PART I
ITEM 1. BUSINESS.
General
MathSoft, Inc. ("MathSoft" or the "Company") develops, markets and supports
software productivity tools and services for the technical calculation and data
analysis markets comprised of technical professionals, researchers, students and
educators.

Mathcad , the Company's principal technical calculation product, was first
released in fiscal 1987 and can be used by desktop and laptop computer users to
perform calculations from the simple to the elaborate, and then document the
results. Mathcad offers technical professionals, educators, and students an
interactive, intuitive, easy-to-modify alternative to their traditional
calculation methods such as pencil and paper, scratchpads and calculators.
The market for technical calculation software includes technical professionals,
such as electrical, mechanical and civil engineers, scientists, mathematicians,
researchers, technicians and analysts, as well as educators and students who
regularly are required to perform technical calculations. These users often
refer to a wide range of published materials containing formulas or data, which
can be used in solving technical problems.

In 1992, the Company expanded its technical calculation software product line by
introducing Electronic Books as add-on products to Mathcad. These books deliver
extensive off-the-shelf technical information, such as formulas and data, which
is critical to technical problem solving. Through the use of MathSoft's
proprietary "live document interface ," these books provide the Mathcad user
with on-screen access to interactive technical information. This enables a
Mathcad user to either perform calculations in the book itself or to transfer
formulas, data and results to Mathcad for instant calculation and analysis. The
Company delivers electronic versions of industry leading reference works from
nationally and internationally recognized publishers, in addition to internally
authored works. In addition, the Company licenses its Mathcad and Electronic
Book authoring technology to third party publishers for use in creating
interactive Electronic Books which are marketed and distributed by such third
party publishers as stand-alone products.

In May 1993, the Company opened an international office located in the United
Kingdom to broaden distribution of its products. For the twelve months ended
December 31, 1998, international sales of all technical calculation and data
analysis software products and services represented approximately 28% of total
revenues (refer to Footnote 7 & 8 for further detail).

In June 1993, the Company introduced a new product line through its wholly owned
subsidiary, Statistical Sciences, Inc., now referred to as MathSoft's Data
Analysis Products Division ("DAPD"). DAPD develops and markets advanced data
analysis software products and services based on "S," a computer language
designed for statistics applications. DAPD's principal product is S-PLUS , an
interactive computing environment that provides both a full-featured graphical
data analysis system and an object-oriented language. The Company acquired this
business on June 30, 1993, through the acquisition of substantially all of the
assets and business of Statistical Sciences, Inc., a Washington corporation.
For the twelve-months ended December 31, 1998, worldwide sales of data analysis
products and services represented approximately 36% of total revenues.

The market for data analysis software consists principally of professional
scientists, engineers, statisticians and business analysts as well as educators
and students. Data analysis products are used in such fields as biomedical
technology, quantitative financial analysis and risk assessment, environmental
science and engineering, industrial and market research, and process control.



In November 1995, the Company acquired TriMetrix, Inc. ("TriMetrix"). MathSoft
complemented its technical calculation product line with the addition of Axum ,
a Windows-based technical charting and data analysis product acquired with
TriMetrix, which transforms, manipulates and sorts data sets to perform both
simple and advanced analysis. Axum has been redesigned to link seamlessly with
Mathcad and the Axum technology is now a key component of S-PLUS for Windows.

In June 1996, the Company released StudyWorks! for Math and StudyWorks! for
Science targeted specifically toward high school and non-technical college
students and educators. Both StudyWorks products offer an interactive learning
environment and assist students in both mastering math and science concepts and
creating professional looking homework and lab reports in addition to allowing
both educators and students the ability to collaborate on projects. In
September 1996, the Company announced the release of StudyWorks! Schools, an
instructional edition of the StudyWorks for Math and StudyWorks for Science
software, which offers teachers a tools-based, interactive teaching and learning
environment.

In November 1996, the Company acquired acroScience Corporation ("acroScience").
MathSoft integrated visual modeling and programming technology acquired from
acroScience into Mathcad.

In April 1997, the Company expanded its data analysis product line by
introducing MathSoft StatServer, a warehouse-independent platform for
distributing statistical analysis and graphics to business professionals and
analysts over corporate Intranets. StatServer uses the S-PLUS technology to
create deployable intelligent analytics for an organization and integrates with
existing data storage and desktop applications.

In December 1997, the Company changed its fiscal year end from June 30 to
December 31. Accordingly, the Company began a new twelve-month fiscal year on
January 1, 1998. The six-month period resulting from this change, July 1, 1997
through December 31, 1997, is referred to as the "Transition Period."
The Company's goals are to continue to meet the expanding calculation and data
analysis needs of technical professionals, to provide students and educators
with software tools that can be used for learning and for solving real-world
problems and to develop new products for the growing needs of businesses. The
Company will continue to broaden the appeal for all of its products to existing
and new markets through technological innovation, in such areas as ease-of-use,
mathematical power, graphics and deployability, and to continue to expand its
distribution as new products for new markets are introduced.

The Company was incorporated in Massachusetts in October 1984 under the name
Engineering Specific Products Corp. and changed its name to MathSoft, Inc. in
January 1986. The Company's principal executive offices are located at 101 Main
Street, Cambridge, Massachusetts 02142, and its telephone number is (617)
577-1017.


Products

Technical Calculation Software Products

MathSoft publishes a range of technical calculation and software products that
allow users to perform calculations and create publication-quality documents on
personal computers. Its principal product in this category, Mathcad, is to
technical professionals what spreadsheets have proven to be for business
professionals. Mathcad can be used by desktop computer users to perform
technical calculations, from the simple to the elaborate. An innovative feature
of Mathcad is its ability to allow the user to electronically access and
manipulate formulas and data available in the Company's Electronic Books and
Extension Packs. Electronic Books provide on-screen libraries of
industry-leading reference work, user guides, solution templates, and
educational materials while Extension Packs provide additional functionality for
advanced users. StudyWorks, the most recent addition to the Mathcad product
line, was designed as an integrated learning tool combining math, text, graphs
and graphics for the high school and college market. StudyWorks helps students
master math and science concepts, get better grades and create
professional-looking homework and lab reports.

Mathcad

Mathcad's broad appeal lies in its use of MathSoft's proprietary "live document
interface" technology. This permits users to calculate on a computer in much the
same way that they would on a scratchpad where equations can be written
anywhere, using real math notation, and erased, changed and moved. A scratchpad
can show a variety of expressions such as formulas, words, graphs, data,
equations and pictures. Mathcad works in a similar free-form manner by
literally turning a computer screen into a live worksheet and therefore provides
a very intuitive interface to perform a wide range of numeric or symbolic
calculations, but Mathcad has one distinct advantage over a real scratchpad - it
calculates.

When using Mathcad, the computer screen initially appears blank, like a
scratchpad. Using the keyboard and the mouse, the user begins by placing the
cursor anywhere on the screen and then starts typing. To create a formula, the
user types keystrokes such as +, /, or * or uses a mouse to click on a symbol
palette. As the user types, Mathcad automatically formats the formulas in
standard mathematical notation and instantly calculates the results. To create a
graph, the user selects the graph symbol from the palette and defines the
parameters of the graph. As with an electronic spreadsheet, Mathcad instantly
updates results as changes to variables or formulas are made. Text may be added
anywhere. Multi-page presentation quality documents can be printed, complete
with text, graphics, tables and equations. Its free-form interactive
environment makes Mathcad ideal for formulating ideas, setting up problems and
evolving solutions and sharing both the process and the results through printed
documents, e-mail, and the World Wide Web.

Mathcad is used as a calculator for simple formulas, as a more elaborate solver
for equations formally linked within a "live document," as a technical report
generator, as a live charting facility, and as a mathematical teaching
environment. Mathcad also provides an interface to online technical reference
works. Mathcad performs numeric and symbolic calculations in the real and
complex domain, solves systems of linear and non-linear equations, and performs
iterative calculations.

Electronic Books

An extension of the Mathcad product line, Electronic Books deliver information
and solutions in an interactive form to Mathcad users. Electronic Books provide
the user with on-screen libraries of technical data combined with Mathcad's
capacity to utilize and manipulate the raw data through its "live document
interface." This enables the user to search the book for material, use
hyperlinks to jump to related sections within the work, and calculate problems
and manipulate data using formulas and data contained in the work. A key feature
of MathSoft's Electronic Books is that the material is live and interactive,
enabling a Mathcad user to apply the formulas or data from the book either by
performing calculations in the book itself or by transferring the formulas or
data, or results, to Mathcad for calculation and analysis. Without the
Electronic Book, the user must manually key in entire formulas from published
sources before using the software to solve equations. The book may contain
reference information (e.g., the properties of various materials and standard
formulas), solutions for standard engineering problems, tutorials on selected
topics, or educational courseware. Additionally, Mathcad's "live document
interface" supports the inclusion of sound and video components.

In addition to internally authored works, the Company delivers electronic
versions of industry-leading reference works from nationally and internationally
recognized publishers. The agreements by which the Company licenses content for
Electronic Books from publishers typically provide for a non-exclusive license
at an agreed-upon royalty rate, and continue for a term of five to seven years
unless extended by mutual agreement.

The Company also licenses its Mathcad and Electronic Book authoring technology
to third party publishers for use in creating interactive Electronic Books which
are marketed and distributed by such third party publishers as stand-alone
products. Users are not required to use Mathcad to access these interactive
Electronic Books.

Extension Packs

Extension Packs provide additional functionality to Mathcad in the areas of
signal processing, wavelets, image processing, and advanced optimization. Once
installed, the functions are seamlessly integrated with the Mathcad function set
allowing the user to see results immediately and explore the effects of changing
parameters in mathematical routines.

Axum

In November 1995, the Company acquired TriMetrix, Inc., a software company
located in Seattle, Washington and the developer of Axum software. Axum is a
Windows-based advanced technical graphing and data analysis software which
offers scientists and engineers in the technical professional market, including
Mathcad users, the advanced charting tools needed for creating compelling,
highly visual presentations and publication-quality documents. Users can
transform, manipulate and sort data sets to perform both simple and advanced
analysis. Axum has also been redesigned to link seamlessly with Mathcad.

StudyWorks

StudyWorks! for Math and StudyWorks! for Science, productivity software for high
school and college students and their teachers, was designed as a rich learning
environment that helps students understand math and science problems, complete
and check a variety of solutions, and print out great looking lab reports and
homework papers. Each product is a three-in-one combination of an application,
rich interactive content and two-way Internet access. StudyWorks is based on a
powerful graphical calculation and document preparation tool and includes rich
multimedia encyclopedias of math and science formulas and key concepts in
algebra, geometry, earth science, chemistry, pre-calculus, physics, calculus and
statistics. Users also receive built-in links to the Company's StudyWorks home
page, which allows high school students, college students and teachers to
participate in virtual study groups and discussion forums, pick up Homework
Hints and link to related sites on the World Wide Web.

StudyWorks! for Schools, released in September 1996, was designed as the
instructional edition complement to the Company's StudyWorks for Math and
StudyWorks for Science software products. StudyWorks for Schools allows
teachers to integrate software and distance learning approaches into their
current math and science curriculum and provide students with an
"active-learning," content-rich learning tool. StudyWorks for Schools
integrates seamlessly with existing curricula, works with graphing calculators,
includes a content-rich math and science reference library, and comes with a
Teachers Resource Guide featuring sample lesson plans, classroom presentations,
lab and homework exercises and tips for maximizing the use of the technology.
It also connects teachers and students to each other via the Web-based
Collaboratory for a variety of distance learning applications, including virtual
study groups, online tutoring, and the dissemination of class or lab notes,
problem sets, exams and solutions.



Data Analysis Software Products

S-PLUS

On June 30, 1993, the Company acquired Statistical Sciences, Inc., a software
company located in Seattle, Washington. The Company's principal product in this
category, S-PLUS, is an advanced, exploratory data analysis and statistical data
mining solution for technical and business professionals who need sophisticated
analysis and visualization capabilities. Based on the object-oriented "S"
programming language licensed from Lucent Technologies Inc., S-PLUS enables
users to perform exploratory data analysis, graphics, statistics, visualization
and mathematical computing in the Windows and UNIX environments. The primary
advantage of S-PLUS lies within the "S" Language. The "S" language is the only
modern object-oriented language created specifically for data visualization and
exploration, statistical modeling and programming with data. This interactive
language environment gives users immediate feedback at every stage of their
analysis.




Modules

To complement S-PLUS, the Company offers add-on modules that work with S-PLUS
and provide additional "S" language functions for specialized data analysis
purposes.

StatServer

In April 1997, the Company expanded its data analysis product line by
introducing MathSoft StatServer. StatServer enables corporations to leverage
existing client/server and internet/intranet technologies and deploy statistical
expertise throughout an organization. StatServer is data warehouse-independent
and integrates seamlessly with all standard database and data warehouse formats.
The robust database support provides the tools for advanced analysis and data
visualization of the most popular relational databases. With StatServer, basic
statistical models and data visualization capabilities are built and stored in a
central server for access by non-technical users, who can apply these analytical
techniques from a single and familiar client to understand or interpret key data
sets. Using StatServer, professionals in diverse fields such as finance,
biomedicine and manufacturing can use familiar tools such as Excel, Netscape or
Powerbuilder to access corporate data resources and perform data analysis
without becoming experts in statistics or users of statistical tools.
StatServer moves beyond the capabilities of report writers, spreadsheet
applications and stand-alone data analysis software, representing a significant
advancement in decision support and data mining technology.

Marketing and Sales

Technical Calculation Software Products

The Company's market for technical calculation software products consists of two
significant groups of end users: technical professionals and academia (educators
and students). End users within the technical professionals group span numerous
fields and include electrical, mechanical and civil engineers, scientists,
mathematicians, researchers, technicians and analysts. The education market
consists of secondary, undergraduate and graduate educators and students in many
technical disciplines. The Company's products are currently used as tools for
diverse purposes, from back-of-the-envelope calculations to bridge design and
genetic engineering.

MathSoft reaches domestic customers of Mathcad primarily through a network of
educational and commercial third party resellers and distributors. To
complement this network, the Company has a domestic telesales organization
focused on sales to the registered installed base as well as on lead generation,
prospect qualification and sales of site license agreements and network
licenses. In addition, Mathcad upgrades are primarily marketed to the Company's
registered installed base via direct mail. For the twelve months ended December
31, 1998, domestic sales through distributor and reseller channels accounted for
approximately 51% of total domestic sales of technical calculation software
products, with the balance of such sales through either installed base direct
mail, the Company's telesales operations, electronic mail, or the Company's
webstore. One distributor, Ingram Micro, accounted for 13% and 12% of net
revenues, respectively, for the year ended December 31, 1998 and the six-month
period ended December 31, 1997. Ingram Micro also accounted for 14% and 12% of
net revenues in the years ended June 30, 1997 and 1996, respectively. Ingram
Micro is a distributor of our products primarily to various resellers and retail
accounts, none of which comprised more than 10% of the Company's total revenues
during the periods mentioned.

Internationally, all technical calculation software products are marketed
primarily through a network of resellers and distributors. Mathcad upgrades are
marketed through distributors as well as to the registered installed base via
direct mail. For the twelve months ended December 31, 1998, international sales
through resellers and distributors accounted for substantially all international
sales of technical calculation software products.

Data Analysis Software Products

The Company's market for data analysis products consists principally of
professional and academic scientists, engineers and statisticians. The product
is used in such fields as biomedical technology, quantitative financial analysis
and risk assessment, environmental science and engineering, industrial and
market research, and process control.

The Company reaches domestic customers of its data analysis products both
through its domestic telesales organization and an outside sales team. Leads
are generated from advertising, Public Relations, seminars and tradeshows and
these leads are then pursued by the telesales organization.
Internationally, the Company reaches customers of its data analysis products
primarily through a network of resellers and distributors. In the United
Kingdom, the Company sells directly to end-users.











Customer Technical Support

Technical Calculation Software Products

MathSoft provides technical support to its domestic customers by phone, fax,
mail and automated technical support via a telephone response system and the
Company's home page on the World Wide Web. A technical support staff of
engineers located in Cambridge provides solutions to installation and basic
usage problems as well as assistance on advanced technical and mathematical
issues. The Company provides this support free of charge to individual
end-users and offers a Premium Support Plan to its corporate customers. The
Company currently provides technical support for its Mathcad, StudyWorks and
Axum product lines and offers a variety of product add-ons.

International customers who purchase product from distributors receive first
line technical support from their respective local distributor. A technical
support staff of engineers, located in the Company's United Kingdom sales and
marketing office, is available to support the distributors.

Data Analysis Software Products

Technical support for the S-PLUS product line is provided to domestic customers
by a staff of engineers located in Seattle. Support is only available to
customers who purchase an annual maintenance and technical support plan.
International customers who purchase products from distributors receive first
line technical support from their respective local distributor. A technical
support staff of engineers, located in the Company's United Kingdom sales and
marketing office, is available to support the distributors as well as the
Company's direct customers in the United Kingdom.


Manufacturing and Distribution

The Company utilizes several third party vendors to manufacture and distribute
its products. This permits the Company to manage peak volumes customary in the
software industry and to avoid having to maintain high fixed costs while
experiencing daily fluctuations in order and customer contacts.
The Company's practice is to ship its products promptly upon receipt of orders
from its customers and, as a result, product backlog is not significant.

Technical Calculation Software Products

The Company subcontracts with a single independent third party vendor, located
in Wilmington, Massachusetts, to manufacture all of its technical calculation
software products and fulfill all of its domestic orders.

With the exception of Mathcad upgrade orders generated by direct mail, the
Company processes all domestic orders from its leased facilities located in
Cambridge, Massachusetts. MathSoft subcontracts the processing of all Mathcad
upgrade direct mail orders with an independent service company located in
Chicago, Illinois.

All international orders are processed by a third party vendor located in the
United Kingdom that also provides warehousing and fulfillment services.
Data Analysis Software Products

The Company subcontracts with a third party vendor, located in Monroe,
Washington, to manufacture all of its S-PLUS product line updates. The Company
warehouses inventory and processes and fulfills domestic orders internally out
of its Seattle office. All international orders are processed and fulfilled by
third party vendors located in the United Kingdom that also provide warehousing
and fulfillment services.

Product Development
MathSoft's research and development organization, divided between the Company's
Cambridge, Massachusetts and Seattle, Washington locations, is responsible for
software development, product documentation, and quality assurance. Its
priorities are to continue technical innovation for power and performance and to
respond to market feedback by continuing to design products for ease-of-use.

MathSoft's development team consists of experts in software engineering, quality
assurance, mathematics, statistics, engineering and documentation. In software
engineering, MathSoft's professional staff has expertise in computer graphics,
compiler design, user interface design and advanced Windows and Internet
technologies.

During the fiscal year ended December 31, 1998, the Transition Period, and the
fiscal years ended June 30, 1997, and 1996, research and development costs
charged to operations were $4,964,000, $2,816,000, $5,143,000 and $3,659,000,
respectively. The Company did not capitalize any software research and
development costs during the twelve months ended December 31, 1998 as software
research and development costs incurred from technological feasibility to
general release were not material.









Competition

The markets for technical calculation and data analysis software products are
highly competitive. In the technical calculation software market, MathSoft
considers its principal competition to include technical calculation software
from companies providing specialized tools, such as The MathWorks, Waterloo
Maple Software and Wolfram Research. In the data analysis market, the Company
considers its principal competition to include statistical software products
from such companies as SAS and SPSS. In both markets, the Company faces
competition from companies providing competing software solutions, such as
spreadsheets. The Company may also face new competition from potential entrants
into the technical calculation and data analysis software markets, as well as
more focused competition from companies in related markets. For example,
providers of spreadsheet programs could add to or improve the technical
calculation and data analysis functionality of their existing products. Some of
these companies may have significant name recognition, as well as substantially
greater capital resources, marketing experience, research and development
staffs, and production facilities than the Company. Although the Company
believes it has certain technological advantages over existing competitors in
the technical calculation and the data analysis software markets, maintaining
these advantages will require continued investment by the Company in research
and development. There can be no assurance that the Company will have
sufficient resources to make such investment or that the Company will be able to
make the technological advances necessary to maintain its competitive position.

Intellectual Property Rights and Licenses

MathSoft's software is proprietary and the Company attempts to protect it with
copyrights, trade secret laws and internal nondisclosure safeguards, as well as
restrictions on copying, disclosure and transferability that are incorporated
into its software license agreements. Generally, the Company's products are not
physically copy-protected. In order to retain exclusive ownership rights to all
software developed by MathSoft, the Company licenses all software and provides
it in executable code only, with contractual restrictions on copying, disclosure
and transferability. As is customary in the industry, MathSoft licenses its
products to end-users by use of a 'shrink-wrap' license. The source code for all
of the Company's products is protected as a trade secret and as unpublished
copyrighted work. In addition, the Company has entered into nondisclosure and
inventions agreements with key employees. The Company has been granted two
patents and is aggressively pursuing patent protection. However, in those areas
where the Company has no patent protection, judicial enforcement of copyright
laws may be uncertain.

In fiscal 1994, the Company was granted a non-exclusive worldwide perpetual
license to Maple V Symbolic Algebra Software for inclusion in Mathcad and other
products in exchange for a fixed royalty payment.

The Company is a worldwide licensee until February 18, 2002 of Lucent
Technologies Inc. for the "S" programming language. Under the license, the
Company has the right to use, sublicense and support the "S" programming
language from Lucent Technologies in exchange for royalties. Any modifications,
enhancements, adaptations or derivations of the "S" programming language are the
property of the Company. After February 18, 2002, the Company, at its election,
may extend this license for five-year terms in perpetuity, provided that the
Company continues to comply with its obligations under the license. Although
termination of this license could have a material adverse effect on the
Company's operations because Lucent Technologies is the sole licensor of the "S"
programming language, the Company is not presently aware of any circumstances
which would prevent it from fulfilling its obligations under the license.

Due to the rapid pace of technological change in the software industry, the
Company believes that patent, trade secret and copyright protection are less
significant to its competitive position than factors such as the knowledge,
ability and experience of the Company's personnel, new product development,
frequent product enhancements, name recognition, and ongoing reliable product
maintenance and support.

The Company believes that its products and other proprietary rights do not
infringe the proprietary rights of third parties. There can be no assurance,
however, that third parties will not assert infringement claims in the future.

Employees

As of December 31, 1998, the Company employed approximately 174 regular
full-time and part-time employees, of which 17 were outside the United States.
As necessary, the Company supplements its regular employees with temporary and
contract personnel. As of December 31, 1998, the Company employed 12 temporary
and contract personnel, of which none were outside the United States. None of
the Company's regular employees are represented by a labor union or are subject
to a collective bargaining agreement. The Company has never experienced a work
stoppage and believes that its employee relations are good.











Cautionary Statements

In addition to the other information in this report, the following cautionary
statements should be considered carefully in evaluating the Company and its
business. Information provided by the Company from time to time may contain
certain "forward-looking" information, as that term is defined by (i) the
Private Securities Litigation Reform Act of 1995 (the "Act") and (ii) in
releases made by the Securities and Exchange Commission (the "SEC"). These
cautionary statements are being made pursuant to the provisions of the Act and
with the intention of obtaining the benefits of the "safe harbor" provisions of
the Act.

Variability of Quarterly Operating Results. The Company's quarterly operating
results may vary significantly from quarter to quarter, depending upon factors
such as the introduction and market acceptance of new products and new versions
of existing products, the ability to reduce expenses, and the activities of
competitors. Because a high percentage of the Company's expenses are relatively
fixed in the near term, minor variations in the timing of orders and shipments
can cause significant variations in quarterly operating results. The Company
operates with little or no backlog and has no long-term contracts.

Substantially all of its product revenues in each quarter result from software
licenses issued in that quarter making the Company's ability to accurately
forecast future revenues and income for any period necessarily limited. Any
forward-looking information provided from time to time by the Company represents
only management's then-best current estimate of future results or trends, and
actual results may differ materially from those contained in the Company's
estimates.

Potential Volatility of Stock Price. There has been significant volatility in
the market price of securities of technology companies. The Company believes
factors such as announcements of new products by the Company or its competitors,
quarterly fluctuations in the Company's financial results or other software
companies' financial results, shortfalls in the Company's actual financial
results compared to results previously forecasted by stock market analysts, and
general conditions in the software industry and conditions in the financial
markets could cause the market price of the Common Stock to fluctuate
substantially. These market fluctuations may adversely affect the price of the
Company's Common Stock.

Risks Associated with Acquisitions. The Company has made a number of
acquisitions and will continue to review future acquisition opportunities. No
assurances can be given that acquisition candidates will continue to be
available on terms and conditions acceptable to the Company. Acquisitions
involve numerous risks, including, among other things, possible dilution to
existing shareholders, difficulties and expenses incurred in connection with the
acquisitions and the subsequent assimilation of the operations and services or
products of the acquired companies, the difficulty of operating new (albeit
related) businesses, the diversion of management's attention from other business
concerns and the potential loss of key employees of the acquired company. In
the event that the operations of an acquired business do not live up to
expectations, the Company may be required to restructure the acquired business
or write-off the value of some or all of the assets of the acquired business.
There can be no assurance that any acquisition will be successfully integrated
into the Company's operations.



Risks Associated with Divestitures. The Company's product offerings presently
may be divided between two principal product families - those related to its
Mathcad line addressing the calculation needs of the technical, professional and
education markets, and those related to its S-PLUS offerings, marketed primarily
to professionals needing statistical analysis tools.

In setting strategic goals to maximize shareholder value, the Company from time
to time considers the options of divesting itself of one product family or the
other, or product lines within a given family, to concentrate its focus on the
business opportunity associated with the remaining product family or product
lines.

At the present time, the Company is not party to any agreement relating to the
sale of either of its product families or product lines within such families,
but it may elect to pursue such options at any time. If the Company were to
consummate such a sale, there can be no assurance that it would receive returns
from such sale that investors in the Company would consider attractive.

Risks Associated with Distribution Channels. The Company markets and
distributes its S-PLUS products in the U.S. through the Company's telesales and
outside sales force and internationally through third party resellers and
distributors and its own salesforce. Mathcad products are currently marketed
and distributed in the U.S. through third party resellers and distributors,
telesales and direct mail and electronic methods. Internationally, the
Company's Mathcad products are marketed and distributed through third party
resellers and distributors. There can be no assurance that the Company will be
able to retain its current resellers and distributors, or expand its
distribution channels by entering into arrangements with new resellers and
distributors in the Company's current markets or in new markets.





Risks Associated with International Operations. Sales outside North America
accounted for approximately 33% and approximately 34% of the Company's total
revenues in the fiscal years ended June 30, 1996 and 1997, approximately 30% of
the Company's total revenues during the Transition Period, and approximately 28%
of the Company's total revenues in the fiscal year ended December 31, 1998, and
may continue to represent a significant portion of the Company's product
revenues. Any decrease in sales outside North America may have a materially
adverse effect on the Company's operating results. The Company's international
business and financial performance may be affected by fluctuations in exchange
rates and by trade regulations.

Reliance on Third Party Licensors. Maple V, a software product licensed as a
part of Mathcad, contains certain copyrighted texts licensed from third party
publishers incorporated in the Company's Electronic Books, and the S programming
language, the language on which all of the StatSci's products are based, are
currently licensed from a single source or limited source suppliers. If such
licenses are discontinued, there can be no assurance that the Company will be
able to independently develop substitutes or to obtain alternative sources or,
if able to be developed or obtained as needed in the future, that such efforts
would not result in delays or reductions in product shipments or cost increases
that could have a material adverse effect on the Company's consolidated business
operations.

Rapid Technological Change; Competition. The technical calculation software
market is subject to rapid and substantial technological change, similar to that
affecting the software industry generally. The Company, to remain successful,
must be responsive to new developments in hardware and chip technology,
operating systems, programming technology, Internet technology and multimedia
capabilities. In addition, the Company competes against numerous other
companies, some of which have significant name recognition, as well as
substantially greater capital resources, marketing experience, research and
development staffs and production facilities than the Company. The Company's
financial results may be negatively impacted by the failure of new or existing
products to be favorably received by retailers and consumers due to price,
availability, features, other product choices or the necessity of promotions to
increase sales of the Company's products.


Year 2000 Issues. The Year 2000 issue exists because many computer systems and
applications currently use two-digit date fields to designate a year. As the
century date change occurs, date-sensitive systems will recognize the year 2000
as 1900, or not at all. This inability to recognize or properly treat the Year
2000 may cause systems to process critical financial and operational information
incorrectly. The Company utilizes software from third parties and related
technologies throughout its business that will be affected by the date change in
the year 2000. An internal study is currently under way to determine the full
scope and related costs to insure that the Company's systems continue to meet
its needs. The Company began incurring expenses in 1997 to resolve this issue.

Uncertainties Regarding Protection of Proprietary Technology; Uncertainties
Regarding Patents. The Company believes that while the mathematical
calculations performed by the Company's software are not proprietary, the speed
and quality of displaying the computation and the ease of use are unique to
MathSoft's products. The Company's success will depend, in part, on its ability
to protect the proprietary aspects of its products. The Company seeks to
protect these proprietary aspects of its products principally through a
combination of contract provisions and copyright, patent, trademark and trade
secret laws. There can be no assurance that the steps taken by the Company to
protect its proprietary rights will be adequate to prevent misappropriation of
its technology. Although the Company believes that its products and technology
do not infringe any existing proprietary rights of others, the use of patents to
protect software has increased and there may be pending or issued patents of
which the Company is not aware that the Company may need to license or challenge
at significant expense. There can be no assurance that any such license would
be available on acceptable terms, if at all, or that the Company would prevail
in any such challenge.

Reliance on Attracting and Retaining Key Employees. The Company's continued
success will depend in large part on its ability to attract and retain highly
qualified technical, managerial, sales and marketing and other personnel.
Competition for such personnel is intense. The Company has non-competition
agreements with its key management and technical personnel. There can be no
assurance that the Company will be able to continue to attract or retain such
personnel.

Risks Associated with New Products or Services. The Company's future revenue
growth rate and earnings performance depend on a number of factors, including
the continued success of its existing products and service offerings and the
development of one or more new products or services. These investments may
adversely affect the Company's quarterly and annual financial results until such
time that they begin to return a profit. Furthermore, there can be no assurance
that these investments will ever achieve the desired financial results.










ITEM 2. PROPERTIES.

The Company leases 34,562 square feet of office space at 101 Main Street,
Cambridge, Massachusetts of which 23,350 square feet is occupied by the Company
and 11,212 square feet is sublet to a third party. The Company renewed its
lease for the 23,350 square feet it currently occupies on November 30, 1998 and
this lease is scheduled to terminate in October 2004. A third party vendor
provides warehousing services to meet the Company's needs. The Company also
leases 15,891 square feet of office space and subleases 7,043 square feet of
office space at 1700 Westlake Avenue North, Seattle, Washington. This lease
expires in September 1999 and the sublease expires in March 2000. In connection
with the acquisition of acroScience, the Company assumed a lease on 1,740 square
feet of office space in Boulder, Colorado, which is scheduled to terminate in
January 2000. The Company currently sublets this space to a third party on a
renewable 90 day basis, the term of which will terminate in March 1999. The
Company also leases 2,931 square feet of office space in the United Kingdom.
The term of the lease for this office space is scheduled to expire in March
2000.

The Company believes that its facilities are adequate for its needs. The Company
does not consider the specific location of its offices to be material to its
business.



ITEM 3. LEGAL PROCEEDINGS.

The Company is not involved in any legal proceedings which could have a material
adverse effect on the Company.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY-HOLDERS.

Not applicable.

(1) The Company changed its fiscal year from June 30 to December 31. The Transition Period represents the six month
period from July 1, 1997 - December 31, 1997.





Fiscal Year Ended December 31, 1998 Compared to the Twelve Months Ended December
31, 1997 (unaudited)

Total revenues increased 15.2% from $21,224,000 for the twelve months ended
December 31, 1997 to $24,447,000 for the fiscal year ended December 31, 1998.
The increase in total revenues was primarily attributable to worldwide new
license and upgrade revenue generated by the Company's Mathcad product line, as
well as new license and service revenue generated from the S-PLUS product line.

Worldwide Mathcad product line revenues increased 11.9% from $13,947,000 in the
twelve months ended December 31, 1997 to $15,606,000 during the twelve months
ended December 31, 1998, but decreased as a percentage of total revenues from
65.7% to 63.8% for the twelve months ended December 31, 1997 and 1998,
respectively. The increase in Mathcad product line revenue is due primarily to
the release of Mathcad 8 (released in September 1998) and Mathcad 7 (released in
June 1997). To a lesser extent, this increase is also due to the release of
StudyWorks II in March 1998. Worldwide S-PLUS license and service revenue
increased 21.5% from $7,277,000 in the twelve months ended December 31, 1997 to
$8,841,000 during the twelve months ended December 31, 1998, and increased as a
percentage of total revenues from 34.3% to 36.2%, respectively. The increase in
S-PLUS product line revenue is primarily attributable to the release of S-PLUS
4.5 (released in May 1998) and S-PLUS 4.0 (released in September 1997). Total
international revenues, attributable to all product lines, increased 3.2% from
$6,682,000 in 1997 to $6,897,000 in 1998, and decreased as a percentage of total
revenues from 31.5% to 28.2%, respectively.

Total cost of revenues decreased 5.3% from $4,482,000 for the twelve months
ended December 31, 1997 to $4,246,000 during the twelve months ended December
31, 1998, and decreased as a percentage of total revenues from 21.1% to 17.4%,
respectively. The decrease in total cost of revenues as a percentage of total
revenues was primarily attributable to switching from disk to CD media with the
release of Mathcad 7 for Windows, thereby decreasing direct material costs on a
per unit basis.

Sales and marketing expenses for the twelve-months ended December 31, 1997 were
$10,413,000 and remained relatively consistent as compared to $10,364,000 for
the fiscal year ended December 31, 1998, and decreased as a percentage of total
revenues from 49.1% to 42.4%, respectively.

Research and development expenses decreased 11.1% from $5,581,000 for the twelve
months ended December 31, 1997 to $4,964,000 during the fiscal year ended
December 31, 1998, and decreased as a percentage of total revenues from 26.3% to
20.3%, respectively. The decrease in research and development expenses was
primarily attributable to a decrease in consulting costs associated with
development initiatives in the Company's Data Analysis Products Division and an
increase in research contribution.

General and administrative expenses decreased 6.7% from $2,909,000 for the
twelve months ended December 31, 1997 to $2,713,000 during the fiscal year ended
December 31, 1998, and decreased as a percentage of total revenues from 13.7% to
11.1%, respectively. The decrease in overall general and administrative
expenses was primarily attributable to decreases in foreign currency transaction
losses.

Net income for the fiscal year ended December 31, 1998 was $2,220,000 compared
to a net loss of $2,129,000 for the twelve months ended December 31, 1997.
Improved performance from the recently refreshed Mathcad and S-PLUS product
line, coupled with margin improvements and management control of operating
expenses contributed to this improvement in profit.



Fiscal Year Ended December 31, 1998 Compared to Fiscal Year Ended June 30, 1997

Total revenues increased 38.3% from $17,678,000 for the twelve months ended June
30, 1997 to $24,447,000 for the fiscal year ended December 31, 1998. This
increase in total revenues was primarily attributable to worldwide new license
and upgrade revenue generated by the Mathcad product line as well as new license
and service revenue generated from the S-PLUS product line.

Worldwide Mathcad product line sales increased 31.7% from $11,850,000 in the
twelve months ended June 30, 1997 to $15,606,000 during the fiscal year ended
December 31, 1998, but decreased as a percentage of total revenues from 67.0% to
63.8%, respectively. The twelve months ended December 31, 1998 had increased
revenue associated with Mathcad 8 (released in September 1998) and Mathcad 7
(released in June 1997). Worldwide S-PLUS product line revenue increased 51.7%
from $5,828,000 in the twelve months ended June 30, 1997 to $8,841,000 during
the fiscal year ended December 31, 1998, and increased as a percentage of total
revenues from 33.0% to 36.2%, respectively. S-PLUS product line had increased
license and services revenue in the fiscal year ended December 31, 1998 due to
the release of S-PLUS 4.5 (released in May 1998) and S-PLUS 4.0 (released in
September 1997). Total international revenues, attributable to all product
lines, increased 14.6% from $6,017,000 in 1997 to $6,897,000 in 1998, and
decreased as a percentage of total revenues from 34.0% to 28.2%, respectively.

Total cost of revenues increased 7.6% from $3,946,000 for the twelve months
ended June 30, 1997 to $4,246,000 during the fiscal year ended December 31,
1998, and decreased as a percentage of total revenues from 22.3% to 17.4%,
respectively. The decrease in total cost of revenues as a percentage of total
revenues was primarily attributable to switching from disk to CD media with the
release of Mathcad 7 for Windows, thereby decreasing direct material costs on a
per unit basis.

Sales and marketing expenses for the twelve-months ended June 30, 1997 were
$10,251,000 and remained relatively consistent compared to $10,364,000 for the
fiscal year ended December 31, 1998, but decreased as a percentage of total
revenues from 58.0% to 42.4%, respectively.

Research and development expenses decreased 3.5% from $5,143,000 for the twelve
months ended June 30, 1997 to $4,964,000 during the fiscal year ended December
31, 1998, and decreased as a percentage of total revenues from 29.1% to 20.3%.
The decrease in research and development expenses was primarily attributable to
a decrease in consulting costs associated with development initiatives in the
Company's Data Analysis Products Division and an increase in research
contribution.

General and administrative expenses for the fiscal year ended June 30, 1997 were
$2,732,000 and remained consistent at $2,713,000 during the twelve months ended
December 31, 1998, and decreased as a percentage of total revenues from 15.5% to
11.1%, respectively. The consistency in expenditures and reduction as a
percentage of total revenues was due to management efforts to control costs.

Net income for the fiscal year ended December 31, 1998 was $2,220,000 compared
to net loss of $4,300,000 for the twelve months ended June 30, 1997. Improved
performance from the recently refreshed Mathcad and S-PLUS product lines coupled
with margin improvements contributed to this increase in profit.










Transition Period Ended December 31, 1997 Compared to the Six-Month Period Ended
December 31, 1996 (unaudited)

Total revenues increased 37.4% from $9,478,000 for the six months ended December
31, 1996 to $13,024,000 during the Transition Period. This increase in total
revenues was primarily attributable to upgrade revenue generated by the release
of Mathcad 7 for Windows in June 1997, new license revenue generated from S-PLUS
4.0 released in September 1997, and to a lesser extent, S-PLUS service revenue.

Mathcad for Windows generated upgrade revenue of $680,000 during the six months
ended December 31, 1996 compared to upgrade revenue of $2,677,000 during the
Transition Period, an increase as a percentage of total revenues from 7.2% to
20.6%, respectively. Prior to the release of Mathcad 7 for Windows in June
1997, the Company's last significant upgrade, Mathcad 6.0 for Windows, was
released approximately twenty-three months earlier in July 1995 and therefore
upgrade revenue was much lower in the six months ended December 31, 1996.
Worldwide S-PLUS product line revenue increased 39.4% from $2,531,000 for the
six months ended December 31, 1996 to $3,529,000 during the Transition Period,
and increased as a percentage of total revenues from 26.7% to 27.1%,
respectively. Worldwide S-PLUS service revenue increased 167.7% from $269,000
in the six months ended December 31, 1996 to $720,000 during the Transition
Period, and increased as a percentage of total revenues from 2.8% to 5.5%,
respectively. Total international revenues, attributable to all product lines,
increased 20.9% from $3,182,000 in 1996 to $3,846,000 during the Transition
Period, and decreased as a percentage of total revenues from 33.6% to 29.5%,
respectively.

Total cost of revenues for the six-month period increased 27.0% from $1,983,000
for the six months ended December 31, 1996 to $2,519,000 during the Transition
Period, and decreased as a percentage of total revenues from 20.9% to 19.3%,
respectively. The decrease in total cost of revenues as a percentage of total
revenues was primarily attributable to switching from disk to CD media with the
release of Mathcad 7 for Windows, thereby decreasing direct material costs on a
per unit basis. To a lesser degree, fixed costs, such as licensing costs for
the "S" language used in the S-PLUS product line and the amortization of
purchased technology, decreased as a percentage of total revenues due to an
overall higher revenue base during the Transition Period. Such decreases were
partially offset by an increase in the inventory provision to adequately cover
excess inventory exposure and an increase in cost of services from $404,000 for
the six months ended December 31, 1996 to $702,000 during the Transition Period
consistent with the increase in service revenue.

Sales and marketing expenses increased 3.2% from $5,007,000 for the six months
ended December 31, 1996 to $5,169,000 during the Transition Period, and
decreased as a percentage of total revenues from 52.8% to 39.7%, respectively.
The increase in sales and marketing expenses was primarily attributable to
expenses incurred related to the launch of Mathcad 7 for Windows and S-PLUS 4.0,
as well as an increase in S-PLUS domestic sales expenses incurred to support
direct sales of this expanding product line.

Research and development expenses increased 18.4% from $2,378,000 for the six
months ended December 31, 1996 to $2,816,000 during the Transition Period, and
decreased as a percentage of total revenues from 25.1% to 21.6%. The increase
in overall research and development expenses was primarily attributable to
expenses related to development initiatives in the Company's Data Analysis
Products Division and additional personnel to support such initiatives, as well
as an increase in international product translation costs for Mathcad 7 French,
German and Japanese.



General and administrative expenses increased 14.3% from $1,241,000 for the six
months ended December 31, 1996 to $1,418,000 during the Transition Period and
decreased as a percentage of total revenues from 13.1% to 10.9%, respectively.
The increase in general and administrative expenses was primarily attributable
to costs incurred for management incentive compensation provisions based
primarily on the achievement of profitability targets, and to a lesser extent,
to fluctuations in international exchange rate transactions.

Net income for the Transition Period was $1,105,000 compared to net loss of
$1,066,000 for the six months ended December 31, 1996. Improved performance
from the refreshed Mathcad and S-PLUS product lines coupled with margin
improvements all contributed to this improvement in profit.

Fiscal Year Ended June 30, 1997 Compared to Fiscal Year Ended June 30, 1996

Total revenues decreased 14.9% from $20,767,000 for the fiscal year ended June
30, 1996 ("Fiscal 1996") to $17,678,000 for the fiscal year ended June 30, 1997
("Fiscal 1997"). The decrease in total revenues was primarily attributable to a
worldwide decrease in both new license and upgrade revenue generated by the
Company's core product, Mathcad for Windows, and to a lesser extent, a decrease
in sales of Electronic Books, which work with Mathcad, and a decrease in S-PLUS
product line and services revenue. The decrease in total revenues was partially
offset by revenue generated by the release of Mathcad 6.0 for Macintosh in
November 1996, revenue generated by the StudyWorks! product line released in
June 1996 and revenue generated from the Axum product line acquired in the
second quarter of Fiscal 1996.





Mathcad for Windows generated upgrade revenue of $4,287,000 in Fiscal 1996
compared to upgrade revenue of $1,388,000 in Fiscal 1997, a decrease as a
percentage of total revenues from 20.6% to 7.9%, respectively. Prior to the
release of Mathcad 7 for Windows in June 1997, the Company's last significant
upgrade, Mathcad 6.0 for Windows, was released approximately twenty-three months
earlier during the fiscal year ended June 30, 1995, and its upgrade cycle
therefore came to a close in Fiscal 1997. Worldwide Mathcad for Windows
non-upgrade revenue decreased 13.8% from $7,377,000 in Fiscal 1996 to $6,359,000
in Fiscal 1997 due primarily to the Company's distribution channel's
anticipation of the delivery of the next major release of Mathcad for Windows,
Mathcad 7 for Windows, and decreasing sell-through of the older Mathcad 6.0 for
Windows release. Worldwide S-PLUS product line and services revenue decreased
8.7% from $5,904,000 in Fiscal 1996 to $5,389,000 in Fiscal 1997, and increased
as a percentage of total revenues from 28.4% to 30.5%, respectively. The
decrease in S-PLUS product line and services revenue was attributable to a
reduction in license revenue, due to a material shift from UNIX license sales to
lower priced Windows license sales, and to the discontinuance of unprofitable
S-PLUS services revenue. Moreover, the product line reached its fourth year of
life without a major new release, resulting in sluggish new license sales prior
to the delivery of S-PLUS 4.0 in September 1997. Revenues attributable to the
Axum product line acquired in the TriMetrix, Inc. acquisition accounted for
$676,000, or 3.3% of total revenues, in Fiscal 1996 compared to $1,023,000, or
5.8% of total revenues, in Fiscal 1997. Total international revenues
attributable to sales of all Company product lines decreased 10.9% from
$6,756,000 in Fiscal 1996 to $6,018,000 in Fiscal 1997, and increased as a
percentage of total revenues from 32.5% to 34.0%, respectively.



Total cost of revenues decreased 1.4% from $4,000,000 in Fiscal 1996 to
$3,946,000 in Fiscal 1997, and increased as a percentage of total revenues from
19.3% to 22.3%, respectively. The increase in total cost of revenues as a
percentage of total revenues was primarily attributable to a reduction of
inventory reserves in Fiscal 1996 based on an evaluation of actual inventory
exposure and reserve requirements. In contrast, the Company increased inventory
reserves in Fiscal 1997 to adequately cover inventory exposure in the sales
distribution channel as the Company prepared to release its next major upgrade
of Mathcad, Mathcad 7 for Windows. In addition, fixed licensing costs for the
"S" language used in the S-PLUS product line increased in Fiscal 1997 per terms
of the license agreement and other fixed costs, such as the amortization of
purchased technology, increased as a percentage of total revenues by
approximately 1.5% due to an overall lower revenue base in Fiscal 1997.

Sales and marketing expenses increased 5.5% from $9,719,000 in Fiscal 1996 to
$10,251,000 in Fiscal 1997, and increased as a percentage of total revenues from
46.8% to 58.0%, respectively. The increase in overall sales and marketing
expenses was attributable to marketing expenses incurred related to the Fiscal
1997 launch of the StudyWorks! product line, Mathcad 6.0 for Macintosh and, most
recently, Mathcad 7 for Windows, as well as to an increase in S-PLUS domestic
sales expenses as the Company reorganized its sales infrastructure to support
direct sales into this expanding product line. International sales and
marketing expenses increased 3.8% from $2,285,000 in Fiscal 1996 to $2,372,000
in Fiscal 1997.

Research and development expenses increased 40.6% from $3,659,000 in Fiscal 1996
to $5,143,000 in Fiscal 1997, and increased as a percentage of total revenues
from 17.6% to 29.1%. The increase in overall research and development expenses
was primarily attributable to increased personnel and consulting costs
associated with the continued expansion and development of the S-PLUS product
line, specifically related to the first release of StatServer in April 1997 and
the impending release of S-PLUS 4.0 in September 1997.

General and administrative expenses increased 11.3% from $2,455,000 in Fiscal
1996 to $2,732,000 in Fiscal 1997 and increased as a percentage of total
revenues from 11.8% to 15.5%, respectively. The increase in overall general and
administrative expenses was primarily attributable to fluctuations in
international exchange rate transactions. The Company recorded exchange rate
losses of $12,000 in Fiscal 1996 compared to exchange rate losses of $257,000 in
Fiscal 1997.

Net loss for Fiscal 1997 was $4,300,000 compared to net income of $1,076,000 in
Fiscal 1996. Fiscal 1997 reflected a year of investment for the Company as
evidenced by its commitment to strategic development initiatives, most notably
in the Company's Data Analysis Products Division. The release of new products
with new product cycles will support renewed growth in both the Mathcad and
S-PLUS product lines.



Liquidity and Capital Resources

Cash and cash equivalents, totaling $5,707,000 at December 31, 1998, increased
$1,573,000 during the fiscal year ended December 31, 1998, from $4,134,000 at
December 31, 1997. The positive cash flow resulted primarily from cash provided
by operating activities of $2,163,000 and proceeds from the exercise of stock
options of $369,000 which were offset by purchases of property, equipment and
other assets of $1,098,000.





The Company generated $2,163,000 in cash from operating activities during the
fiscal year ended December 31, 1998. The cash generated by operating activities
was primarily attributable to net income of approximately $2,220,000, non-cash
depreciation and amortization charges, and an increase in deferred revenue,
offset by an increase in accounts receivable. Accounts receivable and deferred
revenue increased primarily due to the growth in the Company's business. The
Company used $1,098,000 in investing activities primarily due to the purchase of
$624,000 of property and equipment, and the purchase of certain intangible
assets for $382,000. Proceeds generated from capital lease obligations and
equipment financing and the exercise of stock options of $815,000 and $369,000,
respectively, were offset by payments on capital lease obligations and equipment
financing of $641,000.

The Company's financial reserves are represented by cash and cash equivalents as
of December 31, 1998. The Company has a line of credit agreement with a
commercial bank. Borrowings under the line are limited to the lesser of 65% of
eligible domestic accounts or $1,000,000 based on certain profitability
covenants. Borrowings are secured by substantially all of the Company's assets
and bear interest at the bank's prime rate plus 1%. The line of credit contains
certain restrictive covenants, including minimum amounts of profitability,
equity, leverage and liquidity, all as defined in the agreement. There were no
amounts outstanding under this line at December 31, 1998. This line was
renewed on February 24, 1999 and now expires on April 30, 2000. Borrowings
under this renewed line are limited to the lesser of 80% of eligible domestic
accounts or $2,000,000 based on certain profitability covenants. Borrowings are
secured by substantially all of the Company's assets and bear interest at the
bank's prime rate plus 0.5%.

The Company believes its financial reserves and cash flows from future
operations will be sufficient to meet its liquidity requirements for at least
the next twelve months. The foregoing statement is forward-looking and involves
risks and uncertainties, many of which are outside the Company's control. The
Company's actual experience may differ materially from that discussed above.
Factors that might cause such a difference include, but are not limited to,
those discussed in "Cautionary Statements" in this Form 10-K for the fiscal year
ended December 31, 1998 as well as future events that have the effect of
reducing the Company's available cash balances, such as unanticipated operating
losses or capital expenditures, cash expenditures related to possible future
acquisitions, or investment in new products or services. The Company may be
presented from time to time with acquisition opportunities that require
additional external financing, and the Company may from time to time seek to
obtain additional funds from public or private issuance of equity or debt
securities. There can be no assurance that any such financing will be available
at all or on terms favorable to the Company.




Year 2000 Readiness Disclosure Statement


Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish 21st century dates from
20th century dates. As a result, many companies' software and computer systems
may need to be upgraded or replaced in order to comply with such "Year 2000"
requirements. MathSoft is in the process of evaluating and correcting the Year
2000 compliance of its proprietary products and services and third party
equipment and software that it uses, as well as its non-information technology
systems, such as building security, voice mail and other systems.

The Company's Year 2000 compliance efforts consist of the following phases: (i)
identification of all software products, information technology systems and
non-information technology systems; (ii) assessment of repair or replacement
requirements; (iii) repair or replacement; (iv) testing; (v) implementation; and
(vi) creation of contingency plans in the event of Year 2000 failures. The
Company has completed phase (i) and has substantially completed phase (ii).
The Company expects to substantially complete phase(iii) by June 1999 and phases
(iv), (v) and (vi) of its Year 2000 compliance efforts by September 1999.

To date, the Company has not incurred any material expenditure in connection
with identifying or evaluating Year 2000 compliance issues. Preliminary
estimates regarding expected costs to MathSoft for evaluating and correcting
Year 2000 issues are in the range of $450,000 to $850,000, but there can be no
assurance that the costs will not exceed such amounts. The Company's
expectations regarding Year 2000 remediation efforts will evolve as it continues
to analyze and correct its systems. The Company has not yet developed a formal
Year 2000-specific contingency plan. The Company expects that a formal Year
2000 contingency plan will evolve as it completes its Year 2000 compliance
efforts. Failure by the Company to resolve Year 2000 issues with respect to its
products and services could have a material adverse effect on the Company's
business, results of operation and financial condition. Furthermore, failure of
third-party equipment or software to operate properly with regards to the year
2000 and thereafter could require MathSoft to incur significant unanticipated
expenses to remedy any problems.

Report of Independent Public Accountants



To MathSoft, Inc.:

We have audited the accompanying consolidated balance sheets of MathSoft, Inc.
(a Massachusetts corporation) and subsidiaries as of December 31, 1998 and 1997,
and the related consolidated statements of operations, stockholders' equity and
cash flows for the year ended December 31, 1998, the six-month period ended
December 31, 1997 and each of the two years in the period ended June 30, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of MathSoft, Inc. and subsidiaries
as of December 31, 1998 and 1997, and the results of their operations and their
cash flows for the year ended December 31, 1998, the six-month period ended
December 31, 1997, and for each of the two years in the period ended June 30,
1997, in conformity with generally accepted accounting principles.

MATHSOFT, INC. AND SUBSIDIARIES

Notes to Consolidated Financial Statements
December 31, 1998

(Including Data Applicable to Unaudited Period)


(1) Operations and Significant Accounting Policies

MathSoft, Inc. (MathSoft) was incorporated on October 12, 1984. MathSoft
develops, markets and supports software productivity tools for the technical
calculation and data analysis markets comprised of professionals, students and
educators.

The accompanying consolidated financial statements reflect the application of
certain accounting policies as described in this note and elsewhere in the
consolidated financial statements and notes.

The accompanying consolidated financial statements comprise those of MathSoft
and its wholly owned subsidiaries Statistical Sciences, Inc. (StatSci),
TriMetrix, Inc. and acroScience Corporation (collectively referred to as the
Company). All material intercompany accounts and transactions have been
eliminated in consolidation.

(a) Change In Fiscal Year

On December 16, 1997, the Company changed its fiscal year from June 30 to
December 31. Accordingly, the Company's transition period, which ended on
December 31, 1997, was the six-month period from July 1, 1997 to December 31,
1997. The unaudited consolidated statements of operations and cash flows for
the year ended December 31, 1997 are presented for comparative purposes only.
These unaudited statements, in the opinion of management, include all
adjustments (consisting only of normal and recurring adjustments) necessary for
fair presentation of results for the period.

(b) Revenue Recognition

The Company derives substantially all of its revenue from technical calculation
software products for use on desktop computers. Revenue from the licensing of
software products is recognized when the products are shipped, as there are no
significant postdelivery obligations, and the Company provides for estimated
returns and warranty costs at the time of sale. The Company offers maintenance
contracts and training on StatSci's products. Maintenance revenue is recognized
ratably over the term of the related contracts generally for one year or less.
Training revenue is recognized as services are performed. Amounts received in
advance for maintenance agreements are recorded as deferred revenue on the
accompanying consolidated balance sheets.

(c) Cash and Cash Equivalents

Cash and cash equivalents are stated at cost, which approximates market, and
consist of short-term, highly liquid investments with original maturities of
less than three months. Cash equivalents were approximately $4,000,000 and
$1,000,000 as of December 31, 1998 and 1997, respectively, and consisted
primarily of investments in commercial paper.


(d) Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market and
consist of the following:




DECEMBER 31, DECEMBER 31,
1998 1997

Raw materials. $ 98,200 $ 44,786
Finished goods 276,120 210,419
------------- -------------

$ 374,320 $ 255,205
============= =============




(e) Depreciation and Amortization

The Company provides for depreciation and amortization by charges to operations
on a straight-line basis, in amounts estimated to allocate the cost of the
assets over their estimated useful lives as follows:





ASSET CLASSIFICATION USEFUL LIVES

Computer equipment and software 3 years
Furniture and fixtures. . . . . 3-5 years
Leasehold improvements. . . . . Life of lease




Property and equipment under capital leases are amortized over the shorter of
the estimated useful life of three to five years or the term of the lease.

(f) Research and Development

The Company accounts for its software research and development costs in
accordance with Statement of Financial Accounting Standards (SFAS) No. 86,
Accounting for the Costs of Computer Software To Be Sold, Leased or Otherwise
Marketed. During the year ended December 31, 1998, the six-month period ended
December 31, 1997, and the years ended June 30, 1997 and 1996, the Company
expensed all research and development costs as those costs incurred from
technological feasibility to general release were not material.


(g) Net Income (Loss) Share

The Company reports earnings per share in accordance with SFAS No. 128, Earnings
per Share. Under SFAS No. 128, basic net income (loss) per common share is
computed based on net income (loss) available to common stockholders and the
weighted average number of common shares outstanding during the period. Diluted
net income (loss) per share is computed based on including the number of
additional common shares that would have been outstanding if the dilutive
potential common shares had been issued.

A reconciliation of basic and diluted shares outstanding is as follows:

(h) Postretirement Benefits

The Company has no obligation for postretirement benefits.



(i) Foreign Currency Translation

Assets and liabilities of the Company's foreign branch are translated to U.S.
dollars using the exchange rate at each balance sheet date. Income and expense
accounts are translated using an average rate of exchange during the period.
Foreign currency translation adjustments are accumulated as a separate component
of stockholders' equity. The effect of aggregate transaction gains and losses
are recognized currently in the statements of operations and were approximately
$20,000 and $277,000 in the years ended December 31, 1998 and December 31, 1997
(unaudited), respectively, $75,000 in the six-month period ended December 31,
1997, and approximately $(257,000) and $(12,000) in the years ended June 30,
1997 and 1996, respectively.

(j) Other Assets

Other assets are comprised primarily of purchased technology and intangible
assets. Purchased technology of $3,008,765 was fully amortized at December 31,
1998 and had accumulated amortization of $2,938,265 at December 31, 1997. Other
assets totaled $488,595 and $97,890, net of accumulated amortization of $98,415
and $7,715 as of December 31, 1998 and 1997, respectively. During 1998, the
Company purchased intangible assets for approximately $382,000 and this amount
is included in other assets and is being amortized over 36 months.

The Company assesses the realizability of its long-lived assets in accordance
with SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets To Be Disposed Of. Under SFAS No. 121, the Company is
required to assess the valuation of its long-lived assets, including intangible
assets, based on the estimated cash flows to be generated by such assets. Based
on its most recent analysis, the Company believes that no material impairment of
intangible assets exists as of December 31, 1998.


(k) Concentration of Credit Risk

SFAS No. 105, Disclosure of Information About Financial Instruments with
Off-Balance-Sheet Risk and Financial Instruments with Concentrations of Credit
Risk, requires disclosure of any significant off-balance-sheet and credit risk
concentrations. The Company's financial instruments that subject the Company to
credit risk consist primarily of cash and cash equivalents and accounts
receivable. The Company maintains the majority of its cash balances with one
financial institution. The Company has not experienced significant losses
related to accounts receivable from any individual customers or groups of
customers in any specific industry or geographic area.

During the year ended December 31, 1998 and the six-month period ended December
31, 1997, one customer accounted for 13% and 12% of net revenues, respectively.
One customer accounted for 14% and 12% of net revenues in the years ended June
30, 1997 and 1996, respectively. As of December 31, 1998 the Company had one
customer that accounted for 12% of accounts receivable. As of December 31,
1997, the Company had two customers that individually accounted for 17% and 11%
of accounts receivable.

(l) Use of Estimates and Uncertainities

The preparation of these consolidated 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 reported
period. Actual results could differ from those estimates.

The Company is subject to a number of risks and uncertainties similar to those
of other companies of the same size within its industry, including, without
limitation, rapid technological change, competition, and reliance on attracting
and retaining key employees.

(m) Financial Instruments

SFAS No. 107, Disclosures About Fair Value of Financial Instruments, requires
disclosure about fair value of financial instruments consisting of cash,
accounts receivable and capital leases. The estimated fair value of these
financial instruments approximates their carrying value in the accompanying
financial statements.

(n) New Accounting Standards

In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS No.
133, Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts
(collectively referred to as derivatives) and for hedging activities. SFAS No.
133 is effective for fiscal years beginning after June 15, 1999. The Company
does not expect the adoption of this statement to have a material impact on its
consolidated financial position or results of operations.


(2) Unaudited Comparative Results

The following unaudited financial information for the six-month period ended
December 31, 1996 is presented to provide comparative results for the transition

(3) Income Taxes

The Company accounts for income taxes in accordance with SFAS No. 109,
Accounting for Income Taxes. 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.


The components of domestic and foreign income (loss) before the provision for
income taxes are as follows:

============== ==============




Due to the uncertainty surrounding the realization of its deferred tax assets,
the Company has recorded a full valuation allowance against its deferred tax
assets.

At December 31, 1998, the Company has utilized approximately $3,855,000 of net
operating loss carryforwards and has available net operating loss carryforwards
of approximately $14,767,000 and tax credit carryforwards of approximately
$903,000. The net operating loss and tax credit carryforwards may be used to
offset future federal taxable income and federal income taxes, respectively,
through the year ending December 31, 2013. The Internal Revenue Code contains
provisions that limit the net operating loss and credit carryforwards available
to be used in any given year upon the occurrence of certain events, including
significant changes in ownership interests.

(4) Equipment Financing and Capital Leases

During 1998, the Company entered into several financing arrangements for the
purchase of fixed assets totaling $815,000, of which $511,929 were equipment
lease financing arrangements and the remaining were capital leases. All of the
financing arrangements are payable in 24 equal monthly payments of principal
plus interest ranging from 10.1% to 10.7%.



The Company leases certain equipment under capital leases expiring through
fiscal 2002. Future minimum payments as of December 31, 1998 under these leases
and financing arrangements are as follows:




Year ending December 31,
1999. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 522,851

==========================










(5) Commitments

In August 1993, the Company entered into a six-year operating lease for its
facility in Cambridge, Massachusetts. The lease provides for uneven payments
during the six-year period. However, rent expense is charged to operations
evenly over the leased period. On November 30, 1998, the Company renewed the
lease for a period of five years ending October 2004. The Company also has
operating leases for its Seattle and international office spaces and certain
office equipment.

The approximate future lease payments under the Company's operating lease
arrangements, exclusive of operating costs and net of sublease revenue through
October 2004, are as follows:





GROSS SUBLEASE NET

Total future lease payments $ 2,688,000 $(133,000) $2,555,000
========================= ========== ==========




Rental expense under the Company's operating leases was approximately $793,000
and $786,000 for the years ended December 31, 1998 and December 31, 1997
(unaudited), respectively, $430,000 for the six-month period ended December 31,
1997 and approximately $723,000 and $707,000 for the years ended June 30, 1997
and 1996, respectively.

(6) Stockholders' Equity

(a) Stock Option Plans

The Company has a stock option plan that was adopted in 1992 (the 1992 Plan)
whereby the Board of Directors may grant incentive stock options (ISOs),
nonqualified stock options, awards of common stock and authorizations to make
direct purchases of common stock to eligible employees and others, as defined.
ISOs are granted at a price not less than fair market value at the date of
grant. The options typically vest over a five-year period. At December 31,
1998 the Company had 101,379 options available for future grant under the 1992
Plan.

The Company has a Nonemployee Director Stock Option Plan (the 1992 Director's
Plan) pursuant to which directors who are not officers or employees of the
Company annually receive options to purchase shares of the Company's common
stock. A total of 160,000 shares of common stock may be issued under the 1992
Director's Plan. The exercise price of each option equals the fair market value
of the stock on the date of grant. The options are exercisable upon the earlier
of one year from the date of grant or the first annual meeting of stockholders,
following the date of grant at which members of the Board are elected.

The Board of Directors granted Key Officer Stock Options to members of senior
management of the Company in 1992. The Key Officer Stock Options are
nonqualified, nonplan stock options exercisable for an aggregate of 907,556
shares of common stock at an exercise price of $1.08 per share, the fair market
value of the common stock on the date of grant. Each such option expires 11
years from the date of grant, subject to earlier termination if the optionee
ceases to serve the Company other than by reason of death or disability. Each
Key Officer Stock Option became exercisable upon the closing of the Company's
initial public offering.

The Company has a Non-Qualified, Non-Officer Stock Option Plan (the 1996
Non-Officer Plan) under which employees and consultants to the Company are
granted nonqualified options to purchase stock in the Company. A total of
200,000 shares of common stock may be issued under the 1996 Non-Officer Plan.
The vesting of options granted under the 1996 Non-Officer Plan is determined at
the date of grant. Each option expires 10 years from the date of grant, subject
to earlier termination if the optionee ceases to serve the Company other than by
reason of death or disability, and is not transferable.


As of December 31, 1998, a total of 4,698,508 shares of common stock were
reserved for issuance under the Plans, the 1992 Director's Plan, the Key Officer
Stock Options, and the 1996 Non-Officer Plan.






The Company accounts for its stock-based compensation plans under Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employee, and
has adopted the disclosure-only alternative under SFAS No. 123 for employees,
which requires disclosure of the pro forma effects on earnings and earnings per
share as if SFAS No. 123 had been adopted, as well as certain other information.
The Company has computed the pro forma disclosures required under SFAS No. 123
for all stock options granted during fiscal years 1996, 1997 and 1998, and the
six months ended December 31, 1997, including the Employee Stock Purchase Plan
using the Black-Scholes option pricing model prescribed by SFAS No. 123. For
nonemployees, SFAS No. 123 requires that the compensation expense calculated
using the Black-Scholes option pricing model be charged to the statement of
operations. The value of options awarded to nonemployees as determined under
SFAS No. 123 is not material to the results of operations for both fiscal years
ended June 30, 1997 and 1996, or for the six-month period ended December 31,
1997. There were no grants to nonemployees for the year ended December 31,
1998.

The assumptions used and the weighted average information are as follows:






SIX-MONTH

The effect of applying SFAS No. 123 would be as follows:

Because the method prescribed by SFAS No. 123 has not been applied to options
granted prior to 1995, the resulting pro forma compensation cost may not be
representative of that to be expected in the future years.

(8) Segment Reporting

The Company adopted SFAS No. 131, Disclosures about Segments of an Enterprise
and Related Information, during the fourth quarter of 1998. SFAS No. 131
established standards for reporting information about operating segments in
annual financial statements and requires selected information about operating
segments in interim financial reports issued to stockholders. It also
established standards for related disclosures about products and services, and
geographic areas. Operating segments are defined as components of an enterprise
about which separate financial information is available that is evaluated
regularly by the chief operating decision, or decision making group, in deciding
how to allocate resources and in assessing performance. MathSoft's chief
operating decision making group consists of the Chief Executive Officer, members
of Senior Management and the Board of Directors. The operating segments are
managed separately because each represents a specific type of software
productivity tools for a specific market.

MathSoft's reportable operating segments include the Technical Calculation
Software Product line and the Data Analysis Software Product line. Revenues for
Technical Calculation Software Products are derived from sales of Mathcad,
Electronic Books, Extension Packs and StudyWorks. Revenues from the Data
Analysis Software Product line include S-PLUS licenses, maintenance and
consulting services, add-on modules and StatServer.

The accounting policies of the segments are the same as those described in the
summary of significant accounting policies. MathSoft evaluates performance
based on stand-alone operating segment net income. Revenues are attributed to
geographic areas based on where the end customer is located (see Note 7).
