Algonquin LNG, Inc., a Delaware corporation ("ALNG") and The Providence Gas
Company, a Rhode Island corporation ("Customer").

W I T N E S S E T H:

  WHEREAS, ALNG proposes to construct, install, own, operate and maintain
certain new facilities at ALNG's existing liquefied natural gas ("LNG") storage
facility located in Providence, Rhode Island ("Project"); and

  WHEREAS, Customer desires to obtain from ALNG firm storage and regasification
service which will be made available as a result of the Project;

  NOW, THEREFORE, in consideration of the mutual covenants and agreements herein
contained, and intending to be legally bound, ALNG and Customer agree to the
following:

     1.     Subject to the terms and conditions of this Precedent Agreement,
ALNG shall proceed with due diligence to obtain from all governmental and
regulatory authorities having competent jurisdiction over the premises the
authorizations and/or exemptions ALNG determines are necessary: (i) for ALNG to
construct, own, operate, and maintain the ALNG facilities necessary to provide
the firm LNG service contemplated herein; (ii) for ALNG to make the necessary
revisions and/or modifications to its FERC Gas Tariff to reflect the firm LNG
service contemplated herein; and (iii) for ALNG to perform its obligations as
contemplated in this Precedent Agreement.  ALNG reserves the right to file and
prosecute any and all applications for such authorizations and/or exemptions,
any supplements or amendments thereto, and, if necessary, any court review, in a
manner it deems to be in its best interest.  Customer expressly agrees to
support and cooperate with, and to not oppose, obstruct or otherwise interfere
with in any manner whatsoever, the efforts of ALNG to obtain all authorizations
and/or exemptions and supplements and amendments thereto necessary for ALNG to
provide the firm LNG service contemplated in this Precedent Agreement and to
perform its obligations as contemplated by this Precedent Agreement.

     2.     Within thirty (30) days after execution of this Precedent Agreement,
Customer will advise ALNG in writing of:  (i) any facilities which Customer must
construct, or cause to be constructed, in order for Customer to utilize the firm
LNG service contemplated in this Precedent Agreement; and (ii) any necessary
authorizations, approvals and/or exemptions (governmental, internal or
otherwise) for Customer to execute and/or utilize the Service Agreement
contemplated in Paragraph 4 of this Precedent Agreement and/or to construct or
cause to be constructed any facilities necessary for Customer to utilize the

     3.     Subject to the terms and conditions of this Precedent Agreement,
Customer shall proceed with due diligence to obtain on a timely basis all
necessary internal and third party authorizations and all necessary governmental
and regulatory authorizations and/or exemptions for customer: (i) to construct
and operate, or cause to be constructed and operated, any facilities necessary
to enable Customer to fully utilize the firm LNG service contemplated in this
Precedent Agreement; (ii) to execute the Service Agreement contemplated in
Paragraph 4 of this Precedent Agreement; and (iii) to perform its obligations as
contemplated in this Precedent Agreement.  Customer reserves the right to file
and prosecute applications for such authorizations and/or exemptions, any
supplements or amendments thereto, and, if necessary, any court review, in a
manner it deems to be in its best interest; provided, however, Customer shall
pursue such authorizations and/or exemptions and any supplements and amendments
thereto in a manner designed to implement the firm LNG service contemplated
herein in a timely manner and Customer shall in no event take any action that
would obstruct, interfere with or delay ALNG's receipt of the authorizations
and/or exemptions and any supplements and amendments thereto contemplated
hereunder or otherwise jeopardize implementation of the firm LNG service
contemplated in this Precedent Agreement.  ALNG agrees to use reasonable efforts
to assist Customer in obtaining all authorizations necessary for Customer to
utilize the firm LNG service contemplated in this Precedent Agreement.  Customer
agrees to promptly notify ALNG in writing when each of the required
authorizations, approvals and/or exemptions are received, obtained, rejected or
denied.

                                       3

Customer shall also promptly inform ALNG as to whether any such authorizations,
approvals, and/or exemptions received or obtained are acceptable to Customer.


     4.     To effectuate the firm LNG service contemplated herein, Customer and
ALNG are contemporaneously executing a service agreement under ALNG's Rate
Schedule FST-LG ("Service Agreement").  Effective with the commencement of
service under the Service Agreement, the Service Agreement will supersede and
cancel the service agreement between Customer and ALNG included as part of
ALNG's FERC Gas Tariff, Fourth Revised Volume No. 2, as Rate Schedule X-4.  Such
Service Agreement will: (i) specify a Contract Storage Quantity ("CSQ") of
600,000 dekatherms ("Dth"), exclusive of fuel requirements; (ii) specify a
maximum daily vaporization quantity of 95,000 Dth per day; (iii) specify a
primary term commencing on the date of execution of the Service Agreement and
continuing in full force and effect until and including May 1, 2009, provided,
however, that subject to twelve months prior written notice, Customer shall have
the right to extend the term of Service Agreement through and including May 1,
2019;  (iv) provide for ALNG to receive Customer's LNG, in liquid phase at
ALNG's Providence, Rhode Island storage facility and store and redeliver, either
in liquid or gaseous phase, LNG to Customer, or for Customer's account; and (v)
be subject to ALNG's system rates, in effect from time to time, plus Boiloff, as
provided for in ALNG's FERC Gas Tariff.  Service under the Service Agreement
will commence on the date specified by ALNG in its written notice to Customer

     5.     Prior to commencement of service under the Service Agreement, ALNG

set forth in Paragraph 8 of this Precedent Agreement have been satisfied, or
waived by the party for whose benefit the condition was imposed, and ALNG is
ready and able to commence such firm LNG service.  As of the commencement of
service under the Service Agreement, ALNG will stand ready to provide firm LNG
service for Customer pursuant to the terms of the Service Agreement and Customer
will pay ALNG for all applicable charges associated with the Service Agreement.

     6.     ALNG will undertake the design of facilities and any other
preparatory actions necessary for ALNG to complete and file its certificate
application(s) with the Commission.  Upon satisfaction of the conditions

service utilizing the firm LNG capacity to be made available by the facilities
contemplated in this Precedent Agreement) with due diligence to construct the
authorized ALNG facilities and to implement the firm LNG service contemplated in
this Precedent Agreement on or about November 1, 1999.  Notwithstanding ALNG's
due diligence, if ALNG is unable to commence the firm LNG service for Customer
as contemplated herein by November 1, 1999, ALNG will continue to proceed with
due diligence to complete arrangements for such firm LNG service, and commence
the firm LNG service for Customer at the earliest practicable date thereafter.

Agreement be subject to cancellation if ALNG is unable to complete the
construction of such authorized and necessary ALNG facilities and commence the
