granted herein; provided, however, that Licensor shall have the right, upon
notice to Licensee, to withdraw from the Territory any country in which a third
party claims that Licensee's use of the Marks or the URLs is an infringement or
violation of such third party's rights, provided, that Licensee shall have the
right to continue to use the Marks or the URLs if Licensee agrees in writing to
indemnify and defend and hold harmless Licensor from all liability, damages,
loss, cost or expense (including but not limited to reasonable attorneys' fees
and expenses) arising from Licensee's continued use of the Marks or the URLs in
such country.

                              TRADEMARK GUIDELINES

              All terms used in this Exhibit B that are defined in the Agreement
shall have the meaning ascribed to them in the Agreement.

              1.     The Marks licensed under the Agreement (i.e., the "ZDU"
word mark and the "ZDU" logo) shall be used strictly in accordance with the
specifications set forth in the Agreement and below.

              2.     The Marks shall be used only as a composite mark and shall
be used only in the exact form and manner used by Seller in connection with the
Business prior to the execution of the Agreement.

              3.     The Marks shall not be enclosed in any way by a border or
combined with or incorporated with or in any other words or marks, or modified
in any other way. The Marks shall be of sufficient size and on an appropriately
contrasting background to make all letters plainly legible.

              4.     The Marks shall be used only in accordance with the
specifications as to placement, size and design set forth herein and always be
used in one of the following two color choices:

100% Black
PMS 485 Red plus Black

              5.     Seller shall provide Buyer with stats for the ZDU logo for
the uses permitted under the Agreement, and Buyer shall use only those stats in
exercising its rights under the Agreement.

              6.     The Marks shall always be written in a distinctive fashion,
e.g.,

              (i)    ZDU (all caps)

              (iii)  ZDU (bold)

<PAGE>   10


              7.     Buyer will use commercially diligent efforts to use the
Marks only as an adjective followed by the common generic term for the mark,
e.g., the "ZDU courseware" and shall not use the Marks in the possessive.

              8.     Whenever reasonable in the context of a particular use of
the Marks, Buyer shall identify such trademark as being used under license from
Seller.

              9.     Each of the Marks must include the (R) or (TM) symbol, as
designated by Seller, and the following notice: "ZDU and the ZDU logo are either
registered trademarks or trademarks of ZD Inc. in the United States and/or other
countries".

              The guidelines numbered 1-9 above may be amended by Seller in its
sole discretion from time to time upon written notice to Buyer.
