AGREEMENT AND CONVEYANCE OP NET PROFITS INTEREST

THIS AGREEMENT AND CONVEYANCE is by and between MANUFACTURED METHANE
CORPORATION, a Tennessee Corporation, as GRANTOR and HOACTZIN PARTNERS, LP as
GRANTEE. Capitalized terms used but not defined herein shall have the meaning
ascribed to them under that certain Kansas Ten Well Drilling Program of even
date herewith.

In consideration of Grantee's subscription for interests in that certain Kansas
Ten Well Drilling Program conveyed by the Company as of the date hereof ( the
"Drilling Program") and other good and valuable consideration and the further
consideration of the mutual promises and agreements contained herein, Grantor
hereby grants, sells, and conveys to Grantee a "Net Profits Interest" which
shall consist of an interest equal to seventy five percent (75%) of the Net
Profits (defined below) received by Grantor from that certain methane extraction
project at the Carter Valley landfill owned by Allied Waste Industries in Church
Hill, Hawkins County, Tennessee in which Grantor is engaged and has contracted
with the landfill owner for the construction of facilities necessary for
extraction of merchantable methane gas as a substitute for natural gas (the
"Project"). The interest conveyed hereby shall be due and payable monthly by
Grantor to Grantee in cash, commencing upon commercial operations of the Project
and shall continue for the remaining life of the Project; provided, however that
Grantee's Net Profits Interest shall be reduced to seven and one half percent
(7.5%) of the Net Profits received by Grantor at such time that the sum of (i)
the net revenues from. all drilled Program Wells (net of both operating expenses
and management fees) received by Grantee under the Drilling Program and (ii)
receipts from the Grantee's Net Profits Interest exceeds the sum of (i) one
hundred thirty five and 47 hundredths percent (135.47%) of the Purchase Price of
the Units purclmsed by Grantee under the Drilling Program and (ii) the amount of
any further funding provided by Grantee for operating or capital expenses,
plugging and abandonment costs, or in any other respect in relation to the
Program Wells or the Project. For purposes of the calculation set forth in this
paragraph, Grantor shall maintain a reasonable reserve for reasonably
foreseeable future expenses related to the Project. Grantor does not become a
party to, or a third party beneficiary of, any of such other agreements by the
operation of this provision.

In connection with the conveyance made herein as described above, the parties
agree as follows:

1. "Net Profits" shall mean the gross sales price received by Grantor for all
volumes of methane gas actually produced and sold by Grantor from the Project,
less the royalty paid by Grantor to the property owner, less the expenses
incurred by Grantor in operating the mechanical equipment required at the
Project (but excluding capital expenditures) and all associated out of pocket
costs or expenses including: utilities; maintenance; salaries of persons
required for Project operation (excluding however any allocation of general
corporate overhead or salaries); gas analysis or quality testing costs charged
by third parties for Project gas or project facilities such as pipe
metallurgical testing if any; property taxes

whether real or personal assessed to the Project by any taxing authority; and
sales taxes if any are applicable. For the determination of Net Profits of the
Project, any taxes assessed against the pipeline system of Tengasco Pipeline
Corporation or pipeline tariffs charged by Tengasco Pipeline Corporation for
transportation of Project gas shall not be deducted from gas sales proceeds in
determining the Net Profits conveyed hereby,
