activities will not be conducted in a manner that compromises the provision of
reliable and firm service to Buyer.

1.2. During the term of this Agreement, unless Seller is unable to meet
Buyer's Gas requirements, Buyer agrees that Seller shall be its supplier of Gas.
However, Buyer shall have and maintain the right to produce, utilize, purchase
or sell any and all:

(a) Gas produced in Indiana which Buyer may be required to purchase
under Ind. Code Section 8-1-2-87.6 or any successor provision thereto of
the Indiana Code; or

(b) Propane.

1.3. The Maximum Daily Quantities, which Seller shall be obligated to

1.4. The Maximum Seasonal Quantities during Winter or Summer, which Seller
shall be obligated to provide on a firm basis at the Delivery Points, are
specified in Appendix B.

1.5. Under this Agreement, Seller may fulfill its obligation to provide Gas

indemnify Seller for all expenses and costs associated with the continued
service or cause the replacement Portfolio Administration Service provider to
indemnify Seller for such costs.

1.6. If FERC should determine that Transporter's Tariff shall cease to
apply, in whole or in part, to transactions hereunder, the Parties will promptly
meet to determine and negotiate mutually acceptable replacement guidelines and
standards. In that event, until an agreement is reached, the most recently

this Agreement. Upon acceptance of the replacement guidelines and standards,
Buyer and Seller agree to apply the replacement guidelines and standards
retroactively to the cessation date of Transporter's Tariff. Any resolution
shall be implemented within thirty (30) days of the acceptance of the
replacement guidelines and standards.

1.7. As part of an agreed upon RFP process to be used to determine the
provider of gas supply services after March 31, 2007, Seller agrees that it
shall designate the pipeline transportation and storage contracts consistent
with the timing and process set forth in Article I of the Settlement. In the
event that the RFP is not conducted or the Seller is not the bidder selected as
a result of the RFP process, Seller shall assign the designated pipeline
transportation and storage contracts to the Buyer or the selected bidder, as
applicable.

1.8. To the maximum extent permitted by law, Buyer agrees Seller shall be
indemnified and discharged for all contracts held by Seller, which as part of
the process described in Section 1.7 are assigned either to Buyer or to a third
party who becomes the service provider to Buyer after March 31, 2007, and shall
no longer impose any obligations upon Seller once the assignment is made. As a
precondition to assignment, and as part of the RFP process, any such third party
or Buyer must indemnify Seller, and a discharge and release be provided from the
contract counterparty.

ARTICLE 2-GAS SALES CHARGES

2.1. For all Maximum Portfolio Entitlements, Buyer shall pay Seller each
Contract Month demand charges consistent with Section 2.5 of the Settlement, as
well as variable costs (including without limitation all volumetric charges,

listed in Appendix C.

2.2. Buyer shall pay Seller each Contract Month the applicable supplier
reservation costs specified in Appendix D.

2.3. For all commodity quantities, Buyer shall pay Seller each Contract

on a monthly basis and shall include documentation necessary for review under
the GCIM agreement and in Buyer's gas cost adjustment proceedings under Indiana
Code Section 8-1-2-42(g).

2.4. Buyer will pay taxes, including Indiana gross receipts tax, which are
imposed on or incurred by Seller due to this Agreement or imposed on Buyer with

behalf consistent with the process set forth in Section 2.5 of the Settlement.
All revenues Seller receives on Buyer's behalf shall be reported in detail on a
monthly basis to Buyer and shall be remitted to Buyer net of reported expenses
incurred by Seller in implementation of the auction. After its receipt of such
revenue, Buyer will disburse its 15% share of such revenue to Seller.

ARTICLE 3-BALANCING

3.1. Seller shall provide Buyer with Balancing Quantities as part of its

distribution, storage and transportation facilities.

4.2. The supply planning procedures set forth in Appendix F to the
Settlement will be followed by the Parties in preparing and implementing supply
plans.

approval.

4.4. Buyer and Seller will review and discuss FERC regulatory filings that
could reasonably be expected to impact the supply services provided to Buyer.

4.5. In the event this Agreement is terminated for any reason, Buyer shall
meet with Seller within five (5) days of notice of termination to reach
agreement on the timely return of capacity rights to Buyer. During such a windup
period, Seller shall continue to provide Buyer with necessary supply services
and portfolio administration services to fully meet Buyer's MDQ and MSQ. During
the wind up period, the terms and effectiveness of this Agreement shall remain
in effect. The wind up period for purposes hereof, may extend up to eighteen
(18) months. Unless terminated pursuant to Commission order under IC 8-1-2.5-7,
the termination of this Agreement shall not relieve Buyer of its executory
obligations under Article V of the Settlement.

ARTICLE 5-TERM

5.1. Unless modified by 5.2 below, the term of this Agreement shall
commence on the first day of the month following issuance of a final order in
GCA50S1 and end on March 31, 2007. If for any reason a successor has not been
chosen to assume provision of supply services to Buyer after March 31, 2007,
Seller shall continue on a month-to-month basis until a successor is chosen as
contemplated under the Settlement.

5.2. Notwithstanding 5.1 above, this Agreement may be terminated prior to
March 31, 2007 by either Party in the event of the failure by either Party to
perform in any material respect any covenant or obligation set forth in this
Agreement, and such failure is not excused by force majeure or cured within
fifteen (15) business days after written notice thereof to the Party failing to
perform; provided, however, if such failure is incapable of being cured within
such fifteen (15) business day period and the Party failing to perform has
commenced and is diligently pursuing a cure, such period shall be extended for
such time as is reasonably necessary to cure such failure up to ninety (90)
days.

5.3. This Agreement is conditioned on the continued solvency of Buyer and
Seller. If one Party becomes insolvent or seeks bankruptcy relief, the other
Party may prospectively terminate this Agreement upon prior written notice
without further obligation other than to pay for services or Gas previously
provided. In such a circumstance, the Parties will implement wind-up provisions
designed to continue reliable provision of service delivery of Gas.

ARTICLE 6-CHANGES TO APPENDICES

6.1. The Parties agree to make changes to Appendices attached to this
Agreement as necessary to reflect updates to the Agreement. Such changes shall
be consistent with the Agreement terms.

control of the Party claiming force majeure, such as an Act of God, war, civil
disturbance, operational or performance failure or declaration of force majeure
by a supplier, leased storage field operator, Transporter, or other service
provider, operational flow order(s), federal or state or local law, or binding
order of a court or governmental agency, provided the suspension shall be only
to the extent performance was prevented by the event of force majeure. A Party
claiming force majeure hereunder shall have the duty to make all reasonable
efforts to remedy the force majeure condition as promptly as possible.

8.2. Notice of force majeure must be provided with reasonably full
particulars to the other Party at or near the time the Party becomes aware of

for Buyer or Seller designated in Appendix F.

cash-outs, or other costs imposed on Buyer or Seller by any third party,

Transporters, to the extent that such penalties, cash-outs or other costs are
caused by Seller's actions or inaction. Buyer shall be liable for all imbalance
or other penalties, cash-outs, or other costs imposed on Buyer or Seller by any

applicable commodity charge, and (b) the difference between the scheduled Gas
and the quantity of Gas actually delivered by Seller. Buyer and Seller agree to

transportation, fuel and other variable costs incurred to deliver Gas to a third
party purchaser, and (b) the difference between the scheduled Gas and the
quantity of Gas actually received by Buyer. Seller and Buyer agree to cooperate
in good faith so as to minimize Buyer's obligations to Seller under this
Section.
