                       GSE SYSTEMS, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  September 30, 2000
                                   (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 generally accepted  accounting  principles 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  period  ended
December 31, 1999 filed with the Securities and Exchange Commission.

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 or warrants 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 was as follows:

                                                                                   

                                                        Three months ended            Nine months ended
                                                         September 30,                   September 30,
                                                       2000            1999           2000          1999
                                                       ----            ----           ----          ----
Weighted average shares outstanding - Basic           5,193,527     5,065,688       5,190,198    5,065,688
                                                      =========     =========       =========    =========
Weighted average shares outstanding - Diluted         5,193,527     5,065,688       5,190,198    5,239,756
                                                      =========     =========       =========    =========



For the three and nine months ended  September 30, 2000,  the number of weighted
average shares used for calculating  diluted loss per share is the same as basic
because the effect of potential  common  shares is  anti-dilutive  given the net
loss during both periods. The difference between the basic and diluted number of
weighted average shares outstanding for the nine months ended September 30, 1999
represents  dilutive  stock  options and  warrants to purchase  shares of common
stock computed  under the treasury stock method.


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 (in thousands):

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 approximately  $564,000 and $790,000
for the three  months ended  September  30, 2000 and 1999,  respectively.  Total
amortization  expense was  approximately  $589,000  and  $469,000  for the three
months ended September 30, 2000 and 1999, respectively.

For the nine months  ended  September  30, 2000 and 1999,  software  development
costs   capitalized   were   approximately   $1.6  million  and  $1.8   million,
respectively. Total amortization expense was approximately $1.7 million and $1.4
million for the nine months ended September 30, 2000 and 1999, respectively.

5. Investment in Avantium Technologies 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 $2.3 million,  and 352,102 shares
of Avantium common stock,  valued at $598,000.  The software  license,  which is
perpetual  in  nature,  gives  Avantium  the  right to use the  software  in the
development  of new software  products.  In the event new software  products are
developed,  the  Company  has the  first  right  of  refusal  to be the sole and
exclusive  distributors  of these  products in exchange for a 10% royalty.  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 nine months ended September 30, 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 nine  months  ended
September  30,  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.

6. Financing Arrangements

On March 23, 2000,  the Company  entered into a new loan and security  agreement
with a financial  institution  for a new credit facility with a maturity date of
March 23, 2003.  Borrowings from this facility were used to pay off the existing
debt under the Company's previous credit facility.

The new  agreement  established  a $10.0  million  line of credit  (the  "Credit
Facility") for the Company and its subsidiaries, GSE Process Solutions, Inc. and
GSE Power  Systems,  Inc,  jointly and  severally  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   Corporation  ("ManTech")  has  provided  two  separate  one-year
$900,000 standby letters of credit to the bank as additional  collateral for the
Company's credit facility.  GSE 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 September 30,  2000),  with interest only payments
due monthly.  At September 30, 2000, the Company's  available borrowing base was
approximately  $9.6  million,  of  which  approximately  $8.5  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 September 30,
2000, the Company was not in compliance with its minimum EBITDA (earnings before
interest,  taxes,  depreciation and amortization)  covenant, its minimum working
capital covenant, and its tangible net worth covenant.  Accordingly, the Company
has classified the borrowings under the Credit Facility as current.  The Company
has requested a written  waiver for these  covenants.  In the event such waivers
are not obtained, the bank could demand repayment of outstanding amounts.

Subsequent to September 30,2000,  restricted cash of $480,000 previously held as
collateral against the letter of credit was released by the bank.

7. Capital Stock

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.

8. 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 three  and nine  months
ended  September  30, 2000 and 1999 is  primarily  due to the effects of foreign
operations  being  taxed at  different  rates  and  state  income  taxes.  As of
September 30, 2000 and December 31, 1999, the aggregate  deferred tax assets are
recorded net of a valuation allowance of $1.1 million.

9. Segment Reporting

The Company is primarily  organized on the basis of two business units,  Process
and Power.  The Company  has a wide range of  knowledge  concerning  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  and  beverage,  and
pharmaceutical  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.

GSE evaluates the  performance  of its business units  utilizing "Business Unit
Contribution", which is substantially equivalent to earnings before interest and
taxes (EBIT) before allocating any corporate expenses.

10. Recent Pronouncements

In September 1998, the Financial  Accounting Standards Board issued FAS No. 133,
"Accounting for Derivative  Instruments and Hedging  Activities." This statement
requires  that  an  entity   recognize  all  derivatives  as  either  assets  or
liabilities in the statement of financial position and measure those instruments
at  fair  value.  In  September  1999,  FAS  137,   "Accounting  for  Derivative
Instruments  and Hedging  Activities  - Deferral of the  Effective  Date of FASB
Statement  No. 133 - an amendment  of FASB  Statement  No. 133" was issued.  The
Company  will be  required to adopt this new  accounting  standard on January 1,
2001.  The Company  does not believe  that the effect of the adoption of FAS No.
133 will be material.

12.  Subsequent Event

On  November  14,  2000,  the Company  announced  that it has signed a letter of
intent  whereby  Avantium  will  purchase  and  acquire  certain  assets  of the
Company's  VirtualPlant business,  under an asset purchase agreement,  in return
for an undisclosed  amount of shares in Avantium,  thereby rendering the Company
as Avantium's largest  shareholder.  The transaction is intended to be completed
by the end of 2000 and would include certain assets of the Company, intellectual
property  and  employment  of  certain  personnel.  The fair value of the shares
received from  Avantium  will exceed the carrying  value of the net assets sold.
The Company  became an equity  shareholder in Avantium at its founding (see Note
5, Investment in Avantium Technologies, B.V.).

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

General Business Environment
- ----------------------------

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
reducing the time-to-market for new product development; improving chemistry for
producing products; improving quality, safety and throughput; reducing operating
expenses; and enhancing overall productivity.

The Power business unit results continue to be strong,  as the Company maintains
its dominant market position in the nuclear power simulation industry. Utilizing
its technical and project management  strengths,  the business unit has expanded
its  focus  to  include  the  fossil  power  market.  In the  third  quarter,  a
multi-million  dollar order was  received  for a full scope fossil  simulator in
India.  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.

The Company's  Process  business unit is beginning to see an upturn in the third
quarter  with a 79% increase in orders as compared to the second  quarter  2000,
and a 4%  increase  as  compared  to the  third  quarter  1999.  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.  This trend appears to be affecting  the entire  process
control  industry.  Accordingly,  the Company took steps at the end of the third
quarter  to  reduce  costs  in the  Process  business  unit to  ensure  at least
breakeven  results for the business unit for the remainder of 2000,  including a
personnel  reduction in August. The Company incurred a charge of $262,000 during
the third quarter with respect to these terminations. Despite these charges, the
increases in third quarter orders in combination  with the cost  reductions have
resulted in a return to  profitability  for the Process  Control  portion of the
business.  Management  currently believes the Process business unit's long-lived
assets can be recovered through  undiscounted cash flows.  However, in the event
that the Company is unable to improve the results of the Process  business unit,
the Company will need to consider the  write-down of such assets,  through asset
impairment charges in future periods.

In  1999,  the  Company  introduced  its new  business  and  marketing  strategy
VirtualPlant(TM).  VirtualPlant  combines the  benefits of real-time  simulation
with control systems to create a "living",  learning real-time representation of
an operating plant. VirtualPlant also allows 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. Based on sophisticated  simulation technologies and expert knowledge of
processing realities, VirtualPlant is a fully integrated, comprehensive strategy
including  software,  consulting  services and training  that energy and process
manufacturing   companies   can  use  to   dramatically   reduce   new   product
time-to-market,  minimize  development costs,  achieve greater  optimization and
improve overall profitability.

A significant step in implementing  the VirtualPlant  strategy was the Company's
participation  in the  February  2000  founding  of Avantium  Technologies  B.V.
("Avantium"),   a   Netherlands-based   high  technology  company  that  employs
high-speed  experimentation  and simulation  ("HSE&S")  technologies in contract
research  and  development  in the area of new product  development  and process
chemistry. GSE is an equity shareholder along with Shell International Chemical,
SmithKline Beecham,  W.R. Grace, three Dutch universities  (Technical University
of Delft,  Technical  University of Eindhoven,  and Twente University) and three
venture  capital  firms  (Alpinvest,   The  Generics  Group,  and  S.R.One,  the
SmithKline Beecham venture funding company).  Avantium  Technologies will deploy
HSE&S  techniques to rapidly discover and optimize new processes and products of
interest to the  petrochemicals,  fine chemicals and pharmaceutical  industries.
The Company's undiluted holdings in Avantium Technologies B.V. are approximately
10%;  after  taking into  consideration  the expected  dilutive  effect of stock
option plans, the Company's  diluted  ownership  percentage is anticipated to be
approximately 5%.

In the third quarter 2000, the Company  continued to make extensive  investments
in its  VirtualPlant  business,  in both the product  development  and sales and
marketing efforts. These investments have contributed to the net losses reported
for the third quarter 2000 and year-to-date September 30, 2000.

On  November  13,  2000,  the Company  announced  that it has signed a letter of
intent  whereby  Avantium  will  purchase  and  acquire  certain  assets  of the
Company's  VirtualPlant business,  under an asset purchase agreement,  in return
for an undisclosed  amount of shares in Avantium,  thereby rendering the Company
as Avantium's largest  shareholder.  The transaction is intended to be completed
by the end of 2000 and would include certain assets of the Company, intellectual
property  and  employment  of  certain  personnel.  The fair value of the shares
received from  Avantium  will exceed the carrying  value of the net assets sold.
The Company  became an equity  shareholder in Avantium at its founding (see Note
5, Investment in Avantium Technologies, B.V.).

Revenue. Revenue for the three and nine months ended September 30, 2000 amounted
to $13.7 million and $42.1 million,  respectively,  as compared with revenues of
$15.6 million and $51.2  million for the three and nine months ended  September
30, 1999.  Process business unit year-to-date 2000 revenues are 29.2% lower than
the same period in the prior year. After making significant investments in their
process  control systems in 1998 and the first half of 1999, many customers have
opted to  reduce or  postpone  additional  investments.  The  Company's  Process
business  unit is  beginning  to see an upturn in the third  quarter  with a 79%
increase in orders as compared to the second  quarter 2000, and 4% increase over
orders received in the third quarter 1999. Included in the Process business unit
revenue for the nine months ended  September  30, 2000 was $2.9 million from the
sale of licenses for five of GSE's  software  products to Avantium  Technologies
B.V.  ("Avantium"),  including the object and source  codes,  in exchange for an
equity  interest in Avantium.  See Note 5,  Investment in Avantium  Technologies
B.V. in the Notes to Consolidated  Financial Statement,  above, for a discussion
of this  transaction.  The Power  business  unit  revenue for the three and nine
months  ended   September   30,  2000  was  $7.0  million  and  $22.2   million,
respectively,  as compared to $7.4  million and $23.0  million for the three and
nine months ended September 30, 1999.

Gross Profit.  Gross profit decreased to $3.7 million (26.8% of revenue) for the
three months ended  September 30, 2000 from $5.3 million  (34.0% of revenue) for
the  corresponding  period in 1999.  The  decrease in gross  profit is primarily
related to the  results  of the  Process  business  unit.  In 2000,  much of the
Process  business  unit  revenue  has  been  generated  through  service-related
revenues,  such as engineering services,  contract maintenance,  and spare parts
sales,  as compared to higher margin  upgrade  projects in 1999,  resulting from
customer  concerns  about  Y2K  date  issue.   Year-to-date  2000  gross  profit
percentage  was higher  than that for the third  quarter  2000 mainly due to the
sale of the licenses to Avantium earlier in the year.

Selling,   General   and   Administrative   Expenses.   Selling,   general   and
administrative  ("SG&A") expenses totaled $4.5 million in the three months ended
September 30, 2000, a 23.7% decrease from the corresponding period in 1999. This
decrease, excluding research and development costs which are discussed below, is
attributable to (1) lower sales and marketing  personnel and travel costs in the
Process business unit caused by lower headcount, (2) lower sales commissions due
to lower  Process  business  unit orders,  and (3) reduced  relocation  expenses
related to new hires.  These  reductions  have been offset in part by  increased
marketing and selling  expenses related to the  implementation  of the Company's
VirtualPlant  business  strategy.  For the nine months ended September 30, 2000,
SG&A expenses  were $3.8 million lower than the same period in 1999,  due to the
same  reasons  sited above plus a Power  business  unit refund of  approximately
$759,000 from the Swedish  Government  for a distribution  of a surplus  created
from strong  investment  returns on  contributions  made to the Social  Security
Program in Sweden during the last several years.

Gross research and product  development  expenditures  approximated $1.1 million
and $1.6 million for the quarters  ended  September  30, 2000 and  September 30,
1999.  Capitalized  software development costs totaled $534,000 and $790,000 for
the third quarters of 2000 and 1999, respectively; accordingly, net research and
development costs expensed and included in SG&A were approximately  $536,000 and
$810,000 for the three-month  periods ended September  30,2000 and September 30,
1999  respectively.  During the third  quarter 2000,  the Company  completed the
development  of  its  VPbatch  (TM)  product,  the  Windows  NT  version  of its
FlexBatch(R)  Recipe  and  Process  Management   software,   and  continued  the
development of version 10.2 of the Company's D/3 Distributed  Control System. In
addition, the Company continued development  initiatives to improve product ease
of use of all of its process  simulation  products and tightly  couple them into
the  VirtualPlant  architecture.  For the nine months ended  September 30, 2000,
gross  research  and  product  development  expenditures,  capitalized  software
development  costs, and net research and development costs expensed in SG&A were
$3.3 million, $1.6 million and $1.7 million, respectively,  versus $4.0 million,
$1.8 million and $2.2, respectively for the comparable period in 1999.

Depreciation  and  Amortization.  Depreciation  expense amounted to $267,000 and
$314,000  during the three months ended  September  30, 2000 and  September  30,
1999,  respectively.  During  the  nine  months  ended  September  30,  2000 and
September   30,  1999,   depreciation   expense  was   $888,000  and   $822,000,
respectively.

Amortization  of goodwill was $137,000 and $86,000 during the three months ended
September 30, 2000 and September 30, 1999, respectively.  During the nine months
ended  September  30, 2000 and  September  30,  1999,  amortization  expense was
$394,000 and $280,000,  respectively.  The increase in  amortization  during the
quarter and the nine-month period ended September 30, 2000 reflects the increase
in goodwill due to payments  made for  contingent  consideration  for prior year
acquisitions.

Operating  Income  (Loss).  Operating  income  (loss) for the three months ended
September  30,  2000  amounted to $(1.2)  million or (9.1%) of  revenue,  versus
($1.0) million or 6.5% of revenue for the corresponding  period in 1999. For the
nine months ended  September 30, 2000 and September 30, 1999,  operating  income
(loss) was  $(1.5)  million  or (3.6%) of  revenue  and $1.7  million or 3.2% of
revenue, respectively. The decrease for the quarter and nine-month period is the
result of the continuing  order slowdown in the Process  business unit offset by
lower selling, general and administrative costs. The Company began restructuring
the Process  business  unit in the third quarter 2000 to reduce costs and return
the business unit to  profitability.  Twenty-nine  personnel were terminated and
severance  costs of $262,000 were incurred in the third quarter 2000. In October
2000,   the  Company   entered  into  an  agreement  to  outsource  the  Process
manufacturing/assembly  functions.  Additional  severance costs of approximately
$100,000 will be incurred in the fourth quarter 2000.

Interest Expense,  Net. Net interest expense increased to $203,000 for the three
months ended  September 30, 2000 from $140,000 for the  corresponding  period 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  and higher  borrowing  costs.  For the nine months  ended
September 30, 2000 and September 30, 1999, net interest expense totaled $523,000
and  $271,000,  respectively.  Interest  expense  in 1999 was  offset by $60,000
interest income related to a note receivable.

Other  Income  (Expense).  Other income  (expense)  mainly  reflects  recognized
foreign currency transaction gains and losses.

Provision  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
three and nine months ended  September 30, 2000 and 1999 is primarily due to the
effects of foreign  operations  being taxed at different  rates and state income
taxes.  As of September 30, 2000 and December 31, 1999,  the aggregate  deferred
tax assets are recorded net of a valuation allowance of $1.1 million.

Liquidity and Capital Resources
- -------------------------------

Net cash used by operating activities was $1.3 million for the nine months ended
September  30, 2000, as reported on the  Consolidated  Statements of Cash Flows.
The  Company's  $2.9  million   investment  in  Avantium   Technologies   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 a $2.0
million reduction in contract receivables, mainly due to the lower orders of the
Process  business unit in during 2000, and a $1,4 million  reduction in accounts
payable and accrued expenses.

Net cash used in investing activities for the first nine months of 2000 was $2.0
million and consisted of $1.6 million of capitalized  software development costs
and $389,000 of capital expenditures.

During the nine months ended  September  30, 2000,  the Company  generated  $2.4
million of net cash from  financing  activities.  In January  2000,  the Company
issued  116,959  shares  of  its  common  stock,   at  fair  value,  to  ManTech
International  Corporation  for $500,000.  Cash  generated from the common stock
issuance and utilization of the Company's line of credit was partially offset by
cash payments for contingent consideration for prior year acquisitions.

On March 23, 2000,  the Company  entered into a new loan and security  agreement
with a financial  institution  for a new credit facility with a maturity date of
March 23, 2003.  Borrowings from this facility were used to pay off 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 September 30,
2000, the Company's  available borrowing base was approximately $9.6 million, of
which  approximately  $8.5  million  had been  utilized.  See Note 6,  Financing
Arrangements,  in the Notes to Consolidated  Financial  Statements,  above,  for
additional details about this line of credit. When the Credit Facility was first
entered  into,  ManTech  International  Corporation  ("ManTech")  had 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  is also  used  as  additional
collateral  for the Company's  credit  facility.  GSE is allowed to borrow up to
100% of the value of these two letters of credit.

This new credit  line  requires  the Company to comply  with  certain  financial
ratios. At September 30, 2000 the Company was not in compliance with its minimum
EBITDA  (earnings  before  interest,   taxes,   depreciation  and  amortization)
covenant,  its minimum  working  capital  covenant,  and its  tangible net worth
covenant.  Accordingly,  the Company has  classified  the  borrowings  under the
Credit Facility as current. The Company has requested a written waiver for these
covenants.  In the event such  waivers are not  obtained,  the bank could demand
repayment of outstanding amounts.

Due mainly to the lower volume of the Process  business  unit over the last four
quarters,  the Company is currently  experiencing  limited operating cash flows.
Cost reduction efforts, including employee terminations and reduction of selling
and administrative expenses, were made in August 2000. Additionally, in November
2000, the Company has outsourced its Process  manufacturing/assembly  operations
and made  additional  reductions  in  personnel.  The Company is  continuing  to
investigate options to improve business profitability.

Subsequent to September 30, 2000,  restricted cash of $480,000,  previously held
as collateral against a letter of credit, was released by the bank.

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  rate on its
existing  line of credit.  Such  interest  rate is currently  based on the prime
rate.
