                2. RESEARCH.

                           2.1 The  Research  Phase  will  consist of two Ligand
stages and/or two Growth Factor stages, as described below:

                           2.1.1 Prior to the  commencement  of Ligand  Stage 1,
Novo Nordisk will  determine  whether or not the Receptor  sequence  provided by
Progenitor to Novo Nordisk is full-length,  and, if Novo Nordisk determines that
such sequence is not  full-length,  Novo Nordisk will  complete  such  sequence.
During Ligand Stage 1 of the Research Phase,  Novo Nordisk and/or one or more of
its Affiliates will attempt to isolate,  clone and sequence a Ligand pursuant to
the work plan  attached  as  Exhibit  2.1.1.  As  required  by Novo  Nordisk  or
requested by the Joint Committee,  and at no additional charge,  Progenitor will
provide Novo  Nordisk  with samples of cDNA  encoding the Receptor and any other
materials or  assistance  required to enable Novo Nordisk to determine  that the
Receptor  sequence provided by Progenitor to Novo Nordisk is full-length (or, if
Novo Nordisk  determines  that it is not full length,  to enable Novo Nordisk to
complete  such  sequence)  and to carry out Novo  Nordisk's  obligations  during
Ligand  Stage 1. During  Ligand  Stage 1, Novo Nordisk will limit its use of the
Receptor and any related  tools and  reagents  provided to it by  Progenitor  to
carrying out the tasks  contemplated  by this Section 2.1. Novo Nordisk will not
screen the Receptor  against any  material,  or commingle  the Receptor with any
material,  that is the property of any person or entity other than Novo Nordisk,
Progenitor  and/or any  Affiliate  of either such  party,  except with the prior
approval  of the Joint  Committee.  Following  the end of  Ligand  Stage 1, Novo
Nordisk  will not use the  Receptor  except in  connection  with any  Identified
Ligand (as defined  below).  The  parties  anticipate  that Ligand  Stage 1 will
continue for approximately [*********]. If Novo Nordisk has not isolated, cloned
and sequenced a Ligand within  [*********] after the date of the commencement of
Ligand Stage 1,  Progenitor  may deliver  written  notice to Novo Nordisk at any
time after expiration of such [*********]  period but before  completion of such
tasks by Novo Nordisk  demanding that Novo Nordisk complete such tasks within 60
days after delivery of such notice,  and, if Novo Nordisk does not complete such
tasks within such 60-day period, Progenitor may terminate Ligand Stage 1 and the
license  granted to Novo Nordisk  pursuant to this Agreement with respect to the
Receptor  and all Ligands by delivery of written  notice to Novo  Nordisk,  and,
after such termination, Progenitor shall have the rights granted in Section 8.5.
Ligand Stage 1 will begin on the date that Novo Nordisk  notifies  Progenitor in
writing  that:  (i)  Progenitor  has  completed  delivery of the samples of cDNA
encoding  the  Receptor  and other  materials  to be  delivered  to Novo Nordisk
pursuant to this  Section  2.1.1,  and (ii) Novo Nordisk has  possession  of the
full-length  Receptor sequence.  Ligand Stage l will continue until Novo Nordisk
has notified Progenitor in writing that Novo Nordisk has successfully  completed
the tasks of  isolating,  cloning and  sequencing a Ligand (the "Ligand  Stage 1
Termination Date"), or until Ligand Stage

1 or this Agreement is terminated, whichever occurs first. Each determination of
whether or not Novo Nordisk has successfully isolated, cloned and sequenced a
Ligand will be made by Novo Nordisk in its sole discretion, based on some or all
of the criteria set forth in Exhibit 1.9 having been met and based on the
recommendation, if any, of the Joint Committee. Within 60 days after the Ligand
Stage 1 Termination Date, Novo Nordisk will notify Progenitor in writing (the
"Identified Ligand Notice") stating whether or not Novo Nordisk desires to go
forward with Ligand Stage 2 of the Research Phase and what Ligand or Ligands, if
more than one, (or other result of the work conducted pursuant to Ligand Stage
1) Novo Nordisk desires to go forward with (each is referred to herein as an
"Identified Ligand"). If Novo Nordisk states in the Identified Ligand Notice
that it does not desire to proceed to Ligand Stage 2 with any Ligand (or other
result of the work conducted pursuant to Ligand Stage 1), the licenses granted
to Novo Nordisk pursuant to this Agreement with respect to the Receptor and all
Ligands will terminate as of the date of delivery to Progenitor of the
Identified Ligand Notice, and, after such termination, Progenitor shall have the
rights granted in Section 8.5.

                              2.1.2 During Ligand Stage 2 of the Research Phase,
Progenitor  will perform the studies  described  in Exhibit  2.1.2 and will work
with Novo Nordisk to establish the biological function of each Identified Ligand
to Novo Nordisk's  satisfaction.  Progenitor will notify Novo Nordisk in writing
when  Progenitor  is ready to commence  such  activities  (the  "Ligand  Stage 2
Commencement  Notice"),  which notice will be delivered to Novo Nordisk no later
than 30 days after Progenitor's receipt of the Identified Ligand Notice.  Ligand
Stage 2 will  begin  on the  date  Novo  Nordisk  receives  the  Ligand  Stage 2
Commencement  Notice and shall  continue for a period of [********]  thereafter.
Novo Nordisk will be responsible  for producing,  at no additional  charge,  all
recombinant  Identified  Ligand protein required by Progenitor (as determined by
the Joint  Committee)  to complete its tasks during  Ligand Stage 2.  Progenitor
will limit its use of such protein to performance of its obligations  under this
Agreement.  Within 60 days after the end of Ligand  Stage 2, Novo  Nordisk  will
notify Progenitor in writing (the "Ligand  Development  Notice") stating whether
or not Novo Nordisk desires to go forward with development of a Licensed Product
based on an Identified Ligand or any other result of the work performed pursuant
to Ligand Stage 2. If Novo Nordisk states in the Ligand  Development Notice that
it does not desire to proceed with development of any such Licensed Product, the
licenses  granted to Novo Nordisk pursuant to this Agreement with respect to the
Receptor and all Ligands will terminate as of the date of delivery to Progenitor
of the Ligand Development Notice, and, after such termination,  Progenitor shall
have the rights granted in Section 8.5.

                              2.1.3 During Growth Factor Stage 1 of the Research
Phase, Novo Nordisk and/or one or more of its Affiliates will attempt to purify,
clone and sequence a Growth Factor pursuant to the work plan attached as Exhibit
2.1.3. As required by Novo Nordisk, and at no additional charge, Progenitor will
provide Novo Nordisk with samples of Growth  Factor-producing cell lines and any
other materials or assistance  required to enable Novo Nordisk to carry out Novo
Nordisk's  obligations  during Growth Factor Stage 1. During Growth Factor Stage
1, Novo Nordisk will limit its use of all Growth  Factors and any related  tools
and reagents provided to it by Progenitor to carrying out the tasks contemplated
by this Section 2.1. Novo Nordisk will not screen any Growth Factor  provided to
Novo Nordisk by Progenitor

against any material, or commingle any such Growth Factor with any material,
that is the property of any person or entity other than Novo Nordisk, Progenitor
and/or any Affiliate of either such party, except with the prior approval of the
Joint Committee. Following the end of Growth Factor Stage 1, Novo Nordisk will
not use any Growth Factor provided to Novo Nordisk by Progenitor except in
connection with any Identified Growth Factor (as defined below). The parties
anticipate that Growth Factor Stage 1 will continue for approximately
[***********]. If Novo Nordisk has not purified, cloned and sequenced a Growth
Factor within [***********] after the date of the commencement of Growth Factor
Stage I, Progenitor may deliver written notice to Novo Nordisk at any time after
expiration of such [**********] period but before completion of such tasks by
Novo Nordisk demanding that Novo Nordisk complete such tasks within 60 days
after delivery of such notice, and, if Novo Nordisk does not complete such tasks
within such 60- day period, Progenitor may terminate Growth Factor Stage 1 and
the license granted to Novo Nordisk pursuant to this Agreement with respect to
all Growth Factors by delivery of written notice to Novo Nordisk, and, after
such termination, Progenitor shall have the rights granted in Section 8.6.
Growth Factor Stage 1 will begin on the later of the date of this Agreement or
the date that Novo Nordisk notifies Progenitor in writing that Progenitor has
completed delivery of the samples of Growth Factor cell lines and other
materials to be delivered to Novo Nordisk pursuant to this Section 2.1.3 and
will continue until Novo Nordisk has notified Progenitor in writing that Novo
Nordisk has successfully completed the tasks of purifying, cloning and
sequencing a Growth Factor (the "Growth Factor Stage 1 Termination Date"), or
until Growth Factor Stage 1 or this Agreement is terminated, whichever occurs
first. Each determination of whether or not Novo Nordisk has successfully
purified, cloned and sequenced a Growth Factor will be made by Novo Nordisk in
its sole discretion, based on some or all of the criteria set forth in Exhibit
1.3 having been met and based on the recommendation, if any, of the Joint
Committee. Within 60 days after the Growth Factor Stage 1 Termination Date, Novo
Nordisk will notify Progenitor in writing (the "Identified Growth Factor
Notice") stating whether or not Novo Nordisk desires to go forward with Growth
Factor Stage 2 of the Research Phase and what Growth Factor or Growth Factors,
if more than one, (or other result of the work conducted pursuant to Growth
Factor Stage 1) Novo Nordisk desires to go forward with (each is referred to
herein as an "Identified Growth Factor"). If Novo Nordisk states in the
Identified Growth Factor Notice that it does not desire to proceed to Growth
Factor Stage 2 with any Growth Factor (or other result of the work conducted
pursuant to Growth Factor Stage 1), the licenses granted to Novo Nordisk
pursuant to this Agreement with respect to all Growth Factors will terminate as
of the date of delivery to Progenitor of the Identified Growth Factor Notice,
and, after such termination, Progenitor shall have the rights granted in Section
8.6.

                              2.1.4 During Growth Factor Stage 2 of the Research
Phase,  Progenitor will perform the studies  described in Exhibit 2.1.4 and will
work with Novo Nordisk to establish the biological  function of each  Identified
Growth  Factor to Novo  Nordisk's  satisfaction.  Progenitor  will  notify  Novo
Nordisk in writing when  Progenitor  is ready to commence such  activities  (the
"Growth Factor Stage 2 Commencement Notice"),  which notice will be delivered to
Novo Nordisk no later than 30 days after Progenitor's  receipt of the Identified
Growth Factor Notice.  Growth Factor Stage 2 will begin on the date Novo Nordisk
receives the Growth Factor Stage 2 Commencement  Notice and shall continue for a
period of

two years thereafter. Novo Nordisk will be responsible for producing, at no
additional charge, all recombinant Identified Growth Factor protein required by
Progenitor (as determined by the Joint Committee) to complete its tasks during
Growth Factor Stage 2. Progenitor will limit its use of such protein to
performance of its obligations under this Agreement. Within 60 days after the
end of Growth Factor Stage 2, Novo Nordisk will notify Progenitor in writing
(the "Growth Factor Development Notice") stating whether or not Novo Nordisk
desires to go forward with development of a Licensed Product based on an
Identified Growth Factor or any other result of the work performed pursuant to
Growth Factor Stage 2. If Novo Nordisk states in the Growth Factor Development
Notice that it does not desire to proceed with development of any such Licensed
Product, the licenses granted to Novo Nordisk pursuant to this Agreement with
respect to all Growth Factors will terminate as of the date of delivery to
Progenitor of the Growth Factor Development Notice, and, after such termination,
Progenitor shall have the rights granted in Section 8.6.

                              2.1.5  Progenitor  will  devote  no less  than the
equivalent of [**] qualified  scientists  working full-time on completion of its
obligations  throughout  Ligand  Stage 2 and Growth  Factor  Stage 2;  provided,
however,  that  during any period  during  which  Progenitor  is  simultaneously
performing  work in Ligand Stage 2 and Growth  Factor Stage 2,  Progenitor  will
devote no less than the  equivalent  of [******]  qualified  scientists  working
full-time on completion of its obligations hereunder; provided further, however,
that, throughout any period during which Progenitor is simultaneously performing
work in Ligand  Stage 2 and  Growth  Factor  Stage 2, the Joint  Committee  will
consider  whether  or not (i) the tasks to be  completed  by  Progenitor  during
Ligand  Stage 2 and Growth  Factor  Stage 2 justify the devotion of such greater
resources by Progenitor (in terms of additional  qualified scientists working on
the project),  and (ii)  Progenitor has such additional  resources  available to
devote  to  completion  of such  tasks.  If the  Joint  Committee,  in its  sole
discretion,  determines that such additional effort is not justified and/or that
Progenitor  does  not  have  such  additional  resources  available,  the  Joint
Committee  may  authorize  Progenitor  to  devote  less than the  equivalent  of
[******] qualified  scientists working full-time on such project,  in which case
the research fees to be paid to  Progenitor  during such period shall be reduced
as provided in Section 4.1 below.  For  purposes of this  Agreement,  the phrase
"full- time" shall mean forty hours per week, excluding holidays.

                              2.1.6 If Novo Nordisk  determines at any time that
any  Growth  Factor is also a Ligand (or part of a Ligand),  Novo  Nordisk  will
provide  Progenitor with written notice of such  determination,  and such Growth
Factor shall  thereafter be treated as a Ligand (and not as a Growth Factor) for
purposes of this Agreement.

                           2.2  If  Novo  Nordisk  elects  to  go  forward  with
development  of any Licensed  Product,  Novo  Nordisk  and/or one or more of its
Affiliates will attempt through  commercially  reasonable efforts to develop and
commercialize  such  Licensed  Product  and to secure all  necessary  regulatory
approvals in connection  therewith.  Progenitor  acknowledges  that Novo Nordisk
may,  but shall not be  required  to,  begin such  activities  before the end of
Ligand Stage 2, Growth Factor Stage 2 and/or the Research  Phase. As between the
parties,  all results of such efforts by or on behalf of Novo Nordisk and/or its
Affiliates, regardless of when such

efforts are made, shall be owned by Novo Nordisk, and shall not be deemed to be
part of the Joint Technology. Progenitor will assist Novo Nordisk in this effort
as and when reasonably requested by Novo Nordisk. Novo Nordisk does not
guarantee that it will develop, produce or market a Licensed Product or that it
will generate Royalties for Progenitor.

                           2.3 As requested  by Novo  Nordisk,  Progenitor  will
share with personnel of Novo Nordisk, its Affiliates, and their sublicensees and
subcontractors,  to the extent it can do so without  violating any obligation of
Progenitor  and/or any of its  Affiliates  to any third  party  (and  Progenitor
warrants that any such  obligations  existing on the date of this Agreement that
would prohibit  Progenitor from sharing pertinent  materials or information with
Progenitor have been disclosed by Progenitor to Novo Nordisk in writing prior to
the date hereof),  all materials and documents in Progenitor's  possession,  and
all  Progenitor's  knowledge  and know-how,  related to the  Receptor,  Ligands,
Growth Factors, the mammalian cells expressing any of the foregoing,  methods of
isolating  any of  the  foregoing,  the  Licensed  Patent  Rights  and  Licensed
Technology,   including  without  limitation  all  such  materials,   documents,
knowledge and know-how  obtained by Progenitor from any third party,  subject to
the applicable confidentiality provisions contained in this Agreement; provided,
however, that nothing in this Section shall be construed as requiring Progenitor
to  describe  to Novo  Nordisk  the  exact  method  employed  by  Progenitor  in
identifying  the partial cDNA  sequence  disclosed in the United  States  patent
application  filed on  behalf  of  Progenitor  on  [***************],  except as
required  to be  disclosed  to the United  States  Food and Drug  Administration
("FDA") or any other  regulatory  agency in connection with gaining  approval to
market and/or distribute any Licensed Product. As requested by Progenitor,  Novo
Nordisk  will share with  personnel of  Progenitor,  its  Affiliates,  and their
sublicensees and  subcontractors,  to the extent it can do so without  violating
any  obligation of Novo Nordisk and/or any of its Affiliates to any third party,
all materials and documents in Novo Nordisk's possession, and all Novo Nordisk's
knowledge and know-how,  related to the Receptor,  Ligands,  Growth Factors, the
Licensed Patent Rights and Licensed Technology and acquired or developed by Novo
Nordisk and/or its Affiliates in the course of the Research Phase.

                           2.4 The parties hereby establish the Joint Committee,
to be  comprised  of three  representatives  appointed by Novo Nordisk and three
representatives  appointed by Progenitor.  The initial  representatives  of Novo
Nordisk to the Joint Committee shall be Dr. Don Foster,  Dr. John Forstrom,  and
Dr. Luciana Simoncini and the initial representatives of Progenitor to the Joint
Committee shall be Dr. H. Ralph  Snodgrass,  Dr. Doros Platika,  and Dr. Stephen
Williams.  One  representative  from each party  shall be that  party's  project
leader for this  Agreement.  Each party will promptly  notify the other party of
any change in its  appointed  representatives.  In addition,  if any  designated
representative  of a  party  is  unable  to  attend  any  meeting  of the  Joint
Committee,   such  party  may  designate  a  replacement   for  such  designated
representative;  provided, however, that if all three designated representatives
of either  party are unable to attend any meeting of the Joint  Committee,  such
meeting shall be rescheduled.

                              2.4.1 Where the Joint  Committee  is  specifically
authorized by this  Agreement to make  determinations,  any such  determinations
shall be made by majority vote,

and each representative shall have one vote. During the Research Phase, the
Joint Committee shall meet in person at least twice each calendar year and by
teleconference at least once each calendar quarter (excluding the calendar
quarters in which it meets in person). Following the Research Phase, the Joint
Committee shall meet in person or by teleconference at least once each calendar
year. Each party shall bear its own expenses for its personnel attending such
meetings. The representatives of each party shall prepare and distribute to both
parties written minutes of each such meeting, both during and after the Research
Phase, which minutes will, without limitation, describe each recommendation and
determination made by the Joint Committee pursuant to Section 2.1. Such minutes
of each meeting shall be reviewed, amended if necessary and approved at the
following meeting of the Joint Committee, and copies of all such final minutes
shall immediately be distributed to both parties.

                              2.4.2 The  purpose of the Joint  Committee  during
the  Research  Phase shall be: (i) to advise the parties  regarding  the overall
strategy for the Research Phase,  as  contemplated  by this  Agreement;  (ii) to
coordinate  the parties'  activities  hereunder;  (iii) to review all results of
work done in the Research Phase and suggest modifications to the scope and goals
of such work, if the Joint Committee  deems it necessary;  and (iv) to undertake
the responsibilities  and make the recommendations and determinations  delegated
to it pursuant to Section 2.1 of this Agreement.

                              2.4.3  Outside the course of the  Research  Phase,
the role of the Joint  Committee shall be to advise Novo Nordisk with respect to
development  and  commercialization  of Licensed  Product,  as requested by Novo
Nordisk.

                           2.5 All rights in any  partial or  complete  sequence
information describing any Ligand or Growth Factor, and other technology,  data,
information  and  inventions,  whether  or not  patentable,  developed  from the
materials provided to Novo Nordisk by Progenitor  pursuant to this Agreement and
arising  from the  research  conducted by or on behalf of either or both parties
pursuant to this  Agreement in the course of the Research Phase shall be jointly
owned by Novo  Nordisk and  Progenitor.  Work  performed by or on behalf of Novo
Nordisk and/or its Affiliates pursuant to Section 2.2 shall not be considered to
be conducted in the course of the  Research  Phase.  Each party will ensure that
all third  parties  that  conduct any portion of the research to be conducted by
such party or on such party's behalf pursuant to this Agreement sign appropriate
documents  transferring  their rights therein to such party  consistent with the
terms of this Agreement.

                           2.6  Progenitor  acknowledges  that Novo Nordisk may,
now or in the future,  conduct its own  research  and/or  enter into one or more
agreements   with   third   parties   that   involve    identification    and/or
characterization  of  putative  ligands  and/or  receptors  in  general,  and of
cytokine-like ligands and/or receptors in particular. The parties recognize that
such  efforts  on behalf of Novo  Nordisk  may result in  identification  and/or
characterization of a molecule that is identical or substantially similar to the
Receptor, a Ligand or a Growth Factor.  Alternatively,  a molecule discovered by
Novo  Nordisk or obtained by Novo Nordisk from a third party may be a portion of
the Receptor, a Ligand or a Growth Factor, or the Receptor, a Ligand or a Growth

Factor may be a portion of such a molecule. In such case, Novo Nordisk will have
the sole right to determine, in its discretion, which molecule or molecules
(whether a Ligand, a Growth Factor or a molecule discovered by Novo Nordisk or
obtained from a third party), if any, to develop into a product. Except as set
forth in Section 2.5, all technology, data, information and inventions, whether
or not patentable, arising from any research conducted by or on behalf of Novo
Nordisk shall, as between the parties, be the sole property of Novo Nordisk.
Novo Nordisk will not disclose to Progenitor any confidential information
received by Novo Nordisk from a third party, and, as set forth in Section 5
below, Novo Nordisk will not disclose to any third party any confidential
information received by Novo Nordisk from Progenitor. Novo Nordisk will not
intentionally seek a collaboration with any third party with respect to any
molecule that is identical or substantially similar to the Receptor, a Ligand or
a Growth Factor. Novo Nordisk will notify Progenitor in writing within 24 hours
after Progenitor discloses Progenitor's sequence for the Receptor to Novo
Nordisk whether or not Novo Nordisk and/or any of its Affiliates is then working
with any molecule that is identical or substantially similar to the Receptor.

                           2.7  So  long  as  Novo  Nordisk  is  producing   any
Identified Ligand and/or any Identified Growth Factor,  and so long as the Joint
Committee determines that supply of such materials by Novo Nordisk to Progenitor
and its  Affiliates  pursuant  to this  Section  would  not  interfere  with the
development  or  commercialization  of any  Licensed  Product  pursuant  to this
Agreement,  Novo Nordisk will supply  Progenitor with  reasonable  quantities of
such Identified  Ligand and/or Identified Growth Factor, in any form produced by
Novo Nordisk for its own purposes, for use only by Progenitor and its Affiliates
solely in conducting research activities outside the Field. Progenitor shall not
provide any such  materials  to any third party  without Novo  Nordisk's  prior,
written  consent in each  instance.  Any such  materials  shall be  provided  to
Progenitor for no additional charge,  except that Progenitor will reimburse Novo
Nordisk,  as requested by Novo Nordisk,  for any expenses  incurred in packaging
such materials and shipping them to Progenitor. Any and all such materials shall
be provided by Novo Nordisk AS IS AND WITHOUT WARRANTY OF ANY KIND.

                  3.        LICENSE.

                           3.1   Subject   to  the  terms  of  this   Agreement,
Progenitor hereby grants Novo Nordisk and its Affiliates the worldwide, sole and
exclusive  license,  with right to sublicense,  under the Licensed Patent Rights
and Licensed  Technology,  to make, have made,  use, sell, have sold,  offer for
sale and import Licensed Product for use in the Field and to otherwise carry out
its rights and obligations pursuant to this Agreement.

                           3.2  Subject  to the  terms of this  Agreement,  Novo
Nordisk hereby grants Progenitor and its Affiliates the worldwide, royalty-free,
sole and  exclusive  license,  with right to  sublicense,  under Novo  Nordisk's
rights in any Novo Nordisk Patent Rights,  to make,  have made,  use, sell, have
sold, offer for sale and import products for use outside the Field. SUCH LICENSE
IS  GRANTED  AS IS,  WITHOUT  WARRANTY  OF ANY KIND,  AND  PROGENITOR  AGREES TO
INDEMNIFY NOVO NORDISK FOR ANY LOSS,  DAMAGE,  LIABILITY AND EXPENSE,  INCLUDING
WITHOUT LIMITATION ATTORNEYS' FEES

AND COSTS OF DEFENSE, ARISING OUT OF ANY EXERCISE OF SUCH RIGHTS, AND/OR OUT OF
ANY USE OF MATERIALS PROVIDED BY NOVO NORDISK TO PROGENITOR HEREUNDER, BY OR ON
BEHALF OF PROGENITOR, ITS AFFILIATES AND/OR ITS OR THEIR LICENSEES AND
ASSIGNEES, EXCLUDING ANY SUCH LOSS, DAMAGE, LIABILITY OR EXPENSE INTENTIONALLY
CAUSED BY NOVO NORDISK AND/OR ITS AFFILIATES.

                           3.3 Within 15 days after the date of this  Agreement,
Progenitor  will  deliver to Novo  Nordisk all  documentation  regarding  patent
applications  and other  filings  made with the patent  authority of any country
with respect to Licensed Patent Rights.  Progenitor shall have the sole right to
file and prosecute any patent applications relating to the Receptor and its uses
and to maintain such patent rights.  Except as provided in Section 8.5.2,  8.6.2
and 8.7.2,  Novo  Nordisk  shall have the sole right to file and  prosecute  any
patent  applications  giving rise, in whole or in part,  to the Licensed  Patent
Rights,  with the exception of patents and patent  applications  relating to the
Receptor  and its uses,  and to  maintain  patents  under such  Licensed  Patent
Rights.  Each party will  provide the other party with copies of all such patent
applications and amendments filed by it and all other correspondence  between it
and the patent authority of any country  regarding such patent  applications and
amendments.   Each  party  shall  bear  all  expenses  of  the  patent,  filing,
prosecution and maintenance  activities  undertaken by it. If at any time during
the term of this  Agreement  either  party  elects not to file or to abandon any
patent  or  patent  application  which  such  party  has the  right  to file and
prosecute  pursuant to this Section,  such party shall notify the other party of
that  decision at least 30 days prior to any deadline for the filing of any such
patent  application or any response or the taking of any other action  necessary
to maintain such patent or patent application in existence.  Thereafter,  AS ITS
SOLE AND  EXCLUSIVE  REMEDY  THEREFOR,  such other party shall have the right to
take over  responsibility  for the maintenance of such patent or the prosecution
of such patent application, at its sole expense and discretion.

                           3.4 Except for the  rights  and  licenses  explicitly
granted as stated in this Agreement, each party retains all rights and ownership
in and to its  technology  and  intellectual  properties,  and makes no grant of
rights  by  implication.   It  is  understood   that   Progenitor   retains  the
non-exclusive  right,  without the right to sublicense,  to make, have made, use
and import  the  Licensed  Product  and the  Licensed  Technology  for  research
purposes.

                  4.       FEES AND ROYALTIES.

                           4.1 Novo  Nordisk  will pay  Progenitor  a  quarterly
research fee of U.S.  $[******] during Ligand Stage 2 and/or Growth Factor Stage
2;  provided,   however,   that  during  any  period  in  which   Progenitor  is
simultaneously performing work in Ligand Stage 2 and Growth Factor Stage 2, such
total research fee shall be $[******] per quarter (or a pro rata portion thereof
for any  partial  quarter);  provided  further,  however,  that if,  pursuant to
Section 2.1.5, the Joint Committee authorizes Progenitor to devote less than the
equivalent of fifteen qualified  scientists to the completion of its obligations
hereunder  during any period in which  Progenitor is  simultaneously  performing
work in Ligand Stage 2 and Growth Factor Stage 2, the

research fee to be paid hereunder shall be reduced pro rata according to the
reduced amount of effort (in terms of the number of qualified scientists working
on the project) required to be devoted by Progenitor.

                              4.1.1  Notwithstanding  any of the foregoing,  the
total of all research fees payable by Novo Nordisk  pursuant to this Section 4.1
shall not exceed the following amounts: (i) if Novo Nordisk elects,  pursuant to
Section 2.1.1 and 2.1.3,  to proceed to Stage 2 with a Ligand or Ligands or with
a Growth Factor or Growth  Factors,  but not with both, such research fees shall
not exceed  $4,000,000;  and (ii) if Novo  Nordisk  elects,  pursuant to Section
2.1.1 and 2 1.3,  to  proceed  to Stage 2 with both a Ligand  or  Ligands  and a
Growth Factor or Growth Factors, such research fees shall not exceed $6,000,000.

                              4.1.2 Each such  research  fee shall be due within
60 days after Novo Nordisk's receipt of an invoice therefor,  but no sooner than
the tenth day of each January, April, July, and October; provided, however, that
the first such payment shall be due 60 days after receipt of an invoice therefor
following the  commencement  of the first Stage 2 of the Research  Phase (Ligand
Stage 2 or Growth  Factor  Stage 2), but no earlier  than  [************].  Novo
Nordisk  will not be  obligated to make any research fee payment due on or after
the effective date of any termination of this Agreement.

                           4.2 In addition, if Novo Nordisk elects to go forward
with  development  of a Licensed  Product,  Novo Nordisk  will pay  Progenitor a
license  fee of U.S.  $5,000,000  within 90 days after the  earlier  of: (i) the
delivery to Progenitor of the first Ligand  Development  Notice or Growth Factor
Development  Notice  stating  that  Novo  Nordisk  desires  to go  forward  with
development of a Licensed  Product;  or (ii) the commencement by or on behalf of
Novo Nordisk of  production  of an active  ingredient  for any Licensed  Product
under Good  Manufacturing  Practices  (GMP).  Nothing in this Agreement shall be
construed as requiring Novo Nordisk to pay more than one such license fee.

                           4.3 In addition, Novo Nordisk will make the following
milestone payments to Progenitor:

                              4.3.1  Novo  Nordisk  will  pay  Progenitor   U.S.
$1,000,000 within 60 days after the earlier of (i) the date that, pursuant to an
Investigational New Drug filing, if any, made by Novo Nordisk or an Affiliate of
Novo  Nordisk  for a Licensed  Product,  Novo  Nordisk or an  Affiliate  of Novo
Nordisk is  permitted  for the first time by the FDA to  proceed  with  clinical
testing  of  a  Licensed   Product;   or  (ii)  the  date  of  the  first  human
administration  of a  Licensed  Product  by or on behalf of Novo  Nordisk  or an
Affiliate of Novo Nordisk in any country.  Regardless  of the number of Licensed
Products, nothing in this Agreement shall be construed as requiring Novo Nordisk
to pay any milestone payment pursuant to this Section 4.3.1 more than once.

                              4.3.2  Novo  Nordisk  will  pay  Progenitor   U.S.
$3,000,000  within  60 days  after the first  initiation  of Phase III  clinical
trials (or the first initiation of equivalent

each separate Licensed Product to treat any specific indication.

                              4.3.3  Novo  Nordisk  will  pay  Progenitor   U.S.
$5,000,000 within 60 days after the first Product License  Application  ("PLA"),
New Drug Application  ("NDA") or equivalent filing, if any, made by Novo Nordisk
or an Affiliate of Novo Nordisk for each  separate  Licensed  Product is granted

is granted final approval by the appropriate regulatory authority of Germany, or
the United  Kingdom,  or any  European  central drug agency with  authority  for

                              4.3.5  Novo  Nordisk  will  pay  Progenitor   U.S.

                              4.3.6  Except as set forth in  Sections  4.3.4 and
4.3.5  above,  the  milestone  payments  shall be  nonrefundable  once  paid and

                           4.4 In addition, Novo Nordisk shall pay to Progenitor

<PAGE>

All such Royalties (after allowing credit for advances on Royalties paid
pursuant to Sections 4.3.4 and 4.3.5 and any reduction of royalties pursuant to
Section 4.6) shall be due and payable within 60 days after the end of each
calendar half year for Net Sales received in such calendar half year, as
follows: Within 60 days after the end of each first and third calendar quarter
for which Royalties are payable hereunder (that is, the calendar quarters ending
on March 31 and on September 30 of each such year), Novo Nordisk will submit to
Progenitor a report stating the approximate Net Sales and Royalties due for such
quarter, together with payment of such approximate amount. Within 60 days after
the end of each calendar half year for which Royalties are payable hereunder
(that is, the periods ending on June 30 and on December 31 of each such year),
Novo Nordisk will submit to Progenitor a statement of actual Net Sales for such
half year, separated as to Net Sales within Europe, Japan and all other
countries, and the calculation of Royalties payable hereunder with respect to
such Net Sales, together with payment of all remaining Royalties due with
respect to such Net Sales, as adjusted for any amount previously paid as
approximate Royalties with respect to such Net Sales.

                           4.5 Whether or not a Licensed Product is considered a
"separate  Licensed Product" for purposes of making milestone  payments pursuant
to  Sections  4.3.2  through  4.3.5 and for  purposes of  calculating  Royalties
pursuant to Section 4.4 will be  determined  on the basis of whether or not such
Licensed Product contains any active ingredient different than or in addition to
the active  ingredient(s) in any other Licensed Product.  That is, each Licensed
Product will be  considered  to be a "separate  Licensed  Product" for which any
additional  milestone  payment  is due and for which  Royalties  are  calculated
separately only if such Licensed Product contains one or more active ingredients
not also contained in any Licensed Product for which such milestone  payment has
then already been made or for which Royalties have then already been calculated,
respectively.

                           4.6 If subsequent to the date of this Agreement, Novo
Nordisk determines in its sole discretion, which it will exercise in good faith,
after  consulting with Progenitor with respect  thereto,  that royalties must be
paid to one or more third  parties in order for Novo  Nordisk  to  exercise  the
rights  granted in Section 3.1, each party will share such  third-party  royalty
obligation  as follows:  the royalty  payments by Novo Nordisk under Section 4.4
shall be reduced by  one-half of such third  party  royalties,  except that such
reduction shall be limited so that the royalty paid to Progenitor  under Section
4.4 is not reduced by more than one-half.

                           4.7  All  payments  to be made  by  Novo  Nordisk  to
Progenitor  under  this  Agreement  shall  be made  in  United  States  dollars.
Conversion  of  foreign  currency  to United  States  dollars  for  payments  of
Royalties  shall be made at the  conversion  rate  published  in the Wall Street
Journal,  Eastern  edition,  on the last business day of the calendar quarter to
which such payments relate.

                           4.8 If laws or  regulations  require  withholding  by
Novo Nordisk of any taxes  imposed upon  Progenitor  on account of any Royalties
paid  under this  Agreement,  such taxes  will be  deducted  by Novo  Nordisk as
required by law from such remittable Royalty and


J:\DOCS\BTPM_NY_\46\0035332.02

                                      -15-
<PAGE>

shall be paid by Novo Nordisk to the proper taxing authority. Official receipt
of such taxes shall be secured and sent to Progenitor as evidence of such
payment. The parties will use reasonable efforts to ensure that any withholding
taxes imposed are reduced as far as possible under the provisions of the current
or any future double taxation treaties or agreements between foreign countries
and the parties shall cooperate with each other with respect thereto, with the
appropriate party under the circumstances providing the documentation required
under such treaty or agreement to claim benefits thereunder.

                           4.9 Novo  Nordisk  shall  keep  accurate  records  in
sufficient  detail to enable the amounts of Royalties  due to  Progenitor  to be
determined.  Upon Progenitor's  request and after reasonable prior notice,  Novo
Nordisk shall permit an  independent  certified  public  accountant  selected by
Progenitor  to have access  during  ordinary  business  hours to Novo  Nordisk's
records  necessary to determine  the  correctness  of any report or payment made
with respect to any half year and to obtain information as to the amount payable
to Progenitor for any such period.  Such  examination  shall be at  Progenitor's
expense  and shall not take place more than once each year.  These  rights  with
respect to any year shall  terminate  two (2) years  after the end of such year.
Information  supplied  to  Progenitor  by  such  independent   certified  public
accountant  shall not include any  proprietary  information  not  required to be
disclosed to it under other Sections of this Agreement.  If such accounting firm
concludes that additional Royalties are owed for any half year,  Progenitor will
provide  Novo Nordisk  with access to such  accounting  firm's work product with
respect to such  conclusion,  and Novo  Nordisk  shall have a period of up to 60
days after  receipt of such work product in which to review such  findings.  If,
after such 60-day review period, Novo Nordisk agrees with the conclusion reached
by such accounting firm with respect to such additional Royalties,  Novo Nordisk
shall promptly pay the additional  Royalties  owed. If, after such 60-day review
period,  the parties  are not in  agreement  as to the amount of any  additional
Royalties owed, the parties will negotiate in good faith for a period of 60 days
with  respect  thereto.  If the parties are unable to agree on the amount of any
such  additional  Royalties  owed after such 60-day period of  negotiation,  the
parties  will submit such  question to binding  arbitration  pursuant to Section
9.9.

                  5.       CONFIDENTIALITY.

                           5.1 Each party (the "Receiving  Party")  acknowledges
and agrees that the other party (the  "Disclosing  Party") may, in the course of
performing this Agreement and the parties' other dealings, disclose confidential
information  belonging  to  the  Disclosing  Party  in  writing,  orally  or  by
demonstration  or sample.  All such  confidential  information of the Disclosing
Party shall be maintained  in confidence by the Receiving  Party and will not be
used by the Receiving Party for any purpose except as authorized hereunder.  The
Receiving  Party  shall  exercise  the  same  degree  of  care to  preserve  the
confidentiality  of  such  information  of the  Disclosing  Party  as it uses to
protect its own  confidential  information of similar nature,  and the Receiving
Party shall  safeguard  such  information  against  disclosure to third parties,
including without limitation employees and persons working or consulting for the
Receiving  Party.  This  obligation  of   confidentiality   does  not  apply  to
information and material that:

Receiving Party, without any restriction on use or disclosure,  prior to receipt
from the Disclosing  Party, and such possession can be properly  demonstrated by
the Receiving Party;

                                 (ii) are in the  public  domain by public  use,
publication, general knowledge or the like, or after disclosure hereunder become
general or public knowledge through no fault of the Receiving Party;

                                 (iii) are  properly  obtained by the  Receiving
Party from a third party not under a confidentiality obligation;

                                 (iv)  are  independently  developed  by  or  on
behalf  of the  Receiving  Party  without  the  assistance  of the  confidential
information of the Disclosing Party; or

                                 (v) are  required to be  disclosed  by order of
any court or governmental authority.

                           5.2 The Receiving  Party shall not acquire any rights
with  respect to  confidential  information  disclosed  to it by the  Disclosing
Party,  except as expressly set forth in this  Agreement.  The  Receiving  Party
shall not disclose any  confidential  information of the Disclosing Party to any
third party or to any  employees,  officers or directors of the Receiving  Party
except those who reasonably  require such  disclosure for purposes of performing
the  Receiving  Party's  obligations  under this  Agreement  without  the prior,
written consent of the Disclosing Party.

                           5.3 Upon termination of this Agreement, the Receiving
Party shall return to the Disclosing Party or destroy any tangible copies of any
confidential  information  provided to it  hereunder  by the  Disclosing  Party;
provided,  however,  that  the  Receiving  Party  may  retain  one  (1)  copy of
confidential  information  disclosed  to it  by  the  Disclosing  Party  in  its
confidential legal files for archival purposes.

                           5.4  Each  party  agrees  that it will  not  make any
public  announcement or other publication  regarding any results of the research
conducted  hereunder  before a patent  application  has been filed with  respect
thereto,  except  upon the prior  written  approval  of the other  party in each
instance. In addition, each party will refrain from issuing any press release or
making any public announcement or other publication  regarding this Agreement or
the relationship of the parties hereto,  except for announcements or disclosures
which are required by law to be made, without the prior,  written consent of the
other party in each instance,  which consent will not be unreasonably  withheld.
Progenitor  will also refrain from  publishing or disclosing any  information or
material that is in any way related to this  Agreement or any Receptor,  Ligand,
Growth Factor or Licensed  Product  without the prior,  written  consent of Novo
Nordisk in each instance,  which consent will not be unreasonably withheld. Each
party will  respond to any request for consent  pursuant to this  Section 5.4 as
soon as reasonably possible.

agreement,  partnership,  joint  venture or other  arrangement,  whether oral or
written,  with any third party relating to any Receptor,  Ligand, Growth Factor,
Licensed  Product,   Licensed  Patent  Right  or  Licensed  Technology  that  is
inconsistent with the terms of this Agreement.

                           6.2  Progenitor  represents and warrants that, to the
best of  Progenitor's  knowledge,  the  technology  developed by or on behalf of
Progenitor covered by the Licensed Patent Rights and Licensed Technology,  as it
exists on the date of this  Agreement,  has been made and developed  without the
use of, or infringement  upon, the secrets,  patents or other proprietary rights
or interests of any third party and without the use of any  equipment,  supplies
or  facilities  of any third party that would  create any right to any  Licensed
Patent Right, Licensed Technology or Joint Technology in such third party.

                           6.3 Novo  Nordisk  assumes  all  risks of  damage  or
injury to persons and to property arising out of any manufacture, use or sale of
Licensed  Product  by or on  behalf  of  Novo  Nordisk  and its  Affiliates  and
sublicensees,   and  shall  hold  harmless  and  indemnify  Progenitor  and  its
Affiliates  from and  against  any and all  personal  injury,  property  damage,
product liability or similar claims,  losses and liabilities arising out of such
manufacture, use or sale of Licensed Product, except for such claims, losses and
liabilities caused by a breach of Progenitor's  representations  under any other
Section of this  Agreement  and except as set forth in Section  6.4.  Progenitor
assumes all risks of damage or injury to persons and to property  arising out of
any manufacture,  use or sale of Progenitor  Ligand Product,  Progenitor  Growth
Factor  Product and  Progenitor  Product by or on behalf of  Progenitor  and its
Affiliates and sublicensees,  and shall hold harmless and indemnify Novo Nordisk
and its  Affiliates  from and  against  any and all  personal  injury,  property
damage,  product liability or similar claims, losses and liabilities arising out
of such manufacture, use or sale of Progenitor Ligand Product, Progenitor Growth
Factor Product and/or  Progenitor  Product,  except for such claims,  losses and
liabilities caused by a breach of Novo Nordisk's representations under any other
Section of this Agreement and except as set forth in Section 6.4

                           6.4 Nothing in this Agreement shall be construed as a
warranty,  representation or undertaking with respect to the utility,  efficacy,
nontoxicity,  safety or  appropriateness of using any Receptor,  Ligand,  Growth
Factor,  Licensed  Product  or  any  other  product;  provided,   however,  that
Progenitor  represents and warrants that it has fully disclosed to Novo Nordisk,
and Progenitor  covenants  that it will fully  disclose to Novo Nordisk,  to the
extent

it can do so without violating any obligation of Progenitor and/or any of its
Affiliates to any third party, all data and information in Progenitor's
possession, knowledge or control relating to the use, manufacture, utility,
efficacy, nontoxicity, safety and appropriateness of each Receptor, Ligand,
Growth Factor and Licensed Product. Otherwise, the physical quantities of
materials provided by each party to the other hereunder are provided "as is,"
and neither party makes any representation or warranty of any kind, express or
implied, written or oral, including, without limitation, any representation or
warranty with respect to the value, adequacy, freedom from fault, or the
quality, efficiency, suitability, characteristics, usefulness, merchantability
or fitness for a particular purpose of, such physical quantities of materials,
except as otherwise set forth in this Agreement.

                           6.5      NOVO NORDISK ACKNOWLEDGES THAT, EXCEPT AS
OTHERWISE SET FORTH IN THIS AGREEMENT, THE LICENSES GRANTED BY PROGENITOR IN 
THIS AGREEMENT ARE GRANTED WITHOUT WARRANTY OF ANY KIND.

                           6.6 Each party agrees to indemnify and hold the other
party  harmless  from and  against  any loss,  damage,  liability  and  expense,
including, without limitation,  reasonable attorneys' fees and costs of defense,
arising  out of any  breach  of  such  party's  representations,  warranties  or
covenants under this Agreement.  Progenitor  agrees that Novo Nordisk shall have
the  right  to set off any  such  amounts  owed to Novo  Nordisk  from  fees and
Royalties payable to Progenitor hereunder.

                  7.       INFRINGEMENT.

                           7.1 Except as set forth in Sections 8.5.3,  8.6.3 and
8.7.3,  in the event that any of the  Licensed  Patent  Rights are  infringed or
believed to be  infringed  by a third  party,  Novo  Nordisk may, at its option,
elect to prosecute such infringement  claims. If Novo Nordisk elects to commence
such an action,  Novo  Nordisk  shall have control of such action and shall have
the right to settle or compromise the same, and Progenitor  agrees that it shall
fully cooperate in every reasonable way with the prosecution of such action.  If
Novo Nordisk  elects to commence such an action,  Progenitor  hereby grants Novo
Nordisk the right to do so in Progenitor's name, and, if Progenitor is a legally
indispensable  party to such action, Novo Nordisk may cause it to be joined as a
party in such  action at Novo  Nordisk's  expense.  Novo  Nordisk  shall  notify
Progenitor  of any action  filed by Novo  Nordisk  pursuant to this  Section and
shall keep Progenitor generally informed as to the progress of such action.

                           7.2 Recoveries or reimbursements from any such action
shall first be applied to  reimburse  Novo Nordisk for its  expenses,  costs and
fees in connection with the action. Any remaining  recoveries or reimbursements,
to the extent they  constitute the equivalent of, or damages or payments in lieu
of,  reasonable  royalties  on the  infringer's  sales (but not in excess of the
amount  that would be payable  pursuant  to Section  4.4),  shall be shared with
Progenitor  in accordance  with Section 4.4, and otherwise  shall be retained by
Novo Nordisk as its own property.

                           7.3 In the event  that Novo  Nordisk  decides  not to
commence or continue  prosecution  of an  infringement  of the  Licensed  Patent
Rights pursuant to the above paragraphs, Novo Nordisk will promptly give written
notice of such decision to  Progenitor.  Progenitor  shall  thereafter  have the
right,  but not the  obligation,  to commence or continue such action at its own
expense,  controlling  such action and retaining all  recoveries  therefrom.  If
Progenitor  elects to bring an  action  to  prosecute  the  infringement  of any
Licensed Patent Rights under this Section, Progenitor shall have sole control of
such action and may settle or  compromise  such  action in its sole  discretion,
provided that no such  settlement or compromise  conflicts with any provision of
this Agreement.  If Progenitor  elects to commence such an action,  Novo Nordisk
hereby grants Progenitor the right to do so in Novo Nordisk's name, and, if Novo
Nordisk is a legally indispensable party to such action, Progenitor may cause it
to be joined as a party in such action at Progenitor's expense, and Novo Nordisk
agrees to cooperate  fully in every  reasonable way with the prosecution of such
action.

                  8.       TERM AND TERMINATION.

                           8.1 The  term of this  Agreement  shall  begin on the
date set forth  above  and  shall  continue  until  the  earlier  of the date of
termination in accordance with Section 8.3 or the date of expiration of the last
to expire of any Valid Claim of the Licensed Patent Rights.

                           8.2 Novo Nordisk may terminate  the licenses  granted
to it pursuant to this Agreement with respect to Receptor and all Ligands at any
time during  Ligand Stage 1 or after the end of Ligand Stage 2 upon  delivery of
30 days' written notice to Progenitor, or at any time during Ligand Stage 2 upon
delivery  of 90 days'  written  notice  to  Progenitor.  Novo  Nordisk  may also
terminate the licenses  granted to it pursuant to this Agreement with respect to
all Growth  Factors at any time during Growth Factor Stage 1 or after the end of
Growth Factor Stage 2 upon delivery of 30 days' written notice to Progenitor, or
at any time during  Growth  Factor  Stage 2 upon  delivery  of 90 days'  written
notice to Progenitor. Novo Nordisk may also terminate this Agreement at any time
before the  commencement  of Ligand  Stage 2 or Growth  Factor  Stage 2 or after
termination  of the Research  Phase upon delivery of 30 days' written  notice to
Progenitor,  or at any other time upon  delivery of 90 days'  written  notice to
Progenitor.

                           8.3 Either party may terminate  this  Agreement  upon
120 days' written notice to the other party at any time that such other party is
in  material  breach of any  obligation  hereunder  if such  breach is not cured
within  such  120-day  period.  Neither  party shall be deemed to be in material
breach of this Agreement during any period in which a good faith dispute between
the parties exists regarding performance or breach of its obligations hereunder.

                           8.4  The  provisions  in  this  Agreement   regarding
payment  of  fees  and  Royalties   accrued  as  of  the  date  of  termination,
confidentiality,  indemnification and the provisions set forth in Sections 1, 6,
8.5, 8.6, 8.7, 8.8, 8.9 and 9 shall  survive any  expiration or  termination  of
this Agreement. In addition, Novo Nordisk shall have a continuing, non-exclusive
right to use the Licensed  Technology,  but not to exercise any Licensed  Patent
Rights, following any termination or expiration of this Agreement.

                           8.5  Effective  only  upon  any  termination  of  the
licenses granted pursuant to this Agreement with respect to the Receptor and all
Ligands by Novo  Nordisk  pursuant to Section 8.2 or by  Progenitor  pursuant to
Section 2.1.1, which termination  becomes effective prior to the payment by Novo
Nordisk of the license fee pursuant to Section 4.2,  Novo Nordisk  hereby grants
to Progenitor and its Affiliates the worldwide, sole and exclusive license, with
right to sublicense,  under Novo Nordisk's  rights in Novo Nordisk Ligand Patent
Rights and Joint Technology arising from the research conducted pursuant to this
Agreement in the course of Ligand Stage 1 and Ligand Stage 2 (the "Ligand  Joint
Technology"),  to make,  have made,  use,  sell,  have sold,  offer for sale and
import Progenitor Ligand Product for use in the Field. Novo Nordisk will deliver
to  Progenitor,  within  90 days  after  any  such  termination,  all  materials
constituting  Ligand Joint  Technology  and copies of all data in Novo Nordisk's
possession regarding the Ligand Joint Technology.  If such a termination occurs,

ending on March 31 and on September 30 of each such year), Progenitor will
submit to Novo Nordisk a report stating the approximate Progenitor Ligand Net
Sales and royalties due for such quarter, together with payment of such
approximate amount. Within 60 days after the end of each calendar half year

Ligand Net Sales, as adjusted for any amount previously paid as approximate
royalties with respect to such Progenitor Ligand Net Sales. Progenitor shall
keep, and shall cause its sublicensees to keep, complete, true and accurate
records for the purpose of showing the derivation of all royalties payable to

rights  granted in this Section 8.5, Novo Nordisk  covenants  that it will fully
disclose  to  Progenitor,  to the  extent  it can do so  without  violating  any

                           8.8 Upon Progenitor's request, Novo Nordisk will
negotiate with Progenitor in good faith for a reasonable period of time
following any termination of the licenses granted hereunder and/or of this
Agreement, which termination is effective after the payment by Novo Nordisk of
the license fee pursuant to Section 4.2, regarding a license to Progenitor of
rights under applicable Novo Nordisk Patent Rights and Joint Technology, but the
parties acknowledge that no agreement for a grant of any such license is
included in the terms of this Agreement, and Novo Nordisk shall not be required
to grant any such license nor to do so on any particular terms.

                           8.9 PROGENITOR ACKNOWLEDGES THAT THE LICENSES GRANTED
IN SECTIONS 8.5, 8.6 AND 8.7 ARE GRANTED AS IS, WITHOUT WARRANTY OF ANY KIND,
AND PROGENITOR AGREES TO INDEMNIFY NOVO NORDISK FOR ANY LOSS, DAMAGE, LIABILITY
AND EXPENSE, INCLUDING WITHOUT LIMITATION ATTORNEYS' FEES AND COSTS OF DEFENSE,

OF ANY EXERCISE OF SUCH RIGHTS BY OR ON BEHALF OF PROGENITOR, ITS AFFILIATES
AND/OR ANY LICENSEE OR ASSIGNEE OF PROGENITOR OR AN AFFILIATE OF PROGENITOR.

                  9.       MISCELLANEOUS.

                           9.1 Novo Nordisk shall have complete control, as
between the parties, over the development, manufacture, testing, pricing,
marketing, sale and distribution of any Licensed Product. All trademark and
service mark rights and all goodwill associated with any trademarks and service
marks used by Novo Nordisk and its Affiliates and sublicensees in connection
with Licensed Product shall, as among the parties, belong solely to Novo
Nordisk.

                           9.2 This Agreement constitutes the entire agreement
and supersedes all prior agreements and understandings, both written and oral,
among the parties hereto with respect to the subject matter hereof.

                           9.3 Neither party shall assign or transfer any of its
rights hereunder, or delegate any of its obligations hereunder, to any third
party (other than an Affiliate of such party) without the prior, written consent
of the other party in each instance; provided, however, that (i) either party
may assign all its rights and obligations hereunder to a third party that
acquires all assets of such party associated with the collaboration established
by this Agreement, so long as such assigning party provides the other party with
notice of such assignment at least 30 days before it becomes effective; and (ii)
Novo Nordisk may delegate any duty arising under this Agreement to any third
party so long as Novo Nordisk remains ultimately responsible, as between the
parties, for performance of such duty. This Agreement shall bind and benefit the
parties hereto and their permitted successors and assigns.

                           9.4 All notices, requests, reports and other
communication provided for or permitted hereunder shall be given in writing and
shall be hand delivered or sent by facsimile, reputable courier or by registered
or certified mail, postage prepaid, return receipt requested, to the address set
forth on the first page of this Agreement, or to such other address as a party
may inform the others of in writing. Notices will be deemed delivered on the
earliest of transmission by facsimile, actual receipt or ten days after mailing
as set forth herein.

                           9.5 Any terms of this Agreement may be amended,
modified or waived only in a writing signed by all the parties hereto.

                           9.6 If any provisions of this Agreement shall be held
invalid, illegal or unenforceable, such provision shall be enforced to the
maximum extent permitted by law and the parties' fundamental intentions
hereunder, and the remaining provisions shall not be affected or impaired.

                           9.7 Nothing herein contained shall constitute this a
joint venture agreement or constitute either party as the partner, principal or
agent of the other, this being an

Agreement between independent contracting parties. Neither party shall have any
authority to bind the other party in any respect whatsoever.

                           9.8 This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of Washington,
U.S.A., without regard to its conflict of law rules.

                           9.9 Any dispute arising between the parties relating
to, arising out of or in any way connected with this Agreement or any term or
condition hereof, or the performance by either party of its obligations
hereunder, whether before or after termination of the Agreement, shall be
finally resolved by binding arbitration. Whenever a party shall decide to
institute arbitration proceedings, it shall give written notice to that effect
to the other party. The party giving such notice shall refrain from instituting
the arbitration proceedings for a period of sixty (60) days following such
notice. During such 60-day period, the parties shall make good faith efforts to
amicably resolve the dispute without arbitration. Any arbitration hereunder
shall be conducted under the Commercial Arbitration Rules of the American
Arbitration Association ("AAA"). Each such arbitration shall be conducted by a
panel of three arbitrators: one arbitrator shall be appointed by each of
Progenitor and Novo Nordisk and the third shall be appointed by such two
arbitrators, or, if such two arbitrators are unable to agree on the third
arbitrator within a period of 30 days after appointment of the second of them,
such third arbitrator shall be appointed by the AAA. Any such arbitration shall
be held in New York, New York. The arbitrators shall have the authority to grant
specific performance and to allocate between the parties the costs of
arbitration in such equitable manner as they determine. Judgment upon the award
so rendered may be entered in any court having jurisdiction, or application may
be made to such court for judicial acceptance of any award and an order of
enforcement, as the case may be. In no event shall a demand for arbitration be
made after the date when institution of a legal or equitable proceeding based on
such claim, dispute or other matter in question would be barred by the
applicable statute of limitations.

         IN WITNESS WHEREOF, the parties hereto have caused their duly
authorized officers to execute and acknowledge this Agreement as of the day and
year first above written.
