GENERAL TERMS AND CONDITIONS (Cont'd)

(c) Transporter further recognizes that exceptions to the levels of daily curtailment resulting from

Section 32.4 above may be required to avoid impairment of service for Priority 3(a) (essential industrial

process and feedstock) and Priority 3(b) (other feedstock and process gas) uses, as each are defined in

Section 32.2, during periods when, absent the curtailment of residential, small commercial, other high-

priority and essential agricultural uses, deliveries of gas in excess of curtailed levels are necessary to

satisfy said essential industrial process and feedstock uses within contractual entitlements. Any Shipper

seeking an exemption from curtailment under this Subsection (c) shall have the burden of establishing under

oath the minimum quantity of gas needed to protect said essential industrial process and feedstock uses. In

such event, Shipper may be exempted from daily curtailment to the extent necessary to satisfy said Priority

3(a) and Priority 3(b) uses; provided, however, that Transporter shall exempt deliveries for Priority 3(a)

uses prior to exempting deliveries for Priority 3(b) uses.

32.7 Transporter's Obligation to Serve.

Transporter shall have or obtain sufficient gas supply to serve Shippers' Annual Sales Quantities.

Where a deficiency in gas supply is caused by reason of force majeure events, as that term is defined in

General Terms and Conditions Section 15, Transporter shall be deemed to have met this obligation. The

curtailment procedures set forth in this Section 32 shall be utilized in the event of any supply deficiency.
