                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
         For the Three and Nine Months ended September 30, 2002 and 2001
                                   (Unaudited)
1.       Basis of Presentation

            The consolidated financial statements included herein have been
        prepared by GSE Systems, Inc. (the "Company") without independent audit.
        In the opinion of the Company's management, all adjustments and
        reclassifications of a normal and recurring nature necessary to present
        fairly the financial position, results of operations and cash flows for
        the periods presented have been made. Certain information and footnote
        disclosures normally included in financial statements prepared in
        accordance with accounting principles generally accepted in the United
        States have been condensed or omitted. These consolidated financial
        statements should be read in conjunction with the consolidated financial
        statements and notes thereto included in the Company's Annual Report on
        Form 10-K for the year ended December 31, 2001 filed with the Securities
        and Exchange Commission on March 29, 2002.

2.       Basic and Diluted Earnings Per Common Share

            Basic earnings per share is based on the weighted average number of
        outstanding common shares for the period. Diluted earnings per share
        adjusts the weighted average shares outstanding for the potential
        dilution that could occur if stock options, warrants, or convertible
        preferred stock were exercised or converted into common stock. The
        number of common shares and common share equivalents used in the
        determination of basic and diluted earnings per share were as follows:

        warrants and convertible  preferred stock to purchase shares of common
        stock  computed  under the treasury  stock  method,  using the average
        market price during the period. The net  income(loss)for the three and
        nine month period ended  September 30, 2002 was decreased by preferred
        stock dividends of $59,000 and $175,000,  respectively, in calculating
        the per share amounts.  For the three and nine months ended  September
        30, 2001, there were no preferred stock  dividends.  Conversion of the
        preferred  stock was not assumed  for the three  months or nine months
        ended September 30, 2002 because the impact was anti-dilutive.

3.       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. Inventories consist of
        the following:

4.       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 determined using the straight-line method over the remaining
        estimated economic life of the product, not to exceed five years.

            Software development costs capitalized were $654,000 and $282,000
        for the three months ended September 30, 2002 and 2001, respectively of
        which $357,000 and $227,000 were incurred through third party
        contractors, respectively. Total amortization expense was $422,000 and
        $492,000 for the three months ended September 30, 2002 and 2001,
        respectively.

            For the nine months ended September 30, 2002 and 2001, software
        development costs capitalized were $2.2 million and $584,000,
        respectively of which $1.4 million and $350,000 were incurred through
        third party contractors, respectively. Total amortization expense was
        $1.3 million and $1.6 million for the nine months ended September 30,
        2002 and 2001, respectively.

          The  increase  in  the  Company's   capitalized  software  development
          expenditures was related to:

        * The  development  of  Version  11.0  of its D/3  Process  Automation
          System.  The major  enhancements to the system include  improved alarm
          handling and advanced  system  diagnostics.  In addition,  the Company
          will introduce two new more cost effective  process  controllers based
          on  the  use  of  modern  PCI  back  plane   technology  and  improved
          diagnostics.  The project was completed for  commercial  release as of
          October 1, 2002.

        * The  development of the Process D/3 Compact,  a smaller,  redesigned
          version  of the D/3  distributed  control  system  which  is  aimed at
          smaller  automation  applications.   This  entry-level  offering  will
          combine the low cost found in  Programmable  Logic  Controllers  (PLC)
          solutions with the high functionality of a distributed control system.
          The  project was  completed  for  commercial  release as of October 1,
          2002.

        * The replacement of the Graphic User  Interfaces  (GUI) for our Power
          GSuite and  Topmeret  tools with a Java based GUI,  which will provide
          platform  independence and internet enabling.  The project is expected
          to be completed and ready for commercial release by January 1, 2003.

5.       Investment in Avantium International B.V.

             As of September 30, 2002, the Company owns approximately 6% of
        Avantium International B.V. ("Avantium") which it acquired in two
        transactions described below. The Company accounts 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.

             On February 24, 2000, the Company licensed certain of its
        simulation software products to Avantium in exchange for 251,501 shares
        of Avantium preferred stock and 352,102 shares of Avantium common stock,
        valued at $2.8 million. 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.

             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, Akzo Nobel, three major European
        universities and various venture capital firms.

             On March 6, 2001, the Company sold its VirtualPlant business to
        Avantium. Avantium purchased certain fixed assets and intellectual
        property (including BatchCAD and BatchWizard software products),
        obtained perpetual licenses to certain GSE Process software products,
        and employed certain personnel in both the U.S. and the UK. GSE received
        200,000 shares of Avantium preferred stock and 280,000 shares of
        Avantium common stock, which increased its equity interest in Avantium
        to approximately 19% and the carrying value of its investment to $7.5
        million. The Company recognized a gain on the sale of its VirtualPlant
        business of approximately $3.3 million, before income taxes. This gain
        was determined based on the estimated fair value of the Avantium stock
        received, based on an independent appraisal, net of the book value of
        the assets sold and the estimated costs to settle severance with
        employees terminated from GSE and other transaction expenses.

             On February 7, 2002, Avantium completed a private placement round
        of financing which resulted in 20 million Euros in new capital and the
        conversion of 11 million Euros of convertible debt. The equity issuance
        and debt conversion diluted GSE's ownership in Avantium to 6.1%. The
        estimated fair market value of Avantium following the financing was
        $47.4 million. Accordingly, the Company concluded that this transaction
        was evidence of "an other than temporary decline" in the fair value of
        its investment in Avantium. Thus, in the fourth quarter 2001, the
        Company wrote down its investment in Avantium to $2.9 million and
        recognized a $4.6 million pre-tax charge.

             The Company continues to monitor the fair value of its investment
        in Avantium. There can be no assurance that further write-downs will not
        occur.

6.       Long-term Debt

            The Company's long-term debt consists of the following notes payable
         and other financing arrangements:

             Line of Credit

             The Company has a $10.0 million bank line of credit 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). GP Strategies Corporation, one of the
        Company's major stockholders, 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 plus 0.75% (5.50% as of September 30, 2002), with
        interest only payments due monthly. At September 30, 2002, the Company's
        available borrowing base was approximately $4.9 million of which
        approximately $3.7 million had been utilized. The credit facility
        expires on March 23, 2003. Accordingly, the Company has classified the
        borrowings under the line of credit as current as of September 30, 2002.

             The credit facility requires the Company to comply with certain
        financial ratios on a monthly basis and precludes the Company from
        paying dividends and making acquisitions beyond certain limits without
        the bank's consent. As of July 31, 2002 and August 31, 2002, the Company
        was not in compliance with one of its financial ratio covenants. The
        Company has received a written waiver from the bank for its July and
        August noncompliance. At September 30, 2002, the Company was in
        compliance with all of the covenants.

             Obligations under financing leases

             As of September 30, 2002, the Company has seven 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
        approximately $2.6 million for the nine months ended September 30, 2002
        and $2.2 million for the year ended December 31, 2001.






        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:

         Notes Payable to Related Parties

             On June 25, 2001, the Company issued an unsecured promissory note
        to ManTech for $1.0 million at an interest rate of prime plus one
        percent. The Company used the loan proceeds for working capital
        purposes. The note is subordinated to the Company's credit facility. As
        of September 30, 2002, the Company has $650,000 due to ManTech. The
        Company has an additional unsecured promissory note to a former employee
        for $79,000 which expires April 14, 2005.

7.       Series A Preferred Stock

            On December 5, 2001, ManTech elected to convert $3.9 million of
        subordinated debt into Series A convertible preferred stock at a
        conversion rate of $100 per share. The Series A convertible preferred
        stock has no voting rights and bears dividends at the rate of 6% per
        annum payable quarterly. Dividends will accumulate if not paid quarterly
        and compounded interest will accrue on any unpaid dividends. ManTech, at
        its discretion, has the right to convert each share of Series A
        convertible preferred stock into GSE common stock at a purchase price of
        $2.645 per share at any time after a one-year holding period from the
        date of issuance. In December 2004, the Series A convertible preferred
        stock automatically converts into GSE common stock. As of September 30,
        2002, the Company had paid all dividends due except for $117,000 for the
        second and third quarter 2002.

8.       Letters of Credit

            As of September 30, 2002, the Company was contingently liable for
        approximately $672,000 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.

9.       Income Taxes

            The Company's effective tax rate is based on the best current
        estimate of its expected annual effective tax rate. The difference
        between the statutory U.S. tax rate and the Company's effective tax rate
        for the quarters ended September 30, 2002 and 2001 is primarily due to
        the effects of foreign operations being taxed at different rates and
        state income taxes. As of September 30, 2002 and December 31, 2001, the
        aggregate deferred tax assets are recorded net of a valuation allowance

10.      Segment Information

            The Company's two reportable segments are its core business units
        Process and Power. (The Company's VirtualPlant business, which was sold
        in March 2001, is reported under the Process segment.) 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
        corporate expenses.

            The table below presents information about the reportable segments:

            Contract revenue for the Process segment includes revenue for the
        VirtualPlant business of $507,000 for the nine months ended September
        30, 2001. The Company sold its VirtualPlant technology and assets in
        March 2001 (see Note 5, Investment in Avantium International B.V.).
        Business unit contribution for the Process segment includes a loss for
        VirtualPlant of $471,000 prior to its sale.

11.      Goodwill

            On January 1, 2002, the Company adopted Statement of Financial
       Accounting Standards No. 142 "Goodwill and Other Intangible Assets"
       ("SFAS No. 142"). SFAS No. 142 requires that goodwill and intangible
       assets with indefinite useful lives no longer be amortized, but instead
       be tested for impairment at least annually. During the second quarter of
       2002, the Company completed its transitional impairment test and
       determined the fair value of each of its reporting units' net assets
       exceeded their carrying value, and therefore there was no impairment of
       goodwill.

            Net income and net income per share for the three and nine months
       ended September 30, 2001, adjusted to eliminate historical amortization
       of goodwill and related tax effects, are as follows:

Item 2.  Management's  Discussion  and  Analysis  of Results of  Operations  and
Financial Condition

Cautionary Statement Regarding Forward-Looking Statements

         This report contains certain forward-looking statements. Any statements
contained herein that are not statements of historical facts may be deemed
forward-looking statements. These statements are based on management's current
beliefs and expectations and are subject to numerous risks and uncertainties and
changes in circumstances. Actual results may differ materially from these
forward-looking statements due to changes in global, economic, business,
governmental, technical, competitive, market and regulatory factors.

Critical Accounting Policies and Estimates

         In preparing the Company's consolidated financial statements,
management makes several estimates and assumptions that affect the Company's
reported amounts of assets, liabilities, revenues and expenses. Those accounting
estimates that have the most significant impact on the Company's operating
results and place the most significant demands on management's judgment are
discussed below. For all of these policies, management cautions that future
events rarely develop exactly as forecast, and the best estimates may require
adjustment.

         Revenue Recognition on Long-Term Contracts. The Company uses the
percentage-of-completion revenue recognition methodology to record revenue under
its long-term fixed-price contracts in accordance with the AICPA Statement of
Position 81-1, "Accounting for Performance of Construction-Type and Certain
Production-Type Contracts". This methodology recognizes income as work
progresses on the contract and is based on an estimate of the income earned to
date, less income recognized in earlier periods. The Company bases its estimate
of the degree of completion of the contract by reviewing the relationship of
costs incurred to date to the expected total costs that will be incurred on the
project. The Company's project managers are responsible for estimating the costs
to be incurred at the beginning of each project and are responsible for updating
the estimate as the project progresses. Management reviews the status of each
project periodically with the project managers and determines whether the cost
estimates are reasonable. If changes in the estimated costs to complete the
projects are required, the cumulative impact on the percentage of completion
revenue calculation is recognized in the period identified. Whenever evidence
indicates that the estimated total cost of a contract will exceed its total
contract value, the Company's operating results are charged for the full amount
of the estimated losses immediately. Uncertainties inherent in the performance
of contracts include labor availability and productivity, material costs, change
order scope and pricing, software modification issues and customer acceptance
issues. The reliability of these cost estimates is critical to the Company's
revenue recognition as a significant change in the estimates can cause the
Company's revenue and related margins to change significantly from the amounts
estimated in the early stages of the project.

         Capitalization of Computer Software Development Costs. In accordance
with Statement of Financial Accounting Standards (SFAS) No. 86 "Accounting for
the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed," the
Company capitalizes computer software development costs incurred after
technological feasibility has been established, but prior to the release of the
software product for sale to customers. Once the product is available to be
sold, the Company begins to amortize the costs over the estimated useful life of
the product, which normally ranges from three to five years. At September 30,
2002, the Company has net capitalized software development costs of $4.7
million. On an annual basis, the Company assesses the recovery of the
unamortized software computer costs by estimating the net undiscounted cash
flows expected to be generated by the sale of the product. If the undiscounted
cash flows are not sufficient to recover the unamortized software costs the
Company will write-down the investment to its estimated fair value based on
future discounted cash flows. The excess of any unamortized computer software
costs over the related net realizable value is written down and charged to
income. Significant changes in the sales projections could result in an
impairment with respect to the capitalized software that is reported on the
Company's consolidated balance sheet.

         Deferred Income Tax Valuation Allowance. Deferred income taxes arise
from temporary differences between the tax bases of assets and liabilities and
their reported amounts in the financial statements. As required by SFAS No. 109
"Accounting for Income Taxes", management makes an annual assessment of the
realizability of the Company's deferred tax assets. In making this assessment,
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 taxable income of the Company in making this assessment. A valuation
allowance is recorded to reduce the total deferred income tax assets to its net
realizable value. At September 30, 2002, the Company's deferred tax assets
related primarily to a U.S. net operating loss carryforward of $13.5 million
which can be utilized over the next twenty years. Management believes it is more
likely than not that the Company will generate sufficient taxable income to
recover $1.6 million of its deferred tax asset. The recovery of the remaining
net deferred tax asset is significantly less certain and, accordingly, the
Company has established a valuation allowance for the balance of its deferred
tax assets of $4.9 million. If future taxable income is less than management's
estimates, the amount of the net deferred tax assets on the Company's
consolidated balance sheet will require an additional valuation allowance.
Additionally, if the Company is able to realize higher taxable income the
valuation allowance could be reduced.

General Business Environment

         GSE Systems, Inc. ("GSE Systems", "GSE" or the "Company") is a world
leader in real-time power plant simulation and process automation and control.
The Company provides simulation solutions and services to the nuclear and fossil
electric utility industry, as well as process industries such as the chemical
and petrochemical industries. The Company's process automation products optimize
batch and hybrid plant control for the specialty chemical, food and beverage,
and pharmaceutical industries. The Company operates through two business
segments, Power Simulation and Process Automation.

         Power Simulation Business.

         The Company's Power Simulation Business Unit ("Power") is continuing
its focus on both the nuclear power and fossil fuel simulation markets. As the
leading provider of simulation systems for the nuclear industry, the Company
sees continued opportunities as the nuclear power industry goes through plant
life extensions. The fossil market segment has been hit by the downturn in the
world's energy market. While new plant construction has slowed, the Company sees
an opportunity to provide plant optimization solutions to customers trying to
maximize plant output in a very competitive market. 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 operation efficiency improvements for both nuclear and
fossil utilities.

         The Company recently announced an agreement with RedStorm Scientific
LLC for the use of GSE software in the drug discovery process. RedStorm
Scientific LLC is a privately held computational drug design company. RedStorm
Scientific LLC converted to a Delaware corporation, Red Storm Scientific Inc.,
in April 2002. Its technology (patents pending), known as Fyrestar, utilizes
bio-informatics and computer-aided molecular design to create lead compounds
that are developed into successful new drugs. It greatly reduces the significant
cost associated with screening thousands of potential compounds common in the
drug development process. Under the terms of the agreement, GSE will utilize its
eSMART simulation software and graphical user interface to enable scientists to
easily access and use the Fyrestar technology, graphically displaying results as
the calculations take place. This will enable scientists to adjust their
assumptions in real time, and further improve results.

         In light of recent security concerns at nuclear plants and other
sensitive locations, the Company has begun marketing the technology it acquired
several years ago for plant access control and intrusion detection. The Company
has implemented its system at several nuclear power plants in the U.S. and is
pursuing applications at other facilities. The Company has signed a contract
with a major nuclear utility to provide our security system for one of its
nuclear power plants, and licenses to extend the technology to each of the
nuclear plants operated by the utility. Proposal activity in the nuclear plant
access control and intrusion detection system market has increased sharply in
the third quarter. The system is a command and control center that integrates
information card readers, biometrics, closed circuit TV and other field devices
used for intrusion detection and personnel access control. The Company has
recently hired a manager to develop a business plan for the expansion of this
security business.

         The Company is also teaming with ManTech Security Technologies
Corporation, a subsidiary of one of its major shareholders, MECX and Protection
Strategies, Inc. to provide turnkey capabilities to both the nuclear and
chemical industries. The chemical industry is embarking on a self regulated
program to assess vulnerability to physical and cyber security at chemical
plants and implement the necessary security enhancements. Services offered by
the Company's team include threat and vulnerability assessments, risk mitigation
plans, cost/benefit analysis, security system design, implementation, testing
and training.

         The Company also believes it is uniquely qualified to apply its plant
design and operations knowledge as well as simulation technology to help
customers analyze security threats and develop strategies to test plant recovery
strategies in the event of an accident.

         Process Control Business

         The Company's Process Solutions Group is continuing its efforts to
introduce product enhancements that maintain the Company's competitive edge in
the marketplace. The Process Solutions Group has continued to concentrate on its
existing customer base while embarking on a major effort to expand channels to
market with a new version of its process automation system that leverages the
latest price advantaged technology. This entry level offering, D/3 Compact,
along with the most recent release of the software, D/3 Version 11.0, combines
the low cost found in programmable logic controllers (PLC) solutions with the
high functionality of a distributed control system. The small footprint and
lower cost of this new offering is only the tip of what the new software
capabilities include. Existing and new customers will find enhanced alarm
handling and improved security features with the use of D/3 Version 11.0 and D/3
Compact. This cost effective solution will enable existing customers to apply
automation to areas of their plants that could not previously afford the
benefits of a fully distributed control system.

         Furthermore, from a sales and marketing perspective, the Process
Solutions Group has expanded its sales channel by entering into agreements with
five manufacturers' representative organizations that will work in conjunction
with the existing direct sales group to cultivate new business, particularly in
smaller batch applications where previously the power of the D/3 could not be
financially justified. In support of the aggressive sales efforts, the Process
Solutions group has also initiated a number of marketing activities this year in
an effort to improve awareness of GSE Systems in the marketplace. Although the
D/3 family of technology products is superior to other offerings, many potential
new customers are not aware of the Company. Accordingly, the Process Solutions
Group has created an integrated marketing program to reach new customers which
includes:

*    designing  and  developing  new  corporate  brochures,  pamphlets and other
     marketing literature,
*    developing a new web site that was released in August,
*    launching  two direct mail  campaigns - one for existing  customers and the
     other for prospects in the specialtychemical,  pharmaceutical, and food and
     beverage industries,
*    launching  a public  relations  campaign  in an effort to use the media for
     awareness,
*    establishing a contract with ARC Advisory  Group, a leading analyst firm in
     the process manufacturing industry, and
*    launching a customer  reference program in an effort to document  successes
     with our loyal customer base.

         Contract Revenue. Total contract revenue for the three and nine months
ended September 30, 2002 totaled $10.6 million and $34.0 million, respectively,
as compared with total contract revenue of $13.8 million and $38.1 million for
the three and nine months ended September 30, 2001, respectively.

         The Process business unit's revenue was $5.1 million for the third
quarter 2002 compared with $8.3 million in the same quarter of 2001, a 38.0%
decrease; revenue for the nine months ended September 30, 2002 was $18.7 million
versus $17.7 million for the same period in 2001, a 5.7% increase. Revenue
generated from work performed for Westinghouse Savannah River Company (WSRC)
decreased from $5.4 million or 66% of total Process revenue in the third quarter
2001 to $2.0 million or 39% of total Process revenue in the third quarter 2002.
However, on a year-to-date basis, WSRC revenues have increased: $9.2 million or
49% of revenue for the nine months ended September 30, 2002 versus $8.4 million
or 47% of revenue for the same period in 2001. Included in 2001 revenue was
$507,000 related to Process' VirtualPlant business, which was sold to Avantium
International B.V. in March 2001.

         The Power business unit's revenue was $5.5 million for the third
quarter 2002 compared with $5.6 million in the same quarter of 2001, a 1.3%
decrease; revenue for the nine months ended September 30, 2002 was $15.2 million
versus $20.4 million for the same period in 2001, a 25.2% decrease. Although
there was increased activity in the U.S. nuclear upgrade market in the first
nine months of 2002 as compared to the prior year, international revenues have
decreased due to the completion of several large, multi-year projects. In
addition, several of GSE's international customers have delayed the award of
large orders that the Company has bid on in 2002.

         Gross Profit. Gross profit totaled $3.0 million (28.6% of revenue) for
the quarter ended September 30, 2002, as compared with $4.4 million (31.5% of
revenue) for the quarter ended September 30, 2001. For the nine months ended
September 30, 2002 and 2001, gross profit decreased from $10.6 million (27.8% of
revenue) in 2001 to $10.3 million (30.2% of revenue) in 2002. The reduction in
gross profit margins for the third quarter 2002 reflects the lower Process
revenues. The improvement in gross profit margins for the nine months ended
September 30, 2002 is mainly due to the sale of Process' VirtualPlant business
in March 2001 (this business had negative gross profit of $264,000 in the first
quarter 2001).

          Selling, General and Administrative Expenses. Selling, general and
administrative ("SG&A") expenses totaled $3.0 million in the quarter ended
September 30, 2002, a 4.7% increase from the $2.8 million for the same period in
2001. SG&A expenses for the nine months ended September 30, 2002 increased 10.8%
to $9.0 million in 2002 from $8.1 million for the same period of the prior year.
In the first quarter 2002, the Process business unit hired a new marketing
manager who has been charged with developing the business unit's marketing
strategy, revitalizing the Company's marketing collateral, and planning the
product introductions for the D/3 Version 11.0 and the new D/3 Compact. The
Power business has incurred higher bidding and proposal costs in the pursuit of
new orders and from the addition of two marketing personnel hired for its
security business in the beginning of 2002. In the third quarter 2002, the Power
Business Unit implemented a staff reduction; SG&A expense reflects $205,000 of
accrued severance, of which $177,000 had not been paid at September 30, 2002. In
addition, the Company incurred a significant increase in its net research and
product development expenditures ("R&D"), as discussed below.

         Gross R&D totaled $914,000 million in the third quarter of 2002, as
compared with $499,000 in the same period of 2001. Capitalized software
development costs totaled $651,000 and $282,000 for the third quarter of 2002
and 2001, respectively. Accordingly, net R&D expensed and included in SG&A was
$263,000 and $217,000 for the third quarter of 2002 and 2001, respectively.

         Gross R&D spending for the nine months ended September 30, 2002 and
2001 totaled $2.9 million and $1.2 million, respectively. Capitalized software
development costs totaled $2.2 million in 2002 versus $584,000 in the same
period of 2001; and net R&D expensed and included in SG&A was $715,000 for the
nine months of 2002 versus $624,000 in 2001.

     The increase in the Company's capitalized software development expenditures
     was related to:

*    The development of Version 11.0 of its D/3 Process  Automation  System. The
     major  enhancements  to the system  include  improved  alarm  handling  and
     advanced system  diagnostics.  In addition,  the Company introduced two new
     more cost effective process controllers based on the use of modern PCI back
     plane  technology and improved  diagnostics.  The project was completed for
     commercial release as of October 1, 2002.
*    The development of the Process D/3 Compact,  a smaller,  redesigned version
     of the D/3 distributed  control system which is aimed at smaller automation
     applications.  This entry-level offering will combine the low cost found in
     Programmable  Logic Controllers (PLC) solutions with the high functionality
     of a distributed  control system.  The project was completed for commercial
     release as of October 1, 2002.
*    The replacement of the Graphic User  Interfaces  (GUI) for our Power GSuite
     and  Topmeret  tools  with a Java based GUI,  which will  provide  platform
     independence and internet enabling. The project is expected to be completed
     and ready for commercial release by January 1, 2003.

         Depreciation and  Amortization.  Depreciation  expense totaled $137,000
and  $197,000   during  the  quarters   ended   September  30,  2002  and  2001,
respectively. For the nine months ended September 30, 2002 and 2001 depreciation
expense   totaled   $379,000  and  $562,000,   respectively.   The  decrease  in
depreciation  in 2002 as compared to the same  periods in 2001 is due to certain
assets becoming fully depreciated.

         Due to the Company's adoption of SFAS No. 142 "Goodwill and Other
Intangible Assets" on January 1, 2002, goodwill is no longer amortized, but is
subject to an annual test of impairment. Thus, the Company recognized $167,000
of goodwill amortization in the third quarter 2001 versus none in the third
quarter 2002. For the nine months ended September 30, 2001, the Company
recognized $503,000 of goodwill amortization versus none for the nine months
ended September 30, 2002. See Footnote 10, "Goodwill" in the Notes to
Consolidated Financial Statements.

         Operating Income (Loss). The Company had operating loss of $72,000
(0.7% of revenue) in the third quarter 2002, as compared with an operating
income of $1.2 million (8.4% of revenue) for the same period in 2001. For the
nine months ended September 30, 2002 and 2001, operating income was $873,000
(2.6% of revenue) and $1.4 million (3.7% of revenue), respectively.

         Gain on Sale of Assets. On March 6, 2001, the Company sold its
VirtualPlant business technology and assets to Avantium International B.V. in
exchange for Avantium's stock and recognized a gain on the sale of $3.3 million,
before income taxes. This gain was determined based on the estimated fair market
value of the Avantium stock received, based on an independent appraisal, less
the book value of the assets sold, approximately $700,000 in severance costs
payable to certain former employees of VirtualPlant that were not hired by
Avantium, and other transaction expenses. See Footnote 5, "Investment in
Avantium International B.V." in the Notes to Consolidated Financial Statements.

         Interest Expense, Net. Net interest expense decreased 70.6% from
$235,000 in the quarter ended September 30, 2001 to $69,000 for the same quarter
in 2002. This decrease is due to lower interest rates in the third quarter 2002
versus 2001 (5.50% average and 7.25% average, respectively), a reduction in the
average bank debt outstanding ($3.6 million average for the third quarter 2002
versus $6.2 million average for the third quarter 2001), and a reduction in the
average balance outstanding on the Company's subordinated debt to ManTech
($650,000 average for the third quarter 2002 versus $4.9 million average for the
third quarter 2001).

          For the nine months ended September 30, 2002 and 2001, net interest
expense totaled $204,000 and $687,000, respectively. Similar reductions in the
average interest rate and outstanding debt balances for the first nine months of
2002 as compared to the same period in the prior year accounted for the
reduction in interest expense.

         Other Income, Net. Other income, net for the three and nine months
ended September 30, 2002 reflects recognized foreign currency transaction gains
and royalty income. For the comparable periods in 2001, other income mainly
reflects the receipt of $147,000 equity distribution from the Company's
liquidated joint venture in China (this investment was written off in a prior
year) offset by net foreign currency transaction losses.

         Provision (Benefit) for Income Taxes. The Company's effective tax rate
is based on the best current estimate of its expected annual effective tax rate.
The difference between the statutory U.S. tax rate and the Company's effective
tax rate for the quarters ended September 30, 2002 and 2001 is primarily due to
the effects of foreign operations being taxed at different rates and state
income taxes. As of September 30, 2002 and December 31, 2001, the aggregate
deferred tax assets are recorded net of a valuation allowance of $4.9 million.


Liquidity and Capital Resources

         As of September 30, 2002, the Company's cash and cash equivalents
totaled $465,000 compared to $2.0 million at December 31, 2001.

         Cash from operating activities. Net cash used in operating activities
was $1.0 million for the nine months ended September 30, 2002. Significant
changes in the Company's assets and liabilities in 2002 included:

     *    a decrease in contract receivables of $1.6 million, largely related to
          the collection of receivables for Westinghouse Savannah River Company
          projects, and
     *    a $1.6 million reduction in billings in excess of revenues earned. The
          Company had  received  orders from two Process  customers in the third
          quarter 2001 that allowed GSE to invoice the customer in full prior to
          the work being  completed.  The  reduction  in  billings  in excess of
          revenues  earned  reflects  the  completion  of a portion of these two
          contracts during the first nine months of 2002.

         Net cash used in operating activities was $1.5 million for the nine
months ended September 30, 2001. The gain on the Company's sale of its
VirtualPlant technology and assets to Avantium International B.V. in March 2001
($3.3 million) was a non-monetary exchange that had no impact on the Company's
operating cash flow in 2001. Significant changes in the Company's assets and
liabilities in 2001 included an increase in contract receivables of $4.3
million, a $4.2 million reduction in accounts payable and accrued expenses, and
a $4.5 million increase in billings in excess of revenues earned. Accounts
receivable collections in early 2001 together with the $1.5 million received in
cash from ManTech through issuance of additional subordinated debt were used to
pay down vendor liabilities.

          Cash used in investing activities. Net cash used in investing
activities was $2.6 million in the first nine months of 2002, comprised of $2.2
million of capitalized software development costs and $424,000 for capital
expenditures. The Company expects spending on capitalized software development
costs and capital expenditures to decrease for the final quarter of 2002 as
compared with the spending in the first nine months of 2002, with forecasted
expenditures of $350,000.

         In the first nine months of 2001, net cash used in investing activities
was $926,000, consisting of $584,000 of capitalized software development costs
and $342,000 for capital expenditures.

         Cash provided by financing activities. During the nine months ended
September 30, 2002, the Company generated $2.0 million net cash through
financing activities. The Company received $1.3 million from its escrow agent in
January 2002 from a fixed-price rights offering which was completed on December
21, 2001 and received $262,000 from the exercise of employee stock options. The
Company decreased its borrowings under its bank line of credit by $1.3 million
to a total of $3.7 million, and decreased its borrowings from ManTech
International Corporation by $350,000 to a total of $650,000. The Company
entered into two contracts with a customer for the lease of certain hardware and
software under 36-month leases and assigned the payments due under these
sales-type leases to a third party financing company, receiving proceeds of $2.6
million. In addition, the Company issued a $168,000 bid bond that was cash
collateralized. Bid bonds are issued by the Company in the ordinary course of
business through banks as required by certain contracts and proposal
requirements.

         Cash generated by financing activities was $1.9 million in the nine
month period ended September 30, 2001. In 2001, the Company reduced its
borrowings under its bank line of credit by $1.1 million to a total of $8.1
million, but increased its borrowings from ManTech by $3.4 million to a total of
$4.9 million.


Credit Facilities

         The Company has a $10.0 million bank line of credit with a bank which
expires on March 23, 2003. The credit facility provides for borrowings up to a
total $10.0 million to support working capital needs and foreign letters of
credit. At September 30, 2002, the Company's available borrowing base was $4.9
million, of which approximately $3.7 million had been utilized.

         The credit facility requires the Company to comply with certain
financial ratios on a monthly basis and precludes the Company from paying
dividends and making acquisitions beyond certain limits without the bank's
consent. As of July 31, 2002 and August 31, 2002, the Company was not in
compliance with one of its financial ratio covenants. The Company has received a
written waiver from the bank for its July and August noncompliance. At September
30, 2002, the Company was in compliance with all of the covenants.

         As of September 30, 2002, the Company has classified the borrowings
under the line of credit as current. See Note 6, "Long-term Debt", in the Notes
to Consolidated Financial Statements" for additional details about this line of
credit.

         On June 25, 2001, the Company issued an unsecured promissory note to
ManTech that allowed the Company to borrow up to $1.0 million at an interest
rate of prime plus one percent. The note is subordinated to the Company's credit
facility. In 2002, the Company repaid ManTech $350,000 of the note from the
proceeds of a fixed-price rights offering that was completed in December 2001.

         On December 5, 2001, ManTech elected to convert $3.9 million of
subordinated debt into Series A convertible preferred stock at a conversion rate
of $100 per share. The Series A convertible preferred stock has no voting rights
and bears dividends at the rate of 6% per annum payable quarterly. Dividends
will accumulate if not paid quarterly and compounded interest will accrue on any
unpaid dividends. As of September 30, 2002, the Company had paid all dividends
due except for $117,000 for the second and third quarter 2002 which are included
in accrued expenses. ManTech at its discretion has the right to convert each
share of Series A convertible preferred stock into GSE common stock at a
purchase price of $2.645 per share at any time after a one-year holding period
from the date of issuance. At the end of the third year from the date of
issuance, the Series A convertible preferred stock automatically converts into
1,474,480 shares of GSE common stock. Prior to ManTech's conversion of the
Series A convertible stock to common stock, GP Strategies has the option to
acquire 50% of the Series A convertible preferred stock for $1,950,000.






Item 3.  Quantitative and Qualitative Disclosure 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 September 30, 2002, such interest
rates are based on the bank's prime rate plus 75 basis-points.

         As of September 30, 2002, $4.3 million of the Company's debt was
subject to variable interest rates. A 100 basis-point change in such rates
during the quarter ended September 30, 2002 and for the nine months ended
September 30, 2002 would have changed the Company's interest expense by
approximately $11,000 and $39,000, respectively.

Item 4.  Disclosure Controls
         Within ninety days prior to the filing of this quarterly report, an
evaluation was performed under the supervision and with the participation of the
Company's management, including the Chief Operating Officer (the "COO") and
Chief Financial Officer (the "CFO"), of the effectiveness of the design and
operation of the Company's disclosure controls and procedures. Based on that
evaluation, the Company's management, including the COO and CFO, concluded that
the Company's disclosure controls and procedures were effective. There have been
no significant changes in the Company's internal controls or in other factors
that could significantly affect internal controls subsequent to the evaluation.

              The Company filed a report on Form 8-K effective September 20,
              2002 regarding the following transactions:

              (a) On August 28, 2002, the registrant established an Executive
              Compensation Plan for Jerry Jen for 2002. Mr. Jen was appointed
              President on March 27, 2001. The Executive Compensation Plan for
              2002 is similar to the one established for Mr. Jen in 2001, as
              modified to reflect the company's 2002 financial forecast.

              (b) On August 30, 2002, the registrant accepted the resignations
              of Messrs. Feldman and Greenberg as executive employees. Messrs.
              Feldman and Greenberg will continue to receive annualized payments
              of $120,000 and $60,000, respectively, in their capacity as
              Executive Director I and Executive Director II, respectively,
              through December 31, 2002. The term for all Executive Directors I
              (Messrs. Feldman and Pedersen) and Executive Directors II (Messrs.
              Moore and Greenberg) will expire on December 31, 2002.
              Notwithstanding, Messrs. Feldman, Pedersen, Moore and Greenberg
              will continue to serve as directors of the company in accordance
              with applicable law. Effective January 1, 2003, Messrs. Feldman,
              Pedersen, Moore and Greenberg will receive the company's standard
              compensation for directors (unless otherwise modified by the
              independent directors or shareholders in accordance with
              applicable law).

I, Chin-Our Jerry Jen, certify that:
1.)  I have reviewed this quarterly report on Form 10-Q of GSE Systems, Inc.
     (the "Company");

2.)  Based on my knowledge, this quarterly report does not contain any untrue
     statement of a material fact or omit to state a material fact necessary to
     make the statements made, in light of the circumstances under which such
     statements were made, not misleading with respect to the period covered by
     this quarterly report;

3.)  Based on my knowledge, the financial statements, and other financial
     information included in this quarterly report, fairly present in all
     material respects the financial condition, results of operations and cash
     flows of the Company as of, and for, the periods presented in this
     quarterly report.

4.)  The Company's other certifying officers and I are responsible for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules 13a-14 and 15d-14) for the registrant and we have:

     a.)  designed  such  disclosure  controls  and  procedures  to ensure  that
          material   information   relating  to  the  Company,   including   its
          consolidated subsidiaries,  is made known to us by others within those
          entities,  particularly  during  the  period in which  this  quarterly
          report is being prepared;
     b.)  evaluated the effectiveness of the Company's  disclosure  controls and
          procedures  as of a date  within 90 days prior to the  filing  date of
          this quarterly report (the "Evaluation Date"); and
     c.)  presented  in  this  quarterly   report  our  conclusions   about  the
          effectiveness  of the disclosure  controls and procedures based on our
          evaluation as of the Evaluation Date;

5.)  The Company's other certifying officers and I have disclosed, based on our
     most recent evaluation, to the registrant's auditors and the audit
     committee of the registrant's board of directors (or persons performing the
     equivalent function):

     a.)  All  significant  deficiencies  in the design or operation of internal
          controls which could adversely affect the Company's ability to record,
          process,  summarize and report  financial data and have identified for
          the Company's  auditors any material  weaknesses in internal controls;
          and
     b.)  Any fraud, whether or not material,  that involves management or other
          employees  who  have a  significant  role  in the  Company's  internal
          controls; and

6.)  The Company's other certifying officers and I have indicated in this
     quarterly report whether or not there were significant changes in internal
     controls or in other factors that could significantly affect internal
     controls subsequent to the date of our most recent evaluation, including
     any corrective actions with regard to significant deficiencies and material
     weaknesses.
