<P align="center" style="font-size: 10pt">General Terms and Conditions<BR>
Base Contract for Sale and Purchase of Natural Gas



<P align="left" style="font-size: 10pt">SECTION 1. PURPOSE AND PROCEDURES



<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">1.1. These General Terms and Conditions are intended to facilitate purchase and
sale transactions of Gas on a Firm or Interruptible basis. &#147;Buyer&#148; refers to
the party receiving Gas and &#147;Seller&#148; refers to the party delivering Gas. The
entire agreement between the parties shall be the Contract as defined in
Section&nbsp;2.7.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>The parties have selected either the &#147;Oral Transaction Procedure&#148; or the
&#147;Written Transaction Procedure&#148; as indicated on the Base Contract.</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Oral Transaction Procedure:</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">1.2. The parties will use the following Transaction Confirmation procedure.
Any Gas purchase and sale transaction may be effectuated in an EDI transmission
or telephone conversation with the offer and acceptance constituting the
agreement of the parties. The parties shall be legally bound from the time
they so agree to transaction terms and may each rely thereon. Any such
transaction shall be considered a &#147;writing&#148; and to have been &#147;signed&#148;.
Notwithstanding the foregoing sentence, the parties agree that Confirming Party
shall, and the other party may, confirm a telephonic transaction by sending the
other party a Transaction Confirmation by facsimile, EDI or mutually agreeable
electronic means within three Business Days of a transaction covered by this
Section&nbsp;1.2 (Oral Transaction Procedure) provided that the failure to send a
Transaction Confirmation shall not invalidate the oral agreement of the
parties. Confirming Party adopts its confirming letterhead, or the like, as
its signature on any Transaction Confirmation as the identification and
authentication of Confirming Party. If the Transaction Confirmation contains
any provisions other than those relating to the commercial terms of the
transaction (i.e., price, quantity, performance obligation, delivery point,
period of delivery and/or transportation conditions), which modify or
supplement the Base Contract or General Terms and Conditions of this Contract
(e.g., arbitration or additional representations and warranties), such
provisions shall not be deemed to be accepted pursuant to Section&nbsp;1.3 but must
be expressly agreed to by both parties; provided that the foregoing shall not
invalidate any transaction agreed to by the parties.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt"><B>Written Transaction Procedure:</B>


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">1.2. The parties will use the following Transaction Confirmation procedure.
Should the parties come to an agreement regarding a Gas purchase and sale
transaction for a particular Delivery Period, the Confirming Party shall, and
the other party may, record that agreement on a Transaction Confirmation and
communicate such Transaction Confirmation by facsimile, EDI or mutually
agreeable electronic means, to the other party by the close of the Business Day
following the date of agreement. The parties acknowledge that their agreement
will not be binding until the exchange of nonconflicting Transaction
Confirmations or the passage of the Confirm Deadline without objection from the
receiving party, as provided in Section&nbsp;1.3.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">1.3. If a sending party&#146;s Transaction Confirmation is materially different from
the receiving party&#146;s understanding of the agreement referred to in Section
1.2, such receiving party shall notify the sending party via facsimile, EDI or
mutually agreeable electronic means by the Confirm Deadline, unless such
receiving party has previously sent a Transaction Confirmation to the sending
party. The failure of the receiving party to so notify the sending party in
writing by the Confirm Deadline constitutes the receiving party&#146;s agreement to
the terms of the transaction described in the sending party&#146;s Transaction
Confirmation. If there are any material differences between timely sent
Transaction Confirmations governing the same transaction, then neither
Transaction Confirmation shall be binding until or unless such differences are
resolved including the use of any evidence that clearly resolves the
differences in the Transaction Confirmations. In the event of a conflict among
the terms of (i)&nbsp;a binding Transaction Confirmation pursuant to Section&nbsp;1.2,
(ii)&nbsp;the oral agreement of the parties which may be evidenced by a recorded
conversation, where the parties have selected the Oral Transaction Procedure of
the Base Contract, (iii)&nbsp;the Base Contract, and (iv)&nbsp;these General Terms and
Conditions, the terms of the documents shall govern in the priority listed in
this sentence.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">1.4. The parties agree that each party may electronically record all telephone
conversations with respect to this Contract between their respective employees,
without any special or further notice to the other party. Each party shall
obtain any necessary consent of its agents and employees to such recording.
Where the parties have selected the Oral Transaction Procedure in Section&nbsp;1.2
of the Base Contract, the parties agree not to contest the validity or
enforceability of telephonic recordings entered into in accordance with the
requirements of this Base Contract. However, nothing herein shall be construed
as a waiver of any objection to the admissibility of such evidence.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">SECTION 2. DEFINITIONS


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">The terms set forth below shall have the meaning ascribed to them below. Other
terms are also defined elsewhere in the Contract and shall have the meanings
ascribed to them herein.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">2.1. &#147;Alternative Damages&#148; shall mean such damages, expressed in dollars or
dollars per MMBtu, as the parties shall agree upon in the Transaction
Confirmation, in the event either Seller or Buyer fails to perform a Firm
obligation to deliver Gas in the case of Seller or to receive Gas in the case
of Buyer.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">2.2. &#147;Base Contract&#148; shall mean a contract executed by the parties that
incorporates these General Terms and Conditions by reference; that specifies
the agreed selections of provisions contained herein; and that sets forth other
information required herein and any Special Provisions and addendum(s) as
identified on page one.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">2.3.&#147;British thermal unit&#148; or &#147;Btu&#148; shall mean the International BTU, which is also called the Btu (IT).
<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">2.4.&#147;Business Day&#148; shall mean any day except Saturday, Sunday or Federal Reserve Bank holidays.

adjusted to the actual quantity on the following Month&#146;s billing or as soon
thereafter as actual delivery information is available.

practice to support the amount paid or disputed. In the event the parties are
unable to resolve such dispute, either party may pursue any remedy available at
law or in equity to enforce its rights pursuant to this Section.

waived unless such invoices or billings are objected to in writing, with
adequate explanation and/or documentation, within two years after the Month of
Gas delivery. All retroactive adjustments under Section&nbsp;7 shall be paid in
full by the party owing payment within 30 Days of Notice and substantiation of
such inaccuracy.

Section&nbsp;7.7 applicable to this Contract, the parties shall net all undisputed
amounts due and owing, and/or past due, arising under the Contract such that
the party owing the greater amount shall make a single payment of the net
amount to the other party in accordance with Section&nbsp;7; provided that no
payment required to be made pursuant to the terms of any Credit Support
Obligation or pursuant to Section&nbsp;7.3 shall be subject to netting under this
Section. If the parties have executed a separate netting agreement, the terms
and conditions therein shall prevail to the extent inconsistent herewith.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.3.1. As of the Early Termination Date, the Non-Defaulting Party shall
determine, in good faith and in a commercially reasonable manner, (i)&nbsp;the
amount owed (whether or not then due) by each party with respect to all
Gas delivered and received between the parties under Terminated
Transactions and Excluded Transactions on and before the Early
Termination Date and all other applicable charges relating to such
deliveries and receipts (including without limitation any amounts owed
under Section&nbsp;3.2), for which payment has not yet been made by the party
that owes such payment under this Contract and (ii)&nbsp;the Market Value, as
defined below, of each Terminated Transaction. The Non-Defaulting Party
shall (x)&nbsp;liquidate and accelerate each Terminated Transaction at its
Market Value, so that each amount equal to the difference between such
Market Value and the Contract Value, as defined below, of such Terminated
Transaction(s) shall be due to the Buyer under the Terminated
Transaction(s) if such Market Value exceeds the Contract Value and to the
Seller if the opposite is the case; and (y)&nbsp;where appropriate, discount
each amount then due under clause (x)&nbsp;above to present value in a
commercially reasonable manner as of the Early Termination Date (to take
account of the period between the date of liquidation and the date on
which such amount would have otherwise been due pursuant to the relevant
Terminated Transactions).


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">For purposes of this Section&nbsp;10.3.1, &#147;Contract Value&#148; means the amount of Gas
remaining to be delivered or purchased under a transaction multiplied by the
Contract Price, and &#147;Market Value&#148; means the amount of Gas remaining to be
delivered or purchased under a transaction multiplied by the market price for a
similar transaction at the Delivery Point determined by the Non-Defaulting
Party in a commercially reasonable manner. To ascertain the Market Value, the
Non-Defaulting Party may consider, among other valuations, any or all of the
settlement prices of NYMEX Gas futures contracts, quotations from leading
dealers in energy swap contracts or physical gas trading markets, similar sales
or purchases and any other bona fide third-party offers, all adjusted for the
length of the term and differences in transportation costs. A party shall not
be required to enter into a replacement transaction(s) in order to determine
the Market Value. Any extension(s) of the term of a transaction to which
parties are not bound as of the Early Termination Date (including but not
limited to &#147;evergreen provisions&#148;) shall not be considered in determining
Contract Values and Market Values. For the avoidance of doubt, any option
pursuant to which one party has the right to extend the term of a transaction
shall be considered in determining Contract Values and Market Values. The rate
of interest used in calculating net present value shall be determined by the
Non-Defaulting Party in a commercially reasonable manner.

Transactions and Excluded Transactions on and before the Early

any and all amounts owing between the parties under Section&nbsp;10.3.1, so
that all such amounts are netted or aggregated to a single liquidated
amount payable by one party to the other (the &#147;Net Settlement Amount&#148;).
At its sole option and without prior Notice to the Defaulting Party, the
Non-Defaulting Party may setoff (i)&nbsp;any Net Settlement Amount owed to the
Non-Defaulting Party against any margin or other collateral held by it in
connection with any Credit Support Obligation relating to the Contract;
or (ii)&nbsp;any Net Settlement Amount payable to the Defaulting Party against
any amount(s) payable by the Defaulting Party to the Non-Defaulting Party
under any other agreement or arrangement between the parties.

Non-Defaulting Party against any margin or other collateral held by it in
connection with any Credit Support Obligation relating to the Contract.

aggregation or setoff pursuant to Section&nbsp;10.3.2 is unascertained, the
Non-Defaulting Party may in good faith estimate that obligation and net,
aggregate or setoff, as applicable, in respect of the estimate, subject to the
Non-Defaulting Party accounting to the Defaulting Party when the obligation is
ascertained. Any amount not then due which is included in any netting,
aggregation or setoff pursuant to Section&nbsp;10.3.2 shall be discounted to net
present value in a commercially reasonable manner determined by the
Non-Defaulting Party.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">10.4. As soon as practicable after a liquidation, Notice shall be given by the
Non-Defaulting Party to the Defaulting Party of the Net Settlement Amount, and
whether the Net Settlement Amount is due to or due from the Non-Defaulting
Party. The Notice shall include a written statement explaining in reasonable
detail the calculation of such amount, provided that failure to give such
Notice shall not affect the validity or enforceability of the liquidation or
give rise to any claim by the Defaulting Party against the Non-Defaulting
Party. The Net Settlement Amount shall be paid by the close of business on the
second Business Day following such Notice, which date shall not be earlier than
the Early Termination Date. Interest on any unpaid portion of the Net
Settlement Amount shall accrue from the date due until the

two percent per annum; or (ii)&nbsp;the maximum applicable lawful interest rate.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">10.5. The parties agree that the transactions hereunder constitute a &#147;forward
contract&#148; within the meaning of the United States Bankruptcy Code and that
Buyer and Seller are each &#147;forward contract merchants&#148; within the meaning of
the United States Bankruptcy Code.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">10.6. The Non-Defaulting Party&#146;s remedies under this Section&nbsp;10 are the sole
and exclusive remedies of the Non-Defaulting Party with respect to the
occurrence of any Early Termination Date. Each party reserves to itself all
other rights, setoffs, counterclaims and other defenses that it is or may be
entitled to arising from the Contract.

netting agreement with close-out netting provisions, the terms and conditions
therein shall prevail to the extent inconsistent herewith.

<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">11.1. Except with regard to a party&#146;s obligation to make payment(s) due under
Section&nbsp;7, Section&nbsp;10.4, and Imbalance Charges under Section&nbsp;4, neither party
shall be liable to the other for failure to perform a Firm obligation, to the
extent such failure was caused by Force Majeure. The term &#147;Force Majeure&#148; as
employed herein means any cause not reasonably within the control of the party
claiming suspension, as further defined in Section&nbsp;11.2.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">11.2. Force Majeure shall include, but not be limited to, the following: (i)
physical events such as acts of God, landslides, lightning, earthquakes, fires,
storms or storm warnings, such as hurricanes, which result in evacuation of the
affected area, floods, washouts, explosions, breakage or accident or necessity
of repairs to machinery or equipment or lines of pipe; (ii)&nbsp;weather related
events affecting an entire geographic region, such as low temperatures which
cause freezing or failure of wells or lines of pipe; (iii)&nbsp;interruption and/or
curtailment of Firm transportation and/or storage by Transporters; (iv)&nbsp;acts of
others such as strikes, lockouts or other industrial disturbances, riots,
sabotage, insurrections or wars; and (v)&nbsp;governmental actions such as necessity
for compliance with any court order, law, statute, ordinance, regulation, or
policy having the effect of law promulgated by a governmental authority having
jurisdiction. Seller and Buyer shall make reasonable efforts to avoid the
adverse impacts of a Force Majeure and to resolve the event or occurrence once
it has occurred in order to resume performance.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">11.3. Neither party shall be entitled to the benefit of the provisions of Force
Majeure to the extent performance is affected by any or all of the following
circumstances: (i)&nbsp;the curtailment of interruptible or secondary Firm
transportation unless primary, in-path, Firm transportation is also curtailed;
(ii)&nbsp;the party claiming excuse failed to remedy the condition and to resume the
performance of such covenants or obligations with reasonable dispatch; or (iii)
economic hardship, to include, without limitation, Seller&#146;s ability to sell Gas
at a higher or more advantageous price than the Contract Price, Buyer&#146;s ability
to purchase Gas at a lower or more advantageous price than the
Contract Price, or a regulatory agency disallowing, in whole or in part, the
pass through of costs resulting from this Agreement; (iv)&nbsp;the loss of Buyer&#146;s
market(s) or Buyer&#146;s inability to use or resell Gas purchased hereunder,
except, in either case, as provided in Section&nbsp;11.2; or (v)&nbsp;the loss or failure
of Seller&#146;s gas supply or depletion of reserves, except, in either case, as
provided in Section&nbsp;11.2. The party claiming Force Majeure shall not be
excused from its responsibility for Imbalance Charges.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">11.4. Notwithstanding anything to the contrary herein, the parties agree that
the settlement of strikes, lockouts or other industrial disturbances shall be
within the sole discretion of the party experiencing such disturbance.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">11.5. The party whose performance is prevented by Force Majeure must provide
Notice to the other party. Initial Notice may be given orally; however,
written Notice with reasonably full particulars of the event or occurrence is
required as soon as reasonably possible. Upon providing written Notice of
Force Majeure to the other party, the affected party will be relieved of its
obligation, from the onset of the Force Majeure event, to make or accept
delivery of Gas, as applicable, to the extent and for the duration of Force
Majeure, and neither party shall be deemed to have failed in such obligations
to the other during such occurrence or event.


<P align="left" style="margin-left: 0%; text-indent: 0%; margin-right: 0%; font-size: 10pt">11.6. Notwithstanding Sections&nbsp;11.2 and 11.3, the parties may agree to
alternative Force Majeure provisions in a Transaction Confirmation executed in
writing by both parties.

effect until the expiration of the latest Delivery Period of any
transaction(s). The rights of either party pursuant to Section&nbsp;7.6 and Section
10, the obligations to make payment hereunder, and the obligation of either
party to indemnify the other, pursuant hereto shall survive the termination of
the Base Contract or any transaction.

parties hereto, and the covenants, conditions, rights and obligations of this
Contract shall run for the full term of this Contract. No assignment of this
Contract, in whole or in part, will be made without the prior written consent
of the non-assigning party (and shall not relieve the assigning party from
liability hereunder), which consent will not be unreasonably withheld or
delayed; provided, either party may (i)&nbsp;transfer, sell, pledge, encumber, or

orders or similar restraints with respect to such disclosure at the expense of
the other party.

Gas is delivered to Buyer after a zero-rated storage service under the ETA) having regard to the circumstances surrounding the
export and, where applicable, normal business practice; (ii)&nbsp;not acquire such Gas for consumption or use in Canada (other than
as fuel or compressor gas to transport such Gas by pipeline) or for supply in Canada (other than to supply natural gas liquids
or ethane the consideration for which is deemed by the ETA to be nil) before export of such Gas; (iii)&nbsp;ensure that, after such
Gas is delivered and before export, such Gas is not further processed, transformed or altered in Canada (except to the extent
reasonably necessary or incidental to its transportation and other than to recover natural gas liquids or ethane from such Gas
at a straddle plant); (iv)&nbsp;maintain on file, and provide to Seller, if required, or to the Canada Customs and Revenue Agency,
