                                     PART I


ITEM 1.  BUSINESS.
         --------

       GSE Systems, Inc. ("GSE Systems", "GSE" or the "Company") develops and
delivers business and technology solutions by applying process control,
simulation software, systems and services to the energy, process and
manufacturing industries worldwide. The Company's solutions and services assist
customers in improving quality, safety and throughput; reducing operating
expenses; and enhancing overall productivity.

       The Company's products are used in over 700 applications, representing
over 250 customers in 44 countries, in the following industries: specialty
chemical, food & beverage, pharmaceutical, and fossil and nuclear power
generation.

Recent Developments.

        Power Simulation Business

       The Company's Power Simulation Business Unit continued to show profitable
performance during the year, as the Company maintained its dominant market
position in the nuclear power simulation industry. Utilizing its technical and
project management strengths, the business unit expanded its focus to include
the fossil power market and an emphasis was placed on developing the tools
necessary to exploit the fossil simulation marketplace. As a result, the Company
was successful in several competitive bids for fossil simulators, including a
multi-million dollar order for a full scope fossil simulator in India. The
Company sees this as a growing market segment for the power business. In
addition, the deregulation of the electric power industry has increased the
importance of efficient and reliable operations of power stations. The use of
simulation to address these issues has resulted in new opportunities for GSE to
improve the simulation fidelity of existing simulators and the supply of new
simulators around the world. While GSE simulators are primarily utilized for
power plant operator training, the uses are expanding to include engineering,
plant modification studies, and operating efficiency improvements for both
nuclear and fossil utilities.

        Process Control Business

       GSE's Process Control business experienced sluggish performance during
the first half of the year. After spending extensively in 1998 and the first
half of 1999 on upgrading their process control systems to deal with the Y2K
date issue concerns, customer spending on additional investments in their
process control systems remained depressed in the first half of 2000. The entire
process control industry was affected by this trend, as well as other economic
factors in the Chemical Industry which reduced overall capital spending on
process control systems. Accordingly, the Company implemented a restructuring
plan to bring the operating costs in line with lower revenue projections.
Actions taken included personnel reductions, the outsourcing of Process'
manufacturing and assembly operations, and the sale of Process' unprofitable
European operations based in Belgium to Newton Integrated Services, B.V. of
Bergen Op Zoom, Netherlands. As part of the sale, Newton, which is an
engineering company that focuses on electrical, mechanical and control system
services, entered into a marketing agreement with Process to be the European
distributor of the D/3 product line. The Process Business Unit (net of its
VirtualPlant(TM) activities) saw an improvement to operating income in the third
and fourth quarters of the year as a result of the restructuring.

        VirtualPlant Strategy

       During 2000, the Company continued to develop and invest extensively in
its VirtualPlant business and marketing strategy that was introduced in 1999.
VirtualPlant combined the benefits of real-time simulation with control systems
to create a real-time representation of an operating plant. VirtualPlant also
allowed a customer to create an environment for simulation-enhanced
experimentation, thereby reducing the amount of physical experimentation
necessary to achieve an optimal design result for a new process product.

       A significant step in implementing the VirtualPlant strategy was the
Company's participation in the February 2000 founding of Avantium International
B.V. ("Avantium"), a Netherlands-based high technology company that employs
high-speed experimentation and simulation technologies in contract research and
development in the area of new product development and process chemistry. GSE
licensed certain of its simulation software products to Avantium in exchange for
Avantium preferred and common stock. At December 31, 2000 the Company held
approximately 10.4% of Avantium's outstanding preferred and common stock. GSE
was to provide the basis for the informatics system that would automate and
maximize Avantium's lab environment, and utilize its core simulation
technologies to assist in the optimization of experimentation as well as
analysis of the resulting data.

       In addition, the Company received a $2.9 million contract from Avantium
to make certain improvements and enhancements to the software licensed to
Avantium. In the fourth quarter, GSE delivered Virtual Laboratory workstations
to Avantium's Laboratory in the Netherlands and to the Technical University in
Delft. These Virtual Labs use GSE's D/3 Control System(TM), VPBatch(TM)
recipe/experiment management software, BatchCAD and SimSuite Pro(TM) simulation
software in combination with high-speed experimentation robotic equipment to
accomplish high throughput catalyst development.

     In  early  2000,  GSE's  Board  of  Directors   acknowledged  that  outside
investment was required to support the development of the VirtualPlant  business
since the Company's cash flow was insufficient by itself.  After the Company was
unsuccessful  in  attracting  the needed  capital with terms  acceptable  to the
Board, the Board made the decision to sell the  VirtualPlant  assets to Avantium
in exchange for Avantium stock, thus eliminating the cash burden on the Company.

       The asset sale closed on March 6, 2001 and included certain fixed assets
of the Company, intellectual property (including BatchCAD and BatchWizard
software products), and the employment of certain personnel in both the US and
the UK. GSE received 8% of Avantium's stock, thus increasing its holdings in
Avantium to approximately 18%. GSE retains one seat on the supervisory board of
Avantium. Also, the Company licensed their process control and simulation
software ("GSE Process Software") exclusively to Avantium for the R&D market.
This licensing arrangement includes free updates to the GSE Process Software. In
return, GSE received a royalty-free license to use any upgrades of the GSE
Process Software produced by Avantium in the manufacturing market. GSE also
received a royalty-free license to use and produce upgrades of the BatchWizard
Software owned by Avantium in the manufacturing market. Avantium and GSE will
continue to work together in the marketplace and in product development so that
common clients will be able to use Avantium's VirtualPlant technology to develop
scalable products that will fit together at the manufacturing level with GSE's
process control and simulation products, thus speeding up market introduction
and reducing the overall life cycle costs.

        Continued Research and Development

       Throughout the year, GSE continued to invest in its core products of D/3
Distributed Control System and Power Simulation technology. The Company enhanced
the capabilities of the D/3 to communicate with more I/O families, by adding a
connection to the Allen Bradley ControlNet data highway, and continued the
development of the next release of the D/3, version 10.2. GSE also expanded the
features of Microsoft Windows NT(R) within the products, completing the
development of its VPbatch product, which is the Windows NT version of its
FlexBatch Recipe and Process management software.

       Continuing its history of bringing leading edge technology to the
simulation market, the Company has also started converting its Power Simulation
tools to be able to use Java technology to take better advantage of the internet
to provide remote training to customers.

Background.

       GSE Systems was formed on April 13, 1994, by ManTech International
Corporation ("ManTech"), GP Strategies Corporation ("GP Strategies") and its
affiliates, General Physics Corporation and SGLG, Inc., and Vattenfall AB to
consolidate the simulation and related businesses of their affiliates, GSE Power
Systems, Inc. ("Power Systems" and formerly known as "Simulation, Systems &
Services Technologies Company" or "S3 Technologies"), GP International
Engineering & Simulation, Inc. ("GPI") and GSE Power Systems AB ("Power Systems
AB" and formerly known as "EuroSim AB"). On December 30, 1994, GSE Systems
expanded into the process control automation and supply chain management
consulting industry through its acquisition of the process systems division of
Texas Instruments Incorporated, which the Company operates as GSE Process
Solutions, Inc. ("Process Solutions").

       In April 1996, the Company aligned its operating groups into three
strategic business units to better serve its then primary vertical markets -
Power, Process and Oil & Gas. The realignment allowed the Company to focus on
providing all of its technologies to these markets, while addressing the
specific needs of each market and delivering industry specific solutions.

       In May 1996, the Company acquired Erudite Software & Consulting, Inc.
("Erudite"), a regional provider of client/server technology, custom application
software development,training services,  hardware/software sales,
and network design and implementation services. The acquisition was made to
facilitate the Company's efforts to enter the client/server information
technology solutions market. Erudite was subsequently combined with a small
pre-existing consulting group within the Company to form the Company's Business
Systems business unit.

       In December 1997, the Company acquired 100% of the outstanding common
stock of J.L. Ryan, Inc. ("Ryan"), a provider of engineering modifications and
upgrade services to the power plant simulation market. The combination of the
Company's pre-existing technology with the technical staff of the acquired Ryan
business positioned the Company to be more competitive for modifications and
upgrade services projects within the nuclear simulation market.

       After incurring substantial losses in 1997, management decided to divest
the Company's unprofitable business units and concentrate its resources on its
core businesses, Power Systems and Process Solutions. Accordingly, in April
1998, the Company sold substantially all of the assets of Erudite to Keane, Inc.
and in November 1998, the Company divested certain assets of the Oil & Gas
business unit to Valmet Automation (USA), Inc. See Note 3, Acquisitions and
dispositions, in the " Notes to the Consolidated Financial Statements" for a
discussion of these transactions.

       In April 1999, the Company acquired certain assets and employed the
associates of BatchCAD Limited. With this acquisition, the Company gained a
presence in the United Kingdom, with an office in Hexham, England, that was to
provide the baseline for future expansion in the region. In addition, the
BatchCAD product was a key element in the Company's VirtualPlant business and
marketing strategy.

       See the prior section "Recent Developments" for a discussion of GSE's
development of its VirtualPlant strategy in 2000 and the sale of the
VirtualPlant business to Avantium International B.V. in March 2001.

Business Strategy.

       GSE Systems combines real-time control automation, real-time simulation
and application engineering for true problem solving techniques and solutions.
The Company believes this provides a technological advantage which, when
combined with its focused efforts on targeted industry markets and defined
application solution approach, allows its staff to assess, define, develop, and
apply innovative solutions that meet the current and future industry-specific
needs of its customers.

       Low cost, high quality products is the mantra of the
manufacturing business. GSE believes deregulation in the energy sector will
result in the same mantra for the power industry, thus resulting in an increase
in the use of high fidelity simulation in the fossil power market. In the past,
that market segment was characterized by simplified simulation solutions used
mainly to teach operators the use of new distributed control systems. With
deregulation, the power companies are realizing that sophisticated simulation
models will help teach the operators how to improve plant efficiency, avoid
unscheduled outages and maximize production in a competitive power market.

       The strategy of combining simulation and control technology to help
customers optimize plant performance in the manufacturing space is  a
viable strategy. The Company proved its value in the R&D market space through
its VirtualPlant business. The Company will work on exploiting the strategy in
the manufacturing market space. The combination of our technologies will provide
a virtual representation of our customers' ideal or existing plant that can be
used for model reference control and assist management of the business with
determining the optimal approach to operating the plant. In the energy sector we
will provide energy managers with the ability to reduce operating costs by
gaining more productivity through training, plant information, asset management,
security and plant design and optimization.

       The Company will also continue to use our process control and batch and
recipe management systems to optimize production in the chemical, pharmaceutical
and food & beverage industries by improving process chemistry in correlation
with process flow throughout the plant. These tools assist in "brand" transition
to quickly meet market demands, and technology transfer between locations. The
tools help the customer understand and manage scheduling and equipment
utilization to optimize plant throughput.

       The Company believes that GSE Systems can partner with customers to help
provide them with cost-effective solutions for problems associated with
simulation and control, which would allow its customers to focus their resources
on their strengths.

power plant simulation.

       As the Microsoft Windows NT(R) operating environment continues to evolve,
the Company has continued the migration of its products to this platform in such
a way as to assure current customers' legacy applications will function properly
while at the same time offering the advantages of the new technology. Although
the Company uses open standards for its products, the Company's standard system
configurations are based on the proprietary technology and know-how necessary to
meet the requirements of its customers in the controls and simulation markets.

       The Company's business model is based on software licensing and
value-added services, as well as hardware sales. Because this model is based
primarily on software and value-added services, the Company believes it can
maintain its business model in an environment of rapidly decreasing hardware
costs.

       In the Process Business Unit, the flagship product is a Distributed
Control System ("DCS") product, known as the D/3 DCS(TM) that is highly flexible
and open. This product is a real-time system, which uses multiple process
control modules to monitor, measure, and automatically control variables in both
continuous and complex batch processes, as well as form the platform for
plant-wide information for use by operators, engineers and management.

Netherlands, Spain, the Czech Republic, India, South Africa, Mexico, Argentina,
Taiwan, Korea, Japan and the People's Republic of China.

Product Development.

       In 2000, the Company completed the development of its VPbatch product
which is the Windows NT version of its FlexBatch Recipe and Process Management
software, and completed the development of version 10.2 (released in December)
of the Company's D/3 Distributed Control System. In addition, the Company
continued development initiatives to improve the product ease of use of its
process simulation products. For the years ended December 31, 2000, 1999 and
1998, gross research and product development expenditures for the Company were
$3.6 million, $5.4 million, and $4.3 million, respectively. Capitalized software
development costs totaled $1.9 million, $2.5 million, and $2.3 million for the
years ended December 31, 2000, 1999 and 1998. See Note 2, Summary of significant
accounting policies, in the "Notes to Consolidated Financial Statements" for a
discussion of the Company's policy regarding capitalization of software
development costs.

       The Company also continued to develop simulation code generation tools
applicable to the growing fossil power industry. These tools bring the high
fidelity modeling with easy to use graphical interfaces to quickly build models
for fossil plant simulators. This reduces the cost of production to allow the
Company to be price competitive in the industry.

Industries Served.

       The following chart illustrates the approximate percentage of the
Company's 2000, 1999, and 1998 revenues, respectively, attributable to each of
the major industries served by the Company:



                         

                                    2000         1999        1998

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



Contract Backlog.

       The Company does not reflect an order in backlog until it has received a
contract that specifies the terms and milestone delivery dates. As of December
31, 2000, the Company's aggregate contract backlog totaled approximately $23
million.





Employees.

       As of December 31, 2000, the Company had 303 employees, a 26% decrease
from December 1999. The reductions were primarily associated with the Process
Controls Business Unit restructuring as discussed in the "Recent Developments"
section, above.

Segment Information.

       See Note 18, Segment information, in the "Notes to Consolidated Financial
Statements" for a discussion of the Company's business segments.

RISK FACTORS.

Fluctuations in Quarterly Operating Results.

       The Company's operating results have fluctuated in the past and may
fluctuate significantly in the future as a result of a variety of factors,
including purchasing patterns, timing of new products and enhancements by the
Company and its competitors, and fluctuating foreign economic conditions. Since
the Company's expense levels are based in part on its expectations as to future
revenues, the Company may be unable to adjust spending in a timely manner to
compensate for any revenue shortfall and such revenue shortfalls would likely
have a disproportionate adverse effect on operating results. The Company
believes that these factors may cause the market price for its common stock to
fluctuate, perhaps significantly. In addition, in recent years the stock market
in general, and the shares of technology companies in particular, have
experienced extreme price fluctuations. The Company's common stock has also
experienced a relatively low trading volume, making it further susceptible to
extreme price fluctuations.

International Sales and Operations.

       Sales of products and the provision of services to end users outside the
United States accounted for approximately 52 % of the Company's consolidated
revenues in 2000. The Company anticipates that international sales and services
will continue to account for a significant portion of its revenues in the
foreseeable future. As a result, the Company may be subject to certain risks,
including risks associated with the application and imposition of protective
legislation and regulations relating to import or export (including export of
high technology products) or otherwise resulting from trade or foreign policy
and risks associated with exchange rate fluctuations. Additional risks include
potentially adverse tax consequences, tariffs, quotas and other barriers,
potential difficulties involving the Company's strategic alliances and managing
foreign sales agents or representatives and potential difficulties in accounts
receivable collection. The Company currently sells products and provides
services to customers in emerging market economies such as Russia, Ukraine,
Bulgaria, and the Czech Republic. The Company has taken steps designed to reduce
the additional risks associated with doing business in these countries, but the
Company believes that such risks may still exist and include, among others,
general political and economic instability, lack of currency convertibility, as
well as uncertainty with respect to the efficacy of applicable legal systems.
There can be no assurance that these and other factors will not have a material
adverse effect on the Company's business, financial condition or results of
operations. Furthermore, the Company's ability to expand its business into
certain emerging international markets is dependent, in part, on the ability of
its customers to obtain financing.

Revenues in the Nuclear Power Industry.

       The Company will continue to derive a significant portion of its revenues
from customers in the nuclear power industry, particularly the international
nuclear power industry, for the foreseeable future. The Company's ability to
supply nuclear power plant simulators and related products and services is
dependent on the continued operation of nuclear power plants and, to a lesser
extent, on the construction of new nuclear power plants. A wide range of factors
affect the continued operation and construction of nuclear power plants,
including the political and regulatory environment, the availability and cost of
alternative means of power generation, the occurrence of future nuclear
incidents, general economic conditions and the ability of customers to obtain
adequate financing.

Revenues in the Chemicals Industry.

       The Company derives a portion of its revenues from companies in the
chemicals industry. Accordingly, the Company's future performance is dependent
to a certain extent upon the demand for the Company's products by customers in
the chemical industry. The Company's revenues may be subject to period-to-period
fluctuations as a consequence of industry cycles, as well as general domestic
and foreign economic conditions and other factors affecting spending by
companies in the Company's target process industries. There can be no assurance
that such factors will not have a material adverse effect on the Company's
business, operating results and financial condition.

Product Development and Technological Change.

       The Company believes that its success will depend in large part on its
ability to maintain and enhance its current product line, develop new products,
maintain technological competitiveness and meet an expanding range of customer
needs. The Company's product development activities are aimed at the development
and expansion of its library of software modeling tools, the improvement of its
display systems and workstation technologies, and the advancement and upgrading
of its simulation and process control technologies. The life cycles for software
modeling tools, display system software, process control and simulation
technologies are variable and largely determined by competitive pressures.
Consequently, the Company will need to continue to make significant investments
in research and development to enhance and expand its capabilities in these
areas and to maintain its competitive advantage.

       The Company's products are offered in markets affected by technological
change and emerging standards that are influenced by customer preferences. The
Company has expended significant resources in developing versions of its core
products that operate in the increasingly popular Windows NT(R) environment;
however, there can be no assurance of customer acceptance of these Windows
NT(R)-based products or that these products will be competitive with products
offered by the Company's competitors. Although the Company believes that no
significant trends to migrate to other operating platforms currently affect the
markets for the Company's products, there can be no assurance that customers
will not require compatibility with such other operating platforms in the
future.

Intellectual Property Rights.

       Although the Company believes that factors such as the technological and
creative skills of its personnel, new product developments, frequent product
enhancements and reliable product maintenance are important to establishing and
maintaining a technological leadership position, the Company's business depends,
in part, on its intellectual property rights in its proprietary technology and
information. The Company relies upon a combination of trade secret, copyright,
patent and trademark law, contractual arrangements and technical means to
protect its intellectual property rights. The Company generally enters into
confidentiality agreements with its employees, consultants, joint venture and
alliance partners, customers and other third parties that are granted access to
its proprietary information, and generally limits access to and distribution of
its proprietary information. There can be no assurance, however, that the
Company has protected or will be able to protect its proprietary technology and
information adequately, that the unauthorized disclosure or use of the Company's
proprietary information will be prevented, that others have not or will not
develop similar technology or information independently, or, to the extent the
Company owns patents, that others have not or will not be able to design around
those patents. Furthermore, the laws of certain countries in which the Company's
products are sold do not protect the Company's products and intellectual
property rights to the same extent as the laws of the United States.

Competition.

       The Company's businesses operate in highly competitive environments with
both domestic and foreign competitors, many of whom have substantially greater
financial, marketing and other resources than the Company. The principal factors
affecting competition include price, technological proficiency, ease of system
configuration, product reliability, applications expertise, engineering support,
local presence and financial stability. The Company believes that competition in
the simulation and process automation fields may further intensify in the future
as a result of advances in technology, consolidations and/or strategic alliances
among competitors, increased costs required to develop new technology and the
increasing importance of software content in systems and products. The Company
believes that its technology leadership, experience, ability to provide a wide
variety of solutions, product support and related services, open architecture
and international alliances will allow it to compete effectively in these
markets. As the Company's business has a significant international component,
changes in the value of the dollar could adversely affect the Company's ability
to compete internationally.

       Additionally, GSE Systems' operations are dependent on the efforts of its
technical personnel and its senior management. Thus, recruiting and retaining
capable personnel, particularly engineers, computer scientists and other
personnel with expertise in computer software and hardware, as well as
particular customer processes, are critical to the future performance of the
Company. Competition for qualified technical and management personnel is
substantial.

Legal Liability.

       The Company's business could expose it to third party claims with respect
to product, environmental and other similar liabilities. Although the Company
has sought to protect itself from these potential liabilities through a variety
of legal and contractual provisions as well as through liability insurance, the
effectiveness of such protections has not been fully tested. The failure or
malfunction of one of the Company's systems or devices could create potential
liability for substantial monetary damages and environmental cleanup costs. Such
damages or claims could exceed the applicable coverage of the Company's
insurance. Although management has no knowledge of material liability claims
against the Company to date, such potential future claims could have a material
adverse effect on the business or financial condition of the Company. Certain of
the Company's products and services are used by the nuclear power industry. The
Company believes that it does not have significant liability exposure associated
with such use, as nearly all such products and services relate to training.
Although the Company's contracts for such products and services typically
contain provisions designed to protect the Company from potential liabilities
associated with such use, there can be no assurance that the Company would not
be materially adversely affected by claims or actions which may potentially
arise.

Influence of Affiliate Stockholders.

       As of the date of this report, certain directors, executive officers and
other parties that are affiliates of the Company beneficially own approximately
43% of the common stock of the Company. If these stockholders vote together as a
group, they will be able to exert significant influence on the business and
affairs of the Company, including the election of individuals to the Company's
Board of Directors, and the outcome of actions that require stockholder
approval.



ITEM 2. PROPERTIES.

     The  Company's  Power  business  unit is  headquartered  in a  facility  in
Columbia,  Maryland  (approximately  53,000  square  feet) which also houses the
Company's  corporate  headquarters  offices and support  functions.  The Process
business  unit is  located  in a  34,000  square  foot  facility  in  Baltimore,
Maryland. The leases for both of these facilities expire in 2008.

     In  addition,  the Company  leases  office space  domestically  in Alabama,
Georgia,  Louisiana,   Texas,  Pennsylvania,   North  and  South  Carolina,  and
internationally  in  Japan,   Sweden,  and  Taiwan.  The  Company  leases  these
facilities for terms ending  between 2001 and 2002.  During 1999, as part of the
wind down of the Oil & Gas business unit, the Company's  facilities in Singapore
and Korea were closed.  In 2000, the Company's lease for its Belgian  operations
was transferred in the sale of its Belgian subsidiary, and the leases for its UK
operations were transferred to Avantium as part of the VirtualPlant asset sale
in March, 2001.


ITEM 3.  LEGAL PROCEEDINGS.
         -----------------

       The Company is from time to time involved in legal proceedings incidental
to the conduct of its business. The Company currently is not a party to legal
proceedings which, in the opinion of management, are likely to have a material
adverse effect on the Company's business, financial condition or results of
operations.


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

       No matter was submitted to a vote of security holders during the quarter
ended December 31, 2000.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.
         ---------------------------------------------------------------------

       The following table sets forth, for the periods indicated, the high and
low sale prices for the Company's common stock reported by the American Stock
Exchange:

Fourth                 $ 4 1/4            $ 3



        In January 1999, the Company's common stock was approved for listing on
the American Stock Exchange, where it now trades under the symbol "GVP".
Previously, the Company's common stock had traded on the NASDAQ National Market
System under the symbol "GSES".

       There were approximately 35 holders of record of the common stock as of
March 15, 2001. Based upon information available to it, the Company believes
there are approximately 700 beneficial holders of the common stock. The Company
has never declared or paid a cash dividend on its common stock. The Company
currently intends to retain future earnings to finance the growth and
development of its business and, therefore, does not anticipate paying any cash
dividends in the foreseeable future.

       The Company believes factors such as quarterly fluctuations in results of
operations and announcements of new products by the Company or by its
competitors may cause the market price of the common stock to fluctuate, perhaps
significantly. In addition, in recent years the stock market in general, and the
shares of technology companies in particular, have experienced extreme price
fluctuations. The Company's common stock has also experienced a relatively low
trading volume, making it further susceptible to extreme price fluctuations.
These factors may adversely affect the market price of the Company's common
stock.





ITEM 6.         SELECTED FINANCIAL DATA.

       Historical consolidated results of operations and balance sheet data
presented below, have been derived from the historical financial statements of
the Company. The Company disposed of substantially all of the assets of its

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

       During the year ended December 31, 2000, the Company incurred significant
operating losses which resulted in non-compliance with certain financial
covenants included in the Company's bank credit facility. The Company has
obtained a waiver of the financial covenant defaults as well as certain covenant
modifications to help position the Company for future compliance. Nevertheless,
future compliance will depend upon achieving significantly improved operating
results during 2001 and beyond.

       Management has undertaken a number of initiatives during 2000 and 2001 to
improve operating results and cash flows including:

(i)  The  restructuring  of the Process business unit to reduce operating costs.
     Actions  taken  in  2000  included  (a)  personnel   reductions;   (b)  the
     outsourcing of Process' manufacturing and assembly operations;  and (c) the
     sale of  Process'  unprofitable  Belgian  subsidiary  to Newton  Integrated
     Services,  B.V. of the Netherlands.  Included in operating  results for the
     year ended December 31, 2000 are revenues of $1.5 million and operating
     losses, before allocation of corporate expenses, of $308,000 attributable
     to GSE Process Solutions N.V.

(ii) The sale of the Company's  VirtualPlant  business to Avantium International
     B.V.  ("Avantium").  The asset  sale  closed on March 6, 2001 and  included
     certain  fixed  assets  of the  Company,  intellectual  property,  and  the
     employment  of certain  personnel  in both the US and UK by  Avantium.  GSE
     received 8% of Avantium's  stock,  thus increasing its holdings in Avantium
     to  approximately  18%. For the year ended December 31, 2000, the Company's
     VirtualPlant  business  had  revenues  of $6.1  million and an operating
     loss before allocation of corporate expenses of $3.4 million.

(iii) ManTech International  Corporation  ("Mantech")  has  agreed  to allow the
     Company's  bank to draw upon  ManTech's $1.8 million letter of credit which
     supports the Company's credit  facility,  thus paying down a portion of the
     Company's  bank debt, in exchange for additional  subordinated  debt in the
     Company.  (See  Note  16,  Related  party  transations,  in the  "Notes  to
     Consolidated Financial Statements.")

     Management  believes the initiatives  undertaken will enable the Company to
maintain compliance with the revised bank financial covenants as well as provide
sufficient  cash flow to meet the  Company's  obligations  as they  become  due.
However,  if the  initiatives  are not  successful  or if there  are  unforeseen
decreases in demand for the Company's  products or increases in working  capital
needs the  Company may be unable to meet the revised  bank  financial  covenants
and/or to generate  sufficient  cash flows from  operations.  In such case,  the
Company  will be  required  to  obtain  additional  covenant  modifications  and
additional  sources of funding.  There can be no  assurance  that such  covenant
modifications or funding, if needed, will be available.





Results of Operations.

       The following table sets forth the results of operations for the periods
presented expressed in thousands of dollars and as a percentage of revenues.

 Comparison of 2000 to 1999.

     Contract  Revenue.  Total  contract  revenue  was $55.7  million  and $66.7
million for the years ended December 31, 2000 and 1999, respectively.

       The Process business unit's revenues decreased by $9.4 million, or 27.2%,
to $25.2 million in 2000 from $34.6 million in 1999. Beginning in the second
half of 1999, the Process business unit experienced an order slowdown as
customers postponed additional investments in their process control systems,
pending the resolution of Y2K date issue concerns. This order slowdown continued
into 2000 as customers either spent their capital funding on other projects
(since so much money was spent on upgrading the process control systems in
1998-1999) or were faced with tougher economic conditions in 2000 (especially
customers in the chemical industry) which forced them to cut back on their
overall capital spending. Included in the 2000 Process revenue was $2.9 million
from the sale of licenses for five of GSE's software products to Avantium
International B.V. ("Avantium") in February, including the object and source
codes, in exchange for an equity interest in Avantium. See Note 4, Investment in
Avantium International B.V., in the "Notes to Consolidated Financial Statements"
for a discussion of this transaction.

       The Power business unit revenue decreased by $1.6 million, or 5.0%, to
$30.5 million in 2000 from $32.1 million in 1999, primarily due to lower nuclear
simulation upgrade orders from Japanese and Eastern European customers.

       Gross Profit. In large part due to the lower revenues in 2000, gross
profit declined to $14.9 million in 2000 (26.7% of revenue) from $25.1 million
in 1999 (37.6% of revenue). The decrease in gross profit as a percentage of
revenue is due to the following:

o    In 1999, the Process  business was benefiting from customer  concerns about
     the Y2K  issue and their  efforts  to  upgrade  their  D/3  systems  to Y2K
     compliant  versions.  Upgrade  projects  typically  have less  hardware and
     instrumentation  components  (lower  margined  items as these are typically
     "pass-through" purchases) and more license fees and application engineering
     work  which  have  higher  margins.  In 2000,  a higher  percentage  of the
     revenues were generated through maintenance,  time and material, spares and
     training which have lower margins than the upgrade projects.
o    Capitalized  software  amortization  increased from $1.8 million in 1999 to
     $2.2  million  in 2000  due to the  completion  in 1999 of the NT  platform
     conversion of the D/3 Distributed  Control  System,  the release of version
     10.1 of the D/3  product  in July  2000,  and  the  completion  of  several
     upgrades to the SimSuite Pro  Software in July 2000 and the  initiation  of
     the amortization of the related capitalized costs.
o    A $710,000 provision was recorded in December  2000 for certain  Process
     inventory to adjust its carrying value to net realizable value.

       Selling, General and Administrative Expenses. Selling, general and
administrative ("SG&A") expenses totaled $17.9 million in 2000 (32.1% of
revenues), a 20.8% decrease from 1999 expenses of $22.6 million (34.0% of
revenues). Other than changes in research and developments costs, which
decreased $1.2 million and are discussed below, the decrease in SG&A is
attributable to:

o    Fewer  sales  and  marketing  personnel  and  travel  costs in the  Process
     business  unit due to the  restructuring  of this  business.
o    Lower sales commissions due to lower Process business unit orders.
o    A reduction in corporate personnel.
o    The completion in 1999 of the Company's internal Y2K compliance program for
     which an outside consultant was utilized as project manager.
o    A reduction in recruiting and relocation costs of newly hired personnel.
o    The  completion  in 1999 of the  amortization  of the cost of the  warrants
     issued to ManTech and GP Strategies in 1998 in  consideration of guarantees
     issued by these companies for GSE's credit facility.

       These reductions were somewhat offset by the initiation of a marketing
program in 2000 which was designed to promote the benefits of VirtualPlant, and
the products and services associated with the Company's affiliation with
Avantium, to major customers around the world.

        Gross research and product development expenditures were $3.6 million
(6.5% of revenue) and $5.4 million (8.1% of revenue) for the years ended
December 31, 2000 and 1999, respectively. Of these expenditures, $1.9 million in
2000 and $2.5 million in 1999 were capitalized. Thus, net research and
development ("R&D") costs included in selling, general and administrative
expenses were $1.7 million and $2.9 million during the years ended December 31,
2000 and 1999, respectively. The reduction in R&D spending reflects the
completion of the conversion of Process' D/3 Distributed Control System to the
Microsoft Windows NT platform (Version 10.0, which introduced the new platform,
was released in October 1999) and a reduction in personnel as part of the
Process business restructuring.

       In 2000, the Company completed the development of its VPbatch product,
which is the Windows NT version of its FlexBatch Recipe and Process Management
software, and completed the development of version 10.2 (released in December)
of the Company's D/3 Distributed Control System. In addition, the Company
continued development initiatives to improve the product ease of use of its
process simulation products and to create a set of software simulation tools for
fossil power utilities.

       Depreciation and Amortization. Depreciation expense amounted to $1.2
million and $1.3 million during the years ended December 31, 2000 and 1999,
respectively.

       Amortization of goodwill was $528,000 and $388,000 during the years ended
December 31, 2000 and 1999, respectively. The increase in amortization reflects
the increase in goodwill due to payments made for contingent consideration for
prior year acquisitions.

       Operating Income (Loss). The Company incurred an operating loss of $4.7
million (8.4% of revenue) for the year ended December 31, 2000, compared with
operating income totaling $744,000 (1.1% of revenue) in 1999. The decrease in
operating income (loss) reflects the lower revenues in 2000 coupled with the
reduction in Process gross margin percent due to product mix as discussed above,
the increase in capitalized software amortization in 2000, the provision for
write-down of Process inventory and the investments made by the Company in
developing its VirtualPlant marketing and business strategy.

       Loss on Sale of Assets. The loss on sale of assets in 2000 reflects the
net pre-tax loss realized on the disposition of GSE Process Solutions NV, the
Company's Belgian subsidiary in the fourth quarter. This sale and related loss
is described more fully under Note 3, Acquisitions and dispositions, in the
"Notes to Consolidated Financial Statements".

     Interest Expense,  net. Interest expense increased to $687,000 in 2000 from
$450,000 in 1999. This increase is attributable  primarily to an increase in the
Company's  borrowings  under its line of credit  made  during the period to fund
working capital requirements.

       Other Income, net. Other income amounted to $55,000 in 2000 versus
$40,000 in 1999, resulting from recognized foreign currency transaction gains.

     Provision for Income Taxes. Despite incurring a loss before income taxes in
2000,  the Company has recorded a tax provision of $2.5 million.  This provision
is mainly  the  result of an  increase  in the  valuation  reserve  against  the
Company's  deferred  income tax assets.  The reserve was increased to reduce the
total deferred tax asset to an amount that management  believes will more likely
than not be realized. The difference between the statutory U.S. tax rate and the
Company's effective rate for 2000 is primarily due to the change in the deferred
tax asset  valuation  reserve  and foreign  taxes.  The  difference  between the
statutory U.S. tax rate and the Company's  effective rate for 1999 was primarily
the effect of foreign  operations  taxed at different  rates,  state taxes,  and
adjustments to the prior year tax provision based on the final 1998 tax returns.

Comparison of 1999 to 1998.

       Contract Revenue. Total contract revenue was $66.7 million and $73.8
million for the years ended December 31, 1999 and 1998, respectively. During
1998, the Company disposed of substantially all of the assets of its Erudite
subsidiary and Oil & Gas business unit. Included in 1998 revenue was $5.3
million from Erudite and $1.1 million from the Oil & Gas business unit. After
excluding these contract revenues from 1998 results, total revenues decreased
$0.7 million from 1998, or 1.0%.

       The Power business unit increased revenue by $1.2 million, or 3.9%, to
$32.1 million in 1999 from $30.9 million in 1998, primarily due to higher
domestic simulator upgrade projects and service contracts. The Process business
unit's revenues decreased by $1.9 million, or 5.2%, to $34.6 million in 1999
from $36.5 million in 1998. During the second half of 1999, the Process Business
Unit experienced an order slowdown as customers postponed additional investments
in their process control systems, pending the resolution of Y2K date issue
concerns.

       Gross Profit. Despite the lower revenues in 1999, gross profit increased
to $25.1 million in 1999 (37.6% of revenue) from $24.0 million in 1998 (32.6% of
revenue). The increase in gross profit as a percentage of revenues reflects a
higher component of upgrade projects in the Process business unit in 1999 than
in 1998, mainly due to customer concerns about Y2K date calculations in their
existing process control software. Such upgrades typically have fewer hardware
and instrumentation components and more license fees and application engineering
work, which tend to generate higher margins. In addition, the 1998 margins were
impacted slightly by low margins on revenues generated by Erudite and the Oil &
Gas business unit prior to the divestiture of their assets. Excluding the
margins on the revenues of these divested businesses, 1998 gross profit as a
percentage of revenue would have been 33.1%.

       Selling, General and Administrative Expenses. Selling, general and
administrative expenses totaled $22.6 million in 1999 (34.0% of revenues), an
11.3% increase from 1998 expenses of $20.3 million (27.6% of revenues). Other
than changes in research and development costs which increased $900,000 and are
discussed below, the increase reflects additional sales and marketing personnel
in the Process business unit, increased advertising and promotions related to
the Company's VirtualPlant suite of products and services, higher legal fees
related to the Company's new credit facility, and internal Y2K compliance
programs.

     Gross research and product development expenditures were $5.4 million (8.1%
of revenue) and $4.3 million (5.8% of revenue) for the years ended  December 31,
1999 and 1998,  respectively.  Of these  expenditures,  $2.5 million in 1999 and
$2.3 million in 1998 were capitalized.  Thus, net research and development costs
included in selling,  general and administrative  expenses were $2.9 million and
$2.0 million  during the years ended  December 31, 1999 and 1998,  respectively.
The Company continued to invest in the conversion of its D/3 Distributed Control
System (TM)  (Version  10.0 was released in October,  1999),  VPBatch(TM),  and
SimSuitePro(TM) products to the Microsoft Windows NT(R) platform.

       Depreciation and Amortization. Depreciation expense amounted to $1.3
million and $1.2 million during the years ended December 31, 1999 and 1998,
respectively.

       Amortization of goodwill was $388,000 and $365,000 during the years ended
December 31, 1999 and 1998, respectively.

       Operating Income (Loss). Operating income amounted to $744,000 (1.1% of
revenue) and $1.9 million (2.6% of revenue), for the years ended December 31,
1999 and 1998, respectively. The decrease in operating income was due mainly to
higher selling, general and administrative costs, as discussed above.

       Gain (Loss) on Sales of Assets. The gain on sales of assets in 1998
reflects the net pre-tax gain realized on the disposition of the Erudite and the
Oil & Gas business unit assets. During the second quarter of 1998, the Company
recorded a gain of $5.6 million on the sale of the Erudite assets. In the third
quarter of 1998, the Company recognized a ($5.0) million pre-tax loss on the
disposition of the Oil & Gas business unit assets. These sales and related gains
and losses are described more fully under Note 3, Acquisitions and dispositions,
in the "Notes to Consolidated Financial Statements".

     Interest Expense,  net. Interest expense increased to $450,000 in 1999 from
$350,000 in 1998. This increase is attributable  primarily to an increase in the
Company's  borrowings  under its lines of credit  made during the period to fund
working capital requirements.

       Other Income, net. Other income amounted to $40,000 in 1999 versus
$326,000 in 1998, resulting from recognized foreign currency transaction gains.

       Provision for Income Taxes. The Company's effective tax rate was 69.8% in
1999 versus 42.2% in 1998. The difference between the statutory U.S. tax rate
and the Company's effective rate for 1999 is primarily the effect of foreign
operations taxed at different rates, state taxes and adjustments to the prior
year tax provision based on the final 1998 tax returns.

Liquidity and Capital Resources.

       Operating Activities. The Company used $4.5 million in its operating
activities during 2000. The Company's $2.9 million revenue from licensing
software in exchange for stock of Avantium International B.V. was a non-monetary
transaction and had no impact on the Company's operating cash flow. Significant
changes in the Company's assets and liabilities included:

o    A $1.9 million reduction in contract receivables which is mainly related to
     the decline in overall revenues.

o    A $1.6 million  reduction in  inventories.  In 1999, the Process  stockroom
     inventory  increased  approximately  $650,000  due to  purchases  of  large
     supplies of various PC boards that are  extremely  expensive to purchase in
     small  quantities  and for which the  Company  had  forecasted  significant
     usage,  plus the return of some  material  from  customers.  In 2000,  this
     inventory decreased  approximately $800,000 as the Company made a concerted
     effort to reduce on-hand  inventory.  The balance of the decrease is due to
     the write-down of excess and slow moving inventory.

o    A $1.6 million  reduction  in billings in excess of revenues  earned due to
     the lower business volume in 2000.

       Net cash provided by operating activities was $2.6 million during 1999.
Significant changes in the Company's assets and liabilities included a $4.4
million reduction in contract receivables partially due to improvements in
internal collection processes; a $1.9 million reduction in accounts payable and
accrued expenses; and a $3.3 million reduction in billings in excess of
revenues earned.

        In 1998, the Company's operating activities used cash totaling $772,000.

       Investing Activities. Net cash used in investing activities totaled $3.3
million in 2000, including $472,000 of capital expenditures, $1.9 million of
capitalized software development costs, $658,000 in cash payments for acquired
businesses ($598,000 of contingent considerations for prior year acquisitions,
and $60,000 for notes payable related to a prior year acquisition), and $261,000
in connection with the disposition of the Company's Belgium subsidiary.

       In 1999, the Company used $4.1 million for investing activities,
consisting primarily of $1.4 million of capital expenditures, $2.5 million of
capitalized software development costs, and $930,000 in cash payments for
acquired businesses ($300,000 for the Mitech acquisition in 1999, $530,000 for
contingent considerations for prior year acquisitions, and $100,000 for notes
payable related to a prior year acquisition.) The Company received $731,000 from
Keane, Inc. as final payment on the 1998 Erudite sale.

     In  1998,  the  Company's  investing  activities  generated  $5.3  million,
consisting  primarily  of $9.7  million  from  the sale of  assets (see  Note 3,
Acquisitions  and  dispositions,   in  the  "Notes  to  Consolidated   Financial
Statements"), partially offset by $2.1 million used for capital expenditures and
$2.3 million for capitalized software development costs

     Financing  Activities.  In 2000, the Company obtained $6.6 million net cash
from the following financing activities:

o    The Company  increased its borrowings under its bank line of credit by $3.0
     million.
o    In January 2000, the Company issued 116,959 shares of its common stock to
     ManTech International Corporation for $500,000.
o    The assignment of two long-term  customer  sales-type  lease contracts to a
     finance company generated $1.1 million.
o    In the fourth quarter 2000, the Company issued a demand  promissory note to
     ManTech International Corporation, which allows the Company to borrow up to
     $1.8  million.  At December 31,  2000,  the Company had borrowed a total of
     $1.6  million.  This note is  subordinated  to the  Company's  bank  credit
     facility.  See additional discussion of this promissory note in the "Credit
     Facilities" section below.
o    Cash used to  collateralize  outstanding  letters of credit was  reduced by
     $202,000 due to the reduction in the value of outstanding letters of credit
     in 2000.

       In 1999, the Company generated $2.0 million net cash from financing
activities. The assignment of two long-term customer sales-type lease contracts
to a finance company generated $3.4 million cash, which was partially offset by
the paydown of the Company's credit lines ($.5 million), repayments under
capital lease obligations ($143,000) and the deposit of $735,000 into a bank
account for which the balance was used to collateralize two of the Company's
outstanding letters of credit.

       In 1998, the Company's financing activities used cash of approximately
$2.6 million, consisting primarily of $2.3 million in repayments under the
Company's lines of credit.

       Credit Facilities.

       On March 23, 2000, the Company entered into a new loan and security
agreement with a bank for a new credit facility with a maturity date of March
23, 2003. Borrowings from this facility were used to repay the existing debt
under the Company's previous credit facility. The line of credit (the "Credit
Facility") provides for borrowings up to a total of $10.0 million to support
working capital needs and foreign letters of credit. At December 31, 2000, the
Company's available borrowing base was $10.0 million, of which approximately
$9.3 million had been utilized. See Note 11, Long-term debt, in the "Notes to
Consolidated Financial Statements" for additional details about this line of
credit. When the Credit Facility was first entered into, ManTech International
Corp. provided a one-year $900,000 standby letter of credit to the bank as
additional collateral for the Company's Credit Facility and a limited guarantee
totaling $900,000. In July 2000, ManTech's guarantee was converted into a second
one-year $900,000 standby letter of credit to the bank, which was also used as
additional collateral for the Company's Credit Facility. GSE was allowed to
borrow up to 100% of the value of these two letters of credit.

     The loan and security agreement requires the Company to comply with certain
financial  ratios.  At December 31, 2000, the Company was not in compliance with
its  minimum  EBITDA  (earnings  before   interest,   taxes,   depreciation  and
amortization)  covenant,  its minimum working capital covenant, its tangible net
worth covenant,  or its total  liabilities to tangible net worth  covenant.  The
bank has provided a written waiver of the financial covenant  violations as well
as certain  covenant  modifications  to help  position  the  Company  for future
compliance.  Effective with the execution of the waiver,  the bank increased the
interest rate on outstanding  borrowings under the credit facility to the bank's
prime rate plus .75% (8.75% at March 31, 2001).

     In the fourth quarter of 2000, the Company issued a demand  promissory note
to ManTech  International  Corporation  that allowed the Company to borrow up to
$1.8 million at an interest  rate of prime plus one percent.  As of December 31,
2000, the Company had borrowed $1.6 million, which was used for working capital.
The promissory  note was secured by the Company's  pledge of its equity interest
in Avantium  International  B.V., but such security  interest was subordinate to
the first lien thereon by the Company's  bank. In the first quarter of 2001, the
promissory  note was amended to increase  the maximum  principal  amount to $2.1
million. Subsequently in the first quarter of 2001, and with ManTech's approval,
the Company issued a replacement  promissory  note in the amount of $2.1 million
to  ManTech  pursuant  to which the  Company's  obligations  to  ManTech  became
unsecured, and the  principal is  payable  ver  a  two  year  period,  in  equal
installments,  commencing  April 1,  2004 with  interest  payments  to  commence
monthly on July 1,  2001. The note permits ManTech to convert the principal into
GSE convertible  preferred stock at a conversion rate of $100 per share, pending
shareholder  approval.  ManTech  has  agreed  to  subordinate  the  note  to the
Company's Credit Facility.

       Other. As of December 31, 2000, the Company was contingently liable for
five letters of credit totaling $533,000. All of these letters of credit
represent payment bonds on contracts and have been cash collateralized.

Foreign Exchange.

       A portion of the Company's international sales revenue has been and may
be received in a currency other than the currency in which the expenses relating
to such revenue are paid. When necessary, the Company manages its foreign
currency exposure primarily by entering into foreign currency exchange
agreements and purchasing foreign currency options.

New Accounting Standards.

        Effective January 1, 2001, the Company will adopt Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" and No. 138 "Accounting for Certain Derivative Investments and
Certain Hedging Activities." These statements require that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The adoption of these
standards, including the valuation of derivative instruments outstanding on the
effective date, will not have a material impact on the Company's consolidated
financial statements.

Other Matters.

       To date, management believes inflation has not had a material impact on
the Company's operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

       The Company's market risk is principally confined to changes in foreign
currency exchange rates and potentially adverse effects of differing tax
structures. The Company's exposure to foreign exchange rate fluctuations arises
in part from inter-company accounts in which costs incurred in one entity are
charged to other entities in different foreign jurisdictions. The Company is
also exposed to foreign exchange rate fluctuations as the financial results of
all foreign subsidiaries are translated into U.S. dollars in consolidation. As
exchange rates vary, those results when translated may vary from expectations
and adversely impact overall expected profitability.

       The Company is also subject to market risk related to the interest rates
on its existing line of credit. As of March 31, 2001, such interest rates are
based on the prime rate plus three-quarters point.

       As of December 31, 2000, $10.8 million of the Company's debt was subject
to variable interest rates. A 100 basis-point change in such rates during the
year ended December 31, 2000 would have increased the Company's interest expense
by approximately $78,000.

                       GSE SYSTEMS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 2000, 1999, and 1998

1.  Business and liquidity

       GSE Systems, Inc. ("GSE Systems", "GSE" or the "Company") develops and
delivers business and technology solutions by applying process control,
simulation software, systems and services to the energy, process and
manufacturing industries worldwide. The Company's solutions and services assist
customers in improving quality, safety and throughput; reducing operating
expenses; and enhancing overall productivity.

       The Company's operations are subject to certain risks and uncertainties
including, among others, rapid technological changes, success of the Company's
product development, marketing and distribution strategies, the need to manage
growth, the need to retain key personnel and protect intellectual property, and
the availability of additional financing on terms acceptable to the Company.

       During the year ended December 31, 2000, the Company incurred significant
operating losses which resulted in non-compliance with certain financial
covenants included in the Company's bank credit facility. The Company has
obtained a waiver of the financial covenant defaults as well as certain covenant
modifications to help position the Company for future compliance. Nevertheless,
future compliance will depend upon achieving significantly improved operating
results during 2001 and beyond.

       Management has undertaken a number of initiatives during 2000 and 2001 to
improve operating results and cash flows including:

     (i)  The  restructuring  of the Process  business unit to reduce  operating
          costs.  Actions taken in 2000 included (a) personnel  reductions;  (b)
          the outsourcing of Process' manufacturing and assembly operations; and
          (c) the sale of Process'  unprofitable  Belgian  subsidiary  to Newton
          Integrated  Services,  B.V. of the Netherlands.  Included in operating
          results  for the year ended  December  31,  2000 are  revenues of $1.5
          million and operating losses, before allocation of corporate expenses,
          of $308,000 attributable to GSE Process Solutions N.V.

     (ii) The  sale  of  the   Company's   VirtualPlant   business  to  Avantium
          International B.V.("Avantium"). The asset sale closed on March 6, 2001
          and  included  certain  fixed  assets  of  the  Company,  intellectual
          property,  and the employment of certain  personnel in both the US and
          UK by Avantium.  GSE received 8% of Avantium's  stock, thus increasing
          its  holdings  in Avantium to  approximately  18%.  For the year ended
          December 31, 2000, the Company's VirtualPlant business had revenues of
          $6.1 million and an operating loss before allocation of corporate
          expenses of $3.4 million.

     (iii) ManTech International Corporation  ("ManTech")has agreed to allow the
          Company's  bank to draw upon  ManTech's  $1.8 million letter of credit
          which  supports  the  Company's  credit  facility,  thus paying down a
          portion  of the  Company's  bank  debt,  in  exchange  for  additional
          subordinated   debt  in  the  Company.(See   Note  16,  Related  party
          transations, in the "Notes to Consolidated Financial Statements.)

     Management  believes the initiatives  undertaken will enable the Company to
maintain compliance with the revised bank financial covenants as well as provide
sufficient  cash flow to meet the  Company's  obligations  as they  become  due.
However,  if the  initiatives  are not  successful  or if there  are  unforeseen
decreases in demand for the Company's  products or increases in working  capital
needs the  Company may be unable to meet the revised  bank  financial  covenants
and/or to generate  sufficient  cash flows from  operations.  In such case,  the
Company  will be  required  to  obtain  additional  covenant  modifications  and
additional  sources of funding.  There can be no  assurance  that such  covenant
modifications or funding, if needed, will be available.


2.  Summary of significant accounting policies

Principles of consolidation

       The accompanying consolidated financial statements include the accounts
of the Company and its wholly-owned subsidiaries. All intercompany balances and
transactions have been eliminated.

Accounting estimates

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

Revenue recognition

     Revenue  under  fixed-price  contracts  generally is  accounted  for on the
percentage-of-completion  method,  based on contract  costs incurred to date and
estimated  costs to  complete.  Estimated  contract  earnings  are  reviewed and
revised  periodically as the work progresses,  and the cumulative  effect of any
change is recognized in the period in which the change is determined.  Estimated
losses are charged  against  earnings in the period such losses are  identified.
The effect of changes in  estimates of contract  earnings was to increase  gross
profit by  approximately  $353,000 during the year ended December 31, 1999. Such
changes  were not  material  during the years ended  December 31, 1998 and 2000.
Revenues  from certain  consulting  or training  contracts  are  recognized on a
time-and-material  basis.  For  time-and-material  type  contracts,  revenue  is
recognized based on hours incurred at a contracted labor rate plus expenses.

Cash and cash equivalents

       Cash and cash equivalents consist of cash on hand and highly liquid
investments with maturities of three months or less at the date of purchase.

Inventories

       Inventories are stated at the lower of cost, as determined by the average
cost method, or market. Obsolete or unsaleable inventory is reflected at its
estimated net realizable value. Inventory costs include raw materials and
purchased parts.

Property and equipment

       Property and equipment are recorded at cost and depreciated using the
straight-line method with estimated useful lives ranging from three to ten
years. Leasehold improvements are amortized over the life of the lease or the
estimated useful life, whichever is shorter, using the straight-line method.
Upon sale or retirement, the cost and related amortization are eliminated from
the respective accounts and any resulting gain or loss is included in
operations. Maintenance and repairs are charged to expense as incurred.

Software development costs

       Certain computer software development costs are capitalized in the
accompanying consolidated balance sheets. Capitalization of computer software
development costs begins upon the establishment of technological feasibility.
Capitalization ceases and amortization of capitalized costs begins when the
software product is commercially available for general release to customers.
Amortization of capitalized computer software development costs is included in
cost of revenue and is provided using the straight-line method over the
remaining estimated economic life of the product, not to exceed five years.

Research and development

       Development expenditures incurred to meet customer specifications under
contracts accounted for under the percentage of completion method are charged to
contract costs. Company sponsored research and development expenditures are
charged to operations as incurred and are included in selling, general and
administrative expenses. The amounts incurred for Company sponsored research and
development activities relating to the development of new products and services
or the improvement of existing products and services, exclusive of amounts
capitalized, were approximately $1,679,000, $2,915,000, and $2,051,000, for the
years ended December 31, 2000, 1999, and 1998, respectively.

Asset impairment

       The Company periodically evaluates the recoverability of its long-lived
assets by comparing the carrying value of the intangible with the assets'
expected future cash flows, undiscounted and without interest costs. Estimates
of expected future cash flows represent management's best estimate based on
reasonable and supportable assumptions and projections. Impairments are
recognized in operating results to the extent that the carrying value exceeds
fair value. No impairment losses were recognized in 2000, 1999, or 1998.

Goodwill

       Goodwill represents the excess of purchase price for acquired businesses
over the fair value of net tangible and intangible assets acquired. These
amounts are amortized on a straight-line basis over periods ranging from seven
to fifteen years. The Company assesses the recovery of goodwill by determining
whether amortization of goodwill over its remaining life can be recovered
through undiscounted cash flows of the acquired operations. Goodwill impairment,
if any, is measured by determining the amount by which the carrying value of
goodwill exceeds its fair value based upon discounting of future cash flows.

Foreign currency translation

       Balance sheet accounts for foreign operations are translated at the
exchange rate at the balance sheet date, and income statement accounts are
translated at the average exchange rate for the period. The resulting
translation adjustments are included in accumulated other comprehensive income
(loss) in stockholders' equity. Transaction gains and losses, resulting from
changes in exchange rates, are included in other income (expense) in the
Consolidated Statements of Operations in the period in which they occur. For the
years ended December 31, 2000, 1999, and 1998, foreign currency transaction
gains were approximately $55,000, $40,000, and $326,000, respectively.

Warranties

       As the Company recognizes revenue under the percentage-of-completion
method, it provides an accrual for estimated future warranty costs based on
historical and projected claims experience.

Income taxes

       Deferred income taxes are provided under the asset and liability method.
Under this method, deferred income taxes are determined based on the differences
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to reverse. Valuation allowances are established when necessary to reduce
deferred tax assets to the amounts expected to be realized. Provision is made
for the Company's current liability for federal, state and foreign income taxes
and the change in the Company's deferred income tax assets and liabilities. No
provision has been made for the undistributed earnings of the Company's foreign
subsidiaries as they are considered permanently invested. Amounts of
undistributed earnings are not material to the overall consolidated financial
statements.

Earnings (loss) per share

       Basic earnings per share is computed based on the weighted average number
of outstanding common shares for the period. Diluted earnings per share adjusts
such weighted average for the potential dilution that could occur if stock
options, warrants or other convertible securities were exercised or converted
into common stock. Diluted earnings per share is the same as basic earnings per
share for the year ended December 31, 2000 because the effects of such items
were anti-dilutive.

       The number of common shares and common share equivalents used in the
determination of basic and diluted earnings (loss) per share was as follows:


                         

                                                                Years ended December 31,
                                                            2000           1999          1998

Weighted average shares outstanding - Basic                5,181,972      5,065,688     5,065,688

Weighted average shares outstanding - Diluted              5,181,972      5,351,474     5,107,428


       The difference between the amounts in 1999 and 1998 represents dilutive
options and warrants to purchase shares of common stock computed under the
treasury stock method, using the average market price during the related
periods.

Concentration of credit risk

       The Company is subject to concentration of credit risk with respect to
contract receivables. Credit risk on contract receivables is mitigated by the
nature of the Company's worldwide customer base and its credit policies. The
Company's customers are not concentrated in any specific geographic region, but
are concentrated in the energy and manufacturing industries. For the years ended
December 31, 2000 and 1999, one customer accounted for approximately 22% and
13%, respectively, of the Company's revenues. At December 31, 2000, the
contracts receivable balance related to this significant customer was
approximately $2.4 million, or 16.5% of that asset category, of which $1 million
was unbilled at year-end. In 2000, another customer accounted for approximately
11% of the Company's revenues. No single customer accounted for a significant
(greater than 10%) amount of the Company's revenue during the year ended
December 31, 1998.

Fair values of financial instruments

       The carrying amounts of current assets, current liabilities, and
long-term debt reported in the Consolidated Balance Sheets approximate fair
value.

Off balance sheet risk and foreign exchange contracts

       When necessary, the Company enters into forward exchange contracts,
options and swaps as hedges against certain foreign currency commitments. The
Company also enters into letters of credit and performance guarantees in the
ordinary course of business as required by certain contracts and proposal
requirements. The Company does not hold any derivative financial instruments for
trading purposes. Gains and losses on foreign exchange contracts and swaps are
recognized as part of the cost of the underlying transactions being hedged in
the period in which the exchange rates changed. Foreign exchange contracts have
an element of risk that the counterparty may not be able to meet the terms of
the agreement. However, the Company minimizes such risk exposure by limiting
counterparties to nationally recognized financial institutions. Foreign exchange
options contracts permit but do not require the Company to exchange foreign
currencies at a future date with counterparties at a contracted exchange rate.
Costs associated with such contracts are amortized over the life of the contract
matching the underlying receipts.

Reclassifications

       Certain reclassifications have been made to prior year amounts to conform
with the current year presentation.

New Accounting Standards

       Effective January 1, 2001, the Company will adopt Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" and No. 138 "Accounting for Certain Derivative Investments and
Certain Hedging Activities." These statements require that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The adoption of these
standards, including the valuation of derivative instruments outstanding on the
effective date, will not have a material impact on the Company's consolidated
financial statements.


3.  Acquisitions and dispositions

Acquisitions

       In April 1999, the Company completed two acquisitions for the Process
business unit using the purchase method of accounting. The Company purchased
certain assets and employed the associates of BatchCAD Limited, a United
Kingdom-based supplier of batch process development and design consulting
services and simulation software tools. The purchase price was approximately
$548,000 payable in cash in three equal installments on January 1, 2000, 2001
and 2002 and was allocated as follows (in thousands):


                         
Purchased software (property and equipment)                      $ 481
Trade receivables                                                   45
Property and equipment                                              22
                                                           ------------
      Total purchase price                                       $ 548
                                                           ============


       The Company also acquired all proprietary technology and software assets
from, and assumed substantially all customer contracts of, Mitech Corporation, a
Massachusetts-based supplier of neural network and artificial intelligence
software. The purchase price was $350,000 and was allocated 100% to property and
equipment as purchased software.

       In December 1997, the Company acquired 100% of the outstanding common
stock of J.L. Ryan, Inc. ("Ryan") for an initial purchase price of $1,000,000
and contingent consideration based on the performance of the business from 1998
to 2002. A minimum of $250,000 of such earnings payments for each of 1998 and
1999 was guaranteed by the Company. The Company paid $600,000 in cash upon the
closing of the transaction and entered into a promissory note payable in four
annual installments of $100,000 each beginning on January 2, 1999. This
acquisition was accounted for under the purchase method. For the years ended
December 31, 2000, 1999, and 1998, the contingent consideration in excess of the
minimum guaranteed amount was approximately $549,000, $411,000, and $166,000,
respectively, which the Company has recorded as additions to goodwill.

Dispositions

     On November 30,  2000,  the Company  completed  the sale of its GSE Process
Solutions N.V.  subsidiary ("GSE Belgium") to Newton  Integrated  Services B.V.,
pursuant to a stock purchase agreement,  whereby Newton Integrated Services B.V.
acquired  all of the assets and assumed all of the  liabilities  of GSE Belgium.
The aggregate  purchase  price for GSE Belgium was $1. The Company  recognized a
loss  before  income  taxes on this  transaction  of  $990,000.  Included in the
Consolidated  Statement of Operations  for the year ended December 31, 2000, are
revenues of $1.5 million and operating  losses of $346,000  attributable  to GSE
Belgium prior to the sale to Newton Integrated Services B.V.

       In November 1998, the Company completed the sale of certain assets
related to activities of its Oil & Gas business unit ("O&G"), to Valmet
Automation (USA), Inc. ("Valmet"), pursuant to an Asset Purchase Agreement,
effective as of October 30, 1998, by and between the Company and Valmet. The
Company recognized a loss before income taxes on this transaction of $5.0
million, including the write-off of approximately $2.9 million in capitalized
software development costs, since all operations that would support the
recoverability of these capitalized costs were sold. The Company received
approximately $742,000 in cash, subject to certain adjustments, and Valmet
assumed certain identified liabilities. Included in the Consolidated Statement
of Operations for the year ended December 31, 1998, are revenues of $1.1 million
and operating losses of $721,000 attributable to O&G prior to the sale to
Valmet. See Note 18, Segment information, for historical revenues and business
unit contributionprovided by O&G during 1998.

       In May 1998, the Company completed the sale of substantially all of the
assets of GSE Erudite Software, Inc. ("Erudite") to Keane, Inc. ("Keane"),
pursuant to an Asset Purchase Agreement, dated as of April 30, 1998, by and
among the Company, Erudite and Keane. The aggregate purchase price for the
Erudite assets was approximately $9.6 million (consisting of $8.9 million in
cash and $731,000 in the form of an uncollateralized promissory note due on
April 30, 1999). In connection with the transaction, Keane purchased certain
assets with a book value of $4.4 million and assumed certain operating
liabilities totaling approximately $2.2 million. The Company recognized a gain
before income taxes on this transaction of $5.6 million. In connection with the
sale of these assets, the Company wrote off approximately $800,000 in
capitalized software development costs, as well as $321,000 of purchased
software, since all operations that would support the recoverability of these
costs were sold. The write-off of these costs is reflected in the calculation of
the gain on the sale. Included in the Consolidated Statement of Operations for
the year ended December 31, 1998, are revenues of $5.3 million and operating
losses of $64,000 attributable to Erudite prior to the sale to Keane. See Note
18, Segment information, for historical revenues and business unit contribution
provided by Erudite during 1998.


4.  Investment in Avantium International B.V.

       On February 24, 2000, the Company licensed certain of its simulation
software products to Avantium Technologies B.V. ("Avantium") in exchange for
251,501 shares of Avantium preferred stock, valued at $2.5 million, and 352,102
shares of Avantium common stock, valued at $349,000. The software license, which
is perpetual in nature, gives Avantium the right to use the software in the
development of new software products. Each share of preferred stock is
convertible into common stock. Subject to certain restrictions, in the event
that Avantium has not conducted an initial public offering (or been purchased)
within five years, the Company and certain other holders of preferred shares
may, at their option, have their shares redeemed by Avantium, for the greater of
(i) the original purchase price plus 8% interest compounded annually plus any
accrued and unpaid dividends whether or not declared, or (ii) the fair market
value of the shares on an as-if-converted-into-common-shares-basis plus any
accrued and unpaid dividends.

       Avantium was formed to develop high-speed experimentation and simulation
("HSE&S") technologies for application in new product and process development in
pharmaceutical, petrochemical, fine chemical, biotechnology and polymers
industries. Avantium expects to develop HSE&S technologies through in-house
development and contract research at leading universities, hardware developers
and informatics companies. Avantium has various investors, including Shell
International Chemical, SmithKline Beecham, W.R. Grace, three major European
universities and two venture capital firms.

       During the year ended December 31, 2000, the Company recognized
software-licensing revenue of $2.9 million based on the fair value of the
consideration received from Avantium. The fair value was established based on
cash paid by other investors for their respective preferred and common stock
interests in Avantium. The Company has delivered all elements of the software
and has no other obligations to Avantium, other than standard warranty. The
Company will account for its investment in Avantium using the cost method of
accounting based on management's conclusion that the Company does not have
significant influence with respect to the operations of Avantium. During the
year ended December 31, 2000, the Company also received an additional $2.9
million contract from Avantium to make certain improvements and enhancements to
the software on a best efforts basis. The rates and margins in the contract are
comparable to those the Company earns performing services for its existing
customers.

     As a result of the experience with Avantium in 2000, the Company  concluded
that a  combination  of  the  relevant  interests  of the  two  companies  would
significantly  increase  the  potential  of  both  organizations.  In  addition,
focusing  the  technical  and  marketing  resources  of  Avantium  and  the  GSE
VirtualPlant  team would  produce  significant  cost  savings.  Accordingly,  in
November 2000,  the Company  signed a letter of intent to sell its  VirtualPlant
business to Avantium.  See Note 21,  Subsequent  events,  for the details of the
sale which was sale which was finalized in 2001.

Facility") under which the Company and its subsidiaries, GSE Process Solutions,
Inc. and GSE Power Systems, Inc., are jointly and severally liable as
co-borrowers. The Credit Facility provides for borrowings to support working
capital needs and foreign letters of credit ($2.0 million sublimit). The line is
collateralized by substantially all of the Company's assets and provides for
borrowings up to 85% of eligible accounts receivable, 50% of eligible unbilled
receivables and 40% of eligible inventory (up to a maximum of $1.2 million). In
addition, ManTech International Corp. provided $1.8 million in standby letters
of credit to the bank as additional collateral for the Company's Credit
Facility. The Company is allowed to borrow up to 100% of the letter of credit
value. GP Strategies Corporation has provided a limited guarantee totaling $1.8
million. The interest rate on this line of credit is based on the bank's prime
rate (9.5% as of December 31, 2000), with interest only payments due monthly. At
December 31, 2000, the Company's available borrowing base was approximately $10
million, of which approximately $9.3 million had been utilized.

     The loan and security agreement requires the Company to comply with certain
financial  ratios and  precludes  the Company from paying  dividends  and making
acquisitions  beyond certain limits without the bank's consent.  At December 31,
2000, the Company was not in compliance with its minimum EBITDA (earnings before
interest,  taxes,  depreciation and amortization)  covenant, its minimum working
capital  covenant,  its tangible net worth covenant or its total  liabilities to
tangible  net worth  covenant.  The bank has  provided  a written  waiver of the
financial covenant violations as well as certain covenant  modifications to help
position the Company for future compliance.  Effective with the execution of the
waiver, the bank increased the interest rate on outstanding borrowings under the
credit facility to the bank's prime rate plus .75%.

Obligations under financing leases

        In December 1998, March 1999, October 2000 and November 2000, the
Company entered into four separate contracts with a customer for the lease of
certain hardware and software under 36-month leases. The Company has accounted
for the leases as sales-type leases. The Company assigned the payments due under
the sales-type leases to a third-party financing company and received proceeds
of $1,141,000 in 2000 and $3,432,000 in 1999. Since the Company remains
contingently liable for amounts due to the third-party financing company, the
remaining investment in and obligation under the financing leases are reflected
in the Company's balance sheets as follows:

        Minimum rentals receivable under these leases at December 31, 2000
amount to $1,783,000 in 2001, $456,000 in 2002, and $342,000 in 2003. As of
December 31, 2000, the components of the net investment in the sales-type leases
are total minimum rentals receivable of $2,581,000, less unearned interest
income of $320,000.

        The provision for income taxes varies from the amount of income tax
determined by applying the applicable U.S. statutory rate to pre-tax (loss)
income as a result of the following:

        Deferred income taxes arise from temporary differences between the tax
bases of assets and liabilities and their reported amounts in the financial
statements. A summary of the tax effect of the significant components of the
deferred income tax assets (liabilities) is as follows:

        At December 31, 2000, the Company had available $15,497,000 and
$2,068,000 of domestic and foreign net operating loss carryforwards,
respectively, which expire between 2007 and 2020. In addition, the Company had
$339,000 of foreign tax credit carryforwards, which expire between 2000 and
2004. These carryforwards will be utilized to reduce taxable income in
subsequent years. A portion of the net operating losses were generated by
certain of the Company's predecessors prior to the formation of the Company and,
as a result, there are limitations on the amounts that can be utilized to offset
taxable income in a given year.

        In assessing the realizability of deferred tax assets, management
considers whether it is more likely than not that some or all of the deferred
tax assets will not be realized. The ultimate realization of deferred tax assets
is dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. Management considers the
scheduled reversal of deferred tax liabilities and projected future income in
making this assessment. Based upon the level of historical taxable income
generated by the Company's Process and Power business units and projections for
taxable income in fiscal 2001, management believes it is more likely than not
that the Company will realize the benefits of these deductible differences, net
of the valuation allowance at December 21, 2000.


13.  Capital stock

        As of December 31, 2000, the Company had 10,000,000 total shares of
capital stock authorized, of which 8,000,000 are designated as common stock and
2,000,000 are designated as preferred stock. As of December 31, 2000 and 1999,
there are no shares of preferred stock outstanding. The Board of Directors has
the authority to establish one or more classes of preferred stock and to
determine, within any class of preferred stock, the preferences, rights and
other terms of such class.

        In 1998, in connection with the Company's then existing credit facility,
the Company had arranged for certain guarantees to be provided on its behalf by
GP Strategies and ManTech. In consideration for these guarantees, the Company
granted each of ManTech and GP Strategies warrants to purchase shares of the
Company's common stock; each of such warrants provides the right to purchase
150,000 shares of the Company's common stock at $2.375 per share. In 1998, the
Company recorded $300,000 as the estimated fair value of such warrants in the
consolidated financial statements and amortized such value over the life of the
initial guarantee, which expired in June 1999. During 1999 and 1998, the Company
recognized expense related to these warrants totaling $120,000 and $180,000,
respectively.


14.  Stock options

Long term incentive plan

        During 1995, the Company established the 1995 Long-Term Incentive Stock
Option Plan (the "Plan"), which includes all officers, key employees and
non-employee members of the Company's Board of Directors. All options to
purchase shares of the Company's common stock under the Plan expire seven years
from the date of grant and generally become exercisable in three installments
with 40% vesting on the first anniversary of the grant date and 30% vesting on
each of the second and third anniversaries of the grant date, subject to
acceleration under certain circumstances. The Company had reserved 1,875,000
shares of common stock for issuance of stock options under the terms of the
Plan. At December 31, 2000, the Company had 427,015 shares of common stock
reserved for the future grants under the Plan.

       Stock option activity under the Plan is as follows:

     The  Company  accounts  for  grants  under  the  Plan  in  accordance  with
Accounting  Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to
Employees," and related  interpretations.  Accordingly,  no compensation expense
has been  recognized as all options  granted under the Plan have been granted at
an exercise price equal to the fair value of the underlying  common stock on the
date of grant. Had compensation  expense been determined based on the fair value
at the grant  dates for  awards  under the Plan  consistent  with the fair value
method of FAS No. 123,  "Accounting for Stock Based Compensation," the Company's
pro forma net income (loss),  and basic and diluted  earnings  (loss) per common
share would have been approximately  ($11.1 million) and ($2.14),  respectively,
in 2000;  ($615,000) and ($.12),  respectively,  in 1999; and $900,000 and $.18,
respectively, in 1998.

       The fair value of each option is estimated on the date of grant using a
Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants during the years ended December 31, 2000, 1999, and
1998: expected volatility of 110%, 82%, and 61%; dividend yield of 0%; risk-free
interest rates ranging from 5.2% to 6.6%; and expected terms ranging from 3 to 7
years. The weighted-average fair value of options granted during 2000, 1999, and
1998 was $3.93 per share, $2.82 per share, and $2.79 per share, respectively.

       Total rent expense under operating leases for the years ended December
31, 2000, 1999, and 1998 was approximately $2,101,000, $2,013,000, and
$2,134,000, respectively.

Letters of credit and performance bonds

       As of December 31, 2000, the Company was contingently liable for
approximately $533,000 under five letters of credit used as payment bonds on
contracts, all of which were secured by cash deposits classified as restricted
cash in the consolidated balance sheet.

       During 1998, the Company placed approximately $332,000 in escrow as a
performance bond deposit in connection with a simulator contract in Taiwan. Of
this amount, approximately $221,000 was held in escrow until April 2000, and
approximately $111,000 will be held in escrow until April 30, 2003. These
deposits are classified as other assets in the Consolidated Balance Sheets at
December 31, 2000 and 1999.

Contingencies

       Various actions and proceedings are presently pending to which the
Company is a party. In the opinion of management, the aggregate liabilities, if
any, arising from such actions are not expected to have a material adverse
effect on the financial position, results of operations or cash flows of the
Company.


16.  Related party transactions

     In the fourth quarter of 2000, the Company issued a demand  promissory note
to ManTech  International  Corporation  that allowed the Company to borrow up to
$1.8 million at an interest  rate of prime plus one percent.  As of December 31,
2000, the Company had borrowed $1.6 million, which was used for working capital.
The promissory  note was secured by the Company's  pledge of its equity interest
in Avantium  International  B.V., but such security  interest was subordinate to
the first lien thereon by the Company's  bank. In the first quarter of 2001, the
promissory  note was amended to increase  the maximum  principal  amount to $2.1
million. Subsequently in the first quarter of 2001, and with ManTech's approval,
the Company issued a replacement  promissory  note in the amount of $2.1 million
to  ManTech  pursuant  to which the  Company's  obligations  to  ManTech  became
unsecured,  and the  principal  is  payable  over a two  year  period,  in equal
installments,  commencing  April 1,  2004 with  interest  payments  to  commence
monthly on July 1, 2001. The note permits  ManTech to convert the principal into
GSE convertible  preferred stock at a conversion rate of $100 per share, pending
shareholder  approval.  ManTech  has  agreed  to  subordinate  the  note  to the
Company's credit facility.

       In January 2000, the Company issued 116,959 shares of its common stock,
at fair value, to ManTech for $500,000. The proceeds of the stock issuance were
used for working capital.


17.  Employee benefits

       The Company has a qualified defined contribution plan that covers
substantially all U.S. employees under Section 401(k) of the Internal Revenue
Code. Under this plan, the Company's stipulated basic contribution matches a
portion of the participants' contributions based upon a defined schedule.
Contributions are invested by an independent investment company in one or more
of several investment alternatives. The choice of investment alternatives is at
the election of each participating employee. The Company's contributions to the
plan were approximately $340,000, $359,000, and $468,000 for the years ended
December 31, 2000, 1999, and 1998, respectively.


18.  Segment information

     The Company's two  reportable  segments are its core business units Process
and Power.  The Company's  VirtualPlant  business is reported  under the Process
segment. The accounting policies of the segments are the same as those described
in Note 2, Summary of significant  accounting policies. The Company is primarily
organized on the basis of these two business units. The Company has a wide range
of knowledge of control and simulation  systems and the processes  those systems
are  intended  to  improve,  control  and  model.  The  Company's  knowledge  is
concentrated  heavily in the process  industries,  which include the  chemicals,
food & beverage, and pharmaceuticals  fields, as well as in the power generation
industry.  The Process business unit is primarily engaged in process control and
simulation in a variety of commercial industries. Contracts typically range from
three to nine months. The Power business unit is primarily engaged in simulation
for the power generation industry,  with the vast majority of customers being in
the nuclear power  industry.  Contracts  typically range from 18 months to three
years.

       The Company evaluates the performance of its business units utilizing
"Business Unit Contribution", which is substantially equivalent to earnings
before interest and taxes before allocating any corporate expenses. The segment
information regarding the divested  businesses is also included below (see
Note 3, Acquisitions and dispositions, and Note 4, Investment in Avantium
International B.V.).

     The first quarter 200 includes  contract  revenues and related  profit from
the  licensing of software to Avantium,  as described in Note 4,  Investment  in
Avantium International B.V.

     The  fourth  quarter  2000  net loss  includes  the  following  significant
charges: a $710,000  provision to write-down Process inventory,  a $990,000 loss
on the sale of the Company's  Belgian  subsidiary (see Note 3,  Acquisitions and
dispositions), and a $4.3 million income tax charge to increase the deferred tax
asset valuation allowance (see Note 12, Income taxes).


21.  Subsequent events

Sale of VirtualPlant business

       On March 6, 2001, the Company sold its VirtualPlant business to Avantium
International B.V. ("Avantium") purchased certain fixed assets and intellectual
property (including BatchCAD and BatchWizard software products) of the Company,
and employed certain personnel in both the US and the UK. GSE received 8% of
Avantium's stock, thus increasing its holdings in Avantium to approximately 18%.
GSE retains one seat on the supervisory board of Avantium. Also, the Company
licensed their process control and simulation software ("GSE Process Software")
exclusively to Avantium for the R&D market. This licensing arrangement includes
free updates to the GSE Process Software. In return, GSE received a royalty-free
license to use any upgrades of the GSE Process Software produced by Avantium in
the manufacturing market. GSE also received a royalty-free license to use and
produce upgrades of the BatchWizard software in the manufacturing market.
Avantium and GSE will continue to work together in the marketplace and in
product development so that common clients will be able to use Avantium's
VirtualPlant technology to develop scalable products that will fit together at
the manufacturing level with GSE's process control and simulation products.
