by Valera but not incorporated. In the event that Valera does not respond to
BioPro within thirty (30) Business Days of the receipt of a Marketing Plan, such
Marketing Plan will be deemed to be acceptable to Valera. Notwithstanding
anything else contained herein to the contrary, at the request of either Party,
the Parties shall meet semi-annually to review proposed marketing plans for the
Product.

pursuant to Section 3.1 on the express conditions that: (a) BioPro enters into a
written agreement with the sublicensee that binds the sublicensee to compliance
with all the terms and conditions of this Agreement applicable to BioPro; and
(b) no later than ten (10) days after sublicensing, BioPro also provides Valera
with a full copy of the agreement referred to in clause (a). Sublicensing shall
not relieve BioPro of any of its obligations under this Agreement. BioPro shall
be liable for any sublicensee's failure to perform any term or condition of this
Agreement as if BioPro itself breached the applicable term or condition of this
Agreement.

     3.11 OTHER COUNTRIES.  Valera acknowledges that BioPro requested that the
Other Countries be part of the Territory. However, because of licensing
arrangements with third persons, Valera is unable to include any of the Other
Countries as part of the Territory under the terms and. conditions of this
Agreement as of the Effective Date, Valera will use commercially reasonable
efforts to amend its licensing arrangements such that it can include one or more
of the Other Countries within the Territory under the same terms and conditions
of this Agreement and, to the extent Valera is successful in so doing, Valera
will notify BioPro of the same and the Territory will be deemed to include the
Other Countries with respect to which Valera was successful. If Valera is not
able to amend its licensing arrangements so as to include one or more of the
Other Countries within the Territory under the same terms and conditions of this
Agreement, Valera will notify BioPro, and Valera and BioPro will promptly meet
to discuss potential changes to this Agreement (particularly the arrangements
set forth in Article 7) with respect to such Other Countries.

possible, be the same as the product name used in the United States (but may
vary by Indication), as well as certain other trademarks of Valera and
trademarks of BioPro (other than a product name of BioPro) and use the trade

line that indicates the ownership of each Party's trademarks.

     4.2 OBLIGATIONS AND CONDITIONS.  No Promotional Materials bearing the
Trademarks may be used without Valera's prior written approval, which consent
shall not be unreasonably withheld or delayed but shall be conditioned upon
maintaining the distinctiveness of the trademarks of each Party and including a
tag line that indicates Valera's ownership of the Trademarks. It is agreed by
the Parties that in the event that Valera does not respond to BioPro's
submission of the new Promotional Materials or labeling within ten (10) Business
Days, consent shall be deemed to be granted. Notwithstanding anything to the
contrary, BioPro's use of the Trademarks shall be conditioned upon BioPro's
compliance with Valera's then-current quality standards, which standards Valera
may update from time to time by written notice to BioPro, it being understood
that BioPro may use up any packaging, labeling or Promotional Materials that it
has at the time of the update, either in stock or in process.

used in connection with the labeling and marketing of the Product in each
country of the Territory for use in the Primary Indication; provided that: (a)

owned by BioPro or licensed by BioPro from a Third Party on the Product; and (b)
each Party may use up any packaging, labeling or Promotional Materials that it
has at the time of the discontinuance, alteration or addition, either in stock
or in process.

     4.5 NO OTHER RIGHTS; ALLOCATION OF GOODWILL.  Except for the licenses
granted by each of Valera and BioPro to the other under this Agreement, neither
Party shall acquire any right, title, or interest in any trademark, trade name,
logo or trade dress of the other Party by reason of this Agreement. Each of
BioPro and Valera shall be responsible for registering, as necessary, its own
trademarks, trade names, logos and trade dress. BioPro acknowledges that all use
of any of Valera's trade names, trademarks, trade dress and logos and all of the
goodwill associated therewith shall inure solely to Valera's benefit. Likewise,
Valera acknowledges that all use of any of BioPro's trademarks, trade dress,
trade names, and logos, and all of the goodwill associated therewith shall inure
solely to BioPro's benefit.

     4.6 CONFUSINGLY SIMILAR MARKS.  BioPro shall not authorize or undertake any

in such quantities as, in Valera's opinion, are required to fill all orders and
for maintaining such inventory levels of raw materials and packaging components
as are required to meet BioPro's then-current forecast for the Product (as
delivered pursuant to Section 6.3). BioPro shall be responsible for supplying
camera-ready proofs of all Labels and other artwork to be included with the
Product.

     5.2 LABELING.  The Product supplied under this Agreement will be the
Product packaged for use in the United States including all Labels for use in
the United States. BioPro shall be responsible for making changes to the
labeling and packaging necessary to comply with all Regulatory Approvals
(including, without limitation, oversticking labels on the Labels or repackaging
the Product using labels, package inserts and documentation other than or in
addition to the Labels) and bear all costs related to the same. From time to
time, and in any event promptly following Valera's request, BioPro shall notify
Valera of all labeling and repackaging activities undertaken by or on behalf of
BioPro to comply with all Regulatory Approvals in the Territory.

     5.3 FAILURE TO SUPPLY.  In the event that Valera or its Affiliates are
unable to supply the Product in specified quality or in quantities sufficient to
meet forecast demand for a successive period of ninety (90) Business Days, then
BioPro may elect to have the Product made by a Third Party manufacturer
designated by Valera and approved by BioPro, which approval shall not be
unreasonably withheld, conditioned, denied or delayed. If BioPro makes such an
election, Valera shall grant the Third Party manufacturer a non-exclusive,
royalty-free license under the Intellectual Property for the sole purpose of
manufacturing and selling to BioPro the quantity of the Product that Valera is
unable to supply.

     5.4 SUPPLY RESUMPTION.  If BioPro exercises its rights to have a Third
Party manufacturer manufacture the Product pursuant to Section 5.3 and
thereafter during the Term Valera desires to resume supplying BioPro with the
Product (whether by Valera or otherwise), then Valera shall notify BioPro of
such desire. BioPro shall then resume purchasing Product exclusively from Valera
for the remainder of the Term as soon as Valera demonstrates to BioPro's
reasonable satisfaction that Valera (whether by Valera or otherwise) is capable
of reestablishing a satisfactory supply of the Product; provided that BioPro
shall not be required to cancel any purchase orders for the Product issued to
the Third Party manufacturer that were issued in accordance with the Forecasts
provided to Valera pursuant to Section 6.3 prior to the date that Valera gave
BioPro notice of its desire to resume supply and cover periods no more than six
(6) months after the date that Valera gave BioPro notice of its desire to resume
supply. If and when Valera resumes supplying the Product pursuant to this
Section 5.4, the Third Party manufacturer shall be required to return to Valera
all information provided to the Third Party manufacturer pursuant to Section 5.3
and any license granted to the Third Party manufacturer shall terminate.
Notwithstanding anything in this Agreement to the contrary, upon the termination
of this Agreement for any reason, the Third Party manufacturer shall be required
to return to Valera all information provided to Third Party manufacturer
pursuant to Section 5.3 and any license granted to the Third Party manufacturer
shall terminate.

information pertinent to the marketing, sale and promotion of the Product
relating to any Improvements, which Valera may make from time to time to the
Product, or to any new formulation of the Product. To the extent reasonably
possible, Valera shall provide BioPro with six (6) months prior written notice
of any anticipated Improvements or new formulations.

     5.7 SHELF LIFE.  Each unit of the Product will have a remaining shelf life
of at least eighteen (18) months at the time of shipment to BioPro; provided
that it is understood that the Implant is intended to be inserted into a human
body for twelve (12) of such eighteen (18) months.

     5.8 COMPLIANCE WITH LAWS.  BioPro shall comply with all applicable Laws in
relation to the handling, storage, distribution and sale of the Product in each
country of the Territory and Valera's then-current instructions relating to
handling, storage and shipment of the Products in each country of the Territory.

              ARTICLE 6 - FORECASTS/ORDERING/TITLE AND RISK/RETURNS

     6.1 ORDERING.  BioPro may order units of the Product by issuing binding
purchase orders (each, a "PURCHASE ORDER") to Valera pursuant to the terms of
this Agreement. Each Purchase Order shall state the quantity of the Product to
be purchased, delivery date(s) and routing instructions, destination or
destinations. No different or additional terms or conditions on any purchase
order, acknowledgment or other transmittal, whether a standard business form or
otherwise, utilized by BioPro or Valera in connection with the sale of the
Product shall be construed or deemed to be an amendment of or supplement to this
Agreement or otherwise binding on either BioPro or Valera.

     6.2 ACCEPTANCE OR REJECTION OF PURCHASE ORDERS.  Valera shall indicate its
acceptance or rejection of each Purchase Order within ten (10) Business Days
after receipt; provided that Valera may reject a Purchase Order, in whole or in
part, only if: (a) the Purchase Order fails to comply with the terms and
conditions of this Agreement; (b) the delivery date is less than one hundred
fifty (150) days from the date of Valera's receipt of such Purchase Order; or
(c) if the volume under the Purchase Order and all other accepted Purchase
Orders covering the applicable monthly period exceeds the volume set forth in
BioPro's then-current forecast (delivered pursuant to Section 6.3) by more than
ten percent (10%). If requested by BioPro following BioPro's receipt of Valera's
rejection notice under clause (c) above, Valera will use commercially reasonable
efforts to deliver the excess volume of the Product specified in the rejected
Purchase Order, but Valera's failure to so deliver the excess volume shall not
be a breach of this Agreement. Valera's sole obligation in filling accepted
Purchase Orders shall be to use commercially reasonable efforts to fill BioPro's
orders for the Product. In no event shall Valera be liable to any third party
for Valera's failure to deliver the Product to BioPro by any delivery due date
set forth in any Purchase Order.

rolling forecast (the "FORECAST") of BioPro's estimated requirements of the

such Forecast shall reflect a good faith attempt by BioPro to estimate quantity
requirements of the Product, based on anticipated demand therefor.

     6.4 SHIPMENT.  Valera will use diligent efforts to ship the Product ordered
by BioPro within one hundred and fifty (150) days after its acceptance of
BioPro's purchase order. The Products will be shipped EXW (Incoterms 2000)

Product is suitably packed for shipment in standard containers.

     6.5  DELIVERY AND ACCEPTANCE.

          6.5.1. ACCEPTANCE.  BioPro shall not be obliged to accept delivery of
any lot or batch of the Product unless the lot or batch complies with the

considered accepted by BioPro unless BioPro has rejected the same by delivering
written notice thereof to Valera as soon as is reasonably possible but in any
event no later than thirty (30) days after delivery of such lot or batch of the
Product. To the extent possible, BioPro shall verify counts and identify any
damages to Valera within five (5) Business Days of receipt. BioPro's sole and
exclusive remedy for any shortage in a shipment shall be for Valera to send
additional units of the Product as soon as reasonably possible.

          6.5.2. REJECTION NOTICE.  A written notice of rejection shall be
conclusive and binding upon Valera unless Valera notifies BioPro within
forty-five (45) Business Days after receipt by Valera of the written notice of
rejection that it denies responsibility for the problem in question. In the
event of such a notice by Valera, the claim shall be settled as set forth in
Sections 8.3 and 8.4.

     6.6 VALERA'S PRODUCT LIABILITY INSURANCE.  Valera agrees to maintain

Upon request by Valera, BioPro will provide Valera with a certificate of
insurance attesting to the existence of such insurance. BioPro shall name Valera

     7.5 FAILURE TO ACHIEVE MINIMUM NET SALES.

Valera shall have the option of (i) converting all of the exclusive rights
granted to BioPro in this Agreement into non-exclusive rights effective as of
the date of BioPro's notice to Valera or such later date as Valera may specify
or (b) terminating this Agreement effective as of the date of BioPro's notice to

Wall Street Journal on the last day of the relevant Calendar Quarter. Unless
otherwise agreed by Valera, BioPro shall obtain a confirmed, irrevocable letter

respect thereof may be properly ascertained.

expense, to permit an independent accounting firm selected by Valera or The
Population Council to have access, upon reasonable notice, during ordinary
business hours and no more frequently than once in any Calendar Year, to such
books of account and other records as may be necessary to determine the
correctness of any report by BioPro made in accordance with this Article 7. If
such independent certified public accountant shall determine that an amount is
due and owing by one Party to the other, then the owing Party shall promptly pay
the amount due and owing; provided that if the Party owing the amount is BioPro
and such amount is five percent (5%) or more of the total amount that should
have been paid under this Agreement in respect of the audited period, then
BioPro shall also reimburse Valera for the cost of the audit.

warranty claim, BioPro shall at BioPro's expense return the allegedly defective
the Products(s), or a representative sample thereof, together with a description
of the alleged defect. Valera shall, promptly after receipt and as required,
inspect the alleged defective Products(s). If such inspection results reasonably

thereof, along with a reference batch which has previously been shown by BioPro
to conform to the warranties set forth in Section 8.1, to a mutually acceptable
independent laboratory along with mutually agreeable interrogatories to be
answered by such laboratory. The determination of the Products' conformance or
non-conformance to the warranties set forth in Section 8.1 shall be binding upon
the Parties. If the laboratory determines that the Products conform to the
warranties set forth in Section 8.1, BioPro shall pay all independent laboratory

refund or credit the Transfer Fee for, any of the Products that do not comply
with Valera's limited warranty set forth in Section 8.1 and reported, to Valera
during the Warranty Period (and confirmed to be defective pursuant to Section
8.3). Valera's obligation to replace defective Product or to refund or credit
the purchase price paid for such the Products pursuant to this Section 8.4 shall
not apply to any Product that has been subjected to misuse, mishandling, storage
in a manner inconsistent with Valera's directions, neglect, modification or
unusual physical or chemical stress after delivery to the carrier. Other than
with respect to third party claims for which Valera must indemnify BioPro
pursuant to Section 10.2, this Section 8.4 states BioPro's sole and exclusive
remedy for failure of any the Products to comply with the limited warranties set
forth in Section 8.1.

     10.1 BY BIOPROS.  BioPro shall indemnify Valera, its affiliates and their
respective directors, officers, shareholders, employees or agents (collectively,
the "VALERA RELEASEES"), and hold it harmless from and against any and all
Losses (including personal injury, death or property damage) arising from any
and all Third Party claims against the Valera Releasees: (a) relating to the
marketing, distribution or sale of the Product in each country of the Territory;
(b) of any nature whatsoever relating to any processing or repackaging of the
Product after delivery to the carrier in accordance with Section 6.4; or (c)
caused by a breach or misstatement by BioPro of its representations and
warranties under this Agreement; except, in each case, to the extent such Third
Party claims result from the fault, negligence or willful misconduct of the
Valera Releasees or its or their material failure to comply with the terms of
this Agreement. BioPro shall not be liable under this Section 10.1 in the event
that the Valera Releasees admit or settle any such claim without the prior
written consent of BioPro, which consent shall not be unreasonably withheld,
conditioned, delayed or denied.

     10.2 BY VALERA.  Valera shall indemnify BioPro, its Affiliates and their
respective directors, officers, shareholders, employees or agents (collectively,
the "BIOPRO RELEASEES"), and hold it harmless from and against any and all
Losses (including personal injury, death or property damage) arising from any
and all Third Party claims against the BioPro Releasees: (a) that the
manufacture, use or sale of the Product in accordance with this Agreement
infringes the intellectual property rights of a third party in each country of
the Territory; (b) of any nature whatsoever relating to the manufacture of the
Product; or (c) caused by a breach or misstatement by Valera of its
representations and warranties in Section 9.1; except, in each case, to the
extent such Third Party claims result from the fault or negligence of the BioPro
Releasees, or its or their material failure to comply with the terms of this
Agreement. Valera shall not be liable under this Section 10.2 in the event that
the BioPro Releasees admit or settle any such claim without the prior written
consent of Valera, which consent shall not be unreasonably withheld, delayed or
denied.

     10.3 INDEMNIFICATION PROCEDURE.  A Party seeking indemnification (the
"INDEMNIFIED PARTY") shall notify, in writing, the other Party (the
"INDEMNIFYING PARTY") within fifteen (15) Business Days after the assertion of
any claim or discovery of any fact upon which the Indemnified Party intends to
base a claim for indemnification. An Indemnified Party's failure to so notify
the Indemnifying Party shall not, however, relieve such Indemnifying Party from
any liability under this Agreement to the Indemnified Party with respect to such
claim except to the extent that such Indemnifying Party suffers or otherwise
incurs additional liquidated or other readily quantifiable damages as a result
of being denied, during the period of delay in notice, the opportunity to remedy
or otherwise mitigate the event or activity giving rise to the claim for
indemnification or the damages therefrom or is materially prejudiced in the
defense of the claims giving rise to the right to indemnification.

     10.4 DEFENDING CLAIMS.  The Indemnifying Party, while reserving the right
to contest its obligations to indemnify the Indemnified Party under this
Agreement, shall be responsible for the defense of any claim, demand, lawsuit or
other proceeding in connection with which the Indemnified Party claims
indemnification hereunder. The Indemnified Party shall have the right, at its
expense, to participate jointly with the Indemnifying Party in the defense of
any such claim, demand, lawsuit or other proceeding, but with respect to any
issue involved in such claim, demand, lawsuit or other proceeding with respect
to which the Indemnifying Party has acknowledged its obligation hereunder, the
Indemnifying Party shall have the right to select counsel, settle, try or
otherwise dispose of or handle such claim, demand, lawsuit or other proceeding
on such terms as the Indemnifying Party shall deem appropriate, subject to any
reasonable written objection of the Indemnified Party.

                   ARTICLE 11 - INTELLECTUAL PROPERTY MATTERS

     11.1 INTELLECTUAL PROPERTY INFRINGEMENT.

          11.1.1. Without limiting the obligations and requirements of Sections
10.2 through 10.4, each Party will notify the other Party if it receives any
notice that the activities engaged in under this Agreement infringe or may
infringe any Third Party's intellectual property rights. If BioPro establishes
to Valera's reasonable satisfaction that license(s) under such Third Party's
intellectual property rights is necessary or advisable for purposes of enabling
BioPro to market, use or sell the Products in each country of the Territory,
Valera and BioPro shall cooperate to obtain such license(s) for the benefit of
Valera and BioPro, in accordance with the following provisions:

          11.1.2. Valera shall be primarily responsible for obtaining any such
third party license. The matter shall be deemed resolved if Valera is granted a
license, whether royalty-free or royalty-bearing, under the relevant
intellectual property rights that would make the continued marketing, use or
sale of the Products in each country of the Territory for use in the Primary
Indication non-infringing with respect to such Third Party's intellectual
property rights.

          11.1.3. However, in the event that Valera is unable to resolve the
matter in accordance with Section 11.1.2 in spite of good faith efforts and/or
upon terms that are commercially reasonable to Valera, then BioPro shall be
entitled to negotiate a license in favor of BioPro under such Third Party's
intellectual property rights, provided that BioPro shall not enter into such
license without the prior written consent of Valera, such consent not to be
unreasonably withheld or delayed. In the event that such license requires BioPro
to pay the Third Party royalties, BioPro may deduct such royalties from the
amounts due to Valera under Section 7.2.2, such deduction not to exceed an
amount equal to two percent (2%) of Net Sales during the applicable Calendar
Quarter.

          11.1.4. Should any claim or suit that the Product infringes any Third
Party's intellectual property rights in each country of the Territory be upheld
by a final, non-appealable order of a court such that BioPro is prevented from
marketing, using and selling the Product in each country of the Territory and no
license that permits BioPro to market, use and sell the Product in each country
of the Territory in accordance with this Agreement is obtained by either Valera
or BioPro pursuant to Sections 11.1.2 and 11.1.3, Valera shall repurchase from
BioPro, at

<PAGE>
                                                                              21


cost, all of the Product currently in BioPro's stock that have not been sold
and, if commercially reasonable to Valera, change the Product so as to make it
non-infringing. If changing the Product so as to make it non-infringing is not
commercially reasonable to Valera, Valera may terminate this Agreement effective
upon giving BioPro notice of termination without any liability to BioPro.

     11.2 THIRD PARTY INFRINGEMENT.

          11.2.1. In the event that either Party determines that a Third Party
(other than a permitted licensee, transferee or distributor of either Party) is
making, using, or selling a product or process that may infringe any of the
Intellectual Property relating to the Product, including later issued and
acquired patents covering the Product, or any uses or processes pertaining
thereto, it will promptly notify the other Party in writing.

          11.2.2. Valera shall be responsible for, in its sole discretion,
obtaining a discontinuance of any infringement or bringing suit against a Third
Party infringer relating to the Product. Notwithstanding anything contained
herein to the contrary, Valera shall have the right, but not the obligation, to
bring such a suit. Valera shall bear all the expenses of any such suit brought
by it and shall, after retaining for itself an amount equal to such expenses,
split equally the remaining balance of any and all recovery and damages
therefrom with BioPro. BioPro agrees to be named as a co-plaintiff if Valera
brings suit and shall cooperate with Valera (which shall include providing any
necessary assistance and executing any necessary documents, with any reasonable,
receipted out-of-pocket expenses being reimbursed to BioPro by Valera to the
extent such expenses were previously approved in writing by Valera), and shall
have the right to consult with Valera and to participate in and be represented
by independent counsel in such litigation at its own expense. Except as
otherwise specifically provided herein, Valera shall have control over any such
suit, and decisions as to settlement, methods and/or terms and conditions for
resolving the suit shall be made by Valera (after consultation with BioPro,
should BioPro be joined as a party to such suit).

                          ARTICLE 12 - CONFIDENTIALITY

     12.1 CONFIDENTIAL INFORMATION.  For the purposes of this Agreement,
"CONFIDENTIAL INFORMATION" means all verbal, written, electronically transmitted
and/or machine reproduced information, chemical structures, data, documents,
methods and Intellectual Property of or relating to the business of either Party
or its Affiliates, already provided or disclosed by it or its Affiliates to the
other Party, or which will be provided to the other Party under this Agreement,
and all materials, data, results, reports and other documents generated by or on
behalf of the other Party containing or regarding such information, data,
documents, methods and Intellectual Property.

     12.2 OBLIGATIONS.  During the Term, each Party may supply to the other
Party such Confidential Information as is considered useful solely for the
purpose of enabling the other Party to perform its obligations hereunder (the
"PURPOSE"). The other Party shall not use or allow the use of the Confidential
Information for any purpose other than the Purpose or to enforce its rights
under this Agreement.

     12.3 EXCEPTIONS.  Neither Party shall have any obligation of non-disclosure
or non-use hereunder with respect to any Confidential Information which:

               (a) at the time of disclosure to the other Party is already
available or known, to the public;

               (b) after disclosure to the other Party becomes available or
known to the public through no breach of this Agreement;

               (c) is already lawfully in the possession of the other Party at
the time disclosure hereunder was made and such possession is documented by
written evidence and not subject to any obligation of non-disclosure or non-use;
or

               (d) is received from a Third Party having the right to disclose
same and who is not bound by obligations of non-disclosure and/or non-use.

     12.4 COMPELLED DISCLOSURE.  If a Party shall become compelled by any
requirement of law or pursuant to any legal, regulatory or investigatory
proceeding before any court, tribunal or other governmental entity, agency or
commission to disclose Confidential Information of the other Party, such Party
shall give the other Party prompt written notice of its receipt of the order or
notice requiring the disclosure so that the other Party may seek a protective
order or other remedy to protect the confidentiality of the Confidential
Information and/or waive the compelled Party's obligations under this Article
12. If such protective order, other remedy or waiver is not obtained or granted
by the time the compelled Party is required to comply, the compelled Party may
furnish only that portion of the Confidential Information of the disclosing
Party that it is compelled to disclose and no more.

     12.5 UNAUTHORIZED USE.  In case either Party becomes aware or has knowledge
of any unauthorized use or disclosure of Confidential Information, it shall
promptly notify the other Party of such unauthorized use or disclosure and,
thereafter, shall take all reasonable steps to assist the other Party in
attempting to minimize any potential or actual damages or losses resulting from
such unauthorized use or disclosure.

     12.6 RETURN OF DOCUMENTS.  Each Party, upon receipt of a written request
from the other Party following the expiration or termination of this Agreement,
shall promptly return to the other Party all Confidential Information of such
other Party, including all reproductions and copies thereof together with all
internal material and documents generated by it containing Confidential
Information or references thereto or from which references the substance of the
Confidential Information can be implied or understood and shall delete all
references thereto stored electronically.

     12.7 OWNERSHIP RIGHTS.  Each Party agrees that it shall not claim to have
any rights, title or ownership in the Confidential Information of the other
Party or any discoveries or inventions based on or derived from the Confidential
Information, and that rights, title and ownership in the Confidential
Information or any discoveries or inventions based on or derived from said
Confidential Information shall, as between the Parties, rest in the disclosing
Party. Each party agrees to promptly disclose to the disclosing Party any
discoveries or inventions based on or derived from the Confidential Information.
Each Party further agrees to assign (and

all such discoveries and inventions and to sign all documents and do all things
required to give effect thereto.

     13.1 TERM.  This Agreement shall commence upon the Effective Date and shall
continue for ten (10) years after the date on which the first Regulatory

reasonably possible within thirty (30) Business Days, fails to propose a plan

reasonably, is capable of providing a remedy of the breach within ninety (90)
Business Days.

               (b) If either Party shall commence as debtor any proceedings
under any bankruptcy, insolvency, readjustment of debt, dissolution or
liquidation Law or any such proceeding shall be commenced against either Party,
or any trustee or receiver shall be appointed therefor, and either Party shall

stated in the Plan for such country for the filing of all such Marketing
Approval Applications for such Indication.

     13.3 PARTIAL TERMINATION.  In the event that any termination of this
Agreement is limited to one (1) or more, but not all forms or dosages of the
Product, or to a country or Indication, then the effects of such termination

designee of all Marketing Approval Applications and all related registrations
and product numbers for the Product and any other Regulatory Approval held with
respect to the Product (in each case whether in BioPro's name or the name of any
Affiliate of BioPro); provided that if this Agreement is only terminated as to a
particular country or Indication, then only the assignment of all Marketing
Approval Applications and all related registrations and product numbers for the
Product and any other Regulatory Approval held with respect to the Product (in
each case whether in BioPro's name or the name of any Affiliate of BioPro) for

               (b) expropriation, confiscation or requisitioning of facilities,
compliance with any Law not presently existing, or change in the interpretation
of any presently existing Law which affects to a degree not presently existing
the supply, availability, export or use of the Product, materials or labour;

               (c) acts or inaction on the part of any Governmental Body or
Person purporting to act therefor;

               (d) embargoes, or acts of war or the public enemy, whether war be
declared or not;

               (e) strikes, public disorder, insurrection, rebellion, riots or
violent demonstrations;

               (f) floods, earthquakes, lightning, hail, inclement weather
conditions or other natural calamities; and

               (g) any circumstances whether or not of the class or kind
specifically named above not within the reasonable control of a Party and which,
despite the exercise of reasonable diligence, such Party is unable to prevent,
avoid or remove including demand that exceeds Valera's supply of the Product.

     14.2 PROCEDURE.  If any Party wishes to invoke an Event of Force Majeure,
then it shall (i) promptly following the commencement of such Event of Force
Majeure notify the other Parties of the occurrence of such Event of Force

nature of the Event of Force Majeure, and (ii) as soon as reasonably practicable
thereafter, submit to the other Parties proof of the Event of Force Majeure.

     14.3 SUSPENSION OF OBLIGATIONS.  If one of the Parties is unable to perform
its obligations under this Agreement because of an Event of Force Majeure, then
such Party shall be excused from performance of its obligations under this
Agreement until the Event of Force Majeure terminates and the obligations of
such Party, which cannot be met due to the Event of Force Majeure, shall be
suspended during the pendency of the Event of Force Majeure; provided that such
Party uses all reasonable efforts to attempt to prevent, avoid or remove the
Event of Force Majeure within the shortest possible delay. Nevertheless, an
Event of Force Majeure has no effect on the obligation to pay a sum of money
owing for the purchase of the Product.

     14.4 RESOLUTION.  If either Party is excused from performance under this
Agreement because of an Event of Force Majeure, then the Parties agree to
promptly meet and to work in good faith together in an attempt to find
appropriate solutions and to shorten the duration of the Event of Force Majeure,
