Mr. David J. Tudor
Executive Vice President
Vesta Natural Gas Company

Tulsa, Oklahoma  74103

Dear David:

This letter (the "Settlement Letter") states the principles of the agreement
between Vesta Natural Gas Company ("VNG") and Laclede Gas Company
("Laclede") to resolve their respective present disputes, claims or causes
of action arising out of or related to the subject matter (the "Subject
Matter") of the November 1, 1990 Gas Purchase and Sales Agreement (the
"Agreement") by and between Laclede and ESCO Energy, Inc. (now known as
Vesta Natural Gas Company).

Effective November 1, 1990 Laclede and VNG entered into the Agreement,
pursuant to which Laclede was to purchase up to 55,000 MMBtu/day of natural
gas from VNG and VNG was to sell the same to Laclede for a term beginning
November 1, 1990 and for a primary term ending October 31, 2000.  Laclede
and VNG have conducted natural gas business pursuant to the Agreement since
November 1, 1990.

The Agreement contains a section (Article VI, paragraph 3), which Laclede
and VNG have referred to as the "Pricing Cap Provision."  The Pricing Cap
Provision delineates a method pursuant to which the "Contract Year" total
aggregate price paid by Laclede to VNG is limited to the cost Laclede
". . . would have incurred during the same period had all Base Volumes been
purchased from MRT under its Rate Schedule CD-1."  The initials MRT refer to
Mississippi River Transmission Corporation which is an interstate pipeline
company that delivers gas to Laclede.

On November 1, 1993 MRT revised its interstate pipeline tariff pursuant to
Federal Energy Regulatory Commission Order No. 636 ("FERC Order 636").  The
revised tariff does not reflect an "MRT Rate CD-1."  FERC Order 636
prohibits an interstate natural gas pipeline from establishing or charging a
rate in the nature of the MRT Rate CD-1, which was a "bundled rate."

Laclede and VNG have asserted differing opinions about the effect of FERC
Order 636 on the Pricing Cap Provision.  VNG has asserted that the
prohibition of a "bundled rate" has removed the MRT Rate CD-1 and therefore
the Pricing Cap Provision no longer is applicable.  Laclede has asserted
that 

  
                                    69
   
the Pricing Cap Provision is still applicable, however that a "restructured"
Pricing Cap must be applied.  Laclede and VNG also differ on their
respective obligations under the Agreement (Article VI, paragraph 6)
regarding transportation under the Agreement on and after November 1, 1996. 
Throughout the course of such disputes, assertions have arisen as to other
claims or causes of action related to the Subject Matter.

In consideration of the mutual promises and other considerations stated
herein, Laclede and VNG have agreed to settle their Pricing Cap Provision
dispute and other present disputes, claims or causes of action of any kind
in any way related to the Subject Matter in accordance with the following
terms and conditions:

     1.  This Settlement Letter is specifically contingent upon the          
     "Closing" of the Missouri Pipeline Company and Missouri Gas Company     
     asset sale to Utilicorp United, Inc., as addressed in Missouri          
     Public Service Commission Case No. GM-94-252, in which Laclede is       
     an Intervenor (the "Closing").  In the event the Closing does not       
     occur on or before 5:00 P.M., C.S.T., January 31, 1995, then this       
     Settlement Letter shall be deemed null and void and neither VNG nor     
     Laclede shall be bound by the terms and conditions set forth            
     herein.

     2.  As final and total settlement of VNG's refund obligation under the  
     Agreement through October 31, 1994, VNG agrees to pay Laclede and       
     Laclede agrees to accept $2,410,000 (the "Settlement Payment").         
     The Settlement Payment shall be paid by wire transfer to be             
     received by Laclede within one business day after the date of           
     "Closing".

     3.  Effective November 1, 1994, Article VI of the Agreement shall be    
     revised as follows:

     a)  Amend paragraph 3 to limit VNG's refund obligations for the         
     contract years beginning November 1, 1994 and November 1, 1995 to $2.1  
     million and $2.0 million respectively.

     b)  Amend paragraph 3 to provide that the calculation and comparison of 
     costs required by such paragraph 3 shall be made comparing:

          (i)  Laclede's actual gas costs for delivery of gas from the MRT   
          system, calculated in accordance with the method reflected in      
          Amended Schedule II (which is attached and replaces Schedule II    
          attached to the Agreement);

                                with
          (ii)  the annual calculation of Seller's charges to Buyer          
          calculated in accordance with Schedule I attached to the           
          Agreement.

     Each contract quarter, Laclede shall be required to provide VNG with    
     comparison of cost data and such other information as may be reasonably 
     necessary for VNG to ascertain the then current status of any refund    
     exposure.  Upon reasonable notice, and no more than once a year, VNG    
     shall have the right to audit reasonably Laclede's records to verify    
     the accuracy of data supporting the comparison calculations, including, 
     but not limited to, gas purchase costs and MRT pipeline statements.     
                                      2
                                    70
   
     Such audit right may be exercised only by VNG utilizing a third party   
     mutually agreeable to VNG and Laclede.  Any costs related to such       
     audit will be borne by VNG.

     c)  Amend paragraph 3 to provide that refunds for contract years        
     beginning November 1, 1994 and November 1, 1995 shall be accomplished   
     by the application of an invoice credit, equal to the total refund due  
     for the contract year, to the invoices presented to Laclede by VNG for  
     October 1995 and October 1996 deliveries, respectively.  Paragraph 3    
     shall be further amended to provide that Laclede shall have the right   
     to set off any such refunds against amounts due on any invoices         
     received by Laclede under the Agreement in the event VNG violates the   
     Agreement, ceases to be engaged in the natural gas marketing business,  
     is placed into a judicially administered receivership, files for        
     bankruptcy, or is determined to be bankrupt by a Court of competent     
     jurisdiction at any time before the invoice for October, 1996 becomes   
     due and payable.

     d)  Amend paragraph 1 to reflect Laclede's agreement to pay VNG 2.0     
     cents per MMBtu in addition to the charges set forth in such            
     paragraph.  The additional fee shall become effective November 1,       
     1994.  Such additional charges shall not be included in the             
     calculation and comparison of costs required by Article VI, paragraph   
     3, but will be included in VNG's monthly invoice to Laclede.

     e)  Amend paragraph 6 to provide that in the event the parties are,     
     for any reason whatsoever, unable to agree on price redetermination     
     within the period specified therein, Laclede shall have no further      
     purchase or transportation obligations under the Agreement on or after  
     November 1, 1996, and VNG shall have no further sales or                
     transportation obligations to Laclede under the Agreement on or after   
     November 1, 1996.

     4.  VNG commits to Laclede: (a) that VNG's firm transportation on       
     Missouri Pipeline Company through October 31, 1996 is to be provided    
     at rates no greater than those reflected in the tariffs filed with the  
     Missouri Public Service Commission as of November 1, 1994; and (b)      
     that through October 31, 1996, VNG's transportation service on          
     Panhandle Eastern Pipe Line Company ("PEPL") is to be provided under    
     PEPL's Rate Schedule EFT.  During such time, Laclede's charges for      
     base volumes under the Agreement attributable to Panhandle services     
     shall not exceed $7.7 million annually, including surcharges and        
     exclusive of fuel.  If the rates billed VNG by Panhandle result in      
     total charges of less than $7.7 million for base volumes, VNG will      
     reduce the rates billed Laclede to reflect the lower total charges, as  
     required by the existing Agreement.

     5.  Laclede agrees not to seek judicial review of the Missouri Public   
     Service Commission's October 12, 1994 Report and Order in Case No. GM-  
     94-252 if the Closing occurs as provided for in paragraph number 1      
     hereof and the payment of $2,410,000 is received by Laclede in          
     accordance with paragraph 2 hereof.  Until such time as the Closing     
     occurs and the Settlement Payment has been received by Laclede,         
     Laclede may proceed with such filings and/or procedural actions,        
     including administrative rehearing and judicial review, as are          
     necessary to protect its previously asserted legal positions.  In the   
     event such
                                    3 
                                    71                          
   
     filings are made, Laclede agrees to withdraw the same and to seek       
     termination of the proceedings upon receipt of the Settlement           
     Payment.

     6.  This Settlement Letter is a compromise and settlement of all        
     present disputes, claims or causes of action between VNG and Laclede    
     related to the entire Subject Matter.  It is not intended to be, nor    
     shall it be construed as, an admission on the part of either party      
     that its respective interpretations were or are incorrect, or           
     otherwise an admission of liability regarding any dispute, claim or     
     cause of action between them related to the Subject Matter.

     7.  The Agreement shall be amended as specifically set forth in this    
     Settlement Letter.  All other provisions of the Agreement shall remain  
     in full force and effect.

     8.  Laclede, VNG, and their respective successors and assigns, shall    
     be bound by this letter unless and until it is expressly superseded by  
     a more formal amendment to the Agreement, and any provisions of this    
     Settlement Letter not expressly superseded by such formal amendment to  
     the Agreement shall survive.

Please indicate VNG's agreement with the above by signing this letter on the
line below.
