                           FOURTH AMENDMENT AGREEMENT

     THIS  FOURTH  AMENDMENT  AGREEMENT (this "Amendment") is entered into as of
May  2,  2006,  by  and between New Century Energy Corp., a Colorado corporation
("NCEC"),  and  Laurus  Master  Fund,  Ltd.  ("Laurus").

                                   BACKGROUND

     NCEC and Laurus are parties to (a) a Securities Purchase Agreement dated as
of  June 30, 2005 (as amended, restated, supplemented or otherwise modified from
time to time, the "June 2005 SPA"); (b) a Securities Purchase Agreement dated as
of  September 19, 2005 (as amended, restated, supplemented or otherwise modified
from  time  to  time,  the "September 2005 SPA" together with the June 2005 SPA,
each  a  "Purchase  Agreement"  and  collectively,  the  "Purchase  Agreements")
pursuant  to  which  Laurus provided NCEC with certain financial accommodations;
and  (c) NCEC and Laurus are parties to a Registration Rights Agreement dated as
of  June 30, 2005 (as amended, restated, supplemented or otherwise modified from
time to time, the "Registration Rights Agreement") pursuant to which NCEC, among
other  things,  has  agreed  to  file  a  registration  statement  covering  the
Registrable  Securities  (as  therein  defined).

     In  connection  with  the  (a)  June  2005  SPA,  NCEC  executed  a Secured
Convertible  Term  Note  dated  as  of  June  30, 2005 in favor of Laurus in the
original  principal amount of $15,000,000 (as amended, restated, supplemented or
otherwise  modified  from  time  to  time)  and (b) the September 2005 SPA, NCEC
executed  a  Secured Term Note dated as of September 19, 2005 in favor of Laurus
in  the  original  principal  amount  of  $9,500,000  (as  amended,  restated,
supplemented  or  otherwise  modified  from  time  to  time).

     In  April 2006, NCEC's wholly owned subsidiary, Gulf Coast Oil Corporation,
a  Delaware  corporation  ("Gulf  Coast"),  entered  into  a Securities Purchase
Agreement  with Laurus (the "Gulf Coast Securities Purchase Agreement"), whereby
Gulf  Coast  sold  a  $40,000,000  Secured  Term Note to Laurus (the "Gulf Coast
Note")  and  a  Common  Stock  Purchase  Warrant (the "Gulf Coast Warrant"), and
entered  into  various  other  Related  Agreements, as defined in the Gulf Coast
Securities  Purchase  Agreement  (the  "Gulf  Coast  Related  Agreements"). NCEC
guaranteed  all of Gulf Coasts obligations and liabilities to Laurus pursuant to
a  Guaranty  (as amended, restated, supplemented or otherwise modified from time
to  time,  the  "NCEC  Guaranty").

     NCEC  and  Laurus have agreed to amend the Registration Rights Agreement on
the  terms  and  conditions  hereafter  set  forth.

     NOW,  THEREFORE, in consideration of the parties' entry into the Gulf Coast
Purchase  Agreement,  the  Gulf  Coast  Related Agreements, the sale of the Gulf
Coast  Note and the Gulf Coast Warrant, and NCEC's entry into the NCEC Guaranty,
and  for  other  good and valuable consideration, the receipt and sufficiency of
which  are  hereby  acknowledged,  the  parties  hereto hereby agree as follows:
