this Agreement.

8.13B  Upon written notice to Licensee, Licensor may from time to time alter the

ARTICLE 9. TERM & TERMINATION

9.01  This Agreement shall be effective for the period of [*] commencing on the
Effective Date unless earlier terminated pursuant to the provisions of this
Agreement, and after expiration of the original term, this Agreement may be
renewed by the mutual written consent of the parties hereto under the terms and
conditions to be then mutually agreed upon and subject to the approval of the
Japanese Government, if then required. Notwithstanding the foregoing in this
Article 9.01, in the event Licensee continues the manufacture of the Products

conditions, unless Licensor gives a notice of termination at least [*] prior to
the expiration of any renewal term.

9.02  If at any time during the term of this Agreement, Licensee makes any

writing to Licensee. No failure or delay on the part of Licensor to exercise its

control of Licensee and/or Sub-Licensee as, in the opinion of Licensor, may

political, economic or taxation policy by the governmental or quasi-governmental

within [*] from the Effective Date hereof; or
(h) the sub-licensing arrangement between Licensee and Sub-Licensee is not

Regulations without the required approval of the [*] Government to the extent
required.

D.  Licensee and Sub-Licensee shall not knowingly sell, lease or otherwise

Licensor shall have the right to terminate this Agreement forthwith by giving a
written notice to Licensee, without any prejudice to the rights and remedies
which Licensor may have under this Agreement.

G.  In the course of operation under this Agreement, Licensor may wish to obtain
from Licensee, technical data, whether by direct communication between Licensee
and Licensor, or by communication between Licensee and employees of Licensor who
are not U.S. citizens, but who are assigned to Licensee by Licensor. To the
extent that any such technical data is subject to U.S. export controls and may
not be exported except with prior receipt of a Letter of Assurances, this
Agreement is intended to serve as such Assurances. Licensor assures that it will
not re-export, re-transfer or otherwise release any such data or the direct
product thereof except in conformity with the then applicable U.S. export
control laws and regulations. As used in this Article 10.02, the terms

ARTICLE 11. SEVERABILITY

11.01  If any provision(s) of this Agreement shall contravene any laws or
regulations, it is agreed that the invalidity or illegality of such provision(s)
shall not invalidate the whole of this Agreement but this Agreement shall be
construed as if it did not contain the provision(s) claimed or held to be
invalid or illegal in the particular jurisdiction concerned insofar as such
construction does not effect the substance of this Agreement, and the rights and
obligations of the parties hereto shall be construed and enforced accordingly.
In the event, however, that such claim of invalidity or illegality shall
substantially and adversely effect the interest of either party hereto, the
parties hereto shall negotiate a mutually acceptable provision(s) not
conflicting with such laws, and, if the parties hereto cannot agree upon a
substitute provision(s) within a reasonable period, Licensor or Licensee may
terminate this Agreement forthwith.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement in two (2)
original counterpart instruments, to be executed and delivered in English, as of
the date written below, by their duly authorized officers.
