Pursuant to a Master Sales Agreement that the Company entered into with OYO Corporation before its initial public offering, the Company and OYO Corporation purchase products from one another at scheduled discounts of 5% to 20% off the sellerŐs list prices. In addition, OYO Corporation purchases printhead-related products from other Japanese corporations and then resells those products to the Company.
