1.0 Introduction 1.1 Summary The vendor-direct parts (VDP) program allows AutoZone to offer our customers a wide variety of automotive parts. These parts would otherwise be unavailable because of limited space and size in our stores and warehouses. For our vendors, VDP increases the volume and range of their automotive parts sales. The keys to a successful AutoZone VDP program are: Accurate, on-time advance ship notices (ASNs) Accurate, on-time inventory quantity transmissions Accurate connection between the invoice and the airbill Electronic invoicing Consistent shipping performance. Without these five requirements, the VDP program will not succeed. 1.2 How It Works Central to the VDP program is electronic data interchange (EDI), an electronic computer communications link between the vendor and AutoZone. The graphic and explanation on the next page describe how the VDP program works. 1. Vendor transmits his current warehouse inventory quantities-on- hand (QOH) to AutoZone. 2. AutoZone transmits the vendor inventory information to the stores. 3. Customer orders a VDP part. AutoZoner creates VDP purchase order (PO), which automatically subtracts from current quantity on hand (QOH). 4. Customer PO is transmitted to AutoZone corporate computer. 5. The AutoZone system sorts and creates electronic batches of POs then transmits orders to vendor via EDI. 6. Vendor receives POs electronically, then pulls, packs, and ships parts to AutoZone store via specified carrier at a pre-determined time. AutoZone store number and PO number are identified in reference field on airbill. 4

7. Vendor sends electronic advance ship notices (ASNs) via EDI to AutoZone before 9:00 p.m. Central Time (CST), indicating shipment or cancellation information. (Vendor has the option of sending inventory quantities with ASNs.) 8. ASNs are forwarded on to stores with shipping information or notice of cancellation. 9. Vendor sends electronic invoices via EDI to AutoZone. Invoices are matched with both carrier airbills and store POs for payment approval. Vendor invoice identifies carrier and airbill number. 10. Air carrier sends EDI notice with airbill number and store number. AutoZone Customer 3. Customer orders VDP part AutoZone Store Air Carrier 10. Air carrier sends EDI notice 8.

2.0 Vendor Requirements 2.1 In-Stock Information Specific information about each SKU is needed by the AutoZone product manager prior to the start of the VDP program. Vendors will be given a 3.5-inch computer disk to set-up these items. The required information includes: Part number UPC number Item Weight Item Measurements (length/width/height in inches) Cost of item. A vendor may elect to commit inventory specifically to AutoZone or transmit all open inventory. 2.2 Inventory Accuracy On-hand inventory figures must be accurate and transmitted at any time before 9:00 p.m. Central Time daily for the VDP program to work correctly. Accurate inventory figures will ensure that stores can not order more than is actually available and will thus reduce the number of order cancellations. Vendors must send an inventory transmission for all VDP parts using the six-digit AutoZone SKU number each time they transmit. If the inventory level is zero, there must be a zero inventory transmission for that part. If a vendor decides to discontinue a part, the AutoZone product manager must be notified as soon as the decision is made. On the day the vendor decides is the last day of availability for the discontinued item, the vendor must transmit an inventory of zero. 6

2.3 EDI Documentation A vendor needs three EDI documents in addition to the PO (EDI document 850) to participate in the VDP program. These documents are defined in Section 4 of this document. 846 -- defines how inventory information is to be transmitted 856 -- defines the required ASN information 810 -- provides the layout of the vendor's electronic invoice. The EDI PO document (850) for VDP orders is the same one shown in the EDI Trading Partner Guidebook, except for the contents (not the structure) of the "SHIP TO" information. The VDP "SHIP TO" information contains store address information, whereas warehouse information is found on a normal warehouse PO. The area of EDI document 850 that normally contains the AutoZone warehouse code (i.e., 22, 33, 44, etc.) will instead contain a code of "DS", indicating a "direct ship" order. It also includes TD5 segment that contains a code for the FedEx shipping option. 2.4 Data Transmission AutoZone's VDP system can send POs to the vendor's mailbox hourly, from 6:00 a.m. to 10:00 p.m. CST every day. The EDI send times are initiated from AutoZone at the top of each hour. Vendors should start checking their mailboxes at 30 minutes after the hour. Please Note! Since there is no other practical way of assuring that AutoZone has received EDI documents sent by the vendor, the vendor must check functional acknowledgments. This involves matching 997's sent to the vendor, by AutoZone, against the batches of documents which the vendor has sent to AutoZone. If, within 24 hours, the vendor does not receive a 997 acknowledging a batch, the vendor must contact AutoZone s EDI Analyst (for contact information, please see AutoZone s Contact list on p. 12). 7

AutoZone must receive ASNs (EDI document 856) by 8:00 p.m. (CST) the day of shipment. The vendor and product manager will determine the normal purchase order cut-off time, which is usually one hour before the last air carrier pickup (CST). Vendor inventory QOH information (EDI document 846) must be received by AutoZone no later than 8:00 p.m. (CST) daily, except Saturday. This information may also be transmitted with the vendor's ASNs. Vendors must be able to re-transmit invoices or ASNs if AutoZone experiences problems with documents. Re-transmission may be required for up to six months after a purchase order is sent. In the event of a system, EDI or weather transmission interruption that prevents the vendor from shipping purchase order packages on time, the vendor must contact the AutoZone Merchandising Business Contact promptly. The Contact will ask for a list of the POs that will not be shipped. If fewer than 50 POs are on the list, the vendor will be expected to call the stores and provide a corrected ship date to the store manager. 2.5 Shipping An AutoZone Logistics representative will coordinate with the carrier to provide shipping system installation and training. That system may be either web-based or a stand-alone unit provided by a carrier. Either system must have the means to determine package weight, and must be used for the sole purpose of shipping AutoZone VDP program orders only. The appropriate shipping label(s) must be attached to each package according to the carrier specifications. AutoZone will be assigned one or more carrier account numbers for the vendor's location and is responsible for paying the carrier(s) bill. Vendors provided with an automated shipping system must execute an agreement with the carrier and provide a dedicated phone line to operate the system. Vendors must maintain an internet account if they have a web-based system in operation. AutoZone will be responsible for the execution of the approved automated shipping system. AutoZone will not be responsible for damage to the system caused by misuse or mishandling. Any unauthorized shipments made on an AutoZone account will be charged back with an administration fee added. The vendor is responsible for accurate weights and labels for each package. In addition, the vendor will enter the following order information on the Reference line of the shipping screen: Store number (four digits)/po number Example: 2763/91123456 8

AutoZone will initially provide all store numbers and addresses for the vendor's system records on diskette and will update this information via electronic fax, e-mail, or internet. AutoZone and the vendor will negotiate the latest daily pick-up time by the carrier from the vendor. Shipping Option Codes sent in Purchase orders: F01- priority overnight with Saturday delivery (air), F06 Standard Overnight (air); F11-Economy 2-day (air); R02-Ground. 2.6 Tracing Undelivered Parts AutoZone will be responsible for initially tracing a missing order. AutoZone stores will lookup the PO number for the unreceived part on their computer to obtain the carrier name and tracking number. Stores with Internet access will log onto the carrier web site to determine the estimated time of arrival (ETA). Stores without Internet access can call the carrier to obtain the ETA. The information the stores will use comes from the shipping quantity and the carrier's airbill number, found on the vendor's ASN. If a shipping error is found, e.g., the part was shipped to the wrong store, the receiving store will report it to the AutoZone store operations support line. The receiving store will then return the part to the vendor following their normal return policy, unless otherwise specified. 2.7 Shipping Errors Vendors who ship parts to the wrong store will be responsible for any costs incurred to correct the shipping error. AutoZone will not pay an invoice for parts when delivery is made to the wrong store. AutoZone will only pay one invoice for the correct shipment to the correct store. 2.8 Returns AutoZone stores will follow their normal return procedures. Defective, damaged, and undamaged returns will be properly tagged and returned to the store's warehouse. The warehouse will return the part to the vendor according to specific guidelines as described in the vendor agreement. Arrangements may need to be made by the vendor and AutoZone product manager to handle a possible increase in returns, i.e., AutoZone currently may be returning parts to a local warehouse that is not set up to handle additional returned parts. 9

2.9 Invoices AutoZone will process vendor invoices promptly when it can match the carrier's airbill number to the AutoZone purchase order number to the store that ordered the part. Invoices can only be paid when these three pieces of information can be matched in the AutoZone PO system. To track multiple unpaid invoices, vendors should send a diskette to one of the contacts listed in Section 3.2, Invoices and Payments. The information on the diskette must be in the following format: Invoice up to 22 characters, left justified PO Numeric (8 digits) Airbill Numeric (12 digits) Invoice Date Characters yyyy-mm-dd Store # Numeric (4 digits) Amount -999999999.99 Comments Field Numeric (16 digits)-store #/PO# Additional information or fields may be added at the end of the Comments field. 2.10 Vendor Holidays All VDP program vendors must notify AutoZone in writing of any holidays or factory closings a minimum of 30 days in advance of the closing date. AutoZone will inform all stores about any changes in vendor shipment dates and times. 10

2.11 Non-Compliance VDP is an AutoZone proprietary program. Appropriate actions per the VDP program agreement found in Section 5, including removal of the vendor from the VDP program, may be taken if any of the following situations occur: 1. The participating vendor or his employees share this program or program information with any other vendor or company. Such a breach would violate the existing confidentiality agreement between AutoZone and the vendor. 2. The vendor does not provide and maintain a dedicated phone line when an automated shipping system is used, or violates the carrier agreement. 3. The vendor continually ships to the wrong store. 4. The vendor is unable to provide timely and accurate EDI transmissions. 5. The vendor does not send accurate ASNs consistently or on a timely basis. 2.12 Vendor Agreements All existing vendor agreements remain in force and cannot be superceded by these guidelines. The required VDP program agreement, which includes a section regarding confidentiality, is provided in this document. All vendors participating in AutoZone's VDP program will be required to complete and return an original of this agreement prior to program start. Vendors must have a signed confidentiality agreement on file with AutoZone. Signed agreements should be sent to: Anita Merritt -- Merchandising Department 9009 AutoZone Parts, Inc. PO Box 2198 123 S. Front Street Memphis, TN 38101 11
