written notice (the "Canada Notice") to such effect. ASTA Medica shall have a
right of first offer to negotiate with BioNumerik to obtain a license with
respect to the Product(s) in the territory of Canada. The first offer right
granted herein will expire 45 days after ASTA Medica's receipt of the Canada
Notice. If no proposal to obtain a license with respect to the Product(s) for
the territory of Canada is made to BioNumerik by ASTA Medica within such 45 day
period, ASTA Medica's right of first offer shall terminate. In the event ASTA

Know-How, and BioNumerik Improvements in the Territory without cost for internal
research and development purposes, for purposes of co-developing the Product(s)
in the Territory with ASTA Medica as approved by the Alliance Steering
Committee, for purposes of manufacturing the Product(s) in the Territory in
accordance with this Agreement, and for purposes that do not relate to the
Product(s). In addition, BioNumerik, its Affiliates, and other parties
previously or hereafter authorized by BioNumerik shall retain the right to
conduct and have conducted research and development (including studies and
clinical trials) of the Product(s) throughout the world for the purpose of (a)
obtaining regulatory approvals outside the Territory, and (b) obtaining
additional data and information regarding the Product(s). BioNumerik will not
conduct any such research and development in the Territory without the prior
consent of ASTAMedica, which consent will not be unreasonably withheld.
BioNumerik may continue to conduct its existing preclinical studies and Phase I
clinical trials relating to the Product(s) in the Territory. In addition,
nothing contained herein is intended to limit the right of ASTA Medica or
BioNumerik to discover, develop, market, or sell other therapeutic products or
technologies throughout the world.

meet at least quarterly (in Europe, U.S., or by telephone, video conference or
internet - by mutual consent) each calendar year prior to commercialization of
the Product(s) in the Territory. In addition, either Party may request
additional meetings as reasonably required. The Co-Chairs of the Alliance
Steering Committee will be responsible for providing an agenda for each meeting
of the committee at least 10 days in advance of such meeting and shall prepare

                  3.3 Additional Teams and Assistance. The Alliance Steering
Committee may establish such other teams or working groups, as it deems
necessary or desirable in connection with the development and commercialization
of the Product(s).

                  3.4 Cooperation. Each Party will utilize its reasonable best
efforts to act reasonably and in good faith to avoid deadlocks at either the
Alliance Steering Committee or Project Team level and to ensure the successful
operations of both the Alliance Steering Committee and the Project Team. To this
end, each Party will make available to both the Alliance Steering Committee and
the Project Team that Party's knowledge and expertise with regard to the
Product(s) and to the development and registration of products of this nature.

                  3.5 Voting and Dispute Resolution. Each of ASTA Medica and
BioNumerik shall have one vote on the Alliance Steering Committee and on the
Project Team. A unanimous vote by both Parties shall be required for a decision
by the Alliance Steering Committee or the Project Team. A quorum of the Alliance
Steering Committee or the Project Team shall exist only if at least one
representative from each Party with authority to cast the vote of the Party on
the matter before the Alliance Steering Committee or the Project Team, as the
case may be, is present. If the Project Team is unable to reach a decision on
any matter, the Project Team shall refer such matter to the Alliance Steering
Committee. If the Alliance Steering Committee is unable to reach a mutual
agreement on any matter, including any matter referred to the Alliance Steering
Committee by the Project Team, the Alliance Steering Committee shall promptly
conduct good faith discussions in an effort to resolve such matter in a
reasonable and mutually satisfactory manner. If the matter is not resolved by
the Alliance Steering Committee representatives of BioNumerik and ASTA Medica
within 60 days after the commencement of such discussions, either Party may
request, in writing, that the matter be resolved by binding arbitration in
accordance with the provisions of Article 20.9 of the Agreement.

                  3.6 Costs of Maintenance and Operation. Each of ASTA Medica

clinical tests or studies required by any applicable regulatory agency in the
Territory, including any associated manufacturing costs. [**]. BioNumerik is
free to have the calculation of such costs audited in the same manner as
provided in the last sentence of Section 5.6. If BioNumerik determines to
conduct a clinical study for the Product(s) in the Territory on its own, after
obtaining ASTA Medica's consent, BioNumerik shall pay the costs of such study,
unless otherwise agreed by the Parties. If ASTA Medica determines to conduct a
clinical study for the Product(s) outside of the Territory on its own, after
obtaining BioNumerik's consent, ASTA Medica shall pay the costs of such study,
unless otherwise agreed by the Parties.

                  4.2 Government Approvals and Clinical Trials.

                           4.2.1. ASTA Medica agrees at its sole expense to (a)
conduct or cause to be conducted all clinical trials and other studies of any
nature of the Product(s) necessary or desirable for obtaining Government
Regulatory Approvals and (b) prepare and submit all documents necessary or
desirable for obtaining Government Regulatory Approvals. The Alliance Steering
Committee will mutually determine the priority of each country in the Territory
for development, registration and marketing of the Product(s) within a
reasonable period of time following the date of this Agreement. The Alliance
Steering Committee will update the priority list on a semi-annual basis. In
connection therewith, ASTA Medica shall, at its own expense and in accordance

Regulatory Approvals process on a current basis and furnish BioNumerik upon
BioNumerik's reasonable request with copies of all of the documents, data and
other information supplied to or received from applicable government authorities
in connection with the applications for the Government Regulatory Approvals.
Upon receipt of the Government Regulatory Approvals, ASTA Medica shall promptly
furnish BioNumerik copies or other satisfactory evidence thereof. In addition,
ASTA Medica may conduct research and development (including studies and clinical
trials) of the Product(s) outside the Territory for the purpose of supporting
the development and commercialization of the Product(s) in the Territory.
BioNumerik will have the right to review and consent to any such studies and
clinical trials outside the Territory in advance of their commencement, which
consent will not be unreasonably withheld.

                           4.2.2 ASTA Medica shall have ownership (including
reservation of the right to use in the Territory in accordance with this
Agreement) of all data and results obtained by ASTA Medica from the non-clinical
studies, clinical trials and related testing conducted pursuant to Section 4.1
and 4.2.1 (the "ASTA Medica Data and Results"). Each of ASTA Medica and
BioNumerik shall have the right to use the ASTA Medica Data and Results as
described in this Agreement, unless otherwise agreed by the Parties hereto. ASTA
Medica shall also have the right to use data and results obtained by BioNumerik
from the non-clinical studies, clinical trials and related testing conducted for
the Product(s) outside the Territory, provided that such use by ASTA Medica
shall be for the purpose of supporting the development and commercialization of
the Product(s) in the Territory and shall be subject to any existing limitations
on the ability of BioNumerik to provide such data and results to ASTA Medica.

                  4.3 Development Plan and Budget. The initial Development Plan
and initial Budget agreed to by the Parties will be developed by the Parties
with final review and approval by the Alliance Steering Committee. The
Development Plan and Budget will be updated by the Alliance Steering Committee
on at least a quarterly basis. Prior to the start of each calendar year, the
Alliance Steering Committee shall meet to review and approve a Development Plan
and Budget for the following calendar year. No material deviations (e.g., major
changes in clinical study design, patient populations, clinical trial endpoints,
or the analysis of such endpoints) from the Development Plan or Budget will
occur without prior approval by the Alliance Steering Committee. The Development
Plan will include the following elements: (a) a clinical trial program for the
Product(s) in the Territory, (b) a Product Registration Plan, (c) a Publication
Plan, and (d) a Distribution, Selling and Marketing Plan for the Product(s). No

Section 5.6), and country specific-profit and loss estimates.

                  4.4 Promotional Materials involving BioNumerik and Labeling.
To the extent permissible by law, the Product(s) distributed in the Territory
shall be represented in all labeling and other documentation as jointly
developed by ASTA Medica and BioNumerik. ASTA Medica shall assure inclusion,
consistent with the laws of each country in the Territory, of BioNumerik's name,
logo and other identification in any promotional materials, which inclusion
shall be overseen at the Alliance Steering Committee level. ASTA Medica agrees
that promotional materials for the Product(s) in the Territory shall contain the
statement: " Under license from BioNumerik Pharmaceuticals, Inc." and shall also
display the BioNumerik trademark wherever permitted by law. Product(s) marketed
and sold by ASTA Medica hereunder shall also be marked with appropriate patent
numbers or indicia at BioNumerik's request, subject to ASTA Medica's consent,
not to be unreasonably withheld.

         5. LICENSE FEES AND ROYALTIES.

                  5.1 License Fees.

                  5.3 Expiration of Royalty Obligations. The royalty obligations
set forth in Section 5.2 above shall expire on a country-by-country basis in
those countries in which a BioNumerik Patent Right covers the use or sale of
Product(s), effective as of the date upon which the use or sale of Product(s) in
such country would no longer infringe a valid claim of a BioNumerik Patent Right
in the absence of the rights granted hereunder, provided however that (a) all
royalty obligations shall continue on a country-by-country basis until the last
patent expiry of [**] and (b) all royalty obligations shall continue during the
time that any patent application included in the Patent Rights is being
prosecuted. If a new patent is issued in a particular country with respect to

                  5.6 Forecast Adjustment. Within 45 days after the end of each
Fiscal Year the payments according to the forecasts will be compared with the
actual [**]. If the aggregate estimated payments made by ASTA Medica to
BioNumerik for such year exceed the actual royalty owing for such year,
BioNumerik shall refund the difference within 45 days of such determination. If
the aggregate estimated payments made by ASTA Medica to BioNumerik for such year
are less than the actual royalty owing for such year, ASTA Medica shall pay
BioNumerik the difference within 45 days of such determination. ASTA Medica's
accountant, KPMG, will review all data and calculations of royalty amounts and
payments. This will be done no later than the end of February of the following
Fiscal Year. In addition, the records maintained by ASTA Medica for calculating

Pharma agrees to share with ASTA Medica all data and information generated by KI
Pharma with respect to the Product(s) for the purpose of supporting the
development of the Product(s) in the Territory, then ASTA Medica will, on
similar terms, agree to share with [**] all data and information generated by

of the Product(s) in areas outside the Territory will provide that the licensee
under such license will share with ASTA Medica all data and information
generated by such licensee with respect to the Product(s) for the purpose of
supporting the development of Product(s) in the Territory. In the event a
prospective licensee for the commercial distribution of the Product(s) in areas

Medica with all supplies of Product(s) required by ASTA Medica in order to
conduct the pre-commercialization studies and clinical trials described in
Sections 4.1 and 4.2, which supplies shall be furnished by BioNumerik to ASTA
Medica at a price equal [**].

                  7.4 Commercial Supply Agreement. Following execution of this
Agreement, BioNumerik agrees to finalize its processes for the manufacture of
Product(s) as shall be agreed from time to time between itself and ASTA Medica.
Within 24 months prior to the estimated time of the first commercial sale of
Product(s) in the Territory, ASTA Medica and BioNumerik shall enter into a
commercial supply agreement (the "Supply Agreement") to be negotiated in good
faith and to reflect such terms and conditions as shall be reasonably necessary
to govern the manufacture and supply of Product(s) for sale and distribution in
the Territory.

         The Supply Agreement will provide among other things that:

                  (a) Not later than the end of each calendar year that
commences after execution of the Supply Agreement, ASTA Medica will supply to
BioNumerik an estimate of its requirements of the amount of API or finished
Product(s) in the Territory during the following [**] years, and will update
this estimate at six-month intervals. BioNumerik will notify ASTA Medica within
90 days of receipt of such estimate if it (or its Affiliates) will be unable to
supply the whole or any part of the requirements described in such estimate.
Together with the [**] estimate, ASTA Medica will deliver to BioNumerik firm
orders for its estimated requirements of Product(s) not less than 12 months in
advance of the required date of delivery. Within thirty (30) days of its receipt
of such firm order, BioNumerik shall confirm such order in writing and fulfill
such orders in accordance with ASTA Medica's required date of delivery provided
the quantities specified therein do not exceed those quantities contained in the
previous estimate for the same period and provided that BioNumerik has not
previously advised ASTA Medica that it will be unable to supply all or part of
such quantities.

                  (b) If BioNumerik (or its Affiliates) are unable to meet the
requirements of ASTA Medica and its Affiliates and sublicensees for commercial
quantities of Product(s), then ASTA Medica may fill all of its remaining supply
requirements in excess of the amount provided by BioNumerik (and its Affiliates)
from a third party or parties. In such event, (i) BioNumerik shall grant a
license to ASTA Medica under the BioNumerik Patent Rights, BioNumerik Know-How,
and BioNumerik Improvements to manufacture and have such third party manufacture
Product(s) for the purpose of allowing such remaining supply requirements to be
filled, and (ii) BioNumerik shall also provide such information and reasonable
assistance as may be necessary to allow such third party to manufacture
Product(s) for the purpose of allowing such remaining supply requirements to be
filled.

                  (c) The cost of the Product(s) under the Supply Agreement will
be based on [**].

                  (d) ASTA Medica shall be entitled to have BioNumerik's cost of
manufacture and overhead confirmed by an independent firm of accountants to
which BioNumerik has no reasonable objection, but not more than once in any 12
month period, provided, however, that such firm of accountants shall only report
to ASTA Medica the amount of such costs, including overhead, and shall keep
confidential all other information acquired in the course of the examination.
ASTA Medica shall pay the cost of any such audit and the audit shall be
conducted so that it will not disrupt BioNumerik's ongoing business activities.

         The Parties in good faith shall negotiate all other terms of supply and
purchase to be included in the Supply Agreement.

                  7.5 No Infringing Manufacture or Supply. In any event,
BioNumerik shall not be required to manufacture or supply Product(s) pursuant to
this Agreement if by so doing it would be liable to suit for infringement or
contributory infringement of the intellectual property rights of a third party.

the Territory (regardless of which Party actually receives such recovery) shall
be applied first in or toward satisfaction of all out of pocket expenses borne
by ASTA Medica and BioNumerik proportionately in connection with such Suit or
Other IP Litigation. If any surplus remains it shall be divided equally between
ASTA Medica and BioNumerik, provided that in the event that only one of the
Parties is responsible for the prosecution of a Suit or Other IP Litigation,
then the recoveries from such Suit shall be solely awarded or paid to such
Party.

                           (d) Each of ASTA Medica and BioNumerik shall give the
other Party full and complete access to all information such other Party
reasonably requests related to such Suits or Other IP Litigation

                           10.1.1 BioNumerik will use reasonable best efforts to
obtain one global trademark to be used for the Product(s), which is defined in
this Agreement as the "Product Trademark". BioNumerik will inform ASTA Medica at
intervals about the efforts of obtaining the Product Trademark. The choice of
Product Trademark will be made by mutual agreement of BioNumerik and ASTA
Medica. In addition to the foregoing, ASTA Medica will check its pool of
protected trademarks and will provide BioNumerik with potential Product
Trademark proposals if available. If ASTA Medica and BioNumerik select a
trademark for the Product(s) that is owned by ASTA Medica, ASTA Medica shall
grant and hereby does grant BioNumerik an exclusive royalty-free perpetual
paid-up license (with the right to sublicense) to use such trademark in all

Product(s) that is owned by BioNumerik, BioNumerik shall grant and hereby does
grant ASTA Medica an exclusive royalty-free perpetual paid up license (with the
right to sublicense) to use such Product Trademark in all parts of the
Territory. Should no global Product Trademark be available or should a given
trademark be available but not be acceptable in some jurisdiction (e.g. for
linguistic reasons), the Parties will seek and reach agreement on an alternative
trademark for such jurisdiction. The ownership, use and licensing of such
alternative trademark shall be governed by the same provisions as those
contained herein regarding the ownership, use, and licensing of the Product
Trademark

                           10.1.2 BioNumerik agrees to register and maintain the
Product Trademark at the expense of BioNumerik for use in and association with
Product(s) and such other Trademarks in the Territory in respect of the
Product(s) as ASTA Medica and BioNumerik shall approve. ASTA Medica agrees

selected from the ASTA Medica pool, as expressly provided in Section 10.1.1
above, and for the name and housemark (logo) "ASTA Medica" both in word and
word-and-design form, BioNumerik shall be the exclusive owner of all registered
and unregistered trademarks and/or service marks associated with the Product(s)
(collectively, "BioNumerik Related Trademark Rights"), including, but not
limited to the Trademarks and the "BioNumerik" name and housemark (logo).

                           10.1.4 BioNumerik shall remain free to use and grant
rights to the use of the Trademarks (a) outside of the Territory and (b) inside
of the Territory with respect to the "BioNumerik" name and housemark (logo) in
connection with products, activities and uses other than the sale and
distribution of Product(s).

                           10.1.5 ASTA Medica acknowledges the validity of the
BioNumerik Related Trademark Rights in the Territory. ASTA Medica shall take due
care not to do or cause to be done any action or omission which adversely
affects the validity of the BioNumerik Related Trademark Rights or jeopardizes
the maintenance thereof, either during the term of this Agreement or thereafter.

                           10.1.6 BioNumerik acknowledges the validity of the
trademarks selected from the ASTA Medica pool in and outside the Territory.
BioNumerik shall take due care not to do or cause to be done any action or
omission which adversely affects the validity of these trademarks or jeopardizes
the maintenance thereof, either during the term of this Agreement or thereafter.

                           10.1.7 ASTA Medica agrees that it will maintain the
quality control standards for the Trademarks and BioNumerik Related Trademark
Rights set forth by BioNumerik and agreed by ASTA Medica (ASTA Medica shall not
unreasonably withhold such agreement) and will ensure that any sublicensee using
the Trademarks and BioNumerik Related Trademark Rights in the Territory shall be
subject to similar standards of quality control.

or to such other address as either Party may indicate by proper notice to the
other in the same manner as provided herein; provided, however, that the notices
referred to in or required under Sections 9.5 and 14.2. shall be given by
personal delivery, courier service, facsimile, or registered or certified
airmail mentioned above. All notices are deemed effective on the date of receipt
or, if delivery is not accepted, five (5) days after placement with the
addressee, an overnight courier service or a post office, as applicable.

                  20.5 Severability. Should any provision of this Agreement be
held to be invalid, unenforceable, or against public policy, the remaining
provisions hereof shall not be affected thereby. In such event, the Parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the Parties as closely as possible with respect to those
provisions, which were held, to be invalid, unenforceable or against public
policy.

                  20.6 Counterparts. This Agreement may be executed in several
counterparts, each of which will be an original, but all of which, when taken
together, will constitute one and the same instrument.

                  20.7 Warranty Disclaimer. EXCEPT AS EXPRESSLY PROVIDED IN
SECTIONS 9 AND 15, BIONUMERIK MAKES NO WARRANTY WITH RESPECT TO ANY TECHNOLOGY,
GOODS, SERVICES, RIGHTS OR OTHER SUBJECT MATTER OF THIS AGREEMENT AND HEREBY
DISCLAIMS WARRANTIES OF MERCHANTABILITY, SAFETY, AND FITNESS FOR A PARTICULAR
PURPOSE AND NONINFRINGEMENT WITH RESPECT TO ANY AND ALL OF THE FOREGOING. THE
PARTIES UNDERSTAND AND AGREE THAT DEVELOPMENT AND COMMERCIALIZATION OF BNP7787
AND/OR PRODUCT(S) WILL INVOLVE APPROVAL BY REGULATORY AUTHORITIES AND THAT NO
PARTY IS GUARANTEEING THE SAFETY OR EFFICACY OF BNP7787 AND/OR PRODUCT(S) OR
THAT ANY REGULATORY AUTHORITY OR AGENCY SHALL GIVE COMMERCIAL APPROVAL OF
BNP7787 AND/OR PRODUCT(S).

                  20.8 Force Majeure.

                  20.8.1. Except for the payment of money, no failure or
omission by the Parties hereto in the performance of any obligation of this
Agreement shall be deemed a breach of this Agreement nor create any liability,
if the same arises as a result of force majeure, i.e., any cause or causes
beyond the control of the Parties, including, but not limited to the following,
which for the purposes of this Agreement, shall be regarded as beyond the
control of the Party in question: acts of God; acts, omissions, rules,
regulations, or

                                       40

orders of any governmental authority or any officer, department, agency or
instrumentality thereof; flood; earthquake; acts of the public enemy; war;
rebellion; insurrection; riot; invasion; strikes, or lockouts.

                  20.8.2. In the event of such cause intervening, such excuse of
performance shall be only to the extent that such non-performance is beyond the
reasonable control of the Party bound by such covenant or obligation; and the
Party so affected shall use its reasonable best efforts to eliminate or cure or
overcome any of such causes and to resume performance of its covenants and
obligations with all possible speed.

                  20.9 Arbitration. All disputes, controversies or differences
which may arise between the Parties, out of or in relation to or in connection
with this Agreement, or the breach thereof, shall be finally settled by
arbitration, by the International Chamber of Commerce (ICC) Rules in Genf,
Switzerland in the English Language, by a panel of three (3) arbitrators in
accordance with the then current ICC Rules, provided that the arbitrators will
first render a preliminary decision setting forth their grounds for decision and
providing at least thirty (30) days for each of the Parties to respond. The
Parties hereto expressly waive any right to appeal such decision or to challenge
the decision in any court. For purposes of enforcement, the judgment arising
from such arbitration may be entered in any court of competent jurisdiction in
the United States or Germany. This clause shall not be used to prohibit the
right of either Party to seek injunctive relief in appropriate circumstances.

                  20.10 Export Controls. The Parties agree to abide by the
United States laws and regulations governing exports of the Product(s) or any
other technology developed or disclosed as a result of this Agreement. The
Parties acknowledge that any performance under this Agreement is subject to any
restrictions that may be imposed by the United States laws and regulations
governing exports. Each Party agrees to provide the other Party with any
assistance, including written assurances, which may be required by a competent
governmental authority and by applicable laws and regulation as a precondition
for any disclosure of technology by the other Party under the terms of this
Agreement. In addition, the Parties hereto agree to take all actions as may
reasonably be required to assure compliance with all applicable requirements of
the U.S. Foreign Corrupt Practices Act.

                  20.11 Construction/Jurisdiction/Official Language. This
Agreement shall be construed in accordance with the laws of Switzerland. Each
Party hereto hereby irrevocably consents and submits to the jurisdiction of the
courts of the State of Texas and of the United States of America and of Germany
for purposes of enforcing any judgment that arises from arbitration pursuant to
Section 20.9. English shall be the official language of this Agreement and any
related agreement provided for hereunder and all

                                       41
<PAGE>   46

communications between the Parties hereto shall be conducted in that language.
Each Party recognizes that the Parties grant no license, by implication or
otherwise, except for the licenses expressly set forth in this Agreement. ASTA
Medica agrees to promptly provide BioNumerik with written English translations
of all important documents that are not in English and relate to the Product(s)
or this Agreement as may be reasonably requested by BioNumerik.

                  21. USE OF NAMES. The Parties hereto understand that each
Party may disclose certain matters pertaining to this Agreement as required by
applicable securities laws or other applicable laws and regulations, which
disclosure may include the name of the other Party and the subject matter of
this Agreement, and be in the form of public statements, whether oral or
written, including, but not limited to, shareholder reports, communications with
stock market analysts, press releases or other communications with the media.
Each Party agrees to coordinate with the other Party press releases and other
public statements regarding this Agreement and the Parties' relationship with
regard to the Product(s). Press releases and other public disclosure involving
potentially sensitive intellectual property matters, product development or
marketing strategies, clinical trials results or other sensitive information
must receive prior written approval by both Parties, which neither Party will
unreasonably withhold. Coordinated common major press releases will be mutually
agreed to by the Alliance Steering Committee in advance of such press release at
the international level. Local market information and abstracts from the common
press releases are not subject to further approval.

                  22. ENTIRE AGREEMENT. This Agreement comprises the entire
understanding and Agreement of the Parties hereto with respect to the specific
subject matter of this Agreement, and supersedes all prior Agreements or
understandings, written or oral, between the Parties hereto with respect to the
specific subject matter of this Agreement. In addition, those obligations under
the BioNumerik Confidentiality Agreement and the ASTA Medica Confidentiality
Agreement shall continue in full force and effect in accordance with their
terms. This Agreement may not be amended except by a written instrument signed
by the Parties hereto.

                  23. CAPTIONS. The captions used in this Agreement are for
purposes of clarification only and are not meant to be construed as part of this
Agreement.
