ITEM 1.    FINANCIAL STATEMENTS

       Attached hereto are Ostex International, Inc.'s (the "Company's or Ostex'
")  unaudited  condensed  balance  sheet as of September  30, 1997,  and audited
condensed  balance  sheet as of  December  31,  1996,  the  unaudited  condensed
statements of operations for the three months ended September 30, 1997 and 1996,
and for the nine months ended September 30, 1997 and 1996, and the statements of
cash flow for the nine months ended September 30, 1997 and 1996.Notes  follow
the  unaudited  financial  statements  and are an  integral  part thereof.


ITEM 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
           RESULTS OF OPERATIONS

         This Quarterly Report on Form 10-Q contains forward-looking  statements
which  reflect the  Company's  current  views with respect to future  events and
financial performance.  These forward-looking  statements are subject to certain
risks and  uncertainties,  including  those  discussed  below,  that could cause
actual  results  to  differ   materially  from   historical   results  or  those
anticipated.  Words used herein such as  "believes,"  "anticipates,"  "expects,"
"intends,"  and similar  expressions  are  intended to identify  forward-looking
statements but are not the exclusive means of identifying  such  statements.  In
addition,  the  disclosures  under the caption  "Other  Factors  that May Affect
Operating Results", consist principally of a brief discussion of risks which may
affect  future  results  and are thus,  in their  entirety,  forward-looking  in
nature.  Readers  are  urged  to  carefully  review  and  consider  the  various
disclosures  made by the  Company  in this  report  and in the  Company's  other
reports  previously  filed with the  Securities  and  Exchange  Commission  (the
"SEC"),  including the Company's  Annual Report on Form 10-K for the fiscal year
ended December 31, 1996, that attempt to advise interested  parties of the risks
and factors that may affect the Company's business.

COMPARISON OF THE THREE MONTHS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996

       Total revenues were  $1,505,000 for the quarter ended September 30, 1997,
compared to $1,859,000 for the quarter ended  September 30, 1996.  Product sales
were $1,055,000 during the three month period ended September 30, 1997, compared
to  $776,000  for the same period in 1996.  The 36 % increase  was due to higher
volumes  of  OSTEOMARK-registered trademark- kits  sold  to  domestic   
laboratories and foreign  distributors  during the 1997 quarter compared to
the same period of 1996. License and research and development fees were $450,000
during the three month period ended  September 30, 1997,  compared to $1,083,000
during the same period in 1996. The $633,000  reduction in fees collected  under
license and research and development agreements with Mochida Pharmaceutical Ltd.
("Mochida") was expected and is due to attainment of scheduled  milestones.  The
Company  does not expect to receive any  further  milestone  payments  under the
license  agreement with Mochida and future  payments of up to $750,000 under the
research and  development  agreement are contingent  upon Mochida's  decision to
exercise  its option to license the NTx serum assay and  achievement  of certain
serum assay development milestones.

       The  Company's  cost of products  sold  totaled  $228,000 for the quarter
ended September 30, 1997,  compared to $247,000 for the same period of 1996. The
decrease was primarily due to elimination of excess facility costs.  The cost of
products  sold  decreased  as a percentage  of product  sales to 22% in the 1997
third  quarter  compared to 32% in the 1996 third  quarter due to a reduction in
unit  manufacturing  costs resulting from increased  production  volume allowing
fixed  manufacturing  costs to be spread  over a higher  base of units  produced
during the quarter  ended  September  30,  1997,  compared to the same period in
1996.

       The Company's  research and development  expenditures  totaled $1,090,000
for the quarter ended  September 30, 1997,  compared to $757,000 for the quarter
ended  September 30, 1996. The $333,000  increase was primarily  attributable to
the NTx assay point-of-care development programs with Metrika Laboratories, Inc.
("Metrika") and Hologic, Inc. ("Hologic"). In addition, research and development
expenses  increased due to the cost of clinical studies  commenced at the end of
1996 and during the first quarter 1997. Included in the Company's studies in the
1997  quarter  was a study  for the  determination  of  variability  and the NTx
reference  range in males,  a study  for  variability  of NTx in  postmenopausal
women, and a study for the use of the Osteomark test in helping to identify bone
metastases.

<PAGE>

       Selling,  general and administrative  expenses totaled $1,903,000 for the
quarter  ended  September 30, 1997,  compared to $2,328,000  for the three month
period ended  September  30, 1996.  The $425,000  decrease was  primarily due to
completion of the Company's free testing program in 1996 and the completion of a
hearing before the American Arbitration  Association against Boehringer Mannheim
in  September  1996,  partially  offset  by  increased  costs of  litigation  in
connection  with the Osteometer and C.R. Bard cases (see "Legal  Proceedings" in
Part II, Item 1 of this 10-Q). The Company anticipates a substantial increase in
legal expenses in connection  with the Osteometer  patent  infringement  lawsuit
during the fourth  quarter of 1997 as the proceeding  enters a discovery  phase,
and continuing into fiscal year 1998.

       Interest  income  totaled  $196,000 for the quarter  ended  September 30,
1997,  compared to $299,000  for the  quarter  ended  September  30,  1996.  The
decrease is due to lower invested balances resulting from using cash to fund the
Company's operating losses.


COMPARISON OF THE NINE MONTHS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996

       Total revenues were  $3,108,000 for the nine month period ended September
30, 1997,  compared to $3,300,000 for the nine month period ended  September 30,
1996. Product sales were $2,658,000 during the nine month period ended September
30, 1997,  compared to $2,217,000 for the same period in 1996. The 20 % increase
was due to higher  volumes of Osteomark kits sold to domestic  laboratories  and
foreign distributors during the 1997 period compared to the same period of 1996.
License and research and  development  fees were $450,000  during the nine month
period ended September 30, 1997,  compared to $1,083,000  during the same period
in 1996.  The  reduction  in fees  collected  under  license  and  research  and
development  agreements  with Mochida was expected and is due to  attainment  of
scheduled  milestones.  The  Company  does not  expect to  receive  any  further
milestone  payments under the license agreement with Mochida and future payments
of up to $750,000  under the research and  development  agreement are contingent
upon  Mochida's  decision to exercise  its option to license the NTx serum assay
and achievement of certain serum assay development milestones.

       The Company's  cost of products sold totaled  $640,000 for the nine month
period ended September 30, 1997,  compared to $682,000 for the nine months ended
September  30, 1996.  The decrease  was  primarily  due to a reduction of excess
facility  costs.  The cost of products sold decreased as a percentage of product
sales to 24% in the 1997  period  compared  to 31% in the 1996  period  due to a
reduction in unit manufacturing costs resulting from increased production volume
allowing  fixed  manufacturing  costs to be spread  over a higher  base of units
produced during the nine months ended  September 30, 1997,  compared to the same
period in 1996.

       The Company's  research and development  expenditures  totaled $3,522,000
for the nine month period ended  September 30, 1997,  compared to $2,203,000 for
the nine months ended  September 30, 1996.  The increase of $1,319,000 is due to
research spending in connection with the development of NTx assay  point-of-care
devices  under the  development  agreements  with Metrika and Hologic  discussed
above, as well as funding of research conducted at the University of Washington.
Research at the  University  of  Washington  is focused on molecular  markers of
connective tissue degradation,  and on developing a further understanding of the
osteoclast colony stimulating factor ("O-CSF") as a potential therapeutic agent.
This  research  funding is expected  to  continue  through  1999.  In  addition,
research and development  expenses increased due to the cost of clinical studies
commenced at the end of 1996 and during the first quarter 1997.

       Selling,  general and administrative  expenses totaled $5,688,000 for the
nine month period ended September 30, 1997,  compared to $6,695,000 for the nine
months  ended  September  30,  1996.  The  lower  expense  level  was due to the
completion  of a hearing  before the American  Arbitration  Association  against
Boehringer  Mannheim in September 1996 (see "Legal Proceedings" in Part II, Item
1 of this 10-Q),  and the  completion of the Company's  free testing  program in
1996.  However,  the  decrease  was  partially  offset  by  increased  costs  of
litigation in  connection  with the  Osteometer  and C.R. Bard cases (see "Legal
Proceedings" in Part II, Item 1 of this 10-Q). As discussed  above,  legal costs
associated  with the  Osteometer  patent  infringement  lawsuit are  expected to
increase substantially in the fourth quarter 1997, and continue into fiscal year
1998.

<PAGE>

       Interest  income  totaled  $675,000  for  the  nine  month  period  ended
September  30, 1997,  compared to  $1,036,000  for the same period in 1996.  The
decrease is due to lower invested balances resulting from using cash to fund the
Company's operating losses.


LIQUIDITY AND CAPITAL RESOURCES

       As of September 30, 1997,  the Company had  $14,178,000  in cash and cash
equivalents and short-term investments, working capital of $14,214,000 and total
shareholders'  equity of $17,635,000.  As a result of funding  operating  losses
during the nine months ended  September 30, 1997,  cash,  cash  equivalents  and
short-term  investments  decreased by $7,051,000,  working capital  decreased by
$6,687,000 and  shareholders  equity  decreased by  $5,891,000.  During the nine
month  period  ended  September  30, 1997 the Company  purchased  $1,093,000  in
property and equipment, received $124,000 from the exercise of stock options and
paid $121,000 of notes payable.

         In October  1997,  the Company  received  $6,200,000  in  settlement of
certain  litigation  (see "Legal  Proceedings" in Part II, Item 1 of this 10-Q).
The Company did not reflect the settlement in its balance sheet at September 30,
1997.  This will be  reflected  in income and assets  during the quarter  ending
December 31, 1997.

         The Company's  future  capital  requirements  depend upon many factors,
including effective commercialization activities and collaborative arrangements,
continued  progress in its research and  development  programs,  progress toward
development of the O-CSF technology,  the costs involved in filing,  prosecuting
and  enforcing  patent  claims,  and the time and costs  involved  in  obtaining
regulatory  approvals.  The Company may require  additional funds from equity or
debt  financings.  There can be no assurance that such additional  funds will be
available on favorable  terms, if at all.  Because of the Company's  significant
long-term  cash  requirements,  it may  seek  to  raise  additional  capital  if
conditions in the public equity markets are favorable,  even if the Company does
not have an  immediate  need for  additional  cash at that time.  If  additional
financing is not available,  the Company anticipates that its existing available
cash,  its future  license and research  revenues  from  existing  collaboration
agreements,  product sales and interest income from short-term  investments will
be adequate to satisfy its capital  requirements and to fund operations  through
mid 1999.  No assurance can be given,  however,  that such funds will in fact be
adequate until that time, since the Company's  prediction is subject to a number
of  risks  and  uncertainties,   including  those  discussed  in  the  following
paragraph.

OTHER FACTORS THAT MAY AFFECT OPERATING RESULTS

         The  Company's  operating  results  may  fluctuate  due to a number  of
factors  including,  but not  limited  to,  volume and timing of product  sales,
product pricing, market acceptance of the Company's products,  changing economic
conditions in the healthcare industry, delays and increased costs of product and
technology   development,   the  Company's   ability  to  develop  and  maintain
collaborative  arrangements,  the outcome of  litigation,  and the effect of the
Company's  accounting  policies,  as well as other risk factors  detailed in the
Company's 1996 Form 10-K and other SEC filings. All of the foregoing factors are
difficult  for the Company to predict and can  materially  adversely  affect the
Company's business and operating results.


                          PART II -- OTHER INFORMATION


ITEM 1.    LEGAL PROCEEDINGS

       On November 4, 1997, the Company  announced  settlement  with  Boehringer
Mannheim under which the Company received a lump sum payment of $6,200,000.  The
settlement  between  the two  parties is the result of the  previously  reported
January 28, 1997 ruling by the American  Arbitration  Association  in connection
with the Company's claims against Boehringer Mannheim.

<PAGE>

       In June 1996,  the Company filed an action in the United States  District
Court for the Western District of Washington  against  Osteometer Biotech A/S, a
medical  technology  company  based in Denmark  ("Osteometer"),  and  Diagnostic
Systems  Laboratories  Inc. for patent  infringement of United States Patent No.
5,455,179.   The  Company  believes  Osteometer's  bone  resorption  immunoassay
incorporates technology which infringes patented Ostex technology.  In September
1996, the defendants  filed a response denying  infringement and  counterclaimed
that Ostex'  patent is invalid and  unenforceable.  By order dated July 7, 1997,
the Court granted  Ostex's  motion to file a  supplemental  complaint,  to add a
second  cause of action based upon United  States  Patent No.  5,641,837,  which
issued on June 24, 1997. On October 24, 1997, Ostex filed a second  supplemental
complaint to add third and fourth  causes of action  based upon U.S.  Patent No.
5,652,112,  which issued on July 29, 1997, and U.S. Patent No. 5,656,439,  which
issued  on August  12,  1997.  The  lawsuit  is  currently  scheduled  for trial
commencing  June 30, 1998.  At the present time  management  cannot  predict the
outcome  of the  lawsuit  but  intends  to  continue  to  vigorously  assert its
position.

       On April 9, 1997,  the  Company  was served  with a lawsuit  filed in the
United  States  District  Court,  Central  District of  California  by C.R. Bard
("Bard").  The complaint  alleges that Ostex' Osteomark  product  infringes U.S.
Patent No.  4,628,027  assigned to Bard in 1993.  Management  believes that this
suit is without merit and that Ostex' Osteomark product falls outside the claims
of the subject patent.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS



1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:


Basis of Presentation

The  unaudited  condensed  financial  statements  include the  accounts of Ostex
International,  Inc. (a Washington corporation) (the "Company"). These financial
statements have been prepared in accordance with generally  accepted  accounting
principles  for  interim  financial  reporting  and  pursuant  to the  rules and
regulations of the Securities and Exchange  Commission.  While these  statements
reflect  all  normal  recurring   adjustments  which  are,  in  the  opinion  of
management,  necessary  for fair  presentation  of the  results  of the  interim
periods,  they do not include all of the information  and footnotes  required by
generally accepted accounting principles for complete financial statements.  For
further  information,  refer to the financial  statements and footnotes  thereto
included in the  Company's  Annual  Report filed on Form 10-K for the year ended
December 31, 1996.


Net Loss per Common and Common Equivalent Share

For the three and nine months ended September  30,1997,  net loss per common and
common  equivalent  share was  based on the  weighted  average  number of common
shares outstanding during each period.  Common stock equivalents  include shares
issuable upon the exercise of outstanding  stock  options.  These shares are not
included  in the  computation  of net loss  per  share  because  the  effect  of
including such shares would be antidilutive.


2.  CONTINGENCIES


Legal Proceedings

Refer to Part II, Item 1 of this Form 10-Q.


3.  NEW ACCOUNTING PRONOUNCEMENTS


In February 1997, the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting Standards No. 128, Earnings Per Share (SFAS 128), which is
effective for periods  beginning  after December 15, 1997.  SFAS 128 establishes
new  standards  for  computing  and  presenting  earnings per share (EPS).  Upon
adoption of SFAS 128, companies will report basic EPS and diluted EPS instead of
previously reported primary and fully diluted EPS. Under the new standard,  both
the Company's  basic and diluted EPS for the quarter  ended  September 30, 1997,
would be a net loss per share of $.12,  and for the nine months ended  September
30, 1997, both basic and diluted EPS would be a net loss per share of $.49.


4.  SUBSEQUENT EVENTS


         In October  1997,  the Company  received  $6,200,000  in  settlement of
certain  litigation  (see "Legal  Proceedings" in Part II, Item 1 of this 10-Q).
The Company did not reflect the settlement in its balance sheet at September 30,
1997.  This will be  reflected  in income and assets  during the quarter  ending
December 31, 1997.

                           JOINT DEVELOPMENT, LICENSE
                           AND CO-MARKETING AGREEMENT


         This  Joint  Development,  License  and  Co-Marketing  Agreement  (this
"Agreement")  is  entered  into as of the 10th day of  April,  1997  ("Effective
Date"),  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  METRIKA  LABORATORIES,   INC.,  a
California  corporation  having its  principal  place of business at 510 Oakmead
Parkway, Sunnyvale, CA 94086 ("Metrika").

                                    RECITALS

         A.       The Washington Research  Foundation,  a nonprofit  Washington
corporation ("WRF"), is the owner, by way of assignment from the University
of Washington, of all right, title, and interest in certain technology developed
out of research  conducted  by Dr.  David Eyre and  generally  described  as the
"Urinary Assay for Bone Resorption."

         B.  Pursuant  to that  certain  Restated  Exclusive  License  Agreement
between  Ostex and WRF,  effective  June 29,  1992 as amended,  the  ("WRF/Ostex
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 certain of the Bone
Resorption Technology (as defined below).

         C. Ostex engages in the research, development, manufacture, and sale of
diagnostic and therapeutic  products in the field of bone and mineral metabolism
in applications  related to bone  resorption and collagen and connective  tissue
degradation, and has developed a proprietary immunoassay to determine the levels
of NTx epitope  collagen  metabolite  resulting from bone resorption ("NTx Assay
Technology" as further defined in SECTION 1.17 hereof), which it has implemented
in  a  microtiter   format   suitable  for  use  in   centralized   laboratories
("OsteomarkAE Laboratory Test").

         D.       Metrika is developing a single-use  disposable  diagnostic
device featuring Metrika's proprietary Digital ResponseAE technology (the 
"Digital Response Device").

         E. Ostex and Metrika entered into that certain Agreement dated November
4, 1994 (the "Development  Agreement")  pursuant to which Ostex and Metrika have
collaborated in the adaptation of Ostex's NTx Assay for use on Metrika's Digital
Response Device. The product of this  collaboration  shall be referred to herein
as the "NTx/Digital Response Device." The Development Agreement anticipated that
the  parties  would  later  enter  into an  agreement  to  govern  the  ultimate
manufacture, promotion, marketing and sale of the NTx/Digital Response Device.

<PAGE>

         F. The  parties now desire to enter into this  Agreement  to govern the
terms and  conditions  under which the parties will continue the  development of
the NTx/Digital Response Device,  provide for the financing of such development,
and  provide  for  the  manufacture,  co-promotion,  marketing  and  sale of the
NTx/Digital Response Device

         G. In  particular,  Ostex  desires  to  contribute  to  this  continued
development  project  by  granting  to  Metrika a  license  to use the NTx Assay

marketing  plan shall  require each party to spend,  individually,  at least the
XXXXXXX of Gross Profit from Sales of  NTx/Digital  Response  Devices during the
immediately  preceding  Marketing  Year,  provided  further  that if the Product
Management  Committee  is not  able to agree  on a  marketing  plan for any such
subsequent Marketing Year, the marketing plan (including budgetary  allocations)
for the immediately preceding Marketing Year shall be repeated with expenditures
equivalent  to the dollar  expenditures  of such  preceding  Marketing  Year. If
either party does not spend the amount so  designated  pursuant to the marketing
plan for any  Marketing  Year of this  Agreement,  the  other  party  shall,  in
addition to any other remedy  available  to it at law, in equity,  or under this
Agreement,  have the right to add or  subtract,  as the case may be, such amount

manufacturer(s)  shall  deliver to Ostex a "rolling"  forecast of  quantities of
Critical Reagents to be purchased by Metrika and its designated  manufacturer(s)
and supplied by Ostex during each month of the  following  quarter,  and each of
the subsequent  three quarters (the "Rolling  Forecast").  Each Rolling Forecast
shall be considered a purchase order with respect to the  forecasted  demand for
Critical Reagents over the first three months thereof. The forecasted demand for
the first  subsequent  quarter  shall be relied on by Ostex for  purposes of its
manufacturing and supply obligations  hereunder,  but Metrika and its designated
manufacturer(s)  may vary from its initial  forecast for such quarter by no more
than twenty-five percent (25%). The forecasted demand for the final two quarters
of each  Rolling  Forecast  shall be used by Ostex for  planning  purposes,  but
Metrika  and its  designated  manufacturer(s)  shall not be bound by its initial
forecast(s),  nor shall Metrika or its designated  manufacturer(s)  be liable to

                  7.8 PRODUCT  RECALL.  If either party  believes that a product
recall is necessary or appropriate,  it will promptly notify the other,  and the
parties will (unless such recall is required by law) discuss whether such recall
is necessary or appropriate, and shall discuss the manner in which any agreed or
required  recall shall be conducted.  If a recall is not required by law and the
parties  cannot agree  whether the recall is necessary  or  appropriate,  either
party may elect to conduct the recall in question  The parties  shall  cooperate
with each other in  conducting  any such  recall.  All out of pocket  costs of a
required or agreed recall shall be shared equally by the parties,  unless and to
the extent  that such recall is the result of a breach of warranty by one party,
in which case such costs shall be borne by the breaching  party.  All costs of a
recall to which the  parties  have not  agreed  shall be borne by the party that
elects to conduct the recall, provided that if a court of competent jurisdiction
determines  that  said  recall  was  caused  by (i) the fact  that any  Critical
Reagents or the NTx Assay  Technology were in violation of applicable law or the
terms  of this  contract,  Metrika  may  obtain  reimbursement  by  Ostex of all
reasonable  out of  pocket  costs  and  expenses  of such  recall as well as any
attorneys'  fees  related  to such  determination,  or (ii)  the  fact  that any
NTx/Digital  Response Device(s) were otherwise in violation of applicable law or
the terms of this  contract,  Ostex may obtain  reimbursement  by Metrika of all
reasonable  out of pocket costs and  expenses of such  recall.  Each party shall
maintain  complete  and  accurate  records of all  products  sold by it for such
periods as required by law. Nothing in this Section shall be construed to modify
or limit any legal obligation of either party with respect to any recall.

                  7.9  CORRECTIVE   ACTION.   If  any  government   agency  with
jurisdiction  shall request or order any  corrective  action with respect to any
Critical Reagent, or NTx/Digital Response Devices,  including but not limited to
any recall, customer notice, restriction, change, market action, or modification
of the product in question, and the cause or basis for such corrective action is
primarily attributable to a condition, fact, or action that constitutes a breach
by a party of any of its  warranties,  representations  or  covenants  contained
herein,  then such party shall be liable for and shall reimburse the other party
for all costs incurred as a result of such action, including replacement cost of
any product affected thereby.

         8.  BOOKS AND  RECORDS;  AUDITS.  Each  party to this  Agreement  shall
maintain  accurate  books and records with respect to all Critical  Reagents and

will provide the requesting  party or its  independent  public  accountant  with
access,  but no more than once per calendar year,  during regular business hours
and upon reasonable advance prior notice, to all accounting records necessary or
appropriate  to  verify  revenues  and  expenses.   Any  adjustment   determined
appropriate  by such audit  shall be due and  payable  within  thirty  (30) days
following completion of such audit,  together with interest calculated at a rate
equal to the prime lending rate reported in the Wall Street Journal for the last
day of the audited period plus two percent (+2%),  or the maximum  interest rate
then permitted under applicable laws, whichever rate is lower. All fees for such
audits  shall be borne by the  requesting  party unless the audit shows an under
reporting of amounts due pursuant to SECTION 7.5, or an over  reporting of costs
to be reimbursed  pursuant to SECTION 5.5.2 or SECTION 7.6, of five percent (5%)
or more, in which case the costs of said audit shall be borne by the party being
audited.

confidentiality  provisions  substantially  similar to those  contained  in this
Agreement, and (ii) as required by law or to comply with applicable governmental
regulations or court orders.

activities;  (c) each party has  consulted  with or has had the  opportunity  to
consult  with  counsel  and has been  advised  in all  respects  concerning  the
reasonableness of such covenants as to time and scope; (d) Discloser may have no

period of sixty  (60)  days,  during  which  time the  parties  shall  negotiate
reasonable  terms of a license of the Digital  Response  Technology to allow for
Ostex's  continued   commercialization  of  the  Device.  Without  limiting  the
generality of the foregoing,  a "material  breach" or "failure to perform" shall
include without limitation,  any material failure to remit payments,  or failure
to comply with any  financial  reporting  requirement,  or  material  failure to

retain  and may  fully  exercise  all of its  rights  and  elections  under  the
Bankruptcy Code.

                  11.6  MAXIMUM  TERM.  Notwithstanding  any  provision  of this
Agreement to the contrary,  the license granted with respect to the Ostex Patent
Rights  under  SECTION  2 above  shall  terminate  upon  expiration  of the last
remaining Ostex Patent Right covering the NTx/Digital Response Device. Upon such
expiration, Metrika shall be deemed to have a perpetual, royalty free license to

termination.  Alternatively,  Metrika may return Critical Reagents  remaining in
inventory and in good  condition to Ostex for a refund of the original  transfer
price (or for credit toward any amounts due).

                           11.7.4   SURVIVAL  OF  TERMS.   Notwithstanding   any
     other provision herein to the contrary, SECTIONS 3.4, 7.3.5, 7.7-7.8, 8-12,
15.4,  15.5,  and 16-27 of this  Agreement  shall  survive  any  termination  or

of any  amount  in  dispute  shall be  placed  into an  interest-bearing  escrow
account, and upon resolution of the dispute, the substantially  prevailing party
shall be entitled to be paid (1) the disputed amount,  plus (2) interest thereon
during the  suspension at the rate of ten percent (10%) per annum,  plus (3) its
attorneys' fees relating to the dispute.

without  limitation  reasonable  attorneys  fees  and  expenses)  and  penalties
incurred by said party arising out of any Prohibited  Practice committed by said
party or any of its officers, directors, shareholders, employees, or agents.

         For  purposes  of this  SECTION  12,  the  following  shall be deemed a
"Prohibited Practice":  the offer, payment,  promise to pay, or authorization of
the paying of any money, or the offer, giving,  promise to give or authorization
of the giving of anything of value to any officer or employee of any  government
or any department, agency or instrumentality thereof, or any person acting in an

         13.      THIRD-PARTY INFRINGEMENT.

                  13.1 NOTICE OF THIRD-PARTY  INFRINGEMENT.  If, during the term
of this Agreement, either party becomes aware that one or more third parties are
infringing or are threatening to infringe the Ostex Patent Rights or the Metrika
Patent Rights,  said party (the "Notifying Party") shall immediately report such
information to the Product Management Committee and shall provide in such report
all details in said party's  knowledge  or  possession  concerning  the kind and
character of the  infringement  and any other  pertinent  information  that said
party  may have.  At such  time as the  Product  Management  Committee  shall be
satisfied that there exists a reasonable  likelihood of  infringement  of any of
such  Patent  Rights  implicated  by  the  NTx/Digital  Response  Device  by the
manufacture,  use or sale of  diagnostic  devices  based upon the  detection  of
collagen metabolites as measurements of bone resorption (an "Infringement"), the
Product Management Committee shall take such steps, including  notification,  to
place the  putative  infringer  on notice of the  claims of the party  owning or
controlling  the  infringed  patents (the  "Aggrieved  Party").  The form of the
notification and the manner and nature of any communications between the Product
Management  Committee  and the  alleged  infringer  shall be  determined  by the
Product Management Committee.

                  13.2 RIGHT TO SUE. If, sixty (60) days after receipt of notice
of a perceived third-party Infringement, such third-party Infringement continues
and the  Product  Management  Committee  has not decided  that the parties  will
commence legal action or presented to the Aggrieved  Party a plan  acceptable to
the Aggrieved  Party to enjoin or otherwise to resolve such  Infringement,  then
the  Aggrieved  Party  shall be  entitled,  at its own  expense  and for its own
benefit,  to commence an action,  and in such event the Aggrieved Party shall be
entitled  to retain all of the  benefits of such  action.  In the event that the
Product  Management  Committee  does decide to initiate such action on behalf of
the parties,  the parties shall  jointly  pursue such action and shall share the
cost of such action,  including legal cost and any damages awarded therein. Each
party shall assist the other party and  reasonably  cooperate in any such action
at said party's request.

         14.      DEFENSE OF THIRD-PARTY CLAIMS.

                  14.1  METRIKA  DEFENSE OF  THIRD-PARTY  CLAIMS AND  INDEMNITY.
Except for matters disclosed on Attachment 12.2.2 hereto, to the extent that any
claim,  suit, or other legal proceeding is threatened or commenced against Ostex
or WRF that is founded,  in whole or in part, on an allegation  that the Digital
Response Device  necessarily  infringes any trade secret,  patent,  or copyright
belonging to a third party,  Ostex will give Metrika  prompt  written  notice of
such  legal  proceeding  and  Metrika  may elect to assume  sole  control of the
defense to or  settlement  of such  dispute.  Ostex shall  cooperate  fully with
Metrika in any defense, settlement

<PAGE>

or  compromise  made by  Metrika.  Ostex  shall  not enter  into any  settlement
agreement or other voluntary  resolution of any such claim, suit, or other legal
proceeding without obtaining  Metrika's prior written consent thereto.  If Ostex
has complied fully with the  procedures set forth in this SECTION 14.1,  Metrika
will indemnify and hold Ostex harmless from and against any loss, cost,  damage,
or other  expenses  incurred by Ostex as a result of such  claim,  suit or legal
proceeding.  If a  final  injunction  is  obtained  against  Ostex's  use of the
NTx/Digital  Response  Devices,  or if in the  opinion  of Metrika  the  subject
NTx/Digital  Response  Devices are likely to become the subject of a  successful
claim of infringement,  Metrika may, at its option and expense,  (i) procure for
Ostex the right to continue its performance  under this Agreement,  (ii) replace
or modify the NTx/Digital  Response Devices so that they become  non-infringing,
or (iii)  if  neither  (i) or (ii)  are  reasonably  available,  terminate  this
Agreement  without  further  obligation  or  liability.   This   indemnification
provision  shall be null and void and  Metrika  shall have no  liability  to the
extent that any claim is based on any use of the NTx Assay Technology,  Critical
Reagents or Ostex Intellectual  Property or if the NTx/Digital  Response Devices
has been  modified  or tampered  with in any way  without  the  express  written
consent of Metrika,  or if Ostex has any  interest  in the claim,  suit or other
legal proceeding, or any license to any right so asserted.

                  14.2 OSTEX DEFENSE OF THIRD-PARTY CLAIMS AND INDEMNITY. Except
for matters disclosed on Attachment 12.1.2 hereto, to the extent that any claim,
suit, or other legal proceeding is threatened or commenced  against Metrika that
is founded, in whole or in part, on an allegation that the NTx Assay Technology,
Critical  Reagents or Ostex  Intellectual  Property  as used in the  NTx/Digital
Response Device  necessarily  infringes any trade secret,  patent,  or copyright
belonging to a third party,  Metrika  will give Ostex prompt  written  notice of
such legal  proceeding and Ostex may elect to assume sole control of the defense
to or settlement of such dispute.  Metrika shall  cooperate  fully with Ostex in
any defense,  settlement  or compromise  made by Ostex.  Metrika shall not enter
into any settlement  agreement or other voluntary  resolution of any such claim,
suit, or other legal proceeding  without obtaining Ostex's prior written consent
thereto.  If Metrika has complied  fully with the  procedures  set forth in this
SECTION 14.2,  Ostex will  indemnify and hold Metrika  harmless from and against
any loss,  cost,  damage,  or other expenses  incurred by Metrika as a result of
such claim, suit or legal proceeding.  If a final injunction is obtained against
Metrika's  use  of  the  NTx  Assay  Technology,   Critical  Reagents  or  Ostex
Intellectual  Property as used in the NTx/Digital Response Devices, or if in the
opinion  of  Ostex  the  NTx  Assay  Technology,   Critical  Reagents  or  Ostex
Intellectual  Property are likely to become the subject of a successful claim of
infringement,  Ostex may, at its option and expense, (i) procure for Metrika the
right to continue  distributing and/or using the NTx Assay Technology,  Critical
Reagents or Ostex Intellectual Property in the NTx/Digital Response Device, (ii)
replace  or  modify  the  NTx  Assay  Technology,  Critical  Reagents  or  Ostex
Intellectual  Property  so that it (they)  becomes  non-infringing,  or (iii) if
neither (i) or (ii) are  reasonably  available,  accept  return of the NTx Assay
Technology,  Critical  Reagents  or  Ostex  Intellectual  Property  used  in the
NTx/Digital  Response Devices held by Metrika and its distributors in inventory,
and terminate  this  Agreement  without  further  obligation or liability.  This
indemnification  provision  shall  be null  and void  and  Ostex  shall  have no
liability to the extent that NTx Assay  Technology,  Critical  Reagents or Ostex
Intellectual Property have been modified or tampered with in any way without the
express  written  consent of Ostex, or if Metrika has any interest in the claim,
suit or other legal proceeding, or any license to any right so asserted.

<PAGE>

                  14.3 SHARED DEFENSE OF THIRD-PARTY CLAIMS. With respect to any
claim, suit or other legal proceeding threatened or commenced against Metrika or
Ostex  that  is  founded,  in  whole  or in  part,  on an  allegation  that  the
NTx/Digital  Response  Device  infringes any trade  secret,  patent or copyright
belonging to a third party,  which claim,  suit or other legal proceeding is not
covered by the  provisions  of SECTION 14.1 or 14.2 above,  the parties agree to
share control of the defense or settlement of such claim and shall share equally
all  costs  and  liabilities  resulting  from such  claim,  suit or other  legal
proceeding.

         15.      USE OF TRADEMARKS AND TRADE NAMES.

                  15.1 RESTRICTED  RIGHTS TO USE. No provision of this Agreement
shall be interpreted  or construed as conferring  upon either party any right to
use in labeling,  advertising,  marketing,  publicizing  or otherwise  promoting
NTx/Digital  Response  Devices,  any  name,  trade  name,  trademark,  or  other
designation  (or  derivation  thereof) of the other  party  hereto or WRF or the
University of Washington, except as expressly provided under this SECTION 15.

                  15.2 USE OF NAMES  AND  MARKS  IN  LABELING.  As a part of the
marketing plan prepared pursuant to SECTION 6.2 hereof,  the parties shall agree
upon appropriate trademark(s) to be used in connection with NTx/Digital Response
Devices marketed,  promoted,  sold, and/or distributed under this Agreement.  In
the absence of such agreement, the parties agree that Metrika shall affix to the
outer packaging of, and shall include on the package insert for, any NTx/Digital
Response Devices marketed,  promoted,  sold, and/or distributed by Metrika under
this  Agreement,  and in addition to its own trademarks  and names,  one or more
labels displaying with equal prominence to said Metrika trademarks or names, the
statement "An  OsteomarkAE  Assay" or such other trademark or statement as Ostex
shall reasonably request.  Ostex shall also have the right to review and approve
all  claims  relating  to the  intended  use  of  NTx/Digital  Response  Devices
contained in package  inserts and other  promotional  materials,  which approval
shall not be unreasonably withheld.  Each party hereby grants to the other party
a  non-transferable,  non-exclusive  license,  concurrent  with the term of this
Agreement,   to  use  such  statement  and/or   trademark   accordingly  and  in
substantially the same manner as used by its owner; provided, however, that each
such use of such statement  and/or  trademark be accompanied by a printed notice
identifying  the  owner  as the  owner  thereof.  Neither  party  shall  use any
trademark  of the other  party with  respect  to  products  not  covered by this
Agreement. In the event that particular NTx/Digital Response Devices do not meet
the  specifications  or quality  standards  required under SECTIONS 3.4 or 7.3.4
above,  Ostex may cause Metrika to remove all trademarks  from such  NTx/Digital
Response  Devices  and shall  have the right to cancel  the  foregoing  grant of
license to use such  trademarks,  unless  the other  party  promptly  meets such
specifications or quality standards.  Each party shall have the right to receive
and approve the use of its marks in any proposed product literature, advertising
material or material for  publication.  In all such materials  unless  otherwise
specifically  agreed in advance in writing,  the  immunoassay  performed  by the
NTx/Digital Response Devices shall be identified as "An OsteomarkAE Assay."

<PAGE>

                  15.3 TRADEMARK  REGISTRATION.  Ostex and Metrika shall each be
responsible  for  the   registration,   maintenance  and  enforcement  of  their
respective  names,  trade names, and trademarks;  provided,  however,  that each
party  shall  aid the  other  in the  enforcement  of  that  party's  rights  by
monitoring for, and notifying said party of, any unauthorized use of any of said
party's  trademarks.  Each party shall from time to time,  and in any event upon
the  issuance  of  additional  registrations,  modify its use of  trademarks  to
incorporate  proper  notice  of  registration  and other  claims  of  right,  in
accordance  with the laws  and  customs  of the  various  countries  in which it
operates pursuant to this Agreement.

                  15.4 OSTEX  REPRESENTATIONS  AND WARRANTIES.  Ostex represents
and warrants, as of the date of this Agreement, that: (a) Ostex is the owner and
registrant of the  trademarks  issued  registrations  as indicated by ATTACHMENT
15.4;  (b)  Ostex is named as  applicant  in  those  applications  indicated  by
ATTACHMENT  15.4 as pending;  and (c) to the best of its knowledge,  none of the
Ostex trademarks infringes upon the trademark,  trade name, or other proprietary
rights of a third party. In the event that any action or proceeding is initiated
against Ostex,  Metrika, or any other licensee or distributor of either party in
any country  alleging  that the  trademark  "Osteomark"  infringes the trademark
rights of the third  party  initiating  such action or  proceeding,  Metrika may
continue to market NTx/Digital  Response Devices within such country without the
trademark  "Osteomark"  affixed  thereto (but with such other trademark as Ostex
may  reasonably  specify)  pending  resolution  of the  dispute as to  trademark
rights.

                  15.5   METRIKA   REPRESENTATIONS   AND   WARRANTIES.   Metrika
represents and warrants, as of the date of this Agreement,  that: (a) Metrika is
the owner and registrant of the trademarks issued  registrations as indicated by
ATTACHMENT  15.5;  (b)  Metrika  is named  as  applicant  in those  applications
indicated by ATTACHMENT  15.5 as pending;  and (c) to the best of its knowledge,
none of the Metrika  trademarks  infringes  upon the  trademark,  trade name, or
other  proprietary  rights of an third  party.  In the event  that any action or
proceeding  is  initiated  against  Metrika,  Ostex,  or any other  licensee  or
distributor  of Metrika  in any  country  alleging  that any  Metrika  trademark
infringes  the  trademark  rights of the third party  initiating  such action or
proceeding,  Ostex may continue to market  NTx/Digital  Response  Devices within
such country without said Metrika trademark affixed thereto (but with such other
trademark as Metrika may reasonably  specify) pending  resolution of the dispute
as to trademark rights.

         16.      ASSIGNMENT AND SUBLICENSE.

                  16.1 BY  METRIKA.  Except as  specifically  permitted  by this
Agreement,  Metrika  shall not  assign,  sublicense,  delegate,  or in any other
manner transfer any of its rights, privileges,  obligations or duties under this
Agreement to any third party without the prior written  consent of Ostex,  which
consent may be withheld in Ostex's sole and absolute  discretion,  provided that
this  provision  shall  not  apply  to any  merger,  consolidation,  or  sale of
substantially all of the assets of Metrika, or any third-party  acquisition of a
majority of the business  interests or voting  shares of Metrika,  provided that
the surviving party shall within a reasonable period following the final closing
of such  transaction,  expressly agree in writing to be bound by this agreement.
Any attempt by Metrika to assign, sublicense, delegate or otherwise transfer any
right,  privilege,  obligation  or  duty  under  this  Agreement  other  than in
accordance with this SECTION 16 shall be void and shall, at the option of Ostex,
be cause for immediate  termination of this  Agreement and all licenses  granted
hereunder.

<PAGE>

                  16.2  BY  OSTEX.  Except  as  specifically  permitted  by this
Agreement, Ostex shall not assign, sublicense,  delegate, or in any other manner
transfer  any of its  rights,  privileges,  obligations  or  duties  under  this
Agreement to any third party without the prior written consent of Metrika, which
consent may be withheld in Metrika's sole and absolute discretion, provided that
this  provision  shall  not  apply  to any  merger,  consolidation,  or  sale of
substantially  all of the assets of Ostex, or any  third-party  acquisition of a
majority of the business interests or voting shares of Ostex,  provided that the
surviving party shall within a reasonable  period following the final closing of
such transaction, expressly agree in writing to be bound by this agreement.
 Any attempt by Ostex to assign, sublicense,  delegate or otherwise transfer any
right,  privilege,  obligation  or  duty  under  this  Agreement  other  than in
accordance  with  this  SECTION  16 shall be void and  shall,  at the  option of
Metrika,  be cause for immediate  termination of this Agreement and all licenses
granted hereunder.

         17.      ARBITRATION.

                  17.1  AGREEMENT  TO SETTLE  DISPUTES  BY  ARBITRATION.  At the
request  through  notice of either Ostex or Metrika,  any  controversy  or claim
arising  between the parties and related to or arising out of the  construction,
interpretation, or enforcement of any term or condition of this Agreement or any
transaction  hereunder  (including  the decision to enter into this  Agreement),
which  controversy or claim cannot first be settled amicably between the parties
(including  without  limitation  through  utilization of  third-party  mediation
agreed to by both parties), shall be submitted to arbitration.  Such arbitration
shall be conducted in Seattle,  Washington,  if initiated by Metrika,  or in San
Francisco,  California,  if  initiated  by Ostex,  and in either  case  shall be
conducted in accordance  with the applicable  Rules of the American  Arbitration
Association in effect on the date of such controversy or claim.

                  17.2 APPOINTMENT OF ARBITRATORS. Within thirty (30) days after
the  delivery  pursuant  to  SECTION  17.1  above of a  notice  of  request  for
arbitration,  Metrika and Ostex shall each appoint one independent  person as an
arbitrator to hear and determine the dispute. The two persons so chosen shall by
agreement select a third,  impartial arbitrator,  which selection shall be final
and  conclusive  upon both parties.  Each  arbitrator  shall be  experienced  in
international and domestic manufacturing and distribution of products similar to
NTx/Digital  Response Devices. If either party fails to designate its arbitrator
within sixty (60) days after the notice of  arbitration  is  received,  then the
arbitrator  designated  by the one party  shall act as the sole  arbitrator  and
shall be deemed to be the single,  mutually  approved  arbitrator to resolve the
dispute.

                  17.3 ARBITRATORS'  POWERS.  The arbitrators shall have all the
powers  of a State or  Federal  Court  located  at the site of the  arbitration,
including the power to order specific enforcement of this Agreement and to order
the  production  of  relevant  and  non-privileged  documents  by one  party for
inspection and duplication by the other party prior to the arbitration  hearing;
provided,  however,  that the arbitrators  shall be bound by this Agreement with
regard to the restriction on consequential,  incidental, and punitive damages as
set forth in this Agreement.

<PAGE>

                  17.4  DISCOVERY.  The  arbitrators  prior to the hearing shall
grant  discovery  pursuant  to the  intendment  of the  Federal  Rules  of Civil
Procedure,  and  as  the  arbitrators  determine  to be  appropriate  under  the
circumstances.

                  17.5 PROTECTIVE  ORDER. In the event of arbitration and at the
request of either Ostex or Metrika, in order to protect Confidential Information
and any other  matter  that  either  party  would  normally  not reveal to third
parties,  the  arbitrators  shall enter a  protective  order in such form as the
parties shall stipulate or as the arbitrators shall determine is suitable. Among
other  things,  the  protective  order  shall  stipulate  that  the  arbitrators
themselves  shall  receive  any  information   designated  by  either  party  as
"confidential"  solely for purposes of assessing  the facts and law for purposes
of the arbitration,  and shall not otherwise use or disclose such matter. At the
request of either party,  the  protective  order shall be entered as an award of
the arbitration  panel and shall enable either party to obtain the assistance of
a court of competent  jurisdiction to enter equitable decrees or other relief to
enforce the provisions of the order as if it had been entered by that court.

                  17.6 EFFECT OF DECISION. The decision of the arbitrators shall
state the reason for the award and shall be final,  binding and conclusive  upon
the parties.  The parties shall comply with such decision in good faith as if it
were a final  decision of a court.  Judgment  upon the award shall be entered in
any court of  competent  jurisdiction.  Any award  made in  connection  with any
arbitration shall be made in U.S. Dollars.

                  17.7 RIGHTS OF THIRD PARTIES. Notwithstanding the agreement to
arbitrate any dispute between Ostex and Metrika, in the event that a controversy
or claim between Ostex and Metrika  involves an  adjudication of the rights of a
third party,  and that third party does not agree to submit to  arbitration  and
would under Rule 19(a) of the Federal Rules of Civil Procedure,  if feasible, be
joined as an  indispensable  party,  then the  dispute  shall be brought to, and
determined by, a court of the competent jurisdiction.

                  17.8 INTERIM  RELIEF.  Upon the application of either party to
this  Agreement,  and  whether or not an  arbitration,  mediation  or attempt to
settle amicably has yet been initiated,  all courts having jurisdiction over one
or more of the  parties are  authorized  to: (i) issue and enforce in any lawful
manner such temporary  restraining  orders,  preliminary  injunctions  and other
interim  measures  of relief as may be  necessary  to prevent  harm to a party's
interests  or  as  otherwise  may  be  appropriate  pending  the  conclusion  of
arbitration  proceedings pursuant to this Agreement;  and (ii) enter and enforce
in any lawful manner such  judgments for  permanent  equitable  relief as may be
necessary  to  prevent  harm  to a  party's  interests  or as  otherwise  may be
appropriate   following  the  issuance  of  arbitral  awards  pursuant  to  this
Agreement.

warranties  contained  herein or (iii)  any of its  negligent  or  intentionally
wrongful acts or  omissions.  Metrika  shall  promptly  notify Ostex of any such
demand or claim which comes to its attention.

                  20.2 METRIKA LIABILITY.  Metrika shall be liable for and shall
indemnify  and hold Ostex  harmless  against any  liability  or damages from any
claims, suits, proceedings,  demands,  recoveries or expenses in connection with
(i) any  NTx/Digital  Response  Device sold by Metrika to Ostex pursuant to this
Agreement  arising  out of,  based on, or caused by  product  claims or  selling

where  such  product  claims or  selling  efforts  were not  approved  by Ostex,
including  without  limitation  expenses of total or partial  product recalls as
described  in SECTION  7.8  hereof,  or (ii) any breach by Metrika of any of its
representations or warranties  contained herein or (iii) any of its negligent or
willful  acts or  omissions.  Ostex shall  promptly  notify  Metrika of any such
demand or claim which comes to its attention.

                  20.3   CONSEQUENTIAL,   INCIDENTAL,   AND  PUNITIVE   DAMAGES.
Notwithstanding  any other provision of this  Agreement,  neither party shall be
liable to the other party for any special, consequential, incidental or punitive
damages  that may arise out of this  Agreement  (including  but not  limited  to
damages for loss of sales,  potential  sales,  profits or business),  other than
pursuant to its obligations  under SECTIONS 20.1 and 20.2 above to indemnify the
other party  where such other  party has  incurred  liability  to a  third-party
claimant for special, incidental,  consequential or punitive damages, regardless
of whether  such other  party has been  informed  of the  possibility  that such
damages may occur.
