TERMS AND CONDITIONS

TERMS: A 5% DISCOUNT WILL BE ALLOWED ON ALL MONTHLY CHARGE PURCHASES OF
$200.00 OR MORE IF PAID IN FULL BY THE 10TH OF THE MONTH, AND CASH PURCHASES OF
$500.00 OR MORE EXCEPT ON VISA, MASTERCARD AND DISCOVER CREDIT CARD SALES.
Accounts not paid by the 20th are subject to Credit Hold classification unless prior arrangements have
been made with the Credit Manager. Accounts placed on Credit Hold must pay account in full PLUS a
service charge for accounts more than 30 days old and have reopening approval by the Credit Manager
before again being placed on open account.

A late charge, designated SERVICE/FINANCE CHARGE, may be charged on all past due accounts. This
charge will be computed on the basis of the maximum rates allowed by the state in which the charge is
applicable.

A thirty dollar ($30.00) charge will be made for all purchase checks returned to Locke Supply Company.
Discount will not be allowed on payment on account if the check is returned by the bank. We close our
books on the 25th of each month; therefore you can buy materials on the 26th of the month and have ap-
proximately 45 days before payment is due. (Example: Books close June 25th; you purchased material
June 26th; Payment is due on or by the 10th of August.)

All stores honor VISA, Mastercard and Discover credit cards. Purchases by credit card (VISA/Master-
card and Discover) will not be allowed a 5% discount. Payment of account balances by credit card is not
per-mitted. We have to pay the credit card companies extra for their services.

No future dating or delayed invoicing on merchandise is allowed.

All merchandise returned with our permission must be accompanied with the original purchase invoice and
be in resalable condition.

Any deviations or changes from the above shall be made by the Credit Manager only, and only for the
period of time he may designate.

MERCHANDISE: All merchandise is guaranteed to be first quality unless otherwise specified. Our liabil-
ity for defective material is limited to the cost of merchandise and to warranties of the manufacturer. (All
warranties are Limited Warranties. See manufacturers’ warranties for specifics.) We will not be liable for
any labor costs or damages incurred in the use of products sold by us. Our responsibility for condition of
goods ceases when accepted by the carrier or as it leaves our warehouse, or upon receipt by customer.

We cannot be responsible for material shortage claims for deliveries at unattended sites. Any claims must
be made within 24 hours from date of delivery.

DELAYS: We shall not be liable for delays occasioned by strikes, fires, accidents, failure to obtain materi-

RETURNED GOODS POLICY: Material can only be returned after prior approval has been granted
unless we have made an error in shipment. Other expenses connected with our receiving and handling
returned merchandise may also be charged to the customer (such as crating, freight or manufacturer’s
return charges). These charges do not apply to materials in warranty that are considered defective. No
merchandise may be returned for cash or credit after 30 days from date of purchase.
