      INITIAL WELL

	 	 
		
      On or before May 31st, 2006, or such other mutually
      agreed date, the Farmee shall participate in the drilling of a minimum of
      one well (the “Initial Well”) substantially on the terms set out in
      the Operating Agreement. The Farmee shall have the option but not the
      obligation to earn up to a 25% Working Interest (WI) in the Initial Well
      by paying up to 33.33% of all costs and expenses incurred for the joint
      account under the Operating Agreement respecting the drilling and
      completion of said Well to its objective depth.

	 	 
		
      Star shall provide notice to the Farmee of the drilling
      of the Initial Well together with the Authority for Expenditure as
      described below therefore required at least 15 days prior to the
      anticipated spud date of the Well, and the Farmee shall have 7 days from
      receipt of such notice to elect by notice in writing to Star to
      participate in that Well. Failure to respond within such 7-day period
      shall be deemed an election by the Farmee not to participate. If the
      Farmee elects or is deemed to elect not to participate in a Well the
      Farmee shall maintain their right to participate in any Well proposed
      thereafter.

	 	 
		
      Once the Initial Well has been drilled to its objective
      depth the Farmee shall have the right to elect, upon receiving all
      information available in respect of the Initial Well, to participate in
      the setting of production casing for and completion of the Initial Well as
      described in the Authority for Expenditure. If the Farmee elects not to
      participate in the proposed casing and completion of the Initial Well and
      such operation is carried out, the Farmee shall be subject to those
      penalties applicable pursuant to the Operating
Agreement.

If all parties with an interest in the
Initial Well elect to abandon it, the Farmee shall pay its WI share of all costs
associated with the plugging and abandoning the Initial Well. 

	3. 	
      EARNING

	 	 
		
      Upon the drilling of the Initial Well to its objective
      depth pursuant to Clause 2 above, the Farmee will be deemed to have earned
      a Working Interest in said Initial Well, and in the AMI as described in
      Clause 4 below.

	 	 
	4. 	
      RIGHT TO PARTICIPATE

	 	 
		
      Upon the drilling of the Initial Well to its objective
      depth pursuant to Clause 2 above the Farmee will have earned the right to
      participate in additional Wells to be drilled by Star within the AMI
      located in Wise, Denton and Jack Counties in the State of Texas, USA, for
      a period of 24 months from the date of signing of this Agreement, on the
      same general terms as the Initial Well.

	 	 
		
      Additional Wells will generally be located on leased
      lands in Wise, Denton and Jack Counties in the State of Texas, USA. It has
      been proposed that the Wells are to be drilled at the rate of one Well per
      month over the next 24 months. The parties acknowledge that the location
      and objective depth of the Wells described above may change from time to
      time and that it is the intention of the parties that the Farmee has the
      option to participate in up to 24 Wells in accordance with the terms of
      this Participation Agreement.

	 	 
		
      From time to time the Farmee may wish to elect not to
      participate in a Well but shall nonetheless retain the right to
      participate in any subsequent Well in accordance with the terms of this
      Participation Agreement. Nothing herein shall require the Farmee to
      participate or to earn an interest in any future Wells.

	 	 
	5. 	
      COSTS

	 	 
		
      The estimated gross costs for horizontal drilling
      and completion attempts per Well is approximately
      $2,200,000-$2,500,000. The Project Payment, per 1% WI
      participation, is based on 75% Working Interest participants paying 100%
      of the actual drilling and completion costs as indicated in the Operating
      Agreement.

	 	 
	6. 	
      AUTHORIZATION FOR EXPENDITURE

	 	 
		
      An Authorization for Expenditure for any one Well shall
      be forwarded to the Farmee prior to commencement of drilling operations in
      respect of it. This Authorization for Expenditure shall represent the
      Operator’s good faith estimate of the costs of the Well, and Star shall
      have the right from time to time to demand and receive from the Farmee no
      earlier than 30 days prior to the expected spud date of each Well in which
      the Farmee elects to participate, payment in advance of the Farmee's
      respective share of the Authorization of Expenditure for the Well as to
      all amounts up to but not including casing of the Well.

	 	 
		
      The Farmee shall pay the full amount of the payment so
      invoiced prior to commencement of drilling operations for that Well. Star
      shall only use such monies for the Well in question, and shall immediately
      return such monies to the Farmee if the Well is not drilled or if the
      monies delivered are in excess of what is required for Farmee's
      proportionate share of the aforesaid Well drilling
  expenses.

	7. 	
      OPERATING AGREEMENT

	 	 
		
      All operations will be conducted in accordance with the
      terms and provisions of the Operating Agreement. Star is designated as
      Operator of the Well. The Operator will have the right to receive the
      revenues due the Working Interest owners of the Well and deduct operating
      and other expenses from the revenue prior to distribution of the revenues.
      Such provision, however, shall not relieve the Farmee of any personal
      liability for paying the operating and other expenses attributable to the
      Well. Star shall have the right to enter into a Gas Purchase Contract
      binding 100% of the Working Interest owners on said terms and conditions,
      as Star deems reasonable.

	 	 
		
      The Operator has the sole right and discretion, at any
      time and for any reason including new geological information, leasehold
      title, leasehold availability, gas market availability, contractual
      commitments, prior sales of a designated leasehold interest to another, to
      substitute re-entry or drillsite locations and/or refuse to re-enter or
      drill the Well. In the event of a substitution, the funds for such well
      that have been contributed shall be used for the purposes of re-entering
      or drilling and possibly completing the substitute well or wells. In the
      event the Operator decides not to re-enter or drill the well and does not
      substitute a well or wells, the Operator shall forthwith return such funds
      after all cost overages, if any, of the well(s) that have been re-entered
      or drilled have been determined and the funds are first applied to such
      overages to extinguish the same.

	 	 
	8. 	
      REPRESENTATIONS AND WARRANTIES

	 	 
		
      PB and Star make no representation concerning the
      probable success of the drilling and completion attempts of the Wells and
      the Farmee acknowledges that it has made its own evaluation of the
      probable success of such drilling, testing, and completion attempts of the
      Wells and that the Farmee is highly familiar with oil and gas operations
      and risks.

	 	 
	9. 	
      RISK

	 	 
		
      Farmee is advised that its participation in the working
      interest set forth herein involves a high degree of risk. The Farmee
      represents that it has read all documents including, but not limited to,
      this Participation Agreement, estimated reserves and cash flow statements,
      and the Operating Agreement very carefully, and that it has a high degree
      of familiarity with oil and gas investments and that it is willing and
      able to bear the economic risks of an investment in the amount equal to
      the amount purchased.

	 	 
	10.

      This Participation Agreement and its terms shall not be
      assigned and/or sold without the prior written consent of the parties

      subsequently transfers any interest or portion of an interest acquired
      herein, the Farmee agrees to comply with all Laws regarding such transfer
      and agrees to indemnify and hold Star, it’s officers, and employees
      harmless from any claims or causes of action which may be brought by any
      third party to whom the Farmee assigned its Working Interest. Such
      indemnity shall extend to and include any out-of-pocket costs and
      attorney’s fees incurred by Star or it’s officers and
  employees.

Star Of Texas Energy Services, Inc. “Star Of Texas” represents
that it has Working Interest in the 211.8 acre Malcolm-Star #1H gas unit located
in the E.C. Allender Survey, A-16, Wise County, Texas.

1. Explortex Energy Inc. agrees to purchase 1% Working Interest
consisting of a portion of Star Of Texas’ Working Interest in the Malcolm-Star
#1H gas unit and to join in the horizontal drilling and completion attempt of
the Well to true vertical depth of 8700’, or to depths sufficient to test the
Barnett Shale, whichever is the lesser depth subject to the terms and conditions
as set forth herein. The current gross net revenue interest percentage for the
well is 75%.

The estimated cost for the horizontal drilling and
completion attempt (“PROJECT PAYMENT”) is based on a cost of $35,532.00 per
1% WI participation in which the 75% WI participants pay 100% of the
drilling and completion costs indicated in Exhibit “A”. The Project Payment due
date is indicated below. The cash payment should be made payable to “STAR OF

substitute well or wells. In the event the operator decides not to re-enter or
drill the well and does not substitute a well or wells, the operator shall
forthwith return such funds after all cost overages, if any, of the well(s) that
