                                 PROXY STATEMENT
                       FOR ANNUAL MEETING OF STOCKHOLDERS

         The Board of Directors is furnishing you this Proxy Statement to
solicit proxies on its behalf to be voted at the 2001 Annual Meeting of the
Stockholders of GSE Systems, Inc. (the "Company"). The meeting will be held at
10:30 a.m. local time, on Wednesday, May 30, 2001 at the Sheraton Columbia
Hotel, 10207 Wincopin Circle, Columbia, Maryland. The proxies may also be voted
at any adjournments or postponements of the meeting.

         The address of the Company's principal executive offices is 9189 Red
Branch Road, Columbia, Maryland, 21045. The proxy materials and the Company's
2000 Annual Report are first being sent to stockholders on or about May 1, 2001.

         All properly executed written proxies that are delivered pursuant to
this solicitation will be voted at the meeting in accordance with the directions
given in the proxy unless the proxy is revoked before the meeting. You can
revoke your proxy by

          (a)       giving written notice to the Secretary of the Company,

          (b)       delivering a later dated proxy, or

          (c)       voting in person at the meeting.

         As a stockholder, you should specify your choice for each matter on the
enclosed form of proxy. If no instructions are given, proxies that are signed
and returned will be voted FOR the election of all Director nominees, FOR the
proposal to ratify the appointment of KPMG LLP, FOR the proposal to amend the
Certificate of Incorporation increasing GSE's authorized Common Stock from
8,000,000 shares to 18,000,000 shares, and FOR the proposal authorizing ManTech
to convert its debt into equity in the form of Convertible Preferred Stock.
Other matters that properly come before the meeting will be voted upon by the
persons named in the enclosed proxy in accordance with their best judgment.

         The Company will continue its long-standing practice of holding the
votes of all stockholders in confidence from Directors, officers and employees
except: (a) as necessary to meet applicable legal requirements and to assert and
defend claims for or against the Company; (b) in case of a contested proxy
solicitation; or (c) if a stockholder makes a written comment on the proxy card
or otherwise communicates his/her vote to management. The Company will, as it
has in the past, retain an independent tabulator to receive and tabulate the
proxies.





                  VOTING SECURITIES AND PRINCIPAL STOCKHOLDERS

Voting Securities

         Only stockholders of record at the close of business on April 13, 2001
will be entitled to vote at the Annual Meeting or at adjournments or
postponements of the meeting. On April 13, 2001, there were 5,193,527 shares of
common stock issued and outstanding. Each share of common stock is entitled to
one vote on all matters that may properly come before the Annual Meeting.

         The presence in person or by proxy at the Annual Meeting of the holders
of at least a majority of the total number of outstanding shares of common stock
will constitute a quorum for the transaction of business.

         Shares of common stock represented by a properly signed and returned
proxy will be counted as present at the Annual Meeting for purposes of
determining a quorum, without regard to whether the proxy is marked as casting a
vote or abstaining.

         Directors are elected by a plurality of the votes cast. A withheld vote
will not affect the required plurality. All other matters to come before the
Annual Meeting require a majority vote in person or by proxy. Therefore,
abstentions will have the same effect as votes against the proposals on such
matters.

         Brokers who hold shares of common stock in street name may not have the
authority to vote on certain matters for which they have not received voting
instructions from beneficial owners. Such broker non-votes, although present for
quorum purposes, will be deemed shares not present to vote on such matters and
will not be included in calculating the number of votes necessary for approval
of such matters.

Security Ownership of Certain Beneficial Owners and Management

         The following table sets forth information regarding beneficial
ownership of the Company's common stock, as of April 13, 2001, by: (i) each
stockholder who is known by the Company to own beneficially more than five
percent of the outstanding common stock, (ii) each of the Company's Directors,
(iii) each executive officer of the Company named in the Summary Compensation
Table, and (iv) all Directors and executive officers of the Company as a group.
Except as otherwise indicated below, the Company believes that the beneficial
owners of the common stock listed below have sole investment and voting power
with respect to such shares, subject to community property laws where
applicable.

         In preparing the following table, the Company has relied on the
information contained in the Statements on Schedule 13G previously filed by
ManTech and GP Strategies Corporation ("GP Strategies"), and Schedule 13G/A
filed for 2000 by Benson & Associates LLC. Certain of the shares reported in the
following table may be deemed to be beneficially owned by more than one person
and therefore may be included in more than one table entry.

____________________________________

                        PROPOSAL 1: ELECTION OF DIRECTORS

         The stockholders elect at least one-third of the members of the Board
of Directors (the "Board") annually. The Directors are divided into three
classes. Each class serves for a period of three years, although a Director may
be elected for a shorter term in order to keep the number of Directors in each
class approximately equal. This practice is in accordance with the Company's
Amended and Restated Certificate of Incorporation.

         The terms of Jerome I. Feldman and George J. Pedersen will expire at
the 2001 Annual Meeting. Messrs. Feldman and Pedersen have been nominated to
stand for reelection at the meeting to hold office until 2004 and until their
successors are elected and qualified.

         On March 10, 2000 the Board increased the number of Directors to eight
  and elected Joseph W. Lewis as a Director to serve until the 2000 Annual
  Meeting. Mr. Lewis was elected at the 2000 Annual Meeting to hold office until
  2003 and until his successor has been elected and qualified.

         On March 22, 2000 the Board increased the number of Directors to nine
  and elected Brian K. Southern as a Director to serve until the 2000 Annual
  Meeting. Mr. Southern was elected at the 2000 Annual Meeting to hold office
  until 2002 and until his successor has been elected and qualified. On March 8,
  2001, Mr. Southern resigned from the Board.

         On March 26, 2001, Christopher M. Carnavos resigned from the Board. The
  Board anticipates filling this vacancy by June 14, 2001 with an independent
  director in order to meet Amex requirements for the Audit Committee.

         On March 27, 2001 the Board elected Chin-Our Jerry Jen as a Director to
  serve the vacancy created by Mr. Southern's resignation and to hold office
  until 2002 and until his successor has been elected and qualified.

         The proxies solicited hereby, unless directed to the contrary, will be
voted for election of the nominees. All of the nominees have consented to being
named in this Proxy Statement and to serve if elected. The Board has no reason
to believe that any of the nominees will not be a candidate or will be unable to
serve, but if either occurs proxies may be voted for such substituted nominee or
nominees as the Board, in its discretion, may designate.

Pedersen (Chairman), Jerome I. Feldman and formerly Christopher M. Carnavos. The
Executive  Committee  has the  authority  to  exercise  all powers of the Board,
except  for  actions  that must be taken by the full  Board  under the  Delaware
General Corporation Law. The Executive Committee met twice during 2000.

         Audit Committee. The Audit Committee consists of Sheldon L. Glashow and
Joseph W. Lewis. The Audit Committee makes recommendations concerning the
engagement of independent public accountants, reviews with the independent
public accountants the plans and results of the audit engagement, approves
professional services provided by the independent public accountants, reviews
the independence of the independent public accountants and reviews the adequacy
of the Company's internal accounting controls. The Audit Committee met twice
during 2000. In accordance with Amex requirements, the Board will be appointing
a third member of the Audit Committee (i.e., a third independent Director) by
June 14, 2001.

          Nominating  Committee.  The Nominating Committee consists of Jerome I.
Feldman, George J. Pedersen and formerly Christopher M. Carnavos. The Nominating
Committee  selects and  recommends  nominees  for  election as  Directors of the
Board. The Nominating Committee did not meet during 2000.

          Compensation Committee.  The Compensation Committee consists of Jerome
I. Feldman,  George J. Pedersen (Chairman) and formerly Christopher M. Carnavos.
The Compensation  Committee is responsible for determining  compensation for the
Company's executive officers and for administering and granting awards under the
Company's Long-Term Incentive Plan (the "Plan"). The Compensation  Committee met
five times during 2000. See "Report of the Compensation Committee", below.

Compensation of Directors

         The Board pays its members who are not employees of the Company (the
"Non-Management Directors") an annual fee of $5,000 for their service and $1,500
for each Board meeting attended. Officers who are full-time employees and are
also Directors do not receive any fee or remuneration for services as members of
the Board of Directors or any Board Committee.

         At the discretion of the Board, each person who becomes a
Non-Management Director may receive an initial grant of options under the Plan
to purchase shares of common stock having an exercise price per share equal to
the fair market value of a share of common stock on the date such person first
becomes a Non-Management Director. Also at the discretion of the Board, under
the Plan, each Non-Management Director serving as a Director on December 31 of
each calendar year (commencing in 1995) may receive options to purchase shares
of common stock with an exercise price per share equal to the fair market value
of a share of common stock on such date. Usually, options granted under the Plan
to Non-Management Directors become exercisable in three installments with 40%
vesting on the first anniversary of the date of grant and 30% vesting on each of
the second and third anniversaries of the date of grant, subject to acceleration
under certain circumstances such as a change of control.

         In 2000, Messrs. Glashow, Lewis and Schefler were each granted options
to purchase 10,000 shares of common stock at an exercise price of $7.50. Messrs.
Carnavos and Southern were each granted options to purchase 100,000 shares of
common stock at an exercise price of $4.75.

         In 1999, the Company entered into employment agreements with Messrs.
Feldman, Greenberg, Pedersen and Moore to serve as executives, providing
strategic planning in acquisitions and divestitures, management of financing
arrangements, and customer and other business development activities. Salaries
paid under these agreements in 2000 were $120,000 each to Messrs. Feldman and
Pedersen and $60,000 each to Messrs. Greenberg and Moore.

         In 1999, as a management employee incentive, Messrs. Feldman and
Pedersen were each granted options to purchase 100,000 shares of common stock at
an exercise price of $3.3125; Messrs. Greenberg and Moore were each granted
options to purchase 50,000 shares of common stock at an exercise price of
$3.3125. These options have a Target Stock Value and vest immediately following
a 30-day trading-day period in which the Target Stock Value has been met or
exceeded (Target Stock Value of $8.00, 35% vested; Target Stock Value of $10.00,
100% vested), or vest at 100% on the fifth anniversary of the date of grant.
Messrs. Glashow and Schefler were each granted options to purchase 1,500 shares
of common stock at an exercise price of $3.3125.

95,000 shares of common stock were granted to seven (7) other employees during

the expiration of their term using 5% and 10% appreciation rates set by the SEC,
compounded annually and, therefore, are not intended to forecast possible future

                      REPORT OF THE COMPENSATION COMMITTEE

          This report  addresses the  compensation  of the  Company's  executive
officers  for the  last  fiscal  year  and the  Company's  general  compensation
philosophy.   The   Compensation   Committee  is  responsible   for  determining
compensation for the Company's  executive officers and for granting awards under
and  administering  the Company's  Long-Term  Incentive  Plan. The  Compensation
Committee  consists  of  Jerome I.  Feldman,  George J.  Pedersen  and  formerly
Christopher M. Carnavos.

Compensation Philosophy

     The compensation program for the executive officers of the Company and its
subsidiaries is developed and administered by the Board and its Compensation
Committee. General overall compensation policies regarding other officers and
employees of the Company are established by the Compensation Committee, but the
specific compensation program for such persons is developed and administered by
Company management. The key goals of the Company's compensation program are to
attract, retain and reward the most capable executives and other employees who
can contribute (both short and long-term) to the success of the Company and to
align compensation with the attainment of the business objectives of the
Company.

Compensation of Principal Executive Officer

     For 2000, Mr. Carnavos earned $228,600 in salary and bonus, as shown in the
Summary Compensation Table. The Committee considered this level of payment
appropriate in view of Mr. Carnavos' leadership of the Company. Mr. Carnavos
served as the principal executive officer within the Company and in this role
directed the Company's evolution beginning in 1999 from a traditional
supplier-vendor relationship to a more focused solution-oriented partnership
with the Company's customers, a partnership based on the Company's core
capability to provide integrated real-time dynamic simulation and process
control solutions. This led to the Company's 1999 VirtualPlant initiative, a new
business strategy that continued into 2000 with extensive development and
investment. 1

Implementation Guidelines

     To implement the compensation philosophy described above, the Company's
executive compensation program has three primary components: (i) a base salary,
(ii) bonus awards, and (iii) long-term incentive awards. The factors and
criteria to be considered with respect to each of these components are set forth
below.

     Base Salary. The range of the base salary for an executive or other
employee position will generally be established based on competitive salaries
for positions with a similar scope of responsibilities and job complexities. The
level of base salary within the range of competitive salaries will be determined
on the basis of individual performance, experience and other relevant factors,
such as demonstrated leadership, job knowledge and management skills. Such
determination will be made by the Compensation Committee, with regard to the
Company's executive officers, and by management with regard to all other
officers and employees consistent with the general overall compensation policies
established by the Compensation Committee.
________________________
1  On March 6, 2001, the Company sold its VirtualPlant business to Avantium
International B.V. ("Avantium") in exchange for an increased equity position in
Avantium.  For further details, see the Annual Report on Form 10-K filed by the
Company with the SEC for the fiscal year ended December 31, 2000 and the
Company's press release dated March 12, 2001.


     Base salaries will be targeted within the appropriate competitive range,
although higher compensation may be paid if necessary or appropriate to attract
or retain unusually qualified executives. Annual or other base salary
adjustments will be based on individual performance as well as other market
factors. Base salary payments made in 2000 were made to compensate ongoing
performance throughout the year.

     Bonus Awards. The bonus award is intended to focus the efforts of the
executives and other employees on performance objectives in accordance with the
business strategy of the Company.

     The Compensation Committee will administer incentive awards for the
Company's executive officers. The Compensation Committee will review and assess
the extent to which the overall Company performance goals have been met during
the year and make such awards to the Company's executive officers. Management of
the Company will be responsible for awarding bonus amounts to other officers and
employees of the Company, taking into account the general compensation
philosophy of the Company.

     For more information regarding the bonuses awarded in 2000 to the Company's
principal executive officer and the four other most highly compensated executive
officers of the Company, see "Compensation of Executive Officers -- Summary of
Cash and Certain Other Compensation."

     Long-Term Incentive Awards. The third element of the Company's compensation
program is provided through the Company's Long-Term Incentive Plan (the "Plan"),
which is designed to align the interests of the officers and employees with
those of stockholders. The Plan is intended to focus the efforts of officers and
employees on performance which will increase the value of the Company for its
stockholders.

     Pursuant to the Plan, the Compensation Committee may grant incentive stock
options within the meaning of the Internal Revenue Code of 1986, as amended, and
may grant, among other types of awards, nonstatutory stock options to purchase
shares of common stock. The Compensation Committee also may grant stock
appreciation rights and award shares of restricted stock and incentive shares in
accordance with the terms of the Plan. Subject to the terms of the Plan, the
Compensation Committee will have discretion in making grants and awards under
the Plan. The Compensation Committee may, however, consider the recommendations
of management with respect to such grants and awards.

     Total direct compensation to the Company's executive officers (base salary,
bonus awards and long-term incentive awards) will be targeted within the
appropriate competitive range, although higher compensation may be paid if
necessary to attract or retain unusually qualified executives.

     The Compensation Committee's decisions concerning the specific 2000
compensation elements for individual executive officers were made within the
broad framework previously described and in light of each executive officer's
level of responsibility, performance, current salary, prior year bonus and other
compensation awards. In all cases, the Compensation Committee's specific
decisions regarding 2000 executive officer compensation were ultimately based
upon the Compensation Committee's judgment about the individual executive
officer's performance and potential future contributions, and about whether each
particular payment or award would provide an appropriate reward and incentive
for that executive officer to contribute to, and enhance, the Company's
performance.

     The Board, with the advice of the Compensation Committee, will reexamine
the Company's compensation philosophy and objectives periodically and determine
if changes should be considered.

Company's audited financial statements with management, which has primary
responsibility for financial statements. KPMG LLP, the Company's independent
auditor for 2000, is responsible for expressing an opinion on the conformity of
the Company's audited financial statements with generally accepted accounting
principles. The Audit Committee has discussed with KPMG LLP the matters that are
required to be discussed by the Statement on Auditing Standards No. 61
(Communications with Audit Committees). KPMG LLP has provided the Audit
Committee the written disclosures and the letter required by Independence
Standards Board Standard No. 1 (Independence Discussions with Audit Committees),
and the Audit Committee discussed with KPMG LLP that firm's independence. KPMG
LLP has not provided the Company with any non-audit services that would be
incompatible with that firm's independence.

     Based on the considerations referred to above, the Audit Committee
recommended to the Board of Directors that the audited financial statements be
included in the Company's Annual Report on Form 10-K filed with the SEC for the
fiscal year ended December 31, 2000 and that KPMG LLP be appointed independent
auditors for the Company for 2001. The foregoing report is provided by the
following independent Directors, who constitute the Audit Committee:

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

       The Compensation Committee of the Company is currently comprised of Mr.
Pedersen, who is the Chairman of the Compensation Committee, and is President,
Chairman of the Board and Chief Executive Officer of ManTech; and Mr. Feldman,
who is Chairman of the Board of the Company's Board of Directors and is
President and Chief Executive Officer of GP Strategies.

       The Compensation Committee acts on matters related to other Directors,
executive officers and related entity proposals. Any matter related to a member
of the Committee requires ratification by the Non-Management Directors or
approval of the entire Board.

       On March 23, 2000, the Company entered into a new loan and security
agreement with a financial institution (the "bank") for a new credit facility
with a maturity date of March 23, 2003. In connection with the new credit
facility, ManTech provided a one-year $900,000 standby letter of credit to the
bank as additional collateral for the Company's facility. In addition, GP
Strategies provided a limited guarantee totaling $1,800,000; ManTech provided 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.
The Company was allowed to borrow up to 100% of the value of these two letters
of credit.

          In the fourth quarter of 2000, the Company issued a demand promissory
note to ManTech 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 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. On April 4,
2001, ManTech allowed the Company's bank to draw upon the two outstanding
letters of credit which were being used by the Company as additional collateral
for the Company's credit facility, thus paying down $1.8 million of the
Company's borrowings under the credit facility. The Company amended the
subordinated promissory note to ManTech, increasing the amount by $1.8 million
to a total of $3.9 million.

       On January 27, 2000, the Company issued 116,959 shares of its common
stock to ManTech for $500,000. The proceeds of the stock issuance were used for
working capital.

              PROPOSAL 2: INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

      The Board, upon the recommendation of the Audit Committee, and subject to
stockholder approval, has appointed the firm of KPMG LLP as independent auditors
of the Company for the current fiscal year. The Board has been advised by KPMG
LLP that neither the firm nor any member of the firm has a direct or indirect
financial interest in the Company or its subsidiaries.

      KPMG LLP became the Company's independent auditors on March 17, 2000,
replacing PricewaterhouseCoopers. During 2000, KPMG LLP billed the Company for
the following fees:

         Audit Fees.....................................................$50,000
         Financial Information Systems Design and Implementation Fees.....   $0
         All Other Fees.................................................$96,000

      A representative of KPMG LLP will be present at the Annual Meeting and
will have an opportunity to make a statement if he/she desires to do so and will
be available to respond to appropriate questions from stockholders.

      Ratification of the appointment of the independent auditors requires the
affirmative vote of a majority of the votes cast by the holders of the shares of
common stock voting in person or by proxy at the Annual Meeting. If the
stockholders do not ratify the appointment of KPMG LLP, the Board of Directors
will reconsider the appointment.

                  THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR
                               THE RATIFICATION OF
               THE APPOINTMENT OF KPMG LLP AS INDEPENDENT AUDITORS

PROPOSAL 3: AMENDMENT TO THE CERTIFICATE OF INCORPORATION INCREASING THE SHARES
                           OF AUTHORIZED COMMON STOCK

         The Board proposes that the stockholders approve an amendment to the
Certificate of Incorporation increasing the Company's authorized Common Stock
from 8,000,000 shares to 18,000,000 shares (an increase of 10,000,000 shares).
The Board has approved the amendment, subject to stockholder approval.

         The Company currently has the authority to issue 8,000,000 shares of
Common Stock with a par value of $0.01 each. As of April 13, 2001, there were
5,193,527 shares issued and outstanding. Combined with the options granted under
the Company's Long-Term Incentive Plan (1,486,655), options granted outside of
the Company's Long-Term Incentive Plan (42,500) and the warrants granted
(405,000), the number of authorized shares currently remaining for issuance is
872,318. Except for the purposes described in Proposal 4, there is no intended
current use for these new shares. The authority to issue these additional shares
is recommended to ensure an adequate supply of authorized unissued shares for
future business operations including, but not limited to, the issuance of
options to attract and retain executive personnel, key employees, directors,
consultants and advisors.

                THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE
                  AMENDMENT TO THE CERTIFICATE OF INCORPORATION
          INCREASING THE AUTHORIZED COMMON STOCK FROM 8,000,000 SHARES
                              TO 18,000,000 SHARES

         PROPOSAL 4: TO APPROVE A CONVERSION OF THE DEBT HELD BY MANTECH
        INTERNATIONAL CORPORATION INTO EQUITY IN THE FORM OF CONVERTIBLE
                                 PREFERRED STOCK

         As previously mentioned under the section "Compensation Committee
Interlocks and Insider Participation," ManTech has loaned the Company
$3,900,000. ManTech has proposed to convert its debt into equity in the form of
Convertible Preferred Stock. This proposal is outlined in Appendix B of this
Proxy Statement. The preferences of this Convertible Preferred Stock are as
stated in the proposal. As stated therein, ManTech is acquiring the Convertible
Preferred Stock for investment for its own account and not with a view to, or
for sale in connection with, any distribution thereof or with any intention of
disposing of the same or any interest therein. In the event ManTech converts the
Convertible Preferred Stock to Common Stock, or upon the expiration of the
three-year conversion period, the Convertible Preferred Stock will convert into
2,405,180 shares of Common Stock. The Board recommends approval of this proposal
as a viable means of eliminating $3,900,000 of subordinated debt. Shareholders
ManTech and GP Strategies will be voting FOR this proposal.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE CONVERSION OF
      MANTECH'S DEBT INTO EQUITY IN THE FORM OF CONVERTIBLE PREFERRED STOCK

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

       Section 16(a) of the Securities Exchange Act of 1934, as amended,
requires the Company's officers and directors, and persons who beneficially own
10% of the Company's common stock (the "Reporting Persons"), to file reports
regarding their Company common stock ownership and changes in ownership with the
SEC. Based solely on a review of the copies of such forms furnished to the
Company and written representations from certain of the Reporting Persons, the
Company believes that during 2000 the Reporting Persons complied with all
Section 16(a) reporting requirements applicable to them.

                                 OTHER BUSINESS

       The Company does not presently know of any matters that will be presented
for action at the Annual Meeting other than those set forth herein. If other
matters properly come before the meeting, proxies submitted on the enclosed form
will be voted by the persons named in the enclosed form of proxy in accordance
with their best judgment.

                                 ANNUAL REPORTS

       The Annual Report on Form 10-K filed by the Company with the SEC for the
fiscal year ended December 31, 2000 was filed on April 2, 2001. Also enclosed is
the Company's 2000 Annual Report to Stockholders. The Company shall furnish
copies of exhibits for a reasonable fee (covering the expense of furnishing
copies) upon written request to the attention of the Corporate Secretary, GSE
Systems, Inc., 9189 Red Branch Road, Columbia, Maryland 21045.

                              STOCKHOLDER PROPOSALS

       In accordance with rules promulgated by the SEC, any stockholder who
wishes to submit a proposal for inclusion in the proxy materials to be
distributed by the Company in connection with the Annual Meeting of Stockholders
in 2002 must do so no later than December 31, 2001.

       In addition, in accordance with the Company's Bylaws, in order for a
stockholder proposal to be properly brought before the 2002 Annual Meeting, a
stockholder submitting a proposal must file a written notice with the Corporate
Secretary which conforms to the requirements of the Bylaws. If the Board or a
designated committee or the officer who will preside at the stockholders'
meeting determines that the information provided in such notice does not satisfy
the informational requirements of the Bylaws or is otherwise not in accordance
with law, the stockholder will be notified promptly of such deficiency and be
given an opportunity to cure the deficiency within the time period prescribed in
the Bylaws. Such notice of a stockholder proposal must be delivered not less
than 60 days nor more than 90 days prior to the date of the Annual Meeting to be
held in 2002.

                                            By Order of the Board of Directors

Appendix B


The following are the major features of the proposed Convertible Preferred
Stock.

Par Value:        $.01 per share

Purchase Price:   $100.00 per share

Number of Shares: 39,000


Dividends:  The Convertible Preferred Stock will bear dividends
at the rate of 6% per annum on its $100.00 purchase price per share payable
quarterly. Dividends will accumulate if not paid quarterly and compounded
interest will accrue on any unpaid dividends.

Conversion to GSE Common Stock:  ManTech at its discretion shall
have the right to convert each share of Convertible Preferred Stock into GSE
Common Stock at a purchase price of $1.6215 per share at any time within three
years from the date of issuance of the Convertible Preferred Stock. Example: One
share of preferred stock at $100 divided by $1.6215 (purchase price of Common
Stock) equals 61.6713 shares of GSE Common Stock. This conversion option may
only be exercised upon providing GSE and GP Strategies Corporation (GPS) at
least ten days prior written notice. Upon the expiration of the three-year
conversion period, the Convertible Preferred Stock automatically converts into
GSE Common Stock upon the terms and conditions stated herein.

Restricted Securities:   ManTech acknowledges that the securities are not
registered with the SEC under the Securities Act of 1933 and, therefore, are
considered restricted securities in accordance with Rule 144. The Convertible
Preferred Stock cannot be offered for sale or sold except as specifically stated
herein.

Liquidation Preference:  In the event of liquidation or dissolution of GSE,
payment of available funds shall be made on the Preferred Stock (including
payment in satisfaction of dividend obligations) prior and in preference to
other outstanding classes of stock. However, all debt obligations must be
satisfied before ManTech's investment return on the Preferred Stock can be
realized.

Exemption from Registration  Requirements:  This transaction is intended to be a
private  issuance of securities  and,  therefore,  exempt from SEC  registration
requirements.   ManTech  is  acquiring  this  Convertible  Preferred  Stock  for
investment for its own account and not with a view to, or for sale in connection
with, any distribution thereof or with any intention of disposing of the same or
any interest therein.

Holding Period:  In accordance with Rule 144, ManTech agrees to a holding period
of at least one year from the date of the acquisition of the securities from
GSE.

Restrictive Legend:  The certificate or other document evidencing the securities
will contain a restrictive legend stating that the securities have not been
registered under the Securities Act of 1933 and setting forth or referring to
the restrictions on transferability and sale of the securities.

GPS Option: GPS has the option to acquire 19,500 shares (50%) of the Convertible
Preferred Stock under the following arrangement: (a) such option must be
exercised before ManTech exercises its option to convert the Convertible
Preferred Stock to GSE Common Stock, otherwise such option lapses; (b) GPS must
pay ManTech $1,950,000; (c) upon receipt of such payment, ManTech will transfer
19,500 shares of Convertible Preferred Stock to GPS; and (d) GPS acquires such
Convertible Preferred Stock under the same terms and conditions as ManTech,
except that the one-year holding period for GPS begins as of the date the option
is exercised.

Shareholder/Regulatory Approval: This transaction is contingent upon shareholder
and/or regulatory approval, as applicable. Upon such applicable approval(s),
ManTech, GPS and GSE will promptly negotiate in good faith a Definitive
Agreement.
