ITEM 1.    FINANCIAL STATEMENTS

     Attached hereto are Ostex International, Inc.'s (the "Company's or Ostex'")
unaudited condensed balance sheet as of March 31, 1997, and audited condensed
balance sheet as of December 31, 1996, and the unaudited condensed statements of
operations and cash flow for the quarters  ended March 31, 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  Management's  Discussion and Analysis of Financial  Condition and
Results of  Operations  includes a number of  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 on page 3 "Other Factors that May Affect Operating Results" in
this  section,  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 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 MARCH 31, 1997 AND MARCH 31, 1996

       The Company had revenues  from product  sales of $654,000 for the quarter
ended March 31, 1997, compared to $587,000 for the quarter ended March 31, 1996.
The increase in 1997 is  attributable  solely to higher  volumes of  OsteomarkAE
kits sold to foreign  distributors and domestic  laboratories during the quarter
which were offset by decreased  sales to the Company's  domestic  distributor as
orders  were  postponed  during the 1997  quarter in order to bring  distributor
excess inventory  levels of Osteomark Kits in line with customer demand.  During
the three months ended March 31, 1997,  foreign sales increased 28% and sales to
domestic customers increased 7% compared to the same period of 1996.

       The  Company's  cost of products  sold  totaled  $151,000 for the quarter
ended March 31, 1997, compared to $168,000 for the same period of 1996. The cost
of products  sold as a  percentage  of sales for the 1997 first  quarter was 23%
compared  to 29% for the  first  quarter  1996.  The  decrease  is a result of a
decline in unit manufacturing  costs resulting from increased  production volume
that caused  fixed  manufacturing  costs to be spread over the higher  number of
units produced during the first quarter 1997.

       The Company's  research and development  expenditures  totaled $1,078,000
for the quarter ended March 31, 1997, compared to $745,000 for the quarter ended
March 31, 1996.  Funding of research  conducted at the  University of Washington
increased by approximately $196,000 during the 1997 quarter compared to the 1996
quarter.  This  research is focused on molecular  markers of  connective  tissue
degradation,  and on developing  further  understanding of the osteoclast colony
stimulating factor ("O-CSF") as a potential  therapeutic agent. These grants are
expected to continue through 1999.  Regulatory expenses increased  approximately
$136,000  during the first  quarter of 1997 compared to the same quarter of 1996
in connection  with clinical trials that commenced at the end of 1996 and during
the first quarter 1997 for  determination  of variability  and the NTx reference
range in  males,  variability  of NTx in  postmenopausal  women,  and use of the
Osteomark test to help identify bone metastases.



       Selling,  general and administrative  expenses totaled $1,923,000 for the
quarter ended March 31, 1997,  compared to $1,855,000  for the same period ended
March 31, 1996. The higher expense level during the three months ended March 31,
1997 was due to compensation associated with additions to the management team in
the third quarter of 1996,  increased  legal fees  associated  with defending or
bringing  lawsuits and  additional  costs to support the field  selling  effort,
offset by a decrease in outside advertising and professional fees.

       Interest  income  totaled  $249,000 for the quarter ended March 31, 1997,
compared to $412,000 for the quarter  ended March 31, 1996.  The decrease is due
to lower  invested  balances  resulting  from using  cash to fund the  Company's
operating losses.


LIQUIDITY AND CAPITAL RESOURCES

       The Company has financed its operations from inception  primarily through
three  private   placements  of  preferred   stock   aggregating   approximately
$12,800,000 and an initial public offering of 3,645,642  shares of common stock,
which generated net proceeds of approximately  $32,000,000.  Additional funds of
approximately  $13,154,000  have been generated  through sales of Osteomark kits
and  research  testing  services,   and  collaborative  research  and  licensing
agreements.  As of March 31, 1997, the Company had  $18,239,000 in cash and cash
equivalents and short-term investments, working capital of $18,416,000 and total
shareholders' equity of $21,118,000.  During the three month period ending March
31,  1997,  cash,  cash  equivalents  and  short-term  investments  decreased by
$2,990,000,  working  capital  decreased by $2,485,000 and  shareholders  equity
decreased by $2,408,000,  and the Company used  $2,632,000 of cash for operating
activities to fund net losses as compared to  $1,772,000  during the three month
period ended March 31, 1996.

         The Company's  future  capital  requirements  depend upon many factors,
including  effective  commercialization  activities and arrangements,  continued
scientific  progress in its research and development  programs,  progress toward
development of the O-CSF technology, which potentially has therapeutic uses, the
costs involved in filing,  prosecuting  and enforcing  patent claims,  the costs
involved in legal efforts to enforce patent rights and  distribution  contracts,
and the time and costs involved in obtaining  regulatory  approvals.  Additional
funds from equity or debt  financing may be required.  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 at least mid 1998.  In  addition,
although the Company was awarded  $6,400,000 as a result of the arbitration of a
dispute  with  Boehringer  Mannheim  that  amount has not been  received  by the
Company or recognized in the Company's financial statements.  On April 28, 1997,
Boehringer  Mannheim filed a motion in District  Court to vacate the award.  See
Part II, Item 1 entitled "Legal Proceedings" for additional information.

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,
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 and 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 August 25,  1995,  the Company  commenced  an  arbitration  proceeding
against Boehringer  Mannheim for breach of contract.  The hearing before a panel
of the American  Arbitration  Association  ( the "Panel") was held in Seattle on
September 3-11, 1996. On January 28, 1997, Ostex received a final award from the
Panel.  The  Panel  determined  that  Boehringer  Mannheim  breached  a  license
agreement  by  failing  to use its  best  efforts  to  effectively  promote  the
Osteomark MTP kits. Boehringer Mannheim's counterclaims against the Company were
denied by the Panel. The Panel's award instructs  Boehringer Mannheim to pay the
Company  $5,720,000 in damages for lost  profits,  and $700,000 to reimburse the
Company for part of its  attorneys'  fees and expenses.  The award provides that
interest  will be paid on such  amounts,  at the  rate of 8% per  annum,  to the
extent that such amounts  remain unpaid 30 days from January 28, 1997,  the date
of the award. On April 28, 1997,  Boehringer Mannheim filed a motion in District
Court to vacate the award.  The Company  intends to  vigorously  respond to that
motion. The award has not been reflected in the Company's  financial  statements
as of March 31, 1997.

       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.   The  Company  believes
Osteometer's bone resorption immunoassay incorporates technology which infringes
on patented Ostex technology. In September 1996, the defendants filed a response
denying  infringement  and  counterclaimed  that  Ostex'  patent is invalid  and
unenforceable.  The lawsuit is scheduled for trial commencing  December 2, 1997.
At the present  time  management  cannot  predict the outcome of the lawsuit but
intends to continue to vigorously defend its position.

       In April  1997,  the  Company  was  served 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 patents 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  months  ended  March  31,1997,  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 or warrants. These shares are not
included  in the  computation  of net loss  per  share  because  the  effect  of
including such shares would be antidilutive.


2.  RELATED PARTY TRANSACTIONS


LEGAL AND CONSULTING SERVICES

Total operating expenses include legal and consulting fees for services provided
by a related  party  totaling  $50,000 and $18,000 for the quarters  ended March
1997 and 1996, respectively.


3.  CONTINGENCIES


LEGAL PROCEEDINGS

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







4.  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,  the
Company's basic and diluted EPS for the quarter ended March 31, 1997, would both
be a net loss per share of $(0.18).
