees at December 31, 1998. EBITDA, a
commonly used measure by securities analysts of earnings before deducting
interest, taxes, depreciation and amortization, decreased 353.6% to a loss of
$38.9 million for 1999 compared to a loss of $8.6 million for 1998.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased
369.2% to $10.8 million for 1999 compared to $2.3 million for 1998. The increase
in depreciation and amortization was

                                       25
<PAGE>
primarily attributable to the depreciation of network assets added in our
markets and the amortization of intangible assets related to acquisitions.

    INTEREST.  Interest expense increased 82.2% to $15.0 million for 1999
compared to $8.3 million for 1998. The increase in interest expense was
primarily a result of a full year of interest charges on our senior notes sold
in June 1998. Interest income remained virtually unchanged at $2.9 million in
1999 and 1998. Interest income is primarily derived from pledged securities
purchased in connection with our senior notes.

    NET LOSS.  Net loss increased 281.3% to $61.8 million for 1999 compared to
$16.2 million for 1998.

    YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

    REVENUE.  Revenue was $26.1 million for 1998, resulting from the
acquisitions of Valu-Line, Boulevard, Telesource and TFSnet and new customer
sales from new markets. There was no revenue for 1997 because we were in the
developmental stage. In addition to revenue generated as a result of
acquisitions in 1998, revenue was generated from the sale of local telephone
services to new customers.

    COST OF SERVICES.  Cost of services and gross margin totaled $18.9 million
and $7.2 million, respectively, for 1998 as a result of the associated revenue
increases.

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased $14.0 million to $15.8 million for 1998
compared to $1.8 million for 1997. The increase in expense was primarily a
result of the Valu-Line, Boulevard, Telesource and TFSnet acquisitions and
opening five new markets in 1998. Additionally, we expanded our engineering and
operations staff in preparation for switch deployment. EBITDA decreased 382.4%
to a loss of $8.6 million for 1998 compared to a loss of $1.8 million for 1997.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased to
$2.3 million for 1998 compared to $27,000 for 1997, most of which was
attributable to the fixed and intangible assets acquired in the Valu-Line,
Boulevard, Telesource and TFSnet acquisitions.

    INTEREST.  Interest expense was $8.2 million for 1998 primarily from
interest charges on the senior notes. There was no interest expense in 1997.
Interest income was $2.9 million in 1998 compared to $14,000 for 1997 primarily
as a result of invested funds received from the senior notes.

    NET LOSS.  Net loss was $16.2 million for 1998 compared to $1.8 million for
1997.

    VALU-LINE COMPANIES, INC. (PREDECESSOR COMPANY)

    YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

    REVENUE.  Revenue increased 27.1% to $16.8 million for 1997 compared to
$13.2 million for 1996. The increase was primarily a result of entering the
local service market in March 1997 and long distance volumes increasing faster
than the decline in long distance pricing. Customer premises equipment sales
were 18% of revenue, or $3.0 million, for 1997 compared to 19.1% of revenue, or
$2.5 million, for 1996.

    COST OF SERVICES.  Cost of services increased 35.4% to $11.8 million for
1997 compared to $8.7 million for 1996. The increase was primarily a result of
associated revenue increases. Gross margin increased 11.0% to $5.0 million, or
29.5% of revenue, for 1997 compared to $4.5 million, or 33.8% of revenue, for
1996. The decrease in gross margin as a percentage of revenue was primarily a
result of low margins on resold local service, which started in March 1997.

                                       26
<PAGE>
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased 14.2% to $4.1 million for 1997 compared to
$3.6 million for 1996. The increase in expense was primarily a result of sales
commissions related to increased business volumes and increased customer service
expenditures associated with the commencement of local service. EBITDA decreased
1.7% to $892,000 for 1997 compared to $907,000 for 1996. The decrease in EBITDA
was primarily a result of the start-up costs associated with offering local
service.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization increased 9.6%
to $341,000 for 1997 compared to $311,000 for 1996.

    INTEREST EXPENSE.  Interest expense was $97,000 for 1997 compared to
$102,000 for 1996.

    INCOME TAXES.  Income taxes decreased 9.3% to $186,000 for 1997 compared to
$205,000 for 1996.

    NET INCOME.  Net income was $268,000 for 1997 compared to $289,000 for 1996.

LIQUIDITY AND CAPITAL RESOURCES

    Our total assets increased to $147.0 million at December 31, 1999 from
$134.1 million at December 31, 1998. This increase was primarily the result of
capital outlays for expansion of our local and data networks and development of
operations support systems and automated back office systems, partially offset
by the use of cash to fund operations. At December 31, 1999, our current assets
of $38.8 million exceeded current liabilities of $25.4 million, resulting in
working capital of $13.4 million, representing a decrease of $36.3 million
compared to $49.7 million at December 31, 1998. At December 31, 1998, our
current assets of $61.1 million exceeded current liabilities of $11.4 million,
resulting in working capital of $49.7 million. The decrease in working capital
was primarily attributable to the use of cash to fund operations and capital
outlays for expansion of our network, support systems and back office systems.
Pledged securities to satisfy interest payments on our senior notes amounted to
$23.4 million at December 31, 1999 and $37.8 million at December 31, 1998.

    OPERATING ACTIVITIES.  Net cash used in operating activities was
$53.2 million for the year ended December 31, 1999 compared to $10.6 million for
the year ended December 31, 1998. Net cash used in operating activities was
primarily used to fund our net losses of $61.8 million in 1999 and
$16.2 million in 1998.

    INVESTING ACTIVITIES.  Net cash used in investing activities was
$31.8 million for the year ended December 31, 1999 compared to $67.1 million for
the year ended December 31, 1998. In 1999, net cash used in investing activities
was primarily used for the purchase of property and equipment related to the
expansion of our networks, support systems and back office systems of
$41.4 million and acquisitions of $4.8 million, partially offset by net proceeds
from the sale of pledged securities of $16.1 million for the semi-annual
interest payments on the senior notes. In 1998, net cash used in investing
activities was primarily used for the purchase of pledged securities related to
our senior notes of $44.2 million, acquisitions of $7.8 million and purchases of
property and equipment related to the expansion of the network, support systems
and back office systems of $21.6 million, partially offset by net proceeds from
the sale of pledged securities of $7.7 million.

    FINANCING ACTIVITIES.  Net cash provided by financing activities was
$50.3 million for the year ended December 31, 1999 compared to $117.3 million
for the year ended December 31, 1998. In 1999, net cash provided by financing
activities was primarily a result of $70.0 million in proceeds from the sale of
series D and series F preferred stock and borrowings of $10.0 million under our
senior credit facility, partially offset by the redemption of series C and
series E preferred stock of $18.6 million and the payment of financing costs
related to the series D and series F preferred stock and on our senior credit
facility of $8.8 million.

                                       27
<PAGE>
    In 1998, net cash provided by financing activities was primarily a result of
proceeds of $114.7 million from the private offering of our senior notes. These
senior notes bear interest at a fixed rate of 14% per annum and are due in
June 2008. Subject to limitations, we may redeem a portion of these senior notes
prior to their maturity date if we pay a designated premium. The indenture with
respect to the senior notes contains a number of restrictive financial and
operational covenants with which we must comply.

    In February 2000, we increased the capacity of our $75.0 million senior
credit facility to $125.0 million. This credit facility provides for a
$25.0 million reducing revolver and $100.0 million in multi-draw term loans. The
revolver is available for general corporate purposes of our subsidiaries and the
term loans are to be used to finance telecommunications equipment, inventory,
network assets and back office systems. The senior credit facility is secured by
a perfected first priority security interest in substantially all of our assets
and capital stock of our subsidiaries and contains a number of financial and
operational covenants with which we must comply. Among other things, the
covenants require us to maintain specified levels of revenue, EBITDA, ratio
levels and access lines and restrict our ability to incur additional
indebtedness, pay dividends, enter into related party transactions or sell our
assets.

    In March 2000, KKR exercised its options to purchase an additional
$50.0 million of our series F preferred stock.

    The development and expansion of our business will continue to require
significant capital to fund capital expenditures, working capital and debt
service and will generate negative operating cash flows.

    Our principal capital expenditure requirements will include:

    - the purchase, installation, and expansion of switches and transmission
      equipment for our local and data networks; and

    - the further development of operations support systems and automated back
      office systems.

We do not believe that the growth of our long distance and customer premises
equipment business will require significant capital expenditures.

    Our business plan calls for us to offer our services in an additional 20
markets before the end of 2001. We expect to expand our operations in Texas and
into Oklahoma in the second quarter of this year and to commence service in the
regions served by Ameritech and BellSouth in 2001. We currently estimate that
the cash required to fund these capital expenditures will be approximately
$225.0 million over the next two years. We will need additional cash to fund our
working capital needs, debt service requirements and operating losses. Until we
begin to generate positive cash flow from operations, these liquidity
requirements will need to be financed with additional debt and equity capital.
In addition, depending on prevailing capital market conditions, we may choose to
repurchase all or a portion of our senior notes. We believe that our current
resources, including availability under our senior credit facility, together
with the net proceeds from the offering, will be sufficient to satisfy our
liquidity needs for at least the next 12 months.

    Thereafter, we will need substantial additional capital to finance our
business plan. If our plans or assumptions change, if our assumptions prove to
be inaccurate, or if we experience unexpected costs or competitive pricing
pressures, we will be required to seek additional capital sooner than we
currently expect. In particular, if we elect to pursue acquisition opportunities
or open additional markets, our cash needs may increase substantially. We cannot
assure you that our current projection of cash flow and losses from operations,
which will depend upon numerous future factors and conditions, many of which are
outside of our control, will be accurate. Actual results will almost certainly
vary materially from our current projections. The cost of expanding our network
services and sales efforts, funding

                                       28
<PAGE>
other strategic initiatives and operating our business will depend on a variety
of factors, including, among other things:

    - the number of subscribers and the services for which they subscribe;

    - the nature and penetration of services that we may offer;

    - regulatory and legislative developments; and

    - the response of our competitors to their loss of customers to us and to
      changes in technology.

    We intend to seek additional debt and equity financing to fund our future
liquidity needs. We cannot assure you that we will be able to raise additional
capital on satisfactory terms or at all. If we decide to raise additional funds
through the incurrence of debt, our interest obligations will increase and we
may become subject to additional or more restrictive financial covenants. In
addition, the terms of our senior credit facility and our senior notes each
restrict our ability to obtain additional debt financing. If we decide to raise
additional funds through the issuance of equity, the ownership interests
represented by the common stock will be diluted. In the event that we are unable
to obtain additional capital or to obtain it on acceptable terms or in
sufficient amounts, we may be required to delay the development of our network
and business plans or take other actions that could materially and adversely
affect our business, operating results and financial condition.

IMPACT OF THE YEAR 2000 ISSUE

    The Year 2000 issue results from computer programs being written using two
digits rather than four to define the year. Any of our computer programs or
systems, or those of our suppliers, that have 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 miscalculation causing the disruption of
operations, including among other things:

    - a temporary inability to process transactions;

    - a temporary inability to send invoices;

    - a temporary inability to engage in normal business activities; and

    - interruptions of customer care.

    We did not experience any problems on January 1, 2000 and to date, we have
not experienced, nor are we aware of, any material Year 2000 issues with any of
our internal systems or our services, and we do not anticipate experiencing any
issues in the future. Further, we are unaware of any issues with our vendors,
suppliers or customers that will materially affect us.

    We believe that we have identified all major computers, software
applications and related equipment used in connection with our internal
operations that will need to be modified, upgraded or replaced to minimize the
possibility of a material disruption to our business. We have completed
assessing the potential impact of Year 2000 issues on these computers, equipment
and applications and have modified, upgraded and replaced major systems that we
believe have Year 2000 issues.

    In addition to computers and related information, operation, and network
systems, the operation of office systems, facilities and equipment, such as fax
machines, security systems and other common office devices, may have Year 2000
issues that have not yet surfaced. We will continue to monitor the performance
of these office systems, equipment and facilities.

    We expect that we will be able to resolve any significant Year 2000 issues
we have identified with third party suppliers of components of
telecommunications services and our key subcontractors. However, because we have
no control over the actions of these parties, they may not remediate any or all
of the Year 2000 issues identified. Any failure of any of these third parties to
timely resolve Year

                                       29
<PAGE>
2000 issues with either their products sold to us, or their systems could have a
material adverse effect on our business, operating results and financial
condition. In addition, the delivery of our services also depends on the
operation of the networks of many local exchange carriers and long distance
carriers with whom we must interact as part of our normal business operations,
but with whom we do not have formal contractual arrangements. Consequently,
failure of these carriers' networks to fully operate as a result of Year 2000
issues could also affect our operations. To our knowledge, none of these
networks experienced any problems on or since January 1, 2000.

    Our total cost to date to proactively address our Year 2000 issues has not
been material. The cost of addressing Year 2000 issues is reported as a general
and administrative expense.

    We believe we identified and resolved all Year 2000 issues that could
materially and adversely affect our business operations. However, for the
reasons discussed above, we believe that it is not possible to determine with
complete certainty that all Year 2000 issues affecting us have been identified
or corrected and we may not know that this is true for several months. As a
result, we believe that the following consequences are possible:

    - operational inconveniences and inefficiencies for us that will divert our
      management's time and attention and our financial and human resources from
      ordinary business activities;

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

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

    We developed contingency plans to be implemented if our efforts to identify
and correct Year 2000 issues affecting our internal systems were ineffective. We
have adopted the Year 2000 contingency plans as our standard operational
contingency plans. Our contingency plans are designed to minimize the
disruptions or other adverse effects. Our plans include:

    - accelerated replacement of affected equipment or software;

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

    - increased work hours for our personnel; and

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

    Our implementation of any of these contingency plans could require us to
expend additional funds and could have a material adverse effect on our
business, operating results and financial condition. Our efforts in this regard,
if necessary, will be to minimize expense associated with the implementation and
use of any contingency planning with our objective to employ the least costly
plan necessary to address the relevant operational issues.

IMPACT OF INFLATION

    We do not believe that inflation has had a significant impact on our
consolidated operations.

SEASONALITY

    Our business is not considered to be seasonal.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

    We do not have operations subject to risks of foreign currency fluctuations,
nor do we use derivative financial instruments in our operations or investment
portfolio. Our earnings are affected by

                                       30
<PAGE>
changes in interest rates as our long term debt under our senior credit facility
has variable interest rates based on either the prime rate or LIBOR. Our
exposure to variable interest rate risk during 1999 was insignificant due to our
level of floating rate borrowings. However, if interest rates for our long term
debt under our senior credit facility had averaged 10% more and the full amount
available under our senior credit facility had been outstanding for the entire
year, our interest expense would have increased, and loss before taxes would
have increased by $12.5 million for the year ended December 31, 1999. These
amounts are determined by considering the impact of the hypothetical interest
rates on our borrowing cost and outstanding debt balances. These analyses do not
consider the effects of the reduced level of overall economic activity that
could existing in this environment. Further, in the event of a change of this
magnitude, management would likely take actions to further mitigate our exposure
to the change. However, due to the uncertainty of the specific actions that
would be taken and their possible effects, the sensitivity analysis assumes no
changes in our financial structure. We had $114.7 million of senior notes
outstanding as of December 31, 1999. These notes bear interest at a fixed rate
of 14% and are not subject to risk from interest rate fluctuations.

RECENTLY ISSUED ACCOUNTING STANDARDS

    In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which supersedes SFAS No. 80, "Accounting
for Futures Contracts," SFAS No. 105, "Disclosure of Information About Financial
Instruments with Off-Balance-Sheet Risk and Financial Instruments with
Concentration of Credit Risk," and SFAS No. 119, "Disclosures about Derivative
Financial Instruments and Fair Value of Financial Instruments," and also amends
some aspects of other SFAS's previously issued. SFAS No. 133 establishes
accounting and reporting standards for derivative instruments and hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the balance sheet and measure those instruments at fair
value. SFAS No. 133 is effective for our consolidated financial statements for
the year ending December 31, 2001. We do not expect the impact of SFAS No. 133
to be material in relation to our consolidated financial statements.

                                    BUSINESS

OVERVIEW

    We are a rapidly growing integrated communications provider. We seek to
become the leading provider of telecommunications services for small and
mid-sized businesses in each of the cities we serve. We offer state-of-the-art
telecommunications services to our customers, who today are located throughout
Missouri, Kansas and Texas. These voice and data service offerings include local
and long distance telephone service, Internet access, web hosting, integrated
voice and data transmission over broadband lines and customer premises equipment
sales and services. We offer these services to our customers through a
combination of leased and owned network facilities. We are currently deploying
collocations and transmission equipment throughout our markets to deliver
digital subscriber line service, which will support dedicated high-speed
Internet access and eventually voice services. We expect to have over 130
collocations operational by the end of this year. Our revenue for the year ended
December 31, 1999 was $60.5 million, a 132% increase over 1998.

BUSINESS STRATEGY

    We believe that our business is poised for rapid expansion and that our
experienced management team is well prepared to execute our focused business
strategy. The key elements of our strategy include:

    FOCUSING ON SMALL AND MID-SIZED BUSINESS CUSTOMERS

    We focus on meeting the needs of small and medium-sized businesses in each
    of the cities we serve. Our tailored service offerings, direct sales model,
    and proactive customer service approach allow us to differentiate ourselves
    and achieve significant penetration into this very large, established
    customer base. We believe small and medium-sized businesses have not
    received a satisfying level of attention from the incumbent telephone
    companies, are unaware of their telecommunications network options and value
    our consultative, direct sales approach.

    PROVIDING COMPLETE SERVICE PACKAGES THAT ARE TAILORED TO OUR CUSTOMERS

    Our service offerings are specifically designed for the needs of our target
    customers. We provide simplified, feature-rich packages of services,
    superior value and a single source for all of our customers' networking
    requirements, all conveniently billed on a single invoice. Our service
    offerings include features offered in packages that we believe are not
    generally available from other providers. Our packages are priced to offer
    savings of 10% to 40% from comparable services provided by the incumbent
    telephone company. Our direct sales representatives consult with our
    customers in person and assist them in selecting service packages
    appropriate for their needs.

    CREATING A STRONG BRAND PRESENCE

    We have quickly achieved a high level of brand awareness in our markets
    through an aggressive multi-media advertising campaign targeted at the
    incumbent telephone company. Our marketing efforts include billboard, radio
    and print advertising, as well as sponsorship of major local events,
    affiliations with local organizations and direct mailings. We believe we
    have been able to achieve a higher level of brand awareness in our markets
    than any other new market entrants. We plan to use our proven marketing and
    advertising strategy to help us achieve rapid and deep penetration in each
    new market we enter.

    DEPLOYING A DIRECT SALES FORCE IN EACH OF OUR MARKETS

    We deploy a large locally-based sales force focused on achieving a
    significant market share in each of our markets. We believe that our
    extensively marketed brand name, visible local presence, readily available
    services and emphasis on personal customer service have enabled our
    170-person sales force to achieve high levels of productivity and quickly
    penetrate new markets.

                                       32
<PAGE>
    INVESTING IN INDUSTRY-LEADING, SCALABLE BACK OFFICE SYSTEMS

    We believe our state-of-the-art billing and operating systems are capable of
    supporting a significant number of lines. These systems, which include
    Saville Convergent Billing Platform-TM-, MetaSolv Telecom Business
    Solution-TM- and Harris Network Management-TM-, have already withstood the
    test of high volumes and rapid growth within our operation. Over the past
    year, we have expanded our provisioning capacity from 3,000 lines per month
    to nearly 15,000 lines per month and believe that our existing
    infrastructure can support continued capacity increases.

    MAINTAINING MAXIMUM NETWORK FLEXIBILITY

    - INTEGRATING DATA AND VOICE NETWORK SERVICES. By integrating both data and
      voice services, we believe we will be able to deliver a broadband digital
      subscriber line connection to a significant percentage of our customers.
      We believe this integration will yield bandwidth flexibility to our
      customers and the strategic advantage of an improved product with reduced
      monthly costs.

    - CAPITALIZING ON OUR UNBUNDLED NETWORK ELEMENT PLATFORM. We provide service
      to a majority of our customers by leasing substantially all of the
      unbundled network elements from the incumbent telephone company and using
      our advanced back office systems to combine these elements into integrated
      Birch-branded voice services. This platform has allowed us to offer voice
      services to customers located virtually anywhere in our markets and
      achieve high gross margins and superior returns on incremental capital
      invested. UNE-P allows us to minimize current capital expenditures and
      maintain design flexibility for the next generation of telecommunications
      technology.

    - POSITIONING FOR MASS DEPLOYMENT OF BROADBAND. Our network objective is to
      mass-deploy broadband facilities (primarily digital subscriber lines) that
      support both voice and data over a single line. We are implementing
      collocations at central offices of the incumbent telephone company
      throughout our markets and intend to deploy packet switches that can
      handle voice and data over a single line as soon as they become available.

    EXPANDING OUR GEOGRAPHIC REACH

    We currently serve 17 markets that have populations ranging in size from
    95,000 to 4.5 million, and we intend to offer our services in 20 additional
    markets before the end of 2001. We expect to expand our operations in Texas
    and into Oklahoma in the second quarter of this year and to commence service
    in the regions served by Ameritech and BellSouth in 2001. We have developed
    systems, network capabilities and an experienced sales force and customer
    service team that position us to rapidly penetrate these new markets and
    regions.

    GROWING THROUGH ACQUISITIONS

    We have completed six acquisitions since our inception in December 1996 for
    total consideration of $27.7 million. From time to time, we consider making
    additional acquisitions to further complement our service capabilities or
    expand our geographic scope. We believe we have been highly successful in
    integrating our acquisitions. With our diverse sources of capital and highly
    sophisticated stockholders and board members, we believe we are well
    positioned to continue to evaluate a variety of these opportunities and make
    selected acquisitions where appropriate.

TELECOMMUNICATIONS SERVICES

    OFFERED SERVICES

    We design our voice and data services to appeal to small and mid-sized
businesses that value simple integrated communications service packages from a
single provider. We believe that the key to attracting and retaining our target
customers is to offer a comprehensive set of services. These services include
voice offerings of local lines, features and long distance at flat per-minute
rates, and data

                                       33
<PAGE>
offerings including dedicated digital subscriber line and dial-up Internet
access, web hosting and other data services.

    We divide our service offerings generally into three broad categories:
voice, Internet and web hosting. The chart below sets forth the different
service packages and options provided within each of these categories.

    DELIVERY OF SERVICES

    UNE-P

    We lease all of the unbundled network elements necessary to provide service
from the incumbent local exchange carriers. We believe that our UNE-P strategy
allows us to enter into new markets more quickly than if we had initially
deployed our own network facilities. This strategy also reduces initial capital
requirements in each market, allowing us to focus our capital resources
initially on the critical areas of sales, marketing and operations support
systems. In addition, we believe UNE-P will allow us to avoid further deploying
circuit switches and maintain design flexibility for the next generation of
telecommunications technology.

    BROADBAND

    We intend to install digital subscriber line equipment at our collocation
sites, at our switch sites and at our customers' locations. We believe this
equipment will allow us to deliver multiple voice calls and data traffic over a
single, standard telephone line and is expected to provide us with substantial
cost savings. Using DSL technology, we believe we will increase the amount of
information we carry on a standard telephone line, which we refer to as
bandwidth, to up to 1.5 million bits per second. The bandwidth is the equivalent
of 24 regular voice telephone lines. Our digital subscriber line equipment will
be programmed to allocate the available bandwidth.

    We believe this technology will reduce our costs since we will lease a
reduced number of standard telephone lines per customer from the incumbent
carrier. For example, if a customer today has eight voice lines, we must order
from and provision through the incumbent carrier eight individual standard
telephone lines. If the same customer were to buy our service which uses digital
subscriber line technology, we would only order and provision one standard
telephone line from the incumbent carrier. Also, we expect that future products
and services designed to take advantage of the increased bandwidth provided by
digital subscriber line technology will allow us to generate incremental revenue
with attractive margins.

    CUSTOMER PREMISES EQUIPMENT

    We offer our customers equipment that they need to run their internal phone
systems, including data routers and wiring, telephone equipment and integrated
access devices. We also sell and service standard key systems, private branch
exchanges and voice-mail systems, and provide inside-wire services for
commercial accounts, including wiring for data networking, in Kansas and
Missouri. We are an authorized equipment distributor for Northern
Telecom, Inc., Toshiba America Information Systems, Inc., NEC America, Inc.,
Executone Information Systems, Inc. and Tadiran Electronic Industries, Inc.

SALES AND MARKETING

    SALES

    As of March 23, 2000, we had a direct sales force of 170 representatives
operating from 23 offices throughout Missouri, Kansas and Texas. Of these
representatives, 28 were primarily selling customer premises equipment and the
remaining 142 were selling local, long-distance, data and Internet services. The
sales representatives are supported by sales managers. Over the next 12 months,
we plan to increase our sales staff in existing markets and open additional
sales offices in Texas and Oklahoma and in Ameritech's and BellSouth's regions.
We supplement our sales efforts through brand awareness efforts including local
and regional advertising, public relations and local sponsorships.

    We seek to convert small to mid-sized business customers from the incumbent
provider of telecommunications services in their market and to establish a
solid, long-term relationship with them.

                                       35
<PAGE>
Our sales representatives meet with prospective customers to gain a thorough
understanding of their business and telecommunications requirements. Sales
representatives then suggest alternatives for operation enhancements and cost
savings based on our service packages.

    We compensate our sales representatives with a competitive base salary,
stock options and commissions based on sales results. We use a revenue-based
commission structure that enables us to attract productive sales people
experienced in disciplined, activity-based sales. This commission structure is
based on incremental revenue and is not subject to a cap.

    We do not actively market to residential customers. Nonetheless, we have
found that our sales and promotional efforts attract residential customers, many
of whom are owners or employees of businesses using our telecommunication
services. Residential customers call our customer service center to receive
forms to apply for service. We do not pay sales commissions for residential
sales.

    ADVERTISING AND PROMOTION

    We conduct extensive marketing campaigns in our local markets. We make use
of advertising and public relations to attract small to mid-sized business
customers and contrast our service attributes with Southwestern Bell's. Our
marketing campaign includes billboard, radio and print advertising, as well as
sponsorship of major local events, affiliations with local organizations and
direct mailings and focuses on public relations. We also believe that our
willingness to serve residential customers--unlike many other competitive local
exchange carriers--creates greater interest in our development among the news
media and general public. In the past, our market launches have attracted
extensive local media coverage.

    In keeping with our philosophy of being accessible to our customers, we
establish local sales and customer service offices in most of the cities and
towns that we serve. In many of these cities and towns, we are the only provider
of local telephone service that maintains an office. Our offices are open to
walk-in traffic and often are located in high-profile areas.

    Because we are able to deliver a comprehensive set of products to our target
customers, we believe we have strong customer loyalty. Our customer churn rates
have generally been less than 1.5% per month.

    PRICING

    We do not intend to position ourselves as the cheapest provider of services,
especially long distance services. We target customers who value the convenience
of our service offerings and personalized customer service. Customers who have
the highest price sensitivity are likely to move frequently among providers,
driving up churn rates. However, we do set our pricing so that our local
business customers can generally save from 10% to 40% on the incumbent
provider's rates. Internet, long distance and customer premises equipment are
generally priced at rates competitive with that of other service providers.

BACK OFFICE SYSTEMS

    Back office systems refer to the hardware and software systems that support
the primary functions of our operations, including:

    - order entry and provisioning;

    - billing;

    - data center;

    - trouble management; and

    - sales support.

    Our goal is to have a back office that allows us to convert our customers'
service from their current local providers to our networks easily and quickly.
Over time, we strive to have "flow through" provisioning capabilities, allowing
services to be implemented through a single systems interface that updates all
ordering, inventory, billing and monitoring systems.

                                       37

    We have implemented the primary elements of our back office, including order
entry, provisioning, billing and network management. We believe we have selected
the best application for each function. The following table describes our key
back office systems that provide crucial operational functionality, their
purpose and timeline for implementation.

</TABLE>

    ORDER ENTRY AND PROVISIONING

    Order entry involves the initial loading of customer data into our
information systems. Currently, our sales executives take orders and our
customer care and provisioning representatives load the initial customer
information into our Saville billing system and our MetaSolv provisioning
system. We intend to increase the efficiency and data accuracy of these
provisioning activities by implementing a sales force automation system to be
combined with Saville CBP and MetaSolv TBS through application integration
middleware. This system will facilitate entry of sales orders from the sales
offices and transmit relevant account and order information to Saville CBP and
MetaSolv TBS. Implementing this system will eliminate several manual steps in
the provisioning process.

    We use the MetaSolv TBS-TM- system to manage and track the timely completion
of each step in the provisioning process. When MetaSolv is coupled with
capabilities of the DSET electronic bonding system, we believe we will be able
to submit orders to external business partners, including Southwestern Bell,
electronically, thereby minimizing implementation time, coordination
complexities and installation costs. Currently, we provision orders
electronically through Southwestern Bell's electronic provisioning system, or
Verigate.

    In addition to the cost benefits associated with the electronic installation
of access lines and inventory management system, the MetaSolv system improves
our internal processes in various other ways, including:

    - directing electronic customer orders to the appropriate employee,
      prompting them to complete required provisioning tasks, including network
      component assignments and management of outside vendor activities; and

                                       38
<PAGE>
    - tracking order progress and alerting operations personnel of steps
      required to fulfill orders within standard work intervals.

    The MetaSolv TBS system enables a customer care coordinator to keep an
installation on schedule and notify the customer of any potential delays. Once
an order has been completed, we update our billing system to initiate billing of
installed services.

    BILLING

    The Saville billing system provides our customers with a consolidated
invoice for all of our services. Customer calls generate billing records that
are transmitted from the call records to the Saville billing system. These
records are then processed by the billing software, which calculates usage
costs, integrates fixed monthly charges, calculates taxation and provides the
data necessary to create a simple customer invoice. We provide invoice
information to a third party printer, which prepares and distributes bills to
our customers. Our customers pay us directly.

    This Saville system allows us to add advanced features such as special
discounts based on call volume, or number of services used, complex local
taxation and discrete billing options by type of service ordered. We believe
these features are exceptionally important given our sophisticated client base.

    TROUBLE MANAGEMENT

    We use MetaSolv TBS-TM-, a customer care and trouble management system, to
provide high quality customer service. Our trouble management system is
integrated into the operational support system. It enables our customer care
personnel to track customer problems proactively, assign repair work to the
appropriate technical teams and provide employees and management access to
comprehensive reports on the status of service activity.

    NETWORK MANAGEMENT

    We use the Harris Network Management system to continuously monitor and
operate our switch networks. The information provided by the Harris system
allows our network operations staff to quickly repair problems in the networks,
thereby eliminating or minimizing impacts to our customers.

    SOUTHWESTERN BELL VERIGATE

    Verigate is the Southwestern Bell end-user interface system that allows our
customer service, trouble management and service provisioning representatives to
access the Southwestern Bell operating systems. Verigate allows us to send local
service requests to receive order commitments back from, reserve new telephone
numbers with, view an order's status at, and test or report customer problems to
Southwestern Bell.

    DATA CENTER

    During the second quarter 2000, we plan to occupy an 8,000 square foot data
center in Kansas City, Missouri. We believe this center has sufficient space to
support significant increases in our access lines, customers and employees.

NETWORK FACILITIES

    LEASED FACILITIES

    During 1999, we began to lease substantially all of the network elements
from Southwestern Bell and combine these elements into integrated Birch-branded
voice services without deploying a switch. By

                                       39
<PAGE>
using UNE-P, we are able to offer our services to a broader geographical area
than we can by using our own switches. Many of our competitors are limited to
serving customers that are located near their facilities. UNE-P allows us to
serve many customers in disparate geographic areas.

    Where we have installed switches, we lease transmission facilities from
Southwestern Bell to connect our switches to our collocated equipment in
Southwestern Bell's central offices and to unbundled loops. Given the current
capacity of existing local networks, we do not anticipate having to build local
transmission facilities in the future. Similarly, we believe that the capacity
of existing long-distance networks renders direct ownership of long distance
transmission facilities unnecessary.

    Leasing, rather than building, facilities supports our strategy of rapid
local market development because our sales activity is not constrained by
network expenditures. Moreover, by leasing transmission facilities, we can offer
our services throughout a metropolitan area and we are not constrained by the
limited number of locations in which we could build transmission facilities.

    OWNED FACILITIES

    We deploy data transmission packet switches in most of our markets. We use
these packet switches to transmit data over our leased transmission lines and
plan to use these packet switches to transmit our long distance voice traffic
once our conversion plan is implemented.

    We currently operate local/long distance circuit switches in Kansas City and
St. Louis, Missouri and Wichita, Kansas. We do not intend to deploy more circuit
switches because we believe voice-capable packet switches will be more
economical to operate in the future. Additionally, we collocate our electronic
equipment at Southwestern Bell's central offices to support future digital
subscriber line services and existing circuit switches. Collocation allows us to
connect to transmission lines we lease from Southwestern Bell.

    At the customer's premises, we connect unbundled loops directly to
customer-owned equipment. We may also deploy electronic equipment (intelligent
channel banks or access servers) that concentrate data and voice traffic. This
enables us to obtain higher capacity from the transmission line of the incumbent
local exchange carrier.

OPERATIONS

    EMPORIA AND KANSAS CITY SERVICE CENTERS

    Our service centers in Emporia, Kansas and Kansas City, Missouri are
critical to our ability to offer excellent service and to support growth. These
service centers process orders, interface with Southwestern Bell's operational
support systems and provide customer service, trouble resolution, billing and
collection services for our customers. These service centers provide rapid,
human assistance rather than the automated, cumbersome customer interface
currently used by many telecommunications providers.

    FIELD TECHNICAL OPERATIONS

    Our field technicians service our facilities and customer-owned facilities.
These technicians install, repair and maintain digital switches, transmission
equipment, private branch exchanges, key systems, data equipment and inside
wiring, including wiring for data networking. We believe field technicians are
often the most respected source of telecommunications advice for small and
mid-sized business customers. We believe that having a skilled, in-demand group
of technicians supports our customer base, provides expertise for data
deployment and strengthens customer loyalty.

                                       40
<PAGE>
COMPETITION

    The telecommunications industry is highly competitive. We believe we compete
principally on the basis of customer service, accurate billing, variety of
services and, to a lesser extent, pricing levels and less complex pricing
structures. Our ability to compete effectively depends upon our continued
ability to maintain high quality, market-driven services at prices generally
equal to or below those charged by competitors. To maintain our competitive
posture, we believe that we must be able to provide high quality integrated
communications services and be positioned to reduce our prices in response to
potential competition. Any of these reductions could adversely affect us. Many
of our current and potential competitors have financial, technical, marketing,
personnel and other resources, including brand name recognition, substantially
greater than ours, as well as other competitive advantages over us.

    INCUMBENT TELEPHONE COMPANIES

    In our existing markets, we compete principally with Southwestern Bell. As a
recent entrant in the telecommunications services industry, we may not achieve a
significant market share for any of our services in our markets. In particular,
Southwestern Bell and other local telephone companies have long-standing
relationships with their customers, have financial, technical and marketing
resources substantially greater than ours, have the potential to subsidize
competitive services with revenue from a variety of businesses and currently
benefit from existing regulations that favor these incumbent local exchange
carriers over us in some respects. While recent regulatory initiatives, which
allow competitive local exchange carriers such as us to interconnect with
incumbent local exchange carrier facilities, provide increased business
opportunities for us, these interconnection opportunities have been, and likely
will continue to be, accompanied by increased pricing flexibility for and
relaxation of regulatory oversight of the incumbent local exchange carriers.
Future regulatory decisions could grant incumbent local exchange carriers
increased pricing flexibility or other regulatory relief. These initiatives
could also have a material adverse effect on us.

    COMPETITIVE LOCAL EXCHANGE CARRIERS/INTEREXCHANGE CARRIERS/OTHER MARKET
     ENTRANTS

    We also face competition from other current and potential market entrants.
These market entrants include long distance carriers that compete with our long
distance services and seek to enter, reenter or expand into the local exchange
market. AT&T, GTE, MCI WorldCom and Sprint are among these carriers. Competitive
local exchange carriers, resellers of local exchange services, competitive
access providers, cable television companies, electric utilities, microwave
carriers, wireless telephone system operators and private networks built by
large end users also compete with us. In addition, consolidation and strategic
alliances within the telecommunications industry, or the development of new
technologies could put us at a competitive disadvantage. Not only does the
Telecommunications Act impose regulatory requirements on all local
telecomunications service providers, but it also grants the FCC expanded
authority to reduce the level of regulation applicable to any telecommunications
service provider, including any incumbent telecommunications service providers.
The manner in which these provisions of the Telecommunications Act are
implemented and enforced could have a material adverse effect on our ability to
compete successfully against incumbent local exchange carriers and other
telecommunications service providers.

    The changes in the Telecommunications Act radically altered the market
opportunity for new telecommunications service providers. Because the
Telecommunications Act requires local exchange carriers to unbundle their
networks, new telecommunications service providers are able to rapidly enter the
market by installing switches and leasing trunk and loop capacity. Newer
providers, like us and some competitors that we may encounter in some of our
markets, will not have to replicate existing facilities until traffic volume
justifies building them, and can be more opportunistic in designing and
implementing networks.

                                       41
<PAGE>
    In addition to the new telecommunications service providers, interexchange
carriers and other competitors listed above, we may face competition from other
market entrants such as electric utilities, cable television companies and
wireless companies. Electric utilities have existing assets and low cost access
to capital which could allow them to enter a market rapidly and accelerate
network development. Cable television companies are entering the
telecommunications market by upgrading their networks with fiber optics and
installing facilities to provide fully interactive transmission of broadband
voice, video and data communications. Finally, wireless companies intend to
develop wireless technology for deployment in the United States as a broadband
substitute for traditional wireline local telephones. Some Internet companies
are also developing applications to deliver switched voice communications over
the Internet.

    LONG DISTANCE SERVICES

    The long distance telecommunications industry has numerous entities
competing for the same customers and a high churn rate, as customers frequently
change long distance providers in response to offerings of lower rates or
promotional incentives. Prices in the long distance market have declined
significantly in recent years and are expected to continue to decline. Our
primary competitors are the major interexchange carriers and resellers of long
distance services. We believe that pricing levels are a principal competitive
factor in providing long distance service; however, we seek to avoid direct
price competition by packaging long distance service, local service, customer
premises equipment and Internet access service together with a simple pricing
plan.

    CUSTOMER PREMISES EQUIPMENT

    We compete with numerous equipment vendors and installers and
telecommunications management companies for the sale of customer premises
equipment and related services. We generally offer our products at prices
consistent with other providers and differentiate our service through our
product packages.

    DATA/INTERNET SERVICES

    The Internet services market is highly competitive, and we expect that
competition will continue to intensify. Internet service, meaning both Internet
access and on-line content services, is provided by Internet service providers,
satellite-based companies, long distance carriers and cable television
companies. Many of these companies provide direct access to the Internet and a
variety of supporting services to businesses and individuals. In addition, many
of these companies, such as America Online, Inc., MSN, Prodigy Services Company
and WebTV Networks, offer on-line content services consisting of access to
closed, proprietary information networks. Long distance companies, among others,
are aggressively entering the Internet access markets. Long distance carriers
have substantial transmission capabilities, traditionally carry data to large
numbers of customers and have an established billing system infrastructure that
permits them to add new services. Satellite companies are offering broadband
access to the Internet from desktop PCs. Cable companies are starting to provide
Internet services using cable modems to customers in major markets. Many of
these competitors have substantially greater financial, technological,
marketing, personnel, name-brand recognition and other resources than those
available to us.

EMPLOYEES

    At December 31, 1999, we employed 935 persons. Additionally, we occasionally
hire temporary employees. We are not party to any collective bargaining
arrangements and believe that our relationship with our employees is good.

                                       42
<PAGE>
PROPERTIES

    We lease 43,783 square feet in office space in Kansas City, Missouri for our
corporate headquarters. This lease expires December 2006. Recently, we leased an
additional 64,546 square feet of office space in Kansas City to expand our
corporate headquarters. This lease expires February 2008. In Emporia, Kansas, we
own two buildings totaling 58,500 square feet for our customer care center and
provisioning divisions. In addition, we lease an aggregate of 21,175 square feet
to house our switches in Kansas City and St. Louis, Missouri and Wichita,
Kansas. These leases expire March 2003, November 2008, August 2005 and June
2008, respectively. We also lease space in 27 buildings, totaling approximately
110,823 square feet, in Missouri, Kansas, Texas and Oklahoma for our sales
offices and customer premises equipment sites. These leases are generally leased
on a month-to-month or annual basis.

LEGAL PROCEEDINGS

    From time to time, we may be involved in claims or litigation that arise in
the normal course of business. We are not a party to any legal proceedings
which, if decided adversely, would have a material adverse effect on our
business or financial condition or results of operations.

<PAGE>
                                   REGULATION

REGULATORY OVERVIEW

    We are subject to regulation by federal, state and local government
agencies. Historically, the FCC had jurisdiction over interstate long distance
services and international services, while state regulatory commissions had
jurisdiction over local and intrastate long distance services.

    In 1996, Congress passed the Telecommunications Act of 1996, opening the
local market to competition and allowing the Bell operating companies to compete
for the first time in the long distance market within their local service
regions once specified conditions were met. The Telecommunications Act
fundamentally changed the way telecommunications is regulated in this country.
The FCC was given a major role in writing and enforcing the rules under which
new competitors could compete in the local marketplace. Those rules, coupled
with additional rules and decisions promulgated by the various state regulatory
commissions, form the core of the regulatory framework under which we operate in
providing local exchange service.

    With a few limited exceptions, the FCC continues to retain exclusive
jurisdiction over our provision of interstate and international long distance
service, and the state regulatory commissions regulate our provision of
intrastate local and long distance service. Additionally, municipalities and
other local government agencies may regulate limited aspects of our business,
such as use of government-owned rights-of-way, and may require permits such as
zoning approvals and building permits.

    In the aftermath of the Telecommunications Act, the regulation of the
telecommunications industry has been in a state of flux. The FCC and state
regulatory commissions have adopted many new rules to implement this legislation
and encourage competition, but that implementation is ongoing. The following
summary of regulatory developments does not purport to describe all current and
proposed federal, state and local regulations and legislation affecting the
telecommunications industry. Many of these are currently the subject of judicial
proceedings, legislative hearings and administrative proposals, any of which
could change, in varying degrees, the manner in which this industry operates. We
cannot predict at this time the outcome of these proceedings or their impact
upon the telecommunications industry or on us.

THE TELECOMMUNICATIONS ACT

THE TELECOMMUNICATIONS ACT'S LOCAL COMPETITION FRAMEWORK

    One of the key goals of the Telecommunications Act is to encourage
competition in local telephone service. To do this, the Telecommunications Act
provides three means by which telecommunications service providers can enter the
local phone service marketplace. The three modes of entry are as follows:

    - RESALE.  Incumbent telephone companies are required to permit new
      telecommunications service providers to purchase their services for resale
      to the public at a wholesale rate that is less than the rate charged by
      the incumbent telephone companies to their retail customers.

    - ACCESS TO NETWORK ELEMENTS.  Incumbent telephone companies are required to
      lease to new telecommunications service providers the various elements in
      their network that are used to provide local telephone service. The leased
      parts of the incumbent telephone companies' networks are known as
      unbundled network elements. The incumbent telephone companies must make
      unbundled network elements available at rates that are based on their
      forward-looking economic costs.

    - CONSTRUCTION OF NEW FACILITIES.  New telecommunications service providers
      may also enter the local phone service market by building entirely new
      facilities. The incumbent telephone companies are required to allow new
      telecommunications service providers to interconnect their

                                       44
<PAGE>
      facilities with the incumbent telephone company's, so each carrier's
      customers can reach the other's.

    To facilitate new telecommunications service providers' entry into local
telephone markets using one or more or some combination of these three methods,
the Telecommunications Act imposes on incumbent telephone companies the
obligation to open their networks and markets to competition. When requested by
competitors, incumbent telephone companies are required to negotiate, in good
faith, agreements that lay out terms governing the interconnection of their
network, access to unbundled network elements and resale. Incumbent telephone
companies must also allow competing carriers to "collocate," or place their own
equipment in incumbents' central offices.

    In addition, all local exchange carriers, including both incumbent and new
telecommunications service providers, are subject to the following requirements:

    - INTERCONNECTION.  All local telecommunications service providers must
      permit their competitors to interconnect with their facilities either
      directly or indirectly. Incumbent telephone companies are additionally
      obligated to permit interconnection at any technically feasible point
      within their networks, on nondiscriminatory terms, at prices based on cost
      (which may include a reasonable profit);

    - NUMBER PORTABILITY.  All local telecommunications service providers must
      implement number portability technology that allows a customer to retain
      its existing phone number if it switches from one local exchange carrier
      to a competitor. This technology primarily benefits new telecommunications
      service providers, which can gather market share more easily if customers
      can switch to these carriers without changing telephone numbers;

    - RECIPROCAL COMPENSATION.  All local telecommunications service providers
      must complete local calls originated by other telecommunications service
      providers under reciprocal compensation arrangements. That is, the local
      provider terminating a local call is entitled to payment from the local
      provider originating a call. Charges assessed by the incumbent telephone
      company for terminating calls originated on a new telecommunications
      service provider's network must be based on a reasonable approximation of
      additional cost. The FCC recently determined that Internet service
      provider-bound traffic is interstate in nature, not local, and is
      therefore outside the scope of the Telecommunications Act's reciprocal
      compensation provisions. The FCC has initiated a proceeding to determine
      appropriate carrier-to-carrier compensation for Internet service
      provider-bound traffic. At the same time, the FCC has declined to overturn
      a multitude of state decisions requiring incumbent telephone companies to
      pay new telecommunications service providers compensation for delivering
      Internet traffic to Internet service providers that had selected a new
      telecommunications service provider as their local service provider. The
      FCC's decision is on appeal, and incumbent telephone companies are also
      expected to ask states or federal courts to reverse the existing state
      determinations;

    - DIALING PARITY.  Requires all local telecommunications service providers
      to provide nondiscriminatory access to telephone numbers, operator
      services, directory assistance and directory listing with no unreasonable
      dialing delays. Local dialing parity ensures that customers on one local
      exchange carrier do not have to dial extra digits to reach customers on a
      different local or toll carrier's network; and

    - ACCESS TO RIGHTS-OF-WAY.  Requires all local telecommunications service
      providers to permit competing providers access to poles, ducts, conduits
      and rights-of-way at reasonable and nondiscriminatory rates, terms and
      conditions. The FCC has opened a proceeding seeking to define in greater
      detail the scope of the incumbent telephone company's obligation to
      provide access to rights-of-way that it owns or controls, including those
      within its own central offices and other buildings, and buildings owned by
      private third parties.

                                       45
<PAGE>
    Executing an interconnection agreement does not guarantee a new
telecommunications service provider unfettered access to the incumbent telephone
company's market. Interconnection agreements between incumbent telephone
companies and new telecommunications service providers may have short terms,
requiring the new telecommunications service provider to renegotiate the
agreements on a regular basis. Incumbent telephone companies may not provide
timely provisioning or adequate service quality, thereby impairing a new
telecommunications service provider's reputation with customers who can easily
switch back to the incumbent telephone company. In addition, the prices set in
the agreements or through state regulatory commission arbitration proceedings
may be subject to changes mandated by state regulatory commissions as they
develop permanent rules governing interconnection and may not in all instances
be set at levels that allow new telecommunications service providers to compete
effectively.

THE FCC'S RULES IMPLEMENTING THE TELECOMMUNICATIONS ACT'S LOCAL COMPETITION
  PROVISIONS

    In August 1996, the FCC issued an order implementing the local competition
provisions of the Telecommunications Act. The FCC established rules about how
interconnection and collocation were to be provided, put forth a method that
state commissions should use to establish prices for interconnection and
unbundled network elements, and specified which parts of an incumbent's network
must be made available as unbundled network elements to competing carriers. The
FCC also held that incumbent telephone companies must provide new
telecommunications service providers with "combinations" of unbundled network
elements, making it possible for new telecommunications service providers, in
many instances, to provide service to customers by leasing all of the component
unbundled network elements from the incumbent telephone company. This method of
providing service is known as the unbundled network element platform, or UNE-P.
Specifically, among other rules, the FCC established a list of seven network
elements, comprising most of the significant facilities, features,
functionalities or capabilities of the network, that the incumbent telephone
companies must unbundle. In addition, the FCC mandated a particular
forward-looking pricing methodology for these network elements that produces
relatively low element prices that are favorable to competitors.

    After the FCC released its rules, numerous parties challenged the rules
before the U.S. Court of Appeals for the Eighth Circuit. The Eighth Circuit
overturned many of the FCC's rules on the grounds that the agency had exceeded
its authority and misinterpreted the law.

    On January 25, 1999, the United States Supreme Court largely reversed the
Eighth Circuit's decision, holding that the FCC has general jurisdiction to
implement the local competition provisions of the Telecommunications Act and
reestablishing the validity of many of the FCC's interconnection rules. In so
doing, the Supreme Court stated that the FCC has authority to set pricing
guidelines for unbundled network elements, to prevent incumbent telephone
companies from separating existing combinations of network elements, and to
establish "pick and choose" rules regarding interconnection agreements. "Pick
and choose" rules would permit a carrier seeking interconnection to pick and
choose among the terms of service from other interconnection agreements between
the incumbent and various new telecommunications service providers.

    Although it upheld the FCC's jurisdiction to establish unbundled network
element pricing guidelines, the Supreme Court did not evaluate the specific
"forward-looking" pricing methodology adopted by the FCC, and the case has been
remanded to the Eighth Circuit for further consideration of that specific
pricing methodology. Some incumbent telephone companies have argued that this
pricing methodology does not allow adequate compensation for the provision of
unbundled network elements. The Eighth Circuit heard oral arguments on this
pricing issue on September 16, 1999, but has not yet issued a ruling. We cannot
predict the outcome of this proceeding. If the Eighth Circuit fails to uphold
the FCC's forward-looking pricing methodology, it may materially adversely
affect our business.

                                       46
<PAGE>
    Additionally, the Supreme Court vacated the FCC rules defining what network
elements must be unbundled and made available to the new telecommunications
service providers by the incumbents. The Supreme Court held that the FCC must
provide a stronger rationale to support the degree of unbundling ordered.

    On November 5, 1999, in response to the Supreme Court's ruling, the FCC
released new rules specifying which portions of the incumbent telephone
companies' networks must be made available as unbundled network elements. The
FCC reaffirmed that incumbent telephone companies must provide unbundled access
to the following six network elements:

    - loops, including loops used to provide high-capacity and advanced
      telecommunications services such as digital subscriber lines;

    - network interface devices;

    - local circuit switching;

    - dedicated and shared transport;

    - signaling and call-related databases; and

    - operations support systems.

    The FCC removed from the list of unbundled network elements operator service
and directory assistance. The FCC concluded that the market has developed
sufficiently that new telecommunications service providers can and do
self-provide these services, or acquire them from alternative sources. The FCC
also noted that incumbent telephone companies remain obligated under the
non-discrimination requirements of the Communications Act of 1934 to comply with
the reasonable request of a new telecommunications service provider that
purchases these services from the incumbent telephone companies to rebrand or
unbrand those services, and to provide directory assistance listings and updates
in daily electronic batch files. In addition, the competitive checklist
contained in section 271 of the Communications Act of 1934 requires Bell
operating companies to provide nondiscriminatory access to these services.

    The FCC also modified the local switching unbundled network element,
concluding that incumbents need not provide access to unbundled local circuit
switching for customers with four or more lines that are located in the densest
parts of the top 50 metropolitan statistical areas so long as the incumbent
makes available an alternative arrangement for reaching customers, known as the
enhanced extended link. The enhanced extended link allows new telecommunications
service providers to gain access to customers without collocating in every
central office, because it combines the local loop with a multiplexer and
transport to the new telecommunications service provider's local existing
collocated facilities or switch. Notwithstanding the FCC's ruling, unrestricted
access to unbundled switching is available in Texas, where state rulings require
incumbent telephone companies to make switching available as an unbundled
network element.

    In addition to these changes, the FCC also:

    - Limited the scope of the shared transport unbundled network element,
      holding that the incumbent must only offer shared transport as a unbundled
      network element where unbundled local circuit switching is provided.

    - Held that incumbents are not required to offer packet switching as a
      unbundled network element in most cases.

    - Held that both the loop and transport unbundled network elements include
      access to "dark fiber." Dark fiber is distinguished from "lit fiber"
      transmission capacity in that dark fiber is sold independently from the
      electronics necessary to "light" the fiber and transmit information. The

                                       47
<PAGE>
      availability of dark fiber from incumbents as a unbundled network element
      could create an additional source of dark fiber in the market.

    - Ordered "sub-loop unbundling," which will allow new telecommunications
      service providers to connect at any feasible point along the local loop,
      and not just at the central office. In some incumbent networks, subloop
      unbundling will make it easier for new telecommunications service
      providers to use portions of the unbundled network element loop to offer
      advanced services, such as digital subscriber lines. In a separate order,
      the FCC also ordered the unbundling of the "high-frequency" portion of the
      loop, which also makes it easier and less expensive for new
      telecommunications service providers to use unbundled network elements to
      offer advanced services, such as digital subscriber lines.

    The FCC's decision regarding unbundled network elements is currently the
subject of petitions for reconsideration filed at the FCC by various parties,
including us. Some incumbent telephone companies have asked the FCC to expand
the limitation on switching by, among other things, extending its geographic
scope. We and other new telecommunications service providers have asked the FCC
to either do away with the limitation or make it applicable to only larger
customers. We cannot predict the outcome of this proceeding. If the FCC further
restricts the availability of unbundled switching, it could adversely affect our
ability to serve customers efficiently.

    Another open question is whether incumbent telephone companies are required
to combine network elements not currently combined in their networks for
requesting new telecommunications service providers. The FCC's rules requiring
the incumbent telephone companies to do so were vacated by the Eighth Circuit,
but the FCC and the new telecommunications service provider industry have asked
that court to reinstate the rules in the wake of the Supreme Court's decision.
If the rules are reinstated, it will significantly expand the ability of new
telecommunications service providers to provide service to customers using
network elements purchased from the incumbent telephone companies. Also
unsettled is the scope of the FCC's rule requiring incumbent telephone companies
to provide requesting new telecommunications service providers with combinations
of network elements that are "currently combined" in the incumbent telephone
company's network. The new telecommunications service provider industry has
taken a broad view of this requirement, interpreting it to mean that new
telecommunications service providers are entitled to purchase network element
combinations so long as they are combined anywhere in the incumbent telephone
company's network. The incumbent telephone companies, by contrast, have taken a
much narrower view, arguing that the rule requires the incumbent telephone
companies only to provide combinations of network elements that are currently in
service to a particular customer. The ultimate resolution of this question could
expand or restrict our ability to provide service to our customers using network
elements purchased from the incumbent telephone company.

    The Eighth Circuit is expected to rule on the pricing issue in the next
several months and may also rule on the incumbent telephone companies'
obligation to provide new network element combinations in the same decision. It
is not clear when the FCC or the courts will act to define the scope of
"currently combined." The possible impact of the resolution of these open issues
on existing interconnection agreements between incumbent telephone companies and
new telecommunications service providers or on agreements that may be negotiated
in the future cannot be determined at this time.

    In addition to its rulings regarding interconnection and unbundled network
elements, the FCC has issued a series of orders on the ability of new
telecommunications service providers to provide digital subscriber lines and
other high-bandwidth services to their customers for, among other things,
Internet access. Those orders have made clear that new telecommunications
service providers are entitled to collocate the equipment necessary to provide
those services in incumbent telephone companies' central offices; that incumbent
telephone companies must, where technically feasible, provide new

                                       48
<PAGE>
telecommunications service providers with high-quality loops capable of
supporting digital subscriber lines and that the incumbent telephone companies
must provide new telecommunications service providers with information
concerning the make-up of their networks to allow the new telecommunications
service provider to determine if a particular customer can be served with
digital subscriber line service. However, many of the details of the orders'
implementation are unsettled and we cannot assure you that the rules are
sufficient to ensure that the incumbent telephone companies meet their
obligations.

THE STATES' ROLE IN IMPLEMENTING THE LOCAL COMPETITION PROVISIONS

    Although the FCC establishes nationwide guidelines governing entry by new
telecommunications service providers under the Telecommunications Act, state
regulatory commissions also have major roles in implementing the local
competition provisions of the act. Among other things, state regulatory
commissions must approve or reject interconnection agreements, and they have
chief responsibility for arbitrating and mediating these agreements if the
negotiating carriers cannot reach an understanding on the agreement's terms.
State regulatory commissions are also charged with developing and implementing
cost-based prices for interconnection and unbundled network elements, in
accordance with the Telecommunications Act and the forward-looking pricing
guidelines set by the FCC. State regulatory commissions are also permitted to
establish additional unbundled network elements consistent with federal law and
policy.

BELL OPERATING COMPANIES ENTRY INTO LONG DISTANCE

    The Telecommunications Act also seeks to encourage local competition by
requiring the regional Bell operating companies to demonstrate on a
state-by-state basis that they have adequately opened their network and market
to competitors before they can provide long distance service to end users in
their own local service areas. Specifically, the Telecommunications Act lays out
a 14-point checklist which generally requires a regional Bell operating company
to prove to the FCC that it has complied with the interconnection and network
access obligations discussed above and that it faces effective competition in
the state where it seeks to provide long distance service. While the FCC has
ultimate responsibility for deciding whether the checklist conditions have been
met, the FCC is required to first consult with the appropriate state regulatory
commission.

    Southwestern Bell is in the process of applying for authority to provide
long distance service in Texas. The FCC is expected to rule on Southwestern
Bell's application in April 2000. Southwestern Bell has also begun the process
of applying for long distance authority in Kansas by making a preliminary filing
with the Kansas state regulatory commission. If Southwestern Bell receives
approval from the FCC as described above, Southwestern Bell will be able to
provide in-region long distance services, which will enable it to provide
customers with a full range of local and long distance telecommunications
services. The ability of Southwestern Bell to provide long distance services is
expected to be an additional source of competition for us.

OTHER FEDERAL REGULATION

    The FCC regulates our interstate and international service offerings. Those
services include our provision of interstate and international long distance
service and our provision of interstate access service. The FCC has established
different levels of regulation for dominant carriers and non-dominant carriers.
Incumbent telephone companies, such as the Bell operating companies and GTE, are
currently considered dominant carriers, and are subject to extensive rate and
operational regulation, while new telecommunications service providers such as
we are considered non-dominant carriers, and are subject to substantially less
regulation.

                                       49
<PAGE>
INTERSTATE AND INTERNATIONAL LONG DISTANCE SERVICES

    Interstate and international long distance services of non-dominant carriers
are subject to relatively little regulation by the FCC. Our provision of
international long distance services requires prior authorization by the FCC
under Section 214 of the Telecommunications Act, which we have obtained. We are
also required to file tariffs with the FCC for international long distance
service on an ongoing basis.

    Under the FCC's streamlined regulation of non-dominant carriers, we may
install and operate facilities for the transmission of domestic interstate
communications without prior FCC authorization.

    In addition, in October 1996, the FCC adopted an order in which it
eliminated the requirements that non-dominant interstate interexchange carriers
maintain tariffs on file with the FCC for domestic interstate services. The
order does not apply to the switched and special access services of the Bell
operating companies or other local exchange carriers. The FCC order was issued
under authority granted to the FCC in the 1996 Act to "forbear" from regulating
any telecommunications services provider under some circumstances. After a
nine-month transition period, relationships between interstate carriers and
their customers would be set by contract. At that point, long distance companies
would be prohibited from filing tariffs with the FCC for interstate, domestic,
interexchange services. Several parties filed notices for reconsideration of the
FCC order and other parties appealed the decision. On February 13, 1997, the
United States Court of Appeals for the District of Columbia Circuit stayed the
implementation of the FCC order pending its review of the order on its merits.
Currently, that stay remains in effect and interstate long distance telephony
companies are therefore still required to file tariffs.

    The D.C. Circuit heard oral argument on the merits of the FCC's detariffing
order on March 14, 2000, but has not yet issued an order. If the stay is lifted
and the FCC order becomes effective, telecommunications carriers will no longer
be able to rely on the filing of tariffs with the FCC as a means of providing
notice to customers of prices, terms and conditions on which they offer their
interstate services. The FCC has required that non-dominant interexchange
carriers post their rates, terms and conditions for all their interstate,
domestic services on their Internet web sites if they have one; this rule is
effective once the FCC's mandatory detariffing order takes effect. This may
result in significant administrative expenses for us. The obligation to provide
non-discriminatory, just and reasonable prices remains unchanged under the
Communications Act of 1934. Tariffs also allow a carrier to limit its liability
to its customers, including in connection with service interruptions. If tariffs
are eliminated, we may become liable for costs that we would have been able to
limit through tariff filings, and we cannot assure you that the potential
liabilities will not have a material adverse effect on our results of operations
and financial condition.

ACCESS SERVICES

    Unlike dominant carriers, which are subject to extensive rate regulation, we
and other non-dominant carriers are subject to relatively little regulation of
our interstate access services. The FCC has eliminated the requirement that
non-dominant carriers must file tariffs for their access services. While no
longer mandatory, carriers may continue to file access tariffs. We have chosen
to continue to do so.

    In August 1999, the FCC granted incumbent telephone companies subject to
price cap rate regulation, including the regional Bell operating companies,
substantial pricing flexibility with regard to some interstate access services.
Among other things, the FCC's new rules permit incumbent telephone companies,
upon a showing that the services in question are subject to sufficient levels of
competition, to offer volume and term discounts and contract tariffs for
particular access services. The new rules also allow incumbent telephone
companies, upon meeting a higher competitive standard, to file tariffs for their
access services free from many rate structure requirements. To the extent these
regulatory

                                       50
<PAGE>
initiatives enable or require incumbent telephone companies to offer selectively
reduced rates for some access services, the rates we may charge for these access
services will likely be constrained. In addition, the FCC has recently initiated
a proceeding to examine whether to regulate the rates that new
telecommunications service providers charge for their access services. While the
FCC has received considerable opposition from the new telecommunications service
provider industry and others to doing so, we cannot assure you that the FCC will
not adopt some form of regulation for new telecommunications service provider
access charges. The timing of the FCC's decision is uncertain.

    In addition to the pricing flexibility described above, the FCC is currently
considering a joint proposal from AT&T, Bell Atlantic, BellSouth, GTE, SBC
Communications and Sprint to lower significantly and deaverage interstate access
charges for participating price cap local exchange carriers. The FCC could issue
an order on this proposal in the first half of 2000. If adopted, these pricing
reforms could increase competition among carriers offering local exchange and
exchange access service in our operating area.

ADDITIONAL FEDERAL ISSUES

    ACCESS TO POLES, DUCTS, CONDUITS AND RIGHTS-OF-WAY.  An area of the law that
remains in flux concerns the extent of a carrier's obligations to provide access
to poles, ducts, conduits and rights-of-way. We are obligated under Section 224
of the Communications Act to permit other carriers reasonable access to our
poles, ducts, conduits and rights-of-way and the FCC has adopted comprehensive
rules governing how access is to be provided. The FCC is also currently
considering additional rules, including whether access to rooftops and space
inside buildings, including buildings owned by utilities, should be mandated
under the Telecommunications Act.

    EEO REPORT.  The FCC requires us to file an annual employment report to
comply with the FCC's Equal Employment Opportunity policies.

    TRUTH IN BILLING.  The FCC has adopted new rules designed to make it easier
for customers to understand the bills of telecommunications carriers. These new
rules establish requirements regarding the formatting of bills and the
information that must be included on bills. These rules have been appealed in
federal court.

    ANTI-SLAMMING RULES.  The FCC implemented the so-called "anti-slamming"
rules, which protect consumers whose pre-subscribed carriers have been switched
without their consent. Under the rules, a carrier found to have slammed a
customer is subject to substantial fines and must remove from the consumer's
bill all charges incurred within 30 days of the slamming. While we do not engage
in these practices, a slamming fine, if levied, could have a material impact on
our business in the future.

    CUSTOMER PROPRIETARY NETWORK INFORMATION.  In February 1998, the FCC adopted
rules implementing Section 222 of the Communications Act of 1934, which governs
the use of customer proprietary network information by telecommunications
carriers. Customer proprietary network information generally includes any
information regarding a subscriber's use of a telecommunications service, where
it is obtained by a carrier solely by virtue of the carrier-customer
relationship. The FCC has clarified that customer proprietary network
information does not include a subscriber's name, telephone number, and address,
as this information is generally not derived from the carrier's provision of a
telecommunications service to a customer. Under the FCC's rules, a carrier may
only use a customer's proprietary network information to market services that
are "necessary to, or used in," the provision of a service that the carrier
already provides to the customer, unless it receives the customer's prior oral
or written consent to use that information to market other services. In
December 1999, the Court of Appeals for the Tenth Circuit vacated the FCC's
original and modified customer proprietary network information rules on the
grounds that they violate the First Amendment. However, Section 222 of the
Communications Act remains the law and that section, in addition to the FCC's
now-vacated rules,

                                       51
<PAGE>
provides some guidance on the use of customer proprietary network information
rules. Uncertainty regarding restrictions on the use of customer proprietary
network information rules may impede our ability to market integrated packages
of services effectively and to expand existing customers' use of our services.

    UNIVERSAL SERVICE.  Under the Telecommunications Act of 1996, on May 8,
1997, the FCC released an order establishing a significantly expanded federal
universal service subsidy regime. The universal service program provides support
to carriers serving low-income customers and customers who live in areas where
the cost of providing telecommunications services is high. In addition, the FCC
established new subsidies for telecommunications and some information services
provided to qualifying schools and libraries and for services provided to rural
health care providers. Providers of interstate telecommunications services, as
well as other entities, such as private carriers offering excess capacity to end
user customers, must pay for these programs. Our contribution to the federal
support funds would be calculated based on a percentage of our gross end-user
interstate and international telecommunications revenues. The assessment rate
for the second quarter of 2000 is 5.7101 percent of interstate and international
end-user telecommunications revenues. The contribution factor issued by the FCC
varies quarterly. The amounts contributed may be billed to customers. Currently,
the FCC is calculating assessments based on the prior year's revenues. Assuming
that the FCC continues to calculate contributions based on the prior year's
revenues, we believe that we will not be liable to contribute any material
amount to these programs during 2000 because we had limited interstate and
international end user revenues in 1999. The threshold before we are required to
contribute is a $10,000 contribution, which translates into roughly $175,000 in
interstate end user telecommunications revenues. With respect to subsequent
years, however, we are currently unable to quantify the amount of any
contributions that we will be required to make or the effect that these required
contributions will have on our financial condition.

    The FCC has recently adopted the cost model which it will use to determine
the support needed in high-cost areas and the inputs for the model. The new
high-cost support mechanism, which went into effect on January 1, 2000 for
non-rural carriers, substantially increases the amount of high-cost support
provided to non-rural carriers. The U.S. Court of Appeals for the Fifth Circuit
recently issued an order upholding in part, and reversing in part, the
May 8(th) FCC order implementing these funds. Numerous FCC orders revising these
funds are subject to petitions for reconsideration and further petitions for
appeal. The outcome of these proceedings or their effect cannot be predicted.

    In addition to the universal service mechanisms described above, the FCC is
currently considering a joint proposal from Bell Atlantic, BellSouth, GTE, SBC
Communications, AT&T, and Sprint to create a $650 million fund to provide
universal service support for interstate access charges. If adopted, this
proposal could significantly increase the contribution obligations of other
telecommunications carriers.

    COMMUNICATIONS ASSISTANCE FOR LAW ENFORCEMENT ACT.  Under this act,
telecommunications carriers are required to: (1) provide law enforcement
officials with call content and call identifying information under a valid
electronic surveillance warrant, and (2) reserve a sufficient number of circuits
for use by law enforcement officials in executing court authorized electronic
surveillance. If we provide facilities-based services, we may incur costs in
meeting both of these requirements. In particular, regarding the requirements
related to call content and identification, except in very limited circumstances
the government is required to compensate carriers only for the costs of making
equipment installed or deployed before January 1, 1995 compliant with this act.
While the telecommunications industry is attempting to negotiate legislative and
administrative changes to this reimbursement cut-off date, as it stands today,
we will be financially responsible for ensuring that our post-1995 equipment is
in compliance. Regarding the circuit capacity requirements, the government will
finance any necessary increases in capacity for equipment that we have
specifically identified as installed or deployed prior to September 8, 1998, and
we are responsible for paying only for any necessary increases in capacity for
equipment installed or deployed after that date.

<PAGE>
STATE AND LOCAL REGULATION

    In general, state regulatory commissions have regulatory jurisdiction over
us when our facilities and services are used to provide local and other
intrastate services. Under the Telecommunications Act, state commissions
continue to set the requirements for providers of local and intrastate services,
including quality of services criteria. State regulatory commissions also can
regulate the rates charged by new telecommunications service providers for
intrastate and local services and can set prices for interconnection by new
telecommunications service providers with the incumbent telephone company
networks, in accordance with guidelines set by the FCC. In addition, state
regulatory commissions in many instances have authority under state law to adopt
additional regulations governing local competition, so long as the state's
actions are not inconsistent with federal law or regulation.

    Most state regulatory commissions require companies that wish to provide
intrastate common carrier services to register or be certified to provide these
services. These certifications generally require a showing that the carrier has
adequate financial, managerial and technical resources to offer the proposed
services in a manner consistent with the public interest. In most states, we are
also required to file tariffs setting forth the terms, conditions and prices for
services that are classified as intrastate, and to update or amend our tariffs
as rates change or new products are added. We may also be subject to various
reporting and record-keeping requirements.

    We are currently certified by the Missouri Public Service Commission, the
Kansas Corporation Commission, the Texas Public Utilities Commission and the
Oklahoma Corporation Commission to provide both local and intrastate long
distance service in those states. We have tariffs on file in each of these
states.

    If we choose to install our own transmission facilities, we may be required,
in some cities, to obtain street opening and construction permits, permission to
use rights-of-way, zoning variances and other approvals from municipal
authorities. We also may be required to obtain a franchise to place facilities
in public rights of way. In some areas, we may be required to pay license or
franchise fees for these approvals. We cannot assure you that fees will remain
at current levels, or that our competitors will face the same expenses, although
the Telecommunications Act does require that any fees charged by municipalities
be reasonable and non-discriminatory as among telecommunications carriers.

BOARD COMPOSITION

    The number of directors is set at 11. In accordance with the terms of our
certificate of incorporation, as amended and restated prior to the closing of
this offering, the terms of the office of the board of directors will be divided
into three classes, with each class holding office for staggered three year
terms:

    - Class I directors' terms will expire at the annual meeting of stockholders
      to be held in 2001;

    - Class II directors' term will expire at the annual meeting of stockholders
      to be held in 2002; and

    - Class III directors' term will expire at the annual meeting of
      stockholders to be held in 2003.

    The Class I directors will be Messrs. Clammer, Ejabat and Palmer. The
Class II directors will be Messrs. Bradley, Kravis and Roberts. The Class III
directors will be Messrs. Greene, Jalkut, Navab and Scott. Currently, there is
one vacancy on the board. When this vacancy is filled, we intend for the new
director to be a Class I director. At each annual meeting of stockholders after
the initial classification of the board of directors, the successors to
directors whose term 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
possible, each class will consist of one-third of the directors. This
classification of the board of directors may have the effect of delaying or
preventing changes in our control or management. Directors may be removed for
cause by the affirmative vote of the holders of a majority of the common stock.

BOARD COMMITTEES

    AUDIT COMMITTEE.  The audit committee is responsible for, among other
things, making recommendations concerning the engagement of our independent
public accountants, reviewing with the independent public accountants the plans
and results of the audit engagement, approving professional services provided by
the independent public accountants, reviewing the independence of the
independent public accountants, considering the range of audit and non-audit
fees and reviewing the adequacy of our internal accounting controls. Upon
completion of the offering, the audit committee will consist of
Messrs. Bradley, Ejabat and Jalkut.

    COMPENSATION COMMITTEE.  The compensation committee is responsible for
determining compensation for our executive officers and administering the 1998
Employee Stock Option Plan and the 2000 Equity Participation Plan. Since
August 1999, the compensation committee consists of Messrs. Navab, Bradley and
Greene.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    None of the members of the compensation committee of the board of directors
is currently or has been, at any time since our formation, our officer or
employee.

DIRECTOR COMPENSATION

    Directors who are also our executive officers do not receive any additional
compensation for serving as members of the board of directors or any of its
committees. Non-employee directors are expected to receive a cash stipend of
$5,000 payable annually and reimbursement of expenses for serving on the board
of directors and any committees of the board, as well as an annual option to
purchase 5,000 shares of common stock under the 2000 Equity Participation Plan.
Each non-employee director currently on the board will receive an option to
purchase 10,000 shares of common stock upon completion of the offering at the
offering price. These options will vest in equal annual installments over the
next four years. In addition, Messrs. Ejabat and Jalkut each received on
March 22, 2000 an

                                       57

additional option to purchase 30,000 shares of common stock at an exercise price
of $7.50 per share. These options will vest in equal annual installments over
the next two years.

(1) Includes options to purchase shares of our common stock, which were issued
    under our 1998 employee stock option plan. Prior to the private placement of
    our series B preferred stock, we were a party to various stock option
    agreements with our employees, all of which were governed by our 1997 stock
    option plan. In connection with the 1998 private placement of series B
    preferred stock, the 1997 stock option plan was replaced with the 1998 stock
    option plan, and all stock option agreements governed by the 1997 stock
    option plan were terminated. Options issued to the members of management
    during 1998 were granted under our 1998 employee stock option plan and were
    exercisable immediately on grant at an exercise price of $0.001 per share.
    The shares issued under these options vest over a four-year period, at a
    rate of 6.25% per quarter. Options issued during 1999 were also granted
    under our 1998 stock option plan and vest 25% at the first anniversary of
    the grant, then 6.25% per quarter thereafter. All stock options have been
    adjusted to reflect a stock dividend made on June 23, 1998. Holders of
    exercised options have voting power with respect to all shares of common
    stock underlying the options. Upon termination of employment, we have the
    right to repurchase all options which have not vested as of that date,
    subject to some exceptions.

(2) Reflects matching contributions made by us under our 401(k) plan.

(3) Reflects compensation paid to Messrs. Scott and Lawhon commencing in
    January 1997.

(6) Mr. Sauder joined us after the Valu-Line acquisition and currently serves as
    vice president. Compensation listed was paid by Valu-Line from January 1997
    to February 1998.

(1) Options granted to purchase shares of our common stock were made under our
    1998 employee stock option plan. In the event that a purchaser ceases to
    provide service to us and our affiliates, we have the right to repurchase
    any of that person's unvested shares of common stock at the original option
    exercise price. These options vest 25% on the first anniversary of the grant
    date and quarterly thereafter at a rate of 6.25%.

(2) The percentage of total options was calculated based on options to purchase
    an aggregate of 1,744,800 shares of common stock granted to employees under
    the 1998 stock option plan in 1999.

(3) The potential realizable value was calculated based on the ten-year term of
    the options and assumed rates of stock appreciation of 5% and 10%,
    compounded annually from the date the options were granted to their
    expiration date based on the fair market value of the common stock on the
    date of grant.

1998 EMPLOYEE STOCK OPTION PLAN

    Under our 1998 employee stock option plan, as amended, options to purchase
shares of our common stock in the form of both incentive stock options and
nonqualified stock options were granted to our employees or employees of certain
of our subsidiaries. A total of 7,720,845 shares of our common stock were
reserved for issuance under this option plan. As of December 31, 1999, options
to acquire 1,980,850 shares were issued and outstanding with a weighted average
exercise price of $3.59 per share. These options generally vest 25% per year
over four years from the date of grant. Under a resolution of our board of
directors, no new options may be granted under this option plan.

2000 EQUITY PARTICIPATION PLAN

    We intend to adopt prior to the closing of the offering the 2000 Equity
Participation Plan, which we also refer to as the Equity Plan. The principal
purpose of the Equity Plan is to attract, retain and motivate select officers,
employees, consultants and directors through the granting of stock-based
compensation awards. The Equity Plan will provide for a variety of these awards,
including non-qualified stock options, incentive stock options (within the
meaning of Section 422 of the Internal Revenue Code), stock appreciation rights,
restricted stock, deferred stock, dividend equivalents, performance awards,
stock payments, and other stock-related benefits. A total of       shares of
common stock will be reserved for issuance under the Equity Plan. The maximum
number of shares

                                       60
<PAGE>
that may be subject to awards granted under the Equity Plan to any individual in
any calendar year cannot exceed       .

    The Equity Plan will provide that the committee has the authority to select
the employees and consultants to whom awards are to be made, to determine the
number of shares to be subject to the Equity Plan and the terms and conditions
of the awards and the Equity Plan, and to make all other determinations and to
take all other actions necessary or advisable for the administration of the
Equity Plan for employees or consultants.

    The Equity Plan also provides that at specified times our non-employee
directors will automatically be granted options to purchase shares of our common
stock. All options granted to our non-employee directors will have an exercise
price per share equal to the fair market value per share of our common stock as
of the date of grant and all of these options will become exercisable in equal
annual installments of 25% on each of the first four anniversaries of the date
of grant. Each individual who is a non-employee director at the time of the
offering will be granted an option to purchase 10,000 shares of our common stock
at the time of the offering. After the offering, each non-employee director who
becomes a member of the board will initially receive an option to purchase
10,000 shares of our common stock upon becoming a member. In addition, all
non-employee directors will be granted an option to purchase an additional 5,000
shares of our common stock at each annual meeting of our stockholders after the
offering at which he or she is reelected to our board of directors.

    Each of the committee and the board will be authorized to adopt, amend and
rescind rules relating to the administration of the Equity Plan, and to amend,
suspend and terminate the Equity Plan. We have attempted to structure the Equity
Plan in a manner such that remuneration attributable to stock options and other
awards will not be subject to the deduction limitation contained in
Section 162(m) of the Internal Revenue Code.

2000 EMPLOYEE STOCK PURCHASE PLAN

    We intend to adopt prior to the closing of the offering the 2000 Employee
Stock Purchase Plan, or the Purchase Plan. The Purchase Plan is intended to be
an "employee stock purchase plan" as described in Section 423 of the Code. The
Purchase Plan will be administered by the compensation committee of our board of
directors. A total of       shares of our common stock will be reserved and
available for purchase under the Purchase Plan, subject to antidilution and
other adjustment provisions.

    The Purchase Plan will permit eligible employee participants to purchase our
common stock through payroll deductions at a price per share which is equal to
the lesser of 85% of the fair market value of the common stock on the first or
the last day of an offering period. The Purchase Plan will provide for two
offering periods each calendar year. The first is March 1 through August 31 and
the second is September 1 through February 28 or, in a leap year, February 29,
except that the first offering period under the Purchase Plan will begin on the
closing of the offering. On the last day of each offering period, each
participant's accrued payroll deductions will be automatically applied to the
purchase of common stock.

    Employees eligible to participate in the Purchase Plan consist of all
persons employed for at least 180 days by us or by the subsidiaries described in
the Purchase Plan, except that the Purchase Plan will exclude from participation
any employee whose customary employment is for less than 32 hours per week or
for not more than 1,000 hours during a calendar year and any employee who owns
stock representing 5% or more of the total combined voting power or value of all
classes of our stock or the stock of our subsidiaries. No participant will be
permitted to purchase shares of common stock in any calendar year under the
Purchase Plan with an aggregate fair market value (generally determined as of
the beginning of the plan year) in excess of $25,000.

401(K) PLAN

    We have adopted a tax-qualified employee savings and retirement plan, or
401(k) plan, covering all of our full-time employees. Under the 401(k) plan,
employees may elect to reduce their current compensation up to the statutorily
prescribed annual limit and have the amount of the reduction contributed to the
401(k) plan. The 401(k) plan is intended to qualify under Section 401 of the
Code so that contributions by employees to the 401(k) plan and income earned on
plan contributions are not taxable to employees until withdrawn from the 401(k)
plan. The trustees under the 401(k) plan, at the direction of each participant,
invest the participant's assets in the 401(k) plan in selected investment
options.

    of shares of common stock which have already vested, "exercisable" means
    options to purchase shares of common stock which are subject to exercise and
    "unexercisable" means all other options to purchase shares of common stock.

(2) Amounts shown under the "Value Realized" and "Value of Unexercised

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

SENIOR CREDIT FACILITY

    In December 1999, we entered into a credit agreement with a syndicate of
banks, financial institutions and other entities arranged by Lehman Commercial
Paper, Inc. The agreement includes a seven year, $50.0 million term loan
facility and a seven year $25.0 million revolving credit loan facility.

    In February 2000, we amended these term loan and revolving credit loan
facilities, resulting in a stated principal amount of $125.0 million, of which
$25.0 million is provided for a reducing revolver and $100.0 million for
multi-draw term loans. The revolver is available for general corporate purposes
of our subsidiaries and the term loans are to be used to finance
telecommunications equipment, inventory, network assets and back office systems.
These senior credit facilities are secured by a perfected first priority
security interest in substantially all of our assets and capital stock and
contain a number of financial and operational covenants with which we must
comply. Among other things, the covenants require us to comply with specified
financial ratios and tests, including minimum revenues, minimum EBITDA/maximum
EBITDA losses, minimum access lines, senior secured debt to total capitalization
ratio, maximum capital expenditures, maximum leverage ratios, minimum fixed
charge coverage ratios and pro forma debt service coverage ratios. The covenants
restrict our ability to incur additional debt, make distributions on or redeem
our capital stock, create liens or negative pledges with respect to our assets,
make investments, issue, sell or allow distributions on capital stock of our
subsidiaries, prepay or defease specified indebtedness, enter into transactions
with affiliates, enter into specified hedging arrangements, merge, consolidate
or sell our assets or engage in any business other than telecommunications.

    The loans must be repaid over a seven-year period commencing in
December 2003. Interest payments are due, at our option, either quarterly in the
case of base rate (prime based) draws or at the end of the relevant interest
period in the case of eurodollar draws. Interest will accrue at a lower rate if
we meet specified financial tests. In addition, we must pay a fee based on the
average daily unused committed portion of the credit facilities. This fee is
payable quarterly in arrears and is calculated at a rate of between 0.75% and
1.25% per annum depending upon the percentage of unused credit in the
facilities.

14% SENIOR NOTES DUE 2008

    In June 1998 we issued senior notes with a principal of $115 million along
with warrants to purchase 1,409,734 shares of common stock at $0.01 per share.
These notes, which are senior obligations, bear interest at the rate of 14% per
annum, payable semi-annually in arrears on June 15 and December 15. Payments on
these notes began on December 15, 1998.

    The senior notes are not redeemable at our option prior to June 15, 2003,
except that prior to June 15, 2003 we may redeem up to 35% of the originally
issued aggregate principal amount of the notes at a rate of 114% of the
principal amount thereof on the redemption date, plus accrued and unpaid
interest and liquidated damages, if any, with the net cash proceeds of one or
more public or private sales of common stock or preferred stock, provided that
at least 65% of the senior notes remain outstanding after the redemption. At any
time on or after June 15, 2003, the senior notes are redeemable at our option,
in whole or in part, at a premium declining ratably to par on June 15, 2006.

    The senior note indenture provides that, in the event of a change of control
of us, we will be required to make an offer to purchase in cash all or any part
of the outstanding senior notes at a price of 101% of the aggregate principal
amount thereof plus accrued and unpaid interest and liquidated damages, if any.

    The senior notes indenture contains restrictive covenants that, among other
things, impose on our ability and our restricted subsidiaries' ability to incur
additional indebtedness, merge, consolidate, sell

                                       69
<PAGE>
or dispose of all or substantially all of our assets, issue some kinds of
preferred stock, pay cash dividends or make other distributions on account of
our equity interests, repurchase equity interests or subordinated indebtedness
and make other restricted payments, create liens, enter into transactions with
affiliates, engage in any business other than telecommunications, enter into
sale and leaseback transactions and sell assets.

                          DESCRIPTION OF CAPITAL STOCK

    Upon completion of the offering, our authorized capital stock will consist
of       shares of common stock, $.001 par value.

COMMON STOCK

    As of December 31, 1999 without giving effect to the exercise by KKR of its
options to invest an additional $50.0 million in our company or to the
conversion of all outstanding shares of our preferred stock into shares of
common stock, there were 4,687,767 shares of common stock outstanding held of
record by 81 stockholders. After giving effect to KKR's exercise of its options
and the conversion of our preferred stock, as of December 31, 1999, there were
45,995,363 shares of common stock held of record by 250 stockholders. 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. Subject to preferences
that may be applicable to any outstanding shares of preferred stock, the holders
of common stock are entitled to receive ratably those dividends as may be
declared by the board of directors out of funds legally available therefor. In
the event of a 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 preferences of any outstanding shares of
preferred stock. 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. All outstanding
shares of common stock are, and all shares of common stock to be outstanding
upon completion of the offering will be, fully-paid and nonassessable.

PREFERRED STOCK

    There will be no shares of preferred stock outstanding upon completion of
the offering. Our certificate of incorporation, as amended and restated prior to
the closing of the offering, will provide our board of directors with the
authority, without further action by the stockholders, to issue up to
10,000,000 shares of preferred stock, $.001 par value, in one or more series and
to fix the powers, preferences, privileges, rights and qualifications,
limitations or restrictions thereof, 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 the series, without any further vote or action by stockholders. We believe
that the board of directors' authority to set the terms of, and our ability to
issue, preferred stock will provide flexibility in connection with possible
financing transactions in the future. The issuance of preferred stock, however,
could adversely affect the voting power of holders of common stock, and the
likelihood that the holders will receive dividend payments and payments upon
liquidation and could have the effect of delaying, deferring or preventing a
change in control in us. We have no present plan to issue any shares of
preferred stock.

WARRANTS

    We have outstanding warrants to purchase up to 1,409,734 shares of common
stock at an exercise price of $0.01 per share. These warrants are currently
exercisable and expire on June 15, 2008. The warrant agreement governing these
warrants provides the holders of the warrants with customary antidilution
protections. In addition, holders of these warrants have demand and piggyback
registration rights with respect to the exercise of their warrants and the
resale of the underlying shares. Prior to exercising their warrants, the warrant
holders do not have any voting rights relating to our company.

ANTI-TAKEOVER EFFECTS OF OUR CERTIFICATE OF INCORPORATION AND BYLAWS AND
  DELAWARE GENERAL CORPORATION LAW

    OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION AND BYLAWS AND
DELAWARE GENERAL CORPORATION LAW.  Prior to the completion of the offering, we
will amend and restate our certificate of incorporation and bylaws. Certain
provisions of Delaware law and our amended and restated certificate of
incorporation and bylaws could make the following more difficult:

    - the acquisition of us by means of a tender offer;

    - acquisition of us by means of a proxy contest or otherwise; or

    - the removal of our incumbent officers and directors.

    These provisions, summarized below, are expected to discourage certain types
of coercive takeover practices and inadequate takeover bids. These provisions
are also designed to encourage persons seeking to acquire control of us to first
negotiate with our board. We believe that the benefits of increased protection
of the potential ability to negotiate with the proponent of an unfriendly or
unsolicited proposal to acquire or restructure us outweigh the disadvantages of
discouraging these proposals because negotiation of these proposals could result
in an improvement of their terms. Moreover, each of the provisions summarized
below cannot be amended or removed from our amended and restated certificate of
incorporation or our bylaws without the vote of a supermajority of our
stockholders.

    ELECTION AND REMOVAL OF DIRECTORS.  Our board of directors will be divided
into three classes. The directors in each class will serve for a three-year
term, one class being elected each year by our stockholders. This system of
electing and removing directors may tend to discourage a third party from making
a tender offer or otherwise attempting to obtain control of us because it
generally makes it more difficult for stockholders to replace a majority of the
directors.

    In addition, our bylaws will provide that, except as otherwise provided by
law or our certificate of incorporation, newly created directorships resulting
from an increase in the authorized number of directors or vacancies on the board
may be filled only by a majority of the directors then in office, though less
than a quorum is then in office. Our certificate of incorporation will also
provide that the authorized number of directors may be changed only by a
resolution of our board.

    STOCKHOLDER MEETINGS.  Under our certificate of incorporation and bylaws,
only the chairman of the board, the chief executive officer, the president or a
majority of the board of directors will be permitted to call special meetings of
stockholders.

    REQUIREMENTS FOR ADVANCE NOTIFICATION OF STOCKHOLDER NOMINATIONS AND
PROPOSALS.  Our bylaws will establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board.

    DELAWARE ANTI-TAKEOVER LAW.  We are subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, Section 203 prohibits
a publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years following the date
the person became an interested stockholder, unless the "business combination"
or the transaction in which the person became an interested stockholder is
approved in a prescribed manner. Generally, a "business combination" includes a
merger, asset or stock sale, or other transaction resulting in a financial
benefit to the interested stockholder. Generally, an "interested stockholder" is
a person who, together with affiliates and associates, owns or within three
years prior to the determination of interested stockholder status, did own, 15%
or more of a corporation's voting stock. The existence of this provision may
have an anti-takeover effect with respect to transactions not approved in
advance by the board of directors, including discouraging attempts that might
result in a premium over the market price for the shares of common stock held by
stockholders.

                                       71
<PAGE>
    ELIMINATION OF STOCKHOLDER ACTION BY WRITTEN CONSENT.  Upon the completion
of the offering, our certificate of incorporation will eliminate the right of
stockholders to act by written consent without a meeting, unless the consent is
unanimous. This provision may have the effect of discouraging, delaying or
making more difficult a change in control of our company or preventing the
removal of incumbent directors even if a majority of our stockholders were to
deem such an action to be in our best interests.

TRANSFER AGENT AND REGISTRAR

    UMB Bank, N.A. has been appointed as the transfer agent and registrar for
our common stock.

                        SHARES ELIGIBLE FOR FUTURE SALE

    If our stockholders sell substantial amounts of our common stock, including
shares issued upon the exercise of outstanding options or warrants, in the
public market following the offering, the market price of our common stock could
decline. These sales also might make it more difficult for us to sell equity or
equity-related securities in the future at a time and price that we deem
appropriate.

    Upon completion of the offering, we will have outstanding an aggregate of
      shares of our common stock, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options or warrants. Of
these shares, all of the shares sold in the offering will be freely tradeable
without restriction or further registration under the Securities Act, unless the
shares are purchased by "affiliates" as that term is defined in Rule 144 under
the Securities Act. This leaves             shares eligible for sale in the
public market as follows:

                                       to volume limitations).

                                       At various times after 180 days from
                                       the date of this prospectus as
                                       described below under "Lock-up
                                       Agreements."
</TABLE>

RULE 144

    In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of:

    - 1% of the number of shares of our common stock then outstanding, which
      will equal approximately       shares immediately after the offering; or

    - the average weekly trading volume of our common stock on the Nasdaq
      National Market during the four calendar weeks preceding the filing of a
      notice on Form 144 with respect to that sale.

    Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us.

RULE 144(K)

    Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the three months preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell those shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

REGISTRATION RIGHTS

    On or after the date that is 180 days after completion of the offering,
holders of 45,527,135 shares of our common stock will have demand registration
rights under the Securities Act at our expense of all or a portion of the shares
of common stock they own pursuant to the purchasers rights agreement. These
holders also have "piggy-back" registration rights. In addition, holders of
warrants to purchase up to 1,409,734 shares of our common stock have piggy-back
and demand registration rights with respect to the exercise of their warrants
and the resale of the underlying shares.

                                       73
<PAGE>
LOCK-UP AGREEMENTS

    All of our officers, directors and stockholders have entered into lock-up
agreements under which they agreed not to transfer or dispose of, directly or
indirectly, any shares of our common stock or any securities convertible into or
exercisable or exchangeable for shares of our common stock, for a period of
180 days after the date of this prospectus, without the prior written consent of
Lehman Brothers Inc. and Bear, Stearns & Co. Inc. on behalf of the underwriters.

    In addition to the 180-day lock-up described above, all of our stockholders
with the exception of persons who became stockholders through the exercise of
employee stock options, all of whom held in the aggregate less than 2% of our
outstanding common stock as of March 15, 2000, have entered into the purchasers
rights agreement, which limits their ability to pledge or transfer their shares
of our stock until August 5, 2002. In addition, Messrs. David E. Scott,
Jeffrey D. Shackelford, Gary L. Chesser, David W. Vranicar, Donald M. Goldman,
Bradley A. Moline and Gregory C. Lawhon, may not transfer shares issued or
issuable upon the exercise of stock options held by them for a period of five
years from the date their respective options were granted. This five-year
limitation is subject to exceptions, including the following:

    - If KKR requests registration for some or all of its shares, then those
      holders subject to the five-year limitation may register and transfer the
      same fraction of their fully vested option shares as KKR registers of its
      shares.

    - Following the offering, the holders subject to the five-year limitation
      may each transfer up to 10% of their fully vested option shares per year,
      provided that they never transfer more than a total of 25% of those
      shares.

    In addition, 20 other key employees have each entered into a management
stockholders agreement, under which they have agreed not to transfer shares
received upon exercise of their respective options for a period of five years
from the date their respective options were granted. These limitations are
subject to exceptions, including the following:

    - If KKR requests registration for some or all of its shares, then the
      subject employees may register and transfer the same fraction of their
      fully vested option shares as KKR registers of its shares.

    - Following the offering, subject employees may each transfer up to 25% of
      their fully vested option shares per year, provided that they never
      transfer more than a total of 50% of those shares.

    All of our employees who have been granted stock options under our employee
benefits plans have each agreed in their option agreements that they will not
transfer any shares of our common stock for a period of 180 days after our
completion of a public offering of our stock if we request. We intend to make
this request.

RULE 701

    In general, under Rule 701 of the Securities Act as currently in effect, any
of our employees, consultants or advisors who purchases shares of our common
stock in connection with a compensatory stock or option plan or other written
agreement is eligible to resell those shares 90 days after we became a reporting
company under the Securities Exchange Act of 1934 in reliance on Rule 144, but
without compliance with some of the restrictions, including the holding period,
contained in Rule 144. We have been a reporting company under the Securities
Exchange Act since March 1999.

    Following the offering, we intend to file a registration statement on
Form S-8 under the Securities Act covering approximately             shares of
common stock issued or issuable upon the exercise of stock options, subject to
outstanding options or reserved for issuance under our employee and director
stock benefit plans. Accordingly, shares registered under the registration
statement will, subject to Rule 144 provisions applicable to affiliates, be
available for sale in the open market, except to the extent that the shares are
subject to vesting restrictions or the contractual restrictions described above.

              CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS FOR
                           NON-UNITED STATES HOLDERS

    This is a general discussion of certain United States federal tax
consequences of the acquisition, ownership, and disposition of our common stock
by a holder that, for U.S. federal income tax purposes, is not a U.S. person as
we define that term below. A holder of our common stock who is not a U.S. person
is a non-U.S. holder. We assume in this discussion that you will hold our common
stock issued pursuant to the offering as a capital asset (generally, property
held for investment). We do not discuss all aspects of U.S. federal taxation
that may be important to you in light of your individual investment
circumstances, such as special tax rules that would apply to you, for example,
if you are a dealer in securities, financial institution, bank, insurance
company, tax-exempt organization, partnership or owner of more than 5% of our
common stock. Our discussion is based on current provisions of the Internal
Revenue Code of 1986, as amended, Treasury regulations, judicial opinions,
published positions of the U.S. Internal Revenue Service and other applicable
authorities, all as in effect on the date of this prospectus and all of which
are subject to differing interpretations or change, possibly with retroactive
effect. We have not sought, and will not seek, any ruling from the Internal
Revenue Service or opinion of counsel with respect to the tax consequences
discussed in this prospectus, and there can be no assurance that the Internal
Revenue Service will not take a position contrary to the tax consequences
discussed below or that any position taken by the Internal Revenue Service would
not be sustained. We urge you to consult your tax advisor about the U.S. federal
tax consequences of acquiring, holding, and disposing of our common stock, as
well as any tax consequences that may arise under the laws of any foreign,
state, local, or other taxing jurisdiction.

    For purposes of this discussion, a U.S. person means any one of the
following:

    - a citizen or resident of the U.S.

    - a corporation, partnership, or other entity created or organized in the
      U.S. or under the laws of the U.S. or of any political subdivision of the
      U.S.

    - an estate, the income of which is includible in gross income for U.S.
      federal income tax purposes regardless of its source.

    - a trust, the administration of which is subject to the primary supervision
      of a U.S. court and that has one or more U.S. persons who have the
      authority to control all substantial decisions of the trust.

DIVIDENDS

    Dividends paid to a non-U.S. holder will generally be subject to withholding
of U.S. federal income tax at the rate of 30%. If, however, the dividend is
effectively connected with the conduct of a trade or business of the U.S. by the
non-U.S. holder, the dividend will be subject to U.S. federal income tax imposed
on net income on the same basis that applies to U.S. persons generally, and, for
corporate holders under certain circumstances, the branch profits tax. Non-U.S.
holders should consult any applicable income tax treaties that may provide for a
reduction of, or exemption from, withholding taxes. For purposes of determining
whether tax is to be withheld at a reduced rate as specified by a treaty, we
generally will presume that dividends we pay on or before December 31, 2000, to
an address in a foreign country are paid to a resident of that country.

    Under recently finalized Treasury regulations, which in general apply to
dividends that we pay after December 31, 2000, to obtain a reduced rate of
withholding under a treaty, a non-U.S. holder generally will be required to
provide certification as to that non-U.S. holder's entitlement to treaty
benefits. These regulations also provide special rules to determine whether, for
purposes of applying a treaty, dividends that we pay a non-U.S. holder that is
an entity should be treated as paid to holders of interests in that entity.

                                       75
<PAGE>
GAIN ON DISPOSITION

    A non-U.S. holder will generally not be subject to United States federal
income tax, including by way of withholding, on gain recognized on a sale or
other disposition of our common stock unless any one of the following is true:

    - the gain is effectively connected with the conduct of a trade or business
      in the U.S. by the non-U.S. holder

    - the non-U.S. holder is a nonresident alien individual present in the U.S.
      for 183 or more days in the taxable year of the disposition and certain
      other requirements are met

    - the non-U.S. holder is subject to tax pursuant to provisions of the U.S.
      federal income tax law applicable to certain U.S. expatriates

    - we are or have been during certain periods a "United States real property
      holding corporation" for U.S. federal income tax purposes.

    We believe that we are not currently and will not become a United States
real property holding corporation.

    Gain that is effectively connected with the conduct of a trade or business
in the U.S. by the non-U.S. holder will be subject to the U.S. federal income
tax imposed on net income on the same basis that applies to U.S. persons
generally, and, for corporate holders under certain circumstances, the branch
profits tax, but will generally not be subject to withholding. Non-U.S. holders
should consult any applicable income tax treaties that may provide for different
rules.

UNITED STATES FEDERAL ESTATE TAXES

    Our common stock that is owned or treated as owned by an individual who is
not a citizen or resident of the U.S., as specially defined for U.S. federal
estate tax purposes, on the date of that person's death will be included in his
or her estate for U.S. federal estate tax purposes, unless an applicable estate
tax treaty provides otherwise.

INFORMATION REPORTING AND BACKUP WITHHOLDING

    Generally, we must report annually to the Internal Revenue Service and to
each non-U.S. holder the amount of dividends that we paid to a holder, and the
amount of tax that we withheld on those dividends. This information may also be
made available to the tax authorities of a county in which the non-U.S. holder
resides.

    Under current U.S. Treasury regulations, U.S. information reporting
requirements and backup withholding tax will generally not apply to dividends
that we pay on our common stock to a non-U.S. holder at an address outside the
U.S. Payments of the proceeds of a sale or other taxable disposition of our
common stock by a U.S. office of a broker are subject to both backup withholding
at a rate of 31% and information reporting, unless the holder certifies as to
its non-U.S. holder status under penalties of perjury or otherwise establishes
an exemption. Information reporting requirements, but not backup withholding
tax, will also apply to payments of the proceeds of a sale or other taxable
disposition of our common stock by foreign offices of U.S. brokers or foreign
brokers with certain types of relationships to the U.S. unless the broker has
documentary evidence in its records that the holder is a non-U.S. holder and
certain other conditions are met or the holder otherwise established an
exemption.

    Backup withholding is not an additional tax. Any amounts that we withhold
under the backup withholding rules will be refunded or credited against the
non-U.S. holder's U.S. federal income tax liability if certain required
information is furnished to the Internal Revenue Service.

    The U.S. Treasury Department has promulgated final regulations regarding the
withholding and information reporting rules discussed above. In general, those
regulations do not significantly alter the substantive withholding and
information reporting requirements but unify current certification procedures
and forms and clarify reliance standards. The final regulations are generally
effective for payments made after December 31, 2000, subject to transition
rules.

</TABLE>

    The underwriting agreement provides that the underwriters' obligations to
purchase shares of common stock depend on the satisfaction of the conditions
contained in the underwriting agreement, and that if any of the shares of common
stock are purchased by the underwriters under the underwriting agreement, then
all of the shares of common stock the underwriters have agreed to purchase under
the underwriting agreement must be purchased. The conditions contained in the
underwriting agreement include that:

    - the representations and warranties made by us to the underwriters are
      true;

    - there is no material change in the financial markets; and

    - we deliver customary closing documents to the underwriters.

    The representatives have advised us that 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 selected dealers, who may
include the underwriters, at such public offering price less a selling
concession not in excess of $  per share. The underwriters may allow, and the
selected dealers may reallow, a concession not in excess of $  per share to
brokers and dealers. After the offering, the underwriters may change the
offering price and other selling terms.

    We estimate that our share of the total expenses of the offering, excluding
the underwriting discount will be approximately $          .

    We have granted to the underwriters an option to purchase up to an aggregate
of             additional shares of common stock, exercisable to cover any
over-allotments, if any, at the public offering price less the underwriting
discount shown on the cover page of this prospectus. The underwriters may
exercise this option at any time, and from time to time, until 30 days after the
date of the underwriting agreement. To the extent that the underwriters exercise
this option, each underwriter will be committed, so long as the conditions of
the underwriting agreement are satisfied, to purchase a number of additional
shares of common stock proportionate to that underwriter's initial commitment as
indicated in the preceding table, and we will be obligated, under such
over-allotment option, to sell the shares of common stock to the underwriters.

                                       77

    We and our directors, officers, and all current stockholders have agreed not
to offer to sell, sell or otherwise dispose of, directly or indirectly, any
shares of capital stock or any securities that may be converted into or
exchanged for any shares of capital stock for a period of 180 days period from
the date of the prospectus without the prior written consent of Lehman
Brothers Inc. and Bear, Stearns & Co. Inc., except that we may issue, and grant
options to purchase, shares of common stock under our option plans.

    Before this offering, there has been no public market for the shares of
common stock. The initial public offering price will be negotiated between the
representatives and us. In determining the initial public offering price of the
common stock, the representatives will consider, among other things and in
addition to prevailing market conditions:

    - our historical performance and capital structure;

    - estimates of our business potential and earning prospects;

    - an overall assessment of our management; and

    - the consideration of the above factors in relation to market valuations of
      companies in related businesses.

    Thomas Weisel Partners LLC, one of the representatives, was organized and
registered as a broker/dealer in December 1998. Since December 1998, Thomas
Weisel Partners has acted as a lead or co-manager on numerous public offerings
of equity securities. Thomas Weisel Partners does not have any material
relationship with us or any of our officers, directors or other controlling
persons, except with respect to its contractual relationship with us under the
underwriting agreement entered into in connection with this offering.

    Fidelity Capital Markets, a division of National Financial Services
Corporation, is acting as an underwriter in this offering, and will be
facilitating electronic distribution of information through the Internet,
intranet and other proprietary technology.

    We have applied to list our common stock on the Nasdaq National Market under
the trading symbol "BRCH."

    We have agreed to indemnify the underwriters against liabilities related to
the offering, including liabilities under the Securities Act and liabilities
incurred in connection with the directed share program referred to below, and to
contribute to payments that the underwriters may be required to make for these
liabilities.

    Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
selling group members to bid for and purchase shares of common stock. As an
exception to these rules, the representatives are permitted to engage in
transactions that stabilize the price of common stock. These transactions may
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the common stock.

    The underwriters may create a short position in the common stock in
connection with the offering. This means that they may sell more shares of
common stock than are shown on the cover page of this prospectus. If the
underwriters create a short position, then the representatives may reduce that
short position by purchasing common stock in the open market. The
representatives also may elect to reduce any short position by exercising all or
part of the over-allotment option. The underwriters have informed us that the
they do not intend to confirm sales to discretionary accounts that exceed 5% of
the total number of shares of common stock offered by them.

    The representatives also may impose a penalty bid on underwriters and
selling group members. This means that, if the representatives purchase shares
of common stock in the open market to reduce the underwriters' short position or
to stabilize the price of the common stock, they may reclaim the

                                       78

amount of the selling concession from the underwriters and selling group members
who sold those shares as part of the offering.

    In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid could have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
an offering.

    Neither we nor any of the underwriters make any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the common stock. In addition, neither we nor any
of the underwriters makes any representation that the representatives will
engage in these stabilizing transactions or that any transaction, once
commenced, will not be discontinued without notice.

    At our request,                    has reserved up to       shares of the
common stock,   % of the common stock offered by this prospectus, for sale
pursuant to a directed share program to our employees, directors and friends at
the initial public offering price set forth on the cover page of this
prospectus. These persons must commit to purchase no later than the close of
business on the day following the date of this prospectus. The number of shares
available for sale to the general public will be reduced to the extent these
persons purchase the reserved shares.

    Certain of the representatives have from time to time provided investment
banking, financial advisory and other services to us for which these
representatives received customary fees and commissions. Lehman Brothers Inc.
acted as lead arranger of our senior credit facility and its affiliate, Lehman
Commercial Paper Inc., is the administrative agent of the senior credit
facility. In addition, First Union Securities, Inc. is a lender under our senior
credit facility. Lehman Brothers Inc. was an initial purchaser of our senior
notes. In addition, Lehman Brothers Inc. acted as placement agent in connection
with the private placement of shares of our series F preferred stock in
August 1999. Lehman Brothers Inc. has also served as the solicitation agent in
connection with the related solicitation of consents from holders of our senior
notes.

                         REPORT OF INDEPENDENT AUDITORS

THE BOARD OF DIRECTORS AND STOCKHOLDERS
BIRCH TELECOM, INC.

    We have audited the accompanying consolidated balance sheets of Birch
Telecom, Inc. (Birch) as of December 31, 1998 and 1999, and the related
consolidated statements of operations, stockholders' equity (deficit) and cash
flows for each of the three years in the period ended December 31, 1999. These
financial statements are the responsibility of Birch's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Birch
Telecom, Inc. at December 31, 1998 and 1999, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1999, in conformity with accounting principles generally accepted
in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. THE COMPANY

    Birch Telecom, Inc. was incorporated on December 23, 1996, as a Delaware
corporation for the purpose of providing local, long distance, Internet access,
and other communications services to business and residential customers. The
consolidated financial statements of Birch Telecom, Inc. include the accounts of
Birch Telecom, Inc. and the accounts of its wholly-owned subsidiaries
(collectively, Birch). Birch currently serves certain markets in Missouri,
Kansas and Texas. Birch's business is highly competitive and is subject to
various federal, state and local regulations.

    Birch was in the development stage for the period from December 23, 1996
(date of inception) to February 10, 1998. Accordingly, Birch had no operating
revenue and incurred operating losses and operating cash flow deficits during
that period.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    CASH AND CASH EQUIVALENTS

    For purposes of reporting cash flows, Birch includes as cash and cash
equivalents highly liquid investments with original maturities of three months
or less.

    REVENUE RECOGNITION

    Revenue for communications services is recognized when customers use the
associated services. Equipment revenue is recognized when systems or services
are substantially complete. Revenue on billings to customers in advance of
providing services is deferred and recognized when earned. Customers are not
charged fees to activate initial service.

    COST OF SERVICES

    Cost of services includes local and long-distance services purchased from
incumbent local exchange carriers, interexchange carriers and certain providers
of fiber optic telephone networks. Cost of services also includes costs
associated with the sale and installation of telephone systems.

    INVENTORY

    Inventory is carried at the lower of average cost or market determined on a
first-in, first-out basis and consists primarily of parts and equipment used in
the maintenance and installation of telephone systems.

    ADVERTISING COSTS

    Advertising costs are expensed as incurred and totaled $895,000 in 1998 and
$3.0 million in 1999. There were no advertising costs in 1997.

    PROPERTY AND EQUIPMENT

    Property and equipment is stated at cost and depreciated using the
straight-line method over the following estimated useful lives of the assets:

Buildings, furniture, fixtures and equipment................    2-40
</TABLE>

    GOODWILL AND OTHER INTANGIBLES

    Goodwill represents the excess of the purchase price paid over the fair
value of the net assets acquired in Birch's acquisitions. Goodwill is being
amortized over 25 years using the straight-line method. Accumulated amortization
on goodwill totaled $599,000 at December 31, 1998 and $1.4 million at
December 31, 1999.

    Other intangibles consist primarily of customer lists related to Birch's
acquisitions, deferred financing costs and deferred line installation costs.
Customer lists are amortized over 5 years using the straight-line method. The
deferred financing costs are amortized over 5 to 10 years, the term of the
associated financing, using the straight-line method. Deferred line installation
costs are being amortized over 2 years, the approximate average life of customer
contracts, using the straight-line method (see Note 6).

    Birch reviews its long-lived assets in accordance with Statement of
Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-lived Assets and Long-lived Assets to be Disposed of," for impairment
whenever events or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable. If such events or changes in circumstances are
present, a loss is recognized if the carrying value of the asset is in excess of
the sum of the undiscounted cash flows expected to result from the use of the
asset and its eventual disposition. An impairment loss is measured as the amount
by which the carrying amount of the asset exceeds the fair value of the asset.

    INCOME TAXES

    Birch accounts for income taxes in accordance with SFAS No. 109, Accounting
for Income Taxes. Birch recognizes deferred tax assets and liabilities for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax assets and
liabilities are determined based on the differences between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse. Net
deferred tax assets are reduced by a valuation allowance when appropriate (see
Note 14). Deferred tax assets and liabilities are adjusted for the effects of
changes in tax laws and rates on the date of enactment.

    STOCK OPTIONS

    Birch has adopted the disclosure provisions of SFAS No. 123, Accounting for
Stock-Based Compensation, which establishes a fair value based method for the
financial reporting of its stock-based employee compensation plans. However, as
allowed by SFAS No. 123, Birch has elected to continue to measure compensation
using the intrinsic value based method as prescribed by Accounting Principles

                              BIRCH TELECOM, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Board Opinion No. 25, Accounting for Stock Issued to Employees. Under this
method, compensation is measured as the difference between the market value of
the stock on the grant date, less the amount required to be paid for the stock.
The difference, if any, is charged to expense over the vesting period of the
options. The estimated market value used for the stock options granted was
determined on a periodic basis by Birch's board of directors. In accordance with
APB No. 25, Birch has recorded no compensation expense related to options
granted because the exercise price is equal to the estimated market value of the
stock on the date of grant (see Note 15).

    FAIR VALUES OF FINANCIAL INSTRUMENTS

    The carrying amount of cash and cash equivalents approximates fair value due
to the short maturity of the instruments. The fair value of Birch's pledged
securities was $38 million at December 31, 1998 and $23.3 million at
December 31, 1999. The fair value of Birch's senior notes is estimated to be
$106 million at December 31, 1998 and $115 million at December 31, 1999 based on
the quoted market rates for the debt. The fair value of other long-term debt,
accounts receivable, accounts payable and accrued expenses approximates the
recorded value.

    USE OF ESTIMATES IN FINANCIAL STATEMENTS

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

    LOSS PER SHARE

    The net loss per share amount reflected on the consolidated statement of
operations is based on the weighted-average number of common shares outstanding.
Stock options and convertible preferred stock are anti-dilutive, and therefore
excluded from the computation of earnings per share. In the future, these stock
equivalents may become dilutive.

    RECLASSIFICATIONS

    Certain items in the 1997 and 1998 consolidated financial statements have
been reclassified to be consistent with the classification in the 1999
consolidated financial statements.

    NEW ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities, which
supersedes SFAS No. 80, Accounting for Futures Contracts, SFAS No. 105,
Disclosure of Information About Financial Instruments with Off-Balance-Sheet
Risk and Financial Instruments with Concentration of Credit Risk, and SFAS
No. 119, Disclosures about Derivative Financial Instruments and Fair Value of
Financial Instruments, and also amends certain aspects of other SFAS's
previously issued. SFAS No. 133 establishes accounting and reporting standards
for derivative instruments and hedging activities. It requires that an entity
recognize all derivatives as either assets or liabilities in the balance sheet
and measure those instruments at fair value. SFAS No. 133 is effective for our
consolidated financial statements for the

year ending December 31, 2001. We do not expect the impact of SFAS No. 133 to be
material in relation to its consolidated financial statements.

3. ACQUISITIONS

    In February 1998, Birch merged with Valu-Line Companies, Inc. (Valu-Line) in
a transaction valued at $19.5 million, consisting of $4.75 million in cash,
2,968,750 shares of series A preferred stock having an aggregate liquidation
preference of $4.75 million and 6,250,000 shares of series C preferred stock
having an aggregate liquidation preference of $10.0 million. Since 1982,
Valu-Line has been primarily providing switched long distance services, customer
premises equipment (CPE) sales and services and, since March 1997, local
service.

    In May 1998, Birch acquired Boulevard Phone Company (Boulevard), a shared
tenant service provider in the Kansas City metropolitan area, for $300,000 in
cash and Telesource Communications, Inc. (Telesource), a CPE provider in the
Kansas City metropolitan area, for $325,000 in cash.

    In September 1998, Birch acquired TFSnet, Inc. (TFSnet), an Internet service
provider based in the Kansas City metropolitan area, for $2.65 million.

    In February 1999, Birch acquired American Local Telecommunications, LLC
(ALT), a competitive local exchange carrier based in the Dallas, Texas
metropolitan area. The acquisition included substantially all assets of ALT. The
total purchase price was approximately $1.6 million in cash and $211,000 in
common stock.

    In March 1999, Birch acquired the stock of Capital Communications
Corporation (Capital), a telecommunications equipment provider based in the St.
Louis, Missouri metropolitan area. The total purchase price was approximately
$3.0 million plus additional cash consideration, recorded as additional purchase
price, based on local service lines converted to Birch's service from Capital's
existing customer base, which totaled approximately $161,000 through
December 31, 1999.

    All of the acquisitions referenced above were recorded using the purchase
method of accounting. Accordingly, the operations of each are included in the
consolidated statements of operations and cash flows from the date of
acquisition.

    The following is unaudited pro forma information reflecting the effect of
the 1998 acquisitions on the results as though they had been completed effective
January 1, 1997 and 1998:

    During December 1999, Birch completed a $75 million senior credit facility
which increased to $125 million during syndication in February 2000. The
financing provides for a $25 million reducing revolver and $100 million in

purposes of Birch's subsidiaries and the term loans are to be used to finance
the development, design, installation and acquisition of telecommunications
equipment, inventory network assets and back office systems. At Birch's
election, the borrowings bear interest at either the Prime Rate plus a margin
ranging from 1.50% to 2.50% or the London Interbank Offered Rate (LIBOR) plus a
margin ranging from 2.75% to 3.75%. The applicable margins are based upon
Birch's debt to EBITDA ratio, as defined by the senior credit facility. Interest
is paid quarterly in arrears for loans bearing interest based upon Prime and/or
on the last day of each relevant interest period, for periods not in excess of
three months, for LIBOR loans. For LIBOR loans with interest periods of longer
than three months, interest is paid each day which is three months after the
first day of such interest period and the last day of such interest period.
Commitment fees are paid quarterly in arrears on the average unused committed
portion of the Facility, ranging from 0.75% to 1.25%. The applicable percentages
are based upon Birch's average borrowings in relation to the average borrowing
availability, as defined by the senior credit facility. For the year ended
December 31, 1999 commitment fees totaled $25,174. Principal payments begin
March 2003 and the credit facility matures December 30, 2006. The senior credit
facility is secured by a perfected first priority security interest in
substantially all of Birch's assets and capital stock. Deferred financing costs
incurred amounting to $1.5 million at December 31, 1999 are being amortized over
the life of the credit facility using the straight-line method. Amortization for
the year ended December 31, 1999 was not significant.

    During June 1998, Birch completed a $115 million private offering of 14%
senior notes due June 2008 and 115,000 warrants to purchase 1,409,734 shares of
common stock. Interest on the senior notes is payable semi-annually in arrears
on June 15 and December 15 of each year. Warrants are exercisable at $0.01 per
share and expire June 2008. Birch received net proceeds from the senior notes of
$110.2 million and concurrently purchased pledged securities of $44.2 million.
The pledged securities are restricted for interest payments on the senior notes
and, together with the interest accruing thereon, will be used to satisfy such
interest payments through June 2001. Birch classifies its pledged securities,
consisting of $37.8 million at December 31, 1998 and $23.4 million at
December 31, 1999 of U.S. Treasury securities, as held to maturity recorded at
amortized cost and maturing between six and eighteen months. A portion of the
proceeds from the senior notes, $337,000, was allocated to the warrants, and the
resulting debt discount is being amortized over the life of the debt on the
straight-line method, which does not differ materially from the effective
interest method. Unamortized discount was $319,000 at December 31, 1998 and
$285,000 at December 31, 1999. The amount allocated to the warrants represents
the estimated fair value of the warrants at the date of issuance. Deferred
financing costs incurred amounting to $4.9 million at December 31, 1999 are
being amortized over the life of the senior notes using the straight-line
method. Accumulated amortization on the financing costs totaled $1.5 million at
December 31, 1999. The senior notes rank pari pasu in right of payment to all
existing and future senior indebtedness of Birch and rank senior in the right of
payment to all existing and future subordinated indebtedness of Birch.

    A Registration Statement on Form S-4, registering Birch's 14% senior notes
and exchanging the outstanding senior notes for exchange notes, was declared
effective by the Securities and Exchange Commission (SEC) in March 1999. The
terms and conditions of the exchange notes are identical to those of the senior
notes in all material respects.

    The senior credit facility and the senior notes indenture contain certain
covenants which, among other things, restrict the ability of Birch to incur
additional indebtedness, pay dividends or make

    Amortization expense for assets under capital leases was $157,000 for 1998
and $974,165 for 1999.

9. CAPITAL STRUCTURE

    During 1997, $1.8 million of common stock and $18,000 of warrants were sold
to management and equity investors for $1.00 and $0.01 per share, respectively.
The warrants entitled the holders to purchase an additional 1.8 million shares
of common stock at $1.00 per share.

    During February and March 1998, Birch issued $9.5 million of series B
preferred stock at $4.50 per share and $3.5 million of convertible notes
generating net proceeds of $12.4 million, converted all existing common stock to
series C preferred stock, terminated common stock warrants, canceled the 1997
stock option plan, created the 1998 stock option plan and issued 474,750 shares
of common stock to employees of Birch. Also during February 1998, Birch issued
$4.75 million of series A preferred stock and $10.0 million of series C
preferred stock in connection with the Valu-Line merger. Birch redeemed the
series A preferred stock in June 1998. Also in June 1998, the convertible notes
were converted into series B preferred stock.

    During July and August 1999, Birch issued $10 million of series D preferred
stock and $60 million of series F preferred stock at $4.50 per share. Options
were granted to purchase $25 million of series F preferred stock at $4.75 per
share and $25 million of series F preferred stock at $5.00 per share which
expire on April 13, 2000. Additionally, Birch repurchased $10 million of
series C preferred stock at $4.50 and recapitalized the series B preferred stock
converting it into a new series B preferred stock and a new series E preferred
stock. The series E preferred stock was then redeemed for $8.6 million. Net
proceeds generated from these transactions totaled $44.4 million.

    AUTHORIZED SHARES

    At December 31, 1999, Birch had shares authorized totaling 80 million shares
of common stock and 55 million shares of preferred stock. The preferred stock
has designations of 8.75 million shares of series B, 8.5 million shares of
series C, 2.2 million shares of series D, 1.9 million shares of series E and
30 million shares of series F.

9. CAPITAL STRUCTURE (CONTINUED)
    RIGHTS

    All classes of preferred stock are convertible and contain certain voting
rights. The common stock also has voting rights similar to the series C
preferred stock. The series B, series D and series F preferred stock have
additional voting rights in certain circumstances. Additionally, the series F
preferred stock contains mandatory redemption rights based on certain senior
management retention. In the event of mandatory redemption, the shares are
redeemable for amounts similar to the liquidation preference discussed below.

    LIQUIDATION RIGHTS

    Birch's series D and series F preferred stock have a liquidation preference
over the series B and series C preferred stock and common stock at the greater
of (i) the purchase price plus accrued but unpaid dividends or (ii) the amount
the holders would have received upon liquidation if such shares of series D and
series F preferred stock had been converted to common stock immediately prior to
liquidation. Birch's series B preferred stock has a liquidation preference only
over series C preferred stock and common stock at an amount equal to the sum of
the purchase price plus accrued but unpaid dividends. series C preferred stock
has preference only over common stock at an amount equal to the sum of the
purchase price plus accrued but unpaid dividends.

    DIVIDENDS

    The series B preferred stock accrued cumulative compounding dividends at 15%
per annum until the series B was converted and restated into new series B. At
that time, the rights and preferences were amended and restated to remove the
mandatory dividend rights and now the series B cumulates cash dividends at 15%
per annum, amounting to $814,000 at December 31, 1999. The series C preferred
stock has a 10% non-cumulative cash dividend and the series D preferred stock
cumulates cash dividends at a rate of 15% per annum, totaling $750,000 at
December 31, 1999. Only the series F preferred stock contains mandatory dividend
rights. Accrued cash dividends on series F preferred stock totaled $3.6 million
at December 31, 1999, as reflected in stockholders' equity. Common stock
dividends, if any, will be declared at the discretion of Birch's board of
directors. Birch has not paid any cash dividends on common stock since inception
and does not intend to pay any in the foreseeable future. Restrictions contained
in the senior credit facility agreement and the senior notes indenture prohibit
Birch from paying certain dividends on its capital stock.

    On June 23, 1998, Birch paid a stock dividend, in the amount of 0.055 shares
per share, to the holders of Birch's series B preferred stock, series C
preferred stock and common stock as of June 15, 1998. Dividends paid on
series A preferred stock in 1998 totaled $168,000.

10. RELATED-PARTY TRANSACTIONS

    During December 1997, Birch borrowed $250,000 from Birch's principal
stockholder under a note payable. The note payable was fully repaid in
February 1998.

    Birch acquired notes payable to Valu-Line shareholders totaling $274,000 in
the Valu-Line merger. These notes were fully repaid during 1998.

    A broadcasting company owned by one of the Birch's shareholders rented
office space from Birch for $30,000 during 1998 and $29,187 during 1999. Birch
purchased advertising from the broadcasting company totaling $40,000 in 1998 and
$30,360 in 1999.

    A real estate company owned by the President of Birch's equipment division
was paid $3,588 for building maintenance in 1998 and $12,587 in 1999.

</TABLE>

    Total rent expense was $81,000 in 1997, $485,000 in 1998 and $1.5 million in
1999. Birch may renew leases on its corporate offices in terms ranging from
three to ten years at rates approximating the prevailing market. Renewal rentals
are excluded from the table.

    Various suits arising in the ordinary course of business are pending against
Birch. Management cannot predict the final outcome of the actions, but believes
they will not be material to Birch's financial statements.

12. EMPLOYEE BENEFIT PLAN

    Birch sponsors a 401(k) profit-sharing plan covering substantially all
employees under which employees can contribute up to 15% of their annual salary
subject to annual maximum limitations. Employees can participate after meeting
the plan's eligibility requirements. Birch may also make discretionary
contributions. Birch contributions to the plan were $148,000 in 1998 and
$594,925 in 1999.

13. EMPLOYMENT AGREEMENTS

    Birch has entered into employment agreements with certain executive
employees which provide for payments to be made in connection with certain
termination of employment or change of control. The benefits include cash
compensation, immediate vesting of outstanding stock options and coverage under
Birch's group health plan.

</TABLE>

    Net income tax benefits of approximately $5.1 million in 1998 and $22.9 in
1999 have been offset by increases in the valuation allowance. At December 31,
1999, Birch had operating loss carryforwards for federal income tax purposes of
approximately $71.9 million, expiring in 2013 and 2014.

    The primary difference that caused the effective tax rate to vary from the
statutory federal income tax rate of 35% was the valuation allowance.

15. STOCK OPTION PLAN

    At December 31, 1997, Birch had granted options to purchase common stock
under the 1997 stock option plan. The options granted had a term of 10 years and
vested over a four-year period. This plan was terminated and superseded in 1998
by the 1998 employee stock option plan. No options were or ever will be
exercised and no shares were or will ever be issued under the terminated and
superseded 1997 stock option plan.

    At December 31, 1999, 107,468 options were exercisable with a weighted
average exercise price of $2.175. At December 31, 1998, 5,363 options were
exercisable with a weighted average exercise price of $0.001.

    The 1998 employee stock option plan authorized the grant of options for up
to 6,195,845 shares of Birch's common stock. The options have a term of
10 years and vest over a four-year period. All options exercised during 1998
were for options granted with an early exercise provision. The shares from
exercised options continue to be subject to the four-year vesting period. No
options expired during 1998 or 1999.

    Options granted in 1998 and 1999 had exercise prices approximating the
market value of the common stock. Exercise prices for options outstanding at
December 31, 1999 ranged from $0.001 to $4.50. The weighted-average remaining
contractual life of those options is 9.4 years. The weighted-average fair values
of options granted during the years ended December 31, 1998 and 1999 equaled
$0.05 and $0.73, respectively. At December 31, 1999, Birch has reserved
1,628,956 shares of common stock for issuance under the 1998 stock option plan.

    Birch estimated the fair value of each option grant using the minimum value
method permitted by SFAS No. 123 for entities not publicly traded. Birch used
the following assumptions in the calculation: risk-free interest rate of 5.25%,
expected life of four years and no dividends being paid over the life of the
options. Under the minimum value method, the volatility factor is excluded. Had
compensation cost for the stock based compensation plan been determined as
prescribed by SFAS No. 123, the net loss and loss per common share would have
been as follows for the years ended December 31, 1997, 1998 and 1999:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

16. SIGNIFICANT SUPPLIERS

    Birch purchased telephone services from Southwestern Bell Telephone
amounting to 35% of cost of services in 1998 and 65% in 1999. Birch is dependent
upon incumbent telephone companies, such as Southwestern Bell, for the supply of
fiber optic networks that we use. Birch purchased switches and other network
equipment and software from Lucent Technologies amounting to $12.9 million in
1998 and $9.9 million in 1999.

17. YEAR 2000 ISSUE--UNAUDITED

    The Year 2000 issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of Birch's
computer programs that have date-sensitive software may recognize the date using
"00" as the year 1900 rather than the year 2000. Birch completed all Year 2000
readiness work and experienced no significant problems as a result of the new
year. Birch does not believe it has continued exposure to the Year 2000 problem
and does not expect further costs incurred in relation to the Year 2000 issue to
be substantial.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors
Valu-Line Companies, Inc.

    We have audited the accompanying consolidated balance sheet of the Valu-Line
Companies, Inc. (the Company) as of December 31, 1997, and the related
consolidated statements of income and retained earnings, and cash flows for the
year then ended. 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 audit.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Valu-Line
Companies, Inc. at December 31, 1997 and the consolidated results of its
operations and its cash flows for the year then ended in conformity with
accounting principles generally accepted in the United States.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    USE OF ESTIMATES IN FINANCIAL STATEMENTS

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

3. PROPERTY AND EQUIPMENT

    The components of property and equipment at December 31, 1997 are as
follows:

</TABLE>

    Total rent expense for 1997 was $56,000.

10. SUBSEQUENT EVENT

    In February 1998, the Company was acquired by Birch Telecom, Inc. for
$19,500,000. Shareholders of the Company received $4,750,000 of cash and
$14,750,000 of preferred stock in Birch Telecom, Inc.

11. YEAR 2000 COMPLIANCE--UNAUDITED

    Year 2000 issues arise from computer programs written using two digits
rather than four to define the applicable year. Any of the Company's computer
programs that have time-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
miscalculation causing disruptions of operations, including, among other things,
a temporary inability to process transactions, send invoices or engage in
similar normal business activities.

    Based on ongoing assessments, the Company determined that it will be
required to modify or replace portions of its software so that its computer
systems will function properly with respect to dates in the year 2000 and
thereafter. The Company presently believes that with modifications to existing
software and conversions to new software, the year 2000 issue will not pose
significant operational problems for its computer systems. The Company estimates
it will incur minimal expenses to modify and convert its systems and anticipates
completing the year 2000 project by the year ending December 31, 1998.

11. YEAR 2000 COMPLIANCE--UNAUDITED (CONTINUED)
    While the Company believes that its systems will be year 2000 compliant,
there can be no assurance until the year 2000 occurs that all systems will
function adequately. In addition, the Company interconnects and uses various
local exchange companies' facilities to service its customers, and such
facilities currently utilize numerous, date-sensitive computer applications. If
these facilities are not year 2000 compliant, or if the systems of other local
exchange companies, long distance carriers and others upon which the Company
relies are not year 2000 compliant, it could have a material effect on the
Company's business, operating results and financial condition.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    We are a Delaware corporation. Reference is made to Section 102(b)(7) of the
Delaware General Corporation Law (the "DGCL"), which enables a corporation in
its original certificate of incorporation or an amendment thereto to eliminate
or limit the personal liability of a director for violations of the director's
fiduciary duty, except (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) pursuant to Section 174 of the DGCL (providing for liability of directors
for unlawful payments of dividends of unlawful stock purchase or redemptions),
or (iv) for any transaction from which a director derived an improper personal
benefit.

    Reference is also made to Section 145 of the DGCL, which provides that a
corporation may indemnify any person, including an officer or director, who is,
or is threatened to be made, party to any threatened, pending or completed legal
action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of such corporation), by
reason of the fact that such person was an officer, director, employee or agent
of such corporation or is or was serving at the request of such corporation as a
director, officer, employee or agent of another corporation or enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided such officer,
director, employee or agent acted in good faith and in a manner he reasonably
believed to be in, or not opposed to, the corporation's best interest and, for
criminal proceedings, had no reasonable cause to believe that his conduct was
unlawful. A Delaware corporation may indemnify any officer or director in an
action by or in the right of the corporation under the same conditions, except
that no indemnification is permitted without judicial approval if the officer or
director is adjudged to be liable to the corporation. Where an officer or
director is successful on the merits or otherwise in the defense of any action
referred to above, the corporation must indemnify him against the expenses that
such officer or director actually and reasonably incurred.

                                      II-1
<PAGE>
    Article V of our amended and restated by-laws (filed as Exhibit 3.2)
provides for indemnification of the officers and directors to the full extent
permitted by applicable law.

    The underwriting agreement (Exhibit 1.1) provides for indemnification by the
underwriters of the registrant and its officers and directors for certain
liabilities arising under the Securities Act, or otherwise.

    On February 10, 1998, as part of the consideration for our acquisition of
Value-Line, we paid to the principal stockholder of Valu-Line, 2,968,750 shares
of our series A preferred stock and 5,982,746 shares of our series C preferred
stock. These issuances were exempt from registration pursuant to Section 4(2) of
the Securities Act. In June 1998, we repurchased all of the outstanding shares
of our Series A preferred held by Valu-Line's former principal stockholder.

    On March 13, 1998, we completed a private placement to approximately 70
accredited investors of 5,937,500 shares of our series B preferred stock
comprised of shares with an aggregate liquidation preference of $9.5 million and
convertible notes in the aggregate principal amount of $3.5 million. On
June 18, 1998, we converted those notes to 2,307,965 shares of series B
preferred stock. These issuances were exempt from registration pursuant to
Section 4(2) of the Securities Act.

    In connection with this series B preferred stock offering, one stockholder
surrendered 1,500,000 shares of common stock and 1,500,000 warrants exercisable
into shares of common stock in exchange for 1,582,500 shares of series C
preferred stock. One of our officers surrendered 180,000 shares of common stock
and 180,000 warrants exercisable into shares of common stock in exchange for
189,900 shares of series C preferred stock. Another of our officers surrendered
120,000 shares of common stock and 120,000 warrants exercisable into shares of
common stock in exchange for 126,600 shares of series C preferred stock. We then
cancelled the exchanged shares and warrants exercisable into shares of common
stock. These issuances were exempt from registration pursuant to Section 4(2) of
the Securities Act.

    On July 23, 1999, we completed a private placement to approximately 55 of
our existing investors in Series B of 2,222,222 shares of series D preferred
stock at a purchase price of $4.50 per share for aggregate net proceeds of
approximately $10 million. This issuance was exempt from registration pursuant
to Section 4(2) of the Securities Act.

    On August 5, 1999, BTI Ventures, L.L.C. an affiliate of KKR, purchased
13,333,334 shares of our series F preferred stock at a purchase price of $4.50
per share for aggregate net proceeds of $60.0 million. On March 23, 2000, KKR
exercised its options to purchase an additional 5,263,158 shares of series F
preferred stock at $4.75 per share and 5,000,000 shares of series F preferred
stock at $5.00 per share. In connection with the private placement of the
series F preferred stock to BTI Ventures, L.L.C., which closed on August 5,
1999, and the related exercise of the KKR options, Lehman Brothers Inc. earned
compensation which included 646,300 shares of our series D preferred stock.
These issuances were exempt from registration pursuant to Section 4(2) of the
Securities Act.

    On August 5, 1999, in connection with the series F Stock offering, we
repurchased 2,222,222 shares of our Series C preferred stock for $10 million
from a board member. This issuance was exempt from registration pursuant to
Section 4(2) of the Securities Act.

    On August 5, 1999, in connection with the series F stock offering, we
converted each outstanding share of series B preferred stock into one share of
amended and restated series B preferred stock. The holders of series B preferred
stock, approximately 70 accredited investors, surrendered their existing

                                      II-2

redemption and participating liquidation preference in exchange for 0.2222
shares of our series E preferred stock. These issuances were exempt from
registration pursuant to Section 4(2) of the Securities Act. We redeemed the
series E preferred stock for a total of $8.6 million.

    From 2/10/98 to 3/23/00, we granted stock options to purchase up to
8,339,539 shares of our common stock pursuant to our stock option plan, with a
weighted average exercise price of $2.31 per share. These issuances were exempt
from registration pursuant to Rule 701 under the Securities Act.

    In connection with our sale of $115,000,000 of 14% senior notes due 2008 to
qualified institutional buyers, in June 1998 we granted warrants to purchase up
to 1,409,734 shares of our common stock at an exercise price of $0.01 per share.
These issuances were exempt from registration pursuant to Section 4(2) of the
Securities Act.

    In March 1999, Mr. Jalkut, a member of our board of directors, agreed to
purchase 26,667 shares of our common stock for $200,000, and Mr. Ejabat, a
member of our board of directors, agreed to purchase 66,667 shares of our common
stock for $500,000.

ITEM 17. UNDERTAKINGS

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Securities Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the 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 issues.

    The undersigned Registrant hereby undertakes that:

        (1) 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 the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.

        (2) For 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.

                          CERTIFICATE OF INCORPORATION

                                       OF

                               BIRCH TELECOM, INC.

      BIRCH TELECOM, INC., a corporation organized and existing under the laws
of the State of Delaware, certifies as follows:

      1. The original Certificate of Incorporation of Birch Telecom, Inc. was
filed with the Delaware Secretary of State on December 23, 1996.

      2. This Restated Certificate of Incorporation amends and restates the
provisions of the Certificate of Incorporation of this Corporation, and was duly
adopted in accordance with Sections 245 and 228 of the General Corporation Law
of the State of Delaware by the directors and stockholders of the Corporation.

      3. The text of the Certificate of Incorporation is amended and restated to
read in its entirety as set forth below:

      First: The name of the Corporation is Birch Telecom, Inc. (the
"Corporation").

      Second: The address of the Corporation's initial registered office in the
State of Delaware is 1013 Centre Road, in the City of Wilmington, County of New
Castle, and the name of its initial registered agent at such address is the
Corporation Service Company.

      Third: The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the Delaware General
Corporation Law.

      Fourth:

A. The aggregate number of shares which the Corporation shall have authority to
issue shall be 135,000,000 shares, divided into 80,000,000 shares of common
stock ("Common Stock"), and 55,000,000 shares of preferred stock ("Preferred
Stock"). The Preferred Stock shall have a par value of one-tenth of one cent
($.001) each, and the Common Stock shall have a par value of one-tenth of one
cent ($.001) each.

B. The Preferred Stock may be issued from time to time in one or more series.
The Board of Directors is hereby authorized, within the limitations and
restrictions stated in this Restated Certificate of Incorporation, to fix or
alter the dividend rights, dividend rate, conversion rate, voting rights, rights
and terms of redemption (including sinking fund provisions), the redemption
price or prices, the liquidation preferences of any wholly unissued series of
Preferred Stock, and the number of shares constituting any such series and the
designation thereof, or any of them; and to increase or decrease the number of
shares of any series subsequent to the issue of shares of that series, but


                                       1
<PAGE>

not below the number of shares of such series then outstanding. In case the
number of shares of any series shall be so decreased, the shares constituting
such decrease shall resume the status which they had prior to the adoption of
the resolution originally fixing the number of shares of such series.

      Of the authorized shares of Preferred Stock, 8,750,000 shares are hereby
designated "Series B Preferred Stock"; 8,500,000 shares are hereby designated
"Series C Preferred Stock"; 3,000,000 shares are hereby designated "Series D
Preferred Stock"; 1,904,898 shares are hereby designated "Series E Preferred
Stock"; and 30,000,000 shares are hereby designated "Series F Preferred Stock."

C. The powers, preferences, rights, restrictions and other matters relating to
the Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
Stock, Series E Preferred Stock and Series F Preferred Stock are as follows:

            (1) Dividends.

            (a) Series B Preferred Stock. The holders of Series B Preferred
      Stock shall be entitled to receive dividends in cash at the rate of
      fifteen percent (15%) per annum on an amount equal to $1.52 plus all
      unpaid dividends accrued on such shares of Series B Preferred Stock, on
      each outstanding share of Series B Preferred Stock (as adjusted for any
      stock dividends, combinations, splits and the like with respect to such
      shares), when and as declared by the Board of Directors out of the funds
      legally available for that purpose. Such dividends shall be cumulative
      from the date of issuance of the Series B Preferred Stock, whether or not
      earned, whether or not funds of the Corporation are legally available for
      the payment of dividends and whether or not declared by the Board, but
      such dividends shall be payable only when, as, and if declared by the
      Board. So long as any shares of Series B Preferred Stock shall be
      outstanding, no dividend, whether in cash, stock or property, shall be
      paid or declared, nor shall any other distribution be made, on any shares
      of Series C Preferred Stock, Series D Preferred Stock, Series E Preferred
      Stock or Common Stock, nor shall more than 2,225,000 shares of Series C
      Preferred Stock or any shares of Series D Preferred Stock or Common Stock

      (except for acquisitions of Common Stock by the Corporation pursuant to
      agreements which permit the Corporation to repurchase such shares upon
      termination of services to the Corporation or in exercise of the
      Corporation's right of first refusal upon a proposed transfer) until all
      dividends set forth in this Section (1)(a) on the Series B Preferred Stock
      shall have been paid or declared and set apart.

            (b) Series C Preferred Stock. The holders of Series C Preferred
      Stock shall be entitled to receive dividends in cash at the rate of ten
      percent (10%) per annum on an amount equal to $1.52 on each outstanding
      share of Series C Preferred Stock (as adjusted for any stock dividends,
      combinations, splits and the like with respect to such shares), when and
      as declared by the Board of Directors out of funds legally available for
      that purpose. Notwithstanding anything to the contrary herein, such
      dividends shall be payable only when, as and if declared by the Board of
      Directors and shall not be cumulative. So long as any shares of Series C
      Preferred Stock shall be outstanding, no dividend, whether in cash, stock
      or property, shall be paid or declared, nor shall any other distribution
      be made, on any shares of Common Stock, nor shall any shares of Common
      Stock be purchased, redeemed or


                                       2
<PAGE>

      otherwise acquired for value by the Corporation (except for acquisitions
      of Common Stock by the Corporation pursuant to agreements which permit the
      Corporation to repurchase such shares upon termination of services to the
      Corporation or in exercise of the Corporation's right of first refusal
      upon a proposed transfer) until all dividends set forth in this Section

      and set apart.

            (c) Series D Preferred Stock. The holders of Series D Preferred
      Stock shall be entitled to receive dividends in cash at the rate of
      fifteen percent (15%) per annum on an amount equal to $4.50 plus all
      unpaid dividends accrued on such shares of Series D Preferred Stock, on
      each outstanding share of Series D Preferred Stock (as adjusted for any
      stock dividends, combinations, splits and the like with respect to such
      shares), when and as declared by the Board of Directors out of the funds
      legally available for that purpose. Such dividends shall be cumulative
      from the date of issuance of the Series D Preferred Stock, whether or not
      earned, whether or not funds of the Corporation are legally available for
      the payment of dividends and whether or not declared by the Board, but
      such dividends shall be payable only when, as, and if declared by the
      Board. So long as any shares of Series D Preferred Stock shall be
      outstanding, no dividend, whether in cash, stock or property, shall be
      paid or declared, nor shall any other distribution be made, on any shares
      of Series B Preferred Stock (other than in shares of Series E Preferred
      Stock), Series C Preferred Stock, Series E Preferred Stock or Common
      Stock, nor shall more than 2,225,000 shares of Series C Preferred Stock or
      any shares of Series B Preferred Stock or Common Stock be purchased,
      redeemed or otherwise acquired for value by the Corporation (except for
      acquisitions of Common Stock by the Corporation pursuant to agreements
      which permit the Corporation to repurchase such shares upon termination of
      services to the Corporation or in exercise of the Corporation's right of
      first refusal upon a proposed transfer) until all dividends set forth in
      this Section (1)(c) on the Series D Preferred Stock shall have been paid
      or declared and set apart.

            (d) Series E Preferred Stock. The holders of Series E Preferred
      Stock shall be entitled to receive dividends in cash at the rate of
      fifteen percent (15%) per annum on an amount equal to $4.50 plus all
      unpaid dividends accrued on such shares of Series E Preferred Stock, on
      each outstanding share of Series E Preferred Stock (as adjusted for any
      stock dividends, combinations, splits and the like with respect to such
      shares), when and as declared by the Board of Directors out of the funds
      legally available for that purpose. Such dividends shall be cumulative
      from the date of issuance of the Series E Preferred Stock, whether or not
      earned, whether or not funds of the Corporation are legally available for
      the payment of dividends and whether or not declared by the Board, but
      such dividends shall be payable only when, as, and if declared by the
      Board. So long as any shares of Series E Preferred Stock shall be
      outstanding, no dividend, whether in cash, stock or property, shall be
      paid or declared, nor shall any other distribution be made, on any shares
      of Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
      Stock or Common Stock, nor shall more than 2,225,000 shares of Series C
      Preferred Stock or any shares of Series B Preferred Stock, Series D
      Preferred Stock or Common Stock be purchased, redeemed or otherwise
      acquired for value by the Corporation (except for acquisitions of Common
      Stock by the Corporation pursuant to agreements which permit the
      Corporation to repurchase such shares upon termination of services to the
      Corporation or in exercise of the Corporation's


                                       3
<PAGE>

      right of first refusal upon a proposed transfer) until all dividends set
      forth in this Section (1)(d) on the Series E Preferred Stock shall have
      been paid or declared and set apart.

            (e) Series F Preferred Stock. The holders of Series F Preferred
      Stock shall be entitled to receive dividends in cash at the rate of
      fifteen percent (15%) per annum on an amount equal to the purchase price
      for such shares (the "Purchase Price") plus all unpaid dividends accrued
      on such shares of Series F Preferred Stock, on each outstanding share of
      Series F Preferred Stock (as adjusted for any stock dividends,
      combinations, splits and the like with respect to such shares), payable on
      March 31, June 30, September 30 and December 31 of each year, when and as
      declared by the Board of Directors out of the funds legally available for
      that purpose. Such dividends shall be cumulative from the date of issuance
      of the Series F Preferred Stock, whether or not earned, whether or not
      funds of the Corporation are legally available for the payment of
      dividends and whether or not declared by the Board, but such dividends
      shall be payable only when, as, and if declared by the Board. The Purchase
      Price for the Series F Preferred Stock is $4.50 per share for the initial
      purchase of 13,333,334 shares by BTI Ventures L.L.C. or its affiliates
      ("BTI"). In addition, BTI retains the option (the "Option") to acquire

      shall be paid or declared, nor shall any other distribution be made, on
      any shares of Series B Preferred Stock, Series C Preferred Stock, Series D
      Preferred Stock, Series E Preferred Stock, Common Stock or any other class
      or series of capital stock of the Corporation, nor shall more than
      2,225,000 shares of Series C Preferred or any shares of Series B Preferred
      Stock, Series D Preferred Stock, Common Stock or any other class or series
      of capital stock of the Corporation be purchased, redeemed or otherwise
      acquired for value by the Corporation (except for the redemption of the
      Series E Preferred Stock or acquisitions of Common Stock by the
      Corporation pursuant to agreements which permit the Corporation to
      repurchase such shares upon termination of services to the Corporation)
      until all dividends set forth in this Section (1)(e) on the Series F
      Preferred Stock shall have been paid or declared and set apart. In
      addition to the 15% quarterly dividend payable on the Series F Preferred
      Stock, the shares of Series F Preferred Stock shall be entitled to receive
      the amount of any cash or non-cash dividends or distributions declared and
      paid on the shares of Common Stock, as if the shares of Series F Preferred
      Stock had been converted immediately prior to the record date for the
      payment of such dividend or distribution.

            (2) Liquidation Rights.

            (a) Series F Preferred Stock. Upon any liquidation, dissolution, or
      winding up of the Corporation, and before any distribution or payment
      shall be made to the holders of Series B Preferred Stock, Series C
      Preferred Stock or Common Stock, the holders of Series F Preferred Stock
      shall be entitled to be paid out of the assets of the Corporation an
      amount equal to the greater of (i) the sum of (a) the applicable Purchase
      Price per share of Series F Preferred Stock (as adjusted for any stock
      dividends, combinations, splits and the like with respect to such shares)
      plus (b) an amount equal to all unpaid dividends accrued on such shares of
      Series F Preferred Stock to the date of payment of such preference,
      whether or not earned, whether or not funds of the Corporation are legally
      available for the payment of


                                       4
<PAGE>

      dividends and whether or not such dividends have been declared by the
      Board; or (ii) the amount the holders of Series F Preferred Stock would
      have received upon liquidation, dissolution or winding up of the
      Corporation had such shares of Series F Preferred Stock and all shares of

      the Company in which the gross proceeds to the Corporation (before
      underwriting discounts, commissions and fees) are at least $60,000,000.
      The number of shares of Common Stock to which a holder of Series B
      Preferred Stock shall be entitled upon conversion shall be the product
      obtained by multiplying the applicable Preferred Stock Rate then in effect
      by the number of shares of Series B Preferred Stock being converted by
      such holder. The number of shares of Common Stock to which a holder of
      Series C Preferred Stock shall be entitled upon conversion shall be the
      product obtained by multiplying the applicable Preferred Stock Rate then
      in effect by the number of shares of Series C Preferred Stock being
      converted by such holder. The number of shares of Common Stock to which a
      holder of Series D Preferred Stock shall be entitled upon conversion shall
      be the product obtained by multiplying the applicable Preferred Stock Rate
      then in effect by the number of shares of Series D Preferred Stock being
      converted by such holder. The number of shares of Common Stock to which a
      holder of Series E Preferred Stock shall be entitled upon conversion shall
      be the product obtained by multiplying the applicable Preferred Stock Rate
      then in effect by the number of shares of Series E Preferred Stock being
      converted by such holder. The number of shares of Common Stock to which a
      holder of Series F Preferred Stock shall be entitled upon conversion shall
      be the product obtained by multiplying the applicable Preferred Stock Rate
      then in effect by the


                                       11
<PAGE>

      number of shares of Series F Preferred Stock being converted by such
      holder.

            (c) Preferred Stock. The conversion rate of the applicable series of
      Preferred Stock in effect at any time for conversion of the Series B
      Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
      Series E Preferred Stock, or Series F Preferred Stock (the "Preferred
      Stock Rate") shall be the quotient obtained by dividing the Original Issue
      Price of the applicable series of Preferred Stock by the applicable
      Preferred Stock Price, calculated as provided in Section (4)(d). The
      "Original Issue Price" for the Series B Preferred Stock and Series C
      Preferred Stock shall initially equal $1.52 per share. The "Original Issue
      Price" of the Series D Preferred Stock and Series E Preferred Stock shall
      initially equal $4.50 per share. The "Original Issue Price" of the Series
      F Preferred Stock shall initially equal the Purchase Price with respect to
      each share.

            (d) Conversion Price. The conversion price for the applicable series
      of Preferred Stock shall initially be the Original Issue Price of the
      applicable series of Preferred Stock (the "Preferred Stock Price"). Such
      initial Preferred Stock Price shall be adjusted from time to time after
      the Series F Original Issue Date (as defined below) in accordance with
      this Section (4). All references to the Preferred Stock Price herein shall
      mean the Preferred Stock Price as applicable and as so adjusted.

            (e) Mechanics of Conversion. Each holder of Series B Preferred
      Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
      Preferred Stock, or Series F Preferred Stock who desires to convert the
      same into shares of Common Stock pursuant to this Section (4) shall
      surrender the certificate or certificates therefor, duly endorsed, at the
      office of the Corporation or any transfer agent for the Series B Preferred
      Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
      Preferred Stock, or Series F Preferred Stock, and shall give written
      notice to the Corporation at such office that such holder elects to
      convert the same. Such notice shall state the number of shares of Series B
      Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
      Series E Preferred Stock, or Series F Preferred Stock being converted.
      Thereupon, the Corporation shall promptly issue and deliver at such office
      to such holder a certificate or certificates for the number of shares of
      Common Stock to which such holder is entitled. Such conversion shall be
      deemed to have been made at the close of business on the date of such
      surrender of the certificates representing the shares of Series B
      Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
      Series E Preferred Stock, or Series F Preferred Stock to be converted, and
      the person entitled to receive the shares of Common Stock issuable upon
      such conversion shall be treated for all purposes as the record holder of
      such shares of Common Stock on such date.

            (f) Adjustment for Stock Splits and Combinations. If the Corporation
      shall at any time or from time to time after August 5, 1999 (the "Series F
      Original Issue Date") effect a subdivision of the outstanding Common Stock
      without a corresponding subdivision of the Series B Preferred Stock,
      Series C Preferred Stock, Series D Preferred Stock, Series E Preferred
      Stock, or Series F Preferred Stock, the Preferred Stock Price for each
      series of Preferred Stock in effect immediately before that subdivision
      shall be proportionately decreased. Conversely, if the Corporation shall
      at any time or from time to time after the Series F Original Issue Date
      combine the outstanding shares of Common Stock into a smaller number of
      shares without a corresponding combination of the Series B Preferred
      Stock, Series C Preferred Stock, Series


                                       12
<PAGE>

      D Preferred Stock, Series E Preferred Stock, or Series F Preferred Stock,
      the Preferred Stock Price for each series of Preferred Stock in effect
      immediately before the combination shall be proportionately increased. Any
      adjustment under this Section (4)(f) shall become effective at the close
      of business on the date the subdivision or combination becomes effective.

            (g) Adjustment for Common Stock Dividends and Distributions. If the
      Corporation at any time or from time to time makes, or fixes a record date
      for the determination of holders of Common Stock entitled to receive, a
      dividend or other distribution payable in additional shares of Common
      Stock, in each such event the Preferred Stock Price of each applicable
      series of Preferred Stock that is then in effect shall be decreased as of
      the time of such issuance or, in the event such record date is fixed, as
      of the close of business on such record date, by multiplying the Preferred
      Stock Price for each applicable series of Preferred Stock then in effect
      by a fraction (i) the numerator of which is the total number of shares of
      Common Stock issued and outstanding immediately prior to the time of such
      issuance or the close of business on such record date, and (ii) the
      denominator of which is the total number of shares of Common Stock issued
      and outstanding immediately prior to the time of such issuance or the
      close of business on such record date plus the number of shares of Common
      Stock issuable in payment of such dividend or distribution; provided,
      however, that if such record date is fixed and such dividend is not fully
      paid or if such distribution is not fully made on the date fixed therefor,
      the applicable Preferred Stock Price shall be recomputed accordingly as of
      the close of business on such record date and thereafter the applicable
      Preferred Stock Price shall be adjusted pursuant to this Section (4)(g) to
      reflect the actual payment of such dividend or distribution.

            (h) Adjustments for Other Dividends and Distributions. If the
      Corporation at any time or from time to time makes, or fixes a record date
      for the determination of holders of Common Stock entitled to receive, a
      dividend or other distribution payable in securities of the Corporation
      other than shares of Common Stock, in each such event provision shall be
      made so that the holders of the Series B Preferred Stock, Series C
      Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and
      Series F Preferred Stock shall receive upon conversion thereof, in
      addition to the number of shares of Common Stock receivable thereupon, the
      amount of other securities of the Corporation which they would have
      received had their Series B Preferred Stock, Series C Preferred Stock,
      Series D Preferred Stock, Series E Preferred Stock, or Series F Preferred
      Stock been converted into Common Stock on the date of such event and had
      they thereafter, during the period from the date of such event to and
      including the conversion date, retained such securities receivable by them
      as aforesaid during such period, subject to all other adjustments called
      for during such period under this Section (4)(h) with respect to the
      rights of the holders of the Preferred Stock or with respect to such other
      securities by their terms.

            (i) Adjustment for Reclassification, Exchange and Substitution. If
      at any time or from time to time after the Series F Original Issue Date,
      the Common Stock issuable upon the conversion of the Series B Preferred
      Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
      Preferred Stock and Series F Preferred Stock is changed into the same or a
      different number of shares of any class or classes of stock, whether by
      recapitalization, reclassification or otherwise (other than an Acquisition
      or Asset Transfer as defined in Section (2)(g) or a subdivision or
      combination of shares or stock dividend or a reorganization, merger,
      consolidation or sale of assets provided for elsewhere in this Section
      (4)), in any such event


                                       13
<PAGE>

      each holder of Series B Preferred Stock, Series C Preferred Stock, Series
      D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock
      shall have the right thereafter to convert such stock into the kind and
      amount of stock and other securities and property receivable upon such
      recapitalization, reclassification or other change by holders of the
      maximum number of shares of Common Stock into which such shares of Series
      B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
      Series E Preferred Stock, or Series F Preferred Stock could have been
      converted immediately prior to such recapitalization, reclassification or
      change, all subject to further adjustment as provided herein or with
      respect to such other securities or property by the terms thereof.

            (j) Reorganizations, Mergers, Consolidations or Sales of Assets. If
      at any time or from time to time after the Series F Original Issue Date,
      there is a capital reorganization of the Common Stock, merger,
      consolidation or sale of assets (other than an Acquisition or Asset
      Transfer as defined in Section (2)(g) or a recapitalization, subdivision,
      combination, reclassification, exchange or substitution of shares provided
      for elsewhere in this Section (4)), as a part of such capital
      reorganization, merger, consolidation or sale of assets, provision shall
      be made so that the holders of the Series B Preferred Stock, Series C
      Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and
      Series F Preferred Stock shall thereafter be entitled to receive upon
      conversion of the Series B Preferred Stock, Series C Preferred Stock,
      Series D Preferred Stock, Series E Preferred Stock and Series F Preferred
      Stock the number of shares of stock or other securities or property of the
      Corporation or third party entity to which a holder of the number of
      shares of Common Stock deliverable upon conversion would have been
      entitled on such capital reorganization, merger, consolidation or sale of
      assets, subject to adjustment in respect of such stock or securities by
      the terms thereof. In any such case, appropriate adjustment shall be made
      in the application of the provisions of this Section (4) with respect to
      the rights of the holders of Series B Preferred Stock, Series C Preferred
      Stock, Series D Preferred Stock, Series E Preferred Stock and Series F
      Preferred Stock after the capital reorganization, merger, consolidation or
      sale of assets to the end that the provisions of this Section (4)
      (including adjustment of the Preferred Stock Price then in effect and the
      number of shares issuable upon conversion of the Series B Preferred Stock,
      Series C Preferred Stock, Series D Preferred Stock, Series E Preferred
      Stock and Series F Preferred Stock) shall be applicable after that event
      and be as nearly equivalent as practicable.

            (k) Sale of Shares Below Preferred Stock Price.

                  (i) If at any time or from time to time after the Series F
            Original Issue Date, the Corporation issues or sells, or is deemed
            by the express provisions of this Section (4)(k) to have issued or
            sold, Additional Shares of Common Stock (as defined in Section
            (4)(k)(iv) below), other than as a dividend or other distribution on
            any class of stock as provided in Section (4)(g) above, and other
            than a subdivision or combination of shares of Common Stock as
            provided in Section (4)(f) above, for an Effective Price (as defined
            in Section (4)(k)(iv) below) less than the then effective Preferred
            Stock Price with respect to the applicable series of Preferred
            Stock, then and in each such case the then existing Preferred Stock
            Price with respect to the applicable series of Preferred Stock shall
            be reduced, as of the opening of business on the date of such issue
            or sale, to a price determined by multiplying the applicable
            Preferred Stock Price by a fraction (i) the numerator of which shall
            be (A) the number of shares of Common Stock


                                       14
<PAGE>

            deemed outstanding (as defined below) immediately prior to such
            issue or sale, plus (B) the number of shares of Common Stock which
            the aggregate consideration received (as defined in Section
            (4)(k)(ii) below) by the Corporation for the total number of
            Additional Shares of Common Stock so issued would purchase at such
            applicable Preferred Stock Price, and (ii) the denominator of which
            shall be the number of shares of Common Stock deemed outstanding (as
            defined below) immediately prior to such issue or sale plus the
            total number of Additional Shares of Common Stock so issued. For the
            purposes of the preceding sentence, the number of shares of Common
            Stock deemed to be outstanding as of a given date shall be the sum
            of (A) the number of shares of Common Stock actually outstanding,
            (B) the number of shares of Common Stock into which the then
            outstanding shares of Series B Preferred Stock, Series C Preferred
            Stock, Series D Preferred Stock, Series E Preferred Stock and Series
            F Preferred Stock could be converted if fully converted on the day
            immediately preceding the given date, and (C) the number of shares
            of Common Stock which could be obtained through the exercise or
            conversion of all other rights, options and convertible securities
            on the day immediately preceding the given date.

                  (ii) For the purpose of making any adjustment required under
            this Section (4)(k), the consideration received by the Corporation
            for any issue or sale of securities shall (A) to the extent it
            consists of cash, be computed at the net amount of cash received by
            the Corporation after deduction of any underwriting or similar
            commissions, compensation or concessions paid or allowed by the
            Corporation in connection with such issue or sale but without
            deduction of any expenses payable by the Corporation, (B) to the
            extent it consists of property other than cash, be computed at the
            fair value of that property as determined in good faith by the Board
            of Directors, and (C) if Additional Shares of Common Stock,
            Convertible Securities (as defined in Section (4)(k)(iii) below) or
            rights or options to purchase either Additional Shares of Common
            Stock or Convertible Securities are issued or sold together with
            other stock or securities or other assets of the Corporation for a
            consideration which covers both, be computed as the portion of the
            consideration so received that may be reasonably determined in good
            faith by the Board of Directors to be allocable to such Additional
            Shares of Common Stock, Convertible Securities or rights or options.

                  (iii) For the purpose of the adjustment required under this
            Section (4)(k), if the Corporation issues or sells any rights or
            options for the purchase of, or stock or other securities
            convertible into, Additional Shares of Common Stock (such
            convertible stock or securities being herein referred to as
            "Convertible Securities") and if the Effective Price of such
            Additional Shares of Common Stock is less than the applicable
            Preferred Stock Price, in each case the Corporation shall be deemed
            to have issued at the time of the issuance of such rights or options
            or Convertible Securities the maximum number of Additional Shares of
            Common Stock issuable upon exercise or conversion thereof and to
            have received as consideration for the issuance of such shares an
            amount equal to the total amount of the consideration, if any,
            received by the Corporation for the issuance of such rights or
            options or Convertible Securities, plus, in the case of such rights
            or options, the minimum amounts of consideration, if any, payable to
            the Corporation upon the exercise of such rights or options, plus,
            in the case of Convertible Securities, the minimum amounts of
            consideration, if any, payable to the Corporation


                                       15
<PAGE>

            (other than by cancellation of liabilities or obligations evidenced
            by such Convertible Securities) upon the conversion thereof;
            provided that if in the case of Convertible Securities the minimum
            amounts of such consideration cannot be ascertained, but are a
            function of antidilution or similar protective clauses, the
            Corporation shall be deemed to have received the minimum amounts of
            consideration without reference to such clauses; provided further
            that if the minimum amount of consideration payable to the
            Corporation upon the exercise or conversion of rights, options or
            Convertible Securities is reduced over time or on the occurrence or
            non-occurrence of specified events other than by reason of
            antidilution adjustments, the Effective Price shall be recalculated
            using the figure to which such minimum amount of consideration is
            reduced; provided further that if the minimum amount of
            consideration payable to the Corporation upon the exercise or
            conversion of such rights, options or Convertible Securities is
            subsequently increased, the Effective Price shall be again
            recalculated using the increased minimum amount of consideration
            payable to the Corporation upon the exercise or conversion of such
            rights, options or Convertible Securities. No further adjustment of
            the applicable Preferred Stock Price, as adjusted upon the issuance
            of such rights, options or Convertible Securities, shall be made as
            a result of the actual issuance of Additional Shares of Common Stock
            on the exercise of any such rights or options or the conversion of
            any such Convertible Securities. If any such rights or options or
            the conversion privilege represented by any such Convertible
            Securities shall expire without having been exercised, the
            applicable Preferred Stock Price as adjusted upon the issuance of
            such rights, options or Convertible Securities shall be readjusted
            to the applicable Preferred Stock Price which would have been in
            effect had an adjustment been made on the basis that the only
            Additional Shares of Common Stock so issued were the Additional
            Shares of Common Stock, if any, actually issued or sold on the
            exercise of such rights or options or rights of conversion of such
            Convertible Securities, and such Additional Shares of Common Stock,
            if any, were issued or sold for the consideration actually received
            by the Corporation upon such exercise, plus the consideration, if
            any, actually received by the Corporation for the granting of all
            such rights or options, whether or not exercised, plus the
            consideration received for issuing or selling the Convertible
            Securities actually converted, plus the consideration, if any,
            actually received by the Corporation (other than by cancellation of
            liabilities or obligations evidenced by such Convertible Securities)
            on the conversion of such Convertible Securities, provided that such
            readjustment shall not apply to prior conversions of Series B
            Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
            Series E Preferred Stock, or Series F Preferred Stock.

                  (iv) "Additional Shares of Common Stock" shall mean all shares
            of Common Stock issued by the Corporation or deemed to be issued
            pursuant to this Section (4)(k), whether or not subsequently
            reacquired or retired by the Corporation other than (A) shares of
            Series E Preferred Stock,; (B) shares of Common Stock issued upon
            conversion of the Series B Preferred Stock, Series C Preferred
            Stock, Series D Preferred Stock, Series E Preferred Stock, or Series
            F Preferred Stock; (C) Common Stock and/or options, warrants or
            other Common Stock purchase rights, and the Common Stock issued
            pursuant to such options, warrants or other rights to employees,
            officers or directors of, or consultants or advisors to the
            Corporation or any subsidiary


                                       16
<PAGE>

            pursuant to stock purchase or stock option plans or other
            arrangements that are approved by the Board; (D) shares of Common
            Stock issued pursuant to the exercise of options, warrants or
            convertible securities outstanding as of the Series F Original Issue
            Date; and (E) warrants to purchase Common Stock, and the Common
            Stock issued pursuant to such warrants, that are issued to holders
            of the Senior Notes due 2008 issued by the Corporation pursuant to
            an indenture between the Corporation and Norwest Bank, N.A. (the
            "Senior Notes"). The "Effective Price" of Additional Shares of
            Common Stock shall mean the quotient determined by dividing the
            total number of Additional Shares of Common Stock issued or sold, or
            deemed to have been issued or sold by the Corporation under this
            Section (4)(k), into the aggregate consideration received, or deemed
            to have been received by the Corporation for such issue under this
            Section (4)(k), for such Additional Shares of Common Stock.

            (l) Certificate of Adjustment. In each case of an adjustment or
      readjustment of the applicable Preferred Stock Price for the number of
      shares of Common Stock or other securities issuable upon conversion of the
      Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
      Stock, Series E Preferred Stock, or Series F Preferred Stock, if the
      Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
      Stock, Series E Preferred Stock, or Series F Preferred Stock is then
      convertible pursuant to this Section (4), the Corporation, at its expense,
      shall compute such adjustment or readjustment in accordance with the
      provisions hereof and prepare a certificate showing such adjustment or
      readjustment, and shall mail such certificate, by first class mail,
      postage prepaid, to each registered holder of Series B Preferred Stock,
      Series C Preferred Stock, Series D Preferred Stock, Series E Preferred
      Stock, or Series F Preferred Stock at the holder's address as shown in the
      Corporation's books. The certificate shall set forth such adjustment or
      readjustment, showing in detail the facts upon which such adjustment or
      readjustment is based, including a statement of (i) the consideration
      received or deemed to be received by the Corporation for any Additional
      Shares of Common Stock issued or sold or deemed to have been issued or
      sold, (ii) the Preferred Stock Price at the time in effect, (iii) the
      number of Additional Shares of Common Stock and (iv) the type and amount,
      if any, of other property which at the time would be received upon
      conversion of the Series B Preferred Stock, Series C Preferred Stock,
      Series D Preferred Stock, Series E Preferred Stock, or Series F Preferred
      Stock.

            (m) Notices of Record Date. Upon (i) any taking by the Corporation
      of a record of the holders of any class of securities for the purpose of
      determining the holders thereof who are entitled to receive any dividend
      or other distribution, or (ii) any Acquisition (as defined in Section
      (2)(g)) or other capital reorganization of the Corporation, any
      reclassification or recapitalization of the capital stock of the
      Corporation, any merger or consolidation of the Corporation with or into
      any other corporation, or any Asset Transfer (as defined in Section
      (2)(g)), or any voluntary or involuntary dissolution, liquidation or
      winding up of the Corporation, the Corporation shall mail to each holder
      of Preferred Stock at least twenty (20) calendar days prior to the record
      date specified therein a notice specifying (A) the date on which any such
      record is to be taken for the purpose of such dividend or distribution and
      a description of such dividend or distribution, (B) the date on which any
      such Acquisition, reorganization, reclassification, transfer,
      consolidation, merger, Asset Transfer, dissolution, liquidation or winding
      up is expected to become effective, and (C) the date, if any, that is to
      be fixed as to when the holders of record of Common Stock (or other
      securities) shall be entitled


                                       17
<PAGE>

      to exchange their shares of Common Stock (or other securities) for
      securities or other property deliverable upon such Acquisition,
      reorganization, reclassification, transfer, consolidation, merger, Asset
      Transfer, dissolution, liquidation or winding up.

            (n) Fractional Shares. No fractional shares of Common Stock shall be
      issued upon conversion of Series B Preferred Stock, Series C Preferred
      Stock, Series D Preferred Stock, Series E Preferred Stock, or Series F
      Preferred Stock. All shares of Common Stock (including fractions thereof)
      issuable upon conversion of more than one share of Series B Preferred
      Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
      Preferred Stock, or Series F Preferred Stock by a holder thereof shall be
      aggregated for purposes of determining whether the conversion would result
      in the issuance of any fractional share. If, after the aforementioned
      aggregation, the conversion would result in the issuance of any fractional
      share, the Corporation shall, in lieu of issuing any fractional share, pay
      cash equal to the product of such fraction multiplied by the Common
      Stock's fair market value (as determined in accordance with Section
      (2)(i)) on the date of conversion.

            (o) Reservation of Stock. The Corporation shall at all times reserve
      and keep available out of its authorized but unissued shares of Common
      Stock such number of its shares of Common Stock as shall from time to time
      be sufficient to effect the conversion of all outstanding shares of Series
      B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
      Series E Preferred Stock and Series F Preferred Stock and the exercise of
      all outstanding options and warrants of the Corporation. If at any time
      the number of authorized but unissued shares of Common Stock shall not be
      sufficient to effect the conversion of all then outstanding shares of the
      Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
      Stock, Series E Preferred Stock and Series F Preferred Stock or the
      exercise of all outstanding options and warrants, the Corporation will
      take such corporate action as may, in the opinion of its counsel, be
      necessary to increase its authorized but unissued shares of Common Stock
      to such number of shares as shall be sufficient for such purposes.

            (p) Notices. Any notice required by the provisions of this Section
      (4) shall be in writing and shall be deemed effectively given: (i) upon
      personal delivery to the party to be notified, (ii) when sent by confirmed
      telex or facsimile if sent during normal business hours of the recipient;
      if not, then on the next business day, (iii) five (5) business days after
      having been sent by registered or certified mail, return receipt
      requested, postage prepaid, or (iv) one (1) business day after deposit
      with a nationally recognized overnight courier, specifying next day
      delivery, with written verification of receipt. All notices shall be
      addressed to each holder of record at the address of such holder appearing
      on the books of the Corporation.

            (q) Payment of Taxes. The Corporation will pay all taxes (other than
      taxes based upon income) and other governmental charges that may be
      imposed with respect to the issue or delivery of shares of Common Stock
      upon conversion of shares of Series B Preferred Stock, Series C Preferred
      Stock, Series D Preferred Stock, Series E Preferred Stock, or Series F
      Preferred Stock, excluding any tax or other charge imposed in connection
      with any transfer involved in the issue and delivery of shares of Common
      Stock in a name other than that in which the shares of Series B Preferred
      Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
      Preferred Stock, or Series F Preferred Stock so converted were registered.

      (5) Redemption.

      (a) Series F Preferred Stock.

            (i) Generally. In the event of (a) a breach by the Corporation of
      any of the terms of this Restated Certificate of Incorporation, the Bylaws
      of the Corporation, or the Amended and Restated Purchaser's Rights
      Agreement, dated July 2, 1999 by and among the Corporation and certain
      holders of its capital stock, as the same may be amended from time to time
      (including in connection with the issuance of Series F Preferred Stock),
      which has a material adverse effect on the holders of the Series F
      Preferred Stock that is not cured within fifteen (15) days of receipt of
      written notice by the Corporation from a holder of Series F Preferred
      Stock, or (b) the voluntary resignation (other than due to death or
      disability) prior to February 10, 2001 of (i) David E. Scott or (ii) any
      two of Jeffrey D. Shackelford, Bradley A. Moline, or Gregory C. Lawhon
      within six (6) months of one another (in the case of (a) or (b), a
      "Redemption Event"), a majority in interest of the Series F Preferred
      Stock may elect to demand in writing ("Redemption Demand") the redemption
      of all or any portion of the shares of Series F Preferred Stock, from any
      source of funds legally available therefor, at a redemption price per
      share (the "Series F Redemption Price") equal to the amount of the Series
      F Liquidation Preference. The redemption under this Section (5)(a) shall
      take place on a date (the "Series F Redemption Date") that is no later
      than thirty (30) days after the receipt by the Corporation of the
      Redemption Demand.

            (ii) Indenture Restriction. Notwithstanding the foregoing, the
      Corporation shall not be obligated to redeem the shares of Series F
      Preferred Stock for cash pursuant to Section (5)(a)(i), if such redemption
      or the existence of the redemption provision would violate the terms of
      the Indenture, dated as of June 23, 1998, by and between the Corporation
      and Norwest Bank Minnesota, National Association (as trustee), as amended,
      pursuant to which the Senior Notes were issued, until 91 days after the
      date on which the Senior Notes mature. If the Corporation is unable to
      redeem the Series F Preferred Stock for cash as set forth above, a
      majority in interest of the Series F Preferred Stock may elect to receive
      shares of Common Stock with a fair market value (as determined in
      accordance with Section (2)(i)) equal to the Series F Redemption Price.

            (iii) Procedure. At least 15 days prior to a Series F Redemption
      Date, written notice shall be mailed, first class postage prepaid, to each
      holder of record (at the close of business on the business day next
      preceding the day on which notice is given) of the Series F Preferred
      Stock to be redeemed, at the address last shown on the records of the
      Corporation for such holder, notifying such holder of the redemption to be
      effected, specifying the number of shares to be redeemed from such holder,
      the Series F Redemption Date, the Series F Redemption Price, whether or
      not the Corporation may redeem the shares for cash, or if not, the number
      of shares of Common Stock issuable in lieu of cash as set forth in Section
      (5)(a)(ii) above, the place at which payment or delivery may be obtained
      and calling upon such holder to surrender to the Corporation, in the
      manner and at the place designated, his


                                       19
<PAGE>

      certificate or certificates representing the shares to be redeemed (the
      "Series F Company Redemption Notice"). Except as provided in Section
      (5)(c), on or after the applicable Series F Redemption Date, each holder
      of Series F Preferred Stock to be redeemed shall surrender to the
      Corporation the certificate or certificates representing such shares, in
      the manner and at the place designated in the Series F Redemption Notice,
      and thereupon the Series F Redemption Price of such shares (in cash or
      shares of Common Stock, as applicable) shall be payable to the order of
      the person whose name appears on such certificate or certificates as the
      owner thereof and each surrendered certificate shall be canceled. In the
      event less than all the shares represented by any such certificate are
      redeemed, a new certificate shall be issued representing the unredeemed
      shares.

            (iv) Deposit of Redemption Price or Shares of Common Stock. Subject
      to the provisions set forth above, on or prior to each Series F Redemption
      Date, the Corporation shall deposit the Series F Redemption Price of all
      shares of Series F Preferred Stock designated for redemption in the Series
      F Redemption Notice and not yet redeemed with a bank or trust corporation
      as a trust fund for the benefit of the respective holder or holders of the
      shares designated for redemption and not yet redeemed, with irrevocable
      instructions and authority to the bank or trust corporation to pay the
      Series F Redemption Price for such shares to their respective holder or
      holders on or after the applicable Series F Redemption Date upon receipt
      of notification from the Corporation that such holder has surrendered his
      share certificate to the Corporation pursuant to Section (5)(a)(iii). As
      of the applicable Series F Redemption Date, the deposit shall constitute
      full payment of the shares to the holder or holders, and from and after
      the applicable Series F Redemption Date the shares so called for
      redemption shall be redeemed and shall be deemed to be no longer
      outstanding, and the holder or holders thereof shall cease to be
      stockholders with respect to such shares and shall have no rights with
      respect thereto except the rights to receive from the bank or trust
      corporation payment of the Series F Redemption Price of the shares,
      without interest, upon surrender of their certificates therefor. The
      balance of any moneys deposited by the Corporation pursuant to this
      Section (5)(a)(iv) remaining unclaimed at the expiration of two years
      following the applicable Series F Redemption Date shall thereafter be
      returned to the Corporation upon its request expressed in a resolution of
      its Board of Directors. In the event that the Corporation must issue new
      shares of Common Stock instead of cash pursuant to the provisions set
      forth in Section (5)(a)(ii), shares of Common Stock shall be delivered to
      the bank or trust corporation in lieu of such cash.

      (b) Series E Preferred Stock.

            (i) Generally. The Corporation, at any time and from time to time
      (each a "Series E Redemption Date"), may redeem all or any portion of the
      shares of Series E Preferred Stock, from any source of funds legally
      available therefor, at a redemption price per share (the "Series E
      Redemption Price") equal to (A) $4.50 per share for shares of Series E
      Preferred Stock redeemed pursuant to a Series E Redemption Date occurring
      on or before October 1, 1999, or (B) the Series E Liquidation Preference
      for shares of Series E Preferred Stock redeemed pursuant to


                                       20
<PAGE>

      a Series E Redemption Date occurring after October 1, 1999.

            (ii) Procedure. On each Series E Redemption Date, written notice
      shall be mailed, first class postage prepaid, to each holder of record (at
      the close of business on the business day next preceding the day on which
      notice is given) of the Series E Preferred Stock to be redeemed, at the
      address last shown on the records of the Corporation for such holder,
      notifying such holder of the redemption to be effected, specifying the
      number of shares to be redeemed from such holder, the Series E Redemption
      Date and the Series E Redemption Price (the "Series E Company Redemption
      Notice").

            (iii) Deposit of Redemption Price. As of the applicable Series E
      Redemption Date, the Corporation shall deposit the Series E Redemption
      Price of all shares of Series E Preferred Stock designated for redemption
      in the Series E Redemption Notice with a bank or trust corporation as a
      trust fund for the benefit of the respective holder or holders of the
      shares designated for redemption, with irrevocable instructions and
      authority to the bank or trust corporation to pay to the holders of record
      of the Series E Preferred Stock to be redeemed As of the applicable Series
      E Redemption Date, the deposit shall constitute full payment of the shares
      to the holder or holders, and from and after the applicable Series E
      Redemption Date the shares so called for redemption shall be redeemed and
      shall be deemed to be no longer outstanding, and the holder or holders
      thereof shall cease to be stockholders with respect to such shares and
      shall have no rights with respect thereto except the rights to receive
      from the bank or trust corporation payment of the Series E Redemption
      Price of the shares, without interest. The balance of any moneys deposited
      by the Corporation pursuant to this Section (5)(b)(iii) remaining
      unclaimed at the expiration of two years following the applicable Series E
      Redemption Date shall thereafter be returned to the Corporation upon its
      request expressed in a resolution of its Board of Directors.

      (c) Rights of Redeemed Stock; Default.

            (i) From and after the applicable Redemption Date, unless there
      shall have been a default in payment of the applicable Redemption Price
      (in cash or shares of Common Stock, as applicable), all rights of the
      holders of shares of Preferred Stock designated for redemption in the
      Company Redemption Notice as holders of Series E Preferred Stock or Series
      F Preferred Stock, as applicable (except the right to receive the
      applicable Redemption Price without interest upon surrender of their
      certificate or certificates) shall cease with respect to such shares, and
      such shares shall not thereafter be transferred on the books of the
      Corporation or be deemed to be outstanding for any purpose whatsoever.

            (ii) If the Corporation fails to redeem for any reason, including,
      but not limited to, the insufficiency of funds legally available for the
      redemption of shares, the total number of shares of Preferred Stock to be
      redeemed on such Redemption Date, those funds which are legally available
      will be used to redeem the maximum possible number of such shares ratably
      among the holders of such shares to be


                                       21
<PAGE>

            redeemed based upon their holdings of Series E Preferred Stock or
            Series F Preferred Stock, as applicable. The shares of Preferred
            Stock not redeemed shall remain outstanding and be entitled to all
            the rights and preferences provided herein or, with respect to the
            Series F Preferred Stock, may be otherwise converted into shares of
            Common Stock pursuant to the provisions set forth in Section
            (5)(a)(ii). At any time thereafter when additional funds of the
            Corporation are legally available for the redemption such shares of
            Preferred Stock such funds will immediately be used to redeem the
            balance of the shares which the Corporation has become obliged to
            redeem on any applicable Redemption Date, but which it has not
            redeemed.

            (6) Increasing Common Stock. Subject to the provisions of this
      Restated Certificate of Incorporation, the number of authorized shares of
      Common Stock may be increased or decreased (but not below the number of
      shares of Common Stock then outstanding, issuable upon the conversion of
      the Series B Preferred Stock, Series C Preferred Stock, Series D Preferred
      Stock, Series E Preferred Stock, Series F Preferred Stock and any other
      convertible securities of the Corporation, and issuable upon the exercise
      of all outstanding options and warrants), by the affirmative vote of the
      holders of a majority of the Common Stock and Preferred Stock, voting
      together as a single class.

            (7) No Reissuance of Series B Preferred Stock, Series C Preferred
      Stock, Series D Preferred Stock, Series E Preferred Stock or Series F
      Preferred Stock. No share or shares of Series B Preferred Stock, Series C
      Preferred Stock, Series D Preferred Stock, Series E Preferred Stock, or
      Series F Preferred Stock acquired by the Corporation by reason of
      redemption, purchase, or otherwise shall be reissued, and all such shares
      shall be canceled, retired and eliminated from the shares which the
      Corporation shall be authorized to issue.

      Fifth: The number of directors which shall constitute the whole Board of
Directors of the Corporation shall be no less than seven (7) nor more than
eleven (11), which number shall be fixed by the Board of Directors of the
Corporation from time to time.

      Sixth: The Board of Directors shall have power to make, and from time to
time alter, amend, or repeal the Bylaws of the Corporation; provided, however,
that (a) the stockholders shall have the paramount power to alter, amend and
repeal the Bylaws or adopt new Bylaws, exercisable by a majority vote of the
stockholders present in person or by proxy at any annual or special meeting of
stockholders, and (b) if and to the extent the stockholders exercise such power,
the Board of Directors shall not thereafter suspend, alter, amend or repeal the
Bylaws, or portions thereof, adopted by the stockholders, unless, in adopting
such Bylaws, or portions thereof, the stockholders otherwise provide.

      Seventh: A director of the Corporation shall not be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (a) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (b) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (c) under the provisions of Section 174 of the Delaware
General Corporation Law and


                                       22
<PAGE>

amendments thereto, or (d) for any transaction from which the director derived
an improper personal benefit. If the Delaware General Corporation Law is amended
to authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Corporation
shall be eliminated or limited to the fullest extent permitted by the Delaware
General Corporation Law, as so amended. No amendment, repeal or adoption of any
provision of this Restated Certificate of Incorporation inconsistent with this
Article Seventh shall apply or have any effect on the liability of any director
of the Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment, repeal, or adoption of any inconsistent
provision.

      Eighth: The directors of the Corporation need not be elected by written
ballot.

      Ninth:

      (a) Subject only to the exclusions set forth in paragraph (c) of this
Article Ninth, the Corporation shall hold harmless and indemnify, to the fullest
extent permitted by applicable law as it presently exists or may hereafter be
amended, each director or officer of the Corporation (each, an "Indemnitee")
against any and all liability and loss suffered and expenses (including
attorneys' fees), judgments, fines, excise taxes assessed with respect to any
employee benefit plan, or penalties and amounts paid in settlement actually and
reasonably incurred by Indemnitee in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (including an action by or in the right of the Corporation), to
which Indemnitee is, was or at any time becomes a party, or is threatened to be
made a party, by reason of the fact that Indemnitee is, was or at any time
becomes a director or officer of the Corporation, or is, or was serving, or at
any time serves at the request of the Corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise.

      (b) The expenses (including attorneys' fees) actually and reasonably
incurred by Indemnitee in defending any proceeding and any judgments, fines or
amounts to be paid in settlement shall be advanced by the Corporation at the
request of the Indemnitee and upon delivery to the Corporation of an undertaking
by such Indemnitee to repay all amounts so advanced if it shall ultimately be
determined that Indemnitee was not entitled to be indemnified or was not to be
fully indemnified.

      (c) No indemnity pursuant to this Article Ninth shall be paid by the
Corporation (i) for which payment is actually made to Indemnitee under a valid
and collectible insurance policy, except in respect of any excess beyond the
amount of payment under such insurance; (ii) for which Indemnitee is indemnified
by the Corporation pursuant to applicable law or otherwise than pursuant to this
Article Ninth; (iii) for an accounting of profits made from the purchase or sale
by Indemnitee of securities of the Corporation within the meaning of Section
16(b) of the Securities Exchange Act of 1934 and amendments thereto or similar
provisions of any state statutory law or common law; (iv) on account of
Indemnitee's conduct which is finally adjudged by a court to have been knowingly
fraudulent, deliberately dishonest or willful misconduct; or (v) if a final
decision by a court having jurisdiction in the matter shall determine that such
indemnity is not lawful.


                                       23
<PAGE>

      (d) All obligations of the Corporation contained herein shall continue
during the period Indemnitee is a director or officer of the Corporation (or is,
or was serving at the request of the Corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise) and
shall continue thereafter so long as Indemnitee shall be subject to any possible
claim or threatened, pending or completed action, suit or proceeding, whether
civil, criminal or investigative, by reason of the fact that Indemnitee was a
director or officer of the Corporation or serving in any other capacity referred
to herein.

      (e) Promptly after receipt by Indemnitee of notice of the commencement of
any action, suit or proceeding, Indemnitee will, if a claim in respect thereof
is to be made against the Corporation under this Article Ninth, notify the
Corporation of the commencement thereof; but the omission so to notify the
Corporation will not relieve it from any liability which it may have to
Indemnitee otherwise than under this Article Ninth. With respect to any such
action, suit or proceeding as to which Indemnitee notifies the Corporation of
the commencement thereof, the Corporation will be entitled to participate
therein at its own expense.

      (f) Except as otherwise provided below, to the extent that it may wish,
the Corporation jointly with any other indemnifying party similarly notified
will be entitled to assume the defense thereof with counsel reasonably
satisfactory to the Indemnitee. After notice from the Corporation to Indemnitee
of its election so to assume the defense thereof, the Corporation will not be
liable to Indemnitee under this Article Ninth for any legal or other expenses
subsequently incurred by Indemnitee in connection with the defense thereof other
than reasonable costs of investigation or as otherwise provided below.
Indemnitee shall have the right to employ its counsel in such action, suit or
proceeding, but the fees and expenses of such counsel, incurred after notice
from the Corporation of its assumption of the defense thereof, shall be at the
expense of Indemnitee unless (i) the employment of counsel by Indemnitee has
been authorized by the Corporation, (ii) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Corporation and
Indemnitee in the conduct of the defense of such, subject to the approval of the
Corporation, which approval shall not be unreasonably withheld, or (iii) the
Corporation shall not in fact have employed counsel to assume the defense of
such action, in each of which cases the fees and expenses of counsel shall be at
the expense of the Corporation. The Corporation shall not be entitled to assume
the defense of any action, suit or proceeding brought by or on behalf of the
Corporation or as to which Indemnitee shall have made the conclusion provided
for in (ii) above.

      (g) The Corporation shall not be liable to indemnify Indemnitee under this
Article Ninth for any amounts paid in settlement of any action or claim effected
without its written consent. The Corporation shall not settle any action or
claim in any manner which would impose any penalty or limitation on Indemnitee
without Indemnitee's written consent. Neither the Corporation nor Indemnitee
will unreasonably withhold their consent to any proposed settlement.

      (h) In the event Indemnitee is required to bring any action to enforce
rights or to collect moneys due under this Article Ninth and is successful in
such action, the Corporation shall promptly


                                       24
<PAGE>

reimburse Indemnitee for all of Indemnitee's reasonable fees and expenses in
bringing and pursuing such action.

      (i) The provisions of this Article Ninth shall inure to the benefit of and
be enforceable by the Indemnitee's personal or legal representatives, executors,
administrators, heirs, devises and legatees.

      (j) The Corporation shall have power to purchase and maintain insurance,
at its expense, on behalf of any person who is or was an officer, director,
employee or agent of the Corporation or a subsidiary thereof, or is or was
serving at the request of the Corporation as an officer, director, partner,
member, employee, trustee or agent of another corporation, partnership, joint
venture, trust or other enterprise, including any employee benefit plan, against
any expense, liability or loss asserted against such person and incurred by such
person in any such capacity, or arising out of such person's status as such,
whether or not the Corporation would have the power to indemnify such person
against such expense, liability or loss under the Bylaws, the provisions of this
Article Ninth or the Delaware General Corporation Law.

      (k) The indemnification provided by this Article Ninth shall not be deemed
exclusive of any other rights to which a person seeking indemnification may be
entitled under any statute, the Bylaws, other provisions of this Restated
Certificate of Incorporation, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in such person's official capacity and
as to action in any other capacity while holding such office, and shall continue
as to a person who has ceased to be an officer or director of the Corporation or
a subsidiary thereof or an officer, director, partner, member, employee, trustee
or agent of another corporation, partnership, joint venture, trust or other
enterprise, including any employee benefit plan, and shall inure to the benefit
of the heirs, executors and administrators of such person.

      (l) This Article Ninth may be hereafter amended or repealed; provided,
however, that no amendment or repeal shall reduce, terminate, or otherwise
adversely affect the right of a person entitled to obtain indemnification
hereunder with respect to acts or omissions of such person occurring prior to
the effective date of such amendment or repeal.

      IN WITNESS WHEREOF, this Restated Certificate of Incorporation has been

2.    Employment Terms and Duties

      2.1 Employment. The Company hereby employs the Employee, and the Employee
hereby accepts employment by the Company, upon the terms and conditions set
forth in this Agreement.

      2.2 Term. Subject to the provisions of Section 6, the term of this
Agreement shall be three (3) years, commencing on February 10, 1998. Thereafter,
this Agreement shall be renewed automatically from year to year unless either
party shall have given written notice of termination to the other party at least
ninety (90) days prior to the end of the current term of this Agreement.

      2.3 Duties. The Employee will have such duties as are assigned or
delegated to the Employee by the Board of Directors and will serve as the
President of the Company. The Employee will devote substantially all his
business time and attention to the business of the Company, will act in good
faith to promote the success of the Company's business, and will cooperate fully
with the Board of Directors in the advancement of the best interests of the
Company. Nothing in this Section 2.3, however, will prevent the Employee from
engaging in additional activities in connection


                                       3
<PAGE>

with personal investments and community affairs that are not inconsistent with
the Employee's duties under this Agreement (which community affairs shall be
disclosed to and approved by the Chairman of the Board). If the Employee serves
as a director of the Company or as a director or officer of any of its
Affiliates, the Employee will fulfill his duties as such director or officer
without additional compensation.

3.    Compensation

      3.1 Basic Compensation.

            (a) Salary. The Employee will be paid a minimum base annual salary
      of $250,000 (the "Salary"), which will be payable in equal periodic
      installments according to the Company's customary payroll practices, but
      no less frequently than monthly. The Salary may be increased by the
      Compensation Committee or Board of Directors of the Company during the
      term of this Agreement, and when increased, such higher amount shall then
      be the minimum base annual salary under this Agreement. The Salary shall
      not be reduced below the highest minimum base annual salary fixed from
      time to time by the Compensation Committee or Board of Directors of the
      Company without the Employee's written consent. When increased or
      decreased in accordance with the terms of this Agreement, the new minimum
      base annual salary shall be deemed the Employee's "Salary" for all
      purposes of this Agreement.

            (b) Benefits. The Employee will, during the Employment Period, be
      permitted to participate in such pension, profit sharing, bonus, life
      insurance, disability insurance, hospitalization, major medical, and other
      employee benefit plans of the Company that may be in effect from time to
      time, to the extent the Employee is eligible under the terms of such plans
      (collectively, the "Benefits").

      3.2 Incentive Compensation. The Employee shall be entitled to participate
in an incentive bonus program established by the Board of Directors or the
Compensation Committee of the Board of Directors to measure and reward
management for the financial performance of the Company. The Employee's initial
annual targeted incentive compensation shall be $150,000; provided, however,
that the payment of any incentive compensation shall be at the discretion of the
Compensation Committee of the Board of Directors, which may consider any factors
it deems relevant, including the assessment of the performance of the Employee
and the Company during the relevant time period.

4.    Facilities and Expenses

The Company will furnish the Employee office space, equipment, supplies, and
such other facilities and personnel as the Company deems necessary or
appropriate for the performance of the Employee's duties under this Agreement.
The Company will pay the Employee's dues in such professional societies and
organizations as the Chairman of the Board deems appropriate, and will pay on
behalf of the Employee (or reimburse the Employee for) reasonable expenses
incurred by the


                                       4
<PAGE>

Employee at the request of, or on behalf of, the Company in the performance of
the Employee's duties pursuant to this Agreement, and in accordance with the
Company's employment policies, including reasonable expenses incurred by the
Employee in attending conventions, seminars, and other business meetings, in
appropriate business entertainment activities, and for promotional expenses.

5.    Vacations and Holidays

The Employee will be entitled to paid vacation in accordance with the vacation
policies of the Company in effect for its employee officers from time to time.
Vacation must be taken by the Employee at such time or times as approved by the
Chairman of the Board. The Employee will also be entitled to the paid holidays
set forth in the Company's policies.

6.    Termination

      6.1 Events of Termination. The Employment Period, the Employee's Salary,
Benefits, and Incentive Compensation, and any and all other rights of the
Employee under this Agreement will terminate (except as otherwise provided in
this Section 6):

            (a) upon the death of the Employee;

            (b) upon the Disability of the Employee (as defined in Section 6.2)
      immediately upon notice from either party to the other;

            (c) for Cause (as defined in Section 6.3), immediately upon notice
      from the Company to the Employee, or at such later time as such notice may
      specify;

            (d) for Good Reason (as defined in Section 6.4) upon not less than
      thirty days' prior notice from the Employee to the Company; or

            (e) without Cause upon not less than thirty days' notice from the
      Company to the Employee.

      6.2 Definition of "Disability." For purposes of Section 6.1, the Employee
will be deemed to have a "Disability" if, for physical or mental reasons, the
Employee is unable to perform the Employee's duties under this Agreement for 120
consecutive days, or 180 days during any twelve month period, as determined in
accordance with this Section 6.2. The Disability of the Employee will be
determined by a medical doctor selected by written agreement of the Company and
the Employee upon the request of either party by notice to the other. If the
Company and the Employee cannot agree on the selection of a medical doctor, each
of them will select a medical doctor and the two medical doctors will select a
third medical doctor who will determine whether the Employee has a Disability.
The determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Employee must submit to a reasonable number of
examinations by the medical doctor making the determination of Disability under
this Section 6.2, and to other specialists designated by such medical doctor,
and the Employee hereby authorizes the


                                       5
<PAGE>

disclosure and release to the Company of such determination and all supporting
medical records. If the Employee is not legally competent, the Employee's legal
guardian or duly authorized attorney-in-fact will act in the Employee's stead
under this Section 6.2 for the purposes of submitting the Employee to the
examinations, and providing the authorization of disclosure, required under this
Section 6.2.

      6.3 Definition of "Cause." For purposes of Section 6.1, the term "Cause"
means: (a) the Employee's breach of a material obligation under this Agreement;
(b) the Employee's failure to adhere in any material respect to any written
Company policy if such policy is material to the effective performance by the
Employee of his duties under this Agreement, and if the Employee has been given
a reasonable opportunity to cure his failure to comply within the thirty-day
period preceding termination of this Agreement, provided that if the Employee
cures his failure to comply with such a policy and then fails again to comply
with the same policy, no further opportunity to cure that failure shall be
required; (c) the appropriation (or attempted appropriation) of a material
business opportunity of the Company, including attempting to secure or securing
any personal profit in connection with any transaction entered into on behalf of
the Company (other than through stock options, bonuses and other incentives
provided by the Company to the Employee); (d) the misappropriation (or attempted
misappropriation) of any of the Company's funds or property; or (e) the
conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, or a crime involving moral turpitude, dishonesty, or
fraud.

      6.4 Definition of "Good Reason." For purposes of Section 6.1, the term
"Good Reason" shall mean (a) a substantial reduction in the Employee's duties or
responsibilities, (b) any reduction in Employee's Salary, or (c) relocation of
the Employee's primary workplace to a location that is greater than 35 miles
from the Employee's current workplace, in each case which is not cured within 30
days following the Company's receipt of written notice from the Employee
describing the event constituting Good Reason.

      6.5 Termination Pay. Effective upon the expiration or termination of this
Agreement, the Company will be obligated to pay the Employee (or, in the event
of his death, his designated beneficiary as defined below) only such
compensation as is provided in this Section 6.5. For purposes of this Section
6.5 the Employee's designated beneficiary will be such individual beneficiary or
trust, located at such address, as the Employee may designate by notice to the
Company from time to time or, if the Employee fails to give notice to the
Company of such a beneficiary, the Employee's estate. Notwithstanding the
preceding sentence, the Company will have no duty, in any circumstances, to
attempt to open an estate on behalf of the Employee, to determine whether any
beneficiary designated by the Employee is alive or to ascertain the address of
any such beneficiary, to determine the existence of any trust, to determine
whether any Person purporting to act as the Employee's personal representative
(or the trustee of a trust established by the Employee) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee.

      (a) Termination by the Employee for Good Reason or by the Company without
      Cause. If the Employee terminates this Agreement for Good Reason, or if
      the Company terminates


                                       6
<PAGE>

      this Agreement other than for Cause (but not because of the Disability or
      death of the Employee), or if the Company notifies the Employee in
      accordance with Section 2.2 that this Agreement will not be renewed as of
      an applicable expiration date, the Company will pay the Employee (i) the
      Employee's Salary for the remainder, if any, of the calendar month in
      which such termination is effective and for twenty-four consecutive
      calendar months thereafter, (ii) the amount of the Employee's targeted
      incentive compensation for the year during which the termination is
      effective (prorated for the period from the beginning of the year until
      the effective date of termination), and (iii) the sum of two times the
      amount of the Employee's targeted incentive compensation for the year in
      which the termination was effective (such amount to be determined as if
      the Employee had been employed for the entire year and not prorated as
      described in clause (ii) above), payable in equal monthly installments
      over the Post-Employment Period. Notwithstanding the preceding sentence,
      if the Employee obtains other employment prior to the end of the
      twenty-four months following the month in which the termination or
      expiration is effective, he must promptly give notice thereof to the
      Company, and the payments under this Agreement for any period after the
      Employee obtains other employment will be reduced by the amount of the
      cash compensation received and to be received by the Employee from the
      Employee's other employment for services performed during such period.

            (b) Termination by the Company for Cause. If the Company terminates
      this Agreement for Cause, the Employee will be entitled to receive his
      Salary only through the date such termination is effective.

            (c) Termination upon Disability. If this Agreement is terminated by
      either party as a result of the Employee's Disability, as determined under
      Section 6.2, the Company will pay the Employee his Salary through the
      remainder of the calendar month during which such termination is effective
      and for the lesser of (i) six consecutive months thereafter, or (ii) the
      period until disability insurance benefits commence under any disability
      insurance coverage furnished by the Company to the Employee.

            (d) Termination upon Death. If this Agreement is terminated because
      of the Employee's death, the Employee will be entitled to receive his
      Salary through the end of the calendar month in which his death occurs.

            (e) Benefits. Except as otherwise required by law, the Employee's
      accrual of, or participation in plans providing for, the Benefits will
      cease at the effective date of the termination of this Agreement, and the
      Employee will be entitled to accrued Benefits pursuant to such plans only
      as provided in such plans.

7.    Non-Disclosure Covenant; Employee Inventions

      7.1 Acknowledgments by the Employee. The Employee acknowledges that (a)
during the Employment Period and as a part of his employment, the Employee will
be afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an


                                       7
<PAGE>

adverse effect on the Company and its business; (c) because the Employee
possesses substantial technical expertise and skill with respect to the
Company's business, the Company desires to obtain exclusive ownership of each
Employee Invention, and the Company will be at a substantial competitive
disadvantage if it fails to acquire exclusive ownership of each Employee
Invention; and (d) the provisions of this Section 7 are reasonable and necessary
to prevent the improper use or disclosure of Confidential Information and to
provide the Company with exclusive ownership of all Employee Inventions.

      7.2 Agreements of the Employee. In consideration of the compensation and
benefits to be paid or provided to the Employee by the Company under this
Agreement, the Employee covenants as follows:

            (a)  Confidentiality.

                  (i) During and following the Employment Period, the Employee
            will hold in confidence the Confidential Information and will not
            disclose it to any Person except with the specific prior written
            consent of the Company or except as otherwise expressly permitted by
            the terms of this Agreement.

                  (ii) Any trade secrets of the Company will be entitled to all
            of the protections and benefits under the Missouri Uniform Trade
            Secrets Act and any other applicable law. If any information that
            the Company deems to be a trade secret is found by a court of
            competent jurisdiction not to be a trade secret for purposes of this
            Agreement, such information will, nevertheless, be considered
            Confidential Information for purposes of this Agreement. The
            Employee hereby waives any requirement that the Company submit proof
            of the economic value of any trade secret or post a bond or other
            security.

                  (iii) None of the foregoing obligations and restrictions
            applies to any part of the Confidential Information that the
            Employee demonstrates was or became generally available to the
            public other than as a result of a disclosure by the Employee or by
            any other Person bound by a confidentiality obligation to the
            Company in respect of such Confidential Information.

                  (iv) The Employee will not remove from the Company's premises
            (except to the extent such removal is for purposes of the
            performance of the Employee's duties at home or while traveling, or
            except as otherwise specifically authorized by the Company) any
            Company document, record, notebook, plan, model, component, device,
            or computer software or code, whether embodied in a disk or in any
            other form (collectively, the "Proprietary Items"). The Employee
            recognizes that, as between the Company and the Employee, all of the
            Proprietary Items, whether or not developed by the Employee, are the
            exclusive property of the Company. Upon termination of this
            Agreement by either party, or upon the request of the Company during
            the Employment Period, the Employee will return to the Company all
            of the Proprietary Items in the Employee's possession or subject to
            the Employee's control,


                                       8
<PAGE>

            and the Employee shall not retain any copies, abstracts, sketches,
            or other physical embodiment of any of the Proprietary Items.

            (b) Employee Inventions. Each Employee Invention will belong
      exclusively to the Company. The Employee acknowledges that all Employee
      Inventions are works made for hire and are the property of the Company,
      including any copyrights, patents, or other intellectual property rights
      pertaining thereto. If it is determined that any such works are not works
      made for hire, the Employee hereby assigns to the Company all of the
      Employee's right, title, and interest, including all rights of copyright,
      patent, and other intellectual property rights, to or in such Employee
      Inventions. The Employee will promptly:

                  (i) disclose to the Company in writing any Employee Invention;

                  (ii) assign to the Company or to a party designated by the
            Company, at the Company's request and without additional
            compensation, all of the Employee's right to the Employee Invention
            for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Company such applications,
            assignments, and other documents as the Company may request in order
            to apply for and obtain patents or other registrations with respect
            to any Employee Invention in the United States and any foreign
            jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
            obligations; and

                  (v) give testimony and render any other assistance in support
            of the Company's rights to any Employee Invention.

      Notwithstanding anything to the contrary herein, provisions otherwise
      requiring the Employee to assign to the Company any invention conceived by
      the Employee shall not apply to an invention for which no equipment,
      supplies, facilities or trade secret information of the Company was used
      and which was developed entirely on the Employee's own time, unless the
      invention relates to the business of the Company or to the Company's
      actual or demonstrably anticipated research or development, or the
      invention results from any work performed by the Employee for the Company.

      7.3 Disputes or Controversies. The Employee recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Employee, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information

the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary, and intellectual character; (b) the Company
competes with other businesses that are or could be located in any part of the
Territory; and (c) the provisions of this Section 8 are reasonable and necessary
to protect the Company's business.

      8.2 Covenants of the Employee. In consideration of the acknowledgments by
the Employee, and in consideration of the compensation and benefits to be paid
or provided to the Employee by the Company, the Employee covenants that he will
not, directly or indirectly:

            (a) during the Employment Period, except in the course of his
      employment hereunder, and during the Post-Employment Period, engage or
      invest in, own, manage, operate, finance, control, or participate in the
      ownership, management, operation, financing, or control of, be employed
      by, associated with, or in any manner connected with, lend the Employee's
      name or any similar name to, lend Employee's credit to or render services
      or advice to, any Competitive Business within the Territory; provided,
      however, that the Employee may purchase or otherwise acquire up to (but
      not more than) one percent of any class of securities of any enterprise
      (but without otherwise participating in the activities of such enterprise)
      if such securities are listed on any national or regional securities
      exchange or have been registered under Section 12(g) of the Securities
      Exchange Act of 1934;

            (b) whether for the Employee's own account or for the account of any
      other Person, at any time during the Employment Period and the
      Post-Employment Period, solicit business of the same or similar type being
      carried on by the Company, from any Person known by the Employee to be a
      customer of the Company, whether or not the Employee had personal contact
      with such Person during and by reason of the Employee's employment with
      the Company;

            (c) whether for the Employee's own account or the account of any
      other Person at any time during the Employment Period and the
      Post-Employment Period, solicit, employ, or otherwise engage as an
      employee, independent contractor, or otherwise, any person who is or was
      an employee of the Company at any time during the Employment Period or in
      any manner induce or attempt to induce any employee of the Company to
      terminate his or her employment with the Company; or at any time during
      the Employment Period and the Post-Employment Period, interfere with the
      Company's relationship with any person, including any person who at any
      time during the Employment Period was an employee, contractor, supplier,
      or customer of the Company;

            (d) at any time during the Employment Period and the Post-Employment
      Period, disparage the Company or any of its shareholders, directors,
      officers, employees, or agents.

      8.3 Divisible Covenants. If any covenant in Section 8.2 is held to be
unreasonable, arbitrary, or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as


                                       10
<PAGE>

a court of competent jurisdiction may determine to be reasonable, not arbitrary,
and not against public policy, will be effective, binding, and enforceable
against the Employee.

      8.4 Extension of Covenants. The period of time applicable to any covenant
in Section 8.2 will be extended by the duration of any violation by the Employee
of such covenant.

      8.5 Notices. The Employee will, while the covenants under Section 8.2 are
in effect, give notice to the Company, within ten days after accepting any other
employment, of the identity of the Employee's new employer. The Company may
notify such new employer that the Employee is bound by this Agreement and, at
the Company's election, furnish such new employer with a copy of this Agreement
or relevant portions thereof.

9.    General Provisions

      9.1 Injunctive Relief and Additional Remedy. The Employee acknowledges
that the injury that would be suffered by the Company as a result of a breach of
the provisions of this Agreement (including any provision of Sections 7 and 8)
would be irreparable and that an award of monetary damages to the Company for
such a breach would be an inadequate remedy. Consequently, the Company will have
the right, in addition to any other rights it may have, to obtain injunctive
relief to restrain any breach or threatened breach or otherwise to specifically
enforce any provision of this Agreement, and the Company will not be obligated
to post bond or other security in seeking such relief. Without limiting the
Company's rights under this Section 9 or any other remedies of the Company, if
the Employee breaches any of the provisions of Section 7 or 8, the Company will
have the right to cease making any payments otherwise due to the Employee under
this Agreement.

      9.2 Covenants of Sections 7 and 8 are Essential and Independent Covenants.
The covenants by the Employee in Sections 7 and 8 are essential elements of this
Agreement, and without the Employee's agreement to comply with such covenants,
the Company would not have entered into this Agreement or employed the Employee.
The Company and the Employee have independently consulted their respective
counsel and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Company. The Employee's covenants in Sections 7 and 8 are
independent covenants and the existence of any claim by the Employee against the
Company, under this Agreement or otherwise, will not excuse the Employee's
breach of any covenant in Section 7 or 8. If the Employee's employment hereunder
expires or is terminated, this Agreement will continue in full force and effect
as is necessary or appropriate to enforce the covenants and agreements of the
Employee in Sections 7 and 8.

      9.3 Representations and Warranties by the Employee. The Employee
represents and warrants to the Company that the execution and delivery by the
Employee of this Agreement do not, and the performance by the Employee of the
Employee's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Employee; or (b) conflict with, result in the breach of any provisions of or the
termination of, or constitute a


                                       11
<PAGE>

default under, any agreement to which the Employee is a party or by which the
Employee is or may be bound.

      9.4 Obligations Contingent on Performance. The obligations of the Company
hereunder, including its obligation to pay the compensation provided for herein,
are contingent upon the Employee's performance of the Employee's obligations
hereunder.

      9.5 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

      9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement shall
inure to the benefit of, and shall be binding upon, the parties hereto and their
respective successors, assigns, heirs, and legal representatives, including any
entity with which the Company may merge or consolidate or to which all or
substantially all of its assets may be transferred. The duties and covenants of
the Employee under this Agreement, being personal, may not be delegated.

      9.7 Notices. All notices and other communications under this Agreement
must be in writing and will be deemed to have been duly given when (a) delivered
by hand (with written confirmation of receipt), (b) sent by facsimile (with
written confirmation of receipt), provided that a copy is mailed by registered
mail, return receipt requested, or (c) when received by the addressee, if sent
by a nationally recognized overnight delivery service (receipt requested), in
the case of the Company to the attention of the Chairman of the Board with
respect to David E. Scott's Agreement at the Company's principal business office
and in the case of the Employee to the address or facsimile number set forth

2.    Employment Terms and Duties

      2.1 Employment. The Company hereby employs the Employee, and the Employee
hereby accepts employment by the Company, upon the terms and conditions set
forth in this Agreement.

      2.2 Term. Subject to the provisions of Section 6, the term of this

                                       3

      no less frequently than monthly. The Salary may be increased by the
      Compensation Committee or Board of Directors of the Company during the
      term of this Agreement, and when increased, such higher amount shall then
      be the minimum base annual salary under this Agreement. The Salary shall
      not be reduced below the highest minimum base annual salary fixed from
      time to time by the Compensation Committee or Board of Directors of the
      Company without the Employee's written consent. When increased or
      decreased in accordance with the terms of this Agreement, the new minimum
      base annual salary shall be deemed the Employee's "Salary" for all
      purposes of this Agreement.

            (b) Benefits. The Employee will, during the Employment Period, be
      permitted to participate in such pension, profit sharing, bonus, life
      insurance, disability insurance, hospitalization, major medical, and other
      employee benefit plans of the Company that may be in effect from time to
      time, to the extent the Employee is eligible under the terms of such plans
      (collectively, the "Benefits").

      3.2 Incentive Compensation. The Employee shall be entitled to participate
in an incentive bonus program established by the Board of Directors or the
Compensation Committee of the Board of Directors to measure and reward
management for the financial performance of the Company. The Employee's initial
annual targeted incentive compensation shall be $50,000; provided, however, that
the payment of any incentive compensation shall be at the discretion of the
Compensation Committee of the Board of Directors, which may consider any factors
it deems relevant, including the assessment of the performance of the Employee
and the Company during the relevant time period.

4.    Facilities and Expenses

<PAGE>

the request of, or on behalf of, the Company in the performance of the

appropriate business entertainment activities, and for promotional expenses.

5.    Vacations and Holidays

policies of the Company in effect for its employee officers from time to time.

President. The Employee will also be entitled to the paid holidays set forth in
the Company's policies.

6.    Termination

      6.1 Events of Termination. The Employment Period, the Employee's Salary,

this Section 6):

            (a) upon the death of the Employee;

            (b) upon the Disability of the Employee (as defined in Section 6.2)
      immediately upon notice from either party to the other;

            (c) for Cause (as defined in Section 6.3), immediately upon notice
      from the Company to the Employee, or at such later time as such notice may
      specify;

            (d) for Good Reason (as defined in Section 6.4) upon not less than
      thirty days' prior notice from the Employee to the Company; or

            (e) without Cause upon not less than thirty days' notice from the
      Company to the Employee.

      6.2 Definition of "Disability." For purposes of Section 6.1, the Employee
will be deemed to have a "Disability" if, for physical or mental reasons, the
Employee is unable to perform the Employee's duties under this Agreement for 120
consecutive days, or 180 days during any twelve month period, as determined in
accordance with this Section 6.2. The Disability of the Employee will be
determined by a medical doctor selected by written agreement of the Company and
the Employee upon the request of either party by notice to the other. If the
Company and the Employee cannot agree on the selection of a medical doctor, each
of them will select a medical doctor and the two medical doctors will select a
third medical doctor who will determine whether the Employee has a Disability.
The determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Employee must submit to a reasonable number of
examinations by the medical doctor making the determination of Disability under
this Section 6.2, and to other specialists designated by such medical doctor,
and the Employee hereby authorizes the disclosure and release to the Company of
such determination and all supporting medical records. If


                                       5
<PAGE>

the Employee is not legally competent, the Employee's legal guardian or duly
authorized attorney-in-fact will act in the Employee's stead under this Section
6.2 for the purposes of submitting the Employee to the examinations, and
providing the authorization of disclosure, required under this Section 6.2.

      6.3 Definition of "Cause." For purposes of Section 6.1, the term "Cause"
means: (a) the Employee's breach of a material obligation under this Agreement;
(b) the Employee's failure to adhere in any material respect to any written
Company policy if such policy is material to the effective performance by the
Employee of his duties under this Agreement, and if the Employee has been given
a reasonable opportunity to cure his failure to comply within the thirty-day
period preceding termination of this Agreement, provided that if the Employee
cures his failure to comply with such a policy and then fails again to comply
with the same policy, no further opportunity to cure that failure shall be
required; (c) the appropriation (or attempted appropriation) of a material
business opportunity of the Company, including attempting to secure or securing
any personal profit in connection with any transaction entered into on behalf of
the Company (other than through stock options, bonuses and other incentives
provided by the Company to the Employee); (d) the misappropriation (or attempted
misappropriation) of any of the Company's funds or property; or (e) the
conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, or a crime involving moral turpitude, dishonesty, or
fraud.

      6.4 Definition of "Good Reason." For purposes of Section 6.1, the term
"Good Reason" shall mean (a) a substantial reduction in the Employee's duties or
responsibilities, (b) any reduction in Employee's Salary, or (c) relocation of
the Employee's primary workplace to a location that is greater than 35 miles
from the Employee's current workplace, in each case which is not cured within 30
days following the Company's receipt of written notice from the Employee
describing the event constituting Good Reason.

      6.5 Termination Pay. Effective upon the expiration or termination of this
Agreement, the Company will be obligated to pay the Employee (or, in the event
of his death, his designated beneficiary as defined below) only such
compensation as is provided in this Section 6.5. For purposes of this Section
6.5 the Employee's designated beneficiary will be such individual beneficiary or
trust, located at such address, as the Employee may designate by notice to the
Company from time to time or, if the Employee fails to give notice to the
Company of such a beneficiary, the Employee's estate. Notwithstanding the
preceding sentence, the Company will have no duty, in any circumstances, to
attempt to open an estate on behalf of the Employee, to determine whether any
beneficiary designated by the Employee is alive or to ascertain the address of
any such beneficiary, to determine the existence of any trust, to determine
whether any Person purporting to act as the Employee's personal representative
(or the trustee of a trust established by the Employee) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee.

      (a) Termination by the Employee for Good Reason or by the Company without
      Cause. If the Employee terminates this Agreement for Good Reason, or if
      the Company terminates this Agreement other than for Cause (but not
      because of the Disability or death of the Employee), or if the Company
      notifies the Employee in accordance with Section 2.2 that


                                       6
<PAGE>

      this Agreement will not be renewed as of an applicable expiration date,
      the Company will pay the Employee (i) the Employee's Salary for the
      remainder, if any, of the calendar month in which such termination is
      effective and for twelve consecutive calendar months thereafter, (ii) the
      amount of the Employee's targeted incentive compensation for the year
      during which the termination is effective (prorated for the period from
      the beginning of the year until the effective date of termination), and
      (iii) with respect to the Post-Employment Period, an additional amount
      equal to the full amount of the Employee's targeted incentive compensation
      for the year in which the termination was effective (such amount to be


                                       7
<PAGE>

      determined as if the Employee had been employed for the entire year and
      not prorated as described in clause (ii) above), payable in equal monthly
      installments over the Post-Employment Period. Notwithstanding the
      preceding sentence, if the Employee obtains other employment prior to the
      end of the Post-Employment Period or any extension thereof, he must
      promptly give notice thereof to the Company, and the payments under this
      Agreement for any period after the Employee obtains other employment will
      be reduced by the amount of the cash compensation received and to be
      received by the Employee from the Employee's other employment for services
      performed during such period.

            (b) Termination by the Company for Cause. If the Company terminates
      this Agreement for Cause, the Employee will be entitled to receive his
      Salary only through the date such termination is effective.

            (c) Termination upon Disability. If this Agreement is terminated by
      either party as a result of the Employee's Disability, as determined under
      Section 6.2, the Company will pay the Employee his Salary through the
      remainder of the calendar month during which such termination is effective
      and for the lesser of (i) six consecutive months thereafter, or (ii) the
      period until disability insurance benefits commence under any disability
      insurance coverage furnished by the Company to the Employee.

            (d) Termination upon Death. If this Agreement is terminated because
      of the Employee's death, the Employee will be entitled to receive his
      Salary through the end of the calendar month in which his death occurs.

            (e) Benefits. Except as otherwise required by law, the Employee's
      accrual of, or participation in plans providing for, the Benefits will
      cease at the effective date of the termination of this Agreement, and the
      Employee will be entitled to accrued Benefits pursuant to such plans only
      as provided in such plans.

7.    Non-Disclosure Covenant; Employee Inventions

      7.1 Acknowledgments by the Employee. The Employee acknowledges that (a)
during the Employment Period and as a part of his employment, the Employee will
be afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Company and its
business; (c) because the Employee possesses substantial technical expertise and
skill with respect to the Company's business, the Company desires to obtain
exclusive ownership of each Employee Invention, and the Company will be at a
substantial competitive disadvantage if it fails to acquire exclusive ownership
of each Employee Invention; and (d) the provisions of this Section 7 are
reasonable and necessary to prevent the improper use or disclosure of
Confidential Information and to provide the Company with exclusive ownership of
all Employee Inventions.


                                       8

      7.2 Agreements of the Employee. In consideration of the compensation and
benefits to be paid or provided to the Employee by the Company under this
Agreement, the Employee covenants as follows:

            (a)  Confidentiality.

                  (i) During and following the Employment Period, the Employee
            will hold in confidence the Confidential Information and will not
            disclose it to any Person except with the specific prior written
            consent of the Company or except as otherwise expressly permitted by
            the terms of this Agreement.

                  (ii) Any trade secrets of the Company will be entitled to all
            of the protections and benefits under the Missouri Uniform Trade
            Secrets Act and any other applicable law. If any information that
            the Company deems to be a trade secret is found by a court of
            competent jurisdiction not to be a trade secret for purposes of this
            Agreement, such information will, nevertheless, be considered
            Confidential Information for purposes of this Agreement. The
            Employee hereby waives any requirement that the Company submit proof
            of the economic value of any trade secret or post a bond or other
            security.

                  (iii) None of the foregoing obligations and restrictions
            applies to any part of the Confidential Information that the
            Employee demonstrates was or became generally available to the
            public other than as a result of a disclosure by the Employee or by
            any other Person bound by a confidentiality obligation to the
            Company in respect of such Confidential Information.

                  (iv) The Employee will not remove from the Company's premises
            (except to the extent such removal is for purposes of the
            performance of the Employee's duties at home or while traveling, or
            except as otherwise specifically authorized by the Company) any
            Company document, record, notebook, plan, model, component, device,
            or computer software or code, whether embodied in a disk or in any
            other form (collectively, the "Proprietary Items"). The Employee
            recognizes that, as between the Company and the Employee, all of the
            Proprietary Items, whether or not developed by the Employee, are the
            exclusive property of the Company. Upon termination of this
            Agreement by either party, or upon the request of the Company during
            the Employment Period, the Employee will return to the Company all
            of the Proprietary Items in the Employee's possession or subject to
            the Employee's control, and the Employee shall not retain any
            copies, abstracts, sketches, or other physical embodiment of any of
            the Proprietary Items.

            (b) Employee Inventions. Each Employee Invention will belong
      exclusively to the Company. The Employee acknowledges that all Employee
      Inventions are works made for hire and are the property of the Company,
      including any copyrights, patents, or other intellectual property rights
      pertaining thereto. If it is determined that any such works are not


                                       9
<PAGE>

      works made for hire, the Employee hereby assigns to the Company all of the
      Employee's right, title, and interest, including all rights of copyright,
      patent, and other intellectual property rights, to or in such Employee
      Inventions. The Employee will promptly:

                  (i) disclose to the Company in writing any Employee Invention;

                  (ii) assign to the Company or to a party designated by the
            Company, at the Company's request and without additional
            compensation, all of the Employee's right to the Employee Invention
            for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Company such applications,
            assignments, and other documents as the Company may request in order
            to apply for and obtain patents or other registrations with respect
            to any Employee Invention in the United States and any foreign
            jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
            obligations; and

                  (v) give testimony and render any other assistance in support
            of the Company's rights to any Employee Invention.

      Notwithstanding anything to the contrary herein, provisions otherwise
      requiring the Employee to assign to the Company any invention conceived by
      the Employee shall not apply to an invention for which no equipment,
      supplies, facilities or trade secret information of the Company was used
      and which was developed entirely on the Employee's own time, unless the
      invention relates to the business of the Company or to the Company's
      actual or demonstrably anticipated research or development, or the
      invention results from any work performed by the Employee for the Company.

      7.3 Disputes or Controversies. The Employee recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Employee, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

8.    Non-Competition and Non-Interference

      8.1 Acknowledgments by the Employee. The Employee acknowledges that: (a)
the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary, and intellectual character; (b) the Company
competes with other businesses that are or could be located in any part of the
Territory; and (c) the provisions of this Section 8 are reasonable and necessary
to protect the Company's business.


                                       10
<PAGE>

      8.2 Covenants of the Employee. In consideration of the acknowledgments by
the Employee, and in consideration of the compensation and benefits to be paid
or provided to the Employee by the Company, the Employee covenants that he will
not, directly or indirectly:

            (a) during the Employment Period, except in the course of his
      employment hereunder, and during the Post-Employment Period, engage or
      invest in, own, manage, operate, finance, control, or participate in the
      ownership, management, operation, financing, or control of, be employed
      by, associated with, or in any manner connected with, lend the Employee's
      name or any similar name to, lend Employee's credit to or render services
      or advice to, any Competitive Business within the Territory; provided,
      however, that (i) the Employee may purchase or otherwise acquire up to
      (but not more than) one percent of any class of securities of any
      enterprise (but without otherwise participating in the activities of such
      enterprise) if such securities are listed on any national or regional
      securities exchange or have been registered under Section 12(g) of the
      Securities Exchange Act of 1934, and (ii) no restriction in this Agreement
      shall apply to the extent that it would violate or cause the Employee to
      violate any provision of the rules of professional conduct applicable to
      attorneys of any state where the Employee is licensed to practice law;

            (b) whether for the Employee's own account or for the account of any
      other Person, at any time during the Employment Period and the
      Post-Employment Period, solicit business of the same or similar type being
      carried on by the Company, from any Person known by the Employee to be a
      customer of the Company, whether or not the Employee had personal contact
      with such Person during and by reason of the Employee's employment with
      the Company;

            (c) whether for the Employee's own account or the account of any
      other Person at any time during the Employment Period and the
      Post-Employment Period, solicit, employ, or otherwise engage as an
      employee, independent contractor, or otherwise, any person who is or was
      an employee of the Company at any time during the Employment Period or in
      any manner induce or attempt to induce any employee of the Company to
      terminate his or her employment with the Company; or at any time during
      the Employment Period and the Post-Employment Period, interfere with the
      Company's relationship with any person, including any person who at any
      time during the Employment Period was an employee, contractor, supplier,
      or customer of the Company;

            (d) at any time during the Employment Period and the Post-Employment
      Period, disparage the Company or any of its shareholders, directors,
      officers, employees, or agents.

      8.3 Divisible Covenants. If any covenant in Section 8.2 is held to be
unreasonable, arbitrary, or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as a court of
competent jurisdiction may determine to be reasonable, not arbitrary, and not
against public policy, will be effective, binding, and enforceable against the
Employee.


                                       11
<PAGE>

      8.4 Extension of Covenants. The period of time applicable to any covenant
in Section 8.2 will be extended by the duration of any violation by the Employee
of such covenant. In addition, the period of time applicable to the covenants in
Section 8.2 may be extended, at the option of the Company, for a period of one
year after the expiration of the Post-Employment Period, provided that all of
the following conditions have been satisfied: (a) the Company has, within sixty
days of the effective date of termination of Employee's employment, provided
notice to the Employee of the Company's election to extend the period applicable
to the covenants in Section 8.2 for an additional year, (b) the Company has paid
all termination payments it is obligated to pay Employee relating to the
Employment Period and the Post-Employment Period, and (c) for such additional
year after the Post-Employment Period, the Company pays the Employee the sum of
the Employee's Salary plus an amount equal to the full amount of the Employee's
targeted incentive compensation for the year in which the termination was
effective, payable in equal monthly installments over that year.

      8.5 Notices. The Employee will, while the covenants under Section 8.2 are
in effect, give notice to the Company, within ten days after accepting any other
employment, of the identity of the Employee's new employer. The Company may
notify such new employer that the Employee is bound by this Agreement and, at
the Company's election, furnish such new employer with a copy of this Agreement
or relevant portions thereof.

9.    General Provisions

      9.1 Injunctive Relief and Additional Remedy. The Employee acknowledges
that the injury that would be suffered by the Company as a result of a breach of
the provisions of this Agreement (including any provision of Sections 7 and 8)
would be irreparable and that an award of monetary damages to the Company for
such a breach would be an inadequate remedy. Consequently, the Company will have
the right, in addition to any other rights it may have, to obtain injunctive
relief to restrain any breach or threatened breach or otherwise to specifically
enforce any provision of this Agreement, and the Company will not be obligated
to post bond or other security in seeking such relief. Without limiting the
Company's rights under this Section 9 or any other remedies of the Company, if
the Employee breaches any of the provisions of Section 7 or 8, the Company will
have the right to cease making any payments otherwise due to the Employee under
this Agreement.

      9.2 Covenants of Sections 7 and 8 are Essential and Independent Covenants.
The covenants by the Employee in Sections 7 and 8 are essential elements of this
Agreement, and without the Employee's agreement to comply with such covenants,
the Company would not have entered into this Agreement or employed the Employee.
The Company and the Employee have independently consulted their respective
counsel and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Company. The Employee's covenants in Sections 7 and 8 are
independent covenants and the existence of any claim by the Employee against the
Company, under this Agreement or otherwise, will not excuse the Employee's
breach of any covenant in Section 7 or 8. If the Employee's employment hereunder
expires or is terminated, this Agreement will continue in


                                       12
<PAGE>

full force and effect as is necessary or appropriate to enforce the covenants
and agreements of the Employee in Sections 7 and 8.

      9.3 Representations and Warranties by the Employee. The Employee
represents and warrants to the Company that the execution and delivery by the
Employee of this Agreement do not, and the performance by the Employee of the
Employee's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Employee; or (b) conflict with, result in the breach of any provisions of or the
termination of, or constitute a default under, any agreement to which the
Employee is a party or by which the Employee is or may be bound.

      9.4 Obligations Contingent on Performance. The obligations of the Company
hereunder, including its obligation to pay the compensation provided for herein,
are contingent upon the Employee's performance of the Employee's obligations
hereunder.

      9.5 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

      9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement shall
inure to the benefit of, and shall be binding upon, the parties hereto and their
respective successors, assigns, heirs, and legal representatives, including any
entity with which the Company may merge or consolidate or to which all or
substantially all of its assets may be transferred. The duties and covenants of
the Employee under this Agreement, being personal, may not be delegated.

      9.7 Notices. All notices and other communications under this Agreement
must be in writing and will be deemed to have been duly given when (a) delivered
by hand (with written confirmation of receipt), (b) sent by facsimile (with
written confirmation of receipt), provided that a copy is mailed by registered
mail, return receipt requested, or (c) when received by the addressee, if sent
by a nationally recognized overnight delivery service (receipt requested), in
the case of the Company to the attention of the President at the Company's
principal business office and in the case of the Employee to the address or
facsimile number set forth below (or to such other address or facsimile number
as the Employee may designate by notice to the Company):

2.    Employment Terms and Duties

      2.1 Employment. The Company hereby employs the Employee, and the Employee
hereby accepts employment by the Company, upon the terms and conditions set
forth in this Agreement.

      2.2 Term. Subject to the provisions of Section 6, the term of this
Agreement shall be one year, commencing on May 25, 1998. Thereafter, this
Agreement shall be renewed automatically from year to year unless either party
shall have given written notice of termination to the other party at least
ninety (90) days prior to the end of the current term of this Agreement.

      2.3 Duties. The Employee will have such duties as are assigned or
delegated to the Employee by the Board of Directors and President and will serve
as the Executive Vice President and Chief Operating Officer of the Company. The
Employee will devote substantially all his business time and attention to the
business of the Company, will act in good faith to promote the


                                       3
<PAGE>

success of the Company's business, and will cooperate fully with the Board of
Directors and President in the advancement of the best interests of the Company.
Nothing in this Section 2.3, however, will prevent the Employee from engaging in
additional activities in connection with personal investments and community
affairs that are not inconsistent with the Employee's duties under this
Agreement (which community affairs shall be disclosed to and approved by the
President). If the Employee serves as a director of the Company or as a director
or officer of any of its Affiliates, the Employee will fulfill his duties as
such director or officer without additional compensation.

3.    Compensation

      3.1   Basic Compensation.

            (a) Salary. The Employee will be paid a minimum base annual salary
      of $225,000 (the "Salary"), which will be payable in equal periodic
      installments according to the Company's customary payroll practices, but
      no less frequently than monthly. The Salary may be increased by the
      Compensation Committee or Board of Directors of the Company during the
      term of this Agreement, and when increased, such higher amount shall then
      be the minimum base annual salary under this Agreement. The Salary shall
      not be reduced below the highest minimum base annual salary fixed from
      time to time by the Compensation Committee or Board of Directors of the
      Company without the Employee's written consent. When increased or
      decreased in accordance with the terms of this Agreement, the new minimum
      base annual salary shall be deemed the Employee's "Salary" for all
      purposes of this Agreement.

            (b) Benefits. The Employee will, during the Employment Period, be
      permitted to participate in such pension, profit sharing, bonus, life
      insurance, disability insurance, hospitalization, major medical, and other
      employee benefit plans of the Company that may be in effect from time to
      time, to the extent the Employee is eligible under the terms of such plans
      (collectively, the "Benefits").

      3.2 Incentive Compensation. The Employee shall be entitled to participate
in an incentive bonus program established by the Board of Directors or the
Compensation Committee of the Board of Directors to measure and reward
management for the financial performance of the Company. The Employee's initial
annual targeted incentive compensation shall be $100,000; provided, however,
that the payment of any incentive compensation shall be at the discretion of the
Compensation Committee of the Board of Directors, which may consider any factors
it deems relevant, including the assessment of the performance of the Employee
and the Company during the relevant time period.

4.    Facilities and Expenses

The Company will furnish the Employee office space, equipment, supplies, and
such other facilities and personnel as the Company deems necessary or
appropriate for the performance of the Employee's duties under this Agreement.
The Company will pay the Employee's dues in such


                                       4
<PAGE>

professional societies and organizations as the President deems appropriate, and
will pay on behalf of the Employee (or reimburse the Employee for) reasonable
expenses incurred by the Employee at the request of, or on behalf of, the
Company in the performance of the Employee's duties pursuant to this Agreement,
and in accordance with the Company's employment policies, including reasonable
expenses incurred by the Employee in attending conventions, seminars, and other
business meetings, in appropriate business entertainment activities, and for
promotional expenses.

5.    Vacations and Holidays

The Employee will be entitled to paid vacation in accordance with the vacation
policies of the Company in effect for its employee officers from time to time.
Vacation must be taken by the Employee at such time or times as approved by the
President. The Employee will also be entitled to the paid holidays set forth in
the Company's policies.

6.    Termination

      6.1 Events of Termination. The Employment Period, the Employee's Salary,
Benefits, and Incentive Compensation, and any and all other rights of the
Employee under this Agreement will terminate (except as otherwise provided in
this Section 6):

            (a)  upon the death of the Employee;

            (b) upon the Disability of the Employee (as defined in Section 6.2)
      immediately upon notice from either party to the other;

            (c) for Cause (as defined in Section 6.3), immediately upon notice
      from the Company to the Employee, or at such later time as such notice may
      specify;

            (d) for Good Reason (as defined in Section 6.4) upon not less than
      thirty days' prior notice from the Employee to the Company; or

            (e) without Cause upon not less than thirty days' notice from the
      Company to the Employee.

      6.2 Definition of "Disability." For purposes of Section 6.1, the Employee
will be deemed to have a "Disability" if, for physical or mental reasons, the
Employee is unable to perform the Employee's duties under this Agreement for 120
consecutive days, or 180 days during any twelve month period, as determined in
accordance with this Section 6.2. The Disability of the Employee will be
determined by a medical doctor selected by written agreement of the Company and
the Employee upon the request of either party by notice to the other. If the
Company and the Employee cannot agree on the selection of a medical doctor, each
of them will select a medical doctor and the two medical doctors will select a
third medical doctor who will determine whether the Employee has a Disability.
The determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Employee must submit to a reasonable number of
examinations by the medical doctor making the determination of Disability under
this Section 6.2,


                                       5
<PAGE>

and to other specialists designated by such medical doctor, and the Employee
hereby authorizes the disclosure and release to the Company of such
determination and all supporting medical records. If the Employee is not legally
competent, the Employee's legal guardian or duly authorized attorney-in-fact
will act in the Employee's stead under this Section 6.2 for the purposes of
submitting the Employee to the examinations, and providing the authorization of
disclosure, required under this Section 6.2.

      6.3 Definition of "Cause." For purposes of Section 6.1, the term "Cause"
means: (a) the Employee's breach of a material obligation under this Agreement;
(b) the Employee's failure to adhere in any material respect to any written
Company policy if such policy is material to the effective performance by the
Employee of his duties under this Agreement, and if the Employee has been given
a reasonable opportunity to cure his failure to comply within the thirty-day
period preceding termination of this Agreement, provided that if the Employee
cures his failure to comply with such a policy and then fails again to comply
with the same policy, no further opportunity to cure that failure shall be
required; (c) the appropriation (or attempted appropriation) of a material
business opportunity of the Company, including attempting to secure or securing
any personal profit in connection with any transaction entered into on behalf of
the Company (other than through stock options, bonuses and other incentives
provided by the Company to the Employee); (d) the misappropriation (or attempted
misappropriation) of any of the Company's funds or property; or (e) the
conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, or a crime involving moral turpitude, dishonesty, or
fraud.

      6.4 Definition of "Good Reason." For purposes of Section 6.1, the term
"Good Reason" shall mean (a) a substantial reduction in the Employee's duties or
responsibilities, (b) any reduction in Employee's Salary, or (c) relocation of
the Employee's primary workplace to a location that is greater than 35 miles
from the Employee's current workplace, in each case which is not cured within 30
days following the Company's receipt of written notice from the Employee
describing the event constituting Good Reason.

      6.5 Termination Pay. Effective upon the expiration or termination of this
Agreement, the Company will be obligated to pay the Employee (or, in the event
of his death, his designated beneficiary as defined below) only such
compensation as is provided in this Section 6.5. For purposes of this Section
6.5 the Employee's designated beneficiary will be such individual beneficiary or
trust, located at such address, as the Employee may designate by notice to the
Company from time to time or, if the Employee fails to give notice to the
Company of such a beneficiary, the Employee's estate. Notwithstanding the
preceding sentence, the Company will have no duty, in any circumstances, to
attempt to open an estate on behalf of the Employee, to determine whether any
beneficiary designated by the Employee is alive or to ascertain the address of
any such beneficiary, to determine the existence of any trust, to determine
whether any Person purporting to act as the Employee's personal representative
(or the trustee of a trust established by the Employee) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee.

      (a) Termination by the Employee for Good Reason or by the Company without
      Cause. If


                                       6
<PAGE>

      the Employee terminates this Agreement for Good Reason, or if the Company
      terminates this Agreement other than for Cause (but not because of the
      Disability or death of the Employee), or if the Company notifies the
      Employee in accordance with Section 2.2 that this Agreement will not be
      renewed as of an applicable expiration date, the Company will pay the
      Employee (i) the Employee's Salary for the remainder, if any, of the
      calendar month in which such termination is effective and for twenty-four
      consecutive calendar months thereafter, (ii) the amount of the Employee's
      targeted incentive compensation for the year during which the termination
      is effective (prorated for the period from the beginning of the year until
      the effective date of termination), and (iii) the sum of two times the
      amount of the Employee's targeted incentive compensation for the year in
      which the termination was effective (such amount to be determined as if
      the Employee had been employed for the entire year and not prorated as
      described in clause (ii) above), payable in equal monthly installments
      over the Post-Employment Period. Notwithstanding the preceding sentence,
      if the Employee obtains other employment prior to the end of the
      twenty-four months following the month in which the termination or
      expiration is effective, he must promptly give notice thereof to the
      Company, and the payments under this Agreement for any period after the
      Employee obtains other employment will be reduced by the amount of the
      cash compensation received and to be received by the Employee from the
      Employee's other employment for services performed during such period.

            (b) Termination by the Company for Cause. If the Company terminates
      this Agreement for Cause, the Employee will be entitled to receive his
      Salary only through the date such termination is effective.

            (c) Termination upon Disability. If this Agreement is terminated by
      either party as a result of the Employee's Disability, as determined under
      Section 6.2, the Company will pay the Employee his Salary through the
      remainder of the calendar month during which such termination is effective
      and for the lesser of (i) six consecutive months thereafter, or (ii) the
      period until disability insurance benefits commence under any disability
      insurance coverage furnished by the Company to the Employee.

            (d) Termination upon Death. If this Agreement is terminated because
      of the Employee's death, the Employee will be entitled to receive his
      Salary through the end of the calendar month in which his death occurs.

            (e) Benefits. Except as otherwise required by law, the Employee's
      accrual of, or participation in plans providing for, the Benefits will
      cease at the effective date of the termination of this Agreement, and the
      Employee will be entitled to accrued Benefits pursuant to such plans only
      as provided in such plans.

7.    Non-Disclosure Covenant; Employee Inventions

      7.1 Acknowledgments by the Employee. The Employee acknowledges that (a)
during the Employment Period and as a part of his employment, the Employee will
be afforded access to


                                       7
<PAGE>

Confidential Information; (b) public disclosure of such Confidential Information
could have an adverse effect on the Company and its business; (c) because the
Employee possesses substantial technical expertise and skill with respect to the
Company's business, the Company desires to obtain exclusive ownership of each
Employee Invention, and the Company will be at a substantial competitive
disadvantage if it fails to acquire exclusive ownership of each Employee
Invention; and (d) the provisions of this Section 7 are reasonable and necessary
to prevent the improper use or disclosure of Confidential Information and to
provide the Company with exclusive ownership of all Employee Inventions.

      7.2 Agreements of the Employee. In consideration of the compensation and
benefits to be paid or provided to the Employee by the Company under this
Agreement, the Employee covenants as follows:

            (a)  Confidentiality.

                  (i) During and following the Employment Period, the Employee
            will hold in confidence the Confidential Information and will not
            disclose it to any Person except with the specific prior written
            consent of the Company or except as otherwise expressly permitted by
            the terms of this Agreement.

                  (ii) Any trade secrets of the Company will be entitled to all
            of the protections and benefits under the Missouri Uniform Trade
            Secrets Act and any other applicable law. If any information that
            the Company deems to be a trade secret is found by a court of
            competent jurisdiction not to be a trade secret for purposes of this
            Agreement, such information will, nevertheless, be considered
            Confidential Information for purposes of this Agreement. The
            Employee hereby waives any requirement that the Company submit proof
            of the economic value of any trade secret or post a bond or other
            security.

                  (iii) None of the foregoing obligations and restrictions
            applies to any part of the Confidential Information that the
            Employee demonstrates was or became generally available to the
            public other than as a result of a disclosure by the Employee or by
            any other Person bound by a confidentiality obligation to the
            Company in respect of such Confidential Information.

                  (iv) The Employee will not remove from the Company's premises
            (except to the extent such removal is for purposes of the
            performance of the Employee's duties at home or while traveling, or
            except as otherwise specifically authorized by the Company) any
            Company document, record, notebook, plan, model, component, device,
            or computer software or code, whether embodied in a disk or in any
            other form (collectively, the "Proprietary Items"). The Employee
            recognizes that, as between the Company and the Employee, all of the
            Proprietary Items, whether or not developed by the Employee, are the
            exclusive property of the Company. Upon termination of this
            Agreement by either party, or upon the request of the Company during
            the Employment Period, the Employee will return to the Company all
            of the


                                       8
<PAGE>

            Proprietary Items in the Employee's possession or subject to
            the Employee's control, and the Employee shall not retain any
            copies, abstracts, sketches, or other physical embodiment of any of
            the Proprietary Items.

            (b) Employee Inventions. Each Employee Invention will belong
      exclusively to the Company. The Employee acknowledges that all Employee
      Inventions are works made for hire and are the property of the Company,
      including any copyrights, patents, or other intellectual property rights
      pertaining thereto. If it is determined that any such works are not works
      made for hire, the Employee hereby assigns to the Company all of the
      Employee's right, title, and interest, including all rights of copyright,
      patent, and other intellectual property rights, to or in such Employee
      Inventions. The Employee will promptly:

                  (i)  disclose to the Company in writing any Employee
            Invention;

                  (ii) assign to the Company or to a party designated by the
            Company, at the Company's request and without additional
            compensation, all of the Employee's right to the Employee Invention
            for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Company such applications,
            assignments, and other documents as the Company may request in order
            to apply for and obtain patents or other registrations with respect
            to any Employee Invention in the United States and any foreign
            jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
            obligations; and

                  (v) give testimony and render any other assistance in support
            of the Company's rights to any Employee Invention.

      Notwithstanding anything to the contrary herein, provisions otherwise
      requiring the Employee to assign to the Company any invention conceived by
      the Employee shall not apply to an invention for which no equipment,
      supplies, facilities or trade secret information of the Company was used
      and which was developed entirely on the Employee's own time, unless the
      invention relates to the business of the Company or to the Company's
      actual or demonstrably anticipated research or development, or the
      invention results from any work performed by the Employee for the Company.

      7.3 Disputes or Controversies. The Employee recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Employee, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

      (but without otherwise participating in the activities of such enterprise)
      if such securities are listed on any national or regional securities
      exchange or have been registered under Section 12(g) of the Securities
      Exchange Act of 1934;

            (b) whether for the Employee's own account or for the account of any
      other Person, at any time during the Employment Period and the
      Post-Employment Period, solicit business of the same or similar type being
      carried on by the Company, from any Person known by the Employee to be a
      customer of the Company, whether or not the Employee had personal contact
      with such Person during and by reason of the Employee's employment with
      the Company;

      Company's relationship with any person, including any person who at any
      time during the Employment Period was an employee, contractor, supplier,
      or customer of the Company;

            (d) at any time during the Employment Period and the Post-Employment
      Period, disparage the Company or any of its shareholders, directors,
      officers, employees, or agents.

      8.3 Divisible Covenants. If any covenant in Section 8.2 is held to be
unreasonable, arbitrary, or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as


                                       10
<PAGE>

a court of competent jurisdiction may determine to be reasonable, not arbitrary,
and not against public policy, will be effective, binding, and enforceable
against the Employee.

      8.4 Extension of Covenants. The period of time applicable to any covenant
in Section 8.2 will be extended by the duration of any violation by the Employee
of such covenant.

      8.5 Notices. The Employee will, while the covenants under Section 8.2 are
in effect, give notice to the Company, within ten days after accepting any other
employment, of the identity of the Employee's new employer. The Company may
notify such new employer that the Employee is bound by this Agreement and, at
the Company's election, furnish such new employer with a copy of this Agreement
or relevant portions thereof.

9.    General Provisions

      9.1 Injunctive Relief and Additional Remedy. The Employee acknowledges
that the injury that would be suffered by the Company as a result of a breach of
the provisions of this Agreement (including any provision of Sections 7 and 8)
would be irreparable and that an award of monetary damages to the Company for
such a breach would be an inadequate remedy. Consequently, the Company will have
the right, in addition to any other rights it may have, to obtain injunctive
relief to restrain any breach or threatened breach or otherwise to specifically
enforce any provision of this Agreement, and the Company will not be obligated
to post bond or other security in seeking such relief. Without limiting the
Company's rights under this Section 9 or any other remedies of the Company, if
the Employee breaches any of the provisions of Section 7 or 8, the Company will
have the right to cease making any payments otherwise due to the Employee under
this Agreement.

      9.2 Covenants of Sections 7 and 8 are Essential and Independent Covenants.
The covenants by the Employee in Sections 7 and 8 are essential elements of this
Agreement, and without the Employee's agreement to comply with such covenants,
the Company would not have entered into this Agreement or employed the Employee.
The Company and the Employee have independently consulted their respective
counsel and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Company. The Employee's covenants in Sections 7 and 8 are
independent covenants and the existence of any claim by the Employee against the
Company, under this Agreement or otherwise, will not excuse the Employee's
breach of any covenant in Section 7 or 8. If the Employee's employment hereunder
expires or is terminated, this Agreement will continue in full force and effect
as is necessary or appropriate to enforce the covenants and agreements of the
Employee in Sections 7 and 8.

      9.3 Representations and Warranties by the Employee. The Employee
represents and warrants to the Company that the execution and delivery by the
Employee of this Agreement do not, and the performance by the Employee of the
Employee's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Employee; or (b) conflict with, result in the breach of any provisions of or the
termination of, or constitute a


                                       11
<PAGE>

default under, any agreement to which the Employee is a party or by which the
Employee is or may be bound.

      9.4 Obligations Contingent on Performance. The obligations of the Company
hereunder, including its obligation to pay the compensation provided for herein,
are contingent upon the Employee's performance of the Employee's obligations
hereunder.

      9.5 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

      9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement shall
inure to the benefit of, and shall be binding upon, the parties hereto and their
respective successors, assigns, heirs, and legal representatives, including any
entity with which the Company may merge or consolidate or to which all or
substantially all of its assets may be transferred. The duties and covenants of
the Employee under this Agreement, being personal, may not be delegated.

      9.7 Notices. All notices and other communications under this Agreement
must be in writing and will be deemed to have been duly given when (a) delivered
by hand (with written confirmation of receipt), (b) sent by facsimile (with
written confirmation of receipt), provided that a copy is mailed by registered
mail, return receipt requested, or (c) when received by the addressee, if sent
by a nationally recognized overnight delivery service (receipt requested), in
the case of the Company to the attention of the President at the Company's
principal business office and in the case of the Employee to the address or

as the Employee may designate by notice to the Company):

2.    Employment Terms and Duties

      2.1 Employment. The Company hereby employs the Employee, and the Employee
hereby accepts employment by the Company, upon the terms and conditions set
forth in this Agreement.

      2.2 Term. Subject to the provisions of Section 6, the term of this
Agreement shall be one year, commencing on February 10, 1998. Thereafter, this

the Employee from engaging in additional activities in connection with personal

      installments according to the Company's customary payroll practices, but
      no less frequently than monthly. The Salary may be increased by the
      Compensation Committee or Board of Directors of the Company during the
      term of this Agreement, and when increased, such higher amount shall then
      be the minimum base annual salary under this Agreement. The Salary shall
      not be reduced below the highest minimum base annual salary fixed from
      time to time by the Compensation Committee or Board of Directors of the
      Company without the Employee's written consent. When increased or
      decreased in accordance with the terms of this Agreement, the new minimum
      base annual salary shall be deemed the Employee's "Salary" for all
      purposes of this Agreement.

            (b) Benefits. The Employee will, during the Employment Period, be
      permitted to participate in such pension, profit sharing, bonus, life
      insurance, disability insurance, hospitalization, major medical, and other
      employee benefit plans of the Company that may be in effect from time to
      time, to the extent the Employee is eligible under the terms of such plans
      (collectively, the "Benefits").

      3.2 Incentive Compensation. The Employee shall be entitled to participate
in an incentive bonus program established by the Board of Directors or the
Compensation Committee of the Board of Directors to measure and reward
management for the financial performance of the Company. The Employee's initial
annual targeted incentive compensation shall be $50,000; provided, however, that
the payment of any incentive compensation shall be at the discretion of the
Compensation Committee of the Board of Directors, which may consider any factors
it deems relevant, including the assessment of the performance of the Employee
and the Company during the relevant time period.

<PAGE>

the request of, or on behalf of, the Company in the performance of the
Employee's duties pursuant to this Agreement, and in accordance with the
Company's employment policies, including reasonable expenses incurred by the
Employee in attending conventions, seminars, and other business meetings, in
appropriate business entertainment activities, and for promotional expenses.

policies of the Company in effect for its employee officers from time to time.

President. The Employee will also be entitled to the paid holidays set forth in
the Company's policies.

6.    Termination

      6.1 Events of Termination. The Employment Period, the Employee's Salary,

Employee under this Agreement will terminate (except as otherwise provided in
this Section 6):

            (a) upon the death of the Employee;

            (b) upon the Disability of the Employee (as defined in Section 6.2)
      immediately upon notice from either party to the other;

            (c) for Cause (as defined in Section 6.3), immediately upon notice
      from the Company to the Employee, or at such later time as such notice may
      specify;

            (d) for Good Reason (as defined in Section 6.4) upon not less than
      thirty days' prior notice from the Employee to the Company; or

            (e) without Cause upon not less than thirty days' notice from the
      Company to the Employee.

      6.2 Definition of "Disability." For purposes of Section 6.1, the Employee
will be deemed to have a "Disability" if, for physical or mental reasons, the
Employee is unable to perform the Employee's duties under this Agreement for 120
consecutive days, or 180 days during any twelve month period, as determined in
accordance with this Section 6.2. The Disability of the Employee will be
determined by a medical doctor selected by written agreement of the Company and
the Employee upon the request of either party by notice to the other. If the
Company and the Employee cannot agree on the selection of a medical doctor, each
of them will select a medical doctor and the two medical doctors will select a
third medical doctor who will determine whether the Employee has a Disability.
The determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Employee must submit to a reasonable number of
examinations by the medical doctor making the determination of Disability under
this Section 6.2, and to other specialists designated by such medical doctor,
and the Employee hereby authorizes the disclosure and release to the Company of
such determination and all supporting medical records. If


                                       5
<PAGE>

the Employee is not legally competent, the Employee's legal guardian or duly
authorized attorney-in-fact will act in the Employee's stead under this Section
6.2 for the purposes of submitting the Employee to the examinations, and
providing the authorization of disclosure, required under this Section 6.2.

      6.3 Definition of "Cause." For purposes of Section 6.1, the term "Cause"
means: (a) the Employee's breach of a material obligation under this Agreement;
(b) the Employee's failure to adhere in any material respect to any written
Company policy if such policy is material to the effective performance by the
Employee of his duties under this Agreement, and if the Employee has been given
a reasonable opportunity to cure his failure to comply within the thirty-day
period preceding termination of this Agreement, provided that if the Employee
cures his failure to comply with such a policy and then fails again to comply
with the same policy, no further opportunity to cure that failure shall be
required; (c) the appropriation (or attempted appropriation) of a material
business opportunity of the Company, including attempting to secure or securing
any personal profit in connection with any transaction entered into on behalf of
the Company (other than through stock options, bonuses and other incentives
provided by the Company to the Employee); (d) the misappropriation (or attempted
misappropriation) of any of the Company's funds or property; or (e) the
conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, or a crime involving moral turpitude, dishonesty, or
fraud.

      6.4 Definition of "Good Reason." For purposes of Section 6.1, the term
"Good Reason" shall mean (a) a substantial reduction in the Employee's duties or
responsibilities, (b) any reduction in Employee's Salary, or (c) relocation of
the Employee's primary workplace to a location that is greater than 35 miles
from the Employee's current workplace, in each case which is not cured within 30
days following the Company's receipt of written notice from the Employee
describing the event constituting Good Reason.

      6.5 Termination Pay. Effective upon the expiration or termination of this
Agreement, the Company will be obligated to pay the Employee (or, in the event
of his death, his designated beneficiary as defined below) only such
compensation as is provided in this Section 6.5. For purposes of this Section
6.5 the Employee's designated beneficiary will be such individual beneficiary or
trust, located at such address, as the Employee may designate by notice to the
Company from time to time or, if the Employee fails to give notice to the
Company of such a beneficiary, the Employee's estate. Notwithstanding the
preceding sentence, the Company will have no duty, in any circumstances, to
attempt to open an estate on behalf of the Employee, to determine whether any
beneficiary designated by the Employee is alive or to ascertain the address of
any such beneficiary, to determine the existence of any trust, to determine
whether any Person purporting to act as the Employee's personal representative
(or the trustee of a trust established by the Employee) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee.

            (a) Termination by the Employee for Good Reason or by the Company
      without Cause. If the Employee terminates this Agreement for Good Reason,
      or if the Company terminates this Agreement other than for Cause (but not
      because of the Disability or death


                                       6
<PAGE>

      of the Employee), or if the Company notifies the Employee in accordance
      with Section 2.2 that this Agreement will not be renewed as of an
      applicable expiration date, the Company will pay the Employee (i) the
      Employee's Salary for the remainder, if any, of the calendar month in
      which such termination is effective and for twenty-four consecutive
      calendar months thereafter, (ii) the amount of the Employee's targeted
      incentive compensation for the year during which the termination is
      effective (prorated for the period from the beginning of the year until
      the effective date of termination), and (iii) the sum of two times the
      amount of targeted incentive compensation for the year in which the
      termination was effective (such amount to be determined as if the Employee
      had been employed for the entire year and not be prorated as described in
      clause (ii) above), payable in equal monthly installments over the
      Post-Employment Period. Notwithstanding the preceding sentence, if the
      Employee obtains other employment prior to the end of the twenty-four
      months following the month in which the termination or expiration is
      effective, he must promptly give notice thereof to the Company, and the
      payments under this Agreement for any period after the Employee obtains
      other employment will be reduced by the amount of the cash compensation
      received and to be received by the Employee from the Employee's other
      employment for services performed during such period.

            (b) Termination by the Company for Cause. If the Company terminates
      this Agreement for Cause, the Employee will be entitled to receive his
      Salary only through the date such termination is effective.

            (c) Termination upon Disability. If this Agreement is terminated by
      either party as a result of the Employee's Disability, as determined under
      Section 6.2, the Company will pay the Employee his Salary through the
      remainder of the calendar month during which such termination is effective
      and for the lesser of (i) six consecutive months thereafter, or (ii) the
      period until disability insurance benefits commence under any disability
      insurance coverage furnished by the Company to the Employee.

            (d) Termination upon Death. If this Agreement is terminated because
      of the Employee's death, the Employee will be entitled to receive his
      Salary through the end of the calendar month in which his death occurs.

            (e) Benefits. Except as otherwise required by law, the Employee's
      accrual of, or participation in plans providing for, the Benefits will
      cease at the effective date of the termination of this Agreement, and the
      Employee will be entitled to accrued Benefits pursuant to such plans only
      as provided in such plans.

7.    Non-Disclosure Covenant; Employee Inventions

      7.1 Acknowledgments by the Employee. The Employee acknowledges that (a)
during the Employment Period and as a part of his employment, the Employee will
be afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Company and its
business; (c) because the Employee possesses substantial technical expertise and
skill with respect to the Company's business, the Company desires to obtain


                                       7
<PAGE>

exclusive ownership of each Employee Invention, and the Company will be at a
substantial competitive disadvantage if it fails to acquire exclusive ownership
of each Employee Invention; and (d) the provisions of this Section 7 are
reasonable and necessary to prevent the improper use or disclosure of
Confidential Information and to provide the Company with exclusive ownership of
all Employee Inventions.

      7.2 Agreements of the Employee. In consideration of the compensation and
benefits to be paid or provided to the Employee by the Company under this
Agreement, the Employee covenants as follows:

            (a)  Confidentiality.

                  (i) During and following the Employment Period, the Employee
            will hold in confidence the Confidential Information and will not
            disclose it to any Person except with the specific prior written
            consent of the Company or except as otherwise expressly permitted by
            the terms of this Agreement.

                  (ii) Any trade secrets of the Company will be entitled to all
            of the protections and benefits under the Missouri Uniform Trade
            Secrets Act and any other applicable law. If any information that
            the Company deems to be a trade secret is found by a court of
            competent jurisdiction not to be a trade secret for purposes of this
            Agreement, such information will, nevertheless, be considered
            Confidential Information for purposes of this Agreement. The
            Employee hereby waives any requirement that the Company submit proof
            of the economic value of any trade secret or post a bond or other
            security.

                  (iii) None of the foregoing obligations and restrictions
            applies to any part of the Confidential Information that the
            Employee demonstrates was or became generally available to the
            public other than as a result of a disclosure by the Employee or by
            any other Person bound by a confidentiality obligation to the
            Company in respect of such Confidential Information.

                  (iv) The Employee will not remove from the Company's premises
            (except to the extent such removal is for purposes of the
            performance of the Employee's duties at home or while traveling, or
            except as otherwise specifically authorized by the Company) any
            Company document, record, notebook, plan, model, component, device,
            or computer software or code, whether embodied in a disk or in any
            other form (collectively, the "Proprietary Items"). The Employee
            recognizes that, as between the Company and the Employee, all of the
            Proprietary Items, whether or not developed by the Employee, are the
            exclusive property of the Company. Upon termination of this
            Agreement by either party, or upon the request of the Company during
            the Employment Period, the Employee will return to the Company all
            of the Proprietary Items in the Employee's possession or subject to
            the Employee's control, and the Employee shall not retain any
            copies, abstracts, sketches, or other physical embodiment of any of
            the Proprietary Items.


                                       8
<PAGE>

            (b) Employee Inventions. Each Employee Invention will belong
      exclusively to the Company. The Employee acknowledges that all Employee
      Inventions are works made for hire and are the property of the Company,
      including any copyrights, patents, or other intellectual property rights
      pertaining thereto. If it is determined that any such works are not works
      made for hire, the Employee hereby assigns to the Company all of the
      Employee's right, title, and interest, including all rights of copyright,
      patent, and other intellectual property rights, to or in such Employee
      Inventions. The Employee will promptly:

                  (i) disclose to the Company in writing any Employee Invention;

                  (ii) assign to the Company or to a party designated by the
            Company, at the Company's request and without additional
            compensation, all of the Employee's right to the Employee Invention
            for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Company such applications,
            assignments, and other documents as the Company may request in order
            to apply for and obtain patents or other registrations with respect
            to any Employee Invention in the United States and any foreign
            jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
            obligations; and

                  (v) give testimony and render any other assistance in support
            of the Company's rights to any Employee Invention.

      Notwithstanding anything to the contrary herein, provisions otherwise
      requiring the Employee to assign to the Company any invention conceived by
      the Employee shall not apply to an invention for which no equipment,
      supplies, facilities or trade secret information of the Company was used
      and which was developed entirely on the Employee's own time, unless the
      invention relates to the business of the Company or to the Company's
      actual or demonstrably anticipated research or development, or the
      invention results from any work performed by the Employee for the Company.

      7.3 Disputes or Controversies. The Employee recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Employee, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

8.    Non-Competition and Non-Interference

      8.1 Acknowledgments by the Employee. The Employee acknowledges that: (a)
the services to be performed by him under this Agreement are of a special,
unique, unusual,


                                       9
<PAGE>

extraordinary, and intellectual character; (b) the Company competes with other
businesses that are or could be located in any part of the Territory; and (c)
the provisions of this Section 8 are reasonable and necessary to protect the
Company's business.

      8.2 Covenants of the Employee. In consideration of the acknowledgments by
the Employee, and in consideration of the compensation and benefits to be paid
or provided to the Employee by the Company, the Employee covenants that he will
not, directly or indirectly:

            (a) during the Employment Period, except in the course of his
      employment hereunder, and during the Post-Employment Period, engage or
      invest in, own, manage, operate, finance, control, or participate in the
      ownership, management, operation, financing, or control of, be employed
      by, associated with, or in any manner connected with, lend the Employee's
      name or any similar name to, lend Employee's credit to or render services
      or advice to, any Competitive Business within the Territory; provided,
      however, that the Employee may purchase or otherwise acquire up to (but
      not more than) one percent of any class of securities of any enterprise
      (but without otherwise participating in the activities of such enterprise)
      if such securities are listed on any national or regional securities
      exchange or have been registered under Section 12(g) of the Securities
      Exchange Act of 1934;

            (b) whether for the Employee's own account or for the account of any
      other Person, at any time during the Employment Period and the
      Post-Employment Period, solicit business of the same or similar type being
      carried on by the Company, from any Person known by the Employee to be a
      customer of the Company, whether or not the Employee had personal contact
      with such Person during and by reason of the Employee's employment with
      the Company;

            (c) whether for the Employee's own account or the account of any
      other Person at any time during the Employment Period and the
      Post-Employment Period, solicit, employ, or otherwise engage as an
      employee, independent contractor, or otherwise, any person who is or was
      an employee of the Company at any time during the Employment Period or in
      any manner induce or attempt to induce any employee of the Company to
      terminate his or her employment with the Company; or at any time during
      the Employment Period and the Post-Employment Period, interfere with the
      Company's relationship with any person, including any person who at any
      time during the Employment Period was an employee, contractor, supplier,
      or customer of the Company;

            (d) at any time during the Employment Period and the Post-Employment
      Period, disparage the Company or any of its shareholders, directors,
      officers, employees, or agents.

      8.3 Divisible Covenants. If any covenant in Section 8.2 is held to be
unreasonable, arbitrary, or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as a court of
competent jurisdiction may determine to be reasonable, not arbitrary, and not
against public policy, will be effective, binding, and enforceable against the
Employee.


                                       10
<PAGE>

      8.4 Extension of Covenants. The period of time applicable to any covenant
in Section 8.2 will be extended by the duration of any violation by the Employee
of such covenant.

      8.5 Notices. The Employee will, while the covenants under Section 8.2 are
in effect, give notice to the Company, within ten days after accepting any other
employment, of the identity of the Employee's new employer. The Company may
notify such new employer that the Employee is bound by this Agreement and, at
the Company's election, furnish such new employer with a copy of this Agreement
or relevant portions thereof.

9.    General Provisions

      9.1 Injunctive Relief and Additional Remedy. The Employee acknowledges
that the injury that would be suffered by the Company as a result of a breach of
the provisions of this Agreement (including any provision of Sections 7 and 8)
would be irreparable and that an award of monetary damages to the Company for
such a breach would be an inadequate remedy. Consequently, the Company will have
the right, in addition to any other rights it may have, to obtain injunctive
relief to restrain any breach or threatened breach or otherwise to specifically
enforce any provision of this Agreement, and the Company will not be obligated
to post bond or other security in seeking such relief. Without limiting the
Company's rights under this Section 9 or any other remedies of the Company, if
the Employee breaches any of the provisions of Section 7 or 8, the Company will
have the right to cease making any payments otherwise due to the Employee under
this Agreement.

      9.2 Covenants of Sections 7 and 8 are Essential and Independent Covenants.
The covenants by the Employee in Sections 7 and 8 are essential elements of this
Agreement, and without the Employee's agreement to comply with such covenants,
the Company would not have entered into this Agreement or employed the Employee.
The Company and the Employee have independently consulted their respective
counsel and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Company. The Employee's covenants in Sections 7 and 8 are
independent covenants and the existence of any claim by the Employee against the
Company, under this Agreement or otherwise, will not excuse the Employee's
breach of any covenant in Section 7 or 8. If the Employee's employment hereunder
expires or is terminated, this Agreement will continue in full force and effect
as is necessary or appropriate to enforce the covenants and agreements of the
Employee in Sections 7 and 8.

      9.3 Representations and Warranties by the Employee. The Employee
represents and warrants to the Company that the execution and delivery by the
Employee of this Agreement do not, and the performance by the Employee of the
Employee's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Employee; or (b) conflict with, result in the breach of any provisions of or the
termination of, or constitute a default under, any agreement to which the
Employee is a party or by which the Employee is or may be bound.


                                       11
<PAGE>

      9.4 Obligations Contingent on Performance. The obligations of the Company
hereunder, including its obligation to pay the compensation provided for herein,
are contingent upon the Employee's performance of the Employee's obligations
hereunder.

      9.5 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

      9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement shall
inure to the benefit of, and shall be binding upon, the parties hereto and their
respective successors, assigns, heirs, and legal representatives, including any
entity with which the Company may merge or consolidate or to which all or
substantially all of its assets may be transferred. The duties and covenants of
the Employee under this Agreement, being personal, may not be delegated.

      9.7 Notices. All notices and other communications under this Agreement
must be in writing and will be deemed to have been duly given when (a) delivered
by hand (with written confirmation of receipt), (b) sent by facsimile (with
written confirmation of receipt), provided that a copy is mailed by registered
mail, return receipt requested, or (c) when received by the addressee, if sent
by a nationally recognized overnight delivery service (receipt requested), in
the case of the Company to the attention of the President at the Company's
principal business office and in the case of the Employee to the address or
facsimile number set forth below (or to such other address or facsimile number
as the Employee may designate by notice to the Company):

      9.8 Entire Agreement; Amendments. This Agreement contains the entire
agreement between the parties with respect to its subject matter and supersedes
all prior agreements and understandings, oral or written, between the parties
with respect to its subject matter. This Agreement may not be amended orally,
but only by an agreement in writing signed by each of the parties to this
Agreement.

      9.9 Governing Law. This Agreement will be governed by the laws of the
State of Missouri without regard to conflicts of laws principles.

            (b) The Swing Line Lender, at any time and from time to time in its
sole and absolute discretion may, on behalf of the Borrower (which hereby
irrevocably directs the Swing Line Lender to act on its behalf), on one Business
Day's notice given by the Swing Line Lender no later than 12:00 Noon, New York
City time, request each Revolving Credit Lender to make, and each Revolving
Credit Lender hereby agrees to make, a Revolving Credit Loan, in an amount equal
to such Revolving Credit Lender's Revolving Credit Percentage of the aggregate
amount of the Swing Line Loans (the "Refunded Swing Line Loans") outstanding on
the date of such notice, to repay the Swing Line Lender. Each Revolving Credit
Lender shall make the amount of such Revolving Credit Loan available to the
Administrative Agent at the Funding Office in immediately available funds, not
later than 10:00 A.M., New York City time, one Business Day after the date of
such notice. The proceeds of such Revolving Credit Loans shall be immediately
made available by the Administrative Agent to the Swing Line Lender for
application by the Swing Line Lender to the repayment of the Refunded Swing Line
Loans.

            (c) If prior to the time a Revolving Credit Loan would have
otherwise been made pursuant to Section 2.7(b), one of the events described in
Section 7(f) shall have occurred and be continuing with respect to the Borrower
or if for any other reason, as determined by the Swing Line Lender in its sole
discretion, Revolving Credit Loans may not be made as contemplated by Section
2.7(b), each Revolving Credit Lender shall, on the date such Revolving Credit
Loan was to have been made pursuant to the notice referred to in Section 2.7(b)
(the "Refunding Date"),

<PAGE>
                                       31

Participation Amount") equal to (i) such Revolving Credit Lender's Revolving
Credit Percentage times (ii) the sum of the aggregate principal amount of Swing
Line Loans then outstanding which were to have been repaid with such Revolving
Credit Loans.

            (d) Whenever, at any time after the Swing Line Lender has received
from any Revolving Credit Lender such Lender's Swing Line Participation Amount,
the Swing Line Lender receives any payment on account of the Swing Line Loans,
the Swing Line Lender will distribute to such Lender its Swing Line
Participation Amount (appropriately adjusted, in the case of interest payments,
to reflect the period of time during which such Lender's participating interest
was outstanding and funded and, in the case of principal and interest payments,
to reflect such Lender's pro rata portion of such payment if such payment is not
sufficient to pay the principal of and interest on all Swing Line Loans then
due); provided, however, that in the event that such payment received by the
Swing Line Lender is required to be returned, such Revolving Credit Lender will
return to the Swing Line Lender any portion thereof previously distributed to it
by the Swing Line Lender.

            (e) Each Revolving Credit Lender's obligation to make the Loans
referred to in Section 2.7(b) and to purchase participating interests pursuant
to Section 2.7(c) shall be absolute and unconditional and shall not be affected
by any circumstance, including, without limitation, (i) any setoff,
counterclaim, recoupment, defense or other right which such Revolving Credit
Lender or the Borrower may have against the Swing Line Lender, the Borrower or
any other Person for any reason whatsoever, (ii) the occurrence or continuance
of a Default or an Event of Default or the failure to satisfy any of the other
conditions specified in Section 4, (iii) any adverse change in the condition
(financial or otherwise) of the Borrower, (iv) any breach of this Agreement or
any other Credit Document by the Borrower, any other Credit Party or any other
Revolving Credit Lender, or (v) any other circumstance, happening or event
whatsoever, whether or not similar to any of the foregoing.

unconditionally promises to pay to the Administrative Agent for the account of
the appropriate Revolving Credit Lender or Term Loan Lender, as the case may be,
(i) the then unpaid principal amount of each Revolving Credit Loan of such
Revolving Credit Lender on the Revolving Credit Termination Date (or such
earlier date on which the Loans become due and payable pursuant to Section 7),
(ii) the then unpaid principal amount of each Swing Line Loan of such Swing Line
Lender on the Revolving Credit Termination Date (or such earlier date on which
the Loans become due and payable pursuant to Section 7) and (iii) the principal
amount of each Term Loan of such Term Loan Lender in installments according to
the amortization schedule set forth in Section 2.3 (or on such earlier date on
which the Loans become due and payable pursuant to Section 7). The Borrower
hereby further agrees to pay interest on the unpaid principal amount of the
Loans from time to time outstanding from the date hereof until payment in full
thereof at the rates per annum, and on the dates, set forth in Section 2.15.

of principal and interest payable and paid to such Lender from time to time
under this Agreement.

            (c) The Administrative Agent, on behalf of the Borrower, shall

Period applicable thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder
and (iii) both the amount of any sum received by the Administrative Agent
hereunder from the Borrower and each Lender's share thereof.

            (d) The entries made in the Register and the accounts of each Lender
maintained pursuant to Section 2.8(b) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of the Borrower therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain the Register or
any such account, or any error therein, shall not in any manner affect the
obligation of the Borrower to repay (with applicable interest) the Loans made to
such Borrower by such Lender in accordance with the terms of this Agreement.

            (e) The Borrower agrees that, upon the request to the Administrative

Available Commitment of such Lender during the fiscal quarter then ended (or, if
applicable, shorter period commencing with the date upon which such Lender's
Commitment was in effect), payable quarterly in arrears on the last day of each
March, June, September and December and on (in the case of the Revolving Credit
Lenders) the Revolving Credit Termination Date or (in the case of the Term
Lenders) the Term Loan Commitment Termination Date, commencing on the first of
such dates to occur after the date hereof.

            (b) The Borrower agrees to pay to the Administrative Agent the fees
in the amounts and on the dates from time to time agreed to in writing by the
Borrower and the Administrative Agent.

            2.10 Termination or Reduction of Commitments. The Borrower shall
have the right, upon not less than three Business Days' notice to the
Administrative Agent, to terminate the Commitments or, from time to time, to
reduce the amount of the Commitments; provided that no such termination or
reduction of Revolving Credit Commitments shall be permitted if, after

<PAGE>
                                       33


giving effect thereto and to any prepayments of the Revolving Credit Loans and
Swing Line Loans made on the effective date thereof, the Total Revolving
Extensions of Credit would exceed the Total Revolving Credit Commitments. Any
such reduction shall be in an amount equal to $1,000,000, or a whole multiple
thereof, and shall reduce permanently the relevant Commitments then in effect.

            2.11 Optional Prepayments. The Borrower may at any time and from
time to time prepay the Loans, in whole or in part, without premium or penalty,
upon irrevocable notice delivered to the Administrative Agent at least three
Business Days prior thereto in the case of Eurodollar Loans and at least one
Business Day prior thereto in the case of Base Rate Loans, which notice shall
specify the date and amount of prepayment and whether the prepayment is of
Eurodollar Loans or Base Rate Loans; provided that if a Eurodollar Loan is
prepaid on any day other than the last day of the Interest Period applicable
thereto, the Borrower shall also pay any amounts owing pursuant to Section 2.21.
Upon receipt of any such notice the Administrative Agent shall promptly notify
each relevant Lender thereof. If any such notice is given, the amount specified
in such notice shall be due and payable on the date specified therein, together
with (except in the case of Revolving Credit Loans which are Base Rate Loans and
Swing Line Loans) accrued interest to such date on the amount prepaid. Partial
prepayments of Revolving Credit Loans and Term Loans shall be in an aggregate
principal amount of $1,000,000 or a whole multiple thereof. Partial prepayments
of Swing Line Loans shall be in an aggregate principal amount of $100,000 or a
whole multiple thereof.

            2.12 Mandatory Prepayments and Commitment Reductions. (a) If on any
date the Company or any of its Subsidiaries shall receive Net Cash Proceeds from
any Asset Sale or Recovery Event then, unless a Reinvestment Notice shall be
delivered in respect thereof, such Net Cash Proceeds shall be applied on such
date toward the prepayment of the Term Loans and the reduction of the Revolving
Credit Commitments as set forth in Section 2.12(c); provided that,
notwithstanding the foregoing, on each Reinvestment Prepayment Date, an amount
equal to the Reinvestment Prepayment Amount with respect to the relevant
Reinvestment Event shall be applied toward the prepayment of the Term Loans and
the reduction of the Commitments as set forth in Section 2.12(c).

            (b) If, for any fiscal year ending on or after December 31, 2003,
there shall be Excess Cash Flow, the Borrower shall, on the relevant Excess Cash
Flow Application Date, apply the ECF Percentage of such Excess Cash Flow toward
the prepayment of the Term Loans and the reduction of the Revolving Credit
Commitments as set forth in Section 2.12(c). Each such prepayment and commitment
reduction shall be made on a date (an "Excess Cash Flow Application Date") no
later than five days after the earlier of (i) the latest date on which the
financial statements of the Company referred to in Section 5.1(a), for the
fiscal year with respect to which such prepayment is made, are required to be
delivered to the Lenders and (ii) the date such financial statements are
actually delivered.

            (c) Amounts to be applied in connection with prepayments and
Commitment reductions made pursuant to this Section shall be applied, first, to
reduce permanently the unused portion (if any) of Term Loan Commitments, second,
to the prepayment of the Term Loans and,

<PAGE>
                                       34


finally, to reduce permanently the Revolving Credit Commitments. Any such
reduction of the Revolving Credit Commitments shall be accompanied by prepayment
of the Revolving Credit Loans and/or Swing Line Loans to the extent, if any,
that the Total Revolving Extensions of Credit exceed the amount of the Total
Revolving Credit Commitments as so reduced. The application of any prepayment
pursuant to this Section shall be made, first, to Base Rate Loans and, second,
to Eurodollar Loans. Each prepayment of the Loans under this Section (except in
the case of Revolving Credit Loans that are Base Rate Loans and Swing Line
Loans) shall be accompanied by accrued interest to the date of such prepayment
on the amount prepaid.

            2.13 Conversion and Continuation Options. (a) The Borrower may elect
from time to time to convert Eurodollar Loans to Base Rate Loans by giving the
Administrative Agent at least two Business Days' prior irrevocable notice of
such election; provided that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest Period with respect thereto. The Borrower
may elect from time to time to convert Base Rate Loans to Eurodollar Loans by
giving the Administrative Agent at least three Business Days' prior irrevocable
notice of such election (which notice shall specify the length of the initial
Interest Period therefor); provided that no Base Rate Loan under a particular
Facility may be converted into a Eurodollar Loan when any Event of Default has
occurred and is continuing and the Administrative Agent or the Majority Facility
Lenders in respect of such Facility have determined in its or their sole
discretion not to permit such conversion. Upon receipt of any such notice the
Administrative Agent shall promptly notify each relevant Lender thereof.

            (b) Any Eurodollar Loan may be continued as such upon the expiration
of the then current Interest Period with respect thereto by the Borrower giving
irrevocable notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in Section 1.1, of
the length of the next Interest Period to be applicable to such Loans; provided
that no Eurodollar Loan under a particular Facility may be continued as such (i)
when any Event of Default has occurred and is continuing and the Administrative
Agent has or the Majority Facility Lenders in respect of such Facility have
determined in its or their sole discretion not to permit such continuations or
(ii) after the date that is one month prior to the final scheduled termination
or maturity date of such Facility, and provided, further, that if the Borrower
shall fail to give any required notice as described above in this paragraph or
if such continuation is not permitted pursuant to the preceding proviso such
Loans shall be automatically converted to Base Rate Loans on the last day of
such then expiring Interest Period. Upon receipt of any such notice the
Administrative Agent shall promptly notify each relevant Lender thereof.

            2.14 Minimum Amounts and Maximum Number of Eurodollar Tranches.
Notwithstanding anything to the contrary in this Agreement, all borrowings,
conversions, continuations and optional prepayments of Eurodollar Loans
hereunder and all selections of Interest Periods hereunder shall be in such
amounts and be made pursuant to such elections so that, (a) after giving effect
thereto, the aggregate principal amount of the Eurodollar Loans comprising each
Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $100,000
in excess thereof and (b) no more than 15 Eurodollar Tranches shall be
outstanding at any one time.

<PAGE>
                                       35


            2.15 Interest Rates and Payment Dates. (a) Each Eurodollar Loan
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

            (b) Each Base Rate Loan shall bear interest at a rate per annum
equal to the Base Rate plus the Applicable Margin.

            (c) (i) If all or a portion of the principal amount of any Loan
shall not be paid when due (whether at the stated maturity, by acceleration or
otherwise), such overdue amount shall bear interest at a rate per annum which is
equal to the rate that would otherwise be applicable thereto pursuant to the
foregoing provisions of this Section plus 2% and (ii) if all or a portion of any
interest payable on any Loan or any commitment fee or other amount payable
hereunder shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such overdue amount shall bear interest at a rate
per annum equal to the rate then applicable to Base Rate Loans under the
relevant Facility plus 2%, in each case, with respect to clauses (i) and (ii)
above, from the date of such non-payment until such amount is paid in full (as
well after as before judgment).

            (d) Interest shall be payable in arrears on each Interest Payment
Date; provided that interest accruing pursuant to paragraph (c) of this Section
shall be payable from time to time on demand.

            2.16 Computation of Interest and Fees. (a) Interest, fees and
commissions payable pursuant hereto shall be calculated on the basis of a
360-day year for the actual days elapsed, except that, with respect to Base Rate
Loans the rate of interest on which is calculated on the basis of the Prime
Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-,
as the case may be) day year for the actual days elapsed. The Administrative
Agent shall as soon as practicable notify the Borrower and the relevant Lenders
of each determination of a Eurodollar Rate. Any change in the interest rate on a
Loan resulting from a change in the Base Rate or the Eurocurrency Reserve
Requirements shall become effective as of the opening of business on the day on
which such change becomes effective. The Administrative Agent shall as soon as
practicable notify the Borrower and the relevant Lenders of the effective date
and the amount of each such change in interest rate.

            (b) Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Lenders in the absence of manifest error. The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to Section 2.15(a).

            2.17 Inability to Determine Interest Rate. If prior to the first day
of any Interest Period:

            (a) the Administrative Agent shall have determined (which
      determination shall be conclusive and binding upon the Borrower) that, by
      reason of circumstances affecting the

<PAGE>
                                       36


      interbank eurodollar market arising after the date hereof, adequate and
      reasonable means do not exist for ascertaining the Eurodollar Rate for
      such Interest Period, or

            (b) the Administrative Agent shall have received notice from the
      Majority Facility Lenders in respect of the relevant Facility that, by
      reason of circumstances arising after the date hereof affecting the
      interbank eurodollar market, the Eurodollar Rate determined or to be
      determined for such Interest Period will not adequately and fairly reflect
      the cost to such Lenders (as conclusively certified by such Lenders) of
      making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the relevant Lenders as soon as practicable thereafter. If such
notice is given (x) any Eurodollar Loans under the relevant Facility requested
to be made on the first day of such Interest Period shall be made as Base Rate
Loans, (y) any Loans under the relevant Facility that were to have been
converted on the first day of such Interest Period to Eurodollar Loans shall be
continued as Base Rate Loans and (z) any outstanding Eurodollar Loans under the
relevant Facility shall be converted, on the last day of the then current
Interest Period with respect thereto, to Base Rate Loans. Until such notice has
been withdrawn by the Administrative Agent, no further Eurodollar Loans under
the relevant Facility shall be made or continued as such, nor shall the Borrower
have the right to convert Loans under the relevant Facility to Eurodollar Loans.

            2.18 Pro Rata Treatment and Payments. (a) Each borrowing by the
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee and any reduction of the Commitments of the Lenders shall be
made pro rata according to the respective Term Loan Percentages or Revolving
Credit Percentages, as the case may be, of the relevant Lenders. Each payment
(other than prepayments) in respect of principal or interest in respect of the
Loans, each payment in respect of fees payable hereunder shall be applied to the
amounts of such obligations owing to the Lenders pro rata according to the
respective amounts then due and owing to the Lenders.

            (b) Each optional prepayment pursuant to Section 2.11 in respect of
the Term Loans shall be applied to the installments of such Loans, in each case
as the Borrower shall specify.

            (c) Each payment (including each prepayment) of the Loans
outstanding under the Term Loan Facility shall be allocated among the Lenders
holding such Loans pro rata based on the principal amount of such Loans held by
such Lenders, and shall be applied to the installments of such Loans pro rata
based on the remaining outstanding principal amount of such installments.
Amounts prepaid on account of the Term Loans may not be reborrowed.

            (d) Each payment (including each prepayment) by the Borrower on
account of principal of and interest on the Revolving Credit Loans shall be made
pro rata according to the respective outstanding principal amounts of the
Revolving Credit Loans then held by the Revolving Credit Lenders.

<PAGE>
                                       37


            (e) All payments (including prepayments) to be made by the Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 12:00 Noon,
New York City time, on the due date thereof to the Administrative Agent, for the
account of the respective Lenders, at the Payment Office, in Dollars and in
immediately available funds. The Administrative Agent shall distribute such
payments to the respective Lenders promptly upon receipt in like funds as
received. If any payment hereunder (other than payments on the Eurodollar Loans)
becomes due and payable on a day other than a Business Day, such payment shall
be extended to the next succeeding Business Day. If any payment on a Eurodollar
Loan becomes due and payable on a day other than a Business Day, the maturity
thereof shall be extended to the next succeeding Business Day unless the result
of such extension would be to extend such payment into another calendar month,
in which event such payment shall be made on the immediately preceding Business
Day. In the case of any extension of any payment of principal pursuant to the
preceding two sentences, interest thereon shall be payable at the then
applicable rate during such extension.

            (f) Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount. If such amount is not made available to the Administrative
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to the Administrative Agent, on demand, such amount with interest thereon at a
rate equal to the daily average Federal Funds Effective Rate for the period
until such Lender makes such amount immediately available to the Administrative
Agent. A certificate of the Administrative Agent submitted to any Lender with
respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender's share of such borrowing is not made
available to the Administrative Agent by such Lender within three Business Days
of such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to
Base Rate Loans under the relevant Facility, on demand, from the Borrower.

            (g) Unless the Administrative Agent shall have been notified in
writing by the Borrower prior to the date of any payment being made hereunder
that the Borrower will not make such payment to the Administrative Agent, the
Administrative Agent may assume that the Borrower is making such payment, and
the Administrative Agent may, but shall not be required to, in reliance upon
such assumption, make available to the Lenders their respective pro rata shares
of a corresponding amount. If such payment is not made to the Administrative
Agent by the Borrower within three Business Days of such required date, the
Administrative Agent shall be entitled to recover, on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such amount with interest thereon at the rate per annum equal to the daily
average Federal Funds Effective Rate. Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

                                       38


            2.19 Requirements of Law. (a) If the adoption of or any change in
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority, in each
case occurring or made subsequent to the date hereof:

            (i) shall subject any Lender to any tax of any kind whatsoever with
      respect to this Agreement or any Eurodollar Loan made by it, or change the
      basis of taxation of payments to such Lender in respect thereof (except
      for Non-Excluded Taxes covered by Section 2.20 and changes in the rate of
      tax on the overall net income of such Lender);

            (ii) shall impose, modify or hold applicable any reserve, special
      deposit, compulsory loan or similar requirement against assets held by,
      deposits or other liabilities in or for the account of, advances, loans or
      other extensions of credit by, or any other acquisition of funds by, any
      office of such Lender which is not otherwise included in the determination
      of the Eurodollar Rate hereunder (including, without limitation, any
      Eurocurrency Reserve Requirement); or

            (iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender deems to be material, of making, converting into,
continuing or maintaining Eurodollar Loans, or to reduce any amount receivable
hereunder in respect thereof, then, in any such case, the Borrower shall
promptly pay such Lender, upon its demand, any additional amounts necessary to
compensate such Lender for such increased cost or reduced amount receivable. If
any Lender becomes entitled to claim any additional amounts pursuant to this
Section, it shall promptly notify the Borrower (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.

            (b) If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any Governmental
Authority, in each case occurring or made subsequent to the date hereof, shall
have the effect of reducing the rate of return on such Lender's or such
corporation's capital as a consequence of its obligations hereunder to a level
below that which such Lender or such corporation could have achieved but for
such adoption, change or compliance (taking into consideration such Lender's or
such corporation's policies with respect to capital adequacy) by an amount
deemed by such Lender to be material, then from time to time, after submission
by such Lender to the Borrower (with a copy to the Administrative Agent) of a
written request therefor, the Borrower shall pay to such Lender such additional
amount or amounts as will compensate such Lender for such reduction; provided
that the Borrower shall not be required to compensate a Lender pursuant to this
paragraph for any increased costs or reductions incurred more than 120 days
prior to the date that such Lender notifies the Borrower of the Requirement of
Law giving rise to such increased costs or reductions and of such Lender's
intention to claim compensation therefor; and provided, further, that, if the
circumstances giving rise to such claim have a

<PAGE>
                                       39


retroactive effect, then such 120 day period shall be extended to include the
period of such retroactive effect.

            (c) A certificate as to any additional amounts payable pursuant to
this Section submitted by any Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error. The
obligations of the Borrower pursuant to this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

            2.20 Taxes. (a) All payments made by the Borrower under this
Agreement shall be made free and clear of, and without deduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, excluding net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on any Agent or any Lender as a result of a present or
former connection between such Agent or such Lender and the jurisdiction of the
Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from
such Agent or such Lender having executed, delivered or performed its
obligations or received a payment under, or enforced, this Agreement or any
other Credit Document). If any such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions or withholdings ("Non-Excluded Taxes") or Other Taxes
are required to be withheld from any amounts payable to any Agent or any Lender
hereunder, the amounts so payable to such Agent or such Lender shall be
increased to the extent necessary to yield to such Agent or such Lender (after
payment of all Non-Excluded Taxes and Other Taxes) interest or any such other
amounts payable hereunder at the rates or in the amounts specified in this
Agreement; provided, however, that the Borrower shall not be required to
increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender's failure to comply with the
requirements of paragraph (d) or (e) of this Section or (ii) that are United
States withholding taxes imposed on amounts payable to such Lender at the time
the Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the Borrower with respect to such Non-Excluded Taxes
pursuant to Section 2.20(a).

            (b) In addition, the Borrower shall pay any Other Taxes to the
relevant Governmental Authority in accordance with applicable law.

            (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by
the Borrower, as promptly as possible thereafter the Borrower shall send to the
Administrative Agent for the account of the Administrative Agent or Lender, as
the case may be, a certified copy of an original official receipt received by
the Borrower showing payment thereof. If the Borrower fails to pay any
Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority
or fails to remit to the Administrative Agent the required receipts or other
required documentary evidence, the Borrower shall indemnify the Administrative
Agent and the Lenders for any incremental taxes, interest or penalties that may
become payable by any Agent or any Lender as a

<PAGE>
                                       40


result of any such failure. The agreements in this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

            (d) Each Lender (or Transferee) that is not U.S. person as defined
in Section 7701(a)(30) of the Code (a "Non-U.S. Lender") shall deliver to the
Borrower and the Administrative Agent (or, in the case of a Participant, to the
Lender from which the related participation shall have been purchased) two
copies of either U.S. Internal Revenue Service Form W-8 BEN or Form W-8 ECI, or,
in the case of a Non-U.S. Lender claiming exemption from U.S. federal
withholding tax under Section 871(h) or 881(c) of the Code with respect to
payments of "portfolio interest" a statement substantially in the form of
Exhibit G and a Form W-8 BEN, or any subsequent versions thereof or successors
thereto properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on
all payments by the Borrower under this Agreement and the other Credit
Documents. Such forms shall be delivered by each Non-U.S. Lender on or before
the date it becomes a party to this Agreement (or, in the case of any
Participant, on or before the date such Participant purchases the related
participation). In addition, each Non-U.S. Lender shall deliver such forms
promptly upon the obsolescence or invalidity of any form previously delivered by
such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at
any time it determines that it is no longer in a position to provide any
previously delivered certificate to the Borrower (or any other form of
certification adopted by the U.S. taxing authorities for such purpose).
Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall
not be required to deliver any form pursuant to this paragraph that such
Non-U.S. Lender is not legally able to deliver.

            (e) A Lender that is entitled to an exemption from or reduction of
non-U.S. withholding tax, with respect to payments under this Agreement shall
deliver to the Borrower (with a copy to the Administrative Agent), at the time
or times reasonably requested by the Borrower, such properly completed and
executed documentation prescribed by applicable law as will permit such payments
to be made without withholding or at a reduced rate; provided that such Lender
is legally entitled to complete, execute and deliver such documentation and in
such Lender's reasonable judgment such completion, execution or submission would
not materially prejudice the legal position of such Lender.

            2.21 Indemnity. The Borrower agrees to indemnify each Lender and to
hold each Lender harmless from any loss or expense which such Lender may sustain
or incur as a consequence of (a) default by the Borrower in making a borrowing
of, conversion into or continuation of Eurodollar Loans after the Borrower has
given a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by the Borrower in making any prepayment after the
Borrower has given a notice thereof in accordance with the provisions of this
Agreement or (c) the making of a prepayment or conversion of Eurodollar Loans on
a day which is not the last day of an Interest Period with respect thereto. Such
indemnification may include an amount equal to the excess, if any, of (i) the
amount of interest which would have accrued on the amount so prepaid, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest

<PAGE>
                                       41


Period that would have commenced on the date of such failure) in each case at
the applicable rate of interest for such Loans provided for herein (excluding,
however, the Applicable Margin included therein, if any) over (ii) the amount of
interest (as reasonably determined by such Lender) which would have accrued to
such Lender on such amount by placing such amount on deposit for a comparable
period with leading banks in the interbank eurodollar market. A certificate as
to any amounts payable pursuant to this Section submitted to the Borrower by any
Lender shall be conclusive in the absence of manifest error. This covenant shall
survive the termination of this Agreement and the payment of the Loans and all
other amounts payable hereunder.

            2.22 Illegality. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Base Rate Loans to Eurodollar Loans shall forthwith be cancelled and (b)
such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be
converted automatically to Base Rate Loans on the respective last days of the
then current Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto, the Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to Section 2.21.

            2.23 Change of Lending Office. Each Lender agrees that, upon the
occurrence of any event giving rise to the operation of Section 2.19, 2.20(a) or
2.22 with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided that such
designation is made on terms that, in the sole judgment of such Lender, cause
such Lender and its lending office(s) to suffer no economic, legal or regulatory
disadvantage, and provided, further, that nothing in this Section shall affect
or postpone any of the obligations of any Borrower or the rights of any Lender
pursuant to Section 2.19, 2.20(a) or 2.22.

            2.24 Replacement of Lenders under Certain Circumstances. The

Requirement of Law, (ii) no Event of Default shall have occurred and be
continuing at the time of such replacement, (iii) prior to any such replacement,
such Lender shall have taken no action under Section 2.22 so as to eliminate the
continued need for payment of amounts owing pursuant to Section 2.19 or 2.20,
(iv) the replacement financial institution shall purchase, at par, all Loans and
other amounts owing to such replaced Lender on or prior to the date of
replacement, (v) the Borrower shall be liable to such replaced Lender under

                    SECTION 3. REPRESENTATIONS AND WARRANTIES

            To induce the Agents and the Lenders to enter into this Agreement
and to make the Loans, the Company and the Borrower hereby jointly and severally
represent and warrant to each Agent and each Lender that:

            3.1 Financial Condition. (a) The audited consolidated balance sheets
of the Company and its consolidated Subsidiaries as at December 31, 1998 and
December 31, 1997 and the related consolidated statements of income and of cash
flows for the fiscal years ended on such dates, reported on by and accompanied
by an unqualified report from Ernst & Young LLP present fairly the consolidated
financial condition of the Company and its consolidated Subsidiaries as at each
such date, and the consolidated results of its operations and its consolidated
cash flows for the respective fiscal years then ended. The unaudited
consolidated balance sheets of the Company and its consolidated Subsidiaries as
at September 30, 1999, and the related unaudited consolidated statements of
income and cash flows for the nine-month period ended on such date, present
fairly the consolidated financial condition of the Company and its consolidated
Subsidiaries as at each such date, and the consolidated results of its
operations and its consolidated cash flows for the three-month period then ended
(subject to normal year-end audit adjustments). All such financial statements,
including the related schedules and notes thereto, have been prepared in
accordance with GAAP applied consistently throughout the periods involved
(except as approved by the aforementioned firm of accountants and disclosed
therein). The Company and its Subsidiaries do not have any material Guarantee
Obligations, contingent liabilities and liabilities for taxes, or any material
long-term leases or unusual forward or long-term commitments, including, without
limitation, any interest rate or foreign currency swap or exchange transaction
or other obligation in respect of derivatives, which are not reflected in the
most recent financial statements referred to in this paragraph or set forth on
Schedule 3.1(a). During the period from December 31, 1998 to and including the
date hereof there has been no Disposition by the Company or any of its
Subsidiaries of any material part of its business or Property.

            (b) The consolidated balance sheet projections, the consolidated
statements of income projections and the consolidated statements of cash flow
projections of the Company and its consolidated Subsidiaries for the 1999
through 2007 fiscal years (the "Projected Financial Statements"), copies of
which have heretofore been furnished to each Lender requesting the same, have
been prepared giving effect (as if such events had occurred on September 30,
1999) to (i) the Loans to be made on the Original Closing Date and the use of
proceeds thereof, (ii) the

<PAGE>
                                       43


payment of fees and expenses in connection with the
foregoing and (iii) the purchase of equity of the Company contemplated by
Preferred Stock Purchase Agreement.

            3.2 No Change. Since December 31, 1998 there has been no development
or event which has had or would have a Material Adverse Effect.

            3.3 Corporate Existence; Compliance with Law. The Company and its
each of Subsidiaries (a) is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, (b) has the
corporate power and authority, and the legal right, to own and operate its
Property, to lease the Property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of Property or the conduct of its business
requires such qualification and (d) is in compliance with all Requirements of
Law (including, without limitation, the obtaining and maintaining all
authorizations, licenses and permits from any Governmental Authority that are
required or necessary for the conduct of the business of the Company and its
Subsidiaries), except, in the case of clauses (c) and (d), to the extent that
the failure to be so qualified or to comply therewith would not, in the
aggregate, reasonably be expected to have a Material Adverse Effect.

            3.4 Corporate Power; Authorization; Enforceable Obligations. Each
Credit Party has the corporate power and authority, and the legal right, to
make, deliver and perform the Credit Documents to which it is a party and, in
the case of the Borrower, to borrow hereunder. Each Credit Party has taken all
necessary corporate action to authorize the execution, delivery and performance
of the Credit Documents to which it is a party and, in the case of the Borrower,
to authorize the borrowings on the terms and conditions of this Agreement. No
consent or authorization of, filing with, notice to or other act by or in
respect of, any Governmental Authority or any other Person is required in
connection with the borrowings hereunder or with the execution, delivery,
performance, validity or enforceability of this Agreement or any of the Credit
Documents, except (i) consents, authorizations, filings and notices described in
Schedule 3.4, which consents, authorizations, filings and notices have been
obtained or made and are in full force and effect and (ii) the filings referred
to in Section 3.18. Each Credit Document has been duly executed and delivered on
behalf of each Credit Party party thereto. This Agreement constitutes, and each
other Credit Document upon execution will constitute, a legal, valid and binding
obligation of each Credit Party party thereto, enforceable against each such
Credit Party in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights generally and by
general equitable principles (whether enforcement is sought by proceedings in
equity or at law).

            3.5 No Legal Bar. The execution, delivery and performance of this
Agreement and the other Credit Documents, the borrowings hereunder and the use
of the proceeds thereof will not violate any Requirement of Law or any
Contractual Obligation of the Company or any of its Subsidiaries and will not
result in, or require, the creation or imposition of any Lien on any of their
respective properties or revenues pursuant to any Requirement of Law or any such
Contractual Obligation (other than the Liens created by the Security Documents).
As of the

<PAGE>
                                       44


Closing Date, no Requirement of Law or Contractual Obligation applicable to the
Company or any of its Subsidiaries would reasonably be expected to have a
Material Adverse Effect.

            3.6 No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Company or the Borrower, threatened by or against the
Company or any of its Subsidiaries or against any of their respective properties
or revenues (a) with respect to any of the Credit Documents or any of the
transactions contemplated hereby or thereby or (b) that would reasonably be
expected, individually or in the aggregate, to have a Material Adverse Effect.

            3.7 No Default. No Default or Event of Default has occurred and is
continuing.

            3.8 Ownership of Property; Liens. Each of the Company and its
Subsidiaries has title in fee simple to, or a valid leasehold interest in, all
its real property, and good title to, or a valid leasehold interest in, all its
other Property, and none of such Property is subject to any Lien except as
permitted by Section 6.3, except for such defects in title which, individually
or in the aggregate, would not reasonably be expected to have a Material Adverse
Effect.

            3.9 Intellectual Property. Each of the Company and its Subsidiaries
owns, or is licensed to use, all Intellectual Property necessary for the conduct
of its business as currently conducted. No material claim has been asserted and
is pending by any Person challenging or questioning the use of any Intellectual
Property or the validity or effectiveness of any Intellectual Property, nor does
the Company or the Borrower know of any valid basis for any such claim. The use
of Intellectual Property by the Company and its Subsidiaries does not infringe
on the rights of any Person in any material respect.

            3.10 Taxes. Each of the Company and its Subsidiaries has filed or
caused to be filed all Federal, state and other material tax returns which are
required to be filed and has paid all taxes shown to be due and payable on said
returns or on any assessments made against it or any of its Property and all
other taxes, fees or other charges imposed on it or any of its Property by any
Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which any reserves necessary in accordance with GAAP have been
provided on the books of the Company or its Subsidiaries, as the case may be);
no material tax Lien has been filed, and, to the knowledge of the Company and
the Borrower, no material claim is being asserted, with respect to any such tax,
fee or other charge.

            3.11 Federal Regulations. No part of the proceeds of any Loans will
be used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U as now and from time to
time hereafter in effect or for any purpose which violates the provisions of the
Regulations of the Board.

            3.12 ERISA. During the five-year period prior to the date on which
this representation is made or deemed made with respect to any Plan, except as
would not reasonably be expected to have a Material Adverse Effect, (i) none of
(x) a Reportable Event, (y) an

<PAGE>
                                       45


"accumulated funding deficiency" (within the meaning of Section 412 of the Code
or Section 302 of ERISA) or (z) a termination of a Single-Employer Plan has
occurred, (ii) each Plan has complied in all material respects with the
applicable provisions of ERISA and the Code and (iii) no Lien in favor of the
PBGC or a Plan has arisen. The present value of all accrued benefits under each
Single Employer Plan (based on those assumptions used to fund such Plans) did
not, as of the last annual valuation date prior to the date on which this
representation is made or deemed made, exceed the value of the assets of such
Plan allocable to such accrued benefits by an amount that would not reasonably
be expected to have a Material Adverse Effect. Neither the Company nor any
Commonly Controlled Entity has had a complete or partial withdrawal from any
Multiemployer Plan which has resulted or would reasonably be expected to result
in a material liability under ERISA, and neither the Company nor any Commonly
Controlled Entity would become subject to any liability under ERISA that would
reasonably be expected to have a Material Adverse Effect if the Company or any
such Commonly Controlled Entity were to withdraw completely from all
Multiemployer Plans as of the valuation date most closely preceding the date on
which this representation is made or deemed made. No such Multiemployer Plan is
in Reorganization or Insolvent.

            3.13 Investment Company Act; Public Utility Holding Company Act;
Other Regulations. No Credit Party is (a) an "investment company" as defined in,
or subject to regulation under, the Investment Company Act of 1940, as amended
or (b) a "holding company" as defined in, or subject to regulation under, the
Public Utility Holding Company Act of 1935, as amended.

            3.14 Capitalization; Subsidiaries; Certain Investments. (a) As of
the Closing Date, (i) Part A of Schedule 3.14 sets forth a complete and correct
list of the authorized Capital Stock of the Company, together with the number of
such shares that are duly and validly issued and outstanding, and each of which
shares is fully paid and nonassessable and (ii) Part B of Schedule 3.14 contains
a complete and correct list of each of record and beneficial owner of issued and
outstanding Capital Stock of the Company, together with, for each such owner,
the percentage of such Capital Stock owned by them.

            (b) Set forth on Part C of Schedule 3.14 is a complete and correct
list of all of the direct and indirect Subsidiaries of the Company as of the
Closing Date, together with, for each such Subsidiary, the jurisdiction of

Capital Stock owned by any Credit Party.

            (c) Set forth on Part D of Schedule 3.14 is a complete and correct
list of all Investments (other than Investments disclosed in Part C of Schedule

Person as of the Closing Date, together with, for each such Investment, the
identity of the Person or Persons holding such Investment and the nature of such

equipment, inventory and/or network assets and back office systems for the
business of the Subsidiaries of the Company and for purposes reasonably related
thereto. The proceeds of the Revolving Extensions of Credit shall be used to
finance the general corporate purposes of the Subsidiaries of the Company.

            3.16 Environmental Matters. Other than exceptions to any of the
following that would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect:

            (a) The Company and its Subsidiaries: (i) are, and at all times have
      been, in compliance with all applicable Environmental Laws; (ii) hold all
      Environmental Permits (each of which is in full force and effect) required
      for any of their current or intended operations or for any property owned,
      leased, or otherwise operated by any of them; (iii) are, and at all times
      have been, in compliance with all of their Environmental Permits; and (iv)
      reasonably believe that: each of their Environmental Permits will be
      timely renewed and complied with, without material expense; any additional
      Environmental Permits that may be required of any of them will be timely
      obtained and complied with, without material expense; and compliance with
      any Environmental Law that is or is expected to become applicable to any

      under, in, or about any real property now or formerly owned, leased or

      location (including, without limitation, any location to which Materials
      of Environmental Concern have been sent for re-use or recycling or for
      treatment, storage, or disposal) which would reasonably be expected to (i)
      give rise to liability of the Company or any of its Subsidiaries under any
      applicable Environmental Law or otherwise result in costs to the Company
      or any of its Subsidiaries, or (ii) interfere with the Company's or any of
      its Subsidiaries' continued operations, or (iii) impair the fair saleable
      value of any real property owned or leased by the Company or any of its
      Subsidiaries.

            (c) There is no judicial, administrative, or arbitral proceeding
      (including any notice of violation or alleged violation) under or relating
      to any Environmental Law to which the Company or any of its Subsidiaries
      is, or to the knowledge of the Company or any of its Subsidiaries will be,
      named as a party that is pending or, to the knowledge of the Company or
      any of its Subsidiaries, threatened.

            (d) Neither the Company nor any of its Subsidiaries has received any
      written request for information, or been notified that it is a potentially
      responsible party under or relating to the federal Comprehensive

<PAGE>
                                       47


            (e) Neither the Company nor any of its Subsidiaries has entered into
      or agreed to any consent decree, order, or settlement or other agreement,

      relating to compliance with or liability under any Environmental Law.

            (f) Neither the Company nor any of its Subsidiaries has assumed or
      retained, by contract or operation of law, any liabilities of any kind,
      fixed or contingent, known or unknown, under any Environmental Law,
      relating to noncompliance with any Environmental Law or with respect to
      any Material of Environmental Concern.

            3.17 Accuracy of Information, etc. No statement or information
contained in this Agreement, any other Credit Document or any other document,
certificate or written statement (including, without limitation, the
Confidential Offering Memorandum) furnished to the Administrative Agent or the
Lenders or any of them, by or on behalf of any Credit Party for use in
connection with the transactions contemplated by this Agreement or the other
Credit Documents, contained, as of the date such statement, information,
document or certificate was so furnished and when taken as a whole with other
such statements and information theretofore so furnished, any untrue statement
of a material fact or omitted to state a material fact necessary in order to
make the statements contained herein or therein not misleading. The projections
and pro forma financial information contained in the materials referenced above
(including, without limitation, the Projected Financial Statements) are based
upon good faith estimates and assumptions believed by management of the Company
to be reasonable at the time made, it being recognized by the Lenders that such
financial information as it relates to future events is not to be viewed as fact
and that actual results during the period or periods covered by such financial
information may differ from the projected results set forth therein by a
material amount. There is no fact known to any Credit Party that would
reasonably be expected to have a Material Adverse Effect that has not been
expressly disclosed herein, in the other Credit Documents, in the Confidential
Information Memorandum or in any other documents, certificates and statements
furnished to the Administrative Agent and the Lenders for use in connection with
the transactions contemplated hereby and by the other Credit Documents.

            3.18 Security Documents. The Guarantee and Collateral Agreement is
effective to create in favor of the Administrative Agent, for the benefit of the
Lenders, a legal, valid and enforceable security interest in the Collateral
described therein and proceeds thereof. In the case of the Pledged Stock covered
by the Guarantee and Collateral Agreement, when any stock certificate
representing such Pledged Stock is delivered to the Administrative Agent, and in
the case of the other Collateral described in the Guarantee and Collateral
Agreement, when financing statements in appropriate form are filed in the
offices specified on Schedule 3.18 (which financing statements have been duly
completed and executed and delivered to the Administrative Agent) and such other
filings as are specified on applicable Schedules, if any, to the Guarantee and
Collateral Agreement (all of which filings have been duly completed), the
Guarantee and Collateral Agreement shall constitute a fully perfected Lien on,
and security interest in, all right, title and interest of the Credit Parties in
such Collateral and the proceeds thereof, as security for the Obligations (as
defined in the Guarantee and Collateral Agreement), prior and superior in

<PAGE>
                                       48


right to any other Person (except, in the case of Collateral other than Pledged
Stock, Liens permitted by Section 6.3).

            3.19 Solvency. On the Closing Date, assuming that Indebtedness in an
amount equal to the aggregate amount of the Commitments is incurred hereunder on
such date, the Company will be Solvent.

            3.20 Real Property. Set forth on Schedule 3.20 is complete and
correct list, as of the Closing Date, of all of the real property interests held
by the Company and its Subsidiaries, indicating in each case whether the
respective property is owned or leased, the identity of the owner or lessee and
the location of the respective property.

            3.21 Year 2000 Matters. Any reprogramming required to permit the
proper functioning, in and following the year 2000, of (i) the Company's and its
Subsidiaries' computer systems and (ii) equipment containing embedded microchips
(including systems and equipment supplied by others or with which Company's or
any of its Subsidiaries' systems interface) and the testing of all such systems
and equipment, as so reprogrammed, has been completed in all material respects.
The cost to the Company or its Subsidiaries of the reasonably foreseeable
consequences of year 2000 to the Company and its Subsidiaries (including,
without limitation, reprogramming errors and the failure of others' systems or
equipment) would not reasonably be expected to result in a Default or a Material
Adverse Effect. The computer and management information systems of the Company
and its Subsidiaries are and, with ordinary course upgrading and maintenance,
will continue for the term of this Agreement to be, sufficient to permit the
Company and its Subsidiaries to conduct their respective business, other than
any insufficiency that would not reasonably be expected to have a Material
Adverse Effect.

            3.22 Restricted Subsidiary. Each of the Borrower and each Subsidiary
Guarantor is, and at all times shall remain, a "Restricted Subsidiary" under and
as defined in the Existing Senior Notes Indenture.

            3.23 Network. Schedule 3.23 sets forth, as of the Closing Date, (i)
the location of each switch owned by the Company or any of its Subsidiaries and
the switch's make and model and (ii) the location of each Collocation Site. As
of the Closing Date, the Company's and its Subsidiaries' switches are (i) fully
installed, (ii) interconnected to the incumbent telephone company's local
network and (iii) capable of commercial traffic. As of the Closing Date, each
Collocation Site possesses all the necessary equipment to carry commercial
traffic and is linked via leased or owned transmission cable to a switch owned
by the Company or one of its Subsidiaries.

automatically the Commitments shall immediately terminate and the Loans
hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Credit Documents shall immediately become due and

hereunder (with accrued interest thereon) and all other amounts owing under this
Agreement and the other Credit Documents to be due and payable forthwith,
whereupon the same shall immediately become due and payable.

                              SECTION 8. THE AGENTS

            8.1 Appointment. Each Lender hereby irrevocably designates and
appoints the Agents as the agents of such Lender under this Agreement and the
other Credit Documents, and each such Lender irrevocably authorizes each Agent,
in such capacity, to take such action on its behalf under the provisions of this
Agreement and the other Credit Documents and to exercise such powers and perform
such duties as are expressly delegated to the such Agent by the terms of this
Agreement and the other Credit Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
elsewhere in this Agreement, no Agent shall have any duties or responsibilities,
except those expressly set forth herein, or any fiduciary relationship with any
Lender, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Credit
Document or otherwise exist against any Agent.

            8.2 Delegation of Duties. Each Agent may execute any of its duties
under this Agreement and the other Credit Documents by or through agents or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. No Agent shall be responsible for the
negligence or misconduct of any agents or attorneys in-fact selected by it with
reasonable care.

            8.3 Exculpatory Provisions. Neither any Agent nor any of their
respective officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Credit Document (except to the extent that any of the foregoing are found
by a final and nonappealable decision of a court of competent jurisdiction to
have resulted from its or such Person's own gross negligence or willful
misconduct) or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by any Credit Party or
any officer thereof contained in this Agreement or any other Credit Document or
in any certificate, report, statement or other document referred to or provided
for in, or received by the Agents under or in connection with, this Agreement or
any other Credit Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Credit
Document or for any failure of any Credit Party a party thereto to perform its
obligations hereunder or thereunder. The Agents shall not be under any
obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Credit Document, or to inspect the properties, books or
records of any Credit Party.

            8.4 Reliance by Agents. Each Agent shall be entitled to rely, and
shall be fully protected in relying, upon any instrument, writing, resolution,
notice, consent, certificate, affidavit, letter, telecopy, telex or teletype
message, statement, order or other document or conversation believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without
limitation, counsel to any of the Credit Parties), independent accountants and
other experts selected by the Administrative Agent. The Agents may deem and
treat the payee of any Note as the owner thereof for all purposes unless a
written notice of assignment, negotiation or transfer

<PAGE>
                                       74


thereof shall have been filed with the Administrative Agent. Each Agent shall be
fully justified in failing or refusing to take any action under this Agreement
or any other Credit Document unless it shall first receive such advice or
concurrence of the Required Lenders (or, if so specified by this Agreement, all
Lenders) as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action.
Each Agent shall in all cases be fully protected in acting, or in refraining
from acting, under this Agreement and the other Credit Documents in accordance
with a request of the Required Lenders (or, if so specified by this Agreement,
all Lenders), and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Lenders and all future holders of the
Loans.

            8.5 Notice of Default. No Agent shall be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless
such Agent has received notice from a Lender, the Company or the Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". In the event that the
Administrative Agent receives such a notice, the Administrative Agent shall give
notice thereof to the Lenders. The Administrative Agent shall take such action
with respect to such Default or Event of Default as shall be reasonably directed
by the Required Lenders (or, if so specified by this Agreement, all Lenders);
provided that unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take
such action, or refrain from taking such action, with respect to such Default or
Event of Default as it shall deem advisable in the best interests of the
Lenders.

            8.6 Non-Reliance on Agents and Other Lenders. Each Lender expressly
acknowledges that neither the Agents nor any of their respective officers,
directors, employees, agents, attorneys-in-fact or affiliates have made any
representations or warranties to it and that no act by any Agent hereinafter
taken, including any review of the affairs of a Credit Party or any affiliate of
a Credit Party, shall be deemed to constitute any representation or warranty by
any Agent to any Lender. Each Lender represents to the Agents that it has,
independently and without reliance upon any Agent or any other Lender, and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Credit Parties and
their affiliates and made its own decision to make its Loans hereunder and enter
into this Agreement. Each Lender also represents that it will, independently and
without reliance upon any Agent or any other Lender, and based on such documents
and information as it shall deem appropriate at the time, continue to make its
own credit analysis, appraisals and decisions in taking or not taking action
under this Agreement and the other Credit Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Credit Parties and their affiliates. Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, no Agent shall have any duty or responsibility
to provide any Lender with any credit or other information concerning the
business, operations, property, condition (financial or otherwise), prospects or
creditworthiness of any Credit Party or any affiliate of a Credit Party which
may come into the possession of such Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates.

<PAGE>
                                       75


            8.7 Indemnification. The Lenders agree to indemnify each Agent in
its capacity as such (to the extent not reimbursed by the Company or the
Borrower and without limiting the obligation of the Company or the Borrower to
do so), ratably according to their respective Aggregate Exposure Percentages in
effect on the date on which indemnification is sought under this Section (or, if
indemnification is sought after the date upon which the Commitments shall have
terminated and the Loans shall have been paid in full, ratably in accordance
with such Aggregate Exposure Percentages immediately prior to such date), from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever which may at any time (including, without limitation, at any time
following the payment of the Loans) be imposed on, incurred by or asserted
against such Agent in any way relating to or arising out of, the Commitments,
this Agreement, any of the other Credit Documents or any documents contemplated
by or referred to herein or therein or the transactions contemplated hereby or
thereby or any action taken or omitted by such Agent under or in connection with
any of the foregoing; provided that no Lender shall be liable for the payment of
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements which are found by a
final and nonappealable decision of a court of competent jurisdiction to have
resulted from such Agent's gross negligence or willful misconduct. The
agreements in this Section shall survive the payment of the Loans and all other
amounts payable hereunder.

            8.8 Agent in Its Individual Capacity. Each Agent and its affiliates
may make loans to, accept deposits from and generally engage in any kind of
business with any Credit Party as though such Agent was not an Agent. With
respect to its Loans made or renewed by it, each Agent shall have the same
rights and powers under this Agreement and the other Credit Documents as any
Lender and may exercise the same as though it were not an Agent, and the terms
"Lender" and "Lenders" shall include each Agent in its individual capacity.

            8.9 Successor Agents. The Administrative Agent may resign as
Administrative Agent upon 10 days' notice to the Lenders and the Borrower. If
the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Credit Documents, then the Required Lenders shall
appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall (unless an Event of Default under Section 7(a) or Section
7(f) with respect to the Borrower shall have occurred and be continuing) be
subject to approval by the Borrower (which approval shall not be unreasonably
withheld or delayed), whereupon such successor agent shall succeed to the
rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Loans. If no successor agent
has accepted appointment as Administrative Agent by the date that is 10 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become
effective, and the Lenders shall assume and perform all of the duties of the
Administrative Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above.

<PAGE>
                                       76


After the retiring Administrative Agent's resignation as Administrative Agent,
the provisions of this Section 8 shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Credit Documents.

            8.10 Authorization to Release Liens. The Administrative Agent is
hereby irrevocably authorized by each of the Lenders to release any Lien
covering any Property of the Borrower or any of its Subsidiaries that is the
subject of a Disposition which is permitted by this Agreement or which has been
consented to in accordance with Section 9.1.

            8.11 The Arranger, Documentation Agent and Syndication Agent. The
Arranger, the Documentation Agent and the Syndication Agent listed on the cover
page hereof shall have no duties or responsibilities, and shall incur no
liability, under this Agreement and the other Credit Documents, except in their
capacity, if any, as Lenders hereunder.

                            SECTION 9. MISCELLANEOUS

            9.1 Amendments and Waivers. Neither this Agreement or any other
Credit Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section. The Required
Lenders and each Credit Party party to the relevant Credit Document may, or
(with the written consent of the Required Lenders) the Administrative Agent and
each Credit Party party to the relevant Credit Document may, from time to time,
(a) enter into written amendments, supplements or modifications hereto and to
the other Credit Documents (including amendments and restatements hereof or
thereof) for the purpose of adding any provisions to this Agreement or the other
Credit Documents or changing in any manner the rights of the Lenders or of the
Credit Parties hereunder or thereunder or (b) waive, on such terms and
conditions as may be specified in the instrument of waiver, any of the
requirements of this Agreement or the other Credit Documents or any Default or
Event of Default and its consequences; provided, however, that no such waiver
and no such amendment, supplement or modification shall (i) forgive the
principal amount or extend the final scheduled date of maturity of any Loan,
extend the scheduled date of any amortization payment in respect of any Loan,
reduce the stated rate of any interest or fee payable hereunder or extend the
scheduled date of any payment thereof, in each case without the consent of each
Lender directly and adversely affected thereby, or increase the amount or extend
the expiration date of any Commitment of any Lender, without the consent of such
Lender; (ii) amend, modify or waive any provision of this Section or reduce any
percentage specified in the definition of Required Lenders, or consent to the
assignment or transfer by the Company or the Borrower of any of its rights and
obligations under this Agreement and the other Credit Documents, in each case
without the consent of all Lenders; (iii) release all or substantially all of
the Collateral or release all or substantially all of the Guarantors from their
guarantee obligations under the Credit Documents (except as otherwise expressly
permitted under the Credit Documents), in each case without the consent of all
Lenders; (iv) reduce the percentage specified in the definition of Majority
Facility Lenders with respect to any Facility without the written consent of all
Lenders under such Facility; (v) amend, modify or waive any provision of Section
8 without the consent of any Agent directly affected thereby; or (vi) amend,
modify or waive any provision of Section 2.6 or 2.7 without the written consent
of the Swing Line Lender.

<PAGE>
                                       77


            Notwithstanding anything to the contrary contained herein or in any
Security Document, upon request of the Borrower, the Administrative Agent shall
(without notice to or vote or consent of any Lender) take action having the
effect of releasing any Collateral and/or guarantee obligations provided for in
such Security Document to the extent necessary to permit consummation, by the
relevant Person in accordance with the terms of this Agreement and the other
Credit Documents, of any transaction not prohibited hereunder. Any waiver and
any amendment, supplement or modification of a type referred to above shall
apply equally to each of the Lenders and shall be binding upon the Credit
Parties, the Lenders, the Administrative Agent and all future holders of the
Loans. In the case of any waiver, the Credit Parties, the Lenders and the
Administrative Agent shall be restored to their former position and rights
hereunder and under the other Credit Documents, and any Default or Event of
Default waived shall be deemed to be cured and not continuing; but no such
waiver shall extend to any subsequent or other Default or Event of Default, or
impair any right consequent thereon. Any such waiver, amendment, supplement or
modification shall be effected by a written instrument signed by the parties
required to sign pursuant to the foregoing provisions of this Section; provided
that delivery of an executed signature page of any such instrument by facsimile
transmission shall be effective as delivery of a manually executed counterpart
thereof.

            9.2 Notices. All notices, requests and demands to or upon the
respective parties hereto to be effective shall be in writing (including by

delay in exercising, on the part of any Agent or any Lender, any right, remedy,
power or privilege hereunder or under the other Credit Documents shall operate

thereof or the exercise of any other right, remedy, power or privilege. The
rights, remedies, powers and privileges herein provided are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

            9.4 Survival of Representations and Warranties. All representations
and warranties made hereunder, in the other Credit Documents and in any
document, certificate or statement delivered pursuant hereto or in connection
herewith shall survive the execution and delivery of this Agreement and the

            9.5 Payment of Expenses. The Borrower agrees (a) to pay or reimburse
the Administrative Agent for all their reasonable out-of-pocket costs and
expenses incurred in connection with the syndication of the Facilities (other
than fees payable to syndicate members) and the development, preparation and
execution of, and any amendment, supplement or modification to, this Agreement
and the other Credit Documents and any other documents prepared in connection
herewith or therewith, and the consummation and administration of the
transactions contemplated hereby and thereby, including, without limitation, the
reasonable fees and disbursements and other charges of counsel to the
Administrative Agent, (b) to pay or reimburse each Lender and the Agents for all
its costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, the other Credit Documents and
any such other documents, including, without limitation, the fees and
disbursements of counsel (including the allocated fees and disbursements and
other charges of in-house counsel) to each Lender and of counsel to the Agents,
(c) to pay, indemnify, and hold each Lender and the Agents harmless from, any
and all recording and filing fees and any and all liabilities with respect to,
or resulting from any delay in paying, stamp, excise and other taxes, if any,
which may be payable or determined to be payable in connection with the
execution and delivery of, or consummation or administration of any of the
transactions contemplated by, or any amendment, supplement or modification of,
or any waiver or consent under or in respect of, this Agreement, the other
Credit Documents and any such other documents, and (d) to pay, indemnify, and
hold each Lender and the Agents and their respective officers, directors,
trustees, employees, affiliates, agents, controlling persons, attorneys and

<PAGE>
                                       79


from and against any and all other liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery, enforcement,
performance and administration of this Agreement, the other Credit Documents and
any such other documents, including, without limitation, any of the foregoing
relating to the use of proceeds of the Loans or the violation of, noncompliance
with or liability under, any Environmental Law applicable to the operations of
the Company or any of its Subsidiaries or any of the Properties and the fees and
disbursements and other charges of legal counsel in connection with claims,
actions or proceedings by any Indemnitee against the Borrower hereunder (all the
foregoing in this clause (d), collectively, the "Indemnified Liabilities");
provided that the Borrower shall have no obligation hereunder to any Indemnitee
with respect to Indemnified Liabilities to the extent such Indemnified
Liabilities are found by a final and nonappealable decision of a court of
competent jurisdiction to have resulted from the gross negligence or willful
misconduct of such Indemnitee. Without limiting the foregoing, and to the extent
permitted by applicable law, the Company agrees not to assert and to cause its
Subsidiaries not to assert, and hereby waives and agrees to cause its
Subsidiaries so to waive, all rights for contribution or any other rights of
recovery with respect to all claims, demands, penalties, fines, liabilities,
settlements, damages, costs and expenses of whatever kind or nature, under or
related to Environmental Laws, that any of them might have by statute or
otherwise against any indemnitee. The agreements in this Section shall survive
repayment of the Loans and all other amounts payable hereunder.

            9.6 Successors and Assigns; Participations and Assignments. (a) This
Agreement shall be binding upon and inure to the benefit of the Company, the
Borrower, the Lenders, the Agents, all future holders of the Loans and their
respective successors and assigns, except that neither the Company nor the
Borrower may assign or transfer any of its respective rights or obligations
under this Agreement without the prior written consent of the Administrative
Agent and each Lender.

            (b) Any Lender may, without the consent of the Borrower, in
accordance with applicable law, at any time sell to one or more banks, financial
institutions or other entities (each, a "Participant") participating interests
in any Loan owing to such Lender, any Commitment of such Lender or any other
interest of such Lender hereunder and under the other Credit Documents. In the
event of any such sale by a Lender of a participating interest to a Participant,
such Lender's obligations under this Agreement to the other parties to this
Agreement shall remain unchanged, such Lender shall remain solely responsible
for the performance thereof, such Lender shall remain the holder of any such
Loan for all purposes under this Agreement and the other Credit Documents, and
the Borrower and the Agents shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement and the other Credit Documents. In no event shall any Participant
under any such participation have any right to approve any amendment or waiver
of any provision of any Credit Document, or any consent to any departure by any
Credit Party therefrom, except for those matters specified in clauses (i), (ii)
and (iii) of the proviso in Section 9.1. The Borrower agrees that if amounts
outstanding under this Agreement and the Loans are due or unpaid, or shall have
been declared or shall have become due and payable upon the occurrence of an
Event of Default, each Participant shall, to the maximum extent permitted by
applicable law, be deemed to have

<PAGE>
                                       80


the right of setoff in respect of its participating interest in amounts owing
under this Agreement to the same extent as if the amount of its participating
interest were owing directly to it as a Lender under this Agreement; provided
that, in purchasing such participating interest, such Participant shall be
deemed to have agreed to share with the Lenders the proceeds thereof as provided
in Section 9.7(a) as fully as if it were a Lender hereunder. The Borrower also
agrees that each Participant shall be entitled to the benefits of Sections 2.19,
2.20 and 2.21 with respect to its participation in the Commitments and the Loans
outstanding from time to time as if it was a Lender; provided that, in the case
of Section 2.20, such Participant shall have complied with the requirements of
Section 2.20 and provided, further, that no Participant shall be entitled to
receive any greater amount pursuant to any such Section than the transferor
Lender would have been entitled to receive in respect of the amount of the
participation transferred by such transferor Lender to such Participant had no
such transfer occurred.

            (c) Any Lender (an "Assignor") may, in accordance with applicable
law and upon written notice to the Administrative Agent, at any time and from
time to time assign to any Lender or any Affiliate thereof or, with the written
consent of the Borrower and the Administrative Agent and, in the case of any
assignment of Revolving Credit Commitments and Revolving Credit Loans only, the
written consent of the Swing Line Lender (which, in each case, shall not be
unreasonably withheld or delayed and shall not be required in connection with an
assignment involving LCPI or any of its Affiliates) to an additional bank,
financial institution or other entity (an "Assignee") all or any part of its
rights and obligations under this Agreement pursuant to an Assignment and
Acceptance, substantially in the form of Exhibit D, executed by such Assignee
and such Assignor (and, where the consent of the Borrower, the Administrative
Agent or the Swing Line Lender is required pursuant to the foregoing provisions,
by the Borrower and such other Persons) and delivered to the Administrative
Agent for its acceptance and recording in the Register; provided that (i) no
such assignment to an Assignee (other than any Lender or any Affiliate thereof,
including, without limitation, in the case of any Lender that is an investment
fund which is regularly engaged in making, purchasing or investing in loans or
securities, any other such fund which is under common (or affiliated) management
with such Lender) shall (other than in the case of an assignment of all of a
Lender's rights under this Agreement) be in an aggregate principal amount of
less than $5,000,000 (or such lesser amount as may be agreed to by the Borrower
and the Administrative Agent) and (ii) each partial assignment of any Class of
Commitment and/or Loans shall be made as an assignment or a proportionate part
of all the assigning Lender's rights and obligations of such Class of
Commitments and Loans under this Agreement. Any such assignment need not be
ratable as among the Facilities. Upon such execution, delivery, acceptance and
recording, from and after the effective date determined pursuant to such
Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto
and, to the extent provided in such Assignment and Acceptance, have the rights
and obligations of a Lender hereunder with a Commitment and/or Loans as set
forth therein, and (y) the Assignor thereunder shall, to the extent provided in
such Assignment and Acceptance, be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all of an
Assignor's rights and obligations under this Agreement, such Assignor shall
cease to be a party hereto). Notwithstanding any provision of this Section, the
consent of the Borrower shall not be required for any assignment which occurs at
any time when any Event of Default shall have occurred and be continuing.

<PAGE>
                                       81


            (d) The Administrative Agent shall, on behalf of the Borrower,
maintain at its address referred to in Section 9.2 a copy of each Assignment and
Acceptance delivered to it and a register (the "Register") for the recordation
of the names and addresses of the Lenders and the Commitment of, and principal
amount of the Loans owing to, each Lender from time to time. The entries in the
Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Administrative Agent and the Lenders shall treat each Person whose
name is recorded in the Register as the owner of the Loans and any Notes
evidencing such Loans recorded therein for all purposes of this Agreement. Any
assignment of any Loan, whether or not evidenced by a Note, shall be effective
only upon appropriate entries with respect thereto being made in the Register
(and each Note shall expressly so provide). Any assignment or transfer of all or
part of a Loan evidenced by a Note shall be registered on the Register only upon
surrender for registration of assignment or transfer of the Note evidencing such
Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or
more new Notes in the same aggregate principal amount shall be issued to the
designated Assignee, and the old Notes shall be returned by the Administrative
Agent to the Borrower marked "cancelled". The Register shall be available for
inspection by the Borrower or any Lender at any reasonable time and from time to
time upon reasonable prior notice.

            (e) Upon its receipt of an Assignment and Acceptance executed by an
Assignor and an Assignee (and, in any case where the consent of any other Person
is required by Section 9.6(c), by each such other Person) together with payment
to the Administrative Agent of a registration and processing fee of $3,500
(except that no such registration and processing fee shall be payable (y) in
connection with an assignment by or to LCPI or any of its Affiliates or (z) in
the case of an Assignee which is already a Lender or is an Affiliate of a Lender
(including, without limitation in the case of any Lender that is an investment
fund which is regularly engaged in making, purchasing or investing in loans or
securities, any other such fund which is under common (or affiliated) management
with such Lender), the Administrative Agent shall (i) promptly accept such
Assignment and Acceptance and (ii) on the effective date determined pursuant
thereto record the information contained therein in the Register and give notice
of such acceptance and recordation to the Lenders and the Borrower. On or prior
to such effective date, the Borrower, at its own expense, upon request, shall
execute and deliver to the Administrative Agent (in exchange for the Revolving
Credit Note and/or Term Note, as the case may be, of the assigning Lender) a new
Revolving Credit Note and/or Term Note, as the case may be, to the order of such
Assignee in an amount equal to the Revolving Credit Commitment and/or Term
Commitment or Term Loans, as the case may be, assumed or acquired by it pursuant
to such Assignment and Acceptance and, if the Assignor has retained a Revolving
Credit Commitment and/or Term Commitment or Term Loans, as the case may be, upon
request, a new Revolving Credit Note and/or Term Notes, as the case may be, to
the order of the Assignor in an amount equal to the Revolving Credit Commitment
and/or applicable Term Commitment or Term Loans, as the case may be, retained by
it hereunder. Such new Note or Notes shall be dated the Closing Date and shall
otherwise be in the form of the Note or Notes replaced thereby.

            (f) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this Section concerning assignments of Loans
and Notes relate only to absolute

<PAGE>
                                       82


assignments and that such provisions do not prohibit assignments creating
security interests, including, without limitation, any pledge or assignment by a
Lender of any Loan or Note to any Person including, without limitation, any
Federal Reserve Bank in accordance with applicable law.

            9.7 Adjustments; Set-off. (a) Except to the extent that this
Agreement provides for payments to be allocated to a particular Lender or to the
Lenders under a particular Facility, if any Lender (a "Benefitted Lender") shall
at any time receive any payment of all or part of the Obligations owing to it,
or receive any collateral in respect thereof (whether voluntarily or
involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in Section 7(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of such other Lender's Obligations, such Benefitted Lender shall purchase for
cash from the other Lenders a participating interest in such portion of each
such other Lender's Obligations, or shall provide such other Lenders with the
benefits of any such collateral, as shall be necessary to cause such Benefitted
Lender to share the excess payment or benefits of such collateral ratably with
each of the Lenders; provided, however, that if all or any portion of such
excess payment or benefits is thereafter recovered from such Benefitted Lender,
such purchase shall be rescinded, and the purchase price and benefits returned,
to the extent of such recovery, but without interest.

            (b) In addition to any rights and remedies of the Lenders provided
by law, each Lender shall have the right, without prior notice to the Company or
the Borrower, any such notice being expressly waived by the Company and the
Borrower to the extent permitted by applicable law, upon any amount becoming due
and payable by the Company or the Borrower hereunder (whether at the stated
maturity, by acceleration or otherwise), to set off and appropriate and apply
against such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by such Lender or
any branch or agency thereof to or for the credit or the account of the Company
or the Borrower, as the case may be. Each Lender agrees promptly to notify the
Borrower and the Administrative Agent after any such setoff and application made
by such Lender; provided that the failure to give such notice shall not affect
the validity of such setoff and application.

            9.8 Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof. A set of the copies of this Agreement signed by all the
parties shall be lodged with the Borrower and the Administrative Agent.

            9.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any

<PAGE>
                                       83


such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

            9.10 Integration. This Agreement and the other Credit Documents
represent the agreement of the Company, the Borrower, the Administrative Agent
and the Lenders with respect to the subject matter hereof, and there are no
promises, undertakings, representations or warranties by the Administrative
Agent or any Lender relative to subject matter hereof not expressly set forth or
referred to herein or in the other Credit Documents.

            9.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

            9.12 Submission to Jurisdiction; Waivers. Each of the Company and
the Borrower hereby irrevocably and unconditionally:

            (a) submits for itself and its Property in any legal action or
      proceeding relating to this Agreement and the other Credit Documents to
      which it is a party, or for recognition and enforcement of any judgment in
      respect thereof, to the non-exclusive general jurisdiction of the courts
      of the State of New York, the courts of the United States of America for
      the Southern District of New York, and appellate courts from any thereof;

            (b) consents that any such action or proceeding may be brought in
      such courts and waives any objection that it may now or hereafter have to
      the venue of any such action or proceeding in any such court or that such
      action or proceeding was brought in an inconvenient court and agrees not
      to plead or claim the same;

            (c) agrees that service of process in any such action or proceeding
      may be effected by mailing a copy thereof by registered or certified mail
      (or any substantially similar form of mail), postage prepaid, to the
      Company or the Borrower, as the case may be, at its address set forth in
      Section 9.2 or at such other address of which the Administrative Agent
      shall have been notified pursuant thereto;

            (d) agrees that nothing herein shall affect the right to effect
      service of process in any other manner permitted by law or shall limit the
      right to sue in any other jurisdiction; and

            (e) waives, to the maximum extent not prohibited by law, any right
      it may have to claim or recover in any legal action or proceeding referred
      to in this Section any special, exemplary, punitive or consequential
      damages.

            9.13 Acknowledgments. Each of the Company and the Borrower hereby
acknowledges that:

<PAGE>
                                       84


            (a) it has been advised by counsel in the negotiation, execution and
      delivery of this Agreement and the other Credit Documents;

            (b) neither the Administrative Agent nor any Lender has any
      fiduciary relationship with or duty to the Company or the Borrower arising
      out of or in connection with this Agreement or any of the other Credit
      Documents, and the relationship between Administrative Agent and Lenders,
      on one hand, and the Company and the Borrower, on the other hand, in
      connection herewith or therewith is solely that of debtor and creditor;
      and

            (c) no joint venture is created hereby or by the other Credit
      Documents or otherwise exists by virtue of the transactions contemplated
      hereby among the Lenders or among the Company, the Borrower and the
      Lenders.

            9.14 Confidentiality. Each of the Agents and the Lenders agrees to
keep confidential all non-public information provided to it by any Credit Party
pursuant to this Agreement that is designated by such Credit Party as
confidential (including any such information already in the possession of such
Lender or provided to such Lender by a third party not in violation of this
Agreement which, in either case, is not, to the knowledge of such Lender,
subject to a confidentiality agreement); provided that nothing herein shall
prevent any Agent or any Lender from disclosing any such information (a) to any
Agent or any other Lender or any of its Affiliates, (b) to any Participant or
Assignee (each, a "Transferee") or prospective Transferee or to any direct or
indirect contractual counterparties in swap agreements or such contractual
counterparties' professional advisors which receives such information and agrees
to comply with the provisions of this Section, (c) any of its employees,
directors, agents, attorneys, accountants and other professional advisors, (d)
upon the request or demand of any Governmental Authority having jurisdiction
over it, (e) in response to any order of any court or other Governmental
Authority or as may otherwise be required pursuant to any Requirement of Law,
(f) if requested or required to do so in connection with any litigation or
similar proceeding, (g) which has been publicly disclosed other than in breach
of this Section, (h) to the National Association of Insurance Commissioners or
any similar organization or any nationally recognized rating agency that
requires access to information about a Lender's investment portfolio in
connection with ratings issued with respect to such Lender or (i) in connection
with the exercise of any remedy hereunder or under any other Credit Document.

            9.15 Accounting Changes. In the event that any "Accounting Changes"
(as defined below) shall occur and such changes result in a change in the method
of calculation of financial covenants, standards or terms in this Agreement,
then the Company, the Borrower and the Administrative Agent agree to enter into
negotiations in order to amend such provisions of this Agreement so as to
equitably reflect such Accounting Changes with the desired result that the
criteria for evaluating the Company's and the Borrower's financial condition
shall be the same after such Accounting Changes as if such Accounting
Changes had not been made. Until such time as such an amendment shall have been
executed and delivered by the Company, the Borrower, the Administrative Agent
and the Required Lenders, all financial covenants, standards and terms in this
Agreement shall continue to be calculated or construed as if such Accounting

<PAGE>
                                       85


Changes had not occurred. "Accounting Changes" refers to changes in accounting
principles required by the promulgation of any rule, regulation, pronouncement
or opinion by the Financial Accounting Standards Board of the American Institute
of Certified Public Accountants or, if applicable, the SEC.

            9.16 Delivery of Lender Addenda. Each initial Lender shall become a
party to this Agreement by delivering to the Administrative Agent a Lender
Addendum duly executed by such Lender, the Borrower and the Administrative
Agent.

ADMINISTRATIVE AGENT AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY

OR ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

unconditionally and irrevocably, guarantees to the Administrative Agent, for the

            (c) Each Guarantor agrees that the Borrower Obligations may at any
time and from time to time exceed the amount of the liability of such Guarantor

affecting the rights and remedies of the Administrative Agent or any Lender

            (d) The guarantee contained in this Section 2 shall remain in full
force and effect until all the Borrower Obligations and the obligations of each
Guarantor under the guarantee contained in this Section 2 shall have been
satisfied by payment in full, no Letter of Credit shall be outstanding and the
Commitments shall be terminated, notwithstanding that from time to time during
the term of the Credit Agreement the Borrower may be free from any Borrower
Obligations.

            (e) No payment made by the Borrower, any of the Guarantors, any

made by such Guarantor in respect of the Borrower Obligations or any payment
received or collected from such Guarantor in respect of the Borrower

guarantee or right of offset held by the Administrative Agent or any Lender for
the payment of the Borrower Obligations, nor shall any Guarantor seek or be

other Guarantor in respect of payments made by such Guarantor hereunder, until
all amounts owing to the Administrative Agent and the Lenders by the Borrower on
account of the Borrower Obligations are paid in full, no Letter of Credit shall
be outstanding and the Commitments are terminated. If any amount shall be paid
to any Guarantor on account of such subrogation rights at any time when all of
the Borrower Obligations shall not have been paid in full, such amount shall be
held by such Guarantor in trust for the Administrative Agent and the Lenders,
segregated from other funds of such Guarantor, and shall, forthwith upon receipt
by such Guarantor, be turned over to the Administrative Agent in the exact form
received by such Guarantor (duly indorsed by such Guarantor to the
Administrative Agent, if required), to be applied against the Borrower
Obligations, whether matured or unmatured, in such order as the Administrative
Agent may determine.

            2.4 Amendments, etc. with respect to the Borrower Obligations.
Each Guarantor shall remain obligated hereunder notwithstanding that, without

assent by any Guarantor, any demand for payment of any of the Borrower
Obligations made by the Administrative Agent or any Lender may be rescinded by
the Administrative Agent or such Lender and any of the Borrower Obligations
continued, and the Borrower Obligations, or the liability of any other Person
upon or for any part thereof, or any collateral security or guarantee therefor
or right of offset with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Administrative Agent or any Lender, and the
Credit Agreement and the other Credit Documents and any other documents executed
and delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Administrative Agent (or the Required
Lenders or all Lenders, as the case may be) may deem advisable from time to
time, and any collateral security, guarantee or right of offset at any time held
by the Administrative Agent or any Lender for the payment of the Borrower
Obligations may be sold, exchanged, waived, surrendered or released. Neither the
Administrative Agent nor any Lender shall have any obligation to protect,
secure, perfect or insure any Lien at any time held by it as security for the
Borrower Obligations or for the guarantee contained in this Section 2 or any
property subject thereto.

            2.5 Guarantee Absolute and Unconditional. Each Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Borrower Obligations and notice of or proof of reliance by the Administrative
Agent or any Lender upon the guarantee contained in this Section 2 or acceptance
of the guarantee contained in this Section 2; the Borrower Obligations, and any
of them, shall conclusively be deemed to have been created, contracted or
incurred, or renewed, extended, amended or waived, in reliance upon the
guarantee contained in this Section 2; and all dealings between the Borrower and
any of the Guarantors, on the one hand, and the Administrative Agent and the
Lenders, on the other hand, likewise shall be conclusively presumed to have been
had or consummated in reliance upon the guarantee contained in this Section 2.
Each Guarantor waives diligence, presentment, protest,

demand for payment and notice of default or nonpayment to or upon the Borrower
or any of the Guarantors with respect to the Borrower Obligations. Each
Guarantor understands and agrees that the guarantee contained in this Section 2
shall be construed as a continuing, absolute and unconditional guarantee of
payment without regard to (a) the validity or enforceability of the Credit
Agreement or any other Credit Document, any of the Borrower Obligations or any
other collateral security therefor or guarantee or right of offset with respect
thereto at any time or from time to time held by the Administrative Agent or any
Lender, (b) any defense, set-off or counterclaim (other than a defense of
payment or performance) which may at any time be available to or be asserted by
the Borrower or any other Person against the Administrative Agent or any Lender,
or (c) any other circumstance whatsoever (with or without notice to or knowledge
of the Borrower or such Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Borrower for the Borrower
Obligations, or of such Guarantor under the guarantee contained in this Section
2, in bankruptcy or in any other instance. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against any Guarantor, the
Administrative Agent or any Lender may, but shall be under no obligation to,
make a similar demand on or otherwise pursue such rights and remedies as it may
have against the Borrower, any other Guarantor or any other Person or against
any collateral security or guarantee for the Borrower Obligations or any right
of offset with respect thereto, and any failure by and Agent or any Lender to
make any such demand, to pursue such other rights or remedies or to collect any
payments from the Borrower, any other Guarantor or any other Person or to
realize upon any such collateral security or guarantee or to exercise any such
right of offset, or any release of the Borrower, any other Guarantor or any
other Person or any such collateral security, guarantee or right of offset,
shall not relieve any Guarantor of any obligation or liability hereunder, and
shall not impair or affect the rights and remedies, whether express, implied or
available as a matter of law, of any Agent or any Lender against any Guarantor.
For the purposes hereof "demand" shall include the commencement and continuance
of any legal proceedings.

            2.6 Reinstatement. The guarantee contained in this Section 2 shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Borrower Obligations is rescinded or
must otherwise be restored or returned by the Administrative Agent or any Lender
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of
the Borrower or any Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, the
Borrower or any Guarantor or any substantial part of its property, or otherwise,
all as though such payments had not been made.

            2.7 Payments. Each Guarantor hereby guarantees that payments
hereunder will be paid to the Administrative Agent without set-off or
counterclaim in Dollars at the office of the Administrative Agent located at the
Payment Office specified in the Credit Agreement.

            (a) At any time an Event of Default has occurred and is
continuing, the Administrative Agent shall have the right to make test
verifications of the Receivables in any manner and through any medium that it
reasonably considers advisable, and each Grantor shall furnish all such
assistance and information as the Administrative Agent may require in connection
with such test verifications. At any time an Event of Default has occurred and

relevant Grantor, such Grantor shall cause independent public accountants or
others satisfactory to the Administrative Agent to furnish to the Administrative
Agent reports showing reconciliations, aging and test verifications of, and

            (b) The Administrative Agent hereby authorizes each Grantor to
collect such Grantor's Receivables, subject to the Administrative Agent's
direction and control at any time an Event of Default has occurred and is
continuing, and the Administrative Agent may curtail or terminate said authority
at any time after the occurrence and during the continuance of an Event of
Default. If required by the Administrative Agent at any time after the
occurrence and during the continuance of an Event of Default, any payments of
Receivables, when collected by any Grantor, (i) shall be forthwith (and, in any
event, within two Business Days) deposited by such Grantor in the exact form
received, duly indorsed by such Grantor to the Administrative Agent if required,
in a Collateral Account maintained under the sole dominion and control of the
Administrative Agent, subject to withdrawal by the Administrative Agent for the
account of the Lenders only as provided in Section 6.5, and (ii) until so turned
over, shall be held by such Grantor in trust for the Administrative Agent and
the Lenders, segregated from other funds of such Grantor. Each such deposit of
Proceeds of Receivables shall be accompanied by a report identifying in
reasonable detail the nature and source of the payments included in the deposit.

            (c) At the Administrative Agent's request at any time an Event of
Default has occurred and is continuing, each Grantor shall deliver to the

            6.2 Communications with Obligors; Grantors Remain Liable.

            (a) The Administrative Agent in its own name or in the name of
others may at any time after the occurrence and during the continuance of an
Event of Default communicate with obligors under the Receivables and the General
Intangibles to verify with them to the Administrative Agent's satisfaction the
existence, amount and terms of any Receivables or General Intangible.

            (b) Upon the request of the Administrative Agent at any time after
the occurrence and during the continuance of an Event of Default, each Grantor
shall notify obligors on the Receivables and the General Intangibles that the
Receivables and the General Intangibles have been assigned to the Administrative
Agent for the ratable benefit of the Lenders and that payments in respect
thereof shall be made directly to the Administrative Agent.

            (c) Anything herein to the contrary notwithstanding, each Grantor
shall remain liable under each of the Receivables and General Intangibles to
observe and perform all the conditions and obligations to be observed and
performed by it thereunder, all in accordance with the terms of any agreement
giving rise thereto. Neither the Administrative Agent nor any Lender shall have
any obligation or liability under any Receivable (or any agreement giving rise
thereto) or General Intangible by reason of or arising out of this Agreement or
the receipt by the Administrative Agent or any Lender of any payment relating
thereto, nor shall the Administrative Agent or any Lender be obligated in any
manner to perform any of the obligations of any Grantor under or pursuant to any
Receivable (or any agreement giving rise thereto) or General Intangible, to make
any payment, to make any inquiry as to the nature or the sufficiency of any
payment received by it or as to the sufficiency of any performance by any party
thereunder, to present or file any claim, to take any action to enforce any
performance or to collect the payment of any amounts which may have been
assigned to it or to which it may be entitled at any time or times.

            6.3 Pledged Stock.

            (a) Unless an Event of Default shall have occurred and be
continuing and the Administrative Agent shall have given notice to the relevant
Grantor of the Administrative Agent's intent to exercise its corresponding
rights pursuant to Section 6.3(b), each Grantor shall be permitted to receive
all cash dividends paid in respect of the Pledged Stock and all payments made in
respect of the Pledged Notes, in each case paid in the normal course of business
of the relevant Issuer and consistent with past practice, to the extent
permitted in the Credit Agreement, and to exercise all voting and corporate
rights with respect to the Pledged Securities; provided, however, that no vote
shall be cast or corporate right exercised or other action taken which, in the
Administrative Agent's reasonable judgment, would impair the Collateral in any
material respect or which is inconsistent with or results in any violation of
any provision of the Credit Agreement, this Agreement or any other Credit
Document.

            (b) If an Event of Default shall occur and be continuing and the
Administrative Agent shall give notice of its intent to exercise such rights to
the relevant Grantor or Grantors, (i) the Administrative Agent shall have the
right to receive any and all cash dividends, payments or other Proceeds paid in
respect of the Pledged Securities and make application thereof to the
Obligations in the order set forth in Section 6.5, and (ii) any or all of

Agent or its nominee, and the Administrative Agent or its nominee may thereafter
exercise (x) all voting, corporate and other rights pertaining to such Pledged

otherwise and (y) any and all rights of conversion, exchange and subscription
and any other rights, privileges or options pertaining to such Pledged
Securities as if it were the absolute owner thereof (including, without
limitation, the right to exchange at its discretion any and all of the Pledged
Securities upon the merger, consolidation, reorganization, recapitalization or
other fundamental change in the corporate structure of any Issuer, or upon the
exercise by any Grantor or the Administrative Agent of any right, privilege or
option pertaining to such Pledged Securities, and in connection therewith, the
right to deposit and deliver any and all of the Pledged Securities with any
committee, depositary, transfer agent, registrar or other designated agency upon
such terms and conditions as the Administrative Agent may determine), all
without liability except to account for property actually received by it, but
the Administrative Agent shall have no duty to any Grantor to exercise any such
right, privilege or option and shall not be responsible for any failure to do so
or delay in so doing.

            (c) Each Grantor hereby authorizes and instructs each Issuer of
any Pledged Securities pledged by such Grantor hereunder to (i) comply with any
instruction received by it from the Administrative Agent in writing that (x)
states that an Event of Default has occurred and is continuing and (y) is
otherwise in accordance with the terms of this Agreement, without any other or
further instructions from such Grantor, and each Grantor agrees that each Issuer
shall be fully protected in so complying, and (ii) unless otherwise expressly
permitted hereby, pay any dividends or other payments with respect to the
Pledged Securities directly to the Administrative Agent.

            6.4 Proceeds to be Turned Over to Administrative Agent. In
addition to the rights of the Administrative Agent and the Lenders specified in
Section 6.1 with respect to payments of Receivables, if an Event of Default
shall occur and be continuing, all Proceeds received by any Grantor consisting
of cash, checks and other near-cash items shall be held by such Grantor in trust
for the Administrative Agent and the Lenders, segregated from other funds of
such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over
to the Administrative Agent in the exact form received by such Grantor (duly
indorsed by such Grantor to the Administrative Agent, if required). All Proceeds
received by the Administrative Agent hereunder shall be held by the
Administrative Agent in a Collateral Account maintained under its sole dominion
and control. All Proceeds while held by the Administrative Agent in a Collateral
Account (or by such Grantor in trust for the Administrative Agent and the
Lenders) shall continue to be held as collateral security for all the
Obligations and shall not constitute payment thereof until applied as provided
in Section 6.5.

            6.5 Application of Proceeds. At such intervals as may be agreed
upon by the Borrower and the Administrative Agent, or, if an Event of Default
shall have occurred and be continuing, at any time at the Agents' election, the
Administrative Agent may apply all or any part of Proceeds constituting
Collateral, whether or not held in any Collateral Account, and any proceeds of
the guarantee set forth in Section 2, in payment of the Obligations in the
following order:

                       Guarantee and Collateral Agreement

<PAGE>
                                       20


            First, to pay incurred and unpaid fees and expenses of the
      Administrative Agent under the Credit Documents;

            Second, to the Administrative Agent, for application by it towards
      payment of amounts then due and owing and remaining unpaid in respect of
      the Obligations, pro rata among the Lenders according to the amounts of
      the Obligations then due and owing and remaining unpaid to the Lenders;

            Third, to the Administrative Agent, for application by it towards
      prepayment of the Obligations, pro rata among the Lenders according to the
      amounts of the Obligations then held by the Lenders; and

            Fourth, any balance of such Proceeds remaining after the Obligations
      shall have been paid in full, no Letters of Credit shall be outstanding
      and the Commitments shall have terminated shall be paid over to the
      Borrower or to whomsoever may be lawfully entitled to receive the same.

            6.6 Code and Other Remedies. If an Event of Default shall occur and
be continuing, the Administrative Agent, on behalf of the Lenders, may exercise,
in addition to all other rights and remedies granted to them in this Agreement
and in any other instrument or agreement securing, evidencing or relating to the
Obligations, all rights and remedies of a secured party under the New York UCC
or any other applicable law. Without limiting the generality of the foregoing,
the Administrative Agent, without demand of performance or other demand,
presentment, protest, advertisement or notice of any kind (except any notice
required by law referred to below) to or upon any Grantor or any other Person
(all and each of which demands, defenses, advertisements and notices are hereby
waived), may in such circumstances forthwith collect, receive, appropriate and
realize upon the Collateral, or any part thereof, and/or may forthwith sell,
lease, assign, give option or options to purchase, or otherwise dispose of and
deliver the Collateral or any part thereof (or contract to do any of the
foregoing), in one or more parcels at public or private sale or sales, at any
exchange, broker's board or office of the Administrative Agent or any Lender or
elsewhere upon such terms and conditions as it may deem advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. The Administrative Agent or any Lender shall have
the right upon any such public sale or sales, and, to the extent permitted by
law, upon any such private sale or sales, to purchase the whole or any part of
the Collateral so sold, free of any right or equity of redemption in any
Grantor, which right or equity is hereby waived and released. Each Grantor
further agrees, at the Administrative Agent's request to assemble the Collateral
and make it available to the Administrative Agent at places which the
Administrative Agent shall reasonably select, whether at such Grantor's premises
or elsewhere. The Administrative Agent shall apply the net proceeds of any
action taken by it pursuant to this Section 6.6, after deducting all reasonable
costs and expenses of every kind incurred in connection therewith or incidental
to the care or safekeeping of any of the Collateral or in any way relating to
the Collateral or the rights of the Administrative Agent and the Lenders
hereunder, including, without limitation, reasonable attorneys' fees and
disbursements, to the payment in whole or in part of the Obligations, in such
order as the Administrative Agent may elect, and only after such application and
after the payment by the Administrative Agent of any other amount required by
any provision of law, including, without limitation, Section 9-504(l)(c) of the
New York UCC, need

                       Guarantee and Collateral Agreement

<PAGE>
                                       21


the Administrative Agent account for the surplus, if any, to any Grantor. To the
extent permitted by applicable law, each Grantor waives all claims, damages and
demands it may acquire against the Administrative Agent or any Lender arising
out of the exercise by them of any rights hereunder. If any notice of a proposed
sale or other disposition of Collateral shall be required by law, such notice
shall be deemed reasonable and proper if given at least 10 days before such sale
or other disposition.

            6.7 Waiver; Deficiency. Each Grantor waives and agrees not to
assert any rights or privileges which it may acquire under Section 9-112 of the
New York UCC. Each Grantor shall remain liable for any deficiency if the
proceeds of any sale or other disposition of the Collateral are insufficient to
pay its Obligations and the fees and disbursements of any attorneys employed by
the Agents or any Lender to collect such deficiency.

                       SECTION 7. THE ADMINISTRATIVE AGENT

            7.1 Administrative Agent's Appointment as Attorney-in-Fact, etc.

            (a) Without limiting any rights or powers granted by this
Agreement to the Administrative Agent while no Event of Default has occurred and
is continuing, each Grantor hereby irrevocably constitutes and appoints the
Administrative Agent and any officer or agent thereof, with full power of
substitution, as its true and lawful attorney-in-fact with full irrevocable
power and authority in the place and stead of such Grantor and in the name of
such Grantor or in its own name at any time an Event of Default has occurred and
is continuing, for the purpose of carrying out the terms of this Agreement, to
take any and all appropriate action and to execute any and all documents and
instruments which may be necessary or desirable to accomplish the purposes of
this Agreement, and, without limiting the generality of the foregoing, each
Grantor hereby gives the Administrative Agent the power and right, on behalf of
such Grantor, without notice to or assent by such Grantor, to do any or all of
the following at any time an Event of Default has occurred and is continuing:

            (i) in the name of such Grantor or its own name, or otherwise, take
      possession of and indorse and collect any checks, drafts, notes,
      acceptances or other instruments for the payment of moneys due under any
      Receivable or General Intangible or with respect to any other Collateral
      and file any claim or take any other action or proceeding in any court of
      law or equity or otherwise deemed appropriate by the Administrative Agent
      for the purpose of collecting any and all such moneys due under any
      Receivable or General Intangible or with respect to any other Collateral
      whenever payable;

            (ii) in the case of any Intellectual Property, execute and deliver,
      and have recorded, any and all agreements, instruments, documents and
      papers as the Administrative Agent may request to evidence the
      Administrative Agent's and the Lenders' security interest in such
      Intellectual Property and the goodwill and general intangibles of such
      Grantor relating thereto or represented thereby;

                       Guarantee and Collateral Agreement

<PAGE>
                                       22


            (iii) pay or discharge taxes and Liens levied or placed on or
      threatened against the Collateral, effect any repairs or any insurance
      called for by the terms of this Agreement and pay all or any part of the
      premiums therefor and the costs thereof,

            (iv) execute, in connection with any sale provided for in Section
      6.6, any endorsements, assignments or other instruments of conveyance or
      transfer with respect to the Collateral; and

            (v) (1) direct any party liable for any payment under any of the
      Collateral to make payment of any and all moneys due or to become due
      thereunder directly to the Administrative Agent or as the Administrative
      Agent shall direct; (2) ask or demand for, collect, and receive payment of
      and receipt for, any and all moneys, claims and other amounts due or to
      become due at any time in respect of or arising out of any Collateral; (3)
      sign and indorse any invoices, freight or express bills, bills of lading,
      storage or warehouse receipts, drafts against debtors, assignments,
      verifications, notices and other documents in connection with any of the
      Collateral; (4) commence and prosecute any suits, actions or proceedings
      at law or in equity in any court of competent jurisdiction to collect the
      Collateral or any portion thereof and to enforce any other right in
      respect of any Collateral; (5) defend any suit, action or proceeding
      brought against such Grantor with respect to any Collateral; (6) settle,
      compromise or adjust any such suit, action or proceeding and, in
      connection therewith, give such discharges or releases as the
      Administrative Agent may deem appropriate; (7) assign any Copyright,
      Patent or Trademark (along with the goodwill of the business to which any
      such Copyright, Patent or Trademark pertains), throughout the world for
      such term or terms, on such conditions, and in such manner, as the
      Administrative Agent shall in its sole discretion determine; and (8)
      generally, sell, transfer, pledge and make any agreement with respect to
      or otherwise deal with any of the Collateral as fully and completely as
      though the Administrative Agent were the absolute owner thereof for all
      purposes, and do, at the Administrative Agent's option and such Grantor's
      expense, at any time, or from time to time, all acts and things which the
      Administrative Agent deems necessary to protect, preserve or realize upon
      the Collateral and the Administrative Agent's and the Lenders' security
      interests therein and to effect the intent of this Agreement, all as fully
      and effectively as such Grantor might do.

            Anything in this Section 7.1(a) to the contrary notwithstanding, the
Administrative Agent agrees that it will not exercise any rights under the power
of attorney provided for in this Section 7.1(a) unless an Event of Default shall
have occurred and be continuing.

            (b) If any Grantor fails to perform or comply with any of its
agreements contained herein, the Administrative Agent, at its option, but
without any obligation so to do, may perform or comply, or otherwise cause
performance or compliance, with such agreement.

            (c) The expenses of the Administrative Agent incurred in
connection with actions undertaken as provided in this Section 7.1, together
with interest thereon at a rate per annum equal to the rate per annum at which
interest would then be payable on past due Revolving Credit Loans that are Base
Rate Loans under the Credit Agreement, from the date of

                       Guarantee and Collateral Agreement

<PAGE>
                                       23


payment by the Administrative Agent to the date reimbursed by the relevant
Grantor, shall be payable by such Grantor to the Administrative Agent on demand.

            (d) Each Grantor hereby ratifies all that said attorneys shall
lawfully do or cause to be done by virtue hereof. All powers, authorizations and
agencies contained in this Agreement are coupled with an interest and are
irrevocable until this Agreement is terminated and the security interests
created hereby are released.

            7.2 Duty of Administrative Agent. The Administrative Agent's sole
duty with respect to the custody, safekeeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the New York UCC or
otherwise, shall be to deal with it in the same manner as the Administrative
Agent deals with similar property for its own account. Neither the
Administrative Agent, any Lender nor any of their respective officers,
directors, employees or agents shall be liable for failure to demand, collect or
realize upon any of the Collateral or for any delay in doing so or shall be
under any obligation to sell or otherwise dispose of any Collateral upon the
request of any Grantor or any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof. The powers
conferred on the Administrative Agent and the Lenders hereunder are solely to
protect the Administrative Agent's and the Lenders' interests in the Collateral
and shall not impose any duty upon the Administrative Agent or any Lender to
exercise any such powers. The Administrative Agent and the Lenders shall be
accountable only for amounts that they actually receive as a result of the
exercise of such powers, and neither they nor any of their officers, directors,
employees or agents shall be responsible to any Grantor for any act or failure
to act hereunder, except for their own gross negligence or willful misconduct.

            7.3 Execution of Financing Statements. Pursuant to Section 9-402
of the New York UCC and any other applicable law, each Grantor authorizes the
Administrative Agent to file or record financing statements and other filing or
recording documents or instruments with respect to the Collateral without the
signature of such Grantor in such form and in such offices as the Administrative
Agent reasonably determines appropriate to perfect the security interests of the
Administrative Agent under this Agreement. A photographic or other reproduction
of this Agreement shall be sufficient as a financing statement or other filing
or recording document or instrument for filing or recording in any jurisdiction.

            7.4 Authority of Administrative Agent. Each Grantor acknowledges
that the rights and responsibilities of the Administrative Agent under this
Agreement with respect to any action taken by the Administrative Agent or the
exercise or non-exercise by the Administrative Agent of any option, voting
right, request, judgment or other right or remedy provided for herein or
resulting or arising out of this Agreement shall, as between the Administrative
Agent and the Grantors, the Administrative Agent shall be conclusively presumed
to be acting as agent for the Lenders with full and valid authority so to act or
refrain from acting, and no Grantor shall be under any obligation, or
entitlement, to make any inquiry respecting such authority.

                              SECTION 8. MISCELLANEOUS

            8.1 Amendments in Writing. None of the terms or provisions of this
Agreement may be waived, amended, supplemented or otherwise modified except in
accordance with Section 8.1 of the Credit Agreement.

            8.2 Notices. All notices, requests and demands to or upon the
Administrative Agent or any Grantor hereunder shall be effected in the manner
provided for in Section 8.2 of the Credit Agreement; provided that any such
notice, request or demand to or upon any Guarantor shall be addressed to such
Guarantor at its notice address set forth on Schedule 1.

            8.3 No Waiver by Course of Conduct; Cumulative Remedies. Neither
the Agents nor any Lender shall by any act (except by a written instrument
pursuant to Section 8.1 of the Credit Agreement), delay, indulgence, omission or
otherwise be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Default or Event of Default. No failure to exercise, nor any
delay in exercising, on the part of any Agent or any Lender, any right, power or
privilege hereunder shall operate as a waiver thereof. No single or partial
exercise of any right, power or privilege hereunder shall preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
A waiver by any Agent or any Lender of any right or remedy hereunder on any one
occasion shall not be construed as a bar to any right or remedy which such Agent
or such Lender would otherwise have on any future occasion. The rights and
remedies herein provided are cumulative, may be exercised singly or concurrently
and are not exclusive of any other rights or remedies provided by law.

            8.4 Enforcement Expenses; Indemnification.

            (a) Each Guarantor agrees to pay or reimburse each Lender and the
Administrative Agent for all its costs and expenses incurred in collecting
against such Guarantor under the guarantee contained in Section 2 or otherwise
enforcing or preserving any rights under this Agreement and the other Credit
Documents to which such Guarantor is a party, including, without limitation, the
fees and disbursements of counsel (including the allocated fees and expenses of
in-house counsel) to each Lender and of counsel to the Administrative Agent.

            (b) Each Guarantor agrees to pay, and to save the Administrative
Agent and the Lenders harmless from, any and all liabilities with respect to, or
resulting from any delay in paying, any and all stamp, excise, sales or other
taxes which may be payable or determined to be payable with respect to any of
the Collateral or in connection with any of the transactions contemplated by
this Agreement.

            (c) Each Guarantor agrees to pay, and to save the Administrative
Agent and the Lenders harmless from, any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever with respect to the execution,
delivery, enforcement, performance and administration of this Agreement to the
extent the Borrower would be required to do so pursuant to Section 9.5 of the
Credit Agreement.

<PAGE>
                                       25


            (d) The agreements in this Section 8.4 shall survive repayment of
the Obligations and all other amounts payable under the Credit Agreement and the
other Credit Documents.

            8.5 Successors and Assigns. This Agreement shall be binding upon
the successors and assigns of each Grantor and shall inure to the benefit of the
Agents and the Lenders and their successors and assigns; provided that no
Grantor may assign, transfer or delegate any of its rights or obligations under
this Agreement without the prior written consent of the Agents.

            8.6 Set-Off. In addition to any rights and remedies of the
Administrative Agent and the Lenders provided by law, the Administrative Agent
and each Lender shall have the right, without prior notice to any Grantor, any
such notice being expressly waived by each Grantor to the extent permitted by
applicable law, upon any amount becoming due and payable by such Grantor under
the Credit Agreement or any other Credit Document (whether at the stated
maturity, by acceleration or otherwise), to set off and appropriate and apply
against such amount any and all deposits (general or special, time or demand,
provisional or final), in any currency, and any other credits, indebtedness or
claims, in any currency, in each case whether direct or indirect, absolute or
contingent, matured or unmatured, at any time held or owing by the
Administrative Agent or such Lender or any branch or agency thereof to or for
the credit or the account of such Grantor, as the case may be. Each Lender
agrees promptly to notify the relevant Grantor and the Administrative Agent
after any such setoff and application made by such Lender; provided that the
failure to give such notice shall not affect the validity of such setoff and
application.

            8.7 Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

            8.8 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            8.9 Section Headings. The Section headings used in this Agreement
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

            8.10 Integration. This Agreement and the other Credit Documents
represent the agreement of the Grantors, the Agents and the Lenders with respect
to the subject matter hereof and thereof, and there are no promises,
undertakings, representations or warranties by the Agents or any Lender relative
to subject matter hereof and thereof not expressly set forth or referred to
herein or in the other Credit Documents.

            8.11 GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

            8.12 Submission to Jurisdiction; Waivers.  Each Grantor hereby
irrevocably and unconditionally:

            (a) submits for itself and its property in any legal action or
      proceeding relating to this Agreement and the other Credit Documents to
      which it is a party, or for recognition and enforcement of any judgment in
      respect thereof, to the non-exclusive general jurisdiction of the Courts
      of the State of New York, the courts of the United States of America for
      the Southern District of New York, and appellate courts from any thereof;

            (b) consents that any such action or proceeding may be brought in
      such courts and waives any objection that it may now or hereafter have to
      the venue of any such action or proceeding in any such court or that such
      action or proceeding was brought in an inconvenient court and agrees not
      to plead or claim the same;

            (c) agrees that service of process in any such action or proceeding
      may be effected by mailing a copy thereof by registered or certified mail
      (or any substantially similar form of mail), postage prepaid, to such
      Grantor at its address referred to in Section 8.2 or at such other address
      of which the Administrative Agent shall have been notified pursuant
      thereto;

            (d) agrees that nothing herein shall affect the right to effect
      service of process in any other manner permitted by law or shall limit the
      right to sue in any other jurisdiction; and

            (e) waives, to the maximum extent not prohibited by law, any right
      it may have to claim or recover in any legal action or proceeding referred
      to in this Section 8.12 any special, exemplary, punitive or consequential
      damages.

            8.13 Acknowledgements.  Each Grantor hereby acknowledges that:

            (a) it has been advised by counsel in the negotiation, execution and
      delivery of this Agreement and the other Credit Documents to which it is a
      party;

            (b) neither the Agents nor any Lender has any fiduciary relationship
      with or duty to any Grantor arising out of or in connection with this
      Agreement or any of the other Credit Documents, and the relationship
      between the Grantors, on the one hand, and

                       Guarantee and Collateral Agreement

                                       27


      the Agents and Lenders, on the other hand, in connection herewith or
      therewith is solely that of debtor and creditor; and

            (c) no joint venture is created hereby or by the other Credit
      Documents or otherwise exists by virtue of the transactions contemplated
      hereby among the Lenders or among the Grantors and the Lenders.

            8.14 Additional Guarantors. Each Subsidiary of the Company that is
required to become a party to this Agreement pursuant to Section 5.9(c) of the
Credit Agreement shall become a Guarantor (and, thereby a Grantor) for all
purposes of this Agreement upon execution and delivery by such Subsidiary of an
Assumption Agreement in the form of Annex I hereto.

            8.15 Releases.

            (a) At such time as the Loans and the other Obligations shall have
been paid in full, the Commitments have been terminated and no Letters of Credit
shall be outstanding, the Collateral shall be released from the Liens created
hereby, and this Agreement and all obligations (other than those expressly
stated to survive such termination) of the Agents and each Grantor hereunder
shall terminate, all without delivery of any instrument or performance of any
act by any party, and all rights to the Collateral shall revert to the Grantors.
At the request and sole expense of any Grantor following any such termination,
the Administrative Agent shall deliver to such Grantor any Collateral held by
the Administrative Agent hereunder, and execute and deliver to such Grantor such
documents as such Grantor shall reasonably request to evidence such termination.

            (b) If any of the Collateral shall be sold, transferred or
otherwise disposed of by any Grantor in a transaction permitted by the Credit
Agreement, then the Administrative Agent, at the request and sole expense of
such Grantor, shall execute and deliver to such Grantor all releases or other
documents reasonably necessary or desirable for the release of the Liens created
hereby on such Collateral. At the request and sole expense of the Borrower, a
Guarantor shall be released from its obligations hereunder in the event that
such Guarantor ceases to be a Subsidiary of the Company by virtue of being sold,
transferred or otherwise disposed of in a transaction permitted by the Credit
Agreement; provided that the Borrower shall have delivered to the Administrative
Agent at least ten Business Days prior to the date of the proposed release, a
written request for release identifying the relevant Guarantor and the terms of
the sale or other disposition in reasonable detail, including the price thereof
and any expenses in connection therewith, together with a certification by the
Borrower stating that such transaction is in compliance with the Credit
Agreement and the other Credit Documents.

UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING
TO THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

contrary contained herein or in the other Credit Documents, no action shall be
taken by the Administrative Agent pursuant to this Agreement, the Credit
Agreement or any other Credit

                                       28


Document with respect to any item of Collateral that would constitute or result
in any assignment of any Governmental Approval or any change of control of the
holder of such Governmental Approval without first obtaining the prior approval
of the relevant Governmental Authority, if, under the existing law, such
assignment of any such Governmental Approval or change of control would require
the prior approval of such Governmental Authority. Prior to the exercise by the
Administrative Agent of any power, right, privilege or remedy pursuant to this

                                   HADLEY & McCLOY LLP]

                                                      February 2, 2000

To the Administrative Agent and
each of the Lenders party to the
Credit Agreement referred to below:

                             Re: Birch Telecom, Inc.

Ladies and Gentlemen:

            We have acted as special New York counsel to Lehman Commercial Paper
Inc. in connection with (i) that certain Amended and Restated Credit Agreement
dated as of February 2, 2000 (the "Credit Agreement") among BIRCH TELECOM, INC.,
a Delaware corporation (the "Company"), BIRCH TELECOM FINANCE, INC., a Delaware
corporation (the "Borrower"), the several banks and other financial institutions
or entities from time to time parties thereto (the "Lenders") and LEHMAN
COMMERCIAL PAPER INC., as administrative agent (in such capacity, the
"Administrative Agent"), providing for, among other things, extensions of credit
to be made by the Lenders to the Borrower in an aggregate principal amount not
exceeding $125,000,000 and (ii) the various agreements and instruments referred
to in the next following paragraph. Except where indicated, capitalized terms
used in this opinion and not otherwise defined herein shall have the meanings
given them by the Credit Agreement. This opinion letter is being delivered
pursuant to Section 4.1(f)(iii) of the Credit Agreement.

            In rendering the opinions expressed below, we have examined the
Credit Agreement and the Guarantee and Collateral Agreement (collectively, the
"Credit Documents"), and have made such examination of laws as we have deemed
relevant for the purposes hereof. In our examination, we have assumed the
authenticity of all documents submitted to us as originals and the conformity
with authentic original documents of all documents submitted to us as copies.
When relevant facts were not independently established, we have relied upon
representations made in or pursuant to the Credit Documents.

              Legal Opinion of Milbank, Tweed, Hadley & McCloy LLP
<PAGE>
                                     - 2 -


            In rendering the opinions expressed below, we have assumed, with
respect to the Credit Documents, that:

            (i)   the Credit Documents have been duly authorized by, have been
                  duly executed and delivered by, and (except to the extent set
                  forth in the opinions expressed below as to the Credit
                  Parties) constitute legal, valid, binding and enforceable
                  obligations of, all of the parties thereto;

            (ii)  all signatories to the Credit Documents have been duly
                  authorized; and

            (iii) all of the parties to the Credit Documents are duly organized
                  and validly existing and have the power and authority
                  (corporate or other) to execute, deliver and perform the
                  Credit Documents.

            Based upon and in reliance on the foregoing, and subject to the
assumptions and qualifications hereinafter set forth, we are of the opinion
that:

            1. Each Credit Document constitutes the legal, valid and binding
      obligation of each Credit Party party thereto, enforceable against such
      Credit Party in accordance with its respective terms, except as may be
      limited by bankruptcy, insolvency, reorganization, fraudulent conveyance,
      moratorium or other similar laws relating to or affecting the rights of
      creditors generally and except as the enforceability of the Credit
      Documents is subject to the application of general principles of equity
      (regardless of whether considered in a proceeding in equity or at law),
      including (a) the possible unavailability of specific performance,
      injunctive relief or any other equitable remedy and (b) concepts of
      materiality, reasonableness, good faith and fair dealing.

            2. The Guarantee and Collateral Agreement is effective to create, in
      favor of the Administrative Agent for the benefit of the Administrative
      Agent and the Lenders, a valid security interest under the Uniform
      Commercial Code as in effect in the State of New York (the "Uniform
      Commercial Code") in all of the right, title and interest of each Credit
      Party party thereto in, to and under the Collateral (as defined in the
      Guarantee and Collateral Agreement) as collateral security for the payment
      of the Obligations (as so defined).

            3. The security interest referred to in paragraph 2 above in that
      portion of the Collateral consisting of Pledged Stock (as defined in the
      Guarantee and Collateral Agreement) represented by certificates in bearer
      form or in registered form indorsed (as provided in Section 8-102(a)(11)

      an effective indorsement (as so provided) or registered in the name of the
      Administrative Agent will, upon the creation of such

      security interest, be perfected by the Administrative Agent taking
      possession thereof in the State of New York, and such perfected security
      interest will remain perfected thereafter so long as such certificates are
      retained by the Administrative Agent in its possession in the State of New
      York. If such security interest therein is perfected by the Administrative
      Agent in the manner specified in the immediately preceding sentence for
      value without notice (within the meaning of Section 8-105 of the Uniform
      Commercial Code) of any adverse claim (within the meaning of Section
      8-102(a)(1) of the Uniform Commercial Code) to the Pledged Stock so
      represented by certificates, then the Administrative Agent will acquire
      such security interest free of any adverse claim (as so defined).

            The foregoing opinions are subject to the following comments and
qualifications:

            A. The enforceability of Section 9.5 of the Credit Agreement (and
      any similar provisions in any of the other Credit Documents) may be
      limited by laws restricting the enforceability of provisions exculpating
      or exempting a party, or requiring indemnification of a party for,
      liability for its own action or inaction, to the extent the action or
      inaction involves gross negligence, recklessness, willful misconduct or
      unlawful conduct.

            B. The enforceability of provisions in the Credit Documents to the
      effect that terms may not be waived or modified except in writing may be
      limited under certain circumstances.

            C. Sections 2.1(c), 2.4 and 2.5 of the Guarantee and Collateral
      Agreement may not be enforceable to the extent that the Obligations (as
      defined in the Guarantee and Collateral Agreement) are materially
      modified.

            D. We express no opinion as to (i) the effect of the laws of any
      jurisdiction in which any Lender is located (other than the State of New
      York) that limit the interest, fees or other charges such Lender may
      impose, (ii) the penultimate sentence of Section 9.6(b) of the Credit
      Agreement and (iii) Section 9.12(a) of the Credit Agreement, insofar as
      such section relates to the subject matter jurisdiction of the United
      States District Court for the Southern District of New York to adjudicate
      any controversy related to any of the Credit Documents.

            E. We express no opinion as to the applicability to the obligations
      of any Credit Party of Section 548 of the Bankruptcy Code of 1978, as
      amended (the "Bankruptcy Code"), Article 10 of the New York Debtor and
      Creditor Law or any other provision of law relating to fraudulent
      conveyances, transfers or obligations.

            F. We wish to point out that the obligations of the Credit Parties,
      and the rights and remedies of the Administrative Agent and the Lenders,
      under the Guarantee and Collateral Agreement may be subject to possible
      limitations upon the exercise of remedial or procedural provisions
      contained in the Guarantee and Collateral Agreement, provided that such
      limitations do not, in our opinion (but subject to the other comments and
      qualifications set forth in this opinion letter), make the remedies and
      procedures that will be afforded to the Administrative Agent and the
      Lenders inadequate for the practical realization of the substantive
      benefits purported to be provided to the Administrative Agent and the
      Lenders by the Guarantee and Collateral Agreement.

            G. With respect to the security interests referred to in paragraph 2
      above, (i) such security interest will continue in the relevant Collateral
      after its sale, exchange or other disposition only to the extent provided
      in Sections 9-306, 9-307 and 9-308 of the Uniform Commercial Code and (ii)
      such security interest in Collateral in which any Credit Party acquires
      rights after the commencement of a case under the Bankruptcy Code in
      respect of such Credit Party may be limited by Section 552 of the
      Bankruptcy Code.

            H. With respect to paragraphs 2 and 3 above, we express no opinion
      as to the creation, perfection or priority of any security interest in (or
      other lien on) any Collateral (as defined in the Guarantee and Collateral
      Agreement) (i) to the extent that, pursuant to Section 9-104 of the
      Uniform Commercial Code, Article 9 of the Uniform Commercial Code does not
      apply thereto, (ii) consisting of uncertificated securities (as defined in
      Section 8-102(a)(18) of the Uniform Commercial Code), (iii) consisting of
      fixtures, timber to be cut or minerals (including oil and gas), (iv)
      covered by a certificate of title or (v) consisting of the proceeds of a
      letter of credit.

            I. We wish to point out that the acquisition by any Credit Party
      after the initial extension of credit under the Credit Agreement of an
      interest in Property that becomes subject to the Lien of the Guarantee and
      Collateral Agreement may constitute a voidable preference under Section
      547 of the Bankruptcy Code.

            J. We express no opinion as to the existence of, or the right, title
      or interest of the Credit Parties in, to or under, any of the Collateral
      (as defined in the Guarantee and Collateral Agreement).

            K. Except as expressly provided in paragraphs 2 and 3 above, we
      express no opinion as to the creation, perfection or priority of any
      security interest in, or other Lien on, the Collateral (as defined in the
      Guarantee and Collateral Agreement).

            The foregoing opinions are limited to matters involving the Federal
laws of the United States and the law of the State of New York, and we do not

any opinion as to the applicability to the transactions under the agreements
referred to herein, or the effect upon such transactions, of the Communications
Act of 1935, and the rules, regulations and policies of the FCC thereunder.

            At the request of our client, this opinion letter is, pursuant to

2.    Employment Terms and Duties

      2.1 Employment. The Company hereby employs the Employee, and the Employee
hereby accepts employment by the Company, upon the terms and conditions set
forth in this Agreement.

      2.2 Term. Subject to the provisions of Section 6, the term of this
Agreement shall be one year, commencing on February 10, 1998. Thereafter, this
Agreement shall be renewed automatically from year to year unless either party
shall have given written notice of termination to the other party at least
ninety (90) days prior to the end of the current term of this Agreement.

      2.3 Duties. The Employee will have such duties as are assigned or
delegated to the Employee by the Board of Directors and President and will serve
as the Senior Vice President of Finance and Chief Financial Officer of the
Company. The Employee will devote substantially all his business time and
attention to the business of the Company, will act in good faith to promote the
success of the Company's business, and will cooperate fully with the Board of
Directors and President in the advancement of the best interests of the Company.
Nothing in this Section 2.3,


                                       3
<PAGE>

however, will prevent the Employee from engaging in additional activities in
connection with personal investments and community affairs that are not
inconsistent with the Employee's duties under this Agreement (which community
affairs shall be disclosed to and approved by the President). If the Employee
serves as a director of the Company or as a director or officer of any of its
Affiliates, the Employee will fulfill his duties as such director or officer
without additional compensation.

3.    Compensation

      3.1 Basic Compensation.

            (a) Salary. The Employee will be paid a minimum base annual salary
      of $200,000 (the "Salary"), which will be payable in equal periodic
      installments according to the Company's customary payroll practices, but
      no less frequently than monthly. The Salary may be increased by the
      Compensation Committee or Board of Directors of the Company during the
      term of this Agreement, and when increased, such higher amount shall then
      be the minimum base annual salary under this Agreement. The Salary shall
      not be reduced below the highest minimum base annual salary fixed from
      time to time by the Compensation Committee or Board of Directors of the
      Company without the Employee's written consent. When increased or
      decreased in accordance with the terms of this Agreement, the new minimum
      base annual salary shall be deemed the Employee's "Salary" for all
      purposes of this Agreement.

            (b) Benefits. The Employee will, during the Employment Period, be
      permitted to participate in such pension, profit sharing, bonus, life
      insurance, disability insurance, hospitalization, major medical, and other
      employee benefit plans of the Company that may be in effect from time to
      time, to the extent the Employee is eligible under the terms of such plans
      (collectively, the "Benefits").

      3.2 Incentive Compensation. The Employee shall be entitled to participate
in an incentive bonus program established by the Board of Directors or the
Compensation Committee of the Board of Directors to measure and reward
management for the financial performance of the Company. The Employee's initial
annual targeted incentive compensation shall be $50,000; provided, however, that
the payment of any incentive compensation shall be at the discretion of the
Compensation Committee of the Board of Directors, which may consider any factors
it deems relevant, including the assessment of the performance of the Employee
and the Company during the relevant time period.

4.    Facilities and Expenses

The Company will furnish the Employee office space, equipment, supplies, and
such other facilities and personnel as the Company deems necessary or
appropriate for the performance of the Employee's duties under this Agreement.
The Company will pay the Employee's dues in such professional societies and
organizations as the President deems appropriate, and will pay on behalf of the
Employee (or reimburse the Employee for) reasonable expenses incurred by the
Employee at the request of, or on behalf of, the Company in the performance of
the Employee's duties pursuant


                                       4
<PAGE>

to this Agreement, and in accordance with the Company's employment policies,
including reasonable expenses incurred by the Employee in attending conventions,
seminars, and other business meetings, in appropriate business entertainment
activities, and for promotional expenses.

5.    Vacations and Holidays

The Employee will be entitled to paid vacation in accordance with the vacation
policies of the Company in effect for its employee officers from time to time.
Vacation must be taken by the Employee at such time or times as approved by the
President. The Employee will also be entitled to the paid holidays set forth in
the Company's policies.

6.    Termination

      6.1 Events of Termination. The Employment Period, the Employee's Salary,
Benefits, and Incentive Compensation, and any and all other rights of the
Employee under this Agreement will terminate (except as otherwise provided in
this Section 6):

            (a)  upon the death of the Employee;

            (b) upon the Disability of the Employee (as defined in Section 6.2)
      immediately upon notice from either party to the other;

            (c) for Cause (as defined in Section 6.3), immediately upon notice
      from the Company to the Employee, or at such later time as such notice may
      specify;

            (d) for Good Reason (as defined in Section 6.4) upon not less than
      thirty days' prior notice from the Employee to the Company; or

            (e) without Cause upon not less than thirty days' notice from the
      Company to the Employee.

      6.2 Definition of "Disability." For purposes of Section 6.1, the Employee
will be deemed to have a "Disability" if, for physical or mental reasons, the
Employee is unable to perform the Employee's duties under this Agreement for 120
consecutive days, or 180 days during any twelve month period, as determined in
accordance with this Section 6.2. The Disability of the Employee will be
determined by a medical doctor selected by written agreement of the Company and
the Employee upon the request of either party by notice to the other. If the
Company and the Employee cannot agree on the selection of a medical doctor, each
of them will select a medical doctor and the two medical doctors will select a
third medical doctor who will determine whether the Employee has a Disability.
The determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Employee must submit to a reasonable number of
examinations by the medical doctor making the determination of Disability under
this Section 6.2, and to other specialists designated by such medical doctor,
and the Employee hereby authorizes the disclosure and release to the Company of
such determination and all supporting medical records. If the Employee is not
legally competent, the Employee's legal guardian or duly authorized


                                       5
<PAGE>

attorney-in-fact will act in the Employee's stead under this Section 6.2 for the
purposes of submitting the Employee to the examinations, and providing the
authorization of disclosure, required under this Section 6.2.

      6.3 Definition of "Cause." For purposes of Section 6.1, the term "Cause"
means: (a) the Employee's breach of a material obligation under this Agreement;
(b) the Employee's failure to adhere in any material respect to any written
Company policy if such policy is material to the effective performance by the
Employee of his duties under this Agreement, and if the Employee has been given
a reasonable opportunity to cure his failure to comply within the thirty-day
period preceding termination of this Agreement, provided that if the Employee
cures his failure to comply with such a policy and then fails again to comply
with the same policy, no further opportunity to cure that failure shall be
required; (c) the appropriation (or attempted appropriation) of a material
business opportunity of the Company, including attempting to secure or securing
any personal profit in connection with any transaction entered into on behalf of
the Company (other than through stock options, bonuses and other incentives
provided by the Company to the Employee); (d) the misappropriation (or attempted
misappropriation) of any of the Company's funds or property; or (e) the
conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, or a crime involving moral turpitude, dishonesty, or
fraud.

      6.4 Definition of "Good Reason." For purposes of Section 6.1, the term
"Good Reason" shall mean (a) a substantial reduction in the Employee's duties or
responsibilities, (b) any reduction in Employee's Salary, or (c) relocation of
the Employee's primary workplace to a location that is greater than 35 miles
from the Employee's current workplace, in each case which is not cured within 30
days following the Company's receipt of written notice from the Employee
describing the event constituting Good Reason.

      6.5 Termination Pay. Effective upon the expiration or termination of this
Agreement, the Company will be obligated to pay the Employee (or, in the event
of his death, his designated beneficiary as defined below) only such
compensation as is provided in this Section 6.5. For purposes of this Section
6.5 the Employee's designated beneficiary will be such individual beneficiary or
trust, located at such address, as the Employee may designate by notice to the
Company from time to time or, if the Employee fails to give notice to the
Company of such a beneficiary, the Employee's estate. Notwithstanding the
preceding sentence, the Company will have no duty, in any circumstances, to
attempt to open an estate on behalf of the Employee, to determine whether any
beneficiary designated by the Employee is alive or to ascertain the address of
any such beneficiary, to determine the existence of any trust, to determine
whether any Person purporting to act as the Employee's personal representative
(or the trustee of a trust established by the Employee) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee.

      (a) Termination by the Employee for Good Reason or by the Company without
      Cause. If the Employee terminates this Agreement for Good Reason, or if
      the Company terminates this Agreement other than for Cause (but not
      because of the Disability or death of the Employee), or if the Company
      notifies the Employee in accordance with Section 2.2 that this Agreement
      will not be renewed as of an applicable expiration date, the Company will


                                       6
<PAGE>

      pay the Employee (i) the Employee's Salary for the remainder, if any, of
      the calendar month in which such termination is effective and for twelve
      consecutive calendar months thereafter, (ii) the amount of the Employee's
      targeted incentive compensation for the year during which the termination
      is effective (prorated for the period from the beginning of the year until
      the effective date of termination), and (iii) with respect to the
      Post-Employment Period, an additional amount equal to the full amount of
      the Employee's targeted incentive compensation for the year in which the
      termination was effective (such amount to be determined as if the Employee
      had been employed for the entire year and not prorated as described in
      clause (ii) above), payable in equal monthly installments over the
      Post-Employment Period. Notwithstanding the preceding sentence, if the
      Employee obtains other employment prior to the end of the Post-Employment
      Period or any extension thereof, he must promptly give notice thereof to
      the Company, and the payments under this Agreement for any period after
      the Employee obtains other employment will be reduced by the amount of the
      cash compensation received and to be received by the Employee from the
      Employee's other employment for services performed during such period.

            (b) Termination by the Company for Cause. If the Company terminates
      this Agreement for Cause, the Employee will be entitled to receive his
      Salary only through the date such termination is effective.

            (c) Termination upon Disability. If this Agreement is terminated by
      either party as a result of the Employee's Disability, as determined under
      Section 6.2, the Company will pay the Employee his Salary through the
      remainder of the calendar month during which such termination is effective
      and for the lesser of (i) six consecutive months thereafter, or (ii) the
      period until disability insurance benefits commence under any disability
      insurance coverage furnished by the Company to the Employee.

            (d) Termination upon Death. If this Agreement is terminated because
      of the Employee's death, the Employee will be entitled to receive his
      Salary through the end of the calendar month in which his death occurs.

            (e) Benefits. Except as otherwise required by law, the Employee's
      accrual of, or participation in plans providing for, the Benefits will
      cease at the effective date of the termination of this Agreement, and the
      Employee will be entitled to accrued Benefits pursuant to such plans only
      as provided in such plans.

7.    Non-Disclosure Covenant; Employee Inventions

      7.1 Acknowledgments by the Employee. The Employee acknowledges that (a)
during the Employment Period and as a part of his employment, the Employee will
be afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Company and its
business; (c) because the Employee possesses substantial technical expertise and
skill with respect to the Company's business, the Company desires to obtain
exclusive ownership of each Employee Invention, and the Company will be at a
substantial


                                       7
<PAGE>

competitive disadvantage if it fails to acquire exclusive ownership of each
Employee Invention; and (d) the provisions of this Section 7 are reasonable and
necessary to prevent the improper use or disclosure of Confidential Information
and to provide the Company with exclusive ownership of all Employee Inventions.

      7.2 Agreements of the Employee. In consideration of the compensation and
benefits to be paid or provided to the Employee by the Company under this
Agreement, the Employee covenants as follows:

            (a)  Confidentiality.

                  (i) During and following the Employment Period, the Employee
            will hold in confidence the Confidential Information and will not
            disclose it to any Person except with the specific prior written
            consent of the Company or except as otherwise expressly permitted by
            the terms of this Agreement.

                  (ii) Any trade secrets of the Company will be entitled to all
            of the protections and benefits under the Missouri Uniform Trade
            Secrets Act and any other applicable law. If any information that
            the Company deems to be a trade secret is found by a court of
            competent jurisdiction not to be a trade secret for purposes of this
            Agreement, such information will, nevertheless, be considered
            Confidential Information for purposes of this Agreement. The
            Employee hereby waives any requirement that the Company submit proof
            of the economic value of any trade secret or post a bond or other
            security.

                  (iii) None of the foregoing obligations and restrictions
            applies to any part of the Confidential Information that the
            Employee demonstrates was or became generally available to the
            public other than as a result of a disclosure by the Employee or by
            any other Person bound by a confidentiality obligation to the
            Company in respect of such Confidential Information.

                  (iv) The Employee will not remove from the Company's premises
            (except to the extent such removal is for purposes of the
            performance of the Employee's duties at home or while traveling, or
            except as otherwise specifically authorized by the Company) any
            Company document, record, notebook, plan, model, component, device,
            or computer software or code, whether embodied in a disk or in any
            other form (collectively, the "Proprietary Items"). The Employee
            recognizes that, as between the Company and the Employee, all of the
            Proprietary Items, whether or not developed by the Employee, are the
            exclusive property of the Company. Upon termination of this
            Agreement by either party, or upon the request of the Company during
            the Employment Period, the Employee will return to the Company all
            of the Proprietary Items in the Employee's possession or subject to
            the Employee's control, and the Employee shall not retain any
            copies, abstracts, sketches, or other physical embodiment of any of
            the Proprietary Items.


                                       8
<PAGE>

            (b) Employee Inventions. Each Employee Invention will belong
      exclusively to the Company. The Employee acknowledges that all Employee
      Inventions are works made for hire and are the property of the Company,
      including any copyrights, patents, or other intellectual property rights
      pertaining thereto. If it is determined that any such works are not works
      made for hire, the Employee hereby assigns to the Company all of the
      Employee's right, title, and interest, including all rights of copyright,
      patent, and other intellectual property rights, to or in such Employee
      Inventions. The Employee will promptly:

                  (i) disclose to the Company in writing any Employee Invention;

                  (ii) assign to the Company or to a party designated by the
            Company, at the Company's request and without additional
            compensation, all of the Employee's right to the Employee Invention
            for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Company such applications,
            assignments, and other documents as the Company may request in order
            to apply for and obtain patents or other registrations with respect
            to any Employee Invention in the United States and any foreign
            jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
            obligations; and

                  (v) give testimony and render any other assistance in support
            of the Company's rights to any Employee Invention.

      Notwithstanding anything to the contrary herein, provisions otherwise
      requiring the Employee to assign to the Company any invention conceived by
      the Employee shall not apply to an invention for which no equipment,
      supplies, facilities or trade secret information of the Company was used
      and which was developed entirely on the Employee's own time, unless the
      invention relates to the business of the Company or to the Company's
      actual or demonstrably anticipated research or development, or the
      invention results from any work performed by the Employee for the Company.

      7.3 Disputes or Controversies. The Employee recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Employee, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

8.    Non-Competition and Non-Interference

      8.1 Acknowledgments by the Employee. The Employee acknowledges that: (a)
the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary, and intellectual character; (b) the Company
competes with other businesses that are


                                       9
<PAGE>

or could be located in any part of the Territory; and (c) the provisions of this
Section 8 are reasonable and necessary to protect the Company's business.

      8.2 Covenants of the Employee. In consideration of the acknowledgments by
the Employee, and in consideration of the compensation and benefits to be paid
or provided to the Employee by the Company, the Employee covenants that he will
not, directly or indirectly:

            (a) during the Employment Period, except in the course of his
      employment hereunder, and during the Post-Employment Period, engage or
      invest in, own, manage, operate, finance, control, or participate in the
      ownership, management, operation, financing, or control of, be employed
      by, associated with, or in any manner connected with, lend the Employee's
      name or any similar name to, lend Employee's credit to or render services
      or advice to, any Competitive Business within the Territory; provided,
      however, that the Employee may purchase or otherwise acquire up to (but
      not more than) one percent of any class of securities of any enterprise
      (but without otherwise participating in the activities of such enterprise)
      if such securities are listed on any national or regional securities
      exchange or have been registered under Section 12(g) of the Securities
      Exchange Act of 1934;

            (b) whether for the Employee's own account or for the account of any
      other Person, at any time during the Employment Period and the
      Post-Employment Period, solicit business of the same or similar type being
      carried on by the Company, from any Person known by the Employee to be a
      customer of the Company, whether or not the Employee had personal contact
      with such Person during and by reason of the Employee's employment with
      the Company;

            (c) whether for the Employee's own account or the account of any
      other Person at any time during the Employment Period and the
      Post-Employment Period, solicit, employ, or otherwise engage as an
      employee, independent contractor, or otherwise, any person who is or was
      an employee of the Company at any time during the Employment Period or in
      any manner induce or attempt to induce any employee of the Company to
      terminate his or her employment with the Company; or at any time during
      the Employment Period and the Post-Employment Period, interfere with the
      Company's relationship with any person, including any person who at any
      time during the Employment Period was an employee, contractor, supplier,
      or customer of the Company;

            (d) at any time during the Employment Period and the Post-Employment
      Period, disparage the Company or any of its shareholders, directors,
      officers, employees, or agents.

      8.3 Divisible Covenants. If any covenant in Section 8.2 is held to be
unreasonable, arbitrary, or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as a court of
competent jurisdiction may determine to be reasonable, not arbitrary, and not
against public policy, will be effective, binding, and enforceable against the
Employee.


                                       10
<PAGE>

      8.4 Extension of Covenants. The period of time applicable to any covenant
in Section 8.2 will be extended by the duration of any violation by the Employee
of such covenant. In addition, the period of time applicable to the covenants in
Section 8.2 may be extended, at the option of the Company, for a period of one
year after the expiration of the Post-Employment Period, provided that all of
the following conditions have been satisfied: (a) the Company has, within sixty
days of the effective date of termination of Employee's employment, provided
notice to the Employee of the Company's election to extend the period applicable
to the covenants in Section 8.2 for an additional year, (b) the Company has paid
all termination payments it is obligated to pay Employee relating to the
Employment Period and the Post-Employment Period, and (c) for such additional
year after the Post-Employment Period, the Company pays the Employee the sum of
the Employee's Salary plus an amount equal to the full amount of the Employee's
targeted incentive compensation for the year in which the termination was
effective, payable in equal monthly installments over that year.

      8.5 Notices. The Employee will, while the covenants under Section 8.2 are
in effect, give notice to the Company, within ten days after accepting any other
employment, of the identity of the Employee's new employer. The Company may
notify such new employer that the Employee is bound by this Agreement and, at
the Company's election, furnish such new employer with a copy of this Agreement
or relevant portions thereof.

9.    General Provisions

      9.1 Injunctive Relief and Additional Remedy. The Employee acknowledges
that the injury that would be suffered by the Company as a result of a breach of
the provisions of this Agreement (including any provision of Sections 7 and 8)
would be irreparable and that an award of monetary damages to the Company for
such a breach would be an inadequate remedy. Consequently, the Company will have
the right, in addition to any other rights it may have, to obtain injunctive
relief to restrain any breach or threatened breach or otherwise to specifically
enforce any provision of this Agreement, and the Company will not be obligated
to post bond or other security in seeking such relief. Without limiting the
Company's rights under this Section 9 or any other remedies of the Company, if
the Employee breaches any of the provisions of Section 7 or 8, the Company will
have the right to cease making any payments otherwise due to the Employee under
this Agreement.

      9.2 Covenants of Sections 7 and 8 are Essential and Independent Covenants.
The covenants by the Employee in Sections 7 and 8 are essential elements of this
Agreement, and without the Employee's agreement to comply with such covenants,
the Company would not have entered into this Agreement or employed the Employee.
The Company and the Employee have independently consulted their respective
counsel and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Company. The Employee's covenants in Sections 7 and 8 are
independent covenants and the existence of any claim by the Employee against the
Company, under this Agreement or otherwise, will not excuse the Employee's
breach of any covenant in Section 7 or 8. If the Employee's employment hereunder
expires or is terminated, this Agreement will continue in full force and effect
as is necessary or appropriate to enforce the covenants and agreements of the
Employee in Sections 7 and 8.


                                       11
<PAGE>

      9.3 Representations and Warranties by the Employee. The Employee
represents and warrants to the Company that the execution and delivery by the
Employee of this Agreement do not, and the performance by the Employee of the
Employee's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Employee; or (b) conflict with, result in the breach of any provisions of or the
termination of, or constitute a default under, any agreement to which the
Employee is a party or by which the Employee is or may be bound.

      9.4 Obligations Contingent on Performance. The obligations of the Company
hereunder, including its obligation to pay the compensation provided for herein,
are contingent upon the Employee's performance of the Employee's obligations
hereunder.

      9.5 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,

2.    Employment Terms and Duties

      2.1 Employment. The Company hereby employs the Employee, and the Employee
hereby accepts employment by the Company, upon the terms and conditions set
forth in this Agreement.

      2.2 Term. Subject to the provisions of Section 6, the term of this
Agreement shall be one year, commencing on February 10, 1998. Thereafter, this
Agreement shall be renewed automatically from year to year unless either party

ninety (90) days prior to the end of the current term of this Agreement.

      2.3 Duties. The Employee will have such duties as are assigned or
delegated to the Employee by the Board of Directors and President and will serve
as the Senior Vice President of Marketing and Sales of the Company. The Employee
will devote substantially all his business time and attention to the business of
the Company, will act in good faith to promote the success of the Company's
business, and will cooperate fully with the Board of Directors and President in
the advancement of the best interests of the Company. Nothing in this Section

<PAGE>

the Employee from engaging in additional activities in connection with personal
investments and community affairs that are not inconsistent with the Employee's
duties under this Agreement (which community affairs shall be disclosed to and

      of $200,000 (the "Salary"), which will be payable in equal periodic
      installments according to the Company's customary payroll practices, but
      no less frequently than monthly. The Salary may be increased by the
      Compensation Committee or Board of Directors of the Company during the
      term of this Agreement, and when increased, such higher amount shall then
      be the minimum base annual salary under this Agreement. The Salary shall
      not be reduced below the highest minimum base annual salary fixed from
      time to time by the Compensation Committee or Board of Directors of the
      Company without the Employee's written consent. When increased or
      decreased in accordance with the terms of this Agreement, the new minimum
      base annual salary shall be deemed the Employee's "Salary" for all
      purposes of this Agreement.

            (b) Benefits. The Employee will, during the Employment Period, be
      permitted to participate in such pension, profit sharing, bonus, life
      insurance, disability insurance, hospitalization, major medical, and other
      employee benefit plans of the Company that may be in effect from time to
      time, to the extent the Employee is eligible under the terms of such plans
      (collectively, the "Benefits").

      3.2 Incentive Compensation. The Employee shall be entitled to participate
in an incentive bonus program established by the Board of Directors or the
Compensation Committee of the Board of Directors to measure and reward
management for the financial performance of the Company. The Employee's initial
annual targeted incentive compensation shall be $75,000; provided, however, that
the payment of any incentive compensation shall be at the discretion of the
Compensation Committee of the Board of Directors, which may consider any factors
it deems relevant, including the assessment of the performance of the Employee
and the Company during the relevant time period.

4.    Facilities and Expenses

The Company will furnish the Employee office space, equipment, supplies, and
such other facilities and personnel as the Company deems necessary or
appropriate for the performance of the Employee's duties under this Agreement.
The Company will pay the Employee's dues in such professional societies and
organizations as the President deems appropriate, and will pay on behalf of the
Employee (or reimburse the Employee for) reasonable expenses incurred by the
Employee at


                                       4
<PAGE>

the request of, or on behalf of, the Company in the performance of the
Employee's duties pursuant to this Agreement, and in accordance with the
Company's employment policies, including reasonable expenses incurred by the
Employee in attending conventions, seminars, and other business meetings, in
appropriate business entertainment activities, and for promotional expenses.

5.    Vacations and Holidays

The Employee will be entitled to paid vacation in accordance with the vacation
policies of the Company in effect for its employee officers from time to time.
Vacation must be taken by the Employee at such time or times as approved by the
President. The Employee will also be entitled to the paid holidays set forth in
the Company's policies.

6.    Termination

      6.1 Events of Termination. The Employment Period, the Employee's Salary,
Benefits, and Incentive Compensation, and any and all other rights of the
Employee under this Agreement will terminate (except as otherwise provided in
this Section 6):

            (a)  upon the death of the Employee;

            (b) upon the Disability of the Employee (as defined in Section 6.2)
      immediately upon notice from either party to the other;

            (c) for Cause (as defined in Section 6.3), immediately upon notice
      from the Company to the Employee, or at such later time as such notice may
      specify;

            (d) for Good Reason (as defined in Section 6.4) upon not less than
      thirty days' prior notice from the Employee to the Company; or

            (e) without Cause upon not less than thirty days' notice from the
      Company to the Employee.

      6.2 Definition of "Disability." For purposes of Section 6.1, the Employee
will be deemed to have a "Disability" if, for physical or mental reasons, the
Employee is unable to perform the Employee's duties under this Agreement for 120
consecutive days, or 180 days during any twelve month period, as determined in
accordance with this Section 6.2. The Disability of the Employee will be
determined by a medical doctor selected by written agreement of the Company and
the Employee upon the request of either party by notice to the other. If the
Company and the Employee cannot agree on the selection of a medical doctor, each
of them will select a medical doctor and the two medical doctors will select a
third medical doctor who will determine whether the Employee has a Disability.
The determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Employee must submit to a reasonable number of
examinations by the medical doctor making the determination of Disability under
this Section 6.2, and to other specialists designated by such medical doctor,
and the Employee hereby authorizes the disclosure and release to the Company of
such determination and all supporting medical records. If


                                       5
<PAGE>

the Employee is not legally competent, the Employee's legal guardian or duly
authorized attorney-in-fact will act in the Employee's stead under this Section
6.2 for the purposes of submitting the Employee to the examinations, and
providing the authorization of disclosure, required under this Section 6.2.

      6.3 Definition of "Cause." For purposes of Section 6.1, the term "Cause"
means: (a) the Employee's breach of a material obligation under this Agreement;
(b) the Employee's failure to adhere in any material respect to any written
Company policy if such policy is material to the effective performance by the
Employee of his duties under this Agreement, and if the Employee has been given
a reasonable opportunity to cure his failure to comply within the thirty-day
period preceding termination of this Agreement, provided that if the Employee
cures his failure to comply with such a policy and then fails again to comply
with the same policy, no further opportunity to cure that failure shall be
required; (c) the appropriation (or attempted appropriation) of a material
business opportunity of the Company, including attempting to secure or securing
any personal profit in connection with any transaction entered into on behalf of
the Company (other than through stock options, bonuses and other incentives
provided by the Company to the Employee); (d) the misappropriation (or attempted
misappropriation) of any of the Company's funds or property; or (e) the
conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, or a crime involving moral turpitude, dishonesty, or
fraud.

      6.4 Definition of "Good Reason." For purposes of Section 6.1, the term
"Good Reason" shall mean (a) a substantial reduction in the Employee's duties or
responsibilities, (b) any reduction in Employee's Salary, or (c) relocation of
the Employee's primary workplace to a location that is greater than 35 miles
from the Employee's current workplace, in each case which is not cured within 30
days following the Company's receipt of written notice from the Employee
describing the event constituting Good Reason.

      6.5 Termination Pay. Effective upon the expiration or termination of this
Agreement, the Company will be obligated to pay the Employee (or, in the event
of his death, his designated beneficiary as defined below) only such
compensation as is provided in this Section 6.5. For purposes of this Section
6.5 the Employee's designated beneficiary will be such individual beneficiary or
trust, located at such address, as the Employee may designate by notice to the
Company from time to time or, if the Employee fails to give notice to the
Company of such a beneficiary, the Employee's estate. Notwithstanding the
preceding sentence, the Company will have no duty, in any circumstances, to
attempt to open an estate on behalf of the Employee, to determine whether any
beneficiary designated by the Employee is alive or to ascertain the address of
any such beneficiary, to determine the existence of any trust, to determine
whether any Person purporting to act as the Employee's personal representative
(or the trustee of a trust established by the Employee) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee.

            (a) Termination by the Employee for Good Reason or by the Company
      without Cause. If the Employee terminates this Agreement for Good Reason,
      or if the Company terminates this Agreement other than for Cause (but not
      because of the Disability or death


                                       6
<PAGE>

      of the Employee), or if the Company notifies the Employee in accordance
      with Section 2.2 that this Agreement will not be renewed as of an
      applicable expiration date, the Company will pay the Employee (i) the
      Employee's Salary for the remainder, if any, of the calendar month in
      which such termination is effective and for twenty-four consecutive
      calendar months thereafter, (ii) the amount of the Employee's targeted
      incentive compensation for the year during which the termination is
      effective (prorated for the period from the beginning of the year until
      the effective date of termination), and (iii) the sum of two times the
      amount of the Employee's targeted incentive compensation for the year in
      which the termination was effective (such amount to be determined as if
      the Employee had been employed for the entire year and not prorated as
      described in clause (ii) above), payable in equal monthly installments
      over the Post-Employment Period. Notwithstanding the preceding sentence,
      if the Employee obtains other employment prior to the end of the
      twenty-four months following the month in which the termination or
      expiration is effective, he must promptly give notice thereof to the
      Company, and the payments under this Agreement for any period after the
      Employee obtains other employment will be reduced by the amount of the
      cash compensation received and to be received by the Employee from the
      Employee's other employment for services performed during such period.

            (b) Termination by the Company for Cause. If the Company terminates
      this Agreement for Cause, the Employee will be entitled to receive his
      Salary only through the date such termination is effective.

            (c) Termination upon Disability. If this Agreement is terminated by
      either party as a result of the Employee's Disability, as determined under
      Section 6.2, the Company will pay the Employee his Salary through the
      remainder of the calendar month during which such termination is effective
      and for the lesser of (i) six consecutive months thereafter, or (ii) the
      period until disability insurance benefits commence under any disability
      insurance coverage furnished by the Company to the Employee.

            (d) Termination upon Death. If this Agreement is terminated because
      of the Employee's death, the Employee will be entitled to receive his
      Salary through the end of the calendar month in which his death occurs.

            (e) Benefits. Except as otherwise required by law, the Employee's
      accrual of, or participation in plans providing for, the Benefits will
      cease at the effective date of the termination of this Agreement, and the
      Employee will be entitled to accrued Benefits pursuant to such plans only
      as provided in such plans.

7.    Non-Disclosure Covenant; Employee Inventions

      7.1 Acknowledgments by the Employee. The Employee acknowledges that (a)
during the Employment Period and as a part of his employment, the Employee will
be afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Company and its
business; (c) because the Employee possesses substantial


                                       7
<PAGE>

technical expertise and skill with respect to the Company's business, the
Company desires to obtain exclusive ownership of each Employee Invention, and
the Company will be at a substantial competitive disadvantage if it fails to
acquire exclusive ownership of each Employee Invention; and (d) the provisions
of this Section 7 are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information and to provide the Company with exclusive
ownership of all Employee Inventions.

      7.2 Agreements of the Employee. In consideration of the compensation and
benefits to be paid or provided to the Employee by the Company under this
Agreement, the Employee covenants as follows:

            (a)  Confidentiality.

                  (i) During and following the Employment Period, the Employee
            will hold in confidence the Confidential Information and will not
            disclose it to any Person except with the specific prior written
            consent of the Company or except as otherwise expressly permitted by
            the terms of this Agreement.

                  (ii) Any trade secrets of the Company will be entitled to all
            of the protections and benefits under the Missouri Uniform Trade
            Secrets Act and any other applicable law. If any information that
            the Company deems to be a trade secret is found by a court of
            competent jurisdiction not to be a trade secret for purposes of this
            Agreement, such information will, nevertheless, be considered
            Confidential Information for purposes of this Agreement. The
            Employee hereby waives any requirement that the Company submit proof
            of the economic value of any trade secret or post a bond or other
            security.

                  (iii) None of the foregoing obligations and restrictions
            applies to any part of the Confidential Information that the
            Employee demonstrates was or became generally available to the
            public other than as a result of a disclosure by the Employee or by
            any other Person bound by a confidentiality obligation to the
            Company in respect of such Confidential Information.

                  (iv) The Employee will not remove from the Company's premises
            (except to the extent such removal is for purposes of the
            performance of the Employee's duties at home or while traveling, or
            except as otherwise specifically authorized by the Company) any
            Company document, record, notebook, plan, model, component, device,
            or computer software or code, whether embodied in a disk or in any
            other form (collectively, the "Proprietary Items"). The Employee
            recognizes that, as between the Company and the Employee, all of the
            Proprietary Items, whether or not developed by the Employee, are the
            exclusive property of the Company. Upon termination of this
            Agreement by either party, or upon the request of the Company during
            the Employment Period, the Employee will return to the Company all
            of the Proprietary Items in the Employee's possession or subject to
            the Employee's control,

            and the Employee shall not retain any copies, abstracts, sketches,
            or other physical embodiment of any of the Proprietary Items.

            (b) Employee Inventions. Each Employee Invention will belong
      exclusively to the Company. The Employee acknowledges that all Employee
      Inventions are works made for hire and are the property of the Company,
      including any copyrights, patents, or other intellectual property rights
      pertaining thereto. If it is determined that any such works are not works
      made for hire, the Employee hereby assigns to the Company all of the
      Employee's right, title, and interest, including all rights of copyright,
      patent, and other intellectual property rights, to or in such Employee
      Inventions. The Employee will promptly:

                  (i) disclose to the Company in writing any Employee Invention;

                  (ii) assign to the Company or to a party designated by the
            Company, at the Company's request and without additional
            compensation, all of the Employee's right to the Employee Invention
            for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Company such applications,
            assignments, and other documents as the Company may request in order
            to apply for and obtain patents or other registrations with respect
            to any Employee Invention in the United States and any foreign
            jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
            obligations; and

                  (v) give testimony and render any other assistance in support
            of the Company's rights to any Employee Invention.

      Notwithstanding anything to the contrary herein, provisions otherwise
      requiring the Employee to assign to the Company any invention conceived by
      the Employee shall not apply to an invention for which no equipment,
      supplies, facilities or trade secret information of the Company was used
      and which was developed entirely on the Employee's own time, unless the
      invention relates to the business of the Company or to the Company's
      actual or demonstrably anticipated research or development, or the
      invention results from any work performed by the Employee for the Company.

      7.3 Disputes or Controversies. The Employee recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Employee, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary, and intellectual character; (b) the Company
competes with other businesses that are or could be located in any part of the
Territory; and (c) the provisions of this Section 8 are reasonable and necessary
to protect the Company's business.

      8.2 Covenants of the Employee. In consideration of the acknowledgments by
the Employee, and in consideration of the compensation and benefits to be paid
or provided to the Employee by the Company, the Employee covenants that he will
not, directly or indirectly:

            (a) during the Employment Period, except in the course of his
      employment hereunder, and during the Post-Employment Period, engage or
      invest in, own, manage, operate, finance, control, or participate in the
      ownership, management, operation, financing, or control of, be employed
      by, associated with, or in any manner connected with, lend the Employee's
      name or any similar name to, lend Employee's credit to or render services
      or advice to, any Competitive Business within the Territory; provided,
      however, that the Employee may purchase or otherwise acquire up to (but
      not more than) one percent of any class of securities of any enterprise
      (but without otherwise participating in the activities of such enterprise)
      if such securities are listed on any national or regional securities
      exchange or have been registered under Section 12(g) of the Securities
      Exchange Act of 1934;

            (b) whether for the Employee's own account or for the account of any
      other Person, at any time during the Employment Period and the
      Post-Employment Period, solicit business of the same or similar type being
      carried on by the Company, from any Person known by the Employee to be a
      customer of the Company, whether or not the Employee had personal contact
      with such Person during and by reason of the Employee's employment with
      the Company;

            (c) whether for the Employee's own account or the account of any
      other Person at any time during the Employment Period and the
      Post-Employment Period, solicit, employ, or otherwise engage as an
      employee, independent contractor, or otherwise, any person who is or was
      an employee of the Company at any time during the Employment Period or in
      any manner induce or attempt to induce any employee of the Company to
      terminate his or her employment with the Company; or at any time during
      the Employment Period and the Post-Employment Period, interfere with the
      Company's relationship with any person, including any person who at any
      time during the Employment Period was an employee, contractor, supplier,
      or customer of the Company;

            (d) at any time during the Employment Period and the Post-Employment
      Period, disparage the Company or any of its shareholders, directors,
      officers, employees, or agents.

      8.3 Divisible Covenants. If any covenant in Section 8.2 is held to be
unreasonable, arbitrary, or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as


                                       10
<PAGE>

a court of competent jurisdiction may determine to be reasonable, not arbitrary,
and not against public policy, will be effective, binding, and enforceable
against the Employee.

      8.4 Extension of Covenants. The period of time applicable to any covenant
in Section 8.2 will be extended by the duration of any violation by the Employee
of such covenant.

      8.5 Notices. The Employee will, while the covenants under Section 8.2 are
in effect, give notice to the Company, within ten days after accepting any other
employment, of the identity of the Employee's new employer. The Company may
notify such new employer that the Employee is bound by this Agreement and, at
the Company's election, furnish such new employer with a copy of this Agreement
or relevant portions thereof.

9.    General Provisions

      9.1 Injunctive Relief and Additional Remedy. The Employee acknowledges
that the injury that would be suffered by the Company as a result of a breach of
the provisions of this Agreement (including any provision of Sections 7 and 8)
would be irreparable and that an award of monetary damages to the Company for
such a breach would be an inadequate remedy. Consequently, the Company will have
the right, in addition to any other rights it may have, to obtain injunctive
relief to restrain any breach or threatened breach or otherwise to specifically
enforce any provision of this Agreement, and the Company will not be obligated
to post bond or other security in seeking such relief. Without limiting the
Company's rights under this Section 9 or any other remedies of the Company, if
the Employee breaches any of the provisions of Section 7 or 8, the Company will
have the right to cease making any payments otherwise due to the Employee under
this Agreement.

      9.2 Covenants of Sections 7 and 8 are Essential and Independent Covenants.
The covenants by the Employee in Sections 7 and 8 are essential elements of this
Agreement, and without the Employee's agreement to comply with such covenants,
the Company would not have entered into this Agreement or employed the Employee.
The Company and the Employee have independently consulted their respective
counsel and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Company. The Employee's covenants in Sections 7 and 8 are
independent covenants and the existence of any claim by the Employee against the
Company, under this Agreement or otherwise, will not excuse the Employee's
breach of any covenant in Section 7 or 8. If the Employee's employment hereunder
expires or is terminated, this Agreement will continue in full force and effect
as is necessary or appropriate to enforce the covenants and agreements of the
Employee in Sections 7 and 8.

      9.3 Representations and Warranties by the Employee. The Employee
represents and warrants to the Company that the execution and delivery by the
Employee of this Agreement do not, and the performance by the Employee of the
Employee's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Employee; or (b) conflict with, result in the breach of any provisions of or the
termination of, or constitute a


                                       11
<PAGE>

default under, any agreement to which the Employee is a party or by which the
Employee is or may be bound.

      9.4 Obligations Contingent on Performance. The obligations of the Company
hereunder, including its obligation to pay the compensation provided for herein,
are contingent upon the Employee's performance of the Employee's obligations
hereunder.

      9.5 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

      9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement shall
inure to the benefit of, and shall be binding upon, the parties hereto and their
respective successors, assigns, heirs, and legal representatives, including any
entity with which the Company may merge or consolidate or to which all or
substantially all of its assets may be transferred. The duties and covenants of
the Employee under this Agreement, being personal, may not be delegated.

      9.7 Notices. All notices and other communications under this Agreement
must be in writing and will be deemed to have been duly given when (a) delivered
by hand (with written confirmation of receipt), (b) sent by facsimile (with
written confirmation of receipt), provided that a copy is mailed by registered
mail, return receipt requested, or (c) when received by the addressee, if sent
by a nationally recognized overnight delivery service (receipt requested), in
the case of the Company to the attention of the President at the Company's
principal business office and in the case of the Employee to the address or

      6.1 Events of Termination. The Employment Period, the Employee's Salary,
Benefits, and Incentive Compensation, and any and all other rights of the
Employee under this Agreement will terminate (except as otherwise provided in
this Section 6):

            (a)  upon the death of the Employee;

            (b) upon the Disability of the Employee (as defined in Section 6.2)
      immediately upon notice from either party to the other;

            (c) for Cause (as defined in Section 6.3), immediately upon notice
      from the Company to the Employee, or at such later time as such notice may
      specify;

            (d) for Good Reason (as defined in Section 6.4) upon not less than
      thirty days' prior notice from the Employee to the Company; or

            (e) without Cause upon not less than thirty days' notice from the
      Company to the Employee.

      6.2 Definition of "Disability." For purposes of Section 6.1, the Employee
will be deemed to have a "Disability" if, for physical or mental reasons, the
Employee is unable to perform the Employee's duties under this Agreement for 120
consecutive days, or 180 days during any twelve month period, as determined in
accordance with this Section 6.2. The Disability of the Employee will be
determined by a medical doctor selected by written agreement of the Company and
the Employee upon the request of either party by notice to the other. If the
Company and the Employee cannot agree on the selection of a medical doctor, each
of them will select a medical doctor and the two medical doctors will select a
third medical doctor who will determine whether the Employee has a Disability.
The determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Employee must submit to a reasonable number of
examinations by the medical doctor making the determination of Disability under
this Section 6.2, and to other specialists designated by such medical doctor,
and the Employee hereby authorizes the disclosure and release to the Company of
such determination and all supporting medical records. If


                                       5
<PAGE>

the Employee is not legally competent, the Employee's legal guardian or duly
authorized attorney-in-fact will act in the Employee's stead under this Section
6.2 for the purposes of submitting the Employee to the examinations, and
providing the authorization of disclosure, required under this Section 6.2.

      6.3 Definition of "Cause." For purposes of Section 6.1, the term "Cause"
means: (a) the Employee's breach of a material obligation under this Agreement;
(b) the Employee's failure to adhere in any material respect to any written
Company policy if such policy is material to the effective performance by the
Employee of his duties under this Agreement, and if the Employee has been given
a reasonable opportunity to cure his failure to comply within the thirty-day
period preceding termination of this Agreement, provided that if the Employee
cures his failure to comply with such a policy and then fails again to comply
with the same policy, no further opportunity to cure that failure shall be
required; (c) the appropriation (or attempted appropriation) of a material
business opportunity of the Company, including attempting to secure or securing
any personal profit in connection with any transaction entered into on behalf of
the Company (other than through stock options, bonuses and other incentives
provided by the Company to the Employee); (d) the misappropriation (or attempted
misappropriation) of any of the Company's funds or property; or (e) the
conviction of, or the entering of a guilty plea or plea of no contest with
respect to, a felony, or a crime involving moral turpitude, dishonesty, or
fraud.

      6.4 Definition of "Good Reason." For purposes of Section 6.1, the term
"Good Reason" shall mean (a) a substantial reduction in the Employee's duties or
responsibilities, (b) any reduction in Employee's Salary, or (c) relocation of
the Employee's primary workplace to a location that is greater than 35 miles
from the Employee's current workplace, in each case which is not cured within 30
days following the Company's receipt of written notice from the Employee
describing the event constituting Good Reason.

      6.5 Termination Pay. Effective upon the expiration or termination of this
Agreement, the Company will be obligated to pay the Employee (or, in the event
of his death, his designated beneficiary as defined below) only such
compensation as is provided in this Section 6.5. For purposes of this Section
6.5 the Employee's designated beneficiary will be such individual beneficiary or
trust, located at such address, as the Employee may designate by notice to the
Company from time to time or, if the Employee fails to give notice to the
Company of such a beneficiary, the Employee's estate. Notwithstanding the
preceding sentence, the Company will have no duty, in any circumstances, to
attempt to open an estate on behalf of the Employee, to determine whether any
beneficiary designated by the Employee is alive or to ascertain the address of
any such beneficiary, to determine the existence of any trust, to determine
whether any Person purporting to act as the Employee's personal representative
(or the trustee of a trust established by the Employee) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee.

            (a) Termination by the Employee for Good Reason or by the Company
      without Cause. If the Employee terminates this Agreement for Good Reason,
      or if the Company terminates this Agreement other than for Cause (but not
      because of the Disability or death


                                       6
<PAGE>

      of the Employee), or if the Company notifies the Employee in accordance
      with Section 2.2 that this Agreement will not be renewed as of an
      applicable expiration date, the Company will pay the Employee (i) the
      Employee's Salary for the remainder, if any, of the calendar month in
      which such termination is effective and for twelve consecutive calendar
      months thereafter, (ii) the amount of the Employee's targeted incentive
      compensation for the year during which the termination is effective
      (prorated for the period from the beginning of the year until the
      effective date of termination), and (iii) with respect to the
      Post-Employment Period, an additional amount equal to the full amount of
      the Employee's targeted incentive compensation for the year in which the
      termination was effective (such amount to be determined as if the Employee
      had been employed for the entire year and not prorated as described in
      clause (ii) above), payable in equal monthly installments over the
      Post-Employment Period. Notwithstanding the preceding sentence, if the
      Employee obtains other employment prior to the end of the Post-Employment
      Period or any extension thereof, he must promptly give notice thereof to
      the Company, and the payments under this Agreement for any period after
      the Employee obtains other employment will be reduced by the amount of the
      cash compensation received and to be received by the Employee from the
      Employee's other employment for services performed during such period.

            (b) Termination by the Company for Cause. If the Company terminates
      this Agreement for Cause, the Employee will be entitled to receive his
      Salary only through the date such termination is effective.

            (c) Termination upon Disability. If this Agreement is terminated by
      either party as a result of the Employee's Disability, as determined under
      Section 6.2, the Company will pay the Employee his Salary through the
      remainder of the calendar month during which such termination is effective
      and for the lesser of (i) six consecutive months thereafter, or (ii) the
      period until disability insurance benefits commence under any disability
      insurance coverage furnished by the Company to the Employee.

            (d) Termination upon Death. If this Agreement is terminated because
      of the Employee's death, the Employee will be entitled to receive his
      Salary through the end of the calendar month in which his death occurs.

            (e) Benefits. Except as otherwise required by law, the Employee's
      accrual of, or participation in plans providing for, the Benefits will
      cease at the effective date of the termination of this Agreement, and the
      Employee will be entitled to accrued Benefits pursuant to such plans only
      as provided in such plans.

7.    Non-Disclosure Covenant; Employee Inventions

      7.1 Acknowledgments by the Employee. The Employee acknowledges that (a)
during the Employment Period and as a part of his employment, the Employee will
be afforded access to Confidential Information; (b) public disclosure of such
Confidential Information could have an adverse effect on the Company and its
business; (c) because the Employee possesses substantial


                                       7
<PAGE>

technical expertise and skill with respect to the Company's business, the
Company desires to obtain exclusive ownership of each Employee Invention, and
the Company will be at a substantial competitive disadvantage if it fails to
acquire exclusive ownership of each Employee Invention; and (d) the provisions
of this Section 7 are reasonable and necessary to prevent the improper use or
disclosure of Confidential Information and to provide the Company with exclusive
ownership of all Employee Inventions.

      7.2 Agreements of the Employee. In consideration of the compensation and
benefits to be paid or provided to the Employee by the Company under this
Agreement, the Employee covenants as follows:

            (a)  Confidentiality.

                  (i) During and following the Employment Period, the Employee
            will hold in confidence the Confidential Information and will not
            disclose it to any Person except with the specific prior written
            consent of the Company or except as otherwise expressly permitted by
            the terms of this Agreement.

                  (ii) Any trade secrets of the Company will be entitled to all
            of the protections and benefits under the Missouri Uniform Trade
            Secrets Act and any other applicable law. If any information that
            the Company deems to be a trade secret is found by a court of
            competent jurisdiction not to be a trade secret for purposes of this
            Agreement, such information will, nevertheless, be considered
            Confidential Information for purposes of this Agreement. The
            Employee hereby waives any requirement that the Company submit proof
            of the economic value of any trade secret or post a bond or other
            security.

                  (iii) None of the foregoing obligations and restrictions
            applies to any part of the Confidential Information that the
            Employee demonstrates was or became generally available to the
            public other than as a result of a disclosure by the Employee or by
            any other Person bound by a confidentiality obligation to the
            Company in respect of such Confidential Information.

                  (iv) The Employee will not remove from the Company's premises
            (except to the extent such removal is for purposes of the
            performance of the Employee's duties at home or while traveling, or
            except as otherwise specifically authorized by the Company) any
            Company document, record, notebook, plan, model, component, device,
            or computer software or code, whether embodied in a disk or in any
            other form (collectively, the "Proprietary Items"). The Employee
            recognizes that, as between the Company and the Employee, all of the
            Proprietary Items, whether or not developed by the Employee, are the
            exclusive property of the Company. Upon termination of this
            Agreement by either party, or upon the request of the Company during
            the Employment Period, the Employee will return to the Company all
            of the Proprietary Items in the Employee's possession or subject to
            the Employee's control,


                                       8
<PAGE>

            and the Employee shall not retain any copies, abstracts, sketches,
            or other physical embodiment of any of the Proprietary Items.

            (b) Employee Inventions. Each Employee Invention will belong
      exclusively to the Company. The Employee acknowledges that all Employee
      Inventions are works made for hire and are the property of the Company,
      including any copyrights, patents, or other intellectual property rights
      pertaining thereto. If it is determined that any such works are not works
      made for hire, the Employee hereby assigns to the Company all of the
      Employee's right, title, and interest, including all rights of copyright,
      patent, and other intellectual property rights, to or in such Employee
      Inventions. The Employee will promptly:

                  (i) disclose to the Company in writing any Employee Invention;

                  (ii) assign to the Company or to a party designated by the
            Company, at the Company's request and without additional
            compensation, all of the Employee's right to the Employee Invention
            for the United States and all foreign jurisdictions;

                  (iii) execute and deliver to the Company such applications,
            assignments, and other documents as the Company may request in order
            to apply for and obtain patents or other registrations with respect
            to any Employee Invention in the United States and any foreign
            jurisdictions;

                  (iv) sign all other papers necessary to carry out the above
            obligations; and

                  (v) give testimony and render any other assistance in support
            of the Company's rights to any Employee Invention.

      Notwithstanding anything to the contrary herein, provisions otherwise
      requiring the Employee to assign to the Company any invention conceived by
      the Employee shall not apply to an invention for which no equipment,
      supplies, facilities or trade secret information of the Company was used
      and which was developed entirely on the Employee's own time, unless the
      invention relates to the business of the Company or to the Company's
      actual or demonstrably anticipated research or development, or the
      invention results from any work performed by the Employee for the Company.

      7.3 Disputes or Controversies. The Employee recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Employee, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

8.    Non-Competition and Non-Interference


                                       9
<PAGE>

      8.1 Acknowledgments by the Employee. The Employee acknowledges that: (a)
the services to be performed by him under this Agreement are of a special,
unique, unusual, extraordinary, and intellectual character; (b) the Company
competes with other businesses that are or could be located in any part of the
Territory; and (c) the provisions of this Section 8 are reasonable and necessary
to protect the Company's business.

      8.2 Covenants of the Employee. In consideration of the acknowledgments by
the Employee, and in consideration of the compensation and benefits to be paid
or provided to the Employee by the Company, the Employee covenants that he will
not, directly or indirectly:

            (a) during the Employment Period, except in the course of his
      employment hereunder, and during the Post-Employment Period, engage or
      invest in, own, manage, operate, finance, control, or participate in the
      ownership, management, operation, financing, or control of, be employed
      by, associated with, or in any manner connected with, lend the Employee's
      name or any similar name to, lend Employee's credit to or render services
      or advice to, any Competitive Business within the Territory; provided,
      however, that the Employee may purchase or otherwise acquire up to (but
      not more than) one percent of any class of securities of any enterprise
      (but without otherwise participating in the activities of such enterprise)
      if such securities are listed on any national or regional securities
      exchange or have been registered under Section 12(g) of the Securities
      Exchange Act of 1934;

            (b) whether for the Employee's own account or for the account of any
      other Person, at any time during the Employment Period and the
      Post-Employment Period, solicit business of the same or similar type being
      carried on by the Company, from any Person known by the Employee to be a
      customer of the Company, whether or not the Employee had personal contact
      with such Person during and by reason of the Employee's employment with
      the Company;

            (c) whether for the Employee's own account or the account of any
      other Person at any time during the Employment Period and the
      Post-Employment Period, solicit, employ, or otherwise engage as an
      employee, independent contractor, or otherwise, any person who is or was
      an employee of the Company at any time during the Employment Period or in
      any manner induce or attempt to induce any employee of the Company to
      terminate his or her employment with the Company; or at any time during
      the Employment Period and the Post-Employment Period, interfere with the
      Company's relationship with any person, including any person who at any
      time during the Employment Period was an employee, contractor, supplier,
      or customer of the Company;

            (d) at any time during the Employment Period and the Post-Employment
      Period, disparage the Company or any of its shareholders, directors,
      officers, employees, or agents.

      8.3 Divisible Covenants. If any covenant in Section 8.2 is held to be
unreasonable, arbitrary, or against public policy, such covenant will be
considered to be divisible with respect to scope, time, and geographic area, and
such lesser scope, time, or geographic area, or all of them, as


                                       10
<PAGE>

a court of competent jurisdiction may determine to be reasonable, not arbitrary,
and not against public policy, will be effective, binding, and enforceable
against the Employee.

      8.4 Extension of Covenants. The period of time applicable to any covenant
in Section 8.2 will be extended by the duration of any violation by the Employee
of such covenant.

      8.5 Notices. The Employee will, while the covenants under Section 8.2 are
in effect, give notice to the Company, within ten days after accepting any other
employment, of the identity of the Employee's new employer. The Company may
notify such new employer that the Employee is bound by this Agreement and, at
the Company's election, furnish such new employer with a copy of this Agreement
or relevant portions thereof.

9.    General Provisions

      9.1 Injunctive Relief and Additional Remedy. The Employee acknowledges
that the injury that would be suffered by the Company as a result of a breach of
the provisions of this Agreement (including any provision of Sections 7 and 8)
would be irreparable and that an award of monetary damages to the Company for
such a breach would be an inadequate remedy. Consequently, the Company will have
the right, in addition to any other rights it may have, to obtain injunctive
relief to restrain any breach or threatened breach or otherwise to specifically
enforce any provision of this Agreement, and the Company will not be obligated
to post bond or other security in seeking such relief. Without limiting the
Company's rights under this Section 9 or any other remedies of the Company, if
the Employee breaches any of the provisions of Section 7 or 8, the Company will
have the right to cease making any payments otherwise due to the Employee under
this Agreement.

      9.2 Covenants of Sections 7 and 8 are Essential and Independent Covenants.
The covenants by the Employee in Sections 7 and 8 are essential elements of this
Agreement, and without the Employee's agreement to comply with such covenants,
the Company would not have entered into this Agreement or employed the Employee.
The Company and the Employee have independently consulted their respective
counsel and have been advised in all respects concerning the reasonableness and
propriety of such covenants, with specific regard to the nature of the business
conducted by the Company. The Employee's covenants in Sections 7 and 8 are
independent covenants and the existence of any claim by the Employee against the
Company, under this Agreement or otherwise, will not excuse the Employee's
breach of any covenant in Section 7 or 8. If the Employee's employment hereunder
expires or is terminated, this Agreement will continue in full force and effect
as is necessary or appropriate to enforce the covenants and agreements of the
Employee in Sections 7 and 8.

      9.3 Representations and Warranties by the Employee. The Employee
represents and warrants to the Company that the execution and delivery by the
Employee of this Agreement do not, and the performance by the Employee of the
Employee's obligations hereunder will not, with or without the giving of notice
or the passage of time, or both: (a) violate any judgment, writ, injunction, or
order of any court, arbitrator, or governmental agency applicable to the
Employee; or (b) conflict with, result in the breach of any provisions of or the
termination of, or constitute a


                                       11
<PAGE>

default under, any agreement to which the Employee is a party or by which the
Employee is or may be bound.

      9.4 Obligations Contingent on Performance. The obligations of the Company
hereunder, including its obligation to pay the compensation provided for herein,
are contingent upon the Employee's performance of the Employee's obligations
hereunder.

      9.5 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by either
party in exercising any right, power, or privilege under this Agreement will
operate as a waiver of such right, power, or privilege, and no single or partial
exercise of any such right, power, or privilege will preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege. To the maximum extent permitted by applicable law,
(a) no claim or right arising out of this Agreement can be discharged by one
party, in whole or in part, by a waiver or renunciation of the claim or right
unless in writing signed by the other party; (b) no waiver that may be given by
a party will be applicable except in the specific instance for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any obligation of such party or of the right of the party giving such notice
or demand to take further action without notice or demand as provided in this
Agreement.

      9.6 Binding Effect; Delegation of Duties Prohibited. This Agreement shall
inure to the benefit of, and shall be binding upon, the parties hereto and their
respective successors, assigns, heirs, and legal representatives, including any
entity with which the Company may merge or consolidate or to which all or
substantially all of its assets may be transferred. The duties and covenants of
the Employee under this Agreement, being personal, may not be delegated.

      9.7 Notices. All notices and other communications under this Agreement
must be in writing and will be deemed to have been duly given when (a) delivered
by hand (with written confirmation of receipt), (b) sent by facsimile (with
written confirmation of receipt), provided that a copy is mailed by registered
mail, return receipt requested, or (c) when received by the addressee, if sent
by a nationally recognized overnight delivery service (receipt requested), in
the case of the Company to the attention of the President at the Company's
principal business office and in the case of the Employee to the address or
facsimile number set forth below (or to such other address or facsimile number
as the Employee may designate by notice to the Company):

agreement between the parties with respect to its subject matter and supersedes
