WARRANTIES OF MERCHANTABILITY AND FITNESS FOR PARTICULAR PURPOSE, RELATED TO
THIS AGREEMENT, AND THE WARRANTIES IN THE 1980 U.N. CONVENTION ON AGREEMENTS FOR
THE INTERNATIONAL SALES OF GOODS, THE UNIFORM COMMERCIAL CODE AND OTHER RELEVANT
LAWS SHALL NOT APPLY. WITH THE EXCLUSION OF GROSS NEGLIGENCE AND WILLFUL
MISCONDUCT, NEITHER OF THE PARTIES SHALL BE SUBJECT TO ANY CONSEQUENTIAL OR
INDIRECT DAMAGES WITH RESPECT TO CLAIMS MADE HEREUNDER OR BY ANY PURCHASER OR
USER OF THE PRODUCT.

12. INDEMNIFICATION

12.1. INDEMNIFICATION BY LICENSEE. Licensee will indemnify,
defend and hold Licensor and its directors, officers, employees, agents and
Affiliates harmless from and against any liabilities, damages, costs or
expenses, including reasonable attorneys' fees (collectively, "Losses"), which
arise out of, relate to or result from the breach by Licensee of any of its
representations, warranties or obligations contained within this Agreement or
any claim or action arising from, relating to or in connection with the
manufacture of the Product delivered from or on behalf of the Licensee.
Notwithstanding the foregoing, Licensee will not indemnify Licensor for any
Losses to the extent that Licensee is entitled to seek indemnification from
Licensor for such Losses under Section 12.2 of this Agreement.

12.2. INDEMNIFICATION BY LICENSOR. Licensor will indemnify,
defend and hold Licensee and its directors, officers, employees, agents and
Affiliates harmless from and against any Losses which arise from any claim,
lawsuit or other action to the extent such Losses arise out of, relate to or
result from the breach by Licensor of any of its representations, warranties or
obligations contained within this Agreement or any claim or action arising from
or relating in connection with the manufacture of the Product delivered from or
on behalf of Licensor. Notwithstanding the foregoing, Licensor will not
indemnify Licensee for any Losses to the extent that Licensor is entitled to
seek indemnification from Licensee for such Losses under Section 12.1 of this
Agreement.

12.3. INDEMNIFICATION PROCEDURES. A Party which intends to
claim indemnification under Section 12.1 or 12.2 of this Agreement (the
"Indemnitee") will promptly notify the other Party (the "Indemnitor") in writing
of any claim, lawsuit or other action in respect of which the Indemnitee or any
of its directors, officers, employees, and Affiliates intend to claim such
indemnification within a reasonable period of time after the assertion of such
claim; provided, however, that the failure to provide written notice of such

CONFIDENTIAL TREATMENT REQUESTED

claim within a reasonable period of time will not relieve the Indemnitor of any
of its obligations hereunder, except to the extent that the Indemnitor is
prejudiced by such failure to provide prompt notice. The Indemnitor will have
the right to assume the complete control of the defense, compromise or
settlement of any such claim with the prior written consent of such Indemnitee,
which such consent will not be unreasonably withheld; provided, however, that
Indemnitee will have the right to withhold such consent in its sole discretion
if such defense, compromise or settlement includes any admission of wrongdoing
on the part of an Indemnitee, or limits the scope of any claims in or
enforceability of any Patents owned by or licensed to the Indemnitee. The
Indemnitor may at its own expense, employ legal counsel to defend the claim at
issue. At any time after Indemnitor has assumed defense of a claim, the
Indemnitor may exercise, on behalf of the Indemnitee, any rights which may
mitigate the extent or amount of such claim; provided, however, the Indemnitee:
(a) may, in its sole discretion and at its own expense, employ legal counsel to
represent it (in addition to the legal counsel employed by the Indemnitor) in
any such matter, and in such event legal counsel selected by the Indemnitee will
be required to confer and cooperate with such counsel of the Indemnitor in such
defense, compromise or settlement for the purpose of informing and sharing
information with the Indemnitor; (b) will, at its own expense, make available to
Indemnitor those employees, officers and directors of Indemnitee whose
assistance, testimony or presence is necessary, useful or appropriate to assist
the Indemnitor in evaluating and in defending any such claim; provided, however,
that any such access will be conducted in such a manner as not to interfere
unreasonably with the operations of the businesses of Indemnitee; and (c) will
otherwise fully cooperate with the Indemnitor and its legal counsel in the
investigation and defense of such claim. The rights and remedies provided
pursuant to this Section 12 are the sole and exclusive remedies of the Parties
hereto with respect to Losses.

12.4. INSURANCE. Each Party will make best efforts, assuming
its availability, to maintain commercially reasonable insurance coverage
commensurate with its obligations under this Agreement. Such commercially
reasonable insurance coverage will include comprehensive general liability
insurance coverage, including product liability, preferably with a minimum limit
of not less than [CONFIDENTIAL TREATMENT REQUESTED], or the highest available
limit, which shall be in effect at initiation of any Clinical Trials in the
Territory.

13. TERM AND TERMINATION

13.1. TERM OF THE AGREEMENT. The term of this Agreement (the
"Term") will commence on the Effective Date and, unless terminated earlier
pursuant to this Section 13, will expire on a country-by-country basis upon the
later of (a) the expiration of an issued Licensed Patent covering the Product in
a given country in the Territory, or (b) the date 10 years after the date of
First Commercial Sale of a Product in such country in the Territory under this
Agreement.

13.2. LICENSEE'S RIGHT TO TERMINATE. Licensee may terminate
the Agreement (a) in any country within the Territory with service of thirty
(30) Business Days written notice if: 1) the Product is considered unsafe by the
SFDA, or other applicable regulatory authorities, to administer to patients; or
2) Licensor is unable to manufacture and supply the Product to Licensee to meet
Licensee's demand after Licensor receives notice from Licensee to that effect
and after a 30 day opportunity to cure its failure to meet Licensee's
manufacture and supply demands; and (b) after the First Commercial Sale of the
Product in any country within the Territory with service of 3 months written

CONFIDENTIAL TREATMENT REQUESTED

notice. In the case of termination pursuant to 13.2 (a), the Parties will make
all reasonable attempts to solve any safety or supply problems before Licensee
terminates the Agreement. If Licensee terminates the Agreement for any reason
other than those stated in 13.2(a), 13.3 or 13.4 (i.e. change of control or
strategy), the Parties agree to negotiate in good faith to find a solution which
will allow product development to continue in the Territory.

13.3. TERMINATION FOR MATERIAL BREACH. In the event of a
material breach of this Agreement by either Party, which is not cured within
sixty (60) Business Days following receipt of written notice of the such breach
from the non-breaching Party, the non-breaching Party will have the right to
terminate this Agreement by written notification to the other Party, effective
immediately upon receipt.

13.4. TERMINATION FOR BANKRUPTCY. Either Party may immediately
terminate this Agreement upon the occurrence of either of the following: (a) the
entry of a decree or order for relief by a court having jurisdiction in the

applicable national, federal, or state insolvency or other similar law, and the
continuance of any such decree or order unstayed and in effect for a period of
sixty (60) consecutive days; or (b) the filing by the other Party of a petition
for relief under any applicable national, federal, or state insolvency or other
similar law.

14. CONSEQUENCES OF TERMINATION

14.1. GENERAL. No termination of this Agreement will relieve
any Party hereto from any liability which, at the time of such termination, has
already accrued to the other Party or which is attributable to a period prior to
such termination, nor preclude either Party from pursuing any rights and
remedies it may have under this Agreement or at law or in equity which accrued
or are based upon any event occurring prior to such termination.

14.2. TERMINATION UNDER 13.2. In the event of termination by
Licensee of this Agreement under Section 13.2, Licensee shall forthwith after
the effective date of termination:

14.2.1 provide to Licensor the Dossier, all Product and
Scientific Data and any other documents, materials, data or information within
Licensee's possession or control containing or evidencing any Intellectual
Property of Licensor and all Licensor Confidential Information and:

14.2.2 cease all exploitation, manufacturing and marketing of
Product provided always that Licensee shall be entitled to continue to sell
Product for a period of six calendar months thereafter in order to fulfill
existing orders only (subject always to payment of Royalties) and provided that
Licensee shall not sell such inventory in a manner detrimental to the market for
Product in the Territory;

14.2.3 upon termination under sub section 13.2(b), give or
procure for Licensor access to all data filed in connection with the Marketing

all reasonable endeavors to effect an orderly transfer to Licensor of the
management and conduct of the Clinical Trials performed by or on behalf of
Licensee and to fulfill Third Party obligations related to the Clinical Trials,
including requirements of authorities, ethical committees etc.

14.3. LICENSOR'S TERMINATION UNDER 13.3. In the event of

material breach, Licensee shall perform the acts set out in subsection 14.2

Licensee's termination under subsection 13.4 of this Agreement due to Licensor's
bankruptcy, Licensee's rights shall continue in full force in the Territory and
shall not be affected by any proceedings. If Licensor is responsible for
manufacture and supply of Product to Licensee, Licensee shall have the right to
obtain its supply of Product from Licensor's Third Party contract manufacturer
with no obligation to Licensor. Licensor shall immediately transfer to Licensee
any necessary manufacturing technology and Know-How. All Licensed Patents shall
become automatically assigned to Licensee and Licensor agrees to effect such
assignment. Licensee will have no further obligations to make royalty and
milestone payments due under the Agreement except for royalties and other
payments due prior to the date of Licensor's petition for bankruptcy.

14.5. LICENSOR'S TERMINATION UNDER 13.4. In the event of
Licensor's termination under subsection 13.4 of this Agreement to Licensee's
bankruptcy, Licensee shall perform the acts set out in subsection 14.2 above.

Agreement pursuant to Section 13.1 of this Agreement with respect to a country

Confidential Information and will not disclose the same to any other person,
firm or corporation, except as allowed hereunder. Notwithstanding the foregoing,
the obligation of confidentiality contained in this Agreement will not apply to
the extent that the receiving Party can demonstrate, by competent written proof,

that during the term of this Agreement and for ten (10) years after its
expiration or termination for any reason whatsoever, a Party receiving
Confidential Information of the other Party will: (a) treat any such
Confidential Information disclosed to it by the other Party as strictly
confidential; (b) except as necessary in the performance of this Agreement, not
disclose such Confidential Information to Third Parties without the prior
written consent of the other Party, other than to its Affiliates, sublicensees,
collaborators or any consultants, provided that such disclosure be under
confidentiality agreements with provisions comparable to those contained in this
Agreement; (c) not use such Confidential Information for purposes other than
those authorized expressly herein; and (d) use reasonable efforts to prevent
inadvertent disclosure of such Confidential Information, provided however, that
the obligations under this Section 15.2 shall continue in force and effect with
respect to each item of Confidential Information that is identified as a trade
secret by the disclosing party at the time of or within thirty (30 ) days after
its initial disclosure hereunder, until such time as such item of Confidential
Information is no longer susceptible of being kept a trade secret.

15.3. ACCESS. Access to Confidential Information will be
limited to those employees or consultants of the Party designated to receive
such information or of such Party's Affiliates who reasonably require such
information in order to carry out activities authorized pursuant to this
Agreement. Such employees or consultants will be advised of the confidential
nature of the Confidential Information and the related confidentiality
undertaking and each Party will assure that its employees, consultants and
Affiliates are bound by the terms of this Agreement relating to confidentiality.

15.4. PERMITTED DISCLOSURES. Notwithstanding any other
provision in this Agreement, a receiving Party may disclose Confidential
Information of the disclosing Party to the extent such disclosure is required by
law or court order, provided that the receiving Party gives the disclosing Party
prompt written notice of the requirement to disclose and reasonably cooperates
with the disclosing Party to seek a protective order or other restrictions on
the disclosure of such Confidential Information of the disclosing Party. Any

CONFIDENTIAL TREATMENT REQUESTED

such required disclosure will be limited only to that Confidential Information
that is required to be disclosed and such disclosed Confidential Information
will remain Confidential Information hereunder despite the required disclosure.
A receiving Party may also disclose Confidential Information of the disclosing
Party in connection with filing, prosecuting, defending and/or enforcing
Patents, seeking or maintaining Marketing Authorizations and developing Product.

15.5. RETURN OF CONFIDENTIAL INFORMATION. Upon termination or
expiration of this Agreement, each Party hereto and its Affiliates will return

determining the extent of disclosure of Confidential Information hereunder and
assuring compliance with the surviving provisions of this Agreement; (b) any
portion of the Confidential Information of the other Party which is contained in
laboratory notebooks; and (c) any portion of the Confidential Information of the
other Party which a Party is required by mandatory applicable law to retain.

disclose the terms of this Agreement to actual or prospective investors and
corporate partners (including sublicensees), to a Party's accountants, attorneys

research results arising from this Agreement will be submitted to the other
Party at least twenty five (25) Business Days prior to submission for

twenty five (25) Business Day period for publication submissions and ten (10)
Business Day period for abstracts or oral, or other non-written format,
disclosures, the reviewing Party shall identify information that in the
reasonable judgment of such Party (a) will interfere with such Party's rights
hereunder (including any effect on patentability of disclosed information)
and/or (b) constitutes such Party's Confidential Information. Should the
reviewing Party require additional time to conduct its review the submitting
Party agrees to postpone the oral disclosure and submission of the manuscript or
the abstract for up to an additional sixty (60) days. Each Party agrees to
delete from any proposed manuscript, abstract or oral disclosure, information
identified by the other Party as its Confidential Information.

announcement concerning the existence, or the terms, of this Agreement, without
the prior written approval of the other Party with regard to the form, content

made by either Party in order to comply with applicable law, regulations, court
order, or tax or securities filings. A Party disclosing under the above
provision according to law shall provide the other Party with a copy of the
disclosed information. Such consent will not be unreasonably withheld or delayed
by such other Party. Prior to any such public announcement, the Party wishing to
make the announcement will submit a draft of the proposed announcement to the
other Party as soon as possible and in no event less than five (5) Business Days
in advance to enable the other Party to consider and comment thereon.
Notwithstanding anything to the contrary in this Agreement, nothing in this
Section 15.8 is intended to prohibit either Party from republishing or restating
information relating to this Agreement that has already been approved by the
other Party for use in a prior press release or public announcement.

16. PERFORMANCE BY AFFILIATES

The Parties recognize that each Party may perform some or all of its
obligations under this Agreement through Affiliates, provided, however, that
each Party will remain responsible for the performance by its Affiliates and

connection with such performance and any act or omission committed by an
Affiliate shall be deemed to have been conducted by the Party itself.

17. DISPUTE RESOLUTION

17.1. The Parties will try to settle their differences
amicably between themselves. In the event of any controversy or claim arising
out of or relating to any provision of this Agreement or the performance or

Dispute that is not resolved as provided in the preceding Section 17.1, whether
before or after termination of this Agreement, that in any way relates to the
Agreement, will be arbitrated pursuant to the Singapore Arbitration Act of 2001
(the "Rules") by three (3) independent and impartial arbitrators in accordance
with said Rules, but the Parties may agree on just one arbitrator. The
arbitration will be conducted in English and will be held in Singapore and each
Party will pay for their own costs and the cost of the arbitrators will be
divided equally among the Parties. The award in the arbitration will be final
and enforceable in any court of competent jurisdiction.

CONFIDENTIAL TREATMENT REQUESTED

18.2. ASSIGNMENT. Neither Party will assign its rights or
obligations under this Agreement to any Third Party without the prior written
consent of the other Party (which consent shall not be unreasonably withheld),
except that either Party may assign such rights and obligations, without
consent, to the surviving entity pursuant to a merger, acquisition or
consolidation, or to a Third Party acquiring all or substantially all assets of
a Party. In the event of such a transaction, however, intellectual property of
the acquiring entity shall not be included in the Licensed Technology. All
permitted assignments by either Party of any of its rights under this Agreement
will be subject to all of the terms and conditions of this Agreement. All
successors, permitted Licensees of either Party will be subject to, and will be
bound in writing by, all the terms and conditions of this Agreement. Any
purported assignment not permitted under the terms of this Agreement will be
null, void, and of no effect.

18.3. INDEPENDENT CONTRACTORS. The Parties hereto are
independent contractors. Nothing contained herein will constitute either Party
the agent of the other Party for any purpose whatsoever, or constitute the
Parties as partners or joint ventures. Employees of each Party remain employees
of said Party and will be considered at no time agents of or owing a fiduciary
duty to the other Party. Neither Party hereto will have any implied right or
authority to assume or create any obligations on behalf of or in the name of the
other Party or to bind the other Party to any other contract, agreement or
undertaking with any Third Party.

18.4. WAIVER. The failure of either Party to enforce any
provision of this Agreement at any time will not be construed as a present or
future waiver of such or any other provision of this Agreement. The express
waiver by either Party of any provision or requirement hereunder will not
operate as a future waiver of such or any other provision or requirement and
will be effective only if set forth in a written instrument signed by a duly
authorized representative of the Party waiving such provision or requirement.

18.5. AMENDMENT. The Parties hereto may amend, modify or alter
any of the provisions of this Agreement, but such amendment, modification or
alteration will be valid and binding on either Party only if made by a written
instrument that explicitly refers to this Agreement and that is signed by a duly
authorized representative of each Party.

18.6. SEVERABILITY. In the event that any provision in this
Agreement is held to be unlawful or invalid in any jurisdiction, the meaning of
such provision will be construed to the greatest extent possible so as to render
it enforceable. If no such construction can render such provision enforceable,
it will be severed. The remainder of this Agreement will remain in full force
and effect, and the Parties will negotiate in good faith a reasonable substitute
provision that is valid and enforceable in such jurisdiction. If the Parties are
unable to agree on a substitute provision, and if the unlawful or invalid
provision was an essential element of this Agreement without which one of the
Parties would not have entered into this Agreement, as evidenced by this
Agreement as a whole, then such Party may terminate this Agreement by written
notice to the other Party effective upon receipt.
