complete list and brief description of all material agreements, contracts, 
instruments, licenses, permits and franchises, including all amendments 
thereto relating to Brea, the Partnership or the Facility, or to which 
Brea, the Partnership or the Facility is subject (collectively, the 
"Project Documents").  A true, correct and complete copy of each of the 
Project Documents including all amendments, supplements, exhibits and 
schedules, if any, thereto has been delivered to the Buyer.

          5.13.2  Neither the Power Purchase Agreement nor the Gas

contract, instrument or other similar document (including the Power 
Purchase Agreement and the Gas Agreement) (a) has been duly authorized, 
executed and delivered by the Seller, Brea and/or the Partnership, as the 
case may be, and to the Seller's knowledge, by each of the other parties

terms, is in full force and effect, and (c) to the Seller's knowledge, is a 
valid obligation of such other parties enforceable in accordance with its 
terms, except as may be limited by applicable bankruptcy, insolvency, 
reorganization, moratorium or other laws of general application referring 
to or affecting enforcement of creditor's rights and general principles of 
equity.

          5.13.4  No Default or Event of Default on the part of Brea or the 
Partnership has occurred and is continuing under any Project Document 
(including the Power Purchase Agreement or Gas Agreement), and neither 
Seller, Brea nor the Partnership has received notice, oral or written, that 
a Default or Event of Default on the part of any other Person has occurred 
thereunder or that any Person has alleged or asserted any such Default or 
Event of Default by an Person.

     5.14  No Employees, Etc.  Neither Brea nor the Partnership has any 
employees, or any compensation, bonus, health, sick pay, disability, 
vacation pay, group-term life insurance, dependant care assistance, 
accidental death and dismemberment insurance, severance, employee welfare,

the material Governmental Approvals which are necessary or appropriate in 
connection with the ownership, use, operation and maintenance of the 
Facility and the conduct of Brea's and the Partnership's business and 
activities.  To the Seller's knowledge, except as set forth on Schedule 
5.15, each Permit has been duly and validly issued, or transferred, to Brea 
or the Partnership, as the case may be, and is in full force and effect, 
and all rights and entitlements thereunder are vested exclusively in Brea 
or the Partnership.  Neither the Seller, Brea nor the Partnership has 
received any notice that Brea or the Partnership has committed any act or 
failed to act in any manner or under any circumstances which could result 
in the revocation or suspension of any Permit or in any other disciplinary 
action relating thereto.  The consummation of the transactions provided for 
in this Agreement and the other Closing Documents will not violate any of 
the terms or provisions of the Permits or impose any material obligation on 
the Partnership or Brea.  Neither Seller, Brea nor the Partnership has 
reason to believe that any of such Permits will not be renewed upon their 
natural expiration in the ordinary course of business upon compliance with 
normal and customary renewal procedures applicable to the respective 
Permit.

disposal, spill or discharge at or to the Site or its environment, whether 
onto or into the ground, water, air or otherwise, of any petroleum products 
or of any substance considered a hazardous or toxic substance that would

reasonably expected to occur imminently, other than those which (i) are not 
material, (ii) are permitted under all applicable Environmental Laws and

has been taxed as a partnership for federal income tax purposes under

being made by Seller with respect to any adverse effect on such 
classification which is attributable to the activities of Ridgewood Trust 
as a limited partner of the Partnership.  Except as provided on Schedule 
5.23, no Tax Returns have been audited by any federal, state or local 
taxing authorities and no representation as to tax matters are made for the 
period commencing on and continuing after the Closing Date.

an average rate of delivery at least equivalent to Capacity in accordance 
with the provisions of Section 13.2 during such period of Emergency when 
first requested by Edison, following the date of Firm Operation, shall not 
result in a reduction of Capacity payments as provided for in Appendix C.  
However, after said initial request by Edison, whether or not said request 
has been complied with by Customer, any failure by Customer to comply with 
a subsequent request by Edison shall result in a reduction of Capacity 
payments pursuant to Appendix C. 
     13.4     Periodic Demonstration:  Whether or not Customer has failed 
to respond to an Edison request for delivery of Energy at a rate equivalent 
to Capacity, Edison shall have the right to require a demonstration of the

     APPENDIX B

     ENERGY PURCHASE PROVISIONS

A.     PURCHASE OF ENERGY
     Customer agrees to sell to Edison, and Edison agrees to purchase from 
Customer, the Energy produced by Customer Project and delivered to Edison.  
The monthly Energy payment shall be calculated pursuant to the provisions 
of this Appendix B.
B.     DEFINITIONS
     B.1     Avoided Fuels:  Fuel or fuels that Edison would have otherwise 
used if it had not made purchases of Energy from Customer, but instead 
generated an equivalent amount of energy itself.
     B.2     Discount Factor:  This shall be 1.0 for the first five (5) 
years from the date of initial Energy delivered pursuant to Section 12.1.  
For the balance of the term of this Agreement, the discount factor shall be 
0.87.
     B.3     Edison's Average Boiler Fuel Oil Cost:  The average purchase 
cost shall be determined by averaging Edison's cost in dollars per million 
Btu's for the boiler fuel oil purchased during the previous three (3) month 
period.
     B.4     Edison's Average Natural Gas Cost:  The average purchase cost 
shall be determined by averaging Edison's cost in dollars per million Btu's 
for the natural gas purchased during the previous three (3) month period.
     B.5     Energy:  Net kilowatthours generated by Customer's Generating 
Facility which are purchased by Edison at the Point of Interconnection.

<PAGE>

     B.6     Heat Rate:  The average value, expressed in Btu's per net kWh, 
calculated for the Avoided Fuel during each Time Period.
     B.7     kWh's Delivered to Edison:  The metered value of Energy 
transmitted to Edison by Customer during each Time Period.
     B.8     System Average Cost:  Edison's cost for power as reported to 
the Commission and determined by dividing Edison's recorded costs of fuel 
used and purchased power for each calendar month by energy generated by 
Edison (in kWh) during said month, with adjustment for losses incurred by 
the transmission of electric energy from the generation source to the load.
     B.9     Transmission Factor:  The average value calculated and filed 
with the Commission to compensate (Customer) for losses incurred by the 
transmission of electric energy from the generation source to the load.
C.     ENERGY PAYMENT
     The monthly Energy payment shall be the sum of the payments for the 
on-peak, mid- peak and off-peak Time Periods as calculated pursuant to 
Paragraphs C.1 and C.2.
     C.1     The monthly Energy payment shall be calculated as follows:
               MONTHLY ENERGY PAYMENT =
                         On-Peak Period Energy Payment
                    +      Mid-Peak Period Energy Payment
                    -      Off-Peak Period Energy Payment
     C.2     Energy Payment Calculation

<PAGE>

          The Time Period Energy payment shall be based on Edison's Average 
Boiler Fuel Oil Cost and/or Edison's Average Natural Gas Cost during hours 
when boiler fuel oil and/or natural gas is avoided.  If a fuel other than 
boiler fuel oil or natural gas is avoided, the Time Period Energy Payment 
shall be based on Edison's System Average Cost.
          TIME PERIOD ENERGY PAYMENT =
          [(kWh's Delivered to Edison by Time Period)
          x       (Hours Boiler Fuel Oil is Avoided by Time Period)
               Time Period Hours)*
          x       (Discount Factor)
          x       (Edison's Boiler Fuel Oil Heat Rate by Time Period)
          x       (Edison's Average Boiler Fuel Oil Cost)
          x       (Transmission Loss Factor by Time Period)]
                              +
          x       [(kWh's Delivered to Edison by Time Period)
          x       (Hours Natural Gas is Avoided by Time Period)
               Time Period Hours)*

          x       (Discount Factor)
          x       (Edison's Natural Gas Heat Rate by Time Period)
          x       (Edison's Average Natural Gas Cost)
          x       (Transmission Loss Factor by Time Period)]
     +
               [(kWh's Delivered to Edison by Time Period)

     (Time Period Hours)*

          x       (Edison's System Average Cost)]
          *Time Period Hours are defined in Edison's Tariff Schedule TOU-8.
     C.3     If the monthly Energy payment in Paragraph C.1 for any monthly 
billing period would result in an average payment which is less than 
5.8>/kWh, then the Energy payment shall be based on 5.8>/kWh for those 
kWh's delivered to Edison.

<PAGE>

     APPENDIX C
     CAPACITY PAYMENT PROVISIONS
A.     PURCHASE OF CAPACITY:
     Customer agrees to sell to Edison and Edison agrees to purchase from 
Customer Capacity provided to Edison.  The Capacity payment shall be 
calculated pursuant to the provisions of this Appendix.
B.     DEFINITIONS:
     B.1     Annual Capacity Payment is based on Edison's published Annual 
Capacity Payment Schedule for Firm Power Purchase as filed with and 
approved by the Commission.  This payment shall be $133/kW-year for a 
minimum term of twenty (20) years commencing in 1984.
     B.2     Conversions to Monthly Time Period Payments convert the Annual 
Capacity Payment to a monthly Time Period payment and weighs the value of 
Capacity based on seasonal periods.  These factors are adjusted 
periodically to reflect the value of Capacity delivered during each season 
and Time Period.  The adjustment does not alter the total value of the 
Annual Capacity Payment.
     B.3     Time Period Capacity Factor shall be calculated as follows:
          TIME PERIOD CAPACITY FACTOR (cannot exceed 1) =
                    kWh purchased by Edison
                                                      
               (Capacity expressed in kW) x (No. of hours)*
          *See Credits provided in Paragraph B.3.1.

<PAGE>

          B.3.1     "No. of hours" refers to the total number of hours in 
each Time Period in a specific monthly billing period less the following 
adjustments: (a) Up to a maximum of 480 hours per year due to the 
Generating Facility scheduled maintenance pursuant to Section 8 and the 
disconnection from the Edison electric system pursuant to Section 6, during 
the Time Period in which it occurs, and (b) up to an additional 1080 
consecutive hours for major overhauls at a frequency no more than once 
every three years.
          B.3.2     In the event the number of hours in the aforementioned 
adjustments equal the number of hours in the Time Period, the Period 
Capacity Factor shall be 1.0.
     B.4     Hurdle Factor shall be 1 if the Period Capacity Factor 
calculation is greater than 0.51.  If the Period Capacity Factor is less 
than 0.51, the Hurdle Factor shall be 0.5.
     B.5     Availability Factor shall equal 1 unless Customer fails to 
respond to Capacity request pursuant to Section 13.2.  If Customer fails to 
respond, the Availability Factor shall be 0.5 for either (a) the six (6) 
months following said request and until Customer demonstrates the ability 
to deliver Capacity pursuant to Section 13.5, or (b) until Customer 
complies with a subsequent Emergency request.  If Customer fails to comply 
with a subsequent Edison Emergency request during an existing six (6) month 
period, the reduced Availability Factor shall continue for six (6) months 
following said latest failure, subject to the terms and conditions of the 
preceding sentence.  In all cases the reduced Availability 

<PAGE>

Factor shall apply for the month(s) that Customer failed to respond to a 
Capacity request.  If Customer has notified Edison of a scheduled outage or 
reduction of Capacity availability pursuant to Section 8.5, the reduced 
Availability Factor shall not apply.
C.     CAPACITY PAYMENT
     Capacity shall be calculated as the sum of the on-peak, mid-peak and 
off-peak period Capacity payments.
     C.1     The monthly Capacity payment shall be calculated as follows:
          MONTHLY CAPACITY PAYMENT =
                    On-Peak Period Capacity Payment
               +     Mid-Peak Period Capacity Payment
               +      Off-Peak Period Capacity Payment
     C.2     The Time Period Capacity payments shall be calculated as 
follows:
          CAPACITY PAYMENT =
                    (Annual Capacity Payment)
               x     (Conversion to Monthly Time Period Payment)
               x     (Capacity)
               x     (Time Period Capacity Factor)
               x     (Hurdle Factor by Time Period)
               x     (Availability Factor)
D.     EXAMPLE

<PAGE>

     For example, as of December 1982, the summer monthly Capacity payment 
would be calculated as the sum of the following Time Period Capacity 
payments:
          SUMMER:
               On-Peak  =     $133  x  .13125  x  4900  kW  x  0.9  x  1  x  
1
               Mid-Peak =     $133  x  .00267  x  4900  kW  x  0.9  x  1  x  
1
               Off-Peak  =     $133  x  .00000  x  4900  kW  x  0.9  x  1  
x  1
     NOTE:      The above example assumes Hurdle, Availability Factors of 1 
and Period Capacity Factors of 0.9.

<PAGE>

     APPENDIX D
     PROCEDURE FOR ENERGY AND CAPACITY PAYMENT
The method by which Customer is paid for Energy and Capacity is based on 
the following:
1.     Edison shall determine from monthly meter readings the Energy and 
Capacity purchased by Edison during the various Time Periods for the 
preceding monthly billing period.
2.     Edison shall calculate the amount owed Customer for Energy and 
Capacity purchased in accordance with Appendix B and Appendix C.
3.     If the monthly billing period involves portions of two different 
published Energy payment schedule periods, the monthly Energy payment shall 
be prorated on the basis of the percentage of days at each price.
4.     Within twenty (20) days following each monthly meter reading Edison 
shall request a cash voucher in order to initiate payment to Customer and 
mail a statement to Customer indicating the amount of Energy and Capacity 
purchased during the billing period and the amount to be paid.  If within 
thirty (30) days of receipt of the statement, Customer does not report, in 
writing, to Edison of an error, then the payment will be considered correct 
and complete.
5.     Edison shall prepare and mail check to Customer within ten (10) days 
of mailing of the statement.

SPECIAL CONDITIONS (Continued)

     3.     Maximum Demand:  Maximum demands shall be established for the 
on-peak, mid-peak, and off-peak periods.  The maximum demand for each 
period shall be the measured maximum average kilowatt input indicated or 
recorded by instruments to be supplied by the Company, during any 15-minute 
metered interval, but (except for new customers or existing customers 
electing Contract Demand as defined in these Special Conditions) not less 
than the diversified resistance welder load computer in accordance with the 
section designated Welder Service in Rule No. 2.  Where the demand is 
intermittent or subject to violent fluctuations, a 5-minute interval may be 
used. 

     4.     Billing Demand:  Separate billing demands for the on-peak, mid-
peak, and off-peak time periods shall be established for each monthly 
billing period.  The billing demand for each time period shall be the 
maximum demand for that time period occurring during the respective monthly 
billing period. 

     5.     Contract Demand:  A contract demand will be established by the 
Company, based on applicant's demand requirements for any customer newly 
requesting service on this schedule and for any customer of record on this 
schedule who requests an increase or decrease in transformer capacity in 
accordance with Rule No. 22 D.  A contract demand arrangement is available 
upon request for all customers of record on this schedule.  The contract 
demand will be used only for purposes of establishing the minimum demand 
charge for facilities required to provide service under the rate and will 
not be otherwise used for billing purposes.  Contract demand is based upon 
the nominal kilowatt-ampere rating of the Company's serving transformer(s) 
or the standard transformer size determined by the Company as required to 
serve the Customer's stated measurable kilowatt demand, whichever is less 
and is expressed in kilowatts. 

     6.     Minimum Demand Charge:  Where no contract demand is involved, 
the monthly minimum demand charge shall be not less than the charge for 25% 
of the maximum on-peak demand established during the preceding 11 months.  
Where a contract demand is involved, the monthly minimum demand charge 
shall be the greater of:  

          a.     The charge as computed by multiplying 25% of the maximum 
on-peak demand, established during the preceding 11 months by the demand 
charge per kilowatt; or 

          b.     A facilities charge of $1.00 per kW of contract demand. 

     7.     Excess Transformer Capacity.  The customer capacity in excess 
of a customer's contract demand which is either required by the Company 
because of the nature of the customer's load or requested by the customer.  
Excess transformer capacity shall be billed at $1.00 per kVA per month. 

     8.     Voltage Discount:  The charges before adjustments will be 
reduced by 3% for service delivered and metered at voltages of from 2kV to 
10kV; by 4% for service delivered and metered at voltages of from 11 kV to 
50kV; and by 5% for service delivered and metered at voltages over 50 kV; 
except that when only one transformation from a transmission voltage level 
is involved, a customer normally entitled to a  3% discount will be 
entitled to a  4% discount.  

     9.     Power Factor Adjustment: 

          a.     Service Delivered and metered at 4 kV or Greater: 
               The charges will be adjusted each month for reactive demand.  
The charges will be increased by 20 cents per kilowatt of maximum reactive 
demand imposed on the Company in excess of 20% of the maximum number of 
kilowatts. 

               The maximum reactive demand shall be the highest measured 
maximum average kilovar demand indicated or recorded by metering to be 
applied by the Company during any 15-minute metered interval in the month.  
The kilovars shall be determined to the nearest unit.  A device will be 
installed on each kilovar meter to prevent reverse operation of the meter. 

          b.     Service Delivered and Metered at Less than 4 kV: 
               The charges will be adjusted each month for the power factor 
as follows:  
               The charges will be decreased by 20 cents per kilowatt of 
measured maximum demand and will be increased by 20 cents per kilovar of 
reactive demand.  However, in no case shall the kilovars used for the 
adjustment be less than one-fifth the number of kilowatts. 
               The kilovars of reactive demand shall be calculated by 
multiplying the kilowatts of measured maximum demand by the ratio of the 
kilovar-hours to the kilowatthours.  Demands in kilowatts and kilovars 
shall be determined to the nearest unit.  A ratchet device will be 
installed on the kilovar-hour meter to prevent its reverse operation on 
leading power factors.

BOARD OF SUPERVISORS
ORANGE COUNTY, CALIFORNIA          MINUTES      December 14, 1993



PUBLIC HEARING -- AMENDED AND RESTATED GAS LEASE AGREEMENT WITH GSF ENERGY, 
INC. FOR OLINDA/OLINDA ALPHA LANDFILL:  Integrated Waste Management 
Department requests approval of an amended and restated gas lease agreement 
for development of the landfill gas rights and landfill gas utilization 
systems at the Olinda/Olinda Alpha Landfill.

Supervisor Vasquez commented that the amendment provides for the 
construction of a flare to comply with regulations and to protect public 
health and safety.  Also, the amendment extends the lease to match the 
terms of GSF's agreement with Southern California Edison and gives GSF 
additional incentives to sell electricity generated by its gas collection 
system.

Chairman Wieder opened the public hearing and asked if anyone wished to 
address the board on the matter.  Hearing no response, she declared the 
public hearing closed.

Supervisor Vasquez pointed out that the County was receiving in excess of 
$350,000 a year in royalties from the project, and that the amendment and 
restated gas lease agreement would help to ensure future proceeds.

MOTION:  On motion by Supervisor Vasquez, seconded by Supervisor Riley, the 
Board moved to:  1.  Find that the construction of the flare facility is 
categorically exempt, Class 1(f) and 29, from the provisions of the 
California Environmental Quality Act.  2.  Find that:  (a) the anticipated 
cost to the County for electrical energy provided by the energy 
conservation facility under the proposed Amended and Restated Gas Lease 
Agreement will be less than the anticipated marginal cost to the County of 
electrical energy that would have been consumed by the county in the 
absence of those purchases, and (b) the difference, if any, between the 
fair rental value of the real property subject to the facility ground lease 
and the agreed rent, is anticipated to offset by below-market energy 
purchases or other benefits provided under the Amended and Restated Gas 
Lease Agreement.  3.  Authorize execution of the Amended and Restated Gas 
Lease Agreement with GSF Energy, Inc., to: (a) construct the flare facility 
for the County, and (b) pursue construction of additional electrical 
generation capacity if GSF Energy, Inc. is successful in its bid to 
Southern California Edison.  MOTION UNANIMOUSLY CARRIED.

                          GAS LEASE AGREEMENT


THIS AMENDED AND RESTATED GAS LEASE AGREEMENT is made December 14, 1993, by 
and between the COUNTY OF ORANGE, a political subdivision of the state of 
California, hereinafter referred to as "LESSOR" and GSF ENERGY INC., a 
Delaware corporation (successor in interest to Getty Synthetic Fuels, Inc.) 
hereinafter referred as "LESSEE".

RECITALS

I.     LESSOR and LESSEE entered into a Gas Lease Agreement ("Original 
Lease") dated for reference February 12, 1981, granting LESSEE the right to 
the Refuse Gas and/or Constituent Products produced and recovered from 
LESSOR's Olinda Canyon portion of the Landfill.  

II.     LESSOR and LESSEE entered into a First Amendment to Gas Lease 
Agreement ("First Amendment") on May 2, 1989, which extended the scope of 
the Lease interest to include the Alpha Canyon portion of the Landfill on 
an interim basis.

III.     LESSOR and LESSEE entered into a Second Amendment to the Gas Lease 
Agreement ("Second Amendment") on March 30, 1993, which extended the term 
of the Original Lease and provided for certain modifications and 
maintenance work to be performed thereunder with respect to the Alpha 
Canyon Refuse Gas Collection System.

IV.     LESSOR is the owner and operator of the municipal solid waste 
Landfill and is required by various regulatory entities to control 
migration and emission of Refuse Gas produced by the decomposition of 
refuse within the Landfill.  LESSOR desires to expand the current Refuse 
Gas Collection System so as to meet regulatory requirements and utilize the 
energy potential of the Refuse Gas in a more efficient manner than would 
result if the Refuse Gas were simply flared.

V.     LESSOR and LESSEE now desire to further amend the Original Lease as 
amended by the First Amendment and the Second Amendment ("Amended Lease") 
in order to create an integrated Refuse Gas recovery program at the 
Landfill that will more efficiently utilize the energy potential of the 
Refuse Gas and will also include a Refuse Gas Flare Facility required to 
comply with regulations and to protect public health and safety.  

NOW, THEREFORE, in consideration of the mutual covenants and agreements 
hereinafter contained, LESSOR and LESSEE, intending to be legally bound, do 
mutually agree that, effective as of the date written above, the Lease 
shall be further amended and restated, and this Amended and Restated Gas 
Lease Agreement (the "Lease") shall supersede and replace all prior

expected to exceed two and one half (2 1/2) acres.


3.     Term.

     3.1  Term.  This Lease shall become effective upon the date first 
above written and shall continue for a primary period ending on January 1, 
2005, and thereafter for succeeding periods of one (1) year each, 
terminable upon written notice by either party to the other not less than 
ninety (90) days before the end of the primary period or before the end of 
any succeeding yearly period.

     3.2  Term Extension.  Southern California Edison is currently 
soliciting bids pursuant to Final Standard Offer 4 as contemplated by 
Section 6.2.  In the event that LESSEE is successful in negotiating and 
entering into a contract with Southern California Edison pursuant to said 
Final Standard Offer 4 or in obtaining a suitable alternative purchaser, 
the Director shall extend the term of this Agreement to coincide with the 
term of the purchase agreement.  In no event shall the extended term exceed 
the term of such contract between Southern California Edison or other 
purchaser and LESSEE.

4.     Revenues

     4.1  Royalty Payments.  LESSEE hereby agrees to pay LESSOR a royalty 
equal to twelve and one-half percent (12 1/2%) of the (i) gross proceeds 
(including the fair market value of all goods, products, and/or services 
obtained by LESSEE in lieu of sales revenues) and (ii) entitlement (under 
Title 10 Code of Federal Regulation Section 211.67 as may be amended or 
superseded) received solely from the sale of all processed Refuse Gas 
and/or Constituent Products produced by the Landfill or energy derived 
therefrom (including, by way of illustration and not limitation, electrical 
generation), less property taxes, less casinghead gas or natural gas 
purchases, and less tax obligations, if any, described in Sections 19.1 or 
19.2 below.  The royalty shall be paid to LESSOR on or before the last day 
of each month based on the previous month's sales.

     4.2  Charge for Late Payment.  LESSEE hereby acknowledges that the 
late payment of rent or royalties will cause LESSOR to incur costs not 
contemplated by this Lease, the exact amount of which will be extremely 
difficult to ascertain. Such costs include but are not limited to costs 
such as administrative processing of delinquent notices and increased 
accounting costs.  Accordingly, if any payment of royalty as specified in 
Section 4.1, is not received by LESSOR or postmarked within ten (10) days 
after the due date, a late charge of one (1%) of the payment due and unpaid 
plus twenty-five dollars ($25) shall be added for the payment, and the 
total sum shall become immediately due and payable to LESSOR.  An 
additional charge of one percent (1%) of said payment, excluding late 
charges, shall be added to each additional month that said payment remains 
unpaid.  LESSEE and LESSOR hereby agree that such late charges represent a 

<PAGE>

fair and reasonable estimate of the costs that LESSOR will incur by reason 
of LESSEE's late payment.  Acceptance of such late charges (and/or any 
portion of the overdue payment) by LESSOR shall in no event constitute a 
waiver of LESSEE's default with respect to such overdue payment, nor 
prevent LESSOR from exercising any of the other rights and remedies granted 
hereunder.

     4.3   Records and Financial Statements.

     (a)     Records.

          LESSEE shall, at all times during the term hereof, keep or cause 
to be kept true and complete books, records, and accounts, together with 
applicable supporting documentation, of all financial sales transactions in 
connection with the Project and LESSEE's operations hereunder.  LESSOR 
shall have the right through an independent certified public accounting 
firm or otherwise through duly authorized and similarly qualified 
agents/representatives, to examine and audit said books, records, and 
accounts, upon thirty (30) days advance written notice to LESSEE, during 
normal business hours at LESSEE's place of business. Such inspections shall 
relate to the operations of LESSEE during any Accounting year and shall be 
conducted within a sixty (60) month period following the end of said 
Accounting Year.

     (b)     Discrepancies.

          Full cost of any audit conducted under Section 4.3(a) shall be 
borne by LESSEE if the audit reveals either (i) a discrepancy in the amount 
of royalty payments due LESSOR of greater than two percent (2%), or (ii) 
LESSEE has failed to maintain true and complete books, records, accounts 
and/or supportive source documents as required by Section 4.3(a) hereof.  
Otherwise, LESSOR shall bear the cost of said audit.

     (c)     Financial Statements.

          Within ninety (90) days after the end of each Accounting Year, 
LESSEE shall, at LESSEE's expense, submit to LESSOR a statement, certified 
as to accuracy by a Certified Public Accountant or a similarly qualified 
corporate accountant/auditor employed by LESSEE or an affiliate, wherein 
the total gross proceeds and entitlements, and amounts permitted to be 
offset therefrom, for such Accounting Year are set forth and categorized 
according to the Royalty classification set forth in the above Section 4.1.  
Moreover, LESSEE shall make available to LESSOR, upon request, necessary 
base data to assist LESSOR in complying with requirements of the State of 
California or the United States of America or any governing body for 
information relating to LESSEE's operations under the Lease.

<PAGE>

     4.4  Used/Consumed/Lost Gas Products.  Nothing contained herein shall 
be deemed to obligate LESSEE to account to LESSOR for, or pay a royalty on, 
any Refuse Gas and/or Constituent Products which are actually and 
reasonably used, consumed or lost in LESSEE's operations hereunder; 
provided, however, should LESSEE so alter its recovery and processing 
system to cause a significant increase in usage, LESSEE, upon LESSOR's 
written request, shall prepare and furnish LESSOR with an accounting of 
such usage to verify its reasonableness.

     4.5  Use of Excess Gas.  LESSOR shall have the right to take or 
otherwise use Excess Gas for energy recovery purposes with the approval of 
LESSEE.  Such approval shall not be unreasonably withheld.  Excess Gas 
shall be recovered in such a manner so as not to negatively impact LESSEE's 
energy recovery operations.  In the event the recovery of such Excess Gas 
is required to comply with any applicable public laws, including federal, 
state, and local statutes and regulations and any order of a regulatory 
agency or authority, LESSOR and LESSEE agree to work together to develop 
Refuse Gas Collection System additions, operational methods, and techniques 
in order for LESSOR to meet applicable public law.  In the event LESSOR and 
LESSEE cannot agree on such remediation approach, LESSOR maintains its 
right to proceed with such action.

5.     Testing and Evaluation Program.

     5.1  Testing and Evaluation.  LESSEE shall conduct such tests as it 
deems appropriate in order to determine whether Refuse Gas and/or 
Constituent Products can economically be recovered from the Landfill in 
Commercial Quantities.  LESSEE, at its sole expense, will commence testing 
and evaluation of the Landfill for Refuse Gas and/or Constituent Products 
and complete a technical and economic feasibility study in accordance with 
the New Project Schedule.  A copy of said feasibility study will be 
provided LESSOR upon completion, with materials deemed proprietary by 
LESSEE deleted, or at LESSOR's option, with such materials included subject 
to the prior execution by LESSOR of a suitable confidentiality agreement.

     5.2  Reversion.  In the event that LESSEE has not entered into a 
binding agreement with a suitable purchaser for additional Refuse Gas 
and/or Constituent Products on terms and conditions satisfactory to LESSEE 
by January 31, 1995, LESSOR shall have the right to terminate LESSEE's 
right to collect and process Refuse Gas from the Alpha Canyon portion of 
the Landfill by deleting the description of Alpha Canyon from Exhibit "I" 
upon thirty (30) days advance written notice given by the Director.  It is 
expressly understood that if the right of LESSEE to collect gas from Alpha 
Canyon portion of the Landfill is terminated, LESSEE shall have no further 
operating or maintenance obligations for the Refuse Gas Collection System 
in the Alpha Canyon portion of the Landfill.  In the event of LESSOR's 
termination of LESSEE's right to collect and process Refuse Gas from the 
Alpha Canyon portion, all other terms and conditions of the Lease shall 
remain in full force and effect.

     5.3  Commercial Recovery.  Should LESSEE determine in its sole 
judgment, following completion of its testing and evaluation program, that 
the results of said testing and evaluation program indicate the Landfill is 
suitable for the economic recovery and processing of Refuse Gas 

<PAGE>

and/or Constituent Products in Commercial Quantities as the New Project, 
LESSEE shall provide LESSOR with written notice of such judgment in 
accordance with the "Go/No Go" decision as specified in the New Project 
Schedule, and this Lease shall continue in effect.

6.     Operations.

     6.1  Security for Construction of Facilities.  Upon notice of an 
election under Section 5.3 hereof to proceed, LESSEE shall furnish LESSOR 
(i) a Performance Bond or equivalent Letter of Credit in the amount of one 
hundred thousand dollars ($100,000) for the faithful performance of the 
construction of New Project plant and related Refuse Gas Collection System 
provided herein, and (ii) a simultaneously issued Labor and Material 
Payment Bond or equivalent Letter of Credit, in the amount of fifty percent 
(50%) of said Performance Bond, with respect to said construction.  Such 
bonds or letters of credit shall be forfeited in form and shall terminate 
or shall be drawn upon nine (9) months subsequent to the later of June 1, 
1997, or the completion of said construction.  

Within sixty (60) days after receipt of the permit to construct the Flare 
Facility, LESSEE shall furnish LESSOR (i) a Performance Bond or equivalent 
Letter of Credit in the amount of eight hundred ninety five thousand and 
one hundred dollars ($895,100) for the faithful performance of the 
construction of the Flare Facility, and (ii) a simultaneously issued Labor 
and Material Payment Bond or equivalent Letter of Credit, in the amount of 
fifty percent (50%) of said Performance Bond, with respect to said 
construction.  Such bonds or letters of credit shall be forfeited in form 
and shall terminate or shall be drawn upon nine (9) months subsequent to 
the later of January 31, 1995, or the completion of said construction.

     6.2  Construction of Facilities.  In order to maximize gross proceeds 
and LESSOR's resulting royalty revenues and LESSOR's other associated 
benefits under this Lease, LESSEE is interested in pursuing opportunities 
to increase the capacity of its energy recovery activities at the Landfill 
through the New Project and has submitted a bid to Southern California 
Edison on November 9, 1993.  Subject to LESSEE's confirmation that the 
Landfill can support sufficient additional energy recovery capacity over a 
term commercially attractive to LESSEE, to the giving of notice pursuant to 
Section 5.3 above, to the attainment of a suitable purchaser for additional 
Refuse Gas and/or Constituent Products on terms and conditions satisfactory 
to LESSEE, and to LESSEE's entering into a binding agreement with such 
purchaser for the purchase of such additional Refuse Gas and/or Constituent 
Products, (a) LESSOR and LESSEE shall extend the lease as provided in 
Section 3 (Term) above; and (b) LESSEE shall, at its sole expense, commence 
the engineering, design, procurement of requisite governmental 
authorization, and construction of necessary additional facilities for 
collecting and processing increased quantities of Refuse Gas and/or 
Constituent Products in accordance with the project schedule set forth in 
the binding agreement with such purchaser for the purchase of additional 
Refuse Gas and/or Constituent Products.  After completion of the 
construction and required break-in of these additional facilities, LESSEE 
will collect, process, and sell the additional Refuse Gas and/or 
Constituent Products obtained from the Landfill in accordance with the 
terms of the Lease.

<PAGE>

     6.3  Status Reports and Plant Completion.  LESSEE will provide to 
LESSOR written monthly status reports on LESSEE's progress with respect to 
the New Project Schedule and Flare Facility project schedule.  Subject to 
the provisions of Section 11 and Section 13.1 hereof, if LESSEE fails to 
complete said work in accordance with the New Project Schedule or Flare 
Facility project schedule within such time, and if LESSEE has not cured or 
substantially cured such failure within the time period specified in 
Section 13.1, LESSOR may, by written notice to LESSEE, terminate LESSEE's 
right to proceed with the work or such part of the work as to which there 
has been delay.  In such event, LESSOR may take over the work and pursue 
the same to completion, by contract or otherwise, and in order to 
effectuate said completion, LESSEE shall, insofar as its right to proceed 
is terminated, promptly surrender to LESSOR all completed work and work-in-
progress, and all non-proprietary materials, records, and notes procured 
and/or produced pursuant to the Lease.

     6.4  Use of Gas/Products.  Subject to Section 4.4 hereof, LESSEE shall 
have free use of that portion of the Refuse Gas and/or Constituent Products 
produced by the Landfill which is necessary to conduct its operations and 
to market Refuse Gas under this Lease.  Nevertheless, LESSEE shall use its 
best efforts to maximize the efficiency of its operations and marketing 
activities to lessen such use to the extent reasonably practicable.

If LESSOR at any time shall have reason to question the accuracy of any 
gauge or device used in measuring or computing the Refuse Gas (i) used for 
operating LESSEE's facilities, and/or (ii) sold hereunder, LESSOR shall so 
notify LESSEE in writing, and, thereafter, such gauge or device shall be 
tested in the presence of both parties.  Should such tests reveal an 
inaccuracy of two percent (2%) or greater, the quantity shall be 
recalculated and corrected for the period beginning thirty (30) days 
immediately prior to the date of said notice (or beginning on the date such 
inaccuracy commenced, if ascertainable).  If the gauge or device is found 
to be accurate within two percent (2%), then LESSOR shall bear the expense 
of tests made at its request; otherwise, LESSEE will be responsible for the 
costs of such tests.

     6.5  Prudent Operations.  Subject to the provisions of this Lease, 
LESSEE shall test for, collect, treat, process and market the Refuse Gas 
and/or Constituent Products produced by the Landfill as a reasonably 
prudent operator.  In discharging this obligation, LESSEE shall be 
responsible, in its sole discretion, for determining all operational plans 
and details (excepting the placement of wells and collection facilities on 
the Landfill) directly affecting production and processing to ensure a 
workable system having the greatest recovery potential; provided, however, 
that LESSEE shall conduct its testing program, construction activities and 
operations in such a manner so as not to interfere with LESSOR's use and/or 
maintenance of the Landfill, unless LESSOR otherwise consents.

LESSOR shall inform LESSEE of all significant planning, design, expansion, 
and construction meetings concerning any Refuse Gas collection activities.  
LESSOR shall invite LESSEE to attend and provide comments concerning all 
Refuse Gas collection activities at the Landfill.

<PAGE>

As to placement of wells and collection facilities including the Refuse Gas 
Collection System, it is agreed that prior to testing and before 
installation of any equipment or operational facilities in or upon the 
Landfill, LESSEE shall furnish LESSOR with the Refuse Gas collection System 
grid-well layout and development plans attendant thereto.  LESSOR shall 
have fifteen (15) working days from such submittal in which to review such 
plans and advise LESSEE of LESSOR's approval (which shall not be 
unreasonably withheld) or any specific objections, silence being deemed an 
approval.  The parties shall endeavor in good faith to resolve said 
objection(s) within ten (10) working days thereafter, but should the 
parties be unable to resolve such objection(s), LESSOR and LESSEE shall 
mutually designate, within ten (10) working days thereafter, a 
disinterested third person arbitrator who shall, within thirty (30) days 
thereafter, formulate a resolution which will be binding upon LESSOR and 
LESSEE.

It is further understood that LESSEE shall use its best efforts to procure 
the highest sales revenues reasonably obtainable for the Refuse Gas and/or 
Constituent Products produced and marketed from the Landfill.  Although the 
implementation of a gas enhancement or stimulation program is unanticipated 
by the parties with respect to Refuse Gas production, it is agreed that any 
such enhancement type program will be undertaken only with LESSOR's prior 
written consent, such consent shall not be unreasonably withheld.  It is 
understood that the wet-weather area, also known by the parties as the 
third level portion of the Landfill, has not been brought to final grade, 
and the parties hereto agree to cooperate in minimizing the impact of such 
condition on the Project.

     6.6  Return of Landfill Liquids.  LESSEE shall, in connection with its 
activities on the Landfill hereunder, have the right in its sole 
discretion, without cost to LESSEE, to return to the Landfill any and all 
matter either solid or liquid (including condensate) removed from the 
Refuse Gas and/or Constituent Products collected from the Landfill provided 
such return is lawful under applicable federal, state, and local 
governmental authority.

Upon installation by LESSOR of a leachate treatment facility, condensate 
disposal will be provided by LESSOR's leachate treatment facility, at no 
cost to LESSEE.  If LESSOR is not able or willing to dispose of Refuse Gas 
condensate after December 31, 1995, LESSEE shall reduce the royalty payment 
described in Section 4 by LESSEE's direct cost of the Refuse Gas condensate 
disposal.

     6.7  Installation of Refuse Gas Collection System.  LESSEE and LESSOR 
agree to work together to develop operational methods and techniques in 
order to optimize the quality and quantity of gas recovered from LESSOR's 
horizontal gas collectors in the Landfill.  To the extent reasonably 
practicable LESSEE agrees to utilize LESSOR's horizontal gas extraction 
system, vertical gas wells, and header to produce and recover Refuse Gas 
therefrom and transport Refuse Gas therefrom and transport Refuse Gas to 
LESSEE's Olinda electrical generating facilities.

All work required for capital additions (new wells, new collectors, new 
laterals, new headers, and all associated devices) to the Refuse Gas 
Collection System and major maintenance (as 

<PAGE>

described in Exhibit "X") to the Refuse Gas Collection System prior to the 
time the New Project, contemplated by Section 6.2 (Construction of 
Facilities), is placed in service, shall be performed by LESSEE and paid 
for by LESSOR under the terms and conditions of Exhibit "VT".  LESSEE shall 
provide LESSOR with a written cost estimate of such work.  LESSEE shall not 
proceed with this work prior to the approval of LESSOR.  If LESSOR and 
LESSEE cannot agree on such costs, LESSOR maintains its right to obtain 
such work from other sources at LESSOR's option.

After the New Project has been placed into service, LESSEE will pay the 
first $40,000 per year, adjusted annually in accordance with Paragraph 2.9 
(Cost Index), of Refuse Gas Collection System capital additions and major 
maintenance.  All additional work required for capital additions (new 
wells, new collectors, new laterals, new headers, and all associated 
devices) to the Refuse Gas Collection System and major maintenance (as 
described in Exhibit "X") performed on the Refuse Gas Collection System 
after the time the New Project, contemplated by Section 6.2 (Construction 
of Facilities), is placed in service, shall be performed by LESSEE and paid 
for by LESSOR under the terms and conditions of Exhibit "V".  LESSEE shall 
provide LESSOR with a written cost estimate of such work.  LESSEE shall not 
proceed with this work prior to the approval of LESSOR.  If LESSOR and 
LESSEE cannot agree on such costs, LESSOR maintains its right to obtain 
such work from other sources at LESSOR's option.

If LESSEE is not successful in obtaining a Final Standard Offer 4 contract 
with Southern California Edison or in obtaining an acceptable alternative 
energy purchaser, LESSEE will continue to perform capital additions in 
accordance with Exhibits "V" and "VIII" and major maintenance as defined 
herein when requested by LESSOR.

     6.8  Flare Facility Installation and Related Services.  LESSOR has 
proposed, and LESSEE has agreed to certain work and services to be 
performed by LESSEE with respect to a Flare Facility to be installed at the 
Landfill adjacent to LESSEE's existing gas processing facilities, that will 
allow Refuse Gas and condensate to be incinerated reliably over the long-
term (the "Flare Work") as contemplated in Section 6.7 (Installation of 
Refuse Gas Collection System) of the Lease.  Notwithstanding any other 
provisions of the Lease to the contrary, (i) LESSEE has proposed and LESSOR 
has agreed to the particular Flare Facility described in Exhibit "VI" 
attached hereto; (ii) LESSEE shall provide such Flare Facility for a lump 
sum price of one million three hundred thousand dollars ($1,300,000) of 
which one million ninety two thousand six hundred dollars ($1,092,600) 
shall be for the Flare Facility described herein and of which two hundred 
seven thousand four hundred dollars ($207,400) shall be for owner 
enhancements beyond the scope of the Flare Facility design, such 
enhancements to be at the sole discretion of LESSOR and authorized in 
writing by LESSOR; and (iii) LESSOR shall pay for the Flare Facility in 
cash payments to LESSEE payable upon completion of the project schedule 
deliverables indicated in Exhibit "VII".

Following completion of the health risk assessment and Flare Facility 
design and prior to submitting an application for a permit to construct to 
the South Coast Air Quality Management District (SCAQMD), LESSEE shall 
submit the health risk assessment and Flare Facility design to the Director 
of the County Environmental Management Agency (EMA) for review and 

<PAGE>

approval to ensure that the Flare Facility is designed so its operation 
would cause no significant adverse air quality impact.

     6.9  The Flare Facility Operations and Maintenance.  The Flare 
Facility Work will be treated for all purposes under the Lease as, and 
shall become, part of the facilities operated by LESSEE, and owned by 
LESSOR and shall be maintained as described in Exhibit "IX".  
Notwithstanding any other provisions of the Lease to the contrary, LESSEE 
will be responsible for providing Routine Flare Facility Operation and 
Maintenance as defined in Exhibit "IX" at its expense, and LESSOR will 
reimburse LESSEE for the purchase of electrical power, propane, and 
condensate disposal for the Flare Facility.  LESSEE will perform non-
routine operation and maintenance activities on the Flare Facility on 
behalf of LESSOR.  LESSEE shall provide LESSOR, in advance, cost estimates 
pertaining to any non-routine operating and maintenance services for which 
LESSEE will be reimbursed by LESSOR according to the fee schedule described 
in Exhibit "VIII" attached hereto.  If the two parties cannot agree on such 
costs, LESSOR maintains its right to obtain such work from other sources at 
LESSOR's option.  If electrical power is produced for sale by the New 
Project, LESSEE shall provide electrical power to operate the Flare 
Facility when feasible and at no cost to LESSOR, however, LESSOR shall pay 
all charges by Southern California Edison related to Southern California 
Edison's supply of electrical power and/or the services to provide 
electrical power for the Flare Facility.

7.     Title To Facilities, Surrender of Facilities, and Lease.  LESSOR 
shall have title to existing components of the Refuse Gas Collection System 
for which LESSOR has paid the cost of installation.  LESSOR shall have 
title to all future components of the Refuse Gas Collection System and to 
the Flare Facility upon acceptance of said Flare Facility as complete.  
LESSEE shall have title to all other components of the Refuse Gas 
Collection System existing at the time of execution of this Amended and 
Restated Gas Lease Agreement.  LESSEE shall have title to all future 
components of the Project for which LESSEE pays the cost of installation 
and that are not part of the Refuse Gas Collection System subject to terms 
of this Amended and Restated Gas Lease Agreement.  At any time during the 
term hereof that LESSEE determines that the Project and/or New Project, or 
the continuation thereof, is not technically, economically, or practically 
feasible, LESSEE, at its option, may surrender and terminate this Lease 
subject to the following obligations: (i) LESSEE shall have the 
responsibility under Section 9.1 below, at the request of LESSOR, to remove 
above ground property, fixtures, and improvements owned by LESSEE and 
placed on the Landfill; (ii) LESSEE shall provide LESSOR at time of 
surrender with a written explanation of the basis for LESSEE's decision to 
terminate the Lease; (iii) LESSEE shall provide LESSOR with summaries of 
any test results and the results of operation; and (iv) LESSEE shall 
transfer ownership of the Refuse Gas Collection System, owned by LESSEE, 
constructed hereunder, to LESSOR without charge to LESSOR.

8.     Property Rights.

     8.1  Land Use.  LESSEE shall be authorized to use the Landfill, 
including the Alpha Canyon portion, and any adjacent or contiguous land 
owned or controlled by LESSOR without cost except as otherwise provided 
herein, to the extent reasonably necessary or convenient for 

<PAGE>

LESSEE's facilities and operations hereunder, including the construction 
and maintenance of all necessary wells, pipelines, and utility lines, and 
the free right of ingress and egress at all times to and from said 
property; however, the rights herein granted should be exercised by LESSEE 
in a way which shall not unreasonably interfere or be inconsistent with 
LESSOR's ongoing Landfill activities.

     8.2  Plant Site.  LESSOR shall make available to LESSEE if requested 
without cost, immediately adjacent to but not upon the surface of the 
Landfill, a mutually acceptable site sufficient in size to accommodate the 
construction and operation by LESSEE of the gas processing plant(s) and 
related facilities for the Project, and LESSEE shall have the free right of 
ingress and egress at all times to and from said Plant Site.

     8.3  Underground Wells and Pipelines.  All gas collection wells (below 
the wellhead) and gas gathering pipelines shall be placed below the surface 
of the Landfill.  LESSOR shall use its best efforts to avoid damaging 
wellheads necessarily protruding during continuation of landfill 
activities.  Upon completion of said landfill activities, LESSEE shall 
place the wellheads below the surface unless LESSOR otherwise consents.

     8.4  Oil and Gas Rights.  This Lease shall not be deemed to grant to 
LESSEE any rights to or interests in any oil or natural gas located under 
the Landfill which is not produced by the Landfill.

     8.5  Easements.  LESSOR agrees to grant such rights of way and 
easements as may be necessary for the purchaser of the Refuse Gas and/or 
Constituent Products to accept delivery thereof at LESSEE's gas processing 
plant(s).

     8.6  Cooperation in Obtaining Authorization.  Upon reasonable request 
by LESSEE, LESSOR shall make documents available, attend and otherwise 
assist LESSEE in proceedings, hearings, or other procedures necessitated by 
any required environmental impact reports, governmental permits, 
authorizations and similar type requirements, related to the Project and 
the construction and operation of LESSEE's wells, Refuse Gas Collection 
System, and gas processing facilities.  Upon reasonable request of LESSOR, 
LESSEE shall assist LESSOR in briefing the officials of a governmental 
agency or body, or other interested party, with respect to the status of 
the Project.

     8.7  Landscaping.  LESSEE shall, upon written request from LESSOR, be 
obligated to install and maintain such landscaping as may be required for 
adequate screening of the plant site and appurtenant equipment which are 
utilized by LESSEE in its operations hereunder.  LESSOR shall be 
responsible for any landscaping which is located on LESSOR's property 
external to said plant site.

     8.8  LESSOR's Activities.  LESSOR agrees to conduct its Landfill 
activities, and the Landfill activities of its agents, representatives, 
tenants, contractors, or assignees, so as not to unreasonably interfere 
with LESSEE's programs, construction activities, and/or operations 

<PAGE>

hereunder, unless LESSEE otherwise consents, subject to a Letter of Intent 
of February 12, 1981 (a copy of which is attached hereto as Exhibit "III" 
and by reference made a part hereof).

It is understood that LESSEE will exercise its best efforts to operate the 
Refuse Gas Collection System and Project so as to permit effective 
utilization of the system for both environmental and energy recovery 
purposes to the greatest extent possible.  In the event that both goals 
cannot be met simultaneously, the collection of Refuse Gas for the purpose 
of environmental compliance will not be considered interference with 
LESSEE's right to collect Refuse Gas for energy recovery purposes under the 
terms of this Lease and any action by LESSOR necessary to comply with any 
environmental statues, laws, ordinances, regulations, decisions, or orders 
by any regulatory authority or entity will not be deemed a breach of this 
Lease.

9.     Removal and Restoration.

     9.1 Removal of Facilities. LESSEE shall notify LESSOR, upon expiration 
or termination of this Lease, of LESSEE's intention to either remove or 
abandon the above-ground property, fixtures, and improvements owned by 
LESSEE which LESSEE has placed on the Landfill.  LESSEE shall within six 
(6) months after said expiration or termination remove such above- ground 
property, if LESSOR requests that such above-ground property be removed.  
Upon said expiration or termination, any and all wells, together with 
attendant collection facilities, constituting LESSEE's below surface 
recovery system will, at LESSOR's election, either be transferred to LESSOR 
without further liability to LESSEE, or will be modified and/or abandoned 
at LESSEE's cost in a manner necessary to render such recovery system safe 
under the then applicable regulations.

     9.2  Surface Restoration.  LESSEE shall within six (6) months after 
the expiration or termination of this Lease restore the surface of the 
Landfill affected by LESSEE's operations to render such areas generally 
compatible with the unimproved and unlandscaped portions of the Landfill 
surface not so affected.

10.     Compliance with Law.  LESSEE shall, at its sole expense, obtain, 
maintain, and comply with all necessary governmental authorizations, 
permits and licenses required to conduct its operations under this Lease.  
In addition, LESSEE shall comply with all applicable federal, state and 
local laws, rules, regulations, and orders in its operations hereunder 
including compliance with all applicable safety and health requirements as 
to LESSEE's employees.

11.     Laws and Force Majeure.

     11.1  Laws and Force Majeure.  The provisions of this Lease shall be 
subject to all valid and applicable federal, state, county, municipal, and 
other governmental laws, executive orders, ordinances, rules, regulations, 
and acts, and this Lease shall not be terminated, in whole or in part, nor 
shall LESSEE be held liable in damages, for failure to comply herewith, if 
compliance is prevented by, or the failure is the result of, any such law, 
order, ordinance, rule, regulation, or act, or due to Force Majeure.

<PAGE>

     11.2  Effect on Operations.  If LESSEE's operations are at any time 
prevented or affected by any of the causes referred to in Section 11.1, the 
performance of its operations to the extent so prevented or affected shall 
be excused without liability hereunder, and this Lease shall continue in 
full force and effect until LESSEE is permitted to resume its operations 
and thereafter for the balance of the primary term and for as long 
thereafter as Refuse Gas and/or Constituent Products are produced to be 
sold from the Landfill.

12.     Warranty of Title.

     12.1  General.  LESSOR hereby warrants and agrees to defend the title 
to the Landfill and the Refuse Gas and/or Constituent Products produced by 
the Landfill.

     12.2  LESSOR's Interest.  It is agreed that if LESSOR owns an interest 
in the Refuse Gas and/or Constituent Products produced by the Landfill 
which is less than the entire and undivided ownership or fee simple estate 
therein, the royalties due hereunder to LESSOR shall be reduced to the 
proportion thereof which the interest actually owned by LESSOR bears to the 
whole and undivided ownership or fee therein.

     12.3  Protection of LESSEE's Interest.  If and whenever it shall be 
necessary, in order to protect LESSEE's interest hereunder, LESSEE may at 
its option, upon sixty (60) days prior to written notice, pay and discharge 
at any time any mortgage, taxes, or other liens now or hereafter attaching 
to the Landfill or any part thereof in the event of default of payment by 
LESSOR.  In such event LESSEE shall be subrogated to all of the enforcement 
rights of the owner or holder thereof, and LESSEE shall have the right to 
apply royalties accruing hereunder toward satisfying the same.

13.     Default.

     13.1  Default by LESSEE.  In the event that LESSOR concludes LESSEE's 
operations are at any time not being conducted in compliance with the 
provisions of this Lease, LESSOR shall notify LESSEE in writing of the 
facts relied upon as constituting a breach hereof, and LESSEE, if in 
default, shall have ninety (90) days after receipt of such notice in which 
to substantially complete compliance with such provisions.  LESSOR shall 
have the right to terminate this Lease upon written notice to LESSEE if 
LESSEE fails to complete or substantially complete such compliance efforts 
within the ninety (90) day period, unless such failure is excused by the 
provisions of Section 11 hereof.

     13.2  Default by LESSOR.  In the event that LESSEE concludes LESSOR at 
any time is failing to perform or observe any of the provisions of this 
Lease required to be performed or observed by LESSOR, LESSEE shall notify 
LESSOR in writing of the facts relied upon as constituting a breach hereof, 
and LESSOR, if in default, shall have ninety (90) days after receipt of 
such notice in which to complete or substantially complete compliance with 
such provisions.  LESSEE shall have the right to terminate this Lease upon 
written notice to LESSOR if LESSOR 

<PAGE>

fails to complete or substantially complete such compliance efforts within 
the ninety (90) day period, unless such failure is excused by the 
provisions of Section 11 hereof.

14.     Indemnification.  LESSOR shall defend, indemnify, and hold LESSEE, 
its officers, agents, and employees harmless from and against any and all 
claims, demands, actions, proceedings, liability, or losses of whatsoever 
nature (including reasonable attorney's fees) for injury or death to 
person(s) or for damage or loss to property arising out of or caused by 
LESSOR's operations or activities in connection with the Landfill or any 
contiguous or non- adjacent property under LESSOR's control unless such 
injury, death, damage or loss is caused by the willful misconduct or 
negligence of LESSEE.  LESSEE shall defend, indemnify, and hold LESSOR, its 
officers, agents, and employees, harmless from and against any and all 
claims, demands, actions, proceedings, liability, or losses of whatsoever 
nature (including reasonable attorney's fees) for injury or death to 
person(s) or for damage, or loss to property arising out of or caused by 
LESSEE's operations or activities in connection with the Landfill or any 
contiguous or non-adjacent property under LESSEE's control unless such 
injury, death, damage, or loss is caused by the willful misconduct or 
negligence of LESSOR.

15.     Insurance.

     (a)     Worker's Compensation Insurance.

          Before entering upon the performance of this Lease, LESSEE shall 
furnish LESSOR satisfactory evidence that LESSEE has secured, for the term 
of the Lease, full worker's compensation insurance from a responsible 
insurance company authorized to do business in the State of California and 
approved by LESSOR's Risk Management Officer.  Such insurance shall be 
maintained in full force and effect at LESSEE's own expense during the life 
of the Lease.

     (b)     Liability Insurance.

          LESSEE shall maintain, in full force during the term of this 
Lease, comprehensive general liability insurance, comprehensive automobile 
liability insurance (including coverage for owned, non-owned, and hired 
automobile hazards) and contractual liability insurance.  Liability 
insurance required by this Section shall contain at least a $1,000,000 
combined single limit.  LESSOR shall be added as an additional insured on 
all liability insurance policies required by this Section, as respects work 
done by LESSEE under the terms of this Lease.  All liability insurance 
policies required by this Section shall be primary insurance (for claims 
arising out of LESSEE's operations), and any insurance maintained by the 
LESSOR shall be excess insurance.  Moreover, LESSEE shall file with LESSOR, 
prior to commencement of work required by this Lease, a certificate of 
insurance stating that the liability coverages required by this Section are 
in effect and containing the following clauses:

<PAGE>

          (i)     "It is agreed that this policy shall not be canceled, 
non-renewed, or reduced in scope of coverage until after 30 days written 
notice has been given the Risk Management Officer, County of Orange."

          (ii)     "County of Orange is an additional insured under 
insurance policies evidenced by this certificate, as respects work done by 
the named insured for the County of Orange."

          (iii)     "Insurance evidenced by this certificate is primary 
insurance for claims arising out of the named insured's operations, and any 
insurance maintained by the County of Orange shall only provide coverage in 
excess of the insurance evidenced by this certificate."

     Insurance coverage in the minimum amounts set forth herein shall not 
be construed to relieve LESSEE for liability in excess of such coverage.

16.     LESSEE's Interests.  LESSEE is not a public utility and does not 
intend to dedicate to public use the Refuse Gas and/or Constituent Products 
produced by the Landfill or any of its facilities.  Nothing contained in 
this Lease shall be deemed a dedication by LESSEE to the public of any 
Refuse Gas and/or Constituent Products or of any of LESSEE's facilities.  
If any regulatory body shall at any time assert jurisdiction over LESSEE as 
a public utility by reason of this Lease, LESSEE shall have the right at 
such time, on at least thirty (30) days  written notice to LESSOR, to be 
relieved of all obligations hereunder not theretofore accrued (except as 
provided in Section 9 hereof), and this Lease shall thereupon terminate.

17.     Assignment.

     17.1  Assignment.  No performance of this Lease or any portion thereof 
may be assigned or subcontracted (other than subcontracting for 
engineering, fabrication, and construction of LESSEE's gas recovery 
facilities) by LESSEE without the express written consent of LESSOR, which 
consent shall not be unreasonably withheld.  Any attempt by LESSEE to 
assign or subcontract (other than subcontracting for said engineering, 
fabrication, and construction services) any performance of this Lease 
without the express written consent of LESSOR, which consent shall not be 
unreasonably withheld, shall be void and shall constitute a breach of this 
Lease.  Said subcontracting shall not relieve LESSEE of its obligations 
under this Lease.  Whenever LESSEE is otherwise authorized to subcontract 
or assign, such subcontract or assignment shall incorporate and be subject 
to the terms of this Lease.  The encumbrance of any stock or interests of 
LESSEE in the aggregate exceeding twenty-five percent (25%) shall be deemed 
an assignment within the meaning of this Section.

     17.2  Change of Ownership.  No change or division in the ownership of 
the Landfill or assignment of the royalties shall operate to enlarge the 
obligations or diminish the rights of either LESSOR or LESSEE, and no 
change, division, or assignment of such rights shall be binding 

<PAGE>

upon either LESSOR or LESSEE until thirty (30) days after LESSOR or LESSEE 
has been furnished with the original or a certified copy of the recorded 
instrument evidencing the same.

     17.3  LESSEE Restructuring.  It may be necessary or desirable for 
LESSEE to assign or pledge all or some of its Lease interest under this 
Lease, and/or all or some of LESSEE's other rights and obligations 
hereunder including those rights involving Refuse Gas and/or Constituent 
Products, to a related or unrelated third party or to a successor in 
interest to LESSEE's business and/or activities at the Landfill.  
Notwithstanding any other provisions of this Lease to the contrary, LESSOR 
agrees that such assignments or pledge shall be permitted under the terms 
of this Lease, and that upon LESSEE's request, LESSOR will not unreasonably 
withhold its consent in accordance with this Section 17.3 to the particular 
terms and conditions of such assignment or pledge through the written 
consent of LESSOR; provided, however, that no such assignment or pledge 
shall relieve LESSEE of its primary responsibility to LESSOR for 
performance of its obligations under this Lease, without the written 
consent of LESSOR.

18.     Notices.  Any  notice to be given under the Lease shall be in 
writing and shall be deemed to have been properly given and received (i) 
when delivered in person to the authorized representative of the party to 
whom the notice is addressed, or (ii) on the date received as indicated on 
the return receipt when sent by prepaid certified or registered mail, 
return receipt requested, to the party to be notified at its address, as 
follows:

          Attention:     Engineering Manager

                         and

                    Santa Ana, CA  92702-4106

     To LESSOR as to Royalty Payments:

          County of Orange
          Office of Auditor-Controller
          Post Office Box 1955
          Santa Ana, CA  92702

LESSOR or LESSEE may change such representative or address by written 
notice of said change of representative or address given to the other.

19.     Taxes.

     19.1  Taxes Paid by LESSEE.  LESSEE shall, during the term of the 
Lease, pay all taxes that may be levied upon or assessed against the 
facilities, equipment, and improvements constructed or installed by LESSEE 
in, on, or adjacent to the Landfill under this Lease.  It is understood and 
agreed that all taxes and assessments (including but not limited to a 
possessory interest tax) which become due and payable upon said facilities, 
equipment, and improvements shall be the full responsibility of LESSEE, and 
LESSEE shall cause said taxes and assessments to be paid promptly.

     19.2  Shared Taxes.  Pursuant to California Revenue and Taxation Code 
Section 107.6, LESSEE has been advised that any possessory property 
interest in the quantity or value of Refuse Gas and/or Constituent Products 
in place or recovered and/or produced from the Landfill may be subject to 
taxation.  If and to the extent property taxes (as differentiated from 
income, sales, or franchise type assessments) are levied on said interest, 
LESSEE shall pay all of such taxes levied against LESSEE's 7/8ths share, 
and LESSOR shall be responsible for paying, or be declared exempt from 
paying a 1/8th share of said taxes.

20.     Liquidated Damages.  Time is of the essence in the performance of 
this Lease.  Subsequent to commencement of gas sales hereunder, in addition 
to amounts payable under Section 4.0 above, it is agreed by and between 
LESSOR and LESSEE hereto that in the event the operational services 
thereafter are not provided within the number of calendar days as agreed 
upon herein, damage will be thereby sustained by LESSOR, and that it is and 
will be impracticable and extremely difficult to ascertain and determine 
the actual damage which LESSOR will sustain by reason of such delay; and it 
is therefore agreed that LESSEE will pay to LESSOR the sum of one hundred 
dollars ($100) per day for each and every day's delay in providing the 
operational services thereafter in excess of the number of days prescribed; 
and LESSEE agrees to said liquidated damages as herein provided.  Neither 
LESSOR nor LESSEE 

<PAGE>

shall be assessed with liquidated damages during any delay subsequent to 
commencement of gas sales caused shall LESSEE be assessed with liquidated 
damages for delay caused by failure of LESSOR to provide or perform those 
items of work required of LESSOR in this Lease; provided, however, LESSEE 
shall have no claims for any compensation for any such LESSOR delay.  
Should LESSEE be delayed by reason of alterations, including Lease 
amendments, ordered by LESSOR or by any act of LESSOR, not contemplated by 
the Lease, the time of completion will be extended appropriately by LESSOR, 
and LESSEE will not be assessed liquidated damages for such extension; 
provided, however, LESSEE shall have no claim for any other compensation 
for any such extension unless specifically set forth on a change order.

21.     Disputes.  Should LESSEE and LESSOR fail to agree on an issue 
involving Lease interpretation, either LESSOR or LESSEE may submit a 
written explanation to the other, specifying in detail the particulars of 
the Lease requirements which are not being correctly interpreted.  LESSOR 
and LESSEE shall thereafter utilize their best efforts to mutually resolve 
any potential claim within thirty (30) County of Orange Integrated Waste 
Management Department working days after receipt of such written 
explanation.  Should they fail to resolve the matter, the parties may 
proceed with a mutually agreed upon form of arbitration.

22.     Compliance with Civil Rights Laws.  LESSEE shall comply with all 
state and federal laws relating to civil rights.  LESSEE further agrees 
that no person shall be excluded from employment on the grounds of race, 
color, religion, sex, national origin, marital status, age, or as an 
otherwise qualified physically disabled individual.

23.     General Provisions.  

     23.1  Successors.  Subject to Sections 17.1 and 17.3 hereof, the 
provisions of this Lease shall inure to the benefit of and be binding upon 
LESSOR or LESSEE and their respective representatives, successors, assigns, 
and delegatees.

     23.2  Covenants and Conditions.  Each provision of this Lease 
performable by LESSOR or LESSEE, respectively, shall be deemed both a 
covenant and condition.

     23.3  Entire Contract.  All obligations of LESSEE and LESSOR under 
this Lease are expressly stated herein, and no other obligations or 
covenants are to be implied hereunder.

     23.4  Modifications.  No changes to Lease terms, conditions or 
schedules for any purpose shall be made unless approved in writing by both 
the LESSOR and LESSEE.

     23.5  Waiver.  The waiver by either LESSOR or LESSEE of any failure on 
the part of the other to perform in accordance with any of the terms or 
conditions of this Lease shall not be construed as a waiver of any future 
or continuing failure, whether similar or dissimilar thereto.

     23.6  Affiliates.  In determining whether LESSEE has complied with its 
obligations hereunder, the acts of corporations or other firms, 
organizations, and persons bearing the 

<PAGE>

relationship to LESSEE of parent, subsidiary, affiliate, representative, or 
associate shall be deemed the acts of LESSEE.

     23.7  Captions.  Section numbers and Section captions are inserted for 
identification purposes only and are not a part hereof.

     23.8  Recording.  This Lease shall not be recorded, but the parties 
shall execute and acknowledge a short memorandum of this Lease for 
recording purposes in a form mutually agreed by LESSOR and LESSEE.

     23.9  Cumulative Remedies.  No remedy or election hereunder shall be 
deemed exclusive but shall be cumulative, wherever possible, with all other 
remedies at law or in equity.  
IN WITNESS WHEREOF, LESSOR and LESSEE hereto have executed this Amended and 
Restated Lease Agreement on these dates opposite their respective 
signatures.

Section 3.04) for failure to deliver Buyer's Gas Requirements.

<PAGE>
Section 3.02     Notwithstanding anything to the contrary contained herein, 
Buyer shall not be required to accept and purchase the Minimum Daily 
Quantity of Landfill Gas, during periods when (i) events of Force Majeure 
or scheduled maintenance of Buyer's Facility undertaken in accordance with 
Section 5.03 prevent Buyer from using such quantities of Landfill Gas in 
the operation of Buyer's Facility and (ii) events of Force Majeure or the 
fault of third parties prevent Buyer from otherwise utilizing or disposing 
of such quantity of Landfill Gas.  During periods when both clauses (i) and 
(ii) apply, Buyer shall only be required to accept and purchase Landfill 
Gas delivered to the Delivery Point in such quantities as Buyer can use in 
Buyer's Facility and/or otherwise use or dispose of.

Section 3.03     Subject to the terms, conditions and limitations of this 
Agreement, Seller shall sell and deliver to Buyer at the Delivery Point a 
quantity of Landfill Gas on each day equal to 100% of the Gas requirements 
of Buyer's Facility for such day; provided that Seller's obligation to sell 
and deliver Landfill Gas on any day shall not exceed the Minimum Daily 
Quantity.  If Seller is unable for any reason to deliver Landfill Gas in 
such quantities it may, at its election, deliver substitute Gas to Buyer at 
the Deliver Point; provided however, that Seller's right to deliver 
substitute Gas, and Buyer's obligation to accept and purchase the same, 
shall be limited to that quantity of substitute Gas that Buyer can use at 
Buyer's Facility and still maintain "qualifying facility" status for 
Buyer's Facility under the Public Utility Regulatory Policies Act of 1978 
and the regulations, orders and decisions of the Federal Energy Regulatory 
Commission promulgated pursuant thereto.

Section 3.04     Notwithstanding anything to the contrary contained herein, 
Seller shall be required to tender to Buyer at the Delivery point, unless 
instructed otherwise by Buyer, the Monthly Commitment of Gas for each month 
during the term of this Agreement.  If Seller fails to tender the Monthly 
Commitment of Gas, Seller shall pay to Buyer, as liquidated damages, an 
amount calculated in accordance with Exhibit C (the "Gas Shortfall 
Liquidated Damages").  Buyer shall provide Seller with access to records 
pertaining to the sale of electrical power for the purpose of calculating 
such Gas Shortfall Liquidated Damages.  Payment of the Gas Shortfall 
Liquidated Damages shall be Seller's sole liability and Buyer's sole remedy 
for costs, liabilities and damages incurred by Buyer as a result of 
Seller's failure to deliver Landfill Gas or substitute Gas in accordance 
with this Agreement; provided that this Section shall not limit Buyer's 
rights of termination and specific performance set forth in Sections 10.03 
and 10.07, respectively, of this Agreement.

Section 3.05     Seller shall have the right of first refusal to supply any 
requirements Buyer may have for Gas in addition to its requirements for 
Buyer's Facility.

                          ARTICLE IV - DELIVERY

Section 4.01     All Gas delivered by Seller to Buyer pursuant to this 
Agreement shall be delivered at the delivery point immediately prior to 72-
E-115 Gas/Gas Exchanger as 

<PAGE>

specified in Exhibit A (the "Delivery Point").  Deliveries of Gas hereunder 
shall commence upon the Effective Date.

Section 4.02     Seller shall supply Gas to Buyer at a pressure of not less 
than seventy five pounds per square inch gauge (75 psig) at the Delivery 
Point.

Section 4.03     During any period in which Buyer's Facility is generating 
electrical power, Buyer shall provide to Seller, at no cost to Seller, the 
lesser of (i) all electrical power required by Seller for operation and 
maintenance of Seller's Facility (but not to exceed 1,500 KW) or (ii) the 
total amount (net of internal use) of electrical power being produced by 
Buyer's Facility.  In addition, Buyer shall, at Seller's request, pass 
through electrical power from the Utility to Seller, across Buyer's 
electric transmission lines, at any time Seller requires more electrical 
power the Buyer is able to supply.  Seller shall promptly reimburse Buyer 
for the cost of any such electric power passed through from the Utility to 
Seller.

Section 4.04     Title and risk of loss to Gas shall pass to Buyer at the 
Deliver point.  Seller warrants title to all Gas delivered hereunder, that 
Seller has the right to sell and receive payment for the same, and that 
such Gas shall be free from liens and adverse claims of every kind at time 
of delivery, including but not limited to liens to secure payment of 
production, severance and other taxes.

Section 4.05     All Gas delivered to Buyer hereunder shall meet the 
quality specifications set forth in Exhibit D.  Seller shall monitor Gas 
quality in accordance with conformance with said specifications, and, upon 
any such rejection, Seller shall have the right to reprocess, if possible, 
or shall otherwise be required to dispose of or use such non-conforming 
Gas.  Buyer's rejection of Gas in accordance with this Section 4.05 shall 
not relieve Seller of its obligations under Section 3.04.  Buyer may, at 
its option, elect to accept, at any time or from time to time, Gas not 
meeting any or all of said specifications; provided however that (i) such 
acceptance shall not constitute a waiver of Buyer's continuing right to 
refuse to take Gas not meeting said specifications and (ii) Seller shall 
not be liable for any damage to Buyer's Facility resulting in whole or in 
part form Buyer's use of nonconforming Gas.

Section 4.06     EXCEPT FOR THE EXPRESS WARRANTIES OF TITLE AND QUALITY SET 
FORTH IN SECTIONS 4.04 AND 4.05 ABOVE, SELLER MAKES NO WARRANTY OR 
REPRESENTATION OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED.  ALL IMPLIED 
WARRANTIES, INCLUDING THOSE OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
PURPOSE, ARE HEREBY EXCLUDED BY AGREEMENT OF THE PARTIES.

Section 4.07     As between the parties hereto, (i) Seller shall be deemed 
to be in control and possession of the Gas prior to delivery hereunder and 
responsible for any injuries, claims, liabilities or damages caused thereby 
prior to delivery at the Delivery 

<PAGE>

Point and (ii) Buyer shall be deemed to be in control and possession of the 
Gas delivered hereunder and responsible for any injuries, claims, 
liabilities or damages caused thereby after delivery at the Delivery Point.  
The party in control and possession of the Gas shall indemnify and hold 
harmless the other party with respect to any injuries, claims, liabilities 
or damages occurring while the Gas is in the former's control and 
possession.

Section 4.08     Seller shall make Gas available, and Buyer shall accept 
such Gas, throughout the term of this Agreement, on a twenty-four (24) hour 
per day basis at the Delivery point.  In addition, Seller shall use its 
reasonable efforts to provide Gas during the course of each day at volumes 
consistent with operation of Buyer's Facility.

                    ARTICLE V - OPERATION AND MAINTENANCE

Section 5.01     Seller shall, at its own expense and regardless of who may 
be the operator of Seller's Facility (which operator shall be a prudent 
operator in the industry), maintain, operate, and preserve Seller's 
Facility in good working order and condition, ordinary wear and tear 
excepted, and in conformity with applicable laws, rules and regulations.  
Seller shall obtain or cause to be obtained, and shall comply with, any and 
all governmental and other authorizations or permits necessary to locate 
and operate Seller's Facility and to collect, process and sell Landfill Gas 
as required hereunder.

Section 5.02     Buyer shall, at its own expense and regardless of who may 
be the operator of Buyer's Facility (which operator shall be a prudent 
operator in the industry, it being acknowledged that GSF Energy Inc. is a 
prudent operator), maintain, operate, and preserve Buyer's Facility at all 
times in good working order and condition, ordinary wear and tear excepted, 
and in conformity with applicable laws, rules and regulations.  Buyer shall 
obtain or cause to be obtained, and shall comply with, any and all 
governmental and other authorizations or permits necessary to locate and 
operate Buyer's Facility and conduct Buyer's business, and purchase and use 
Landfill Gas.

Section 5.03     The parties shall use reasonable efforts to schedule 
downtime for their respective facilities during the same time period 
(anticipated to occur during the months of April through June) so as to 
minimize interruptions in the delivery and acceptance of Gas hereunder.  
The parties shall establish a schedule of downtime for each Contract Year 
at the beginning of such year and shall each give the other party not less 
than 30 days prior notice of changes in such schedule.

                             ARTICLE VI - PRICE

Section 6.01     The purchase price for all Gas delivered by Seller to, and 
purchased by, Buyer during the first Contract Year shall be $0.63 per 
MMBtu.  For each subsequent Contract Year, the purchase price for all Gas 
delivered and purchased shall be escalated at 3.7% over the prior Contract 
Year's price.

<PAGE>

     The purchase price for Gas delivered by Seller to Buyer during any 
extension of this Agreement beyond December 31, 2004 shall be based upon 
(i) Seller's total costs (internal and third party expenses, including 
royalty payments) of extracting, processing and delivering Gs to Buyer and 
operating and maintaining Seller's Facility including administrative costs 
and allocated overheads plus (ii) 10% of the total cost determined under 
clause (i) of this sentence.  The detailed price terms shall be negotiated 
by the parties of the time of the first extension of this Agreement.

Section 6.02     Seller shall be responsible for payment of the Royalties 
and Seller shall indemnify Buyer against any claims, costs, losses or 
expenses incurred by Buyer in connection with such Royalties.  Buyer shall 
provide to Seller the information Seller reasonably requires, or is 
required to furnish to the Landfill Owner under the Gas Lease Agreement, 
with respect to the calculation and payment of Royalties, including records 
pertaining to sales of electrical power, and shall permit Seller and the 
Landfill Owner reasonable access on at least five (5) days prior written 
notice to electrical power sales records for such purpose.

Section 6.03     All production (including ad valorem type production 
taxes), gathering, severance or other tax, excise or assessment upon the 
existence or production of Gas delivered hereunder, now in existence or 
authorized in the future for collection by any governmental agency or duly 
constituted authority ("Seller's Taxes"), shall be paid entirely by Seller.  
All sales, utility or other tax, excise or assessment upon or measured by 
Gas sold or delivered to Buyer hereunder, or Buyer's purchase, ownership or 
use of Gas, now in existence or authorized in the future for collection by 
any governmental agency or duly constituted authority ("Buyer's Taxes"), 
shall be paid entirely by Buyer.  Should Seller be required at any time to 
pay Seller's Taxes on behalf of Seller, then the party required to pay the 
other party's taxes shall notify such other party in writing, stating the 
amount thereof, and such other party shall reimburse the paying party said 
amount within fifteen (15) days from date of notice.  Further, nothing 
herein shall be construed to obligate either party to reimburse the other 
for any federal or state capital stock, net income, windfall or excess 
profits taxes or general franchise taxes imposed on corporations on account 
of their corporate existence or on their right to do business within the 
state as a foreign corporation.

                         ARTICLE VII - MEASUREMENT AND TESTING

Section 7.01     Buyer shall install and maintain mutually agreeable 
metering and other appropriate facilities for the purpose of measuring the 
volume and Btu content of all Gas delivered by Seller to Buyer pursuant to 
this Agreement.  Seller shall have access to such metering and Seller shall 
continuously measure the volume of gas delivered to Buyer and shall sample 
such Gas to determine its Btu content on a daily basis.

Section 7.02     Buyer shall calibrate the metering facilities, and adjust, 
clean or repair such facilities to eliminate any inaccuracy, on the first 
working day of each 

<PAGE>

calendar quarter or more frequently as Buyer may determine.  Seller shall 
have the right to request a special calibration of Buyer's metering 
facilities at any reasonable time; however, if any such special calibration 
shows that such metering facilities were registering with five percent (5%) 
accuracy, then the cost of such special calibration shall be borne by 
Buyer.  In the event any calibration of a metering facility does not 
register within Five (5%) accuracy, then the volume and/or Btu content of 
Gas theretofore delivered and received shall be recalculated and corrected 
to eliminate the entire inaccuracy for any period of inaccuracy definitely 
known.  If any such period of inaccuracy is not definitely known, then such 
recalculation shall only be made for a period covering one-half of the 
elapsed time since the last calibration, not to exceed a period of forty-
five (45) days.

Section 7.03     Each party shall have the right to have its 
representatives and agents present at any installing, reading, cleaning, 
changing, repairing, inspecting, testing, calibrating, or adjusting done in 
connection with the metering facilities used in measuring deliveries of Gas 
hereunder.  The records and charts from such metering facilities shall 
remain the property of Seller, but Seller shall permit Buyer reasonable 
access upon at least five (5) days' prior written notice to such records 
and charts, together with calculations therefrom, for inspection and 
verification.

Section 7.04     Seller shall monitor and test the Gas periodically (at 
least twice monthly) at its expense for purposes of determining whether the 
quality specifications set forth in Exhibit D are being met.  The results 
thereof shall promptly be made available to Buyer and will be deemed 
conclusive unless Buyer requests a re-test.  Buyer shall have the right to 
test or re-test the Gas for said purposes through the services of an 
outside independent laboratory.  If Buyer requests a test or re-test of the 
Gas, Buyer shall pay the cost of said test or re-test if Gas is found to 
meet the quality specifications set forth in Exhibit D; otherwise the costs 
shall be paid by the Seller.  It is understood and agreed that both parties 
shall have access to any test results and shall have the right to be 
represented and to witness all tests as well as the right to inspect and 
test any equipment in determining Gas quality.

                           ARTICLE VIII - PAYMENT

Section 8.01     On or before the fifteenth day of each month following the 
first month of deliveries of Gas pursuant to this Agreement, Seller will 
furnish to Buyer a billing certificate for the preceding month, signed by 
an appropriate representative of Seller and showing the volume and Btu 
content of Gas sold, the relevant price for such Gas, the aggregate 
purchase price payable for such month for all Gas, and any adjustments to 
previous billings pursuant to Sections 7.03 and 8.04 hereof.  Seller's 
billing certificate shall also show any Gas Shortfall Liquidated Damages 
due for the preceding month, which damages, if any, shall be credited 
against amounts due Seller.

Section 8.02     For payment purposes, the Btu content of the Gas delivered 
in any month hereunder shall be equal to the sum of the MMBtus delivered in 
each day during 

<PAGE>

such month.  The MMBtus delivered in each day shall be calculated by taking 
the product of (i) the volume of Gas delivered during such day and (ii) the 
Btu content of the Gas sample taken on such day.  Such calculations of Btu 
content shall be subject to any recalculation pursuant to Section 7.02 
hereof.

Section 8.03     Buyer shall pay Seller on the basis of its billing 
certificate within fifteen (15) days of receipt.  All undisputed sums 
payable hereunder which are not timely paid as set forth herein shall bear 
interest calculated from the date when due until such sums are paid at one 
and one-half percent (1.5%) per annum above the fluctuating rate of 
interest announced publicly by Chase Manhattan Bank N.A. in New York, New 
York from time to time as its prime commercial rate.  Interest shall be 
calculated on the basis of a thirty (30) day month, three hundred sixty 
(360) day year.  In no event shall the rate of interest charged hereunder 
exceed the maximum rate allowed by applicable law.

Section 8.04     If all information required for payment and statement 
purposes for any month is not available, Buyer shall nevertheless pay on 
the basis of the estimated billing certificate.  Seller shall, as soon 
thereafter as possible, submit a corrected billing certificate.  Any 
overpayment by Buyer pursuant to such estimated statement shall be credited 
against Buyer's payment obligations for the next month, and any 
underpayment shall be paid within fifteen (15) days of receipt.

Section 8.05     If any party shall dispute an amount owing to the other 
party, such party shall (a) give notice to the other party of such disputed 
amount together with sufficient information to allow the other party to 
understand the nature of the dispute, which notice shall contain 
substantiation and shall be delivered on or before the due date of the 
amount disputed; and (b) pay undisputed amounts on the due date.  Interest 
at the rate specified in Section 8.03 shall accrue from the original due 
date on disputed amounts, or the portions thereof, ultimately determined to 
be due and payable.

Section 8.06     Each party shall have the right to inspect and examine at 
all reasonable times and upon reasonable prior notice the records and 
charts of the other party pertaining to the purchase and sale of Gas 
hereunder or any other charge or fee arising under this Agreement.  If any 
overcharge or undercharge in any amount whatsoever shall at any time be 
found and the bill therefore has been paid, Seller shall refund the amount 
of the overcharge or Buyer shall pay the amount of the undercharge within 
thirty days after the final determination thereof; provided, however, that 
no retroactive adjustment will be made for any overcharge or undercharge 
beyond a period of twenty-four months from the date the discrepancy 
occurred.

                      ARTICLE IX - LAWS AND FORCE MAJEURE

Section 9.01     The parties shall comply with all laws, rules and 
regulations, whether federal, state, or local, which are now or which may 
in the future become applicable to the processing, sale, delivery and use 
of Gas delivered hereunder.

<PAGE>

Section 9.02     this Agreement shall not be terminated, in whole or in 
part, nor shall either party be held liable in damages, for failure to 
comply herewith, if compliance is prevented by, or the failure is the 
result of, any valid and applicable federal, state, county, municipal and 
other governmental laws, executive orders, ordinances, rules, regulations 
and acts (including any change in environmental permit limits, rules or 
regulations affecting either party), or due to Force Majeure.

Section 9.03     If Seller's operations are at any time prevented or 
affected by any of the causes referred to in Section 9.02, then, subject to 
the provisions of Section 3.04, the performance of its obligations to the 
extent so prevented or affected shall be excused without liability 
hereunder, and this Agreement shall continue in full force and effect until 
Seller is permitted to resume its operations and thereafter for the balance 
of the Term hereof.  If Buyer's operations are at any time prevented or 
affected by any of the causes referred to in Section 9.02, then, subject to 
the provisions of Section 3.02, the performance of Buyer's obligations to 
the extent so prevented or affected shall be excused without liability 
hereunder.

                 ARTICLE X - DEFAULT, TERMINATION AND LIABILITY

Section 10.01     The Seller shall be in default of this Agreement, if and 
only if one or more of the following occur:

     (a)     Seller fails to pay (through credit against amounts owed 
Seller hereunder or otherwise) liquidated damages due to Buyer pursuant to 
Section 3.04 hereof within 60 days after the same shall become due; or

<PAGE>

     (b)     Seller fails to perform a material obligation of this 
Agreement, including the occurrence of a Material Performance Failure, and 
such causes Buyer to default under, and suffer a termination of the Power 
Contract; provided, it is agreed that Seller's failure to deliver Gas shall 
not constitute a default unless and until a Material Performance Failure 
shall have occurred; or

     (c)     Seller becomes insolvent or ceases to pay its debts as they 
mature or makes an arrangement with or for the benefit of its creditors or 
consents to or acquiesces in the appointment of a receiver, trustee or 
liquidator for any substantial part of its property, or a bankruptcy, 
winding up, reorganization, insolvency, arrangement or similar proceeding 
is instituted by or against the Seller under the laws of any jurisdiction 
which is not dismissed within sixty (60) days of its institution.

Section 10.02     The Buyer shall be in default of this Agreement, if and 
only if one or more of the following occur:

     (a)     Buyer fails to pay amounts due to Seller hereunder within 60 
days after the same shall become due;

     (b)     Buyer fails to perform a material obligate of this Agreement 
and does not remedy such failure within sixty (60) days after receiving 
written notice from Seller describing such failure and its materiality (or 
if such failure cannot reasonably be remedied within such sixty day period, 
Buyer does not commence a remedy within such sixty day period and 
diligently complete such remedy within a reasonable time period under the 
circumstances); or

     (c)     Buyer becomes insolvent or ceases to pay its debts as they 
mature or makes an arrangement with or for the benefit of its creditors or 
consents to or acquiesces in the appointment of a receiver, trustee or 
liquidator for any substantial part of its property, or a bankruptcy, 
winding up, reorganization, insolvency, arrangement or similar proceeding 
is instituted by or against the Buyer under the laws of any jurisdiction 
which is not dismissed within sixty (60) days of its institution.

Section 10.03     If Seller or Buyer shall be in default of this Agreement, 
as provided in Section 10.01 or Section 10.02 respectively, then the non-
defaulting party may, upon not less than 30 days prior written notice, 
terminate this Agreement.  Any such termination shall be without liability 
or either party to the other (except for payment obligations owed through 
the termination date) and such right of termination shall be in addition to 
the right of specific performance contained in Section 10.07.

Section 10.04     Buyer shall have the right to terminate this Agreement 
upon sixty (60) days' Notice to Seller upon the full expenditure by Seller 
of its Maximum Liability Cap (including any increase as provided below) 
over the Term of this Agreement as set forth in Section 10.08 (c), unless 
Seller agrees within said sixty (60) day Notice period to increase said 
aggregate limit of liability by $500,000 above the amount of liability for 
which Seller would otherwise then be liable (without giving effect to such 
Maximum Liability Cap).  Termination pursuant to this Section 10.04 shall 
be without liability of either Party to the other except for liability 
previously accrued which expressly survives termination of this Agreement.

Section 10.05     Should either party at any time during the term hereof be 
declared a public utility or public service corporation by any governmental 
body and thereby become regulated as such, this Agreement shall, either (i) 
at the option of the party subject to such regulation or (ii) if the non-
regulated party will be materially, adversely affected by reason of such 
other party's being subject to such regulation, at the option of the non-
regulated party, be terminated upon thirty (30) days written notice to the 
other party without resulting liability of either party to the other 
hereunder.

Section 10.06     It is understood that the Buyer has entered into this 
Agreement as a result of obtaining Buyer's Facilities and an assignment of 
the Power Contract.  Buyer shall immediately notify Seller in the event of 
termination of the Power Contract.  In the event that the Power Contract is 
terminated through no fault of the Buyer, and provided Buyer has exercised 
reasonable efforts for at least 180 days to obtain a substitute agreement 
for the purchase of power from Buyer's Facility, Buyer may terminate this 

<PAGE>

Agreement without liability (except for payment obligations owed through 
the termination date) hereunder to Seller.  For the purpose of this 
Agreement, Buyer will be deemed to have "no fault" if Buyer has not 
defaulted in any of its obligations under the Power Contract, and Buyer has 
taken all reasonable actions to exercise options, renew or extend the terms 
of the Power contract so as to provide for the continued sale of 
electricity during the term of this Agreement.  If Buyer terminates this 
Agreement due to the termination of the Power contract, Buyer shall provide 
Seller with the maximum notice available to Buyer of such termination and 
further shall provide Seller with substantial evidence that said 
termination is through "no fault" of Buyer.  Said evidence shall be 
provided to Buyer prior to the date of termination.

Section 10.07     Due to the unique relationship of the Buyer and Seller as 
purchaser and seller, in the event of breach of this Agreement, pecuniary 
damages would be inadequate compensation and there would be no adequate 
remedy at law.  Consequently, the parties agree that (i) if Landfill Gas is 
being recovered at the Property and sold by Seller, then Buyer shall be 
entitled to a decree of specific performance and (ii)if Buyer's Facility is 
operating, then Seller shall be entitled to a decree of specific 
performance, in each such case without necessity of proof of irreparable 
injury.

Section 10.08     Limitation of Liability.

     (a)     Limitation of Seller Liability.  Notwithstanding any provision 
of the Agreement to the contrary except for the provisions of subsection 
(e) hereof, the liability of Seller, Seller's agents, contractors,

negligence whether of Seller or others), strict liability or otherwise.  
The provisions of this Section 10.08 providing for limitations of or 
protections against the Seller's and Buyer's liability shall survive 
completion of the services hereunder or termination, cancellation, or 
expiration of the Agreement, and such provisions shall apply to the full 
extent permitted by law.

     (e)     Exceptions.  (i) Paragraph (a) of this Section 10.08 shall not 
limit or abrogate the obligation of the Seller to pay the Gas Shortfall 
Liquidated Damages and (ii) paragraph (b) of this Section 10.08 shall not 
limit or abrogate the obligation of the Buyer to pay the purchase price for 
Gas (including the purchase price for the Minimum Daily Quantity).

                             ARTICLE XI - DISPUTES

Section 11.1     Dispute Resolution.  If any dispute as to the construction 
or application of this Agreement arises between the parties, then the 
parties shall negotiate in good faith to resolve such dispute.  If the 
parties are unable to resolve the dispute to their mutual satisfaction

each party shall select one (1) arbitrator from a list provided by the 
American Arbitration Association, and the two (2) arbitrators thus selected 
by the parties shall together select the third (3rd) arbitrator from such 
list.  Each arbitrator shall be qualified by education, experience and 
training to decide the issues to be arbitrated.

majority decision of the arbitrators shall be final, binding and conclusive 
upon the parties and judgment may be entered thereon in any federal or 
state court having jurisdiction.

<PAGE>

Section 11.2     Enforcement of Arbitration Award.  Any arbitration award 
rendered in accordance with this Article XI shall be enforceable by each
