TRADING PARTNER AGREEMENT

for the Electronic Data Interchange

of Information Over the Public Internet

(Continued)

Section 2. Transmissions.

2.1. Proper Receipt. Documents shall not be deemed to have been

properly received until accessible to the receiving party at such party's

Receipt Computer (designated in the Appendix by Uniform Resource Locator

("URL code")), as evidenced by the receipt of the sending party of the

hyper-text transfer protocol ("HTTP") response initiated by the receiving

party indicating successful receipt of the Document in accordance with GISB

standards. No Document shall have any effect where an HTTP response is not

received by the sending party or where an HTTP response has indicated that

an error has occurred.

2.2. Verification.

2.2.1. Upon Proper Receipt of any Document, the receiving

party shall verify the legitimacy of the Document, process the

decryption of the Document as necessary, and translate the

Document in accordance with the Standards to determine whether

the Document contains all of the required data in proper

syntactical form. If the Document is legitimate and

successfully decoded, the receiving party shall transmit either

a Functional Acknowledgment or a Response Document to the

sending party by the Acknowledgment Deadline, all as set forth

in the Appendix. A Functional Acknowledgment means an ASC X12

transaction set 997, which confirms (in the format specified

thereby) whether or not all required portions of the Document

are complete and syntactically correct, but which does not

address or otherwise confirm the substantive content of the

Document. A Response Document is a transaction set in

substitution of the ASC X12 Functional Acknowledgment

transaction set 997. For purposes of this Agreement, a

Response Document confirms (in the format specified thereby)

whether or not the substantive content of the corresponding

Document contains data that is sufficiently accurate to

effectuate the communication, confirms whether or not all

required portions of the Document are complete and syntactically

correct and may contain data sent by the receiving party to the

sending party in response to the substantive content of the
