the following purposes:

(1)  To  elect  two  directors,  each for a term of  three  years  or until  his

(3)  To ratify the appointment of PricewaterhouseCoopers L.L.P. as the Company's

(4)  To transact such other  business as may properly come before the meeting or

     This proxy statement and the  accompanying  form of proxy and the Company's
1998  Annual  Report to  Stockholders  are first being  released  for mailing to
stockholders on or about May 6, 1999.

     We urge you to date, sign and mail your proxy promptly to make certain that
your shares will be voted at the Annual  Meeting.  Proxies in the enclosed  form
that are received in time for the Annual Meeting will be voted at the meeting in
accordance  with the  instructions,  if any,  indicated on the proxy card. If no
instruction  is given,  the  proxy  will be voted in favor of the  nominees  for
election as directors  specified under  "Election of Directors;  and in favor of
approving an amendment to the Company's  1995 Long-Term  Incentive  Plan; and in
favor of ratification of the appointment of PricewaterhouseCoopers L.L.P. as the

any other matters properly come before the Annual 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.  Any proxy may be revoked at any
time before it is  exercised  by giving  written  notice of such  revocation  or
delivering a later dated proxy to the  Corporate  Secretary of the Company prior
to the meeting, or by the vote of the stockholder in person at the meeting.  The
presence of a stockholder  at the Annual Meeting will not  automatically  revoke
that stockholder's proxy.



                  VOTING SECURITIES AND PRINCIPAL STOCKHOLDERS

Voting Securities

     Only  stockholders of record at the close of business on April 7, 1999 will
be entitled to vote at the Annual Meeting and any  adjournments or postponements
thereof.  On April 7, 1999,  there were 5,065,688  outstanding  shares of Common
Stock.  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.  Assuming the presence
of a quorum, the affirmative vote of a plurality of the votes cast by holders of
shares of Common Stock is required for the election of directors.

     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.

     For purposes of the election of directors,  a withheld vote will not affect
the plurality vote required for the election of directors.  All other matters to
come before the Annual Meeting  require the approval of a majority of the shares
of Common  Stock  present,  in person or by proxy,  at the  Annual  Meeting  and
entitled  to vote.  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 (arising from a lack
of instructions from beneficial  owners),  although present for quorum purposes,
will be deemed  shares not present to vote on such matters,  and therefore  will
not count as votes for or against  the  proposals,  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 certain  information  known to the Company
with respect to beneficial  ownership of the Company's Common Stock, as of April
7,  1999,  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 filed
by ManTech International Corporation ("ManTech"), GP Strategies Corporation ("GP
Strategies") and 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.




                                                                              Number of               Percent of

                        PROPOSAL 1: ELECTION OF DIRECTORS

     The Bylaws of the Company provide that the number of directors constituting
the Board shall be as determined  from time to time by the Board.  The Board has
acted to fix the number of directors at seven.

     Pursuant to the terms of the Company's Amended and Restated  Certificate of
Incorporation,  the Board is divided  into  three  classes,  as nearly  equal in
number as reasonably possible, with terms expiring at the Annual Meeting ("Class
I"),  the Annual  Meeting of  Stockholders  in 2000  ("Class II") and the Annual
Meeting of Stockholders in 2001 ("Class III"), respectively.



     At  the  Annual  Meeting,  two  directors  are to be  elected  as  Class  I
directors,  each for a term of three  years,  or until  his  successor  has been
elected and qualified. The Board has nominated for election as Class I directors
Christopher M. Carnavos and Sheldon L. Glashow,  both of whom currently serve on
the  Board as Class I  directors.  Further,  the  Board  has  directed  Scott N.

remainder of his  respective  three-year  term,  or until his successor has been
elected and qualified.  Messrs. Carnavos, Glashow, and Greenberg are hereinafter
collectively referred to as the "Director Nominees."

     The proxies solicited hereby, unless directed to the contrary therein, will
be voted for election of the  Director  Nominees.  All of the Director  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 Director Nominees will not be
a candidate or will be unable to serve, but if either occurs it is intended that
the shares represented by proxies will be voted for such substituted  nominee or
nominees as the Board, in its discretion, may designate.

     The  following  sets  forth  certain  biographical   information,   present

the Board on which the director served. Martin Pollak, a Director of the Company
during 1998,  resigned as a Director in March 1999.  The vacancy  created by Mr.
Pollak's resignation was filled by the Board's appointment of Mr. Greenberg as a
Class II director.


     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),  Jerome I.  Feldman  and  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 one (1) time during 1998.

     Audit  Committee.  The Audit  Committee  consists of Sheldon L. Glashow and
Sylvan  Schefler.  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 did not meet
during 1998.

     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 to the Board.  The  Nominating  Committee did
not meet during 1998.

     The Nominating Committee will consider  recommendations by stockholders for
nominees for election as directors.  Nominations of individuals  for election to
the  Board  must be made in  accordance  with the  procedures  set  forth in the
Company's Bylaws. In general,  such procedures require stockholders to provide a
written notice (a "Nomination  Notice") which sets forth,  as to each individual
nominated,   information   regarding  the  nominee's   background  and  business
experience (including other directorships held) and the nominee's involvement in
certain  legal  proceedings.  With  respect to the  stockholder  submitting  the
Nomination  Notice  and any  person  acting in  concert  with such  stockholder,
information must be furnished regarding such person's name and business address,
the names and  addresses of such persons as they appear on the  Company's  books
and the class and number of shares of Company stock  beneficially  owned by such
persons.  A written consent to be named in a proxy statement as a nominee and to
serve as a director  if  elected,  signed by the  nominee,  also is  required to
accompany any Nomination Notice. Nomination Notices are required to be delivered
to the Corporate  Secretary of the Company not less than 60 and not more than 90
days prior to the date of the Annual Meeting to be held in 2000.

     Compensation  Committee.  The Compensation  Committee consists of Jerome I.
Feldman,  George J.  Pedersen and  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 (5)
times during 1998. See "Report of the Compensation Committee", below.

     Year 2000  Committee.  The Year 2000  Committee  consists of John A. Moore,
Jr., and Sylvan  Schefler.  The Year 2000 Committee is responsible for oversight
of management's implementation of the Company's Year 2000 Readiness program. The
Year 2000 Committee was created during 1998.

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 or Committee meeting attended.

     Each person who becomes a  Non-Management  Director will receive an initial
grant of options under the Plan to purchase  1,500 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.  In
addition,  under the Plan, each Non-Management Director serving as a director on
December 31 of each calendar year  (commencing in 1995)  automatically  receives
options to purchase 1,500 shares of Common Stock (or if such director has served
for less than a full year, a prorated  portion  thereof) with an exercise  price
per share  equal to the fair  market  value of a share of  Common  Stock on such
date.  All 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.  As of December 31,  1998,  Messrs.  Glashow,  Schefler,
Feldman, Pedersen, Pollak and Moore served as Non-Management Directors.

     In February  1997,  Messrs.  Feldman,  Pedersen  and Pollak  each  received
options under the Plan to purchase 1,500 shares of Common Stock with an exercise
price of $9.25 per share upon being classified as Non-Management Directors. Upon
becoming a  Non-Management  Director in November  1997,  Mr.  Moore  received an
option  under the Plan to purchase  1,500  shares of Common Stock at an exercise
price of $6.25 per share.  Each person who was a  Non-Management  Director as of
December  1, 1997  participated  in a  surrender/replacement  of stock  options,
pursuant  to which  previously  granted  options  to  purchase a total of 16,887
shares of Common  Stock at various  prices were  surrendered  by  Non-Management
Directors and replaced with options to purchase 16,887 shares of Common Stock at
$3.875  per  share.  In May  1998,  the  Company  and  the  Board  of  Directors
unanimously  approved the immediate vesting of all such replacement  options for
Non-Management  Directors.  On December 31,  1998,  Messrs.  Glashow,  Schefler,
Feldman,  Moore,  Pedersen and Pollak each  received  options  under the Plan to
purchase 1,500 shares of Common Stock with an exercise price of $2.50 per share.

     In April 1998, the Company awarded Messrs.  Feldman and Pedersen options to
acquire  12,500  shares of Common  Stock each at an exercise  price of $2.75 per
share.

     Additionally, since May 1997, each of Messrs. Feldman and Pedersen has been
compensated  $5,000  per month for his  services  as  Chairman  of the Board and
Chairman of the Executive Committee, respectively.

1 The options become  exercisable in three  installments with 40% vesting on the
first  anniversary  of the date of grant and 30%  vesting  on each of second and
third anniversaries of the date of grant,  subject to acceleration under certain
circumstances.

2 In addition to the option  grants to the  executive  officers  reported in the
table,  options  with an  average  exercise  price of $2.89  covering a total of
87,200 shares of Common Stock were granted to 38 other employees during 1998.

3 No gain to  optionees is possible  without an increase in stock  price,  which
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.

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 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
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. Carnavos serves as the principal  executive  officer within the Company
and in this  role has  directed  and  overseen  the  return  of the  Company  to
operating  profitability,  including  revenue growth of 14% for both the Process
and Power core units  combined.  Promoted  to  President  in January  1998,  Mr.
Carnavos  initiated and directed the restructure and divestiture of Erudite at a
better than expected price. In recognition of this  accomplishment he received a
$25,000  bonus  in May  1998.  Recognizing  all of his  accomplishments  and his
promotion to President, the Board approved in July 1998 a $15,000 (7%) raise for
Mr. Carnavos.



     Implementation Guidelines

     To implement the  compensation  philosophy  described  above, the Company's
executive compensation program has three primary components:  (i) a base salary,
(ii) incentive 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 be established  primarily 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.

     Incentive Bonus Awards.  The incentive bonus award is intended to focus the
efforts of the executives  and other  employees on the attainment of performance
objectives  as  recommended  by the  Compensation  Committee and approved by the
Board.  The  Board,  with the  advice  and  recommendation  of the  Compensation
Committee,  will establish overall  performance  goals for the Company.  If such
performance  goals are achieved,  it is expected that a pool of bonus funds will
be available for incentive  bonus  awards.  The size of the pool will  generally
depend on the success in meeting such objectives.

     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, determine the pool of bonus funds available for incentive bonus awards
and make such awards to the  Company's  executive  officers.  Management  of the
Company will be  responsible  for awarding  the  remaining  bonus funds to other
officers  and  employees  of  the  Company,  taking  into  account  the  general
compensation  philosophy of the Company and the performance goals established by
the Board.

     For more  information  regarding the bonuses awarded in 1996, 1997 and 1998
to the  Company's  principal  executive  officers and the four other most highly
compensated  executive officers of the Company,  see "Executive  Compensation --
Summary of Cash and Certain Other Compensation".

     Long-Term Incentive Award. The third element of the Company's  compensation
program will be provided  through the Company's  Long-Term  Incentive  Plan (the
"Plan"),  which is also  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 (the
"Code"),  and may grant  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 absolute  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,
incentive 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 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.

           COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee of the Company is 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;  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;  and Mr. Carnavos,  who is President of the
Company.

     The  Company's  performance  on certain  customer  contracts  is secured by
performance  guarantees  and furnished by its  subsidiaries'  respective  former
parent organizations  amounting to $258,000 as of December 31, 1998. The Company
has agreed to  indemnify  those  parties for any  payments  required  under such
guarantees.

     One of the  Company's  subsidiaries  subleased  office  space to ManTech at
market price based on square  footage used. For 1998,  such charges  amounted to
$29,828. The sublease arrangement expired during 1998.

     In 1997,  a  subsidiary  of the Company  entered  into  certain  agreements
regarding  the  formation  of a joint  venture  with a company  organized in the
People's  Republic of China.  In connection with the initial  capitalization  of
this joint venture,  each of ManTech and GP Strategies made advances of $126,000
on behalf of the  Company.  These  advances  were made in  exchange  for  future
considerations,  including the option for direct investment in the joint venture
by ManTech and/or GP Strategies  subject to necessary  approvals and consents in
the People's  Republic of China.  In 1998,  the Company  determined  that it was
advisable to discontinue  its  participation  in this joint venture  partner and
with ManTech whereby the joint venture was converted into a wholly-owned foreign
entity,  the  entire  equity  of  which  was then  transferred  to  ManTech.  In
connection   with  this  equity   transfer,   ManTech  assumed  the  outstanding
contractual  obligations of the entity and certain other  responsibilities.  The
cash  consideration  from  ManTech to the  Company for the equity  transfer  was
nominal.

     The Company has received a commitment  letter from a financial  institution
for a new credit  facility  with a maturity  date of March 31,  2000,  which the
Company expects to finalize by mid-May 1999. The terms and conditions of the new
facility,  which would  provide  for a $6 million  Power  Systems  line and a $3
million  Process  Solutions  line,  are  substantially  the same as the existing
facility,  including the  requirement  for the EXIM guarantee and the guarantees
described below.

     In connection  with the existing lines of credit and the new facility,  the
Company has arranged for certain  guarantees to be provided on its behalf to the
bank by GP Strategies  and ManTech.  In  consideration  for the  above-mentioned
guaranties,  the Company has granted each of ManTech and GP Strategies  warrants
to purchase shares of the Company's Common Stock; each of such warrants provides
the right to purchase at least 150,000  shares of the Company's  Common Stock at
$2.375 per share.  The Company has  recognized  $300,000 as the  estimated  fair
value of such warrants in the consolidated  financial  statements.  During 1998,
the  Company  recognized  $180,000  of expense  related to these  warrants.  The
Company  will  expense  the  remainder  of the fair  value  over the term of the
guarantees.  The fair value of the  warrants  was  determined  using the Black -
Scholes  valuation  model.  Assumptions used in the calculation were as follows:
dividend yield of 0%, expected  volatility of 61%,  risk-free  interest rates of
5.6% and expected terms of 2.5 years.

     Although the Company intends to replace its expiring credit facilities,  as
described  above,  there  can  be no  assurance  that  such  financing  will  be
completed.  In the event  that the  Company  is  unsuccessful  in  extending  or
obtaining  new lines of credit,  GP  Strategies  and ManTech each have agreed to
provide  working  capital  support of up to $1.8  million  ($3.6  million in the
aggregate) to the Company.


   PROPOSAL 2: AMENDMENT AND RESTATEMENT OF THE 1995 LONG TERM INCENTIVE PLAN

     The  Board  proposes  that  the  stockholders  of the  Company  approve  an
amendment and restatement of the GSE Systems, Inc. 1995 Long-Term Incentive Plan
(As Amended and Restated  Effective  November 20, 1998) (the "Prior Plan").  The
Board approved the amendment and restatement of the Prior Plan,  effective April
5, 1999,  subject to the approval of the  stockholders  within 12 months of such
effective  date (the "Plan").  The Plan will not adversely  affect the rights or
obligations  under any award  granted  under the Prior  Plan of any  grantee  or
holder of such award without that person's approval.

     The  following is a fair and complete  summary of the Plan; it is qualified
in its  entirety by  reference  to the full text of the Plan,  which  appears as
Exhibit A to this Proxy Statement.

General

     Purpose:  The  purpose of the Plan is to promote the  long-term  growth and
profitability  of the Company by providing key people with incentives to improve
stockholder  value and  contribute  to the growth and  financial  success of the
Company,  and by  enabling  the  Company  to  attract,  retain  and  reward  the
best available persons for positions of substantial responsibility.

     Shares  Available under the Plan: The number of shares of Common Stock that
may be issued with respect to awards  granted  under the Plan and the Prior Plan
shall not exceed an  aggregate of 1,175,000  shares of Common  Stock.  The Prior
Plan  provided  that the  maximum  number of shares of Common  Stock that may be
issued thereunder was 625,000.

     Under the Plan,  the maximum  number of shares of Common  Stock  subject to
awards of any combination  that may be granted during any one fiscal year of the
Company  to any one  individual  shall be  limited  to  400,000.  The Prior Plan
provided that the maximum number of shares of Common Stock with respect to which
an employee may receive awards was 100,000.

     The above  limits under the Plan are subject to  adjustment  to reflect any
stock dividends, split-ups, recapitalizations, mergers, consolidations, business
combinations or exchanges of shares and the like. If any award, or portion of an
award,  granted  under  the  Plan  or  the  Prior  Plan  expires  or  terminates
unexercised,  becomes  unexercisable  or is forfeited  or otherwise  terminated,
surrendered  or canceled as to any shares,  or if any shares of Common Stock are
surrendered  to the Company in  connection  with any award  (whether or not such
surrendered  shares were acquired pursuant to any award),  the shares subject to
such award and the surrendered  shares shall thereafter be available for further
awards under the Plan. As of April 5, 1999,  the fair market value of a share of
the Company's Common Stock, determined by the last reported sale price per share
of  Common  Stock on such date as quoted on the  American  Stock  Exchange,  was
$4.125.

     Administration:  The  Plan  will be  administered  by the  Board or by such
committee or  committees as may be appointed by the Board from time to time (the
Board,  committee or committees hereinafter referred to as the "Administrator").
The Prior  Plan  required  that the  administration  thereof be  performed  by a
committee of  non-employee  directors.  The Plan neither  requires nor prohibits
compliance with those standards.

     The  Administrator  shall have full power and authority to take all actions
necessary  to carry out the purpose and intent of the Plan,  including,  but not
limited to, the authority to:  (i) determine  the eligible  persons to whom, and
the time or times at which awards shall be granted;  (ii) determine the types of
awards to be granted;  (iii) determine  the number of shares to be covered by or
used for reference purposes for each award; (iv) impose such terms, limitations,
restrictions and conditions upon any such award as the Administrator  shall deem
appropriate;  (v) modify,  amend,  extend or renew outstanding awards, or accept
the surrender of outstanding awards and substitute new awards (provided however,
that,  except as noted below, any modification  that would materially  adversely
affect  any  outstanding  award  shall not be made  without  the  consent of the
holder);  (vi) accelerate  or otherwise change the time in which an award may be
exercised or becomes  payable and to waive or accelerate the lapse,  in whole or
in part, of any restriction or condition with respect to such award,  including,
but not limited to, any  restriction or condition with respect to the vesting or
exercisability  of an award following  termination of any grantee's  employment;
and (vii) establish  objectives and  conditions,  if any, for earning awards and
determining whether awards will be paid after the end of a performance period.

     In the event of changes in the Common Stock of the Company by reason of any
stock dividend,  split-up,  recapitalization,  merger,  consolidation,  business
combination or exchange of shares and the like, the Administrator  shall, in its
discretion,  make  appropriate  adjustments  to the  maximum  number and kind of
shares  reserved  for  issuance or with  respect to which  awards may be granted
under  the  Plan  and to the  number,  kind  and  price  of  shares  covered  by
outstanding  awards,  and shall,  in its  discretion  and without the consent of
holders of awards, make any other adjustments in outstanding  awards,  including
but not limited to reducing the number of shares  subject to awards or providing
or mandating alternative  settlement methods such as settlement of the awards in
cash or in shares of Common Stock or other  securities  of the Company or of any
other  entity,   or  in  any  other  matters  which  relate  to  awards  as  the
Administrator  shall,  in its sole  discretion,  determine  to be  necessary  or
appropriate.

     Without the consent of holders of awards,  the  Administrator,  in its sole
discretion,  may make any modifications to any awards, including but not limited
to  cancellation,  forfeiture,  surrender or other  termination of the awards in
whole or in part  regardless  of the  vested  status of the  award,  in order to
facilitate  any business  combination  that is authorized by the Board to comply
with  requirements  for  treatment  as a pooling of  interests  transaction  for
accounting purposes under generally accepted accounting principles.

     Without  the  consent  of  holders  of  awards,  the  Administrator  in its
discretion is authorized to make adjustments in the terms and conditions of, and
the  criteria  included in,  awards in  recognition  of unusual or  nonrecurring
events affecting the Company, or the financial  statements of the Company or any
subsidiary,  or of  changes  in  applicable  laws,  regulations,  or  accounting
principles,  whenever the  Administrator  determines  that such  adjustments are
appropriate  in order to prevent  dilution  or  enlargement  of the  benefits or
potential benefits intended to be made available under the Plan.

     Participation:  Participation  in the Plan  will be open to all  employees,
officers,  directors and consultants of the Company or any of its affiliates, as
may be selected by the  Administrator  from time to time.  As of March 31, 1999,
two  non-employee  directors,  and  approximately  380 employees and consultants
would be eligible  to  participate  in the Plan.  The Prior Plan  provided  that
options,  stock  appreciation  rights and restricted and incentive  stock awards
thereunder  could  be  granted  or  awarded  only to  employees,  provided  that
directors of the Company who were not employees could receive nonstatutory stock
options in accordance with the Independent  Director  Program as provided in the
Prior Plan. See "Type of Awards - Elimination of Independent Director Program."

Type of Awards

     The Plan would  allow  stock  options,  stock  appreciation  rights,  stock
awards,  phantom stock awards and performance awards to be granted. These awards
may be granted separately or in tandem with other awards. The Administrator will
determine the prices,  expiration dates and other material conditions upon which
such awards may be exercised.  The Company may make or guarantee  loans to award
recipients to assist them in exercising  awards and satisfying  any  withholding
tax obligations.

     The Prior Plan permitted grants of options,  stock appreciation  rights and
restricted and incentive  stock awards.  The Prior Plan did not permit grants of
phantom stock awards or performance-based  awards other than stock awards. Under
the Prior Plan, a stock appreciation right could be granted independent of or in
connection with an option, but not in tandem with any other award.

     Stock Options:  The Plan allows the Administrator to grant either awards of
incentive  stock  options as that term is defined in section 422 of the Internal
Revenue Code of 1986,  as amended (the "Code") or  nonqualified  stock  options;
provided,  however,  that awards of incentive  stock options shall be limited to
employees of the Company or of any subsidiary of the Company.  Options  intended
to qualify as  incentive  stock  options  under  Code  section  422 must have an
exercise  price at least  equal to fair market  value on the date of grant,  but
nonqualified  stock options may be granted with an exercise price less than fair
market value. The option exercise price may be paid in cash, by tender of shares
of Common Stock, by a combination of cash and shares,  or by any other means the
Administrator  approves. The Prior Plan prohibited options exercisable more than
ten years after the date of grant. The Plan does not contain this prohibition.

     Stock  Appreciation  Rights:  The Plan  allows the  Administrator  to grant
awards of Stock  Appreciation  Rights  ("SAR").  An SAR  entitles  the holder to
receive a payment in cash,  in shares of Common Stock,  or in a  combination  of
both,  having an  aggregate  value  equal to the  product  of (i) the  excess of
(A) the fair market value on the exercise date of one share of Common Stock over
(B) the base price per share  specified in the grant  agreement,  times (ii) the
number of shares specified by the SAR, or portion  thereof,  which is exercised.
The Prior Plan prohibited stock  appreciation  rights  exercisable more than ten
years after the date of grant. The Plan does not contain this prohibition.

     Stock and Phantom Stock Awards:  The Plan allows the Administrator to grant
restricted   or   unrestricted   stock   awards,   or  awards   denominated   in
stock-equivalent  units  ("phantom  stock")  to  eligible  participants  with or
without payment of consideration by the grantee.  Stock awards and phantom stock
awards may be paid in cash,  in shares of Common Stock,  or in a combination  of
both.

     Performance  Awards: The Plan allows the Administrator to grant performance
awards  which  become  payable  in cash,  in  shares of  Common  Stock,  or in a
combination of both, on account of attainment of one or more  performance  goals
established  by  the   Administrator.   Performance  goals  established  by  the
Administrator  may be based on the Company's or an affiliate's  operating income
or one or more other business criteria selected by the Administrator  that apply
to an individual or group of individuals,  a business unit, or the Company or an
affiliate as a whole,  over such  performance  period as the  Administrator  may
designate.

     Elimination of Independent  Director Program: The Plan does not contain the
Independent   Director  Program  that  was  provided  in  the  Prior  Plan.  The
Independent  Director Program provided that each director of the Company who was
not a Company  employee was entitled to a  nonqualified  stock option granted on
the date that person became a non-employee  director and, effective December 31,
1995,  on each  following  December  31st.  Each option  permits the director to
purchase  1,500  shares of the Common  Stock,  except  that,  with respect to an
option  granted on December 31st of the  director's  first year of service,  the
number of shares subject to the option was adjusted pro rata based on the number
of days of service as  director.  The  options  under the  Independent  Director
Program vest at a rate of 40% on the first anniversary of the grant date and 30%
on each of the next two  anniversaries.  Each option has an exercise price equal
to the fair market value of the grant date. The options terminate on the earlier
of the  seventh  anniversary  of the  grant  date,  fifth  anniversary  after  a
termination  of service by reason of  retirement,  disability,  death or removal
without cause, or the 90th day after any other termination of service. Under the
Plan,  any  awards  for  directors  will  be  granted  at  the   Administrator's
discretion.

Awards Under the Plan

     Because  participation  and the types of awards  granted under the Plan are
subject to the  discretion  of the  Administrator,  the benefits or amounts that
will be received by any  participant  or groups of  participants  if the Plan is
approved  are  not  currently   determinable.  



The following table provides information regarding awards granted under the Plan

- -------------  
1 The  value of each  award is the  product  of (i) the  excess  of (A) the fair
market value of a share of Common Stock as December 31, 1998, $2.50  (determined
by the last reported sale price per share of Common Stock on such date as quoted
on the Nasdaq National Market System), over (B) the exercise price of the award,
and (ii) the number of shares (vested and nonvested) subject to the award.

     Messrs. Carnavos,  Feldman,  Pedersen, Jen, Southern,  Moore, Greenberg and
Hough received options under the Plan, subject to the stockholders'  approval of
the Plan. Messrs. Carnavos,  Feldman and Pedersen have options to purchase up to
100,000 shares of Common Stock.  Messrs.  Jen,  Southern,  Moore,  Greenberg and
Hough have options to purchase up to 50,000 shares of Common Stock. In the first
four years of the option,  the option will become vested and  exercisable  as to
35% of the  shares  subject  thereto if the fair  market  value per share of the
Common Stock is at least $8 for any 15 out of any 30  consecutive  trading days,
and as to 100% of the shares if fair market  value per share of the Common Stock
is at least $10 for any 15 out of any 30  consecutive  trading days.  The option
will also become  vested and  exercisable  as to 100% of the shares on the fifth
anniversary  of the grant  date.  In order for  vesting  to occur in each of the
circumstances  discussed above, the individual must be continuously  employed by
the Company from the grant date through the vesting date.  Upon an  individual's
termination of employment with the Company,  the unvested  portion of his option
will terminate  immediately  and the vested portion will terminate 90 days after
the termination of employment.  The  Administrator may modify the options in any
manner if the options result or can result in any adverse  accounting  treatment
for the  Company,  including  a  compensation  expense  chargeable  against  the
Company's income statement.

Amendment and Termination

     The Board may terminate, amend or modify the Plan or any portion thereof at
any time.

Federal Income Tax Consequences

     The  following  is a general  summary  of the  current  federal  income tax
treatment of stock  options,  which would be  authorized to be granted under the
Plan, based upon the current provisions of the Code and regulations  promulgated
thereunder.

     Incentive  Stock  Options:  Incentive  stock  options  under  the  Plan are
intended to meet the  requirements  of Code  section  422.  No tax  consequences
result from the grant of the option. If an option holder acquires stock upon the
exercise,  no income will be recognized by the option holder for ordinary income
tax purposes  (although the difference between the option exercise price and the
fair market value of the stock  subject to the option may result in  alternative
minimum tax  liability to the option  holder) and the Company will be allowed no
deduction as a result of such exercise,  provided that the following  conditions
are met:  (a) at  all times  during the  period  beginning  with the date of the
granting  of the option and  ending on the day three  months  before the date of
such  exercise,  the  option  holder  is an  employee  of  the  Company  or of a
subsidiary;  and (b) the  option holder makes no disposition of the stock within
two years  from the date the  option is  granted  nor  within one year after the
stock is transferred to the option holder. The three-month period is extended to
one year in the event of  disability  and is waived in the event of death of the
employee.  In the  event of a sale of such  stock  by the  option  holder  after
compliance with these conditions,  any gain realized over the price paid for the
stock  ordinarily  will be treated as capital gain, and any loss will be treated
as capital loss, in the year of the sale.

     If the  option  holder  fails to  comply  with the  employment  requirement
discussed  above,  the tax  consequences  will be the same as for a nonqualified
option,  discussed  below. If the option holder fails to comply with the holding
period  requirements  discussed above, the option holder will recognize ordinary
income in an amount  equal to the  lesser of (i) the  excess of the fair  market
value of the stock on the date the option was exercised  over the exercise price
or  (ii) the  excess  of the  amount  realized  upon such  disposition  over the
exercise price.  Any additional gain ordinarily will be recognized by the option
holder as capital gain, either long-term or short-term, depending on the holding
period of the  shares.  If the  option  holder  is  treated  as having  received
ordinary  income  because of his or her failure to comply with either  condition
above, an equivalent deduction will be allowed to the Company in the same year.

     Nonqualified  Stock Options:  No tax consequences  result from the grant of
the option. An option holder who exercises a nonqualified stock option with cash
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,  and the  Company  will be  entitled  to a
deduction  from  income  in the same  amount  in the  fiscal  year in which  the
exercise  occurred.  The option  holder's  basis in such shares will be the fair
market value on the date income is realized, and when the holder disposes of the
shares  he or she will  recognize  capital  gain or loss,  either  long-term  or
short-term, depending on the holding period of the shares.

     Disallowance of Deductions: The Code disallows deductions for publicly held
corporations  with respect to  compensation  in excess of $1,000,000 paid to the
corporation's chief executive officer and its four other most highly compensated
officers.  However,  compensation payable solely on account of attainment of one
or more  performance  goals is not subject to this  deduction  limitation if the
performance   goals  are   objective,   pre-established   and  determined  by  a
compensation  committee  comprised solely of two or more outside directors,  the
material terms under which the  compensation  is to be paid are disclosed to the
stockholders  and approved by a majority  vote, and the  compensation  committee
certifies  that the  performance  goals and other  material  terms  were in fact
satisfied before the  compensation is paid. Under this exception,  the deduction
limitation does not apply with respect to compensation  otherwise  deductible on
account of stock options and stock  appreciation  rights  granted at fair market
value  under a plan which  limits the number of shares that may be issued to any
individual and which is approved by the corporation's stockholders.

     The  affirmative  vote of holders of the majority of shares of Common Stock
which are  present at the Annual  Meeting in person or by proxy and  entitled to
vote are  required  to  approve  the Plan.  Any  shares  not voted  (whether  by
abstention,  broker non-vote,  or otherwise) have the effect of a negative vote.
The Board unanimously  recommends that the stockholders vote for approval of the
Plan.


              PROPOSAL 3: INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

     The Board, upon the  recommendation  of the Audit Committee,  has appointed
the firm of PricewaterhouseCoopers L.L.P. as independent auditors of the Company
for the current fiscal year. This  internationally  known firm has served as the
Company's  independent  auditors  since  1994  and  has no  direct  or  indirect
financial  interest in the Company.  Although not legally required to do so, the
Board  is  submitting  the  selection  of   PricewaterhouseCoopers   L.L.P.  for
ratification by the stockholders at the Annual Meeting.

     A representative  of  PricewaterhouseCoopers  L.L.P. will be present at the
Annual  Meeting and will have the  opportunity to make a statement if he desires
to do so.  It is  anticipated  that such  representative  will be  available  to
respond to appropriate questions from stockholders.


             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 1998,  the  Reporting  Persons  complied with all Sections
16(a) reporting  requirements  applicable to them except that one (1) report was
inadvertently filed late on behalf of Mr. Southern.


                                 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, 1998 is enclosed  (without  exhibits)  with this
proxy  statement;   also  enclosed  is  the  Company's  1998  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 2000 must
do so no later than December 31, 1999.

     In  addition,  in  accordance  with the  Company's  Bylaws,  in order for a
stockholder  proposal to be properly  brought before the 2000 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
2000.

                                              By Order of the Board of Directors

                          1995 LONG-TERM INCENTIVE PLAN
                (As Amended and Restated Effective April 5, 1999)

1.   Restatement, Purpose and Types of Awards

     GSE Systems,  Inc., a Delaware corporation (the "Corporation"),  maintained
the GSE Systems, Inc. 1995 Long-Term Incentive Plan (As Amended through November
20, 1998) (the "Prior Plan").  The Prior Plan has been amended and restated,  as
set forth  herein,  effective  April 5,  1999,  subject to the  approval  of the
shareholders of the Corporation within twelve months of such effective date (the
"Plan").  Notwithstanding anything herein to the contrary,  nothing in this Plan
shall adversely affect the rights or obligations,  under any Award granted under
the Prior Plan,  of any  grantee or holder of the Award  without  such  person's
approval.

     The  purpose  of  the  Plan  is  to  promote  the   long-term   growth  and
profitability of the Corporation by: (i) providing key people with incentives to
improve  stockholder value and to contribute to the growth and financial success
of the Corporation;  and  (ii) enabling  the Corporation to attract,  retain and
reward the best-available persons.

     The Plan permits the granting of stock options  (including  incentive stock
options qualifying under Code section 422 and nonqualified stock options), stock
appreciation  rights,  restricted or unrestricted  stock awards,  phantom stock,
performance awards, or any combination of the foregoing.

     (a) Administration of the Plan. The Plan shall be administered by the Board
or by such committee or committees as may be appointed by the Board from time to
time  (the  Board,  committee  or  committees  hereinafter  referred  to as  the
"Administrator").

     (b)  Powers of the  Administrator.  The  Administrator  shall  have all the
powers vested in it by the terms of the Plan, such powers to include  authority,
in its sole and absolute  discretion,  to grant Awards under the Plan, prescribe
Grant  Agreements  evidencing  such Awards and  establish  programs for granting
Awards.

     The  Administrator  shall have full power and  authority  to take all other
actions  necessary  to carry out the purpose and intent of the Plan,  including,
but not limited to, the  authority  to:  (i) determine  the eligible  persons to
whom, and the time or times at which Awards shall be granted; (ii) determine the
types of  Awards  to be  granted;  (iii) determine  the  number  of shares to be
covered by or used for  reference  purposes  for each  Award;  (iv) impose  such
terms,  limitations,  restrictions  and  conditions  upon any such  Award as the
Administrator  shall  deem  appropriate;  (v) modify,  amend,  extend  or  renew
outstanding Awards, or accept the surrender of outstanding Awards and substitute
new Awards (provided  however,  that,  except as provided in Section 7(d) of the
Plan, any modification  that would  materially  adversely affect any outstanding
Award shall not be made without the consent of the holder);  (vi) accelerate  or
otherwise  change the time in which an Award may be exercised or becomes payable
and to waive or accelerate the lapse, in whole or in part, of any restriction or
condition  with  respect  to such  Award,  including,  but not  limited  to, any
restriction  or condition  with respect to the vesting or  exercisability  of an
Award following  termination of any grantee's  employment or other  relationship
with the Corporation; and (vii) establish objectives and conditions, if any, for
earning  Awards and  determining  whether Awards will be paid after the end of a
performance period.

     The  Administrator  shall  have full power and  authority,  in its sole and
absolute  discretion,  to  administer  and  interpret  the Plan and to adopt and
interpret such rules,  regulations,  agreements,  guidelines and instruments for
the  administration  of the  Plan and for the  conduct  of its  business  as the
Administrator deems necessary or advisable.

     (c) Non-Uniform  Determinations.  The Administrator's  determinations under
the Plan (including without limitation, determinations of the persons to receive
Awards,  the form, amount and timing of such Awards, the terms and provisions of
such Awards and the Grant Agreements evidencing such Awards) need not be uniform
and may be made by the Administrator  selectively among persons who receive,  or
are eligible to receive,  Awards under the Plan, whether or not such persons are
similarly situated.

     (d) Limited Liability. To the maximum extent permitted by law, no member of
the Administrator  shall be liable for any action taken or decision made in good
faith relating to the Plan or any Award thereunder.

     (e)  Indemnification.  To the maximum  extent  permitted  by law and by the
Corporation's  charter and by-laws,  the members of the  Administrator  shall be
indemnified  by the  Corporation  in respect of all their  activities  under the
Plan.

     (f) Effect of Administrator's Decision. All actions taken and decisions and
determinations  made by the  Administrator  on all matters  relating to the Plan
pursuant to the powers  vested in it hereunder  shall be in the  Administrator's
sole and absolute  discretion and shall be conclusive and binding on all parties
concerned,  including the Corporation, its stockholders, any participants in the
Plan and any other employee,  consultant,  or director of the  Corporation,  and
their respective successors in interest.

4.   Shares Available for the Plan; Maximum Awards

     Subject to  adjustments  as provided in Section 7(d),  the shares of Common
Stock  that  may be  issued  with  respect  to  Awards  granted  under  the Plan
(including,  for purposes of this Section 4, the Prior Plan) shall not exceed an
aggregate of 1,175,000  shares of Common Stock.  The  Corporation  shall reserve
such  number of shares for Awards  under the Plan,  subject  to  adjustments  as
provided in Section 7(d). If any Award,  or portion of an Award,  under the Plan
expires or  terminates  unexercised,  becomes  unexercisable  or is forfeited or
otherwise terminated, surrendered or canceled as to any shares, or if any shares
of Common Stock are  surrendered to the Corporation in connection with any Award
(whether or not such  surrendered  shares were acquired  pursuant to any Award),
the shares subject to such Award and the surrendered  shares shall thereafter be
available for further Awards under the Plan;  provided,  however,  that any such
shares that are  surrendered to the  Corporation in connection with any Award or
that are otherwise  forfeited after issuance shall not be available for purchase
pursuant to incentive stock options intended to qualify under Code section 422.

     Subject to  adjustments  as provided in Section 7(d), the maximum number of
shares of Common Stock subject to Awards of any combination  that may be granted
during any one fiscal year of the  Corporation to any one individual  under this
Plan  shall be  limited  to  400,000.  Such  per-individual  limit  shall not be
adjusted to effect a restoration of shares of Common Stock with respect to which
the related Award is terminated, surrendered or canceled.

5.   Participation

     Participation  in the  Plan  shall  be  open  to all  employees,  officers,
directors,  and  consultants  of the  Corporation,  or of any  Affiliate  of the
Corporation, as may be selected by the Administrator from time to time.

6.   Awards

     The  Administrator,  in its sole  discretion,  establishes the terms of all
Awards granted under the Plan.  Awards may be granted  individually or in tandem
with other types of Awards.  All Awards are subject to the terms and  conditions
provided in the Grant Agreement.

     (a)  Stock  Options.  The  Administrator  may  from  time to time  grant to
eligible  participants Awards of incentive stock options as that term is defined
in Code  section 422 or  nonqualified  stock options;  provided,  however,  that
Awards  of  incentive  stock  options  shall  be  limited  to  employees  of the
Corporation or of any Parent or Subsidiary of the Corporation.  Options intended
to qualify as  incentive  stock  options  under  Code  section  422 must have an
exercise  price at least  equal to Fair Market  Value on the date of grant,  but
nonqualified  stock options may be granted with an exercise price less than Fair
Market  Value.  No stock  option shall be an  incentive  stock option  unless so
designated by the  Administrator  at the time of grant or in the Grant Agreement
evidencing such stock option.

     (b) Stock  Appreciation  Rights.  The  Administrator  may from time to time
grant to eligible  participants  Awards of Stock Appreciation Rights ("SAR"). An
SAR entitles the grantee to receive,  subject to the  provisions of the Plan and
the Grant Agreement, a payment having an aggregate value equal to the product of
(i) the excess of (A) the Fair Market Value on the exercise date of one share of
Common Stock over (B) the base price per share specified in the Grant Agreement,
times (ii) the number of shares specified by the SAR, or portion thereof,  which
is  exercised.  Payment by the  Corporation  of the amount  receivable  upon any
exercise of an SAR may be made by the delivery of Common  Stock or cash,  or any
combination  of Common Stock and cash, as  determined in the sole  discretion of
the Administrator.  If upon settlement of the exercise of an SAR a grantee is to
receive a portion  of such  payment  in shares of Common  Stock,  the  number of
shares shall be  determined by dividing such portion by the Fair Market Value of
a share of Common Stock on the exercise date. No fractional shares shall be used
for such payment and the  Administrator  shall  determine  whether cash shall be
given in lieu of such fractional  shares or whether such fractional shares shall
be eliminated.

     (c) Stock Awards.  The Administrator may from time to time grant restricted
or unrestricted stock Awards to eligible  participants in such amounts,  on such
terms and conditions, and for such consideration,  including no consideration or
such minimum  consideration as may be required by law, as it shall determine.  A
stock Award may be paid in Common Stock,  in cash, or in a combination of Common
Stock and cash, as determined in the sole discretion of the Administrator.

     (d) Phantom Stock. The  Administrator may from time to time grant Awards to
eligible participants denominated in stock-equivalent units ("phantom stock") in
such amounts and on such terms and  conditions  as it shall  determine.  Phantom
stock units granted to a participant shall be credited to a bookkeeping  reserve
account  solely for  accounting  purposes and shall not require a segregation of
any of the  Corporation's  assets.  An Award of phantom  stock may be settled in
Common  Stock,  in cash,  or in a  combination  of Common  Stock  and  cash,  as
determined  in the sole  discretion  of the  Administrator.  Except as otherwise
provided in the  applicable  Grant  Agreement,  the  grantee  shall not have the
rights of a stockholder  with respect to any shares of Common Stock  represented
by a phantom  stock unit solely as a result of the grant of a phantom stock unit
to the grantee.

     (e) Performance  Awards.  The Administrator  may, in its discretion,  grant
performance  awards which become payable on account of attainment of one or more
performance goals established by the  Administrator.  Performance  awards may be
paid by the delivery of Common Stock or cash, or any combination of Common Stock
and cash, as determined in the sole discretion of the Administrator. Performance
goals  established by the  Administrator may be based on the Corporation's or an
Affiliate's  operating income or one or more other business criteria selected by
the  Administrator  that  apply to an  individual  or group  of  individuals,  a
business  unit,  or the  Corporation  or an  Affiliate  as a  whole,  over  such
performance period as the Administrator may designate.

7.       Miscellaneous

     (a)  Withholding of Taxes.  Grantees and holders of Awards shall pay to the
Corporation  or  its  Affiliate,   or  make   provision   satisfactory   to  the
Administrator  for payment  of, any taxes  required to be withheld in respect of
Awards  under  the Plan no later  than the date of the  event  creating  the tax
liability. The Corporation or its Affiliate may, to the extent permitted by law,
deduct any such tax  obligations  from any payment of any kind  otherwise due to
the grantee or holder of an Award.  In the event that payment to the Corporation
or its Affiliate of such tax obligations is made in shares of Common Stock, such
shares  shall be valued at Fair  Market  Value on the  applicable  date for such
purposes.

     (b) Loans.  The Corporation or its Affiliate may make or guarantee loans to
grantees to assist grantees in exercising  Awards and satisfying any withholding
tax obligations.

     (c)  Transferability.  Except as otherwise determined by the Administrator,
and  in  any  event  in  the  case  of an  incentive  stock  option  or a  stock
appreciation  right granted with respect to an incentive stock option,  no Award
granted under the Plan shall be transferable by a grantee otherwise than by will
or the laws of descent and  distribution.  Unless  otherwise  determined  by the
Administrator  in  accord  with  the  provisions  of the  immediately  preceding
sentence,  an Award may be exercised during the lifetime of the grantee, only by
the grantee or,  during the period the grantee is under a legal  disability,  by
the grantee's guardian or legal representative.

     (d)  Adjustments;  Business  Combinations.  In the event of  changes in the
Common  Stock of the  Corporation  by reason of any  stock  dividend,  spin-off,
split-up,  recapitalization,  merger,  consolidation,  business  combination  or
exchange of shares and the like, the  Administrator  shall,  in its  discretion,
make  appropriate  adjustments to the maximum number and kind of shares reserved
for issuance or with  respect to which  Awards may be granted  under the Plan as
provided in  Section 4  of the Plan and to the number,  kind and price of shares
covered by  outstanding  Awards,  and shall,  in its  discretion and without the
consent of holders of Awards,  make any other adjustments in outstanding Awards,
including but not limited to reducing the number of shares  subject to Awards or
providing or mandating alternative  settlement methods such as settlement of the
Awards  in  cash or in  shares  of  Common  Stock  or  other  securities  of the
Corporation  or of any other  entity,  or in any other  matters  which relate to
Awards as the  Administrator  shall,  in its sole  discretion,  determine  to be
necessary or appropriate.

     Notwithstanding  anything  in the  Plan to the  contrary  and  without  the
consent of holders of Awards,  the  Administrator,  in its sole discretion,  may
make any modifications to any Awards, including but not limited to cancellation,
forfeiture,  surrender  or other  termination  of the Awards in whole or in part
regardless  of the  vested  status  of the  Award,  in order to  facilitate  any
business combination that is authorized by the Board to comply with requirements
for  treatment as a pooling of interests  transaction  for  accounting  purposes
under generally accepted accounting principles.

     The  Administrator is authorized to make, in its discretion and without the
consent of holders of Awards,  adjustments  in the terms and  conditions of, and
the  criteria  included in,  Awards in  recognition  of unusual or  nonrecurring
events affecting the Corporation, or the financial statements of the Corporation
or any Affiliate, or of changes in applicable laws,  regulations,  or accounting
principles,  whenever the  Administrator  determines  that such  adjustments are
appropriate  in order to prevent  dilution  or  enlargement  of the  benefits or
potential benefits intended to be made available under the Plan.

     (e)  Substitution  of Awards in  Mergers  and  Acquisitions.  Awards may be
granted  under the Plan from time to time in  substitution  for  Awards  held by
employees or  directors of entities who become or are about to become  employees
or  directors  of the  Corporation  or an Affiliate as the result of a merger or
consolidation of the employing  entity with the Corporation or an Affiliate,  or
the acquisition by the Corporation or an Affiliate of the assets or stock of the
employing  entity.  The terms and conditions of any substitute Awards so granted
may vary from the terms and  conditions  set forth herein to the extent that the
Administrator  deems  appropriate at the time of grant to conform the substitute
Awards to the provisions of the awards for which they are substituted.

     (f)  Termination,  Amendment and  Modification  of the Plan.  The Board may
terminate, amend or modify the Plan or any portion thereof at any time.

     (g)  Non-Guarantee of Employment or Service.  Nothing in the Plan or in any
Grant Agreement  thereunder  shall confer any right on an individual to continue
in the service of the  Corporation or shall  interfere in any way with the right
of the  Corporation  to terminate such service at any time with or without cause
or notice.

     (h) No Trust or Fund  Created.  Neither the Plan nor any Award shall create
or be  construed  to create a trust or separate  fund of any kind or a fiduciary
relationship  between the Corporation and a grantee or any other person.  To the
extent that any  grantee or other  person  acquires a right to receive  payments
from the Corporation  pursuant to an Award,  such right shall be no greater than
the right of any unsecured general creditor of the Corporation.

     (i) Governing  Law. The validity,  construction  and effect of the Plan, of
Grant  Agreements  entered  into  pursuant  to  the  Plan,  and  of  any  rules,
regulations,  determinations or decisions made by the Administrator  relating to
the Plan or such Grant Agreements,  and the rights of any and all persons having
or claiming to have any  interest  therein or  thereunder,  shall be  determined
exclusively in accordance with applicable federal laws and the laws of the State
of Maryland without regard to its conflict of laws principles.

     (j) Effective Date;  Termination Date. The Plan is effective as of April 5,
1999,  the date on which the Plan, as an amendment and  restatement of the Prior
Plan, was approved by the Board,  subject to the approval of the stockholders of
the  Corporation  within twelve months of such effective date. No Award shall be
granted under the Plan after the close of business on June 30, 2005.  Subject to
other applicable provisions of the Plan, all Awards made under the Plan prior to
such  termination of 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.


Date Approved by the Stockholders:  May 27, 1999.
