                                PROXY STATEMENT
                     FOR THE ANNUAL MEETING OF STOCKHOLDERS

     The Board of Directors is furnishing you this proxy statement and
accompanying proxy card to solicit proxies to be voted at the 2005 annual
meeting of the stockholders of GSE Systems, Inc. (the "Company"). The annual
meeting will be held at 11:00 a.m. local time on Thursday, June 16, 2005 at our
headquarters located at 9189 Red Branch Road, Columbia, Maryland. The proxies
may also be voted at any adjournments or postponements of the annual 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 2004
Annual Report are first being sent to stockholders on or about May 26, 2005.
     
     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 amend the Company's 1995 Long-Term Incentive Plan (as Amended and
Restated Effective April 5, 1999), and FOR the proposal to ratify the
appointment of KPMG LLP.  Other matters that properly come before the annual
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.

VOTING SECURITIES AND PRINCIPAL STOCKHOLDERS

Voting Securities

     Only stockholders of record at the close of business on May 6, 2005 will be
entitled to vote at the annual meeting or at any adjournments or postponements
thereof. On May 6, 2005, there were 8,999,706 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 May 6, 2005, by: (i) each stockholder who
is known by the Company to own beneficially more than 5% of the outstanding
common stock, (ii) each of the Company's directors, (iii) each current executive
officer of the Company named in the Summary Compensation Table, and (iv) all
directors and executive officers as a group. Except as otherwise indicated, 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.

     We are not aware of any material proceedings to which any of the parties
identified under (i), (ii) or (iii) above, or any associate thereof, is a party
adverse to the Company or any of its subsidiaries or has a material interest
adverse to the Company or any of its subsidiaries.

     In preparing the following table, the Company has relied on the information
contained in the statements previously filed by GP Strategies Corporation ('GP
Strategies"), and Schedule 13G/A filed for 2004 by Wells Capital Management,
Inc. 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 Board of Directors is divided into three classes that serve staggered
three-year terms and are nearly equal in number as possible. The stockholders
elect at least one class of directors annually. Each class generally 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 Certificate of Incorporation.

     All of the directors were previously elected by the stockholders except for
Andrea D. Kantor, John V. Moran and Douglas E. Sharp who were appointed to the
board in October 2003.

     The terms of Jerome I. Feldman, John V. Moran and George J. Pedersen will
expire at the 2005 annual meeting. These directors have been nominated by the
Company's Nominating Committee to stand for reelection at the meeting to hold
office until 2007 and until their successors are elected and qualified.

     The terms of Dr. Sheldon L. Glashow, Dr. Roger L Hagengruber and Chin-Our
Jerry Jen will expire at the 2005 annual meeting. These directors have been
nominated by the Company's Nominating Committee to stand for reelection at the
meeting to hold office until 2008 and until their successors are elected and
qualified.

     On October 21, 2003, the Board increased the number of directors from nine
to eleven and elected John V. Moran as a director to serve until the 2005 annual
meeting and elected Andrea D. Kantor and Douglas E. Sharp to serve until the
2006 annual meeting.

     On December 31, 2004, John A. Moore resigned from the board.
      
     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.

          THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF
                   JEROME I. FELDMAN, DR. SHELDON L. GLASHOW,
          DR. ROGER L. HAGENGRUBER, CHIN-OUR JERRY JEN, JOHN V. MORAN,

Board and Committee meetings. The Company is a "controlled company" pursuant to
the regulations of the American Stock Exchange since over 50% of the voting
power is held by GP Strategies. The Company has therefore elected to take
advantage of certain exceptions to the listing requirements of the American
Stock Exchange applicable to controlled companies, as discussed below, including
the requirement that (i) the Company have a majority of independent directors,
(ii) board nominations be made by an independent nominating committee or a
majority of the independent directors, and (iii) executive compensation be
determined by an independent compensation committee or majority of the
independent directors.

     The non-management directors meet periodically in executive session. The
executive sessions of non-management directors are to be presided over by the
director who is the Chairman of the committee responsible for the issue being
discussed. The Board intends to schedule at least two executive sessions of
non-management directors each year. However, any director may request additional
executive sessions of non-management directors to discuss any matter of concern.
The Board of Directors has provided the means by which stockholders may send
communications to the Board or to individual members of the Board. Such
communications should be directed to the Secretary of the Company, 9189 Red
Branch Rd. Columbia, MD 21045, or by email at mail@gses.com, who will forward
them to the intended recipients.

     The Board of Directors reviews the independence of its members on an annual
basis. No directors will be deemed to be independent unless the Board
affirmatively determines that the director in question has no material
relationship with the Company, directly or as an officer, stockholder, member or
partner of an organization that has a material relationship with the Company.
The Board has not adopted any categorical standards of directors independence,
however, the Board of Directors employs the standards of independence of the
AMEX rules currently in effect. As a result of its Annual Review, the Board of
Directors has determined that Dr. Sheldon L. Glashow, Dr. Roger Hagengruber and
Joseph W. Lewis are independent. Based on these standards, all of the members of
the Audit Committee are independent.

     In 2004, the Board met one time and committees of the Board held a total of
five meetings. The average attendance at meetings of the board and committees
was 83%. During this period, all of the directors attended or participated in
more than 75% of the aggregate of the total number of meetings of the Board of
Directors and the total number of meetings held by all committees of the Board
of Directors on which each such director served, except for Mr. Lewis. The board
has established the following committees, the function and current members of
which are noted below:

     Executive Committee. The Executive Committee consists of George J. Pedersen
(Chairman) and Jerome I. Feldman. 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
did not meet formally during 2004.

     Audit Committee. The Audit Committee consists of Roger L. Hagengruber,
Sheldon L. Glashow and Joseph W. Lewis (Chairman). 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 four times during 2004.

     Nominating Committee. The Nominating Committee consists of Jerome I.
Feldman and George J. Pedersen. The Nominating Committee selects and recommends
nominees for election as directors. The Nominating Committee did not meet during
2004. Since the Company is a "controlled company" it is not required to have a
nominating committee comprised solely of independent directors or a majority of
independent directors.  The nominating committee or majority of the independent
directors, the Nominating Committee is not required to adopt a formal written
charter addressing the nomination process or a policy with regard to the
consideration of any director candidates recommended by security holders.

     Compensation Committee. The Compensation Committee consists of Jerome I.
Feldman and George J. Pedersen (Chairman). 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 once during 2004.
See "Report of the Compensation Committee", below. Since the Company is a
"controlled company" it is not required to have a compensation committee
comprised solely of independent directors.


Compensation of Directors

     In 2004, the Board restructured director compensation so only those
directors who were on the Audit Committee would receive compensation. All
members of the audit committee are independent directors who are neither
employees of the Company nor of GP Strategies. The 2004 director compensation
structure is as follows:


                         
                                                                     Estimated
                                   Annual                             Annual
  Title                            Retainer        Meetings         Compensation
--------------------------        -----------     -------------   -------------
Chairman, Audit Committee         $ 15,000         $ 8,000  (1)       $ 23,000

Audit Committeee Member           $ 10,000         $ 8,000  (1)       $ 18,000

     1 Includes $6,000 for estimated number of board meetings (4 times $1,500
each) and $2,000 for estimated number of Audit Committee meetings (4 times $500
each).

     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 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. There were no options granted to the
Directors in 2004.

     table, options with an average exercise price of $1.85 covering a total of 
     424,838 shares of common stock were granted to 42 other employees in the
     first quarter 2005.

     will benefit all shareholders commensurately. A 0% increase in stock price
     will result in $0 gain for the optionees. The potential realizable amounts
     shown illustrate the values that might be realized upon exercise
     immediately prior to 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 appreciation, if any, of the
     company's stock price.

Strategies executive with experience in the power industry and simulation
technology, as Chief Executive Officer. Mr. Moran continued as a GP Strategies
employee, however, Mr. Moran devoted 100% of his time to the performance of his
duties as CEO of GSE. Due to the related-party nature of this transaction, as GP
Strategies owned 58% of the outstanding common stock of the Company, the
Company's Audit Committee negotiated the compensation that the Company would pay
to GP Strategies for Mr. Moran's services, rather than the Compensation
Committee. After reviewing the nature of Mr. Moran's responsibilities as CEO of
the Company and the level of compensation of the other executives of GSE, the
Audit Committee approved a $35,000 charge by GP Strategies in 2003 for Mr.
Moran's compensation and benefits; and approved a charge of $300,000 by GP
Strategies in 2004 for Mr. Moran's compensation and benefits. As Mr. Moran
became an employee of th e Company on December 16, 2004, the actual charge from
GP Strategies for Mr. Moran's 2004 compensation was $289,000.

                      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 and George J. Pedersen.

Compensation Philosophy
 
     The compensation program for the executive officers of the Company is
developed and administered by the board and its Compensation Committee. 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

     Mr. Moran's compensation in 2004 was determined by the members of the Audit
Committee in connection with his election as the Company's Chief Executive
Officer in December 2003. The Audit Committee determined Mr. Moran's
compensation based on an analysis of competitive salaries for positions with
similar scope of responsibilities and job complexities for comparable companies.
The Audit Committee determined Mr. Moran's compensation instead of the
Compensation Committee since it was a related party transaction and the Audit
Committee is comprised solely of independent directors.

Implementation Guidelines

     To implement the general 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.

     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 2004 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.

     No bonuses were awarded in 2004 to the Company's principal executive
officer and the four other most highly compensated executive officers. However a
deferred bonus payment of $21,300 was made to Mr. Paris in 2004 as per the terms
of the change of control agreement related to the sale of the Company's Process
Automation business in September 2003.

     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.

     No options were granted to any of the named executive officers in 2004. In
general, the Compensation Committee's decisions concerning the specific
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 2004 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 of Directors, with the advice of the Compensation Committee, will
reexamine the Company's compensation philosophy and objectives periodically and
determine if changes should be considered.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
     
     The Compensation Committee is currently comprised of Mr. Pedersen, who is
the chairman of the Compensation Committee, and is chairman of the board, chief
executive officer and president of ManTech; and Mr. Feldman, who is chairman of
the board of the Company's board of directors, and is chairman of the board and
chief executive officer of GP Strategies.

     The Compensation Committee acts on matters related to other directors,
executive officers and related entity proposals. In accordance with applicable
law, any matter related to a member of the Compensation Committee requires
ratification by the independent directors or approval of the entire board.

Certain Relationships and Related Transactions

     GP Strategies beneficially owns approximately 59% of the Company. Jerome I.
Feldman, GSE's Chairman of the Board, is also the Chairman of GP Strategies'
Executive Committee of their Board of Directors and was GP Strategies' Chairman
of the Board and Chief Executive Officer until April 26 2005. Scott N.
Greenberg, a director of the Company, is also GP Strategies' Chief Executive
Officer and a member of their Board of Directors, and was their President and
Chief Financial Officer until May 2005. Douglas Sharp, the President of General
Physics, is a director of the Company, and Andrea D. Kantor, GP Strategies' Vice
President and General Counsel, is a director of the Company.

     In December 2003, GSE's Board of Directors elected John Moran, a GP
Strategies executive with experience in the power industry and simulation
technology, as Chief Executive Officer. Mr. Moran continued as a GP Strategies
employee, however, Mr. Moran devoted 100% of his time to the performance of his
duties as CEO of GSE. In 2003, GSE was charged $35,000 by GP Strategies for his
compensation and benefits; in 2004 GSE was charged $289,000 by GP Strategies for
Mr. Moran's compensation and benefits. On December 16, 2004, Mr. Moran became an
employee of GSE.

     On January 1, 2004, the Company entered into a Management Services
Agreement with GP Strategies Corporation in which GP Strategies agreed to
provide corporate support services to GSE, including accounting, finance, human
resources, legal, network support and tax. In addition, GSE uses the financial
system of General Physics, a subsidiary of GP Strategies. In 2004, GSE was
charged $685,000 for GP Strategies' services. The agreement has been extended
through December 31, 2005 without an increase in the fee. The agreement can be
renewed for successive one-year terms.

     In December 2003, GSE agreed to pay to General Physics, a fully-owned
subsidiary of GP Strategies, approximately $35,000 for services performed by
General Physics personnel in the fourth quarter 2003 for the implementation of
the Management Services Agreement. In addition, GSE was charged $30,000 by
General Physics for coverage under General Physics' directors and officers'
liability and umbrella insurance for November and December 2003.

     On September 29, 2003 the Company amended the ManTech Preferred Stock
issuance agreement to revise the conversion rate from $2.645 per share to
$1.5526 per share. The change in conversion rate increased the number of common
shares available upon conversion from 1,474,480 to 2,511,915. On October 23,
2003 ManTech elected to convert all of its preferred stock to common stock and
sold all of its GSE common stock and subordinated debt to GP Strategies. Due to
GP Strategies' acquisition of additional shares of the Company on that date,
bringing its ownership of the common stock of the Company from approximately 22%
to approximately 58%, the Company became a majority-owned subsidiary of GP
Strategies.

     In March 2003, GP Strategies extended its $1.8 million limited guarantee of
the Company's then credit facility and received 150,000 shares of the Company's
common stock with a value of $180,000 in consideration of such extension. On
March 30, 2004, the Company was added as an additional borrower under the
Financing and Security Agreement between General Physics and a financial
institution which expires on August 12, 2006. Under the terms of the agreement,
$1.5 million of General Physics' available credit facility has been carved out
for use by the Company. The line is collateralized by substantially all of the
Company's assets and provides for borrowings of up to 80% of eligible accounts
receivable and 80% of eligible unbilled receivables, up to a maximum of $1.5
million. GP Strategies also agreed to guarantee the Company's borrowings as part
of its fee pursuant to the Management Services Agreement described above.
     
     In 2004, Michael Feldman received a salary of $85,000 from the Company as
marketing manager of the Company and in 2003 received a salary of $16,000 from
the Company. Michael Feldman currently receives an annual salary of
approximately $110,000 from the Company as Managing Director, Marketing. Michael
Feldman is the son of Jerome I. Feldman, the Company's Chairman and the Chairman
of the Executive Committee of GP Strategies.

     On March 9, 2005, General Physics received a waiver to loan GSE ("GSE
Loan") up to a maximum of $1.0 million that will be due and payable by no later
than June 9, 2006 and will be on such other terms and conditions as are agreed
upon by General Physics and GSE. The GSE Loan would be reduced by any amounts
owed by GSE to GP Strategies and General Physics, primarily in connection with
the Management Services Agreement, which aggregated approximately $570,000 as of
March 31, 2005. Therefore, the availability under the GSE Loan would be
approximately $430,000.


           PROPOSAL 2: AMENDMENT TO THE 1995 LONG-TERM INCENTIVE PLAN


     The Board proposes that the stockholders of the Company approve an
amendment to the Long-Term Incentive Plan (As Amended and Restated Effective
June 25, 2001) (the "Plan"), which currently expires on June 30, 2005. The Board
has approved the amendment, subject to stockholder approval, which extends the
life of the plan three years to June 30, 2008. There are currently $2.5 million
shares reserved for issuance under the Plan, however, as of May 6, 2005 only 
145,344 shares are available for grant under the plan.  The Board is requesting
and recommends to the stockholders ratification and approval of the Plan
amendment to ensure that the Company maintains its ability to attract and
retain executive personnel, key employees, and directors, through the issuance
of option grants and to provide additional incentive by permitting certain key
individuals to participate in the ownership of the Company. The following is
information as of May 6, 2005 about shares of the Company's Common Stock that
may be issued upon the exercise of options under the Company's Long-Term
Incentive Plan (As Amended and Restated Effective June 25, 2001) (the "Plan").

   ------------------------------------------------------------------------------------------------------------

     Following is a summary of the material provisions of the Plan, which is
qualified in its entirety by the terms of the Plan that is published in this
Proxy as Appendix A. A copy of the Plan may also be obtained from the Plan
Administrator at the executive offices, 9189 Red Branch Road, Columbia,
Maryland, 21045.

     The purpose of the Plan is to promote the long-term growth and
profitability of the Company. The Plan is administered by the Board of
directors or a committee of the Board (the "Administrator"). The Plan permits
the granting of stock options to employees, directors or consultants (including
incentive stock options and nonqualified stock options) stock appreciation
rights, restricted or unrestricted stock awards, phantom stock, performance
awards or any combination of these.

     The Administrator has the powers vested in it by the terms of the Plan,
including determining the types of awards to be granted, number of shares
covered by each award, prescribed grant agreements evidencing such awards, and
the establishment of programs for granting awards. The Administrator has the
authority to administer and interpret the Plan and to adopt and interpret the
rules, regulations, agreements, guidelines and instruments as it determines are
necessary or advisable. In making such determination, consideration may be given
to the value of the services rendered by the respective individuals, their
present and potential contributions to the success of the Company and its
subsidiaries, and such other factors deemed relevant in accomplishing the
purposes of the Plan.

     If amended as per the proposal, the Plan will terminate on June 30, 2008.
All awards made under the Plan shall remain in effect until such awards have
been satisfied or terminated in accordance with the Plan and the terms of such
awards.

     At this time the only awards that have been made under the Plan are
nonqualified stock options. No tax consequences result from the grant of the
option. An option holder who exercises a nonqualified stock option generally
will realize compensation taxable as ordinary income in an amount equal to the
difference between the exercise price and the fair market value of the shares on
the date of exercise. The Company will be entitled to a deduction in the amount
of ordinary income so recognized.

     The rules governing the tax treatment of options and the receipt of shares
in connection with such grants are quite technical; accordingly, the above
description of tax consequences is necessarily general in nature and does not
purport to be complete. Moreover, statutory provisions are subject to change, as
their interpretation may vary in individual circumstances. Finally, the tax
consequences under applicable state law may not be the same as under the federal
income tax laws.

                    THE BOARD RECOMMENDS A VOTE FOR APPROVAL
                OF THE AMENDMENT TO THE LONG-TERM INCENTIVE PLAN
                (AS AMENDED AND RESTATED EFFECTIVE JUNE 25, 2001)





             PROPOSAL 3: APPROVAL OF INDEPENDENT PUBLIC ACCOUNTANTS
  
     Upon the recommendation of the Audit Committee, and subject to stockholder
approval, the Board has appointed the firm of KPMG LLP as independent public
accountants 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 public accountants on March 17,
2000, replacing PricewaterhouseCoopers.
   
     The following table presents fees for professional audit services rendered
by KPMG LLP for the audit of the Company's annual financial statements for 2004
and fees billed for other services rendered by KPMG LLP, together with a

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

        (1) Audit related fees consisted principally of fees for audits of 
        financial statements of certain employee benefit plans.

        (2) Tax fees consisted of fees for tax consultation and tax compliance
        services.


     A representative of KPMG LLP is expected to 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 public accountants
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.
The stockholder's ratification of the appointment of KPMG will not impact the
Audit Committee's responsibility pursuant to its charter to appoint, replace and
discharge the independent auditors. 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
       RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS INDEPENDENT PUBLIC
                                   ACCOUNTANTS


                         REPORT OF THE AUDIT COMMITTEE

     The Audit Committee of the GSE Systems, Inc. Board of Directors is
comprised of the three directors named below. Each member of the Audit Committee
is an independent director as defined by applicable Securities and Exchange
Commission (SEC) rules and American Stock Exchange (AMEX) listing standards. In
addition, the Board of Directors has determined that Joseph W. Lewis is an
"audit committee financial expert" as defined by applicable SEC rules and
satisfies the "accounting or related financial management expertise" criteria
established by AMEX. The Audit Committee operates under a written charter
adopted by the Board of Directors.

     Management is responsible for the Company's internal controls and preparing
the Company's consolidated financial statements. The Company's independent
accountants are responsible for performing an independent audit of the
consolidated financial statements in accordance with generally accepted auditing
standards and issuing a report thereon. The Committee is responsible for
overseeing the conduct of these activities and appointing the Company's
independent accountants.

     The Audit Committee reviewed and discussed the Company's consolidated
financial statements for the year ended December 31, 2004 with management and
the Company's independent accountants. Management represented to the Audit
Committee that the Company's consolidated financials statements were prepared in
accordance with generally accepted accounting principles. The Audit Committee
discussed with the independent auditors the matters required to be discussed by
the Statement of Auditing Standards No. 61, Communication with Audit Committees,
relating to the conduct of the audit. The Audit Committee has received the
written disclosures and the letter from KPMG required by Independence Standards
Board Standard No. 1, Independence Discussions with Audit Committees, and has
discussed with KPMG their independence and satisfied itself as to the auditor's
independence.

     Based on the Audit Committee's discussions with management and the
independent accountants and the Audit Committee's review of the representations
of management and the report of the independent accountants, the Audit Committee
recommended to the Board of Directors that the audited financial statements for
the fiscal year ended December 31, 2004 be included in the Company's Annual
Report on Form 10-K for the fiscal year ended December 31, 2004 for filing with
the SEC. In addition, the Audit Committee approved KPMG as the independent
auditors for the Company for the fiscal year 2005.

     Notwithstanding anything to the contrary set forth in any of the Company's
previous filings under the Securities Act of 1933 (the "Securities Act") or the
Securities Exchange Act of 1934 (the "Exchange Act") that might incorporate
future filings made by the Company under those statutes, in whole or in part,
this report shall not be deemed to be incorporated by reference into any such
filings, nor will this report be incorporated by reference into any future
filings made by the Company under those statutes.

                           Joseph W. Lewis, Chairman
                             Dr. Sheldon L Glashow
                            Dr. Roger L. Hagengruber

Policy on Pre-Approval of Services Provided by the Independent Auditors

     Pursuant to the requirements of the Sarbanes-Oxley Act of 2002, the terms
of the engagement of KPMG are subject to specific pre-approval policies of the
Audit Committee. All audit and permitted non-audit services to be performed by
KPMG require pre-approval of the Audit Committee or the Chairman of the Audit
Committee. The procedures require all proposed engagements of KPMG for services
of any kind be directed to the Company's Chief Financial Officer and then
submitted for approval to the Audit Committee prior to the beginning of any
service.

            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 more than
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. These Reporting Persons are required by SEC regulations to provide the
Company with copies of all Section 16(a) filings. Based solely on a review of
the copies of such forms furnished to the Company, or written representations
from certain Reporting Persons that such filings were not required, the Company
believes that during 2004 the Reporting Persons complied with all Section 16(a)
reporting requirements applicable to them.

                      CODE OF BUSINESS CONDUCT AND ETHICS

     The Company has adopted a Code of Ethics for Senior Financial Officers of
the Company and its subsidiaries and a Conduct of Business Policy for directors,
officers and employees of the Company and its subsidiaries. It is the Company's
intention to disclose any waivers of such Code or Ethics or Conduct of Business
Policy on the Company's website at www.gses.com. The Company will provide a copy
of such Code of Ethics and Conduct of Business Policy to any person upon written
request made to the Company's Secretary in writing to the following address: GSE
