and set over unto Assignee, and Assignee accepts from Assignor,
that portion of Assignor's service entitlement as shipper under the
Contract equal to 333.6 10 3m3 per day (the "Assigned Volume"),
together with the corresponding rights and obligations of Assignor
as shipper under the Contract.

2.          Subject to Paragraphs 6 and 8 herein, during the
operative term of this Assignment, Assignee hereby covenants and
agrees that it shall perform and observe the covenants and
obligations of Assignor as shipper contained in the Contract
insofar as they pertain to the Assigned Volume, to the same extent
as Assignee would be obligated so to do were Assignee a party to 

the Contract, as shipper, with a service entitlement thereunder
equal to the Assigned Volume.

3.          This Assignment shall be in full force and effect as of
and from 08:00 hours on November 1, (the "Date of First Delivery")
(provided that, for the purposes of Assignee nominating service for
the Date of First Delivery, this Assignment shall become effective
as at 08:00 hours on the date immediately preceding the Date of

operative for a term ending at 08:00 hours on November 1, 1994. 
Notwithstanding the foregoing, the operative term of this
Assignment shall not extend beyond the term of the Contract.

4.          In the event that Assignee fails to comply with paragraph
2 hereof, Assignor shall have the right to terminate this
Assignment by following the termination procedure set forth in
Section XVII of the General Terms and Conditions contained in
TransCanada's Transportation Tariff as if Assignor were
TransCanada, Assignee were Shipper and this Assignment was the
Contract for this purpose.

5.          Assignor will request TransCanada to acknowledge the
assignment herein and to treat Assignee as shipper with a service 
entitlement under the Contract equal to the Assigned Volume during
the operative term of this Assignment.  Assignee hereby consents to
such request and to such treatment, and for this purpose Assignee
declares that all notices, nominations, requests, invoices, and
other written communications may be given by TransCanada to
Assignee as follows:

(i)         Mailing address:              25 Research Drive

Assignor shall remain responsible for all gas imbalances (as such
term is defined in Section XXII of the General Terms and Conditions

Consequently, Assignee shall indemnify Assignor for and hold
Assignor harmless from all charges that TransCanada may be entitled
to collect from Assignor under the Contract in regard to the
Assigned Volume in the event that Assignee fails to pay them.

7.          Assignee shall be entitled to sub-assign all or part of 
the Assigned Volume, together with the corresponding rights and
obligations under the Contract, to a third party by assigning all
or part of its rights and obligations under this Assignment;
provided that no such assignment shall relieve Assignee of its
obligations to Assignor hereunder without Assignor's prior written
consent, which consent shall not be unreasonably withheld. 
Notwithstanding any such sub-assignment or sub-assignments,
Assignor is and will remain obligated to TransCanada to perform and
observe the covenants and obligations of shipper that are contained
in the Contract in regard to the Assigned Volume insofar as
TransCanada is concerned.

any option or right to renew or otherwise extend the operative term
of the Contract which may be contained in or granted by the
Contract.

9.          Assignee acknowledges that it has (or may obtain directly
from TransCanada) a copy of the Transportation Tariff.

parties hereunder are subject to all valid and applicable present
