 ARTICLE
4  LICENSE AND TRANSFER OF TECHNOLOGY
 4.1
    
    LICENSORS hereby grant to LICENSEE and LICENSEE hereby accepts from LICENSORS, upon the terms
and conditions herein specified, an exclusive, royalty-bearing license in the TERRITORY, with
the right to grant sublicenses, under the TECHNOLOGY and PATENT RIGHTS, subject to U.S.
Government rights in the TECHNOLOGY, to make and have made, use and have used, and sell and
have sold, LICENSED PRODUCTS for use in the FIELD. In recognition of the general applicability
to other drugs of MVPs technology for the production of PEG conjugates of uricases, BTG
expressly agrees that it shall not utilize such technology in any manner except for the
production of PEG conjugates of uricases and only as provided in this AGREEMENT; provided,
however, that MVP expressly agrees that nothing contained in this AGREEMENT shall be read to
preclude LICENSEE from using technology for the production of PEG conjugates which is in the
public domain, or which is developed by LICENSEE independent of MVPs technology for the
production of PEG conjugates, or which LICENSEE acquires or licenses from a third party.
 4.2
    
    Within sixty (60) days after the execution of this AGREEMENT:

Number 2, page TM 100) and is pending in the European Community (Application No. 716019).

(a)
    
    LICENSEE may use whichever trademark or trademarks it may elect, in its sole
discretion, in connection with the marketing of LICENSED PRODUCTS, and shall be under
no obligation to use the trademark, PURICASETM.(b)
    
    If LICENSEE elects not to use the trademark PURICASETM or otherwise
fails to use such trademark by one (1) year after the first sale of any LICENSED
PRODUCT, MVP shall retain all rights to its use.
 4.4
    
    LICENSEE shall comply with all obligations imposed by the U.S. Government on exclusive
licenses of inventions made under a U.S. Government funding agreement including, but not
limited to, the requirement that any products which are sold in the United States be
substantially manufactured in the United States, if such products are based on inventions
conceived or first actually reduced to practice under such funding agreements.
 (a)
    
    LICENSORS recognize that the currently projected market for LICENSED PRODUCTS
does not justify a second manufacturing facility, and that LICENSEE currently has a
manufacturing facility in Israel, and, therefore, LICENSORS and LICENSEE agree to
cooperate and use their best efforts to promptly obtain a waiver of the U.S.
manufacturing requirement.(b)
    
    DUKE represents that PBC URICASE was constructed at DUKE prior to its receipt
of the GRANT and that U.S. Government funds did not support its development; and
represents further that subject to review and determination by DUKE, other uricases may
also have been constructed at DUKE prior to its receipt of the GRANT, developed without
the support of U.S. Government funds, and that DUKE shall promptly identify any such
uricases for LICENSEE.
 4.5
    
    Any sublicenses granted by LICENSEE shall be on such financial terms as LICENSEE may
negotiate in its sole discretion but otherwise shall be subject to, and shall incorporate
therein, conditions at least as stringent as those imposed on LICENSEE by the terms of this
AGREEMENT.
 (a)
    
    LICENSEE agrees to be responsible for any obligations assumed hereunder by its
sublicensees.(b)
    
    LICENSEE further agrees that all sublicense agreements will provide that if
LICENSORS terminate this AGREEMENT pursuant to Section 10.3 or 10.6 prior to the end of
the TERM in one or more countries, or if LICENSEE terminates this AGREEMENT pursuant to
Section 10.2, all such sublicenses in those countries shall be assigned directly to
LICENSORS; provided, however, that LICENSORS first agree, in writing, to assume all of
LICENSEEs obligations under such sublicenses and to hold LICENSEE harmless with
respect to any claims made by such sublicensees as a result of such termination;
provided, however, that LICENSORS shall not be liable for any claims against LICENSEE
arising out of LICENSEEs negligence or willful wrongdoing, or claims arising from
LICENSEEs breach, prior to termination, of its obligations under a sublicense.(c)
    
    LICENSORS shall promptly be provided a copy of each sublicense agreement,
provided, however, that during the TERM of this AGREEMENT, LICENSORS shall maintain
such agreements in confidence and shall not contact any such sublicensee without
LICENSEEs prior written consent.

the version of the patent application (titled PEG-URATE OXIDASE CONJUGATES AND USE THEREOF)
that has been filed with the United States Patent and Trademark Office, then:
 (a)
    
    If upon such review subsequent to execution of this AGREEMENT, which LICENSEE
shall complete within sixty (60) days after receipt of such application, LICENSEE
determines in good faith that such application is inadequate (e.g.,for lack of support
in the specification or in view of the prior art), LICENSEE may elect, in its sole
discretion, to terminate this AGREEMENT.(b)
    
    If LICENSEE does so elect to terminate, MVP and DUKE shall each refund to
LICENSEE all payments made to them by LICENSEE as of the date of termination, and MVP
shall be solely responsible for the repayment to BIRD, should such repayment be
required, of any funds received by MVP from BIRD.
 5.6
    
    MVP shall commence the transfer to BTG of its proprietary

    MVP and DUKE have been notified, in writing, by BTG following the review of
their patent application as set forth in Section 5.5, either that such patent
application is acceptable or, if unacceptable, that BTG nonetheless elects not to
terminate the AGREEMENT, and that, therefore, the payments made by BTG to MVP and DUKE
as of the date of such written notice are irrevocable;(b)
    
    BTG and MVP have selected a specific uricase and BTG has provided at least [**]
from a single batch to MVP for each [**] of PEG conjugate to be prepared by MVP as part
of the technology transfer; and(c)
    
    BTG has installed at its facility in Israel all of the necessary instruments,
accessories, columns and other materials for assessing the activity of uricase, the
purity of the PEG-uricase conjugates and the number of strands of PEG attached per
uricase subunit according to MVPs protocols. [**]

    The technology transfer shall include the following steps: [**]5.9
    
    BTG and MVP shall use their best efforts to complete successful transfer of such technology
as promptly as possible and each company shall therefore assign appropriately skilled

    that payments 2) in Section 5.1 shall have been made;(b)
    
    that such manufacturer shall first agree to maintain such technology in
confidence on terms no less restrictive than those applicable to LICENSEE under this

PARTY may, at its option and in addition to any other remedies it may have in law or in
equity, terminate this AGREEMENT for
