Item 1. Business.


 GENERAL

           Giga Information Group, Inc. ("Giga") provides objective research,
advice and continuous coaching on technology for e-Business. Giga's integrated
suite of offerings helps clients make strategic decisions about the
technologies, people and processes needed to excel in the new digital economy.
Emphasizing close interaction among analysts and clients, Giga delivers support
with the speed and scope necessary for e-Business.

           Giga began providing continuous information services ("CIS" or
"Continuous Information Services") in April 1996. As of December 31, 1999, Giga
had a global client base encompassing more than 1,100 organizations and over
125,000 licensed users. Its enterprise clients include companies that use, sell
and invest in technology.

            The majority of Giga's Continuous Information Services are available
to customers for an annual subscription fee billed and payable in advance.
"Advisory Service(R)", the principal service offering of Giga, entitles members
to (i) access all Giga's advisory service information and analyses, (ii) inquiry
privileges and (iii) participate in briefings, a conference and teleconferences.

           Giga has designed its products and services to capitalize on the
capabilities of the Internet. Giga believes it became the first Internet-centric
advisory firm by creating GigaWeb(R), a unique content portal that enables
access to the full spectrum of Giga's original research, selected third party
content and human expertise. Giga's newly released GigaWeb version 3.0 also
enables clients to engage in virtual topic-oriented communities hosted and
moderated by Giga analysts. In addition, Giga maintains a knowledge management
environment designed for electronic delivery and collaboration among analysts
and clients, facilitated through the Internet.

           Giga was organized on March 17, 1995. In April 1995, Giga acquired
BIS Strategic Decisions, Inc. ("BIS") as part of its strategic plan to
accelerate the development of its CIS business and to obtain the marketing,
sales and other corporate infrastructures and certain personnel of BIS. In July
1995, Giga acquired a majority equity interest in ExperNet Corporation
("ExperNet(R)"), which was owned by Gideon I. Gartner and David L. Gilmour, each
currently a director and an officer of Giga at that time. In December 1995, Giga
acquired the remaining equity interest in ExperNet.

           In June 1996, Giga discontinued the BIS market research business. In
connection with its Advisory Service, Giga continues to generate revenues from
the events and conferences businesses acquired as part of the acquisition of
BIS. These revenues are reflected in the statements of operations as Other
Services. In December 1996, Giga discontinued its econometric forecasting
business, BIS Shrapnel, and in July 1997, this operation was sold to local
management.

           Giga launched its sales of Advisory Services in April 1996 and
continued to grow and invest and expand its services, reaching in excess of the
750-client mark at December 31, 1997, in excess of the 950-client mark at
December 31, 1998, and in excess of the 1,100-client mark at December 31, 1999.
The Company launched its initial public offering of common stock ("the
Offering") on July 31, 1998. In May 1999, Robert K. Weiler was named to succeed
founder Gideon I. Gartner as president and chief executive officer, and assumed
full-time duties in August 1999. Mr. Weiler assumed the position of chairman in
the fourth quarter of 1999. Mr. Gartner remains a member of Giga's board of
directors.

MARKET FOCUS AND THE GIGA SOLUTION

           Giga focuses on the IT Research Segment of the Syndicated Research
Market. "IT", or the Information Technology, industries are primarily those
concerned with computing, telecommunications and other related industries.
Typically, Syndicated Research companies develop a product which is sold to
multiple clients. In general, these products include primary and secondary
research and analyst support as part of the offering. Within IT, Giga targets
its offerings on issues relating to technology for e-Business.

           Giga views e-Business as more than just a company having an
electronic link in a supply chain or a Web site on the Internet. Giga approaches
e-Business with clients as a source of strategic advantage -- one which
incorporates all of the new technologies, processes and practices leading to an
interconnected organization and one that is designed to allow one company to
completely outdistance another.

           Giga realized that an advisory model based on e-Business was crucial
in a market that demands the kind of technology integration made possible by the
Internet. Accordingly, Giga developed an integrated advisory offering that could
be delivered and supported via the Web and that helps clients make informed
decisions about e-Business technologies and strategies through rapid access to
comprehensive and experience-based analysis and advice.

           Giga's integrated Advisory Service, in which IT research and analysis
is offered to customers as a single service, is intended to encompass the
variety of e-Business coverage offered by other providers through multiple and
fragmented services. Giga believes that its Advisory Service (i) delivers the
comprehensive viewpoint required by customers, (ii) offers a price/performance
advantage since the payment of one subscription fee provides access to all
advisory research and (iii) becomes increasingly cost effective over time as new
advisory research is added without increased subscription fees.

           Giga developed its approach in response to the needs of the market.
Giga's integrated Advisory Service produces internal benefits which Giga
believes allows it to better service its customers, including (i) flexibility of
resource allocation, (ii) an orientation toward internal collaboration and (iii)
the development of experienced generalists, who are able to diagnose broad
client e-Business challenges and communicate effectively with clients.
Flexibility of resource allocation allows Giga to focus its research resources
to address subjects of the greatest significance to its customers at any
particular time. Giga's orientation toward internal collaboration eliminates the
competition among different advisory areas that Giga believes is customary at
other providers. Instead, Giga encourages its analysts to work together in a
multi-disciplinary approach and present a unified view to its customers. The
process is also designed to be objective, by virtue of several features built
into Giga's methodologies, such as a requirement that analysts articulate
balanced opinions that include probabilities of occurrence and alternative
viewpoints. In addition, research is available to clients on a timely basis
through GigaWeb's sophisticated authoring technology. The customization features
permitted by GigaWeb also make Giga's research more relevant to specific client
environments.

           Giga's "Advisory Consulting" services provide Giga customers with
support via a retainer-based consulting arrangement to assess various IT issues,
including an organization's strategic technology plan, a vendor's marketing
plan, or the implementation issues surrounding a major technology migration.
Advisory Consulting is a valuable extension of Giga's client inquiry process,
enabling customers to request more in-depth analysis targeted at the application
of technology to their specific situation.

           Giga also offers customers its innovative "ePractices(TM)" service to
complement its Advisory Service. Giga's ePractices advisors continually
identify, track and analyze the innovative e-Business practices that are
designed to help top companies capture new customers, enter new markets and
create new opportunities - faster and more effectively than their competitors.
This research is distilled into a "living" electronic library of successful
practices. To maximize the value of this ongoing research, Giga's senior
advisors apply their own expert perspective to Giga's cumulative knowledge base
to help define and drive the strategies, organizational changes and business
processes needed for enhanced e-Business success.


                                       3
<PAGE>


           Giga's innovative Web Site ScoreCard(TM) service is a comprehensive
evaluation of an organization's Web site to help it better compete online. This
service provides an in-depth assessment with recommendations on how to
strengthen an organization's e-commerce and online initiatives. ScoreCard
results and recommendations are not made public by Giga, but are designed as
strategic internal documents to help an organization improve its Web site in
order to gain competitive advantage

           GigaWeb 3.0, Giga's interactive Web destination for e-Business
research and discussion, allows customers to easily and efficiently navigate
through the full spectrum of original research which is organized into
"Knowledge Salons(TM)." Knowledge Salons are continuously updated virtual
communities, in which research, analysis and points of view are shared and
debated via the Web. Each Knowledge Salon centers on an e-Business issue driven
by a catalyst, such as a client inquiry, industry event or discussion among Giga
analysts and advisors. A Giga senior analyst hosts each Knowledge Salon, and is
responsible for keeping the content - including the growing body of Giga's
e-Business research - fresh and up-to-date. In keeping with Giga's collaborative
approach to research, Knowledge Salons will include a broad range of documents
on topics critical to a full understanding of e-Business issues and technology
interrelationships.

           Through the use of intelligent software agents on GigaWeb, Giga is
able to provide customized information to each customer and to allow customers
to search for and select the information that is most relevant to their
particular needs. GigaWeb also enables collaboration with Giga's clients and
maintains rich features, which improve the usability of Giga research. In
addition, to complement Giga's research and inquiry access, Advisory Service
customers are provided access to ExperNet, Giga's network of external IT
practitioners who have practical experience in solving real-world IT problems.


GIGA STRATEGY

           Giga's objective is to become a leading provider of e-Business
advisory and consulting services, offering a significant price/performance
advantage over its competitors. The key elements of Giga's strategy include:

           o          Offering e-Business advisory and consulting service models
                      based on e-Business needs. Giga has developed research and
                      fulfillment models based on the premise that companies
                      need issues-based integrated research, advisory and
                      coaching services to succeed in the digital economy. Giga
                      recognizes that business strategies and multiple
                      technologies are closely tied together and therefore
                      cannot be separated by arbitrary service divisions that
                      force clients to subscribe to multiple services in order
                      to gain the information/advice needed to make decisions.

           o          Utilizing and Enhancing its Price/Performance Advantage.
                      Giga intends to use its price/performance advantage to
                      increase the range of companies which can afford its
                      services and to allow customers to offer Giga's content to
                      a wider group of employees than has been affordable with
                      competitors' products.

           o          Leveraging Existing Customer Base. Giga's services are
                      used by over 1,100 client organizations worldwide. Giga
                      intends to expand its Advisory customer relationships by
                      providing additional services, such as ePractices
                      services, Web Site ScoreCard and Advisory Consulting. In
                      addition, Giga is focused on increasing the number of
                      Advisory Service subscribers within each customer's
                      organization.

           o          Using new products and services to create growth
                      opportunities. New products, such as the Web Site
                      ScoreCard and ePractices services, enable Giga to attract
                      and retain customers that may not be considering Advisory
                      Services. Using new services, Giga can create additional
                      relationships that provide an opportunity to sell
                      additional services.

           o          Creating new distribution channels for research content.
                      Giga is exploring distribution partnerships to increase
                      visibility for Giga's e-Business expertise and to generate
                      revenue.

           o          Capitalizing on Worldwide Distribution.. Giga has entered
                      into agreements with distributors located in the
                      Asia/Pacific region, Europe and South America, and intends
                      to develop additional international distribution
                      arrangements.


PRODUCTS AND SERVICES

           Giga's four principal products and services are (i) Advisory Service,
which includes ExperNet and Advisory Consulting, (ii) ePractices (formerly IT
Practice Services), (iii) Events and Conferences, and (iv) Web Site ScoreCard.
Giga's services are designed to be accessed through GigaWeb, partner Web sites
and consultation with the Company's analysts and advisors.

           Giga's principal CIS products, Advisory Service and ePractices
services, are typically sold as annual contracts that renew automatically unless
the customer cancels the subscription. Giga's experience has been that
substantial portions of customers renew expiring contracts for an equal or
greater level of total fees each year. (see "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Overview.") Giga
prices its services in a manner designed to be competitive in the marketplace. A
typical Advisory Service contract currently has an Annualized Value of
approximately $50,000 and a typical ePractices service contract currently has an
Annualized Value of approximately $41,000. Giga defines Annualized Value ("AV")
as the cumulative annualized subscription value of Giga's continuous information
service agreements in effect at a given point in time. Giga's events and
conferences are typically attended, by Giga clients and non-clients, for a
nominal registration fee. Giga's Web Site ScoreCard is sold on a project basis,
with initial analysis and recommendations followed up by a second review after
six months. The average Web Site ScoreCard contract is approximately $46,000.

Advisory Service

            Giga Advisory is a unique, single-service plan that eliminates the
client's frustration of having to choose among numerous IT advisory services
within the same organization. It examines specific technologies, products and
solutions in the context of their implications and impact on other technologies
and on the business. The results are strategic and tactical analysis,
perspectives and recommendations.

           Within this unified service, Giga covers a broad range of
competencies, grouped into seven core disciplines:

           o          Application Development
           o          Communications & Networking
           o          Computing Infrastructures
           o          e-Business Applications & Strategies
           o          Information & Knowledge Management
           o          IT Management & Services
           o          Personal & PC Server Platforms & Security

           Giga's flexible, integrated approach provides clients with strategic
and practical e-Business recommendations at what Giga believes to be a superior
price/performance ratio. By offering unlimited access to virtually all Giga
content and Giga analysts, as well as immediate access to ExperNet, a Giga
Advisory membership can help a client's management team make better-informed
business and technical decisions.

           Giga's Research Process
           -----------------------

           To effectively meet client needs for Continuous Information Services
on technology and e-Business, Giga's research is driven by catalysts such as
client inquiries, external events and trends, as well as analyst insight, and
remains focused on the economic, technical and managerial forces shaping the
evolution of e-Business. This research, the objectivity of which is supported
through a published Objectivity Statement unique to Giga, is used by Giga
analysts to provide clients with both strategic and tactical analysis and
recommendations. The result is information that is practical rather than a
collection of analytical "sound bites."

           Giga analysts provide action-oriented recommendations that focus on
the here and now, not just longer-term strategic views. Giga's collaborative
research process allows Giga analysts to advise on the cause and effect of those
recommendations, thus allowing more effective decision-making by its clients.

           As of December 31, 1999, Giga employed approximately 79 research
professionals and plans to hire additional research staff, as needed. Giga's
principal research offices are located in Cambridge, Massachusetts, Norwalk,
Connecticut and Santa Clara, California. Giga's analysts average 17 years of
experience with backgrounds ranging from consulting to vendor and user
professional positions.

           ExperNet
           --------

           To complement its staff of full-time strategic analysts, Giga offers
ExperNet, the IT research industry's first "expert advice desk." ExperNet is an
exclusive worldwide network of more than 1,000 selected and highly qualified IT
practitioners and consultants who provide Giga clients with hands-on advice
spanning vertical and geographic markets on virtually all topics relevant to IT
and e-Business.

           Advisory Consulting
           -------------------

           Giga's Advisory Consulting service offers customized consulting
relationships with Giga analysts who develop a thorough understanding of a
client's IT environment while providing in-depth e-Business counsel. Advisory
Consulting complements the full range of Giga's advisory offerings by fulfilling
a client's need for detailed custom analysis and advice.

ePractices

           Giga's ePractices offering represents a new method of working with
clients and is unique among research, advisory and consulting firms. The
ePractices service provides market-tested insight designed to help organizations
make the most of opportunities offered by e-Business. Clients can leverage the
experience and knowledge of Giga's advisors, who are seasoned IT practitioners,
with the successful and innovative e-Business techniques of leading companies
worldwide.

            Giga's ePractices knowledge base is delivered to clients via GigaWeb
as well as through on-site consultations with Giga advisors. Research and
consulting are conducted in the following areas:

           o          Development of an e-Business "vision" & process
                      architecture
           o          Organizational plan to fulfill the e-Business strategy
           o          Plan for building e-Business applications
           o          Security and infrastructure plan to support e-Business
                      initiatives

Web Site ScoreCard

           Giga launched its innovative Web Site ScoreCard service in the third
quarter of 1999. Web Site ScoreCard is designed to help a client objectively
evaluate its Web site strategy and tactics for pursuing electronic commerce by
benchmarking its current site against competitor sites and other "best of breed"
sites. Web Site ScoreCard clients work closely with senior Giga analysts on
customized projects that are designed to provide them with concrete metrics and
solid, non-biased recommendations for use by the client's staff.

Events and Conferences

           Giga Information Group's e-Business events and conference series is
designed to inform and inspire today's IT and business executives as they drive
their organizations forward in the e-Business world. To successfully manage and
implement e-Business requires a holistic approach with technology at the center
of business strategy - an approach reflected in Giga's unique collaborative
Advisory offering and one that forms the foundation of its events.

           The e-Business conference series focuses on the specific strategy,
management and technology challenges of operating an e-Business in the global
digital economy, and covers applications, infrastructures, connectivity and
mobility, customer management, IT and business alignment, emerging technologies
and organizational issues.

           Giga's flagship annual conference is Giga World IT Forum, which
provides unique opportunities for Giga clients and other attendees to interact
closely with Giga analysts, advisors and guest faculty.

Publications

           Since its inception, Giga has produced and marketed a series of
off-the-shelf publications based on conference topics or IT issues identified
through its Advisory Service. Beginning in 1996 and continuing throughout 1999,
Giga has consistently reduced the resources and focus devoted to these
publications. This product no longer constitutes a material or significant
portion of Giga's revenues.

GigaWeb and Other Delivery Mechanisms

            GigaWeb is an award-winning Web site that provides Giga clients with
an interactive online destination for immediate access to original research and
analysis as well as external IT and business news. A customized virtual office
provides an intuitive layout, powerful agent-assisted search engine, and daily
notifications of new content through personalized saved searches called
GigaBots(R). Giga believes GigaWeb is the industry's most direct and
comprehensive channel to IT and e-Business information.

           IntraGiga(TM) is ideal for companies that want rapid and secure
access to Giga's research content without being connected to the Internet. By
residing on an organization's server, IntraGiga enables the customization of
Giga knowledge within an organization and control of the flow of information.

           Giga also supports clients with its Knowledge Center, which is
staffed by associates who track customer inquiries, direct clients to the
appropriate analyst or information source, and assist customers with other
research-related concerns. To protect client timetables, the Knowledge Center
handles client inquiries with an inquiry response support methodology that is
unique in the IT research industry.

           Giga's Client Care Services is an added benefit that clients receive
with their Advisory Services. Client Care associates are dedicated to assisting
clients with training and satisfaction issues. They also engage clients through
proactive outbound calls - enhancing their use of existing services, increasing
the value of their memberships and improving their overall satisfaction.

           Giga also offers select clients a complimentary Field Analyst who is
dedicated to facilitating their interaction with Giga's analyst community. The
Field Analyst serves as the client's day-to-day proactive connection to Giga,
providing improved access to Giga resources.

           Giga also conducts quarterly reviews of all client accounts to help
clients maximize their return on their research investment. This program also
provides Giga with valuable feedback that helps it continuously improve Giga
services.

SALES AND MARKETING

           Since inception, Giga has made substantial investments in sales and
marketing to sell its services, address additional markets and support its
growing customer base. Giga sells its services through a direct sales force
located in the United States, Canada, United Kingdom, France, Germany, the
Netherlands, Denmark, and Sweden. As of December 31, 1999, Giga's North American
field sales representatives numbered 66, a decrease from 100 field sales
representatives at December 31, 1998 and 87 representatives at December 31,
1997. Giga also had 21 field sales representatives serving Europe, a decrease
from 29 field sales representatives at December 31, 1998 and an increase from 19
representatives at December 31, 1997. All Giga sales representatives participate
in Giga's annual sales compensation plan. Commissions are paid monthly based
upon attainment of quotas versus established quotas. Additional bonuses and
other incentives are paid for meeting and/or exceeding certain established
targets and for special promotions. Giga's internal marketing organization,
primarily located in Giga's Cambridge, Massachusetts and Norwell, Massachusetts
facilities, provides public relations, lead generation, direct mail support and
other related services.

           Giga also sells its services through independent representatives in
Italy, Israel, Korea, Argentina and Brazil. These representatives are
compensated based on the contract value of the contracts generated by them. The
representatives are involved in other activities related to IT technology,
mainly consulting, but they do not represent any products or perform any
services that conflict with Giga's services. To date, revenues from these
representatives have been insignificant

           Giga has over 1,100 enterprises as clients. No single customer
accounted for over 10% of Giga's revenues for the years ended December 31, 1999,
1998 and
1997.


COMPETITION

           Giga competes in the IT market directly with other independent
providers of Continuous Information Services, including Gartner Group, META
Group, Inc. and Forrester Research Inc., and the internal planning, research and
marketing staffs of corporations and IT vendors. Giga also competes with other
information providers, including market research firms, "Big Five" accounting
firms, consulting firms and systems integrators. Many of Giga's direct and
indirect competitors have substantially greater financial, information gathering
and marketing resources than Giga. Some of Giga's direct and indirect
competitors also have established research organizations with greater market
recognition and experience in the IT industry.


EMPLOYEES

           As of December 31, 1999, Giga employed 387 persons, including 139 in
research and research support, 24 in events and conferences and publications,
145 in sales and marketing, 14 in research and development and 65 in
administration. Of such employees, 101 are located in Giga's Norwell facility,
71 are located in Giga's Cambridge headquarters, 90 are located in Giga's other
domestic facilities, 70 are located internationally and 55 work from their
homes. None of Giga's employees are represented by a collective bargaining
arrangement and Giga believes its relationship with its employees is good.

Item 2. Properties.

           Giga's headquarters are located in Cambridge, Massachusetts and
consist of approximately 15,500 square feet. This facility and approximately
27,000 square feet in its Norwell, Massachusetts facility together accommodate
corporate administration, research, analysis and advisory, marketing and sales
and customer support. The lease on the Cambridge facility expires in July 2004
and the lease on the Norwell facility expires in June 2001. The Company also
leases office space for its research, and sales and marketing efforts in seven
other U.S. and three primary international locations. The Company believes that
additional facilities will be available in the future on commercially reasonable
terms to meet future needs.

Item 3. Legal Proceedings.

           Giga Media BV, the owner of a Benelux trademark registration for the
trademark GIGA MEDIA, filed a lawsuit (docket number 81567 AL/98-509HH) on March
12, 1998 against the Company alleging tradename infringement, and requesting a
court order requiring the Company to use an alternative tradename to Giga
Information Group in the Netherlands. The matter is pending before the Cantonal
Judge at Haarlem, the Netherlands. Although the Company is contesting this
lawsuit, there can be no assurance that it will result in a decision that is
favorable to the Company.

           In addition to the proceeding described above, the Company from time
to time is involved in certain other litigation arising in the normal course of
its business. The Company does not believe that any such litigation, alone or in
the aggregate, would have a material adverse effect on the Company's financial
condition or results of operations.


Item 4. Submission of Matters to a Vote of Security Holders.

           None.

ORGANIZATION OF THE COMPANY AND FINANCIAL STATEMENT PRESENTATION

           Giga was organized on March 17, 1995. In April 1995, Giga acquired
BIS as part of its strategic plan to accelerate the development of its CIS
business and to obtain the marketing, sales and other corporate infrastructures
and certain personnel of BIS. In July 1995, Giga acquired a majority equity
interest in ExperNet, which was owned by Gideon I. Gartner and David L. Gilmour,
each currently a director and an officer of Giga at that time. In December 1995
Giga acquired the remaining equity interest in ExperNet.

           This Annual Report on Form 10-K includes selected consolidated
financial data (refer to Item 6. Selected Consolidated Financial Data) for BIS,
as the predecessor to Giga Information Group, Inc. for the period January 1,
1995 through April 5, 1995, the date of its acquisition by Giga. The periods
covered by the financial statements of Giga Information Group, Inc. commence on
March 17, 1995, the date of its incorporation, and include the results of
operations of BIS from April 5, 1995, the date of its acquisition, and the
results of operations of ExperNet from July 6, 1995, the date of its
acquisition. Results of operations of ExperNet are not included in results of
Predecessor Companies, which are solely the results of BIS. The acquisition of
BIS was accounted for under the purchase method; accordingly, acquired assets
were recorded at their estimated fair values and related goodwill of
approximately $3.1 million was also recorded and was amortized over two years.
The acquisition of ExperNet was also accounted for as a purchase with the
related goodwill of approximately $1.4 million amortized over five years. During
1997, the unamortized portion of the goodwill relating to the ExperNet
acquisition was written off, resulting in a charge to amortization expense of
$1.0 million.

           In June 1996, Giga discontinued the BIS market research business.
Giga continues to generate revenues from the events and conferences businesses
acquired as part of the acquisition of BIS, which are reflected in the
statements of operations as Other Services. As a result of discontinuing the BIS
market research business, Giga recorded a charge, net of taxes, of approximately
$2.3 million in the year ended December 31, 1996. Giga entered into agreements
with two unrelated parties, which have assumed responsibility for fulfillment of


                                       15
<PAGE>

Giga's obligations to former BIS customers in exchange for a share of the
deferred revenues recorded by Giga with respect to such customers. In 1997, Giga
recorded a gain of approximately $1.1 million comprised mainly of a reversal of
the provision for future lease commitments and related expenses for two
facilities in England and the provision established for refunds to potentially
dissatisfied customers. Giga does not consider the historical results of BIS
operations, which have been discontinued, to be meaningful or indicative of its
future results of operations.

           In December 1996, Giga, in anticipation of a sale to local
management, discontinued its econometric forecasting business, BIS Shrapnel,
which was based in Australia. Giga recorded a provision of $160,000 in 1996 for
anticipated operating losses prior to the completion of the sale. In July 1997,
the operations were sold to local management for approximately $293,000 in cash,
and a gain of approximately $212,000, net of taxes, was recorded and is
reflected in disposal of discontinued operations. All liabilities and business
risks were transferred to the local management of BIS Shrapnel.


OVERVIEW

           Giga provides objective research, advice and continuous coaching on
technology for e-Business. Giga's integrated suite of offerings helps clients
make strategic decisions about the technologies, people and processes needed to
excel in the new digital economy. Emphasizing close interaction among analysts
and clients, Giga delivers support with the speed and scope necessary for
e-Business. Giga's four principal product and services are (i) Advisory Service,
which includes ExperNet and Advisory Consulting, (ii) ePractices (formerly IT
Practice Services), (iii) Events and Conferences, and (iv) Web Site ScoreCard.
Giga's services are designed to be accessed through GigaWeb, partner Web sites
and consultation with the Company's analysts and advisors.

           Giga introduced its Advisory Service and GigaWeb in April 1996. In
July 1996, Giga introduced its ePractices services (formerly IT Practice
Services). Advisory Consulting was introduced in September 1997. Giga's Events
and Publications product line was acquired with the acquisition of BIS in April
1995. Giga's Web Site ScoreCard offering was launched in the third quarter of
1999. For financial reporting purposes, revenues from (i) Advisory Service,
ePractices services and Advisory Consulting are aggregated into Continuous
Information Services, (ii) Events and other services, principally consulting and
Web Site ScoreCard, are aggregated into Other Services and (iii) Publications
are listed separately. Giga expects that CIS revenues will continue to increase
as a percentage of its total revenues.

           Giga's principal CIS products, Advisory Service and ePractices
services, are typically sold through annual contracts that generally provide for
payment at the commencement of the contract period. A small number of these
contracts, however, are billed quarterly or monthly. Amounts received in advance
of services provided are reflected in Giga's financial statements as deferred
revenues and are recognized monthly on a prorata basis over the term of the
contract. Revenues from Other Services are recognized as follows: events as they
occur and consulting and Web Site ScoreCard as such services are performed.
Revenues from Publications are recognized when publications are delivered.
Unbilled receivables are primarily generated as a result of contractual extended
billing terms offered in connection with Giga's CIS contracts. Giga also records
the related commission obligation upon acceptance of a CIS contract and
amortizes the corresponding deferred commission over the contract period in
which the related CIS revenues are earned. With the consistent application of
these accounting policies as well as growth in CIS contract value and volume,
trade accounts receivable, deferred revenues, unbilled accounts receivable and
deferred commissions are expected to increase.

           Essentially all of Giga's current international operations are
located in the European Community and Canada. Giga operates in the European
Community primarily through wholly owned subsidiaries in the United Kingdom,
France and Germany. These subsidiaries manage direct sales personnel and
distributors in other countries in the European Community as well. In Canada,
Giga utilizes a full-scale sales force and provides business support to these
salespersons through its operations in the United States. Substantially all
Giga's revenues from the European Community are denominated in foreign
currencies, particularly the British pound, while essentially all of Giga's
revenues from Canada are denominated in U.S. dollars. Giga has begun marketing


                                       16
<PAGE>

in Israel, Korea, Italy, Argentina and Brazil through representatives. Revenues
from these representatives have been and are expected to continue to be
denominated in U.S. dollars. To date, however, such revenues have been
insignificant. As a result of fluctuations in exchange rates, transactions
denominated in foreign currencies have inherent financial risk. To date,
however, Giga's cumulative translation adjustments have been slightly favorable,
although there can be no assurance that this trend will continue in the future.
Giga does not currently hedge its exposure to foreign currency adjustments.

           Giga believes that a leading measure of the volume of its CIS
business is the annualized value ("Annualized Value" or "AV") of its Continuous
Information Services agreements in effect at a given point in time. Giga
calculates Annualized Value each month as the cumulative annualized subscription
value payable under the agreements without regard to commencement date, duration
or risk of cancellation. Annualized Value at December 31, 1999 increased 33% to
$58.1 million from $43.8 million at December 31, 1998, while Annualized Value
per client increased 13% to $52,000 at December 31, 1999 from $46,000 at
December 31, 1998. The growth rate of AV declined in 1999 when compared to 1998,
in part due to increases in the AV base in prior years. New opportunities were
postponed in response to uncertainties surrounding the impact of Y2K. The
decline in business from new customers was offset by upgrades to existing
customer contracts. Price pressure has continued into 1999 as Giga's competitors
have adjusted their prices in response to what Giga believes is the superior
value of its services.

           A majority of Giga's annual contracts renew automatically unless the
customer cancels the subscription. Giga's experience is that substantial
portions of customers renew expiring contracts for an equal or greater level of
total CIS fees each year. Approximately 16% of contract value up for renewal in
1999 cancelled, discontinuing all Continuous Information Services, as compared
to 21% in 1998. These cancellation rates do not include contracts lost due to
mergers, acquisitions and bankruptcies. Giga believes that a direct comparison
of its cancellation rate and those of its major competitors may not be
meaningful due in part to Giga's limited operating history and its unified
Advisory Service model (the focus of which is an integrated approach with fewer
contracts/services per customer), in contrast to the multiple-service model of
Giga's major competitors.

           Historically, a substantial portion of new business, upgrades and
renewals for a given year has been generated by Giga in the last two calendar
quarters, and particularly in the last month of the last quarter. As a result of
this quarterly trend in business volume, trade accounts receivable, unbilled
accounts receivable, deferred revenues and deferred commissions typically
increase substantially at quarter end and at the fiscal year end.

           Giga's operating expenses consist of cost of services, cost of
publications, selling and marketing, research and development, general and
administrative, and depreciation and amortization. Cost of services consists
primarily of the direct costs associated with the delivery of Giga's Continuous
Information Services and other services including personnel expenses for
analysts and other personnel, direct expenses for events and conferences, and
royalties to third party information providers. Cost of publications consists of
expenses to create, print and distribute publications. Sales and marketing
expenses include personnel expenses, promotional expenses, and sales
commissions. Sales commissions are typically deferred when paid and expensed as
the related revenue is recognized. Research and development expenses consist of
personnel, consulting and other expenses to develop, enhance and operate
GigaWeb. General and administrative expenses are primarily personnel costs and
fees for professional services supporting the administrative functions of Giga.

           Since its inception, Giga has incurred substantial costs to develop
its Continuous Information Services, establish its GigaWeb system, build a
management team and recruit, employ and train research analysts, sales personnel
and support staff for its business. Giga expects to incur significant losses
through at least fiscal 2000 as Giga continues to expand and develop its
services, products and infrastructure.

           Giga has incurred substantial tax loss carryforwards since inception,
and acquired tax loss carryforwards with its acquisition of BIS, all of which
totaled approximately $76.9 million in the aggregate at December 31, 1999. Due
to the magnitude of these existing tax loss carryforwards, the continuing
anticipated losses through at least 2000 and the substantial uncertainties
associated with its business, Giga is unable to conclude that it is more likely


                                       17
<PAGE>

than not that the deferred tax associated with these tax loss carryforwards will
be realized. Accordingly, this deferred tax asset has been fully reserved. This
valuation allowance will be reduced and the deferred tax asset will be
recognized when and if it becomes more likely than not that the deferred tax
asset will be realized.

     In general, the decreases in the various operating expenses as a percentage
of total revenues are primarily due to leveraging those expenses over increased
revenues derived from a growing customer base.

<PAGE>


FOR THE YEAR ENDED DECEMBER 31, 1999 VERSUS THE YEAR ENDED DECEMBER 31, 1998

           Revenues. Total revenues increased 35% to $52.5 million in 1999 from
$38.8 million in 1998. The increase in total revenues was primarily due to the
increase in revenues from Continuous Information Services.

           Revenues from Continuous Information Services increased 42% to $45.2
million, or 86% of total revenues, in 1999 from $31.8 million, or 82% of total
revenues, in 1998. The increase in revenues was primarily due to growing market
acceptance of Giga's services as evidenced by a 65% increase in Annualized Value
in 1998 which serves as a base for 1999 revenues, the increase in the average
installed value per client from $46,000 at December 31, 1998 to $51,600 at
December 31, 1999, and strong growth in international markets.

           Revenues from Other Services increased 6% to $7.2 million, or 14% of
total revenues, in 1999 from $6.8 million, or 17% of total revenues, in 1998.
The increase was primarily due to sales of Giga's new Web Site ScoreCard
offering in the fourth quarter of 1999.

           Revenues from Publications decreased 59% to $89,000 in 1999 from
$219,000 in 1998. The decrease was due to the continued de-emphasis on this
business activity.

           Cost of services. Cost of services increased 24% to $24.4 million in
1999 from $19.6 million in 1998. The increase in costs was primarily due to the
expansion of analyst staff to support a larger customer base and increased costs
to support increased attendance at and enhancement of GigaWorld IT Forum, and
other Giga conferences.

           Cost of publications. Cost of publications decreased 56% to $178,000
in 1999 from $407,000 in 1998. The decrease in expense was primarily
attributable to lower personnel, reproduction and mailing costs in 1999
resulting from the continued de-emphasis of this business activity.

           Sales and marketing. Sales and marketing expenses increased 18% to
$31.8 million in 1999 from $27.0 million in 1998. The increase was principally
due to higher personnel expenses, higher sales commissions, a full year's
expense for the field analyst program established late in the third quarter of
1998, higher business travel expenses due to changes in sales territories and
increased facilities costs for new sales offices.

           Research and development. Research and development expenses increased
75% to $2.1 million in 1999 from $1.2 million in 1998. The increase was
primarily due to personnel costs and outside consulting fees used in the
development and testing of the newest release of GigaWeb.

           General and administrative. General and administrative expenses
increased 34% to $9.1 million in 1999 from $6.8 million in 1998. The increase in
expense was primarily due to adding infrastructure, hiring additional personnel
and incurring related recruiting costs.

           Depreciation and amortization. Depreciation and amortization expense
increased 29% to $1.9 million in 1999 from $1.5 million in 1998. The increase
was primarily due to increased depreciation costs resulting from computer
equipment and software purchased for new personnel and new deployment of
financial and customer relationship management systems.

           Interest income and expense. Interest income decreased slightly to
$703,000 in 1999 from $736,000 in 1998. Cash balances available for investment
in 1999 decreased throughout the year, while cash balances available for
investment in 1998, particularly in the third and fourth quarters, were
significantly higher resulting from cash proceeds received from Giga's initial
public offering. Interest expense on notes payable and long-term equipment
financing decreased to $204,000 in 1999 from $1.3 million in 1998 due to lower
outstanding principal balances on equipment leases and repayment of $10.0
million in notes payable ("Bridge Notes") in August 1998. The Bridge Notes were


                                       20
<PAGE>

originally issued in April 1998 pursuant to the terms of the Loan and Warrant
Purchase Agreement for bridge financing prior to the Offering (see discussion of
the extraordinary item below).

           Foreign exchange gain/(loss). Foreign exchange losses recorded in
1999 were $768,000, versus gains of $306,000 in 1998 due primarily to unrealized
transaction losses caused by weakening of the German Mark, the French Franc and
the British Pound versus the U.S. Dollar.

           Extraordinary Item. An extraordinary non-cash charge of $707,000, net
of taxes of $0, was recorded in the quarter ended September 30, 1998 for
accelerated accretion of the discount recorded to the Bridge Notes resulting
from the fair market valuation of common stock warrants issued in conjunction
with these Bridge Notes. The accretion was accelerated from future periods as a
result of retiring the Bridge Notes upon completion of the Giga's initial public
offering.


FOR THE YEAR ENDED DECEMBER 31, 1998 VERSUS THE YEAR ENDED DECEMBER 31, 1997

           Revenues. Total revenues increased 97% to $38.8 million in 1998 from
$19.7 million in 1997. The increase in total revenues was primarily due to
increased revenues from Continuous Information Services, but also to an increase
in revenues from events.

           Revenues from Continuous Information Services increased 118% to $31.8
million, or 82% of total revenues, in 1998 from $14.6 million, or 74% of total
revenues, in 1997. The increase in revenues was primarily due to growing market
acceptance of Giga's services as evidenced by a 185% increase in Annualized
Value in 1997 which serves as a base for 1998 revenues, the increase in the
average installed value per client from $35,200 at December 31, 1997 to $46,000
at December 31, 1998, and strong growth in international markets and Advisory
Consulting.

           Revenues from Other Services increased 43% to $6.8 million, or 17% of
total revenues, in 1998 from $4.7 million, or 24% of total revenues, in 1997.
The increase was primarily due to higher revenues generated from the planned
expansion of Giga's events and conferences activities and increased attendance
at Giga's flagship conference, GigaWorld IT Forum. This increase was partially
offset by a decrease in consulting revenues associated with the phase-out of
certain consulting services.

           Revenues from Publications decreased 36% to $219,000 in 1998 from
$344,000 in 1997. The decrease was primarily due to a de-emphasis on this
business activity.

             Cost of services. Cost of services increased 57% to $19.6 million
in 1998 from $12.5 million in 1997. The increase in costs in 1998 was primarily
due to additional staff hired as analysts and field analysts to support a larger
customer base, increased costs in support of expanded offerings in events and
conferences, and other expenses associated with providing Continuous Information
Services to Giga's growing customer base.

           Cost of publications. Cost of publications increased 134% to $407,000
from $174,000 in 1997. The increase in expense was primarily attributable to
greater personnel and production costs in 1998 and lower expenses in 1997
resulting from non-recurring gains from the disposition of two publications.

           Sales and marketing. Sales and marketing expenses increased 38% to
$27.0 million in 1998 from $19.6 million in 1997. The increase was primarily due
to the expansion of Giga's direct sales organization, higher sales commission
expense resulting from increased revenues and increased emphasis on performing
briefings and other lead generation activities.

           Research and development. Research and development decreased 40% to
$1.2 million in 1998 from $2.0 million in 1997. The decrease in 1998 was
primarily due to completing development of GigaWeb's basic functionality in
1997.


                                       21
<PAGE>


           General and administrative. General and administrative expenses
increased 12% to $6.8 million in 1998 from $6.1 million in 1997. The increase in
expense was primarily due to enhancements to infrastructure such as internal
systems, additional personnel and other items to support Giga's growth.

           Depreciation and amortization. Depreciation and amortization expenses
decreased 48% to $1.5 million in 1998 from $2.8 million in 1997. The decrease
was primarily due to cessation of goodwill and leasehold amortization charges in
1998, which were partially offset by increased depreciation costs resulting from
computer equipment purchases for new personnel.

           Interest income and expense. Interest income increased to $736,000 in
1998 from $277,000 in 1997 due to higher average cash balances available for
investment, particularly in the third and fourth quarters of 1998 subsequent to
Giga's Offering. Interest expense increased to $1.3 million in 1998 from
$235,000 in 1997. This increase is primarily due to interest charges on $10.0
million in notes payable ("Bridge Notes") issued in April 1998 pursuant to the
terms of the Loan and Warrant Purchase Agreement for bridge financing prior to
Giga's Offering. These interest charges included cash payments in the amount of
$390,000 and a non-cash charge of $475,000 for accretion of the discount
recorded to the Bridge Notes to value the common stock warrants issued in
conjunction with the Bridge Notes at fair market value. The Bridge Notes were
repaid in full in August 1998 (see discussion of the extraordinary item below).
Additional interest costs were incurred in 1998 on long-term equipment financing
secured by Giga in the fourth quarter of 1997.

           Foreign exchange gain/(loss). Foreign exchange gain/(loss) improved
in 1998 to a $306,000 gain from a $375,000 loss in 1997 due primarily to
unrealized transaction gains caused by strengthening of the British Pound, the
German Mark and the French Franc versus the U.S. dollar.

           Discontinued operations. In 1997, Giga recorded income, net of taxes,
of $1.3 million principally from the settlement of a liability relating to a
long-term, foreign lease and reversal of the provision established for refunds
to potentially dissatisfied customers, all of which had been part of charges
recorded in 1996 to discontinue Giga's BIS market research business. Also in
1997, Giga recognized a gain on the sale of its discontinued econometric
forecasting business, BIS Shrapnel, in the amount of $212,000.

           Extraordinary item. An extraordinary, non-cash charge of $707,000,
net of taxes, was recorded in the quarter ended September 30, 1998 for
accelerated accretion of the discount recorded to the Bridge Notes issued in
April 1998 (see discussion of interest income and expense above). The discount
was recorded to value the common stock warrants issued in conjunction with the
Bridge Notes at fair market value. Accretion charges were accelerated from
future periods due to repayment of the Bridge Notes, in accordance with the
terms of the Loan and Warrant Purchase Agreement for the Bridge Notes, on August
4, 1998, upon completion of Giga's Offering.


LIQUIDITY AND CAPITAL RESOURCES

           Prior to August 1998, Giga funded its operations primarily through
the private placement of equity securities and borrowings under promissory
notes. Giga received aggregate net proceeds of $42.4 million from the private
placement of equity securities since its inception, including $1.9 million (net
of issuance costs of $81,000) from the private placement of Series D Convertible
Preferred Stock and associated Series D warrants in April and May 1998. In April
1998, Giga also issued the Bridge Notes in the aggregate principal amount of
$10.0 million and warrants to purchase an aggregate of 166,666 shares of common
stock at an exercise price of $3.00 per share. The Bridge Notes were issued at a
stated interest rate of 12% per annum. The outstanding principal and interest on
the Bridge Notes became due and payable upon the consummation of Giga's
Offering. On August 4, 1998, warrants to purchase 47,999 shares of common stock
were exercised for cash of $143,997, at an exercise price of $3.00 per share. On
January 27, 1999 and March 8, 1999, warrants to purchase a total of 12,666
shares of common stock were exercised for a cash total of $37,998, at an
exercise price of $3.00 per share These warrants were originally issued in April
1998 pursuant to the Loan and Warrant Purchase Agreement for the Bridge Notes.


                                       22
<PAGE>

           In August 1998, Giga completed its Offering of 3,000,000 shares of
common stock at $12.50 per share. Net proceeds to Giga aggregated approximately
$33.8 million. Giga used $10.2 million of the net proceeds to repay obligations
for principal and remaining accrued interest under the Bridge Notes issued in
April 1998. Also upon the consummation of the Offering, all outstanding shares
of Giga's Series A, B, C and D Convertible Preferred Stock automatically
converted into 4,686,784 shares of common stock.

           At December 31, 1999, Giga had cash, cash equivalents and marketable
securities of $6.2 million. During the year ended December 31,1999, Giga's
capital expenditures totaled approximately $4.7 million, primarily for computer
equipment and applications software. Giga expects that additional purchases of
computer equipment will be made as Giga's employee base and customer base grows.
As of December 31, 1999, Giga had no material commitments for capital
expenditures, and Giga does not currently expect the rate of capital spending to
vary significantly through the end of 2000.

             Net cash used by continuing operations was approximately $9.9
million for the year ended December 31, 1999 and $13.4 million for the year
ended December 31, 1998. This decrease was due principally to a lower net loss
in 1999 and changes in various balance sheet accounts, particularly accounts
receivable and deferred revenues.

           Net cash provided by investing activities was approximately $1.4
million for the year ended December 31, 1999 compared to net cash used by
investing activities of approximately $9.9 million for the year ended December
31, 1998. The change was primarily due to maturities of marketable debt
securities, offset by purchases of marketable debt securities and computer
equipment and applications software in 1999.

           Cash used by financing activities was approximately $124,000 for the
year ended December 31, 1999 compared to approximately $34.1 million of cash
provided by financing activities for the year ended December 31, 1998. Giga
completed its Offering in 1998 as well as its Bridge Note financing and Series D
financing. No further major financing activities were completed in 1999.

                Giga has spent substantial amounts to date on capital and
operating expenditures, which have contributed to an accumulated deficit of
$87.0 million as of December 31, 1999. Furthermore, Giga expects capital and
operating expenditures to increase due to numerous factors, including Giga's
plans to increase marketing efforts for its products and services, the expected
costs to attract and retain qualified employees, the response of competitors to
Giga's services, Giga's plans to develop and market new services and products,
the continued enhancement of the GigaWeb system and the expansion of Giga's
international operations.

           Giga believes that its existing cash, cash equivalents, and maturing
marketable securities and cash expected to be generated from operations, after
the repayment of debts as they become due, will be sufficient to fund Giga's
cash needs until at least the first quarter of 2001.

           However, in the event that Giga encounters difficulties in collecting
accounts receivable, experiences low or reduced subscription renewal rates or
otherwise has revenues that are lower than planned, Giga might require
additional working capital. If necessary, Giga would consider various sources of
financing, including, but not limited to, lines of credit, private placements,
the sale of assets and strategic alliances, but there can be no assurance that
such financing would be available to Giga on terms that are acceptable, if at
all. If adequate funds are not available, Giga may be required to reduce its
fixed costs and delay, scale back or eliminate certain of its services, any of
which could have a material adverse effect on Giga's business, financial
condition and results of operations.

YEAR 2000 COMPLIANCE

           Giga has completed a readiness assessment of internal business
systems critical to its continuing operations and the delivery of services to
its clients and believes that all critical systems are Year 2000 compliant. Giga
believes that the replacement effort specifically due to the Y2K issue is
complete for these software applications and computer hardware. Replacement
systems were either developed internally and/or purchased from third party
vendors. Internally developed systems have been tested for compliance using
simulated Y2K conditions and leap year conditions. Newly purchased systems have
been verified as Y2K compliant by the vendors.

           Giga believes that its products are Y2K compliant, but can not
guarantee that all Y2K related issues have been identified. Giga's readiness
assessment addressed possible issues with GigaWeb and Giga has not experienced
problems with users' ability to access GigaWeb or to search and retrieve GigaWeb
content, including third party content. An upgrade to GigaWeb, GigaWeb 3.0,
released on February 14, 2000 is Y2K compliant.

           Giga also identified significant third party service providers,
vendors, suppliers and customers believed to be most critical to its business
operations and assessed the extent to which Giga's operations are vulnerable if
these vendors and customers experience Y2K issues. Giga is dependent on the
Internet infrastructure for providing reliable GigaWeb access. GigaWeb is an
Internet based information delivery interface and the primary delivery medium
for Giga's Advisory Services. Y2K issues that could affect the power grid and
communications networks that provide the Internet's infrastructure would be
beyond Giga's control. Giga does not currently anticipate that it will
experience any potential adverse effects to its business operations, based upon
its survey of its vendors' Y2K readiness via questionnaires, disclosures
available from their web sites and actual experience to date in 2000. However,
there can be no assurance that these third parties will not experience Y2K
problems, or that such third parties, even if compliant, will not experience
difficulties resulting from Y2K issues affecting their suppliers, service
providers and customers. The possible consequences of Giga's key suppliers or
customers not being Y2K compliant include, but are not limited to, (1) delays in
delivery or an inability to deliver its Continuous Information Services, (2)
vendor or supplier delays in delivery or an inability to deliver goods or
services critical to Giga's continuing operation, (3) delays in or an inability
to bill and collect amounts due from customers, and (4) delays in or an
inability to remit on the part of Giga's customers. As a result, Giga's business
and its results of operations could be materially adversely affected by a
temporary inability to conduct ordinary business for a period of time after such
disruptions.

           Giga has developed appropriate contingency plans in the event that
possible interruptions in business operations occur due to Y2K related issues.

           Based upon Giga's readiness efforts to date, approximately $400,000
of compliance cost has been incurred, most of which were payroll costs for
Giga's information technology groups, incurred exclusively in connection with
its Y2K efforts. These costs were charged to expense as incurred and funded
through operating cash flow. This does not include costs associated with systems
previously scheduled for upgrade or replacement. These costs do not include the
costs associated with contingency plans ($100,000) or the costs for computer
hardware and software replacement which would normally be capitalized
($105,000).

RECENTLY ISSUED ACCOUNTING STANDARDS

           In June 1998, the Financial Accounting Standards Board ("FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting
for Derivative Instruments and Hedging Activities." This statement was amended
by the issuance of SFAS No. 137, "Deferral of the Effective Date of FASB
Statement No. 133," which changed the effective date of SFAS No. 133 to all
fiscal years beginning after June 15, 2000 (fiscal year 2001 for Giga
Information Group). SFAS No. 133 requires that all derivative instruments be
recorded on the balance sheet at their fair value. Changes in the fair value of
derivatives are recorded each period in current earnings or other comprehensive
income, depending on whether a derivative is designated as part of a hedge
transaction and, if it is, the type of hedge transaction. Management of Giga
Information Group anticipates that, due to its limited use of derivative
instruments, the adoption of SFAS No. 133 will not have a significant effect on
the Company's results of operations or its financial position.


Item 7A.  Quantitative and Qualitative Disclosures About Market Risk.

           Interest Rate Exposure

           Based on Giga's overall interest exposure at December 31, 1999,
including all interest rate sensitive instruments, a near-term change in
interest rates would not materially affect Giga's consolidated results of
operations or financial position, within a 95% confidence level based on
historical interest rate movements.

           Currency Rate Exposure

           Foreign currency fluctuations have not had a significant impact on
the comparison of the results of operations for the periods presented. The costs
and expenses of Giga's international subsidiaries are generally denominated in
currencies other than the United States dollar. However, since the functional
currency of Giga's international subsidiaries is the local currency, foreign
currency translation adjustments do not impact operating results, but instead
are reflected as a component of stockholders' equity. To the extent Giga expands
its international operations or changes its pricing practices to denominate
prices in foreign currencies, Giga will be exposed to increased risk of currency
fluctuation.

                        REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of
Giga Information Group, Inc.:


           In our opinion, the consolidated balance sheets and the related
consolidated statements of operations, stockholders' equity (deficit) and cash
flows present fairly, in all material respects, the financial position of Giga
Information Group, Inc. and its subsidiaries (the "Company") at December 31,
1999 and 1998, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1999 in conformity with
accounting principles generally accepted in the United States. In addition, in
our opinion, the financial statement schedules listed in the accompanying index
present fairly, in all material respects, the information set forth therein when
read in conjunction with the related consolidated financial statements. These
financial statements and financial statement schedules are the responsibility of
the Company's management; our responsibility is to express an opinion on these
financial statements and financial statement schedules based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States, which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. THE COMPANY:

           Giga Information Group, Inc. ("Giga") was incorporated on March 17,
1995 in the State of Delaware. Giga's principal business activity is to help
clients make strategic decisions about the technologies, people and processes
needed to excel in e-Business. This is accomplished through a combination of
objective research, advice and continuous technology coaching available
primarily through subscription-based products. Giga derives its revenues
primarily from three sources; Continuous Information Services ("CIS" or
"Continuous Information Services"), which includes its Giga Advisory Service,
ePractices services and Advisory Consulting; Other Services, which include
events, conferences, consulting and Web Site ScoreCard services; and
Publications. CIS consists of IT research and analysis to support customers'
e-Business decisions. Services are distributed primarily through electronic
media, as well as inquiry access to analysts and practitioners and participation
in briefings and conferences, packaged into an annually renewable
subscription-based product. On April 5, 1995, Giga acquired BIS Strategic
Decisions, Inc. and its five foreign affiliates (collectively, "BIS"). On July
6, 1995 Giga acquired a 77.8% equity interest in ExperNet Corporation
("ExperNet") which was owned by Gideon I. Gartner, former Chairman of the Board
of Directors and Chief Executive Officer of Giga, and currently a director, and
David L. Gilmour, currently a director and formerly an officer of Giga, and, on
December 29, 1995, Giga acquired the remaining 22.2% interest.

  Completion of Initial Public Offering

           On August 4, 1998, Giga consummated its Initial Public Offering (the
"Offering") of 3,000,000 shares of its common stock at $12.50 per share.
Aggregate net proceeds to Giga were approximately $33,800,000 after deducting
underwriting discounts and offering expenses payable by Giga. A portion of the
net proceeds of the Offering was used to repay in full the Bridge Notes in the
aggregate principal amount of $10,000,000, plus accrued interest thereon (see
Note 10). Concurrent with the closing of the Offering, all shares of Giga's
Series A, B, C and D Convertible Preferred Stock were converted into an
aggregate of 4,686,784 shares of common stock. (see Note 13).

           Giga is subject to a number of risks similar to other companies in
its industry including a dependence on sales and renewals of subscription-based
services, uncertainty of market acceptance of its services, competition from
other companies including those with greater resources than Giga, dependence on
key individuals, the development of new services and products, protection of
proprietary information and technology and the risks associated with
international operations.


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  Basis of Presentation and Principles of Consolidation

           The consolidated financial statements of Giga Information Group, Inc.
include the accounts of Giga and its wholly owned subsidiaries. All significant
intercompany balances and transactions have been eliminated. Certain prior year
amounts have been reclassified to conform to the current year's presentation.

           Pursuant to the purchase method of accounting, acquired assets and
liabilities were revalued to their fair market value. The excess of the purchase
price over the fair market value of the net assets acquired was recorded as
goodwill.

                          GIGA INFORMATION GROUP, INC.
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


  Foreign Currency Translation

           The accounts of foreign subsidiaries are translated using exchange
rates in effect at period-end for assets and liabilities and at average exchange
rates during the period for results of operations. The local currency for all
foreign subsidiaries is the functional currency. The related translation
adjustments are reported as a separate component of stockholders' equity
(deficit).

 Cash Equivalents and Marketable Securities

           Cash equivalents consist primarily of liquid investments, with
original maturities of 90 days or less, in money market funds which are
convertible to a known amount of cash and bear an insignificant risk of change
in value.

           Marketable securities primarily consisted of corporate and Euro
dollar bonds and medium to short-term notes stated at amortized cost of $800,000
at December 31, 1999 and $6,900,000 at December 31, 1998, which approximates
fair value. These marketable securities have original maturities in excess of
three months. Giga intends to hold these investments to maturity and has
classified these marketable securities as current assets because of contractual
maturities of one year or less.

           As a result of the lease for Giga's headquarters in Cambridge,
Massachusetts, executed in June 1999, $300,000 of cash is held in a restricted,
irrevocable letter of credit, the beneficiary of which is the lessor. The letter
of credit serves as a security deposit for the lease. The lessor may renew the
letter of credit in August 2000 for an amount less than, or equal to, $300,000.

  Concentration of Credit Risk

           Financial instruments, which potentially subject Giga to
concentrations of credit risk, consist primarily of temporary cash investments
in money market funds and trade accounts receivable. Giga places its temporary
cash investments with high credit quality financial institutions in accordance
with its investment policy as approved by its board of directors. Trade
receivables result from contracts with various customers. Giga generally does
not require collateral or other security from these customers. Giga performs
ongoing credit evaluations of its customers and maintains reserves for potential
credit losses. Such losses have historically been within management's
expectations.

  Income Taxes

           Giga recognizes deferred tax assets and liabilities for the expected
future tax consequences of events that have been included in Giga's consolidated
financial statements. Under this method, deferred tax assets and liabilities are
determined based on the difference between the financial statement and tax bases
of assets and liabilities using currently enacted tax rates for the year in
which the differences are expected to reverse. Giga records a valuation
allowance against net deferred tax assets if, based upon the available evidence,
it is more likely than not that some or all of the deferred tax assets will not
be realized.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


  Revenue and Commission Expense Recognition

           Subscription revenues from Continuous Information Services are
deferred and recognized on a pro rata basis over the contract period, generally
one year. Giga's policy is to record a receivable and related deferred revenues
for the full amount of the contract on the date it is signed. Contracts are
generally billable upon signing. Giga also records the related commission
obligation upon the signing of these contracts and amortizes the corresponding
deferred commission expense over the contract period in which the related
Continuous Information Services revenues are earned. In the event the contract
is canceled by the customer, the commission is refundable with respect to the
portion related to the revenue which will not be recognized.

           Revenues from (i) Advisory Services, ePractices services (formerly IT
Practice Services), and Advisory Consulting are aggregated into Continuous
Information Services, (ii) Events and conferences and other services,
principally consulting and Web Site ScoreCard, are aggregated into Other
Services and (iii) Publications are listed separately. Revenues from Other
Services are recognized as follows: events and conferences as they occur and
consulting and Web Site Scorecard as such services are performed. Revenues from
Publications are recognized when publications are delivered.

           Unbilled accounts receivable pertain to the portion of a customer's
service period not yet invoiced in accordance with contractual extended billing
terms offered in conjunction with the Continuous Information Services.

  Property and Equipment

           Property and equipment are stated at cost for items acquired after
the initial acquisition of the respective entities and at estimated fair market
value for those assets in existence at date of acquisition. Expenditures for
maintenance and repairs are charged to expense; expenditures for additions,
renewals and betterments are capitalized.

           Depreciation is computed for financial reporting purposes principally
by use of the straight-line method over the following estimated useful lives:

Computers and related equipment         3 years
Furniture and fixtures                  5 years
Motor vehicles                          4 years
Leaseholds and related improvements     Shorter of economic life or remaining
                                        lease term

           Upon retirement or sale, the cost of assets disposed of and the
related accumulated depreciation is eliminated from the balance sheet and the
resulting gains or losses reflected in income.

  Long-Lived Assets

           Giga regularly reviews long-lived assets for impairment. Any
write-downs are treated as permanent reductions in the carrying amount of the
assets. Management's policy regarding long-lived assets is to evaluate the
recoverability of its assets when the facts and circumstances suggest that these
assets may be impaired. The test of such recoverability is a comparison of the
asset value to its expected undiscounted future cash flows over the remaining
life of the asset. This analysis relies on a number of factors including
operating results, business plans, budgets, economic projections and changes in
management's strategic direction or market emphasis.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


Goodwill

           In 1997, Giga's assessment of the recoverability of goodwill
associated with the ExperNet acquisition indicated a de-minimis level of future
cash flows associated with this business. As such, Giga wrote-off the remaining
unamortized portion of the goodwill resulting in a charge to amortization
expense of $1,025,000. Total amortization expense related to goodwill in that
year was approximately $1,186,000.

 Use of Estimates

           The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect (i) the reported amounts of assets and liabilities, (ii)
disclosure of contingent assets and liabilities at the dates of the financial
statements and (iii) the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

  Historical Net Loss per Common Share

           Giga computes basic and diluted earnings per share in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per
Share." Basic earnings per share is based upon the weighted average number of
common shares outstanding during the period. Common equivalent shares have been
excluded from the computation of diluted loss per share as their effect would be
anti-dilutive. Common equivalent shares result from the assumed exercise of
outstanding stock options and warrants, the proceeds of which are then assumed
to have been used to repurchase outstanding common stock using the treasury
stock method, and the conversion of convertible notes into common stock. As a
result, options and warrants to purchase shares of common stock in the amount of
3,600,117 shares at December 31, 1999, 2,590,993 shares at December 31, 1998,
and 1,637,740 shares at December 31, 1997 were excluded from the calculation of
diluted net loss per common share. Common stock resulting from convertible notes
convertible into 0 shares at December 31, 1999, 0 shares at December 31, 1998
and 93,193 shares at December 31, 1997 were also excluded from the calculation
of diluted net loss per common share. At December 31, 1999, 2,472,071 options
and warrants had an exercise price that was below the average market value per
share of Giga's common stock during 1999.

  Comprehensive Income (Loss)

           Giga has adopted SFAS No. 130, "Reporting Comprehensive Income,"
which establishes standards for the reporting and display of comprehensive
income and its components in general purpose financial statements. Under SFAS
No. 130, Giga is required to display comprehensive income and its components as
part of Giga's full set of financial statements. Comprehensive income is
comprised of net income and other comprehensive income. Other comprehensive
income includes certain changes in equity that are excluded from net income. At
December 31, 1999, accumulated other comprehensive income was comprised solely
of cumulative foreign currency translation adjustments. The individual
components of comprehensive income are reflected in the consolidated statement
of stockholders' equity for the years ended December 31, 1997, 1998 and 1999.

 New Accounting Pronouncements

           In June 1998, the Financial Accounting Standards Board (FASB) issued
SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities."
This statement was amended by the issuance of SFAS No. 137, "Deferral of the
Effective Date of FASB Statement No. 133," which changed the effective date of
SFAS No. 133 to all fiscal years beginning after June 15, 2000 (fiscal year 2001
for Giga Information Group). SFAS No. 133 requires that all derivative
instruments be recorded on the balance sheet at their fair value. Changes in the
fair value of derivatives are recorded each period in current earnings or other
comprehensive income, depending on whether a derivative is designated as part of
a hedge transaction and, if it is, the type of hedge transaction. Management of
Giga Information Group anticipates that, due to its limited use of derivative
instruments, the adoption of SFAS No. 133 will not have a significant effect on
the Company's results of operations or its financial position.


3. ACQUISITIONS:

  BIS Strategic Decisions, Inc. and Affiliates

           On April 5, 1995, Giga acquired 100% of the stock of BIS for $200,000
in cash and a $1,000,000 convertible promissory note (see Note 10). BIS was
engaged in compiling and providing data intensive market research to vendors for
use primarily in planning their product operating and marketing programs. The
acquisition was accounted for as a purchase and, accordingly, the cost
(including acquisition costs of $204,000) was assigned to the tangible and
identifiable intangible assets acquired, including a leasehold for one of the
facilities, and liabilities assumed based upon their estimated fair values at
the date of acquisition. As part of the transaction, an intangible asset
(leasehold) of approximately $1,300,000 was recorded representing the fair value
of payments being made through May 1998 by a former owner of BIS.
In addition Giga acquired current assets of approximately $8,700,000 and
furniture and equipment of approximately $2,000,000 offset by current
liabilities assumed of approximately $12,600,000 (of which approximately
$9,100,000 were deferred revenues), a note payable of $192,000 and a tax
provision of approximately $1,000,000. The excess of the purchase price over the
net assets acquired of approximately $3,059,000 was recorded as goodwill.

  ExperNet

           On July 6, 1995, Giga acquired a majority interest in ExperNet in
exchange for (i) 160,000 shares of Series A Preferred Stock (213,333 shares of
common stock on an as-converted basis), 80,000 shares (106,667 shares of common
stock on an as-converted basis) of which were issued to Mr. Gartner and 80,000
shares (106,667 shares of common stock on an as-converted basis) of which were
issued to Mr. Gilmour and (ii) the issuance to Mr. Gartner of an option to
purchase 53,333 shares of common stock at an exercise price of $1.50 per share
which vested immediately. On December 29, 1995 Giga acquired Mr. Gilmour's
remaining interest in ExperNet in exchange for a $400,000, 6% convertible note
(the "Note") due December 31, 2005 (see Note 10). ExperNet is comprised of a
network of external IT practitioners, and the related interactive software,
which respond to specific customer inquiries. In the transaction, Giga acquired
current assets of approximately $148,000 and furniture and equipment of
approximately $126,000, offset by current liabilities assumed of approximately
$96,000 and long-term debt of approximately $386,000. The acquisition was
accounted for as a purchase; accordingly, the excess of the purchase price over
the net assets acquired of approximately $1,408,000 was recorded as goodwill.

4. RELATED PARTIES:

           During 1997, Giga awarded 17,778 shares of common stock at a fair
value of $3.00 per share to Mr. Gartner in lieu of a payment of cash for
services rendered during 1996 as Chief Executive Officer. Giga recorded as
compensation expense in 1996 the fair value of the common stock awarded to Mr.
Gartner.

           In February 1998, Giga entered into an agreement with Mr. Gilmour, a
director and co-founder of Giga, relating to Mr. Gilmour's continuing
relationship with Giga. As part of this agreement, Giga agreed to early
repayment of a note issued by Giga to Mr. Gilmour in December 1995 in connection
with the acquisition by Giga of Mr. Gilmour's remaining interest in ExperNet
(see Note 3). In addition, the agreement also provided that Giga would receive a
7.5% equity interest in a company newly formed by Mr. Gilmour and would be
granted an irrevocable, royalty-free, worldwide license to use any software,
products or technologies the new company develops during a three year period
commencing on February 1, 1998.

           In December 1998, Giga entered into an agreement with Mr. Crandall, a
director of Giga, for consulting services to be provided over a two-year period
ending June 30, 2000. The agreement provides for total payments of $300,000 for
consulting fees and $48,000 for operational expenses. Also pursuant to this
agreement, Giga granted Mr. Crandall options to purchase a total of 100,000
shares at an exercise price equal to fair market value of $3.625 per share, on
the date of grant. The options will vest over a four-year period contingent upon
services being provided through June 30, 2000 (see Note 15). At December 31,
1998 Giga owed Mr. Crandall $60,000 for consulting fees and $12,000 for
operational expenses for services rendered under this agreement. Payment for
these fees was made in January 1999. All fees payable for services rendered in
1999 were paid in 1999.

           In August 1999, Giga entered into an agreement with Mr. Landry, a
director of Giga, for consulting services to be provided over a two-year period
ending August 31, 2001. Pursuant to this agreement, Giga granted Mr. Landry
options to purchase a total of 25,000 shares at an exercise price of $5.75 per
share, the fair market value on the date of grant. These options will vest over
a two year period contingent upon services being provided through August 31,
2001 (see Note 15).

           An agreement was entered into by and among Giga and two prior owners
of BIS providing for one prior owner, who had guaranteed all payments under a

8. INCOME TAXES:

           Giga has deferred tax assets of approximately $32,434,000 at December

For financial reporting purposes, valuation allowances of $32,434,000 at
December 31, 1999, $30,082,000 at December 31, 1998, and $20,216,000 at December
31, 1997 have been recognized to offset these deferred tax assets until Giga can
conclude that it is more likely than not that these deferred tax assets will be
realized. The valuation allowance increased by approximately $2,352,000 during

</TABLE>



           Giga has available net operating loss carryforwards of approximately
$76,882,000 at December 31, 1999 and $60,716,000 at December 31, 1998, which may
be used to reduce future taxable income. Of these amounts, at December 31, 1999
and 1998, U.S. carryforwards of approximately $66,276,000 and $52,282,000 expire
in various years through 2019, certain non-U.S. carryforwards of approximately
$5,160,000 and $4,781,000 expire in various years through 2004 and the balance
may be carried forward indefinitely. If losses of acquired companies are used to
reduce future taxable income, associated tax benefits will first reduce acquired
goodwill and other non-current intangible assets before being recognized as a
reduction of income tax expense in the period the benefits are realized.
Utilization of the net operating loss carryforwards may be limited pursuant to
the provisions of Section 382 of the Internal Revenue Code of 1986, as amended.

10. BORROWINGS AND LONG-TERM DEBT:

           In connection with Giga's acquisition of BIS, the seller received a
$1,000,000, 5% convertible note due April 5, 1998. The note was convertible into
185,298 shares of common stock. The note plus accrued interest was fully repaid
on April 17, 1998.

           In connection with Giga's acquisition of ExperNet, Giga issued a
$400,000, 6% convertible note to Mr. Gilmour (see also Note 3). The note plus
accrued interest was repaid in two installments, the last of which was in April
1998.

           In June 1997, Giga entered into a loan agreement with a lending
institution collateralized by certain equipment, machinery and fixtures. Under
this agreement Giga received a $1,465,000 loan due in December 2000 with an
effective interest rate of 18.4%. Principal payments required on this loan in
the year 2000 are $527,000.

Loan and Warrant Purchase Agreement

           In April 1998, Giga entered into a Loan and Warrant Purchase
Agreement whereby Giga issued convertible promissory notes with a face value
of$10,000,000, at an annual interest rate of 12.0% (the "Bridge Notes"), and
warrants to purchase up to 166,666 shares of common stock in exchange for cash
proceeds of $10,000,000. The warrants are exercisable at $3.00 per share, for a
period of ten years from the date of the grant. The fair market value of the
warrants was recorded as a discount of $1,182,000 to the Bridge Notes and such
Bridge Notes were recorded at $8,818,000. In August 1998, upon completion of the
Offering, and in accordance with the terms of the Bridge Notes, a portion of the
net proceeds of the Offering was used to repay in full the Bridge Notes in the
aggregate amount of $10,000,000 plus accrued interest thereon.

           A total of $1,182,000 was charged to expense for the year ended
December 31, 1998 to accrete the discount to the Bridge Notes. $707,000 of
accretion was accelerated from future periods due to repayment of the Bridge
Notes on August 4, 1998 (see Note 11).

           On August 4, 1998, warrants to purchase 47,999 shares of common
stock, originally issued in April 1998 pursuant to the Loan and Warrant Purchase
Agreement for the Bridge Notes, were exercised for cash of $143,997, at an
exercise price of $3.00 per share (see Note 15).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


           On January 27, 1999 and March 8, 1999, warrants to purchase a total
of 12,666 shares of common stock, originally issued in April 1998 pursuant to
the Loan and Warrant Purchase Agreement for the Bridge Notes were exercised for
a cash total of $37,998 at an exercise price of $3.00 per share (see Note 15).

           On January 28, 2000 warrants to purchase a total of 38,666 shares of
common stock, originally issued in April 1998 pursuant to the Loan and Warrant
Purchase Agreement for the Bridge Notes, were exercised for cash of $115,998 at
an exercise price of $3.00 per share (see Note 15).

           The weighted average interest rate of outstanding short-term
borrowings was 7.1% for the year ended December 31, 1997. There were no
short-term borrowings as of December 31, 1998 and 1999.


11.  EXTRAORDINARY ITEM:

           $707,000 of accretion, net of taxes of $0, was accelerated from
future periods due to repayment of the Bridge Notes on August 4, 1998 (see Note
10). The accelerated accretion would have been recognized ratably over the six-
month period ending February 1, 1999 had the Company not completed the Offering
and retired the Bridge Notes as required under the terms of the Loan and Warrant
Purchase Agreement for the Bridge Notes.


12. COMMITMENTS AND CONTINGENT LIABILITIES:

           In October 1997, Giga had entered into an invoice factoring
arrangement with a commercial bank under which Giga could borrow up to
$3,000,000. Under this arrangement, the bank would have charged an
administrative fee of 0.5% of each factored invoice and a monthly factoring
management fee of 1.25% of the gross average monthly factored invoices.
Borrowings under the arrangement were collateralized by all of Giga's assets.
Upon the initial utilization of the factoring arrangement, the bank would have
received warrants equal to the value of $125,000 for a class of stock to be
determined and at a price to be determined. The arrangement was automatically
renewable each year. As of December 31, 1999, no invoices had been factored
under the arrangement and the arrangement was not renewed.


13. PREFERRED STOCK:

           The authorized capital stock of Giga includes 5,000,000 shares of
Preferred Stock at December 31, 1999 and 1998. None of the authorized Preferred
Stock at December 31, 1999 has been designated. Of the authorized 16,500,000
shares of Preferred Stock at December 31, 1997, 650,000, 9,000,000 and 4,500,000
shares were designated as Series A, Series B, and Series C Convertible Preferred
Stock. An additional 2,000,000 shares of Preferred Stock were designated as
Series D Convertible Preferred Stock in April 1998. The remaining 350,000 shares
were not designated. Concurrent with the closing of the Offering, all shares of
Giga's Series A, B, C and D Convertible Preferred Stock were converted into an
aggregate of 4,686,784 shares of common stock on August 4, 1998.

increase the authorized number of shares of common stock from 10,000,000 to
28,000,000. In December 1996, Giga amended its Certificate of Incorporation to
increase the authorized number of shares of common stock from 28,000,000 to

1995, Giga sold 636,000 shares of common stock to employees, consultants and
directors at a purchase price of $1.50 per share.

Stock Split

           Giga effected a 1 for 3 reverse stock split of its common stock, par
value $.001 per share (the "common stock"), effective July 29, 1998. All share
and per share data presented herein have been restated to reflect the common
stock split.


15. STOCK OPTIONS AND WARRANTS:

  Stock Options

           In June 1995, Giga adopted the 1995 Stock Plan (the "Prior Stock
Plan"). The Prior Stock Plan was superseded in October 1995 by the 1995 Stock
Option/Stock Issuance Plan (the "1995 Stock Plan"). On August 28, 1996 the Board
of Directors adopted the 1996 Stock Option Plan (the "1996 Stock Plan") to
effectively supersede the 1995 Stock Plan. In May 1999, Giga adopted the 1999
Share Incentive Plan (the "1999 Stock Plan") to effectively supercede the 1996
Stock Plan. The 1995 Stock Plan provided for the granting of options to purchase
and for direct purchases of up to 1,033,333 shares of common stock. The 1996
Stock Plan provided for the granting of options to purchase up to 1,000,000
shares of common stock. The 1999 Stock Plan provides for granting of options,
stock appreciation rights, stock awards, performance awards and stock units up
to 1,000,000 shares directly, and up to 1,500,000 shares that are represented by
awards granted, or to be granted, under any prior plan which are forfeited,
expire, or are cancelled without the issuance of common stock.

           The 1995 Stock Plan, the 1996 Stock Plan, and the 1999 Stock Plan
provide for grants of non-qualifying and incentive options to employees of
(including officers and directors who are employed by Giga), and consultants to
Giga for the purchase of shares of Giga's common stock, generally at the fair
market value determined by the Board on the date of the grant. The 1999 Stock
Plan, as did the 1995 Stock Plan, provides for direct purchases of common stock.
The Board may determine the date on which these shares vest and become
exercisable. Shares purchased as the result of the exercise of these options or
direct purchases under the 1995 Stock Plan are subject to Giga's right to
repurchase such shares upon the occurrence of certain events and at a price
equal to the fair market value as defined on the date of repurchase.

           Options granted under the 1995, 1996, and 1999 stock plans have
variable vesting periods. No options granted under these plans have a term in
excess of 10 years after the date of grant.

<PAGE>

                          GIGA INFORMATION GROUP, INC.
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


           In June 1997, Giga adopted the 1997 Director Stock Option Plan (the
"Director Plan") which provides for the granting of non-qualifying stock options
to purchase up to 50,000 shares of common stock. Under the Director Plan,
non-employee directors are entitled to receive options to purchase 2,000 shares
of common stock on July 1 of each year commencing in 1997. In addition, each
eligible non-employee director would receive an option to purchase 2,000 shares
of common stock upon the initial election to the Board of Directors. The
exercise price of the options, which vest in four equal installments starting
from the date of the grant, will equal the fair market value on the date of the
grant. Each option shall expire 10 years after the date of the grant.

           In January, March, and May 1998 the Board voted to grant 66,535,
319,008 and 93,545 options, respectively, to certain employees at exercise
prices of $3.00, $3.00 and $10.50 per share, respectively. The estimated fair
market value of Giga's common stock at the date of each of these grants was
determined to be $8.40, $8.40 and $12.00 per share, respectively. Accordingly,
such grants were deemed to be compensatory options in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB No. 25").

           Pursuant to an agreement effective July 1998, Giga granted options to
purchase a total of 100,000 shares to a director of Giga for consulting services
to be rendered over a two-year period (see Note 4). The options vest over a
four-year period contingent upon services being provided through June 30, 2000.
Giga recorded compensation expense of approximately $120,000 for the year ended
December 31, 1999 and approximately $91,000 for the year ended December 31, 1998
representing the fair value of the options for the twelve-month period of 1999
and six-month period of 1998 over which services were rendered.

           Pursuant to an agreement effective August 1999, Giga granted options
to purchase a total of 25,000 shares to a director of Giga for consulting
services to be rendered over a two-year period (see Note 4). The options vest
over a two-year period contingent upon services being provided through August
31, 2001. Giga recorded compensation expense of approximately $10,000 for the
year ended December 31, 1999 representing the fair value of the options for the
five-month period of 1999 over which the services were rendered.

            Total option-related compensation expense recognized was
approximately $486,000 for the year ended December 31, 1999, approximately
$375,000 for the year ended December 31, 1998, and $0 for the year ended
December 31, 1997.

Stock Option Repricing

           On November 5, 1998, Giga's Board of Directors, upon recommendation
of the Compensation Committee of the Board of Directors, authorized Giga to
offer to grant to each employee who held an outstanding stock option granted
under Giga's 1996 Stock Option Plan (the "Plan") on May 11, 1998 and August 5,
1998 with an exercise price of $10.50 and $12.125 per share, respectively
(collectively, the "Old Options"), a new stock option (collectively, the "New
Options") under the Plan, in exchange for the cancellation of each such Old
Option. Each such New Option would (a) have an exercise price of $5.00 per
share, (b) be exercisable for one half the number of shares of Giga's common
stock covered by the outstanding unexercised Old Option cancelled in exchange
therefor and (c) have a vesting schedule that is based on the vesting schedule
of the Old Option it replaces except that the date on which the vesting schedule
commences is November 5, 1998. Based on this offer, Giga granted to employees
New Options to purchase an aggregate of 24,617 shares of common stock, at an
exercise price of $5.00 per share in exchange for and upon cancellation of Old
Options to purchase an aggregate of 49,206 shares of common stock with a
weighted average exercise price of $11.08 per share. None of Giga's executive
officers participated in this repricing.

           Options vested and exercisable were 799,105 at December 31, 1999,
554,833 at December 31, 1998, and 488,763 at December 31, 1997.

           In July and October 1995 Giga granted options to purchase a total of
260,000 shares of common stock other than pursuant to the 1995 Stock Plan at an
exercise price of $1.50 per share.

           Giga has adopted the disclosure-only provisions of SFAS No. 123,
"Accounting for Stock Based Compensation," but applies APB No. 25, "Accounting
for Stock Issued to Employees," and related Interpretations in accounting for
stock options. Accordingly, no compensation expense has been recognized for the
issuance of stock options except for grants deemed to be compensatory options,
as previously discussed in this footnote. Pursuant to the required pro forma
disclosure under the fair value method of estimating compensation cost, Giga has
estimated the fair value of its non-compensatory stock options by applying the
Black-Scholes method which considers volatility of the underlying stock using
risk free interest rates based on zero coupon Treasury instruments with
maturities similar to the estimated option term and assuming no dividends.

           Had compensation cost for Giga's stock option plans been determined
based on the Black-Scholes valuation at the grant date for awards in 1997, 1998,
and 1999 consistent with the provisions of SFAS No. 123, Giga's net loss to
common stockholders and net loss per share to common stockholders would have
been increased to the SFAS No. 123 pro forma amounts indicated below (in

are anticipated.

           The weighted average fair value per share of stock options at date of

  Warrants

           In connection with its engagement of a private placement agent for
the sale by Giga of the Series B Preferred Stock, Giga agreed in June 1995 to
issue the placement agent a warrant to purchase 107,876 shares of Series B
(35,959 shares of common stock on an as-converted basis) at an exercise price of
$4.625 per share ($13.875 per share of common stock on an as-converted basis).
In connection with the Series B bridge financing, Giga agreed in August 1995 to
issue the lender a warrant to purchase 285,714 shares of Series B at an exercise
price of $2.345 per share, which warrant was exercised on a cashless basis in
September 1996 for 218,714 shares. Both of these warrants are for a term of five
years, subject to earlier expiration upon the occurrence of certain events. Giga
believes the fair market value of each warrant was nominal.

           In connection with the issuance of Series C, Giga issued warrants to
purchase up to 1,409,127 shares of Series C (551,574 shares of common stock on
an as-converted basis) at an exercise price of $4.50 per share ($13.50 per share
of common stock on an as-converted basis). These warrants are for a term of five
years, subject to earlier expiration upon the occurrence of certain events.

           In connection with the issuance of Series D, Giga issued warrants to
purchase 154,285 shares of Series D (102,857 shares of common stock on an
as-converted basis) at $9.00 per share ($13.50 per share of common stock on an
as-converted basis) pursuant to the Loan and Warrant Purchase Agreement for the
Bridge Notes (see Note 10). The warrants expire on April 5, 2003.

           In April 1998, Giga issued warrants to purchase up to 166,666 shares
of common stock at an exercise price of $3.00 per share pursuant to the Loan and
Warrant Purchase Agreement for the Bridge Notes. The warrants are for a term of
ten years. On August 4, 1998, warrants to purchase 47,999 shares of common stock
were exercised for cash of $143,997, at an exercise price of $3.00 per share On
January 27, 1999 and March 8, 1999, warrants to purchase a total of 12,666
shares of common stock, originally issued in April 1998 pursuant to the Loan and
Warrant Purchase Agreement for the Bridge Notes, were exercised for a cash total
of $37,998 at an exercise price of $3.00 per share.

           On January 28, 2000 warrants to purchase a total of 38,666 shares of
common stock, originally issued in April 1998 pursuant to the Loan and Warrant
Purchase Agreement for the Bridge Notes, were exercised for cash of $115,998 at
an exercise price of $3.00 per share (see Note 10).


16. STOCK PURCHASE PLANS/AGREEMENTS:

           In the period from inception to December 31, 1995, Giga sold 139,999
shares of common stock to certain employees of Giga at $1.50 per share under the
provisions of the 1995 Stock Plan or separate stock purchase agreements.
Employees vest in these shares over four years from their respective dates of
purchase, with 25% vesting on the first anniversary of the purchase and pro rata
thereafter over the remaining 36 months. If an employee who purchased stock
under either the 1995 Stock Plan or separate agreements ceases to be employed by
Giga, Giga at its option may elect to repurchase the employee's unvested shares
at the original cost paid by the employee for such stock and vested shares at a
price equal to the fair market value as determined on the date of repurchase. In
October 1995, Giga sold 40,000 shares of common stock to a director who also
serves as a consultant to Giga for $1.50 per share of which $10,000 was paid in
cash and $50,000 was paid in the form of a non-recourse interest bearing note
due March 31, 1996. In June 1996, Giga canceled the promissory note plus
interest accrued thereunder (totaling approximately $52,000), in lieu of payment
to the director for services rendered to Giga in 1995 (for which the director
was entitled to receive $25,000) and the first six months of 1996 (for which the
director was entitled to receive $30,000) plus interest. These shares are also
subject to certain repurchase rights by Giga in the event that the director
ceases to be either a director of, or consultant to, Giga.

           Pursuant to an agreement entered into in February 1997, Giga issued
to a director of Giga, for services rendered, 16,667 shares of common stock
which vest over six quarterly periods contingent upon services being provided
during the period. Giga recorded as compensation expense $50,000 representing
the fair value of the common stock over the period during which the services
were rendered. Under the agreement, Giga also granted to the director 8,333
non-qualified stock options with an exercise price at the fair market value on
the date of grant which vest over four years. In addition, Giga reimbursed him
$18,000 for operational expenses.

Employee Stock Purchase Plan

           On May 10, 1999, Giga adopted the 1999 Employee Stock Purchase Plan
("the 1999 Purchase Plan") which enables employees to purchase shares of Giga
common stock. The 1999 Purchase Plan is administered by the Compensation
Committee of the Board of Directors. Under the 1999 Purchase Plan, eligible
employees enroll in a two-year offering period and purchase shares at the end of
two, one-year, purchase periods. Offering periods begin on the first day of
January, April, July and October of each year. The purchase price is 85% of the
lesser market value on the first day of the offering period or the last day of
each purchase period. The maximum number of shares an employee can purchase in a
purchase period is 5,000 shares. An employee's rights under the 1999 Purchase
Plan terminate upon voluntary withdrawal from an offering or termination of
employment. Giga reserved 750,000 shares, plus an annual increase to be added on
the first day of the fiscal year beginning in the year 2000, equal to the lesser
of (i) 750,000 shares, (ii) one percent of the outstanding shres on such date,
or (iii) a lesser amount determined by the Board of Directors. During 1999,
offering periods began on July 1 and October 1. As of December 31, 1999, no
shares have been purchased under the 1999 Purchase Plan.

17. EMPLOYEE BENEFIT AND DEFERRED COMPENSATION PLANS:

           In the United States, Giga maintains a Savings and Retirement Plan
(the "401 (k) Plan") under Section 401 of the Internal Revenue Code. In 1997,
Giga amended its 401(k) Plan specifying that employees can enter the plan on the
date of hire or the first day of the month. In 1998, Giga amended its 401(k)
Plan specifying that employees can enter the plan on the first day of the month
following the date of hire. Employees must have attained the age of 21. In prior
years, employees were eligible to participate in the 401(k) Plan who worked a
minimum of one year and had attained the age of 21. Giga matched by 25% that
portion representing the first 3% of an employee's base salary and by 50% that
portion representing the next 3% of an employee's base salary. Effective in
1997, the employer contributions are discretionary after considering business
results at the conclusion of each plan year. Giga has not made discretionary
contributions to the 401(k) Plan during the years ended December 31, 1998 and
1999.

           In the United Kingdom, Giga maintains a defined contribution plan.
All permanent employees who have attained the age of 20, and are not
contributing to a personal pension plan, are eligible to participate. Giga
matches a percentage of employee contributions, which are invested at each
participant's discretion in a choice of three funds. The employer matching
percentage is determined within defined age ranges. Giga's match totaled $39,000
during the year ended December 31, 1999, $22,000 during the year ended December
31, 1998 and $2,000 during the year ended December 31, 1997.


18. DISCONTINUED OPERATIONS:

           On June 25, 1996, Giga announced the discontinuation of the BIS
market research business. In connection with the discontinuance of such
operations, Giga terminated the personnel employed in developing and compiling
the data-intensive BIS market research products, ceased operations at two of its
licensed facilities in England and entered into contracts with two independent
IT service providers engaged to fulfill Giga's obligations to customers of BIS
under certain existing subscription agreements, all of which expired by June
1997. The contracts with the service providers required that Giga pay a
percentage of the remaining contract value in exchange for their fulfillment of
Giga's obligations. In 1996, a total of approximately $623,000 was paid to the
service providers to fulfill the obligations remaining under the discontinued
operations. A provision of approximately $1,187,000 was established for probable
refunds in connection with dissatisfied clients. At December 31, 1996 a total of
approximately $720,000 remained in the provision for refunds. The contracts with
the providers also require the service providers to pay royalties to Giga upon
the renewal of contracts by them. Through December 31, 1997, no royalties had
been earned or received. The results of these operations prior to June 25, 1996
have been classified as discontinued operations and prior year financial
statements have been restated to reflect the discontinuance. A charge of
approximately $2,315,000 (net of taxes of approximately $158,000) was recorded
in 1996 for the loss on disposition of the operations consisting primarily of
rent and compensation. Included within the charge was a provision related to the
operations at two facilities in England which, based on the market for subleased
properties at the time, approximates the present value of the expected expenses
of these facilities for two and one-half years plus fifty percent of the
expected expenses over the remaining life of the leases and a provision for the
severance benefits payable to the terminated employees.

           A gain of approximately $1,101,000 was recorded in 1997, mainly
comprised of a reversal of the provision for future lease commitments and
related expenses for two facilities in England and the provision which was
established for refunds to dissatisfied customers.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


           On December 20, 1996 Giga elected to discontinue its Australian
econometric forecasting business, BIS Shrapnel, and commenced discussions with
the management team for the purchase of the entire business. The entire business
was sold in July 1997 to the management team for AU$407,500, or approximately
$293,000 at the time of sale. A gain of approximately $212,000 was recognized on
the disposition after giving effect to transaction costs.

19. SEGMENT INFORMATION:

           Giga has determined that it operates in one reportable segment,
advisory services. This determination is based on Giga's method of internal
reporting and the similarities among its products and services. Giga's products
and services are similar with regard to financial performance and business risk,
targeted customer market, the methods used to market, sell and provide its
products and services to customers and their purpose which is to provide
customers with objective analyses and advice on developments and trends in IT
and e-Business.

           Revenues from the products and services within, and in support of,
Giga's advisory services are presented in detail in its Consolidated Statements
of Operations. No single customer accounted for more than 10% of the Company's
revenues for the years ended December 31, 1999, 1998, and 1997.

           The accounting policies used to evaluate performance are the same as
those described in the "Summary of Significant Accounting Policies" (Note 2).

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


20. SUBSEQUENT EVENTS

           On February 18, 2000, Giga's Board of Directors adopted a Stockholder
Rights Plan ("Plan") designed to protect Giga stockholders in the event of
takeover activity that would deny them the full value of their investment.

           Terms of the Plan provide for a dividend distribution of one right
for each share of Giga Common Stock to holders of record at the close of
business on March 3, 2000. The rights will become exercisable only in the event,
with certain exceptions, a person or group of affiliated or associated persons
accumulates 15 percent or more of Giga's voting stock, or if a person or group
announces an offer to acquire 15 percent or more. A stockholder who owns 15
percent or more of Giga's voting stock as of February 18, 2000 will not trigger
this provision unless the stockholder thereafter acquires an additional one
percent or more of the outstanding stock. The rights will expire on February 18,
2010.

           Each right will entitle the holder to buy one one-hundredth of a
share of a new series of preferred stock at a price of $95. In addition, upon
the occurrence of certain events, holders of the rights would be entitled to
purchase either Giga stock or shares in an "acquiring entity" at half of market
value. Further, at any time after a person or group acquires 15% or more (but
less than 50%) of Giga's outstanding voting stock, subject to certain
exceptions, the Board of Directors may, at its option, exchange part or all of
the rights (other than rights held by the acquiring person or group, which would
become void) for shares of Giga's common stock, initially on a four-for-one
basis.

           Giga generally will be entitled to redeem the rights at $.01 per
right at any time prior to the time there has been a public announcement of the
acquisition of a 15 percent position in its voting stock, subject to certain
exceptions.
