First Revised Sheet No. 13 : Effective

Superseding: ORIGINAL SHEET NO.13

6.5 Injection of Storage Gas shall not be required by

Northwest at times when to do so would necessitate curtailment of

service by Northwest to any firm sales or firm transportation

customer served by Northwest or when it would otherwise

adversely affect the operation of Northwest's system.

6.6 In the event of the occurrence of a "force majeure"

condition, as defined by ARTICLE XII hereof, by any cause beyond

Northwest's control, which renders it impossible for Northwest to

maintain minimum pipeline pressures and service required to

supply firm service to any of Northwest's customers, Northwest

shall have the right to withdraw Working Gas in such quantities

and at such rates as required to restore and maintain minimum

pressure and service; provided, however, that such withdrawals

shall not jeopardize the integrity of the Storage Project.

Withdrawals of Working Gas for delivery to Water Power and

Washington Natural may be curtailed to the extent necessary

during such emergency. Northwest shall not withdraw any Cushion

Gas or reduce the volume thereof below that last previously

determined by the Committee, unless otherwise approved by the

parties hereto. Northwest shall promptly use its best efforts to

repair any such damage or impairment and shall promptly restore

to the Storage Project the amount of Working or Cushion Gas so

withdrawn by Northwest.

ARTICLE VII

Apportionment of Storage Project Capital Costs, Operating

Expenses and Losses

7.1 All capital costs, including Cushion Gas, shall be

borne and paid for by each party to this Agreement on the basis

of one-third (1/3) each.

7.2 All maintenance and operating expenses, except the

cost of gas for normal operations and compressor fuel, shall be

borne and paid for by each party to this Agreement on the basis

of one-third (1/3) each; provided, however, that each year the

parties shall review the reasonableness of sharing maintenance

and operating expenses on a one-third (1/3) basis.

7.3 Northwest shall be solely responsible for supplying the

gas used in normal operations of the Storage Project, including

compressor fuel.
