PERSONAL AND CONFIDENTIAL

BPI Industries, Inc.
30775 Bainbridge Rd.
Suite 200
Solon, Ohio 44139
Attention:  James G. Azlein, President

Dear Sir:

     We are pleased to confirm the arrangements under which KeyBanc Capital
Markets, a division of McDonald Investments Inc. ("KBCM"), and Sanders Morris
Harris, Inc. ("SMH" and, together with KBCM, the "Agents") have today been
engaged by BPI Industries, Inc. (the "Company") to serve as placement agents in
connection with the sale of securities of the Company, which may include: senior
notes, subordinated notes, preferred stock or common stock of the Company, and
if agreed upon by the Company, warrants to purchase shares of common stock of
the Company. These securities, whether or not convertible into common stock of
the Company, are referred to in this letter agreement as the "Placement
Securities."

1.   During the term of their engagement, the Agents will provide such financial
     advice and assistance in connection with this potential transaction as the
     Company may reasonably request, which may include assisting the Company in
     (a) structuring the sale of Placement Securities; (b) identifying and
     approaching parties that may have an interest in Placement Securities; (c)
     assisting the Company in the preparation of offering materials describing
     the Company and the proposed transaction; (d) coordinating the due
     diligence investigation of the Company by interested parties; (e)
     evaluating proposals from interested parties regarding Placement
     Securities; and (f) assisting the Company in negotiating the terms of the
     sale of Placement Securities. It is understood that assistance rendered by
     the Agents with respect to the offering of Placement Securities will be on
     a "reasonable efforts" basis, and no obligation on the part of either Agent
     to purchase any Placement Securities for its own account or for resale to
     third parties arises by virtue of this letter agreement.

2.   The term of this letter agreement shall run for six months from the date of
     this letter agreement, and may be extended by the mutual written consent of
     all of the parties hereto, subject to the provisions set forth below in
     paragraph 13 of this letter agreement.

3.   As consideration for their services, the Company agrees to (a) pay the
     Agents a fee in an amount equal to 8% of the aggregate purchase price paid
     by investors (the "Investors") for any Placement Securities sold during the
     term of this letter agreement in a placement contemplated by this letter
     agreement (the "Placement Fee"). In addition, the Company agrees to pay the
     Agents a Placement Fee if within six months following the termination of
     this engagement any Placement Securities are sold by the Company to any
     investor

     identified by either Agent or with whom either Agent had contact on behalf
     of the Company during the term of this letter agreement. Any such Placement
     Fee shall be paid in full in cash, to the Agents at the closing of any sale
     of Placement Securities giving rise to such Placement Fee.

4.   In addition to any Placement Fee payable by the Company hereunder and
     regardless of whether any Placement Securities are sold by the Company, the
     Company shall reimburse the Agents for all reasonable travel, legal and
     other out-of-pocket expenses incurred in performing the services described
     herein. The initial cap on the expenses shall be $100,000 and that amount
     can be adjusted by mutual agreement of the Agents and the Company. In
     addition, the Company shall engage and pay all costs and fees associated
     with Schlumberger Data Consulting Services, independent petroleum
     engineers.

5.   The company agrees to the provisions with respect to the Agents' indemnity
     and other matters set forth in Appendix A, which appendix is incorporated
     by reference into this letter agreement. Each of the Company and SMH also
     acknowledges that it has received and reviewed the Special Disclosure
     Statement of KeyCorp set forth in Schedule I, which schedule is
     incorporated by reference into this letter agreement.

6.   The Company agrees to provide the Agents with all information concerning
     the Company that the Agents reasonably deem appropriate in connection with
     their engagement hereunder and will provide the Agents with access to the
     Company's officers, directors and advisors. The Company agrees to notify
     the Agents of any material adverse change, or development that may lead to
     a material adverse change, in the business, properties, operations or
     financial condition or prospects of the Company or in the Company's ability
     to affect the sale of Placement Securities. The Company shall also inform
     the Agents of any material events or developments concerning prospective
     material events that may come to the attention of the Company at any point
     during the term of this letter agreement. The Company agrees that all
     information concerning the Company furnished by or on behalf of the Company
     to the Agents or to any prospective investor will be true and accurate in
     all material respects and will not contain any untrue statement of a
     material fact or omit to state a material fact necessary in order to make
     the statements therein, in the light of the circumstances under which such
     statements are made, not misleading. The Company acknowledges that the
     Agents will be using and relying upon the accuracy and completeness of the
     information supplied by the Company and its officers, directors and
     advisors in connection with its engagement hereunder without independent
     verification.

7.   The Company agrees that any offering document delivered to potential
     investors in connection with the offer and sale of Placement Securities
     will include all information required to be provided to such investors
     under applicable securities laws and regulations; and no such document
     shall contain an untrue statement of a material fact or omit to state a
     material fact necessary to make the statements therein, in the light of the
     circumstances

     under which they were made, not misleading; and the Company shall have
     responsibility for the accuracy and completeness of any such offering
     document.

8.   The Company agrees to furnish to the Agents the name of each party (a) with
     which the Company has had discussions or contacts (either during the term
     of this letter agreement or within twelve months prior to the date of this
     letter agreement) concerning a possible investment in securities of the
     Company, and (b) of which the Company is aware had or currently has an
     interest (either during the term of this letter agreement or within twelve
     months prior to the date of this letter agreement) in entering into a
     possible investment in securities of the Company.

9.   The Company agrees that (a) the Agents will be entitled to rely on the
     truth and accuracy of all representations and warranties made by it in any
     purchase agreement or other agreement or instrument entered into by the
     Company in connection with the transactions contemplated by this letter
     agreement and (b) it will use all reasonable efforts to cause any opinions
     of counsel to the Company and comfort or similar letters of the Company's
     accountants, in each case, that are delivered to any investor and relate to
     disclosure or securities law issues in connection with the transactions
     contemplated by this letter agreement also to be addressed and delivered to
     the Agents.

10.  Each of the parties to this letter agreement acknowledges and agrees that
     its respective rights and obligations are contractual in nature. Each party

     by virtue of the engagement contemplated by this letter agreement. This
     letter agreement is solely for the benefit of KBCM, SMH, the Company, each
     of their respective officers, directors, employees and agents, and any
     person controlling them within the meaning of the Securities Act of 1933,
     as amended, and the respective legal representatives, successors and
     assigns of KBCM, SMH and the Company, and no other person shall acquire or
     have any right under or by virtue of this letter agreement.

11.  As you know, McDonald Investments Inc. and SMH are full service securities
     firms and as such may from time to time effect transactions for their own
     accounts or the account of their customers, and they may hold positions in
     securities or options on securities of the Company.

12.  No fee payable to any other financial advisor by the Company in connection
     with the subject matter of this engagement shall reduce or otherwise affect
     any fee payable hereunder to the Agents.

13.  At any time at which both Agents are acting as placement agents hereunder,
     either Agent may resign as placement agent upon ten days' written notice to
     the Company and the other Agent. Upon any such resignation, the resigning
     Agent shall have no continuing rights, liabilities or obligations
     hereunder, except that the provisions of paragraph 4 and Appendix A of this
     letter agreement will survive any such resignation, and (b) this

     Agreement shall not terminate and the other Agents' rights, liabilities and
     obligations hereunder shall remain unchanged.

     Agents, acting together, or the Company, in each case, upon ten days'
     written notice. Upon expiration of the term of this letter agreement or
     termination of this letter agreement, no party shall have any liability or
     continuing obligation to the other under the terms of this letter
     agreement, except that the provisions of paragraphs 3 and 4, and Appendix A
     of this letter agreement will survive any such expiration or termination.

15.  The Company acknowledges that the Agents' due diligence investigation of
     the Company is ongoing and will continue for the duration of the engagement
     set forth herein. The Company further acknowledges that each Agent may
     resign as a placement agent hereunder or terminate this letter agreement
     pursuant to paragraphs 13 or 14 above, as applicable, based on information
     that comes to its attention during its due diligence investigation,
     including without limitation thorough discussions with one or more
     independent petroleum engineers and review of one or more reports of such
     independent petroleum engineers, which reports shall be satisfactory to
     each Agent in its sole discretion.

16.  EACH PARTY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY
     RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION, CLAIM
     OR PROCEEDING (WHETHER BASED UPON CONTRACT, TORT OR OTHERWISE) RELATING TO

     PURSUANT HERETO OR THE PERFORMANCE BY THE AGENTS OF THE SERVICES
     CONTEMPLATED BY THIS LETTER AGREEMENT.

17.  The Company agrees that the Agents may publish, at their own expense,
     advertisements announcing the completion of the transaction and the Agents'
     role therein.

                            MCDONALD INVESTMENTS INC.
                          SPECIAL DISCLOSURE STATEMENT

     McDonald Investments Inc. ("McDonald"), is a wholly-owned subsidiary of
KeyCorp. McDonald is a broker/dealer registered with the Securities and Exchange
Commission, and a member of the National Association of Securities Dealers, Inc.
("NASD"), the New York Stock Exchange ("NYSE") and the Securities Investor
Protection Corporation ("SIPC").

     KeyCorp is also the parent of KeyBank National Association. McDonald is not
a bank; it is a separate corporate entity from its affiliated bank subsidiaries
of KeyCorp. The obligations of McDonald are not obligations of any of its
affiliate banks, and none of the affiliated banks are responsible for, or
guarantee, the securities sold, offered or recommended by McDonald. Except in
certain specified circumstances, securities and other investment products sold,
offered or recommended by McDonald are not bank deposits or obligations, and are
not insured by the FDIC. McDonald will sell, as agent, banker's acceptances or
CD's issues by its affiliate banks and by unaffiliated third party banks. The
CD's that McDonald sells as agent are insured by the FDIC only to the extent
that the FDIC insures the deposits of the issuing bank.

     McDonald's banking affiliates may be lenders to issuers of securities that
McDonald underwrites or privately places, in which case the proceeds of
securities offerings underwritten or privately placed may be used to repay those
loans. Please refer to the relevant offering disclosure documents for a
discussion of any such lending arrangement.

     You acknowledge that McDonald may share with any of its affiliates
(including KeyBank) any information related to the transaction or any of the
matters contemplated hereby. McDonald agrees to treat, and cause such affiliates
to treat, all nonpublic information provided to it by you or any of your

                                   Appendix A

In the event that McDonald Investments Inc. or Sanders Morris Harris, Inc. (each
an "Agent" and together the "Agents") becomes involved in any capacity, other
than as a plaintiff, in any action, proceeding or investigation brought by or
against any person, including shareholders of BPI Industries, Inc. (the
"Company") in connection with any matter related to the assignment described in
this letter, the Company agrees to reimburse each Agent for its legal and other
expenses (including the cost of any investigation and preparation) reasonably
incurred in connection therewith; provided, however, that if it is finally
judicially determined in any such action, proceeding or investigation that any
loss, claim, damage or liability of such Agent has resulted from the gross
negligence or bad faith of such Agent in performing the services which are the
subject of this letter, such Agent shall repay such portion of the reimbursed
amounts that is attributable to expenses incurred in relation to the act or
omission of such Agent which is the subject of such finding. The Company also
will indemnify and hold each Agent harmless against any losses, claims, damages
or liabilities to any such person in connection with any matter related to the
assignment described in this letter, except to the extent that any such loss,
claim, damage or liability is finally judicially determined to have resulted
from the gross negligence or bad faith of such Agent in performing the services
that are the subject of this letter. If for any reason the foregoing
indemnification is unavailable to an Agent or is insufficient to hold it
harmless, then the Company shall contribute to the amount paid or payable by
such Agent as a result of such loss, claim, damage or liability in such
proportion as is appropriate to reflect the relative economic interests of the
Company on the one hand and such Agent on the other hand in the matters
contemplated by this letter as well as the relative fault of the Company on the
one hand and such Agent on the other hand with respect to such loss, claim,
damage or liability and any other relevant equitable considerations; provided,
however, that in no event shall such Agent be required to contribute any amounts
in excess of the fees received by it hereunder. The Company shall be liable for
any settlement of any claim against an Agent made with the Company's written
consent, which consent shall not unreasonably be withheld, and neither the
Company shall, without the prior written consent of such Agent, settle or
compromise any claim or permit a default or consent to the entry of any judgment
in respect thereof, unless such settlement, compromise or consent includes, as
an unconditional term thereof, the giving by the claimant to such Agent of an
unconditional release from any and all liability in respect of such claim. Each
Agent shall have the right to retain counsel of its own choice to represent it
in connection with any matter as to which the indemnity, expense reimbursement
and contribution provisions apply. The reimbursement, indemnity and contribution
obligations of the Company under this paragraph shall be in addition to any
liability which the Company may otherwise have, shall extend upon the same terms
and conditions to any affiliate of either Agent and their directors, agents,
employees and controlling persons (if any), as the case may be, and shall be
binding upon and inure to the benefit of any successors, assigns, heirs and
personal representatives of the Company, each Agent, any such affiliate and any
such person. The indemnity obligations of the Company hereunder shall not extend
to any affiliate of either Agent or any such affiliate to the extent that any
loss, claim, damage or liability is finally judicially determined to have
resulted from the gross negligence or bad faith of such Agent or any such other
person in performing the services which are the subject of the letter. The
Company also agrees that each Agent and its affiliates, directors, agents,
employees and controlling persons shall have no liability to the Company or its
shareholders, for or in connection with any matter referred to in this letter
except to the extent that any losses, claims, damages, liabilities or

<PAGE>

expenses are finally judicially determined to have resulted from the gross
negligence or bad faith of such Agent in performing the services that are the
subject of this letter. The provisions of this Appendix A shall survive any
termination or completion of the engagement provided by this letter agreement
and this letter agreement shall be governed by and construed in accordance with
the laws of the State of Ohio without regard to principles of conflicts of laws.<PAGE>

                          GENERAL TERMS AND CONDITIONS
               BASE CONTRACT FOR SALE AND PURCHASE OF NATURAL GAS

SECTION 1. PURPOSE AND PROCEDURES

1.1.    These General Terms and Conditions are intended to facilitate purchase
and sale transactions of Gas on a Firm or interruptible basis. "Buyer" refers to
the party receiving Gas and "Seller" refers to the party delivering Gas. The
entire agreement between the parties shall be the Contract as defined in
Section 2.7.

THE PARTIES HAVE SELECTED EITHER THE "ORAL TRANSACTION PROCEDURE" OR THE
"WRITTEN TRANSACTION PROCEDURE" AS INDICATED ON THE BASE CONTRACT.

ORAL TRANSACTION PROCEDURE:

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 'writing" and to have been "signed'. 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 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 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.

WRITTEN TRANSACTION PROCEDURE:

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 1.3.

1.3.    If a sending party's Transaction Confirmation is materially different
from the receiving party'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's agreement to
the terms of the transaction described in the sending party'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) a binding Transaction Confirmation pursuant to Section 1.2, (ii) 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) the Base Contract, and (iv) these General Terms and Conditions,
the terms of the documents shall govern in the priority listed in this sentence.

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 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.

SECTION 2. DEFINITIONS

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.

2.1.    Alternative Damages" 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 deriver Gas in the case of Seller or to receive Gas in the case of
Buyer.

7.2.    Buyer shall remit the amount due under Section 7.1 in the manner
specified in the Base Contract, in immediately available funds, on or before the
later of the Payment Date or 10 Days alter receipt of the invoice by Buyer;
provided that if the Payment Date is not a Business Day, payment is due on the
next Business Day following that date. In the event any payments are due Buyer
hereunder, payment to Buyer shall be made in accordance with this Section 7.2.

7.3.    In the event payments become due pursuant to Sections 3.2 or 3.3, the
performing party may submit an invoice to the nonperforming party for an
accelerated payment setting forth the basis upon which the invoiced amount was
calculated. Payment from the nonperforming party will be due five Business Days
after receipt of invoice.

7.4.    If the invoiced party, in good faith, disputes the amount of any such
invoice or any part thereof, such invoiced party will pay such amount as it
concedes to be correct; provided, however, if the invoiced party disputes the
amount due, it must provide supporting documentation acceptable in industry
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.

7.5.    If the invoiced party fails to remit the full amount payable when due,
interest on the unpaid portion shall accrue from the date due until the date of
payment at a rate equal to the lower of (i) the then-effective prime rate of
interest published under "Money Rates" by The Wall Street Journal, plus two
percent per annum; or (ii) the maximum applicable lawful interest rate.

7.6.    A party shall have the right, at its own expense, upon reasonable Notice
and at reasonable times, to examine and audit and to obtain copies of the
relevant portion of the books, records, and telephone recordings of the other
party only to the extent reasonably necessary to verify the accuracy of any
statement, charge, payment, or computation made under the Contract. This right
to examine, audit, and to obtain copies shall not be available with respect to
proprietary information not directly relevant to transactions under this
Contract. All invoices and billings shall be conclusively presumed final and
accurate and all associated claims for under- or overpayments shall be deemed
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 7 shall be paid in full
by the party owing payment within 30 Days of Notice and substantiation of such
inaccuracy.

7.7.    Unless the parties have elected on the Base Contract not to make this
Section 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 7; provided that no payment required
to be made pursuant to the terms of any Credit Support Obligation or pursuant to
Section 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.

SECTION 8. TITLE, WARRANTY, AND INDEMNITY

8.1.    Unless otherwise specifically agreed, title to the Gas shall pass from
Seller to Buyer at the Delivery Point(s). Seller shall have responsibility for
and assume any liability with respect to the Gas prior to its delivery to Buyer
at the specified Delivery Point(s). Buyer shall have responsibility for and any
liability with respect to said Gas after its delivery to Buyer at the Delivery
Point(s).

8.2.    Seller warrants that it will have the right to convey and will transfer
good and merchantable title to all Gas sold hereunder and delivered by it to
Buyer, free and clear of all liens, encumbrances, and claims. EXCEPT AS PROVIDED
IN THIS SECTION 8.2 AND IN SECTION 14.8, ALL OTHER WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR ANY
PARTICULAR PURPOSE, ARE DISCLAIMED.

8.3.    Seller agrees to indemnify Buyer and save it harmless from all losses,
liabilities or claims including reasonable attorneys' fees and costs of court
("Claims"), from any and all persons, arising from or out of claims of title,
personal injury or property damage from said Gas or other charges thereon which
attach before title passes to Buyer. Buyer agrees to indemnify Seiler and save
it harmless from all Claims, from any and all persons, arising from or out of
claims regarding payment, personal injury or property damage from said Gas or
other charges thereon which attach after title passes to Buyer.

8.4.    Notwithstanding the other provisions of this Section 8, as between
Seller and Buyer, Seller will be liable for all Claims to the extent that such
arise from the failure of Gas delivered by Seller to meet the quality
requirements of Section 5.

SECTION 9. NOTICES

9.1.    All Transaction Confirmations, invoices, payments and other
communications made pursuant to the Base Contract ("Notices") shall be made to
the addresses specified in writing by the respective parties from time to time.

9.2.    All Notices required hereunder may be sent by facsimile or mutually
acceptable electronic means, a nationally recognized overnight courier service,
first class mail or hand delivered.

9.3.    Notice shall be given when received on a Business Day by the addressee.
In the absence of proof of the actual receipt date, the following presumptions
will apply. Notices sent by facsimile shall be deemed to have been received upon
the sending party's receipt of its facsimile machine's confirmation of
successful transmission. If the day on which such facsimile is received is not a
Business Day or is after five p.m. on a Business Day, then such facsimile shall
be deemed to have been received on the next following Business Day. Notice by
overnight mail or courier shall be deemed to have been received on the next
Business Day after it was sent or such earlier time as is confirmed by the
receiving party. Notice via first class mail shall be considered delivered five
Business Days after mailing.

SECTION 10. FINANCIAL RESPONSIBILITY

10.1.   If either party ("X") has reasonable grounds for insecurity regarding
the performance of any obligation under this Contract (whether or not then due)
by the other party ("Y") (including, without limitation, the occurrence of a
material change in the creditworthiness of Y), X may demand Adequate Assurance
of Performance. "Adequate Assurance of Performance" shall mean sufficient
security in the form, amount and for the term reasonably acceptable to X,
including, but not limited to, a standby irrevocable letter of credit, a
prepayment, a security interest in an asset or a performance bond or guaranty
(including the issuer of any such security).

10.2.   In the event (each an "Event of Default") either party (the "Defaulting
Party") or its guarantor shall: (i) make an assignment or any general
arrangement for the benefit of creditors; (ii) file a petition or otherwise
commence, authorize, or acquiesce in the commencement of a proceeding or case
under any bankruptcy or similar law for the protection of creditors or have such
petition filed or proceeding commenced against it; (iii) otherwise become
bankrupt or insolvent (however evidenced); (iv) be unable to pay its debts as
they fall due; (v) have a receiver, provisional liquidator, conservator,
custodian, trustee or other similar official appointed with respect to it or
substantially all of its assets; (vi) fail to perform any obligation to the
other party with respect to any Credit Support Obligations relating to the
Contract; (vii) fail to give Adequate Assurance of Performance under Section
10.1 within 48 hours but at least one Business Day of a written request by the
other party; or (viii) not have paid any amount due the other party hereunder on
or before the second Business Day following written Notice that such payment is
due; then the other party (the "Non-Defaulting Party") shall have the right, at
its sole election, to immediately withhold and/or suspend deliveries or payments
upon Notice and/or to terminate and liquidate the transactions under the
Contract, in the manner provided in Section 10.3, in addition to any and all
other remedies available hereunder.

10.3.   If an Event of Default has occurred and is continuing, the
Non-Defaulting Party shall have the right, by Notice to the Defaulting Party, to
designate a Day, no earlier than the Day such Notice is given and no later than
20 Days after such Notice is given, as an early termination date (the "Early
Termination Date") for the liquidation and termination pursuant to Section
10.3.1 of all transactions under the Contract, each a "Terminated Transaction".
On the Early Termination Date, all transactions will terminate, other than those
transactions, if any, that may not be liquidated and terminated under applicable
law or that are, in the reasonable opinion of the Non-Defaulting Party,
commercially impracticable to liquidate and terminate ("Excluded Transactions"),
which Excluded Transactions must be liquidated and terminated as soon thereafter
as is reasonably practicable, and upon termination shall be a Terminated
Transaction and be valued consistent with Section 10.3.1 below. With respect to
each Excluded Transaction, its actual termination date shall be the Early
Termination Date for purposes of Section 10.3.1.

THE PARTIES HAVE SELECTED EITHER "EARLY TERMINATION DAMAGES APPLY" OR "EARLY
TERMINATION DAMAGES DO NOT APPLY" AS INDICATED ON THE BASE CONTRACT.

EARLY TERMINATION DAMAGES APPLY:

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) 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 3.2), for which payment has not yet been made by
the party that owes such payment under this Contract and (ii) the Market Value,
as defined below, of each Terminated Transaction. The Non-Defaulting Party shall
(x) 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) where
appropriate, discount each amount then due under clause (x) 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).

For purposes of this Section 10.3.1, "Contract Value" means the amount of Gas
remaining to be delivered or purchased under a transaction multiplied by the
Contract Price, and "Market Value" 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
"evergreen provisions") 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.

EARLY TERMINATION DAMAGES DO NOT APPLY:

10.3.1. As of the Early Termination Date, the Non-Defaulting Party shall
determine, in good faith and in a commercially reasonable manner, 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 3.2), for which payment has not yet been made by
the party that owes such payment under this Contract.

THE PARTIES HAVE SELECTED EITHER "OTHER AGREEMENT SETOFFS APPLY" OR "OTHER
AGREEMENT SETOFFS DO NOT APPLY" AS INDICATED ON THE BASE CONTRACT.

OTHER AGREEMENT SETOFFS APPLY:

10.3.2. The Non-Defaulting Party shall net or aggregate, as appropriate, any and
all amounts owing between the parties under Section 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 "Net Settlement Amount"). At its sole option and without
prior Notice to the Defaulting Party, the Non-Defaulting Party may setoff (i)
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) 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.

OTHER AGREEMENT SETOFFS DO NOT APPLY:

10.3.2. The Non-Defaulting Party shall net or aggregate, as appropriate, any and
all amounts owing between the parties under Section 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 "Net Settlement Amount"). At its sole option and without
prior Notice to the Defaulting Party, the Non-Defaulting Party may setoff 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.

10.3.3. If any obligation that is to be included in any netting, aggregation or
setoff pursuant to Section 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 10.3.2 shall be discounted to net present value in a
commercially reasonable manner determined by the Non-Defaulting Party.

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 date of payment at a rate equal to the
lower of (i) the then-effective prime rate of interest published under "Money
Rates" by The Wail Street Journal, plus two percent per annum; or (iii) the
maximum applicable lawful interest rate.

10.5.   The parties agree that the transactions hereunder constitute a "forward
contract" within the meaning of the United States Bankruptcy Code and that Buyer
and Seller are each "forward contract merchants" within the meaning of the
United States Bankruptcy Code.

10.6.   The Non-Defaulting Party's remedies under this Section 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.

10.7.   With respect to this Section 10, if the parties have executed a separate
netting agreement with close-out netting provisions, the terms and conditions
therein shall prevail to the extent inconsistent herewith.

SECTION 11. FORCE MAJEURE

11.1.   Except with regard to a party's obligation to make payment(s) due under
Section 7, Section 10.4, and Imbalance Charges under Section 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 "Force Majeure" as
employed herein means any cause not reasonably within the control of the party
claiming suspension, as further defined in Section 11.2.

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) weather related
events affecting an entire geographic region, such as low temperatures which
cause freezing or failure of wells or lines of pipe; (iii) interruption and/or
curtailment of Firm transportation and/or storage by Transporters; (iv) acts of
others such as strikes, lockouts or other industrial disturbances, riots,
sabotage, insurrections or wars; and (v) 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.

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) the curtailment of interruptible or secondary Firm
transportation unless primary, in-path, Firm transportation is also curtailed;
(ii) 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's ability to sell Gas
at a higher or more advantageous price than the Contract Price, Buyer'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) the loss of Buyer's market(s) or
Buyer's inability to use or resell Gas purchased hereunder, except, in either
case, as provided in Section 11.2; or (v) the loss or failure of Seller's gas
supply or depletion of reserves, except, in either case, as provided in Section
11.2. The party claiming Force Majeure shall not be excused from its
responsibility for Imbalance Charges.

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.

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 fun 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.

11.6.   Notwithstanding Sections 11.2 and 11.3, the parties may agree to
alternative Force Majeure provisions in a Transaction Confirmation executed in
writing by both parties.

SECTION 12. TERM

This Contract may be terminated on 30 Day's written Notice, but shall remain in
effect until the expiration of the latest Delivery Period of any transaction(s).
The rights of either party pursuant to Section 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.

SECTION 13. LIMITATIONS

FOR BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS
PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND
EXCLUSIVE REMEDY. A PARTY'S LIABILITY HEREUNDER SHALL BE LIMITED AS SET FORTH IN
SUCH PROVISION, AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE
WAIVED. IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY PROVIDED HEREIN OR IN A
TRANSACTION, A PARTY'S LIABILITY SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES ONLY.
SUCH DIRECT ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, AND ALL OTHER
REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY HEREIN
PROVIDED, NEITHER PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE,
EXEMPLARY OR INDIRECT DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION
DAMAGES, BY STATUTE, IN TORT OR CONTRACT, UNDER ANY INDEMNITY PROVISION OR
OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED
ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES
RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY PARTY, WHETHER SUCH NEGLIGENCE
BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES
REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED. THE PARTIES ACKNOWLEDGE THAT THE
DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OR OTHERWISE OBTAINING AN
ADEQUATE REMEDY IS INCONVENIENT AND THE DAMAGES CALCULATED HEREUNDER CONSTITUTE
A REASONABLE APPROXIMATION OF THE HARM OR LOSS.

SECTION 14. MISCELLANEOUS

14.1.   This Contract shall be binding upon and inure to the benefit of the
successors, assigns, personal representatives, and heirs of the respective
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) transfer, sell, pledge, encumber, or
assign this Contract or the accounts, revenues, or proceeds hereof in connection
with any financing or other financial arrangements, or (ii) transfer its
interest to any parent or affiliate by assignment, merger or otherwise without
the prior approval of the other party. Upon any such assignment, transfer and
assumption, the transferor shall remain principally liable for and shall not be
relieved of or discharged from any obligations hereunder.

14.2.   If any provision in this Contract is determined to be invalid, void or
unenforceable by any court having jurisdiction, such determination shall not
invalidate, void, or make unenforceable any other provision, agreement or
covenant of this Contract.

14.3.   No waiver of any breach of this Contract shall be held to be a waiver of
any other or subsequent breath.

14.4.   This Contract sets forth all understandings between the parties
respecting each transaction subject hereto, and any prior contracts,
understandings and representations, whether oral or written, relating to such
transactions are merged into and superseded by this Contract and any effective
transaction(s). This Contract may be amended only by a writing executed by both
parties.

14.5.   The interpretation and performance of this Contract shall be governed by
the laws of the jurisdiction as indicated on the Base Contract, excluding,
however, any conflict of laws rule which would apply the law of another
jurisdiction.

14.6.   This Contract and all provisions herein will be subject to all
applicable and valid statutes, rules, orders and regulations of any governmental
authority having jurisdiction over the parties, their facilities, or Gas supply,
this Contract or transaction or any provisions thereof.

14.7.   There is no third party beneficiary to this Contract.

14.8.   Each party to this Contract represents and warrants that it has full and
complete authority to enter into and perform this Contract. Each person who
executes this Contract on behalf of either party represents and warrants that it
has full and complete authority to do so and that such party will be bound
thereby.

14.9.   The headings and subheadings contained in this Contract are used solely
for convenience and do not constitute a part of this Contract between the
parties and shall not be used to construe or interpret the provisions of this
Contract.

14.10.  Unless the parties have elected on the Base Contract not to make this
Section 14.10 applicable to this Contract, neither party shall disclose directly
or indirectly without the prior written consent of the other party the terms of
any transaction to a third party (other than the employees, lenders, royalty
owners, counsel, accountants and other agents of the party, or prospective
purchasers of all or substantially all of a party's assets or of any rights
under this Contract, provided such persons shall have agreed to keep such terms
confidential) except (i) in order to comply with any applicable law, order,
regulation, or exchange rule, (ii) to the extent necessary for the enforcement
of this Contract, (iii) to the extent necessary to implement any transaction, or
(iv) to the extent such information is delivered to such third party for the
sole purpose of calculating a published index. Each party shall notify the other
party of any proceeding of which it is aware which may result in disclosure of
the terms of any transaction (other than as permitted hereunder) and use
reasonable efforts to prevent or limit the disclosure. The existence of this
Contract is not subject to this confidentiality obligation. Subject to Section
13, the parties shall be entitled to all remedies available at law or in equity
to enforce, or seek relief in connection with this confidentiality obligation.
The terms of any transaction hereunder shall be kept confidential by the parties
hereto for one year from the expiration of the transaction.

In the event that disclosure is required by a governmental body or applicable
law, the party subject to such requirement may disclose the material terms of
this Contract to the extent so required, but shall promptly notify the other
party, prior to disclosure, and shall cooperate (consistent with the disclosing
party's legal obligations) with the other party's efforts to obtain protective
orders or similar restraints with respect to such disclosure at the expense of
