         This Agreement is entered into on April 25, 2001 by and between
Knowledge Transfer Systems, Inc. ("KTSI") and Jennifer L. Brenner
("Shareholder").

          1.   KTSI is a  publicly  held  company  currently  trading on the OTC
               market under the ticker symbol KTSI.  KTSI was formerly  known as
               GoThink!.com. Inc.

          2.   Shareholder  has  provided  services  to KTSI  during the past 12
               months  either as an  employee,  contractor  or  consultant.  The
               parties  stipulate  to the  value  of  these  services  as  being
               $100,000.

          3.   Shareholder  has not received  any payment or other  remuneration
               for the provision of these services to KTSI.

          4.   As full payment of the services  provided by Shareholder to KTSI,
               the parties agree and  stipulate  that  Shareholder  will receive
               2,000,000  shares ("the  Shares") of common  stock of KTSI.  KTSI
               will agree to register, on behalf of Shareholder the Shares under
               Regulation  S-8, so that the Shares will  become  "free  trading"
               shares.

          5.   In  addition  to  the  Shares,   the  parties  have  agreed  that
               Shareholder  will  purchase an additional  2,000,000  shares (the
               "Purchase  Shares") of KTSI common stock at a purchase price of 5
               cents per shares,  for a total  purchase  price of $100,000.  The
               payment  for  such  shares  shall  be  made  in  the  form  of  a
               non-recourse  promissory  note issued by  Shareholder in favor of
               KTSI which note shall be due and  payable on December  31,  2003.
               The  Purchase  shares  shall be issued by KTSI  immediately,  but
               shall be restricted  under  applicable  securities laws and shall
               also be subject to a  "Lockup/Leakout"  agreement  with KTSI for
               a period of 24 months, in a form suitable to both parties.

          6.   The  parties  both  release  each  other from all other forms of
               compensation  or  obligations  except for the obligations
               specifically   referenced   herein,   and Shareholder   agrees
               that   he/she   has  been  fully compensated  for all  services
               rendered  on  behalf of KTSI, or its predecessor.

          7.   This agreement shall be governed in accordance with Nevada law,
               and shall govern all matters related to the issues contained
               herein.
