This Annual Report contains forward looking statements, within the meaning of
the Private Securities Litigation Reform Act of 1995, with respect to the
financial condition, results of operations and business of DTM Corporation (
"DTM", the "Company", or the "Registrant"). Such statements are subject to
certain risks and uncertainties that could cause actual results to differ
materially and adversely from those set forth in the forward-looking statements,
including, without limitation: DTM may not emerge as a market leader, or even a
major market participant and its markets may not develop; price reductions,
reduced margins and loss of market share may occur as a result of increasing
competition; the Company's dependance on a single product that is priced at the
high end of the range for today's rapid prototyping products has caused it to be
adversely affected in a soft market; class action litigation is pending against
the Company; capital sufficient to finance the business may not be obtained;
intellectual property and proprietary rights may not be protected; DTM may fail
to manage or experience future growth; quarterly fluctuations in operating
results may adversely affect stock prices; the difficulty in predicting results
of operations may have a material adverse effect on the price at which the
Common Stock trades; necessary new products may not be developed; key personnel
may leave; suppliers may cause disruptions; actions by foreign governments may
limit sales; a controlling shareholder has an interest in liquidating its
interest in the Company; certain tax benefits obtained from a controlling
shareholder are no longer available ; possible issuance of preferred stock could
impact common stockholders; sales of a large block of stock and sales of shares
issuable pursuant to employee stock options could decrease stock prices; and
market price could be volatile, regardless of DTM's financial performance. The
Company cautions that the foregoing list of important factors is not exclusive.

ITEM 1.    BUSINESS

GENERAL

DTM Corporation develops, designs, manufactures, markets and supports, on an
international basis, rapid prototyping and rapid tooling systems and related
powdered materials and services based on proprietary selective laser sintering
technology initially developed by The University of Texas. This technology uses
laser energy to melt and bond ("sinter") powdered material to create a solid
object. DTM Corporation has an exclusive worldwide license from The University
of Texas (the "UT License") to practice selective laser sintering. The UT
License includes the original patents, plus a right of first refusal to all
improvements thereon. The Company's product line of Sinterstation Systems and
related powdered materials are based on this proprietary and patented selective
laser sintering technology.

Rapid prototyping is the creation of a solid three-dimensional model or
prototype directly from computer aided design ("CAD") data files. Rapid tooling
is the creation of durable tooling that can be subsequently employed to produce
quantities of injection molded plastic parts for market introduction. Use of the
Company's Sinterstation Systems can significantly reduce the time required to
produce models and prototypes for testing actual product fit and form, ergonomic
design and functionality from what otherwise could be months or weeks to days
or, in some cases, hours. The Company's Sinterstation Systems are used in the
design, development and market introduction of products in a wide range of
industries, including, but not limited to, the automotive, aerospace, medical,
electronic, telecommunications, computer, appliance, footwear, toy and power
tool industries.

DTM Corporation was incorporated in 1987. The B.F.Goodrich Company
("BFGoodrich") currently owns approximately 50.2 % of the outstanding Common
Stock.

"ProtoForm," "RapidSteel," "Sinterstation," "SLS" and "TrueForm" are registered

DTM'S SELECTIVE LASER SINTERING TECHNOLOGY

     The Selective Laser Sintering Process

The Company's selective laser sintering process uses laser energy to sinter
powdered material to create solid objects. The Company's Sinterstation Systems
employ a combination of software and hardware to produce functional models and
patterns from powdered materials. The patterns can, in turn, be used for
secondary processes such as the production of non-durable molds and investment
casting. Sinterstation Systems also can be used to produce metal prototype mold
inserts.

Customers input designs into the Sinterstation Systems in the form of CAD
drawings. From the CAD file, Sinterstation Systems produce models, prototypes,
patterns and tooling in the specified shape.

     The RapidTool Process

The RapidTool process employs selective laser sintering along with a polymer
binder infiltration and a furnace cycle to produce steel/copper composite mold
inserts.

A variant of the RapidTool process is the production of mold inserts in
selective laser sintering machines from a copper-reinforced thermoplastic-based
material system. These inserts often can be manufactured in less than 24 hours
in a Sinterstation System without the use of a furnace.


PRODUCTS

     The Sinterstation Systems

DTM's Sinterstation Systems typically include hardware, material handling
equipment, documentation, software licenses, licenses for using DTM-supplied
powdered sintering materials and installation. They can be configured for use
with a single sintering powder or for any combination of thermoplastic, foundry
sands or metal sintering powders. The size and number of objects that can be
built in the build chamber varies depending on the part size, type of sintering
powder used and part configuration. Objects that are larger than the size of the
build chamber can often be built in pieces and then assembled.

The Company has developed a large library of application software designed to
control the selective laser sintering process. This software sets parameters and
directs the various components of the platform hardware based on the type of
material being used in the build process. The Company also has designed a range
of service, support and utility software programs to assist customers in the
prototype and mold building process.

The prices for the Sinterstation Systems sold in 1997 averaged approximately
$346,000, compared to approximately $369,000 in 1996.

The Company sells its Sinterstation Systems with the materials capabilities
selected by the customer and an initial supply of powders. Thereafter customers
can add materials capabilities by purchasing materials start-up modules, which
include an initial supply of materials plus the software developed by the
Company for optimal processing of that particular material. The Company
subcontracts with other manufacturing organizations for the production of
sintering materials or obtains those materials directly from the producer.

RESEARCH AND DEVELOPMENT

The Company's research and development effort focuses on improving core
technologies that are critical to future growth. These include development of
new powdered sintering materials, as well as improved powder handling
technology, laser beam delivery systems and thermal control systems. The
Company's development efforts are augmented by informal development arrangements
with key customers, materials suppliers and hardware suppliers. The Company also
collaborates on research and development with The University of Texas as well as
other universities and research institutions that operate Sinterstation Systems.

During 1997, 1996 and 1995, the Company expended approximately $4.9 million,
$4.3 million and $3.5 million for research and development, respectively. In
part as a result of these R&D efforts, the Company introduced four new sintering
powders in the second half of 1997: Somos 201 powder, a new material supplied by
DuPont that yields highly flexible parts with rubber-like characteristics;
DuraForm Polyamide powder, an improved material for functional prototypes; and
two improved SandForm powders for sand casting applications. In 1996, the
Company introduced the Sinterstation Model 2500.

During 1997, the Company redirected certain research and development resources
to focus on an accelerated project to reduce the manufactured cost of certain of
its products. This project has a goal of allowing the Company more leeway to
handle increased price competition and improve its gross margins. This key
project is scheduled to be completed during 1998. Although the Company has had
success in meeting interim development goals, the reduced cost product has not
yet been fully tested, either in terms of technical performance, or in terms of
market impact. There can be no assurance that the current project or the follow
on projects will be completed successfully or that the desired results will be
achieved. Failure to achieve the ability to lower prices and increase gross
margins could have a material adverse effect on the Company and its financial
performance.

Longer term, the Company believes that the selective laser sintering technology
is capable of processing an even wider range of materials, thereby improving the
performance of the Company's products in current applications and advancing the
technology into new applications. The Company is conducting preliminary
experiments to (i) broaden the performance of the Sinterstation System to
include the production of prototype metal parts, (ii) develop new and improved
functional plastic prototyping materials, (iii) broaden the metal mold inserts
product line to include additional durable materials and (iv) develop ceramic
materials for the production of special tooling and part applications. There can
be no assurance that the Company will be able to develop these new materials or
that, if developed, these materials can be successfully marketed.

In the design of the hardware for its Sinterstation Systems, the Company has
incorporated specialized hardware technologies developed for other industries
and purchases them as components from suppliers. For example, the laser used in
its Sinterstation Systems was developed for and is used by the glass bottling
industry to etch lettering on the glass. Because DTM does not have specialized
hardware design capabilities internally, it could be adversely affected if
suppliers of specialized hardware do not continue to furnish key components, or
make available upgrades and enhancements that contribute to the improvement to
the Company's products. There can be no assurance that available specialized
hardware technologies that meet the Company's reduced cost objectives will be
available as purchased components.

The Company has increasingly relied upon the materials research of companies in
the specialty chemicals industry for formulations of powdered materials to be
used in the Company's Sinterstation Systems. Independent research, development
and manufacture of unique powdered materials could be prohibitive. There can be
no assurance that formulations will be available that meet the Company's goals
of higher performance powdered materials and powdered materials suitable for new
applications.

MARKETING AND CUSTOMERS


     Customers

The Company's Sinterstation Systems are purchased by manufacturers,
universities, military and defense organizations ("manufacturers") and by
service bureaus. These service bureaus utilize rapid protoyping equipment to
provide services to other organizations involved in product development. During
1997, the Company experienced a shift in the mix of its customer base to a
higher proportion of manufacturers. Gross margins realized are not significantly
different between the two groups. However, the sales cycle associated with sales
to manufacturers is generally more protracted than for service bureaus.

Much of the Company's historical growth has come from the sale of products to
service bureaus in North America and Europe. However, sales to service bureau
sector declined from 44% of revenues in 1996 to 38% in 1997. The decline in
service bureau share of revenues was due, in part, to a surplus of selective
laser sintering capacity in North American service bureaus in 1997. As a result,
shipments of Sinterstation Systems to North American service bureaus declined by
10% in 1997. Starting in 1996, the Company has intentionally focused on
expanding its sales to manufacturers. In part, the increase in share to 62% for
the manufacturers sector can be attributed to the Company's increased focus. In
1997, revenues derived for the manufacturers sector increased by 14% over the
prior year.

Many of the Company's customers have purchased more than one Sinterstation. In
1997, approximately 40% of Sinterstation Systems sold by the Company were to
existing customers and in 1996, 24% were sold to existing customers.  DTM has
experienced significant repeat business, but cannot predict that it will
continue to do so. Failure to maintain this repeat business could have a
material adverse affect on the Company and its financial performance.

While the Company anticipates that occasional multiple unit purchases by a
single purchaser could result in a large percentage of total sales being
concentrated in one customer from time to time, it does not consider itself
dependent on any particular customer. However, during 1995 approximately 15% of
total revenues were derived from sales to Compression Inc., a service bureau. In
1997 and 1996, no customer represented 10% or more of DTM's revenues.

     Product Distribution; Foreign Operations

The Company distributes its products in the United States, Canada, Western
Europe and key Pacific Rim and South American countries. In the United States
and Canada, the Company employs a direct sales force. In Germany, DTM GmbH, a
wholly owned German subsidiary, distributes DTM's products. DTM GmbH is a sales
and service organization whose efforts are augmented by sales agents in France,
Italy, Portugal, Spain and Sweden. The Company also distributes its goods and
provides services in the Pacific Rim and South America through a network of
agents, including agents in Argentina, Australia, Brazil, China, Hong Kong,
India, Indonesia, Japan, Malaysia, Singapore, South Korea and Taiwan.

Over the past three years, the growth of the Company's international revenues
has outpaced its North American revenues. The Company `s international revenues
now exceed those from North America as the chart below indicates.

</TABLE>

Gross margins realized domestically were approximately the same as those
realized internationally in 1997. Selling expenses as a percentage of revenues
were also approximately the same in 1997.

     Marketing and Sales

The Company's marketing programs utilize a mix of seminars, trade shows, direct
mailings, literature, videos, press releases, telemarketing, brochures and
customer and application profiles to identify prospects that match a typical
Sinterstation System user profile.

     Seasonality

The Company's revenues are affected by capital budgeting and spending patterns
in the North American market and shortened selling periods in certain
international markets. Due to these seasonal factors, the Company typically
experiences slowdowns in sales of Sinterstation Systems during the first quarter
as the result of capital spending patterns in the North American market and
during the third quarter as the result of shortened selling periods in certain
international markets.

SERVICE AND SUPPORT


The Company maintains a staff of field service and support personnel in Europe,
Singapore and North America. The field service organization is responsible for
installations of new Sinterstation Systems and for conducting the Company's
warranty service and maintenance program.

The Company also maintains a staff of applications support personnel in Europe
and North America. The Company's applications support personnel assist customers
with System operations and provide advice and assistance on building unusually
complicated parts and with keeping customers informed of changes and
advancements in the selective laser sintering technology or Sinterstation System
operating procedures.

The Company's Sinterstation Systems are sold with a broad 12-month warranty on
parts and labor. The Company's customers may continue the level of service
provided by the initial 12-month warranty by purchasing an annual maintenance
contract For those customers choosing not to purchase annual maintenance
contracts, DTM also provides repair and maintenance services on a time and
materials basis.

MANUFACTURING


The Company currently utilizes suppliers to produce certain of the major sub-
assemblies of the Sinterstation Systems. The sub-assemblies are built by
different suppliers and shipped to Austin, Texas, for assembly. The
Sinterstation System then is put through calibration and testing. Assembly and
final testing at the Company's site comprises a 21-day cycle. When the
Sinterstation System arrives at the customer's location, DTM personnel install
it and perform on-site testing.


                                       7
<PAGE>

Procurement lead-time for the major sub-assemblies of the Sinterstation Systems
can be up to 16 weeks. Due to the Company's long lead time for major sub-
assemblies, it places orders for such parts on a forecast basis with the
intention of moving raw materials inventory quickly into work in process. While
the Company subcontracts for manufacture of Sinterstation System components,
powdered sintering materials and accessories from single-source, third-party
suppliers, multiple sources exist for almost all of the components of the
Company's products.

The Company's manufacturing facilities in Austin, Texas, are currently
configured to assemble and test the Sinterstation Systems. The Company believes
that it will have sufficient manufacturing capacity to fulfill demand for its
Sinterstation Systems in 1998. See Item 2  Properties.

INTELLECTUAL PROPERTY


Researchers at The University of Texas initially developed the selective laser
sintering technology commercialized by DTM. The first selective laser sintering
patent was issued to The University of Texas in 1989. The University of Texas
patents covering selective laser sintering begin to expire in 2006. DTM has an
exclusive worldwide license from The University of Texas to use the selective
laser sintering technology, the term of which continues until expiration of the
patent rights that are the subject of the UT License. The UT License includes
the original patents plus a right of first refusal for all improvements thereon.
The UT License requires that DTM commercialize the technology, which DTM has
done and continues to do in key markets. Under the UT License, DTM is required
to make royalty payments equal to 4% of net sales of Sinterstation Systems and
certain powdered materials. In connection with obtaining the UT License, the
Company issued 20,442 shares of Common Stock to The University of Texas. Under
the UT License, The University of Texas reserves the right to practice the
patented technology for research and educational purposes. The UT License can be
terminated by The University of Texas (i) if DTM becomes bankrupt or insolvent,
(ii) if DTM commits a material breach or default under the UT License and fails
to cure that breach or default within 90 days of notice thereof or (iii) as to
foreign jurisdictions, after 1997, if DTM fails to commercialize the technology
in that jurisdiction. The UT License provides that DTM will indemnify The
University of Texas from expenses or damages incurred by The University of Texas
arising from DTM's use of the licensed subject matter.

The Company has further refined and improved the selective laser sintering
process and materials and has been issued patents in its own name for many of
those developments. As of March 2, 1998, the Company owned or had exclusive
licenses to 29 Unites States patents and five allowed Unites States
applications. As of the same date, the Company owned or had exclusive licenses
to five European patents and two allowed European applications. In addition, the
Company owns or has exclusive rights to 15 other issued international patents.
Technology that is covered by existing patents or is the subject matter of
pending patent applications includes some or all of the following: (i) the
fundamental elements of the selective laser sintering process; (ii) related
inventions on powder delivery, beam delivery and thermal control; (iii) certain
of the sintering powders that DTM has developed; (iv) certain combinations of
powdered materials; and (v) certain post-processing steps for part finishing.
Pending patent applications cover recent developments in composite materials, as
well as specially tailored powder formulations that produce exceptional feature
detail and surface finish. It is anticipated that DTM will make additional
patent application filings as a result of research currently in progress.

Some of the Company's patents have been acquired from third parties other than
The University of Texas. DTM acquired certain patents in the powdered materials
area through assignment from BFGoodrich in 1992. Also in 1992, DTM acquired a
patent that was originally issued to Ross Housholder in 1981. The Company
believes that the Housholder patent is a pioneer patent in the rapid prototyping
field. This patent will expire in 1999.

Most of the key claims of the U.S. patents covering selective laser sintering,
excluding the Housholder patent, have been submitted internationally. The first
European Patent Convention patent, which was issued by the European Patent
Office ("EPO") in December 1994, gives patent protection in Austria, Belgium,

                                       8
<PAGE>

France, Germany, Italy, the Netherlands, Sweden, Switzerland and the United
Kingdom. However, this patent is the subject of an opposition proceeding before
the EPO that was initiated by EOS GmbH, a competitor of the Company. The
competitor initially alleged that the patent claims have been the subject of an
unallowable amendment and that the subject matter is not novel and does not
involve an inventive step. In December 1997, the Company received a favorable
ruling from the EPO in response to these allegations. However, EOS GmbH has
recently filed an appeal before the EPO that again alleges the patent is
invalid. The Company intends to defend the validity of this patent vigorously.
See "Item 3  Legal Proceedings"

The Company has four trademarks registered with the U.S. Patent and Trademark
Office.

The Company can give no assurance that the issued patents to which it holds
rights will be adequate to protect its interests or, if challenged, held valid.
The Company's competitors could develop non-infringing systems, materials or
technologies that are equivalent or superior to those of the Company.
Competitors currently do and also may in the future practice technology covered
by DTM's patents or other legal or contractual protections regardless of the
fact that it is legally protected, forcing the Company to engage in costly
litigation to defend its interests. While DTM defends its intellectual property
vigorously, there can be no assurance that it will be successful in its various
litigations in many countries. A failure by the Company to protect its
intellectual property position could have a material adverse affect on its
business, financial condition and results of operations.

COMPETITION


The Company faces significant worldwide competition in the market for rapid
prototyping systems and materials. Several United States-based companies other
than DTM are in various stages of developing and marketing rapid prototyping
systems and services. These companies include 3D Systems Corporation ("3D
Systems"), Helisys, Inc. ("Helisys"), Sanders Prototype, Inc., Soligen
Technologies, Inc. and Stratasys, Inc. ("Stratasys"). Of these, 3D Systems,
Helisys and Stratasys compete with DTM on a worldwide basis. The Company also
faces competition in various regions outside North America from companies such
as EOS and several Japanese companies, including CMET (Mitsubishi) and Teijin.

A number of the companies participating in the rapid prototyping industry have
developed or may be developing desk-top systems that are sold or will be sold
primarily on the basis of price. DTM believes that these companies include 3D
Systems, Denken Engineering Co., Ltd., Helisys, Kira Corporation, Sanders
Prototype, Inc. and Stratasys, among others. Their products are based on ink jet
printing, plastic extrusion or paper laser cutting and laminating technologies
and generally sell for far less than the Company's products, which are not desk-
top systems.

The Company believes that its principal competitors for the plastic model,
functional prototype and pattern-creation segments of the rapid prototyping
market are 3D Systems, Teijin, CMET and EOS. 3D Systems, Teijin and CMET employ
a stereolithography ("SLA")-based process that utilizes ultraviolet light
sources to polymerize liquid monomers into a solid plastic object. 3D Systems
was the first company to commercially introduce rapid prototyping technology.
The Company competes with 3D Systems on a worldwide basis while its competition
to date with CMET and Teijin has been confined to Japan. Before 1997, EOS,
located in Munich, Germany, marketed systems based on both SLA and selective
laser sintering technologies, principally in Western Europe. In 1997, EOS
announced that it had sold its SLA product line to 3D Systems. EOS has been sued
in Germany, France and Italy by DTM for infringement of selective laser
sintering technology patents. See "Business--Intellectual Property" and
"Business--Legal Proceedings." The Company considers a process marketed by 3D
Systems to be worldwide competition for its RapidTool process and an EOS process
to be a competitor of the RapidTool process in Europe and certain Pacific Rim
countries.

The Company competes for business with other rapid prototyping companies
primarily on the basis of product performance and price, as well as reliability,
accuracy and versatility, as well as product service. The Company also competes
for business with conventional machining and milling techniques, which continue
to be the most common methods by which plastic models, functional prototypes and
tool inserts

                                       9
<PAGE>

are manufactured. The Company is experiencing the effects of this significant
competition in the form of sales discounts, additional services and extended
terms.

The Company may be competing with other technologies that lessen the need for
physical models, such as computer visualization and new generation of CAD
programs that more reliably model and present images of assembled products.

The Company's current technology is not amenable to be configured as a desk-top
product. If mechanical design engineers and other users of design, modeling and
prototyping technologies develop a preference for either desk-top rapid
prototyping systems or approaches that are fully electronic as the standard for
proving design specifications, then the Company could be materially adversely
affected.

---------------------------------------------------------------------------------------------------------
</TABLE>

John S. Murchison, III joined the Company as Chief Executive Officer and
President in September 1990. Prior to joining the Company, Mr. Murchison was
General Manager for the Pratt Group, a privately held Australian-based company
with worldwide holdings in packaging, insurance, banking and trading, from 1987
to 1990.

Geoffrey W. Kreiger joined the Company in December 1997 as Controller, Treasurer
and Secretary. Prior to joining the Company was Executive Vice President of
Austin Software Foundry, Inc., from 1996 to 1997. Prior to that he was
President, Datamarine Unit, and Chief Financial Officer and Director of
Datamarine International, Inc., a manufacturer of communications equipment and
consumer electronics, from 1988 to 1995. Mr. Kreiger is a Certified Public
Accountant.

Kevin McAlea, Ph.D. was appointed Vice President, Marketing and Business
Development in 1997. He had been Director of Process and Materials Research
since joining DTM in 1993. Before joining DTM, Dr. McAlea spent more than eight
years in materials research and development for General Electric Company. His
last position was managing the Polymer Physics Program at GE's Corporate
Research and Development Center.

EMPLOYEES


At December 31, 1997, the Company had 113 employees. Approximately 32.0% of the
Company's employees are involved in engineering, research and development and
engineering product support. The remaining employees are engaged in sales,
marketing, finance and administration. A union represents none of the Company's
employees. The Company has no prior experience with a work stoppage. The Company
has experienced the loss of personnel in certain important positions. The future
success of the Company depends on its ability to attract and retain a qualified
work force, including employees with critical management, financial, engineering
and sales and marketing skills.

ITEM 2.    PROPERTIES

The Company currently occupies a 30,000-square foot facility at 1611 Headway
Circle, Building 2, Austin, Texas. The Company's lease on this facility expired
on November 30, 1997. The Company has exercised its option to renew the lease at
then-current market rates and since November 30, 1997 remains in this facility
on a month-to-month basis while it negotiates a new long-term lease agreement.
This facility houses the bulk of the Company's operations except off-site
warehouses in Austin, Texas, primarily for the purpose of storing inventory,
that are leased under short-term arrangements. The Company intends to
consolidate its inventory in the expansion space at its main facility in 1998.
The Company also maintains off-site sales and/or service offices located in
various areas of the United States and in Singapore and offices of the Company's
German subsidiary in Hilden, Germany, all of which are leased. DTM expects that
such facilities will be sufficient to support the Company's operations through
the remainder of 1998. See "Item 1.  Business--Manufacturing."

ITEM 3.    LEGAL PROCEEDINGS


DTM filed an action in the United States District Court for the Eastern District
of Wisconsin in October 1995 against three parties who are operating a
Sinterstation System. DTM alleges that the defendants willfully infringed a DTM
patent on certain selective laser sintering powders. In June 1996, DTM amended
its lawsuit to also assert that one of the defendants breached an oral
settlement agreement. The Company seeks injunctive relief, damages and
attorneys' fees. The defendants have denied infringement and the existence of an
oral settlement agreement, and the defendants seek attorneys' fees. The
defendants have also asserted the affirmative defenses of patent invalidity,
implied license, and failure to mark patented articles, patent unenforceability
and invalidity of the oral settlement agreement. Discovery commenced in late
1995. In a subsequent filing, one of the defendants also has asserted claims
against DTM and BFGoodrich for violation of state and federal antitrust laws.
That defendant seeks injunctive relief as well as damages and attorneys' fees.
In July 1997, the court granted a temporary summary judgment, ruling that these
particular defendants had been given an implied license by DTM. DTM has appealed
this ruling. The contract claim against the defendants and the antitrust claim
against DTM and BFGoodrich remain outstanding and are expected to go to trial
unless this case is settled in the meantime. DTM and BFGoodrich have indicated
that they believe that the subsequent counter and cross claims for violation of
antitrust laws are without merit. It is not possible at this time to predict the
outcome of this proceeding, although a ruling unfavorable to the Company on
either the appeal of the summary judgment ruling or on the outstanding counter
and cross claims could have a material adverse effect on the Company's business
and financial performance.

The Company has initiated proceedings against EOS GmbH and related parties in a
number of courts, primarily in Europe, to enforce its patent rights in various
jurisdictions. The Company initiated patent infringement litigation in March
1996 in the 3rd Chamber--1st section of the Court of Paris, France against EOS
GmbH ("EOS"), a German competitor, against EOS S.A. (France) and against one of
EOS's customers. The Company also initiated patent infringement litigation in
April 1996 in the County Court No. 1 in Munich, Germany against EOS. In December
1996, the Company initiated similar litigation in the court of Pinerolo, Italy,
against EOS. In December 1997, the Company initiated similar litigation in No.
29 Civil Department of Tokyo District Court against Hitachi Zosen Joho System
K.K., an EOS distributor. In each of these cases, the Company has alleged that
EOS is selling rapid prototyping systems in Europe and Japan that make
unauthorized use of selective laser sintering technology covered by the European
and Japanese patents under which DTM has exclusive rights. The Company seeks
injunctive relief plus damages. It is anticipated that this litigation will be
pursued in conjunction with the EPO proceeding in which EOS has opposed the
validity of that European patent. Hearings have begun in the German, French,
Italian and Japanese lawsuits. It is not possible at this time to predict the
outcome of these proceedings. See "Item 1.  Business--Intellectual Property."

EOS has informed the Company that EOS has obtained the worldwide right to
enforce certain U.S. patents owned by 3D Systems. EOS has also informed DTM that
EOS may bring patent infringement litigation

                                       11
<PAGE>
against DTM in the U.S. courts. It is not possible at this time to predict the
outcome of this possible action, although the Company has conducted a review of
the 3D patents and believes that it is not infringing or has valid defenses. If
such a lawsuit is filed, the Company intends to defend itself vigorously.
However, a ruling that would have the effect of allowing EOS to sell rapid
protoyping systems that use selective laser sintering in the U.S. could have a
material adverse effect on the Company's business and financial performance.

The matter styled John H. Danielson and Thomas E. Harding v. DTM Corporation is
currently pending in the 225TH Judicial District in Bexar County, Texas.
Following the Company's June 18, 1997 announcement regarding earnings John J.
Danielson and Thomas E. Harding (jointly "Plaintiffs") filed suit against the
Company on November 18, 1997, in a Texas State Court in Bexar County, Texas.
Plaintiffs allege violation of federal and state securities laws in connection
with the Company's filings and public disclosures related to its initial public
offering on May 2, 1997 (the "IPO"). Plaintiffs have styled their lawsuit as a
class action, and seek to represent a purported class of purchasers of the
Company's stock in connection with the IPO. Although not formally served as of
the date hereof, the Company has been advised that on March 26, 1998, Plaintiffs
filed an amended complaint to expand their allegations and to name the following
individuals and entities as additional defendants with the Company: John S.
Murchison, III, a director and the Company's Chief Executive Officer; D. Lee
Tobler, Chairman of the Board of Directors; Marshall O. Larsen and Steven G.
Rolls, directors of the Company; and A.G. Edwards and Sons, Inc. and Ladenburg
Thalman & Co., Inc., the managing underwriters in the IPO. Plaintiffs seek
rescission and damages. If the class were certified as currently described and
the case decided in favor of the Plaintiffs, damages could include the proceeds
of the Company's IPO or approximately $22.8 million, plus interest and
Plaintiffs' attorneys fees. It is not possible at this time to predict the
outcome of this lawsuit, although the Company believes that the allegations are
without merit and intends to contest them vigorously. However, a ruling
unfavorable to the Company could have a material adverse effect on the Company's
business and financial performance.

 Although the Company believes that it has meritorious defenses to the claims of
liability or for damages in the various actions against the Company, there can
be no assurance that additional lawsuits will not be filed against the Company.
Further, there can be no assurance that the foregoing actions will not have a
disruptive effect upon the operations of the Company's business, or that the
resolution of the foregoing actions will not have a material adverse effect upon
the Company.

The Company has never declared or paid cash dividends on its Common Stock and
does not anticipate that it will pay dividends in the foreseeable future. The
Company intends to reinvest any earnings in the development and expansion of its
business. Furthermore, the Company is now restricted from paying dividends by
the terms of its loan agreement with a bank and it expects that this restriction
will be part of future borrowing arrangements.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS


BUSINESS, ENVIRONMENT AND RISK FACTORS


The following discussion and analysis should be read in conjunction with the
information set forth under "Selected Financial Data" and the Company's
Consolidated Financial Statements and notes thereto as well as the section below
under the heading "Risk Factors That May Affect Future Results and Safe Harbor
Statement." The Company's future operating results may be affected by various
trends and factors, which are beyond the Company's control. These include, among
other factors, changes in general economic conditions, rapid or unexpected
changes in technologies and uncertain business conditions that affect the rapid
prototyping and rapid tooling industry. Accordingly, past results and trends
should not be used by investors to anticipate future results or trends.

With the exception of historical information, the matters discussed below under
the heading "RESULTS OF OPERATIONS" and LIQUIDITY AND CAPITAL RESOURCES" may
include forward-looking statements that involve risks and uncertainties. The
Company wishes to caution readers that a number of important factors, including
those identified in the section entitled "Risk Factors That May Affect Future
Results and Safe Harbor Statement" as well as factors discussed elsewhere in
this report and in the Company's other reports filed with the Securities and
Exchange Commission, could affect the Company's actual results and cause actual
results to differ materially from those forward-looking statements.

OVERVIEW


DTM Corporation develops designs, manufactures, markets and supports, on an
international basis, rapid prototyping and rapid tooling systems and related
powdered sintering materials and services. The Company's Sinterstation Systems
and powdered sintering materials are based on proprietary and patented selective
laser sintering technology. The Company was incorporated in 1987, and prior to
shipment of its first Sinterstation System in 1992, it derived revenues solely
from a service bureau it operated in Austin, Texas.

As more fully described herein, the Company`s revenues have not grown to a level
that will support its cost infrastructure; thus it has yet to report a profit in
any period. Growth in 1997 tapered to 4%, whereas it had been 72% in 1996 and
54% in 1995. In 1997, the growth experienced in 1996 carried into the first two
quarters, but revenues actually decreased in the last two quarters. There was a
particularly steep decrease in sales in the third quarter of 1997 and a large
loss for that quarter was sustained because of this and other factors.

Calendar year 1997 was disappointing due to continuing losses, ongoing softness
in the North American markets, increased price competition world-wide, including
currency effects, and changes in anticipated product mix. In addition, the
Company's RapidTool process is taking longer than previously anticipated to
become a significant factor with customers.

In mid-1997, the Company initiated several internal programs to make the
Company's products more competitive in terms of capability and on price and to
lower its expenses. First, the Company began development of several sintering
materials for making new and improved metal tooling and cores in order to
increase the acceptance of the Company's Sinterstation Systems for these types
of applications. Additional sand core powdered sintering materials were
available by the end of 1997. Second, a project was accelerated to reduce the
cost of the Company's Sinterstation System to make it more competitive. Third, a
cost containment and reduction program was directed at freezing or reducing
overhead expenses to a level commensurate with the Company's current growth.
However, there can be no assurance that the Company will be able to successfully
implement any or all of these initiatives. Any failure to do so could have a
material effect on the Company, its financial condition and results of
operations.

                                       14
<PAGE>

To achieve profitable operations, the Company must grow, while improving its
gross margins and containing its costs. There can be no assurance that the
Company's gross margins will improve in the face of expected future price
declines or other adverse factors and that failure to maintain the Company's
gross margins could have a material adverse effect on the Company's financial
condition and results of operations

A sale by the Company of one of its Sinterstation Systems can generate revenues
of over of $500,000 upon shipment. Thus the delay or acceleration of a small
number of systems can materially affect the operating results of the quarters
involved. Furthermore, new product introductions, seasonality of customer buying
patterns and other factors can cause fluctuations in quarterly operating
results.

</TABLE>

Revenues. Revenues increased 3.8% to $25.3 million in 1997 as compared to $24.4
million in 1996 and $14.2 million in 1995. The growth in revenues in 1997 was
attributable to market growth internationally as revenues derived
internationally grew by approximately 30% to $15.8 million, while revenues
derived from customers in North America declined by approximately 22% to $9.5
million. The growth in 1997 was also attributable to manufacturers and others
engaged in product development as sales to these customers grew by approximately
14% to $15.6 million, while revenues derived from service bureaus declined by
approximately 9% to $9.7 million. Rapid prototype service bureaus are primarily
based in North America.

The growth in 1997 occurred in the first two quarters of 1997, with revenues
contracting in the last two quarters of 1997. See "SELECTED QUARTERLY RESULTS"
below. Unit volumes of Sinterstation Systems and most powdered materials
increased slightly during 1997.

                                       15
<PAGE>

As stated above, the Company's 1997 international revenues were $15.8 million or
62% of total revenues, compared to 50% and 34% of total revenues in 1996 and
1995, respectively. Germany was the only foreign country from which more than
10% of the Company's revenues were derived. Revenues derived from German
customers amounted to approximately 27%, 23% and 15% of total revenues in 1997,
1996 and 1995, respectively. Except in Germany, the Company's international
revenues were primarily denominated in U. S. dollars. The Company does not hedge
all of its foreign currency exchange rate risk. The effect of foreign exchange
rate fluctuations on exchange transactions and translation of foreign operations
did not have a significant impact on the Company's operating results in any
period. However, in 1997 DTM did experience downward pressure on its
international prices as the U.S. dollar strengthened significantly against most
European and Asian currencies. If this strengthening continues, the Company
expects continued downward pressure on the Company's sales prices in the
international markets.

Revenues in past periods may not be indicative of revenues in the future, which
may be affected by other business environment and risk factors previously
discussed, as well as other factors included elsewhere herein.

Gross Profit.  Gross profit was $10.6 million or 41.8% of revenue in 1997,
compared to $9.9 million or 40.7% and $4.5 million or 31.9% of total revenue in
1996 and 1995, respectively. The gross profit increase was due to sequentially
higher worldwide unit volume each year. The gross margin percentage increase in
1997 was affected primarily by a product mix shift toward powdered materials,
including increased volumes of nylon powders. The gross margin percentage
increase in 1996 was affected primarily by the introduction of the Sinterstation
2500. The service and support gross margin has been declining due primarily to
the cost of servicing certain international customers.

The Company believes there is a risk that gross margin percentages may decline
in the face of the soft North American market and the strong U.S. dollar. Other
factors, including changes in material and labor costs, may also have an adverse
effect on gross margins. Past gross margins are not necessarily indicative of
future gross margins.

Selling, General and Administrative Expense.  Selling, general and
administrative expense was $10.6 million or 41.8% of revenues in 1997, compared
to $10.0 million or 40.9% of revenues and $6.6 million or 46.6% of revenues in
1996 and 1995, respectively. The increase in both 1997 and in 1996 was primarily
related to the increased costs associated with sales and sales support staffs
and commission expense resulting from higher sales levels.  Selling, general and
administrative expense may vary as a percentage of revenues in the future.

Research and Development Expense. Research and development expense grew by 13.5%
to $4.9 million in 1997, from $4.3 million in 1996 and $3.5 million in 1995. As
a percentage of revenues, research and development expense was 19.2%, 17.6% and
24.8% in 1997, 1996 and 1995, respectively. The increase in expense relates to
the Company's continued development of enhancements to and lower the
manufactured cost of its current products and to the development of new powdered
sintering materials. During the year, the Company continued development in the
areas of powdered materials for use in rapid prototyping, powdered materials for
use in rapid tooling and reducing the manufactured cost of the Sinterstation
Systems. In 1996, the Company developed the Sinterstation model 2500. The
Company plans to continue its commitment to research and development in 1998, as
the Company believes that the markets for its products are characterized by
technological innovation for hardware, software and powdered materials. Research
and development expense may increase in absolute dollars in future periods, and
such expenditures may vary as a percentage of sales. There can be no assurance
that the Company's research and development efforts will result in commercially
successful new technology and products in the future, and those efforts may be
affected by other factors.

Stock Compensation (EAP). In connection with the 1997 IPO, the Company incurred
a one-time non-cash stock compensation expense of approximately $2.9 million as
a result of previously outstanding stock appreciation rights converting by
formula into immediately vested stock options at exercise prices below the
market value of the common stock. This charge was recorded in the second
quarter.

                                       16
<PAGE>

Interest Expense. Net interest expense for 1997 was $325,000, a decrease of
$741,000 compared to interest expense of $1.1 million for 1996 and $530,000 in
1995. This reflects the increase in the average daily balance of the Company's
outstanding indebtedness over 1996 and into May 1997, and then a decrease when
the Company repaid substantially all of the then outstanding indebtedness out of
the proceeds of the IPO.

Cost of Discontinued Registration. In the fourth quarter of 1996, the Company
expensed $752,000 of legal, accounting and other professional services related
to an attempted initial public offering, which was commenced in 1996 and
postponed.

Income Taxes. As a result of its tax sharing arrangement with BFGoodrich, the
Company was allocated an income tax benefit of $827,000 in 1997 compared to $1.7
million in 1996 and to $2.1 million in 1995. In May 1997, BFGoodrich ownership
interest fell below 80% and such benefits are no longer available to the
Company. In the fourth quarter of 1997 the Company recorded the final accounting
for this tax allocation arrangement.

Net Loss. The Company had net losses of $7.3 million, $4.5 million and $4.0
million in 1997, 1996 and 1995, respectively.

LIQUIDITY AND CAPITAL RESOURCES


Since the Company's inception, cash used by the Company for operations and
capital investment has exceeded cash generated by the Company. Through May 1997,
the Company generally had financed its needs through collection of revenues and
transactions with BFGoodrich and borrowings from commercial banks and other
short-term sources.

In May 1997, the Company issued common shares in an initial public offering. The
net proceeds of approximately $20.7 million were used to pay off substantially
all of the Company's then outstanding debt and to add approximately $6.0 million
to working capital.

Net cash used in operating activities (before working capital changes) was $2.0
million in 1997, while it was $2.3 million in 1996 and $1.5 million in 1995.
Working capital used cash of $932,000 in 1997, $1.8 million in 1996 and $85,000
in 1995. The Company's working capital needs increase during periods of rapid
growth such as occurred in 1996 because of a number of factors, including the
duration of the Company's manufacturing cycle and collection cycle. In 1997 the
growth tapered and receivables were a source of cash that was applied to reduce
current a liabilities. However, a $1.0 million increase in inventories during
1997 used a corresponding amount of cash. The Company attributes this build-up
in inventories to slower than expected sales in the third and fourth quarters.
The Company believes that the level of finished goods on hand at December 31,
1997 will be reduced during 1998, as it sells off this inventory.

For the years ended December 31, 1997, 1996 and 1995, BFGoodrich allocated to
the Company approximately $827,000, $1.7 million and $2.1 million, respectively,
for tax benefits resulting from inclusion of the Company in the consolidated
income tax return of BFGoodrich. Such amounts are included in "Due to/from
BFGoodrich" in changes in assets and liabilities used in operating activities
(working capital) in the Consolidated Statements of Cash Flows in the
Consolidated Financial Statements. See Note 9 to the Consolidated Financial
Statements.

The Company's investing activities include expenditures for patents and
licenses, capitalized software costs and furniture and equipment, principally
consisting of the Company's Sinterstation Systems built for internal use and
rental purposes. Net cash used by investing activities was approximately, $1.7
million, $3.0 million and $2.4 million in 1997, 1996 and 1995, respectively. For
1998, the Company has budgeted for capital expenditures of approximately $1.9
million.

The Company currently has a $2.0 million line of credit with Chase Bank, Texas
NA, with no amounts outstanding, due in April 1999. Borrowings under this line
of credit bear interest at prime plus 1.5%. Borrowings under this line must be
approved in advance by BFGoodrich, which has provided its guarantee of the line
to Chase Bank, Texas NA. There can be no assurance that BFGoodrich will approve
such bank loans when and if requested by DTM. In addition BFGoodrich has
expressed its intention to divest its interest in the Company. If BFGoodrich
were to divest its interest in the Company, it is unlikely that it would subject
itself to additional guarantee exposures under the bank agreement.

The Company believes that it has the financial resources needed to meet business
requirements, including capital expenditures, working capital requirements, the
debt obligations outstanding and operating lease commitments for facilities at
least through the next twelve months. However, there can be no assurance that
this will be the case.

EFFECT OF INFLATION


The Company's business operations are subject to inflationary pressures. Due to
the competitive environment in this industry, there can be no assurance that the
Company will be able to increase prices in the event of increased labor and
material costs.

                                       19

YEAR 2000 PLAN


The Company believes that its Sinterstation Systems have no exposures with
respect to the year 2000 issue.

The Company has begun to develop a plan to upgrade or replace its information
technology to recognize the year 2000 and begun to evaluate packaged software
solutions. The Company currently expects the project to be substantially
completed by early 1999 and to cost between $50,000 and $150,000. This estimate
includes internal costs, but excludes the costs to upgrade and replace systems
in the normal course of business. The Company does not expect this project to
have a significant effect on operations. As of December 31, 1997, approximately
$10,000 was expensed.

RISK FACTORS THAT MAY AFFECT FUTURE RESULTS AND SAFE HARBOR STATEMENT


Investors are cautioned that this Form 10-K contains forward-looking statements
that involve risks and uncertainties, including the following: (i) the Company's
plans, strategies, objectives, expectations and intentions are subject to change
at any time at the discretion of management and the Board of Directors; (ii) the
Company's plans and results of operations will be affected by the Company's
ability to manage its growth and working capital; (iii) the Company's business
is highly competitive and the entrance of new competitors or the expansion of
the operations by existing competitors in the Company's markets could adversely
affect the Company's plans and results of operations. In addition, the Company
identifies the risk factors discussed below which may affect the Company's
actual results and may cause actual results to differ materially from those
contained in forward looking statements.

LIMITED OPERATING HISTORY AND LACK OF PROFITABILITY. The Company was
incorporated in 1987, and prior to shipment of its first Sinterstation Systems
in 1992, it derived revenues solely from a rapid prototyping service bureau that
it operated in Austin, Texas. The Company has been unprofitable from its
inception; most recently recognizing a net loss of approximately $7.3 million
for the year ended December 31, 1997. There can be no assurance that the Company
can achieve or maintain profitability in the future.

EMERGING RAPID PROTOTYPING MARKET. The market for rapid prototyping products and
services is in an early stage of development and includes multiple, competing
technologies, many of which are not yet fully developed. Participants in this
market are moving to address new applications, many of which may not yet be
known or accepted by potential users. Rapid prototyping requires that a CAD file
describe a design. Organizations who are not using CAD are not, generally,
potential customers for rapid prototyping products and services. Significant
education of the end user in both CAD modeling and rapid prototyping in general
has in some cases been a prerequisite to product acceptance. It is not clear at
this time which one or more technologies will gain broad market acceptance.
There can be no assurance that DTM will emerge as a market leader, or even a
major market participant, as the market matures.

EMERGING RAPID TOOLING MARKET. The market for rapid tooling products and
services is even in an earlier stage of development than rapid prototyping.
Participants in this market are moving to address new applications, many of
which may not yet be known or accepted by potential users. The Companies who
make tooling using traditional machining methods have made large capital
investments in traditional equipment and have mature infrastructures for doing
so and may be highly resistant both on financial and cultural basis to adopting
new technologies. There can be no assurance that rapid tooling technologies will
evolve to the point that the perceived value will overcome those obstacles.
There can be no assurance that DTM will emerge as a market leader, or even a
major market participant, as the market matures.

PENDING CLASS ACTION LITIGATION. The Company is the defendant in a matter styled
as a class action that is pending in a Texas State court. The plaintiffs seek
recission of the May 1997 IPO and the return to certain shareholders the
proceeds of that IPO of approximately $22.8 million, plus interest and costs. An
adverse judgment may have a material adverse effect on the Company's business
and financial performance. See "Item 3. Legal Proceedings"

                                       20
<PAGE>

COMPETITION. The market for rapid prototyping systems is intensely competitive.
In marketing its Sinterstation Systems, the Company experiences competition from
many sources. Certain of the Company's competitors are better known and have
greater financial, research and development, production and marketing resources
than DTM. Competition has increased as a result of the introduction of new
products or product enhancements by these competitors or the entry into the
industry by other companies. Industry analysts have estimated that the worldwide
market for rapid prototyping grew in 1997 by 20%. In 1997, the Company's
revenues lagged the overall industry and grew by only 4%. Increased competition
has resulted in price reductions, reduced margins and loss of market share, all
of which have materially adversely affected the Company's business and financial
results. See "Item 1. Business--Competition."

LIMITED PRODUCT COMPANY. The Company currently offers two models of
Sinterstation Systems for sale. The sale of Sinterstation Systems comprised 66%
of revenues in both 1997 and 1996. The remaining revenues were comprised of
sales of sintering materials, spare parts and services to the installed base of
Sinterstation owners. The Sinterstation Systems are priced at the premium end of
the range of today's rapid prototyping products and are sold on the basis of
performance and suitability to specific applications. In a downturn or even in a
soft market the Company's dependance upon a limited range of products, as
opposed to a wide range of products at different price points, has caused the
Company's financial performance to be adversely affected.

CAPITAL RESOURCES. The Company's future capital requirements will depend on a
number of factors, including its profitability, growth rate, working capital
requirements, expenses associated with protection of its patents and other
intellectual property and costs of future research and development activities.
It is typical of developing technology companies to need large amounts of
capital to fund growth. BFGoodrich, the Company's majority shareholder, has been
a significant source of debt and equity funding in the past. BFGoodrich has
indicated to the Company that BFGoodrich has no plans to provide future funding.
In 1997, cash used in operating activities (before working capital changes)
amounted to $2.0 million and net cash used for capital expenditures was $1.8
million for a total of $3.8 million, which was financed, primarily, through the
proceeds of the IPO. At December 31, 1997, DTM had working capital of $5.0
million. Future operating results will depend, in part, on the Company's ability
to obtain and manage capital sufficient to finance its business. The inability
of the Company to secure capital funding sufficient to meet its needs could have
a material adverse effect on the Company's business and financial performance.

INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS. Protection of the Company's
intellectual property is an important factor in its ability to be successful in
a highly competitive market that is subject to rapid technological changes.
However, it is expensive and consumes a significant portion of time of DTM's
officers. Patent and license capital expenditures were $620,000, $698,000 and
$247,000 in 1997, 1996 and 1995, respectively. Royalty expense, included in cost
of sales, was $552,000, $676,000 and $424,000 in 1997, 1996 and 1995,
respectively. In addition, certain litigation expenses were included in Selling,
General and Administrative expense in 1997, 1996 and 1995.

In pursuing protection for its proprietary rights in its Sinterstation Systems,
materials and related technology, the Company currently relies on a combination
of patent, copyright, trademark and trade secret rights, as well as contractual
provisions. The Company typically seeks patent protection for its selective
laser sintering technology, including, where deemed appropriate, the selective
laser sintering process, the Sinterstation Systems and the materials used in the
Sinterstation Systems. However, patent protection may not always be available.
There can be no assurance that patents will be issued under any or all of the
patent applications to which the Company has rights. In addition, the laws of
various countries in which the Company's products may be sold may not protect
the Company's products and intellectual property rights to the same extent as
the laws of the United States.

Furthermore, the Company can give no assurance that the issued patents to which
it holds rights will be adequate to protect its interests or, if challenged,
held valid. The Company's competitors could develop non-infringing systems,
materials or technologies that are equivalent or superior to those of the
Company. Competitors currently do and also may practice technology covered by
DTM's patents or other legal or contractual protections regardless of the fact
that it is legally protected, forcing the Company to engage in costly litigation
to defend its interests. While DTM defends its intellectual property vigorously,
there can be no

                                       21
<PAGE>

assurance that it will be successful in its various litigations in many
countries. If the Company were unsuccessful in enforcing its intellectual
property rights or other contractual rights in the context of third-party offers
to sell selective laser sintering systems or sintering powders or if the Company
were found to have violated state or federal antitrust laws, the Company's
future revenues might be adversely affected. In 1997, a court granted a
temporary summary judgment, ruling that a customer had been given an implied
personal license by DTM to one of DTM's patented sintering materials. This
ruling has been appealed by the Company. The inability of the Company to
successfully establish and defend its intellectual property rights could have a
material adverse effect on the Company's business and financial performance. See
"Item 1. Business--Intellectual Property" and "Item 3. Legal Proceedings."

Unrelated third parties hold many patents and pending patent applications under
which the Company is not a licensee that relate to the design and manufacture of
rapid prototyping systems and materials. If such a third party brought
infringement litigation against the Company, and if the Company was not
successful in defending such litigation or in obtaining a license, the Company's
business and financial performance could be materially adversely affected. The
Company has been threatened with such litigation by a competitor. See "Item 1.
Business--Intellectual Property" and "Item 3. Legal Proceedings."

Certain key intellectual property used in the selective laser sintering process
is licensed to the Company by The University of Texas System. As a licensee, the
Company's rights to practice the technology are not absolute. The University of
Texas could terminate, attempt to terminate or amend the license if the Company
could be shown to be in material default of the terms of the license. Even if
DTM has a basis for objection, defense of its rights as a licensee could be
costly and the outcome would be uncertain. Loss of significant rights as a
licensee under this license could have a material adverse effect on the
Company's business and financial performance. See "Item 1. Business--
Intellectual Property."

MANAGEMENT OF VARYING GROWTH. DTM has experienced varying revenue growth since
1991, recognizing increases in total net revenues from approximately $1.1
million in 1991 to approximately $25.3 million in 1997. In the third quarter of
1997, revenues began to contract overall and throughout 1997 its revenues
derived from North America contracted while its revenues derived from
international markets expanded rapidly. Also, in 1997 the Company's revenues
from customers directly involved in product development expanded while its
revenues derived from service bureaus contracted. This varying growth has, from
time to time, strained its management resources and systems. DTM's ability to
manage its varying growth effectively will depend on, among other things, its
ability to increase the capability and quality of its operational, financial and
management information systems and controls and to train, motivate, in some
cases re-deploy, manage and retain its employees. There can be no assurance that
the Company will experience future growth or be successful in managing any
future growth. Failure to manage or enter into any future growth could have a
material adverse affect on the Company's business and financial performance.

QUARTERLY FLUCTUATIONS IN OPERATING RESULTS. The Company's revenues and
operating results have varied substantially from quarter to quarter and may
continue to do so. DTM typically experiences a relatively long lead-time to
complete a Sinterstation System sale and has historically experienced no
backlog. Furthermore, new product introductions, seasonality of customer buying
patterns and other factors can cause fluctuations in quarterly results. These
fluctuations have and may continue to preclude the Company from managing its
operating results effectively from quarter to quarter. Further, a majority of
the sales of the Company's Sinterstation Systems occur at the end of the
quarter. As the duration of the current manufacturing cycle is approximately 19
weeks, this has a significant impact on the Company's ability to control its
inventories. The bunching of sales at the end of the quarter also negatively
impacts the Company's ability to predict sales, control sales prices and enforce
its standard terms. The failure of the Company to complete a particular
Sinterstation System sale in any given quarter can have a material adverse
effect on the Company's business and financial performance for that quarter and
quarterly fluctuations could cause a material adverse effect on the price at
which the Common Stock trades. See "Item 7. Management's Discussion and Analysis
of Financial Condition and Results of Operations--Selected Quarterly Results"
and "Item 1. Business--Seasonality."

NEW PRODUCTS; ENGINEERING TESTING DELAYS. The Company's ability to achieve and
maintain a significant market share depends heavily on its ability to improve
the perceived value of its Sinterstation

                                       22
<PAGE>

Systems, through a combination of lower installed cost, lower operating costs,
higher productivity and improved ease of use. In addition, DTM must introduce
new and innovative products that facilitate increased use and more specialized
applications of existing products. DTM cannot predict with any certainty the
degree to which its ongoing research and development efforts in the areas of
Sinterstation System and materials enhancements will be successful or, if so,
when. In addition, the Company can provide no assurance of its future success in
selecting, developing, manufacturing and marketing new products. When the
Company or its competitors announce new products with capabilities or
technologies that have the potential to replace the Company's existing product
offerings, customers sometimes defer or forego purchases of existing Company
products. This could materially adversely affect the Company's business and
financial performance. While the Company performs testing prior to releasing new
product designs or product enhancements, products may contain unforeseen errors
or performance problems. The correction of errors and problems in new products
could cause delays in product introductions or shipments, require design
modifications to previously shipped products or cause adverse publicity, any of
which can adversely affect the Company's business and financial performance.

DEPENDENCE ON KEY PERSONNEL. The Company's success depends to a substantial
extent on certain key employees. Losing the services of one or more key
employees could have a material adverse effect on the Company's business and
financial performance. The Company's success also depends on its ability to
continue to attract highly talented technical personnel. Candidates with
appropriate training and expertise may be in short supply in the geographic
areas where the Company is attempting to recruit personnel. While the Company
has put in place incentive compensation plans intended to provide motivation for
continued employment of key employees, most of the employees are not a party to
employment or non-competition agreements with the Company. During the last half
of 1997, several executive officers left the Company, including the Vice
Presidents of Engineering and Marketing and the Chief Financial Officer. The
exercise prices of employee stock options have generally been above market value
since 1997, management incentive goals have not been met for the past two years
and certain sales force incentive goals were not met last year. The Company can
give no assurance that it will be able to retain employees or continue to
attract, assimilate and retain other skilled personnel.

DEPENDENCE ON THIRD-PARTY SUPPLIERS. The Company subcontracts for manufacture of
Sinterstation System components, powdered sintering materials and accessories
from single-source, third-party suppliers. A disruption in supply or failure of
a supplier to remain competitive in functionality or price could have a material
adverse effect on the Company's sales or reputation for timely delivery, and,
hence, on the Company's business and financial performance. See "Item 1.
Business--Manufacturing."

INTERNATIONAL OPERATIONS. The Company competes on an international basis through
its wholly owned subsidiary located in Germany and through export sales derived
from its United States sales operations, principally to the Pacific Rim, Europe
(excluding Germany) and South America. In 1997, approximately 62% of the
Company's sales were made to customers outside of the United States. The Company
expects that sales to customers in countries outside of the United States will
continue to make up a significant percentage of total sales. Fluctuations in
exchange rates as well as interest rates have significantly affected DTM's sales
in foreign markets. In particular, a strengthening U.S. dollar has adversely
affected the price competitiveness on revenues realized on DTM's sales of
products and services.

The Company also maintains a subsidiary for sales and technical support in
Europe. In addition, exchange rates have adversely affected the value of
receivables arising from foreign sales. The Company does engage in some hedging
to limit the currency exchange risk related to some sales. There can be no
assurance that the Company's exposure risks associated with to international
operations will not have a material adverse effect on its liquidity, capital
resources and results of operations. The regulatory environment, including
import/export laws, protective trade policies and currency controls of foreign
governments, also could materially adversely affect the Company's business and
financial performance. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

CONTROL OF THE COMPANY. BFGoodrich owns approximately 50.2% of the outstanding
Common Stock. At this percentage, BFGoodrich could control elections of the
Company's Board of Directors and could control or substantially affect the
outcome of certain matters submitted to the Company's shareholders for their
vote or consent, and to prevent or delay a change in control of the Company.
BFGoodrich has advised the Company that its interest in DTM is primarily
financial and that it intends to

                                       23
<PAGE>

divest its interest in the Company. The Company cannot predict the effect of a
sale of a controlling interest in the Company; although, depending on the
identity of the purchaser and its reason for acquiring control of the Company,
minority shareholders could be adversely affected.

LOSS OF TAX ALLOCATION AGREEMENT AND OTHER BENEFITS FROM BFGOODRICH. As a result
of the IPO, the ownership of outstanding Common Stock by BFGoodrich decreased to
less than 80%. BFGoodrich is no longer able to include DTM's income or loss in
BFGoodrich's consolidated federal income tax return; consequently, DTM has lost
the benefit of the tax allocation agreement between DTM and BFGoodrich effective
May, 1997. Without the tax benefit allocated from BFGoodrich, the Company's net
loss for 1997 would have increased from approximately $7.3 million to
approximately $8.1 million. To the extent the Company incurs future losses, the
resulting tax loss carryforward would be deferred until sufficient income is
generated by DTM to utilize the carryforward.

Historically, DTM has received certain tangible and intangible benefits from
BFGoodrich. For example, BFGoodrich currently provides DTM participation in a
group program for various types of business insurance. This arrangement is on
terms that could be considered more favorable to the Company than those that
would be available to DTM in arms-length transactions with unrelated vendors,
principally because DTM is able to take advantage of cost efficiencies
experienced by BFGoodrich due to the size of its operations. DTM will be
ineligible to take part in some insurance once BFGoodrich no longer owns a
majority of the outstanding Common Stock. Either party has the option to
terminate any of such arrangements at any time. In addition as of December 31,
1997, DTM had a current liability to BFGoodrich in the amount of $909,000. This
amount is currently non-interest bearing and is due on demand. The balance is
the result of certain payments made by BFGoodrich on behalf of DTM. This
arrangement could change at any time.

POSSIBLE ISSUANCE OF PREFERRED STOCK. The Company's Articles of Incorporation
authorize the issuance of up to 3,000,000 shares of preferred stock, $.001 par
value (the "Preferred Stock"), the terms of which would be determined by the
Board of Directors at the time of issuance, without further shareholder
approval. The Board of Directors would determine whether these shares would
carry voting rights, preferences in the payment of dividends, sinking fund
provisions and liquidation, redemption or conversion rights, if any. The Company
has no current plans to issue Preferred Stock. However, if such stock is issued
in the future, the rights of the holders of Common Stock could be materially
adversely affected. It is possible that the Board of Directors could grant
future holders of Preferred Stock rights that could restrict the Company's
ability to merge or sell its assets to a third party, resulting in preservation
of the control of the Company by its then current owners. The Preferred Stock
provisions of the Company's Articles of Incorporation could inhibit a third
party from acquiring a significant amount of the Common Stock, thereby delaying
or preventing changes of the management or control of the Company, and possibly
materially adversely affecting the Common Stock price as a result.

SHARES ELIGIBLE FOR FUTURE SALE.  All shares of the Common Stock owned by
BFGoodrich are freely tradeable, subject to volume limitations of Rule 144. In
addition, BFGoodrich has rights to require the Company to register sales of its
shares of Common Stock under the Securities Act in certain circumstances.

DTM employees hold immediately exercisable options to purchase 553,150 shares of
Common Stock under the Equity Appreciation Plan. The Company registered the
issuance and the sale of the shares of Common Stock that would be issued upon
exercise of options under the Equity Appreciation Plan on a Form S-8
Registration Statement. As a result, the Common Stock acquired by employees of
DTM upon exercise of options outstanding under the Equity Appreciation Plan will
be freely tradeable (subject to compliance with certain provisions of Rule 144,
in the case of affiliates of the Company).

Sales of shares of Common Stock into the market by current shareholders or
employees exercising options could cause a decline in the price of such stock.

MARKET VOLATILITY. The Company is listed for quotation of the Common Stock on
the NASDAQ National Market. Historically, the stock market has experienced
volatility that has particularly affected the


                                       24
<PAGE>

market price of common stock of technology-related companies. That volatility
sometimes has been unrelated to the operating performance of such companies.

                         REPORT OF INDEPENDENT AUDITORS



Board of Directors and Shareholders
DTM Corporation

We have audited the consolidated balance sheets of DTM Corporation and its
subsidiary as of December 31, 1997 and 1996, and the related consolidated
statements of operations, shareholders' equity (deficit) and cash flows for each
of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of DTM Corporation
and its subsidiary at December 31, 1997 and 1996, and the consolidated results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted accounting
principles.

                  Notes to Consolidated Financial Statements

                               December 31, 1997


1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION

DTM Corporation ("DTM" or the "Company") was formed in November 1987. Through
the proprietary and patented selective laser sintering ("SLS") process, the
Company is engaged in the development, design, manufacture, marketing and
support of rapid prototyping and rapid tooling systems. This technology,
exclusively licensed to DTM by The University of Texas, enables the fabrication
of three-dimensional solid models, prototypes or tool inserts directly from
three-dimensional computer aided design ("CAD") data. The Company's products,
related materials and maintenance and support services are available to the
worldwide, rapid prototyping market. The financial statements include the
accounts of DTM GmbH, a wholly owned German subsidiary. All significant
intercompany accounts and transactions have been eliminated.

In May 1997, the Company issued 2,852,191 common shares in a stock offering to
the public at a price of $8.00 per share. The proceeds of the offering were used
to pay off substantially all of the Company's debt and to add approximately
$6,000,000 to working capital. Prior to the stock offering, DTM was 91.55
percent owned by The BFGoodrich Company ("BFGoodrich"). At December 31, 1997,
after the stock offering and the exercise of employee stock options, DTM was
50.22 percent owned by BFGoodrich. Prior to the stock offering, DTM was
substantially reliant upon BFGoodrich for capital funding or other financial
assistance to enable DTM to meet its financial obligations.

Although DTM's financial position improved during 1997 (due to the receipt of
the cash proceeds from the stock offering and the repayment of substantially all
of the then outstanding debt), DTM continues to incur operating losses and
generate negative cash flows from operating activities.

Management has plans to improve the results of operations of the Company, which
include cost reduction efforts and a focus on increasing revenue through sales
of products and services. Based on management's cash flow projections for 1998,
management believes that the Company will have sufficient working capital to
operate the business during 1998. In the event that the Company requires
borrowings to finance operations in 1998, the Company currently has a $2,000,000
line of credit with a bank (see Note 7). Amounts drawn down under the line of
credit, if any, require the advance approval of BFGoodrich, and any such amounts
(up to the $2,000,000 amount) outstanding will be guaranteed by BFGoodrich.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

INVENTORY

Inventories are carried at the lower of cost or market, with cost determined
using the first-in, first-out (FIFO) method.

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

LONG-LIVED ASSETS

Property

Property includes equipment, office furniture and leasehold improvements and is
recorded at cost. Depreciation expense is calculated on the straight-line method
over the useful life of each asset, which lives range from three to five years.
Leasehold improvements are amortized on the straight-line method over the life
of the related lease or the useful life of the respective asset, whichever is
shorter.

Capitalized Software Development Costs

The Company's principal products include a software component. Costs incurred in
the development of software, once technological feasibility has been established
but prior to general release to customers, are capitalized. Technological
feasibility is established when a product design and working model of the
software product have been completed and when the completeness of the working
model and its consistency with the product design have been confirmed by
testing. Amortization is provided on a product by product basis at the greater
of amortization based on the estimated revenues of the products or the
straight-line amortization over their estimated economic lives of not more than
three years. DTM capitalized software development costs of $268,000 in 1997,
$374,000 in 1996 and $440,000 in 1995. Amortization expense of capitalized
software development costs of $363,000 in 1997, $369,000 in 1996 and $561,000 in
1995 is included in cost of product sales in the consolidated statements of
operations.

Patent and License Fees

Patent and license fees represent the costs associated with filing and
maintaining patent applications and obtaining, maintaining and defending rights
under patents under which DTM operates. DTM capitalized patent and license fees
of $620,000 in 1997, $698,000 in 1996 and $247,000 in 1995. These fees are
amortized for accounting purposes over a five-year estimated economic useful
life utilizing the straight-line method and are included in selling, general and
administrative expense.

The Company evaluates the carrying values of long-lived assets to determine if
the facts and circumstances suggest that they may be impaired. If this review
indicates that long-lived assets will not be recoverable, as determined based on
the undiscounted cash flows of the entity over the remaining amortization
period, the carrying value of the long-lived assets will be reduced accordingly.

TRANSLATION OF FOREIGN SUBSIDIARY FINANCIAL STATEMENTS

The financial statements of DTM GmbH (a wholly-owned subsidiary located in
Germany) are translated to U.S. dollars substantially as follows: all assets and
liabilities at year-end exchange rates; sales and expenses at average exchange
rates; and shareholders' equity at historical exchange rates. Gains and losses

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

RECOGNITION OF REVENUE

Revenues from the sale of SLS systems are recognized when title has transferred
to the customer, when the Company's remaining obligations are insignificant and
when collectibility of the related receivable is probable, which is upon
shipment. The Company defers from three to six percent of the revenues,
excluding certain accessories, from each SLS system sale for warranty service.
This deferred amount represents the Company's estimate of the cost of providing
such warranty service and is recognized ratably as service and support revenue
over the 12-month warranty period.

Upon expiration of the 12-month warranty period discussed above, the Company
offers for sale to its customers an annual maintenance contract, the revenues
from which are recognized ratably as service and support revenue over the
related support period.

NET LOSS PER SHARE

In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share. Statement 128 replaced the calculation of primary and fully
diluted earnings per share with basic and diluted earnings per share. Unlike
primary earnings per share, basic earnings per share exclude any dilutive
effects of options, warrants and convertible securities. Diluted earnings per
share are very similar to the previously reported fully diluted earnings per
share. All net loss per share amounts for all periods have been presented, and
where appropriate, restated to conform to the Statement 128 requirements.

CONCENTRATION OF CREDIT RISK

The Company sells its products and services to companies in diversified
industries. Credit is extended based on an evaluation of each customer's
financial condition, generally without requiring collateral. The Company
monitors its exposure to credit losses and maintains allowances for potential
losses.

DEPENDENCE ON THIRD-PARTY SUPPLIERS

The Company subcontracts for the manufacture of product sub-assemblies from
single-source, third-party suppliers. In addition, the Company has adopted a
"just-in-time" inventory system for product sub-assemblies and relies on
suppliers to provide components on a timely basis.

ADVERTISING COSTS

Advertising costs, which are expensed as incurred, were $482,000 in 1997,
$757,000 in 1996 and $596,000 in 1995.

STOCK-BASED COMPENSATION

The Company accounts for its stock-based compensation in accordance with the
provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees, and
related Interpretations.

FAIR VALUE OF FINANCIAL INVESTMENTS

The Company believes that the carrying amount of its financial instruments,
including debt, approximates fair value. Fair value is estimated based on quoted
market prices for similar instruments.

5. PATENT AND LICENSE AGREEMENTS

On December 3, 1987, DTM entered into a patent license agreement with the Board
of Regents of The University of Texas System, whereby DTM is licensed to make,
have made and sell products utilizing the selective laser sintering technology.
In consideration of rights granted in the license agreement, DTM issued 20,442
shares of its common stock to The University of Texas System.

The agreement provides for royalty payments in the amount of four percent of
DTM's net sales for products covered by the license agreement (gross receipts
net of commissions, returns, freight, discounts and sales taxes). Royalty
expense, included in cost of sales, was $552,000 in 1997, $676,000 in 1996 and
$424,000 in 1995.

7. FINANCING ARRANGEMENTS

Short-Term Borrowings

At December 31, 1997 and 1996, DTM had a total of $175,000 and $769,000,
respectively, of short-term debt outstanding under the terms of a financing
arrangement with a leasing company. The weighted average interest rates on
outstanding short-term borrowings were 15 and 20 percent at December 31, 1997
and 1996, respectively. The weighted average interest rates during 1997 and 1996
were 18 and 21 percent, respectively. The debt is collateralized by certain
equipment and accounts receivable.

The Company currently has a $2,000,000 line of credit with a bank, with no
amounts outstanding, due in April 1999, and guaranteed by BFGoodrich. At
December 31, 1996, DTM had lines of credit with three banks with combined
available borrowings of $12,200,000, of which $11,040,000 was outstanding, at an
interest rate of 6.2%. In May 1997, in connection with the Company's IPO, the
then outstanding borrowings were repaid.

Interest paid in connection with all of the above financing arrangements was
approximately $471,000 in 1997, $1,079,000 in 1996 and $451,000 in 1995. Amounts
paid to BFGoodrich were approximately $118,000 in 1997 and $153,000 in 1996.

8. UNUSUAL CHARGES

In connection with the 1997 IPO, the Company incurred a one-time non-cash stock
compensation expense of approximately $2,927,000 as a result of previously
outstanding stock appreciation rights converting into immediately vested stock
options at exercise prices below the market value of the common stock. This
charge was recorded in May 1997 (see Note 11).

During 1996, DTM attempted an IPO. However, due to market volatility and other
issues the IPO was postponed. The Company incurred approximately $752,000 of
legal, accounting and other professional services related to the unsuccessful
IPO which were expensed in the fourth quarter of 1996.

9. INCOME TAXES

During the period October 31, 1990 to May 21, 1997, DTM was included in the
consolidated federal tax return of BFGoodrich. The Company recorded the tax
benefit allocated to it by BFGoodrich during that period, which credited the
Company with a tax benefit approximating the benefit that BFGoodrich derived
from the consolidation of the Company. Such benefits were paid to the Company by
BFGoodrich on a current basis. As a result of the IPO, in May 1997, BFGoodrich's
ownership interest fell below 80 percent and such benefits are no longer
available to the Company. Based on the tax sharing agreement, if BFGoodrich
loses part of the tax benefit of any losses previously utilized or has to report
additional income as the result of a federal tax audit of DTM, DTM will be
required to reimburse BFGoodrich for any additional taxes paid.

DTM has net operating loss carryforwards totaling approximately $4,200,000 for
federal income tax purposes that were incurred from inception to October 31,
1990. These carryforwards expire in the years 2002 to 2004. Although available
to DTM, these carryforwards are subject to significant annual limitations due to
changes in DTM's ownership.

In addition, DTM has a net operating loss carryforward totaling approximately
$2,313,000 for federal income tax purposes that was incurred from May 1997 to
December 1997. This carryforward expires in the year 2012.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities of DTM for financial
reporting purposes and the amounts used for income tax purposes. Significant
components of the Company's deferred tax assets and liabilities as of December
31, 1997 and 1996 are as follows (in thousands):

taxable income of the applicable options holder and deductible by the Company
for federal and state income tax purposes. Any realized tax benefit arising from
exercised options in excess of the benefit previously recorded, as discussed in
Note 8, is credited to additional paid-in capital.

The operating lease for the Company's main facility matured in 1997. The Company
remains in this facility on a month-to-month basis while it negotiates a new
multi-year lease with the landlord.

As of December 31, 1997, the Company had purchase commitments for inventory
totaling approximately $3,425,000.

In the ordinary course of business, the Company becomes involved in legal
proceedings and claims. In one such instance, DTM filed an action in the United
States District Court for the Eastern District of Wisconsin in October 1995
against three parties who are operating an SLS System. DTM alleges that the
defendants willfully infringed a DTM patent. In June 1996, DTM amended its
lawsuit to also assert that one of the defendants breached an oral settlement
agreement. The Company seeks injunctive relief, damages and attorneys' fees. The
defendants have denied infringement and the existence of an oral settlement
agreement, and the defendants seek attorneys' fees. The defendants have also
asserted the affirmative defenses of patent invalidity, implied license, and
failure to mark patented articles, patent unenforceability and invalidity of the
oral settlement agreement. Discovery commenced in late 1995. In a subsequent
filing, one of the defendants also has asserted claims against DTM and
BFGoodrich for violation of state and federal antitrust laws. That defendant
seeks injunctive relief as well as damages and attorneys fees. In July 1997,
this court granted a temporary summary judgment that these particular defendants
had been given an implied license by DTM. DTM has filed an appeal of this
ruling. The contract claim against the defendants and

10. COMMITMENTS AND CONTINGENCIES (CONTINUED)

the antitrust claim against DTM and BFGoodrich remain for trial unless this case
is settled in the meantime. It is not possible at this time to predict the
outcome of these proceedings, although DTM and BFGoodrich have indicated that
they believe that the subsequent counter and cross claims for violation of
antitrust laws are without merit. However, a ruling unfavorable to the Company
could have a material adverse effect on the Company's business and financial
performance.

The Company has initiated patent infringement litigation in France, Germany and
Italy against a competitor and against one of that competitor's customers. The
Company also initiated patent infringement litigation in Japan against the
competitor's distributor in the Pacific Rim. In each of these cases, the Company
alleges that the competitor is selling rapid prototyping systems in Europe and
Japan that make unauthorized use of SLS technology covered by the European and
Japanese patents under which the Company has exclusive rights. The Company seeks
injunctive relief plus damages. It is anticipated that this litigation will be
pursued in conjunction with European and Japanese proceedings in which the
competitor has opposed the validity of those European and Japanese patents.
Hearings have begun in the German, French, Italian and Japanese lawsuits. It is
not possible at this time to predict the outcome of these proceedings.

DTM has been informed by this competitor that it has obtained the worldwide
right to enforce certain U.S. patents and that it may bring patent infringement
litigation against the Company in the U.S. courts. If the competitor does
initiate this litigation, the Company intends to vigorously oppose the action.
It is not possible at this time to predict the outcome of this possible action,
although the Company believes that it is not infringing or has valid defenses
and intends to contest this possible action vigorously, and that its SLS patents
around the world should be upheld. However, a ruling that would have the effect
of allowing the competitor to sell rapid prototyping systems in the U.S. could
have a material adverse effect on the Company's business and financial
performance.

A suit has been filed against the Company whereby certain plaintiffs claim that
material misstatements or omissions were made by the Company in connection with
the initial public offering of its stock. The plaintiffs have styled their
lawsuit as a class action, and they seek to represent the class of all
purchasers of the Company's stock from May 2, 1997 through June 18, 1997. On
June 18, 1997, the Company announced its anticipation that its results for the
quarter ending June 30, 1997 and the year ending December 31, 1997 would be
significantly below previous estimates. There has been no motion to certify the
proposed class to date. Plaintiffs seek rescission and damages. If the class
were certified, damages could include the proceeds of the Company's Initial
Public Offering ($22,818,000), plus interest. It is not possible at this time to
predict the outcome of this lawsuit, although the Company believes that the
allegations are without merit and intends to contest them vigorously. However, a
ruling unfavorable to the Company could have a material adverse effect on the
Company's business and financial performance.

11. COMMON STOCK AND OPTIONS

At December 31, 1997, the Company had two stock based compensation plans as
described below. The Company applies APB Opinion 25 and related interpretations
in accounting for its plans. Accordingly no compensation cost has been
recognized for the Company's stock based compensation plans, except for stock
options issued upon conversion by formula of stock appreciation rights effective
with the IPO in May 1997 at exercise prices below market value on the date of
conversion. Had compensation cost for the Company's two stock based compensation
plans been determined using the alternative accounting method based upon the
fair value prescribed by FASB Statement No. 123, the Company's pro forma net
loss for 1997 would have been $(8,048,000) and the Company's pro forma net loss
per common share for 1997 would have been $(1.60).

The fair value of each option grant is estimated on the date of grant for
repricing using the Black-Scholes option pricing model with the following
weighted-average assumptions for options granted or repriced in 1997:
amortization over the respective vesting periods; no dividends; expected lives
of four years; expected stock price volatility of approximately 60%; and risk
free interest rate of 6%. These pro forma results may not be representative of
that to be expected in future years.

A summary of the status of the Company's two stock option plans for 1997 is as

EQUITY APPRECIATION PLAN

In January 1995, the Board of Directors approved the DTM Corporation Equity
Appreciation Plan (the "SAR Plan"), which created 10,000,000 Phantom Stock
Units. Ten percent of the Phantom Stock Units were allocated for the issuance of
a like number of Phantom Stock Appreciation Rights ("SARs") under the SAR Plan
to eligible employees. Due to the terms and conditions of the SAR Plan, the SARs
or stock options outstanding thereunder were accounted for by the Company as
compensation expense immediately after the IPO date. The amount of compensation
expense so recognized was equal to the number of SARs or stock options
outstanding multiplied by the difference between the exercise price of each SAR
or stock option and the value of each SAR or stock option at the date of the
Change in Control. Upon the closing of the IPO, the Company recognized a non-
cash charge (compensation) of approximately $2.9 million to record the
appreciation in value of the SARs. The Company has reserved 553,150 shares of
Common Stock for future issuance under the SAR Plan. The SARs or stock options
granted to the Participants will become exercisable by the Participants for a
period of 10 years from the date on which the SARs or stock options are granted.
As of December 31, 1995, 1996 and 1997, there were 998,000, 840,500 and -0- SARs
outstanding, respectively. The SARs granted during 1995 were granted at a fair
value of $1.40 per SAR. During 1996, 29,000 SARs were granted at a fair value of
$9.22 per SAR. In addition, 185,000 SARs were forfeited in 1996. During 1997,
but before the IPO date, the Company granted an additional 157,500 SARs at a
fair value of $8.50 per SAR and 4,500 SARs were forfeited. The SARs granted in
1995, 1996, 1997 and subsequent to December 31, 1996 were converted to stock
options with exercise prices of approximately $2.23 per share, $13.53 per share
and $14.67 per share, respectively.

KEY EMPLOYEE STOCK OPTION PLAN

In January 1996, the Company's Board of Directors approved a DTM Corporation
Stock Option Plan (the "Option Plan"). Under the Option Plan, the Company set
aside 357,755 shares which may be awarded to key employees, as selected by
management and approved by the Compensation Committee of the Board of Directors
(the "Committee") through stock options, stock appreciation rights, limited
stock appreciation rights, restricted stock, performance shares, or other awards
as determined by the Committee. In the case of stock option awards, the option
price per share may not be less than the fair market value of a share on the
date the option is granted. Options granted under the Option Plan will vest in
three separate installments with 35 percent of the options granted becoming
exercisable on the first anniversary date of the option grant, 35 percent
becoming exercisable on the next succeeding anniversary date and 30 percent
becoming exercisable on the next succeeding anniversary date. Options will be
exercisable for a period of no more than 10 years from the date of grant. The
term of the Option Plan is five years unless terminated earlier by the Board of
Directors. In 1997, the Company granted 96,500 options at an exercise price of
$8.03. In January 1998, the Company granted 115,000 options at an exercise price
of $2.00 per share.

1998 STOCK OPTION PLAN

In January 1998, the Company's Board of Directors approved a DTM Corporation
1998 Stock Option Plan (the "1998 Stock Option Plan"), subject to Shareholder
approval at the 1998 Annual Meeting. Under the 1998 Stock Option Plan, the
Company set aside 300,000 shares which may be awarded to any employee, as
selected by management and approved by the Committee, through stock options,
stock appreciation rights, limited stock appreciation rights, restricted stock,
performance shares, or other awards as determined by the Committee. In case of
stock option awards, the option price per share may not be less than the fair
market value of a share on the date the option is granted. Options granted under
the 1998 Stock Option Plan will vest in three separate installments with 35
percent of the options granted becoming exercisable on the first anniversary
date of the grant, 35 percent becoming exercisable on the next succeeding
anniversary date and 30 percent becoming exercisable on the next succeeding
anniversary date. The term of the 1998 Stock Option Plan is five years unless
terminated earlier by the Board of Directors.

12. MANAGEMENT INCENTIVE PLAN

In January 1996, the Company's Board of Directors approved a DTM Corporation
Management Incentive Plan (the "MIP Plan"). The MIP Plan provides for the grant
of incentive compensation to key management employees who have the potential to
positively influence the performance of the Company as a reward for levels of
performance above the ordinary performance standards compensated by base salary.
Under the MIP Plan, each participant is assigned a "cash bonus target" of 20 to
50 percent of base salary and the Compensation Committee of the Board of
Directors creates personal and corporate performance targets, as well as minimum
thresholds. If the minimum thresholds are met, the bonus payable will be between
50 and 150 percent of the participant's cash bonus target. No expense was
recognized in connection with the MIP Plan in 1997 or 1996.

13. GEOGRAPHIC AND CUSTOMER INFORMATION

The Company and its subsidiary, located in Germany, operate in one industry
segment: the development, manufacturing and service of SLS systems and related
products. Operations outside of the United States consist principally of sales,
marketing and customer support. Transfers between geographic areas are accounted
for at amounts which are generally above cost and consistent with the rules and
regulations of governing tax authorities. Such transfers are eliminated in the
consolidated financial statements. Identifiable assets are those assets that can
be directly associated with a particular geographic area. The following is a
summary of operations within each geographic area (in thousands):
