1.2.2. Each party shall be responsible for the costs, acts and

omissions of any Provider with which it contracts. This

provision does not limit any claim of either party against a

Provider with respect to such acts or omissions.


1.3. System Operations. Each party, in its sole discretion and at its own

expense, shall provide for the requisite hardware, software, services

and/or testing procedures necessary to transmit, receive and retrieve



1.4. Security Procedures. Each party, in its sole discretion and expense,

shall use and provide for the requisite levels of security which are

reasonably sufficient to ensure that all transmissions of Documents are

authorized by the parties and to protect their business records and data

from improper access. At a minimum, the parties shall provide and use

those security measures specified herein, in the NAESB standards as

adopted by the FERC, or as may be agreed upon by the parties as set forth

in the Appendix.


1.5. Keys. When the parties are utilizing the Internet electronic delivery

mechanism as herein contemplated, each party shall maintain a Pretty Good

Privacy ("PGP") "public key," (an encryption algorithm used to facilitate

private electronic communication) which may be changed from time to time

in accordance with this Agreement or as may be set forth in the Appendix.

Each party shall provide to the other party its PGP public key by either

(a) a certified or receipted mail service using a diskette with the

public key contained in an ASCII text file, or (b) an electronic simple

mail transfer protocol (smtp) mail message with the public key contained

in the body. Under either option above, the public key shall be verified

by the party to whom it is sent by validating the fingerprint of the

public key which may be accomplished via telephone, fax, or other

comparably reliable means. If a party desires to change its public key,

it shall provide at least five business days prior notice thereof to the

other party; provided that under an emergency situation, a prior written

notice of at least 24 hours shall be given.


1.6. Electronic Signatures. Each party shall adopt as its signature the PGP

private key, where required by the Standards or otherwise agreed to by

the parties, in the Document transmitted by such party ("Signature

Code(s)"). Such Signature Codes(s) shall be specified in the Appendix.

Each party agrees that the Signature Code(s) of such party affixed to or

contained in any transmitted Document shall be sufficient to verify that

such party originated the Document. Neither party shall disclose to any

unauthorized person the Signature Code(s) of the other party.
