GENERAL TERMS AND CONDITIONS

(continued)

4. QUALITY OF GAS (continued)

4.4 Verification of Gas Quality. At Algonquin's request, Customer shall use all reasonable

efforts to obtain and provide to Algonquin all records regarding gas quality kept by

upstream pipelines transporting the gas received by Algonquin for Customer's account.

Customer shall use all reasonable efforts to ensure and verify for Algonquin that such

upstream pipelines are using appropriate equipment to monitor compliance with the gas

quality specifications applicable on Algonquin's system as stated in this Section 4.

4.5 Failure To Conform to Specifications. If the gas tendered by Customer for receipt by

Algonquin, or offered for delivery by Algonquin to Customer, shall fail at any time to

conform to any of the specifications set forth in this Section 4, then the party

asserting such deficiency shall notify the other of such deficiency and may, at its

option, refuse to accept nonconforming gas pending correction by Algonquin or Customer

as appropriate. Algonquin may refuse to accept gas or may impose additional gas quality

specifications and restrictions if Algonquin, in its reasonable judgment, determines

that harm to Algonquin's facilities or operations could reasonably be expected to occur

if it receives gas that fails to meet such additional specifications and restrictions.

4.6 Odorization. Algonquin shall have no obligation to odorize the gas tendered by Customer

other than to conform to the regulations of appropriate governmental authorities having

jurisdiction. However, if Algonquin odorizes the gas, such odorization shall be by use

of a malodorant agent of such character as to indicate by a distinctive odor the

presence of gas. Whenever odorized gas is delivered, the quality and specifications, as

set forth in this Section 4, of such gas shall be determined prior to the addition of

malodorant or with proper allowance for changes or additions due to such malodorant.

Such odorization of the gas by Algonquin shall be for the purpose of detection of the

gas only during the time when the gas is in the possession of Algonquin, prior to

delivery to the Customer.

4.7 Waiver of Requirements. Algonquin may waive the requirements set forth in this Section

4 in order to allow Customer to tender or cause to be tendered gas which does not, when

injected into Algonquin's pipeline, meet the quality specifications set forth in Section

4; provided that acceptance of such gas shall not adversely affect Algonquin's system

facilities or operations, and further provided that once such gas has been blended, to

the extent blending occurs, the commingled gas stream at any delivery point on

Algonquin's system shall be compliant with the quality specifications set forth in

Section 4. Algonquin shall post on LINK® any waiver of Algonquin's gas quality

requirements. Algonquin shall implement this Section 4.7 on a non-discriminatory basis

and may cancel any waiver at any time if necessary to assure that the commingled gas

stream is compliant with the quality specifications set forth in Section 4 at any

delivery point on Algonquin's system.
