D. Election. After the process in C. is complete, each Part 284 firm shipper receiving

an allocation may elect to either take permanent assignment of its remaining

allocated share of each contract or to turn back all or a portion of its remaining

allocated share to Northern to be included in the reverse auction. Each Part 284

firm Shipper receiving an allocation may elect to take permanent assignment of, on a

no cost basis, all or any portion of the ANR Rate Schedule X-59. In the event ANR

Rate Schedule X-59 needs to be allocated among requesting Shippers, the allocation

will use each Shippers peak day entitlement, as provided in paragraph B(3) above,

divided by the total peak day entitlement of all Shippers wanting the ANR Rate

Schedule X-59.


E. Open Season for Assignment. After the elections in D. above, Northern will hold an

open season to attempt to assign the remaining portions of any unassigned contracts

to any interested creditworthy party on a no cost basis.


F. Contracts in Reverse Auction. The unassigned portions of the contracts remaining

after the close of the open season in E, will be subject to a reverse auction. The

contracts available for bid and the terms and conditions of the reverse auction will

be posted on Northern's Electronic Bulletin Board (EBB).


Any creditworthy party may bid during the reverse auction the amount of payment which

it would require as consideration for taking assignment of all or any portion of the

contracts available for bid effective November 1, 1993.


To minimize transition costs, Northern may withdraw a contract from the reverse

auction after the close of bidding if Northern believes it is able to buy out or

reform the contract for less than the lowest reverse auction bid posted. However, in

such instance, Northern will be permitted to recover as a Reverse Auction Cost only

the lesser of any amount spent to reform the contract or the lowest reverse auction

bid posted. If no bids are received during the Reverse Auction, until such contract

is assigned, bought out or reformed, Northern may recover costs associated with its

performance under such contract as price differential under the GSR Cost Recovery

Mechanism as described in Section 25 or as an Account 858 Stranded cost as described

in Section 24 as appropriate. Any buyout or reformation costs associated with such

contracts may be recovered as Reverse Auction cost. However, any shipper who

retained their initial allocation or Small Customers would not be subject to the cost

of other unassigned Account No. 858 capacity or price differential related to such

unassigned contracts as described in Section 24 and 25 of these GENERAL TERMS AND



At the conclusion of the reverse auction, Northern will assign the remaining

contracts to the lowest bidders (successful bidders) except as set forth in Appendix

G of the Global Settlement. The payments made by Northern to successful bidders

shall be treated and recovered as Reverse Auction Cost as more specifically described

in Section 22A of the GENERAL TERMS AND CONDITIONS and may be subject to a prudence

challenge as set forth in Article III, Section B.4.a. of the Global Settlement. The

prudence of any buyout, buydown or reformation claimed as a Reverse Auction Cost for

any contract withdrawn by Northern from the reverse auction may be challenged.


In the event Northern reforms a contract, Northern will offer the contract for

assignment to any shipper paying the reverse auction cost, prior to Northern being

able to retain the contract for its market-based service.


If a supplier does not consent to the assignment of two thirds (2/3) of each supply

contract, then no assignment(s) of that contract will be effectuated.


Northern has the right to "market-out" of or terminate certain gas supply contracts

prior to the expiration of the term of the related transportation agreements. Upon

the expiration of any such contract, the supplier thereunder shall have the right,

but not the obligation, to take assignment of the related transportation capacity.

In the event that any of Northern's suppliers do not exercise such right, subsequent

reverse auction(s) will be held, with assignments to be effective no later than

November 1, 1994, to assign any remaining transportation capacity. If subsequent

reverse auction(s) is held, each of the suppliers whose gas supply contract with

Northern has expired shall have a right to match any bid for the remaining

transportation capacity related to its expired contract.
