     14.2 It is understood that by the time of the expiration of this Agreement,
Schein intends to re-establish its own manufacturing site for Product and that
both parties intend to obtain a new FDA-approved source for Raw Material. Given
the uncertainty of these efforts, however, the following additional options to
extend the initial term of the Agreement are provided:

          14.2.1 Schein shall have the option to extend this Agreement and all
its provisions for up to two additional six-month extension periods by giving
Pfizer written notice of such extension at least ninety (90) days prior to
expiration of the initial term or the first extension thereto.

          14.2.2 Pfizer shall have the option to extend this Agreement and all
its provisions relating to the supply by Schein of Pfizer's requirements for Raw
Material for the manufacture by Pfizer of Pfizer Product for up to four
additional six-month extension periods by giving Schein written notice at least
sixty (60) days prior to the expiration of the initial term of any extensions
thereto.

     14.3 Either party will have the right to terminate this Agreement if the
other party fails to remedy any material breach of this Agreement within sixty
days of written notice of such breach.

     14.4 The terms and provisions of Section 6.1, 6.2, 7.1, 7.2, 7.3, 12.0 and
13.0 shall survive the term and termination of this Agreement.
