     3.      Further  Provisions
             -------------------

     3.1     THIS  AGREEMENT  IS  INTENDED  TO  ALLOW  TIME  FOR THE PARTIES TO
             -------------------------------------------------------------------
EXPLORE  POSSIBLE  ALTERNATIVES  TO  THE  CURRENT  STRUCTURE  OF  EXXONMOBIL'S
--------------------------------------------------------------------------------
ARRANGEMENT  WITH  HARDING  UNDER THE EXPLORATION AGREEMENT AS NOTED IN THE LAST
--------------------------------------------------------------------------------
RECITAL  SET  FORTH  ABOVE;  PROVIDED,  HOWEVER,  THIS  AGREEMENT  SHALL  NOT BE
--------------------------------------------------------------------------------
CONSTRUED  TO  CREATE,  AND SHALL NOT CREATE, ANY LEGALLY BINDING OBLIGATIONS OR
--------------------------------------------------------------------------------
COMMITMENTS  ON  THE PART OF ANY PARTY TO REACH OR ATTEMPT TO REACH AGREEMENT ON
--------------------------------------------------------------------------------
SUCH  ALTERNATIVES  (INCLUDING  ANY  STRUCTURES OR GOALS REFERENCED IN THE ABOVE
 -------------------------------------------------------------------------------
RECITALS),  IT BEING EXPRESSLY UNDERSTOOD AND AGREED THAT ANY PARTY MAY WITHDRAW
--------------------------------------------------------------------------------
FROM  AND  CEASE SUCH DISCUSSIONS AT ANY TIME AT ITS SOLE OPTION AND DISCRETION,
--------------------------------------------------------------------------------
AND  WITHOUT  ANY  LIABILITY  TO  THE  OTHER  PARTIES  AS  A  RESULT  THEREOF.
-----------------------------------------------------------------------------

     3.2     Except  for  the  extensions  of  the  deadlines  for ExxonMobil to
exercise  the Preferential Purchase Right as provided in Paragraph 1 and without
limiting,  releasing  or  impairing  the  parties'  respective obligations under
Paragraphs  2,  3.1., 3.3, 3.4, 3.5 and 3.6, this Agreement shall not constitute
or be construed as a waiver or release by any party to this Agreement any of its
rights  and  remedies,  if  any,  under the Exploration Agreement, the aforesaid
Operating  Agreement  or  any other agreement or at law or in equity, including,
without  limitation, its rights, if any, set forth in the PetroSearch Agreement,
the  Eagle  Agreement  and  the  and  PSG Agreement and its rights regarding the
granting  or  withholding  of  consent  or  approval  with  respect  thereto.

     3.3     ExxonMobil believes that the 30-day period during which ExxonMobil
was originally entitled to exercise the Preferential Purchase Right with respect
to Harding's proposed sale of an interest in the Leases pursuant the PetroSearch
Agreement  (the  "Original  30-Day Election Period") commenced on March 1, 2006,
making  March  31,  2006,  the last day of such Original 30-Day Election Period.
PetroSearch, however, believes that the Original 30-Day Election Period may have
commenced prior to March 1, 2006, resulting in the termination prior to the date
of  this  Agreement of the Preferential Purchase Right with respect to Harding's
proposed  sale  of an interest in the Leases pursuant the PetroSearch Agreement.
This  Agreement  shall not constitute or be construed as a waiver or release (a)
by PetroSearch of its right to claim or assert that the Original 30-Day Election
Period  commenced  prior  to  March  1, 2006, and that the Preferential Purchase
Right  with  respect  to  Harding's  proposed  sale of an interest in the Leases
pursuant  the  PetroSearch  Agreement  has  already  expired as a result of such
alledged  earlier  commencement  date or (b) by ExxonMobil of any of its rights,
claims,  defenses and remedies in connection with any such claim or assertion by
PetroSearch.  Notwithstanding  the


<PAGE>
foregoing,  PetroSearch  agrees  that  if  the  Original  30-Day Election Period
commenced  on  March  1,  2006,  then this Agreement shall operate to extend the
deadline for ExxonMobil to exercise the Preferential Purchase Right with respect
to Harding's proposed sale of an interest in the Leases pursuant the PetroSearch
Agreement  to  May  2,  2006.

     3.4     If ExxonMobil does not exercise the Preferential Purchase Right on
or  before the PetroSearch Deadline (as the same may be subsequently extended by
mutual  agreement  of ExxonMobil, Harding and PetroSearch), then ExxonMobil will
give  its  consent to the assignment of interests in the Leases, the Exploration
Agreement  and  said Operating Agreement from Harding to PetroSearch pursuant to
the  PetroSearch  Agreement,  but only if and to the extent that PetroSearch and
Harding comply with, and amend the PetroSearch Agreement to the extent necessary
to  comply with, the requirements of the Exploration Agreement and the aforesaid
Operating  Agreement.

     3.5     This  Agreement  and the transactions contemplated hereby shall be
construed  in  accordance with, and governed by, the laws of the State of Texas,
without  regard to conflict of laws principles.  All disputes, controversies, or
claims  (whether  contractual, tortious, equitable, statutory or otherwise) that
may  arise  among  the  parties  arising  out  of or in any way relating to this
Agreement  shall  be  finally  and  exclusively submitted to, and determined by,
binding  arbitration pursuant to and in the manner provided in Article 32 of the
Exploration  Agreement  as  if references in said Article 32 to "this Agreement"
were  to  this Agreement rather than to the Exploration Agreement and references
in  said  Article  32  to "Party" or "Parties" were to a party or the parties to
this  Agreement,  as  the  case  may  be,  which  arbitration  provisions  are
incorporated  herein  for  all  purposes.

     3.6     This  Agreement  may  be  executed  by  signing  the original or a
counterpart  hereof.  In  the  event  this  Agreement or counterparts hereof are
circulated and executed by facsimile transmission, the signatures of the parties
shall  be  considered  as  original  and self-proving for all purposes under the
applicable  law.  If  this  Agreement  is  executed  in  multiple  counterparts
(including  execution  of counterparts via facsimile), each counterpart shall be
deemed  an  original,  and all of which when taken together shall constitute but
one and the same agreement with the same effect as if all parties had signed the
same  instrument.  This  Agreement shall not become effective unless the parties
execute  and  return  this  Agreement  to  ExxonMobil  by  faxing  an  executed
counterpart  of  this  Agreement  to  ExxonMobil at 281-654-4131 by 6:00 P.M. on
March 30, 2006; provided, however, if ExxonMobil, Harding and at least one other
party  execute  and  return this Agreement to ExxonMobil by such time, then this
Agreement  shall  become effective as to all parties who execute and return this
Agreement  to  ExxonMobil  by  such  time.

     IN  WITNESS  WHEREOF,  the  parties  hereto have executed this Agreement in
multiple  counterparts  as  of  the  date  first  above  written.
