6. TARCANTA and TARCANTA LTD. believe that conducting international
clinical trials in countries throughout the Territory, including the Other
Countries, will significantly advance their ability to obtain Regulatory
Approvals of the Licensed Products in the U.S. and throughout the Territory in a
timely manner by increasing the number and diversity of patients that may be
enrolled in clinical trials of the Licensed Products. Accordingly, TARCANTA,
TARCANTA LTD. and CIMAB agree to further develop the Licensed Products and
TARCANTA and TARCANTA LTD. agree to conduct clinical trials for the Licensed
Products and to obtain Regulatory Approvals that are necessary in order to
market and sell the Licensed Products in the Territory (as such terms are
defined below) in accordance with the terms and conditions of this Agreement.
For the purposes of this Agreement, all countries in the Territory other than
the U.S., Canada and Mexico shall be referred to herein as the "Other
Countries."

7. TARCANTA and TARCANTA LTD. agree, upon receipt of applicable Regulatory
Approvals, to manufacture, market and sell the Licensed Products in the U.S.,
Canada and Mexico.

8. Consistent with normal industry practices in a licensing arrangement of
this nature, and in an effort to advance the potential for making the Licensed
Products available for the treatment of cancer patients in the U.S. and
throughout the Territory, TARCANTA LTD. and TARCANTA agree, upon receipt of
applicable Regulatory Approvals, to market and sell the Licensed Products
purchased from CIMAB in the Other Countries, in accordance with the terms and
conditions of this Agreement.

9. In order to ensure an adequate supply of the Licensed Products for
clinical testing and, upon commercialization, for the treatment of patients in
the U.S. and throughout the Territory, TARCANTA and TARCANTA LTD. agree to
purchase the Licensed Products from CIMAB, and CIMAB agrees to manufacture and
sell such Licensed Products to TARCANTA and TARCANTA LTD., in accordance with
the terms and conditions of this Agreement.

10. Because the Parties believe that a more effective vaccine for the
treatment of some types of cancer may be created by the sequential use or the
combination of the EGF Vaccine with TGF-(alpha) and/or HER-1 Vaccines Controlled
By CIMAB, simultaneously with the execution of this Agreement, the Parties will
also enter into a certain TGF-(alpha) / HER-1 Vaccine License, Development and
Supply Agreement (the "TGF-(alpha) / HER-1 Agreement") with YM Biosciences,
Inc., a corporation organized under the laws of Nova Scotia, Canada, and CIMYM,
Inc., a corporation organized under the laws of Barbados, West Indies (which is
jointly owned by CIMAB and YM Biosciences for purposes of the development of the
TGF-(alpha) and HER-1 Vaccines), pursuant to which TARCANTA and TARCANTA LTD.
will further develop, conduct clinical trials, manufacture and sell the
TGF-(alpha) / HER-1 Vaccines (as such terms are defined therein) in the
Territory.

In consideration of the premises and of the mutual covenants and
obligations set forth herein, the Parties hereby agree as set forth below.

5.7.8 TARCANTA and TARCANTA LTD.'s transfer of funds to the Holding
Account as required by this Agreement or otherwise shall not constitute payment
to CIMAB or discharge of any of TARCANTA and/or TARCANTA LTD.'s obligations
under this Agreement to make payment to CIMAB (whether by payment for Barter
Goods or for Payment in Cash). The failure of the Escrowee to make payments for
Barter Goods or to CIMAB for Payments in Cash, shall not constitute any excuse
for TARCANTA or TARCANTA LTD.'s failure to make the payments required by this
Agreement.

5.8 Taxes and Withholding. All payments under this Agreement will be made
without any deduction or withholding for or on account of any tax unless such
deduction or withholding is required by Applicable Laws. If the paying Party is
so required to deduct or withhold, such Party will (i) promptly notify the other
Party of such requirement, (ii) pay to the relevant authorities the full amount
required to be deducted or withheld promptly upon the earlier of determining
that such deduction or withholding is required or receiving notice that such
amount has been assessed against the other Party, (iii) promptly forward to the
other Party an official receipt (or certified copy) or other documentation
reasonably acceptable to the other Party evidencing such payment to such
authorities.

5.9 Currency. All payments and calculations hereunder to CIMAB shall be in
Euros, in the case of Payment in Cash, in an amount equivalent to the amount due
in U.S. dollars at the exchange rate offered by the Bank of America on the date
upon which payment is due, provided, however, that in the event that CIMAB is
prevented from receiving payment in Euros by Applicable Laws, CIMAB may, during
the period when such laws are in effect, designate that all subsequent payments
shall be in another currency designated by CIMAB, provided further, however,
that such other currency shall not be any currency of Cuba. As applicable, Net
Sales and expenses incurred by either Party shall be translated into U.S.
dollars in accordance with TARCANTA's customary and usual translation
procedures, consistently applied., provided, however, that Net Sales received by
TARCANTA or TARCANTA LTD. in Euros shall not be translated into U.S. dollars,
but shall be paid as a percentage of Euros received in accordance with the terms
of this Agreement.

5.10 Payments

5.10.1 Payments in Cash. TARCANTA LTD. shall direct the Escrowee to
make the Payments in Cash from the Barter Escrow Account to CIMAB by wire
transfer of immediately available funds to an account at a bank in a Third
Country reasonably designated by CIMAB from time to time in writing. TARCANTA
LTD. shall so direct the Escrowee promptly upon the Barter Escrow Account
receiving funds to be used for Payments in Cash.

5.10.2 If any sum due and payable under this Agreement shall not
have been paid or, as applicable, deposited in the Holding Account or the Barter
Escrow Account, on or before the applicable due date, compound interest shall
accrue on the unpaid amount at the rate of one percent (1%) per month or, if
less, the maximum rate permitted under applicable law from the

payment due date, until the actual date of payment without prejudice to any
other claim or remedy available to the non-paying Party.

5.10.3 Payments into Barter Escrow Account. Where this Agreement
provides for Barter Payments, TARCANTA and/or TARCANTA LTD. shall be responsible
for all amounts due for payment into the Barter Escrow Account when due under
this Agreement, which shall be accomplished by either direct payment by TARCANTA
and/or TARCANTA LTD. into the Barter Escrow Account or by payment of the amount
due into the Barter Escrow Account by the Holding Account escrowee. The funds in
the Barter Escrow Account shall only be used to carry out CIMAB's purchase of
Barter Goods from U.S. sources or to make Payment in Cash to CIMAB, in
accordance with the terms of this Agreement. Whenever CIMAB intends to purchase
Barter Goods using the funds deposited in the Barter Escrow Account, CIMAB shall
provide the escrow agent at the bank at which the Barter Escrow Account is
maintained and TARCANTA and TARCANTA LTD. with a purchase order to a Third Party
supplier of Barter Goods that identifies the Barter Goods being purchased. Upon
confirmation by TARCANTA or TARCANTA LTD. to the bank and its escrow agent that
the goods listed on the purchase order conform to the definition of Barter
Goods, and upon further confirmation by the bank and its escrow agent that CIMAB
has declared on such purchase order that said Barter Goods are to be used for
public health purposes of the Cuban people, the bank and its escrow agent shall
pay the Third Party supplier in accordance with its invoice for the sale of the
items identified on the purchase order by transfer of funds, or honoring the
presentation of drafts, to or at the order of the Third Party supplier. Prior to
the initial payments into the Barter Account, TARCANTA or TARCANTA LTD. shall
determine that the bank at which the Barter Account is maintained has obligated
itself to act in accordance with the foregoing procedures concerning use of the
funds in the Barter Escrow Account, and shall be entitled to determine from time
to time that this obligation remains in effect. The Barter Escrow Account shall
be opened and maintained at Citibank International, plc, London, England, or
such other bank as may be mutually agreeable to the Parties, and TARCANTA and/or
TARCANTA LTD. will pay the fees required to establish and maintain the Barter
Escrow Account, including fees payable for the services of the escrow agent.
CIMAB will be entitled to all interest on the funds deposited into the Barter
Escrow Account, which interest shall also be payable in Barter Goods. CIMAB
shall be entitled to request that TARCANTA or TARCANTA LTD. transfer the Barter
Escrow Account to another first class bank that is not a Cuban national,
provided, however, that (a) such bank is a financial institution that is a U.S.
bank, a foreign subsidiary or branch of a U.S. bank, or a bank that is owned or
controlled by a U.S. bank, (b) TARCANTA or TARCANTA LTD. determines that the
successor bank has obligated itself to operate the account as set forth herein,
and (c) such transfer shall not cause TARCANTA or TARCANTA LTD. to pay
additional taxes in connection with the transfer of funds to, or the maintenance
of, such account. Use of the funds in the Barter Escrow Account for the purchase
of Barter Goods under this Section 5.10.3 shall include the purchase of Barter
Goods, as well as for shipping and insurance costs for delivery of said goods to
CIMAB in Cuba. The escrow agent of the bank shall be appointed by the bank with
the consent of CIMAB, TARCANTA and TARCANTA LTD., and shall be a national of any
country in the European Union.

5.10.4 Immediately upon U.S. law, and/or the U.S. Treasury
Department's Office of Foreign Assets Control, permitting payments required by
this Agreement to be made into the Barter Escrow Account to be made instead in
Cash to CIMAB, all payments required by this

Agreement to be made into the Barter Escrow Account shall instead be made in
Cash directly to CIMAB. Immediately upon U.S. law, or the U.S. Treasury
Department's Office of Foreign Assets Control, removing any restrictions on
Cuban nationals engaging in the transactions that, under the express terms of
this Agreement, Cuban nationals are disqualified from undertaking, such
disqualifications shall be deemed to have been eliminated from this Agreement.

5.10.5 In the event that U.S. law, or the decisions or orders of
U.S. government authorities, prevents CIMAB from actually receiving any of the
payments required to be paid to CIMAB under this Agreement, or prevents payment
into the Holding Account or the Barter Escrow Account, as required under this
Agreement, including without limitation payments required under this Article 5,
Article 6 and Article 7, or prevents the purchase of Bartered Goods by use of
funds in the Barter Escrow Account, or in the event of any change in United
States law or administrative practice that makes it impermissible for Cuban
nationals, or CIMAB, to purchase and import into Cuba Bartered Goods (which
circumstances hereafter in this Section 5.10.4 are described for convenience as
the "Event") CIMAB may, in its reasonable discretion, exercise the following
options:

(a) Upon occurrence of the Event, CIMAB may immediately suspend
fulfillment of any orders for the Licensed Products under this Agreement for the
Territory until such time as it is able to receive all payments required by this
Agreement. If CIMAB exercises this option, TARCANTA and TARCANTA LTD. will have
the right to manufacture additional quantities of Licensed Product to make up
for any shortfall.

(b) If, after six (6) months of its occurrence, the Event continues
in effect, CIMAB shall be entitled to Royalties on account of sales of the
Licensed Product in the Other Countries at the rate of [***] of Net Sales.

(c) In addition, between six (6) months and one (1) year following
the occurrence of the Event, TARCANTA or TARCANTA LTD. may transfer its rights
and obligations under this Agreement with respect to the Other Countries and
Mexico to a Third Party to be designated by TARCANTA or TARCANTA LTD. and
approved by CIMAB, such approval will be subject to the same provisions set
forth in Section 2.2.

(d) In addition, if, after one (1) year of the occurrence of the
Event, the Event prevents actual receipt outside the U.S. in the bank in a Third
Country designated pursuant to Section 5.10.1, or to the Barter Escrow Account,
as applicable, of the payments of Royalties for Licensed Product from the Other
Countries, or prevents the purchase of Bartered Goods by use of funds in the
Barter Escrow Account, or prevents Cuban nationals or CIMAB from purchasing and
importing into Cuba Bartered Goods, (i) TARCANTA and TARCANTA LTD. shall retain
all rights and obligations granted under this Agreement with respect to the U.S.
and Canada, and (ii) CIMAB may terminate all licenses to TARCANTA LTD. and
TARCANTA under the Licensed Patent Rights, the Licensed Know-How, and the
Improvements to make, have made, use, offer for sale, market, sell, and import
the Licensed Product in the Other Countries and Mexico, and all other rights
under this Agreement associated with the using, offering for sale, marketing,
selling and importing in the Other Countries and Mexico granted by, under or
pursuant to this Agreement. Upon such termination of rights with respect to the
Other Countries and Mexico, all Regulatory Approvals and Regulatory Applications
for the Other Countries and

Mexico shall be transferred, and shall be deemed transferred to, CIMAB, as well
as all data comprising preclinical and clinical studies performed by TARCANTA,
TARCANTA LTD. or their Affiliates in the Other Countries, to the extent that the
disclosure of any clinical study information is permitted under Applicable Laws
protecting the privacy of patients participating in such studies and to the
extent permitted under License number CU-73444 issued by the U.S. Department of
Treasury to CancerVax Corporation, or any subsequent modification thereof.
TARCANTA and TARCANTA LTD. shall provide all documents, and all cooperation, as
may be necessary to effectuate said transfers in a period of 3 months from the
date of receiving the Notice of Termination as prescribed below. A Notice of
Termination pursuant to this paragraph, issued by CIMAB, shall be deemed full
and sufficient proof of termination by all Third Parties, who shall be entitled
fully to rely upon same.

(e) CIMAB's termination of the license granted to TARCANTA LTD. and
TARCANTA with respect to the Other Countries and Mexico shall constitute
termination of any sublicense granted by TARCANTA LTD. or TARCANTA with respect
to the Other Countries and Mexico pursuant to the terminating license.

5.10.6 In the event that the Event abates, any modifications in the
Royalty rates pursuant to Section 5.10.5 and the options exercised by CIMAB in
accordance with Section 5.10.5, if any, shall remain in effect until the
following condition has been satisfied: that CIMAB has received an amount equal
to the amount it would have received had the Event not occurred, together with
(a) compound interest thereon at the rate of 1% per month, or such lesser amount
as required under Applicable Law, and upon satisfaction of the aforesaid
condition, at TARCANTA LTD. or TARCANTA's option, the status quo ante shall be
restored, and this Agreement shall continue in effect according to its terms
until expiration of its term as stated in Section 12.1.1 without any tolling of
the Term or its earlier termination with respect to the rights of TARCANTA LTD.
and TARCANTA in the Other Countries and Mexico pursuant to this Agreement.
TARCANTA LTD. and TARCANTA shall exercise their option to restore the status quo
ante within 90 days of the "condition" specified in the first sentence of this
Section 5.10.6 being satisfied. The Parties shall agree when the condition set
forth in the first sentence of this Section 5.10.6 shall have been satisfied;
pending the resolution of any dispute, pursuant to the Dispute Resolution
provisions or agreement, the condition set forth in the first sentence of this
paragraph shall be deemed not to have been satisfied.

5.10.7 In the event that any order of any U.S. court of competent
jurisdiction (including without limitation, its federal and state courts
asserting such jurisdiction) issued on account of claims, judgments or disputes
that do not arise out of CIMAB's own activities, prevents CIMAB from receiving
Payments in Cash, or prevents payments into the Holding Account or payments into
the Barter Escrow Account under this Agreement, or prevents the purchase of
Barter Goods by use of the funds in the Barter Escrow Account, or prevents CIMAB
from purchasing and importing into Cuba Barter Goods, which circumstances
hereafter in this Section 5.10.7 are described for convenience as the "Event",
then, CIMAB may, in its reasonable discretion, exercise the following options:

(a) Upon the occurrence of the Event, CIMAB may immediately suspend
fulfillment of any of its obligations under this Agreement to supply the
Licensed Products for the Other Countries with respect to any jurisdiction in
which the aforesaid Court order is enforceable

(hereafter, "affected jurisdiction"). If CIMAB exercises this option, TARCANTA
and TARCANTA LTD. will have the right to manufacture additional quantities of
Licensed Products to make up for any shortfalls.

(b) During the pendency of any litigation with respect to the
aforesaid court order, CIMAB shall be entitled to a royalty of [***] of Net
Sales from sales of the Licensed Products in the Other Countries except that
this subparagraph (b) shall be inapplicable to Royalties whose payment to CIMAB
is prevented by the aforesaid Court order. In the event that the litigation
results in the withdrawal or termination of any such Court order, and any funds
that had not been paid to CIMAB as a result of said Court order or decision are
paid to CIMAB, TARCANTA and/or TARCANTA LTD. shall be entitled to recover the
additional amount paid to CIMAB under this subparagraph, which recovery shall be
taken first from any past due payments released to CIMAB upon termination of the
Court order and, if not sufficient, by reduction of the Royalties payable to
CIMAB by twenty-five percent (25%), until the amount has been recovered.

(c) If litigation, if any, is unsuccessful in terminating the Court
order, then, upon the final decision in such litigation:

(i) CIMAB shall be entitled to a royalty of [***] of Net Sales
from sales of the Licensed Product in the Other Countries except that this
subparagraph (c)(i) shall be inapplicable to Royalties whose payment to CIMAB is
prevented by the aforesaid Court order;

(ii) TARCANTA or TARCANTA LTD. may transfer the rights and
obligations under this Agreement in the Other Countries in affected jurisdiction
to a Third Party to be designated by TARCANTA or TARCANTA LTD. and approved by
CIMAB, with such approval subject to the same provisions set forth in Section
2.2.

(iii) In addition, if, after 1 year of its occurrence, the
Event prevents actual receipt of Payments in Cash outside of the U.S. in the
bank in a Third Country designated pursuant to Section 5.10.1, or payment into
the Holding Account or payment into the Barter Escrow Account, of the payment of
Royalties with respect to the Other Countries due on account of sales of the
Licensed Products in any jurisdiction affected thereby, or prevents the purchase
of Barter Goods by use of the funds in the Barter Escrow Account, or prevents
CIMAB from purchasing and importing in to Cuba Bartered Goods, TARCANTA and
TARCANTA LTD. shall retain all rights and obligations granted under this
Agreement with respect to the U.S. and Canada, but CIMAB may terminate the
license under the Licensed Patent Rights, the Licensed Know-How, and the
Improvements to use, offer for sale, market, sell, and import the Licensed
Product in the Other Countries and Mexico in the affected jurisdiction, granted
by, under or pursuant to this Agreement. Upon such termination, all Regulatory
Approvals and Regulatory Applications in the Other Countries and Mexico in the
affected jurisdiction shall be transferred, and shall be deemed transferred to,
CIMAB. TARCANTA and TARCANTA LTD. shall provide all documents, and all
cooperation, as may be necessary to effectuate said transfers in a period of 3
months from the date of receiving the Notice of Termination as prescribed below.
A Notice of Termination pursuant to this paragraph, issued by CIMAB, shall be
deemed full and sufficient proof of termination by all Third Parties, who shall
be entitled fully to rely upon same.

***Certain information on this page has been omitted and filed separately with
the Commission. Confidential treatment has been requested with respect to the
omitted portions.

(iv) CIMAB's termination of the license granted to TARCANTA
LTD. and TARCANTA with respect to the Other Countries and Mexico shall
constitute termination of any sublicense granted by TARCANTA and TARCANTA LTD.
with respect to the Other Countries and Mexico pursuant to the terminating
license.

(d) In the event that, after the unsuccessful conclusion of the
aforesaid litigation, the Court order is vacated, extinguished, or expires, by
reason of satisfaction of the underlying judgment or claim or otherwise, any
modifications in Royalty rates pursuant to 5.10.6, and the options exercised by
CIMAB in accordance with 5.10.6, if any, shall remain in effect until CIMAB has
received an amount equal to the amount it would have received but for said Court
order (the "condition"). In the event the aforesaid condition is satisfied, at
TARCANTA LTD. or TARCANTA LTD.'s option, the status quo ante shall be restored,
and this Agreement shall continue in effect according to its terms until
expiration of its Term as stated in Section 12.1.1 without any tolling or its
earlier termination, pursuant to this Agreement. TARCANTA LTD. and TARCANTA
shall exercise their option to restore the status quo ante within 90 days of the
"condition" specified in the first sentence of this paragraph being satisfied.
The Parties shall agree when the condition set forth in the first sentence of
this paragraph shall have been satisfied; pending the resolution of any dispute,
pursuant to the Dispute Resolution procedures, or otherwise the condition shall
be deemed not to have been satisfied.

5.10.8 Notwithstanding the provisions of Section 5.10.7, in the
event that any Party, in good faith, believes that the Court order referenced in
Section 5.10.7 was issued by a Court lacking competent jurisdiction, both
parties will commit to join in litigation to overturn the court order as quickly
as possible and, CIMAB shall not be entitled to implement any of its' remedies
under Section 5.10.7 (b) and 5.10.7(c) for a period of six (6) months from the
date on which the Court order was issued, and all Parties agree to join in
litigation and use their best efforts to seek a withdrawal of the Court order.

5.10.9 In the event that any order of any court of the U.S. that
lacks competent jurisdiction, including without limitation, any U.S. federal and
state courts, issued on account of claims, judgments or disputes that do not
arise out of CIMAB's own activities, prevents actual receipt of Payments in Cash
outside of the U.S. in a bank in a Third Country designated pursuant to Section
5.10.1, or prevents payment into the Holding Account or the Barter Escrow
Account, required under this Agreement, or prevents the purchase of Barter Goods
by use of the funds in the Barter Escrow Account, or prevents CIMAB from
purchasing and importing into Cuba Barter Goods, then the Parties agree to use
Reasonable Commercial Efforts to secure the elimination of any such order as
quickly as possible.

5.11 Books of Account. TARCANTA and TARCANTA LTD. shall keep and maintain
accurate and complete records and books of account in sufficient detail and form
so as to enable verification of the payments due to CIMAB under this Agreement.

5.12 Audit Rights. TARCANTA and TARCANTA LTD. shall maintain records and
books of account relating to the Licensed Product for a period of not less than
seven (7) years following the year to which the records pertain. TARCANTA and

by independent certified public accountants selected by CIMAB who are qualified
in the application of U.S. generally accepted

accounting principles ("GAAP"), including without limitation independent
certified public accountants who are Cuban nationals. No more than one (1) such
audit may be conducted by or on behalf of CIMAB in any calendar year. All audits
shall be conducted during TARCANTA and TARCANTA LTD.'s normal business hours and
only after reasonable written prior notice. Without limitation, thirty (30) days
prior written notice shall be deemed reasonable notice. If the audit shows that
TARCANTA or TARCANTA LTD. owes a payment (including reimbursement of any
previously overpaid amount) to CIMAB under this Agreement, TARCANTA or TARCANTA
LTD., as applicable, shall promptly make such payment. The cost of such
examination shall be borne by CIMAB, unless such audit reveals that TARCANTA or
TARCANTA LTD. underpaid CIMAB by more than ten percent (10%), then TARCANTA or
TARCANTA LTD. shall bear the cost of such audit.

5.13 Reports. Beginning after TARCANTA or TARCANTA LTD. has received a
Regulatory Approval to market the Licensed Products in the Territory, TARCANTA
and TARCANTA LTD. shall provide CIMAB with a report detailing all sales
activities for the Licensed Products in the Territory during the preceding
calendar quarter. Such reports shall be provided to CIMAB within forty-five (45)
days following the end of each calendar quarter.

Once CIMAB demonstrates to TARCANTA and TARCANTA LTD.'s reasonable satisfaction
that it is able to fully support the quantity requirements and to fully comply
with the Applicable Laws, TARCANTA LTD. and TARCANTA shall increase their
purchases of the Licensed Products for the Other Countries to the extent of
CIMAB's ability to supply the Licensed Products. To the extent that TARCANTA or
TARCANTA LTD. supplies the Licensed Products for sale in the Other Countries

such Licensed Products shall be increased from [***] to [***] of Net Sales from
the sale of such Licensed Products in the Other Countries.

6.1.4 Failure to Supply by TARCANTA or TARCANTA LTD. In the event
that TARCANTA or TARCANTA LTD. is unable to support quantity requirements for
the Licensed Product for the U.S., Canada and Mexico, or in the event that
TARCANTA or TARCANTA LTD. fails to manufacture the Licensed Product in
compliance with the Applicable Laws, and provided that CIMAB and its Contract

Manufacturer shall have the right to manufacture and TARCANTA and TARCANTA LTD.
shall have the obligation to purchase from CIMAB or its Contract Manufacturer,
the Licensed Products to meet quantity requirements or Applicable Law
requirements, but only to the extent that TARCANTA or TARCANTA LTD. is unable to
satisfy quantity requirements or Applicable Law requirements. Notwithstanding
the foregoing, neither TARCANTA nor TARCANTA LTD. shall be under any obligation
to bear any costs whatsoever associated with CIMAB or its Contract Manufacturer
becoming an approved supplier under any BLA or other Regulatory Approval
relevant to the U.S., Canada or Mexico. Once TARCANTA OR TARCANTA LTD.
demonstrates that it is able to fully support the quantity requirements and to
fully comply with the Applicable Laws, TARCANTA or TARCANTA LTD. shall resume
supplying the Licensed Products to U.S., Canada and Mexico.

6.2 Transfer of Transferred Assets and Licensed Know-How. CIMAB shall

TARCANTA, TARCANTA LTD. and their Affiliates in a timely manner.

contract with one or more Contract Manufacturers to Finish, manufacture and
supply Licensed Products to TARCANTA and TARCANTA LTD. and their Sublicensees,
if any, in accordance with the terms of this Agreement, provided, however, that
no assignment of rights to a Contract Manufacturer hereunder shall relieve
CIMAB, TARCANTA or TARCANTA LTD. of complying fully with their obligations under
this Agreement. TARCANTA, TARCANTA LTD. and CIMAB agree that all agreements
engaging a Contract Manufacturer shall provide that the Contract Manufacturer
will comply with (i) all Applicable Laws and all specifications and
manufacturing and quality control procedures for the manufacture and quality
assurance of the Licensed Products reasonably established by TARCANTA and
TARCANTA LTD., and (ii) the Confidentiality provisions of this Agreement.

own all Improvements. For the purpose of clarification, except as expressly set
forth in this Agreement, no right, license or interest is granted by either

respective intellectual property. CIMAB, TARCANTA and TARCANTA LTD., and their
Affiliates and Sublicensees, may use any of the Improvements, during and after
the Term of this Agreement, without payment of any royalty, fee or consideration
to the other Parties.

10.2 Ownership of Regulatory Applications and Regulatory Approvals:

10.2.1 In the Territory, TARCANTA and TARCANTA LTD. shall own all
right, title and interest in all Regulatory Applications necessary to obtain
Regulatory Approvals required to conduct clinical trials for Licensed Products

Approval obtained in connection therewith. All Regulatory Applications in the
Territory, together with any Regulatory Approvals obtained in connection
therewith, shall be filed in the name of TARCANTA or TARCANTA LTD.

10.2.2 Each Party shall retain ownership and control of any of its
Confidential Information included in any Regulatory Application. Notwithstanding
the previous sentence, each Party agrees that, except as restricted under
License number CU-73444 issued by the U.S. Department of Treasury to CancerVax

the other Party any Confidential Information necessary for the filing,
maintenance, modification or protection of any Regulatory Application by such
other Party, or as required under any reporting obligation under the Applicable
Laws.

10.3 Prosecution and Maintenance of Licensed Patent Rights. Except as
otherwise agreed by the Parties, beginning on the Effective Date, TARCANTA and
TARCANTA LTD. shall be responsible for the preparation, filing, prosecution and
maintenance of any and all patent applications and patents in the Territory that
are included in the Licensed Patent Rights, including all payment obligations,
with the exception of (a) those patents and patent applications designated in
Exhibit A as related to the "Neisseria P64K Protein" technology, which shall be
prepared, filed, prosecuted and maintained by HEBER or its Licensor, consistent
with its obligations to CIMAB, and (b) the patents and patent applications
designated in Exhibit A as "HER-1" technology, which shall be prepared, filed,
prosecuted and maintained by CIM, in consultation with TARCANTA and TARCANTA
LTD., consistent with its obligations to CIMAB and CIMAB's obligations to
TARCANTA and TARCANTA LTD.; provided, however, that if the Parties agree in the
future to separate the claims thereof into applications which solely cover the
HER-1 technology, then TARCANTA and TARCANTA LTD. shall from such point forward,
bear the responsibility for the preparation, filing, prosecution and maintenance
of patents and patent applications which relate solely to the HER-1 technology.

10.3.1 CIMAB shall execute all necessary documents and otherwise
provide reasonable assistance, free of charge to TARCANTA and TARCANTA LTD., for
all actions TARCANTA and TARCANTA LTD. reasonably deem necessary to undertake
relating to the preparation, filing, prosecution, and maintenance of any and all
patent applications and patents in the Territory that are included in the

effective date of such written notice. CIMAB shall thereafter have a right, but
not an obligation, to assume the responsibility for the preparation, filing,
presentation and maintenance of any and all patent applications and patents that
are included in the Licensed Patent Rights in such country(ies) in the Territory
where TARCANTA or TARCANTA LTD. has elected to abandon its rights. In the event
that CIMAB has assumed the responsibility for the preparation, filing,
presentation and maintenance of any and all patent applications and patents that
are included in the Licensed Patent Rights in such country(ies) in the Territory
where TARCANTA and/or TARCANTA LTD. have elected to abandon such rights,
TARCANTA and TARCANTA LTD.'s rights, as the case may be, with respect to the
Licensed Product in such country(ies) under this Agreement shall no longer be of
any effect.

10.4 Enforcement of Licensed Patent Rights

10.4.1 If any patent within the Licensed Patent Rights is or might
reasonably be infringed by a Third Party in the Territory (an "Infringement"),
the Party first having knowledge

of such Infringement shall promptly notify the other Parties in writing. Such
notice shall set forth the facts of such Infringement in reasonable detail.

10.4.2 TARCANTA and TARCANTA LTD. shall have the right, but not the
obligation, to take action in their own names and at their sole expense to
secure the cessation of any Infringement or to institute, prosecute and control
legal proceedings to prevent or restrain such Infringement. CIMAB agrees to
timely assist TARCANTA and TARCANTA LTD. in the prosecution of any action or
legal proceedings related to such Infringement, and agrees to be joined, and to
cause its Licensors to be joined, as party plaintiffs and to give the TARCANTA
and TARCANTA LTD. reasonable assistance and authority to control, file,
prosecute and settle the suit. Subject to the foregoing, CIMAB shall have the
right, but not the obligation, to participate at its own cost and expense in any
suit or other proceeding wherein the validity or enforceability of any Licensed
Patent Right is at issue in the context of a claim or defense. All of TARCANTA
and TARCANTA LTD.'s costs and expenses in bringing such suits (including
TARCANTA and TARCANTA LTD.'s internal costs and expenses that are specifically
attributable thereto) shall be reimbursed first out of any damages or other
monetary awards recovered in favor of the Parties. Any remaining damages or
other monetary awards shall be allocated [***] to CIMAB and [***] to TARCANTA
and TARCANTA LTD.

10.4.3 If TARCANTA and TARCANTA LTD. elect not to exercise their
right to prosecute or take other appropriate action in connection with an
Infringement or fail to take any such action within ninety (90) days of first
receiving notice of such Infringement, CIMAB may do so at its own expense. If
such case, TARCANTA and TARCANTA LTD. agree to assist CIMAB in the prosecution
of any action or legal proceedings related to such Infringement. Notwithstanding
anything in this Agreement to the contrary, TARCANTA and TARCANTA LTD. shall
have the right, but not an obligation, to participate at their own cost and
expense in any suit or other proceeding wherein the validly or enforceability of
any Licensed Patent Right is being invoked in the context of a claim or defense.
All of CIMAB's costs and expenses in bringing such suits (including CIMAB's
internal costs and expenses that are specifically attributable thereto) shall be
reimbursed first out of any damages or other monetary awards recovered in favor
of the Parties. Any remaining damages or other monetary awards shall be
allocated [***] to TARCANTA and TARCANTA LTD. and [***] to CIMAB.

10.4.4 The Party that takes action or prosecutes legal proceedings
relating to the Infringement in accordance with this Agreement shall be
responsible for the selection of counsel to prosecute legal proceedings.

10.4.5 In no event shall either Party settle an action or proceeding
against an infringer with respect to an Infringement in the Territory without
the prior written consent of the other Parties. Such consent shall not be
unreasonably withheld or delayed, and may be withheld only if such settlement
would materially and adversely affect the interest of such other Parties.

10.4.6 Infringement of Third Party(ies) Rights. If any activities by
TARCANTA or TARCANTA LTD. under this Agreement, including the practice of the
Licensed Patent Rights, the Licensed Know-How, or the manufacture, use or sale
of the Licensed Products by TARCANTA or TARCANTA LTD., their Affiliates or
Sublicensees consistent with the rights granted under this Agreement within the
Territory results in a claim of infringement of the

the Commission. Confidential treatment has been requested with respect to the
omitted portions.

intellectual property rights of a Third Party against TARCANTA or TARCANTA LTD.,
their Affiliates or Sublicensees, TARCANTA and TARCANTA LTD. shall have the
right, using counsel of their own choice, to defend such claim. CIMAB agrees to
cooperate fully with TARCANTA and TARCANTA LTD. in their defense of the claim.
Notwithstanding anything in this Agreement to the contrary, CIMAB shall have the
right, but not the obligation, to participate at its own cost in the defense of
such claim. All of TARCANTA and TARCANTA LTD.'s costs and expenses in defending
such claims (including TARCANTA and TARCANTA LTD.'s internal costs and expenses
which are specifically attributable thereto) shall be offset by TARCANTA and
TARCANTA LTD. exclusively against [***] of any Royalties and any other amounts
due to CIMAB under this Agreement. Such offset rights shall be made only where
the claim of infringement arises from the sale, use, manufacture or importation
of the Licensed Products, provided that such claim of infringement does not
arise due to any invention or improvement incorporated into the Licensed
Products by TARCANTA or TARCANTA LTD. without the knowledge of CIMAB.

10.5 Trademarks and Identification.

10.5.1 TARCANTA and TARCANTA LTD. shall, at their own expense,
select, register and maintain the trademarks used by each such entity with
respect to the Licensed Products. Neither CIMAB nor any of its Affiliates,
Licensors or sublicensees, other than TARCANTA and TARCANTA LTD., shall have any
rights in respect of such trademarks, and CIMAB agrees to use its best efforts
to prevent any of its Affiliates, Licensors and sublicensees other than TARCANTA
and TARCANTA LTD., from using such trademarks in any way.

10.5.2 CIMAB agrees to give TARCANTA and TARCANTA LTD. prompt
written notice of any unlicensed use by Third Parties of any trademark used by
TARCANTA or TARCANTA LTD. with respect to the Licensed Products of which CIMAB
has knowledge.

10.5.3 TARCANTA and TARCANTA LTD. shall have the exclusive right,
but not the obligation, to take action in their own names and at their sole
expense to secure the cessation of any infringement or misappropriation of its
trademarks or to institute, prosecute and control legal proceedings to prevent
or restrain such infringement or misappropriation of its trademarks. CIMAB
agrees to use its best efforts to assist TARCANTA and TARCANTA LTD., at TARCANTA
or TARCANTA LTD.'s expense, in the prosecution of any action or legal
proceedings related to the infringement or misappropriation of such trademarks.

10.5.4 If permitted by Applicable Laws, all Licensed Products shall
bear labeling that states that such products are either manufactured under
license from CIMAB, in the case of Licensed Products manufactured by TARCANTA or
TARCANTA LTD., their Sublicensees and Contract Manufacturers, or, in the case of
Licensed Products purchased from CIMAB, that identifies CIMAB, with its address,
as the manufacturer of the Licensed Products. TARCANTA and TARCANTA LTD. shall
xxxx all Licensed Products that they manufacture for commercial sale with a
legend identifying the issued patents that pertain thereto.

ARTICLE 11

CONFIDENTIALITY

11.1 Confidentiality; Exceptions. Except as otherwise provided in this
Agreement, the Parties agree that, during the term of this Agreement and for
five (5) years thereafter, all non-public, proprietary or "confidential" marked
invention disclosures, know-how, data, and technical, financial and other
information of any nature whatsoever (collectively, "Confidential Information"),
disclosed or submitted, either orally or in writing (including, without
limitation by electronic means) or through observation, by one Party (the
"Disclosing Party") to the other Party (the "Receiving Party") hereunder shall
be received and maintained by the Receiving Party in strict confidence, shall
not be used for any purpose other than the purposes expressly permitted by this
Agreement, and shall not be disclosed to any Third Party (including, without
limitation in connection with any publications, presentations or other
disclosures). Notwithstanding the foregoing, the Receiving Party may, subject to
the provisions of this Agreement, disclose the Disclosing Party's Confidential
Information to those of its and its Affiliates' and its Sublicensees' directors,
officers, employees, agents, consultants, clinical investigators and Contract
Manufacturers that have a need to know such Confidential Information to achieve
the purposes of this Agreement; provided, however, that such Party shall ensure
that it and its Affiliates' and Sublicensees' directors, officers, employees,
agents, consultants, clinical investigators or Contract Manufacturers to whom
disclosure is to be made are bound by, and take reasonable efforts to ensure
compliance with, the confidentiality terms hereof. Each Party will promptly
notify the other upon discovery of any unauthorized use or disclosure of the
Confidential Information. Confidential Information belongs to and shall remain
the property of the Disclosing Party. The provisions of this Article 11 shall
not apply to any information that can be shown by the Receiving Party:

(a) To have been known to or in the possession of the Receiving Party
prior to the date of its actual receipt from the Disclosing Party;

(b) To be or to have become readily available to the public other than
through any act or omission of the Receiving Party in breach of this Agreement
or any other agreement between the Parties;

(c) To have been disclosed to the Receiving Party, other than under an
obligation of confidentiality, by a Third Party which had no obligation to the
Disclosing Party not to disclose such information to others; or

(d) To have been subsequently independently developed by the Receiving
Party without use of the Confidential Information as demonstrated by competent
written records.

11.2 Authorized Disclosures. Notwithstanding anything in Section 11.1 to
the contrary, each Party may disclose Confidential Information hereunder solely
to the extent such disclosure is reasonably necessary in connection with
submissions to any Government Authority or in filing or prosecuting patent
applications contemplated or prosecuting or defending litigation or complying
with Applicable Laws or conducting Development Work for the purposes expressly
permitted by this Agreement; provided that in the event of any such disclosure
of the

Disclosing Party's Confidential Information by the Receiving Party, the
Receiving Party will, except where impracticable, give reasonable advance notice
to the Disclosing Party of such disclosure requirement (so that the Disclosing
Party may seek a protective order and or other appropriate remedy or waive
compliance with the confidentiality provisions of this Article 11) and will use
its reasonable efforts to secure confidential treatment of such Confidential
Information required to be disclosed. Notwithstanding the above, each Party may
disclose pre-clinical and clinical data and results relating to Licensed Product
to qualified medical professionals for the limited purposes of marketing
Licensed Product and conducting medical education initiatives reasonably
designed to increase sales of Licensed Product.

11.3 Return of Confidential Information. The Receiving Party shall keep
Confidential Information belonging to the Disclosing Party in appropriately
secure locations. Upon the expiration or termination of this Agreement, any and
all Confidential Information possessed in tangible form by a Receiving Party,
its Affiliates or Sublicensees, or its or any of their officers, directors,
employees, agents, consultants or clinical investigators and belonging to the
Disclosing Party, shall, upon written request, be immediately returned to the
Disclosing Party (or destroyed if so requested) and not retained by the
Receiving Party, its Affiliates or Sublicensees, or any of their officers,
directors, employees, agents, consultants or clinical investigators; provided
however that a Party may retain one (1) copy of any Confidential Information in
an appropriately secure location, which by Applicable Laws it must retain, for
so long as such Applicable Laws require such retention but thereafter shall
dispose of such retained Confidential Information in accordance with Applicable
Laws or this Section 11.3.

11.4 Publications and Announcements. Except as otherwise permitted under
this Agreement or as required by law, regulation, or court order, each Party
agrees not to publish any Confidential Information received from the other
Party. Except as required by law, regulation or court order, each Party agrees
that, without obtaining the other Party's prior written approval for any
publication or any presentation, which shall not be unreasonably withheld, such
Party shall not publish or present (i) any Confidential Information generated by
either Party related to the development or commercialization of Licensed
Product, or (ii) the results of any clinical trial studies or non-clinical
studies or investigations carried out by either Party related to the development
of Licensed Product. At least sixty (60) days prior to any such publication or
presentation, the Party seeking to publish such information (the "Publishing
Party") shall provide the other Party with a copy of the proposed abstract,
manuscript or presentation (including, without limitation information to be
presented verbally) for review. The other Party shall respond in writing to the
Publishing Party within such time period with either approval of the proposed
material or a specific statement of (a) concern based upon the need to seek
patent protection, (b) concern regarding competitive disadvantage arising from
the proposal, or (c) concern regarding the timing and circumstances of such
disclosure in light of the other Party's business. In the event that the other
Party has concerns about disclosure of Confidential Information, the Publishing
Party agrees to provide the other Party with any additional information relating
to the proposed disclosure, as reasonably requested. In the event of concern
relating to patent protection, the Publishing Party agrees not to submit such
abstract or manuscript for publication or to make such presentation until the
other Party has had a reasonable period of time to seek patent protection for
any material in such publication or presentation which it believes is patentable
or to resolve any other issues, such period not to exceed sixty (60) additional
days. In the event of concern regarding competitive disadvantage or

the timing and other circumstances relevant to the disclosure, the Parties will
negotiate in good faith to attempt to arrive at a compromise to permit the
Publishing Party an opportunity to publish or present the disclosure within a
reasonable period of time. The Publishing Party also agrees to delete from any
such abstract or manuscript or presentation any Confidential Information that
the other Party reasonably believes has commercial value based upon the secrecy
of such information. Once approval for a publication or presentation has been
granted, the Publishing Party shall be entitled to use information contained in
such publication or presentation after the date of its publication or
presentation without seeking further approval. It is understood that general
comments made by either Party relating to the relationship between the Parties
established by this Agreement, including, for example, general comments made in
response to inquiries at professional meetings and other similar circumstances,
are not intended to be restricted by the provisions of this Article 11 provided
that such information has been disclosed to the public previously or cleared for
such disclosure by the non-disclosing Party. It is understood further that
Confidential Information may be disclosed by either Party to Third Parties bound
by non-disclosure agreements to the extent such Confidential Information (1) is
not specific to the Licensed Product and (2) is disclosed in relation to matters
outside the Parties' collaboration efforts with respect to Licensed Product.
Prior to any such disclosure, the disclosing Party will provide such disclosures
to the other Party for such Party's approval, which shall not be unreasonably
withheld.

cause if any other Party commits a material breach of a material term of this
Agreement, which material breach is not materially cured within sixty (60) days
after written notice from a non-breaching Party specifying the material breach,

cure within such period, the breaching Party is not making diligent, good faith,
best efforts to materially cure such material breach. The Parties acknowledge
and agree that failure to exercise any right or option, or to take any action
expressly within the discretion of a Party shall not be deemed to be a material
breach hereunder.

and may fully exercise all of their rights and elections under such Bankruptcy

of or in connection with or related to this Agreement (a "Dispute"), the Parties
shall first seek to settle the Dispute in good faith by negotiation and
consultation between themselves, including referral of the Dispute to the chief
executive officers of each Party. When a Party believes that a Dispute has
arisen, that Party will give the other Parties prompt written notice of the
Dispute (a "Dispute Notice"). All negotiations pursuant to this Section 14.2,1
shall be on a without prejudice basis, and nothing said or disclosed, nor any
document produced, in the course of such negotiations which is not otherwise

resolve the Dispute (or agree upon a mechanism to resolve the Dispute) within
thirty (30) days of the date of the Dispute Notice, such Dispute shall be
referred by any Party to arbitration proceedings pursuant to Section 14.2.2.

14.2.2 Subject to Section 14.2.1, the Parties agree that any Dispute shall
be finally settled under the Rules of Arbitration of the International Chamber

terms of this Section 14.2.2. The seat of the arbitration shall be London,
England, unless another location is mutually agreed by the Parties, provided
always that the seat of the arbitration is in a state which has ratified the New
York Convention on the Recognition and Enforcement of Foreign Arbitral Awards
(the "New York Convention"). The arbitral tribunal shall be composed of three
(3) independent arbitrators, two (2) of whom shall be nominated by the Parties
to the Dispute and the third, who shall act as Chairman, who shall be jointly
nominated by the party-nominated arbitrators. In the event that there are three
Parties to the Dispute, the Claimant party(ies) shall (together) nominate one
arbitrator and the Respondent Party(ies) shall (together) nominate one
arbitrator. None of the arbitrators shall be nationals of the U.S. or Cuba. The
joint languages of the arbitration shall be Spanish and English, unless the
Parties agree otherwise. The arbitral tribunal may award interim or ancillary
relief. Judgment on the award, and on any interim or ancillary relief, may be
entered in any court having jurisdiction thereof or having jurisdiction over the
Parties or their assets, or over the subject matter at issue. The arbitral
tribunal shall have the power to rule on its own jurisdiction, including any
objections with respect to the existence or validity of this arbitration
agreement. The arbitral award shall be final and binding on the Parties, who
hereby waive any right of appeal. Such award shall be enforceable pursuant to
the New York Convention. The Parties agree that this Agreement and any Dispute
are commercial in nature under the laws of the Republic of Cuba, the U.S. and
England and Wales, including the laws relating to arbitration. This paragraph
shall be treated as an agreement independent of the other terms of this
Agreement. A decision by the arbitral tribunal that this Agreement is null and
void shall not entail ipso jure the invalidity of this arbitration clause.

in this agreement to the contrary, the Parties understand and agree that any and
all actions that can or must be taken by TARCANTA, TARCANTA LTD., and/or their

and shall continue to be limited to the extent that the performance or

applicable Court order, but that non-performance or other failure to fully
perform by TARCANTA, TARCANTA LTD. and/or their Affiliates and Sublicensees on
account of U.S. law and/or any applicable Court order in no way limits CIMAB'S
rights and remedies as delineated in Sections 5.10, 12.6.2 and 15.1.1.
