days prior KONICA's -First Commercial Shipment of the Authorized KONICA Device.
At such time, KONICA shall provide initial versions of any applicable PPD Files,
and any other checklists or specification information requested by PEERLESS.
Based on such information, PEERLESS will request that Adobe creates a test plan
specifying the testing to be performed by KONICA to meet Adobe's certification
criteria. If the Authorized KONICA Device that contains the Licensed Products is
one of a family of products with substantially similar functionality and
features, Adobe may choose to identify a subset of these Authorized KONICA
Devices on which to perform testing for conformance with the acceptance
criteria.

3.2. KONICA Testing. Prior to submission of Authorized KONICA Device to Adobe

6.0 PROPRIETARY RIGHTS AND CONFIDENTIALITY

6.1 PEERLESS shall own all title and proprietary rights, including without

expressly granted to the KONICA hereunder are reserved by the PEERLESS.

Accordingly, KONICA has the right to develop its own modifications to the

manufacture and distribute such modified code (i.e., a Derivative Work) in
