150-DAY UNDERGROUND STORAGE SERVICE

2. APPLICABILITY AND CHARACTER OF SERVICE (cont'd)

2.3 Subject to Subparagraph 2.4 below, Buyer will have the right to

receive and Transporter will deliver commencing November 1 and ter-

minating March 31 in each contract year (hereinafter the "With-

drawal Season") that Quantity of Gas which Buyer has in storage on

October 31 in such contract year (augmented by any quantity of

Buyer's gas injected during such Withdrawal Season) at a daily rate

not exceeding the Maximum Daily Withdrawal Quantity set forth in

the applicable Underground Storage Service Agreement (hereinafter

the "Maximum Daily Withdrawal Quantity"). During the Withdrawal

Season, as far in advance as possible and no later than the

beginning of the next preceding day, each Buyer shall notify

Transporter of the Quantity of Gas which it desires to withdraw on

each day pursuant to this Subparagraph 2.3. Such notice may be

given by telephone and shall also specify any Quantity of Gas which

Buyer desires to have withdrawn and delivered in excess of its

Maximum Daily Withdrawal Quantity pursuant to Paragraph 8 below.

Upon request, Transporter may waive any part of such advance notice

requirement, if, in its judgment, operating conditions permit.

2.4 During injection of gas hereunder, Transporter will retain a

quantity of gas equal to the product obtained by multiplying the

quantity of gas received for injection by the percentage set forth

on Sheet No. 6-A as "surface operating allowance" ("Injection

Allowance"). During withdrawal of gas hereunder, Transporter will

retain a quantity of gas equal to the product obtained by multiply-

ing the quantity of gas withdrawn by the percentage set forth on

Sheet No. 6-A as "surface operating allowance" ("Withdrawal

Allowance"). On any given day during the Injection Season, Buyer

shall be permitted to deliver Quantities of Gas to Transporter for

injection necessary to satisfy the Injection Allowance and

Withdrawal Allowance, occurring during the Injection Season as re-

ported by Transporter. Such additional Quantities of Gas will not

reduce Buyer's Maximum Daily Injection Quantity and will not be

considered in determining the Quantities of Gas subject to the

Excess Service Charge, but shall be subject to a Surface Operating

Allowance Charge.
