                (As Amended and Restated Effective April 5, 1999)

          1.  Restatement,  Purpose  and Types of Awards GSE  Systems,  Inc.,  a

     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.

     wards 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

     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

     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.

     Administrator shall be liable for any action taken or decision made in good

     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.
