                    ARTICLE III - PURCHASE AND SALE

Section 3.01     Subject to the terms, conditions and limitations of this 
Agreement, Buyer shall purchase and receive, if and to the extent that 
Seller delivers the same 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 except as specifically provided in Section 3.02, 
Buyer shall purchase, if and to the extent delivered at the Delivery Point, 
not less than 1,650 MMBtu per day (the "Minimum Daily Quantity") of 
Landfill Gas.

     During any extension of this Agreement beyond December 31, 2004, 
Seller shall be obligated to use its reasonable efforts to deliver 
quantities of Gas equal to the Gas requirements of Buyer's Facility, but 
shall not be obligated to guaranty Gas amounts or be subject to damages, 
liquidated or otherwise (including Gas Shortfall Liquidated Damages under 
Section 3.04) for failure to deliver Buyer's Gas Requirements.


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 



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

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 



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.



     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 



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 



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.



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



     (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 



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, 
subcontractors and suppliers, and each of their respective employees, 
officers and shareholders to Buyer or Buyer's insurers with respect to any

of this Agreement to the contrary except for the provisions of subsection 
(e) hereof, the liability of Buyer, Buyer's agents, contractors,

either; loss by reason of shutdown of Seller's Facility or inability to

of Seller's Facility or its equipment; increased costs of purchasing or 
providing equipment, materials, supplies, or services outside Buyer's scope 
of supply; 



costs of replacement capital; claims of Seller's customers; interest during

Agreement to the contrary, Buyer agrees that the aggregate liability of 
Seller to Buyer for Gas Shortfall Liquidated Damages over the term of this 
Agreement, shall not exceed $3,000,000.

10.08, the terms "liable" and "liability" mean liability of any kind 
whether based in contract (including breach of warranty), tort (including 
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).
