ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     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'

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.

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 23, 2005. 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, GP Strategies' Chairman and Chief
Executive Officer.

Officer is also  Chairman of the Board of the Company.  Scott N.  Greenberg,  GP
Strategies'  President  and  Chief  Financial  Officer  and  director  is also a
