The following instructions will assist you in filling out the EFT Authorization
Form accurately. These instructions are designed to prevent errors which cause
delays in you EFT setup. If you have additional questions, information can be
found on our internet website at http://www-1.ibm.com/procurement/proweb.nsf/
ContentDocsByTitle/United+States~EFT+Process?OpenDocument&Parent=EDI+Invoicing
or e-mail eftsetup@us.ibm.com.

TRADING PARTNER NAME:
This is the name of your company.

REMIT TO ADDRESS:

This is the address for which your invoices read "send payments to:" This is not
to be confused with your company's physical location; however it may be the
same. A rule of thumb is: Where should payments be mailed in the event a paper
check needs to be cut?

BANKING INFORMATION:

This is the physical location of the bank you use. If you use a branch, please
supply the branch's address in this section.

TITLE ON BANK ACCOUNT:

This should be the exact name as shown on your monthly Bank Statements. If the
name (Title) on your bank account differs from your company name, we will need a
written explanation on your company letterhead of the relationship between the
name on the account and your company name. This letter can be faxed in along
with the EFT Authorization Form.

EFT INFORMATION:

We recommend that you obtain this information directly from you bank. The
information needed is the Routing/ABA# (American Banking Association) of your
bank, and your company's individual Account #. When asking the bank for this
information, let them know that IBM intends to send EFT payments to you account
using the ACH (Automated Clearing House). It is important to note that IBM is
sending an EFT payment through the ACH, we are not sending a Wire payment. Wire
payments and EFT payments are not the same. For additional backup, we recommend
that you send a copy of a voided check along with the EFT Form.

BANK CONTACT:

This should be an employee of your bank whom IBM can contact to verify that the
banking information supplied is correct.

REMIT ADVICE OPTION:

This determines where IBM sends your remittance advice for payments that are
sent electronically. IBM offers two options:

Option 1: You must be an EDI/Forms Exchange (FOX)/WOI enabled supplier to use
this option. IBM will electronically send your remittance to your EDI/FOX/WOI
in-box. You will normally receive your remittance advice 1 to 2 days prior to
