     COLLATERAL  ASSIGNMENT made as of this 26 day of April, 2006 by Gulf Coast
Oil  Corporation  ("Assignor")  to  Laurus  Master  Fund,  Ltd.  ("Assignee").

     FOR  VALUE  RECEIVED, and as collateral security for all debts, liabilities
and obligations of Assignor to Assignee, now existing or hereafter arising under
that  certain  Securities Purchase Agreement dated as of the date hereof between
Assignor  and Assignee (the "SPA") and the Related Agreements (as defined in the
SPA)  (each  as  amended, modified, restated or supplemented from time to time),
Assignor  hereby  assigns, transfers and sets over unto Assignee, its successors
and  assigns,  all  of  its  rights, but not its obligations, under that certain
Asset  Purchase  Agreement dated as of April  28,  2006  by  and  between  Manti
Resources,  Inc.,  Manti   Operating  Company  and  Manti  Mustang  Creek,  Ltd.
("Seller")  and Assignor and all of the agreements and documents by which assets
or  rights  of  Seller  are  transferred  to  Assignor  (as each may be amended,
modified,  restated  or  supplemented  from  time  to  time,  collectively,  the
"Agreements"),  including,  without  limitation,  all  indemnity  rights and all
moneys  and  claims  for  moneys  due and/or to become due to Assignor under the
Agreements.

     Assignor  hereby (i) specifically authorizes and directs Seller upon notice
to  Seller  by  Assignee  to  make all payments due to Assignor under or arising
under  the  Agreements  directly to Assignee and (ii) irrevocably authorizes and
empowers  Assignee (a) to ask, demand, receive, receipt and give acquittance for
any  and  all amounts which may be or become due or payable, or remain unpaid at
any  time  and times to Assignor by Seller under and pursuant to the Agreements,
(b)  to  endorse  any  checks,  drafts  or other orders for the payment of money
payable to Assignor in payment thereof, and (c) in Assignee's discretion to file
any  claims  or  take  any action or institute any proceeding, either in its own
name  or in the name of Assignor or otherwise, which Assignee may deem necessary
or advisable to effectuate the foregoing. It is expressly understood and agreed,
however,  that Assignee shall not be required or obligated in any manner to make
any demand or to make any inquiry as to the nature or sufficiency of any payment
received  by  it,  or  to  present or file any claim or take any other action to
collect  or  enforce  the payment of any amounts which may have been assigned to
Assignee  or  to  which Assignee may be entitled hereunder at any time or times.

     Seller  is  hereby  authorized  to  recognize  Assignee's  claims to rights
hereunder  without  investigating any reason for any action taken by Assignee or
the  validity  or  the amount of the obligations or existence of any default, or
the  application  to  be  made  by  Assignee of any of the amounts to be paid to
Assignee.  Checks  for all or any part of the sums payable under this Assignment
shall  be  drawn  to  the  sole and exclusive order of Assignee. Upon payment by
Seller  to  Assignee  of  any amounts due to Assignor under or arising under the
Agreements,  the  obligations of Seller to Assignor with respect to such amounts
shall  be  deemed  paid  in  full.

     Without  first  obtaining  the  written  consent  of Assignee, Assignor and
Seller  shall  not  amend  or  modify  the  Agreements.

     In the event Assignor declines to exercise any rights under the Agreements,
Assignee  shall  have  the  right to enforce any and all such rights of Assignor
directly  against  Seller.

     IN  WITNESS  WHEREOF, Assignor has duly executed this Collateral Assignment
the  day  and  year  first  above  written.

<PAGE>Exhibit 10.12

                                    AGREEMENT

     THIS  AGREEMENT  is  made  as  of  April 28,  2006  among  Gulf  Coast Oil
Corporation, a Delaware corporation (THE "COMPANY"), New Century Energy Corp., a
Colorado  corporation  (the  "PARENT"), and Laurus Master Fund, Ltd. ("LAURUS").

     WHEREAS,  the  Company  has  issued  a  Common  Stock  Purchase Warrant (as
amended, modified or supplemented from time to time, the "WARRANT") to Laurus to
purchase  up to 49% of the common stock of the Company (subject to adjustment as
set  forth  therein).

     NOW  THEREFORE,  for  good  and  valuable  consideration,  the  receipt and
sufficiency  of  which  is  hereby  acknowledged,  the parties agree as follows:

1.   SHAREHOLDERS  AGREEMENT. Forthwith following the exercise of the Warrant in
     -----------------------
     whole  or  in  part  pursuant  to  Section  1.1 of the Warrant, each of the
     Parent,  the  Company and Laurus agree to negotiate in good faith the terms
     of  a shareholders agreement mutually agreeable to each of them, which such
     shareholder  agreement  shall include, without limitation, (a) such matters
     commonly  provided  for in a shareholders agreement, such as governance and
     transfer  restrictions  and  (b)  Laurus'  required  consent  to any of the
     Designated  Actions  (as  hereafter defined). For purposes hereof, the term
     "Designated Actions" shall have the meaning set forth on Schedule A hereto.
                                                              ----------

2.   DIVIDEND.  Following  the  exercise by Laurus of the Warrant in whole or in
     --------
     part,  as  the  Company  receives  cash  attributable  to  Net  Revenue (as
     hereafter defined ) (the "Net Revenue Proceeds"), the Parent (to the extent
     permitted by applicable law) shall, and shall cause the Company to, declare
     and  pay a dividend to its shareholders, but in no event shall the dividend
     payable to Laurus be less than (i) Laurus' percentage ownership interest in
     the Company at such time times (ii) the Net Revenue Proceeds so received by
                              -----
     the  Company.  Such dividend shall be remitted by the Company to Laurus not
     later  than  two  (2)  business days following the day on which the Company
     receives  such  Net  Revenue  Proceeds  and  pursuant  to  such  remittance
     instructions  as  Laurus  shall  designate  to  the Company in writing. For
     purposes  hereof,  the  term "Net Revenue" means the gross proceeds paid to
     the  Company  in respect of oil, gas and/or other hydrocarbon production in
     which the Company has an interest whether or not such proceeds are remitted
     to  the lockbox account and/or any other blocked account established by the
     Company  in connection with the transactions contemplated hereby net of, in
     each case, with respect to the period for which Net Revenue relates (i) the
     reasonable  ordinary  day  to  day  expenses  associated with the Company's
     operation  of  the  leases, wells and equipment, including fuel, materials,
     labor,  maintenance,  routine  production  equipment  replacement, repairs,
     routine  workover  costs  to maintain production from an existing completed
     well,  royalty,  severance  tax  and  ad  valorem  tax,  in each case using
     accounting  practices  and procedures ordinary and customary in the oil and
     gas  industry and (ii) the Company's reasonable estimate of its federal tax
     (including  federal  income  tax)  liability (after taking into account all
     applicable  deductions,  depletions and credits), all of which, in the case

<PAGE>

     of  the foregoing clauses (i) and (ii) shall be subject to Laurus' approval
     which  shall  be  provided in the exercise of Laurus' reasonable discretion
     based  on  such  supporting  documentation from the Company as Laurus shall
     request.

3.   TERM OF  AGREEMENT. This Agreement shall be effective for so long as Laurus
     ------------------
     holds  the  Warrant  or  any portion thereof or any shares of the Company's
     common stock acquired upon the exercise of the Warrant in whole or in part.

4.   GOVERNING  LAW.  This  Agreement  shall  be  governed  by and construed and
     --------------
     enforced  in  all  respects in accordance with the laws of the State of New
     York.

5.   COUNTERPARTS.  This  Agreement may be executed in one or more counterparts,
     ------------
     each  of  which  shall  be  deemed  an original and all of which when taken
     together  shall  constitute  one  and  the  same  agreement.  Any signature
     delivered by a party by facsimile transmission or by sending a scanned copy
     by  electronic  mail  shall  be  deemed  an  original  signature  hereto.
