ITEM 1. BUSINESS
 
OVERVIEW
 
     Diamond Technology Partners Incorporated (the "Company" or "Diamond") is a
management consulting firm that synthesizes business strategy with IT to create
innovative "digital strategies" for leading national and multinational
corporations. Diamond was founded upon a belief that effective digital
strategies can be conceived only when strategy and technology are considered in
tandem, not in sequence. Once conceived, the Company believes such strategies
must be implemented rapidly in order to maximize competitive benefits.
 
     The Company works with its clients to help them understand, develop and
then manage the implementation of digital strategies. The Company leads its
clients through a process which broadens their understanding of the ways IT can
be used strategically to gain competitive advantage in their markets. Diamond's
professionals, working closely with client personnel, perform thorough analyses
of the client's current business with a focus on alternative IT-driven business
strategies. When an appropriate strategy has been developed, Diamond's
professionals provide important management oversight of the strategy
implementation process, which generally includes design, deployment and
integration of IT solutions together with modification of business processes and
organizational structure. Throughout the entire process, Diamond transfers
relevant knowledge to the client organization.
 
INDUSTRY BACKGROUND
 
     Many leading corporations face a rapidly changing business environment and
new competitive pressures. Success in the midst of change requires mastering
increasing complexity, adapting products and services to dynamic market
conditions, reducing costs and improving quality. IT is increasingly being used
in a variety of innovative, strategic ways to create new businesses, products
and services, open new sales and marketing channels and provide cost reduction
and time-to-market advantages. For instance, technology has enabled book
retailing to be accomplished in cyberspace, with no physical retail presence.
Stocks and bonds can be purchased and sold on a home computer at negligible
cost. Packages can be delivered overnight, with each step in the journey
traceable through the Internet. As IT takes on a more prominent role as a driver
of business strategy, it also creates new competitors, eliminates established
sales and marketing channels, and shortens research and development cycles.
 
     Business leaders no longer view IT solely as a support function, but often
struggle to incorporate the potential that technology holds as a driver of
business strategies. Many senior executives realize that they do not have the
internal expertise and capability to define and address challenges presented by
blending strategy and IT. Historically, these organizations have had two
options: (i) hire two separate firms (a strategic management consultant to
define the problem and a systems integrator to provide a solution) or (ii) hire
a full-service firm that offers both management consulting and systems
integration services.
 
     When hiring separate firms, a management consultant first works with the
senior management of the company to develop a new business strategy. Senior
management then hires a systems integrator to determine and develop the
information systems to support the business strategy. The Company believes this
approach is inherently flawed, increases overall project cost and risk, and
threatens the integrity of the strategy. Traditional management consultants
typically do not have the in-depth understanding of technology needed to
formulate digital strategies. In addition, the transition to a systems
integrator, which often lacks a common vision of the business objective,
requires additional time and resources. The second alternative is to hire a
full-service firm that offers both management consulting and systems integration
services. However, these services are typically delivered by separate practices
or business units within the same firm. This alternative creates two problems:
economic incentive to sell other proprietary products and services that may not
be required, and transition issues similar to those experienced in hiring two
firms.
 
     The Company believes that the current business environment provides an
opportunity for a firm that offers high-level strategic management consulting
with an in-depth understanding of technology. In particular,
 
                                        3
<PAGE>   4
 
management believes business leaders will increasingly seek this expertise from
objective consultants unaffected by commercial interests in software, hardware
or IT services practices.
 
THE DIAMOND ADVANTAGE
 
     Diamond was founded with the objective of providing superior client
solutions by creating a common business culture in which strategic consulting
and IT expertise are optimally integrated to design and deliver digital
strategies. The Diamond solution is distinguished by the combination of three
essential characteristics: (i) the synthesis of business strategy and
technology, (ii) solution objectivity, and (iii) accountability for the delivery
of benefits.
 
  The Synthesis of Business Strategy and Technology
 
     A digital strategy combines business strategy and technology in innovative
new ways. The Company recognizes that technology does not merely support
business, it creates business. Diamond simultaneously provides expertise in
strategy consulting, business processes and IT, enabling the Company to identify
digital strategy opportunities for its clients that might not otherwise be
considered by a management consulting firm or a systems integration firm. The
Company's services are delivered through small, experienced and
multidisciplinary teams that work collaboratively with the client to create an
environment in which knowledge and skills are constantly shared. This transfer
of knowledge is of significant value to the client.
 
  Solution Objectivity
 
     A consulting firm that objectively advises on strategy cannot be in the
business of selling software, hardware, or the services of programmers. Diamond
has intentionally avoided entering into alliances that might influence, or be
perceived to influence, the strategy that it recommends to a client.
Furthermore, the Company does not offer systems integration programming services
that might bias its recommendation. Diamond believes this objectivity is
critical to its ability to address strategic issues and earn its clients' trust.
 
  Accountability for the Delivery of Benefits
 
     In the digital age, business environments change so rapidly that the same
team that develops a business strategy must be held accountable for the delivery
of its benefits to the client. Rather than defining the success of an engagement
by the delivery of a strategy or application, Diamond measures success in terms
of the project's accomplishment of stated strategic goals such as return on
investment or reduction in manufacturing cycle times. Because the Diamond
solution is delivered to the client by the same multidisciplinary team that
created the strategy, the time-to-market and other transition risks associated
with these projects are reduced.
 
DIAMOND'S GROWTH STRATEGY
 
     Diamond's goal is to become the leader in the design and delivery of
digital strategies. As a professional services firm, there are two primary
constituencies critical to the realization of this goal: the Company's
professionals and its clients. Accordingly, each of the following strategies
focuses on attracting, developing and retaining the Company's professionals and
clients.
 
  Attract and Retain Skilled Personnel
 
     The Company believes that its continued success and growth require it to
expand its base of highly skilled professionals. This emphasis on human
resources begins with the Company's recruitment of client-serving professionals
from the best business and technical schools, continues through the process of
training, developing and promoting promising professionals within the Company
and culminates in the sharing of equity in the Company as both an acknowledgment
of merit and a means of retention.
 
                                        4
<PAGE>   5
 
  Leverage Vertical Expertise
 
     The Company believes that its vertical market focus provides a scalable
structure for growth. Through a vertical focus in four key markets (insurance
and health care, telecommunications and energy, financial services, and consumer
products and services), the Company is able to offer digital strategies anchored
by an in-depth understanding of market-specific knowledge. The Company expects
the number of vertical markets on which it focuses to change and grow as the
Company's expertise and market demands evolve.
 
  Expand Client Relationships
 
     The Company seeks to develop strong relationships with clients that sustain
and grow repeat business. The access, contact and goodwill generated through its
existing client relationships afford the Company significant opportunities to
provide additional services and solutions. In addition, the Company plans to
continue investing in several sales and marketing activities designed to further
demonstrate the Company's capabilities to both new and existing clients. See
"-- Sales and Marketing."
 
  Deliver Services through Multidisciplinary Teams
 
     In order to maintain a differentiated service offering, the Company seeks
to develop and sustain a business culture that is common across all disciplines
in the organization. The Company seeks to promote its culture by exposing its
professionals to all of the various services that Diamond provides while further
developing skills in each professional's principal area of expertise.
 
  Nurture and Promote Intellectual Capital
 
     Diamond utilizes its accumulated knowledge and experience to provide
relevant intellectual capital to a given project and to develop innovative
solutions for its clients. The Company continuously seeks to identify and
disseminate new intellectual capital throughout its organization to keep abreast
of business and technology trends. Intellectual capital is provided by
individuals both within and outside the Company and incorporated into the
Company's practice and training.
 
  Market Diamond Brand Image
 
     Diamond intends to continue to invest in the development and maintenance of
its brand identity in the marketplace. The Company promotes its name and
credentials through publications, seminars, speaking engagements, media and
analyst relations, direct marketing, the World Wide Web and other efforts. The
Company believes that building a brand image facilitates the lead generation
process by raising awareness of the Company, and consequently, increasing the
number of opportunities to propose on new projects.
 
DIAMOND'S SERVICES
 
     The Company designs and manages the delivery of digital strategies. Diamond
leads a client through a process combining creative and analytical thinking with
an in-depth understanding of IT to enable the client to conceptualize its
business differently, and then designs and delivers a digital strategy. This is
fundamentally different than the traditional, sequential approach that addresses
strategy first, followed by development of new or revised IT solutions.
 
     A small project team of Diamond consultants with expertise in strategy,
business processes and IT works closely with the client throughout this process.
The phases which are included on any given client project, and the amount of
time spent on each phase vary greatly depending upon the scope of work and the
readiness of
 
                                        5
<PAGE>   6
 
the client organization to change. The Company's Service Delivery Process is
generally outlined in the following diagram:
 
                   [Diamond Service Delivery Process Graph]
 
  Executive Alignment
 
     The executive alignment segment of the process is designed to help the
client explore the new strategic possibilities of technology before determining
a strategy. This segment consists of three phases: learning, collaboration and
prototyping. Learning helps clients explore and understand the new strategic
possibilities of technology in order to set preliminary goals. Collaboration
gains consensus within the client's organization on these preliminary goals.
Prototyping tests the goals to ensure they are realistic and prioritizes them
based on desired results. This segment leads to the development of a digital
strategy to achieve a client's objectives.
 
  Strategy
 
     Based on the results of the executive alignment segment, a digital strategy
is then determined by the Company and the client. The strategy is a blueprint to
help the client reach its goal. When determining the strategy, the team further
evaluates the dynamics of the client's competitive and financial environments.
Importantly, specific performance goals and detailed deployment plans for the
new strategy are created, which constitute milestones by which the client can
readily measure results during the deployment phase. The deployment plans
developed in this phase correspond to the requirements of the project, but
generally include an organizational strategy, a process redesign strategy and an
IT strategy.
 
  Program Management
 
     The objective of the program management segment is to maintain focus on the
business value of the project throughout the implementation of the strategy.
While Diamond manages the implementation of digital strategies, it does not
provide programming services. The Company's collaborative approach utilizes the
client's IT staff for programming functions. In the event that a client's
organization is unable to provide such functions internally, Diamond
subcontracts to third-party software programmers or systems integrators selected
for their expertise. Diamond's program management services provide the
leadership and management needed to implement adjustments to the deployment plan
as needed to deliver a solution on time and within budget. Key variables managed
throughout this segment include project content, constituencies affected by the
project, knowledge transferred, risk associated with the project and resources
utilized.
 
     Program management services are delivered either as part of the
implementation of a strategy, or as a service by itself. As part of the
implementation of a strategy, program management consists primarily of three
phases: architecture, development and deployment. Architecture defines the
implementation of a new strategy, including its business and technical
components. Development involves the transfer of specific knowledge about new
technologies and processes to the client. Deployment consists of the management
of the implementation of the strategy using the client's IT management and
programming resources. When delivered
                                        6
<PAGE>   7
 
as a separate service, program management services are used to manage very
large, enterprise-wide initiatives, or to help a client regain control of a
project that has materially deviated from plan.
 
SALES AND MARKETING
 
     The principal sales activities of the Company are managed by senior
Partners. The senior Partners are responsible for building relations with senior
executives of existing and potential clients and for formulating and executing
the Company's sales and marketing strategy. The senior Partners call on existing
and potential clients, discuss potential engagements, negotiate the terms of
engagements, and direct the staffing and execution of consulting projects.
 
     The Company primarily sells its services to senior executives of national
and multinational corporations. Although every client relationship is unique,
the Company's client relationships to date generally have included multiple
projects. Diamond has divided its Partners into six vertical groups focused on
several industry sectors: insurance, health care, telecommunications, energy,
financial services, consumer products and services. The sales efforts in each
group are led by a senior Partner who is assigned revenue and profit
contribution responsibility. New projects are sought within each group from both
new prospects and existing clients. Each vertical group maintains a current list
of targeted prospects which are tracked on an ongoing basis by senior management
of the Company. Building on leads generated through the Company's marketing
programs, senior Partners engage in dialogue with client and prospect senior
management which can result in formal consulting engagements.
 
     The primary focus of the Company's marketing programs is to generate leads
through building relationships and educating client prospects about Diamond. The
Company has initiated a number of relationship-marketing programs designed to
complement, encourage and accelerate personal relationships. The Company builds
relationships both directly and on a collaborative basis with members of the
Diamond Network (see "-- Intellectual Capital") and through relationships with
certain third-party industry executives, called "client relationship executives"
(CREs). Members of the CRE program are typically semi-retired senior executives
with a wide network of contacts in a given industry. The Company currently has
eight CREs focusing in the telecommunications and energy, financial services,
and consumer products and services industries.
 
     Complementing the relationship-marketing programs are a variety of other
business development and marketing techniques used to communicate directly with
current and prospective clients, including publications, surveys, a promotion of
an upcoming book, newsletters, media and analyst relations, speeches and a
homepage on the World Wide Web. Three of the more substantive marketing efforts
include the publication of the business magazine, Context; the development and
publication of annual Digital Strategies Surveys; and a book focusing on digital
strategy. Each of these programs is designed to educate the market on the
opportunities of digital strategies, demonstrate the Company's intellectual
capital, and create an ongoing dialogue with client prospects.
 
     Context is a controlled-circulation magazine covering the growing
intersection of business and technology that is distributed quarterly to
approximately 32,000 senior executives (CEOs and their direct reports in the
United States). The Digital Strategy Surveys are a series of research that
provide benchmarks for senior executives facing the convergence of business
strategy and technology. "Unleashing the Killer App: Digital Strategies for
Marketing Dominance" is a book co-authored by a Diamond Partner and a member of
the Diamond Network and was published in the first quarter of fiscal 1999.
 
REPRESENTATIVE CLIENTS
 
     Diamond currently focuses on providing services to clients in several
industry sectors: insurance, health care, telecommunications, energy, financial
services, consumer products and services. The Company intends to expand the
industries in which it focuses as its expertise and market demands evolve.
 
                                        7
<PAGE>   8
 
     The following are examples of clients that are representative of the
Company's business:
 
  Insurance Company
 
     This multi-billion dollar specialty insurer initially engaged Diamond to
design strategies to sustain the superior revenue performance and growth in
shareholder wealth that it had experienced over the last several years. The
project commenced with a 1 1/2-day executive workshop where management explored
the potential impacts of technology on the company. The project then evolved
into the development of a model for a technology-based, customer-centric
strategy to reshape the company into a customer-focused business. Diamond was
then engaged to work with the client to assess the IT organization and develop
business, economic and technical architecture implementation plans. The plans
called for revamping the client's entire operations (including product
development, marketing, sales and service functions) in order to focus on the
customer using the Internet and other technologies. Diamond is currently working
with the client to create the first of a series of deployment plans to implement
the customer-centric strategy and realize the benefits. In concurrent projects,
Diamond reviewed the migration and consolidation requirements for the client's
benefits function, as well as defined criteria for the client to assess
potential outsourcing vendors.
 
  Energy Retailer
 
     Diamond was initially engaged to assist this investor-owned electric
utility in developing a new business that offered power from renewable sources
to consumers in newly deregulated markets. Diamond worked with the client to
develop a digital strategy that will differentiate the company by creating an
electronic dialogue with its customers over the Internet, track behaviors and
subsequently adapt to their specific desires over time. Diamond's relationship
with this client consists of five separate, but related, projects: (i) the
conduct of an economic viability study that explored technology and industry
trends affecting the ability of the client to reach retail and small-business
customers with renewable power, (ii) the development of the digital strategy and
business plan to secure the external funding needed, (iii) the development of a
fundable business strategy and technology/operations implementation plan, (iv)
the management of the technology and operations infrastructure roll-out,
including a network of third-party vendors, and (v) the ongoing counsel to the
client with respect to its efforts in shaping the rules of engagement in the
deregulated energy markets.
 
  Financial Services Company
 
     This large, middle-market commercial finance company identified technology
as a key factor in its plan to capitalize on attractive opportunities in the
emerging market made up of small- to mid-size borrowers. Diamond was selected to
work with the client as a result of contacts developed through the Diamond
Exchange, the Company's executive learning forum, and capabilities demonstrated
to the client on prior projects. Diamond's initial role was to develop a
technical architecture plan to effectively leverage the client's IT
infrastructure investment. This role expanded into the implementation of the new
technical architecture, as well as a project to help the client design an
intranet to facilitate corporate communications. This role evolved into the
exploration of a digital strategy to capitalize on the new small- to mid-size
market. The digital strategy project grew through three phases: (i) the
exploration with the client's senior management to discover various
opportunities offered by technology, (ii) the development of a working business
strategy and plan balanced with the operational capabilities of the client, and
(iii) the development of a sequence of implementation plans to realize the
benefits identified in the strategy.
 
INTELLECTUAL CAPITAL
 
     Consulting firms are notably knowledge-intensive organizations. In the
past, the existence of accumulated experience within a consulting firm was
enough to attract and retain clients. Today, information is more readily
accessible and the useful life of new knowledge is shortening. In recognition of
this trend, Diamond has developed programs to identify, capture and disseminate
intellectual capital from individuals both within and outside the Company.
 
                                        8
<PAGE>   9
 
  Knowledge Leaders
 
     The Company has created a career path for certain of its professionals who
desire to specialize in a particular area, such as technical architecture,
electronic commerce or supply-chain operations. Diamond refers to these
professionals as "knowledge leaders" within its organization. Knowledge leaders
are responsible for identifying new developments within their respective areas
of expertise and capabilities, and applying that knowledge to client projects
and within the organization. Diamond currently has four Partner-level knowledge
leaders and anticipates that more knowledge leaders will be added in the future.
 
  Diamond Exchange
 
     The Diamond Exchange is a series of executive learning forums that the
Company launched in February 1997. Senior executives ranging from CEOs to CIOs
are invited to participate in the Diamond Exchange. The Company provides its
paid-subscription members with innovative, leading-edge research to explore and
understand the strategic risks and opportunities of emerging technologies.
Diamond Exchange members meet three times a year to discuss current issues and
research findings, and their business implications. During these meetings,
Diamond provides the members of the Diamond Exchange with the opportunity to
discuss their issues with Diamond Network members and other business leaders.
There are also three smaller working sessions throughout the year. The
objectives of this program are threefold: (i) to help clients and prospects
learn and research the strategic possibilities of technology in the digital
future; (ii) to maintain and develop relationships with clients; and (iii) to
build intellectual capital and integrate it into the Company.
 
  Diamond Network
 
     The Diamond Network is a group currently comprised of 12 recognized
business and technology leaders associated with the Company. Members of the
Diamond Network provide Diamond with a set of skills that augment and enhance
the value that Diamond can provide to its clients. Diamond Network members
provide a source of intellectual capital, introduce the Company to prospective
clients, serve as faculty to the Diamond Exchange (see above), and participate
in client projects. Members are contractually committed to dedicate a certain
number of days to Diamond to support marketing, sales, and client work. Diamond
Network relationships are generally non-exclusive, two-year contracts. Members
are given a combination of stock options and per diem payments for services
provided to the Company or its clients on the Company's behalf. Current members

HUMAN RESOURCES AND CULTURE
 
     As of March 31, 1998 Diamond had 223 employees. Of these employees, 175
were client-serving professionals and 48 were management and administrative
personnel comprising marketing, human resources, finance, accounting, legal,
internal information systems and administrative support.
 
     The responsibilities of a Partner include client relationship development,
business development, client management, program management, thought leadership,
professional staff development and mentoring. Partners typically have ten to 20
years, or more, of experience.
 
  Culture
 
     Diamond believes its ability to simultaneously provide expertise in
strategy, business processes and IT is dependent upon its ability to develop and
sustain a business culture that is common across all disciplines in the
organization. Three primary elements comprise Diamond's culture: (i) an
environment that intellectually challenges its personnel through continuous
training and client work; (ii) consistency in compensation and career paths
across all disciplines and skill sets within the firm; and (iii) participation
by all employees in the continuing development and ownership of the firm. The
Company plans to further strengthen its culture through various policies and
programs and by continuing to increase promotions from within the organization.

  Recruiting
 
     The Company intends to grow primarily from within to maintain a strong
culture. The Company's success will depend on its ability to continue to
attract, retain and motivate highly skilled employees to support current
operations and future growth. The Company attributes its success in hiring these
people to its ability to provide individuals with competitive compensation,
multidisciplinary training and career development, attractive long-term career
advancement opportunities, small teams and a collaborative approach to
consulting.
 
     Although a significant number of the Company's current employees were hired
directly from other firms, a growing number of associates are being hired
annually from graduate business programs at many of the country's leading
universities. The Company also has a summer associate program that provides an
additional source of graduate business program hires. Over time, the Company
expects to hire a majority of its employees from these programs and, as a
result, the more senior levels will be filled from internal promotions.
 
  Training and Development
 
     The Company's training and professional development programs help it to
deliver high-quality services to its clients, as well as to attract and retain
highly skilled professionals. The Company has developed programs that ensure all
individuals have the opportunity to develop consulting, business and IT skills
throughout their careers. These programs reinforce Diamond's culture by exposing
all professionals to the various services Diamond provides while further
developing deep skills in each professional's principal area of expertise.
 
  Compensation
 
     The Company's compensation programs have been structured to attract and
retain highly skilled professionals by offering competitive base salaries
coupled with annual cash bonus opportunities. Equity is used at all levels
within the organization to provide long-term wealth creation opportunities and
to retain individuals through vesting provisions. Diamond believes that those
professional services firms able to offer equity will be more successful in
attracting and retaining talented individuals to their organizations.
 
     Individuals below the Partner level are awarded annual cash bonuses based
on their performance as it compares to their peers. Partners can receive an
annual bonus comprised of both cash and equity commensurate with their level of
responsibility and based on the overall performance of the Company. Non-
Partners are granted stock options at the time of hire and/or promotion, based
on their level. These options vest after three years. Partners buy stock and are
granted stock options upon being elected a Partner. Additional equity grants are
made in conjunction with movement through the Partner levels. Stock and options
issued to Partners vest annually over five years.
 
COMPETITION
 
     The Company's primary competitors include management consulting firms,
systems integrators and firms that provide both management consulting and
systems integration services. Many of the Company's competitors are
substantially larger than the Company and have significantly greater financial,
technical and marketing resources, greater name recognition and greater revenues
than the Company. Management believes that competition may increase from the
large traditional management consulting firms as these firms increase their use
of IT in their consulting services and enter the digital strategy market. The
Company believes that the principal criteria considered by prospective clients
when selecting a consulting firm to develop and implement digital strategies
include: scope of services, service delivery approach, technical and industry
expertise, perceived value, objectivity and a results orientation.
 
     Furthermore, the Company faces the additional challenge of competing for
and retaining the best personnel available in the digital strategy market. As
other firms enter the digital strategy market, the Company believes that its
client-serving professionals and employees may be targeted by other firms to
satisfy their own personnel needs.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
     The following information should be read in connection with the information
contained in the Consolidated Financial Statements and notes thereto appearing
elsewhere in this Annual Report on Form 10-K. This Annual Report on Form 10-K
contains forward-looking statements that involve risks and uncertainties. The
Company's actual results may differ materially from the results discussed in the
forward-looking statements (See Item 1. Business).
 
OVERVIEW
 
     Diamond is a management consulting firm that synthesizes business strategy
with IT to create innovative "digital strategies" for leading national and
multinational corporations. The Company has experienced substantial revenue
growth in its four years since inception, generating net revenues of $58.4
million from 65 clients during the twelve months ended March 31, 1998 (fiscal
1998). The Company had 175 client-serving professionals as of March 31, 1998.
 
     The Company's revenues are comprised of professional fees for services
rendered to clients which are billed either monthly or semi-monthly in
accordance with the terms of the client engagement. Prior to the commencement of
a client engagement, the Company and its client agree on fees for services based
upon the scope of the project, Diamond staffing requirements and the level of
client involvement. The Company recognizes revenues as services are performed in
accordance with the terms of the client engagement. Out-of-pocket expenses are
reimbursed by clients and offset against expenses incurred and are not included
in recognized revenues. Provisions are made for estimated uncollectible amounts
based on the Company's experience. Although the Company from time to time has
been required to make revisions to its clients' estimated deliverables, to date
none of such revisions has had a material adverse effect on the Company's
operating or financial results.
 
     The largest portion of the Company's costs consist primarily of
employee-related expenses for its client-serving professionals and other direct
costs, such as third-party vendor costs and unbilled travel costs associated
with the delivery of services to clients. The remainder of the Company's costs
are comprised of the expenses associated with the development of the business
and the support of its client-serving professionals, such as professional
development and recruiting, marketing and sales, and management and
administrative support. Professional development and recruiting expenses consist
primarily of recruiting and training costs. Marketing and sales expenses consist
primarily of the costs associated with the Company's development and maintenance
of its marketing materials and programs. Management and administrative support
expenses consist primarily of the costs associated with operations, finance,
information systems, facilities and other administrative support for project
personnel.
 
     The Company regularly reviews its fees for services, professional
compensation and overhead costs to ensure that its services and compensation are
competitive within the industry. In addition, Diamond periodically monitors the
progress of client projects with its clients' senior management. The Company
manages activities of its professionals by closely monitoring engagement
schedules and staffing requirements for new engagements. Because most of the
Company's client engagements are, and may be in the future, terminable by the
client without penalty, an unanticipated termination of a client project could
require the Company to maintain underutilized employees. While professional
staff must be adjusted to reflect active engagements, the Company must maintain
a sufficient number of senior professionals to oversee existing client
engagements and participate in the Company's sales efforts to secure new client
assignments.
 
RECENT DEVELOPMENTS
 
     The Company completed an offering of 3,000,000 shares of Class A Common
Stock in April 1998. In connection with this offering, the Company sold
approximately 650,000 shares of Class A Common Stock and the selling
shareholders sold approximately 2,350,00 shares of Class A Common Stock. Net
proceeds to the Company totaling approximately $16 million were realized in
April 1998.

</TABLE>
 
FISCAL 1998 COMPARED TO FISCAL 1997
 
     The Company's net income of $6.0 million during fiscal 1998 improved from
net income of $633,000 during fiscal 1997 as a result of increased revenues
combined with an improvement in the utilization of client-serving professionals,
partially offset by an increase in expenses required to support the Company's
growth during the period. The Company's net income in fiscal 1997 included net
losses for the first six months of the fiscal year, which resulted primarily
from the loss of two projects as a result of clients' cancellations of business
initiatives. The Company responded to these project cancellations and the
resulting business circumstances during the quarter ended September 30, 1996, by
reducing spending levels, including the elimination of its bonus programs for
fiscal 1997. The Company reinstated its bonus programs effective for fiscal
1998. Accordingly, the Company recognized bonus expense of $7.6 million during
fiscal 1998 as compared to none during the same period in the prior year.
 
     The Company's net revenues increased 55.4% to $58.4 million during fiscal
1998 as compared to fiscal 1997. The increase in the Company's net revenues
reflects an increase in the volume of services delivered to new clients, as well
as the leveraging of the Company's existing client base. For fiscal 1998, $20.1
million of revenue was derived from services delivered to new clients and $38.3
million related to the completion of projects or the undertaking of additional
projects from the Company's client base of the previous fiscal year. The Company
served 65 clients during fiscal 1998 as compared to 45 clients served during
fiscal 1997.
 
     Project personnel and related expenses increased $9.8 million, or 44.6%, to
$31.6 million during fiscal 1998 as compared to fiscal 1997. This increase
resulted from an increase in the number of client-serving professionals to
respond to growth, combined with the impact of the reinstatement of the bonus
program during the current year. The Company increased its client-serving
professional staff from 146 at March 31, 1997 to 175 at March 31, 1998. As a
percentage of net revenues, project personnel and related expenses decreased
from 58.2% to 54.2% during fiscal 1998, reflecting the improvement in
utilization of client-serving professionals.
 
     Professional development and recruiting expenses decreased $117,000 during
fiscal 1998 as compared to fiscal 1997. This decrease reflects the initial
investment in certain intellectual capital programs during fiscal 1997,
partially offset by the Company's training of a higher number of client-serving
professionals during fiscal 1998. The Company has continued its recruiting and
training programs to support the growth of the business. As a percentage of net
revenues, professional development and recruiting expenses decreased from 16.7%
to
 
                                       17
<PAGE>   18
 
10.6% during fiscal 1998 as a result of the Company's improved operating
leverage resulting from its net revenue growth.
 
     Marketing and sales expenses increased $1.3 million to $3.2 million during
fiscal 1998 as compared to fiscal 1997 as a result of the Company's investment
in its marketing and branding programs. The Company's marketing activities in
fiscal 1998 were focused on (i) the development of its magazine, "Context",
which was launched during the quarter ended December 31, 1997 and (ii) the
promotion of intellectual capital through the Diamond Exchange, the Company's
executive learning forum for senior executives. As a percentage of net revenues,
marketing and sales expenses increased from 5.1% to 5.5%.
 
     Management and administrative support expenses increased from $6.3 million
to $8.6 million, or 35.5%, during fiscal 1998 as compared to fiscal 1997. This
increase resulted from the cost of additional facilities, equipment and
personnel necessary to support the Company's growth and increased consulting
capacity, combined with the impact of the reinstatement of bonus programs. As a
percentage of net revenues, management and administrative support expenses
decreased from 16.9% to 14.7% as a result of the Company's improved operating
leverage resulting from its net revenue growth.
 
FISCAL 1997 COMPARED TO FISCAL 1996
 
     The Company's net income decreased $603,000 during fiscal 1997
fundamentally because of a net loss incurred during the six months ended
September 30, 1996 totaling $1.1 million. This net loss was more than offset by
net income of $1.7 million during the subsequent six months ended March 31,
1997. The Company's net income improvement during the last half of fiscal 1997
resulted from increased revenues combined with the impact of cost reductions
implemented during the year.
 
     The Company's net revenues continued to grow during each of the quarters in
fiscal 1997, despite the cancellation of two significant projects during the
last quarter of fiscal 1996 and the first quarter of fiscal 1997. The
cancellation of these projects resulted from (i) one client's acquisition of an
existing business which eliminated its need for Diamond's continued services in
assisting the client in the establishment of a similar business and (ii) the
other client's cancellation of the business initiative for which the Company had
been retained. The revenues from these two clients represented approximately
$3.8 million in the quarter ended March 31, 1996 and, after such cancellations,
represented approximately $1.5 million in the quarter ended June 30, 1996,
$300,000 in the quarter ended September 30, 1996 and zero in the quarter ended
December 31, 1996. At the time of these project cancellations, the Company was
in the process of increasing the number of its client-serving professionals to
support anticipated revenue growth. Accordingly, the lost revenue associated
with these projects, together with the expanded capacity for future anticipated
revenue growth, resulted in a higher than expected percentage of unassigned
professionals during each of the quarters ended June 30, 1996 and September 30,
1996 and net losses in these quarters of $714,000 and $385,000, respectively.
 
     The Company responded to the impact of this lost revenue and reduced
utilization of client-serving professionals by evaluating its cost structure and
eliminating or deferring certain planned spending and terminating certain
non-client-serving professionals. At the same time, the Company elected to
retain existing client-serving professionals so that it could be in a position
to respond to anticipated future growth. Finally, the following compensation
reductions were implemented to help the Company recover from the situation: (i)
the Company eliminated employee bonuses for the year ended March 31, 1997; (ii)
the Partners agreed to a temporary 8.3% reduction in compensation for one year
commencing with the quarter ended December 31, 1996; and (iii) certain of the
Partners forgave deferred compensation totaling approximately $485,000 during
each of the quarters ended December 31, 1996 and March 31, 1997, which were
recognized as reductions in operating expenses in the respective periods.
 
     The Company's net revenues increased 42.6% to $37.6 million in fiscal 1997.
The increase in the Company's net revenues reflects an increase in the volume of
services delivered to new clients, as well as the leveraging of the Company's
existing client base by undertaking additional projects for these clients. For
the year ended March 31, 1997, $18.3 million of revenue was derived from
services delivered to new clients and $19.3 million related to the completion of
projects or undertaking additional projects from the Company's
 
                                       18
<PAGE>   19
 
client base of the previous fiscal year. The Company served 45 clients during
fiscal 1997 as compared to 24 clients during fiscal 1996.
 
     Project personnel and related expenses increased $6.6 million to $21.9
million during fiscal 1997. In the aggregate, project personnel and related
expenses increased 42.8% from the prior year due to the increase in the number
of client-serving professionals hired during the period to respond to
anticipated future growth. The Company increased its client-serving professional
staff from 115 at March 31, 1996 to 146 at March 31, 1997. As a percentage of
net revenues, project personnel and related expenses increased slightly from
58.1% to 58.2% during fiscal 1997.
 
     Professional development and recruiting expenses increased from $4.6
million to $6.3 million, or 36.7%, during fiscal 1997 due to the increase in
recruiting and the training of a higher number of professional consultants. The
increase also reflects the Company's continued emphasis on its investment in
recruiting and training to support the growth of its business, partially offset
by certain cost containment initiatives undertaken in response to the previously
described project cancellations. As a percentage of net revenues, professional
development and recruiting expenses decreased to 16.7% as compared to 17.4%
during fiscal 1996.
 
     Marketing and sales expenses increased from $606,000 to $1.9 million during
fiscal 1997. As a percentage of net revenues, these expenses increased from 2.3%
to 5.1%, reflecting the Company's expanded investment in its marketing and sales
programs.
 
     Management and administrative support expenses increased from $4.5 million
to $6.3 million during fiscal 1997, or 42.3% as a result of the additional
facilities, equipment and personnel necessary to support the Company's growth
and increased consulting capacity. As a percentage of net revenues, management
and administrative support expenses decreased slightly from 17.0% to 16.9%.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company closed its initial public offering of common stock in April
1997 and received net proceeds totaling approximately $10.1 million. The Company
used $2.0 million of the proceeds from the initial public offering to repay a
loan from Safeguard Scientifics, Inc.
 
     Subsequent to fiscal 1998, the Company completed an offering of 3,000,000
shares of Class A Common Stock. In connection with this offering, the Company
sold approximately 650,000 shares of Class A Common Stock and the selling
shareholders sold approximately 2,350,000 shares of Class A Common Stock. Net
proceeds to the Company totaling approximately $16 million were realized in
April 1998.
 
     The Company also maintains a revolving line of credit pursuant to the terms
of a secured credit agreement from a commercial bank under which the Company may
borrow up to $3.0 million at an annual interest rate based on the prime rate or
based on the LIBOR plus 2.5%, at the Company's discretion. This line of credit
is secured by a lien on all of the property of the Company and the Company's
wholly owned subsidiary. This line of credit has been reduced to account for
letters of credit outstanding. As of March 31, 1998, the Company had
approximately $2.4 million available under this line of credit.
 
     The Company's billings for the quarter ended March 31, 1998 totaled $19.9
million. These amounts include billings to clients for out-of-pocket expenses
that are reimbursed by clients which are not included in recognized revenues.
The Company's gross accounts receivable balance of $5.6 million at March 31,
1998 represents 25 days of billings for the quarter.
 
     The Company believes that the net proceeds from the sale of the Class A
Common Stock in April 1998, together with its current cash balances and cash
flow from future operations, will be sufficient to fund its operating
requirements for at least fiscal 1999. Should the Company's business expand more
rapidly than expected, the Company believes that additional bank credit would be
available to fund such operating and capital requirements. In addition, the
Company could consider seeking additional public or private debt or equity
financing to fund future growth opportunities.

YEAR 2000 ISSUE
 
     Many existing computer programs were designed and developed without
considering the impact of the upcoming change in the century and consequently
use only two digits to identify a year in the date field. If not corrected, many
computer applications could fail or create erroneous results by or at the year
2000 (the "Year 2000 Issue"). The Company has reviewed the potential impact of
the Year 2000 Issue on its operations and has concluded that it will not be
material.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Diamond Technology Partners Incorporated:
 
     We have audited the accompanying consolidated balance sheets of Diamond
Technology Partners Incorporated and subsidiary as of March 31, 1997 and 1998,
and the related consolidated statements of operations, stockholders' equity and
cash flows for each of the years in the three-year period ended March 31, 1998.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Diamond
Technology Partners Incorporated and subsidiary as of March 31, 1997 and 1998,
and the results of their operations and their cash flows for each of the years
in the three-year period ended March 31, 1998 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) DESCRIPTION OF BUSINESS
 
     Diamond Technology Partners Incorporated (the "Company") is a management
consulting firm that synthesizes business strategy with information technology
to create innovative digital strategies for leading national and multi-national
corporations. The Company's clients are generally located throughout the United
States.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
the company and its wholly owned subsidiary. All intercompany accounts and
balances have been eliminated in consolidation. Certain prior period amounts
have been reclassified to conform with current period presentation.
 
  Revenue Recognition
 
     The Company recognizes revenues on contracts as work is performed, net of
provisions for estimated uncollectible amounts. Actual uncollectible amounts are
charged against this reserve when they become known. Out-of-pocket expenses are
reimbursed by clients and are offset against expenses incurred.
 
  Computers, Equipment and Training Software
 
     Computers, equipment and training software are stated at cost less
accumulated depreciation. Depreciation is based on the estimated useful lives of
the assets (generally three years) and is computed using the straight-line
method. Costs capitalized for internally developed software include external
consulting fees and employee salaries. Depreciation and amortization expense was
$317,000, $1,239,000 and $720,000 for the years ended March 31, 1996, 1997, and
1998, respectively.
 
  Organization Costs
 
     Organization costs consist of legal fees related to the start-up of the
Company. They are being amortized using the straight-line method over five
years. Accumulated amortization at March 31, 1996, 1997 and 1998 was $90,000,
$141,000 and $192,000, respectively.
 
  Cash and Cash Equivalents
 
     Cash equivalents are highly liquid investments with original maturities of
three months or less and are stated at cost, which approximates fair value. Cash
equivalents consist of money market funds and demand deposits.
 
  Significant Customers
 
     The Company had three customers which individually accounted for more than
10% of accounts receivable and revenues as of and for the year ended March 31,
1996. Collectively, these customers accounted for 56% of accounts receivable and
51% of revenues as of and for the year ended March 31, 1996. The Company had two
customers which individually accounted for more than 10% of accounts receivable
and one which accounted for more than 10% of revenues as of and for the year
ended March 31, 1997. Collectively, the two customers accounted for 38% of
accounts receivable and the one customer accounted for 14% of revenues as of and
for the year ended March 31, 1997. The Company had two customers which
individually accounted for more than 10% of accounts receivable and no customers
which individually accounted for more than 10% of revenues as of and for the
year ended March 31, 1998. Collectively, the two customers accounted for 31% of
accounts receivable.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Income Taxes
 
     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes," which
requires the use of the liability method of accounting for income taxes.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be reversed or settled.
 
  Earnings Per Share
 
     The Company's basic earnings per share and diluted earnings per share are
computed in accordance with Statement of Financial Accounting Standards No. 128
"Earnings Per Share," and are presented in accordance with Securities and
Exchange Commission Staff Accounting Bulletin ("SAB") No. 98. SAB No. 98 revised
the calculation of pre-initial public offering common stock and common stock
equivalent shares previously governed by SAB No. 83. The Company has
retroactively applied SAB No. 98 to all periods prior to fiscal year 1998.
 
     Basic earnings per share is computed using the weighted average number of
common shares outstanding. Diluted earnings per share is computed using the
weighted average number of common shares outstanding and the assumed exercise of
stock options and warrants (using the treasury stock method). Following is a
reconciliation of the shares (in thousands) used in computing basic and diluted
earnings per share for the fiscal years ended March 31, 1996, 1997 and 1998:

  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and

(6) STOCKHOLDERS' EQUITY
 
  Stock Split, Stock Recapitalization and Public Offerings
 
     The Board of Directors authorized a 1.65 to 1 stock split in the form of a
stock dividend effective February 18, 1997. All references in the financial
statements to share and per share data have been adjusted to effect this stock
split. Additionally, on February 18, 1997 the Company amended its certificate of
incorporation to divide its common stock into two classes, Class A and Class B,
and authorized 2,000,000 shares of Preferred Stock, par value $1.00 per share,
the terms of which may be determined by the Board of Directors. Class A Common
Stock is entitled to one vote per share and Class B Common Stock is entitled to
five votes per share on all matters submitted to the vote of holders of common
stock. Class B Common Stock may only be owned beneficially or of record by
employees of the Company or by the Company.
 
     On March 31, 1997, the Company completed its IPO and sold 1,755,000 of its
common shares at the price of $5.50 per share. The Company realized $8,476,000
in connection with the sale, net of the payment of the underwriters commissions
and other expenses of the offering. Of the net proceeds, $2,000,000 were used to
repay a loan from Safeguard. In the offering, an additional 1,600,000 shares
were sold by selling stockholders. On April 8, 1997, the underwriters, pursuant
to their exercise of the over-allotment option, purchased an additional 320,000
shares of the Company's common stock at $5.50 per share. The Company's proceeds
from these additional shares, net of expenses, were $1,595,000.
 
     Subsequent to the year ended March 31, 1998, the Company completed an
offering and sold 654,792 shares of Class A Common Stock at a price of $26.75
per share. The Company realized approximately $16,000,000 in April 1998 in
connection with the sale, net of payment of the underwriters' commissions and
other expenses of the offering. In the offering, an additional 2,345,208 shares
were sold by selling stockholders.
 
  Warrants and Stock Options
 
     In March 1994, the Company granted warrants to Safeguard. The warrants
allowed the holder to purchase up to 825,000 shares of stock at an exercise
price of $1.21 per share. Safeguard subsequently transferred 330,000 of these
warrants to certain of its affiliates. The Company had the right to require the
warrant holders to exercise the warrants at any time following the completion of
the Company's first full fiscal year of profitability. The Company satisfied
this requirement during the fiscal year ended March 31, 1996 and issued 825,000
shares of Class A Common Stock in exchange for $1,000,000 pursuant to the
provisions of the warrants.
 
     In November 1996, the Company granted additional warrants to Safeguard. The
warrants permit the holder to purchase up to 526,597 shares of stock at an
exercise price of $5.50 per share and expire on November 1, 2001. On January 31,
1997, Safeguard transferred 285,415 of these warrants to certain of its
affiliates.
 
     Under the Company's 1994 Stock Option Plan and under the Company's 1998
Equity Incentive Plan (collectively, the "Stock Option Plans" or "Plans"), the
Company may grant qualified incentive stock options to officers and employees of
the Company. The Stock Option Plans provide that, subsequent to the IPO, options
will be granted at the average of the closing price of a share of Class A Common
Stock on the Nasdaq Stock Market System for the ten trading days immediately
preceding the date of grant. Options have been granted to officers which vest
incrementally, with 10%, 15%, 25%, 25% and 25% of the option vesting on the
first through fifth anniversaries of the date of grant, respectively, and expire
on the seventh anniversary of the date of grant. Options have been granted to
employees which fully vest upon the third anniversary of the date of grant and
expire on the fifth anniversary of the date of grant. Options were separately
granted to employees on November 1, 1996 and February 10, 1997 which vested on
August 25, 1997 and expire on the fifth

March 11, 1998, which vest 18 months from the date of grant and expire on the
fifth anniversary of the date of grant. The Company's Board of Directors has
also granted non-qualified stock options to certain persons who were not
employees on the date of grant and certain non-employee members of the Board of
Directors. These non-qualified stock options vest over periods ranging from
immediate to five years.

(8) BENEFIT PLANS
 
  Deferred Compensation
 
     Certain officers of the Company previously agreed to defer a portion of
their annual compensation under a deferred compensation program. The program
provided that amounts deferred could not be distributed prior to March 31, 1996
without approval by the Board of Directors. Amounts deferred under this program
accrued interest at rates available to the Company from its bank and were
immediately vested. Effective April 1, 1996, the Board of Directors elected to
discontinue this program. Pursuant to an agreement entered into by all officers
who had deferred compensation, approximately $967,000 was forgiven during the
year ended March 31, 1997.
 
  401(k) Plan
 
     The Company has a noncontributory defined contribution plan covering
substantially all of its employees. This plan is qualified under Section 401(k)
of the Internal Revenue Code of 1986. The Company may elect to make
contributions to this plan but to date has not done so.

EXHIBIT 99.1

                                  RISK FACTORS


In evaluating the Company and its business, prospective investors should
consider carefully the following risk factors in addition to the other
information contained herein. This Annual Report on 10-K contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results may differ materially from the results discussed in the
forward-looking statements. Factors that might cause such a difference include,
but are not limited to, those discussed in the following risk factors.

CONCENTRATION OF REVENUES

      The Company has in the past derived, and may in the future derive, a
significant portion of its revenues from a relatively limited number of major
clients. During fiscal 1997, the Company had one client which individually
accounted for 14% of its net revenues. During fiscal 1998 the Company had one
client that individually accounted for 9% of its net revenues. From quarter to
quarter, revenues from one or more individual clients may exceed 10% of the
Company's revenues for the quarter. In general, there are no long-term
commitments by any of the Company's clients for the Company's services and many
of the Company's engagements are, and may be in the future, terminable without
penalty. During the last quarter of fiscal 1996 and the first quarter of fiscal
1997, the Company's then two largest clients terminated projects with the
Company, contributing to a net loss for the first six months of fiscal 1997 of
approximately $1.1 million. There can be no assurance that the Company's major
clients will continue their relationships with the Company and be a significant
source of revenue for the Company or that they will not terminate major projects
at any given time. Any unanticipated termination of a major project or the loss
of any one of the Company's large clients will have a material adverse effect on
the Company's business, financial condition and results of operations.

VARIABILITY OF QUARTERLY OPERATING RESULTS

      The Company has experienced and may in the future continue to experience
fluctuations in its quarterly operating results. Factors that may cause the
Company's quarterly operating results to vary include the number of active
client projects, the requirements of client projects, the termination of major
client projects, the loss of major clients, the timing of new client engagements
and the timing of personnel cost increases. Certain of these factors may also
affect the Company's personnel utilization rates which may cause further
variation in quarterly operating results. The timing of revenues is difficult to
forecast because the Company's sales cycle is relatively long and the Company's
services are impacted by both the financial condition and management decisions
of its clients and general economic conditions. Because a high percentage of the
Company's expenses are relatively fixed at the beginning of any period and the
Company's general policy is to not adjust its staffing levels based upon what it
views as short-term circumstances, a variation in the timing, initiation or
completion of client assignments, particularly at or near the end of any
quarter, can cause significant variations in operating results from quarter to
quarter and could result in losses for any particular period. In addition, many
of the Company's engagements are, and may be in the future, terminable by its
clients without penalty. A termination of a major project could require the
Company to maintain under-utilized employees, resulting in a higher than
expected percentage of unassigned professionals, or to terminate the employment
of excess personnel. Due to all of the foregoing factors, there can be no
assurance that the Company's results of operations will not be below the
expectations of investors for any given fiscal period.

RECENT OPERATING LOSSES AND LIMITED OPERATING HISTORY

      The Company has been in existence since January 28, 1994. In fiscal 1994
and fiscal 1995, the Company experienced losses due primarily to the
developmental nature of the business. While the Company was profitable in fiscal
1996, 1997 and 1998, the Company experienced the cancellation of significant
projects at its then two largest clients in the last quarter of fiscal 1996 and
the first quarter of fiscal 1997. The cancellation of these projects resulted
from each client's cancellation of the business initiative for which the Company
had been retained. As a result of the cancellation of these two projects and the
increase in the Company's operating expenses caused by the Company's expansion,
the Company experienced a net loss of approximately $1.1 million during the
first six months of fiscal 1997. In addition, to support the growth of its
business, the Company expanded its level of operations and increased operating
expenses in all areas during fiscal 1996, fiscal 1997 and fiscal 1998. The
Company's business, financial condition and results of operations will be
adversely affected in any period if revenues do not increase sufficiently to
cover the Company's expanded level of operations and increased operating
expenses. There can be no assurance that the Company will be successful in its
efforts to so increase its revenues.

CONTROL BY CHIEF EXECUTIVE OFFICER; ELECTION OF FUTURE CHIEF EXECUTIVE OFFICERS

      All employee-stockholders of the Company have granted a proxy to vote
their shares of Class B Common Stock to the person holding the position of Chief
Executive Officer of the Company. Accordingly, as of April 30, 1998, the
Company's current Chief Executive Officer controls (including Class A Common
Stock owned by such individual) 


<PAGE>   2

approximately 69.8% of the voting rights of the outstanding Common Stock of the
Company and will have the voting power to elect the Company's entire Board of
Directors and to approve all matters requiring stockholder approval. In
addition, an agreement among the Company and the Partners requires that the
Company's Chief Executive Officer be selected from the Partners. This
significantly limits the number of qualified persons that may be considered for
such office. Accordingly, there can be no assurance that the Company will be
successful in attracting future persons who are qualified to serve as the
Company's Chief Executive Officer and the inability to attract such persons
could have a material adverse effect on the Company's business, financial
condition and results of operations.

RELIANCE ON KEY PERSONNEL; RECRUITMENT AND RETENTION OF PROFESSIONALS

      The Company's success depends upon the continued service of its key
executive officers and its ability to attract, retain and motivate highly
skilled professionals at all levels. Qualified client-serving professionals are
in particularly great demand and are likely to remain a limited resource for the
foreseeable future. The loss for any reason of a key executive officer or a
number of the Company's client-serving professionals or the inability to attract
qualified personnel could have a material adverse effect on the Company's
business, financial condition and results of operations.

ABSENCE OF LONG-TERM CONTRACTS

      The Company's clients are generally able to reduce or cancel their use of
the Company's professional services without penalty and with little or no
notice. As a result, the Company believes that the number of clients or the
number and size of its existing projects are not reliable indicators or measures
of future revenue. The Company has in the past provided, and is likely in the
future to provide, services to clients without a long-term agreement. When a
client defers, modifies or cancels a project, the Company must be able to
rapidly deploy its professionals to other projects in order to minimize the
underutilization of employees and the resulting adverse impact on operating
results. In addition, the Company's operating expenses are relatively fixed and
cannot be reduced on short notice to compensate for unanticipated variations in
the number or size of projects in progress. As a result, any termination,
significant reduction or modification of its business relationships with any of
its significant clients or with a number of smaller clients could have a
material adverse effect on the Company's business, financial condition and
results of operations.


MANAGEMENT OF GROWTH

      The Company has been experiencing a period of substantial growth that has
placed, and is anticipated to continue to place, a strain on the Company's
financial and other resources. During fiscal 1997 and fiscal 1998, the size of
the Company's employee base increased from 145 to 223 full-time employees.
Further increases are anticipated in the future. The Company's ability to manage
the growth of its professional staff will require it to continue to improve its
operational, financial and other internal systems, and to train, motivate and
manage its employees. If the Company's management is unable to manage growth
effectively and new employees are unable to achieve anticipated performance
levels, the Company's business, financial condition and results of operations
could be adversely affected.

PROJECT RISKS

      Because many of the Company's projects are critical to its clients, a
failure or inability of the Company or one of its subcontractors to meet a
client's expectations could damage the Company's reputation and adversely affect
its ability to attract new business. Although the Company generally attempts to
limit its liability by contractual terms, the failure of a significant project
could lead to claims by a client for economic damages. In addition, the failure
of a project or the failure of the Company to collect a large account receivable
could also result in significant financial exposure to the Company, which could
have a material adverse effect on the Company's business, financial condition
and results of operations. From inception through March 31, 1998, the Company
has written off accounts receivable totaling approximately $1.5 million which it
could not collect.

TECHNOLOGICAL ADVANCES

      The Company's success will depend in part on its ability to develop
strategic business and IT solutions which keep pace with continuing changes in
industry standards, IT and client preferences. There can be no assurance that
the Company will be successful in addressing these developments on a timely
basis or that, if addressed, the Company will be successful in the marketplace.
The Company's delay in addressing or failure to address these developments could
have a material adverse effect on the Company's business, financial condition
and results of operations.

COMPETITION

      The management consulting and systems integration services markets include
a large number of participants, are subject to rapid changes and are highly
competitive. The Company competes with, and faces potential competition for
client assignments and experienced personnel from, a number of companies that
have significantly greater financial, technical and marketing resources, greater
name recognition, and greater revenues than the Company. The Company 

<PAGE>   3

believes that the principal competitive factors in the segment of the consulting
industry in which the Company competes include scope of services, service
delivery approach, technical and industry expertise, perceived value,
objectivity and results orientation. The Company believes that its ability to
compete also depends in part on a number of competitive factors outside of its
control, including the ability of its competitors to hire, retain and motivate
senior project managers, the price at which others offer comparable services,
and the extent of its competitors' responsiveness to customer needs. There can
be no assurance that the Company will be able to compete successfully with its
competitors in the future.

LIQUIDITY

      The Company was not profitable in the first two quarters of fiscal 1997.
While the Company has been profitable since the third quarter of fiscal 1997,
there can be no assurance that the Company will continue to be profitable in the
future. The Company believes that existing cash resources, the amounts available
under its revolving line of credit and cash generated from operations will be
sufficient to satisfy its operating cash needs for at least the next 12 months.
Any future decreases in its operating income, cash flow, or stockholders' equity
may impair the Company's future ability to raise additional funds to finance
operations. There can be no assurance that the Company will in the future
maintain adequate liquidity to support its operations.

POSSIBLE VOLATILITY OF STOCK PRICE

      The Class A Common Stock of the Company has been listed on the Nasdaq
National Market since February 1997. The market price of the Class A Common
Stock has experienced variations, ranging from a high of $30.00 to a low of
$5.75, and there can be no assurance that the market price of the Class A Common
Stock will not experience fluctuations in the future or will not fall below such
levels. The market price of the Class A Common Stock could be subject to wide
fluctuations in response to quarterly variations in operating results, changes
in earnings estimates by analysts, announcements of new contracts or service
offerings by the Company or its competitors, general economic or stock market
conditions unrelated to the Company's operating performance or other events or
factors.
