                BONE CARE INTERNATIONAL, INC., AND SUBSIDIARY
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 (Unaudited)

(1)     BASIS OF PRESENTATION

   The consolidated financial statements presented herein have been prepared by
Bone Care International, Inc. (the "Company"), without audit except for balance
sheet information at June 30, 1998, pursuant to the rules of the Securities and
Exchange Commission for quarterly reports on Form 10-Q and do not include all
of the information and note disclosures required by generally accepted
accounting principles for annual financial statements.  These statements should
be read in conjunction with the consolidated financial statements and notes
thereto for the year ended June 30, 1998, included in the Company's Form 10-K
as filed with the Securities and Exchange Commission on September 30, 1998.

    In the opinion of management, the information included herein reflects
all adjustments (consisting of normal, recurring adjustments) necessary for
a fair presentation of results for these interim periods.  The results of
operations for the interim periods ended March 31, 1999, are not necessarily
indicative of the results to be expected for the entire fiscal year ending
June 30, 1999.

(2)     COMMON STOCK

   In July 1998, the Company completed a directed public offering of 1,326,000
shares of common stock at a price of $8.00 per share.  The Company received
proceeds of approximately $10.568 million from the sale, net of offering
expenses. Certain directors of the Company purchased 276,000 of the shares
sold.

(3)     NET LOSS PER SHARE

   Basic loss per share is computed by dividing net loss by the weighted
average number of shares of common stock outstanding during the period.
Diluted per share data is not presented as the effect of potentially issuable
common shares would be antidilutive.
















Item 2.      Management Discussion and Analysis of Financial Condition and
- ------       Results of Operations

Results of Operations
- ---------------------
   Research and development expenses decreased to $1,063,851 in the three
months ended March 31, 1999, from $1,085,993 in the three months ended March
31, 1998 and to $2,737,794 in the nine months ended March 31, 1999 from
$3,061,783 in the nine months ended March 31, 1998.  Prior year research and
development expenses included synthesis and formulation research costs to
commercially produce Hectorol (trademark). These efforts were substantially
completed during the six months ended December 31, 1998.  The resulting reduced
research and development expenses were largely offset by increased regulatory
filing and compliance expenses.

   Marketing, general and administrative expenses increased $524,044 to
$761,421 in the three months ended March 31, 1999, from $237,377 in the three
months ended March 31, 1998.  In the nine months ended March 31, 1999,
marketing, general and administrative expenses increased $1,675,191 to
$2,263,567 from $588,376 in the nine months ended March 31, 1998.
Substantially all of the increases were attributable to pre-marketing
activities relating to the expected launch of Hectorol.

   Interest income increased $47,482 to $123,472 in the three months ended
March 31, 1999 from $75,990 in the three months ended March 31, 1998. Interest
income increased $152,109 to $437,292 in the nine months ended March 31, 1999
from $285,183 in the nine months ended March 31, 1998.  Increased cash balances
resulted from receipt of the net proceeds from the common stock offering
completed during July 1998. The increases in interest income were due to higher
average cash balances during the periods subsequent to the common stock
offering.

Liquidity and Capital Resources
- -------------------------------
   In July 1998, the company completed a directed public offering of 1,326,000
shares of common stock at a price of $8.00 per share. In July 1998, the Company
received proceeds of approximately $10.568 million from the sale, net of
offering expenses.  Prior to June 30, 1998, approximately $298,000 of offering
expenses were incurred.  Certain directors of the Company purchased 276,000 of
the shares sold.

   The Company requires substantial funds for its research and development
programs, preclinical and clinical testing, operating expenses, regulatory
processes and manufacturing and marketing programs.  The Company's capital
requirements depend on numerous factors, including the  progress of its
research and development programs; the progress of preclinical and clinical
testing; the time and cost involved in obtaining regulatory approvals; the cost
of filing, prosecuting, defending and enforcing any patent claims and other
intellectual property rights; competing technological and market developments;
changes and development in the company's existing licensing relationships and
the terms of any new collaborative, licencing, co-promotion or distribution
arrangements that the Company may establish; the progress of commercialization
and marketing activities; the cost of manufacturing preclinical and clinical
products; and other factors not within the Company's control. The Company
believes that the current level of cash and cash equivalents should be
sufficient to fund its operations through at least March 2000.

   Cash and equivalents were $8,464,406 at March 31, 1999 and $3,484,374
at June 30, 1998.  The increase was primarily due to the receipt of net
proceeds of $10,567,504 from the July 1998 common stock offering.  During
the nine months ended March 31, 1999 and 1998, cash used in operating and
investing activities aggregated $5,639,142 and $3,439,288, respectively.
The increase is attributable to Hectorol inventory  production activity
commenced in fiscal 1999 and pre-marketing activities related to the
expected introduction of Hectorol.


Year 2000 Compliance
- --------------------
   Many currently installed computer systems and software products are coded to
accept only two-digit entries in the date code field.  To distinguish
transactions occurring prior to January 1, 2000 from those occurring after
December 31, 1999, these date code fields must be able to accept four-digit
entries.

   The Company has reviewed its existing financial and other business
information systems and believes that its computer systems will be able
to manage and manipulate all material data involving the transition from
1999 to 2000 without functional or data abnormality and without inaccurate
results related to such data.

   It is possible that third parties such as suppliers or contract research
institutions may not have compliant computer systems or programs which may not
interface properly with the Company's computer systems or which may otherwise
result in a disruption of the Company's operations.

   The Company currently anticipates that the expenses and capital expenditures
associated with its year 2000 compliance program will not have a material
effect on its financial position or results of operations.  Although the
Company believes that it will be able to achieve year 2000 compliance through
its efforts, there can be no assurance that these efforts will be successful.
The Company could be adversely affected if it or third parties fail to
successfully achieve year 2000 compliance.  In particular, a disruption to the
Company's commercialization efforts for Hectorol could  have a material effect
on the Company's financial position or results or operations.


Item 3.      Quantitative and Qualitative Disclosure About Market Risk
- ------
   The Company believes that presently it does not have a substantive
disclosure with respect to quantitative and qualitative disclosures about
market risk.  As the Company's operations expand, the Company will consider
such disclosures.

Item 1.      Legal Proceedings
             -----------------
                  The Company may be a defendant from time to time in
             actions arising out of its ordinary course of business
             operations.  The Company believes that none of the matters
             in which it is currently involved, either individually or
             in the aggregate, is material to the Company.

Item 2.   Changes in Securities and Use of Proceeds
          -----------------------------------------
               In connection with a directed public offering of
          1,326,000 shares of common stock (the "Offering") in 1998,
          the Company filed a Registration Statement on Form S-1, SEC
          File No. 333-43923 ("Registration Statement"), which was
          declared effective by the Commission on July 22, 1998.  The
          net proceeds from the Offering to the Company after total
          expenses was $10,270,000.

               The Company intends to use the net proceeds of the
          Offering to fund research and development, including
          preclinical and clinical activities in support of
          regulatory approvals, for commercialization activities
          related to Hectorol for treatment of secondary
          hyperparathyroidism associated with ESRD and for working
          capital and general corporate purposes.

               Through the period ended March 31, 1999, the Company
          has used less than $2,200,000 of the net proceeds for such
          purposes.  The net proceeds not yet utilized have been
          invested in short-term, investment grade, interest-bearing
          financial instruments. The use of proceeds from the
          Offering does not represent a material change in the use of
          proceeds described in the prospectus which is part of the
          Registration Statement.

               Safe Harbor Statement Under the Private Securities
          Litigation Reform Act of 1995:  Certain statements in this
          filing, and elsewhere (such as in other filings by the
          Company with the Securities and Exchange Commission, press
          releases, presentations by the Company or its management
          and oral statements) constitute "forward-looking
          statements" within the meaning of the Private Securities
          Litigation Reform Act of 1995.  Such forward-looking
          statements involve known and unknown risks, uncertainties,
          and other factors which may cause the actual results,
          performance or achievements of the Company to be materially
          different from any future results, performance, or
          achievements expressed or implied by such forward-looking
          statements.  Such factors include, among others, the
          Company's early stage of development, the Company
          dependence on its ability to obtain regulatory approval of
          Hectorol, the uncertainty of the Company's future
          profitability, the uncertainty of regulatory approvals of
          any drugs developed by the Company, the uncertainty of the
          Company's patent positions and proprietary rights, the
          uncertainty related to pricing and reimbursement of the
          Company's products, the intense competition in the
          pharmaceutical and biotechnology industries, the Company's
          potential need for additional partners or collaborators,
          the Company's future capital needs and uncertainty of
          additional financing, and the Company's lack of
          manufacturing capabilities and limited sales and marketing
          experience.  Readers should also carefully review the risk
          factors set forth in other reports or documents the Company
          files from time to time with the Securities and Exchange
          Commission, including Part I, Item 1 of the Company's

          readers are cautioned not to place undue reliance on such
          forward-looking statements.  The Company disclaims any
          obligation to update any such factors or to publicly
          announce any revisions to any of the forward -looking
          statements contained herein to reflect future events or
          developments.
