                             GAS PURCHASE AGREEMENT

THIS AGREEMENT made and entered into this 1st day of March 1991, but with an
effective date to be retroactive to October 1, 1990, by and between ENERGAS
CORPORATION ("Seller") and ENERGAS PIPELINE COMPANY ("Buyer") concerns the
sale of natural gas by Seller to Buyer as follows:

         I.    NATURE OF SERVICE

         1.1   The parties hereto recognize that the sale and purchase of gas
hereunder will be contingent on the execution by Buyer and Seller of a
PURCHASE NOMINATION NOTICE in the form attached hereto as Exhibit "A". It is
expressly understood that Buyer shall have no right to purchase and Seller
shall have no obligation to sell any gas under this Agreement unless there is
a fully executed PURCHASE NOMINATION NOTICE in effect. The parties hereto
further recognize that during any period in which a fully executed PURCHASE
NOMINATION NOTICE is in effect, the sale and purchase of gas hereunder will
also be contingent on Buyer arranging for the transportation of Seller's gas
to be purchased hereunder, on terms and conditions satisfactory to Buyer in
its sole discretion, by the Receiving Pipeline{s) described in the then
effective PURCHASE NOMINATION NOTICE, from the Seller's Delivery Point(s)
described therein to Buyer's resale markets.

         II.   TERM

         2.1   This agreement shall become effective on the first of the month
of the date hereof and shall continue in full force and effect for a primary
term of five (5) Contract Years and from year to year thereafter. Either
party shall have the right to terminate this Agreement at the expiration of
the primary term or on any anniversary of said date thereafter by giving the
other party sixty (60) days prior written notice.

         III.  QUANTITY

         3.1   Subject to the terms of this Agreement, Seller does hereby
commit to sell to Buyer, on a best reasonable efforts basis, and Buyer does
hereby agree, on a best reasonable efforts basis, to purchase a mutually
agreeable volume of gas as set forth in a then effective PURCHASE NOMINATION
NOTICE. Buyer and Seller recognize that, due to transportation limits and
market curtailments, Buyer may be unable to purchase and receive the entire
volume of gas contemplated by this Agreement, which may be available from
Seller during any effective PURCHASE NOMINATION NOTICE. Should Buyer be
unable to purchase and receive from Seller the entire volume of gas which is
available pursuant to the terms and conditions of this Agreement, then Seller
shall have the right to sell such excess gas to other parties until Buyer can
resume full contractual purchases. Notwithstanding any provision to the
contrary in this Section III, it is expressly understood that Buyer shall not
be obligated to purchase any minimum quantities of gas or pay

                                       1

         IV.   PRICE

         4.1   Buyer shall pay Seller for all the gas delivered by Seller to
Buyer hereunder at the Delivery Point(s) described in the then effective
PURCHASE NOMINATION NOTICE the price specified in such PURCHASE NOMINATION
NOTICE for the Nomination Period set forth in such PURCHASE NOMINATION NOTICE.

         4.2   In the event that Buyer and Seller do not reach an agreement on
the price, quantity or other terms and conditions of a PURCHASE NOMINATION
NOTICE, then the delivery of gas by Seller to Buyer hereunder shall be
temporarily suspended until such time as Buyer and Seller can mutually agree
on the terms and conditions of a Purchase Nomination Notice.

         V.    QUALITY AND MEASUREMENT

         5.1   All gas delivered hereunder shall be measured by a meter or
other measuring device installed and operated by the Receiving Pipeline(s)
described in a then effective PURCHASE NOMINATION NOTICE, such Receiving
Pipeline(s)'s rules, guideline and policies, shall define and set forth,
among other things, the units of measurement, measurement specifications,
quality, heating value, testing specifications and delivery terms, and
specifications of the gas to be delivered to Buyer pursuant hereto. All such
specifications and procedures of such Receiving Pipeline(s) relating to the
delivery of gas are hereby expressly incorporated herein by reference and
shall be applicable to and binding upon the parties and all natural gas sold
by Seller to Buyer.

         VI.   PASSAGE OF TITLE

         6.1 Title to all gas covered hereunder shall pass from Seller to
Buyer at the Delivery point(s) described in a then effective PURCHASE
NOMINATION NOTICE.

         VII.  WARRANTY TO TITLE

         7.1   Seller warrants for itself, its successors and assigns, that it
will at the time of delivery and throughout the term of this Agreement have good
title to all gas delivered by it hereunder, free and clear of all liens,
encumbrances and claims whatsoever; that it will at such time of delivery and
throughout the term of this Agreement have good right and title to sell and
deliver said gas; and that it will indemnify Buyer and save Buyer harmless from
all suits, actions, debts, accounts, damages, costs, losses and expenses arising
from or out of adverse claims of any and all persons to said gas or to
royalties, taxes, or other charges thereon. In the event of any claim asserted
against Seller's title to the gas delivered hereunder, Seller's right to deliver
same or the Seller's right to receive payment for all gas delivered hereunder,
Buyer may withhold payment of sums due hereunder up to the amount of such claim
until such claim is finally determined,

furnishes a bond in sufficient amount, with sureties satisfactory to Buyer,
conditioned to save Buyer free and harmless from any such claim and all
expenses incurred in investigating or defending such claim, including,
without limitation, attorney fees and costs of court.

         VIII. BILLING AND PAYMENT

         8.1   On or before the 15th day following the month of deliveries of
gas hereunder, Seller shall deliver to Buyer an invoice accompanied by a
statement for the preceding month properly identified as to the delivery
location, showing the daily and total volume of gas delivered, the amount due
and information sufficient to explain and support any calculations made by
Seller in determining the amount billed (i.e., pipeline volume statement).

         8.2   Buyer will pay Seller at the address as shown hereunder by the
later of: (i) fifteen (15) days following receipt of invoice, (ii) the twenty
fifth (25th) day of the second month following deliveries, (iii) five (5)
days following receipt of all signed Agreements and/or PURCHASE NOMINATION
NOTICES, or (iv) five (5) days following receipt of a verifiable supporting
statement. If any overcharge or undercharge in any form whatsoever shall at
any time be found and the bill therefore has been paid, Seller shall refund
the amount of the overcharge received by Seller and Buyer shall pay the
amount of the undercharge within thirty (30) days after final determination
thereof; however, no retroactive adjustment will be made for any overcharge
or undercharge beyond a period of twenty-four (24) months from the date a
discrepancy occurred. In the event a dispute arises as to the amount payable
in any statement rendered, Buyer shall nevertheless pay the amount not in
dispute to Seller pending resolution of the dispute. If it is determined that
Buyer owes Seller the disputed amount, Buyer will pay Seller that amount.

         8.3   Every notice, request, statement or bill provided for in this
Agreement shall be in writing directed to the party to whom given, made or
delivered at such party's address as set forth below and as such address may
be changed from time to time with written notice to the other party.

         (a)     Oxygen             Not more than 1% by volume

         (b)     Carbon Dioxide     Not more than 1% by volume

         (c)     Nitrogen           Not more than 3% by volume

         (d)     Hydrogen Sulfide   Not more than 1/4 grain per 100 cubic feet

                                          3

<Page>

         (e)     Mercaptan Sulfur   Not more feet than 1/10 grain per 100 cubic

         (f)     Total Sulfur       Not more than 5 grains per 100 cubic feet

         (g)     Free Water         None

         (h)     Heating Value      Not less than 1000 BTU's per cubic foot as
                                    determined per Section VII herein

         (i)     Temperature        Not more than 120 degrees Fahrenheit and
                                    not less than 40 degrees Fahrenheit

         5.2 Gatherer, at its option, may refuse to accept delivery of any
gas not meeting the quality specifications set out in this Section V;
thereafter, Producer shall have the right to conform the gas to the above
specifications. If Producer does not elect to conform the gas to said
specifications, then Gatherer' may accept gas tendered by Producer hereunder
which does not meet the specifications and, if necessary, treat same to
conform to said specifications and charge Producer the actual cost of such
treating including (but not limited to) amortization of the investment, fuel,
labor costs, taxes, and shrinkage. Such charges for treating shall be added
by Gatherer to the proceeds due from Producer under Section IX herein. If
neither Producer nor Gatherer elects to treat the gas to conform to the above
specification, then Producer may terminate this Agreement regarding any such
well upon sixty (60) days written notice; provided, however, such termination
shall be applicable only to the producing zone(s) in which the subject well
is then completed.

         VI.      MEASUREMENT

         6.1 All gas delivered hereunder shall be measured by a suitable
orifice meter or meters of standard make to be furnished, installed,
operated, and kept in repair by Gatherer at each Point of Delivery covered
hereby. However, Producer may at its option and expense install and operate
meters to check Gatherer's meter provided such check meter installation in no
way interferes with the proper operation of Gatherer's meter. The computation
of all gas volumes measured by such orifice meter shall be based on the
latest basic orifice factors published in the American Gas Association
Committee Report No.3, as amended, corrected to a base pressure of 14.65
pounds per square inch absolute (regardless of actual atmospheric pressure at
which the gas is measured) and at the actual measured flowing temperature.

         6.2 At least once every three months Gatherer shall verify the
accuracy of its measuring equipment. Gatherer shall give Producer notice of
the time of all tests of meters reasonably in advance of the holding of such
tests in order that Producer may conveniently have its representative
present. If upon test any measuring equipment is found to be in error by not
more than two percent (2%), previous recordings

                                          5

<Page>

of such equipment shall be considered accurate in computing deliveries
hereunder, but such equipment shall be adjusted at once to record correctly.

         6.3 If, on any test, Gatherer's measuring equipment is found to be
inaccurate by an amount exceeding two percent (2%) or if at any time
Gatherer's measuring equipment should be out of service or not registering,
the volume of gas delivered through the period during which the measuring
equipment was registering inaccurately or was out of service or not
registering shall be estimated by (1) using the registration of any check
meter or meters if installed and accurately registering, or (2) in the
absence of such check meter or meters, by calibration, test or mathematical
computation, or (3) in the absence of (1) and (2), the volume delivered
during any such period when a meter is out of service or registering
inaccurately shall be determined by multiplying the number of barrels of oil
or condensate produced during such period, from the wells connected to the
meter, by the average volume of gas delivered hereunder per barrel of oil or
condensate produced during the thirty (30) day period prior to the last test
of the meter reflecting accurate measurement. If the period during which
Gatherer's measuring equipment has been registering is not definitely known
or agreed upon, correction shall be made for the last half of the time
elapsed since Gatherer's measuring equipment was previously tested. All
corrections shall be made to zero error.

         6.4 If either party shall notify the other that it desires a special
test on any measuring equipment, the parties shall cooperate to secure a
prompt verification of the accuracy of such equipment. Cost of special tests
shall be borne by the party requesting same if measuring equipment is found
to be registering not more than two percent (2%) inaccurately. Said meter or
meters shall be opened to inspection at all reasonable times by Producer in
the presence of Gatherer. If requested, Gatherer shall send the charts to
Producer for checking after which they will be returned to Gatherer within
thirty days from receipt thereof.

         VII.     HEATING VALUE DETERMINATION

         7.1 Gatherer shall determine the heating value of the gas delivered
hereunder from the analysis of samples of the gas taken at the point of
measurement at Point of Delivery. Samples shall be analyzed by use of a gas
chromatograph or some other method of general use in the gas industry. The
determination shall be made quarterly, or more often if deemed necessary by
Gatherer, and each month following the determination. The heating value of
the gas shall be determined for a cubic foot of gas at a temperature of sixty
degrees Fahrenheit and at a base pressure of fourteen and sixty-five
hundredths pounds per square inch absolute (14.65), saturated basis.

         VIII. BALANCING OF GAS

         8.1 On or before the fifth (5th) day prior to the beginning of each
Accounting Period, Producer shall nominate to Gatherer a total

                                          6

<Page>

number of MCF's to be delivered hereunder into Gatherer's System at each
Point of Delivery for redelivery to Purchaser or to Transporting Pipeline for
Purchaser's account for the Accounting Period. During such Accounting Period,
Gatherer will attempt to redeliver Equivalent Quantities of gas at the
point(s) of Redelivery as are nominated by Producer prior to the beginning of
such Accounting Period, less any underdelivered volumes, if any. Gatherer
shall not be required, under any circumstances, to gather at Point of
Delivery and redeliver at the point(s) of Redelivery any volume of gas in
excess of that volume of gas so nominated by Producer prior to the beginning
of such Accounting Period.

         8.2 It is recognized that because of dispatching and other variables
certain imbalances may occur between the volume(s) of Gas delivered hereunder
by Producer and the Equivalent Quantities of Gas redelivered hereunder by
Gatherer. Such imbalances shall be corrected upon mutual agreement by the
parties within a reasonable period of time. If any such imbalances exist upon
the termination date of this Agreement, such imbalances shall be corrected
within a thirty (30) day period following such termination date.

         IX. TERM

         9.1 This Agreement shall become effective on the first of the month
of the date hereof and shall continue in full force and effect for a primary
term of five (5) Contract Years and from year to year thereafter. Either
party shall have the right to terminate this Agreement at the expiration of
the primary term or on any anniversary of said date thereafter by giving the
other party sixty (60) days prior written notice.

         9.2 In the event that Producer shuts in any of the well(s) covered
hereunder for any reason whatsoever, then the primary term of this Agreement
and the obligations of both Gatherer and Producer as contained herein shall
be extended to the beginning of the month immediately following any period of
time equivalent to such period as Producer leaves such well(s) shut in.

         X. FACILITIES

         10.1 Producer agrees to furnish, install and maintain such equipment
as may be necessary for the proper, safe and efficient operation and
maintenance of the facilities to enable it to make deliveries of gas of the
quality and pressure as provided hereunder. Such equipment shall include
automatic shut-down devices, valves and fittings necessary to permit Producer
to make its connections to Gatherer's facilities and to regulate the
deliveries according to Gatherer's requirements. In the event Gatherer
installs such facilities on Producer's behalf, Producer shall reimburse
Gatherer for its cost of installing such facilities, and shall maintain and
own such facilities after it has paid Gatherer such reimbursement.

         10.2 In the utilization and operation of such facilities, Producer

                                          7

<Page>

agrees to use its best reasonable efforts to maintain the gas at sufficiently
high temperatures to prevent the formation of gas hydrates in the gas lines
at all existing pressures in order to provide uninterrupted delivery into
Gatherer's System.

         10.3 Any naturally occurring distillates, condensates and/or liquids
accumulating in the drips, lease separators and/or lines through which the
gas flows to Gatherer's meters shall belong to and be owned by Producer, and
all distillates, condensates and/or liquids accumulating in the drips and/or
lines after the same have passed through meters at the Delivery Point(s) to
Gatherer shall belong to and be owned by Gatherer.

         XI.      WARRANTY OF RIGHT TO DELIVER AND REDELIVER

         11.1 The parties hereto warrant their respective rights to deliver
or redeliver the gas covered by this Agreement, and further, that the same is
free and clear of all liens, claims, encumbrances and specific limitations as
to use. Each party agrees as part of such warranty to indemnify, defend, and
hold the other harmless from and against any and all loss, cost, expense and
liability, including court costs and attorneys fees arising out of any
adverse claims to such gas.

         XII. INDEMNITY

         12.1 Producer shall indemnify, defend and hold Gatherer harmless
from and against all loss, cost and expense, including court costs and
attorneys fees, for any claims, suits, judgments, demands, actions or
liabilities growing out of the operations conducted hereunder by Producer or
arising while the gas is in Producer's exclusive control and possession.
Likewise, Gatherer shall indemnify, defend and hold Producer harmless from
and against all loss, cost and expense, including court costs and attorneys
fees, for any claims, suits, judgments, demands, actions or liabilities
growing out of Gatherer's operation of its equipment, pipelines and other
facilities and appurtenances thereto, or arising while the gas is in
Gatherer's exclusive control and possession.

         XIII. LAWS, REGULATIONS AND FORCE MAJEURE

         13.1 This Agreement shall be subject to all valid and applicable
laws, orders, rules and regulations made by duly constituted governmental
authorities.

         13.2 In the event either party is rendered unable, wholly or in
part, by force majeure to carry out its obligations under this Agreement
(except the obligation of Producer to make payments hereunder) the
obligations of such party, insofar as they are affected by such force
majeure, shall be suspended during the continuance of any liability so
caused, and the time of performance of an obligation herein shall be extended
to the extent of any delay caused by force majeure, but for no longer period,
and such cause shall so far as reasonably practical be remedied with
reasonable dispatch. The term "force majeure" as employed

                                          8
