                       THE MANAGEMENT NETWORK GROUP, INC.

     We provide management consulting services to the global telecommunications
industry, including communications service providers, technology companies and
financial services firms. We provide a comprehensive range of services,
including strategic, management and operational advice, that enable our clients
to meet the challenges of today's competitive and dynamic telecommunications
environment, including the growing demand for electronic business, known as
e-business, infrastructure. Since our inception in 1990, we have performed
services for over 170 clients. For example, our top two clients for the first
nine months of 1999 were: Williams Communications Group and diAx.

     Our industry-focused services help our broad range of clients capitalize on
the vast opportunities brought about by a rapidly changing telecommunications
market. Our complete range of solutions include:

     - strategic assessments;

     - design and evaluation of telecommunications infrastructure;

     - operational support and process improvement; and

     - system evaluation, selection and implementation advice.

     The sophisticated services we provide make extensive use of the proprietary
methodologies we have developed, ensuring the high quality and timeliness of our
services. Our solutions enable our clients to compete more effectively by
aligning their service offerings with their chosen market strategies. In
addition, our solutions allow them to offer their services cost-effectively and
accelerate the introduction of new technologies, while improving overall
customer satisfaction and retention, all of which are critical components of
their profitability.

     We provide our services through highly experienced consultants who average
over ten years of industry experience. In 1998 and 1997, our President and Chief
Executive Officer was named by Phone+ magazine, a trade publication, to its
annual list of the most influential people in competitive long distance
telecommunications. In both years he was the highest-ranking non-carrier
executive selected for this list. We believe our clients value the extensive
expertise and industry knowledge our consultants provide, enabling us to develop
relationships with many of our clients, who in many cases rely on our advice and
services to make critical strategic and business decisions.

     Our key growth initiatives include:

     - combining our telecommunications and e-business expertise to help our
       clients successfully develop and deploy the underlying infrastructure to
       support the internet and to meet their growing e-business requirements;

     - capitalizing on our competitive telecommunications experience to expand
       globally to serve our clients' growing global needs as overseas markets
       continue to face increasing deregulation and competition;

     - further enhancing our long-term client relationships to allow us to
       jointly plan future projects and develop large, multi-year engagements;

     - building our brand through several marketing initiatives; and

     - extending our business model by enhancing our business processes that can
       be duplicated worldwide.

                SUMMARY HISTORICAL AND PRO FORMA FINANCIAL DATA
                                  (UNAUDITED)

     The following summary financial information should be read in conjunction
with our consolidated financial statements and their related notes and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" included in this prospectus. Listed below is our statement of
operations data for fiscal years 1995 through 1998 and for the nine months ended
October 3, 1999 and October 2, 1998, and our balance sheet data as of October 3,
1999. The results for the interim periods are not necessarily indicative of the
results for the full fiscal year or any future period. Interim results reflect
all adjustments, which are in the opinion of management, necessary to a fair
statement of these results.

     To calculate the "Pro Forma As Adjusted Statement of Operations Data" for
fiscal year 1998 and the nine months ended October 3, 1998 and October 2, 1999,
we have assumed the following occurred as of the first day of fiscal 1998:

     - our leveraged recapitalization, which was actually completed in February
       1998;

     - our conversion of tax status from a subchapter "S" corporation to a
       subchapter "C" corporation which occurred at the time of
       recapitalization; and


     - the sale of 4,615,000 shares of common stock in the offering at an
       assumed initial public offering price of $15.00 per share, after
       deducting the underwriting discounts and estimated offering expenses, and
       the application of the net proceeds of the offering to repay all of our
       bank debt.


     To calculate the pro forma as adjusted balance sheet data, we have assumed
this offering and the application of the net proceeds from this offering, as
described above, occurred on October 2, 1999.

     Beginning with fiscal 1998, we switched to a four week -- four week -- five
week quarterly accounting system in which each quarter is 13 weeks long and ends
on a Saturday. As a result of this change, our fiscal year end changed from
December 31 to the Saturday which is 13 weeks from the end of the third fiscal
quarter. The words "fiscal year" in this prospectus refer to the fiscal year
most closely coinciding with the related calendar year. Our 1998 fiscal year
therefore ended on January 2, 1999. When we refer to the "nine month period for
1998" and to "nine month period for 1999" in this prospectus, we mean nine month
period ended on October 3, 1998 and October 2, 1999, respectively.

(1) Before February 12, 1998, we were a subchapter "S" corporation and,
    accordingly, federal and state income taxes were paid at the stockholder
    level only. Upon consummation of the February 1998 leveraged
    recapitalization, we terminated our subchapter "S" corporation status and,
    accordingly, became subject to federal and state income taxes. The pro forma
    as adjusted statement of operations data reflects adjustments to historical
    net income as if we had not elected subchapter "S" corporation status for
    federal and state income tax purposes.

(2) Pro forma as adjusted weighted average common shares outstanding assumes
    that the following occurred at the beginning of the period indicated:

     - our leveraged recapitalization, which actually occurred in February 1998;
       and

     - the issuance of 4,615,000 shares of common stock issuable in this
       offering.

(3) Pro forma as adjusted assumes the issuance of 4,615,000 shares of common
    stock issuable in this offering at October 2, 1999.

                                  RISK FACTORS

     You should carefully consider the following risk factors and all other
information contained in this prospectus before purchasing our common stock.
Investing in our common stock involves a high degree of risk.

WE FOCUS EXCLUSIVELY ON SERVING THE TELECOMMUNICATIONS INDUSTRY AND THEREFORE
CHANGES IN THIS INDUSTRY COULD REDUCE OUR CUSTOMER BASE OR CAUSE CUSTOMERS TO
USE INTERNAL RESOURCES

     We currently derive all of our revenues from consulting engagements within
the telecommunications industry. Much of our recent growth has arisen from
business opportunities presented by industry trends that include:

     - deregulation;

     - increased competition;

     - technological advances;

     - the growth of e-business; and

     - the convergence of service offerings.

     If these trends change, the demand for telecommunications consulting work
will likely decrease. In addition, the telecommunications industry is in a
period of consolidation, which could reduce our client base, eliminate future
opportunities or create conflicts of interest among our clients. Additionally,
current and future economic pressures in the industry may cause
telecommunications companies to use internal resources in lieu of outside
consultants. As a result, our customer base and our revenues may decline.

WE ARE DEPENDENT ON A LIMITED NUMBER OF LARGE CUSTOMERS FOR A MAJOR PORTION OF
OUR REVENUES, AND THE LOSS OF A MAJOR CUSTOMER COULD REDUCE OUR REVENUES AND
HARM OUR BUSINESS

     We derive a significant portion of our revenues from a relatively limited
number of clients. For example, during 1997 and 1998, revenues from our ten most
significant clients accounted for approximately 78.4% and 76.0% of our revenues,
respectively. In the first nine months of 1999, Williams Communications Group
and diAx accounted for 41.1% and 13.6% of our revenues, respectively. The
services required by any one client may be affected by industry consolidation,
technological developments, economic slowdown or internal budget constraints. As
a result, the volume of work performed for specific clients varies from period
to period, and a major client in one period may not use our services in a
subsequent period.

     Our services are often sold under short-term engagements and most clients
can reduce or cancel their contracts with little or no penalty or notice. Our
operating results may suffer if we are unable to rapidly deploy consultants if a
client defers, modifies or cancels a project. Consequently, you should not
predict or anticipate our future revenue based on the number of clients we have
or the number and scope of our existing engagements.

OUR REVENUES AND OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY FROM QUARTER TO
QUARTER, AND FLUCTUATIONS IN OUR OPERATING RESULTS COULD CAUSE OUR STOCK PRICE
TO DECLINE

     Our revenue and operating results may vary significantly from
quarter-to-quarter due to a number of factors. In future quarters, our operating
results may be below the expectations of public market analysts or investors,
and the price of our common stock may decline. Factors that could cause
quarterly fluctuations include:

     - the beginning and ending of significant contracts during a quarter;

     - the size and scope of assignments;

                                        7
<PAGE>   9

     - consultant turnover, utilization rates and billing rates;

     - the loss of key consultants, which could cause clients to end their
       relationships with us;

     - the ability of clients to terminate engagements without penalty;

     - fluctuations in demand for our services resulting from budget cuts,
       project delays, cyclical downturns or similar events;

     - clients' decisions to divert resources to other projects, including Year
       2000 remediation work, which may limit clients' resources that would
       otherwise be allocated to projects we could provide;

     - reductions in the prices of services offered by our competitors;

     - fluctuations in the telecommunications market and economic conditions;

     - seasonality during the summer, vacation and holiday periods; and

     - fluctuations in the value of foreign currencies versus the U.S. dollar.

     Because a significant portion of our expenses are relatively fixed, a
variation in the number of client assignments or the timing of the initiation or
the completion of client assignments may cause significant variations in
operating results from quarter to quarter and could result in losses. To the
extent the addition of consultant employees is not followed by corresponding
increases in revenues, we would incur additional expenses that would not be
matched by corresponding revenues. Therefore, our profitability would decline
and we could potentially experience losses. In addition, our stock price would
likely decline.

WE MUST CONTINUE TO ATTRACT AND RETAIN QUALITY CONSULTANTS, AND OUR INABILITY TO
DO SO WOULD IMPAIR OUR ABILITY TO SERVICE EXISTING ENGAGEMENTS OR UNDERTAKE NEW
ENGAGEMENTS, RESULTING IN A DECLINE IN OUR REVENUES AND INCOME

     We must attract a significant number of new consultants to implement our
growth plans. The number of potential consultants that meet our hiring criteria
is relatively small, and we face significant competition for these consultants
from our direct competitors and others in the telecommunications industry.
Competition for these consultants may result in significant increases in our
costs to retain the consultants, which could reduce our margins and our
profitability. In addition, we will need to attract consultants in international
locations, principally Europe, to support our international growth plans. We
have limited experience in recruiting internationally, and we may not be able to
do so. Our inability to recruit new consultants and retain existing consultants
could impair our ability to service existing engagements or undertake new
engagements. If we are unable to attract and retain consultants, our revenues
and our profitability would decline.

THE MARKET IN WHICH WE COMPETE IS INTENSELY COMPETITIVE AND ACTIONS BY
COMPETITORS COULD RENDER OUR SERVICES LESS COMPETITIVE CAUSING OUR REVENUES AND
INCOME TO DECLINE

     The market for consulting services to telecommunications companies is
intensely competitive, highly fragmented and subject to rapid change. Our
competitors include general management consulting firms, the consulting
practices of "Big Five" accounting firms, most of which have practice groups
focused on the telecommunications industry and local or regional firms
specializing in telecommunications services. Some of these competitors have also
formed strategic alliances with telecommunications and technology companies
serving the industry. We also compete with internal resources of our clients.
Our competitors include:

     - American Management Systems;

     - Andersen Consulting;

     - Booz-Allen & Hamilton;
                                        8
<PAGE>   10

     - The Boston Consulting Group;

     - Cap Gemini;

     - KPMG Peat Marwick; and

     - PricewaterhouseCoopers.

     Many information technology consulting firms also maintain significant
practice groups devoted to the telecommunications industry. Many of these
companies have a national and international presence and may have greater
personnel, financial, technical and marketing resources. We cannot assure you
that we will compete successfully with our existing competitors or with any new
competitors.

     We also believe our ability to compete depends on a number of factors
outside of our control, including:

     - the prices at which others offer competitive services, including
       aggressive price competition and discounting on individual engagements;

     - the ability and willingness of our competitors to finance customers'
       projects on favorable terms;

     - the ability of our competitors to undertake more extensive marketing
       campaigns than we can;

     - the extent, if any, to which our competitors develop proprietary tools
       that improve their ability to compete with us;

     - the ability of our customers to perform the services themselves; and

     - the extent of our competitors' responsiveness to customer needs.

     We may not be able to compete effectively on these or other factors. If we
are unable to compete effectively, our market position, and therefore our
revenues and profitability, would decline.

WE HAVE EXPERIENCED SIGNIFICANT GROWTH IN OUR BUSINESS IN RECENT PERIODS, AND IF
WE ARE UNABLE TO MANAGE THIS GROWTH, OUR OPERATIONAL INFRASTRUCTURE MAY NOT BE
ABLE TO SUPPORT OUR GROWTH

     We are currently experiencing a period of rapid growth that may strain our
managerial and operational resources. To support our growth, our organizational
infrastructure must grow accordingly.

     To manage the expected growth of our operations and personnel, we must:

     - improve existing and implement new operational, financial and management
       controls, reporting systems and procedures; and

     - maintain and expand our financial management information systems.

     If we fail to address these issues, our operational infrastructure may be
insufficient to support our levels of business activity. In this event, we could
experience disruptions in our business and declining revenues or profitability.

IF WE DO NOT EFFECTIVELY MANAGE THE CONVERSION OF INDEPENDENT CONTRACTORS TO
EMPLOYEES, WE COULD INCUR UNANTICIPATED COSTS WHICH WOULD HARM OUR FINANCIAL
PERFORMANCE

     We are planning to offer contingent employee or full-time employee status
to certain of our independent contractors. As we convert independent contractors
to consultant employees, we will incur additional fixed costs for each such
employee that we do not incur when we retain an independent contractor. To
effectively manage these additional fixed costs, we will need to continuously
improve utilization management and minimize unbilled employee time. In addition,
                                        9
<PAGE>   11

this change may cause other disruptions to our business. If we fail to
effectively manage this transition, we could incur additional costs due to
underutilization of full-time employees as well as other unanticipated costs.

IF WE DO NOT CONTINUALLY ENHANCE OUR SERVICES TO MEET THE CHANGING NEEDS OF OUR
CUSTOMERS, WE MAY LOSE FUTURE BUSINESS TO OUR COMPETITORS

     We believe that our future success will depend upon our ability to enhance
our existing services and to introduce new services to meet the requirements of
our customers in a rapidly developing and evolving market. Our present or future
services may not satisfy the needs of the telecommunications market. If we are
unable to anticipate or respond adequately to customer needs, we may lose
business and our financial performance will suffer.

OUR PLANS FOR INTERNATIONAL EXPANSION MAY NOT SUCCEED, WHICH WOULD HARM OUR
REVENUES AND PROFITABILITY

     Our future revenues depend to a large extent on expansion into
international markets. Our future international operations might not succeed for
a number of reasons, including:

     - difficulties in staffing and managing foreign operations;

     - seasonal reductions in business activity;

     - fluctuations in currency exchange rates or imposition of currency
       exchange controls;

     - competition from local and foreign-based consulting companies;

     - issues relating to uncertainties of laws and enforcement relating to the
       protection of intellectual property;

     - unexpected changes in trading policies and regulatory requirements;

     - legal uncertainties inherent in transnational operations such as export
       and import regulations, tariffs and other trade barriers;

     - taxation issues;

     - operational issues such as longer customer payment cycles and greater
       difficulties in collecting accounts receivable;

     - language and cultural differences;

     - general political and economic trends; and

     - expropriations of assets, including bank accounts, intellectual property
       and physical assets by foreign governments.

     Accordingly, we may not be able to successfully execute our business plan
in foreign markets. If we are unable to achieve anticipated levels of revenues
from our international operations, our revenues and profitability would decline.

IF OUR INTERNATIONAL BUSINESS VOLUMES INCREASE, WE WILL BE EXPOSED TO GREATER
FOREIGN CURRENCY EXCHANGE RISKS, WHICH COULD RESULT IN INCREASED EXPENSES AND
DECLINING PROFITABILITY

     The percentage of our revenues comprised of international engagements
increased significantly in the first nine months of 1999 and may continue to
increase. Some of our international engagements are denominated in the local
currency of our clients. Expenses that we incur in delivering these services,
consisting primarily of consultant compensation, are typically denominated in
U.S. dollars. To the extent that the value of a currency in which our billings
are denominated decreases in relation to the U.S. dollar or another currency in
which our expenses are denominated, our operating results and financial
condition could be harmed. We may hedge our
                                       10
<PAGE>   12

foreign currency exposure from time to time, but we cannot assure you that any
hedging will be effective.

WE EXPECT THE GROWTH OF OUR TMNG.COM BUSINESS TO DRIVE FUTURE REVENUES AND IF
THIS DOES NOT HAPPEN OUR REVENUES AND PROFITABILITY WOULD DECLINE

     A significant part of our future growth is dependent upon our ability to
grow our TMNG.com business which is focused on providing consulting services to
help telecommunications companies build the infrastructure, systems and
processes needed to support e-business. To support this growth, we must develop
a base of consultants with internet-based skills. The personnel and skill sets
required for our TMNG.com services are different from those used in our
traditional lines of business. The personnel that we need to support this
business may not be widely available, and we may encounter unforeseen
difficulties in recruiting needed personnel for the TMNG.com initiative. In
addition, we may be unable to develop methodologies to address the unique needs
of internet-based companies due to our relative lack of experience in this
market. Additionally, the continuously evolving nature of the internet makes it
very difficult to establish e-business expertise. If we fail to adequately
develop our internet and e-business skills, we may not be able to capitalize on
the growth opportunities presented by these sectors, and our competitive
position, revenues and profitability would decline.

OUR TMNG.COM BUSINESS IS DEPENDENT ON CONTINUED GROWTH, USE AND ACCEPTANCE OF
THE INTERNET AND E-BUSINESS

     Our success in providing e-business related consulting services depends in
part on widespread acceptance and use of the internet as a way to conduct
business. The internet and e-business may not become a viable long-term
commercial marketplace due to potentially inadequate development of the
necessary network infrastructure or delayed development of enabling technologies
and performance improvements. Our business would be harmed if:

     - use of the internet and other online services does not increase or
       increases at a slower pace than expected or on-line services do not
       become viable marketplaces;

     - the infrastructure for the internet and other online services does not
       effectively support future expansion of e-business; or

     - concerns over security and privacy inhibit the growth of the internet.

The failure of the internet to continue to grow would inhibit the demand for our
TMNG.com consulting services and our revenues and financial performance.

WE ARE DEPENDENT ON A LIMITED NUMBER OF KEY PERSONNEL, AND THE LOSS OF THESE
INDIVIDUALS COULD HARM OUR COMPETITIVE POSITION AND FINANCIAL PERFORMANCE

     Our business consists primarily of the delivery of professional services
and, accordingly, our success depends upon the efforts, abilities, business
generation capabilities and project execution of our executive officers and key
consultants. Our success is also dependent upon the managerial, operational and
administrative skills of our executive officers, particularly Richard Nespola,
our President and Chief Executive Officer. The loss of any executive officer or
key consultant or group of consultants, or the failure of these individuals to
generate business or otherwise perform at or above historical levels could
result in a loss of customers or revenues, and could therefore harm our
financial performance.

IF WE FAIL TO PERFORM EFFECTIVELY ON PROJECT ENGAGEMENTS, OUR REPUTATION, AND
THEREFORE OUR COMPETITIVE POSITION AND FINANCIAL PERFORMANCE COULD BE HARMED

     Many of our engagements come from existing clients or from referrals by
existing clients. Therefore, our growth is dependent on our reputation and on
client satisfaction. The failure to
                                       11
<PAGE>   13

perform services that meet a client's expectations may damage our reputation and
harm our ability to attract new business. Damage to our reputation arising from
client dissatisfaction could therefore harm our financial performance.

IF WE FAIL TO DEVELOP LONG-TERM RELATIONSHIPS WITH CUSTOMERS, OUR SUCCESS WOULD
BE JEOPARDIZED

     A substantial majority of our business is derived from repeat customers.
Our future success depends to a significant extent on our ability to develop
long-term relationships with successful telecommunications providers who will
give us new and repeat business. We may be unable to develop new customer
relationships and our new or existing customers may be unsuccessful. Our
inability to build long-term customer relations would result in declines in our
revenues and profitability.

A LARGE NUMBER OF OUR PERSONNEL ARE CLASSIFIED AS INDEPENDENT CONTRACTORS FOR
TAX AND EMPLOYMENT LAW PURPOSES, AND IF THESE PERSONNEL WERE TO BE RECLASSIFIED
AS EMPLOYEES, WE COULD BE SUBJECT TO BACK TAXES, INTEREST, PENALTIES AND OTHER
LEGAL CLAIMS

     We provide the substantial majority of our consulting services through
independent contractors and, therefore, do not pay federal or state employment
taxes or withhold income taxes for such persons. Further, we generally do not
include these independent contractors in our benefit plans. In the future, the
IRS and state authorities may challenge the status of consultants as independent
contractors. Independent contractors may also initiate proceedings to seek
reclassification as employees under state law. In either case, if persons
engaged by us as independent contractors are determined to be employees by the
IRS or any state taxation department, we would be required to pay applicable
federal and state employment taxes and withhold income taxes with respect to
such persons and could become liable for amounts required to be paid or withheld
in prior periods along with penalties. In addition, we could be required to
include such persons in our benefit plans retroactively and going forward. As of
October 2, 1999, approximately 115 consultants were working on engagements for
us as independent contractors. In addition, at least another 100 individuals
have worked for us as independent contracts since January 1, 1998. Any challenge
by the IRS or state authorities or individuals resulting in a determination that
a substantial number of such persons are employees could subject us to liability
for back taxes, interest and penalties, which would harm our profitability.

WE COULD BE SUBJECT TO CLAIMS FOR PROFESSIONAL LIABILITY, WHICH COULD HARM OUR
FINANCIAL PERFORMANCE

     As a provider of professional services, we face the risk of liability
claims. A liability claim brought against us could harm our business. We may
also be subject to claims by our clients for the actions of our consultants and
employees arising from damages to clients' business or otherwise.

     In particular, we are currently a defendant in litigation brought by the
bankruptcy trustee of one of our former clients. This litigation seeks to
recover $320,000 in consulting fees paid by the former client and also seeks to
recover at least $1.85 million for breach of contract, breach of fiduciary
duties and negligence. For additional information regarding this proceeding,
please see "Business -- Legal Proceedings."

THE MARKET PRICE OF OUR COMMON STOCK MAY BE VOLATILE, AND OUR INVESTORS MAY
EXPERIENCE INVESTMENT LOSSES

     The market price of our common stock may be volatile. Our stock price could
decline or fluctuate in response to a variety of factors, including:

     - variations in our quarterly operating results;

     - announcements of technological innovations that render our talent
       outdated;

                                       12
<PAGE>   14

     - introduction of new services or new pricing policies by us or our
       competitors;

     - trends in the telecommunications industry;

     - acquisitions or strategic alliances by us or others in our industry;

     - failure to achieve financial analysts' or other estimates of our results
       of operations for any fiscal period;

     - changes in estimates of our performance or recommendations by financial
       analysts; and

     - market conditions in the telecommunications industry and the economy as a
       whole.

     In addition, the stock market experiences significant price and volume
fluctuations. These fluctuations particularly affect the market prices of the
securities of many high technology companies. These broad market fluctuations
could harm the market price of our common stock.

WE MAY MAKE ACQUISITIONS, WHICH ENTAIL RISKS THAT COULD HARM OUR FINANCIAL
PERFORMANCE OR STOCK PRICE

     As part of our business strategy, we may make acquisitions. Currently, we
do not have any planned or pending acquisitions. Any future acquisition would be
accompanied by the risks commonly encountered in acquisitions. These risks
include:

     - the difficulty associated with assimilating the personnel and operations
       of acquired companies;

     - the potential disruption of our existing business; and

     - adverse effects on our financial statements, including one-time
       write-offs, ongoing charges for amortization of goodwill and assumption
       of liabilities of acquired businesses.

     If we make acquisitions and any of these problems materialize, these
acquisitions could negatively affect our operations, profitability and financial
operations.

OUR INABILITY TO PROTECT OUR INTELLECTUAL PROPERTY COULD HARM OUR COMPETITIVE
POSITION AND OUR FINANCIAL PERFORMANCE

     Despite our efforts to protect our proprietary rights from unauthorized use
or disclosure, parties, including former employees or consultants of ours, may
attempt to disclose, obtain or use our solutions or technologies. The steps we
have taken may not prevent misappropriation of our solutions or technologies,
particularly in foreign countries where laws or law enforcement practices may
not protect our proprietary rights as fully as in the United States.
Unauthorized disclosure of our proprietary information could make our solutions
and methodologies available to others and harm our competitive position.

     Intellectual property claims brought against us, regardless of their merit,
could result in costly litigation and the diversion of our financial resources
and technical and management personnel. Further, if such claims are proven
valid, through litigation or otherwise, we may be required to change our
trademarks and pay financial damages, which could harm our profitability and
financial performance.

PRINCIPAL STOCKHOLDERS, EXECUTIVE OFFICERS AND DIRECTORS WILL RETAIN SUBSTANTIAL
CONTROL OVER US AFTER THE OFFERING AND MAY MAKE DECISIONS THAT ARE NOT IN THE
BEST INTEREST OF OTHER STOCKHOLDERS

     Upon completion of this offering, our executive officers, directors and
stockholders owning more than five percent of our outstanding common stock (and
their affiliates) will, in the aggregate, own approximately 83.2% of our
outstanding common stock. As a result, such persons, acting together, will have
the ability to substantially influence all matters submitted to the stockholders
for approval (including the election and removal of directors and any merger,
consolidation or sale of all or substantially all of our assets) and to control
our management and affairs. Accordingly, concentration of ownership of our
common stock may have the effect of delaying, deferring or
                                       13
<PAGE>   15

preventing a change in control, impeding a merger, consolidation, takeover or
other business combination involving us or discouraging a potential acquirer
from making a tender offer or otherwise attempting to obtain control of us, even
if such a transaction would be beneficial to other stockholders.

THERE HAS BEEN NO PRIOR PUBLIC MARKET FOR OUR COMMON STOCK, AND THE PRICE OF OUR
COMMON STOCK MAY DECLINE

     Our common stock has never been sold in a public market. An active trading
market for our common stock may not develop or be sustained upon the completion
of this offering. In addition, the initial offering price may not be indicative
of the prices that will prevail in the public market after the offering, and the
market price of the common stock could fall below the initial public offering
price.

THE SIGNIFICANT NUMBER OF SHARES OF COMMON STOCK THAT WILL BE ELIGIBLE FOR SALE
IN THE NEAR FUTURE MAY HARM THE MARKET PRICE OF OUR COMMON STOCK

     Sales of a substantial number of shares of our common stock in the public
market following this offering could harm the market price for our common stock.
This may prevent stockholders from reselling their shares at or above the price
at which they purchased their shares. Upon expiration of 180-day lockup
agreements that our stockholders have entered into with the underwriters or us,
14,745,115 shares of our common stock will become eligible for immediate sale.
This amount represents approximately 54.1% of the shares of our common stock
outstanding upon completion of this offering. For additional detail regarding
shares eligible for sale, please see "Shares Eligible for Future Sale."

WE USED TO BE TAXED UNDER SUBCHAPTER "S" OF THE INTERNAL REVENUE CODE AND CLAIMS
OF TAXING AUTHORITIES RELATED TO OUR PRIOR SUBCHAPTER "S" CORPORATION STATUS
COULD HARM US

     From 1993 through 1998, we were taxed as a "pass-through" entity under
subchapter "S" of the Internal Revenue Code. Since February 1998, we have been
taxed under subchapter "C" of the Internal Revenue Code, which is applicable to
most corporations and treats the corporation as an entity that is separate and
distinct from its stockholders. If our tax returns for the years in which we
were a subchapter "S" corporation were to be audited by the Internal Revenue
Service or another taxing authority and an adverse determination was made during
the audit, we could be obligated to pay back taxes, interest and penalties. The
stockholders of our predecessor entity agreed, at the time we acquired our
predecessor, to indemnify us against negative tax consequences arising from our
prior "S" corporation status. This indemnity is secured by escrowed funds in an
escrow that terminates in February 2001. Accordingly, this indemnity may not be
sufficient to cover claims made by the IRS or other taxing authorities, and any
such claims could result in additional costs and harm our financial performance.

INVESTORS IN THIS OFFERING WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION


     If you purchase shares of our common stock, you will incur immediate and
substantial dilution of $13.11 in pro forma net tangible book value per share.
If other security holders exercise options or warrants to purchase our common
stock, you will suffer further dilution.


WE MAY SEEK TO RAISE ADDITIONAL FUNDS, AND ADDITIONAL FUNDING MAY BE DILUTIVE TO
STOCKHOLDERS OR IMPOSE OPERATIONAL RESTRICTIONS

     Any additional equity financing may be dilutive to our stockholders and
debt financing, if available, may involve restrictive covenants, which may limit
our operating flexibility with respect to certain business matters. If
additional funds are raised through the issuance of equity securities, the
percentage ownership of our stockholders will be reduced. These stockholders may
experience

                                       14
<PAGE>   16

additional dilution in net book value per share and any additional equity
securities may have rights, preferences and privileges senior to those of the
holders of our common stock.

WE DO NOT ANTICIPATE PAYING DIVIDENDS ON OUR COMMON STOCK IN THE FORESEEABLE
FUTURE

     We currently intend to retain all available funds for use in the operation
and expansion of our business and do not anticipate paying any cash dividends in
the foreseeable future. Contractual restrictions currently prohibit us from
paying cash dividends.

ANTI-TAKEOVER PROVISIONS AND OUR RIGHT TO ISSUE PREFERRED STOCK COULD MAKE A
THIRD PARTY ACQUISITION OF US DIFFICULT

     Our certificate of incorporation and bylaws and anti-takeover provisions of
Delaware law could make it more difficult for a third party to acquire control
of us, even if a change in control would be beneficial to stockholders. In
addition, our bylaws provide for a classified board, with board members serving
staggered three-year terms. The Delaware anti-takeover provisions and the
existence of a classified board could make it more difficult for a third party
to acquire us.

IF OUR INTERNAL SYSTEMS OR THE INTERNAL SYSTEMS OF OUR CUSTOMERS OR SUPPLIERS
ARE NOT YEAR 2000 COMPLIANT, WE COULD EXPERIENCE DISRUPTIONS IN COMMUNICATIONS
SERVICE AND LOST REVENUES

     We cannot assure you that our computer systems and software products do not
contain undetected errors or defects associated with Year 2000 data functions,
nor can we assure you that the software components we have acquired from third
parties will be Year 2000 compliant. This failure to be Year 2000 compliant
could result in system failures, delays or miscalculations. Computer systems and
software that have not been developed or enhanced recently may need to be
upgraded or replaced to comply with Year 2000 requirements. If we discover any
Year 2000 errors or defects in our internal systems, we could incur substantial
costs in making repairs. The resulting disruption of our operations could harm
our business.

     Furthermore, the Internet operations of many of our customers and suppliers
may be affected by Year 2000 complications. The failure of our customers or
suppliers to ensure that their systems are Year 2000 compliant could harm our
customers and suppliers, resulting in our inability to obtain necessary data
communication and telecommunication capacity. In addition, our customers may
encounter Year 2000 problems which cause them to divert resources from projects
we are or could potentially be engaged in order for them to solve their Year
2000 problems. If diversions of this nature occur, we could experience lost
revenues or cancellation or delay of engagements, which would harm our revenues
and profitability.

                           FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements that involve risks and
uncertainties, which may include statements about our:

     - business strategy;

     - financial performance and trends affecting our business; and

     - plans, objectives, expectations and intentions contained in this
       prospectus that are not historical facts.

     When used in this prospectus, the words "expects," "anticipates,"
"intends," "plans," "believes," "seeks," "estimates" and similar expressions are
generally intended to identify forward-looking statements. In addition, this
prospectus includes statistical data that comes from information published by
independent sources, including International Data Corporation (IDC). Because
these forward-looking statements involve risks and uncertainties, actual results
could differ materially from those expressed or implied by these forward-looking
statements for a number of reasons, including those discussed under "Risk
Factors" and elsewhere in this prospectus.

                                USE OF PROCEEDS


     We estimate that we will receive proceeds of $63.4 million from the sale of
the 4,615,000 shares of common stock we are offering assuming a public offering
price of $15.00 per share and after deducting the underwriting discount and our
estimated offering expenses.


     We intend to use approximately $23.3 million of the proceeds of the
offering for repayment of indebtedness. We plan to use the remainder of the
proceeds for general corporate purposes, including working capital. We may also
use some of the proceeds to acquire other complementary businesses, although we
have no current plans relating to any of these transactions. Pending these uses,
the net proceeds of this offering will be invested in short-term, investment
grade, interest-bearing securities.

     The indebtedness to be repaid with the proceeds of this offering consists
of two term loans, with principal balances of $11.0 million and $12.0 million at
October 2, 1999, and any outstanding borrowings under our $5.0 million revolving
credit facility. As of October 2, 1999, total borrowings of $317,000 were
outstanding under our revolving credit facility. The term loans and revolving
credit facility are secured by a pledge of substantially all of our assets. We
pay quarterly interest on the term loan that has an $11.0 million principal
balance at the London Interbank Offered Rate, or LIBOR, plus 2.75%. We pay
quarterly interest on the other term loan at LIBOR plus 3.00%. As of October 2,
1999, LIBOR equaled 5.40% and the interest rates on our term loans were 8.15%
and 8.40%, respectively. As of October 2, 1999, the interest rate on our
revolving credit facility was based on the prime rate plus 1.25%, which equalled
9.50%. Both of the term loans and the revolving credit facility mature on
December 31, 2003. The terms of our indebtedness require us to maintain
specified financial ratios and observe additional restrictive covenants. As of
October 2, 1999, we were in compliance with these ratios and covenants.

                                DIVIDEND POLICY

     We currently expect to retain our future earnings, if any, for use in the
operation and expansion of our business and do not anticipate paying any cash
dividends in the foreseeable future. Covenants in our bank credit agreements
prohibit the payment of cash dividends.

       underwriting discount and estimated offering expenses and repayment of
       debt with the net proceeds of this offering.

                                    DILUTION

     Our net tangible book value as of October 2, 1999 was approximately ($13.0)
million, or approximately ($.57) per share of common stock. Net tangible book
value per share represents the amount of tangible assets less total liabilities,
divided by the shares of common stock outstanding as of October 2, 1999.


     Dilution in net tangible book value per share represents the difference
between the amount per share paid by purchasers of shares of our common stock in
this offering and the pro forma as adjusted net tangible book value per share of
our common stock immediately after the offering. After giving effect to our sale
of 4,615,000 shares of common stock in this offering at an assumed public
offering price of $15.00 per share and after deducting the underwriting discount
and estimated offering expenses, our pro forma as adjusted net tangible book
value as of October 2, 1999 would have been approximately $51.3 million, or
$1.89 per share. This represents an immediate increase in pro forma as adjusted
net tangible book value of $2.46 per share to existing stockholders and an
immediate dilution in pro forma as adjusted net tangible book value of $13.11
per share to purchasers of common stock in this offering.

     The foregoing computations exclude 1,695,250 shares of common stock subject
to options issued at a weighted average exercise price of $1.68 per share
granted under our 1998 equity incentive plan. These computations also exclude
500,000 shares of common stock subject to an outstanding warrant issued to
Williams Communications Group at an exercise price of $2.00 per share.

     To the extent these options and the warrant are exercised, there would be
additional dilution to investors purchasing shares in this offering.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA

     The following unaudited pro forma condensed consolidated financial data has
been prepared by our management from our consolidated financial statements and
the notes to those statements included elsewhere in this prospectus. We believe
that the accounting treatment used to prepare the pro forma data provides a
reasonable basis on which to present this unaudited pro forma condensed
consolidated financial data. The unaudited pro forma condensed consolidated
statements of operations for fiscal 1998, and the nine months ended October 2,
1999, reflects adjustments as if our leveraged recapitalization (which occurred
in February, 1998) and this offering had occurred on January 1, 1998. The
unaudited pro forma as adjusted condensed consolidated balance sheet as of
October 2, 1999 gives effect to this offering and the use of proceeds as stated
in "Use of Proceeds" as if it had occurred on October 2, 1999.

     We are providing the unaudited pro forma condensed consolidated financial
data for informational purposes only. The pro forma condensed financial data
shown below may not necessarily be indicative of either our financial position
or the results of our operations which would have occurred had the
recapitalization and this offering actually occurred on the dates described
above, nor are they necessarily indicative of the results of operations for any
future period. The unaudited pro forma condensed consolidated financial data and
accompanying notes should be read in conjunction with our financial statements
and the notes to those statements included elsewhere in this prospectus.

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

     The following "Management's Discussion and Analysis of Financial Condition
and Results of Operations" should be read in conjunction with our consolidated
financial statements and related notes appearing at the end of this prospectus.

OVERVIEW

     We are a global management consulting firm that specializes in serving the
telecommunications industry. We provide comprehensive services that enable our
clients to meet the challenges of today's competitive and dynamic
telecommunications environment, including the growing demand for Internet
infrastructure and e-business solutions. Our clients include communications
service providers, technology companies and the investment firms that support
the telecommunications industry. We capitalize on our industry expertise and
proprietary methodologies to provide strategic, management and operational
support to our clients.

     From 1995 through 1998, our revenues grew at a compounded annual growth
rate of 63.8%. Revenue for the nine months ended October 2, 1999 increased by
72.2% over the nine months ended October 3, 1998. The principal factors driving
revenue growth have been increased competition in the telecommunications
industry resulting from deregulation, new technology and convergence of voice
and data services. The combined factors create new opportunities and challenges
for telecommunications companies, resulting in a need for independent expertise
by both incumbent carriers and new market entrants alike.

     Beginning with fiscal year 1998, we switched to a four week -- four
week -- five week quarterly accounting system in which each quarter is 13 weeks
and ends on a Saturday. As a result of this change, our fiscal year end changed
from being December 31 to being the Saturday which is 13 weeks from the end of
the third fiscal quarter. Our 1998 fiscal year therefore ended on January 2,
1999. The words "fiscal year" in this prospectus refer to the fiscal year most
closely coinciding with the related calendar year. When we refer to the "nine
month period for 1998" and the "nine month period for 1999" in this prospectus,
we mean the nine month period ending on October 3, 1998 and October 2, 1999,
respectively.

     Sources of Revenue and Revenue Recognition Policy. Our revenues consist of
consulting fees for professional services and related expense reimbursements.
Substantially all of our consulting services are contracted on a time and
materials basis not to exceed a negotiated contract price. We recognize
substantially all revenues in the period in which the service is performed. We
generally begin a client relationship with a short-term engagement utilizing a
few consultants. Our sales strategy focuses on building long-term relationships
with both new and existing clients to gain additional engagements within
existing accounts and referrals for new clients. We also use strategic alliances
with other companies to sell our services and anticipate that we will continue
to do so in the future. Because we are a consulting company, we experience
fluctuations in revenues derived from our clients during the course of a project
lifecycle. As a result, the volume of work performed for specific clients varies
from period to period and a major client from one period may not use our
services in another period. In addition, our clients generally may end their
engagements with little or no penalty or notice. If a client engagement ends
earlier than we expect, we must re-deploy professional service personnel as any
resulting unbillable time could harm our margins.

     Through fiscal year 1998, most of our engagements were in North America. We
have experienced growth in our international consulting engagements, primarily
in Europe. International revenues during the first nine months of fiscal year
1999 grew to 26.7% of total revenue from 16.4% in the comparable period of the
prior year. We expect that international revenues will continue to represent an
increasing percentage of total revenues. Our knowledge and focus on trends
impacting markets abroad enable us to provide the expert advice needed by
international clients competing in newly deregulated markets and by U.S.
companies seeking to expand their global reach. We

                                       25
<PAGE>   27

continue to expand our geographic presence in key locations based on industry
demand and our clients' needs and opportunities.

     We are planning to introduce our TMNG.com services, which will be directed
at assisting communications service providers in building the infrastructure to
support e-business. We are recruiting additional consultants to support this
business and designing our proprietary methodologies to focus on e-business,
including our TMNG e-Lexicon. While we expect to incur substantial costs in
connection with the development of TMNG.com, we also expect that a significant
portion of our long-term service revenues will be attributable to our TMNG.com
service offerings. Should these revenues fall short of our expectations for any
reason, our margins could be harmed.

     Customer concentration. While we have a large number of customers, we also
depend on a few key customers for a significant portion of our revenues. In
fiscal year 1998, 42.5% of our revenues came from Williams Communications Group,
Bell Atlantic and e.spire Communications, with services to each accounting for
more than ten percent of our revenues. For the first nine months of fiscal year
1999, 54.7% of our revenues came from Williams Communications Group and diAx
with each accounting for more than ten percent of our revenues. We generally
negotiate discounted pricing for large projects with long-term customers.
Because our clients typically engage our services on a project basis, their
needs for our services vary substantially from period to period. While we are
seeking to diversify our customer base and expand the portion of our revenues
which is derived from service through various channels, we anticipate that our
operating results will continue to depend on volume services to a relatively
small number of communication service providers and technology vendors.

     Cost of Services. Cost of services consists primarily of fees paid to
independent contractors and client-related compensation for consultants who are
employees as well as equity related non-cash charges we incur in connection with
the grants of equity securities primarily to consultants. Employee compensation
includes certain unbillable time, training, vacation time, benefits and payroll
taxes. Our annual gross margins have ranged from 41.0% to 45.0% during the
period from 1995 to 1998. Margins are primarily impacted by:

     - the type of consulting services provided;

     - the size of service contracts and negotiated volume discounts;

     - changes in our pricing policies and those of our competitors;

     - utilization rates of consultants and independent contractors; and

     - employee and independent contractor costs associated with a competitive
       labor market.

     In addition, gross margins may be impacted by a change we are beginning to
implement in our consultants' status. Currently, the majority of our consulting
engagements are staffed by independent contractors. To improve our ability to
attract and retain personnel, we plan to offer certain current consultants
either regular full-time employment or contingent employment. Contingent
employees are eligible for stock options and generally receive company-paid
medical insurance, vacation and other employee benefits. However, instead of
receiving a regular salary, contingent employees will be compensated only for
time spent serving on consulting projects for customers or requested assistance
on internal projects, including updating our toolsets. We believe our contingent
employment model is unique and provides our consultants with employee benefits,
greater flexibility for personal time and organizational support while providing
us greater flexibility in managing utilization rates than if we hired these
consultants as full-time employees. In addition, as we increase the full-time
employee portion of our consultant base, it becomes increasingly important for
us to manage utilization rates. If we are unable to manage utilization rates,
our gross margins may be negatively impacted because of the additional fixed
costs associated with full-time employees.

                                       26
<PAGE>   28

     Operating Expenses. Operating expenses include selling, general and
administrative expenses as well as equity related non-cash charges we incur in
connection with the grants of equity security primarily to partners, principals
and certain senior executives. Sales and marketing expenses consist primarily of
personnel and related costs for our direct client marketing efforts and
marketing staff. We primarily use a relationship sales model in which our
partners, principals and consultants generate revenues. We take these revenue
generating activities into account when determining these individuals' quarterly
bonus compensation, which is generally recorded as sales and marketing expenses.
Other expenditures include costs associated with marketing materials, trade
shows and advertising. To increase market awareness of our company, we intend to
continue to expand our direct and indirect sales efforts substantially, both
domestically and internationally. We will continue investment in sales and
marketing by adding to our senior executive team to support targeted marketing
programs, promoting recognition of our senior executives through published
articles and trade show presentations, and advertisement of new service
offerings, including a substantial portion for TMNG.com. We expect our sales and
marketing expenses to increase in the future.

     General and administrative expenses consist primarily of salaries for
employees engaged primarily in executive and support functions as well as
expenses for corporate infrastructure. We plan to maintain our flexibility in
hiring a mix of full time employees, full time contingent employees and
independent subject matter experts to help us manage costs. We do not expect to
invest heavily in facilities because we plan to link our consultants by
electronic communication, enabling our consultants to work off-site using
internet communication capabilities known as our eRooms. We are also investing
heavily in updating our toolsets and developing new ones. A substantial portion
of our recruiting and toolset development expenses will be incurred in
connection with the development of our TMNG.com service line. Our development
expenditures are expensed when incurred. We expect our selling, general and
administrative expenses to increase in absolute dollars and as a percentage of
revenues, due in part to the expenses we expect to incur in connection with the
development of TMNG.com.

     Equity related charges. In connection with the grant of certain stock
options to employees during the nine month period ended October 2, 1999 and
fiscal year ended 1998, we recorded unearned compensation of $6.1 million and
$305,000, respectively, representing the difference between the deemed value of
common stock for accounting purposes and the exercise price of these options at
the date of grant. Unearned compensation is presented as a reduction of
stockholders' equity (deficit) and is amortized over the vesting period of the
applicable options. We expensed $1.2 million of unearned compensation during the
nine month period ended October 2, 1999. In addition, $261,000 and $1.1 million
of compensation expense was recorded for stock options granted to independent
contractors and other non-employees during fiscal year ended 1998 and the nine
month period ended October 2, 1999. Compensation expense of $441,000 for
employee stock bonus awards was also recorded during the nine months ended
October 2, 1999. This employee and non-employee compensation expense relates to
stock options awarded to individuals providing consulting service and operating
activities. In connection with the issuance to Williams Communications Group of
a warrant to purchase 500,000 shares of our common stock in October 1999, we
expect to recognize approximately $5.2 million as future equity related charges
in operations. This amount represents the difference between the deemed value of
the common stock, issuable upon exercise of the warrant, and the exercise price
of the warrant at the date of grant.

     Recapitalization. From our inception through February 12, 1998, the date of
our leveraged recapitalization, our pre-recapitalization stockholders, Richard
P. Nespola, Micky K. Woo, Alan H. Staples and Ralph R. Peck conducted operations
through several loosely affiliated entities. On February 12, 1998, we effected a
leveraged recapitalization with Behrman Capital II, L.P. and affiliated venture
funds in which the Behrman Capital funds acquired shares of common stock for
$20.0 million. At that time, we also borrowed $24.0 million in term loans and
obtained a $5.0 million revolving credit facility from Chase Manhattan Bank and
a syndicate of lenders established by Chase Manhattan Bank. The proceeds from
the investment by Behrman Capital and the term loans

                                       27
<PAGE>   29

were used principally to fund the redemption of approximately 60% of the common
stock owned by Messrs. Nespola, Woo, Peck and Staples for an aggregate
redemption price of approximately $38.7 million. In connection with the
recapitalization, we made distributions to the stockholders of approximately
$4.7 million, representing accumulated equity in our company and resulting in
negative stockholders' equity of $21.6 million. We accounted for the transaction
using the leveraged recapitalization accounting convention. As a result of the
recapitalization, we incurred non-recurring recapitalization costs totaling
approximately $3.1 million related to offering costs.

     Prior to the recapitalization, we compensated Messrs. Woo, Peck and Staples
for oversight and strategic advice principally through management fees paid to
affiliates owned by them, along with fees for independent contractor services
provided to our clients through these affiliated entities. At the time of the
recapitalization, we ceased making payments of management fees and entered into
an employment agreement with each of Messrs. Nespola, Woo, Peck and Staples.

     From 1993 through February 12, 1998, we elected to be treated as a
subchapter "S" corporation for tax purposes. During that period, all of our
outstanding common stock was owned by Messrs. Nespola, Woo, Peck and Staples.
Upon consummation of the recapitalization, we terminated our subchapter "S"
corporation election and became obligated to pay federal and state income taxes
as a subchapter "C" corporation. We estimate our effective income tax rate will
be approximately 40% of taxable income in fiscal year 1999.

COMPARISON OF NINE MONTHS ENDED OCTOBER 2, 1999 AND OCTOBER 3, 1998

     Revenues. Revenues increased 72.2% to $37.0 million for the nine month
period for 1999 from $21.5 million for the nine month period for 1998. The
increase was primarily attributable to a net

                                       28
<PAGE>   30

increase in consulting services. The increase in consulting services was due
primarily to a significant increase in services provided to a major customer,
which was offset in part by negotiated volume discounts. Revenues for the first
nine months of 1999 included revenues from services provided to one large
customer, which accounted for 41.1% of our revenues during that period. Our
international revenue expanded to 26.7% of revenues in the nine month period for
1999 compared to 16.4% for the nine month period for 1998, primarily due to an
increase in European business.

     Cost of Services

     Direct Cost of Services. Direct cost of services increased to $19.2 million
for the nine month period for 1999 from $11.6 million for the nine month period
for 1998. Direct cost of services as a percent of revenue decreased from 54.1%
for the nine month period for 1998 to 51.9% for the nine month period for 1999.
Direct gross margins improved because our consultant mix changed to include more
employees in fiscal year 1999 compared to fiscal year 1998. A greater portion of
full-time employees at a relatively constant utilization rate tends to improve
gross margins because of their overall lower fixed salary compared to the higher
variable costs we pay our independent contractors. The margin improvement
provided by increasing the full-time employee base was slightly offset by
discounted customer pricing associated with large engagements.

     Equity Related Charges. We recorded non-cash stock based compensation
charges of $1.8 million and $14,000 in the nine month periods for 1999 and 1998,
respectively, in connection with the issuance of stock options to our employees
and non-employee consultants. These charges reduced gross margin by 4.8% in
1999.

     Operating Expenses

     Selling, General and Administrative Expense. Selling, general and
administrative expenses increased to $7.5 million for the nine month period for
1999 from $4.0 million for the nine month period for 1998. Selling, general and
administrative expense as a percentage of revenue increased to 20.2% for the
nine month period for 1999 from 18.7% for the nine month period for 1998. We
incurred an increase in marketing costs primarily as a result of an increase in
sales bonuses associated with implementation of a revised incentive program for
our consultants and increased revenues for the nine month period for 1999. We
incurred an increase in selling, general and administrative expense primarily
due to the personnel and facility costs associated with opening a new corporate
office in the third quarter of fiscal year 1998 and increased administrative
staffing to manage and support the growth of the organization. We also hired
managing directors to lead our European and Canadian subsidiaries at the
beginning of fiscal year 1999. In addition, we established reserves of $160,000
for a potential claim brought against us by a trustee in bankruptcy for a former
client.

     Equity Related Charges. We recorded non-cash stock based compensation
charges of $946,000 and $1,000 in the nine month period for 1999 and 1998,
respectively, in connection with the issuance of stock options to our partners,
principals and certain senior executives and non-employee directors. These
charges increased operating expenses as a percentage of revenue by 2.6%.

     Interest Expense. Interest expense increased to $1.7 million for the nine
month period for 1999, compared to $1.5 million for the nine month period for
1998. Interest expense primarily relates to $24.0 million of borrowings under
our term loans incurred in connection with our recapitalization in February 1998
and borrowings on our revolving credit facility. The increase in interest
expense was due to nine months of expense incurred for the nine month period for
1999 compared to eight months of expense for the nine month period for 1998.

     Other (Income) Expense. Other income for the nine month period for 1998
primarily represents the recovery of $92,000 related to an employee advance
previously reserved.

                                       29
<PAGE>   31

     Income Taxes. Provision for income taxes for the nine month period for 1999
as a percentage of pretax income was 41.5% compared to 57.9% for the nine month
period for 1998. The 57.9% effective tax rate for the nine month period 1998
exceeded the statutory federal income tax rate primarily due to the
establishment of net deferred taxes upon conversion to a "C" corporation on
February 12, 1998 in connection with the leveraged recapitalization and state
income taxes. These increases in income tax expense were partially reduced by
the exclusion of net income prior to February 12, 1998, representing "S"
corporation net income. Prior to the conversion to a "C" corporation on February
12, 1998, we did not report tax expense as an "S" corporation.

COMPARISON OF FISCAL YEARS 1998 AND 1997

     Revenues. Revenues increased 59.1% to $32.1 million in fiscal year 1998
from $20.2 million in fiscal year 1997. The increase in revenues was due
primarily to the commencement of several major new engagements during 1998.
Higher billing rates, which resulted from a reduction in volume discounts in
fiscal 1998 as compared to fiscal 1997, also contributed to the increase. The
revenues in fiscal year 1997 included revenues from services provided to one
large customer, which accounted for 39.3% of revenues in that year, at a
negotiated volume discount. International revenues in fiscal year 1998 were
16.2% of revenues, primarily from Canada, and in fiscal year 1997 were 0.8% of
revenues.

     Cost of Services

     Direct Cost of Services. Direct cost of services increased to $17.4 million
in fiscal year 1998 from $11.4 million in fiscal year 1997. As a percentage of
revenues, direct cost of services decreased to 54.2% in fiscal year 1998 from
56.4% in fiscal year 1997. The gross margin improvement resulted primarily from
a reduction in business from our two largest customers in fiscal year 1997 at
negotiated volume discounts. In addition, our gross margins improved because our
consultant mix changed to include more employees in fiscal year 1998 compared to
fiscal year 1997.

     Equity Related Charges. We recorded $239,000 non-cash stock based
compensation charges in fiscal year 1998 in connection with the issuance of
stock options to our consultants. These charges reduced gross margin in this
period by 0.7%.

     Operating Expenses

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased 87.7% to $6.2 million in fiscal year 1998 from
$3.3 million in fiscal year 1997. As a percentage of revenues, selling, general
and administrative expenses increased to 19.2% in fiscal year 1998 from 16.3% in
fiscal year 1997. Employee costs increased in fiscal year 1998 due to the larger
role our principals had in generating sales and the compensation expense
associated with those responsibilities. In addition, expenses increased in
fiscal year 1998 due to infrastructure investment. We opened our new corporate
office in September 1998, and hired five management and administrative employees
late in the year. We installed management information systems in 1998, including
our financial reporting and project costing systems. In fiscal year 1998, we
enhanced our marketing materials, expanded our marketing efforts in Europe and
promoted our brand. We also expanded efforts to enhance our TMNG Lexicon and
TMNG CLEC Planner toolsets in fiscal year 1998.

     Interest Expense. Interest expense increased to $2.1 million in fiscal year
1998 from $30,000 in fiscal year 1997. Interest expense in fiscal year 1998
related primarily to two term loans in an aggregate principal amount of $24.0
million entered into in connection with our leveraged recapitalization. In
fiscal year 1997, interest expense related to notes payable to several of our
stockholders.

     Other (Income) Expense. Other income in the fiscal year 1998 primarily
represents the recovery of $92,000 related to an employee advance previously
reserved in fiscal year 1997.

                                       30
<PAGE>   32

     Income Taxes. Provision for income taxes was $3.3 million in fiscal year
1998. The 51.9% effective tax rate in fiscal year 1998 exceeded the statutory
federal income tax rate primarily due to the establishment of net deferred taxes
upon conversion to a subchapter "C" corporation, and state income taxes. These
increases in provision for income taxes were partially reduced by the exclusion
of net income prior to February 12, 1998, representing "S" corporation net
income. Prior to the conversion to a "C" corporation on February 12, 1998, we
did not report tax expense as an "S" corporation.

     Net Income. Net income decreased to $3.0 million in fiscal year 1998 from
$5.5 million in fiscal year 1997. In 1997, the Company was a subchapter "S"
corporation and did not report tax expense. Income before provision for income
taxes increased to $6.3 million in fiscal 1998 from $5.5 million in fiscal year
1997.

COMPARISON OF FISCAL YEARS 1997 AND 1996

     Revenues. Revenues increased 16.8% to $20.2 million in fiscal year 1997
from $17.3 million in fiscal year 1996, resulting from a net increase in
consulting services offset in part by a volume discount negotiated by a large
customer in fiscal year 1997, which customer represented 39.3% of revenues.

     Cost of Services. Cost of services increased to $11.4 million in fiscal
year 1997 from $9.6 million in fiscal year 1996. As a percentage of sales, cost
of services was 56.4% and 55.8% in fiscal years 1997 and 1996, respectively.
Gross margins decreased in fiscal year 1997 compared to fiscal year 1996 due
primarily to negotiated volume discounts provided to one large customer in
fiscal year 1997.

     Operating Expenses

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased to $3.3 million in fiscal year 1997 from $2.8
million in fiscal year 1996. As a percentage of revenues, selling, general and
administrative expenses increased to 16.3% in fiscal year 1997 from 16.2% in
1996. Selling, general and administrative expenses remained relatively constant
as there were no significant changes in operations with the exception of
increased marketing activities.

     Interest Expense. Interest expense decreased to $30,000 in fiscal year 1997
from $136,000 in fiscal year 1996. The decrease in interest expense resulted
from the payment of notes payable to stockholders.

     In the past, we have experienced seasonal fluctuations in revenue in the
fourth quarter due primarily to the fewer number of business days because of the
holiday periods occurring in that quarter. We may in the future experience
fluctuations in revenue in the fourth quarter as well as summer and other
vacation periods as we expand internationally.

LIQUIDITY AND CAPITAL RESOURCES

     We have historically funded our business through cash provided by
operations. The principal use of cash subsequent to the leveraged
recapitalization was debt service incurred in connection with the leveraged
recapitalization. Prior to the leveraged recapitalization, the principal use of
cash was to fund distribution of earnings to our stockholders. At October 2,
1999, we had cash of approximately 1.5 million. Although we believe that the net
proceeds of this offering together with cash generated from operations will be
sufficient to meet our anticipated cash requirements, including scheduled debt
repayments and anticipated capital expenditures, for at least the next 12
months, we may in the future require additional funds to meet our cash
requirements and successfully execute on our business model beyond that 12-month
period. We may be required to raise additional funds through sales of equity or
debt securities or seek additional financing from financial institutions. We
cannot assure you that that financing will be available to us on favorable terms
or, if obtained, will be sufficient for our needs.

     Cash provided by operating activities for the nine month period for 1999
and 1998 and for the fiscal years ended 1998, 1997 and 1996 was approximately
$3.0 million, $1.6 million, $2.0 million, $4.3 million and $4.3 million,
respectively. Cash provided by operating activities for the nine month period
for 1999 was generated primarily by net income, as adjusted primarily by
increases in deferred tax assets and receivables aggregating $4.7 million,
offset by an increase in accrued liabilities of $2.0 million and stock option
and bonus share compensation of $2.7 million.

     Cash provided by operating activities for the nine month period for 1998
was generated by net income and increases in accounts payable, accrued
liabilities, deferred tax liabilities and income taxes payable aggregating $4.3
million, adjusted primarily by increases in accounts receivable of $4.6 million.
Cash provided by operating activities in fiscal year 1998 was generated by net
income and an increase in accounts payable and accrued liabilities of $1.8
million, adjusted primarily by an increase in accounts receivable of $3.9
million. Cash provided by operating activities in fiscal year 1997 was generated
by net income as adjusted by an increase in accounts receivable of $1.4 million.
Cash provided by operating activities in fiscal year 1996 was generated by net
income, adjusted primarily by an increase in accounts receivable of $700,000.

     Cash used in investing activities for the nine month period for 1999 and
1998 and for fiscal year 1998 was $400,000, $300,000, and $500,000,
respectively. Cash was used for the purchase of property and equipment, and we
expect to continue to invest in fixtures and equipment in the ordinary course of
business, including expenditures in connection with the purchase of sales and
staff tracking software and the upgrading of computer equipment and networking
infrastructure.

     Cash used in financing activities for the nine month period for 1999 and
1998 and for the fiscal years 1998, 1997 and 1996 was $2.1 million, $1.0
million, $800,000, $4.3 million, and $4.3 million, respectively. Cash used in
financing activities for the nine month period for 1999 was due primarily to the
repayment of long-term debt and net repayments of borrowing under the credit
facility aggregating $2.7 million. Cash used in financing activities for the
nine month period for 1998 and fiscal year 1998 was due primarily to the impact
of net borrowings of $25.9 million in connection with the leveraged
recapitalization and net issuance and redemption of common stock of $21.8
million, an increase in deferred financing costs of $600,000, and the payment of
final subchapter "S" corporation distributions of $4.7 million. Cash used in
financing activities in fiscal 1997 and 1996 was due primarily to distributions
to stockholders of $4.0 million and $4.7 million, respectively.

INTEREST RATE AND CURRENCY EXCHANGE RATE RISK

     We have variable interest rate exposure under our senior bank debt
agreements, which we mitigate by utilizing derivative financial instruments. We
do not use derivative financial instruments for speculative or trading purposes.

                                       33
<PAGE>   35

     We entered into an interest rate cap agreement on March 13, 1998, covering
a notional amount of $12.0 million under one of our term loans, to reduce our
exposure to market risks from changes in interest rates. We plan to retire the
outstanding senior bank debt and the interest cap agreement in connection with
this offering. Under the interest rate cap agreement, if during any period the
floating interest rate on our senior bank debt exceeds the cap rate under the
agreement, which is currently 8.187%, our bank will pay us the difference
between the two rates for the period.

     We anticipate that revenues from international engagements will increase as
a percentage of our revenues. We may enter into consulting engagements that are
denominated in foreign currencies. To the extent that the value of a currency in
which our billings are denominated decreases in relation to the U.S. dollar or
another currency in which our expenses are denominated, our expenses would
increase and the profitability of the engagement would decline. We may hedge our
foreign currency exposure from time to time but our hedging activities may not
be effective.

RECENT ACCOUNTING PRONOUNCEMENTS

     In March 1998, the American Institute of Certified Public Accountants, or
AICPA, issued Statement of Position, or SOP, No. 98-1, Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use. SOP No. 98-1
requires entities to capitalize certain costs related to internal-use software
once certain criteria have been met. We adopted SOP No. 98-1 effective January
3, 1999 and it did not have a significant effect on our financial position or
results of operations.

     In April 1998, the AICPA issued SOP No. 98-5, Reporting on the Costs of
Start-Up Activities. SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, all start-up costs
that were capitalized in the past must be written off when SOP No. 98-5 is
adopted. We adopted SOP No. 98-5 effective January 1, 1999 and it did not have a
significant effect on our financial position or results of operations.

     In June 1998, the Financial Accounting Standards Board issued FAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. FAS No. 133
establishes methods for derivative financial instruments and hedging activities
related to those instruments, as well as other hedging activities, We expect
that the adoption of FAS No. 133 will not have a significant effect on our
financial position or results of operations. FAS No. 137 has deferred the
effective date of FAS 133 to fiscal years beginning after June 15, 2000.

YEAR 2000 READINESS

     The "Year 2000" issue is a general term used to describe the various
problems that may result from the improper processing of dates and
date-sensitive calculations by computers and other machinery as the year 2000 is
approached and reached. These problems arise from hardware and software unable
to distinguish dates in the "2000's" from dates in the "1900's" and from other
sources such as the use of special codes and conventions in software that make
use of a date field. We recognize the need to ensure our operations will not be
adversely affected by Year 2000 software failures.

     We have reviewed our internal management information and other critical
business systems to identify any Year 2000 problems. All such systems were
vendor supplied with no significant modifications. Consequently, we have
communicated with the external vendors that supply us with material software and
information systems and with significant suppliers to determine their Year 2000
readiness. Based on our vendors' representations, we believe that the
third-party hardware and software we use is Year 2000 compliant although we have
not performed any operational tests on these systems.

     To date, we have not incurred any material costs directly associated with
Year 2000 compliance efforts. As discussed above, we do not expect the total
cost of Year 2000 problems to be material to

                                       34
<PAGE>   36

our business, financial condition and operating results. During the months prior
to the century change, however we will continue to evaluate any new versions of
software and information systems provided by third parties and any new
infrastructure systems that we may acquire, to determine whether they are Year
2000 compliant. Despite our current assessment, we may not identify and correct
all significant Year 2000 problems on a timely basis. If the representations
made by our various vendors regarding Year 2000 compliance are inaccurate,
additional Year 2000 compliance efforts may involve significant time and expense
and unremediated problems could harm our business. We currently have no
contingency plans to address the risk.

     In addition, the software and systems of our clients, third-party service
companies and others outside of our control may not be Year 2000 ready. Our
analysis of their Year 2000 readiness has been limited to reviewing periodic
updates contained in publicly available documents in which these clients,
principally telecommunications service providers, describe the status of their
readiness. Our clients' descriptions generally contain significant cautionary
language regarding ultimate Year 2000 outcomes. If our third-party service
providers, clients and others are not Year 2000 ready, a systemic failure beyond
our control could result, including prolonged internet, telecommunications or
general electrical failure. This type of failure would significantly interfere
with our ability to provide our services to our clients. If a prolonged failure
of this type occurred, our business would be harmed.

                                    BUSINESS

OVERVIEW

     We provide management consulting services to the global telecommunications
industry. Our clients include:

     - communications service providers;

     - technology companies; and

     - financial services firms.

     We provide comprehensive services that address imminent client needs and
enable our clients to meet the challenges of today's competitive and dynamic
telecommunications environment. Present challenges include the ever-growing
demand on companies to conduct e-business and facilitate commercial
relationships over the internet. Our highly experienced consultants, who average
over ten years of telecommunications industry experience, enable us to use our
industry expertise and proprietary methodologies to provide strategic,
management and operational support to our clients.

     We serve clients in all major regions of the U.S., in key European markets
and in several other international locations.

     We are the successor to a telecommunications consulting company founded in
1990 by Richard P. Nespola, our President and Chief Executive Officer. Several
additional shareholders were added in 1993. We then underwent a leveraged
recapitalization transaction in 1998. We were incorporated in Kansas in 1993 and
reincorporated in Delaware in September 1999.

INDUSTRY BACKGROUND

     CONSULTING SERVICES

     The demand for consulting services has been increasing in the last decade,
a trend that is expected to continue. International Data Corporation, also known
as IDC, projects that worldwide consulting services will increase from $52.4
billion in 1998 to $102.8 billion in 2003, a compound annual growth rate of
14.4%. The growth of the use of the internet is further spurring this demand as
companies are seeking to improve their business practices through internet-based
communications solutions. Forrester Research, Inc., projects that the worldwide
internet professional services will grow from $2.4 billion in 1997 to $32.8
billion in 2002, a compound annual growth rate of 68.7%.

     As with other businesses, telecommunications companies are increasingly
turning to external consulting firms to help them improve their business
processes and enter new markets as rapidly as possible. Factors such as
deregulation and privatization, mergers and acquisitions within the industry,
and the pace of technological change are driving these companies to seek the
advice of outside experts and supplement the need for additional professionals
to implement their strategies. IDC projects that communications information
technology consulting services will increase from $3.2 billion in 1998 to $6.9
billion in 2003, a compound annual growth rate of 16.5%.

     TELECOMMUNICATIONS

     Other market dynamics that are contributing to an increased need for
consulting services in the global telecommunications industry include:

     - deregulation, which began in the U.S. with the breakup of AT&T and
       continued with the Telecommunications Act of 1996 and is accelerating in
       Europe and other international markets;

                                       36
<PAGE>   38

     - the growth of the internet and e-business, which increases the demand for
       telecommunications capacity and places further pressure on incumbent and
       emerging communications service providers to make substantial changes in
       the way they do business to support this growth;

     - convergence among the different types of services being provided by a
       single telecommunications company;

     - the influx of new entrants and increasing competition due to deregulation
       and an increasing demand for telecommunications services; and

     - technological advances, which have significantly increased the volume of
       traffic that can be carried over telecommunications networks and have
       lowered transmission costs.

Deregulation

     The U.S. telecommunications market reaps the benefits of deregulation,
which began in 1984 and continued with the federal Telecommunications Act of
1996. Deregulation has brought about the liberalization of the
telecommunications market in the United States. Deregulation created new
opportunities not only for the incumbent communications carriers but also for a
vast array of new market entrants. Deregulation has created substantially
greater competition in the industry, resulting in:

     - significantly reduced rates;

     - vastly improved and new technologies; and

     - even more competition.

     More recently, deregulation has accelerated internationally. In 1997, the
World Trade Organization Telecommunications Accord was adopted. This treaty has
contributed to deregulation initiatives in Europe, Asia and Latin America.

Explosion of e-Business

     The growth of the internet is a global phenomenon fundamentally changing
the nature of the telecommunications industry. Web user growth, coupled with the
growth of new types of on-line and e-business services has driven the emergence
of new service providers such as internet service providers, on-line
communities, internet telephony providers and others. In addition, traditional
telecommunications carriers have entered the on-line market, providing internet
connections and e-business services to businesses and consumers. The growth of
the internet and e-business raises critical strategic and operational issues
that telecommunications companies will need to address, including:

     - complex integration issues associated with merging old and new network
       technologies;

     - unprecedented demand for capacity, which companies must meet while
       simultaneously assuring service quality; and

     - operational changes needed to support e-business initiatives in a secure
       environment, including seamless web-based customer care, on-line bill
       presentment and payment, dynamic product introduction and management.

Convergence and Complexity

     In the past, communications service providers typically specialized or
offered a single product or a limited set of products to their customers. Such
specialization required the customer to purchase its entire package of
communications needs from multiple providers. Deregulation has enabled companies
to enter previously closed markets and offer multiple services through one stop

                                       37
<PAGE>   39

shopping. Companies now seek to meet all of the customer's communications needs.
In addition, advances in technology accelerated convergence in the services
provided on the underlying communications network. For example, the ability to
transport telephone calls over the internet will enable service providers to
efficiently integrate voice and data services on a single network.

     Consolidation among key players has also contributed to convergence as
major companies seek to broaden their service offerings through acquisitions.
Companies must integrate multiple corporate infrastructures, networks,
operations and processes.

Influx of New Entrants

     The increased demand for services has led not only to additional offerings
by the established players, but also to new entrants to the market. Industry
sources estimate that there are now over 3,000 new providers of voice and data
telecommunications services in the U.S. We expect this competitive trend to
continue to migrate overseas as global deregulation spreads. New market entrants
seek to gain market share from incumbent service providers, who in turn are
striving to change their business models to adapt to the newer, more competitive
industry environment. As a result, core telecommunications services are becoming
increasingly commoditized, making superior customer service and satisfaction, as
well as efficient and cost effective back office systems, key competitive
elements.

Rapid Technological Advances

     The telecommunications industry is characterized by rapid technological
advances. Unprecedented levels of transmission capacity, both in terms of the
size and number of packets of data that can be transmitted, now exist due to the
advent of new technologies for voice and data transmission.

     Additionally, improvements in fiber optics and other transmission
technologies have increased the number of calls a single fiber can carry from
8,000 in 1985 to 1.5 million in 1999. These technological advances are enabling
communications providers to harness multiple applications, such as voice, data
and video, on a single network, creating new types and combinations of services
available to a broader range of users.

Industry Challenges

     The multiple forces affecting the telecommunications industry, including
global deregulation, have led to increased competition and complexity in the
market for all types of communications services. To gain or maintain a
competitive advantage, communications service providers and the technology and
financial firms that focus on the telecommunications industry must understand
the growing complexities and how to best take advantage of the market's
opportunities and challenges, including those driven by the rapid growth of
e-business. With this understanding, these companies must develop sound
strategic plans and implement effective solutions that best exploit the market's
dynamics. To compete effectively, companies must fully understand the
enterprise-wide implications of a proposed solution and must implement these
solutions swiftly with the most effective technologies, systems and processes.

     Because the expertise needed by communications companies to address the
market's needs is typically outside their core competencies, they must either
recruit and employ experts or retain outside specialists. Due to the range of
expertise required and the time associated with hiring and training new
personnel, bringing expertise in-house is often not a viable option. When
retaining outside specialists, communications companies need experts that fully
understand the telecommunications industry and can provide timely and unbiased
advice and recommendations.

OUR SOLUTION

     We provide a comprehensive range of services, including strategy,
management, operational and e-business support to communications service
providers, technology companies and financial services firms in the United
States, Canada, Europe and other major international markets. Our solutions
encompass the following key elements.

     - Exclusive focus on the telecommunications and e-business
       industries. Since our founding in 1990, we have occupied a unique
       position in the consulting arena, with our exclusive focus on the
       telecommunications industry and our more recent focus on the e-business
       marketplace. Our consultants have significant industry and consulting
       experience across critical business disciplines. Our customers rely on
       our expertise and reputation, not only to help them keep up with market
       growth but to help them deal with the trends as they arise and adapt
       their business plans to meet the demands of the future. Our
       telecommunications and e-business focus allows us to best fulfill our
       clients' needs and continuously refine our services by staying at the
       forefront of, and helping to define, industry standards.

     - Integrated, complete solution. We use our industry expertise to provide
       comprehensive solutions from initial, high-level strategic assessments of
       clients' needs through improvements to operations. We have consulting
       experience with all major aspects of managing a telecommunications
       company, from product launch through order entry, service provisioning
       and billing. Our complete solution addresses the business, information
       technology and operational needs associated with all aspects of our
       clients' requirements. We work with telecommunications providers by
       delivering business planning, management support, process development,
       operations support, systems requirements, selection and implementation.
       We also use our understanding of service providers' needs to help the
       software and technology companies that serve the telecommunications
       industry to define strategies, develop applications, respond to requests
       for proposals and implement their solutions within the service provider
       environment. Finally, we facilitate the evaluation of proposed
       investments in telecommunications companies and related technology
       companies by investment banking and private equity firms by providing
       prospect evaluation, due diligence and post investment support services.

     - Partnership with clients. We develop long-term relationships with our
       clients as we demonstrate our understanding of all aspects of their
       business. We work closely with senior management to understand, predict
       and address our clients' evolving strategic and operational business
       needs. A majority of our current top 20 customers who have been in
       business since 1995 have been customers of ours since then. We expect to
       develop long-term relationships with our more recent clients by gaining a
       deep understanding of their business and providing a broad array of
       services.

     - Global presence. Our knowledge and focus on the trends impacting markets
       abroad enable us to provide the expert advice needed by international
       clients competing in newly deregulated markets and by U.S. companies
       seeking to expand their global reach. We have worked with clients across
       the globe, focusing primarily on North America and Europe. At the end of
       1998, consulting engagements in Europe represented 5.1% of our total
       revenues; for the nine month period for 1999, revenues from European
       engagements represented over 21.6% of our total revenues. We continue to
       expand our geographic presence in key locations based on our clients'
       needs and opportunities.

     - Industry leading consultants. We use seasoned telecommunications
       professionals with telecommunications industry expertise. Our senior
       officers and principals average more than 15 years of financial,
       operational or systems experience in competitive telecommunications
       markets. Our consultants average over ten years of telecommunications
       industry experience. This extensive experience has positioned our team to
       set standards as industry leaders and

                                       39
<PAGE>   41

       means that all of our project team members bring hands-on expertise and
       practical insight to each engagement.

     - Proprietary methodologies. Our proprietary methodologies are consulting
       guidelines and processes that we have created and which are updated by
       our consultants based on their experience over many consulting
       engagements. Our consultants use these methodologies to win engagements
       and help clients improve productivity, gain a competitive advantage,
       reduce time to market and market entry risk, and increase revenues and
       profits. The following are our toolsets.

          TMNG Lexicon is a comprehensive collection of business and systems
          requirements for the competitive telecommunications industry and
          covers all key functional operations areas, such as order entry,
          billing and customer care.

          QBC (Quality Billing Center) is a process model that measures the
          entire revenue flow and is designed to help carriers improve cash
          flow, reduce call center volumes and diminish customer billing
          complaints and challenges.

          TMNG CLEC Planner is an economic planning tool designed for
          competitive local telephone carriers.

          Margin Master is an activity based costing model designed specifically
          for competitive carrier cost assignment and management.

          C-B-I (Carried to Billed to Invoiced) is designed to allow service
          providers to track calls and other billable events from carried to
          billed to invoiced.

          TMNG e-Lexicon is being developed as a comprehensive collection of
          business and systems requirements for telecommunications companies
          serving e-business customers and developing their own web-based
          capabilities.

     - Vendor and technology neutral. Because we focus on management consulting,
       we are in a unique technology- and vendor-neutral position to make
       unbiased evaluations and recommendations that are based on a thorough
       knowledge of each solution and each client's situation. Therefore, we are
       able to capitalize on our extensive experience across complex
       multi-technological telecommunications and back office systems
       environments to provide the most sound and practical recommendations to
       our clients. Because of our neutrality, we believe we are trusted for our
       unbiased opinions in the telecommunications community, which has allowed
       us to play a key role in setting industry standards. For example, the
       European Billing Association, a non-profit trade association, endorsed
       our Quality Billing Center as the chosen billing and service management
       standard for the European carrier community.

OUR STRATEGY

     Our objective is to establish ourself as the telecommunications consulting
company of choice to communications service providers, technology companies and
financial services and investment banking firms. The following are the key
strategies we intend to pursue to meet this objective.

     - Expand geographic reach to serve our clients' global needs. We plan to
       continue to expand geographically to deliver our services and solution
       capabilities to client companies located around the world. By offering
       our full range of professional services on a global basis, we believe we
       can broaden market awareness about our services and solutions to create
       new revenue opportunities. In Europe, the competitive market expertise of
       our U.S. consultants is a key factor for European companies facing the
       business issues associated with deregulation and increased competition.
       Our expertise in Europe can also play a key role for U.S. companies
       expanding their European business.

     - Focus on supporting our current target market's e-business needs through
       our TMNG.com business. Because communications service providers represent
       the infrastructure of the internet, the ability of these service
       providers to build an infrastructure to meet the demand for increased
       internet traffic will be critical to their businesses. More specifically,
       the growth of the internet has also led to a greater demand for
       internet-based business support services and the seamless integration of
       electronic services with traditional means of interacting with customers.
       Through TMNG.com, we are combining our telecommunications knowledge with
       our developing e-business expertise to help telecommunications service
       providers build the infrastructure, systems, processes and services to
       address these opportunities arising from the growth of the internet. As
       communications service providers begin to deploy their application
       hosting strategies, TMNG.com will also address their back-office
       requirements to support their application-based initiatives.

     - Expand long-term client relationships. We build long-term relationships
       with our customers by delivering high quality solutions to help our
       clients set their strategies and operate as efficiently as possible in
       the rapidly changing telecommunications environment. We believe this
       focus improves client satisfaction and results in two major benefits for
       us: follow-on engagements with existing, satisfied clients and referrals
       for new clients. Expanding our existing client relationships will allow
       us to jointly plan future projects and, in particular, develop large,
       multi-year engagements. The dynamic nature of the telecommunications
       industry generates a continuing need for our services, and clients come
       back to us because of our knowledge of their systems and architectures
       and their satisfaction with our services.

     - Further develop and enhance our expandable business model for continued
       growth. We plan to further enhance our expandable business model to
       accommodate anticipated need for our services generated by industry
       growth. The following are the key elements of our business model.

          Attracting and retaining high quality, experienced consultants. We
          seek to attract high quality consultants with a broad range of
          experience and knowledge within the telecommunications industry
          through aggressive recruitment efforts, including focused external
          recruiting, in-house recruiting specialists and consultant referral
          incentive programs. We retain our consultants through a variety of
          programs, including our stock option plan, competitive compensation
          packages, flexible employment model and dynamic, challenging
          assignments at the forefront of the telecommunications industry.

          Creating business processes that can be duplicated worldwide. To
          support our anticipated growth, we are creating business processes
          that we can use worldwide in any consulting engagement. Our toolsets
          provide our consultants with methodologies that they use to augment
          their experience and help analyze and solve clients' problems. We are
          also building a network of eRooms to serve as a knowledge base, enable
          consultant collaboration on engagements and provide support
          information and updates of our current toolsets and releases of next
          generation tools.

          Maintaining a flexible organization with minimal physical
          structure. We intend to use our internet communication capabilities to
          retain our flexible, "virtual" structure as we grow. We are developing
          a contingent employee model to enable us to hire and retain
          consultants by providing them with increased benefits. We believe the
          model allows us to better manage utilization and to minimize unbilled
          consultant time. We also do not expect to invest heavily in facilities
          and plan to rely on electronic telecommunications to support our
          organization.

     - Extending our market leadership position and building our brand. We
       intend to expand our leadership position in the telecommunications
       consulting industry and to establish ourselves as the consulting firm of
       choice for communications service providers and the technology and
       banking companies that serve them. We intend to capitalize on our
       extensive industry

                                       41
<PAGE>   43

       knowledge, strong client base, and highly qualified and experienced
       professionals to help our clients provide more value-added services to
       their customer base. We also have several marketing initiatives underway
       to continue building our corporate brand.

PROPRIETARY METHODOLOGIES

     We have created methodologies which are unique to our company and based on
our consultants' experience. We continually invest in these toolsets by updating
them to keep them at the forefront of the industry. The following are our
methodologies.

     - TMNG Lexicon: a comprehensive collection of business requirements for the
       competitive telecommunications industry that harnesses the collective
       experience, knowledge and lessons learned from top professionals in the
       industry. From order entry to billing to customer care, it covers every
       functional area typically found in a telecommunications company, and now
       contains over 4,000 requirements. On an ongoing basis, the Lexicon is
       modified, tested and updated to reflect additional knowledge gained and
       changes in the market.

     - QBC (Quality Billing Center): a process model that measures the flow of
       revenue from beginning to end that is tailored to a carrier's business
       systems and process environment. Successfully implemented at
       telecommunications companies around the world, the QBC provides key
       benefits and measurable results, including improved cash flow, reduced
       call center volumes, and diminished customer billing challenges. The
       European Billing Association recently endorsed our QBC as the best of
       breed in telecommunications process measurement tools.

     - TMNG CLEC Planner: an economic planning tool developed exclusively for
       competitive local telephone carriers. It is used to:

        - make resale versus facility-based decisions;

        - determine transition plans;

        - make market entry decisions;

        - identify profitable target markets;

        - develop resource plans that align with revenue forecasts; and

        - analyze pricing strategy impacts.

     - Margin Master: an activity-based costing tool developed for the
       telecommunications industry that helps carriers determine product profit
       margins. It supports decisions in a bundled product offering and enables
       market segment, region, channel, and product-specific analysis. With
       growing pressure on margins and reliance on bundled service offerings,
       our Margin Master tool becomes increasingly valuable.

     - C-B-I (Carried to Billed to Invoiced): a methodology that assists
       carriers with the complex task of reconciling incoming call records,
       customer billing, and invoices from their service provider. This
       proprietary tool allows us to design systems resellers use to track calls
       and other billable events from "carried to billed to invoiced," with the
       objective of maximizing revenue by minimizing or eliminating lost
       billable events.

     - TMNG e-Lexicon: currently under development, it will be the first toolset
       in our next generation process architectures. The e-Lexicon will
       capitalize on our experience and understanding of the requirements being
       driven by the convergence of telephony and the Internet in areas such as
       electronic bill presentment and payment and web-based customer service.
       This toolset will also capitalize on our extensive knowledge of the
       existing telecommunications infrastructure, and combine that knowledge
       with our experience,

                                       42
<PAGE>   44

       understanding, and research of the leading edge business support systems
       and operations support systems software solutions to develop the
       e-Lexicon.

CUSTOMERS AND SERVICES

     We provide services to customers in key market segments of the industry.
Since 1990, we have performed consulting assignments for over 170 companies,
including over 80 telecommunications service providers, over 50 technology
companies, including global consulting firms, and over 20 investment banking and
financial services firms. For the nine months ended October 2, 1999,
telecommunications service providers accounted for 79.0% of our revenues,
technology companies accounted for 20.0% of our revenues and investment banking
and financial services firms accounted for one percent of our revenues. Our
customer concentration and our principal customers have in the past changed, and
may in the future change, based on customer requirements and the timing of
completion of engagements. Accordingly, investors should not assume that
customers in a particular fiscal period will be customers of ours in future
periods. For the nine months ended October 2, 1999, Williams Communications
Group and diAx each accounted for more than 10% of our revenues.

     In October 1999, we reached an agreement in principle with Williams
Communications under which Williams Communications will commit to $22 million of
consulting fees over three years. We expect to enter into a definitive
consulting agreement with Williams Communications reflecting these terms prior
to the end of 1999. In addition, in October 1999, we issued Williams
Communications a warrant to purchase 500,000 shares of our common stock at an
exercise price of $2.00 per share. Williams did not pay any separate cash
consideration for this warrant.

COMMUNICATIONS SERVICE PROVIDERS

     We provide all types of carriers and service providers with services
ranging from high-level strategy definition through improvements to operations
to help extend their worldwide reach.

     Strategic Consulting. We analyze market trends and dynamics for
telecommunications service providers and advise them on market evolution and
development. We also help service providers define, refine and implement
strategies through business case development and market launch planning. In
addition, we analyze acquisition opportunities to determine if they are
complementary to strategies our service provider clients are implementing.

     Process Development and Operations Support. We have spearheaded numerous
engagements to design infrastructure, improve processes, and provide operations
support. When telecommunications providers implement new business support
systems and operations support systems, they are seeking to maximize efficiency
and integration in order processing and customer care as well as timeliness and
accuracy in the revenue stream from call processing to billing and payment
processing. Our experience includes revenue assurance and reporting, performance
and cost benchmarking, change management and revenue operations management. We
help clients improve the efficiency, integration, and timeliness of their order
processing, provisioning, billing and customer care systems. Using our unique
process models, QBC and CBI, we improve the timeliness, accuracy and
completeness of carriers' revenue stream management.

     Systems Requirements, Selection and Implementation. We have extensive
expertise in the area of systems assessment, requirements definition, vendor
selection, implementation management, testing, and project and program
management. We assist service providers in preparing and managing requests for
proposals for software systems purchases. Our unique, vendor-neutral and
technology-neutral position ensures that the solutions we recommend are based on
what is best for our clients' businesses.

                                       43

TECHNOLOGY, SOFTWARE AND CONSULTING COMPANIES

     Our extensive first-hand knowledge of incumbent and emerging service
providers' needs provides a solid knowledge base of services for technology and
software companies and positions us as subject matter experts to other
consulting companies.

     Product development strategic consulting. We help technology and software
companies analyze and focus their product and development strategies and efforts
to meet the needs of telecommunications service providers. Our knowledge of
service provider requirements, along with our toolsets, provides significant
benefit to technology companies as they develop new products and applications.
In particular, our TMNG Lexicon toolset helps facilitate rapid analysis of
technology companies' products and product plans. We anticipate that our TMNG
e-Lexicon toolset will also be used for this purpose.

     Market research and analysis. We help technology and software companies
analyze market trends and dynamics to improve their ability to respond to the
requirements of changing and evolving markets. We also analyze acquisition and
investment opportunities for our clients.

     Responses to requests for proposals. We assist technology, software and
consulting companies in responding to requests for proposals that they receive
from service providers and others. Our expertise enables us to ascertain the
most critical elements of a request for proposal and to help our clients prepare
responses that address the service provider's key requirements.

     Implementation support. For global consulting firms that have engagements
which require specialized telecommunications expertise, we serve as the
telecommunications experts. In addition, we support our software clients by
assisting with program management for software implementation. These assignments
capitalize on our extensive understanding of both the software solution and the
service provider communities.

INVESTMENT BANKING AND FINANCIAL SERVICES FIRMS

     We assist investment banking and financial services firms with prospect
validation and due diligence in connection with planned investments and other
transactions. Our broad knowledge of the industry and subject matter expertise
speed up the evaluation of proposals and potential investment candidates. Our
prospect validation services include candidate validation, business plan
development, financial modeling and contract development and negotiation. Our
consultants and toolsets also facilitate rapid development and execution when
conducting due diligence. Our services in this area include business plan
evaluation and validation, financial model analysis, product and evaluation,
benchmarking, organization and business process validation, systems evaluation,
and network plan reviews.

     A Major Global Systems Integration and Software Services Firm. We have

Financial Services Companies

     A Leading Merchant Banking Firm. We provided the primary due diligence for
a potential investment in a European data services company. In this capacity, we
completed due diligence reviews of the underlying network and technology systems
proposed for the venture. We also developed the business plan assumptions and
financial analysis, including the cost structure and revenue plans, transfer
costing methodology, and the voice implementation strategy.

MARKETING, SALES AND STRATEGIC ALLIANCES

     Our marketing and sales efforts are focused on growing our client
relationships, developing new relationships, and building our brand recognition
in the U.S. and abroad. We market and sell our services through multiple
channels, including our partners, principals, and consultants; long-term client
relationships; relationships with strategic partners; advertising; tradeshows;
web site marketing; and public relations.

Marketing

     Our marketing activities are focused on expanding our presence and brand
recognition in the U.S. and abroad, to further our position as the consulting
firm of choice for telecommunications service providers and the technology and
banking firms that serve them.

     Our integrated marketing programs include:

     - TMNG, TMNG.com and TMNG Europe advertising campaigns;

     - ongoing Web site management and enhancement;

     - marketing communications;

     - industry trade shows and speaking engagements;

     - knowledge and toolset packaging;

     - ongoing public relations campaign; and

     - articles authored by us or our consultants published in trade journals.

     Significant marketing efforts are focused on TMNG.com, including a newly
developed TMNG.com advertising campaign. In concert with this advertising
campaign, we reinforce the TMNG.com message and brand with marketing
communications, trade shows, publicity and web site activities. Additionally, a
new TMNG Europe campaign is under development.

                                       46
<PAGE>   48

     We are an active participant in telecommunications and internet telephony
conferences and trade shows in North America and Europe. We regularly
participate as keynote speakers, panel moderators, workshop leaders, and
exhibitors. Considered an industry authority, we are frequently consulted by the
trade media. In 1998 and 1997, Mr. Nespola, our President and Chief Executive
Officer, was named to Phone+ magazine's annual list of the most influential
people in competitive long distance telecommunications. In each year, he was the
highest ranking non-carrier executive selected for the list.

Sales

     We sell our services directly to senior and management-level executives of
communications service providers in the United States, Europe, Canada, Asia,
Australia and South America, primarily through relationship sales. Our officers
and principals sell the majority of our engagements. In addition, our
consultants also sell, and are encouraged to do so with a compensation structure
that provides both financial and equity incentives. In pursuing new business,
our sales team and consultants emphasize our industry reputation, experience,
vendor- and technology-neutral position and time-saving proprietary business
tools.

     Our sales strategy centers on building long-term relationships with our
clients, to gain new and follow-on engagements within existing accounts and
referrals for new clients. Expanding our existing client relationships will
allow us to jointly plan future projects and, in particular, develop large,
multi-year engagements.

Strategic Alliances

     We have entered into, and intend to continue entering into, strategic
alliances with a select group of technology and related companies. The primary
goals of our strategic alliances are:

     - to enhance our overall service offerings;

     - to create or identify new revenue opportunities through referrals and the
       creation of new service offerings; and

     - to increase our credibility and visibility in the marketplace through
       collaboration in joint marketing.

     We currently have strategic alliances with Emerald Solutions, IBM,
PricewaterhouseCoopers and Tanning Technology Corporation. We do not enter into
exclusive arrangements with technology companies so that we can maintain our
vendor neutrality.

OPERATIONS

     We believe that a key factor differentiating us from other consulting firms
is our operational and organizational structure. We have developed an
operational model that enables us to limit our physical facilities and other
overhead requirements and maximize utilization of the consultant base. This
structure enables us to control costs and contributes to our operating margins.

     We limit our facilities requirements through the use of use electronic
communication. Although our consultants are geographically dispersed throughout
the United States and in international locations, our only corporate office
facility is our headquarters in the Kansas City area. Our consultants typically
do not require office facilities as they work either from the customer's site or
their homes.

     To provide our consultants with additional infrastructure support, we are
creating a series of eRooms which consultants will be able to access through the
internet. We have established an eRoom that includes proposals we have made for
consulting engagements and an eRoom containing repositories of deliverables
generated during consulting engagements. We are also building engagement
specific eRooms to facilitate collaboration among consultants that are in
disparate locations but are working on the same engagement. We have developed a
human resources eRoom

                                       47
<PAGE>   49

that provides information regarding compensation and benefits and fulfills the
same function as a bricks and mortar human resources office. We plan to develop
eRooms that provide consultant support for our proprietary methodologies. Our
eRooms are designed to provide our consultants with access to the same types of
information and support they would otherwise need to receive from a corporate
headquarters organization.

     To track consultant utilization and project profitability, we have
established a sophisticated management reporting system. This system enables us
to track consultant utilization and productivity as well as costs related to and
profitability of particular projects and engagements.

     Our staffing needs are coordinated by our project staffing group, which
uses a database containing information on the availability and subject matter
expertise of our consultants. Through the use of this database, we are able to
effectively match consultant availability and expertise with the needs of
incoming engagements.

     Our organization is relatively flat in nature. As a result, we do not have
layers of management and require only a relatively small headquarters staff for
administrative purposes. In addition, our consultants play a key role in selling
new consulting services as well as working on their current engagements.

HUMAN RESOURCES

     We believe that our ability to recruit and retain experienced,
highly-qualified and highly-motivated personnel has contributed greatly to our
success to date and will be critical for us in the future. We seek to offer a
positive environment and corporate culture and to offer significant financial
opportunities.

     We offer a flexible recruiting model that we believe enhances our ability
to attract consultants and to effectively manage utilization. Our consultants
may work for us as employees, independent contractors or as contingent
employees. Contingent employees will, unlike independent contractors, receive
company-paid medical insurance, vacation and other employee benefits. Instead of
receiving a regular salary, however, contingent employees will only be paid for
time spent working on consulting projects for customers or working on internal
projects. We intend to begin offering contingent employment to a selected
portion of our independent contractor base later this year. Generally, we will
offer contingent employment to independent contractors that are regularly
involved in consulting projects, have a broad range of expertise and are highly
utilized by us. Our current independent contractor base also includes
individuals with specialized expertise in discrete areas, and we typically
deploy these individuals only when their unique expertise is necessary. We
expect that we will continue to retain these individuals as independent
contractors.

     As of October 2, 1999, we had approximately 210 consultants available to
work on engagements for us. Of these, 51 were full-time employees and
approximately 115 were working on engagements for us as independent contractors.
The remaining consultants are available to work on engagements as we need them.
In addition to our consultants, we have a headquarters staff of 15, which
includes our Chief Executive Officer, Chief Financial Officer and other
administrative personnel.

     We retain our professionals through the use of many initiatives. We
compensate our employees through a combination of regular cash compensation,
performance-based cash incentive compensation and participation in our stock
option and other equity incentive plans and independent contractors through a
competitive daily service rate. Through the use of the three-pronged employment
model option, we offer significant flexibility to suit the varied needs and
skill sets of our consulting base. Further, because we do not require
consultants to work from a central office, consultants are not required to move
to a particular location to join us, which offers geographic flexibility to our
consulting base.

                                       48

COMPETITION

     The market for telecommunications consulting services is relatively new,
highly fragmented and changing rapidly. We face competition from major business
consulting firms, the consulting arms of accounting and other professional
services organizations and our customers' internal resources. We consider some
of our principal competitors to be:

     - American Management Systems;

     - Andersen Consulting;

     - Booz-Allen & Hamilton;

     - The Boston Consulting Group;

     - Cap Gemini;

     - KPMG Peat Marwick; and

     - PricewaterhouseCoopers.

     These competitors are major consulting firms that provide a broad range of
services to companies in many industries, including the telecommunications
industry. Many of these competitors have significantly greater financial,
technical and marketing resources and greater name recognition than we do.

     We believe, based on our revenue levels and our market research, that we
are among the largest stand-alone providers of telecommunications management
consulting services.

     We have faced, and expect to continue to face, additional competition from
new entrants into our markets. We have also experienced increased price
competition, particularly from larger firms that have the financial resources to
aggressively price engagements that they have a particular interest in
obtaining. Increased competition could result in:

     - price reductions;

     - fewer client projects;

     - underutilization of consultants;

     - reduced operating margins; and

     - loss of market share.

     The principal competitive factors in our market include responsiveness to
the needs of customers, quality and reliability of consultants, price, project
management capability and technical expertise. We believe that our ability to
compete depends in part on performance, a focused service offering formula, the
price/value formula of our service offerings, responsiveness to customer needs
and our ability to hire, retain, and motivate key personnel.

INTELLECTUAL PROPERTY

     Our success is dependent, in part, upon our proprietary processes and
methodologies, and we rely upon a combination of copyright, trade secret, and
trademark law to protect our intellectual property. We have obtained federal
registration for two trademarks in the United States and have filed applications
to register eight other marks in the United States. It is possible that third
parties may challenge our trademark applications.

     We do not have any patent protection for the proprietary methodologies used
by our consultants. We currently do not anticipate applying for patent
protection for these toolsets and methodologies.

     We enter into confidentiality agreements with our employees, independent
contractors and clients. We also limit access to and distribution of our
proprietary information. In addition, we have entered into non-competition
agreements with certain of our key employees. We cannot assure you that the
steps we have taken in this regard will be adequate to prevent or deter
misappropriation of our proprietary information or that we will be able to
detect unauthorized use and take appropriate steps to enforce our intellectual
property rights. Misappropriation or unauthorized use of our intellectual
property could harm our business.

FACILITIES

     Our principal executive offices are located in a 3,357 square foot facility
in Overland Park, Kansas. This facility houses our executive, corporate and
administrative offices. We occupy these premises under a lease which expires in
July 2003. We anticipate that our current executive office facility will be
sufficient to meet our corporate facilities needs for the foreseeable future.

LEGAL PROCEEDINGS

     In June 1998, the bankruptcy trustee of one of our former clients,
Communications Network Corporation, sued us in the U.S. Bankruptcy Court in New
York seeking recovery of $160,000 in improper payment of consulting fees paid by
the former client during the period from July 1, 1996, when an involuntary
bankruptcy proceeding was initiated against the former client, through August 6,
1996, when the former client agreed to an order for relief in the bankruptcy
proceeding, and $160,000 in consulting fees paid by the former client after
August 6, 1996. The bankruptcy trustee has also sued us for at least $1.85
million for breach of contract, breach of fiduciary duties and negligence.
Although we cannot give you any assurance as to the ultimate outcome of this
proceeding, we believe we have meritorious defenses to the claims made by the
bankruptcy trustee, including particularly the claims for breach of contract,
breach of fiduciary duty and negligence, and that the ultimate resolution of
this matter will not materially harm our business.

BOARD COMPOSITION

     Our bylaws currently authorize seven directors. Our certificate of
incorporation and bylaws provide that our board will be divided into three
classes, Class I, Class II and Class III, with each class serving staggered
three-year terms. The Class I directors, Messrs. Matthes and Woo, will stand for
reelection at the 2000 annual meeting of stockholders. The Class II directors,
Messrs. Rosati, Sisco and Wilkens, will stand for reelection at the 2001 annual
meeting of stockholders. The Class III directors, Messrs. Behrman and Nespola,
will stand for reelection at the 2002 annual meeting of stockholders. Any
additional directorships resulting from an increase in the number of directors
will be distributed among the three classes so that, as nearly as possible, each
class will consist of one-third of the directors. This staggered classification
of the board of directors may have the effect of delaying or preventing changes
in control or management.

COMMITTEES OF THE BOARD OF DIRECTORS

     The board of directors has established a compensation committee and an
audit committee. The compensation committee, consisting of Messrs. Behrman,
Matthes and Wilkens, reviews and approves the salaries, bonuses and other
compensation payable to our executive officers and administers and makes
recommendations concerning our employee benefits plans.

     The audit committee, consisting of Messrs. Rosati and Wilkens, recommends
the selection of independent public accountants to the board of directors,
reviews the scope and results of the audit and other services provided by our
independent accountants and reviews our accounting practices and systems of
internal accounting controls.

DIRECTOR COMPENSATION

     Directors who are also our employees currently receive no additional
compensation for their services as directors of our company. Directors who are
not our employees may occasionally

                                       54

receive options under our 1998 equity incentive plan. Messrs. Rosati and Wilkens
each received an option to purchase 37,500 shares of our common stock when they
joined the board of directors in 1999. We have no other director compensation
arrangements, other than reimbursement for travel expenses and other
out-of-pocket costs incurred in connection with directors' attendance at
meetings.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     No member of our compensation committee serves as a member of the board of
directors or compensation committee of any entity that has one or more executive
officers serving as a member of our board of directors or compensation
committee.

EMPLOYMENT AND NONCOMPETITION AGREEMENTS

     In connection with our merger and recapitalization in 1998, we entered into
a noncompetition agreement with Behrman Capital and an affiliated fund and
Messrs. Nespola, Peck and Woo. We also entered into employment agreements with

to further refrain from any solicitation of our employees or interference with

Woo, on the earlier of February 12, 2005 on the third anniversary of the date of
termination of their employment with us. Alan Staples, a former stockholder and
employee of ours, is also subject to the provisions of this agreement through
November 2001.

     Employment Agreements. We have employment agreements with Messrs. Nespola,
Peck and Woo, which set forth the terms and conditions of their employment with
us. These terms and conditions include:

     - compensation in the form of annual salary, bonus and other compensation

</TABLE>



     Potential realizable value has been calculated based on an assumed initial
public offering price of $15.00 per share. In 1998, we granted options to
purchase an aggregate of 1,099,750 shares of common stock to our employees,
directors and consultants. Generally, we grant options at an exercise price
equal to the fair market value of the underlying common stock on the date of
grant, as determined by our board of directors, and the options vest over three
or four years from the date of grant. In determining the fair market value of
our common stock, our board of directors considers valuations of comparable
companies, valuation reports and analyses prepared by third parties, and the
lack of liquidity of our securities. Once we become a publicly held company, the
fair market value of our stock will equal its trading market price on the day of
the grant.


     In accordance with the rules of the SEC, the above table sets forth the
potential realizable value over the ten-year period from the grant date to the
expiration date, assuming rates of stock appreciation of five percent and ten
percent compounded annually. These amounts do not represent our estimate of
future stock price performance. Actual realizable values, if any, of stock
options will depend on the future performance of our common stock.


     On July 26, 1999, we granted Mr. Klumb an option to purchase 250,000 shares
of our common stock. This option was granted under our 1998 equity incentive
plan with an exercise price of $2.00 per share. The potential realizable values
at assumed annual rates of stock price appreciation for the option term at 5%
and 10% are $6.1 million and $9.7 million, respectively.

AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES

     The following table set forth information for each of the officers named in
the summary compensation table concerning option exercises for fiscal year 1998,
and exercisable and unexercisable options held at January 2, 1999. The officers
named in the summary compensation table did not exercise any options during
fiscal year 1998.


     The "Value of Unexercised In-the-Money Options at January 2, 1999" is based
on a value of $15.00 per share of our common stock, which is the initial public
offering price, less the per share exercise price, multiplied by the number of
shares issued upon exercise of the option. All options were granted under our
1998 equity incentive plan.

STOCK PLANS

1998 Equity Incentive Plan

     The amended and restated 1998 equity incentive plan was adopted and
approved by our board of directors and by our stockholders in September, 1999.
When we amended and restated our 1998 equity incentive plan, we combined both
our 1998 equity incentive plan and our 1998 consultant equity incentive plan.
The 1998 equity incentive plan provides for the grant to employees of incentive
stock options within the meaning of Section 422 of the Internal Revenue Code,
and for the grant to employees, directors and consultants of nonstatutory stock
options and stock purchase rights.

     As of October 2, 1999, a total of 1,950,000 shares of common stock were
reserved for issuance pursuant to the 1998 equity incentive plan, of which
options to acquire 1,695,250 shares were issued and outstanding as of that date.
The 1998 equity incentive plan provides for annual increases in the number of
shares available for issuance thereunder, on the first day of each new fiscal
year, effective beginning with fiscal year 2000, equal to the lesser of (a)
1,500,000 shares, (b) five percent of the outstanding shares of common stock on
the first day of the fiscal year, or (c) such lesser amount as the board may
determine.

     The board of directors or a committee of the board administers the 1998
equity incentive plan. In the case of options intended to qualify as
"performance-based compensation" within the meaning of Section 162(m) of the
Internal Revenue Code, the committee will consist of two or more "outside
directors" within the meaning of Section 162(m) of the Internal Revenue Code.
The administrator has the power to determine the terms of the options or share
purchase rights granted, including the exercise price, the number of shares
subject to each option or share purchase rights, the exercisability of the
options and the form of consideration payable upon exercise.

Options

     We determine the exercise price of nonstatutory stock options granted under
the 1998 equity incentive plan, but with respect to nonstatutory stock options
intended to qualify as "performance-based compensation" within the meaning of
Section 162(m) of the Internal Revenue Code, the exercise price must at least be
equal to the fair market value of the common stock on the date of grant. The
exercise price of all incentive stock options granted under the 1998 equity
incentive plan

                                       57
<PAGE>   59

must be at least equal to the fair market value of the common stock on the date
of grant. With respect to any participant who owns stock possessing more than
ten percent of the voting power of all classes of our outstanding capital stock,
the exercise price of any incentive stock option granted must equal at least
110.0% of the fair market value on the grant date and the term of such incentive
stock option must not exceed five years. The term of all other options granted
under the 1998 equity incentive plan may not exceed ten years.

     An optionee generally must exercise an option granted under the 1998 equity
incentive plan at the time set forth in the optionee's option agreement after
the end of optionee's status as an employee, director or consultant of ours, or
within 12 months after the optionee's termination by death or disability, or
within a longer time period not exceeding five years, but in no event later than
the expiration of the option's ten year term. If an optionee is terminated by us
or any of our subsidiaries for cause, as defined in the 1998 equity incentive
plan, then any option held by the optionee shall be terminated immediately or
after any period of time as determined by the administrator.

     The administrator determines the exercise price of stock purchase rights
granted under the 1998 equity incentive plan. In the case of stock purchase
rights, unless the administrator determines otherwise, the restricted stock
purchase agreement entered into in connection with the exercise of the stock
purchase rights shall grant us a repurchase option that we may exercise upon the
voluntary or involuntary termination of the purchaser's service with us for any
reason, including death or disability. The purchase price for shares we
repurchase pursuant to restricted stock purchase agreements shall be the
original price paid by the purchaser and may be paid by cancellation of any
indebtedness of the purchaser to us. The repurchase option shall lapse at a rate
that the administrator determines.

     An optionee generally may not transfer options and stock purchase rights
granted under the 1998 equity incentive plan and only an optionee may exercise
an option and stock purchase rights during his or her lifetime.

     The 1998 equity incentive plan provides that upon our dissolution,
liquidation or merger with or into another corporation or a sale of
substantially all of our assets, the successor corporation shall assume or
substitute each option or stock purchase right held by an employee. If the
employee is terminated other than for cause within six months after the
dissolution, liquidation, merger or sale of assets, the vesting of each
outstanding option or stock purchase right will automatically accelerate as to
50% of the unvested shares subject to the option or stock purchase right. All
options or stock purchase rights held by independent contractors and all holders
of options not assumed or substituted by the surviving entity shall be
exercisable for a period of 15 days after the holder receives notice of his or
her rights. The option or stock purchase right will terminate upon the
expiration of the 15 day period.

     Unless terminated sooner, the 1998 equity incentive plan will terminate
automatically in 2008. In addition, we have the authority to amend, suspend or
terminate the 1998 equity incentive plan, provided that no such action may
affect any share of common stock previously issued and sold or any option
previously granted under the 1998 equity incentive plan without the optionee's
written consent.

1999 EMPLOYEE STOCK PURCHASE PLAN

     The board of directors adopted our 1999 employee stock purchase plan in
September 1999 and stockholders approved the 1999 purchase plan in September
1999.

     A total of 200,000 shares of common stock has been reserved for issuance
under the purchase plan. In addition, the 1999 purchase plan provides for annual
increases in the number of shares available for issuance under the 1999 purchase
plan on the first day of each fiscal year, beginning with fiscal year 2000,
equal to the lesser of (a) 200,000 shares of common stock, (b) 0.05% of the

                                       58
<PAGE>   60

outstanding shares of common stock on the first day of the fiscal year or (c)
such lesser amount as may be determined by the board.

     The board of directors or a committee appointed by the board administers
the 1999 purchase plan. The board of directors or its committee has full and
exclusive authority to interpret the terms of the 1999 purchase plan and
determine eligibility.

     Employees are eligible to participate if they are customarily employed by
us or any participating subsidiary for at least 20 hours per week and more than
five months in any calendar year. An employee, however, may not be granted an
option to purchase stock under the 1999 purchase plan if such an employee:

     - immediately after grant owns stock possessing five percent or more of the
       total combined voting power or value of all classes of the capital stock
       of ours; or

     - whose rights to purchase stock under all employee stock purchase plans of
       ours accrues at a rate which exceeds $25,000 worth of stock for each
       calendar year.

     The 1999 purchase plan, which is intended to qualify under Section 423 of
the Internal Revenue Code, contains consecutive, overlapping 24 month offering
periods. Each offering period includes four six month purchase periods. The
offering periods generally start on the first trading day on or after January 1
and June 30 of each year, except for the first such offering period which will
commence on the first trading day on or after the effective date of this
offering and will end on the last trading day on or before June 30, 2001.

     The 1999 purchase plan permits participants to purchase common stock
through payroll deductions of up to 15% of the participant's "compensation."
Compensation is defined as the participant's base straight time gross earnings
and commissions but excludes payments for:

     - overtime;

     - shift premium payments;

     - incentive compensation;

     - incentive payments;

     - bonuses; and

     - other compensation.

     Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each offering period. The price of stock
purchased under the 1999 purchase plan is 85.0% of the lower of the fair market
value of the common stock at the beginning or end of the offering period. If the
fair market value at the end of a purchase period is less than the fair market
value at the beginning of the offering period, participants will withdraw from
the current offering period following the exercise and will automatically
re-enroll in a new offering period. Participants may end their participation at
any time during an offering period, and they will be paid their payroll
deductions to date. Participation ends automatically upon termination of
employment with us.

     A participant may not transfer rights granted under the 1999 purchase plan
other than by will, the laws of descent and distribution or as otherwise
provided under the 1999 purchase plan.

     The 1999 purchase plan provides that, if we merge with or into another
corporation or a sale of substantially all of our assets, a successor
corporation may assume or substitute for each outstanding option. If the
successor corporation refuses to assume or substitute for the outstanding
options, the offering period then in progress will be shortened, and a new
exercise date will be set.

     The 1999 purchase plan will terminate in 2009. However, the board of
directors has the authority to amend or terminate the 1999 purchase plan, except
that, subject to certain exceptions

                                       59
<PAGE>   61

described in the 1999 purchase plan, no such action may adversely affect any
outstanding rights to purchase stock under the 1999 purchase plan.

LIMITATIONS OF LIABILITY AND INDEMNIFICATION MATTERS

     Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except liability for any of the
following:

     - any breach of their duty of loyalty to the corporation or its
       stockholders;

     - acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions; or

     - any transaction from which the director derived an improper personal
       benefit.

     This limitation of liability does not apply to liabilities arising under
the federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

     Our bylaws provide that we shall indemnify our directors and executive
officers and may indemnify our other officers and employees and other agents to
the fullest extent permitted by law. We believe that indemnification under our
bylaws covers at least negligence and gross negligence on the part of
indemnified parties. Our bylaws also permit us to secure insurance on behalf of
any officer, director, employee or other agent for any liability arising out of
his or her actions in such capacity, regardless of whether the bylaws would
permit indemnification.

     We have entered into agreements to indemnify our directors and executive
officers, in addition to indemnification provided for in our bylaws. These
agreements, among other things, indemnify our directors and executive officers
for certain expenses, including any action by us arising out of such person's
services as our director or executive officer, any of our subsidiaries or any
other company or enterprise to which the person provides services at our
request. Such expenses include amounts incurred by any person in an action or a
proceeding such as attorneys' fees, judgments, fines, and settlement amounts.

     We believe that these provisions and agreements are necessary to attract
and retain qualified persons as directors and executive officers.

                              CERTAIN TRANSACTIONS

RECAPITALIZATION TRANSACTION


     On February 12, 1998, we entered into a series of transactions that
resulted in our leveraged recapitalization. Prior to completion of the
recapitalization, we made distributions totaling $4.7 million to our
stockholders and all stockholders' notes receivable were paid off. The
recapitalization included the following transactions (share information set
forth below with respect to the recapitalization gives effect to the 1-for-2
reverse stock split that we effected in November 1999):


     - we converted all authorized non-voting common stock to voting common
       stock and we declared a 3,272.73-for-one stock split resulting in total
       number of authorized shares of 60,000,000 at the time of the
       recapitalization, which is 30,000,000 after the reverse stock split, with
       22,500,000 shares issued and outstanding;

     - Behrman Capital and an affiliated fund, Strategic Entrepreneur Fund II,
       L.P., organized Behrman Capital TMNG, Inc., a new company, and
       contributed $20.0 million in exchange for 100% of the new company's
       capital stock. The new company was formed as a transitory corporation
       solely for the purpose of effecting the recapitalization and has not
       carried on any activities to date other than those related to its
       formation and the recapitalization;

     - Behrman Capital exchanged 100% of its stock in the new company for
       13,500,000 newly issued shares of TMNG common stock. The new company was
       then merged into TMNG with TMNG being the surviving corporation. At this
       time we changed our income tax status to a "C" corporation from an "S"
       corporation;

     - we entered into a senior bank credit facility that provided $24.0 million
       in term loans and a $5.0 million revolving credit facility from Chase
       Manhattan Bank and a syndicate of banks established by Chase Manhattan
       Bank. We utilized the funds provided by the revolving credit facility and
       the proceeds from the merger with the new company to acquire 13,500,000
       shares of common stock from existing shareholders (as of December 31,
       1997) for aggregate consideration of $38.7 million. These shares were
       then retired and returned to the status of authorized but unissued
       shares; and

     - in connection with the recapitalization, we entered into employment
       agreements and a noncompetition agreement with Messrs. Nespola, Peck,
       Staples and Woo.

OTHER TRANSACTIONS

     Mr. Rosati, one of our directors, is also a member of Wilson Sonsini
Goodrich & Rosati, Professional Corporation, which became our outside corporate
counsel in July 1999.

     We have entered into indemnification agreements with each of our directors
and executive officers.

     In November 1998, Mr. Staples entered into a separation agreement and
release and a stock purchase agreement with us, Behrman Capital and its
affiliated entities that are stockholders of ours and Messrs. Nespola, Peck and
Woo. Mr. Staples' company, Revenue Systems Management Company, was also a party
to these agreements. Under the separation agreement, Mr. Staples resigned from
his position with us and his employment agreement with us was terminated. He
received his salary and expenses up to the date of termination and his company
received a lump-sum payment of $95,000. Under the stock purchase agreement, our
existing stockholders repurchased all of Mr. Staples shares of our common stock
for an aggregate repurchase price of $2.7 million.

     Intertech Management Group, Inc. is a customer of ours. Messrs. Matthes and
Sisco, two of our directors, are also directors of Intertech Management Group,
Inc. In addition, Behrman Capital II,

                                       61
<PAGE>   63

L.P. and Strategic Entrepreneur Fund II L.P., venture funds affiliated with
Behrman Capital with whom Messrs. Matthes and Sisco are employed, hold shares of
preferred stock of Intertech that are convertible into approximately 25.0% of
Intertech's outstanding common stock. We provided $329,000 and $2.2 million of
consulting services to Intertech in 1998 and for the nine month period ended
October 2, 1999, respectively.

     Mr. Wilkens, a member of our board of directors, became a director and
non-executive Chairman of the Board of Williams Communications Group, Inc. upon
completion of Williams' Communications Group's initial public offering. Williams
Communications Group was our largest customer during fiscal year 1998 and the
nine months ended October 2 1999. We provided $5.4 million and $15.2 million of
consulting services to Williams in 1998 and for the nine months ended October 2,
1999, respectively.

     In October 1999, we reached an agreement in principle with Williams
Communications under which Williams Communications will commit to minimum levels
of consulting fees of $22 million over three years. In addition, in October
1999, we issued Williams Communications a warrant to purchase 500,000 shares of
our common stock at an exercise price of $2.00 per share.

     During 1996, 1997 and fiscal year 1998, we made payments of approximately
$213,000, $200,000 and $77,000, respectively, to a company owned by Mr. Nespola.
In addition, we made a payment of $100,000 in 1997 to Mr. Nespola. These
payments were for services rendered under consulting agreements between TMNG and
the company owned by Mr. Nespola.

     Through January 2, 1999, we subcontracted with five companies owned by
Messrs. Nespola, Peck and Woo. These companies provided consultants (acting as
independent contractors) to render consulting services to our customers.
Beginning January 3, 1999, we contracted directly with these consultants. Total
services received from these companies was approximately $7.8 million, $9.6
million and $14.9 million in 1996, 1997 and fiscal 1998, respectively. At
December 31, 1997 and January 2, 1999, we had accounts receivable balances due
for these services of $565,000 and $332,000, respectively.

POLICY REGARDING TRANSACTIONS WITH AFFILIATES

     All future transactions with affiliates, including any loans we make to our
officers, directors, principal stockholders or other affiliates, will be
approved by a majority of our board of directors, including a majority of the
independent and disinterested members or, if required by law, a majority of
disinterested stockholders, and will be on terms no less favorable to us than we
could have obtained from unaffiliated third parties.

                             PRINCIPAL STOCKHOLDERS

     The following table sets forth information regarding the beneficial
ownership of our common stock as of October 2, 1999 and as adjusted to reflect
the sale of the shares of common stock in this offering by:

     - each person or entity known by us to own more than five percent of our
       outstanding stock;

     - our Chief Executive Officer, each of the executive officers named in the
       summary compensation table and each of our directors; and

     - all of our directors and executive officers as a group.

     Unless otherwise indicated, the address for each beneficial owner is c/o
The Management Network Group, Inc., 7300 College Boulevard, Suite 302, Overland
Park, Kansas 66210.

     The beneficial ownership is calculated based on 22,571,201 shares of our
common stock outstanding as of October 2, 1999, and 27,261,201 shares
outstanding immediately following the completion of this offering. Beneficial
ownership is determined in accordance with the rules of the SEC and generally
includes voting and investment power with respect to the securities. Unless
otherwise indicated, and subject to applicable community property laws, to the
best of our knowledge, the persons named in this table have sole voting and
investing power with respect to all of the shares of common stock held by them.
Shares issuable upon the exercise of options that are exercisable or become
exercisable within 60 days of October 2, 1999 are considered outstanding for the
purpose of computing percentage ownership of that person, but are not treated as
outstanding for the purpose of computing any other person's ownership
percentage.

     Messrs. Nespola and Peck and Behrman Capital II L.P. and Strategic
Entrepreneur Fund II L.P. have granted the underwriters an option to purchase up
to an aggregate of 692,250 shares of common stock to cover over-allotments, if
any.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL


     We are authorized to issue up to 100,000,000 shares of common stock, $0.001
par value and 10,000,000 shares of undesignated preferred stock. From time to
time, our board of directors may establish the rights and preferences of the
preferred stock. As of October 2, 1999, 22,571,201 shares of common stock were
issued and outstanding and held by 11 stockholders, and zero shares of preferred
stock were issued and outstanding. The following description of our capital
stock is, by necessity, not complete. We encourage you to refer to our
certificate of incorporation and bylaws, which are included as exhibits to the
registration statement of which this prospectus forms a part, and applicable
provisions of Delaware law for a more complete description.


COMMON STOCK

     Each holder of common stock is entitled to one vote for each share held on
all matters to be voted upon by the stockholders and there are no cumulative
voting rights. Subject to preferences that may be applicable to any outstanding
preferred stock, holders of common stock are entitled to receive ratably such
dividends, if any, as may be declared time to time by the board of directors out
of funds legally available for that purpose. See "Dividend Policy." If we
undergo a liquidation, dissolution or winding up, the holders of common stock
are entitled to share in our assets remaining after the payment of liabilities
and the satisfaction of any liquidation preference granted to the holders of any
outstanding shares of preferred stock. Holders of common stock have no
preemptive or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are, in the opinion of our legal counsel,
Wilson Sonsini Goodrich & Rosati, fully paid and nonassessable. The rights,
preferences and privileges of the holders of common stock are subject to, and
may be adversely affected by the rights of the holders of shares of any series
of preferred stock which we may designate in the future.

PREFERRED STOCK

     The board of directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, which may be
greater than the rights of the common stock. It is not possible to state the
actual effect of the issuance of any shares of preferred stock upon the rights
of holders of the common stock until the board of directors determines the
specific rights of the holders of this preferred stock. However, the effects
might include, among other things:

     - restricting dividends on the common stock;

     - diluting the voting power of the common stock;

     - impairing the liquidation rights of the common stock; or

     - delaying or preventing a change in control of us without further action
       by the stockholders.

     Upon the closing of this offering, no shares of preferred stock will be
outstanding.

WARRANTS

     In October 1999, we issued a warrant to purchase 500,000 shares of common
stock to Williams Communications Group at an exercise price of $2.00 per share.
The warrant has a net exercise provision under which the holder may, in lieu of
payment of the exercise price in cash, surrender the warrant and receive a net
amount of shares based on the fair market value of our common stock at the time
of exercise of the warrant, after deducting the aggregate exercise price. No
separate cash consideration was paid for this warrant. The warrant is
exercisable beginning in November 1999 and will expire in October 2004.

REGISTRATION RIGHTS OF CERTAIN HOLDERS

     After this offering, holders of 22,499,998 shares of common stock and a
warrant to purchase 500,000 shares of our common stock or their transferees are
entitled to certain rights with respect to the registration of such shares under
the Securities Act. These rights are provided under the terms of an agreement
between us and the holders of the registrable securities. Beginning 180 days
following the date of this prospectus, holders of at least 15.0% of the
registrable securities may require on up to two occasions, that we use our best
efforts to register the registrable securities for public resale. We are
obligated to register these shares only if the outstanding registrable
securities have an anticipated public offering price of at least $8.0 million.
Also, holders of 25.0% of the registrable securities may require, no more than
once during any six-month period, that we register their shares for public
resale on Form S-3 or similar short-form registration if the value of the
securities to be registered is at least $2.0 million. Furthermore, if we elect
to register any of its shares of common stock for purposes of effecting any
public offering, the holders of registrable securities are entitled to include
their shares of common stock in the registration, but we may reduce the number
of shares proposed to be registered in view of market conditions. These
registration rights have been waived with respect to this offering. We will bear
all expenses in connection with any registration, other than underwriting
discounts and commissions.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF OUR CHARTER AND BYLAWS

     Provisions of Delaware law and our certificate of incorporation and bylaws
could make it more difficult to acquire us by means of a tender offer, proxy
contest or otherwise, or to remove our 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 its potential
ability to negotiate with the proponent of an unfriendly or unsolicited proposal
to acquire or restructure us outweighs the disadvantages of discouraging such
proposals because negotiation of such proposals could result in an improvement
of their terms.

     Our board of directors is divided into three classes. The directors in each
class will serve for a three-year term, with our stockholders electing one class
each year. 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.

     Our certificate of incorporation provides that stockholders may act only at
duly called annual or special meetings of stockholders, not by written consent.
Our bylaws further provide that special meetings of our stockholders may be
called only by the President, Chief Executive Officer or Chairman of the Board
or a majority of the board of directors.

     Our bylaws provide that stockholders seeking to bring business before our
annual meeting of stockholders, or to nominate candidates for election as
directors at our annual meeting of stockholders, must provide timely notice
thereof in writing. The bylaws also specify requirements as to the form and
content of a stockholder's notice. These provisions may preclude stockholders
from bringing matters before our annual meeting of stockholders or from making
nominations for directors at our annual meeting of stockholders.

     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

                                       66
<PAGE>   68

who, together with affiliates and associates, owns or within three years prior
to the determination of interested stockholder status, did own, 15.0% 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.

     Our certificate of incorporation and bylaws do not provide for cumulative
voting in the election of directors. The amendment of any of the above
provisions of our certificate of incorporation would require approval by holders
of at least two-thirds of the outstanding common stock.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is United Missouri
Bank of Kansas City. United Missouri Bank's telephone number for stockholder
inquiries is (800) 884-4225.

                        SHARES ELIGIBLE FOR FUTURE SALE

     Immediately prior to this offering, there was no public market for our
common stock. Future sales of substantial amounts of common stock in the public
market could adversely affect the market price of the common stock. Upon
completion of this offering, we will have outstanding 27,261,201 shares of
common stock based upon shares outstanding at October 29, 1999, assuming no
exercise of outstanding options after October 29, 1999. All of the shares sold
in this offering will be freely tradable without restriction under the
Securities Act except for any shares purchased by our "affiliates" as that term
is defined in Rule 144 under the Securities Act. The remaining 22,646,201 shares
of common stock outstanding are all "restricted" shares under the Securities
Act.

     All restricted shares are subject to lock-up agreements with the
underwriters pursuant to which the holders of the restricted shares have agreed
not to sell, pledge or otherwise dispose of such shares for a period of 180 days
after the date of this prospectus. Hambrecht & Quist LLC may release the shares
subject to the lock-up agreements in whole or in part at any time with or
without notice. However, Hambrecht & Quist LLC has no current plans to do so.
The following table indicates approximately when the 22,646,201 shares of our
common stock that are not being sold in the offering but which will be
outstanding at the time the offering is complete will be eligible for sale into
the public market:

</TABLE>

     As of October 2, 1999, 1,950,000 shares were reserved for issuance under
our amended and restated 1998 equity incentive plan, of which options to
purchase 1,695,250 shares were then outstanding and options to purchase 286,667
shares were then exercisable. These shares are subject to lock-up agreements. We
intend to file, within 180 days after the date of this prospectus, a
registration statement under the Securities Act to register the 1,950,000 shares
under our 1998 equity incentive plan and the 200,000 shares of common stock
reserved for issuance under our employee stock purchase plan. Upon registration,
all of these shares will be freely tradable when issued, subject to Rule 144
volume limitations applicable to affiliates and lock-up agreements.

     In October 1999, we issued a warrant to purchase 500,000 shares of common
stock. The shares issuable upon exercise of this warrant will be eligible for
resale in October 2000 if the warrant is exercised on a cashless basis or one
year from the date of exercise if the warrant is exercised with cash. In each
case, resale of these shares will be subject to Rule 144 volume limitations.

     In general, under Rule 144, as currently in effect, a person, or persons
whose shares are aggregated, who has beneficially owned restricted shares for at
least one year, will be entitled to sell in any three-month period a number of
shares that does not exceed the greater of:

     - one percent of the then outstanding shares of the common stock, which
       will equal approximately 275,000 shares immediately after this offering,
       or

     - the average weekly trading volume of the common stock during the four
       calendar weeks preceding the date on which notice of the sale is filed
       with the SEC.

     Sales pursuant to Rule 144 are subject to requirements relating to manner
of sale, notice and availability of current public information about us. A
person, or persons whose shares are aggregated, who is not deemed to have been
one of our affiliates at any time during the 90 days immediately preceding the
sale and who has beneficially owned his or her shares for at least two years is
entitled to sell such shares pursuant to Rule 144(k) without regard to the
limitations described above.

RULE 701

     In general, under Rule 701, a TMNG employee, director, officer or
consultant who purchases shares from us in connection with a compensatory stock
or option plan or other written agreement before the effective date of the
offering is entitled to resell these shares 90 days after the effective date of
this offering in reliance on Rule 144, without having to comply with certain
restrictions, including the holding period, contained in Rule 144.

     The SEC has indicated that Rule 701 will apply to typical stock options
granted by an issuer before it becomes subject to the reporting requirements of
the Securities Exchange Act of 1934, along with the shares acquired upon
exercise of these options (including exercises after the date of this
prospectus). Securities issued in reliance on Rule 701 are restricted securities
and, subject to the contractual restrictions described above, beginning 90 days
after the date of this prospectus, may be sold by persons other than affiliates
subject only to the manner of sale provisions of Rule 144 and by affiliates
under Rule 144 without compliance with its one year minimum holding period
requirement.

LOCK-UP AGREEMENTS

     All of our officers and directors and holders of our common stock and
options to purchase common stock have agreed pursuant to "lock-up" agreements
that they will not offer, sell, contract to sell, pledge, grant any option to
sell, or otherwise dispose of, directly or indirectly, any shares of common
stock or securities convertible or exchangeable for common stock, or warrants or
other rights to purchase common stock for a period of 180 days after the date of
this prospectus without the prior written consent of Hambrecht & Quist LLC. We
have also entered into an agreement with Hambrecht & Quist LLC that we will not
offer, sell or otherwise dispose of our common stock until 180 days offer the
effective date of this offering.

</TABLE>


     The underwriting agreement provides that the obligations of the
underwriters are subject to the conditions precedent, including the absence of
any material adverse change in our business and the receipt of certificates,
opinions and letters from us, our counsel and independent auditors. The nature
of the underwriters' obligation requires that they purchase all shares of common
stock offered if any shares are purchased.

     The underwriters propose to offer the shares of common stock directly to
the public at the initial public offering price set forth on the cover page of
this prospectus and to certain dealers at such price less a concession not in
excess of $       per share. The underwriters may allow and such dealers may
reallow a concession not in excess of $       per share to certain other
dealers. After the initial public offering of the shares, the offering price and
other selling terms may be changed by the underwriters. We have been advised by
the representatives that the underwriters do not intend to confirm discretionary
sales in excess of seven percent of the shares of common stock offered by this
prospectus.

     Messrs. Nespola and Peck and Behrman Capital, II L.P. and Strategic
Entreprenuer Fund II, L.P. have granted to the underwriters an option,
exercisable no later than 30 days after the date of the effective date of this
offering to purchase up to 692,250 additional shares of common stock at the
public offering price, less the underwriting discount, set forth on the cover
page of this prospectus. To the extent that the underwriters exercise this
option, each underwriter will have a firm commitment to purchase approximately
the same percentage thereof which the number of shares of common stock to be
purchased by it shown in the above table bears to the total number of shares of
common stock offered in this offering. The stockholders will be obligated to
sell shares to the underwriters to the extent the option is exercised. The
underwriters may exercise the option only to cover over-allotments made in
connection with the sale of common stock offered in this prospectus.

     The following table shows the per share and total underwriting discounts
and commissions we will pay to the underwriters. These amounts are shown
assuming both no exercise and full exercise of the underwriters' over-allotment
option to purchase additional shares.

     We estimate that the total expenses of this offering, excluding
underwriting discounts and commissions, will be approximately $1.0 million.

     At our request, the underwriters will reserve up to 323,000 shares of
common stock to be issued by us and offered for sale, at the initial public
offering price, to directors, officers, employees, business associates and other
persons related to us. The number of shares of common stock available for sale
to the general public will be reduced to the extent that such individuals
purchase all or a portion of these reserved shares. Any reserved shares which
are not purchased will be offered by the underwriters to the general public.

     The underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.

     The offering of the shares is made for delivery when, as and if accepted by
the underwriters and subject to prior sale and to withdrawal, cancellation or
modification of the offering without notice. The underwriters reserve the right
to reject an order for the purchase of shares in whole or in part.

     TMNG and the stockholders who have granted the underwriters an
over-allotment option have agreed to indemnify the underwriters against
liabilities connected to this offering, including liabilities under the
Securities Act, and to contribute to payments the underwriters may be required
to make in respect thereof.

     Each of our executive officers, directors, stockholders and optionholders
has agreed that they will not, without the prior written consent of Hambrecht &
Quist LLC, offer to sell, contract to sell or otherwise sell, dispose of, loan,
pledge or grant any rights with respect to any shares of common stock, any
options or warrants to purchase any shares of common stock or any securities
convertible into or exchangeable for shares of common stock owned by them as of
the date of this prospectus or thereafter acquired directly by such holders or
with respect to which they have or hereafter acquire the power of disposition,
until the date 180 days following the date of this prospectus.

     In addition, we have agreed that we will not, without the prior written
consent of Hambrecht & Quist LLC, offer, sell or otherwise dispose of any shares
of common stock, options or warrants to acquire shares of common stock or
securities exchangeable for or convertible into shares of common stock until the
date 180 days following the date of this prospectus, except that we may issues
shares upon the exercise of options granted prior to the date hereof, and may
grant additional options under our stock option plans, provided that without the
prior written consent of Hambrecht & Quist LLC the additional options shall not
be exercisable during such period.

     Prior to this offering, there has been no public market for our shares. The
initial public offering price has been negotiated among or company and the
underwriters. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be our historical performance, estimates of our business
potential and earnings, prospects, an assessment of management and the
consideration of the above factors in relation to market valuation of companies
in related businesses.

     We have applied to have our common stock quoted on the Nasdaq National
Market under the symbol TMNG.


     Netroadshow Inc., a division of Yahoo!, was utilized in connection with
this offering. Netroadshow is a provider of electronic roadshow presentations
that take the place of institutional one on one meetings. Netroadshow is not
receiving an allocation of the shares of common stock to be sold in this
offering.


     The representatives may over-allot or effect transactions which stabilize,
maintain or otherwise affect the market price of the common stock at levels
above those which might otherwise prevail in the open market, including by
entering stabilizing bids, effecting syndicate covering transactions or

                                       71
<PAGE>   73

imposing penalty bids. A stabilizing bid means the placing of any bid or
effecting of any purchase, for the purpose of pegging, fixing or maintaining the
price of the common stock. A syndicate covering transaction means the placing of
any bid on behalf of the underwriting syndicate or the effecting of any purchase
to reduce a short position created in connection with the offering. A penalty
bid means an arrangement that permits the underwriters to reclaim a selling
concession from a syndicate member in connection with the offering when shares
of common stock sold by the syndicate member are purchased in syndicate covering
transactions. These activities by the underwriters may stabilize, maintain or
otherwise affect the market price of the common stock. As a result, the price of
the common stock may be higher than the price that otherwise might exist in the
open market. Such transactions may be effected on the Nasdaq National Market, in
the over-the-counter market, or otherwise. Stabilizing, if commenced, may be

                          INDEPENDENT AUDITORS' REPORT

To the Board of Directors of
The Management Network Group, Inc.
Overland Park, Kansas

     We have audited the accompanying consolidated balance sheets of The
Management Network Group, Inc. and subsidiaries (the "Company") as of January 2,
1999 and December 31, 1997 and the related consolidated statements of income and
comprehensive income, stockholders' equity (deficiency in assets) and cash flows
for the years ended January 2, 1999, December 31, 1997 and 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company as of January 2,
1999 and December 31, 1997, and the results of their operations and their cash
flows for the years ended January 2, 1999, December 31, 1997 and 1996 in
conformity with generally accepted accounting principles.

     As discussed in Note 2 to the consolidated financial statements, the
Company retroactively changed its method of accounting for stock based
compensation to non-employees.

                       THE MANAGEMENT NETWORK GROUP, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 (INFORMATION FOR THE NINE MONTHS ENDED OCTOBER 3, 1998 AND OCTOBER 2, 1999 IS
                                   UNAUDITED)

1. ORGANIZATION

     NATURE OF OPERATIONS -- The Management Network Group, Inc. ("TMNG" or the
"Company") was formed on April 1, 1993 as a management consulting firm
specializing in global competitive telecommunications. Primary services include
serving wireless and wireline communications carriers in all industry segments,
and the technology and investment firms that support the telecommunications
industry. A majority of the Company's revenues are to customers in the United
States, however the Company also provides services to customers in the United
Kingdom, Canada, Australia and other foreign countries. The Company's business
is international in scope with corporate offices in Kansas City.

     RECAPITALIZATION -- On February 12, 1998, TMNG entered into a series of
transactions that resulted in a leveraged recapitalization (the
"recapitalization") of the Company. Prior to the recapitalization, the Company
made distributions totaling approximately $4.7 million to its stockholders and
all stockholders' notes receivable were paid off. The recapitalization included
the following transactions:

     - All authorized non-voting common stock was converted to voting common
       stock and the Company declared a 3,272.73-for-one stock split resulting
       in total authorized shares of 30 million with 22.5 million issued and
       outstanding. In connection with this stock split, the Company changed its
       par common stock to no par common stock. All historical share data has
       been retroactively restated for the effect of the stock split.

     - Behrman Capital II, LP ("Behrman") organized Behrman Capital TMNG, Inc.
       ("NEWCO") with contributed capital of $20.0 million and Behrman owning
       100% of NEWCO capital stock. NEWCO was formed as a transitory corporation
       solely for the purpose of effecting the recapitalization and has not
       carried on any activities to date other than those incident to its
       formation and the recapitalization.

     - Behrman exchanged 100% of its NEWCO stock for 13.5 million newly issued
       shares of TMNG common stock. NEWCO was then merged with and into TMNG
       with TMNG as the surviving corporation, at which time TMNG changed its
       income tax status to a subchapter "C" corporation from an subchapter "S"
       corporation. Offering costs of approximately $3.1 million were charged
       against additional paid-in capital at the time of the merger.

     - TMNG entered into a senior bank credit facility that provided $24.0
       million in term loans and a $5.0 million revolving credit facility from a
       syndicate of banks. TMNG utilized the funds provided by the credit
       facility and the proceeds from the merger with NEWCO to acquire 13.5
       million shares of common stock from existing stockholders (as of December
       31, 1997) for an aggregate cost of approximately $38.7 million. Such
       treasury shares were then retired. The costs to enter into the credit
       facility of approximately $500,000, were capitalized.

     The Company accounted for this series of transactions as a financial
restructuring/ recapitalization requiring continuation of the historical cost
basis.

     PRINCIPLES OF CONSOLIDATION -- The consolidated statements include the
accounts of TMNG and its wholly-owned subsidiaries, The Management Network Group
Europe Ltd. ("TMNG-Europe"), formed on March 19, 1997, based in the United
Kingdom, The Management Network Group Canada Ltd. ("TMNG-Canada"), formed on May
14, 1998, based in Toronto, Canada and TMNG.com, Inc., formed in June 1999. All
significant intercompany accounts and transactions have been eliminated in
consolidation.

 (INFORMATION FOR THE NINE MONTHS ENDED OCTOBER 3, 1998 AND OCTOBER 2, 1999 IS
                                   UNAUDITED)

     FISCAL YEAR -- Effective January 1, 1998, the Company adopted a 52/53 week
fiscal year, changing the year end date from December 31, to the Saturday
nearest December 31. The fiscal year ended January 2, 1999 had 52 weeks and is
referred to herein as fiscal year 1998. All references herein for fiscal years
1997 and 1996 represent the years ended December 31, 1997 and December 31, 1996,
respectively. TMNG-Europe and TMNG-Canada maintain year end dates of December
31.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     CONTRACTS -- The Company enters into both time and materials and fixed
price contracts with its customers. A substantial majority of TMNG's contracts
are based upon time and materials with a not to exceed total contract price.
Under a time and materials contract the customer pays a negotiated daily rate
for all services performed plus expenses incurred. Under a fixed price contract
the customer pays a predetermined fixed price for all services performed
regardless of the professional time required. Fixed price contracts generally
involve immaterial amounts and are of short duration.

     Prior to January 3, 1999 TMNG subcontracted with several companies (five of
which were related parties to TMNG through certain common ownership or are owned
by employees of TMNG) to provide consultants acting as independent contractors
to render the services required under the customer contracts. These subcontracts
were on a time and materials basis, contained confidentiality/noncompete
provisions and could be terminated by either party on 30 days prior notice.

     REVENUE RECOGNITION -- Time and materials service revenues and related time
and materials service costs are recorded in the period in which the service is
performed. Fixed price service contract revenues and related costs are
recognized upon contract completion under the completed contract method.

     CASH -- Cash includes cash on hand and cash in bank and is stated at cost,
which approximates market.

     PROPERTY AND EQUIPMENT -- Property and equipment are stated at cost less
accumulated depreciation and amortization. Depreciation is based on the
estimated useful lives of the assets and is computed using the straight-line
method. Asset lives range from three to seven years for computers and equipment.
Leasehold improvements are capitalized and amortized over the life of the lease.

     Maintenance and repairs are charged to expense as incurred. The cost and
accumulated depreciation applicable to assets retired are removed from the
accounts and the gain or loss on disposition is recognized in income.

     INTANGIBLE ASSETS -- Deferred financing costs are capitalized and amortized
over the term of the related credit facility using the straight-line method
which approximates the effective interest rate method. Accumulated amortization
was approximately $106,000 at January 2, 1999.

     LONG-LIVED ASSETS -- The Company, using its best estimates based on
reasonable and supportable assumptions and projections, reviews for impairment
long-lived assets and certain identifiable intangibles to be held and used
whenever events or changes in circumstances indicate that the carrying amount of
its assets might not be recoverable when compared to an estimate of future
undiscounted net cash flows expected to result from the use of these assets.
Management has concluded no financial statement adjustment is currently
required.

                       THE MANAGEMENT NETWORK GROUP, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 (INFORMATION FOR THE NINE MONTHS ENDED OCTOBER 3, 1998 AND OCTOBER 2, 1999 IS
                                   UNAUDITED)

     ADVERTISING COSTS -- Advertising costs are expensed as incurred.
Advertising expense charged to operations totaled approximately $57,000,
$115,000, and $101,000 for 1996, 1997, fiscal year 1998, respectively.

     INCOME TAXES -- As described in Note 1, the Company converted to a
subchapter "C" corporation for income tax reporting purposes effective February
12, 1998. Deferred tax liabilities of approximately $1.1 million were recorded
on February 12, 1998, in conjunction with the conversion, for the cumulative
temporary differences (see Note 7). The Company recognizes a liability or asset
for the deferred tax consequences of temporary differences between the tax basis
of assets or liabilities and their reported amounts in the financial statements.
A valuation allowance is provided when, in the opinion of management, it is more
likely than not that some portion or all of a deferred tax asset will not be
realized.

     Prior to February 12, 1998, the Company elected to be treated as a
subchapter "S" corporation under the Internal Revenue Code and thus was treated
substantially as a partnership for income tax purposes. Accordingly, until the
time of conversion to a subchapter "C" corporation, the individual stockholders
were responsible for their proportionate share of the corporate taxable income
or loss for federal and state income tax reporting purposes.

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

     FOREIGN CURRENCY TRANSACTIONS AND TRANSLATION -- The 1997 and fiscal year
1998 consolidated financial statements include TMNG -- Europe (located in the
United Kingdom). The fiscal year 1998 consolidated financial statements also
include TMNG -- Canada. Both entities conduct business primarily denominated in
their respective local currency. Assets and liabilities have been translated to
U.S. dollars at the period-end exchange rate. Income and expenses have been
translated at exchange rates which approximate the average of the rates
prevailing during each period. Translation adjustments are reported as a
separate component of other comprehensive income in the consolidated statements
of stockholders' equity. Realized and unrealized exchange gains and losses
included in results of operations were insignificant for all periods presented.

     STOCK-BASED COMPENSATION -- The Company accounts for stock based
compensation for employees in accordance with the provisions of Accounting
Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations and for stock-based compensation for
non-employees in accordance with Statement of Financial Accounting Standards
("SFAS") No. 123, "Accounting for Stock-Based Compensation."

     In connection with the planned registration of the Company's common stock
with the Securities and Exchange Commission, the Company has retroactively
adopted a new method of accounting for stock based compensation issued to
certain non-employees. The Company has recognized compensation expense based on
the fair market value of the options in accordance with EITF 96-18. Previously,
the Company accounted for such options under the provisions of APB No. 25, and
accordingly, did not recognize any expense. The accompanying 1998 consolidated
financial statements have been restated for this accounting change.

     NET INCOME PER SHARE -- Basic net income per share is computed by dividing
net income by the weighted average number of common shares outstanding for the
period. Diluted earnings per share reflects the potential dilution of securities
by adding other common stock equivalents, including

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 (INFORMATION FOR THE NINE MONTHS ENDED OCTOBER 3, 1998 AND OCTOBER 2, 1999 IS
                                   UNAUDITED)

stock options, in the weighted average number of common shares outstanding for a
period, if dilutive.

     DERIVATIVE FINANCIAL INSTRUMENTS -- The Company enters into interest rate
caps to manage exposure to interest rate volatility. The Company does not enter
into derivative financial instruments for speculative or trading purposes. The
costs of interest rate cap agreements are included in interest expense ratably
over the lives of the agreements. Payments to be received as a result of the cap
agreements are recorded as a reduction of interest expense.

     RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS -- The Company recently adopted
SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information." SFAS No. 131 establishes standards for reporting information about
operating segments, products and services, geographic areas and major customers.

     NEW ACCOUNTING STANDARDS -- The FASB recently issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133 was
amended by SFAS no. 137 which requires adoption of the SFAS requirements for
fiscal years beginning after June 15, 2000. This standard establishes accounting
and reporting requirements for derivative financial instruments and hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the statement of financial position and measure those
instruments at fair value. In the opinion of management, the effect of adoption
of this standard will not have a material impact to operating results of the
Company.

     PRO FORMA INFORMATION -- Pro forma information included in the consolidated
statements of income and comprehensive income is unaudited and included to
reflect the pro forma effect of providing income taxes on previously untaxed
subchapter "S" net income. This effect is calculated as follows:

          Pro forma income tax expense -- assumed 40% effective tax rate.

        Pro forma basic and diluted common shares -- include the effect of
        common share issuance and stock option exercise in accordance with SFAS
        No. 128, "Earnings per Share."

     FAIR VALUE OF FINANCIAL INSTRUMENTS -- The fair values of asset and
liability financial instruments approximate the carrying values.

     RECLASSIFICATIONS -- Certain prior period financial statement balances have
been reclassified to conform to the current period presentation.

     As of January 2, 1999, the Company had a $29.0 million secured credit
facility, as amended, with substantially all assets of the Company pledged as
collateral. The $29.0 million credit facility, which expires through December
2003, includes two $12.0 million term loans and a $5.0 million revolving credit
facility. Borrowings against the revolving credit facility are limited to 85% of
eligible accounts receivable as defined in the credit facility agreement.

     Interest is payable quarterly as follows:

</TABLE>

     The weighted average interest rate for the revolving line of credit was
9.59% in fiscal year 1998.

     The terms of the secured credit facility require the Company to maintain
certain financial ratios and observe additional restrictive covenants the most
restrictive of which preclude the payment of dividends and limit capital
expenditures. It is management's belief that the Company was in compliance with
all covenants as of January 2, 1999.

     The fair value of long-term debt approximates the carrying value as of
January 2, 1999.

6. DERIVATIVE FINANCIAL INSTRUMENTS

     As a requirement of the secured credit facility agreement, in March 1998
the Company purchased an interest rate cap agreement from a bank counterparty
with decreasing notional amounts in conjunction with specified debt principal
payments. The interest rate cap agreement was entered into to partially offset
the variable rate characteristics of $12.0 million in term loans. The notional
amount was $12.0 million as of January 2, 1999. The cap agreement was effective
March 13, 1998 and terminates on March 30, 2001. The agreement caps the floating
interest rate exposure on outstanding debt up to the notional amount of the
agreement at 8.1875%.

     The Company believes its exposure to potential loss due to counterparty
nonperformance is minimized primarily due to the relatively strong credit
ratings of the bank counterparty and due to the size and diversity of the
counterparty bank. The interest rate agreement is subject to market risk to the
extent that market rates for similar instruments decrease and the Company
terminates the hedge prior to maturity.

     A valuation allowance has been established for the Company's deferred
income tax asset related to the future benefit of net operating losses related
to TMNG -- Europe, as management cannot assess the likelihood that the future
tax benefit will be realized. An allowance of $134,000 has been recorded as of
January 2, 1999.

     The Company has foreign net operating loss carryforwards totaling
approximately $447,000 at January 2, 1999. The utilization of such net operating
loss carryforwards is restricted to the earnings of specific foreign
subsidiaries.

8. OPERATING LEASES

     The Company leases office facilities and certain automobiles under
non-cancelable operating leases expiring at various dates through August 2003.
Total rental expense was approximately $17,000, $27,000 and $40,000 for 1996,
1997 and fiscal 1998, respectively. As of January 2, 1999, the future minimum
payments under operating leases are as follows (amounts in thousands):

9. STOCK OPTION PLAN

     In 1998, 1,950,000 shares of the Company's Common Stock were authorized for
issuance under the Company's 1998 Equity Incentive Plan and 1998 Consultant
Equity Incentive Plan (the "Plans"). The Plans provide the Company's Common
Stock for the granting of incentive stock options and nonqualified stock options
to employees, and nonqualified stock options to employees, directors and
consultants. Incentive stock options are granted at an exercise price of not
less than

fair value per share of the common stock on the date of grant as determined by
the board of directors. Vesting and exercise provisions are determined by the
board of directors. Options granted under the Plans generally become exercisable
over a three to four year period beginning on the date of grant. Options granted
under the Plans have a maximum term of ten years. Subsequent to January 2, 1999,
the Company combined both plans into the 1998 Equity Incentive Plan.

</TABLE>

     The Company applies APB Opinion No. 25 ("APB 25") and related
interpretations in accounting for its stock option grants to employees and
certain non-employees. Options granted prior to December 8, 1998 were issued at
fair value. Options granted subsequent to December 7, 1998 were issued at less
than fair value. In connection with APB 25 grants issued in fiscal year 1998,
the Company recorded unearned compensation of $305,000 representing the
difference between the exercise price and the fair value of the common stock on
the dates such stock options were granted. Such amount is being amortized by
charges to operations on a graded vesting method over the corresponding vesting
period of each respective option, generally three years. Compensation expense
for fiscal year 1998 was insignificant due to the short period the grants with
unearned compensation were outstanding.

     The Company accounts for its stock option awards to independent contractors
and other non-employees in accordance with the fair value measurement provision
of SFAS No. 123. Consequently, the cost of these options are recognized in the
current and future reporting periods based on the fair value at the end of each
period. The fair value of each option grant during fiscal year 1998 was
estimated on the date of grant using the Black-Scholes option pricing model with
the following assumptions:

<TABLE>
<S>                                                           <C>

Expected dividend rate......................................             0%
</TABLE>

The Company recognizes compensation cost over the vesting periods. These options
have resulted in equity related charges to operations of approximately $261,000
for fiscal year 1998. These expenses have been allocated among various expense
categories.

     If compensation cost for the Company's APB 25 grants had been determined
based upon the fair value at the grant date, consistent with the Black-Scholes
option pricing methodology using the

10. RELATED PARTY TRANSACTIONS

     Two members of the TMNG board of directors are also directors of a customer
with which TMNG does business. During fiscal year 1998 the Company earned
revenues from this customer of approximately $330,000. Receivables from this
customer at January 2, 1999 were approximately $275,000. Additionally, venture
funds affiliated with TMNG's majority shareholder hold shares of preferred stock
of this customer that are convertible into approximately 25% of the customer's
outstanding common stock.

     Through January 2, 1999 TMNG subcontracted with five companies owned by
certain stockholders and employees of TMNG. These companies provided consultants
(acting as independent contractors) to TMNG to render consulting services to
TMNG customers. Effective January 3, 1999, TMNG contracts directly with
consultants. Total services received from these companies was approximately $7.8
million, $9.6 million and $14.9 million in 1996, 1997 and fiscal 1998,
respectively, and are included in cost of services in the statements of income
representing the fair value of the services provided. Included in accounts
payable at December 31, 1997 and January 2, 1999 are balances due for such
services of approximately $565,000 and $332,000, respectively.

     During 1996, 4,500,000 shares of treasury stock (non-voting) were purchased
by shareholders of the Company for cash of $50,000 and notes receivable of
$500,000. Such notes matured beginning January 1998 through April 1998 with
interest rates ranging from 5.2% to 7.0%. The outstanding balance on the notes
receivable at December 31, 1996 and 1997 are presented within stockholders'
equity as they represent receivables due from the sale of common stock. Included
in interest income is approximately $16,000, $6,000 and $7,000 in 1996, 1997 and
fiscal year 1998, respectively, related to these notes. As described in Note 1,
the notes were retired on February 12, 1998.

     On February 10, 1996, the Company issued options to acquire 2.25 million
shares of non-voting common stock at an exercise price of $0.12 per share
(estimated fair value at date of grant). The options were to be exercised prior
to June 30, 1997. The options were exercised on June 29, 1996, and are included
in the aforementioned sale of treasury stock.

     During 1996, 1997 and fiscal year 1998 TMNG made payments of approximately
$213,000, $200,000 and $77,000 respectively, to a company owned by a significant
stockholder of TMNG. In

addition, TMNG made a payment of $100,000 in 1997 to a stockholder. Such
payments were for services rendered under consulting agreements between TMNG and
the respective affiliated company and/or shareholder. These expenses were
classified as selling, general and administrative in the accompanying statements
of income and comprehensive income.

     During 1996 and 1997 TMNG incurred interest expense on notes and
distributions payable of approximately, $136,000 and $30,000, respectively, for
certain related parties. The interest rate applied was 7.0%.

11. CONTINGENCIES

     During 1997, one of the Company's customers entered Chapter 11 of the
bankruptcy code. According to the bankruptcy code, certain payments made within
a specified period of time prior to the date of the bankruptcy filing and
payments made subsequent to the date of the bankruptcy filing which are not
previously authorized, could be declared "preference payments". Under certain
conditions, preference payments could be required to be remitted to the
bankruptcy trustee for satisfaction of general creditor claims. During 1998, the
bankruptcy trustee filed suit against the Company for preferential payments
received prior to and subsequent to the bankruptcy filing, and related damages
of approximately $1.9 million. The total amount of payments received from this
customer during the specified preference period aggregated approximately
$320,000 and which may be declared preference payments. In the opinion of
management, resolution of this legal action will not have a material adverse
effect on the Company's consolidated results of operations, cash flows or
financial position.

     During 1997, the Company discovered that its TMNG-Europe general manager
and director had drawn Company funds without authorization. The director
resigned from TMNG-Europe during the year ended December 31, 1997 and claimed
that he was owed unpaid remuneration and reimbursable expenses. During 1998, the
Company received approximately $92,000 from the former director in settlement of
the claim.

     The Company may become involved in various legal and administrative actions
arising in the normal course of business. These could include actions raised by
taxing authorities challenging the employment status of consultants utilized by
the Company. While the resolution of any of such actions or the matter described
above may have an impact on the financial results for the period in which it is
resolved, the Company believes that the ultimate disposition of these matters
will not have a material adverse effect upon its consolidated results of
operations, cash flows or financial position.

12. SUBSEQUENT EVENTS

     On August 27, 1999, the board of directors approved, subject to stockholder
approval, the amendment of the Company's Certificate of Incorporation, which
included, among other things, reincorporation of the Company in the State of
Delaware and a change in the par values and total number common stock and
preferred stock of which the Company is authorized to issue. The total number of
shares of common stock which the Company has authority to issue is 50 million
with par value of $0.001 per share. The total number of shares of preferred
stock which the Company has authority to issue is 10 million with par value of
$0.001 per share.

     On September 7, 1999, the Board of Directors authorized the Company to
proceed with an initial public offering of its common stock.

13. REVERSE STOCK SPLIT AND WARRANT GRANT

     Effective November 8, 1999 the Company amended its Certificate of
Incorporation to give effect for a 1-for-2 reverse stock split for all
authorized shares of voting and non-voting common stock. All share and per share
data has been retroactively adjusted to reflect this reverse split.

     On October 29, 1999, the Company issued a significant customer a warrant to
purchase 500,000 shares of common stock at an exercise price of $2.00 per share.
The expected fair value of this warrant is approximately $5.2 million assuming
its expected life is 3 years and will be recognized as future equity related
charges in operations. Additionally on October 29, 1999, the Company reached an
agreement in principle with this customer under which such customer will commit
to $22 million of consulting fees over a three year period.

14. INTERIM FINANCIAL STATEMENTS (UNAUDITED)

Basis of presentation:

     The unaudited interim condensed consolidated financial statements reflect
all adjustments which are, in the opinion of management, necessary to a fair
statement of the results of operations for the nine month periods ended October
3, 1998 and October 2, 1999. All such adjustments are of normal, recurring
nature. The interim results of operations shown are not necessarily indicative
of results that may be expected for the entire fiscal year.

     The unaudited interim consolidated financial statements should be read in
conjunction with the 1998 audited consolidated financial statements.

Stock based compensation:

     During the nine month period ended October 2, 1999, the Company granted
approximately 620,500 stock options to employees and non-employee consultants at
a weighted average exercise price of $2.00 per share and cancelled 25,000 stock
options previously issued to employees and consultants. During the same period
the Company recorded unearned compensation of $6.1 million. Compensation expense
related to all stock options was $2.3 million during the period. The balance of
outstanding options at October 2, 1999 was 1,695,250.

     During the nine months ended October 2, 1999, the Company issued 71,000
shares of common stock representing bonus compensation to certain employees. The
Company calculated compensation expense related to these shares at the fair
value of the shares at the date of issuance. Accordingly, compensation expense
of $441,000 was charged to operations.

Deferred stock issuance costs:

     During the nine months ended October 2, 1999, the Company deferred costs of
approximately $527,000 incurred in connection with an initial public offering of
its common stock. This amount is included in Other assets at October 2, 1999 and
includes specific incremental costs directly attributable to the actual
offering. This amount will be charged against the gross proceeds of the offering
at closing.

Share and per share amounts:

     All share and per share amounts included in the unaudited interim
consolidated financial statements have been presented giving effect to a planned
1-for-2 reverse stock split.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law allows for the
indemnification of officers, directors and any corporate agents in terms
sufficiently broad to indemnify such persons under certain circumstances for
liabilities (including reimbursement for expenses incurred) arising under the
Securities Act. Our certificate of incorporation and our bylaws provide for
indemnification of our directors, officers, employees and other agents to the
extent and under the circumstances permitted by the Delaware General Corporation
Law. We have also entered into agreements with our directors and executive
officers that require us among other things to indemnify them against certain
liabilities that may arise by reason of their status or service as directors and
executive officers to the fullest extent permitted by Delaware law. We have also
purchased directors and officers liability insurance, which provides coverage
against certain liabilities including liabilities under the Securities Act.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     (a) Within the past three years, we have issued and sold the following
unregistered securities:

          (1) In February, 1998, we issued and sold an aggregate of 13,500,000
     shares of common stock to our officers and directors and to certain other
     individuals for an aggregate purchase price of $19,980,000.

          (2) We issued and sold an aggregate of 71,201 shares of common stock
     to certain individuals in 1999 as of October 2, 1999.

          (3) Since our inception, we have granted options to purchase 1,720,250
     shares of common stock to directors, employees and consultants under our
     1998 Equity Incentive Plan at exercise prices ranging from $1.48 to $2.00
     per share. As of October 2, 1999, options to purchase 1,695,250 shares
     remain outstanding.


          (4) In October 1999, we issued a warrant to purchase 500,000 shares of
     our common stock to Williams Communications. The exercise price is $2.00
     per share.


     The sales and issuances of securities in the transactions described above
were deemed to be exempt from registration under the Securities Act in reliance
upon Section 4(2) of the Securities

                                      II-1
<PAGE>   95

Act, Regulation D promulgated thereunder, or Rule 701 promulgated under Section
3(b) of the Securities Act, as transactions by an issuer not involving any
public offering or transactions pursuant to compensatory benefit plans and
contracts relating to compensation as provided under Rule 701. The recipients of
securities in each transaction represented their intentions to acquire the
securities for investment only and not with a view to or for sale in connection
with any distribution thereof and appropriate legends were affixed to the
securities issued in such transactions. All recipients had adequate access to
information about us through their relationship with us.

     (b) There were no underwritten offerings employed in connection with any of
the transactions set forth in Item 15(a).

ITEM 17. UNDERTAKINGS

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

     We hereby undertake that:

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

          (b) 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.
