Item 5. Other Events.
------------
On April 6, 1998, the Registrant finalized an Amendment to Restated
Patent Licence Agreement (the "U.S. Amendment") and an Amendment to Restated
Foreign Patent License Agreement (the "Foreign Amendment") with the American
Dental Association Health Foundation (the "ADAHF"), both of which are effective
as of January 1, 1998. The U.S. Amendment amends the Restated Patent License
Agreement, dated as of June 24, 1992, as amended by the Amendment Agreement
dated as of June 12, 1995 (together, the "License Agreement"), and the Foreign
Amendment amends the Restated Foreign Patent License Agreement, dated as of
November 18, 1992, as amended by the Foreign License Amendment Agreement, dated
as of June 14, 1995 (together, the "Foreign License Agreement").
The License Agreement, as amended by the U.S. Amendment (the "Amended
License Agreement"), grants the Registrant a fully-paid exclusive United States
license to manufacture and sell toothpastes and chewing gum and other food and
confectionery products ("Exclusive Products") using certain ADAHF patents issued
in the United States (the "ADAHF Patented Technology"). Under the Amended
License Agreement, the Registrant will be required to pay a fixed annual royalty
through 2008 of $400,000 with respect to all sales by the Registrant of
Exclusive Products (whether or not they rely upon the ADAHF Patented Technology)
up to $100 million in that year and an additional fixed royalty of $200,000 with
respect to all sales by the Registrant of Exclusive Products exceeding $100
million in that year. The term of the Amended License Agreement expires upon the
last to expire of the ADAHF patents licensed under the Amended License
Agreement, including any continuations, divisions, reexaminations, extensions or
releases thereof.
The Foreign License Agreement, as amended by the Foreign Amendment
(the "Amended Foreign License Agreement"), grants the Registrant a fully-paid
exclusive license to manufacture and sell Exclusive Products using technology
that is the subject matter of foreign patent applications filed by the ADAHF in
certain foreign countries. It also grants the Registrant the non-exclusive right
to manufacture and sell in such countries other products using that technology,
including oral sprays, mouth rinses and professional gels ("Non-Exclusive
Products"). The Amended Foreign License Agreement provides that the Registrant's
payment of royalties under the Amended License Agreement will constitute a
fully-paid license under the Amended Foreign License Agreement with respect to
sales of the Exclusive Products. The royalties payable with respect to sales of
Non-Exclusive Products and other provisions of the Foreign License Agreement
pertaining to Non-Exclusive Products remain unchanged under the Amended Foreign
License Agreement.
The U.S. Amendment and the Foreign Amendment each provides that the
Registrant may assign or sublicense its rights under its licenses with respect
to the Exclusive Products without the consent of the ADAHF, provided that the
Registrant will continue to remain liable for payment of royalties under the
Amended License Agreement. In addition, the ADAHF has waived any claim to
ownership rights in any of the Registrant's patents, and the Registrant has
agreed not to sue the ADAHF or any licensee of the ADAHF licensed to use the
ADAHF patents for infringement of the Registrant's patents, unless the
infringement constitutes a breach of the Registrant's exclusive license under
the two license agreements.
