ITEM 1. BUSINESS
 
GENERAL
 
MapInfo Corporation (the "Company" or "MapInfo") designs, develops, markets,
licenses, and supports mapping software products, application development
tools, and data products, together with a range of consulting, training and
technical support services. These products and services enable business users
worldwide to correlate, visualize, and analyze corporate data using the common
theme of geography to help solve business problems related to sales and
marketing analysis, site selection, asset management, risk analysis, routing
and logistics, among others. By overlaying corporate data on any of the
thousands of digital maps sold by the Company or its data partners,
organizations can use geographic or demographic information as a framework for
viewing, interpreting and managing data.
 
MapInfo's business strategy emphasizes the development of a broad range of
software products for business mapping and spatial analysis, marketed through
multiple channels of distribution. Products range from stand-alone software
for the desktop PC to development tools for creating custom applications for
the PC, client/server, Internet and other networked environments. MapInfo(R)
software products operate in a multi-platform environment and permit file
sharing of geographic and demographic data across products and platforms.
There are currently over 400 third-party applications for use with MapInfo
software.
 
Although MapInfo operates in one industry segment (see Note 12 of the Notes to
Consolidated Financial Statements), the Company is organized into three
strategic business units to focus R&D activities, product development, and
worldwide market strategies on current and emerging developments in the
marketplace. The Desktop Business Unit is focused on the development of the
Company's desktop products and deployment of packaged applications and product
extensions of the core product, MapInfo Professional(R). The Enterprise
Business Unit is responsible for the development and deployment of all
enterprise products, including developers' tools, such as ProServer(TM),
MapInfo MapX(TM) and MapInfo MapXsite(TM), and database applications with
SpatialWare(TM). The Information Business Unit is responsible for the
development of MapInfo's data products and the Company's Web site as a sales
and delivery channel for MapInfo's full product line.
 
The Company's predecessor was incorporated in New York in 1986, ("MapInfo New
York"). On November 6, 1997, MapInfo New York merged with and into the
Company, then a wholly-owned subsidiary of the Company, for the sole purpose
of reincorporating MapInfo New York as a Delaware Corporation, and the Company
succeeded to all of the rights and liabilities of MapInfo New York. All
references herein for MapInfo or the Company refer to MapInfo New York for
periods or events prior to November 6, 1997.
 
BACKGROUND
 
In today's business environment, organizations are under constant competitive
pressure to acquire and retain customers, reduce costs, and improve operating
efficiencies. Many businesses are turning to information technology to meet
these challenges, yet in many cases organizations are overwhelmed by the vast
amount of data available to them, or have difficulty accessing and organizing
data to effectively make decisions. In order to meet their business goals and
manage the information overload, many companies are re-engineering common
business practices by turning to networked systems and distributed computing,
and providing information to managers at all levels within an organization.
 
Applying geography to business practices has become an increasingly important
way to leverage information technology across an organization. A significant
amount of all corporate data has a location component, such as an address or
postal code. By using the location component and positioning data on maps or
analyzing this data according to geographic relationships, MapInfo products
enable users to use data to make meaningful decisions by revealing patterns,
relationships and trends not previously recognized with conventional analysis
and reporting
 
                                       1
<PAGE>
 
methods. For many businesses, this approach provides a cost-effective solution
with improved operational efficiencies.
 
PRODUCTS AND SERVICES
 
The Company offers a range of mapping software and data products, in addition
to services that include consulting, training, and technical support for end
users, developers and original equipment manufacturers ("OEMs").
 
SOFTWARE
 
DESKTOP PRODUCTS:
 
  MAPINFO PROFESSIONAL
 
  MapInfo Professional is a full-featured, customizable mapping software
  package for businesses and GIS analysts. It includes a wide range of data
  visualization, management and analysis tools, plus open database
  connectivity ("ODBC") to directly access corporate databases. It is
  compatible with Microsoft's object linking and embedding ("OLE")
  technology, allowing MapInfo maps to be easily integrated into other
  applications. MapInfo Professional can be customized for specific industry
  uses.
 
  MAPBASIC(R)
 
  MapBasic is a programming environment used by information system ("IS")
  organizations and third-party developers to create customized mapping
  applications for use with MapInfo Professional. MapBasic can be used to
  focus or extend the functionality of MapInfo Professional, modify the user
  interface to a specific business need, automate routine operations, and
  integrate MapInfo Professional with other applications.
 
  PACKAGED APPLICATIONS
 
  Packaged Applications are complete solutions which combine MapInfo
  Professional with third-party applications to solve specific business
  problems. The first of these products, MAPINFO PROALIGN(TM), is a territory
  management solution introduced in September 1997, that allows sales and
  marketing managers to automatically re-align sales territories, optimize
  workloads and analyze customer and competitive information.
 
ENTERPRISE PRODUCTS:
 
  SPATIALWARE
 
  SpatialWare is MapInfo server technology that stores and manages complex
  spatial data along with traditional data types in corporate relational
  database servers for ISO SQL3-based spatial querying. With it, users are
  able to instantly incorporate mapping for visualization and analysis within
  enterprise applications and data warehouse environments to support business
  decisions. SpatialWare is available on Oracle(R), Informix(R), and IBM DB2.
 
  MAPINFO MAPX
 
  MapInfo MapX is an OCX component used by developers to embed mapping
  functionality into new and existing applications. Developers can work from
  within familiar object oriented development environments such as Visual
  Basic(R), PowerBuilder(R), and Delphi(TM) to add a mapping object to an
  application. Users can access mapping functionality from their familiar
  business applications created by developers.
 
                                       2
<PAGE>
 
  MAPINFO MAPXSITE
 
  MapInfo MapXsite is a complete mapping package that enables Web developers
  and Internet service providers to embed "dealer locator" capabilities in
  Web sites. MapXsite was introduced in July 1997 and was first deployed on
  Wal-Mart's Web site for finding the nearest stores, products and services
  to a customer's location.
 
  PROSERVER
 
  ProServer is a suite of software and developer tools for creating
  Internet/intranet mapping applications. With ProServer, the data and
  application reside on a server for easy updating and distribution. It
  allows end users to access mapping through standard Web browsers or other
  custom interfaces using Internet protocols. The suite includes MapInfo
  Professional and MapBasic, in addition to the ProServer software.
 
INFORMATION PRODUCTS
 
The Company's Information Products include a wide range of data products that
are developed and used with its software products and the Corporate Web site
which acts as the Internet distribution channel.
 
MAPINFO DATA PRODUCTS:
 
The Company's Data Products fall into three categories:
 
 .  Geocoding, address-matching and data cleansing products
 .  Geographic and geo-demographic information products
 .  Software utilities
 
GEOCODING PRODUCTS
 
Geocoding products assign latitude/longitude coordinates to corporate data
containing geographic references so that the data can be accurately displayed
on a map and analyzed geographically. MapInfo's geocoding products prepare
data for use in MapInfo Professional and other mapping applications.
MAPMARKER(R) and MAPMARKER PLUS are geocoding, address-matching and cleansing
products marketed in the United States. They are available as a client or
server-side product or as an ActiveX/OCX, and include a developer kit for
creating customized geocoding solutions to fit into specific business
processes, such as point-of-sale or geo-demographic analysis applications.
MapMarker can batch geocode entire databases or be used interactively in real
time to geocode addresses as they are entered in a geocoding DataBlade module
on an INFORMIX(R) Universal Data Option. The Company also markets geocoders
for use in the United Kingdom and Australia.
 
GEOGRAPHIC AND GEO-DEMOGRAPHIC INFORMATION PRODUCTS
 
The Company offers a broad line of worldwide geographic and geo-demographic
information products for use with MapInfo software. These products compile
extensive quantities of data derived from public and private sources. The
Company often re-engineers and aesthetically enhances this data so that the
resulting data product conforms to MapInfo standards and can be used more
effectively with MapInfo software products. The Company typically pays
royalties to third parties with respect to sales of data products that are
developed by outside sources.
 
The Company's geographic and geo-demographic data products include:
 
  Street Products. The Company's street-based data products are based on
  files available from the United States Census Bureau. The Company's
  selection of street maps includes streets, highways, water boundaries,
  railroad tracks, bridges and town boundaries. Address ranges are also
  included in metropolitan areas. By overlaying any geocoded database with a
  street address field, a user can display each record as a point in its
  relative location. In addition to data for the United States, street-level
  files are available for Canada,
 
                                       3
<PAGE>
 
  Germany, Italy, Belgium, Sweden, the Netherlands, Switzerland, France,
  Austria, Spain, Poland, Australia, Israel, Mexico, Brazil, Argentina,
  Chile, Columbia, Venezuela, and Uruguay.
 
  Boundary Files. The Company's boundary maps allow users to shade, color or
  add symbols that represent important information or business data contained
  in these areas. These boundaries include ZIP Code areas, states, counties,
  census tracks, block groups, Congressional districts and telecommunications
  boundaries, such as area codes, exchanges, cellular and PCS market
  boundaries in the United States. Boundaries for other countries include
  postcodes, provinces, cantons, landers, and prefectures.
 
  Geo-demographic Data. The Company offers thousands of map-compatible geo-
  demographic data files for use with MapInfo software. Data available from
  the Company includes information relating to population, income, retail
  activity, employment, consumer trends and preferences, lifestyles,
  manufacturing and other business data, Yellow Pages, and banking and
  telecommunications data. Geo-demographic data, especially CLUSTERPLUS(TM)
  lifestyle segmentation data, when combined with MapInfo software, create a
  cutting edge means for identifying the best new markets for both consumer
  and business-to-business products and services.
 
  Other International Data. The Company offers digital map data with respect
  to Canada, the European Community, Asia Pacific and other international
  regions. For example, the Company offers maps showing all Canadian
  highways, European postal code boundaries for 17 countries in Western
  Europe and prefecture boundaries for China.
 
SOFTWARE UTILITIES
 
The Company offers additional software utilities that translate and convert
certain types of GIS or CAD files for use in MapInfo applications. These
utilities allow data from other formats to be registered and used in MapInfo
software and allow differing earth coordinate systems to be aligned with each
other for accuracy. The Company also offers a translator application
programming interface ("API") to third parties for development of data format
translators.
 
THE INTERNET:
 
MAPINFO CORPORATE WEB SITE
 
The Company continues to maintain and expand its corporate Web site
(www.mapinfo.com). The site serves dual purposes in that it is a vast resource
of information on the Company and its products and services, as well as a
launching pad to other sites the Company has created, such as
www.mapexpress.com, www.mapx.com and www.mapxsite.com. Activity on all the
sites continues to grow as information becomes more specialized and targeted.
MapInfo's presence via the Internet is allowing the Company to bring prospects
closer to a sale and to attract new audiences.
 
MAPINFO EXPRESS(TM) SUPERSTORE
 
To establish a vehicle for electronic commerce, the Company created the
MapInfo Express Superstore on its Web site. This vehicle is a cost-effective
distribution channel for the Company's products and Partner offerings, and
establishes a base for delivering mapping services via the Internet. The
Internet continues to offer new opportunities to build brand awareness and add
value for customers and prospects.
 
PRODUCT DEVELOPMENT
 
The software industry is characterized by extremely rapid changes in
technology, which require continuous expenditure on product research and
development to enhance existing products and create new products. The Company
believes that the timely development of new products and ongoing enhancements
to existing products is essential to maintain its competitive position in the
marketplace. The Company is committed to an open
 
                                       4
<PAGE>
 
systems, standards-based product architecture to provide software products
that can be integrated into existing mainstream business environments and be
adaptable as environments change.
 
Most of the Company's software products are developed internally. Internal
development allows the Company to maintain close technical control over
products in terms of enhancements and modifications based on customer needs,
and allows the Company to create a family of products that provides natural
migration paths for customers as their mapping needs change.
 
MARKETING & DISTRIBUTION
 
The Company has established multiple distribution channels to reach an array
of industries while simultaneously addressing specific vertical markets.
Distribution channels include an indirect channel of value-added resellers,
OEMs and distributors, a corporate accounts sales force, and a telemarketing
sales group. The Company has field sales offices in twelve locations in North
America, three locations in Europe, and three locations in Australia. The
Company also has direct sales offices in China, Hong Kong and Taiwan.
 
The Company's direct sales and marketing organization is complemented by a
network of corporate partners including resellers, system integrators, OEMs
and distributors who purchase the Company's products at a discount for resale.
These partners may provide training, consulting services, application
development, customization, and data products to end users. Outside North
America, distributors are the predominant channel of distribution. These
distributors generally build their own value-added reseller network in
addition to directly selling data products and consulting services.
 
The Company also has an established network of strategic alliances with
leading software companies including Microsoft(R), Oracle and Informix. The
Company conducts joint sales and marketing programs and has technology
agreements with these companies to integrate mapping into their solutions and
gain exposure to a wider range of potential customers.
 
To build corporate identity and generate demand in support of the sales
effort, the Company conducts comprehensive marketing programs, which include
advertising, public relations, trade shows, direct mail, MapWorld(R) Magazine,
Web-based promotions, and ongoing communications to customers about new
products. The Company additionally offers cooperative advertising and other
marketing support to its value-added reseller partners. The Company sponsors
an annual reseller's conference, which generates communication and support for
the reseller network. The Company also sponsors European and Asia Pacific
partner conferences, which foster communication and support on an
international level.
 
The Company is focused on information discovery--that is, delivering products
and solutions that help transform data into meaningful decisions. In addition
to desktop applications, organizations today are seeking more widespread
deployment of critical business applications and are demanding mapping and
geo-spatial solutions for networks, including the Internet, intranets and data
warehouses. They are also demanding tools that integrate mapping functionality
into other applications, as well as tools to manage complex geo-spatial data.
The Company has successfully expanded its product offerings beyond the desktop
market to the enterprise and Internet/intranet markets. Sales to the
enterprise and Internet/intranet markets are directed to different decision-
makers within customer organizations and require different selling and
marketing programs than are used in the desktop market.
 
COMPETITION
 
The Company encounters significant competition from various companies, in US
and foreign markets, offering mapping software. These competitors include
Environmental Systems Research Institute, AutoDesk, Small World, Tactician and
others.
 
INTELLECTUAL PROPERTY
 
The Company regards its software as proprietary and attempts to protect it
with a combination of copyright, trademark and trade secret laws, employee and
third party non-disclosure agreements, and other methods of
 
                                       5
<PAGE>
 
protection. Despite these precautions, it may be possible for unauthorized
third parties to copy certain portions of the Company's products or reverse
engineer or obtain and use information the Company regards as proprietary.
While the Company's competitive position may be affected by its ability to
protect its proprietary information, the Company believes that the trademark
and copyright protections are less significant to the Company's success than
other factors, such as the knowledge, ability and experience of the Company's
personnel, MapInfo name recognition and ongoing product development and
support.
 
The Company supplies MapInfo software products primarily under shrinkwrap
licenses. Shrinkwrap licenses are not negotiated with or signed by individual
licensees and take effect upon the opening of the product package. Certain
provisions of such licenses, including provisions protecting against
unauthorized use, copying, transfer and disclosure of the license program, may
be unenforceable under the laws of certain jurisdictions. In addition, the
laws of some foreign countries do not protect the Company's proprietary rights
to the same extent as do the laws of the United States. Accordingly, the
Company supplies its MapInfo products using a hardware access key in many
countries. There can be no assurance that third parties will not assert
infringement claims against the Company in the future with respect to current
or future products. Any such assertion could require the Company to enter into
royalty arrangements or result in costly litigation.
 
MapInfo, MapInfo Professional, MapMarker, MapWorld and MapBasic are registered
trademarks or services marks of MapInfo Corporation in the United States.
ProServer, MapInfo MapX, MapInfo MapXsite, SpatialWare and ProAlign are
trademarks of MapInfo Corporation. All other trademarks mentioned herein are
the trademarks of their respective owners.
 
EMPLOYEES
 
At September 30, 1997, the Company had 362 full-time employees. The Company's
employees are not represented by any collective bargaining organization and
the Company has never experienced a work stoppage.
 
ITEM 2. PROPERTIES
 
The Company leases two premises totaling approximately 102,000 square feet of
office space in the Rensselaer Technology Park in Troy, New York, which leases
expire in 2002 and 2004. These offices house the corporate headquarters, the
principal research and development center and the principal sales, marketing
and administrative staff for the Americas. The Company leases office space of
approximately 11,000 square feet in Windsor, England, which houses the
European headquarters. The lease on this facility expires in 2012. In
addition, the Company leases eight sales offices in the United States, one
research and development center in Canada, two sales offices in Europe and
three sales offices in Australia.
 
ITEM 3. LEGAL PROCEEDINGS
 
The Company is not a party to any material legal proceedings.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
On September 24, 1997, the Company held a Special Meeting of Stockholders for
the purpose of approving the Company's reincorporation from New York to
Delaware (the "Special Meeting"). The Special Meeting was adjourned to
September 30, 1997 and further adjourned to October 31, 1997. The stockholders

  ------------------------------------------------------------------
</TABLE>
 
In 1997, the increase in revenues was due to increased unit sales of software
and data products in Europe and the Americas. Revenues from Asia-Pacific
remained constant compared to 1996, reflecting a change in the Company's
distribution model in Japan effective February 1997. Approximately half of the
increase in total Company revenues in 1997 resulted from sales of new or
recently introduced enterprise products, including SpatialWare, MapX, and
ProServer. Services revenues declined in 1997 primarily due to increased
reliance on value added resellers in the Americas to meet customer consulting
requirements.
 
In 1996, revenues increased due to increased sales in Asia-Pacific and Europe,
including the increased sales resulting from the acquisition of the Company's
master distributor in Australia in August 1995. This increase offset a decline
in revenues in the Americas primarily due to decreased unit sales of some
software and data products, a shift in the mix of products sold toward lower-
priced products, decreased technology licensing and development fees, and
decreased services revenues.
 
The Americas represented 70%, 52% and 50% of Company revenues in 1995, 1996
and 1997, respectively. In addition, Asia-Pacific represented 12%, 24% and
22%, and Europe represented 18%, 24% and 28% of Company revenues in 1995, 1996
and 1997, respectively. Sales to one distributor in the Asia-Pacific region
represented 7%, 9% and 7% of total net revenues in 1995, 1996 and 1997,
respectively. The next scheduled expiration/renewal date for the distribution
contract with this distributor is December 31, 1998.
 
The Company's operating results are affected by exchange rates. Approximately
10%, 25% and 27% of the Company's revenues were denominated in foreign
currencies during 1995, 1996 and 1997, respectively.

  ---------------------------------------------------------------
</TABLE>
 
Cost of revenues as a percentage of net revenues decreased in 1997 due to an
increased percentage of sales from high margin software products, volume
license arrangements, and lower material costs. The percentage increased in
1996 compared to 1995 due to lower technology licensing and development fees
income, the cost of bundling other software products with MapInfo
Professional, and the write-off of obsolete inventory.

</TABLE>
 
Research and development costs increased in 1997 primarily due to increased
headcount and other costs resulting from the purchase of SpatialWare
technology, increased costs for translating and localizing MapInfo products
into foreign languages, and lower capitalization of product development costs.
The increases in 1996 expenses resulted primarily from increased headcount,
higher compensation costs following a competitive review, and higher
depreciation and amortization expense in support of the Company's efforts to
accelerate product development. Research and development headcount increased
from 83 at the end of fiscal 1995 to 89 at the end of fiscal 1996 and to 97 at
the end of fiscal 1997. Capitalized product development costs were $594,
$1,316, and $333 (exclusive of additional capitalized product development
costs resulting from the purchase of SpatialWare technology) in 1995, 1996 and
1997, respectively. These amounts represented 9%, 16% and 3% of total research
and development costs in 1995, 1996 and 1997, respectively.
 
Selling and marketing expenses increased in 1997 primarily due to increases in
headcount and other costs associated with the introduction, marketing and sale
of SpatialWare and increases in sales and marketing activities in Europe.
These were offset by the reductions in other sales and marketing costs in the
Americas and in Asia-Pacific, primarily as a result of closing a support
office in Tokyo. Sales and marketing costs associated with the SpatialWare
product line accounted for nearly half of the increase in sales and marketing
expenses in 1997. In 1996, selling and marketing expenses increased primarily
due to operating costs in Australia and the costs of an office in Tokyo to
support the Company's master distributor in Japan.
 
General and administrative expenses increased in 1997 primarily due to
increased compensation costs, higher professional fees and increased MIS costs
in the Company's domestic and international operations. The increase in 1996
was primarily attributable to operating costs in Australia and increased costs
in the United Kingdom in support of the expansion of international operations.

Other income consisted mainly of interest income of $1,141, $1,206 and $1,357
in 1995, 1996 and 1997, respectively. Interest income was derived from
investment activities. Interest income was offset by interest expense, foreign
currency losses and other expenses totaling $106, $231 and $426 in 1995, 1996
and 1997, respectively. Increases in interest income, resulting from a shift
in the investment portfolio from tax exempt to taxable investments, were
offset by increases in foreign exchange losses and miscellaneous expense
items.

(Dollars in thousands, except earnings per share)
 
The 1997 benefit from income taxes was attributable to the current year pre-
tax loss and permanent differences arising from research and development tax
credits and tax exempt interest income earned before the investment portfolio
was substantially reinvested into taxable investments. In 1996, the decrease
in the effective tax rate was primarily due to an increased portion of pre-tax
income derived from tax-exempt investment income.

FINANCIAL CONDITION
 
The Company's cash and short-term investments totaled $31.2 million at
September 30, 1997, and represented 61% of total assets. The portfolio is
invested primarily in short-term, liquid securities.
 
MapInfo has no material long-term debt. The Company has a $20 million credit
facility with a bank that expires in December 1999. The Company also has a $10
million line of credit with a bank that expires in January 1998. The Company
anticipates that the line of credit will be renewed for a one-year period on
substantially similar terms. There were no outstanding borrowings under either
facility at September 30, 1997 and 1996.
 
In November 1996, the Company's Board of Directors authorized the repurchase
of up to $5.0 million of the Company's common stock. This authorization
expired on September 30, 1997. During the period from June 1997 to September
30, 1997, the Company repurchased 80,000 shares totaling $878.
 
Net cash from operating activities was $3,318, $6,099 and $3,502 in 1995, 1996
and 1997, respectively. Net cash from (used for) investing activities was $72,
$5,377 and ($5,847) in 1995, 1996 and 1997, respectively. During 1997 $2,369
was used for capital expenditures, primarily to upgrade computer equipment
worldwide, for a new accounting/information system and for leasehold
improvements in expanded facilities in the United Kingdom and Germany. The
Company also capitalized $1,440 of product development costs resulting from
the purchase of SpatialWare technology and purchased $1,705 of short-term
investments. Net cash from (used for) financing activities included the
proceeds from the exercise of stock options and share purchases under the
Company's Employee Stock Purchase Plan, which totaled $806, $593 and $765 in
1995, 1996 and 1997, respectively. In 1997, these proceeds were primarily
offset by purchases of ($878) of treasury stock.
 
Pursuant to an Agreement dated October 2, 1996, the Company acquired an
exclusive, worldwide license to distribute and sub-license SpatialWare
technology from Unisys Corporation. The Company is obligated to make
contingent cash payments, up to a maximum of $1,500, to Unisys. Such
obligation arises following the achievement of a specified threshold of
cumulative net revenues of the SpatialWare business as defined in the
Agreement. No royalties were earned or accrued as of September 30, 1997.
 
Management believes existing cash and short-term investments together with
funds generated from operations should be sufficient to meet the Company's
operating requirements for the next twelve months.
 
THE DATA CONSULTANCY ACQUISITION
 
Pursuant to a Share Sale and Purchase Agreement dated December 2, 1997, the
Company acquired all of the issued share capital of The URPI Group Limited, an
English company trading as The Data Consultancy ("The Data Consultancy") and
engaged in the sale of market analysis solutions and information products in
the United

Kingdom. The purchase price was approximately $4,200 in cash and stock. In
addition, the Company is obligated to make a contingent cash payment in
October 1998, up to a maximum of approximately $1,000, based on the financial
performance of The Data Consultancy in the year following the acquisition. The
acquisition will be accounted for as a purchase and, accordingly, the Company
will include The Data Consultancy's results of operations in its financial
statements from the date of acquisition.
 
OUTLOOK: ISSUES AND RISKS
 
This Annual Report on Form 10-K contains forward-looking statements. For this
purpose, any statements contained herein that are not statements of historical
fact may be deemed to be forward-looking statements. Without limiting the
foregoing, the words "believes," "anticipates," "plans," "expects," and
similar expressions are intended to identify forward-looking statements. The
following important factors, among others, could cause actual results to
differ materially from those indicated by forward-looking statements made in
this Annual Report on Form 10-K and presented elsewhere by management from
time to time.
 
In addition to the other information in this Annual Report on Form 10-K, the
following issues and risks, among others, should be considered in evaluating
MapInfo's outlook and future.
 
NEW PRODUCTS AND TECHNOLOGICAL CHANGE. The mapping software and information
business is characterized by extremely rapid technological change, evolving
industry standards, and frequent new product introductions. These conditions
require continuous expenditures on product research and development to enhance
existing products and to create new products. The Company believes that the
timely development of new products and continuing enhancements to existing
products is essential to maintain its competitive position in the marketplace.
During fiscal 1997, the Company introduced a number of new products, including
SpatialWare, ProServer and MapX. The Company's future success depends, in
part, upon customer and market acceptance of these new products. Any failure
to achieve acceptance of these and other new product offerings could have a
material adverse effect on the Company's business and results of operations.
There can be no assurance that the Company will successfully complete the
development of new or enhanced products or successfully manage transitions
from one product release to the next.
 
COMPETITION. The Company encounters significant competition in the market for
business mapping systems worldwide. Increased competition may lead to pricing
pressures that could adversely affect the Company's gross margins. Prices of
software in Europe and Asia are generally higher than in the Americas to cover
localization costs and higher costs of distribution. Such price uplifts could
erode in the future.
 
RELIANCE ON THIRD PARTIES. The Company relies in part on strategic partners
and independent developers for the development of specialized data products
that use MapInfo software. Failure by such strategic partners or independent
developers to continue to develop such data products, or changes in the
contractual arrangements with such strategic partners or independent
developers, could have a material adverse effect on the Company's business and
results of operations.
 
EXPANSION TO ENTERPRISE MARKET. The Company has previously marketed its
products primarily in the desktop mapping market. The Company has recently
expanded its product offerings beyond the desktop market to the enterprise and
Internet/intranet markets. Sales to the enterprise and Internet/intranet
markets are directed to different decision-makers within customer
organizations and require different selling and marketing programs than are
used in the desktop market. The failure of these products to achieve market
acceptance could have a material adverse effect on the Company's business and
results of operations.
 
PRICES. Future prices the Company is able to obtain for its products may
decrease from previous levels depending upon market or competitive pressures
or distribution channel factors.

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

(Dollars in thousands, except earnings per share)
 
INTELLECTUAL PROPERTY RIGHTS. The Company regards its software as proprietary
and attempts to protect it with a combination of copyright, trademark and
trade secret laws, employee and third party non-disclosure agreements, and
other methods of protection. Despite these precautions, it may be possible for
unauthorized third parties to copy certain portions of the Company's products,
reverse engineer or obtain and use information the Company regards as
proprietary. In addition, the Company's shrinkwrap licenses, under which the
Company licenses its products, may be unenforceable under the laws of certain
jurisdictions; and the laws of some foreign countries do not protect the
Company's proprietary rights to the same extent as do the laws of the United
States. Any misappropriation of the Company's intellectual property could have
a material adverse effect on the Company's business and results of operations.
Furthermore, there can be no assurance that third parties will not assert
infringement claims against the Company in the future with respect to current
or future products. Any such assertion could require the Company to enter into
royalty arrangements or result in costly litigation.
 
COST OF REVENUES. Cost of revenues varies with the mix of technology
development and licensing fees, product revenues, and services revenues, as
well as with the distribution channel mix. Changes in the revenue mix, as well
as the distribution model, may affect cost of revenues as a percentage of net
revenues in the future.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS. Revenues outside the Americas
increased from 30% of revenues in fiscal 1995 to 48% of revenues in fiscal
1996 and to 50% of revenues in fiscal 1997. The international portion of the
Company's business is subject to a number of inherent risks, including the
difficulties in building and managing international operations, reliance on
financial commitments from certain international distributors, difficulties in
localizing products and translating documentation into foreign languages,
fluctuations in the value of international currencies, fluctuations in
import/export duties and quotas, and unexpected regulatory, economic, or
political changes in international markets. Changes in international business
conditions could have a material adverse effect on the Company's business and
results of operations.
 
YEAR 2000 COMPLIANCE. The Company's salable products rely on software
applications. The Company also relies on systems of other parties in regards
to its business, accounting and operational software. The Company believes
that its salable products, as well as its significant business, accounting and
operations software are year 2000 compliant. However, there can be no
assurance that the Company will not experience difficulties with the
conversion of these systems. The Company's business, financial condition or
results of operations could be materially adversely affected by the failure of
its systems and applications or those operated by other parties to properly
manage dates beyond 1999.
 
ACCOUNTING STANDARDS. Statement of Financial Accounting Standards No. 128-
"Earnings Per Share" is effective for fiscal years ending after December 15,
1997. The Company will adopt this Statement in fiscal year 1998. The following
represents the basic and dilutive earnings per share amounts had the Company
been required to adopt this statement for the years ended September 30, 1995,
1996 and 1997:

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of MapInfo Corporation and Subsidiaries
 
We have audited the consolidated financial statements and the financial
statement schedule of MapInfo Corporation and Subsidiaries listed in Item
14(a) of this Form 10-K. These financial statements and financial statement
schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
financial statement schedule based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of MapInfo
Corporation and Subsidiaries as of September 30, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended September 30, 1997 in conformity with
generally accepted accounting principles. In addition, in our opinion, the
financial statement schedule referred to above, when considered in relation to
the basic financial statements taken as a whole, present fairly, in all
material respects, the information required to be included therein.

                     MAPINFO CORPORATION AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Nature of Operations
 
  The Company designs, develops, markets, licenses and supports business
mapping software products, application development tools, and data products,
together with a range of consulting, training and technical support services.
These products are sold through multiple distribution channels, including an
indirect channel of value-added resellers and distributors, a corporate
account sales force, and a telemarketing sales group. The Company markets its
products worldwide through sales offices in North America, Europe, Australia,
China, Hong Kong, Taiwan and Japan.
 
 Basis of Consolidation
 
  The consolidated financial statements include the accounts of MapInfo
Corporation and its wholly-owned subsidiaries. Significant intercompany
balances and transactions have been eliminated.
 
 Use of Estimates in the Preparation of Financial Statements
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Cash and Cash Equivalents
 
  For the purpose of the cash flows statements, the Company defines cash and
cash equivalents as cash and investments with original maturities of three
months or less.
 
 Inventories
 
  Inventories are stated at the lower of cost or market as determined on the
average cost method and consist primarily of computer media, user manuals and
software packaging supplies.
 
 Short-term Investments
 
  The Company's short-term investments consist of debt securities with
maturity dates of one year or less. In accordance with SFAS No. 115, debt
securities have been classified in the accompanying consolidated balance
sheets as held-to-maturity securities and are reported at amortized cost
because the Company has the positive intent and ability to hold these debt
securities to maturity. Market value is determined by quoted market prices.
 
 Property and Equipment
 
  Property and equipment is stated at cost. Depreciation is calculated using
the straight-line method over the estimated useful lives of the assets (two to
ten years) for financial reporting purposes and accelerated methods for tax
purposes. When assets are sold, retired, or otherwise disposed of, the
applicable costs and accumulated depreciation are removed from the accounts
and the resulting gain or loss is recognized.
 
 Product Development Costs
 
  Product development costs, including product enhancements, are capitalized
after technological feasibility has been established. These costs are reported
at the lower of unamortized cost or net realizable value and are being
amortized on a straight-line basis over two to five years, the estimated
economic life of the products.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Annual amortization under the straight-line method is greater than the ratio
of current gross revenue to total expected product revenues method.
Amortization expense is classified as research and development expense in the
accompanying consolidated statements of income.
 
 Intangible Assets
 
  Intangible assets represents the excess of cost over the fair value of net
assets acquired. Intangible assets are being amortized using the straight-line
method over five to seven years. The Company continually evaluates the
existence of goodwill impairment on the basis of whether the goodwill is fully
recoverable from projected, undiscounted net cash flows of the related
business unit.
 
 Revenue Recognition
 
  Product revenue: Revenue from software license and technology development
fees is recognized upon the later of shipment of product or completion of
significant obligations to customers, if collectibility of the resulting
receivable is probable. Upon the recognition of revenue, all costs associated
with insignificant obligations are accrued.
 
  Postcontract customer support (PCS): Generally, PCS that is bundled with an
initial licensing fee is for one year or less and is recognized together with
the initial licensing fee on delivery of the software, if collectibility of
the resulting receivable is probable and enhancements and the costs of
providing these services are expected to be insignificant. When PCS is sold
under separate agreements, the revenue is recognized ratably over the term of
the agreement.
 
 Reserve for Returns
 
  The Company as a matter of policy provides the buyer the right to return
certain products within a stated period ranging from 30-60 days, for a refund
of the purchase price or replacement of the product. Accordingly, the Company
accrues for estimated future returns.
 
 Income Taxes
 
  Deferred income taxes are recognized for the tax consequences of "temporary
differences" by applying enacted statutory tax rates applicable for future
years to differences between financial statement and tax basis of existing
assets and liabilities. The effect of tax rate changes on deferred taxes is
recognized in the income tax provision in the period that includes the
enactment date.
 
  Business tax credits are recorded by the flow-through method of accounting,
whereby they are applied as a reduction of income tax expense in the year the
credits are utilized.
 
 Foreign Currency
 
  The assets and liabilities of the Company's foreign subsidiaries are
translated at year-end exchange rates, and the income statements are
translated at the average rates of exchange prevailing during the year. Gains
or losses resulting from translating non-U.S. currency financial statements
are accumulated in a separate component of stockholders' equity. Gains and
losses from foreign currency transactions are included in net income.

under which a maximum of $20 million can be borrowed for a two year period and
then converted into a three year term loan. Interest is at the bank's prime
rate, LIBOR plus 1.5%, or a fixed rate, at the Company's option. The credit
facility contains certain financial ratio covenants and is collateralized by
the common stock and distribution agreements of certain subsidiaries. None of

development center, the principal sales, marketing and administrative staff
for the Americas. These leases contain a nominal escalation in rental payments
over the term of the lease, and in addition to monthly lease payments, the
Company is responsible for such costs as real estate taxes and maintenance.
The Company may acquire these facilities through the termination of these
leases at a negotiated purchase price. The leases expire in 2002 and 2004. The
Company also leases space of approximately 11,000 square feet in Windsor,
England, which houses the European headquarters. The lease on this facility
expires in 2012.
 
Future minimum rental payments required under operating leases that have
initial or remaining non-cancelable lease terms in excess of one year as of
September 30, 1997 decline from $2.2 million in 1998 to $1.6 million in 2002.
 
Total rent expense for the years ended September 30, 1995, 1996 and 1997 was
approximately $722, $1,665 and $2,133, respectively.
 
 Year 2000 Compliance:
 
  The Company's salable products rely on software applications. The Company
also relies on systems of other parties in regards to its business, accounting
and operational software. The Company believes that its salable products, as
well as its significant business, accounting and operations software are year
2000 compliant. However, there can be no assurance that the Company will not
experience difficulties with the conversion of these systems. The Company's
business, financial condition or results of operations could be materially
adversely affected by the failure of its systems and applications or those
operated by other parties to properly manage dates beyond 1999.

There are no valuation allowances recorded against the Company's deferred tax
assets, as it is more likely than not that all future tax benefits will be
realized against future taxable income. However, the amount of deferred tax
assets, considered realizable could be reduced in the near term if estimates
of future taxable income are reduced.

 Stock Option Plans
 
  The Company has stock option plans for directors, officers, and all
employees, which provide for non-qualified and incentive stock options. The
option exercise price is the fair market value at the date of grant. Options
granted prior to July 1996 vest over 5 years and 1 day and expire 10 years from
the date of grant. Options granted after July 1996 vest over 4 years and expire
10 years from the date of grant. At September 30, 1997, options for 216,861
shares were vested and 1,070,096 were available for future grants under the
plans.
 
In February 1997, the Company repriced certain options granted to employees and
officers. Option holders, holding options to purchase 561,363 shares with
exercise prices ranging from $9.88 to $19.00 per share were issued new options
on a one-for-one basis with an exercise price of $9.76 per share. This exercise
price was based on the closing price of the Company's common stock on January
31, 1997, plus ten percent. The closing price on that date was $8.875. In March
1996, the Company repriced certain options granted to employees under this plan
on a four-for-five basis. Option holders, holding options to purchase an
aggregate of 327,177 shares with exercise prices ranging from $17.25 to $35.25

The Company follows APB Opinion No. 25, Accounting for Stock Issued to
Employees, to account for stock option and employee stock purchase plans. No
compensation cost is recognized because the option exercise price is equal to
the market price of the underlying stock on the date of grant. Had
compensation cost for these plans been determined based on the Black-Scholes
value at the grant dates for awards as prescribed by SFAS No. 123, Accounting
for Stock-Based Compensation, pro forma net income (loss) and earnings (loss)
per share would have been:
