                               RESEARCH AGREEMENT

         This RESEARCH AGREEMENT is entered into as of the 1st day of September,
1996, by and between OSTEX INTERNATIONAL, INC., a Washington corporation, having
its principal place of business at 2203 Airport Way South,  Suite 400,  Seattle,
Washington  98134  ("Ostex"),  and the  UNIVERSITY  OF  WASHINGTON,  having  its
principal office at Seattle, Washington 98195 (the "University").

                                    RECITALS

         A.  Ostex  has an  ongoing  interest  in  certain  research  technology
(including  inventions,  processes,  formulae  and  the  like,  whether  or  not
patentable,  and property eligible for copyright  protection)  entitled "Role of
O-CSF in Osteoclast  Regulation," as more particularly  described in "Exhibit A"
attached hereto (the "Technology").

         B. The Technology has been assigned by the University to the Washington
Research  Foundation  ("WRF") pursuant to Section 3.3 of that certain Technology
Administration Agreement, dated January 1, 1985, between the University and WRF,
as amended  (the "UW  Agreement").  Pursuant to that certain  Exclusive  License
Agreement between Ostex and WRF, dated October 20, 1989 (the "Exclusive  License
Agreement"),  WRF granted Ostex an exclusive,  worldwide  license to make,  have
made, assign, sublicense,  lease, develop, enhance, modify, produce,  reproduce,
demonstrate,  market,  promote,  sell,  distribute,  use,  exploit and otherwise
commercialize and prepare derivations of the Technology.

         C. Ostex and the  University  entered into a Research  Agreement  dated
November  1,  1992,  pursuant  to which  Ostex  funded  the first two years of a
research  program to be conducted by the  University  relating to the Technology
(the "Research Program").

     D. It is in the  mutual  interest  of  Ostex  and the  University  that the
Research Program be continued pursuant to this Agreement.

         E. Ostex is willing to fund  the XXXXXXXXXXX of the Research Program at
and  through  the  University  of  Washington,   Department  of  Biological
Structure, and the University desires to obtain such funding, all subject to and
in accordance with the terms and conditions set forth in this Agreement.

each six-month interval of the Program Period.

         5.       PRINCIPAL INVESTIGATOR

         For purposes of this Agreement,  and pursuant to University policy, Dr.
Minako Y. Lee is designated the principal  investigator of the Research  Program

Ostex with reports  within thirty (30) days  following the end of each six-month
interval of the Program Period. The University shall furthermore submit to Ostex
a  written  and  comprehensive  final  report  within  ninety  (90)  days  after
termination of the Research Program.

                  7.2  At  the  discretion  and  convenience  of  the  Principal
Investigator during the course of the Research Program,  Ostex's representatives
and others  designated by Ostex may be present as observers while various tests,
inspections  and other  aspects of the  Research  Program  are being  conducted.
Ostex's  representatives may consult informally with the Principal  Investigator
regarding the Research Program both personally and by telephone.  The University
acknowledges  and  agrees  that  the  Principal  Investigator  may  serve  as  a
consultant to Ostex during the term of this Agreement.

                  7.3 From its own  resources  and  those  provided  under  this
Agreement,  the University  agrees to make available  laboratory  facilities and
equipment for the Research Program.

B) BACKGROUND AND SIGNIFICANCE:

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
responsible  for  bone   resorption.   It  is  now  well  established  that
Ostoeclasts  are  derived  from  a   hematopoietic   stem  cell  population  and
multinucleated  functional  osteoclasts  are formed by the fusion of mononuclear
precursor  cells  (1,2).  Although it has been  clearly  shown that  osteotropic
hormones such as 1,25  dihydroxyvitamin  D3 (vitamin D3) or parathyroid  hormone
(PTH) play  important  roles in the process of functional  osteoclast  formation
(3), mechanisms of immature  osteoclast  development in the bone marrow is still
poorly understood. Nonetheless, recent studies have gradually revealed that more
and  more  complex  mechanisms  are  involved  in  differentiation  of  immature
osteoclasts from the heterogenous hematopoietic cell population.  Involvement of
not only various interleukins, colony stimulating factors (CSF), growth factors,
and/or  hormones but also soluble  receptors of cytokines (4) and marrow stromal
cell elements have been  suggested to play roles at various stages of osteoclast
development (3).XXXXXXXXXXXXXXXXXXXXXXXXXXX
