Dear John:

TENNESSEE GAS PIPELINE COMPANY (TENNESSEE) AND COLONIAL GAS
COMPANY (COLONIAL) agree to amend the above referenced gas 
storage contract effective July 1, 1995, to increase the
Maximum Daily Withdrawal Quantity (MDWQ) when Shipper's
storage balance is equal to or less than 30% of the Maximum 
Storage quantity (MSQ) and 20% of the MSQ, respectively,
as reflected in the attached Exhibit A-1 and as described
below.

The parties agree to amend Article I of the subject gas storage
contract as follows:

Following the commencement of services hereunder, in accordance 
with the terms of Transporter's Rate Schedule FS, and of
this Agreement, Transporter shall receive for injection for
Shipper's account a daily quantity of gas up to Shipper's 
Maximum Injection Quantity of 7,306 dekatherms (Dth) and 
Maximum Storage Quantity (MSQ) of 1,095,830 (Dth) (on a
cumulative basis) and on demand shall withdraw from Shipper's 
storage account and deliver to Shipper a daily quantity of
gas up to Shipper's Maximum Daily Withdrawal Quantity (MDWQ)
of 14,150 Dth; provided however, that when Shipper's storage 
balance is equal to or less than 30% of the MSQ but greater
than 20% of the MSQ, the Maximum Daily Withdrawal Quantity shall 
be 12,065 Dth; and provided further, that when Shipper's
storage balance is less than or equal to 20% of the MSQ, the
Maximum Daily Withdrawal Quantity shall be 7,670 Dth.  For
demand charge purposes, the MDWQ for balances greater than 30%
of the MSQ shall be used.

Except as amended herein, all terms and provisions of the above
referenced gas storage contract shall remain in full force and
effect as written.

If the foregoing is in accordance with your understanding of our 
agreement, please so indicate by signing and returning both
originals of this letter.  Upon Tennessee's execution, an
original will be forwarded to you for your files.

Should you have any questions, please do not hesitate to contact
me at (713) 757-5125.

                         Sincerely,

			 /s/ John Templet

     void,  or  voidable,  by a court of competent  jurisdiction,

     exercised,  the remaining provisions of the Agreement  shall
     remain in full force and effect.

8.3  Unless  otherwise  expressly provided in this  Agreement  or
     Transporter's  Tariff, no modification of or  supplement  to
